Accepted Grant Applications

Use this page for an overview of all public grants and their status. Use the sidebar to navigate directly to a specific grant application document.

info

This page provides an overview of accepted grant applications, their progress, and a link to their GitHub repositories. In cases where the link points to an organization, you should be aware that the grant application itself is often an independent project unrelated to other work done by the teams.

Furthermore, the page lists terminations that happened due to a breach of the terms of the grants programs. Additionally, teams might have decided to stop working on the grantโ€”though not necessarily on the project itselfโ€”for various reasons, which is not reflected on this sheet.

Besides, there is a clear difference between an application being accepted and the successful delivery of the respective project, and only teams that have successfully delivered a milestone are allowed to make public announcements on the matter or to use our badge. The badge can also never be used as a general endorsement for a team. Violations to this policy can be reported here.

Project Overview ๐Ÿ“„โ€‹

Overviewโ€‹

Advertising in Metaverse

AdMeta is a Metaverse advertisement platform that focuses on privacy-preserving. AdMeta uses a TEE-based DID service to identify target groups for advertisers, and with the usage of TEE, AdMeta guarantees not to collect any user data. AdMeta builds multiple forms of ad assets (e.g. billboards, wall paintings) in Metaverse platforms like Decentraland, Bit.Country, to allow land holders to integrate our products easily. Qualified conversions let both users and publishers get rewards from advertisers.

In Polkadot and Kusama ecosystem, DID projects like Litentry are growing fast along with its related products. We have already discussed and agreed on our initial cooperation with Litentry. Also, we have contacted with Metaverse projects like Bit.Country, who shows great interests in cooperation as well.

Unlike traditional ad platforms, who collect users sensitive data(e.g. location, browsing history) for advertising, AdMeta does not collect or store any user data per se. Instead, users voluntarily decide and control what data can be stored in TEE, and the stored data in TEE cannot be accessed by anyone except users themselves.

Project Detailsโ€‹

AdMeta Demo - the floating billboard

In the above image, the floating billboard is our prototype ad component built with decentraland SDK. Users who registered on our blockchain, and switched "Ad Display" option on (by default it's off) are able to see a customized ad content on this billboard while gaming in decentraland.

The content of this ad component is selected according to user's personal data and preference. Unlike centralized ad platforms, we don't store user's data on or database. Instead, it's stored on the TEE layer of blockchain, and the target group matching and selecting happen also in the TEE layer, which ensures that no private data are exposed during the whole process. Eventually, both user and publisher receive some amount of token as rewards from advertiser.

Our blockchain is built with Substrate, and the pallet-ad provides the functionality of advertisement proposal, storage and governance. The user pallet will connect to TEE-based external identity aggregation and DID service provided by Litentry (we have already the initial cooperation plan) to match ads with users data and preference.

Architectureโ€‹

AdMeta Architecture

Advertisers can propose an ad with certain acceptance rule, e.g. link clicking, and also advertiser provides how many times the ads are displayed and converted, and how much they pay for each conversion. They need to pay the total price (the number of conversions * price per conversion) while proposing the ad. Each ad display has a unique ID, which is generated while creating the proposal. A Merkle tree are built with all these unique IDs, and the root of Merkle tree will be stored in on-chain storage. A qualified conversion gives the participated user this UID, with which the user can claim for rewards.

Councils shall approve or reject ad proposals according to the content of ads. Also, advertisers are evaluated on their behavior democratically.

Users can switch on the "Ad Display" option on AdMeta, so that users can get rewards by viewing and interacting with ads. By default, this option is off, which means users who haven't set up their AdMeta won't see any ads. Users can also provide their data for a better ad matching, by means of this they will get more rewards.

Publishers can simply utilize our Ad Assets on any Metaverse platform and place it on their lands. Users also get rewards by a qualified display conversion.

Technology Stackโ€‹

  • Substrate
  • Node.js
  • 3D Model Design

Ecosystem Fitโ€‹

There are an increasing number of Metaverse related projects in Polkadot/Kusama ecosystem, however, the current Metaverse platforms still lack of infrastructures and applications, comparing to our current real life. We therefore build this for various Metaverse platforms.

Our target audiences can be Web3 projects, who are potential advertisers, Metaverse land holders, who are potential publishers, and Metaverse players, who are potential users.

Advertising is our natural needs in almost all social scenarios, and we meet this needs in Metaverse.

Parami builds Web3 ad platforms as well, and their scope is to build the DID and privacy layer by themselves. While we are focusing on the advertising functionality, and the DID service will be provided by Litentry, who is more professional on this field and has already their products. Also, our ad platform is targeting on Metaverse, not Web3.

  • Total Estimated Duration: 1 months
  • Full-Time Equivalent (FTE): 2 FTE
  • Total Costs: 12,000 USD

Milestone 1 โ€” Substrate Chain with Impression Ad, Web Appโ€‹

  • Estimated duration: 6 month
  • FTE: 2
  • Costs: 12,000 USD
NumberDeliverableSpecification
0a.LicenseGPLv3
0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.
0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
0e.ArticleWe will publish an article/workshop that explains our advertising workflow as well as technical details.
1.Substrate module: adWe will create a Substrate module that will allow advertiser to create impression ads, and with council's approval, this ad will be ready to be displayed. If ads are rejected by the council(e.g. illegal or pornographic content), the advertiser's proposal bond will be slashed and collected in treasury.
2.Substrate module: user mockWe will create a Substrate module that will first store users data on chain, to test and verify our logic. Also, user can update their data, control what data should be used, and these data are used to find the best matching ad for user.
3.Substrate chainModule ad and user can be integrated into a substrate node, to enable users access of all approved ads, receive rewards, etc. This chain will integrate treasury, council, democracy and also other essential pallets, to build a full-featured blockchain.
4.Web AppWe will create a web app, to let users easily interact with our substrate node. Users can claim rewards from viewing and clicking ads, and they can also configure their ad preferences and decide if they are willing to view ads or not.

The next step is to have sensitive data stored in TEE. Also, we will build more ad types, like click ads and acquisition/action ads. Meanwhile, we will implement a Chrome extension to simplify the claim process, and an Ad asset on Decentraland(or other Metaverse platform) to enable land holders to use our ad assets conveniently.

In a long run, we will cooperate and adapt our products with more Metaverse platforms, and also we will develop more creative and interactive ad types.

Project Overviewโ€‹

Overviewโ€‹

The price volatility of cryptocurrencies is a major blocker for mass adoption. Their rapid change in fiat-denominated value causes payment values to vary even during settlement times, being highly inconvenient to merchants that handle them.

Stablecoins are cryptocurrencies with an exchange rate peg with existing fiat currencies or a fiat-related index, thereby drastically increasing their usefulness as a payment medium.

Although there exists a wide variety of stablecoin mechanisms, some are with censorship risks or some are still suffered from price volatility.

Algo Cash specifically uses an algorithmic approach to manage the supply of tokens according to a predetermined logic. The algorithm is in charge of balancing stablecoin supply to fluctuating demand, ensuring that the token price remains relatively stable.

Integrationโ€‹

Algo Cash is implemented as a smart contract which can be deployed into ink! pallet of a parachain.

For trading and liquidity purpose, Algo Cash could be integrated with such protocols in Polkadot as Konomi and Zenlink.

Project Detailsโ€‹

Tokensโ€‹

ALC - Algo Cashโ€‹

Algo Cash tokens are designed to be used as a medium of exchange. The built-in stability mechanism expands and contracts their supply, maintaining their peg to the aUSD token.

ALB - Algo Bondsโ€‹

Algo Bonds are minted and redeemed to incentivize changes in the Algo Cash supply. Bonds are always on sale to Algo Cash holders, although purchases are expected to be made at a price below 1 Algo Cash. At any given time, holders are able to exchange their bonds to Algo Cash tokens in the Algo Cash Treasury. Upon redemption, they are able to convert 1 Algo Bond to 1 Algo Cash, earning them a premium on their previous bond purchases.

Bonds do not have expiration dates. All holders are able to convert their bonds to Algo Cash tokens, as long as the Treasury has a positive ALC balance.

ALS - Algo Sharesโ€‹

Algo Shares loosely represent the value of the Algo Cash network. Increased demand for Algo Cash results in new Algo Cash tokens to be minted and distributed to Algo Share holders, provided that the Treasury is sufficiently full.

Holders of Algo Share tokens can claim a pro-rata share of Algo Cash tokens accumulated to the Boardroom contract.

Poolsโ€‹

Treasuryโ€‹

The Algo Cash Treasury exists to enable bond-to-cash redemptions. Bonds redeemed via the Treasury automatically returns the user an equal number of Algo Cash, provided that: 1) the oracle price of Algo Cash is above 1 aUSD, and 2) the Treasury contract has a positive balance of Algo Cash.

Disallowing redemptions when the Algo Cash price is below 1 aUSD prevents bond holders from prematurely cutting their losses and creating unnecessary downward pressure on the price of ALC.

Boardroomโ€‹

The Boardroom allows Algo Share holders to claim excess Algo Cash minted by the protocol. Holders of Algo Shares can stake their Shares to the Boardroom contract, which by doing so, they can claim a pro-rata share of Algo Cash tokens assigned to the Boardroom.

Stabilization Mechanismโ€‹

The Algo Cash protocol is designed to guarantee Algo Cash tokens to be exchanged at a value of a single US dollar, with the stabilizer (in-protocol stability mechanism) in charge of matching the supply of Algo Cash to their demand.

Every 24 hours, the time-weighted average of the ALC-aUSD exchange rate is read from the DEX Aggregator in Polkaot, which is then fed into the Algo Cash protocol to be referenced by its stability mechanism.

The stabilization mechanism is triggered whenever the price of Algo Cash is observed to be above / below (1+ฮต) aUSD, where ฮต is a parameter that defines the range of price stability for the ALC token. In inilization, ฮต is set to be 0.05.

Contractionary Policyโ€‹

At any point in time, Algo Bonds can be bought from the protocol in exchange for Algo Cash. Purchase of Bonds are performed at an algorithmically set price. With a Algo Cash oracle price of P aUSD, bonds are sold off at a price of P ALC (effective price being P^2 aUSD), promising bond holders a premium when redeemed. Purchased bonds can be converted to Algo Cash, insofar as the preconditions are met and the Treasury is not empty.

Expansionary Policyโ€‹

If the price of Algo Cash is observed to be higher than (1+ฮต) aUSDT, the system mints totalSupply *(oraclePrice-1) number of new Algo Cash tokens. The issued Algo Cash is either deposited to the Treasury or the Boardroom, depending on the Algo Cash balance of the Treasury.

If the Treasury has a balance above 1,000 Algo Cash, then it is logical to assume that either all bonds have been already redeemed, or no bond holder is currently willing to perform a redemption.Either way, this signals that the demand for bond redemption do not exist at this time, and thus the freshly minted Algo Cash is given to the Boardroom contract.

However, if the Treasury has a balance of below 1,000 Algo Cash, then it is assumed that there will be additional demand for bond-to-cash redemption. Therefore, the issued Algo Cash is routed to the Treasury so that Bond holders can exercise redemptions.

Token Distributionโ€‹

Initial distribution of Algo Cash are done to those that deposit aUSD to the distribution contract. A total of 100,000 Algo Cash tokens are distributed to depositors, with 10,000 Cash tokens distributed per day. The amount of stablecoin deposits are limited to 20,000 tokens per account.

Afterwards, a total of 1,500,000 Algo Shares are on crowd sale and the initial token price would be 40 aUSD. The crowd sale will last for 15 days. Afterwards, ALS will be listed on the DEXs with the same price as in the crowd sale, all funds raised in the crowd sale will be distributed to the DEX as buy orders and all Share tokens left will be distributed as sell orders.

Further distribution of Algo Shares are given to liquidity providers (e.g. ALS-DOT pair, ALS-aUSD pair, etc.) or ecosystem contributors. A total of 500,000 Algo Shares are distributed over a period of 1 year, and an equal amount of tokens are distributed per day.

Advantages

  1. Funds in the crowd sale will not be abused, but used to establish the liquidity market.

  2. Regardless of the funds raised, sufficient selling liquidity can be provided to facilitate large amounts of funds to enter the market.

  3. Compared to joint curve issuance: a fair start, avoiding scientists from rushing

  4. Compared to AMM 2 pool mining: inflation tokens are not required to pay liquidity rents, and tokens are distributed to investors instead of those who "dig, sell and withdraw".

  5. Compared to auctions: Crowd sale is compatible with auction functions, but it is not just a simple fundraising. After the crowd sale is over, a market with abundant liquidity will be established immediately. Even having not raise enough funds, a market with sufficient selling liquidity can still be established, which AMM cannot do.

    Apron Network

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Introductionโ€‹

    The Apron Network's vision is to be the entry point of the Web3 World in the future. The goal of the Apron Network is to create the decentralized infrastructure for all the developers who want to build applications on top of the blockchain, the service providers who are running nodes for blockchain, and the users who are using applications based on blockchain.

    The blockchain infrastructure services are provided by seldom centralized service providers. Those service providers are commercial companies and earn profit by providing these services. In general speaking, there is no problem with such a business model that commercial companies provide infrastructure services and get paid by developers or users in the past ages. But NOT NOW. The main feature of blockchain is decentralization, while all the blockchain infrastructure services are built and maintained by commercial companies, and those systems are centralized, which is against the decentralization of blockchain. There is a potential issue of such a business model that the service providers can steal the blockchain from the community by manipulating the API accesses through their infrastructure services. Once the service providers manipulate the API accesses, there is no real blockchain anymore.

    Maybe you are still thinking that it sounds terrible but no one can prove it. Let's see the recent accident of infura.io. Almost all of the blockchain applications mainly rely on the API services from infura.io, but none of the builders of blockchain applications can imagine what will happen if infura.io manipulates the API services. Hopefully, infura.io worth our trust according to past services, and there is no manipulation found yet.

    On Nov. 11th, 2020, the API services from infura.io are down, and the idea of Apron Network comes out.

    The Apron Network is built by the Apron Labs powered by Substrate. It provides a Cross-chain Decentralized Infrastructure Services Network that will be used by blockchain node runners, DApp developers, the public chain community, and DApp users. Every DApp developer can discover the proper service provider for a specific blockchain through the decentralized infrastructure market on the Apron Network. The Apron Network can be run as a parachain of Polkadot.

    With the Apron Network, the DApp developers can find their API endpoint, node runners can provide infrastructure services to get profit and all the infrastructure services will be decentralized on the two-layers infrastructure service network. The Apron Network will guaranty there is no infura.io accident anymore!

    Integrationโ€‹

    The Apron Network can be run as a parachain on Polkadot, or an independent chain. The Apron Network contains Apron Node and Apron Market. The Apron Node is built with Substrate 2.0 Framework, and the OCW (Off-chain worker) will be included for API manage records. Apron Market consists of Apron Market Contracts and Apron Market Front End. The contracts will be implemented with Ink!, and the front-end will be built with polkadot.js.

    Team Interestโ€‹

    Most of the team members are DApp developers who suffer from the lacking of Ethereum API Endpoint and tightly rely on infura.io since we are not able to set up our full node due to funds. As we have known, most of the DApp developers have the same embarrassing situation as us. After shocked by the accident of infura.io, we are willing to build a decentralized infrastructure service network, and we name it the Apron Network.

    With Substrate 2.0 Framework, we are able to build a customized blockchain network easily, and we have the ability to integrate an API Gateway to manage blockchain API services in Apron Node. With the Apron Network, the blockchain node runners can provide Infrastructure service easily and get profit through this decentralized infrastructure services network.

    Project Detailsโ€‹

    Architectureโ€‹

    The Apron Network consists of Apron Node, Arpon Market Contracts, Decentralized API Market, and the Apron SDK.

    img

    • The Apron Node is the customized chain node for the Apron network built with Substrate 2.0. Besides blockchain-related features, it contains the full features of an API Gateway in the early versions. In future versions, more infrastructure features will be added. It should be run together with the blockchain node and operate by blockchain node runners. For example, the owner of the Ethereum Full node can set up an Apron Node to interact with his Ethereum Full node through RPC, then the DApp developer can retrieve the information of his Apron Node from the Apron Network, and call the API like calling an API with infura.io.
    • The Apron Market Contracts manage the API services information, the registration of API services, the registration of API users, and the billing of API usage. All the API information is stored in these contracts. The billing feature is implemented, the API users have to pay $ANT to use these APIs and the API owners will get paid by $ANT. Everything is done through smart contracts. $ANT is the native token in Apron Network.
    • Decentralized API Market lists all the API services registered and available for developers from the data in smart contracts. DApp developers search the API services according to their needs and choose the one with the proper price.
    • The Apron SDK makes the use of Apron Network easier. DApp developers can integrate this SDK in their app to dynamic switch blockchain entry-point according to their needs.

    Substrate / Polkadot Integrationโ€‹

    The Apron Network can be run as a para-chain of Polkadot, and also can be run as an independent chain apart from Polkadot.

    The whole network is built on top of the Substate 2.0 Framework, and OCW (off-chain worker) is used to report API usage statistics on which the billing relies.

    All the contracts will be implemented with Ink!, and the front-end of Decentralized API Market will be on top of polkadot.js.

    Scenariosโ€‹

    • Node Runners

    img

    The above figure shows the role of each component act from the view of the blockchain node owner. To simply the scenario, we take an example. The para-chain node is running at the beginning, the Apron Node shown above is set up by the owner by staking some $ANT, and the Apron Node is accessible on the internet. The owner can configure Apron Node with the RPC entry point of the para-chain node, API access frequency, API access fee, and other limitations. After everything is configured, the Apron Node will be able to call the RPC interface of para-chain, and DApps will call the API through the Apron Node. The Apron Node calculates the API usage statistics of each caller, then stores this data through OCW (off-chain worker) on the chain for further billing.

    • DApp Developers

    img

    For DApp developers, there are two components that will be used. One is the Decentralized API Market, the other one is the Apron SDK. Firstly, DApp developers search the API services in the API service repositories ( which is part of the Decentralized API Market) on the webpage. After finding the proper API service, the DApp developer will generate an API access key with the help of Apron Market Contracts. Finally, the DApp developer develops the DApp with the API access key to use the related API services. Of course, the DApp developer should pay the fee of using the API services according to the fee addressed by the API service provider.

    Interface Specificationโ€‹

    The function provided by the pallet to report API usage statistics data is reportAPIUsage.

    1. reportAPIUsage

    - desc: Report the API usage statistics from API Gateway data.
    - params: API Key
    - return: the calls number

    Ecosystem Fitโ€‹

    Infura.io is the typical infrastructure services provider that is totally centralized.

    The Apron Network provides exactly the same API services as infura.io but in a decentralized way, thanks to Substrate 2.0 Framework which let us only focused on the logic on top of blockchain rather than re-develop a new blockchain. In the future, the Apron Network will provide a decentralized infrastructure services network.

    Awesome Polka

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Awesome Polka - the ultimate social platform for discovering and exploring the most exciting projects in the Polkadot ecosystem! Whether you're a developer, investor, or simply a curious enthusiast, Awesome Polka provides a one-stop-shop for accessing comprehensive and detailed applications about the projects. With this cutting-edge platform, you can discover the latest updates and developments, connect with project owners, and stay up-to-date with the most innovative projects in the Polkadot community.

    Project Detailsโ€‹

    Project showcase platforms face several challenges that hinder their effectiveness in promoting and highlighting various projects. The most significant challenges include sustainability and limited ecosystem partner (admins - authorized ones like someone from a DAO) authorities on the platform. These challenges significantly affect user experience and discourage project owners and ecosystem partners from utilizing the platforms fully. To address these issues, there is a need to develop innovative and user-centric strategies that enhance the functionality and sustainability of showcase platforms.

    General overview of Awesome Polka:

    Awesome_Polka_Mindmap

    Problemsโ€‹

    Let's take a closer look at some of the issues of project showcase platforms that I have encountered:

    Sustainability: The long-term sustainability of a platform depends on its ability to consistently deliver value to its users. Manual updates to listed projects through forms and limited content control can result in outdated or inaccurate information, reducing user trust and engagement.

    UI & UX: The user experience (UX) of a website or platform can significantly impact user engagement and satisfaction. Poorly designed UIs, slow loading times, confusing navigation, and other factors can all contribute to a low UX, hence reducing user engagement.

    Poor Search Algorithms: A platform showcasing tens of projects will require an effective search algorithm to help users easily find the specific project they are looking for. Weak search algorithms can result in irrelevant search results, leading to frustration and decreased user engagement.

    Static Project Pages: A project page should provide detailed information about the project, such as its objectives, methodology, team members, progress, and impact. A page that only includes a brief description can leave users with unanswered questions and reduce their interest in the project.

    Educational Materials & Articles: For users interested in a particular project, educational materials and related articles can provide valuable context and additional information. Making these resources easy to find and linking them directly to the relevant project pages can enhance user engagement and interest.

    Ecosystem Partner Rights: Partnerships with DAOs or other ecosystem partners can bring significant benefits to a platform, such as increased visibility, funding, and community support. However, without proper rights and access, these partners may not be able to fully leverage their resources and expertise to help the platform grow and succeed.

    Solutionsโ€‹

    Awesome Polka is a social platform that aims to benefit the broader Polkadot developer ecosystem in several ways. Firstly, as Polkadot is one of the fastest-growing protocols, having a platform like Awesome Polka that aggregates all the projects in the ecosystem can help to further increase its size and diversity.

    Additionally, Awesome Polka provides a fluent user experience that enables more people to stay informed about what's happening on Polkadot. By making it easy to access detailed information about projects and events, Awesome Polka helps to promote collaboration and engagement among developers and enthusiasts alike.

    Finally, the platform will be continually supported through Twitter sharing and events, ensuring that it remains a vibrant hub of activity within the Polkadot ecosystem.

    Awesome Polka provides solutions to the problems mentioned in the previous statements in the following ways:

    Solution to Sustainability

    Awesome Polka has 2 personas for managing the platform: Project owners that want to publish their project on Awesome Polka, and ecosystem partners that is authorized ones like someone from a DAO, or from Polkadot team.

    Project owners can send a request to publish their project. After review and approval, they will receive login information to publish and edit their project's page via their web3 wallets on a special dashboard. This enables project pages to be updated by project owners all the time and have unique dynamic pages.

    On the other side, ecosystem partners can have admin access to Awesome Polka. They can approve or reject projects and request to remove any harmful content with an explanation. This allows ecosystem partners to help manage Awesome Polka and ensure that all projects are aligned with sustainability goals.

    In summary, Awesome Polka provides a platform where project owners and ecosystem partners can work together to create long-term sustainable platform. By empowering project owners to create and manage their own projects and providing ecosystem partners with the tools to manage and monitor the platform, Awesome Polka helps to create a sustainable future for all.

    Improvement on UI & UX

    Awesome Polka has a simple and effective user interface that makes it easy to navigate the website and find the information you are looking for. With just a few clicks, users can access general information and project details on the platform. The user interface has been designed to be fresh and cross-platform compatible, which ensures a seamless and enjoyable user experience regardless of the device or browser used.

    The platform is continually undergoing UI developments to enhance the user experience further. At the final stage of development, the user interface will be fully responsible and optimized for all screen sizes, ensuring that users have a consistent and enjoyable experience across all devices. Overall, Awesome Polka prioritizes usability and user experience to create a platform that is both informative and easy to use.

    Solution to Poor Search Algorithms

    Awesome Polka has a powerful search infrastructure that uses Algolia to deliver detailed and lightning-fast search results.

    On Awesome Polka, category list exist to organize projects in detail. Ecosystem partners can add categories to this category list according to ecosystem needs, while project owners can select their category and subcategory while adding their project to the platform. Awesome Polka automatically integrates new categories into relevant pages to increase search efficiency.

    Moreover, Awesome Polka's search infrastructure uses a detailed searching matrix. Unlike most showcase platforms that only use titles to search for anything, Awesome Polka's range of parameters is much wider, ranging from titles to project descriptions. This ensures that users can find what they are looking for more easily and with greater precision.

    In summary, Awesome Polka's search infrastructure is designed to provide a seamless and efficient user experience. Additionally, ecosystem partners work to ensure that the platform's categories are up-to-date and relevant to the needs of the community, further enhancing the search experience.

    Search ElementSearch Focused

    Solution on Static Project Pages

    On Awesome Polka, project owners can manage their project pages, which include several modules such as:

    • Project Description
    • Token Stats
    • GitHub Stats
    • Team Info
    • Latest Articles
    • Frequently Asked Questions
    • Job Postings

    The number of these modules will be increased and further developed.

    Project owners can update their project page using these modules. In the future, additional modules can be added based on the needs of the ecosystem.

    In summary, project pages on Awesome Polka are highly customizable, allowing project owners to showcase their projects using a variety of modules. By providing these modules, Awesome Polka enables project owners to provide up-to-date information about their projects and engage with the ecosystem more effectively.

    Improvement on Educational Materials & Articles

    Awesome Polka offers a platform for project owners to publish educational materials and articles to inform and engage with the ecosystem. With the built-in editor, project owners can create compelling content that keeps their audience up-to-date on the latest developments in their projects. By providing these tools, Awesome Polka helps to create a more informed and engaged community.

    Improvement on Ecosystem Partner Rights

    Ecosystem partners play a crucial role in ensuring the sustainability of the Awesome Polka platform. By giving them admin rights, they can help manage the platform and ensure that it meets the needs of the community. The committee responsible for this role will be selected based on their ability to review and manage projects effectively.

    Project Description ๐Ÿ“„โ€‹

    The lack of options for loans collateralized by NFTs is the consequence of the larger challenge of NFT liquidity and defining the NFT assetsโ€™ price. The same problem fungible (ERC-20) tokens faced before AMMs (automated market makers) were introduced. Once it is solved and an efficient price discovery mechanism is created, NFTs backed loans will experience a boom.

    In the overall market, loans can release asset values and provide the NFT with much-needed liquidity.

    The existing NFT lending platforms in the market, including NFTfi, UpShot One, NFT20, and other projects, all adopt the P2P lending model. The disadvantages are that there is no NFT price evaluation mechanism, and it is difficult for debtors and creditors to find the exact matching businesses. In addition, NFT liquidity is extremely limited. So, the lenders have to bear a lot of risks in P2P lending.

    Overviewโ€‹

    Banksy Finance is a decentralized AI-driven NFT Pool-based lending hub, dedicated to addressing the issues of the NFT market, providing a complete solution for NFT mortgage lending that is different from the P2P lending model. It supports mortgage NFT for loans directly on the platform, without requiring both lenders and borrowers to an agreement. It is the first NFT pool-based lending platform in the market.

    • NAK Protocol

      Banksy Finance first integrated AI technology in the NFT market and provided a reliable NFT pool-based lending solution to address the issues for the market.

      Banksy has developed a set of AI-driven NFT AI KIT, which is an NFT market-based artificial intelligence algorithms toolset, referred to as the NAK protocol. The NAK protocol includes the following features:

      1. Base Analysis: It will timely collect and analyse the data from different Chains, including NFT creator information, attributes, historical transactions, media coverage, community status, popularity, and other information for evaluation of NFT value trend and NFT public opinion trend.

      2. Originality Check: Banksy would extract all NFT characteristics to compose corresponding feature vectors, calculate NFT feature Hash value by the encryption algorithm, and carry out Originality Check for all created NFT.

      3. AI-Assisted NFT Creation: Banksy uses an AI algorithm of image style migration to generate NFT of specified style and content to help artists create better and faster.

      4. AI Oracle For NFT: Banksy integrates the data Analysis results of Base Analysis, uses a machine-learning algorithm to calculate the NFT price in real-time, and feeds the price to oracle.

    • NFT lending pool

      Based on the NAK protocol, Banksy built the NFT pool-based lending platform to provide effective funds security for lenders and meet the needs of NFT holders and lenders.

      Lenders: Users are welcome to deposit their funds (like ETH, USDT) in the Lending Pool for earning interest. The funds will exchange for c-tokens and mortgages for a loan of other mainstream tokens. They will also get the rewards of Banksy native tokens KSY.

      Borrowers: Users can mortgage NFTs in the mortgage contract and get a reference price through AI Oracle. Exchange for corresponding c-tokens to mortgage and take a loan from Lending Pool. It helps to get flexible cash flow for borrowers

      Liquidator: When the Health Factor was closed to 1 that means the collateral value is not properly covered by the value of the loan, the liquidation risk NFTs will be list out for all users. Users can pre-pay as liquidators and get the NFTs when the Health Factor falls below 1 to initiate liquidation. They will receive the KSY tokens as incentives.

    Project Detailsโ€‹

    • NFT Pool-based mortgage lending

    arch

    To ensure the healthy and sustainable NFT mortgage lending business development on the platform, Banksy has designed the following mechanisms:

    1. Whitelist

      By community voting, the pool-based lending business will support series of NFT works, such as the CryptoKitties series and the Bored Ape Yacht series. Introduce high-quality NFT works to eliminate worthless NFT works, thereby ensuring the quality of the NFT works in the platform and ensuring the security of the funds.

    2. Mortgage Rate

      By NAK protocol, the mortgage rate intelligently changes according to the multi-dimensional comprehensive evaluation and analysis of lending, loan demand, and NFT valuation of the whole platform to maintain a reasonable and healthy boundary.

    3. Lending Rate

      The lending rate will intelligently change according to the borrowing demand, capital stock, interest rate fluctuation, and so on to ensure the liquidity and safety of the funds through the NAK protocol.

    4. Liquidation mechanism

      NAK protocol will real-timely monitor and analysis the comprehensive data of collateral NFT to make value anticipation. When the NFT price fluctuates to affect the safety of lending money, the NAK protocol will notify the system to trigger the liquidation mechanism. All users of the Banksy platform will have the right to participate in the liquidation for a lower price and benefit from the liquidation. Meanwhile, we will also reward users for participating in the liquidation.

    5. Safety fund pool

      We set up a Safety Funds Pool where users can stake KSY and KSY/ETH trading pairs in the pool for revenues and rewards from the platform. In case of capital loss, the safety funds pool will use up to 30% of the assets locked to cover the deficit. It will ensure the funds when the shortfall event occurs.

    6. Platform revenue sharing

      Since the users are taking certain risks for staking their funds, Banksy will give incentives and platform revenue to stakes.

      The open and transparency of NFT transaction data in the chains allow access to historical transactions, NFT attribute information, NFT creator information, and NFT popularity information (including Twitter attention, major media NFT attention). It will facilitate a comprehensive analysis of NFT value and trend forecast.

      Banksy will aggregate all the transaction data, take the transaction price and experts estimate as to the machine learning labels of sample data, and take all the relevant data of NFT as sample attribute data for the model training through machine learning algorithms. It will set out a reasonable model of machine learning.

      The real-time attribute data of NFT is used as the model input to predict the NFT price with the machine learning model. It finally multiples with a valuation coefficient to serve as the real-time reference price, as shown in the figure below:

    โ€‹ Decentralized deployment

    AI Oracle uses a decentralized oracle deployment, as shown in the following picture. The machine learning model calculates at AI Node, with data input provided by the Data sources node. Not the only one predictor node O is in the network, but n different predictor nodes (O1, O2,......, On). Each predictor Oi has its data sources that may not overlap. Oi takes and aggregates the data from the data sources and sends its own aggregated data Ai to request Req. BANKSY-SC will calculate A-Agg (A1, A2,...... using the number of Agg letters an) and return result A to USER-SC.

    Banksy-Oracle workflow

    1. User-SC initiates on-chain requests.
    2. Banksy-SC records events for Oracle.
    3. Banksy-AI-Node receives the event log and performs the task, request data from external API.
    4. Banksy-AI-Node processes the returned data and returns the processing result.
    5. Banksy-AI-Node core software sends data back to Banksy-SC.
    6. Banksy-SC aggregates the data into a single data and returns it to User-SC.

    Ecosystem Fitโ€‹

    The NFT trading platforms launched in the Polkadot ecosystem include NFTmart, Starry Network, DNFT, and Vera Defi. Only DNFT and Vera are involved in NFT lending, and they are all P2P models with many limitations.

    Banksy breaks through the P2P lending and supports users to directly mortgage NFTs in the platform pool, where Oracle conducts valuation and risk assessment and has a safety funds pool to guarantee their funds. The platform also supports users to liquidate their collateral that exceeds the threshold of the health factor. The entire solution balances the risks and benefits of the NFT mortgage pool and the safety funds pool to ensure the safety of funds.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • Tag line: An infrastructure for a blockchain-based decentralized cloud data network.
    • Brief description: Cumulus Encrypted Storage System (CESS) is dedicated to develop a new global decentralized cloud data storage platform โ€“ a blockchain-based network infrastructure that is transparent, efficient, and equal opportunity to all members of the global community. CESS encourages excess or under-utilized resources as nodes to join CESSโ€™s unrestricted expandable network via the token economy incentive method. Each node joins the CESS peer-to-peer network by contributing data storage resources, computational resources, or network bandwidth. Built on our state-of-the-art virtualization and cloud computing technologies, CESS organizes and manages the participating resources providing clients with secure, high performance, and boundless cloud data storage services. Furthermore, the CESS protocol enables interconnection of network nodes, to build a large decentralized cloud storage system that supports up to 100PB storage scale to meet the demand of enterprise level data storage. CESS will adopt a phased approach to implement the above goals.
    • Indication 1: With the goal of entering Polkadot ecosystem, CESS will build a blockchain system based on Substrate directly, and plans to develop custom pallets on FRAME. In the future, CESS will consider integrating to Polkadot in the form of Parachain to create a new decentralized cloud storage ecosystem, establish a large-scale distributed storage network.
    • Indication 2: With rapid advances of new computing technologies such as big data and machine learning, the value of humanityโ€™s digital assets, the so-called โ€œDigital Goldโ€, are being discovered. Explosively growing amount of data in cyberspace calls for new technologies of secure data storage and efficient data sharing. The challenges are to achieve secure storage, efficient sharing, and trading with data ownerโ€™s rights protection, but current solutions are complex and worrisome. Distributed storage networks can better drive the arrival of Web3.0 and are one of the underlying technical infrastructure of Web3.0.

    Project Detailsโ€‹

    We expect the teams to already have a solid idea about your project's expected final state. Therefore, we ask the teams to submit (where relevant):

    Mockups/designs of any UI components

    • Global nodes: Display the global map and the number of global nodes of distributed storage network, and mark the location distribution of nodes according to coordinates; Display node list.

    Image

    • My cloud disk: Personal storage space to view the files uploaded to the storage network; The list can be sorted by upload time, file name, file type and file size; Supports file download, share, property setting, deletion and other operations. Image

    • File upload: Select the files to be stored and set the relevant storage parameters.

    Image

    • Search for file: Search the whole network through keywords, and download the search results. Image

    Documentation of core components, protocols, architecture, etc. to be deployed

    • CESS is a high-speed, secure, scalable and decentralized cloud storage system. It can handle tens of thousands of transactions per second through parallel technology. Through Data slicing technology, it can achieve the secure storage of massive data, and it has the functions of Data confirmation and Data rights protection, which provides powerful data service ability. It provides DAPP with unlimited scalable storage capacity and perfect Data rights protection capability.

    • Data storage workflow: When a client requests to store a data file, the CESS platform pre-processes the data file to obtain and store its meta-data and data fingerprints. The pre-process software also performs data file replication and fault tolerant erasure coding. The meta-data includes info of data owner, data keywords, and etc. The data fingerprints are for subsequent data rights confirmation.

    • CESS client-platform interactions: A typical CESS data client and platform interaction flow is as follows: first, a data storage client interrogates CESS chain to get current storage price. The client then places an order for his/her data file via extrinsics on blockchain. Once the payment is made and order is approved, the client then uploads the data file using API provided by CESS platform. The data file is not directly uploaded to storage nodes, instead it is uploaded to a CESS storage scheduling node. The scheduling nodes are the ones with secure hardware environment (Trusted Execution Environment or TEE) and the data file will be pre-processed, encrypted, and sharded. Finally, the scheduling node distributes data segments to storage nodes to store. CESS storage miners do not make deal directly with clients, and they get rewarded from CESS system by providing storage space. Minersโ€™ storage resources are uniformly managed by CESS system, which fairly distributes data files. Miners have the responsibility to maintain the integrity of clientsโ€™ data. Any malicious behavior will be punished (CESS token deduction).
    • Overall system architecture: CESS adopts a layered and loosely coupled system architecture, which is divided into blockchain service layer, distributed storage resource layer, distributed content delivery layer and application layer.
    • CESS MDRC mechanism workflow: CESS have designed a unique Multi-format Data Rights Confirmation Mechanism (MDRC), which extracts data fingerprint from each data file to generate data certificate ID. By comparing similarities between data fingerprints, the system identifies data lineages of data files, and may take appropriate actions to prevent possible violations, and to provide strong evidences for ownersโ€™ data rights protection.

    Ecosystem Fitโ€‹

    CESS is a distributed cloud data network with user friendly ledgers, novel consensus mechanism, multiple data authenticity proof schemes, and reliable network infrastructure. CESS offers data storage service with the advantages of low cost, privacy protection, security and robustness. With the implementation of CESS data confirmation and proxy re-encryption technology, CESS provides Web3.0 clients and DAPPs with trustworthy, secure and reliable data rights protection.

    Compared to the similar projects in the Polkadot ecosystem including Ocean, DataHighway and Bluzelle, CESS storage service features:

    • Encrypted data storage
    • Multiple copies (3 copies by default, more upon request)
    • Sharded and distributed on multiple nodes
    • Highly scalable storage space
    • Transactions secured by CESS blockchain
    • Data rights protection for data owners
    • Competitive cost

    Documentation for Core Copmpontents

    Dispatcher

    The Dispatcher is a component of the omnichain smart contract infrastructure that receives commands/operations and dispatches them to the appropriate handler. The Dispatcher class enables developers to define command/operation handlers for the smart contract.

    Usageโ€‹

    The Dispatcher can be used in the implementation of the CQRS + Event Sourcing execution environment for Substrate framework. It receives commands/operations from external sources, such as a client or a node, and routes them to the appropriate command/operation handler.

    To use the Dispatcher, developers first define a set of command/operation handlers for the smart contract. These handlers can be implemented as methods in a Rust struct. The Dispatcher class then instantiates this struct and routes commands/operations to the appropriate method based on the type of command/operation.

    Benefitsโ€‹

    The Dispatcher provides a simple and flexible way to handle commands/operations in the smart contract. By defining a set of command/operation handlers, developers can easily add new functionality to the smart contract without having to modify the Dispatcher class itself.

    In addition, the Dispatcher enables developers to implement complex business logic in the smart contract by routing commands/operations to the appropriate handler. This allows for a more modular and maintainable codebase.

    Conclusionโ€‹

    The Dispatcher is a crucial component of the omnichain smart contract infrastructure. By enabling developers to define command/operation handlers for the smart contract, it provides a simple and flexible way to handle commands/operations. Its usage in the implementation of the CQRS + Event Sourcing execution environment for Substrate framework enables developers to implement complex business logic in a modular and maintainable codebase.

    EventStore

    Descriptionโ€‹

    The EventStore is a database that stores events in the order they occurred. It is a crucial component of the omnichain smart contract infrastructure support for Substrate framework. The EventStore class enables the storage of all events generated by the smart contract, allowing for a complete historical record of all transactions and changes to the smart contract's state.

    Implementationโ€‹

    The EventStore is implemented using an internal Substrate database. The EventStore stores events in the form of serialized binary data plus metadata, which can be easily deserialized for querying and analysis.

    Featuresโ€‹

    The EventStore includes the following features:

    • Event storage: The EventStore stores all events generated by the smart contract in the order they occurred, allowing for a complete historical record of all transactions and changes to the smart contract's state.

    • Querying: The EventStore allows for easy querying of events using various criteria, such as time range, event type, or specific parameters.

    • Deserialization: The EventStore can easily deserialize stored binary data for querying and analysis.

    • Scalability: The EventStore can handle large volumes of events and is designed for scalability.

    Benefitsโ€‹

    The EventStore provides several benefits to developers building smart contracts on the Substrate framework, including:

    • Transparency: The EventStore provides a complete historical record of all transactions and changes to the smart contract's state, ensuring transparency and accountability.

    • Auditability: The EventStore allows for easy querying and analysis of events, enabling developers to audit the smart contract's behavior and ensure compliance with regulations and business rules.

    • Flexibility: The EventStore can handle a wide range of event types and is designed for scalability, providing flexibility for developers building smart contracts on the Substrate framework.

    Conclusionโ€‹

    The EventStore is a crucial component of the omnichain smart contract infrastructure support for Substrate framework. It provides event storage, querying, deserialization, and scalability features, enabling developers to build transparent, auditable, and flexible smart contracts on the Substrate framework. The completion of this project will provide a powerful infrastructure for developers to build customized smart contracts on the Substrate framework, with the EventStore serving as a key component of this infrastructure.

    Snapshot Store

    Overviewโ€‹

    The Snapshot Store is a component of the omnichain smart contract infrastructure that provides a way to store and retrieve snapshots of the smart contract state. A snapshot is a read-only view of the smart contract state at a particular point in time. Snapshots are useful for optimizing the performance of the smart contract by reducing the amount of data that needs to be read from the event store.

    Implementationโ€‹

    The implementation of the Snapshot Store includes the following components:

    • Snapshot Store: The Snapshot Store is the primary component. It provides an interface for storing and retrieving snapshots of the smart contract state.
    • Snapshot Index: The Snapshot Index is a data structure that is used to index snapshots by their version. It allows for efficient retrieval of the latest snapshot.
    • Snapshot Writer: The Snapshot Writer is a component that is used to write snapshots to the Snapshot Store. It receives the current state of the smart contract and writes it to the Snapshot Store as a snapshot.
    • Snapshot Reader: The Snapshot Reader is a component that is used to read snapshots from the Snapshot Store. It receives a snapshot version and returns a read-only view of the smart contract state at that version.

    Conclusionโ€‹

    The Snapshot Store provides a way to store and retrieve snapshots of the smart contract state, which can be used to optimize the performance of the smart contract. The implementation includes the Snapshot Store, Snapshot Index, Snapshot Writer, and Snapshot Reader components. The completion of this component will provide a pefrormance optmization for omnichain smart contracts on the Substrate framework.

    Aggregate

    The Aggregate is a core component of the CQRS + Event Sourcing design pattern. It represents the current state of an entity and is responsible for handling commands and producing events.

    Descriptionโ€‹

    An Aggregate is a stateful object that represents a single entity in the system. It maintains its state by applying events to its internal state. A new state can be generated by applying new events to the existing state.

    In the context of the Substrate framework, an Aggregate is implemented as a Rust struct that contains its internal state and a set of methods to apply events and handle commands.

    Implementationโ€‹

    The Aggregate is implemented using the following components:

    Internal stateโ€‹

    The internal state of an Aggregate is represented as a Rust struct. The struct contains all the data necessary to represent the current state of the entity.

    Command handlingโ€‹

    The Aggregate contains a set of methods to handle commands. These methods accept a command object as input and return a set of events that represent the result of executing the command.

    Event sourcingโ€‹

    The Aggregate implements event sourcing by maintaining a list of events that have been applied to the internal state. When a new command is received, the Aggregate applies the appropriate events to generate a new state.

    Snapshottingโ€‹

    The Aggregate implements snapshotting by periodically storing a snapshot of its internal state. When an Aggregate is retrieved from its event stream, it can be initialized with the latest snapshot and then apply only the events that occurred after the snapshot.

    Conclusionโ€‹

    The Aggregate is a core component of the CQRS + Event Sourcing design pattern. It represents the current state of an entity and is responsible for handling commands and producing events. The implementation of the Aggregate in the Substrate framework provides a powerful mechanism for building complex and scalable smart contracts.

    AggregateState

    The AggregateState represents the state of an aggregate object in the event sourcing pattern. It is responsible for maintaining the current state of the aggregate object by processing the events that have occurred in the past.

    Propertiesโ€‹

    • id: The unique identifier of the aggregate object.
    • version: The version of the aggregate object.
    • events: The list of events that have occurred in the past.

    Methodsโ€‹

    • apply_event(event): Applies the given event to the current state of the aggregate object. This method updates the state of the aggregate object based on the event that occurred.
    • get_version(): Returns the version of the aggregate object.
    • get_events(): Returns the list of events that have occurred in the past.

    Usageโ€‹

    To use the AggregateState , you must first create an instance of it and initialize it with the current state of the aggregate object. You can then apply events to the aggregate object by calling the apply_event() method.

    Team's experienceโ€‹

    Our team's extensive experience in blockchain development and past successful projects make us well-suited for this project. We have developed several blockchain-based platforms, including DeSci, which offers a decentralized scientific communication infrastructure, and IPledger, which registers intellectual property assets on the blockchain. We have also built a Proof of Share protocol for verification on a chain that specific files have been shared between parties, an on-chain grants distribution platform, a decentralized technology transfer platform, F-NFT and Event Proxy for Substrate, and other projects.

    Our team members have also contributed to open-source blockchain projects, demonstrating our commitment to the development of the blockchain ecosystem as a whole.

    Our Team Lead is distributed systems architect and has over 14 years of experience in this field, with one of our team members being the inventor of omnichain smart-contracts protocol, which is an important aspect of this project. Our Software Engineer has over 10 years of experience in distributed systems engineering and was the ex-CTO at DEIP and the creator of the Economy Protocol. Our Tech Lead has experience in distributed system and blockchain R&D and was the ex-Head of R&D at Paralect, while also having experience as an ex-CPO at DEIP. Our Head of Marketing has 9 years of experience in PR and communications, having worked with micromobility and web3 startups. Our Product Manager expert in digital transformation has 6 years of experience in the procurement of 50+ leading private and state Ukrainian enterprises.

    As a team, we have previously applied for a grant from the web3 foundation grants program for our DEIP project (DEIPWORLC Inc. legal entity). However, due to the constantly evolving market landscape and changing needs of the industry, we decided to pivot multiple times, and therefore did not deliver original proposal fully (only about 50% of it - onchain part). During the process we realized that on-chain IP management would not be possible without other infrastructure part. Therefore we decided to completely stop previous project, change our focus and start working on a diferent solution, the core solution that will make possible to implement DEIP and other our projects that rely on omni-chain infrastructure and onchain IP management - omni-chain infrastructure

    We believe that being transparent about our previous application and pivot is important. We want to assure the committee that we are committed to delivering the proposed solution for our current application, and that we are passionate about creating value in the blockchain ecosystem.

    We are confident that our team's expertise and experience in developing distributed systems and infrastructure will enable us to successfully execute our proposed CILA omnichain infrastructure project. We believe that this infrastructure is crucial for the growth and adoption of blockchain technology, and we are excited about the opportunity to contribute to this space.

The testing guide will contain instructions on how to execute these tests.
    0d.DockerWe will deliver Dockerfiles for testing all the functionality included in this milestone.
    1.Substrate module: AggregateThe Aggregate pallet provides the base functionality for implementing the Command Query Responsibility Segregation (CQRS) pattern on a Substrate-based blockchain. It defines the Aggregate trait, which is used to define the state and behavior of an Aggregate.
    2.Substrate module: AggregateStateThe AggregateState pallet provides a default implementation of the AggregateState trait, which stores the current state of an Aggregate in the blockchain's storage. This pallet is responsible for managing the state of an Aggregate and updating it based on incoming commands.
    3.Substrate module: AggregateRepositoryThe AggregateRepository pallet provides an implementation of the AggregateRepository trait, which is responsible for retrieving and storing Aggregates in the blockchain's storage. It allows developers to easily store and retrieve Aggregates from the blockchain's storage.
    4.Substrate module: CommandDispatcherThe CommandDispatcher pallet provides a way to dispatch incoming commands to the appropriate Aggregates based on their type. It uses a HashMap to store the mapping between command types and the Aggregates that handle them.
    5.Substrate module: EventStoreThe EventStore pallet provides a way to store and retrieve events that have been emitted by Aggregates. It allows developers to easily retrieve the events emitted by a specific Aggregate and replay them to reconstruct the current state of the Aggregate.
    6.Substrate module: EventsEmitterThe EventsEmitter pallet provides a way for Aggregates to emit events. It defines a trait that Aggregates can implement to specify the types of events they emit, and provides a way to subscribe to events emitted by specific Aggregates.

    Milestone 2 โ€” Testing and Documentationโ€‹

    • Estimated duration: 1 month
    • FTE: 2
    • Costs: 10,000 USD
    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will ensure comprehensive documentation of the code by providing both inline comments and a step-by-step tutorial. This tutorial will guide the user through spinning up a Substrate-based execution environment for the CILA Omnichain Infrastructure and testing omnichain transactions, showcasing the new functionality. Special attention will be given to documenting the setup and testing of multiple Substrate chains running simultaneously, to test the synchronization of the state smart contract between them.
    0c.Testing and Testing GuideWe will conduct comprehensive unit testing on the core functionalities including Aggregate, Event Store, Aggregate Repository, Snapshot Store, and Dispatcher, to ensure optimum functionality and robustness. In particular, we will place emphasis on testing the infrastructure running with multiple chains to ensure that the synchronization mechanism is functioning as intended. The testing guide will contain instructions on how to execute these tests.
    0d.DockerWe will deliver Dockerfiles for testing all the functionality included in this milestone, including orchestration with multiple chains. For orchestration purposes we might use Kubernates.
    0e.ArticleWe will publish a technical article that details the implementation of the Command-Query Responsibility Segregation (CQRS) and Event Sourcing architecture on the Substrate framework. The article will provide an in-depth explanation of the design choices made and the challenges faced during the implementation. It will also include a detailed walkthrough of the codebase, highlighting key areas of interest and how they fit into the overall architecture. The article will be written in a technical language that targets developers with experience in blockchain and distributed systems.
    1.Substrate chainSet up and run multiple Substrate chains simultaneously to test the synchronization of a state smart contract between them. This will involve deploying the omnichain smart contract infrastructure to each chain and executing transactions on each chain to ensure that the contract state is properly synchronized between them. Additionally, various network conditions such as network latency and node failures will be simulated to test the robustness and reliability of the synchronization mechanism. The results of these tests will be recorded and analyzed to identify any potential issues and ensure that the synchronization mechanism is functioning as intended.
    2.Automated TestsWe will create and publish automated tests for critical infrastructure parts of Substrate-based CQRS + Event Sourcing execution enviroment. The aim of this test will be to test two cases - non conflicting execution (changes coming to one chain and transmitted to the other one), and conflicting transactions when the same aggregate is updated with two conflicing state changes that simuntaniusly come to different chans.

    Milestone 3 โ€” Example Smart Contracts and Enhancementsโ€‹

Additionally, comprehensive unit tests will be developed and documented to ensure the functionality and robustness of the NFTAggregate pallet and NFTAggregateState pallet. A testing guide will also be provided, describing how to run the tests.
    0c.Testing and Testing GuideFor this milestone, we will develop comprehensive unit tests to cover the core functions of the NFTAggregate module and the NFTAggregateState pallet. These tests will be designed to ensure the functionality and robustness of the code. The unit tests will be included in the code repository and will cover a range of scenarios to ensure that the code is thoroughly tested. For example, we will test the minting, burning, and transferring of NFTs, as well as error handling and edge cases. In the testing guide, we will provide detailed instructions on how to run these tests, including any required dependencies and setup steps. We will also include information on how to interpret the test results and what to do in the case of failures or errors..
    0d.DockerIn order to facilitate testing and deployment of the NFTAggregate pallet and NFTAggregateState pallet, we will provide Dockerfiles that can be used to easily set up and configure a development environment. These Dockerfiles will include all the necessary dependencies and configuration to run the Substrate-based blockchain with the new functionalities.
    1.Substrate module: NFTAggregateThe NFTAggregate pallet provides a way to implement Non-Fungible Tokens (NFTs) on a Substrate-based blockchain. It defines a trait that NFT Aggregates can implement to specify the behavior of NFTs, including minting, burning, and transferring.
    2.Substrate module: NFTAggregateStateThe NFTAggregateState pallet provides a default implementation of the state of an NFT Aggregate, which stores the current state of NFTs in the blockchain's storage. This pallet is responsible for managing the state of NFTs and updating it based on incoming commands.
    3.Report: Substrate Ecosystem NFT standardsTo choose the most optimal standard for omnichain implementation we will conduct research and assess all the available NFT standards against two major criteria: popularity and technical quality. Popularity will be measured by the number of stars on the GitHub repository and how many projects are actually using it (usage assesment will be done on a best effort basis), and the technical quality will be assessed by analyzing if a specific standard satisfies SOLID design principles.

    Future Plansโ€‹

    In the short term, we plan to continue to develop and enhance our project to ensure its success and sustainability. This will include ongoing testing, bug fixes, and implementing additional features and improvements as needed. We will actively promote our project through various channels, including social media, blog posts, and community events.

    After the completion of the proposed infrastructure, we intend to continue its development by incorporating support for multiple blockchains and introducing more advanced functionalities, such as dynamic rebalancing for aggregates. Additionally, we plan to establish partnerships with leading players in the Substrate/Polkadot/Kusama ecosystem and to integrate our omnichain infrastructure with existing projects, such as DeFi and NFT marketplaces, to further increase adoption. Finally, we will provide comprehensive documentation and support to ensure that our infrastructure is accessible and user-friendly for developers and users alike.

    In the long term, we envision our project becoming a leading platform for event-centric CQRS + Event Sourcing execution environments and omnichain smart contracts on the Substrate blockchain. We plan to expand our team and further invest in research and development to stay ahead of the curve and meet the needs of the rapidly evolving blockchain industry. We will continue to engage with the community and seek feedback to ensure that our project remains relevant and valuable to users. Our ultimate goal is to create a platform that is widely adopted and helps to drive the mainstream adoption of blockchain technology.

    Based on the positive feedback we would like to push the project further and bring more valuable features for the users, closely cooperating with the Subsquid team and gathering an ongoing feedback from the users.

    While developing Calamar, we focus on UI and UX friendliness so that users enjoy dotsama chains exploring, as well as relevance of displayed data.

    Project Detailsโ€‹

    Calamar explorer will allow users to search and display various items and statistics.

    The plan is to have at least these features implemented:

    Homepageโ€‹

    Homepage with google-like search box and with links to chain dashboards.

    Home page

    Search where you don't have to know which chain the searched item belongs to. You just put the hash into the search box and the explorer will take care of the determining on which chain it is. This is going to be an addition to the ability to restrict search to a specific chain.

    Block detailโ€‹

    Display block's data and its extrinsics, transfers, calls and events.

    Extrinsic detailโ€‹

    Display extrinsic's data, its calls and events.

    Call detailโ€‹

    Display call's data, and its events.

    Event detailโ€‹

    Display event's data

    Search extrinsics and events by nameโ€‹

    Display a list of matching extrinsics and events by name.

    Account detailโ€‹

    As we are gathering feedback, one of the most important features for the users seems to be the account overview where users can find information about their balances and transactions across all chains.

    Account page

    Chain dashboardsโ€‹

    Each chain will have own dashboard with statistics and listing of latest blocks, latest transfers, top holders, etc. It makes the explorer more useful even for users who are not searching for specific items.

    Metadata explorerโ€‹

    The runtime metadata of each chain are still evolving and changing but it is not so easy to display them in a structured and human-readable way. There is e.g. a tool https://wiki.polkadot.network/docs/metadata which displays them but only latest version and supports only a few networks. The metadata explorer we are going to implement will support all the networks and also historical versions of the runtime spec.

    Metadata explorer

    Item metadataโ€‹

    The metadata information will be deeply integrated into whole Calamar so we can display it in the detail pages of the items. E.g. in extrinsic's detail page we will show info for the call name, error, parameters and link to the metadata explorer for more info.

    Extrinsic metadata

    Search input autocomplete for call and event namesโ€‹

    Thanks to the metadata we can also autocomplete and suggest the call and event names when typing into the search input.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 โ€” Core functionalityโ€‹

    Even though we have the already working application, there are still many things missing. Some of them prevent the users from using Calamar fully as the main explorer. We need to first assure the correct core functionality, display all the meaningful data which are retrievable without further complex processing, improve design and UX and integrate more into the Polkadot ecosystem.

    Milestone 2 - Account detail & Chain dashboardsโ€‹

    In this milestone we are going to improve account detail page and replace latest extrinsics page with proper dashboard page for each chain.

    Subsquid (data provider) might not support each feature for all chains at the time of the implementation, so the features will be implemented universally to support each chain whenever the data are provided in the future.

    Future Plansโ€‹

    There is a huge potential for future improvements which the Polkadot's community can benefit from.

    We would like to definitely display information about XCM transfers and teleports.

    As developers of most parachains implement their own custom modules/pallets it opens the opportunity to cooperate and customize Calamar explorer with UI/UX components and logic tailored to their needs.

    It relates to various XCM transactions which makes it even more complex and the more types will our explorer support the more it makes the users' lives easier.

    Turn-key Private Standalone Blockchain Network

    • Proposer: Cere-Network
    • Payment Address: 1BbyAGddobdPgNo9c63xsRnwK5hen8pV7F

    Project Description ๐Ÿ“„โ€‹

    Cere Network is providing a turn-key Private/Permissioned/Standalone blockchain network which can be readily integrated by any enterprise. Since itโ€™s built with Substrate, this network can be integrated into any Polkadot/Substrate based Layer 1 network to serve as a secondary chain.

    This turn-key network intends to abstract the implementation complexity for businesses, as well as providing a ready-made package to optimize for a higher level of security, privacy, and performance, and to serve as a template or base-implementation of a highly customizable and performant enterprise specific blockchain network.

    Furthermore, any network built from or derived from this project will also be able to use derivative assets to represent real-world value transfers on-chain (e.g. micropayments, discount vouchers, loyalty points, etc), as well as being able to programatically issue these assets between user and application wallets.

    Below we have the overview of all the key features that this project will support:

    • A set of turn-key substrate based packaging and tools that simplifies the customization, configuration, testing, and deployment of such a blockchain network.
    • Pre-built solutions to create/assign/transfer derivative assets in business to consumer use cases.
    • Pre-configured and optimized for feeless transactions and performance.
    • Creation of custom derivative assets and automate the transfer to/from user wallets to app wallets by any/app brand.
    • Optimization of batch user onboarding and transaction processing for higher throughput situations needed for consumer apps/sites.

    There will be three primary directories in this repository:

    Node: A blockchain node is an application that allows users to participate in a blockchain network. Substrate-based blockchain nodes expose a number of capabilities like, Networking, Consensus, RPC Server.

    Runtime: The terms "runtime" and "state transition function" are analogous - they refer to the core logic of the blockchain that is responsible for validating blocks and executing the state changes they define. The Substrate project in this repository uses the FRAME framework to construct a blockchain runtime. FRAME allows runtime developers to declare domain-specific logic in modules called "pallets".

    Pallets: The runtime in this project is constructed using many FRAME pallets that ship with the core Substrate repository and a template pallet that is defined in the pallets directory. A FRAME pallet consists of a number of blockchain primitives namely, Storage, Dispatchables, Events, Errors and Trait.

    NumberDeliverableSpecification
    1.Documentation and basic testsWe will provide README files inside repositories with instructions of how to build, deploy and test.
    2.Ink! based Smart Contract StandardWe are introducing a new smart contract standard which allows assets adaptable for real businesses to be programmatically created, managed, owned, transferred, and traded. It provides a template for establishing a foundation to capture common enterprise utility, and can be easily extended.. This standard is purposefully being built on top of Parityโ€™s ink! Smart contract framework.
    2a.Enterprise Derivative AssetsDerivative Asset support for the enterprise needs, with attributes such as expiration, limit on transfers, longitudinal unlocking, redemptions, etc
    2b.Manual Direct Wallet TransferSupport for most Substrate/Polkadot based wallet applications. Smart Contract transfer function allows for the directly wallet-signed transfer of assets from one application/user address to the other.
    2c.Programmatic Asset TransferSmart Contract transfer function allows for the programmatic/automated transfer of tokens from one application/user via smart contract to the other.
    2d.Asset RestrictionsSupport for the locking of assets by time or by issuer permission, support for expirations and potentially invalidations.
    3.Smart Contract TestsThe Smart Contract implementation will include unit tests, we will be using the off-chain test environment that ink! provides.

    Coinversation Protocol

    Project Overview ๐Ÿ“„โ€‹

    Coinversation Protocol is an open financial platform integrating stablecoin, synthetic asset issuance, collateral lending, decentralized contract exchange and Polkadot bridge. Coinversation Stablecoin is a very important part of it. Coinversation is committed to making breakthrough contributions to the stablecoin and DeFi in the Polkadot ecosystem.

    Overviewโ€‹

    The stablecoin created by Coinversation Protocol is decentralized, multi-asset collateralized, supports cross-chain, and supports real-world asset access through Polkadot bridge. The biggest difference between it and the past decentralized stablecoins is that there are no stability fees or interest, but stablecoins are issued in a synthetic asset collateral pool. Therefore, the cost that users pay to generate Coinversation Stablecoin (cUSD) through collateral is determined by the relative change of all synthetic assets in the entire system, rather than artificial regulations in previous decentralized stablecoins (e.g. Dai). This cost is more market-oriented, and at the same time it is equivalent to the inflation rate of stablecoin to world assets. In general, the stable currency cUSD and the synthetic asset issuance and contract exchanges in the Coinversation Protocol constitute a complete Defi system in the Polkadot ecosystem. In addition, we can access alliance chains such as AntChain and HyperChain through Coinversation's own bridge to realize access to various real-world assets. This will not only enrich the collateral for this project, but also enrich the range of assets in the entire Polkadot ecosystem through cross-chain.

    Project Detailsโ€‹

    The main functional modules of the entire system include: Polkadot bridge, forging synthetic assets(MintC), DEX, collateral pools, fee pools, oracles, and liquidity mining.

    Coinversation architecture diagram

    Polkadot Bridgeโ€‹

    This bridge connect several alliance chains, such as AntChian and HyperChain, into Coinversation Protocol and Polkadot ecosystem. So assets on those chains can be used as collateral to issue stablecoin and synthetic assets. Meanwhile, Coinversation Stablecoin can also provide liquidity for those assets through cUSD lending.

    Forging Synthetic Assets(MintC)โ€‹

    The synthetic assets issued by the entire system are all produced by users staking certain collateral. The initial collateral includes CTO and DOT, and the collateralization ratio is 800% and 500% respectively. In the future, the collateral and collateralization ratio can be adjusted through community governance. When users stake collaterals and forge synthetic assets, corresponding debts are generated. When the user wants to unlock the collateral, he must repay the debt, that is, destroy the previously generated synthetic assets.

    cUSDโ€‹

    At present, it is stipulated that the assets synthesized by direct staking of collateral are the stablecoin cUSD. That is, after users stake the CTO or DOT, the directly generated synthetic asset is cUSD, while other synthetic assets need to be converted by the user through contract trading in DEX. The price of cUSD is always defined as $1 throughout the system. All cUSD generated by all users is the total liability of the entire system, priced in cUSD.

    Through contract trading, cUSD can be converted into any synthetic assets supported by the system, such as cBTC, cETH, and even cAAPL, cXAU linked to traditional assets such as stocks and gold, and supports long or short. The types of synthetic assets can be added by community governance. It should be noted that if the user simply holds cUSD after minting, it is equivalent to automatically shorting all other assets in the system.

    DEXโ€‹

    It is an exchange that provides conversion of different synthetic assets and contract trading. Due to the design characteristics of CP, this DEX does not require a counterparty, and there is no issue of transaction depth.

    Collateral Poolโ€‹

    The collateral pool is the sum of synthetic assets generated by all users, and is priced in cUSD. According to the amounts of synthetic assets generated by each user, the debt pool also records the proportion of each user's debt. Whenever a new synthetic asset is generated, the debt ratio of the system must be recalculated.

    Fee Poolโ€‹

    Users trading or converting synthetic assets on the DEX will incur transaction fees. The fee ratio is tentatively set at 0.3%, and these fees all enter the fee pool. The fee is collected in cUSD, and all the fees are distributed to users in proportion to the debt. The system stipulates that only users whose collateral is the CTO can receive rewards, as an incentive for CTO holders. Because the CTO price fluctuates, it is stipulated that only users who meet the collateralization ratio are eligible to receive rewards.

    Oracleโ€‹

    Since the price of contract trading needs to be read from outside sources, the oracle is a very critical part of this project. In the initial stage, the system will use the centralized oracles provided by the project team, and in the future, it will introduce more secure decentralized oracles.

    Liquidity Miningโ€‹

    Liquidity mining is the module of issuing CTO tokens. Users can lock CTO or DOT here to get the rewards of CTO. The proportion of rewards obtained by CTO and DOT is different. It also stipulates that users who lock their tokens for liquidity mining must also put a corresponding proportion of CTO or DOT in the collateral pool to mint synthetic assets, to provide more liquidity for the entire system.

    At present, the type of synthetic assets of the project is determined by the project team or community governance. In the future, it is planned to upgrade so that different investors can independently sign any type of contract on this system.

    At present, the stablecoin cUSD or other synthetic assets produced by the project are limited to the system. When there are standardized tokens similar to Ethereum ERC-20 on the Polkadot in the future, all synthetic assets of this project can be circulated outside the system in the form of standardized tokens, and even enter other exchanges. Among them, cUSD can become an important stable currency in the Polkadot ecology.

    Overviewโ€‹

    Decentralized, on-chain bridge attestation oracle for Polkadot using off-chain workers

    Over the last few years, bridges have been the target of a number of high profile hacks. According to the rekt.news 'hack leaderboard', 4 of the top 5 hacks in terms of USD value lost were attacks on bridges (total $2.2 billion lost amongst these 4 hacks). Despite many efforts to develop more robust and secure bridge architectures, there is no industry-wide tooling available for protocols to bolster their security in case a bridge is hacked. This is why we aim to to develop a decentralised, real-time bridge status update oracle that will help protocols in the Polkadot ecosystem protect their operations and customer funds.

    Bridge Attestaion Oracle Solution Overview

    Our approach is to introduce on-chain verification of bridge balances on the Polkadot network using off-chain workers. The main idea behind this is that all dapps operating on Polkadot parachains will be able to integrate this security module, enabling them to trigger automated precautionary notifications and actions in case bridge balances unexpectedly drop. We achieve this by tracking bridges' locked asset vs issued assets across multiple chains. This allows us to calculate a collateral ratio, which protocols can use to define and trigger safety procedures in their code when the specified conditions are met.

    The DIA team has already gained experience with collateral ratios, while creating fair value price feeds for Liquid Staked Tokens in the Polkadot ecosystem and beyond (more info here). The bridge attestation oracle would be specifically designed for use in the Polkadot ecosystem. Being a crosschain oracle by nature, we perceive a significant benefit in the proposed solution, because using the collateral ratio in the determination of asset prices that use bridges to bring liquidity to multiple blockchains enables the calculation of fair value prices.

    Project Detailsโ€‹

    Architecture overviewโ€‹

    The proposed project consists of a few core components that are to be developed.

    First, an overview regarding the data structures needed to represent bridge states:

    Asset:
        Address  string
        Chain    string
        Decimals uint
        Symbol   string
        Name     string
        
    BridgeSet:
        LockedAssets  []Asset
        MintedAsset   Asset
        LockedAmounts []uint
        MintedAmount  uint

    Bridge:
        Sets []BridgeSet

    Note that BridgeSet is directional, so a bridge can hold a set twice in both directions if needed. By that, we can track minted and locked pairs in an omnidirectional way. Also note, that a BridgeSet mints one token but can access several locked assets on different source chains.

    With these in mind, the following components are proposed:

    1. An off-chain worker which reads bridge states: This component is used as an adapter between bridge states and the target parachain. It is used to read the amounts of locked assets from specified addresses (the bridge reserve addresses).
    2. A token identification system which identifies matching tokens across multiple chains (i.e. both sides of each bridged asset). Identification requires that for an asset at least the chain and the address are defined.

    An example flow on the token identification within the proposed system could look like this:

    1. Read bridge-locked tokens on multiple source blockchains with RPC calls.
    2. Compute total amount of locked tokens by adding the values from the previous calls.
    3. Determine the amount of issued tokens on the target network.
    4. Perform calculation MintedAmount - Sum([]LockedAmounts).
    5. Output values of number of issued tokens, number of locked tokens and collateral ratio values.

    All components will be available open-source to enable access to any dapp/protocol that intends to integrate this or further develop the components. Also, a standard format (similar to the defined data structures above) will be developed to facilitate integrations of future bridges.

    Technology stackโ€‹

    • Pallet & off-chain workers will be the main enabler of the entire solution, reflecting Polkadot's native feature of off-chain workers integrated with pallets.
      • Rust programming language will be used to develop the pallet and the off-chain worker.
    • RPCs will be the main gateway for querying data from different chains. As RPCs represent single points of failure, they will be implemented using the following logic:
      • Only publicly available RPCs will be used to circumvent private key management hurdles for publicly accessible solutions. If technically possible, we would enable the pallet integrator to choose their own private RPCs, if they prefer this.
      • We will set-up a back-up system of at least 2 additional public RPCs in case one RPCs fails.
      • We will set-up backstops for generating collateral value in case at least one of the RPCs fail.

    Hosting and infrastructure will be organized as follows:

    The main repository will be available on Github. Pre-built instances of our container images will live in Docker Hub for everyone to download. We seek to implement a CI/CD system that automatically builds and publishes latest changes so that anyone can use the latest version with ease and integrate fetching the latest version in their automation flow as well. Due to the decentralized nature of the proposed architecture, only the token identification data needs to be hosted centrally. For that, we will either extend existing community directories or build our own, with hosting the resulting identification files on github as well.

    We will also host documentation on how to use and participate in the system.

    MVPโ€‹

    Our MVP will consist of four main parts:

    1. The pallet providing collateral value that can be integrated by parachains
    2. The documentation of integration
    3. Integration of 2 bridges
    4. Guidelines on integrating new bridges

    Expectationsโ€‹

    Team DIA will:

    • Create the framework and open-source the library of this integration.
    • Integrate 2 bridges for initial use. Further integrations will be open for submissions from contributors.

    We will not:

    • Cover a security audit as a part of MVP design.

    Ecosystem Fit (Requirements)โ€‹

    Overviewโ€‹

    The Polkadot ecosystem is a natural fit for this solution for several reasons:

    • Polkadot is a network of numerous parachains which utilize XCM for trustless and secure communication without relying on bridges. However, to achieve the vision of interoperability with external chains, bridge monitoring and attestation are necessary to establish trust and ensure the integrity of the transactions between the networks.
    • The entire architecture of the product is tailored specifically to the Polkadot ecosystem due to it's unique ability of executing computational programs via off-chain workers.
    • The tool adds significant value for a variety of Polkadot ecosystem actors - parachains, dapps, bridges, oracles and others.
    • The tool aims to serve as a public good on Polkadot, therefore will benefit anyone that integrates it.

    Target audienceโ€‹

    We have identified our target audience as follows:

    • Parachains are the target facilitator that will enable the adoption, but they also stand to benefit from integration themselves as the tool enables them to track bridges' security on a chain level.
    • DeFi dapp developers (e.g., lending protocols) are the main beneficiaries. We expect to see most adoption from them, as they are the arbiters that enable bridged assets to be traded/staked or used however else and thus are most directly exposing their users' assets to these risks.
    • Bridges can integrate the security module to create their own security processes. They will strongly benefit from having an independent third party tracker next to their own internal ones.
    • Oracles will be able to use the collateral ratio for interchain asset pricing. In theory, native asset trading statistics can be bridged to synthetic asset in order to decrease manipulation risk.
    • As the module will be fully open source, any other Polkadot ecosystem developer/team can integrate it for their use cases.

    Meeting the needsโ€‹

    Bridge hacks are rare but painful because of the potentially high amount of funds that are constantly at risk / an attractive target for malicious actors. Therefore, the bridge attestation oracle will provide a live auditing tool for any actor in the Polkadot ecosystem that wants to make their operation more secure.

    In discussions with various ecosystem actors, the idea and architecture of the solution were presented with the goal of validating the problem and the potential solution. We received supportive feedback from all interviewees, and therefore decided to pursue the inititive further.

    To verify the relevance of the idea we conducted interviews with several ecosystem participants, including

    • Acala
    • Astar
    • AstridDAO
    • Interlay
    • Pendulum
    • StellaSwap

    Similar projectsโ€‹

    We were not able to identify any similar solution present in the market. Similar approaches can be attributed to:

    1. Proof of Reserves oracles - developed by several oracle providers, these oracles track the amount of tokens in reserves and provide this information publicly.
    2. Cross-chain messaging protocols - these have architectural similarity in that one could transmit bridge balances as a message, however there are several limitations to this approach:
    • They would act as a 2nd layer bridge (bridge for bridge balances) and are also prone to manipulation.
    • Gas fees would have to be paid on the origin chain, which causes potentially volatile costs required to run such operation, putting them at risk.
    1. Real time alert providers for smart contract activities. Tools such as Forta allow to set-up monitoring and notifications for pre-determined smart contract activities. However, they do not offer a direct solution for bridge balance monitoring, which we aim to deliver.

    As our proposed solution is different in nature, we do not perceive any of the existing approaches as real alternatives. Additionally, all of these solutions are commercially driven, while the bridge attestation oracle will serve as a public good.

    Risksโ€‹

    • RPC manipulation risk - the solution will use RPC services to retrieve data from blockchains. Therefore, if someone manages to manipulate RPC data, the final value could be exploited. A potential mitigation could be to introduce connections to multiple RPCs simultaneously to reach a consensus.
    • Contract migration risk - from time to time protocols may need to migrate or upgrade contracts. This could produce incosistent values. To avoid this, direct communication channels with bridges can be set up and tracked to flag any changes on the smart contract level. This could be complemented with community based forum where contributors could also flag these migrations manually.
    • Off-chain worker operational risk - the solution is developed on the assumption that off-chain workers can be trusted and will be maintained within the Polkadot ecosystem. However, upgrades, malfunctions or the unlikely event of discontinuation of off-chain workers poses a risk to the solution. In this case, migration to another off-chain computation platform could be a mitigation (e.g. Phala or Integritee).

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    DINFRA, decentralized infrastructure, is substrate orchestrated infrastructure, a decentralized alternative to public clouds.

    Substrate allows us to create a specialized blockchain, which we see as the perfect blending between Custom Functionality, Decentralized Governance and Value/State tracking.

    Modern data-center technology is now software defined, API driven and hyper-convergent with capability to virtualize Compute, Storage and Networking. Specialized network equipment is being replaced by virtualized services. There is also great availability of Open Source technologies covering all aspects of the modern data center.

    DINFRA aims to create a Substrate blockchain to orchestrate hyperconvergence infrastructure in a democratic, decentralized, open/neutral and non technically opinionated way.

    Realizing DINFRA vision requires a viable strategy. This project represents the first phase of a three phase strategy in which an Open Source Minimum Viable Product is delivered for the purpose of developing, testing, generating awareness and gaining community support.

    After delivering Polkawatch, our analytic engine to measure decentralization of the substrate validation process, DINFRA is the natural next step for us to take in the Substrate Ecosystem. We have a track record contributing to Cloud automation stacks, we created Privazio for small organizations to be able to fully automate their infrastructure and have used it to deliver Polkawatch for Polkadot and Kusama. We would like to start contributing to effective substrate infrastructure decentralization next.

    For a complete presentation of DINFRA vision and strategy see this Video Presentation.

    Project Detailsโ€‹

    Design Constraints

    We gave been part of the Dotsama community and that has allowed us to gain a better understanding of how it operates. Consequently, some key decisions have been taken that impact our choices of design and architecture:

    • DINFRA must be open and non technically opinionated. Infrastructure providers must be able to offer their solutions via DINFRA without being forced into specific technologies or opinionated solutions. Furthermore, they should be able to offer their current infrastructure via DINFRA provided they have industry standard automation capabilities, which typically they do, with minimal effort.
    • DINFRA must be decentralized and democratic adopting and following the practices that we see on Kusama and Polkadot for governance.
    • DINFRA must focus on the needs of our ecosystem first.

    We consider these points a prerequisite for community acceptance and adoption.

    Design Interfaces and Data Modeling

    DINFRA main responsibility will be to mediate between consumers and providers awarding "deployment descriptors" to "infrastructure providers" by means of consensus, collect balances accordingly, etc.

    From the previous constraints we deduce that we need lose typing of deployments descriptors, and DINFRA being able to distribute descriptors as opaque entities which don't need to be fully understood.

    Infrastructure Providers should be able to self register on DINFRA with information about which types of descriptors they can serve, even register new types of Deployment Descriptors for their flavored solutions if they happen to have some differential in-house capability.

    Deployment Descriptors will be able to represent things as diverse as a Helm Chart, Docker Compose, Cloud-Init user data, Subquery Project descriptor or IPFS cluster member profile. As long as each Provider registers their deployment capabilities properly, DINFRA must be able to route deployment requests to them.

    Deployment descriptors will be specified in JSON with its type defined as a JSON Schema. This provides loose typing and flexibility to accommodate any deployment descriptor possible, besides the fact that JSON/YAML is a widely used already by most infrastructure platforms and solutions.

    Note that Deployment descriptors won't be stored on chain but preimaged and backed on IPFS, as they are required during deployment. Secrets, whenever possible should be deduced from on-chain data preferably in the form of public keys.

    High Level Architecture

    DINFRA Architectural stack resembles pretty much a substrate stack under an infrastructure automation stack, like this:

    DinfraHLArch

    We make the active choice of not connecting infrastructure platform / automation stack directly to the blockchain, for example via its Offchain Worker Interface, but we introduce an intermediate component called "Chain Reactor."

    The Chain Reactor is responsible for orchestrating infrastructure according to decisions taken on chain. The most prominent actions would be to deploy infrastructure as a descriptor is awarded or tear down infrastructure as a deployment reaches its termination.

    In order to fulfill the constraints above, Chain Reactors must be easy to implement using any infrastructure automation stack on any suitable language, and it must be simple to do so. Whether Python/Ansible, Java/Cloustack, Go/Terraform, Go/Helm, Python/Juju, etc. Chain Reactors must rely on programming language-agnostic API specifications/tooling such as OpenAPI/swagger for generating stubs in any language that can be used as base for implementation.

    Technology Stack Used

    In line with the strategy decided above, this project will focus on a minimal viable product while honoring the constraints and architecture above.

    The components generated must also serve as "Reference Implementation" to community members willing to generate similar implementations for other infrastructure platforms or solutions.

    The Stack for the current MVP will be made of:

    • Apache CloudStack: As Infrastructure Platform
    • Ansible / Python: As tooling for implementing a Chain Reactor.
    • Substrate: For DINFRA Parachain
    • Gitlab CD/CI: For Reference Implementation of Automated Testing and CI/CD.
    • Docker Compose: For rapid development setup.
    • Gitlab CD/CI: for End to end Itegration testing, to avoid regression when new Apache CloudStack versions are released.

    Scope

    Lots of the features that we pitch in our DINFRA video presentation are left out of the scope of this phase. DINFRA opens a lot of exciting possibilities but it is important to remain in focus and deliver a MVP useful for development and bringing community awareness now.

    What DINFRA is not

    DINFRA is not an Infrastructure Provider for the Dotsama ecosystem, but rather a parachain designed to arrange deployments between infrastructure consumers an infrastructure providers in a decentralized way.

    DINFRA may provide concrete infrastructure automation modules, but they will be open-source and infrastructure providers will be able to use them, modify them or utilize as reference implementation for their own.

    DINFRA is not meant to deliver a company or venture but rather a decentralized community that follows Polkadot's governance model and serve our ecosystem first.

    DINFRA will not become a way to just "open" infrastructure to the whole world. Blockchain features may be used for consumers to pick specific providers, providers to accept specific consumers even for consumers to manage their own infrastructure in a private way. Completely public infrastructure remains a valid use case but would benefit from on-chain features such as reputation, arbitrage, deposits, offenses, etc for it to be practically viable.

    Ecosystem Fitโ€‹

    As we can see with Polkawatch, our infrastucture plays an important role in the level of effective decentralization of Substrate Validation process.

    Our treasuries invest significant funds on infrastructure, for which our ecosystem counts with fantastic providers. However, it is becoming clear that our ecosystem needs strategic actions at infrastructure level. Some projects have already been started by our treasuries, a good example being the Infrastructure Builders Program.

    DINFRA intents to provide an strategic approach to managing our ecosystem infrastructure using our biggest asset: Substrate itself.

    On the other hand our ecosystem is investing significant effort on Decentralized Finance. A successful DINFRA parachain, used to arrange delivery of our own infrastructure, would channel significant resources becoming effectively a Web3 commodity: a currency that everybody in our community needs and uses, backed by real, tangible, infrastructure services. This would provide health to our DEFI community as DEFI is often criticized for baking tokens with tokens non of which are backed by "real" assets. Commodities play an important role in traditional economies and the same could apply to our ecosystem.

    The target audience of DINFRA is therefore our Governance bodies, infrastructure providers, infrastructure consumers (Parachains, DAPPs, etc), and on the other hand substrate, UI and infrastructure engineers willing to contribute.

    Regarding similar projects, on top of strategic programs launched by our treasuries there is also ThreeFold. An impressive decentralized infrastructure venture which utilities substrate technology while not being formally part of our ecosystem. We had the pleasure to meet their friendly team during the last Sub0 conference in Portugal and their experience was instrumental in realizing that DINFRA is far from a technological-only challenge and needed key design constraints for it to be acceptable to our ecosystem: inclusive to current infrastructure providers, non technically opinionated, community governed, strategically designed to serve our community first, etc.

    At a different level DINFRA is an attempt to orchestrate a set of independent providers that will appear to the consumer as a single entity. Effectively DINFRA could become a decentralized alternative to Public Clouds in the long term. Lessons learned from DINFRA could apply to other industries too. Any industry with an existing level of automation and many independent players could be orchestrated similarly

    Development Status ๐Ÿ“–โ€‹

    The project has not started formal implementation yet. However we have performed a viability check of required deliverables.

    Most infrastructure deliverables belong to our domain of expertise per contributions made in the past to other open source projects, therefore is easy for us to ensure its viability. Intermediate interfaces don't have technical risk, they have important technical requirements when considering our project constraints but they are straight forward to deliver.

    Substrate deliverables are newer to us and imply a learning curve, however the amazing resources put together by the community at substrate.io: the tutorials, test frameworks, etc have allowed us to verify their viability.

    Future Plansโ€‹

    After the ink! version of the Dante protocol stack is fully tested, we would like to implement a pallet version for Polkadot ecosystems. Anyone who is integrating it can communicate with other ecosystems conveniently.

    Our next step is to work with many application-based projects to iterate our SDK for developers based on their needs, making web3's multi-chain interaction easier.

    At the same time, we will continue to improve and update our protocol stack as we use it. We will invite more project parties, developers, and end-users to participate and give their valuable suggestions.

    Security is the most important point in this field, so it will be fully tested on the testnet. And there will also be some targeted hackathon events related to security.

    Dante Network will be a long-term project because our final goal is to provide a simple, easy-to-use, secure infrastructure. At that time, the interactions between most of the chains in web3 will be as convenient as the interactions with terminal devices in web2 through the internet.

    Additional Information โž•โ€‹

    We highly endorse the philosophy of Web3 Foundation. We think the web3 world is expected to be an โ€œinternetโ€ of multi-chains, each of which can provide its own special features and every participant can share it worldwide. So there should be a kind of infrastructure that can provide consistent and convenient multi-chain interoperability for DApps in Web3 so that they can focus on their application business. At that time, DApps can serve the whole web3 market instead of staying in some certain ecosystem.

    In our idea, we think different chains are like realms in mythology. There are barriers for users to having universal transportation to travel around the different realms. And there is Bifrost to open a teleport between realms, but it is neither cheap nor easy. So inspired by this, we want to grow a โ€œWorld Treeโ€ that supports open and collaborative ecosystems in web3.

    It can take roots in the computing resources and storage infrastructures in web3 and web2 to provide orderly resource scheduling. And it can grow by offering non-differentiated data collaboration services for DApps in web3 and providing valid resources. This is why we have the Dante Network.

    @@ -18,7 +18,7 @@ If, instead, for at least 2 validators (between B, C and D) hash Z โ‰  hash Y, validator A is presumed a liar. Since to be a validator A needed both to provide GPU and/or CPU processing capacity and to buy and stake DataGen native tokens, is easy to impose an economical cost for the cheating validator A by making it loose staked coins as a consequence of its wrong computation. In this regard the Parachain acts as an authority for the random processes of the FB.

    We prefer the use of a Parachain, instead of two FB or a HB of our own FB, because of the improved resiliency that the Polkadot ecosystem can provide.

    We must underline that, even if the goal of this very complex design is to keep even the hardware layer as decentralized as possible (compared to a PoS network, where there is strong economic incentive for a validator to host the computing capacity on the top of centralized server farm like AWS) we canโ€™t prevent the validators hosted on centralized providers to participate to the network.

    The trade-off for such a result would so impede efficiency and low latency that, instead of trying to attain it (for some ideological reason of decentralization per self) we think we should try keeping the hardware layer of the network decentralized enough. We think that this can be attained as a collateral result of the above explained ECHO procedure (whose primary goal is to increase the overall efficiency and decrease the overall latency time of the network, by pairing users and validators on the basis of response time).

    This collateral positive externality happens since validators that are faster to respond to specific clusters of users are rewarded by the process with the right to provide the cloud computing power requested by those clusters, with meaningful consequences for the geographical distribution of the validators themselves: in some geographical contexts (US coasts or Western Europe), where the internet connection is fast and big server farms are close-by, this will keep the economic incentive for validators to be hosted in centralized server farms; on the opposite, in other contexts (like some parts of South-East Asia, Sub-Saharan Africa and LATAM), where broadband connection is slow or inexistent and server farms far away, there will be a strong economic incentive to set up independent hardware facilities to validate the activity of local or regional areas.

    Those independent validators, while not optimally located to compete with AWS-hosted validators for users in the โ€œnorth of the worldโ€, can also become validators of last resort in the case in which the centralized server farms are not providing service anymore (it can be due to technical outage or political pressure for censorship or other factors). As said, the goal is not to expel AWS-hosted validators from the Datagen network, but to keep it decentralized enough while being at the same time low latency and computationally efficient.

    The only computational activity that is happening off-chain is (following the example above) the act of validator A processing the raw data X and giving it to the user A, but: to receive the reward in #DG, validator A needs also to send the hashed data to both the other validators of the FB lighter chain and to the Parachain, since failing to do so will mean no reward because validator A would be processing off-chain data which wouldn't be recorded in the blockchain. Raw data is also sent independently from the user A to the Parachain and the correct pairing between hashing and raw data is always verified in-chain.

    Ideally, we would like to explore some technic to keep light the blockchains long-term to keep it clean of old unnecessary raw data and just having hashes long term (thatโ€™s why we like so much Polkadotโ€™s feature that allows blockchains to evolve without forking).

    So Datagen is NOT:

    Ecosystem Fitโ€‹

    The Datagen project fits into Polkadot ecosystem by expanding its use cases to the segment of decentralized cloud computing, whose importance can never be underlined enough for the healthiness of the broader Web3 and blockchain industries. Since the Datagen infrastructure is targeting mostly Web3 application providers as main customers to provide cloud computing to, this can loop in a positive feedback of new projects entering in the Polkadot ecosystem and as well as a very valuable use for a Polkadotโ€™s / Kusamaโ€™s parachain.

    In the Polkadot / Kusama ecosystem the most similar project is the Phala Network (https://www.phala.network/en/). Even if Phala Networkโ€™s goal is similar to the one of Datagen (decentralized cloud computing), the technical approach is radically different, since Phala is pursuing off-chain computation secured by a secure smart-contract platform.

    Both solutions are technically viable, but we feel that (without the presumption of being too knowledgeable about someoneโ€™s else target market or to give suggestions to someone else) Phala can be more appealing for legacy industries that want to interface blockchain (and Web3) to innovate existing business model (for example we think that Phala could be very compelling for health-tech applications that want to validate sensitive clinical data with a secure, encrypted network) while (from the feedbacks that we receive) we feel that in-chain computation would be more compelling for Web3 native applications, since in-chain computation is perceived as more decentralized and more secure (not necessarily rightly) by the semi-technical management that often decides what provider is more suitable.

    For the above explained reasons, we see Phala more like a complementary project than like an outright competitor (even if, of course, some marginal market overlapping could appear in some specific areas), since off-chain and in-chain computation, even if equally decentralized, can draw user-base from different contexts.

    In other ecosystems we can see different competitors, each one with a very different both technical and go to market approach (explaining them one to one will be too long to explain in this grant application), both off-chain and in-chain.

    Off-chain SONM (independent copy-cat of the Ethereum blockchain), Aleph.im (Solana, cross-chain compatible). And (more or less) in-chain: Akash (Solana Nodes + Cosmos), Golem (Ethereum), Cudos (L1, independent, cross-chain compatible), StackOS (Binance Polygon, Avalanche) and others.

    The existence of many competitors (each different from the other) in many different stacks is for us a confirmation that we are working on something that matters and we think that for the Polkadot ecosystem is important to harbor different cloud computing projects, with different (in some points complementary and in other alternative) approaches, both to help boosting the wider Web3 environment to shift away from centralized Web2 providers like AWS, Google Cloud, Azure, IBM, Alibaba and to acquire and retain valuable projects while competing with other major stacks, because cloud computing matters a lot in the web economy and in the web physical infrastructure and for a top stack like Polkadot / Kusama should matter where cloud computing, as a strategic asset, is happening.

    In particular is possible to observe that the Solana ecosystem is backing both one in-chain (Akash) and one off-chain (Aleph.im) decentralized cloud computing project, clearly in light of the different markets than in-chain and off-chain decentralized cloud computing can tap. In this way Solana ecosystem is positioning itself with a strong head-start to win the race for decentralized cloud computing.

    Team's experienceโ€‹

    Both founders (Angela & Luca) have a legal background. They entered in the blockchain space in 2019 (shifting carrier) because they both strongly believe in the transformative power that the blockchain revolution can have on society.

    After โ‰ˆ1 year of self-taught study of the blockchain technology and market, they incorporated B-Datagray in late 2020. At the beginning it was a very lonely but enriching journey, since they had 0 previous connection in the industry, 0 track record and 0 capital. Angela and Luca started being full-time on the project in January 2021.

    In Spring 2021 they started building the technical team (at the beginning all part time, due to the lack of capital) and not without encountering not particularly honest devs, while that made things more difficult short-term, long-term it allowed the funders to become more skilled in managing a team. Our currently beautiful team started to come togheter after summer 2021.

    In that period, we also entered in the XEurope Accelerator. Ren (with 7 years of coding experience and 5 of Solidity coding) was the first to become mostly full-time, in October 2021, before we were able to pay him a salary.

    In November B-Datagray received the first VC investment and to date we have 2 VC and 2 angel investments. We have developed all the tokenomic smart contracts, including a community governance smart contract to help smoothing the transition from the BSC to our Native + Polkadot blockchain and all of them have been audited by Certik. B-Datagray has also been recently finalist at the MIT Bitcoin Pitch Competition 2022.

    We know that we still have much to grow and to learn, but all the journey until here and now taught to B-Datagrayโ€™s founder a great deal about bootstrapping and managing a company and about doing much with very little.

    The ability and willingness to learn and grow and change and to work hard and to believe, even in the most difficult moment, and to find the resources, in the inner-self and in the other people, even when is seemingly and rationally impossible, in our opinion is more important than any learned skill for team and project leaders, since is an attitude that you have inside you and that you express in every aspect of your personal and professional life and that will be determinant to solve any of the multiple problems that will inevitably and unexpectedly occur during the projectโ€™s lifetime.

    All our devs (and our designers) are professionals and also very committed to learning and improving constantly their skills.

    Development Statusโ€‹

    What we have already developed (using Solidity) is all the tokenomic smart contracts regulating our DataGen token (#DG), including one to smooth the transition from the BSC network to the Polkadot / Native Datagen Infrastructure, with a rigorously decentralized community voting procedure (https://github.com/Datagen-Project/DataGen-Smart-Contracts/blob/main/contracts/MiningReservation.sol).

    In total our team has already developed around โ‰ˆ2K lines of code of smart contracts just for the Datagen project, excluding of course the default configurations (like lock.json , etcโ€ฆ), we are speaking of functional code. In addition to that, we have in private repo the functional code for the website and the sale interface.

    Regarding anyone in the Web3 foundation (and/or Parity Technologies) that we spoke with about our intended development with substrate we had: some technical email and email exchange with Gavin Wood, casual technical conversation with Richard Casey in a Dublin blockchain event, some calls (including technical explanations) with Rohan Joseph and Surag Sheth. One technical call with Justin Frevert. A long technical chat in person with Dan Shields at the MIT Bitcoin Expo 2022. A call with Santiago Balaguer.

    Diffy messenger

    • Team Name: BelSoft

    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    This application complies with a potentially interesting project โ€œPrivate instant messenger that uses on-chain identityโ€ mentioned in Open Source Polkadot Stack page in the โ€œSocial Networkingโ€ section.

    Project Overview ๐Ÿ“„โ€‹

    A lot of sensitive data is meant to be transferred between parties in a secure way, but most of the centralized messengers and mail agents, even secured ones, have a common point of vulnerability - a centralized database/backend that stores all the data and manages connections. Meanwhile, some entities or even industries as a whole have demand for secured private channels for exchanging messages, e.g. medical institutions, that exchange sensitive data with patients or with other market players.

    The aim of this project is to develop a secured decentralized messenger that doesnโ€™t store data on a centralized backend and uses personal Polkadot wallet credentials for chatting initiation and messaging.

    Project Detailsโ€‹

    P2p channels between users will be set using WebRTC. We will develop a Substrate pallet for exchanging SDP offers. For address discovery of NAT users we will use any public STUN server. All messages between users will be encrypted with userโ€™s public keys, so only receiving user could decrypt his messages using his private key of his Polkadot wallet. Also, the pallet will include a โ€œcontactsโ€ feature: a user will be able to tie names to wallet addresses and organize his contacts in a common way.

    Ecosystem Fitโ€‹

    The Diffy chat dapp is very in demand in areas where it is crucial to protect personal and other critical data from unauthorized access during interaction or communication between counterparties. The target audience is very wide: from medical institutions providing telemedicine services to remote financial services and corporate channels for transmitting sensitive information between remote divisions.

    In the Open Source Polkadot Stack we see the Uke Protocol Pallet project, that provides functionality to perform basic messaging and identity assignment to users on a given Substrate chain. Unlike Uke Protocol, Diffy chat dapp wonโ€™t use a blockchain for sending and storing entire messages as in case of mass use this feature will dramatically clog the blockchain with unnecessary information like "hello" messages. Our dapp will use a blockchain just for authorization purposes, p2p connection initiation and for personal encryption keys. History backup feature can be available on later stages of the project by storing files locally or in IPFS with putting just a hash sum in a blockchain.

A web dapp MVP mockup is shouwn below and the basic user logic is as follows. To establish a chat User A sends a short 1st message to User B (limited to 50 symbols as it is written into the blockchain). This message is sent with the connection request. When User B is on-line he receives this message with connection request and accepts it: automatically for users on his contact list and manually for requests from unknown users (connection request can be declined as well).

      โ€‹ BTC: 12q2NigsthG7YdxUBRbAaZPTHYj1xuEjCx

    Project Description ๐Ÿ“„โ€‹

    Dipole is an award-winning clean-tech company that brings blockchain technology into distributed energy resource management. Our aim is to provide service for the massive and fragmented distributed energy assets that will emerge in the near future, as well as facilitate the decarbonization of the energy system.

    Our EMS platform allows secure and reliable energy trading, where users can access a customized energy management module and trace their energy consumption in real-time.

    Working alongside the UN Environment Programme (UNEP), Dipole Tech already has been implementing regional energy allocation projects in communities in Manila and Bangkok, providing decentralized tools that allow customers to monitor, manage, and buy electricity in local markets.

    Dipole Oracle

    Due to large amount of onchain-offchain data interaction involved in the distributed energy scenario, together with its fragmented nature, there caused massive data interoperability in the reality. However Dipole is developing an independent Substrate-based blockchain on the Polkadot network (DipoleOracle), which records all stages of the energy industry and inter-operators with other systems.

    DipoleOracle connects Dipole chain and offline electrical hardware, ensure the safety and accuracy of offline power usage and transaction data, make them applicable for blockchain use. Which can enrich the ecosystem of Substrate and Polkadot, and bring the revolution of clean energy ecology in whole society.

    DipoleOracle includes four key components: Operator, GoodsOracle, PayOracle and Collector. The whole system provides the feeding and collecting of energy generation/consumption and transaction data.

    • Operator

    In the energy industry, electrical hardwares are extremely miscellaneous. The Operator module defines several common used electrical hardwares like electricity meter and charging point. The Operator module allows each registered electrical hardware to upload data online.

    • GoodsOracle

    In the energy industry, collecting real-time data from hardware such as electricity meter and charging piles has always been a technical challenge. DipoleGoodsOracle can be applicable to various electricity meters and protocols, which achieve a solid progress in this area.

    • PayOracle

    In the energy industry, periodical power transaction cause high needs of splitting bills for participants, third-party payments or stablecoins. PayOracle is able to complete all steps automatically. In area which don't have completed payment system like South Asia and Africa, PayOracle can enormously reduce the cost of payment.

    • Collector

    In the energy industry, collecting energy generation/consumption and transaction data costs a lot of manpower and material resources. With the Collector module, users can easily get data they really need, which can help them customize their business scenarios.

    Advantage

    • a customized oracle module can be applied to different kinds of variables data procession, such as electricity meter and charging point.

    • with the Operator module, any registered IoT device can easily upload data. Users can customized their set up like authorized uploading devices, filter malicious ones, and even build a scoring system.

    • with the Collector module, users can customize advanced calculating model such as dynamic data processing, incremental and filter statistics.

    The idea of a distributed key manager came to me during a class at Carnegie Mellon on shamir secret sharing. After coming up with a rough interface, I applied for a small undergraduate research grant from CMU, with Professor Nicolas Christin agreeing to be my advisor. This research led me to create the open source Kryptik wallet, whcih I have been working on for the past year. A short demo of the wallet can be found via this link. This wallet uses a simple version of the distributed key management system I described above.

    As part of this project, I also released a seedloop manager as an open source NPM package, which can be found here. This package allows developers to easily generate wallets and sign transactions across multiple blockchains.

    Milestone 1 - Research Paperโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide regular blog updates that document our discoveries on decentralized key management as we develop the paper.
    0c.Testing and Testing GuideSince this milestone is focused on creating and publishing a research paper, there is no need for a testing guide.
    0d.DockerThis milestone does not involve explicit software, so no dockerfiles are needed for testing.
    0e.ArticleWe will publish an article that summarizes the key findings of our distributed key management research for developers (who may not be interested in the nitty gritty technical details or security models).
    1.Formal InvestigationThe research period will be spent investigating the following questions about the kryptik key management system. What is the threat model? How can keys be synced across devices? How can the system include more than two shareholders? What is the ideal number of shareholders? Is there any application to social recovery? By the end of this period, I will have organized a sequence of proofs and thoughts that can be shaped into a paper. Each question and associated discovery will be documented via regular blog posts.
    2.Research PaperThis paper will include an in depth analysis of the research questions discussed above. Professor Nicolas Cristin of Carnegie Mellon will help advise the paperโ€“ he served as an advisor for my initial research grant from CMU. The paper will be released as an open source document on Github. We expect this open source key management knowledge to provide a strong foundation for future Polkadot/Kusama/Substrate wallet designers.

    Milestone 2 โ€” Reference Implementationโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide extensive inline documentation that describes the purpose of functions and parameters. This will help create a 'trail of knowledge' that developers can follow through the key management system.
    0c.Testing and Testing GuideWe will include a step by step guide that shows the distributed key management system works as intended. Unit tests will be included for critical functions like share generation/ recombination. Unit tests will be executed using vitest.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish an article that provides a step by step explanation of the distributed key management system and how each function is implemented in code. This will be published as a blog post.
    1.Vault ModuleThe vault module will provide a standard interface for storing a BIP 39 seed and multiple blockchain accounts on the client.
    2.Encryption ModuleThe encryption module will allow seed vaults to be locked/unlocked via a user provided password. The module will also use a randomly generated encryption key to create ciphertext for the BIP39 seedphrase when persisting vault storage on the client.
    3.Share ModuleThe share module will generate shamir shares for a given piece of data (in this case the encryption secret). This module will also allow shares to be recombined (according to the k of n secret sharing scheme) to reconstruct the original piece of data.
    4.Sync ModuleThis module will allow seed vaults to be synced across devices.
    5.Web DeploymentAnd finally, we will wrap these modules in a nice UI and deploy the interface to a website (likely using NextJs + Vercel). This website will allow developers to create a vault, sync their devices, and sign sample transactions. This will be accomplished via open source React components that developers can reuse in their own application. The deployed app will have Polkadot/Kusama/Substrate specific examples (address generation, signatures, etc) that will benefit future developers.

    Future Plansโ€‹

    After the grant is completed, I will continue improving the open source Kryptik wallet, which builds upon the distributed key management system described above. Work on the wallet interfaceโ€“ which has been sponsored by other grantsโ€“ will necessarily include revisiting the key management system and making improvements (such as adding the ability to sync key shares between devices). Beyond that, the research and published paper are a timeless body of knowledge that will continually benefit production implementations and new research on key management.

    Additional Information โž•โ€‹

    How did you hear about the Grants Program? I first heard about the grants program at EthDenver 2022. I then learned more about the program via the Web3 Foundation Website.

    The NEAR foundation awarded a $45,000 grant to develop the Kryptik wallet interface. This work wrapped the key management system with software that supports multi chain swaps, collectibles, payments, etc. I also received $20,000 from the Solana Foundation to provide open source documentation and Solana specific examples. Both of these grants are directed towards the Kryptik wallet interface, not the key management system which was devised separately.

    Finally, I received $500 from Carnegie Mellon to build the key manager and host the wallet interface.

    **How does this project benefit the Polkadot/Kusama/Substrate ecosystem? Asymmetric key management is an open issue that affects every blockchain ecosystem. An improved key management system will help improve wallet design which, in turn, will help improve the user experience of the Polkadot/Kusama/Substrate ecosystem. The research proposed above will provide foundational knowledge and software that can be integrated into existing Polkadot related wallets and in emerging wallets that have yet to be designed. In summary, successful execution of the grant will result in a simple and more secure way to interact with the Polkadot/Kusama/Substrate ecosystem. This will benefit users, who will have an improved wallet experience, and developers who can build upon a novel approach to key management.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Polkadot has increasingly grown the open source developer ecosystem. But there is currently no way to get an activity overview and easily track the development among different Polkadot organisations on Github, understand what is their status, track the contributions made by developers and get an idea on how the repositories evolve. Is really hard to understand how the Polkadot ecosystem is progressing since the data is scattered all over GitHub, with contributors, commits, issues, repositories and PRs data.

    The solution that CrossChain Labs presents is going to address the problems described above and will offer clarity on the open source Polkadotโ€™s developer ecosystem. This will be done by scraping the data related to Polkadotโ€™s organisations on GitHub and exposing it in a nicely designed dashboard that allows tracking the number of commits, repositories, contributors, PRs, the top contributors of the month, the evolution of commits and active contributors for each month over the last year and monitoring the recent commits that are being done in the various Polkadot organisations.

    Project Detailsโ€‹

    Deliverables:

    • GitHub Scraper that will collect all the required data from GitHub
    • DotPulse APIs that will serve to get the data from the scraper and interact with the DotPulse dashboard
    • DotPulse Dashboard that will include:
      • the statistics top section with the overall number of commits, repositories, contributors and PRs
      • contributors of the month
      • commits graph with info regarding the last 12 months
      • issues graph that shows the number of open and closed issues together with their total
      • graph of active contributors for each month over the last year
      • the recent commits section that shows the activity of the ecosystem over the last 30 days, with clickable links to open a commit, its repository or the developer's profile on GitHub

    Future Plansโ€‹

    Doterโ€™s development team is ChainBridgeNetworkTeam. As the name suggests, our long-term vision is to be a bridge between different blockchains. We will use trust-free cross-chain asset custody and on-chain mapping to enable digital assets on different chains to be interoperable.

    Doter is our first product. We believe that with the launch of the parachain, Doter will act as an important interaction bridge in the Polkadot ecosystem. After completing the development of 2 milestones, we will design Doter version 2.0. In version 2.0, users can easily manage private digital assets without memorizing mnemonic words. This will be achieved through an innovative technology. We believe in version 2.0 Doter will greatly reduce the threshold for users to use wallets, making Doter a real bridge between Polkadot and ordinary users.

    Additional Informationโ€‹

    ChainBridgeNetworkTeam has just been established for two months, but we have completed the basic module of Doter, and have designed the other two milestones. In the next two months, we will deliver all pre-designed functional modules.

    So far, we have developed at our own expense, but in order to have sufficient funds to support the realization of our long-term vision, we will try to obtain the support of investment institutions.

    In case we update some of our addresses but we want to restrict access to the users that previously were granted access to that address there will be an option to regenerate the cipher. This way everyone that had access to the old address won't have access to the new one.

    UI Designโ€‹

    The UI will consist of three main parts:

    My Identity pageโ€‹

    1-1-dashboard-2.png

    The user will be able to create his own identity and provide the addresses he owns on to his identity.

    Add Address

    In case some of the addresses the user owns change over time he will be able to edit them. Also, we can select the option to regenerate the cipher so that people that had access to the old address won't be able to access the new one.

    1-1-create-identity-4.png

    When sharing their identity users will also be able to select which addresses will be available for the person they are sending their identity to. The user will have to copy his identityNo but also the identityKey which specifies which addresses are accessible for the user that receives this key.

    1-1-create-identity-2.png

    Transfer pageโ€‹

    2-1-transfer-1.png

    Ther user will be able to transfer tokens to an identity by specifying the origin chain, destionation chain, and the receiver's identityNo.

    Address Book pageโ€‹

    Address book page

    The user will be able to add identities to his own address book. The identities will be added by providing the identityNo and some nickname for the identity. Also by clicking on the transfer icon on one of the identities the user will be redirected to the transfer page where the identityNo will be automatically filled out.

    3-1-Address-book-3.png

    When adding an Identity to an address book the user will also be required to provide the Identity Key which will be used for decrypting the identity's addresses when sending tokens.

    Ecosystem Fitโ€‹

    This project fits perfectly with the Polkadot ecosystem because it has everything we need to make it work. Polkadot is a multi-chain network, so a lot of users have different addresses on different chains for the same reasons we mentioned earlier. That's why the problems we talked about are important in this ecosystem.

    XCM is going to be a core component of our project since it'll help us transfer tokens between the parachains and the relay chain.

    Target Audienceโ€‹

    Our target audience is people who deal with sending assets frequently over the Polkadot network.

    0c.Testing and Testing GuideThe Identity ink! contract will be well tested with unit and integration tests.
    0d.DockerWe will provide a Dockerfile that can be used to test all the functionality delivered with this milesone.
    1.Identity ContractWe will write the code for the Identity contract using ink! so that our contracts can be compiled to wasm and deployed to any blockchain that implements the contracts pallet. The Identity contract will provide a range of functions, including creating an identity, adding addresses that are mapped to specific blockchains, and updating these addresses as needed. The contract will automatically generate a unique identifier, referred to as identityNo, for each identity. To ensure maximum security, we will allow the identity creator to specify the accounts that are authorized to modify the identity's addresses. This will enable the creator to retain control of the identity even if they lose access to the account used to create it.
    2.My Identity pageThe My Identity page will be developed using React.js, providing users with a user-friendly interface to interact with the Identity contract. This will include the ability to create a new identity, add or remove addresses associated with an identity, and access and copy the unique identityNo to share with others. This UI will also generate the Identity Key for the user's identity and will update it every time he adds a new blockchain address. This Identity Key will be accessible for the identity creator when sharing his identity. The interface will be based on the mock design presented in the UI design section.

    0e.ArticleWe will publish a Medium article that explains the details of our project.
    1.Address BookWe will develop the code for the Address Book contract using ink! so that our contracts can be compiled to wasm and deployed to any blockchain that implements the contracts pallet. The Address Book will enable users to create an address book and populate it with the identities they interact with most frequently. The identities will be added via their identityNo since our main goal is abstracting away addresses from the users. When adding an identity to an address book the Identity Key will also be needed. The address book will be stored on chain but the IdentityKey will be stored in local storage. The application will expect the user to provide the IdentityKey when using the app from a different device for the first time.
    2.Routing functionality.The code responsible for routing tokens to the correct destination will be incorporated into the frontend code written in TypeScript. This code will incorporate the necessary logic for constructing XCM messages to route tokens to the appropriate address. In cases where the destination chain is the same as the origin, a simple transaction will be executed. Because of possible race conditions where the identity owner is trying to update an address on a parachain while another user is trying to send funds to that identity on that parachain we introduce additional checks on the frontend. Before sending a transaction that will transfer the funds, the frontend will check whether there are any pending transactions happening that would change the address on the chain the user is transferring funds to. In case there is a pending transaction the user will get a warning and will be advised to wait for a moment and try sending the transaction again.
    3.Address Book pageWe will write the code for the Address Book UI using React.js. The UI will be based on the provided mock design that we displayed above in the UI design section. The UI will make it possible for users to create an address book and add identities to it.
    4.Transfer pageWe will create a user interface using React.js that will enable users to send tokens to a designated IdentityId. This UI will abstract away the complexity of addresses and leverage the Routing functionality described in this table(Section 2) to handle token routing. The UI design will be based on the mock design presented in the UI design section for optimal user experience.

    Future Plansโ€‹

    Our future plan is to expand our core functionality and add more features so that the tokens can be routed based on some different criteria. Some example of these ideas are:

    An exciting feature we would like to build in the future is enable token transfers between blockchains that are not part of the Polkadot network(e.g. Polkadot<->Ethereum).

    Proposal: Storage solution on Polkadot

    • Team Name: Eiger
    • Payment Address: Fiat 14.04.2023, 16:50 UTC+3
    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The main goal is to implement and maintain a Filecoin-like system parachain that uses DOT as the native token and is easily usable for all kinds of parachain projects in the ecosystem via XCM.

    Project Detailsโ€‹

    To accomplish this we are submitting this initial proposal to update our previous research and test how XCM could be used to allow the ecosystem to use this storage network.

    We are interested to build this because:

    • Native storage in Polkadot payable in DOT is not currently available
    • We have done the research 2 years ago.
    • After talking to community members in Decoded 2023 we noticed there is demand for this kind of functionality.

    We will not be using Trusted Execution Environments or Enclaves in this solution.

    Ecosystem Fitโ€‹

    Currently a storage solution native to Polkadot is missing, by building a system parachain anyone in the ecosystem will be able to access storage thru XCM, pay in native DOT and build more complex applications withour relying on other networks.

    Development Status ๐Ÿ“–โ€‹

    The goal of this proposal is to update the work we have done in the past to account for what has changed in the past 2 years in the Polkadot ecosystem and the advancements made in storage solutions like Filecoin.

    In addition to this research and updating the code, we will also test how XCM could be used by anyone in the ecosystem to interact with this storage.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Update research, update code and test XCMโ€‹

    • Total Estimated Duration: 1 month
    • Full-Time Equivalent (FTE): 1.5
    • Total Costs: 30,000 USD

    Two engineers will work together and in parallel to deliver these 3 subcomponents:

    1. Update the research done previously to reflect latest tech changes in Polkadot and Substrate. We want to figure out what it would take to implement a whole storage solution as a parachain without depending on 3rd part chains and evaluate what components need to be written from scratch and what can be reused.
    2. Update the code delivered in CGS or start fresh, whichever makes most sense. The scope of this is to deliver scafolding/template repository with boilerplace and dummy funcitonality. On top of this we can then test the milesone #3 below.
    3. Research and test how XCM can be used. Using the scafolding code from #2 we can test how XCM can be used to access the storage from a different parachain.

    Future Plansโ€‹

    This initial grant will produce a game plan on how exactly this storage network will work. Using this knowledge we will submit another future proposal to build this solution. Once this storage solution has been built, it will be voted on by a governance vote. If successful then this system parachain will be available to be used by anyone in the ecosystem and payable in native DOT.

    Overviewโ€‹

    Sybil-resistant faucet is a generic browser-based faucet solution that can be used on any existing parachain (substrate-based chain, either pallets or ink! smart contracts).

    Architectureโ€‹

    architecture

    Configurationโ€‹

    To make the faucet generic, it will store its configuration settings in .env file which will include the following settings:

    • DRIP_CAP - how many tokens to send per drip
    • DRIP_DELAY - how often user's can request to drip tokens (in ms)
    • REDIS_ENDPOINT - Redis instance endpoint
    • RPC_ENDPOINT - Substrate node endpoint
    • PORT - Substrate node port
    • FAUCET_ACCOUNT_MNEMONIC - mnemonic of faucet's wallet
    • NEXTAUTH_ENDPOINT - authentication endpoint
    • NEXTAUTH_JWT_SECRET - used to encrypt JWT tokens
    • TWITTER_CLIENT_ID - Twitter client ID
    • TWITTER_CLIENT_SECRET - Twitter client secret
    • GITHUB_CLIENT_ID - GitHub client ID
    • GITHUB_CLIENT_SECRET - GitHub client secret

    Ecosystem Fitโ€‹

    Many dApps are facing an issue where itโ€™s difficult to onboard new users. Thus, the goal is to simplify the process by making it easier for parachain and dApp developers to spin up their own faucets, and give users free tokens without people exploiting the system. In order to make the system sybil-resistant, centralised solutions like Twitter or GitHub login will be integrated, that will uniquely identify users, and enable dripping tokens to the account only once per given time period.

    Screen 2: Onboarding - Select Bounty

    Screen 3: Auditing Report

    Ecosystem Fitโ€‹

    Our platform can serve the project owners who have auditing requests for their projects, regardless of Web2 or Web3: as long as they can be compiled into LLVM (e.g., any Ink, Solidity, Rust, C++, etc. programs). The auditing reports and how they correlate with the on-chain statistics can also be reviewed by anyone: not just the project owner, but also the project users. Project owners can gain more trust by sharing the auditing reports backed with consensus with their users.

    Downstream DeFis, including insurance, using the auditing intermediate information and results can be deployed to our chain. As we enable the contracts pallet in our chain, the DeFis can be developed in the form of Ink smart contracts. XCM also makes it possible to pipeline the auditing results to other chains.

    Other projects can reuse the components of FuzzLand platforms. For example, the optimistic rollups pallet can be used by Layer 2 solutions. Collaborative manual auditing projects can also use the audit pallet or our chain by replacing the rollups pallet with consensus pallets.

    Decentralized Security Marketplace is a related RFP. QRUCIAL DAO is a related project in Substrate ecosystem. QRUCIAL DAO and FuzzLand both reach consensus about the auditing result. The fundamental differences are:

    Code4rena, Immunefi, Secure3, Sherlock, etc. are similar projects in other ecosystems, but they all rely on human auditors.

    2.Substrate module: auditWe will create a pallet for onboarding auditing requests, storing testcases, and distributing rewards. The pallet can also generate auditing reports in txt format automatically.
    3.Substrate chainModule optimistic_rollups and auditing will be integrated into a Substrate node, to enable auditor nodes to submit intermediate auditing results and information. This chain will integrate contracts, treasury, council, democracy and also other essential pallets, to build a full-featured blockchain.
    4.Offchain oracle clientsAuditor and validator nodes clients will be built by integrating the libraries built in the last milestone. The two clients will be able to interact with the chain so that the full auditing workflow shown in the Project Details can be accomplished.
    4.Web AppWe will create a web app, to let users easily interact with our substrate node. Users can create auditing requests, visualize intermediate auditing information, and view final auditing report.

    Future Plansโ€‹

    After finishing this grant, GensisDAO will be able to manage DAOs and proposal processes within it's own substrate based blockchain.

    The next two important steps will be

    Simoultanously, we will start building initial ink! infrastructure. Since we are heavily committed to shiny and elegant UX and UI, we want to heavily invest into user research and rapid feedback cycles to incorporate the needs of the community directly after the PoC that is build within this grant is live.

    The important outline for this project is to become a common good parachain, that acts as an infrastructure service for the ecosystem. Therefore extendable integrations with other important chains in the polkadot realm as well as attracting dao-specific protocols to extend the base chain functionality is part of the near term roadmap as well.

    Gluon will be a full-featured demo application for the TEA project once it is ready. So far, there are a few limitations that we are working on.

    Most items in this to-do list are part of the TEA Project plan. When TEA is ready, most of the features will be available too.

    Additional Information โž•โ€‹

    We started the TEA project in 2019. It has been under the radar until recently when it was released to the public. We believe the TEA project could grow large and become the backend service platform for a new type of dApps. These dApps can go beyond the limit of traditional blockchain technologies. Gluon is just one of the many possible demo apps. Once our honor gets granted, we will start looking for investors and hire a CEO and more developers to join us. We hope to maintain a long term and close relationship with the Polkadot community.

    Proposal: Dual-Key Stealth Address Protocol

    Milestone Delivery: Dual-Key Stealth Address Protocol

    Overviewโ€‹

    Many of todayโ€™s blockchains, including Bitcoin and Ethereum, are open and public ledgers in the sense that there are no restrictions on participation and all transaction details are visible on the blockchain. In a public ledger, the transaction entities are only identified by their blockchain addresses, which are derived from the corresponding public keys. Public ledgers are generally considered to be โ€œpseudo-anonymousโ€, which means that an address is linked to one person, but that person is unknown to the public. However, by analyzing the transaction graph and combining it with other information, it is possible to reveal the true real-world identity behind a blockchain address, as shown by recent research.

    The Green Lemon protocol is an anonymous NFT solution for the Polkadot ecosystem based on zero-knowledge proof and dual-key stealth address protocol: users deposit DOT to an anonymous NFT contract and then anonymously send mint, transfer, and other ERC721 functions to that contract via relayer.

    Project Detailsโ€‹

    The protocol implements the function of initiating anonymous transactions through zero-knowledge proofs and the function of hiding NFT owners through DKSAP.

    Currently, a large number of anonymous transaction projects use zero-knowledge proofs, such as Monero and ZCash based on the UXTO model, and Zether and Tornado based on the account model.

    Zether comes to our attention with its unique implementation, which uses the ฮฃ-Bullets protocol, does not require the generation of public parameters for the initiation ceremony, and uses the Elgamal encryption algorithm for homomorphic encryption and decryption of account balance, which are excellent features. But the Gas for anonymous transfers involving 64 accounts verified amounted to 36,152,558 on Ethereum virtual machine.

    Meanwhile, Tornado, based on zk-SNARK, performed well in terms of Gas, with a Gas consumption of 1,088,354 for deposits and 301,233 for withdrawals. After comparison, we decided to develop a zero-knowledge proof module based on zk-SNARK.

    DKSAP is a new privacy transaction protocol invented by rynomster/sdcoin in 2014. Since its announcement, it has landed in numerous blockchain projects (Monero, Samourai Wallet, TokenPay, etc.). It is characterized by the fact that the account needs to generate two sets of public and private key pairs, "scan key pair", and "spend key pair", the recipient of each transaction is encrypted and cannot be associated with a particular blockchain account.

    The protocol contains the following functions:

    • Deposit: The user generates a random note and deposits a coin to the NFT anonymous contract, so that can pay the relayer fees for anonymous transactions.

    • Withdrawal: The user will get back the DOT previously deposited, and nullifier the corresponding note.

    • Registration: The user registers the Scan public key and Spend public key to the NFT contract, and if the relayer sends the transaction to the chain, the user needs to pay the fee for the relayer.

    • Mint: The user generates the encrypted public key address ePub1(encrypted pub key) based on his scan pub and anonymously mint NFT through the relayer, the owner of this NFT is ePub1, and the user needs to pay the gas fee to the relayer.

    • Transfer: The user generates the encrypted public key address ePub2 based on the scan pub of the recipient and uses the private key signature corresponding to ePub1 to anonymously transfer the NFT, and the owner of the NFT is ePub2, and the user needs to pay a fee to the relayer.

    • Burn: The user pays the fee to relayer to burn NFT.

    • Other functions supported by ERC721, including Approval, ApprovalForAll, clear_approval, and set_approval_for_all.

    Ecosystem Fitโ€‹

    NFT sales reached $17.7 billion in 2021, up from $82.5 million in 2020 โ€” a jump of more than 200 times. Total NFT profits when reselling or buying also skyrocketed from $12 million in 2020 to $5.4 billion in 2021.

    Sotheby's - a renowned auction house with a history of nearly 300 years - generated $7.3 billion in sales in 2021, of which 10% was in private transactions.

    This gives us confidence that anonymous trading, the act of buying and selling without revealing the identity of the trader, is just as strongly demanded in the NFT ecosystem.

    As the first anonymous NFT application of web3 Ecology, we believe Green Lemon will have a positive impact on Polkadot. Users of NFT who value their privacy greatly will find it attractive.

Based on the current version, we will continue to develop other ERC721 protocol methods and related test cases, such as approve, approve_for, get_approved, base_uri, and token_uri. Additionally, we need to add an extra param into the message before hashing, which is the token nonce. Account nonce is unfit due to each token owner being a unique and one-time encrypted address. When an NFT is operated once, its corresponding token nonce is automatically added by 1. We think that token nonce can prevent replay attacks for signatures already sent to the blockchain.

    Overviewโ€‹

    Currently, the recommended setup is to have one active node per validator. The main advantage of this approach is that it removes the danger of equivocation, thus preventing slashing. The key drawback is the lack of a ready backup machine to takeover the responsibility of producing blocks, voting on finality etc. in case the primary one fails.

    The drawback can be somewhat remedied by having a backup node in sync, but without access to the session keys necessary for authoring blocks. The process of replacing the keys, however, is manual. Furthermore, the session keys cannot be replaced mid-session and this introduces a time delay for when the validator is active again.

    Project Detailsโ€‹

    Rather than relying on one validator node to perform the work, what if we had multiple nodes equally capable of taking part in consensus, yet still avoiding the risk of equivocation?

    Since all our validator nodes are trusted and we don't worry about censorship resistance, we can leverage a leader-follower model to ensure high availibility. Raft is a good candidate - it offers a simple consensus mechanism, fault-tolerance and performance. It ensures only one leader is ever in charge of interacting with the network, while the followers simply receive the state updates and automatically replace the leader in case of a failure.

    Following the feedback from the Parity developers team our solution is not tightly coupled with Substrate node as it adds too much complexity in the node. It should be implemented in a way that makes this optional and loosely coupled with the node.

    Ecosystem Fitโ€‹

    The goal is to present a solution that would update the current recommended setup of one active node per validator and allow to use multiple nodes.

    Development Status ๐Ÿ“–โ€‹

    This grant proposal is a follow-up to a discussion that began in autumn 2022. Since then we managed to receive some required feedback from Parity development team and we continued to apply their suggestions in the span of these few months. It allowed us to already develop most of the original scope.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    The development of the specified goal will be broken into 3 milestones, lasting 4 weeks (M1), 3 weeks (M2) and 2 weeks (M3).

    Definition of Done for each deliverable:

    At the end of each milestone:

    Deliverables ๐Ÿ”ฉโ€‹

    Milestone 1 - Block authoring, finalization & liveness PoCโ€‹

    The goal of the first milestone will be adding a switch to the substrate codebase, which will conditionally allow block production, voting or sending I'm online message. We will achieve this by introducing a PermissionResolver trait. Only for the purpose of this milestone there are going to be two trivial implantations of this trait. First configuration will grant the validator permissions and the second one will not. At this stage we only want to verify if hardcoded conditional logic works well with the nodes with the same auth key but different configurations (permission granted/denied). For the testing purpose we will provide an additional option to the CLI, to run a validator with one of the pointed configurations.

    0c.Testing and Testing GuideWe will provide unit tests and the guidelines for running and testing it the scope.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Update substrateModify the substrate code to conditionally submit blocks/votes for finalised blocks (GRANDPA)/I'm online messages.
    2.Update substrate client - cliModify the substrate code to conditionally grant or permit permissions. There will be option to run node in permission granted or permission denied mode). It will be useful to prove that permissioning works by running two nodes with same auth keys but different modes (permission granted/denied)
    3.Integration testA dockerised setup that allows to run network in setup described above.

    Milestone 2 - External service for permission grantingโ€‹

    The second milestone introduces a microservice which will test dynamic switching of the permission granting, during the validator's work. We will be able to test permission granting triggered whenever the block is produced, the vote is made on the finalized block (GRANDPA) and a message (I'm online) is sent for communicating liveness. Only the leader validator will be granted to run those actions. At worst, the author may miss a slot.

    The service should contain only basic logic (e.g. return true for node that asked first and false for following ones).

    Milestone 3 - Raft based current leader selectionโ€‹

    Replace the dummy microservice as an infrastructure component with a TiKV cluster used for leader selection. Each node should try to get authorship permission based on the KV (Key-value) state. Replace the current microservice client with a TiKV client and add corresponding logic.

    2.Integrate a Raft client into the nodeReplace the previous logic with a TiKV based one and modify configs to allow the TiKV client to connect to Placement Drivers. Placement Drivers (PD) is one of the components which stores metadata for the entire TiKV cluster. It is responsible for sending commands to the TiKV nodes. The minimum setup for PD is to manage three TiKV nodes.

    Hyperdot - Powerful data analysis and creation platform โ€” RFP

    Project Overview ๐Ÿ“„โ€‹

    This is a response for the Analytics Website/Data Platform RFP.

    Overviewโ€‹

    Crypto data is growing rapidly, and large data companies are not consider integrating them into their systems. However, multi-chain crypto data is of significant value to users. The hyperdot is a on-chain data platform for querying, analyzing, and creations, written in Rust. It provides users with powerful capabilities for data querying, analysis, and creations.

    With hyperdot, users can easily query and analyze crypto data from Polkadot, Kusama, and other parallel chains built on the Substrate Runtime. Hyperdot separates the indexing and computation of on-chain crypto data from the off-chain data storage, analysis, and querying, addressing scalability issues present in many data analysis platforms. Hyperdot offers multiple data engines to adapt to different scenarios.

    Hyperdot provides a dashboard similar to Dune Analytics and Chainbase, offering powerful data analysis and visualization features currently. Users can create queries using different data engines and generate visual data dashboards. Importantly, Hyperdot is dedicated to building a data analysis creations community where data engineers and data scientists can create and share their work based on Hyperdot's data, fostering collaboration and knowledge exchange.

    Project Detailsโ€‹

    The System Overviewโ€‹

    The Hyperdot project consists of two main system: hyperdot-node and hyperdot-frontend-end.

    hyperdot-Node will ideally integrate the data source of substrate-etl to provide an crypto-data query api on the chain

    hyperdot-frontend-end is built using tailwind css and next.js, creating a modern web dashboard. While it works similar to Dune Analytics, it has its own unique features. Hyperdot-Frontend connects to Hyperdot-Node to provide users with user-friendly chain data analysis capabilities. Moreover, it aims to establish a data analysis community where data engineers and data scientists can create and share insights based on the data provided by Hyperdot.

    The System Architecutreโ€‹

    Hyperdot will consider the success of the existing work of the integration community, for example, on the data source, we will choose to integrate substrate-etl as the data of hyperdot-node-front engine, at the same time, in order to maintain good scalability, hyperdot-node will also retain other options.

    Hyperdot System Architecture

    The system is mainly divided into three parts

    1. substrate-etl provides the relevant data warehouse, other ecosystems allow us to customize the index, and we will integrate their data as the data source of the system on demand
    2. hyperdot-Node will integrate data from common bins provided by substrate etl and provide apis for hyperdot-front-end
    3. hyperdot-fronted-end provides a user-friendly front-end interface for data analysis, exploration, and collaborative data analysis creation. It is built using modern front-end technologies. The interaction between hyperdot-fronted-end and hyperdot primarily utilizes HTTP, while GraphQL is used for handling complex data queries. WebSockets are employed for subscription-based data updates.

    The Live Demoโ€‹

    We have deployed a small live demo that you can play directly with.

    Querying the westend block data uses the index

    query2

    Ecosystem Fitโ€‹

    hyperdot will integrate data from Polkadot, Kusama, and Substrate networks by utilizing the infrastructure of substrate, substrate-etl, and other Parity technology communities. It will support multi-chain and multi-runtime environments. hyperdot will provide a dashboard that enables users to easily query on-chain crypto data using SQL language. Additionally, it will establish a community for data querying, analysis, creation, and sharing, allowing users to exchange insights.

    hyperdot is a data querying, analysis, creation, and sharing platform targeting a wide range of users, including data analysts, data scientists, project managers, and anyone interested in analyzing on-chain crypto data using hyperdot.

    Currently, we have not found similar projects in the Substrate/Polkadot/Kusama ecosystems. Moreover, data analysis systems that support multi-chain, multi-data engine integration with good scalability are rare in other ecosystems as well. We firmly believe that hyperdot will bring significant value to the community.

    QAโ€‹

    Q: Come up with a value proposition to make it viable: "how would the project stay sustainable and capture value?" to sustain operating costs

    A:

    • Sustainability: First, technically, we have a team with a good web3 background, so we don't get stuck with technical issues. Second, we were able to reduce our storage costs by relying on other projects' data warehouses, which allowed our projects to grow healthier.

    • Capture value: We believe that the ecosystem needs a "dune for substrate, but better" project that enables more powerful analytics for all users.

    Q: Interview a few parachains/ecosystem teams & researchers on the top 3 "dashboards" or interactive data use cases they'd like to see and include how you would solve that as part of the analysis and data platform RFP.

    A: We can't give a precise answer to this question, but we did a deep dive last week into existing data analytics projects in the ecosystem and, similarly, they always present data that users expect on top3. hyperdot is a little different,

    1. hyperdot allows anyone to create analytics dashboards using data provided by the substrate-etl repository, so the top3 ranking is not actually controlled by hyperdot
    2. However, we provide a favorites ranking for each dashboard, which can accurately show which data analytics dashboards are widely used by the community based on favorites

    Development Status ๐Ÿ“–โ€‹

    In 2022, Ryan started exploring Substrate and The Graph, and at that time, he attempted to add support for Substrate data on The Graph for private chains. This effort lasted for approximately six months.

    Starting from March of this year, Ryan and Ming were inspired by Dune and Chainbase, and they thoroughly studied the architecture design and implementation of these projects. Subsequently, we discussed the feasibility of building a multi-chain, multi-runtime, multi-data engine, scalable platform for web3 data analysis, creation, and a community of web3 data enthusiasts.

    We began designing and implementing Hyperdot, with Tania providing us with a simple data playground. Currently, we have achieved an MVP (Minimum Viable Product) validation of the core components, and they are functioning well. It is estimated that it will take another three months to make them work properly. Therefore, now is the time to apply for a W3F grant and introduce the work we have done to the entire Substrate community.

    Future Plansโ€‹

    After completing hyperdot and releasing the first version, we will integrate more data engines, including time series data engines (influxdb), OLAP analytics engines (Clickhouse), and distributed query engines (Spark).

    We will consider indexing more types of data, not just raw chain data, but also decoded dex and not data, as well as additional extrinsic data. Additionally, we plan to establish a mechanism where developers can propose data models they want to index through GitHub or the community. Once adopted, these data models will be incorporated into our data engines.

    We will also consider integrating ChatGPT to provide natural language querying capabilities (we are think it's something that's going to get the whole community excited about). Specifically, users will no longer need to be proficient in SQL and can run queries using natural language prompts.

    We will introduce a P2P structure for storage nodes to make them decentralized. We also plan to optimize and upgrade the UI based on user feedback, such as adding more dashboards and improving the data creation process. Additionally, we will explore integrating Grafana for better data visualization dashboards.

    Lastly, we expect to collaborate with foundations to promote our platform and showcase its value to more users. We will also engage with the community through platforms such as Twitter, YouTube, Medium, and others to introduce hyperdot.

    ISO-8583 implementation

    • Payment Address: 0xc42D0562BB4e53f5e9D888df35e1B91eA0f19cC3 (USDC)
    • Level: 2

    This application is in response to the ISO-8583 RFP.

    Overviewโ€‹

    ISO-8583 PoC implementation for Substrate.

    In this project I aim to implement the proof of concept for the ISO-8583 standard in Substrate. The implementation will be based on the extensive research done by Adit Patel in the following repository.

    I've already worked on the similar project for EBICS standard. I can leverage the knowledge gained from that project and research done by Adit Patel to implement the ISO-8583 standard in Substrate.

    Project Detailsโ€‹

    To fully imitate the ISO-8583 standard, I have divided this PoC project into two parts: infrastracture and blockchain. Infrastracture components are responsible for imitating the flow of the ISO-8583 message from the merchant to the PCIDSS compliant gateway. Blockchain components are responsible for further processing of the ISO-8583 message and settling the transactions/messages on the Substrate chain.

    Below is the implementation plan in a deeper technical detail from Adit Patel's research:

    Implementation plan

    Infrastractureโ€‹

    For this part, the implementation will consist of the following components:

    • Merchant: A hybrid web application, i.e can be used to either make the payment directly on Substrate chain, guaranteeing instant settlement, or via debit/credit card. It will consist of a mock marketplace and main work will be done on the payment checkout window. Depending on the payment method, the application will then send the payment request to the corresponding payment processor.
    • Payment processor (Stripe, Visa, Mastercard): The payment processor will be imitated by a web server that will accept the payment request from the merchant, compose the ISO-8583 message and send it to the gateway. It will maintain the offchain ledger (database).
    • PCIDSS Compliant Gateway (Oracle Company): The gateway is the first part of the centralized oracle. It will be mocked by a message broker that will process the incoming ISO-8583 messages from the traditional network and pools them for the offchain worker to query. It is also responsible for maintaining an up-to-date record of the offchain and on-chain ledger, validating messages, keeping track of chain events and composing new messages in case there is a mismatch between the two ledgers.

    For the above componenets, there are already some open source projects that can be used. Namely:

    • ISO-8583 implementation in Javascript: I will use this library in mock web server and the merchant application. Opted for this library since it seems to be well maintained and documented (the Rust version has the last commit from 2019).
    • RabbitMQ: I will use RabbitMQ as a message broker for the gateway. It is a well known and widely used message broker. It also has a Rust client

    And for the merchant app, below are the mockups of payment checkout window:

    Card payment

    Payment on-chain

    Successfull checkout

    Blockchainโ€‹

    On the blockchain side, there were three key components that were proposed in the research:

    • A centralized oracle
    • ERC-20R smart contract
    • Substrate chain

    However, from my previous experience building the EBICS PoC and generally as a more experienced Substrate developer, I believe the first two components can be simplified to:

    • An offchain worker (OCW): It will act as a second part of the oracle, i.e it will query for the ISO-8583 messages from the gateway and will send them to the Substrate chain. The only way for the chain to receive the ISO-8583 messages will be through the OCW. This will ensure that the chain is not spammed with unnecessary messages and will also allow us to hide sensitive information like account numbers and authorization codes.
    • Pallet: pallets are more flexible and a lot easier to implement and maintain than smart contracts. It will implement the ERC-20R standard and will settle the transactions on the Substrate chain.

    Challengesโ€‹

    One of the main challenges for this project is the reversability of transactions in the ISO-8583 standard. The standard allows for the reversal of transactions in case of a dispute. This is not a problem for the traditional payment networks since they are centralized and can easily reverse the transaction. Although, ERC20-R standard has a revert function, it becomes complicated when we try to get back the funds that are already spent. I will have to do more research on this topic and will try to come up with a solution.

    Inspirationsโ€‹

    EBICS PoC implementation offers some insights and inspiration, however, the ISO-8583 standard is a lot more complex and will require a lot more robust and complex infrastructure. Similarly, on the blockchain side, the reversability of transactions will pose a great challenge. Therefore, large parts of the blockchain components will need to be rewritten from scratch or significantly refactored in best case.

    Ecosystem Fitโ€‹

    A quote from Adit Patel here:

    Supporting international standards would smooth the connection between crypto and traditional financial institutions and is a go to market strategy for several competing projects. While those efforts are focused on the newer ISO-20022, not ISO-8583, there is significant value in being the first blockchain to support traditional banking infrastructure and dislodge incumbent networks such as SWIFT or Visa/Mastercard.

Web app will also handle necessary balance checks by querying chain to early return invalid transactions. Users will also have an option to use their mock plastic cards.
    2.Payment ProcessorI will create a NodeJs server that will receive payment requests from merchant app, compose the ISO-8583 message and send it to the gateway. This server will also be responsible for keeping the offchain ledger, similar to how traditional networks currently operate.
    3.PCIDSS Compliant GatewayI will create a message broker service that will serve as a centralized oracle gateway. It will process and pool incoming messages from the mock payment processor. Oracle will maintain a constant connection to Substrate chain, to ensure the validity of messages in the pool before they are consumed. For example, if there is a transfer from Alice to Bob, oracle will ensure that Alice has enough funds both offchain and on-chain, tx_id of transfer is not already on-chain, etc. It will also include mechanisms to ensure the message is being consumed by genuine offchain worker and not some other malicious consumer. For this step, some basic cryptographic authentication method will be used.

    Project Overviewโ€‹

    Response to RFP 20022

    Cross-border payment example as proof of concepts, leveraging the unique Off-Chain Features of Substrate that show the advantages of using ISO20022 together with Substrate.

    Overviewโ€‹

    The project is an ISO20022 based cross-border payment proof of concepts implemented with Substrate off-chain computation and indexed data storage.

    ISO (International Organization for Standardization) 20022 is becoming the de facto global data standard for payments and electronic data interchange already adopted by many countries. However the ISO20022 are all about centralized fiat based payment rails among privileged global financial institutions.

    Blockchain based decentralized payment solutions can provide efficiency, low latency and cost savings potentially benefiting billions of users worldwide. There are ledger based currency exchange and remittance network such as the real-time gross settlement system from Ripple Labs Inc. yet it is permissioned, centralized and not capable of cross chains.

    Polkadot, with its multi-chain architecture, security and cross chain interoperability, is uniquely positioned to support ISO20022 compliant global payments. This project is a Proof of Concepts to understand what it takes for Dotsama ecosystem to support a cross-border payment use case, leveraging on XCM, OCW and Substrate pallets, challenges and recommendations.

      • Our research shows that many challenges exist to support ISO20022 compliant cross border payment use case
        • A traditional ISO20022 cross border payment means multiple transactions in various ISO20022 message types, with multiple hops among financial entities inter-connected via custom agreements / fee structures / sfovereign regulations, with no standards
        • ISO20022 and XCM are at different granularies with a single cross-border payment mapping to a set of XCM messages with flow logic
        • ISO20022 payment transactions have different fees / charges based on many factors
        • Traditional cross-border payments on fiat rails do not have blockchain "gas fee" concept
        • Data type incompatibilities between IS20022 and XCM, such as date and time, currency, float, array, etc.
        • No out of box support of XML data processing and mapping such as XSD transformations
        • No native foreign exchange / currency conversion support
        • XCVM with instruction set for XCMP messaging is a totally different paradigm as compared to traditional message passing
        • No existing gas light solution to handle compute intensive and indexable data storage for off chain payment processing

    • What your project is not or will not provide or implement

      • This is not a complete cross border payment system given the scope of proof of concepts
      • Likely this is the first ISO20022 project on Dotsama, there could be unexpected gaps discovered
      • This project is not a full blown IS20022 implementation on Dotsama / Substrate but explore to expose gaps for future endeavors
      • This project is not about payment identity / KYC / AML solutions
      • This milestone is all about understanding what it takes to support ISO20022 compliant cross-border payments on Dotsama, not implementations which could come later with more clarity coming out of this project

    Idavoll Network

    • Proposer: jasonberger0
    • Payment Address: 1NNtuqwroKc9cMZdigpLdNLrzPKCp7zkXT

    Project Overviewโ€‹

    Overviewโ€‹

    Idavoll Network is an decentralized organization platform that provides infrastructure and services to users of the Idavoll Network and Polkadot ParaChains. Each Idavoll Network organization exists as a set of modules that define the organizationโ€™s stakeholders and their associated rights and privileges. Idavoll Network will implement idavoll court in the future, developed and maintained by Idavoll Network holders. The idavoll court can be used by organizations, to resolve subjective disputes with binary outcomes.

    Project Detailsโ€‹

    Idavoll Network is a decentralized organization network based on Substrate and run as a parachain on Polkadot. Idavoll Network has a set of pallets to achive the management of DAOs: orgnaization module, voting module, token module and finance module. By chanining these modules together, everyone can define a DAO which constrain how actions can be performed within the organization. We will give some common scenarios to explain how the idavoll pallets use predefined rules to active the standard forwarding operations.

    idv

    Common Scenariosโ€‹

    Transfer Assetsโ€‹

    • the Organization members initiate a proposal to transfer organizational assets through the Finance Module. The proposal is confirmed on the Vote Module and required to complete the voting results of the organization members within a certain period of time. The voting results are required to meet the asset transfer rules in the Finance Module. The approval votes are greater than the minimum approval votes. Only after the number and the number of negative votes are less than the limit of the maximum number of negative votes, can the proposed movement of asset transfer within the organization be realized through the Finance Module.

    Snapshot Vote Decisionsโ€‹

    • We can combine the organization module, voting module and token module to implement the decision management process. Users can create any proposal (an easy-to-understand term that the proposal must follow) and initiate the voting process. All users holding the corresponding tokens can participate in the voting. The voting ends, the Idavoll Network will count the voting results of the voters according to the snapshot of the current blockchain state. The voting results will be used as a community consensus and will be permanently stored on the blockchain.

    @@ -13,7 +13,7 @@ ISO-8583 datastreams reveal far too much information to ever be publically exposed. Here neapay proposes using ISO-8583 to connect to Coinbase to purchase crypto. However you can see that once the datastream is unpacked, the user's financial details are immediately revealed. Unpacking data is a trivial process that has no security, ISO-8583 data is not encrypted. Of note is the exposed primary account number (F02_PAN: 9876 5000 0030 6082). Most people would recognize this number faster as their credit card number. While it is possible, and implemented in practice, to transfer the data securely between two, trusted centralized servers using Diffie Hellman key exchange, research is needed to construct a way to place ISO-8583 data on-chain securely, if it is even possible. There are also laws about retaining this information for a fixed period of time, for example, Minnesota, a US state mandates that this information is deleted within 48 hours of reciept which is at odds with the enduring, provable structure of a blockchain.

    Transaction Reversals Outside of simple purchases, one of the most common messages communicated over ISO-8583 are chargebacks. About 0.6% of all transactions are ultimately recalled, though it varies by industry. ISO-8583 was designed to handle this process seamlessly and has a reserved MTI code for all chargebacks and reversals (x4xx). Unfortunately, modern blockchains by design are irreversible. From the original introduction of Satoshi Nakamoto's white paper.

    While the system (traditional finance) works well enough for most transactions, it still suffers from the inherent weaknesses of the trust based model. Completely non-reversible transactions are not really possible, since financial institutions cannot avoid mediating disputes. The cost of mediation increases transaction costs, limiting the minimum practical transaction size and cutting off the possibility for small casual transactions, and there is a broader cost in the loss of ability to make non-reversible payments for nonreversible services. With the possibility of reversal, the need for trust spreads.

    Supporting ISO-8583 functionality would require building a new token standard, or making changes to the operation of the blockchain to allow reversible transactions. A solution highlighted in the original bitcoin white paper is automatic escrow accounts, but research would be needed to identify the best way to implement these accounts or if there are better solutions.

    Authorizations and Privilages This leads to another major challenge. In traditional banking, the users are not equal. Certain entites such as the issuing bank or network can make decisions unilaterally without recourse. An example of this would be the aforementioned chargeback or transaction reversals which can be performed by the issuing bank or network for any reason. Blockchains operate on an equivalent peer model, and it is an open question as to how to authorize a super user and who should maintain super user priviliages over the entire network.

    For Milestone 1 we aim to deliver a robust implementation proposal with solutions to these challenges. While likely no the intent of the RFP, significant foundational reserach has to be done into the feasibility of integrating ISO-8583 with Substrate (or even blockchains in general). These challanges have significant risks and may prove unfeasible. For example, it is possible that it is ultimately too risky to store ISO-8583 data on-chain or even expose it to nodes. While we do not aim to make such determinations during Milestone 1, we will provide a detailed documentation of the major challenges, options for addressing these challenges, and the major tradeoffs. We will also try to summarize what others have done in this space.

    Ecosystem Fitโ€‹

    Supporting international standards would smooth the connection between crypto and traditional financial institutions and is a go to market strategy for several competing projects. While those efforts are focused on the newer ISO-20022, not ISO-8583, there is significant value in being the first blockchain to support traditional banking infrastructure and dislodge incumbent networks such as SWIFT or Visa/Mastercard.

    Where and how does your project fit into the ecosystem?

    This project is the first phase of a wallet project. Although, we think that our Trusted Transaction Validation protocol could bring a novel approach to address UX/UI security issues regardless of other features of our frictionless wallet. We designed our validation transaction protocol to benefit to other wallets or Dapps. We think it could also be complementary down the road to mobile light clients like Substrate Connect (check Future Plans section).

    Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    We want to target Dapp providers in the DeFi ecosystem with developer tools to integrate our solution with their Dapps. We think that our value proposition should be attractive to them. At the same time we want to target newcomers with a Robinhood wallet for Defi that includes an average dollar cost feature.

    What need(s) does your project meet?

    The need for a wallet to be simpler to set-up and use, as well as the need for higher security to address the growing malware/banking trojan threats.

    Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    Math Wallet and Gluon are close to our solution.

    We think that we could bring a better user experience, security and performance, thanks to a highly scalable layer 2 based on SubstraTEE:

    2.part of GCF external service in TEEWe will migrate the circuit garbling service part in TEE/Intel SGX
    3.android client garbled circuit evaluation updatedwe will update the evaluator on android with the Fancy-Garbling scheme

    notes regarding this change:

    1: We have decided to let the creation of the Master/Configuration logical circuit part managed by ocwCircuit outside of TEE because api_circuit is not critical from a security standpoint in our use case.So, we have no reason to manage it within a TEE.

    2-3: We replaced the GPL code of JustGarble by Fancy-Garbling because we can't use GPL licence with a TEE framework. Fancy-Garbling is a classic garbling scheme using a different circuit file format and mainly design for multi-party-computation use cases. So, the change slightly impacts circuit garbling performance. As a consequence we aim at proposing a slight refactoring of the code to ensure performance optimization in a follow-up grant to achieve performance at least comparable to JustGarble. Potentially adding a permutation based garbling scheme like the one used by JustGarble if required.

    @@ -13,7 +13,7 @@ Interstellar aims to change this perception through a new approach and technology.

    We strongly believe that securely linking and registering access device security components with a blockchain-based autonomous system is an extremely powerful concept. It can provide a future-proof solution for addressing the current security, usability, and privacy issues associated with current centralized non-custodial wallet software.

    In terms of security, this approach utilizes the current and future mobile device security capabilities by implementing a secure distributed protocol. It addresses the current lack of third-party protection and management while also adding the necessary decentralized backend services to enhance security against evolving cyber threats.

    Regarding usability, this approach simplifies the user experience by adding transparent services like Instant Onboarding.

    Privacy can also be addressed using methods such as stealth addresses and other private schemes.

    Additionally, implementing this approach increases the overall system's auditability, potentially enabling the management of a guarantee fund to aid users in case of issues.

    Furthermore, this approach can enable new types of recovery schemes that would be impossible without a secure decentralized autonomous system backend.

    A highly secure and convenient wallet system is necessary to combat cyber threats and ensures larger adoption.

    Our solution transforms mobile devices into cold wallets, with private keys protected at the hardware level:

    This hardware security, combined with a Trusted Transaction Validation Protocol, offers robust protection against state-of-the-art malware, including banking Trojans, and prepares for future targeted attacks.

    Interstellar is more than a wallet, we have designed a novel secure access layer for web3 managed with a blockchain that register mobile hardware/secure elements/TEEs to protect transaction with a strong multifactor authentication (based on hardware and software computation privacy scheme i.e. garbled circuit).

    Using a blockchain for the management of multi-chain transactions offers extra security and auditability features and dramatically increase convenience for the user:

    In the medium/long term (see future plan for more details):

    This approach achieves a highly secure level for newcomers to easily onboard web3, and serves as an alternative to hardware wallets for crypto veterans.

    Our technology has the potential to disrupt the hardware wallet, smart contract wallet, and even hot wallet markets.

    At parisDOT.comm we had a fantastic opportunity to present our project to the leading teams in the Polkadot Parachain community. And the feedback we received was nothing short of extraordinary. Our solution, which aims to provide both hardware security and user-friendliness in a wallet solution, struck a chord with the teams.

    Their positive response is a testament to the importance of a solution that addresses this critical need in the Polkadot ecosystem and beyond. The teams were not only impressed with our solution, but they were also eager to put it to the test as soon as it becomes available.

    This is a major market fit milestone for us, and we're thrilled to have the support of such influential players in the Polkadot community. We're dedicated to delivering a solution that meets their expectations and contributes to the continued growth and success of the Polkadot ecosystem.

    We are in active conversations with some of the teams we met there, and continuously have new discussions with new teams also beyond the Polkadot ecosystem. So far, everyone is impressed and enthusiastic about the solution.

    1.Display Circuit updateWe will modify the current display circuit to enable a more comfortable user experience by decreasing the cognitive load needed for the user to read the screen. - likely by adding specific sub-circuits to manage a set of probabilities of displaying segments for each frame, then fine tuned segments ON/OFF per frame to improve readbility
    2.Light security screenWe will provide a less secure but very comfortable to read secure screen version using fading with less blinking (link) - this non-screenshot proof version will be used later with our adaptive security framework

    Additional information (reason for amendment):

    As we prioritize the user experience and aim to showcase the FPS improvement and overall viusal improvement for the user compared to the previous milestone, there is no need for a Docker here. Instead, we provide an offline demo app to simplify the evaluation.

    However, if you'd like to test the full pipeline for this milestone, we can provide you with both a Docker and an online version of the app and the related demo tutorial.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    It's a very highload action to store large amounts of data on-chain. The most-common and useful solution for decentralised apps is to use IPFS as a data storage and store on-chain only hashes. Our team inspired by the OrbitDB will focus on the scalability, decentralised, easy-learning solution for substrat developers that want to manipulate big amounts of data easily.

    Key advantagesโ€‹

    • Usability - just integrate and code
    • Security - built-in encryption
    • Scaling - ready for changes and big data

    Available storage data typesโ€‹

    • Key-value - simple key-value storage
    • Hash - hash storage like Redis hash

    Motivationโ€‹

    Working a lot with blockchain technologies, our team found that itโ€™s data-driven, and thus there are rapidly growing interests in integrating them for more secure and efficient data storage and sharing.We are convinced that blockchain technologies change the world, and have been working hard to create more transparent solutions. We designed and built core infrastructure for decentralised projects.

    We have been observing and learning Substrate technologies and find Polkadot as the best ecosystem for us to join depending on technology and strong market position. We believe that our protocol will be useful for other projects in the Polkadot ecosystem.

    Project Detailsโ€‹

    Substrate pallet provides a configurable database module allows to store and manipulate a big amount of data. Pallet works as an offchain worker and connect data between blockchain and ipfs via offchain::worker.

    Encryption moduleโ€‹

    Built-in encryption module allows to create a secure database and encrypt all data before its uploading to the database with user account keys. With enabled encryption only account users have access to the database. Data could be decrypted via Web-application after receiving. Module is based on asymmetrical cryptography and uses an account public key to encrypt data on the blockchain side and a private key to decrypt data on the client side.

    We plan to make it based on ed25519 crypto scheme and use ecies-ed2551 crate to implement encryptions on backend side.

    scheme A

    • receive data by RPC request
    • Encrypt data by account public key
    • Insert encrypted data into ipfs via offfchain::ipfs
    • Insert received ipfs hash into storage

    scheme B

    • catch request to get data by RPC request
    • get ipfs hash from storage
    • fetch encrypted data from ipfs via offchain::ipfs
    • receive encrypted data in RPC response
    • decrypt data using user account private key via app ddecryption module

    Technical stackโ€‹

    • Rust - main language

    • Substrate - blockchain framework

    • Substrate-front-end-template - web-app template

    • Offchain::ipfs - substrate-ipfs bridge

    • IPFS - data storage

    • ecies-ed25519 - encryption crate

    Public Methodsโ€‹

    • KeyValueInit(name) - initialise new keyValue database

    • KeyValueSet(key, value) - set given value in keyValue database

    • KeyValueGet(key) - get value for given key

    • KeyValueDel(key) - delete value from keyValue database

    • KeyValueAll() - fetch all values from keyValue database

    • HashInint(name) - initialise Hash database

    • HashCreate(hashName) - create new empty cash

    • HashSetField(hash, field, value) - set hash field with given value

    • HashGetField(hash, field) - get hash field

    • HashDelFied(hash, field) - delete field from hash

    • HashAll(hash) - get all hash fields

    Storageโ€‹

    • Data Map - mapping ipfs hashes and data keys
    • Key-value - database meta info

    Scheme 1. Palett structureโ€‹

    scheme C

    Data uploadingโ€‹
    • Rpc/wss request to pallet to insert data
    • Validating data based on database schema
    • Formatting data
    • Encrypted (if needed)
    • Store to ipfs via offchain::ipfs
    • Retrieving ipfs hash with data
    • Store ipfs hash into pallet storage

    Future Plansโ€‹

    Further development (adding new data storages, indexing system, concurrency queries)

    Community engagement

    Also we want to realise this idea and integrate it as the core part of our project in the healthcare sphere โ€œTrusted Health Councilโ€. We have reached agreements with medical institutes in the field of further development of the project concept such as belgium "University of Antwerp" and russian "Pirogov Medical University" on the further development of the project, in particular, providing access to their databases, as well as the creation of specialized departments on the basis of institutes for the innovative development of universities, promotion, participation in healthcare exhibitions and advisors.

    The development of the prototype and initial research have been started with the personal funds. We have tried for a General Grant first, and decided to start with an Open grant Program relying on recommendation. Also we have applied for the Substrate Builders Programm and have proceeded with a general interview to iterate around steps going forward. We have also opened a dialogue with Blockchers & IPFS.

    Tip or Donate KSM Embeddable Button

    Project Overviewโ€‹

    This application is in response to following RFP https://github.com/w3f/General-Grants-Program/blob/master/rfp-proposal/ksm-tipping-button.md

    Overviewโ€‹

    As proposed in the RFP we will make a standalone embedded "Tip or Donate KSM" button with customizable text by the website owner. The button's embedded code will sanitize the current URL, check if the tip for the same URL already exists and is active. If available and once clicked button will ask for permission to connect to PolkadotJS extension, offer to Propose Tip or Donate directly. If proposing a tip, it will inform the user of the funds needed to propose a tip (transaction fee and deposit), check if the user is a Council member and optionally allow him to attach a message. Only Council members are allowed to propose the amount once the tip has been created. Once the tip is proposed the button will be disabled. If donating directly it will ask for an amount and allow visitor to enter a custom note.

    Considering the request for this implementation not slowing down the websites and several performance tests from different sources exhibiting Svelte as the optimal choice performance-wise we are strongly considering using Svelte as a development framework. Before committing to that decision we will conduct the performance tests ourselves and decide if it is the optimal solution. We will be using polkadot.js API.

    Milestone 1 โ€” Literature review and conceptual framework specificationโ€‹

    Our approach will begin by conducting a comprehensive literature review to identify key concepts and principles in ontologies for blockchains. This includes studying the existing applications and ontological frameworks that have been developed for blockchain systems, as well as other relevant research in the fields of symbolic representation

    Once the key concepts and principles have been identified, the next step is to specify a conceptual framework that incorporates and relates these concepts and principles. This framework will be designed to express the fundamental entities and relationships that govern the Polkadot ecosystem, and it will be flexible enough to accommodate the ongoing evolution of the technology.

    Koi Metaverse

    Project Overview

    Overviewโ€‹

    Introductionโ€‹

    Koi Metaverse aims to unlock the next-gen GameFi metaverse economies and it is building the digital collectibles platform for virtual GameFi NFTs. It is a fish collection blockchain game that combines token economy and NFT assets. It consists of a series of smart contracts, and all of the in-game assets belong to its players. Players can play to earn by collecting high mining power fish and growing them, creating a positive self-circulation.

    If pure-bred mining fish is reproduced, you can lock it into the pictorial book to mine the governance token, and use it to participate in the other DeFi activities. Koiverse creates a variety of NFT assets in the form of fish images and aims to become the BearBrick in the blockchain GameFi space and the brand new Axie Infinity on the Polkadot network.

    Team Interestโ€‹

    Our team has more than 10 years of game development experience and 3 years of blockchain game development experience. The number of accumulated registered users in the previous games is over 50 million globally. The highest number of active unique users exceeded 1 million. Koi team is also experts in innovative gaming mechanisms, sidechain implementation, tokenization economics and decentralized wallet integration.

    We are creating new kinds of virtual assets on Blockchain. Certainly we are the true Metaverse believers and builders who have strong motivation to unlock the Next-Gen GameFi Metaverse Economies. In Metaverse powered by Blockchain, we have seen the following core disruptive innovations:

    • Blockchain infrastructure leads to the property rights revolution. With blockchain, we can imagine a world in which contracts are embedded in digital code and stored in transparent, shared databases so that everyone could have the real ownership of properties.
    • Non-Fungible Token (NFT) changes the types and rules of games. NFT is a new form of unique digital asset designed to show someone has ownership of a unique virtual asset. It will become a new trend of virtual assets for creating, trading and collecting.
    • Tokenization and crypto creates brand-new business models. Crypto unlocks new rules of business models in game, like the concept of Play-to-Earn (P2E) which created new types of jobs and professions in digital Metaverse economies.

    • withdrawNft() - withdraw the staked nft
    • withdrawNftAll() - withdraw all staked nfts
    • getReward() - acquire mining reward

    NFT Assetsโ€‹

    Fish NFT

    • Each fish is composed of 14 genetic components: shape, color, pattern, eyes, mouth, pectoral fin, dorsal fin, caudal fin, decorations, invisible components, and breeding sequence.
    • The highest mining power of the fish is determined by the sum of each partโ€™s mining power, gear buff, and the cultivation level.
    • When certain fish genes match, a mining power bonus and pictorial books will be activated.

    Fist Tank NFT

    • The fish can grow up in fish tanks. The cultivation time cycles are 10 days, 30 days, and 90 days, which respectively come with a maximum 30%, 120%, and 400% mining power increase.
    • Each fish tank may have unique features and different capacities.
    • Fish tanks and fish cannot be sold during the lock period.
    • In the cultivation time, the fish cannot engage in mining or breeding.

    Game Functionsโ€‹

    Fish Breeding

    • The only way gamers can mint new fish NFT assets is to breed fish. The cost of the very first breeding is determined by the average mining power P of the parent fish and the average ecological mining power AP. The cost F=K*P/AP, tentatively K = 500.
    • The progeny genes are inherited from the parent fish genes, and each parent has a 50% chance to propagate its genes.
    • The scarcity of the fish gene is classified as normal, scarce, epic, and legendary. The scarce, epic, and legendary genes, respectively, have a 50%, 35%, and 25% chance to be inherited. There is a 1% chance to increase the gene scarcity level, or the genes will mutate into random and normal genes.

    Fish Mining

    • All fish with mining power can obtain reward tokens every day proportionately. The amount of reward token available to mine per day (M) is related to (F) the total sum of the fish (mining power>0) participating in mining. M=K*F^0.9๏ผŒK as a constant, tentatively K=50.
    • Only the fish that are not being sold, bred, or locked by pictorial books can participate in mining.
    • Every time a fish participates in mining, it loses 4% of the mining power until it reaches 0.

    Pictorial Book Mining

    • A gamer can activate a pictorial book when acquiring some pure-bred fish with the built-in suites.
    • You can start mining reward tokens if you lock the right fish into the pictorial book. The locked fish must have full mining capacity.
    • There are 4 levels to each fishโ€™s pictorial book: 0, 10, 30, and 90 growing up days in fish tanks.
    • When level 2, level 3 or level 4 fish are locked, the system automatically releases the low-level fish previously locked. You can only lock one fish, and you can double your points after collecting all level 4 fish, in all the colors, with the same suit.
    • The mined reward tokens are distributed according to the points and settled once a day. At the same time, the mining power is reduced by 4%. If the mining power is 0, then no more mining can be done.

    Front Endโ€‹

    Ecosystem Fitโ€‹

    Existing GameFi NFT projects mainly focus on the public chains, games and collectible publishing, Marketplace, etc. Popular projects working in this segment include Axie Infinity (NFT game), Chiliz (sports-oriented underlying public chain), Flow (general NFT issuance public chain), and Opensea (general marketplace). We will add more game functions than Axie Infinity and build on the Substrate framework. We also can collaborate with native Polkadot NFT marketplace RMRK and NFTMart.

    Resolvers networkโ€‹

    Although most payments can be processed on the LRP protocol, disputes are inevitable and they need to be resolved by humans. The estimated dispute rate of the traditional payment platforms is about 2%. A dispute occurs when buyer and seller cannot decide the outcome of the payment by themselves and the fund is still locked in the LRP protocol. We considered many of ideas and we believe the resolvers network is the best way to implement a decentralized dispute resolution.

    The dispute can be issued by the buyer and the seller can appeal the dispute. Both dispute and appeal action will need the fee estimated at $10 pay by Libraโ€™s token. A dispute will be resolved by a random resolver on the resolver's network. To become a resolver, a person needs to stake a required amount of Libraโ€™s token or create a candidate application and receive enough nominations from the community. 50% of the dispute fee is distributed to resolvers and the counterpart share to the nominators of the resolver.

    In the case that buyer or seller does not accept the final decision from the resolver, they will have 72 hours to decide to escalate the dispute or not. To request to escalate, they need to deposit $20 and the resolvers network will pick two more resolvers to re-investigate the dispute. After the investigation, the resolvers will vote for the final decision. If the final decision is different from the first resolver made, the first resolver will be slashed $20 to cover escalate fee and decrease the credibility. If the credibility is too low, the resolver will be banned permanently on the network.

    Unlike the already mentioned "Morph" platform ParaSpell focuses more on developers. ParaSpell features complete network install and startup configuration in one single command. This automatization ensures, that developers do not need to do any extra tasks when they wish to run development nodes locally. ParaSpell also allows developers to open and close HRMP channels between Parachains they connected. Like "Morph", ParaSpell can also transfer fungible tokens in three scenarios. From Parachains to Relay chain, from Relay chain to Parachains & from Parachains to Parachains.

    We are currently in talks with several Parachain teams that like the idea of unified SDK for XCM transfers as much as we do. SDK that unifies XCM can be very helpful for the entire ecosystem in our opinion. With the introduction of XCM API, this improves even further.

    Our target audiences are Web3 projects and starting/current blockchain developers.

    The new XCM-API is in development and we are currently searching for the fastest server with the lowest cost requirements.

    SDK is currently released into the main and is in a version that is fully operable. There are still some tweaks we plan to add and make, they are not part of this grant however. UI-V2 currently runs on state-of-the-art technology version VueJS 3 and the newest version of Nuxt. It deprecated V1 and introduced a much smoother interface and modules brought from the sub-scaffold template ParaSpell contributed to. Docs are currently in ready state but there is still some tweaking to do.

    Sidenote: We have recently developed an article about Polkadot & Paraspell called Enhancing XCMP Interoperability Across Polkadot Paraverse and it was accepted to the International IEEE BCCA 2023 conference held in Kuwait.

    Once everything will be implemented according to the proposed plan application will still be under constant improvement as technology will progress. For example, once the XCMP protocol will be released we wish to deprecate the HRMP protocol we currently use for channels.

    The project goal is that XCM-SDK & XCM-API will serve dApp developers and UI will teach new substrate developers to use XCM and will serve existing substrate developers to test their freshly baked Parachains.

    The newly added XCM-API will simplify XCM-SDK integration and will be much faster than integrating XCM-SDK into dAPP directly. Both repositories will remain dependent on each other. Further maintenance funding for servers and keeping XCM API up to date will be requested from Polkadot treasury.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    This project deliver a bridge relay to connect Polkadot and other PoW chains(Ethereum specific in this proposal). The bridge relay can provide an non-interactive, succinct proof of POW of a bridged chain based on ULVP (ultra-light verification protocol) . And based on such proof, it can further verify inner state of certain account or transaction inclusion proof.

    Project Descriptionโ€‹

    • MAP-Bridge would implement a new data structure called merkle mountain range(MMR) which contain the information of all confirmed block headers. And the root of MMR would be include in the new mined block somewhere.
    • In order to achieve this, we have to include the most recently MMR root in the new mined blocks in both Ethereum and Map bridge(parachain in Polkadot). For MAP bridge we can simply include it in the block header. For Ethereum, we have three possible way: firstly we could propose a EIP to ensure block header of Ethereum including MMR root; secondly we could deployed a contract in Ethereum to maintain most recent MMR root; and the last choice is to use CHT root in Ethereum instead of MMR root to do the verification work. In our proposal, we prefer to use the second method.
    • MAP-Bridge is build on a verification module called Ultra-Light Verification Protocol (ULVP). ULVP origins from the paper "Flyclient: Super-Light Clients for Cryptocurrencies". Any node could verify the existence of any transaction or the balance of any account with very limited data through ULVP compare to SPV.
    • The verification mechanism is as following:
    • The verifier connects some randomly selected full node in the destiny chain (at least one of these must be honest) and request them sending their tail blocks and corresponding proofs. Then the verifier validates the proof with the longest tail block. If it is a valid proof, the verifier would select this tail block as his choice and save it for next step. Otherwise he would drop this full node and check the second-longest tail block. The verifier continues this steps until it finds the tail block with valid proof. Based on our assumption, he connects at least one honest prover. Thus this algorithm would eventually find the honest longest tail block.
    • The verifier connects some other randomly selected full node in the destiny chain and obtains the block header in specified height and the corresponding MMR branch proof of this header upon to the most recent MMR. The verifier has the root of the most recent MMR which include in the tail block header. He could then validate the MMR branch proof based on it. If he get the valid block header he can save it for next step, otherwise keep doing it for another full node.
    • This step is similar to SPV. The verifier connects some other randomly selected full node in the destiny chain. The he could request them sending the detail of the transaction in specified height with the merkle branch proof up to the transaction root in block header( for state of any account is similar since the state root is stored in the header too). After that he could check the validity of the merkle proof. If the check passed, he could be sure that this transaction is indeed included in the destiny chain. If not, he could try another full node. If none of them could provide valid proof, he would know this transaction is not included in the destiny chain yet.
    • More details of ULVP could be found Here.

    Milestone 1 Implement Substrate MMR Moduleโ€‹

    • Estimated Duration:1 month
    • FTE: 3
    • Costs: 1 BTC In this milestone, we will build Substrate-based MMR for MAP bridge and also provide the MMR proof generating and verifying method in runtime module . This is a preliminary for ULVP module which can verify the validity of tail block of a certain blockchain carry heaviest proof of work. Furthermore, we will implement the block header storage functionality. This would make the blockchain could manage the MMR๏ผˆsuch as appending new blocks into blockchain and retrieving the MMR based on the MMR root in a certain block header, etc. ๏ผ‰.

    Milestone 2 Integrate ULVP module into substrateโ€‹

    • Estimated Duration: 2 month
    • FTE: 3
    • Costs: $1BTC In this milestone, we will further implement the ULVP module and some add-on module. This would involving generating and verifying succinct proof, specifying the cross-chain transaction, implementing the cross-chain transaction pool, building P2P network based on libp2p. Once this milestone is accomplished, the whole feature of ULVP module is complete and could be used to verify inner state of certain account or transaction inclusion proof for other blockchain.

    1.ULVP moduleImplement ULVP module to retrieve the transaction or state from another blockchain. We will realize all the three verification steps we mention above using the Substrate MMR module we finished in milestone 1.
    2.P2P Relay Substrate moduleImplement P2P Relay Substrate module which provide the functionality which could discover ethereum nodes and connect any ethereum node if the peer manager is not full. Once the connection has established, it use gossip to broadcast MAP parachain block announcement and cross chain transactions to ethereum, and receive message from ethereum. which contains ethereum block announcement, cross transactions, MMR Proof and Receipt Proof.
    3.Cross-chain asset transfer demoRealized a demo to enable token transfer between Polkadot parachain(MAP bridge) and Ethereum testnet. This need first deployed a contract in Ethereum testnet which maintain the MMR root of Ethereum. Next we need to deployed a mint contract in bridge parachain and a lock contract in Ethereum. If user lock some token in Ethereum to the lock contract, any node in the bridge parachain could verify this lock transaction. And the mint contract would mint the token in parachain if the lock transaction is indeed confirmed in Ethereum testnet.

    Future Plansโ€‹

    We plan to extend our bridge to most POW and POS type blockchains in the future. Through our bridge we could link more and more other blockchain systems into Polkadot Ecosystem .

    Project Detailsโ€‹

    Following the specifications of MACI as linked above, here is an overview of the architecture and core functionalities of Maki.

    Maki is a smart contract that allow its users to vote while making collusion among participant difficult (if the operator is honest) and retain censorship resistance, correct execution and anonymity of votes.

    Maki has two kind of users: one operator and 0..n voter(s) (also called user here under).

    The operator role is to deploy the contract (and publish his public key, known by all), start the sign-up period (which is done when the contract is deployed), process all the voters commands, generate the result of each commands, tally the votes and generate a zk-SNARK proof that the result is valid.

    The voter role is to sign-up for a vote and then vote.

    Secrecy of the votes are possible by using cryptographic operations. As described in the MACI specs, each users and the coordinator have a key-pair used to publish encrypted messages and for the coordinator to decrypt those messages.

    Overview :โ€‹

    Maki's Functions :โ€‹

    signUp allows a user to register for voting by sending his public key to the contract. There is no need for a given user to call this function multiple times.

    publishMessage allows a user to vote. A voter may use this multiple time to change his vote options, as long as the vote in not ended.

    processMessages function called by the coordinator to process all the users' messages, update the state root and provide a zk-snark proof.

    proveVoteTally to publish the vote result and the zk-snark proof of it. Called by the coordinator. Can only be called once the vote ended.

    verifyVoteTally to verify that the generated zkSnark proof is valid.

    Public functions are needed for the coordinator to process the votes off-chain (basically the contract's state such as stateTree, messageTree, etc.) and the voter to get the coordinator's key.

    Besides the contract, we will provide two circuits to build the zk-Snark proof off-chain, one for the correctness of message processing (proveStateCorrectness) and one for the vote tallying (proveVoteTallyCorrectness). The circuits will be written in circom and it will be used through a script that build and execute the compiled circuit. This is needed for the coordinator's functions processMessages and proveVoteTally.

    Maki has two merkle roots, one for the messageTree (which gathers submitted messages) and one for the stateTree (which gathers the mapping between the user public keys and the votes).

    Maki will be implemented as an ink! smart contract, so it will be developed in Rust with ink! library.

    Maki will not provide out-of-the-box choices of circuits used for zk-SNARK proof (as it may vary depending on the nature of the voting system), nor choices of the type of voting mechanism (non-quadratic votes, conviction votes, different tallying (such as what can be found on Polkadot and Kusama referenda), etc.). However this could be part of a maintenance program, a future plan, and/or another team may develop these features to meet their needs.

    The goal being to have a functioning contract, the circuit is not my main concern here.Therefore, an existing circuit will be reused (in Typescript) - most likely one that is implemented by MACI. I'll give full credits to their implementation, even if this requires some adaptations on my end.

    Ecosystem Fitโ€‹

    Maki can be used in any blockchain that supports ink! smart contracts.

    It can be reused - as provided or modified - by any blockchain, dApp, infrastructures, ... that wishes to provide a way to make quadratic votes for its users.

    I'm not aware of any similar project on Substrate. Despite that there are different existing voting mechanisms on Polkadot/Kusama, this one is the only one that would provide a quadratic, provable, anonymous and anti-collusion voting system.

    MangoBOX Protocol

    • Team Name: MangoBOX labs
    • Payment Address: 0x33e69715988126eB3653bFAfd338320BE9A10cd0(USDC))
    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    MangoBOX is a fork and upgrade of fund-raising protocol Juicebox on Ethereum. It rewrites the logic and functions of Juicebox in the smart contract language of Ink! and allows the ecological projects in Polkadot to raise funds from their community and introduce the Juicebox treasury management model into the Polkadot ecosystem. Anyone can utilize the MangoBOX platform to freely create a project fundraising page, customize the funding structure, customize how the project allocates funds and reward community members with tokens.

    Overviewโ€‹

    • If the name of your project is not descriptive, a tag line (one sentence summary).

    The Ethereum fundraising protocol Juicebox is the fundraising platform of the famous DAO organizations ConstitutionDAO and AssangeDAO, while the MangoBOX Protocol is a fork and upgrade of Juicebox. We introduce Juicebox into the Polkadot ecosystem and rewrite the logic and functions of Juicebox in the smart contract language of Ink!. MangoBOX allows all types of projects in the Polkadot ecosystem to raise funds from the community. Anyone can utilize the MangoBOX platform to freely create a project fundraising page, customize the funding structure, customize how the project allocates funds and reward community members with tokens.

    • A brief description of your project.

    Through MangoBOX, anyone or any organization can configure and deploy Ink! smart contracts with no need for coding and ultimately achieve the project's fund-raising and token allocation.

    Through MangoBOX, each payment made to the project by the community users will mint and allocate the project's Tokens to payers, and allocate a certain percentage of Token (retention rate) to a set of addresses preset by the project owner. The total number of Token minted for payment will be affected by the allocation discount rate. All funds received by a project will be considered as premium if it exceeds the funding target. These funds will become the community vault. Every Token holder can choose to how to allocate these capital premiums by redeeming(burning) their tokens.

    Projects crowdfunded on MangoBOX can configure Token distribution in multiple ways. For example a project with 0% discount rate, 10% redemption bonding curve, 10% retention rate and 1000DOT financing target is completely different from a project with 20% discount rate, 100% redemption bonding curve, 50% retention rate and 500DOT financing target. There can be many interesting configurations in these gradients, and there is no way for the project sponsor to know in advanc e what the best model will be, that simply because the vision and goals of each project are different, and that there is no precedent or data for decision-making. Each project can experiment on its own and find what works best for its needs.

    The core function of MangoBOX is fund-raising which contains flexible financing, capital allocation and exit mechanisms. The beauty of MangoBOX is that it enables dynamic ownership to transfer between project providers and project funders. By funding a project, community members can obtain the project's original tokens and become the partial owner of the project. This enables community members to benefit from being involved in the project and encourages them to help the project succeed.

    On the smart contract platforms built on Polkadot para-chains via MangoBOX, every project provider can raise and use funds transparently which ultimately helps the project providers and funders build a stronger trustful relationship.

    Each of every contribution, redemption, withdrawal and deposit on MangoBOX is transparent. MangoBOX makes the source and whereabouts of funds very clear, and allows the community to assess the value and risk of the project. This complies with DAO requirements and represents the spirit of Web3, from community to community.

    • An indication of why your team is interested in creating this project.

    On November 11, 2021, a group of crypto enthusiasts launched the ConstitutionDAO, in a bid to raise funds through the DAO to buy the first printed version of the U.S. Constitution auctioned by Sotheby's. As of November 19, Constitution DAO raised $47 millions worth of ETH with over 17000 contributors. During the fundraising process of ConstitutionDAO, contributors contribute a certain amount of ETH and will be rewarded with the corresponding PEOPLE Token. By voting, Token decides the usage of the copy of the ConstitutionDAO, including its exhibition venue and method.

    On February 8, 2022, AssangeDAO, a decentralized autonomous organization aiming to rescue Assange, raised more than 17,000 ETH. Vtalik Buterin, the founder of Ethereum, participated in the donation.

    The two DAO organizations, ConstitutionDAO and AssangeDAO, have also become the two most popular DAO organizations in the past six months, triggering a wave of development in the entire DAO industry.

    However, how did these two DAO organizations raise tens of millions of dollars and manage these capital funds ? They both made the same choice: Juicebox.

    Indeed, AssangeDAO and ConstitutionDAO are both DAO organizations built on the Juicebox platform which is responsible for fundraising, fund management, community token issuance and incentives. The huge success of AssangeDAO and ConstitutionDAO also indirectly proves that Juicebox is a trusted DAO capital management tool.

    Juicebox is a programmable treasury built on the Ethereum mainnet and a governance-minimized protocol that provides community funding for individuals and projects. In the crypto world, independent artists, developers, DAOs, and general public products, need a simple, convenient, fast, and secure way to capture the value they create, generate reliable cash flow from it, and then share it back to the community. Juicebox is one such fund raising and management platform.

    Juicebox offers a brand new solution for DAO treasury management and arranges the funds and its usage by the project in advance, and then raises funds from the community. According to the current operation, Juicebox has attracted over 500 DAO organizations to raise funds, and there have emerged ConstitutionDAO and AssangeDAO that drew the attention of the entire crypto community. It is fair to say that the treasury management model of Juicebox has been proven to be a success to a certain extent. Hence, we hope to introduce Juicebox's product model into the Polkadot ecosystem and this is why the Ink! version of MangoBOX came into being.

    • An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama.

    We hope to introduce Juicebox's product model into the Polkadot ecosystem and now are building the brand new MangoBOX. We plan to utilize Ink! smart contracts to rewrite Juicebox's product functions and logic, and deploy the MangoBOX on all WASM supported para-chains on Polkdot and Kusama, to make all types of DAO organizations, independent artists, developers and more general public products achieve fund raising and management possible via MangoBOX.

    But meanwhile, MangoBOX is more than Juicbox's fork and duplicate. It has its own unique product logic which is an innovation and upgrade based on Juicebox's fundamental features. For example, the project provider of the Juicebox treasury has unlimited power to mint governance tokens, which poses a huge threat potential to the treasury of the entire community. Any unethical project provider can steal all the funds in the treasury through the unlimited token minting power. The MangoBOX product function can set a limit on the project provider's minting power, which greatly reduces the potential threat to the DAO treasury.

    Project Detailsโ€‹

    • Documents of the main functions possessed by the MangoBOX protocol
    NumberSubjectSpecification
    1.Deploy an NFT that represents ownership over a projectEach project within the MangoBOX protocol is represented as an ERC-721 NFT. Whoever is the owner of a project's NFT has access to [admin functionality]for that project within the protocol, which ultimately gives it control over the project's funds.
    2.Configure funding cycles for a projectFunding cycles define contractual constraints according to which the project will operate.
    3.Mint tokensBy default, a project starts with 0 tokens and mints them when its treasury receives contributions.A project can mint and distribute tokens on demand if its current funding cycle is configured to allow minting.
    4.Burn tokensAnyone can burn a project's tokens if the project's current funding cycle isn't configured to paused burning.
    5.Bring-your-own tokenA project can bring its own token, as long as it adheres to [IMBToken]and uses fixed point accounting with 18 decimals.
    6.SplitsA project can pre-program token distributions to splits. The destination of a split can be an Polkadot address, the project ID of another project's MangoBOX treasury .
    7.Protocol feeAll funds distributed by projects from their treasuries to destinations outside of the MangoBOX ecosystem (i.e. distributions that do not go to other MangoBOX treasuries) will incure a protocol fee.
    8.Custom treasury strategiesFunding cycles can be customized.
    9.Accept multiple tokensA project can specify any number of payment terminal contracts where it can receive funds denominated in various tokens. This allows projects to create distinct rules for accepting DOT, any ERC-20, or any asset in general.
    10.Forkability and migratabilityA project can migrate its treasury's controller to any other contract that adheres to [IMBController]. This allows a project to evolve into updated or custom treasury dynamics over time as it wishes.
    • Documents of configure funding cycles

    Funding cycles define contractual constraints according to which the project will operate.

    The following properties can be configured into a funding cycle:

    NumberSubjectSpecification
    1.Start timestampThe timestamp at which the funding cycle is considered active. Projects can configure the start time of their first funding cycle to be in the future, and can ensure reconfigurations don't take effect before a specified timestamp.Once a funding cycle ends, a new one automatically starts right away. If there's an approved reconfiguration queued to start at this time, it will be used. Otherwise, a copy of the rolled over funding cycle will be used.
    2.DurationHow long each funding cycle lasts (specified in seconds). All funding cycle properties are unchangeable while the cycle is in progress. In other words, any proposed reconfigurations can only take effect during the subsequent cycle.A cycle with no duration lasts indefinitely, and reconfigurations can start a new funding cycle with the proposed changes right away.
    3.Distribution limitThe amount of funds that can be distributed out from the project's treasury during a funding cycle. The project owner can pre-program a list of addresses to split distributions between. Treasury funds in excess of the distribution limit is considered overflow, which can serve as runway or be reclaimed by token holders who redeem their tokens.
    4.Overflow allowanceThe amount of treasury funds that the project owner can distribute on-demand.This allowance does not reset per-funding cycle. Instead, it lasts until the project owner explicitly proposes a reconfiguration with a new allowance.
    5.WeightA number used to determine how many project tokens should be minted and transferred when payments are received during the funding cycle. In other words, weight is the exchange rate between the project token and a currency during that funding cycle.
    6.Discount rateThe percent to automatically decrease the subsequent cycle's weight from the current cycle's weight.The discount rate is not applied during funding cycles where the weight is explicitly reconfigured.
    7.BallotA common implementation is to force reconfigurations to be submitted at least X days before the end of the current funding cycle, giving the community foresight into any misconfigurations or abuses of power before they take effect.
    8.Reserved rateThe percentage of newly minted tokens that a project wishes to withhold for custom distributions.
    9.Redemption rateThe percentage of a project's treasury funds that can be reclaimed by community members by redeeming the project's tokens during the funding cycle.A rate of 100% suggests a linear proportion, meaning X% of treasury overflow can be reclaimed by redeeming X% of the token supply.
    10.Ballot redemption rateA project can specify a custom redemption rate that only applies when a proposed reconfiguration is waiting to take effect.This can be used to automatically allow for more favorable redemption rates during times of potential change.
    11.Pause payments,distributions, redemptions and burnProjects can pause various bits of its treasury's functionality on a per-funding cycle basis. These functions are unpaused by default.
    12.Hold feesBy default,MangoBOX membership fees are paid automatically when funds are distributed out of the ecosystem from a project's treasury. During funding cycles configured to hold fees, this fee amount is set aside instead of being immediately processed.
    • Contract Architecture of the MangoBOX protocol

    The MangoBOX protocol is made up of 7 core contracts and 3 surface contracts.

    • Core contracts store all the independent components that make the protocol work.

    • Surface contracts glue core contracts together and manage funds. Anyone can write new surface contracts for projects to use.

    NumberSubjectSpecification
    1.MBTokenStoreManages token minting and burning for all projects.
    2.MBFundingCycleStoreManages funding cycle configurations and scheduling.
    3.MBProjectsManages and tracks ownership over projects, which are represented as ERC-721 tokens.The protocol uses this to enforce permissions needed to access several project-oriented transactions.
    4.MBSplitsStoreStores information about how arbitrary distributions should be split. The surface contracts currently use these to split up payout distributions and reserved token distributions.
    5.MBPricesManages and normalizes price feeds of various currencies.
    6.MBOperatorStoreStores operator permissions for all addresses. Addresses can give permissions to any other address to take specific indexed actions on their behalf, while confining the permissions to an arbitrary number of domain namespaces.
    7.MBDirectoryKeeps a reference of which terminal contracts each project is currently accepting funds through, and which controller contract is managing each project's tokens and funding cycles.
    8.MBControllerStitches together funding cycles and project tokens, allowing for restricted control, accounting, and token management.
    9.MBPayoutRedemptionPaymentTerminalManages all inflows of funds into the ecosystem.
    10.MBSingleTokenPaymentTerminalStoreManages accounting data on behalf of payment terminals that manage balances of only one token type.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

    Under the leadership of Web3 and Parity team, after five years of development, the Polkadot ecosystem has entered a formal auction era for parachains, and more and more parachains have entered the operational stage, making Polkadot ecosystem flourish. Meanwhile, it has also entered into a new stage of development which is in great demand for applications on every para-chain to make the whole ecosystem truly prosper and create a Web3 world.

    In the world of web3, decentralized governance and transparent fund management are the most basic requirements of ecology, which are also the requirements for every ecological participant. When we saw the great success of ConstitutionDAO and AssangeDAO, we also saw the great value of juicebox. Therefore we created MangoBOX Protoco, using Ink! to reconstruct Juicebox's core logic and carry out some certain innovations and upgrades. We hope that when MangoBOX Protocol is fully created, it can serve various participants in the Polkadot ecosystem and provide a complete set of treasury management solutions.

    • Who is your target audience?

    Our main target audience are all types of DAO organizations, artists, DAPP development teams and public product developers. MangoBOX Protocol can provide fund-raising and capital management services for them.

    • What need(s) does your project meet?

    Whether it's for a project provider or a DAO organization, it is a complex and tedious process to create a treasury and issue tokens to community members and raise funds. The vast majority of the projects failed due to the lack of technical capabilities. MangoBOX system allows teams to configure and manage the whole fund-raising process with no need for coding, tackling the complexity of fund-raising from the community by the project providers.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    In the Substrate/Polkadot/Kusama ecosystem, we have not found any similar product. But there are some project in DAO's frame, such as subDAO and Dorafactory, that can provide some certain DAO infrastructure products and create all types of DAOs. Only MangoBOX has treasury management as its core function to raise and allocate funds transparently.

    Team's experienceโ€‹

    We are a Web3 start-up team from Beijing, China with Jason Zhao as our team leader and technical leader. Our team members come from different fields, from architects, product managers to full stack developers. Although we do not have a rich experience in Web3, our team has never been short of strong execution and high technical development capabilities. Our endless enthusiasm for Web3 led us to the start-up wave. As traditional Web2 practioners, our team has been engaged in the IT development in China for the last decade. As soon as Web3 opened a window to a brand new world, we immediately seized the opportunity.

    We found that the crypto industry holds endless opportunities like no other industry can match. The core vision of crypto and Web3 is to provide everyone with a native and open-source digital economy. Web3 is structured on the basis of blockchain, smart contracts and oracles, which holds a great potential to build a brand new and open ecology.

    Our team has been devoted to the R&D on the Ethereum ecosystem and not until 2021 when the Polkadot para-chains began to be deployed and applied that we had a better understanding of the ideas, principles and technology of the Polkadot ecosystem. We realized that whether it's from the top-tier ideas or the bottom technical structure, Polkadot represents the future and that's why we decided to commit to the build-up of the Polkadot ecosystem. Now as all para-chain on Polkadot are being operational, there is an emerging demand for DAPP's deployment and bulid-up, which is our unprecedented opportunity.

    Meanwhile, we found that no matter which ecology started to build, the DAO organization is the most active force in each ecology, and DAO is the future of the crypto world. In particular, the huge success of ConstituionDAO and AssangeDAO confirms our high recognition of DAOs. Hence, we decide to reconstruct Juicebox's functions and logic, using Ink! smart contract to build MangoBOX protocol, which is our first step to building up the Polkadot ecosystem.

    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile that can be used to test all the functionality delivered with this milestone.
    1.Ink๏ผContract:In the first milestone, we mainly implement how to create a fundraising project.It mainly consists of two parts, the first part is to create an NFT to represent the ownership and management of the project.Each project within the MangoBOX protocol is represented as an ERC-721 NFT. Whoever is the owner of a project's NFT has access to [admin functionality]for that project within the protocol, which ultimately gives it control over the project's funds.The second part is the basic rules for initializing this project. It mainly needs to set the following parameters:Start timestampใ€ Durationใ€Distribution limitใ€Overflow allowanceใ€Weightใ€Discount rateใ€Reserved rate, etc. Here we need to clarify that,the NFT we developed here is not a standard ERC721 token, it represents a management authority.What we are doing is a DAO fundraising system, anyone can build a DAO organization to raise funds. When this fundraising system is established, it is necessary to have administrative rights to configure parameters for this organization. At this time, we did not directly set the management rights from the code, but abstracted the management rights into an NFT. Whoever owns the NFT can control the DAO organization and adjust the corresponding fundraising parameters.Such a logical design can make the management authority of the DAO organization very easy to transfer, which is very convenient for the project party to manage the project.

    MangoSale Protocol

    • Team Name: MangoBOX labs
    • Payment Address: 0x33e69715988126eB3653bFAfd338320BE9A10cd0(USDC))
    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    https://github.com/w3f/Grant-Milestone-Delivery/pull/612

    Through the joint efforts of all team members, we have completed the development and submission of the first grant and also furthered our understanding of Polkadot ecology and the entire industry.

    MangoBOX labs is committed to the development of the DAO fundraising system, in the hope of developing a complete fundraising system. In the first stage, we developed an Ink! version smart contract of MangoBOX protocol based on Juicebox , which is a well-known project on Ethereum.

    However, in the actual process of development, we found some shortcomings of the Juicebox protocol as well : tokens can be issued additionally without restrain, the fundraising rounds are difficult to manage, and overall the protocol is relatively complicated to use. These characteristics are not conducive to the large-scale application of a Web3 product.

    After multiple rounds of research by our product team, we decided to conduct a more in-depth exploration in the field of DAO fundraising. We specialized in Ink! Smart contract version of MangoSale Protocol. MangoSale Protocol is a license-free protocol designated for project fair launch, which is considered as an open IDO platform. It is not limited to DAOs, but also applicable to various types of individuals or organizations. Compared to Juicebox, it's simpler and fairer to use. Any project party can raise the funds they want in different ways through the MangoSale Protocol.

    Overviewโ€‹

    • If the name of your project is not descriptive, a tag line (one sentence summary).

    MangoSale Protocol is based on Ink! A protocol developed by smart contracts that does not require permission and is used for the fair launch of projects belongs to an open IDO platform. Anyone, any community, and any organization can initiate token auctions and financing without permission, and carry out fair distribution of tokens.

    Based on Ink! version smart contracts, MangoSale Protocol is a permissionless , project fair launch oriented protocol that acts as an open IDO platform. Any individual, community or organization can start token auctions and financing without permission and implement token fair distribution.

    Well-known IDO platforms for inspiring MangoSale Protocol as below :

    โ€‹ 1. Pinksale๏ผš https://www.pinksale.finance/

    โ€‹ 2. Unicrypt: https://unicrypt.network/

    โ€‹ 3. Gempad: https://gempad.app/

    • A brief description of your project.

    As a permissionless fair distribution protocol, MangoSale Protocol is an open IDO platform which has the main following functions and features:

    • Permissionless and decentralized. Anyone can start the creation and auction of Token through the MangoSale Protocol and raise funds without any threshold or code base.

    • Multi-chain deployment. MangoSale Protocol will be deployed on multiple Ink! smart contracts supported para-chains in the future. The para-chain project owners can also deploy projects on their own.

    • Coexistence of multiple Web3 tools. MangoSale Protocol will provide at least three Web3 tools:

      1. MangoToken, Token factory can create Tokens with tax function.

      2. The MangoLock time lock function can lock up tokens in periods to realize the linear release of tokens.

      3. MangoAirdrop system. The airdrop system project owner can initiate airdrops for different users, which is conducive to expanding the group of currency holders.

    • Coexistence of multiple auction methods. MangoSale Protocol will support three different types of auctions to facilitate the launch of various natured projects, and the project initiators can choose freely according to their actual situation

      1. Launchpad: Token auction by a fixed price.

      2. Fair Launch: Token auction in the form of fair launch.

      3. Dutch Auction๏ผš Token auction in the form of Dutch Auction.

    • An indication of why your team is interested in creating this project.

    At present, there are more and more projects starting and financing in the encrypted world, and there also exist IDO platforms that provide services for various crypto projects. However, many IDO platforms are required to get permit, official review and KYC verifications from official authorities. This greatly hinders the scale of project initiation and sets various preconditions for the initiation of the project, making the process of project initiation tedious and difficult.

    In this context, MangoSale Protocol launched a permissionless IDO fair launch platform. Any individual, community or organization can start Token auctions and financing without permission and implement token fair distribution.

    At the same time, all smart contracts of MangoSale Protocol have been designed in advance. Anyone without code knowledge can complete the issuance and financing of tokens through a fixed template, which greatly simplifies the start-up process and enables all various projects to be completed as soon as possible.

    • An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama.

    With its continuous expansion and especially the steady progress of parachain auctions, the Polkadot ecosystem has entered a new stage. It no longer only focuses on the construction of the underlying technology, but also has entered the stage of ecological construction in an all-round way. At this time, various types of project owners are required to develop on different parachains. This is also an important reason why we are now developing MangoSale Protocol.

    We hope to develop a permissionless project launch and fundraising platform for the overall ecology of Substrate / Polkadot / Kusama, so that all types of projects in different stages can start on their own with the minimal costs and simplest steps and finally raise appropriate funds. This is our hope and vision today.

    Project Detailsโ€‹

    • Documents of the main functions possessed by the MangoSale Protocol

    1. MangoTokenFactory: TokenFactory can not only create standard ERC20 tokens, but also create ERC20 tokens with special functions, i.e, ERC20 tokens with tax functions. Taxation can be divided into different modules, such as marketing wallet and repurchase burning. Project owners can initialize the token factory according to their actual needs.

    2. MangoLock: The time lock function is also one of the core functions of the startup project. Through time lock, tokens can be locked in periods to implement the linear release of tokens, which can fully gain the trust of the community and make the project Token issuance mechanism more transparent.

    3. MangoAirdrop system: Project initiators can use the airdrop system to launch airdrops for different users in the ecosystem to motivate ecosystem contributors, which will help expand the number of coin holders and benefit more community members;

    4. launchpad: Launchpad: Launchpad auctions Token at a fixed price, which is one of the most common auction methods. Launchpad has a soft cap and a hard cap. If the soft cap is not reached, the auction will be cancelled. If the soft cap is reached, the auction will be successful. The maximum fundraising amount is the hard cap value. Token auction price is calculated according to the price set in advance, and the exchange rate is fixed.

    5. Fair Launch: Token auctions are conducted in the form of Fair Launch, and the auction price is not fixed. Fair Launch has only a soft cap, and there is no cap on the amount of funds raised. At the same time, the Token auction is not carried out according to a fixed exchange rate but according to the total amount of funds raised at the end of the auction. If the amount of funds raised reaches the soft cap and the fundraising is successful, the total amount of funds raised divided by the total number of tokens provided will be the user's actual purchase exchange rate. The higher the overall funds raised, the higher the user's purchase exchange rate will be.

    6. Dutch Auction: Token auctions are conducted in the form of Dutch auction. Dutch auction is a special auction method, also known as "reduced price auction". It refers to an auction in which the bids for the auction target decrease in order from high to low until the first bidder answers (reaches or exceeds the reserve price). Choosing such an auction method can make the auction fairer.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

    Under the leadership of Web3 and Parity team, after five years of development, the Polkadot ecosystem has entered a formal auction era for parachains, and more and more parachains have entered the operational stage, making Polkadot ecosystem flourish. Meanwhile, it has also entered into a new stage of development which is in great demand for applications on every para-chain to make the whole ecosystem truly prosper and create a Web3 world.

    In the world of web3, decentralized governance and transparent fund management are the most basic requirements of ecology, which are also the requirements for every ecological participant. We hope that when MangoSale Protocol is fully created, it can serve various participants in the Polkadot ecosystem and provide a complete set of treasury management solutions.

    • Who is your target audience?

    MangoSale Protocol can create and auction Tokens for different types of combinations and individuals without permission, and finally realize the fundraising.

    • What need(s) does your project meet?

    Whether it's for a project provider or a DAO organization, it is a complex and tedious process to create a treasury and issue tokens to community members and raise funds. The vast majority of the projects failed due to the lack of technical capabilities. MangoSale system allows teams to configure and manage the whole fund-raising process with no need for coding, tackling the complexity of fund-raising from the community by the project providers.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    In the Substrate/Polkadot/Kusama ecosystem, we have not found any similar product. But there are some project in DAO's frame, such as subDAO and Dorafactory, that can provide some certain DAO infrastructure products and create all types of DAOs.

    Team's experienceโ€‹

    We are a Web3 start-up team from Beijing, China with Jason Zhao as our team leader and technical leader. Our team members come from different fields, from architects, product managers to full stack developers. Although we do not have a rich experience in Web3, our team has never been short of strong execution and high technical development capabilities. Our endless enthusiasm for Web3 led us to the start-up wave. As traditional Web2 practioners, our team has been engaged in the IT development in China for the last decade. As soon as Web3 opened a window to a brand new world, we immediately seized the opportunity.

    We found that the crypto industry holds endless opportunities like no other industry can match. The core vision of crypto and Web3 is to provide everyone with a native and open-source digital economy. Web3 is structured on the basis of blockchain, smart contracts and oracles, which holds a great potential to build a brand new and open ecology.

    Our team has been devoted to the R&D on the Ethereum ecosystem and not until 2021 when the Polkadot para-chains began to be deployed and applied that we had a better understanding of the ideas, principles and technology of the Polkadot ecosystem. We realized that whether it's from the top-tier ideas or the bottom technical structure, Polkadot represents the future and that's why we decided to commit to the build-up of the Polkadot ecosystem. Now as all para-chain on Polkadot are being operational, there is an emerging demand for DAPP's deployment and bulid-up, which is our unprecedented opportunity.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 โ€” Implement the Core Parts of the Protocolโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0 / GPLv3 / MIT / Unlicense
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user, brand or third party application can interact with our protocol for the various specified use cases
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish a lite paper to describe the architecture and its implementation
    1.Build out the Pool ComponentWe will implement the Rewards Pool Component which contains the contracts, libraries and interfaces that describe and manage the sets of AMM pools for brand loyalty rewards. This component primarily consists of the pool contract, which manages all the logic relating to brand liquidity (swapping, adding, removing, multistage swapping, etc.), and the Pool initiator contract, which would create a pool every time a new brand reward is to be supported on our protocol. These are similar in concept to Uniswap Pool and Pool Deployer contracts, but with different requirements/implementation logic and no concentrated liquidity.
    Languages and framework: Ink!, Openbrush
    2.Build out the rewards factory componentWe will implement the Rewards Factory, which allows brands with or without Web3-based rewards to move some or all of their loyalty points to the blockchain using the PSP22 standard (and also PSP34/PSP1155 in the future). It contains the function for creating a new PSP22 token and keeping track of the associated brand.
    Languages and framework: Ink!, Openbrush
    3.Build out the Rewards Periphery ComponentWe will implement the Rewards Periphery Component that provides a form of incentivization to brands when their rewards are used to redeem offers across other brands. This component consist of two major contracts: Brand Bounty and Brand Treasury Contracts. Brand Treasuries are small fees paid by brand A to brand B when a customer from brand B chooses to redeem his/her reward with brand A. The treasury is a smart contract that holds these tokens, mapped to the appropriate brand. Brand bounties on the other hand are small amounts of reward tokens charged to a customer when he chooses to redeem that reward with another brand (typically swapping in our protocol). These small fees are stored in the Bounty Contract and when a bounty threshold is reached, they are issued as rewards to promote the issuing brand.
    Languages and framework: Ink!
    4.Build out the service payment componentWe will implement the Service Payment Component that brands and other integrating third-party applications will use to pay for the various services rendered to them through the protocol and business applications. This component consists of the payment/fee contract, which contains the logic to handle the reception of these tokens, mapped to the payer, and the logic to release these tokens when a paid service is rendered to the payer.
    Languages and framework: Ink!
    5.Build Out the Rewards Valuation Oracle ComponentWe will implement the Rewards Valuation Oracle Component, which helps to manage all external requests relating to rewards pricing and valuation in the protocol based on the supply and demand of these rewards in the pool. It consists primarily of the oracle contract that provides information on the valuation of rewards in our protocol.
    Languages and framework: Ink!

    Milestone 2 โ€” Adding the Protocol Peheripherals and Kickstarting the Frontend and Backend servicesโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0 / GPLv3 / MIT / Unlicense
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user, brand or third party application can interact with our protocol for the various specified use cases
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish a lite paper to describe the architecture and its implementation
    1.Build out the Protocol Access ComponentWe will implement the Access Component, which consists of contract routers that abstract the core protocol services and provide functions that brands, customers, protocol admins, and third-party applications can use to safely interact with the protocol. These are similar to the Uniswap router contracts, but instead of just one general contract, the contracts are split into Customer, Brand, Admin, and in the future Third-Party Contracts, based on the role of the requestor. A brand router, for example, will expose the functions that allow a brand to create a reward (using the reward factory), mint additional rewards or burn existing rewards, add or remove rewards from the liquidity pool, top up fee wallet, etc.
    Languages and framework: Ink!
    2.Build out the lens componentWe will implement the Lens Component that provides introspection into the protocol. This component is comprised of the Secretary and Loupe Modules. The Secretary Contract would provide business information like how many brands are connected to the protocol, total loyalty rewards in pools, etc. The Loupe Contract provides protocol architecture information, such as what functions the protocol supports and where these functions are deployed (it is an implementation of the EIP2535 DiamondLoupe Contract) etc.
    Languages and framework: Ink!
    3.Building out the Governance ComponentWe will implement the Governor Facet that will help to manage access control across the protocol and also help to manage governance rules for future proposals and updates.

    Melodot: Incentive-compatible data availability layer

    Project Overview ๐Ÿ“„โ€‹

    Data Availability Layerโ€‹

    The current data availability layer scheme requires the assumption that the network has at least the minimum number of honest nodes.However, due to the need to prevent data retention attacks, the samplers are required to be anonymous, making it difficult to measure the number of samplers. At the same time, samplers are more concerned with data related to themselves, resulting in an uneven distribution of total active samplers over time. The assumption of a minimum number of honest nodes affects the robustness of the data availability layer.

    Challenging issues in the data availability layer also include: who will perform distributed generation, who will reconstruct the data, who will store the data, how long will the data be stored, and how to ensure that these tasks are well done.

    One possible approach is to delegate these tasks to consensus validators, but there is a lack of effective incentive mechanisms. For cost considerations, not performing distributed generation, data reconstruction, and data storage is the most profitable for validators. In addition, consuming too many resources of consensus validators is very unfavorable for scalability.

    Melodot introduces the role of farmers by combining PoSpace, alleviating the system's dependence on the minimum number of honest nodes assumption, and completing an incentive-compatible distributed generation and data storage scheme. Consensus validators now act more like light clients, improving future scalability. You can learn more from this preliminary whitepaper.

    Project Detailsโ€‹

    Architectureโ€‹

    Erasure Coding and KZG Commitmentโ€‹

    Melodot uses 2D Reed-Solomon for data expansion, providing better sampling efficiency. It generates KZG commitments in the row direction, avoiding fraud proofs, similar to Ethereum's Darksharding. Block headers contain KZG commitments and data locations for different apps, allowing light clients to sample or download only data relevant to themselves.

    Farmersโ€‹

    Farmers receive rewards through PoSpace, which is used to verify that participants have allocated a certain amount of storage space on their devices. The consensus mechanism is achieved through a time-memory trade-off approach, which has its origins in the Beyond Hellman paper and has been adopted for use in the Chia protocol. This method allows for a more efficient and secure consensus process compared to traditional energy-intensive mechanisms such as Proof of Work. Subspace improves PoSpace for storing "useful data" and is closely linked to KZG commitments. We are inspired by them, in contrast, Melodot's farmers receive rewards through PoSpace rather than reaching consensus. This incentive mechanism ensures that the network can still recover data when natural sampling samples are insufficient and guarantees data storage for at least a specific duration.

    Farmers need to complete the distributed generation of specified data, expanding the data generated by block proposers in the column direction. They then calculate the challenge eligibility through the generated data, similar to Chia's filter, with only a small portion of farmers eligible to further search for solutions. This design reduces the computation load on farmers, avoids missing the submission of solutions, and allows farmers to devote more bandwidth and capacity resources to data availability sampling and storage. In addition, farmers are more inclined to generate all specified data in a distributed manner, as each chunk represents a potential lottery ticket.

    Farmers use the committed space to store blob data and maintain its timeliness. New data receives more rewards, while expired data will not be rewarded. Upon obtaining challenge eligibility, farmers need to search for solutions in the stored data, including chunk, data proofs, space proofs, etc. The system adjusts the difficulty based on the reward claims situation. Ultimately, the rewards farmers receive are linearly related to the size of the stored data space and depend on whether they have correctly and promptly completed distributed generation and necessary data reconstruction.

    Lifecycleโ€‹

    Untitled

    A complete blob transaction includes:

    • Publishing a blob transaction, including the original KZG commitment
    • Block builders collect blob transactions and build blocks, erasure code data, and generate new commitments to be added to the block header
    • Consensus validators verify block validity and, along with farmers, perform preliminary availability sampling (not ensuring 100% validity, but with high probability of being valid), either rejecting or accepting the block
    • Farmers use the block data, commitments, and proofs learned in the previous step to generate specified columns in a distributed manner
    • When the block is finalized
      • Farmers with challenge eligibility complete solutions and claim rewards
      • Light clients and consensus validators perform sampling simultaneously
      • Farmers obtain more specified data from the network for storage and delete expired data

    Melodot is developed in phases, with the first phase not implementing the complete process.

    Componentsโ€‹

    In this phase, we will implement the following core components:

    1. Erasure-Coding

      A core module for erasure coding and KZG based on rust-kzg, including expanding data and generating commitments and proofs, verifying blob, batch verifying blobs, recovering data, verifying the correct expansion of 2D commitments, and expanding column data and witnesses.

    2. Melo-Store

      Interfaces for registering and managing applications, uploading data, and storing data validity data.

    3. Consensus-related extensions

    excutive_das pallet: An extension of the frame-excutive pallet for scheduling block execution and validation related to DAS

    system_das pallet: An extension of the frame-system pallet, adding new block header generation, actual data generation, and validation.

    1. Sampling Core

    The core crate that actually performs sampling, which several clients in the system depend on. This includes data availability sampling, obtaining and propagating data from the DHT network, and managing data through rocksdb.

    1. Light Client

    A light client that connects to the network and performs sampling based on the block state, including network implementation, distributed generation, data storage, and actual sampling.

    1. Melo-PoSpace

    A pallet for assigning distributed generation columns to farmers, verifying farmers' challenge chunk, and issuing rewards.

    1. Farmer Client

    Connects to the network, obtains raw data, and performs distributed generation; obtains challenges from the chain and searches for solutions to claim rewards.

    Non-Goalsโ€‹

    The goal of the first phase is to minimally implement a usable system and will not fully implement the details described in the whitepaper. The main differences are:

    PoSpace

    In the first phase, we will only implement a preliminary version of PoSpace, not including the complete PoSpace process. Subspace has done an excellent exploration in this regard. In the next phase of development, we should be able to reuse much of their work.

    Complete Distributed Generation

    This phase does not include complete distributed generation. Users still need to submit actual data transactions, so farmers and validators do not need to perform the first phase of sampling.

    Ecosystem Fitโ€‹

    Similar Projectsโ€‹

    There are currently several data availability layer projects, including Ethereum Danksharding, Celestia, Avail, and Eigen DA. Our main difference from them is the introduction of farmers, which solves many tricky problems faced by the data availability layer. Unlike Danksharding, we decouple an independent data availability layer, which is the same principle as Polkadot not supporting smart contracts. Celestia uses a Merkle encoding pattern, requiring fraud proofs and additional assumptions, which we avoid. Avail's data layout uses a 1.5D scheme, which is unacceptable in terms of sampling efficiency, as detailed in the Melodot white paper. Eigen DA is an Ethereum re-collateralization layer implementation of a data availability scheme, with limited public information available, but it should be in the form of a DA committee, which has its applicable scenarios, but is not the same as Melodot.

    Relationship with Polkadot and substrateโ€‹

    1. With Melodot as a data availability layer, any parallel chain can easily become a Rollup settlement layer. Polkadot brings more secure interactions between settlement layers, significantly increasing Polkadot's capacity.
    2. Other teams can develop their own data availability layers based on Melodot.

    Development Statusโ€‹

    ZeroDAO previously developed the Ourspace project, which is a reputation system utilizing social relationships and received support from W3F. After that, we shifted our focus to calculating all social networks in Web3. In this process, we found that they were either expensive to interact with or difficult to securely use on-chain. Through in-depth analysis, we summarized these issues as a lack of visibility. Therefore, we temporarily paused the development of Ourspace (we will continue to develop it later) and focused on researching the "visibility" issue, discovering that rollup technology is a good solution to this problem. The data availability layer is the first step in achieving this, and after extensive research, we designed Melodot. The work we have completed so far includes:

    1. Whitepaper: Completed a preliminary whitepaper.
    2. Research: We conducted some research on Rollup and data availability layer projects, and you can see the project list here.

    TokenRemain includes the token frozen in the protocol of the underwriters who are able to underwrite for new policies, as well as the token of those underwriters who have stopped underwriting for new policies.

    โ€‹It can be seen that the value of ฮท decreases further, and the number of sTokens - representing the weight of capturing premium rewards, while bearing liability - that can be obtained for an equal amount of Tokens for underwriters joining the pool thereafter is increased . This is clearly due to the reduction in the actual underwriting capacity of the original underwriters following the erosion of the principal in the pool.

    4.3 Underwritten Assets Withdrawal Mechanismโ€‹

    4.3.1 Available Assets that can be Withdrawn by Underwritersโ€‹

    Underwriters can withdraw a portion of their unfrozen capital at any time before it is completely frozen. However, the frozen part needs to wait for the corresponding policy expiration to exit. The assets that can be withdrawn by the underwriter is calculated by the formula:

    โ€‹shadow is the amount of assets of the underwriters that has been frozen. However, the situation becomes more complicated when considering a policy that has expired which results in releasing part of frozen capital.

    4.3.2 Cancellation of Policiesโ€‹

    Along with the cancellation of policies which expire, the corresponding underwritersโ€™ frozen capital should be released. When a policy is generated, we record its lastProviderIndex and ฮ”accSPS. When it is cancelled, the protocol synchronises the latestUnfrozenIndex to the lastProviderIndex of this policy, and accumulates accSPSDown:

    โ€‹When calculating an underwriter's shadow, it is necessary to first determine the relationship between his index and latestUnfrozenIndex. When index<=latestUnfrozenIndex, it means that the capital being released already has the part of the underwriterโ€™s frozen capital. His shadow will be calculated by:

    4.3.3 After Underwriter Withdrawal of Assetsโ€‹

    In order to make the protocol easier to maintain and to reduce the cost of gas fee when users invoke the contract, Meta Defender currently requires the underwriter who would like to quit to withdraw all remaining liquidity at once (i.e., withdraw mentioned above).

    Of course, you may only want to "withdraw partially". It is very simple to implement this - you could simply withdraw in full and then re-join with your desired coverage amount. This saves the protocol from having to maintain a huge ledger, where the cost of gas would otherwise become unimaginable.

    When an underwriter withdraws assets, he or she needs to destroy all of his or her sToken.

    Suppose an underwriter P destroys all of his sToken, declaring that he has ended his status as an underwriter. Regardless of how much capital he has actually withdrawn (usually less than his original provided capital, i.e. ฮท*sTokenAmount, less than ), he can no longer continue to capture premium and no longer underwrite new policies, i.e., no longer "capture" new shadow.

    The protocol creates a "historical identity" for him, P', and records the following parameters:

    fsToken(frozen_sToken): the number of Tokens that this underwriter has not withdrawn, which will be then converted to sToken according to current ฮท;

    accSPS_P: the accSPS of P when it quits the protocol;

    index: the index inherited from P;

    sTokenAmount_P : the sTokenAmount inherited from P;

    SDebt_P: the sDebt inherited from P.

    It can be seen that the maximum amount that can eventually be released by P' is:

    ฮทโˆ—fsTokenโ€‹ ------ โ‘ ;

    The shadow inherited by P' from P is:

    sTokenAmount_P*accSPS_P - SDebt_P

    Or

    sTokenAmount_P*๏ผˆaccSPS_P - accSPSDown๏ผ‰------- โ‘ก;

    Obviously, at this point โ‘ก>=โ‘ .

    Thereafter, the Meta Defender protocol monitors for changes in โ‘ก. As the earlier policies gradually expire and are cancelled as well as the capital is unfrozen, the value of โ‘ก gradually decreases (of course, the relationship between index and latestUnfrozenIndex is taken into account, and โ‘ก is really reduced when index <= latestUnfrozenIndex.

    When โ‘ก < โ‘ , the difference between โ‘  and โ‘ก is the capital of P being unfrozen. P extracts it, updates the value of โ‘  to โ‘ก, and waits for the next unfrozen part.

    As accSPSDown increases, the value of โ‘ก eventually goes to zero. Zero is the minimum value of โ‘ก and cannot be a negative number.

    After โ‘  goes to zero, all residual capital of P finishes withdrawing.

    4.4 Leveraged Liquidity Mining Rewards Mechanismโ€‹

    The holder of sToken, i.e. the underwriter of Meta Defender, is entitled to the Leveraged Liquidity Mining rewards.

    In order to encourage underwriters to provide long-term, stable capital, sToken holders are required to hold their sTokens for a certain period of time (approximately 14 natural days, with minor variations depending on the speed of block creation on the mainnet) before they can participate in the withdrawal of this Rewards.

    After withdrawing from the Capital Reserve and destroying the sToken, the holder will lose the eligibility to withdraw the proceeds. The mining proceeds will be hosted separately by Meta Defender's governance contract and will be claimed from the pool for sToken.

    Ecosystem Fitโ€‹

    Meta Defender will use the stablecoin in parachains as the currency for buying cover, underwriting and for payouts of claims. Currently Meta Defender is planned to be deployed with ink! Smart contract and compatible with Substrate and XCM. Ultimately, we would like to provide insurance services to the main parachains and major protocols in the Polkadot Ecosystem. Also, by introducing XCM, we would like to achieve cross-chain insurance.

    Our Leveraged Mining component will cooperate with top liquidity mining protocols in Polkadot Eco, which will increase the TVL of those projects.

    We are planning to integrate the Blockchain Oracles function in the Polkadot Ecosystem๏ผŒe.g. Phala, which will expand our insured subject-matters to more off-chain scenarios.

    Our target audience will be the users who would like to buy covers for their digital assets in the Polkadot Ecosystem, as well as those who would like to utilise their idle capital to become an underwriter and gain proceeds from Liquidity Mining in the Polkadot Ecosystem and rewards from our insurance protocol.

    As the rapid development of Defi markets, asset holders are looking for an insurance protocol that can protect them when emergencies like theft, cyber attack and data leakage happen. Meta Defender is designed for providing such services.

    There is an insurance protocol called Nsure that received a grant from W3F. Meta Defender has following highlights compared to Nsure๏ผš

    Meta Defenderโ€™s pricing model is an upgraded Automated Market Maker Model purely based on the relations between supply and demand. Therefore, there is no need to manually adjust the factors for calculating the premium rates because it's auto-generated.

    Meta Defenderโ€™s Leveraged Mining will cooperate with Liquidity Mining protocols in the ecosystem while Nsure has their own capital mining pool. We believe, cooperating with top Liquidity Mining protocols in the ecosystem will maximise the returns with the capital that underwriters inject to the protocol.

    We are also planning to provide insurance service for more off-chain scenarios by integrating blockchain oracles, such as flight cancellation insurance.

Since these will be part of the agreement, it helps to describe the functionality we should expect in as much detail as possible, plus how we can verify and test that functionality. Whenever milestones are delivered, we refer to this document to ensure that everything has been delivered as expected.

    For each milestone,

    โšก If any of your deliverables is based on somebody else's work, make sure you work and publish under the terms of the license of the respective project and that you highlight this fact in your milestone documentation and in the source code if applicable! Teams that submit others' work without attributing it will be immediately terminated.

    Milestone 1 - Create and manage multisig callsโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can create a multisig. The steps should be self explanatory for anyone having basic multisig knowledges.
    0c.Testing GuideThe scope of this project being too small, no testing will be done in a first step.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone..
    0e.ArticleWe will publish an article that explains the basics of multisigs and show the benefits of using this interface to create more complex multisigs.
    1.creation screenUsers will be able to create a multisig based on a list of signatories and a threashold.
    2.indexerTo provide a smooth user experience, a subsquid indexer will make sure to track multisig interractions. The Docker will be made available
    3.home screenThe home screen will allow to select the available multisig and see the signatories, the threshold along any pending request
    4.request approvalUpon reviewing pending approvals, users are able to approve pending approvals and submit the final extrinsic without any external communication with other signatories.
    5.pallet supportThe multisig will be based on the [mutlisig](https://github.com/paritytech/substrate/tree/master/frame/multisig) pallet, also using [proxy](https://github.com/paritytech/substrate/tree/master/frame/proxy) and [utility](https://github.com/paritytech/substrate/tree/master/frame/utility) pallets to handle the different flows.
    6.stackBoth front-end and back-end are using Typescript. The front-end is built using React, it will connect to a blockchain node for live information such as the pending proposals, and to user wallets such as Polkadot-js extension to allow users to sign extrinsics. The backend is made of a subsquid indexer that is tracking multisig interractions.

    Future Plansโ€‹

    As mentioned above, this is requesting the funding to get things started with a functionnal UI, wihout too many bells and whisles. Many needs have already been identified for institutions and DAOs. Chainsafe is dedicated to make this the stepping stone of a long road. Other features such as the flow to rotate signatories, make more complex extrinsics from the UI or add some proxies to the multisig can be added at next steps.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Introductionโ€‹

    NFTStore is an exclusive public chain for managing NFT assets. Users can not only issue their own NFTs, but also trade NFT transactions. The project is developed based on substrate 2.0. In the first phase of the design, we will write the business code at the runtime level. The project actually needs to consider whether to introduce the contract layer. In the economic model, we will fully give the token holders the transaction income on the platform Store. NFT is one of the important ways for the application of blockchain technology to approach life off-chain. We hope that this public chain will provide more possibilities for real-world assets on the chain. In addition, there are members of the team who have rich e-commerce experience. I believe that NFTStore has become the amazon.com of the blockchain and the best trading platform for digital assets in the world.

    Project Detailsโ€‹

    Architectureโ€‹

    NFTStore based on Substrate 2.0 and the Polkadot. Contains NFTStore node, pallet_nft, pallet_store and Front End.

    img

    • NFTStore Node is the customized chain node built by Substrate 2.0 .

    • pallet_nft is used to create and manage NFT assets.

    • pallet_store is responsible for NFT sales.

    • Front End provides Web UI for everyone to interact with the NFTStore. Front End will be built with React.

    • NFTStore Token $NFTT is the native token of the NFTStore, and it will play the role of governance and other utilities. $NFTT is necessary to secure and power the chain.

    Data Structureโ€‹

    Milestone 2 โ€” Checked Migration Processโ€‹

    We will write up the โ€˜Checked Migrationโ€™ process which includes a security protocol to ensure that both the sender and the receiver are satisfied with the migration outcome. This is especially important if NFT's are migrating from/to a trustless universe (eg : a public decentralized blockchain) toward/from a centralized/private universe. This process is NOT a fully decentralized trustless process itself in order to accomodate for a wide array of possible origin and destinations, but it does allow decentralized trustless outcomes while guaranteeing authenticity and ownership of the NFT at every step.

    The main purpose of this migration process is for NFT publishers to allow their users to effortlessly migrate their tokens with the least amount of efforts required. NFT publishers could offer users to do the whole migration with a single gas spending approve() from an NFT owner and the rest trough meta-transactions by the publisher. The publisher would then sign the migration as properly done after having minted and transferred the token on the destination blockchain. By essence, most NFTs are not trustless assets as their publishers own real world IP rights to them, and it is hence acceptable to use said publishers as relayers. This is standardizing a process that would otherwise require the publisher to update their original NFT smart contracts or NFT owners to burn their original NFT token in order to get a new one minted on the destination universe.

    Milestone 3 โ€” Trustless Migration Processโ€‹

    We will write up the โ€˜Trustless Migrationโ€™ process which is designed to be used when the destination universe have trutsless state reading capabilities of the origin universe.

    Milestone 4 โ€” Standard and Documentation for Cross-universe Migrationโ€‹

    We will write up the standard and documentation for cross-universe migration, which includes โ€œnecessaryโ€ and โ€œoptionalโ€ data for optimization. This is a summarized write up of both the previous milestones but writen as specifications for implementations, including the predicate and postulate of each message and what they mean in term of state on the source and destination universe.

    Future Plansโ€‹

    We will implement this standard for EVM-compatible chains. Our main goal is the ability for any Ethereum mainnet NFT to be painlessly migrated to Moonbeam on the Polkadot network.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Our project NuLink is trying to bridge the NuCypher Network to the Polkadot Ecosystem. The NuCypher Network is a decentralized network of nodes that perform threshold cryptography operations serving users with secrets management and dynamic access control; in particular, NuCypher currently offers a threshold proxy re-encryption solution that enables secure data sharing which can be used to construct content management platforms, secure messaging, encrypted NFTs, and many other applications.

    Through our project, users and applications from Polkadot could take advantage of NuCypher Network. For example, a user Alice in Polkadot could share her private data to another user Bob using the integration from our project, without worrying information leaking to any third party, thanks to NuCypher cryptographic assurance.

    The main components of the project are:

    1. A Nuproxy pallet which can retrieve the information of stakers and bonding workers from NuCypher contracts in Ethereum to Polkadot parachain;
    2. A Policy pallet which holds policy fees and distributes them to nodes of the network.

    Project Descriptionโ€‹

    • In the NuCypher Network, all the cryptography operations are currently performed in an off-chain side channel. We can reuse this side channel in our project. We only need to take care of the on-chain operation from Ethereum to Polkadot. The on-chain operation mainly includes two parts: Stakers need to register and get rewards on-chain, while Alice needs to grant access to Bob and pay fees to stakers on-chain. NuLink would focus on migrating the on-chain operation from Ethereum to the Polkadot parachain.
    • We will develop a Nuproxy pallet which can retrieve the information of stakers and bonding workers from Nucypher contracts in Ethereum. At the current stage we consider constructing a watcher network managed by the NuCypher team. The watcher network would relay such information to the Nuproxy pallet.
    • The watcher network is simply constructed by a single watcher node in the current version. The Nuproxy pallet would check the signature of the watcher node to pass the update request. And in the future we would expand the watcher network to a multi-signature network constructed by a certain number(say N) of watcher nodes. And their corresponding public key would be recorded in the Nuproxy pallet when first deployed. The update request must obtain more than the 2/3 signature of the total watcher nodes to be valid. The Nuproxy pallet would check the signature when receiving the update request. The locking period of Ursulas network is 1days, so the watcher network would send the update request at the same pace.
    • In the future we may use ETH-Polkadot bridge such as Snowbridge to retrieve such information from Ethereum instead of the watcher network. The details would be updated once we finish the design.
    • We would also develop a Policy pallet which can hold policy fees and distribute them in the Polkadot parachain. Through this pallet, Alice in Polkadot could issue a policy in the polkadot parachain and pay the policy fee in the Polkadot parachain. And the worker of Ursulas could withdraw the reward in the Polkadot parachain.

    Additional Information โž•โ€‹

    We have discussed this project with the NuCypher core team and got some technical support from the NuCypher team.

    We have implemented the watcher nodes independently and not funded by this proposal. The owner who deployed the Nuproxy pallet could either manually update the information from Ethereum, or use our watcher node updating it automatically. Here is the (link)the watcher nodes.

    Update & Amendmentsโ€‹

    2022/02/27โ€‹

    We underestimated the total work and the time-line has now been exceeded by several months. We have already submitted our work and are waiting for review.

    This amendment updates the name of the mirror pallet to the Nuproxy pallet, and the name of the Policy Management pallet to Policy pallet.

    We have decided to implement the watcher network as one single node in the current version. And we will keep working on this and support the multi-nodes network in the future.

    • Compared to the formal on-chain votes, this platform provides not so formal off-chain signed polls which may help token holders and community members engage more in the ecosystem building.
    • Compared to Polkassembly polls on post:
      • users have to sign their votes and the signed data will be stored on IPFS
      • users donโ€™t have to do any registration.
      • Different strategies can also be provided to calculate the final result, rather than simply count the vote numbers.
    • Not all on-chain systems with assets on Substrate based chains can upgrade with democracy, like assets issued on Statemine, ERC-20 assets which may be issued on Moonriver, Karura, Shiden, etc.

    Project Detailsโ€‹

    Off-chain votes will be an important part of OpenSquare collaboration platform. Other planned collaboration forms include bounties, payment QA, short term employment, etc. Key components in this proposal include:

    • Predefined spaces where users can create proposals. It will definitely include Kusama and Polkadot, current para-chains with very high possibility.
    • Proposal list in one space where users can view the closed or ongoing proposals.
    • Proposal detail page where users can view the detail and the signed votes.
    • A proposal discussion arena where users submit the signed messages and here we expect chaos.
    • An authoring page where users can create proposals, and set the corresponding snapshot height, start and end date(height).
    • Archive nodes interaction with which we read usersโ€™ balances on the corresponding snapshot block height.
    • A backed server to interact with the node(Polkadot, Kusama, etc), store the organized data to DB, handle IPFS storage, provide APIs to get data.

    os_grant_voting

    Some implementation notes:

    • We have to call polkadot.js extension to sign the voting/poll, and some discussion messages.
    • About voting power, since Polkadot/Kusama have proxy accounts, so we have to support proxy account vote on behalf of the original one.
    • In this proposal, we will implement balance of account and quadratic balance of account strategies for Polkadot and Kusama. It means if Alice's balance is 100 at one chain height, her voting power will be 100 and 10 by these 2 strategies.
    • We have a partnership with Crust, and we may store data to IPFS through decoo that crust granted.

    Ecosystem Fitโ€‹

    • Providing off-chain voting/polls to help token holders/community members engage more in ecosystem building.
    • Flexible strategies help produce different voting/poll results which bring us different opinions from the on-chain tallying methods.
    • snapshot is popular for Ethereum stack projects, mainly for governance, and currently we didn't see similar projects in Polkadot ecosystem.

    We have more than 3 years experience with Substrate/Polkadot related tech stack. Our recently developing products include:

    • doTreasury. We can now see it as a treasury business explorer but it aims to improve the treasury mechanism with retrospection.
    • Statescan, a fungible asset explorer for Statemint implementation chains.
    • OpenSquare bounties business built on substrate. We got a grant for this, and please check details here.

    We are honored that either dotreasury or statescan get support from kusama or polkadot treasury, and our work about bounties is granted by w3f previously. We are confident to deliver a high quality and usable off-chain voting site.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Only 1 milestone in this proposal, while the main goal is to check the feasibility of off-chain voting in the polkadot ecosystem. We will put more features like more plugins and strategies in future proposals, but after this proposal we will launch it and make it available to the community.

    Milestone 1 โ€” Implement Basic off-chain voting/polls logic for Polkadot & Kusama

    • Estimated duration: 2 weeks
    • FTE: 3
    • Costs: 8,000 USD
    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.CodeCode will be open source, organized in one monorepo by yarn workspaces, hosted on OpenSquare github account. It will be implemented in JavaScript, React for fronted, koa for backend. Either fronted and backed will depend on polkadot.js, while fronted will also depend on extension-dapp to interact with polkadot{.js} extension.
    0c.DocumentationWe will provide a documentation site to explain necessary concepts, how this site work, and some user workflows.
    0d.Test casesCore functions will be covered by unit tests to ensure functionality and robustness. They will could be verified in simple npm scripts.
    1.User story 1Alice opens OpenSquare.io(domain not finally decided) and she can see spaces at least include polkadot and kusama. She can see a closed and ongoing proposal list after clicking a space.
    2.User story 2Alice will see the proposal description, votes records and the final result or analysis/distribution on a closed proposal page.
    3.User story 3Alice votes yes on an ongoing proposal with polkadot{.js} extension, she can see her vote and re-vote to override the previous one. The reason that she changed her vote is that she checked the discussion and found some related news.
    4.User story 4Alice created a proposal with the title โ€œShould there be a specified UI for the society features?โ€ and some description, and there are 2 choices: yes and no. She chose the voter balance as the final result strategy, while she can also choose sqrt balance as the strategy. With a very high sumed balance vote yes to Aliceโ€™s proposal, she now is very confident to seek more support to go on with following actions.
    5.User story 5Bob wanted to create a proposal at kusama height 1000, but failed, because his account has 0 balance. Anybody can create a proposal, but the minimum requirement is having at least 10 KSM at the target height.

    Future Plansโ€‹

    • Add more spaces, and in the future users may create their own space and customize it.
    • Support plugins and more strategies so users can customize the process and voting result.
    • Support voting by assets issued on statemine or erc-20 tokens.

    Architecture ๐Ÿ—โ€‹

    Diagram

    Application is purposely designed to be as simple as possible. This guarantees, that all tasks can be done quickly and without extended searching. All necessary screens also feature notifications which will as a milestone explain be callback reactive. The loading screen is only present on the first application & network startup, once accessing the same screen after the application was loaded it will be skipped automatically. The screen serves to register necessary assets in parachain nodes. This is only required to be run once per network startup.

    Technology Stack ๐Ÿ’ปโ€‹

    Ecosystem Fit ๐ŸŒฟโ€‹

    There are not many XCM & XCMP related development tools released currently. We aim to aid this mostly empty space and help developers to understand XCM & XCMP as the current state-of-the-art technology by providing documentation and a user interface in which they can do development tasks more easily and faster.

    In Polkadot and Kusama ecosystem, there are few XCM & XCMP related Dapps in development. These rather focus on standard users mostly. One of mentioned type is called "Morph".

    Unlike the already mentioned "Morph" platform ParaSpell focuses more on developers. ParaSpell features complete network install and startup configuration in one single command. This automatization ensures, that developers do not need to do any extra tasks when they wish to run development nodes locally. ParaSpell also allows developers to open and close HRMP channels between Parachains they connected. Like "Morph", ParaSpell can also transfer fungible tokens in three scenarios. From Parachains to Relay chain, from Relay chain to Parachains & from Parachains to Parachains.

    Our target audiences can be Web3 projects & starting/current blockchain developers.

    Once everything will be implemented according to the proposed plan application will still be under constant improvement as technology will progress. For example, once the XCMP protocol will be released we wish to deprecate the HRMP protocol we currently use for channels.

    In a long run, we also want to improve design, add new features that can be useful for developers, support for new nodes, and ability to add a new node from the user interface.

    UI that uses XCM SDK has it's functionality implemented already which was main goal of our first proposal. We will shift it towards new version of Vue which is state of the art during fufillment of this proposal. SDK has beta pre-release phase released, it features all 29 nodes that implement xTokens pallet, ability to transfer to & from Relay chains, ability to open & close HRMP channels.

    0b.DocumentationWe will provide both inline documentation of the code and a usage explanation in readme.md
    0c.Testing and Testing GuideSDK Core UNIT tests will be provided for xTokens Pallet, HRMP pallet, polkadotXCM pallet
    0d.DockerDocker file that allows to test ParaSpell SDK through ParaSpell UI will be provided.
    1.Create scaffold template for Web3 projectsCreate template on Git for Web3 dApps to allow users to start developing and deploying in just minutes, this template will contain different libraries important for Web3 development already preinstalled. Languages planned to be used are Typescript. Stack that will be used is Vue3 (Nuxt 3), pnpm package manager, Polkadot API libraries (Use KodaDot packages if applicable), ParaSpell SDK, UI will consist of basic components (address input (checks if address entered is valid), ballance input (no longer necessity to input lenghty amounts, will have sum conversions) etc.. ), wallet management (PolkadotJS, Talisman, Subwallet), all other not mentioned libraries will be mentioned in readme of template and readme will be linked to delivery.
    2.Implement support for checking asset compatibility through asset palletEach node, that has ability to check which tokens it supports should be automatically queried for this data and SDK should be able to determine compatibility based on data queried.
    3.aAdd support for nodes without xTokens pallet IWe will implement support for transfer scenario Parachain to Relay chain for nodes that do not have xTokens pallet but have polkadotXCM prebuilt template pallet. (SDK will be able to determine which pallet to use on which Parachain automatically)
    3.bAdd support for nodes without xTokens pallet IIWe will implement support for transfer scenario Parachain to Parachain for nodes that do not have xTokens pallet but have polkadotXCM prebuilt template pallet. (SDK will be able to determine which pallet to use on which Parachain automatically)
    4.Make SDK easier to useMerge Parachain to Parachain & Parachain to Relay chain scenarios in SDK into one scenario that will be able to adapt based on details provided (if destination node id not provided, then assume transfer is for relay chain, also if token is compatible with relay chain), this will replace need for calling two functions for each scenario with only one function covering both scenarios eg. send() instead paratopara() & paratorelay()

    1.Add support for checking data that does not changeThere are things that do not change, such as base token configuration (Polkadot, DOT token, 10 decimals), (Astar, ASTR, 18 decimals) This can be imported from @polkadot/network library to have better support for different transfer scenarios
    2.Rewrite SDK to builder patternBest thing we can do to support multiple pallets and make it simplier for developers would be a Builder pattern functionality would look like: import { Builder } as โ€˜@paraspell/sdkโ€™ and then building of call would be something in sence: const call = Builder(api).from(โ€˜bsxโ€™).to(โ€˜ksmโ€™).teleportTokens(โ€˜KSMโ€™).addr('destinationAddr').sum(currencySum).asV3().build()
    3.Make a map of compatible <chain, pallet>Before each SDK release there should be a script that connects to the compatible nodes, checks all relevant available pallets xTokens, polkadotXCM, asset pallets, HRMP pallets) and saves them to the map.

    NumberDeliverableSpecification
    0LicenseApache 2.0
    1.aSubstrate module: Loans palletLoans pallet will be implemented as a multi-assets lending protocol which offers lending and borrowing by using floating rate model. The full expected functionality is described here (โ…ข-1, โ…ข-2).
    1.bSubstrate module: Liquidation palletWe will implement a liquidation solution build with Substrate Off-chain Worker, which will calculate the health factor of each borrower's account and send a liquidation transaction automatically. The full expected functionality is described here (โ…ข-4.1).
    1.cSubstrate module: Price aggregation oracleWe will need to create an on-chain price aggregation pallet for the oracle prices from multiple sources that is queried by off-chain workers. The full expected functionality is described here (โ…ข-5).
    2.aIntegration with front-endWe will integrate our existing front end to the finalized substrate backend.
    2.bArticle/TutorialWe will create an article and a demo video that will explain how users can start using the platform for lending and borrowing DOT or KSM tokens.
    3.DockerWe will provide a dockerfile to demonstrate the lending functionality.
    4.Testing and DocumentationWhile we develop our module, we will ensure that our code has significant test coverage (>80%) to ensure quality and provide explanations on how the functions work for the community to review, as well as craft test guides.
    5.User TestingWe will conduct user testing to improve our product's UI and UX, to ensure that the borrowing and lending functionalities are intuitive. Initially, we will conduct qualitative user testing by observing 10-15 users who will use the v1 platform and provide a summary of the findings and improvements made based on insights.

    This is an application for a follow-up grant for providing POOL STAKING in "Plus:Polkadot js Plus Extension".

    polkadot{.js} plus extension intro

    Overviewโ€‹

    Polkadot js plus extension, or for short Plus, is actually the original Polkadot js extension, plus some new features. It is a user-friendly wallet to interact with the Polkadot/Substrate based blockchains/parachains through a browser. It allows users to access their account(s), which can also be used to interact with decentralized apps.

    We don't want to rebuild the wheel, we just want to perfect it, standing on the shoulders of giants like "polkadot js extension" and make it user-friendlier for users. The reason why we have decided to work on this project is every day user comments on social medias that complain "why the extension does not show the balance?", "It is too complicated for new/average users to work with", "It is too abstract", " why should we go to another web site to work with the extension?", " how could contribute to the crowdloans via extension?", and so on. Hence we started to work on the Plus extension to address such concerns/requests of the Polkadot community. Plus is based on Polkadot js extension, and get constantly updating with it. Both extensions can be run simultaneously, but with Plus you do not need to install the original extension, because Plus does whatever the original extension does even more.

    At the currant state our extension has the following features available:

    • Viewing balances (crypto/USD)
    • Transfering funds
    • Transaction history
    • Viewing an address as QR code
    • (Solo) staking
    • Crowdloans
    • Governance

    Recently, Parity Technologies staking team released a new pallet, named "Nominations pools", which will make pool staking available on Kusama, and Polkadot. Now, it is available on Westend, will be available on relay chains soon. Therefore, we have decided to be among the first to provide this new coming functionality for Dotsama community on Polkadot js plus extension.

    Project Detailsโ€‹

    With the new functionality the stakers on Kusama/Polkadot will have two options to stake their tokens, hence when click on easy staking in Polkadot js plus extension, solo or pool staking can be chosen.

    polkadot{.js} plus extension accounts

    polkadot{.js} plus extension staking index

    With Pool staking, stakers (delegators) with a small amount of tokens (e.g., 1 DOT) can pool their funds together and act as a single nominator. The earnings of the pool are split pro rata to a delegator's stake in the bonded pool.

    Ther following features will be available in pool staking:

    • auto vs manual staking (pool creation, join, nomination,etc.)
    • unstaking (unbonding, claim payout, redeem)
    • view own pool information (including pool name, Id, state, members Info, roles, and their accounts, reward/stash Id, and pool destroying)
    • view nominations (including selected validators information, its nominators, actives, oversubscribeds, and ability to re-nominate)
    • viewing pool staking general information (e.g., minimum to join/create, max pools, etc.)

    Where a delegator can easily contribute in pool staking automatically, and confirm it by entering the account password:

    polkadot{.js} plus extension pool stake

    polkadot{.js} plus extension pool stake confirm

    Similarly unstaking can be done, where unlocking bonds will be redeemable after a while depending on the chain:

    polkadot{.js} plus extension pool unstake confirm

    Pools information along with its roles and accounts can be presented in pooltab:

    polkadot{.js} plus extension pool staking pool tab

    The account(s) with root and nominator role can nominated validators for the deligated stashId, the nominated validators can be depicted in the nominations tab:

    polkadot{.js} plus extension pool staking nominations tab

    The general information that every staker/deligators needs to know can be summarized in info tab:

    polkadot{.js} plus extension pool staking info tab

    There would be also modules for manual pool selection/creation, manual validator selection, pool details information including pool's members' information, etc.

    Ecosystem Fitโ€‹

    Plus extension will be a user-friendly wallet to interact with the Polkadot/Substrate based blockchains through a browser. It allows users to access their Polkadot account(s), which can also be used to interact with decentralized apps. It is based on the original polkadot js extension, which injects a @polkadot/api signer into a page, along with any associated accounts.

    The difference with polkadot.js extensionโ€‹

    Polkadot.js extension is an official account management tool, but Plus extension will be not only an account management tool but also implements a series of common functions in Polkadot ecology, such as fund transfer, transaction histrory (including, send, recieve, bond, nominate, bond_extra, redeem, etc), easy staking, easy-to-operate on-chain governance modules, contribute to crowdloans, etc. This means that polkadot js plus can not only do what original extension does, but also independently complete the above mentioned functions, providing users with a one-stop experience, which polkadot.js extension does not have.

    From the perspective of UI experience, polkadot js plus tries to not just be more user-userfriendlier but also consistent with the previous taste of the users, who are already familiar with the original polkadot js extension. We try to make the UI more attractive to users, and also support all the languages that are currently existd on the original extension.

    Product direction and advantagesโ€‹

    Analogous to MetaMask, browser extension wallets are convenient to interact with DApps. Plus is positioned as a browser extension wallet and has a first-mover advantage in the product direction. It focuses on the Polkadot ecosystem and enables more users to participate in the Polkadot ecosystem through customized and truly friendly interactive experience.

    This is a proposal for the RFP titled Social Recovery Wallet, and in other words a follow-up grant for providing Social Recovey in "Plus:Polkadot js Plus Extension"

    polkadot{.js} plus extension intro

    Overviewโ€‹

    Polkadot js plus is Polkadot js extension, plus new features. It is a user-friendly wallet to interact with the Polkadot/Substrate based blockchains through a browser. It allows users to access their account(s), which can also be used to interact with decentralized apps.

    We don't want to rebuild the wheel, we just want to perfect it, standing on the shoulders of giants like "polkadot js extension" and make it user-friendlier for users.

Both extensions can be run simultaneously, but with Plus you do not need to install the original extension, because Plus does whatever the original extension does even more.

    At the currant state our extension has the following features available:

    • Viewing balances (crypto/USD)
    • Connecting to different endpoints
    • Transfering funds
    • Viewing transaction history
    • Viewing an address as QR code
    • Staking (Solo and Pool)
    • Crowdloans
    • Governance

    Based on the Social Recovery Wallet RFP, proposed by David Hawig from W3F, we have decided to provide this feature in the Polkadot js Plus extension.

    Project Detailsโ€‹

    With the new functionality the token holders will be able to make their accounts Recoverable. Almost all required information will be saved on-chain, utilizing Substrate/Recovery-Pallet.

    polkadot{.js} plus extension make recoverable

    and when you open the accounts page, a green shield icon indicates which account is already recoverable.

    polkadot{.js} plus extension recoverable icon

    Ther following features will be available as Social recovery wallet:

    • making an account recoverable
    • let users find their lost account Id using their on-chain identity (name, twitter, riot id, etc)
    • removing recovery from an account
    • initiating recovery for a lost account by a rescuer
    • showing an alert for a lost account, for which the recovery is initiated
    • let a lost account to close recovery and punish a malicious rescuer by gathering its deposit
    • let on-chain friends to vouche for their friend's lost account
    • let a rescuer account to claim recovery and set itself as a proxy of the lost account

    After an account holder determined their friends and set recovery delay and threshold, can make the account recoverable by confirming it using the account password:

    polkadot{.js} plus extension confirm making recoverable

    Similarly the user can remove recovery for a recoverable account using remove recovery tab:

    polkadot{.js} plus extension remove recovery

    To rescue a lost account, we have two identities, a rescuer and the lost account's friends, who can help to rescue the lost account:

    polkadot{.js} plus extension rescue tab

    A rescuer should start by intiating the recovery process, but usually when you lost your account you hardly remember the acount Id, hence, it should be possible to find the lost account using it's on-chain identity:

    polkadot{.js} plus extension iniTiate recovery

    When a malicious rescuer initiates the recovery for a lost account, we need to set an alert for the lost account, as can be seen below as a beating red shield .

    polkadot{.js} plus extension red alert

    Therfore, the lost account can close the recovery to protect their account.

    polkadot{.js} plus extension close recovery

    There would be also modules for friends to send their vouches, enabling claim recovery by a rescuer, modules for canceling recovery, taking over the lost account (as recovered), and etc. Finally, in a successful recovery attempt, the rescuer account will act as a proxy of the lost account.

    Ecosystem Fitโ€‹

    Plus extension will be a user-friendly wallet to interact with the Polkadot/Substrate based blockchains through a browser. It allows users to access their Polkadot account(s), which can also be used to interact with decentralized apps. It is based on the original polkadot js extension, which injects a @polkadot/api signer into a page, along with any associated accounts. The social recovery feature is definitely a blockchain requirement and can stop the nightmare for many normal (non-technical) end users.

    The difference with polkadot.js extensionโ€‹

    Polkadot.js extension is an official account management tool, but Plus extension will be not only an account management tool but also implements a series of common functions in Polkadot ecology, such as fund transfer, transaction histrory (including, send, recieve, bond, nominate, bond_extra, redeem, etc), easy staking, easy-to-operate on-chain governance modules, contribute to crowdloans, etc. This means that polkadot js plus can not only do what original extension does, but also independently complete the above mentioned functions, providing users with a one-stop experience, which polkadot.js extension does not have.

It is based on the original polkadot js extension, which injects a @polkadot/api signer into a page, along with any associated accounts.

    Competitive product analysisโ€‹

    Polkadot's browser extension wallet, the currently known competitors are Enzyme, Speckle OS, and Doter.

    Enzyme and Speckle OS have very limited features and not been maintained for a long time over a year. Dotter also has very limitted capabilities, so that the functional modules achieved by Plus extension's first milestone have exceeded Doter (Recently, we have completed the first milestone), and more functional modules that will serve the Polkadot ecology will be implemented in the plan.

    The difference with polkadot.js extensionโ€‹

    Polkadot.js extension is an official account management tool, but Plus extension will be not only an account management tool but also implements a series of common functions in Polkadot ecology, such as fund transfer, transaction histrory (including, send, recieve, bond, nominate, bond_extra, redeem, etc), easy staking, easy-to-operate on-chain governance modules, contribute to crowdloans, etc. This means that polkadot js plus can not only do what original extension does, but also independently complete the above mentioned functions, providing users with a one-stop experience, which polkadot.js extension does not have.

    From the perspective of UI experience, polkadot js plus tries to not just be more user-userfriendlier but also consistent with the previous taste of the users, who are already familiar with the original polkadot js extension.

It focuses on the Polkadot ecosystem and enables more users to participate in the Polkadot ecosystem through customized and truly friendly interactive experience.

    How to maintain the walletโ€‹

    In the near future, we will have someone in charge of maintaining the Plus extension, not only update it with the original polkadot js extension but also fix bugs, and even improve the experience๏ผŒto making Plus as close as possible to a mature browser extension in other ecosystems like MetaMask.

    Project Description ๐Ÿ“„โ€‹

    When user claim their DOTs, they need a native Polkadot address. Now, there are several ways to generate a Polkadot address. Polkadot.js and Polkadot.js browser plugin is less secure than using Subkey. Subkey is secure, but it is ecommended for technically advanced users who are comfortable with command line and compiling Rust code, it is not recommended for general users.

    PolkaKey planned to provide a secure and simple way to generate a Polkadot address for general and technically advanced users.

    PolkaKey is a desktop app build with Electron and can run on three platforms (MacOS, Windows, and Linux).

    PolkaKey can generate a Polkadot address without internet connection. In fact, we also recommend that users use it when disconnected from the network. It is secure than using Polkadot.js and Polkadot.js browser plugin.

    PolkaKey will bringing smooth UX to Polkadot, it is simple than subkey.

    PolkaKey is open source for full transparency, so anybody can audit.

    PolkaKey will never save any info locally, the private key is self-owned.

    to ask the user to sign such a magic string with injected signers and provides it as an access tokens for Applications. Instead of verified by authorization server who holds the approval of resource owner (user), it should be verified in a decentralized way.

    Project Detailsโ€‹

    Sign in Participantsโ€‹

    Workflowโ€‹

    The workflow works the same with or without OAuth specification. Only the 4th step will differ.

    1. A user sends a request to a service provider.
    2. The service provider sends a callback address, the sign-in challenge, and required permissions to the user.
    3. The user connects to the injected signer.
    4. injected signed to sign the challenge, and send the signature together with the public address, an access token specifying the scopes like expire time, back to the callback address. With OAuth Implementation, the access token is compliant with the OAuth standard.
    5. The service provider validates the signature, if successful, the user signed in,
    6. If there is no related user information in the database, the service provider will lookup for the user information from Identity Registrar, if related TEXT records are found for this address, the information will be imported into the service providerโ€™s database.

    Sign-in Flow

    Implementationโ€‹

    1. Sign-in Request

      User want to sign in the dApp by send a simple request with identity chain type, eg: DOT, KSM, ETH etc.

      The payload is required since each chain has its own algorithmic mechanism.

      request payload(1)

      {
          "identity-type": "dot"
      }

    2. Authentication Requirement

      dApp will return the callback info. The callback endpoint is used by Identity provider to send signature data to dApp.

      {
          "identity-type": "dot",
          "callback-endpoint": "http://dapp.com/login/callback",
          "scope": ["xxx", "yyy"],
          "chanllenge": xxxxxxxxxx",
      }

    3. Connect to Signer

      User sends request to the Identity Provider (Injected Signer like : Polkadot.js Extension, Metamask, Parity Signer ...).

      This action will call up a browser extension or some other external applications.

      {
          "identity-type": "dot",
          "callback-endpoint": "http://dapp.com/login/callback",
          "scope": ["xxx", "yyy"],
          "chanllenge": xxxxxxxxxx",
      }

    4. Provide Signature The Identity Provider will generate the Signature data.

      {
          "identity-type": "dot",
          "public-key": "xxxxxxxx",
          "account-signed": "xxxxxxxxxx",
          "scope": ["xxx", "yyy"],
      }

      explains:

      • identity-type

        This field is used to choose the chain type and account.

      • public-key

        With the chain account chosen, get the public key of the account. This field will be used by dApp to decrypt the data and verify data consistency.

      • account-signed

        use private key to sign the account.

        eg:

        account = 0x1016f75c54c607f082ae6b0881fac0abeda21781

        private-key = 18e14a7b6a307f426a94f8114701e7c8e774e7f9a47e2c2035db29a206321725
        account-signed = ECIES ( ${account} , ${private-key})

        # encrypt account with private-key by the specified algorithmic mechanism: ECIES

      • scope

        scope define the permission needed for the dapp to interact with the account.

      • chanllenge

        a text string need to be signed by the private key.

      The Identity Provider will send the signature data to the callback endpoint of dApp by step #3.

    5. Validation

      The dApp receives the signature data and do the verification.

      ```
      {
          "identity-type": "dot",
          "public-key": "xxxxxxxx",
          "account-signed": "xxxxxxxxxx",
          "scope": ["xxx", "yyy"],
      }
      ```

      Verification Steps:

      • use public-key to decrypt the data of account-signed , this progress should be successful, and get the account address.

        public-key pairs with private-key, this step proves the validity of the private key, and ensure that the data was not tampered with.

      • use public-key to generate the address by the specified algorithmic mechanism according to the chain type, and get the account address refer to public-key .

      • verify the two account address , success if they are the same.

      • if failure, it means the public key does not match the account address, it may happen when some malicious users want to impersonate an account.

      • if success, the dApp should return the response to the Identity Provider with the payload:

        {
            "verified": true,
            "access-token": "xxxxxx"  # generated by dApp as access token
        }

    6. Lookup Identity

      The dApp gets the account address . It can retrieve the related information of account from the external service providers , such as ENS, Polkadot/Kusama Identity Registrar, etc.

    Ecosystem Fitโ€‹

    There is few solution combine the OAuth and self-custody wallet, and no such solutions in the Polkadot ecosystem. With our solution and the ecosystem tools like polkadot.js extension and Parity Signer, the substrate account could be used to sign in any web2 or web3 platform which support OAuth, user also do not need to input all his information once registered in a new platform, the information could automatically be fetched from the info records in identity pallet, which could gain huge adoption of Substrate account in Web2 world.

    Overviewโ€‹

    Dart has advantages in native development.

    Dart is a computer programming language developed by Google, which is used in the development of web, server, mobile apps and the IoT. Dart is an object-oriented, class-defined, single-inheritance language. Dart is a general programming language developed by Google, which was later recognized as a standard by ECMA (ECMA-408). It is used to build web, server, desktop and mobile applications. Its syntax is similar to C language and can be translated into JavaScript, interfaces, mixins, abstract classes, reified generics, optional typing and sound type system .

    Dart is very positive for Polkadot. Currently Polkadot-JS (hereinafter referred to as JS API) provides developers with a complete JS API for interacting with the Polkadot. Both Web and App can call JS API. But the problem is that in App development and design, developers must provide a built-in browser interface on the front end, and then use JavaScript to implement JS API calls. The web is embedded in the app, which will cause the front-end page to load slowly, the development framework is not easy to maintain, and the native functions cannot be fully invoked.

    Flutter and Dart are born for cross-platform applications development. As Dart is using in the development of Flutter, we propose that using Dart language to develop tools for Polkadot/Substrate will be a better solution.

    As a new framework, there are not many blockchain SDKs suitable for Flutter. Ethereum provides web3dart, which is a relatively complete Dart implementation. It contains important features such as JSON RPC encapsulation, offline signature, ABI encoding and decoding, and its goal is to provide a dart version of web3.js, which can meet the needs of most Flutter applications to connect to the Ethereum blockchain.

    Similarly, we also found that there is currently no Polkadot SDK suitable for the development of the Flutter framework, although we have seen that some members of the community use Flutter/Dart to implement some wallets or some scattered tools, which is not a complete interactive implementation. For example, encoding and decoding, crypto standards, api design, etc., should all follow the design of Polkadot-JS and be completely migrated to the Dart language.

    Similar to polkaj (Java version), we will develop the Dart version and name it Polkadot-Dart.

    Project Detailsโ€‹

    To complete the porting, we follow the project structure of Polkadot-JS.

    There are some differences between Dart and Javascript, and the project needs to be compatible. For example, The "wasm" compiled by Rust-lang is used in Polkadot-JS . As for dart, we use dart:ffi for communication. All Rust-native libraries will be compiled to .so for Linux/Android system, .a or .framework for iOS/MacOS, and .dll for Windows.

    And for the extension packages, we must realize that it is only available for WebApp based on JavaScript browsers. As for Dart/Flutter, we have to find another way to interact with WebApp and have other solutions for JavaScript app/Dapp, please refer to Pocket4D WIKI .

    Therefore, we defined Dart project like Polkadot-JS .

    Polkadot Protocol Conformance Tests Research Proposal

    • Team Name: LimeChain
    • Payment Address: 15reUHgnkE9QeH9zUoduCVYAbksTmQXvpMd6L95rBhTNFuGw (USDT)
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    This research proposal is in response to the currently open Polkadot Protocol Conformance Tests RFP.

    Overviewโ€‹

    Polkadot has made substantial progress over the last few years in terms of client diversification. Currently, there are 4 existing host implementations with varying features and protocol support: Polkadot by Parity, Kagome by Soramitsu, Gossamer by ChainSafe, and Fruzhin by LimeChain. Having a healthy client diversity is beneficial to every blockchain protocol as it becomes more decentralised and less bug-prone. Neglecting these aspects has resulted in halting block production for some blockchain protocols in the past.

    The nature of software is such that it's never perfect, and bugs happen. Therefore, multiple host implementations come with a higher probability of implementation-specific issues. It's important for a blockchain protocol that takes great pride in its decentralisation, such as Polkadot, to have a protocol compliance testing suite that verifies the behaviour of each implementation. The more comprehensive the testing suite is, the stronger security guarantees the protocol can provide.

    The goal of this project is to prepare for the redesign of the existing conformance tests repository. Our team envisions the redesigned testing suite to be easily extensible and flexible, welcoming contributors to enhance it with their domain-specific knowledge. Concerns have been raised regarding the "adapter" approach that the existing testing suite has taken and that the chosen language (Julia) is out of sync with the one for Polkadot (Rust). This proposal aims to lay the groundwork for resolving these issues by delving deep into the biggest obstacle that stands in the way: finding the correct level of abstraction and tooling that will be the cornerstone for every kind of test scenario.

    Project Detailsโ€‹

    A host-agnostic approachโ€‹

    A conformance testing suite should be host-agnostic, meaning that, for the most part, the tests shouldn't be concerned with the specific Host implementation against which they are being executed. The Host exposes several interfaces that enable conformance testing; however, itโ€™s a complex piece of engineering, and there will always be protocols and functionalities without an exposed interface. Moreover, there are integration tests that can't be conducted using an API. These scenarios are as important as the previous ones because the Host can't function properly if the modules don't work seamlessly with one another.

    Host APIโ€‹

    The Host API consists of a set of functions that the Host exposes to the Runtime. These functions are used to access external resources for various purposes, including storage access, manipulation, memory allocation, and more. If a method within the API contains a bug, it has the potential to push the Host into an incorrect state transition. Such a scenario could lead to undefined consequences, particularly if a significant number of nodes experience the same issue.

    SCALEโ€‹

    Substrate employs a lightweight and efficient encoding and decoding mechanism to optimise the transmission and reception of data across the network. This protocol, known as the SCALE codec, plays a vital role in serialising and deserialising data. It serves as a critical component for data transfer across the peer network and facilitates communication between the Runtime and the Host. Consequently, the presence of comprehensive tests for SCALE encoding and decoding holds immense significance in ensuring the proper functionality of the Host.

    State Trieโ€‹

    The state trie is another crucial part of the Host. A radix-16 state is the data structure that Substrate uses to store the state of the blockchain. Without thoroughly tested state trie functionalities, the Host may transition to an incorrect state and get slashed if it's a block producer.

    BABE & GRANDPAโ€‹

    BABE & GRANDPA are the bread and butter of the consensus-reaching module for Polkadot. However, finding the right tools and approach to test the block production and finalisation protocols independently of the Hostโ€™s environment is a challenge that is yet to be overcome by any team.

    Zombienetโ€‹

    Zombienet aims to be a testing framework for Substrate-based blockchains, providing a CLI tool that allows users to spawn and test ephemeral networks. The assertions used in the tests can include on-chain storage, metrics, logs, and custom JavaScript scripts that interact with the chain

    Our team has successfully utilised Zombienet to run PVF conformance tests as part of another W3F grant. This is the reason why we believe that Zombienet has the potential to be the go-to framework for running conformance tests on the Hosts. The research is going to focus on Zombienet, as well as on the new Zombienet SDK.

    Research Scopeโ€‹

    The main focus of the research will be on investigating each of the aforementioned protocols and functionalities and how they can be tested in a host-agnostic manner. Based on our preliminary research and the work we've conducted on the PVF conformance testing suite, our team believes that Zombienet can serve as the foundation for the testing suite. The team will examine whether Hosts and Zombienet have the required feature set to support such testing scenarios. If this is not achievable, the team will document the missing components so that they can be identified and potentially contributed in a future proposal.

    Our team acknowledges that, for certain Hosts, having the Host API, SCALE, and State Trie as standalone artifacts could be beneficial for Host developers during the early phases of their implementation. However, this proposal primarily focuses on adopting a host-agnostic approach for Hosts that are already functioning with the already existing tests. Depending on the research outcomes, our team may subsequently introduce a new proposal involving the redesign of the conformance repository. In this redesign, the tests would be separated into a standalone artifact and transformed into Zombienet tests.

    Ecosystem Fitโ€‹

    By delivering a research document containing insightful information about the necessary steps to commence the redesign of the Polkadot Conformance Testing repository, we aim for it to serve as a catalyst to initiate the development process

    Initially, the Polkadot Conformance Testing repository will be situated in close proximity to the realm of Polkadot Hosts. Its primary target audience will be Host developers seeking comprehensive testing for their Hosts. Other individuals who might find this project valuable include experts from the Polkadot specification team, who can contribute their expertise in specific scenarios.

    Once MetaMask merged its Snap function to the normal version, BTCSnap (developed by Keystone) will be promoted as one of top 3 Snaps on its main page where our snaps would get a huge exposure. In a short term, we plan to develop a series of snaps for different chains and make a โ€œSnaps Bundleโ€ upon our Bitcoin Snap where users could easily switch to different snaps for different chains in one place. In the long term, weโ€™ll continue to build various snaps, not only for transactions, but also Defi, NFT, Game etc for different chains to enrich the Keystone Snaps ecosystem and obviously Polkadot will be one of our top priority.

    Milestone 3 โ€” Implement Verifiable Timeline UI for XCM Transfers and Messages [UMP, DMP, HRMP]โ€‹

    Similar to the above, in this milestone we develop tooling for XCM Transfers + Messages, which we believe to be central to the success of the Polkadot ecosystem. We propose to build an XCM Timeline UI with verifiability of XCM transmissions for the 3 "common" XCM protocols (DMP, UMP, HRMP) that are already widely between several dozen parachains. A prototype timeline can be seen here and is linked from the XCM Transfers page which shows all indexed XCM Transfer. This XCM Timeline UI and existing XCM Transfer Indexing will be backed by 3 core verification functions that we will develop:

    which each will verify that a extrinsic's XCM message(s) are routed through a relaychain / parachain specific to one of these 3 protocols. A simple verification process will involve verifying whether the XCM Message from a sending chain has the expected extrinsics/events/traces on receiving and downward chains.

    We will attempt to adapt our XCM Timeline tool to support XCM instructions that contain XCM messages (transferReserveAsset, depositReserveAsset, initiateReserveWithdraw, initiateTeleport) within that scope, thus potentially involving more than 2 chains.

    We will restrict our XCM timeline tool to DMP, UMP, and HRMP/XCMP and our restrict our scope to existing v2 and v3 messages.

    NumberDeliverableSpecification
    0A.LicenseGNUv3
    0B.DocumentationWe will provide: (a) inline documentation of the XCM Indexer and how the matching process between sending and receiving chains works for XCM Messages; (b) APIs for retrieving indexed XCM messages + transfers with XCM v2+v3
    0C.Testing GuideWe will augment the Google Doc Testing Guide to (a) explain how the XCM Timeline UI "Verify" functionality can be accessed and used to test each of the 3 XCM protocols in scope; (b) explain how recursive XCM messages within the same scope can be covered.
    1.UI Augmentation: XCM Messages VerifiabilityUsing the same approach as in Milestone 1 and 2, we will augment the Polkaholic.io with browser-based JS and server-side JS to support verifiability of XCM Results.
    2.Continuous TestingUsing server-side JS, continuous random checks on recent XCM Messages chain will be applied, outputting verification rates.
    3.Blog PostWe will publish a blog posts that demonstrate the Polkaholic.io XCM Messages and Transfers API and new Timeline functionality.

    We expect any observed failures in verification and the XCM Timeline tool to result in indexing fixes targeted at XCM specifically.

    Future Plansโ€‹

    Polkaholic.io intends to operate its multi-chain block explorer for Polkadot users long-term, as well as supporting parachain developers and dapp developers with XCM tooling and APIs that just work.

    Project Overview ๐Ÿ“„โ€‹

    Polkawatch is an Encode Hackaton Finalist project that received a runner up nomination. See 3 minutes final pitch video here.

    Overviewโ€‹

    Polkawatch tagline is: Polkadot's decentralization is everybody's job.

    Polkawatch will provide decentralization analytics about Polkadot. Allow all stake-holders to gain insights about where network activity is taking place (regional, network provider, validator group, nominator segment, etc).

    With Decentralization insights the community can act to improve decentralization regardless of their role: Adjust Nomination, Start Validation in new Networks / Geographies, etc.

    Polkawatch is built on top of Substrate Block Explorers (i.e. SubQuery) adding an extra analytic layer.

    Polkawatch crosses chain data with external datasources and traces weak on-chain relations. Initially for Polkadot, Polkawatch could be used for any substrate blockchain.

    Why Polkawatch? All started by helping a validator of the 1000 validator programme design a strategy to improve its share of network activity/election. We identified centralization as a problem and opportunity. As preliminary data shows more than 50% of activity in just 2 cloud providers and/or nations. Validators with poor network share could be the decentralized answer to this problem.

    Unavailability Slashing takes place if at least 10% of active validators go offline. There is precedent of swift deplatforming by cloud providers and sudden regulation change by Countries. Nominators need to be aware that supporting "too centralized" validators poses significant more risk than nomating validators in network and countries below the 10% threshold. It also makes our community stronger and more resilient.

    Project Detailsโ€‹

    Lucene inverted index is the core technology component of many Analytics Engines, Its capability to parallelize ingestion and query is unprecedented. This project has a clear functional scope but it is also an interesting experiment in term of building an Analytic Engine for a substrate blockchain.

    • The main data structure is a collection of fully "decorated" Reward events/documents. By "decorating" a reward we mean to add to the event everything we know by analyzing the blockchain, and crossing its data with external data sources. The collection of events is then indexed on a Lucece Inverted Index to facilitate its analytics.
    • The following mock-ups, based on unaudited polkawatch prototype data, show the target analytics to provide, distribution of network activity by: Geographic and Computing Network, Validator Group and Nominator Segment, Tables with broken down data and generic information about the dataset.
    • The following Architecture Diagram Shows the main Components:
      • Indexer: Will read and index the blockchain using a Lucene Inverted Index. The main Event to trace is the reward event. Will be decorated with all data that can be deduced from the blockchain crossed with external datasources: Geographic and Networking data.
      • Live Query Server: Will provide an API interface to the Indexed data, ready to be consumed by the DAPP and the DPP Publisher.
      • Distributed Data Pack Publisher: Will publich to IPFS Polkawatch Queries of general interest, those related to general network status. The Data Pack is presumed immutable for a given last processed block number, and must be "IPFS friendly", i.e. once an Era has been claimed completely its reward data should be inmutable.
      • DAPP: The DAPP will consume mainly the IPFS DPP, although it may also consume Substrate RPC to learn about the Network Status and Objects of User interest (Wallet). It could potentially also request advanced queries to the Live Query Server, although most queries are expected to be ready as a DPP.
    • The API to be provided by the Live Query server each entry point (Query) represents a set of filters and aggregations to apply to lucene queries. This component can be fairly generic, in the sense that each entrypoint can be mapped to a lucene query with the help of a templating engine.
    • The technology stack to be used will be Javascript/TrueScript for the Live Query Server and DPP publisher, React+Gatsby for the DAPP, Material UI for the UI components, Gitlab will be used for CI/CD, and IPFS/IPFS Cluster for publishing.
    • During the Hackaton Subquery and Elasticsearch were used as base components for the indexer. This choices will be re-visited after reviewing all indexers in the community and also other lucene databases such as Apache Solr.
    • What your project is not or will not provide or implement
      • This project will not create a Generic Indexer based on Lucene Inverted Index but rather extend, complement or fork an existing indexer in our community.
      • This project will not provide a generic staking dashboard or wallet, but rather focus on the analytics, grand view and support the decision making related to the nomination and validation activities.

    Ecosystem Fitโ€‹

    Polkawatch will use a blockchain indexer, modify or extend it for a particular analytic use case, based on Lucene inverted index. This project may be of interest to decide if inverted indexes or analytic capabilities should be built into indexers in a more generic way.

    The Polkadot ecosystem needs effective decentralization and polkawatch can help. The community is already debating about this, and visibility of network activity will enrich the debate.

    This project sits next to blockchain explorers, but its output will be graphic, analytic instead of detailed transactional.

    Development Status ๐Ÿ“–โ€‹

    A development prototype was created during the encode hackaton, the purpose was mainly to establish viability of Polkawatch and gather community feedback. Multiple strategies where tested/implemented during the 3 week development time in seek of viability.

    The prototype is a "hack" of a SubQuery project where a Lucene (elastic) index server is introduced. Several data structures are introduced to trace weak event releationships and map with external databases (GeoIP). A minimal dApp to present the data was also introduced and is available at https://polkawatch.app

    The current prototype has been useful is gathering feedback from participants about the potential of this project.

    Future Plansโ€‹

    Polkawatch will be used to raise awareness of decentralization of the network in the community.

    We plan to work with validators to improve their network share in the cases in which they improve the decentralization of the network.

    Ideally the data provided by Polkawatch could result in a Validator alliance with a decentralization brand promise such as avoiding crowded geographies or IP networks/cloud providers.

    We would also like to see decentralization turned into active economic policy. The same way that unavailability is slashed, validating in underrepresented geographies or IP networks could be rewarded. In that sense, we would like Polkawatch to become a tool to assist in policy decision making.

    Primis Desktop also is a place for users to subscribe to Polkadot decentralized notifications like EPNS. Initially, Primis Desktop will provide asset change notifications for Polkadot, Kusama, and other parachains. More on-chain DApps notifications to exploit in the future.

    Primis Web3 PNS Browser

    Primis Desktop will gestate a Chrome-compatible PNS browser for the Polkadot ecosystem, allowing Polkadot ecosystem users to access Web2 pages and interact with Web3 DApps freely. Primis Web3 PNS Browser supports Polkadot ecosystem PNS domainsโ€™ resolution and visit.

    Unlike traditional browsers such as Chrome, Brave, and Web2 centralized Cloud Service, Primis Web3 PNS Browser is based on a data relay network, where access and application data are transmitted to clients or Primis terminals through a relay network of Primis nodes.

    DApp Self-Hosting Platform

    Primis Desktop provides the plug-in function. All DApps on the Polkadot ecosystem can integrate and deploy on the Primis relay node network and upgrade and confirm through the reliable connection contract in a smart contract to ensure applicationsโ€™ security.

    Due to being the first Web3 desktop, Primis will interact with Polkadot's Web3 Ecosystem and bring the brand-new desktop concept to web3 users of Polkadot.

    All of our teammates truly believed in the Web3 Revolution! That's why we want to boot this Web3 project.

    Tech Stackโ€‹

    Supported Chains: Polkadot, Kusama, and other Parachains such as Acala, Astar, and Moonbeam.

    Client language: Electron, React

    Server language: Nodejs

    P2P language: Golang

    Ecosystem Fitโ€‹

    Primis is the first blockchain project known as the web3 desktop. And we want to attract more other ecosystems' web3 users to Polkadot ECO. Since primis is based on the concept of Web3, it has strong relationships with the most famous web3 organization W3F, and must be born here.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    PrivaDEX is a cross-chain DEX aggregator that enables cross-chain trading and unifies Polkadot's fragmented DeFi ecosystem.

    DeFi in Polkadot is frustratingly fragmentedโ€‹

    There are currently five parachains that each hold 10-35% of Polkadot's total DEX TVL, with four more parachains that plan to soon launch (or have recently launched) their flagship DEX. Despite having so many trading venues available, 80% of DEX users trade on a single parachain - and are thus limited to 10-35% of the available trading opportunities [1]. Pie chart

    The reason is simple; cross-chain trading is far too cumbersome. Executing a cross-chain swap is a 5 minute endeavor that requires several DEX swaps, manually bridging tokens, and waiting for all the transactions to be processed [2]. In short, DeFi in Polkadot is frustratingly fragmented.

    [1] Based on results from surveys like this one, collected from users of StellaSwap, BeamSwap, ArthSwap, and AcalaSwap.

    [2] Coming from a trading background, Kapil developed and ran systematic trading strategies in the Polkadot ecosystem a few months ago. At the time, liquidity was particularly scarce in light of the Nomad bridge hack and the Acala hack, necessitating multi-venue trading. Nevertheless, he found it impossible to systematically trade cross-chain due to the lack of existing automation.

    PrivaDEX defragments DeFiโ€‹

    PrivaDEX automates cross-chain messaging and smart order routing so that traders donโ€™t spend those 5 minutes manually executing one cross-chain trade. Now it's one step.

    By pooling liquidity from several DEXes across chains, PrivaDEX has access to more liquidity than any existing DEX. Further, it optimizes order splitting/routing to minimize price impact and achieve the best prices for users. PrivaDEX makes it 1-click-easy to efficiently trade across parachains.

    Project Detailsโ€‹

    Architectureโ€‹

    Technical flow

    Moving left to right in the above diagram, the development stack consists of

    1. Typescript and GraphQL for the blockchain indexing to generate price feeds
    2. Phat Contract Rust code, which looks like ink! smart contract code and acts like an AWS Lambda (off-chain stateless/serverless computing)
    3. React for the swap UI

    Proof-of-Conceptโ€‹

    We have developed a proof-of-concept for the executor module here. This PoC, implemented in a Phat Contract demonstrates the following steps:

    1. The user sends the sourceToken to the protocol.
    2. The protocol XCM asset transfers this token amount to the destinationChain.
    3. The protocol swaps sourceToken for destinationToken on the remote chain's Uniswap-like DEX.
    4. The protocol transfers destinationToken from its escrow account to the user's wallet on destinationChain.

    Existing Code and Design Documentsโ€‹

    Please check out the main repo. It contains some of the source code we have already written as well as design documents (in README files) for the incomplete items.

    Ecosystem Fitโ€‹

    Serving DEX users on every parachainโ€‹

    While Polkadot is designed for interoperability amongst chains, most XCM development efforts (e.g. X-Tokens/XTransfer pallets, bridges, remote execution) largely still serve developers, not lay end users.

    PrivaDEX is intended for DEX users on every Polkadot parachain. It enables users to conveniently trade cross-chain and efficiently trade intra-chain.

    Comparing to EVM DEX aggregatorsโ€‹

    There are no similar DEX aggregators in the Polkadot ecosystem. Other blockchains have DEX aggregators that generally fall under two categories:

    1. Intra-chain DEX aggregator like 1Inch: these find optimal routes by consolidating data from multiple DEXes on a single chain. There is no cross-chain component.
    2. Multi-chain DEX aggregator like Rango Exchange: these have poor (1) support for non-EVM chains, (2) UX, and (3) quality of routing solutions. PrivaDEX addresses these three shortcomings:

    (1) PrivaDEX has built-in Substrate and EVM compatibility and thus can uniquely integrate with any parachain (and associated XCMP channels).

    (2) PrivaDEX requires the user to sign just one transaction. Multi-chain aggregators like Rango require the user to sign a transaction each step of the way. This makes for a huge UX difference: users should be able to click a button and walk away, not need to stay on a webpage for minutes and sign multiple transactions along the way.

    (3) PrivaDEX smart order router logic involves splitting the route to optimize for price impact (which becomes a significant consideration where liquidity is relatively low). Rango never splits routes to optimize for price impact. Note that this is not a simple add-on feature because it is also a result of their requirement that a user sign every transaction - they would have to ask the user to sign 2-3x as many transactions to account for these split routes!

    Market Research & Inspirationโ€‹

    Kapil personally felt the need for a user-friendly aggregator when he was systematically trading on Moonbeam's DEXes from August to September 2022. Scaling any strategy on a single venue was impossible. Low liquidity meant high price impact, and diminishing marginal returns meant high opportunity cost. Manually swapping tokens and bridging them from various UIs took too much time and manual involvement.

    Parity's Rae Deng summarized the need for a DeFi aggregator in Polkadot in this Polkadot forum post:

    [There is a need for a] DeFi aggregator like 1inch or Matcha using XCM. Right now the liquidity is scattered on different parachains. It would be helpful to have a DeFi aggregator which can find the best route to swap assets by leveraging liquidity on different parachains.

    Current Progressโ€‹

    We have developed a proof-of-concept here.

    The work-in-progress source code and design docs (in README files) are in the main repo. We have made good progress on the price feed, chain metadata store, and network graph generation. Together, these components allow us to auto-generate a network graph of the ecosystem with real-time prices.

    You can find a snapshot of this token graph (comprising Polkadot, Moonbeam, and Astar; scraping data from StellaSwap, BeamSwap, and ArthSwap) that we auto-generated here (raw data is here).

    Development Roadmap ๐Ÿ”ฉโ€‹

    We had started development in the first week of October, so we have made good headway towards achieving the below milestones.

    Overviewโ€‹

    6.Graph libraryWe will heavily leverage the existing Rust graphlib library but make modifications to support no_std.
    7.Network graph constructionThis will combine GraphQL queries and the chain metadata store to create the graph using the above graph library.

    Milestone 2 โ€” Execution plan generator APIโ€‹

    An execution plan is a series of steps (e.g. swap ASTR for DOT on Arthswap, transfer DOT to Polkadot relay, etc.) to convert sourceToken on sourceChain to destinationToken on destinationChain.

    2.GraphSolution to ExecutionPlan converterThis Rust crate will translate a GraphSolution into an ExecutionPlan e.g. convert directed graph edges [ARSW -> ASTR, ASTR -> DOT, DOT_Astar -> DOT_Polkadot] into abstract instructions that can be used to submit transactions and extrinsics later.
    3.ExecutionPlan validatorThis Rust module will check invariants in the outputted ExecutionPlan to ensure it is valid and executable.

    Milestone 3 โ€” Executor Moduleโ€‹

    The executor module is Phat Contract code that actualizes the above execution plan, submitting transactions and extrinsics to perform swaps, bridges, and transfers.

    FAQs on Phat Contractโ€‹

    What is Phat Contract?

    • Phat Contract is a decentralized off-chain computation framework developed by Phala Network. Note that there is zero connection between Phat Contract and the Phala blockchain, as this framework is entirely off-chain.

    Why use Phat Contract?

    • Phat Contract allows us to securely store our protocol's keys (both wallet secret keys and off-chain storage API keys) in the contract (via the Trusted Execution Environment). As a result, we can submit transactions/extrinsics from a decentralized and transparent computing environment instead of a centralized service.

    How can we evaluate Phat Contract?

    • We will place all business logic in separate modules, and create a thin Phat Contract wrapper that ties the components together. That means that every logical component can be run from a standard computer because it will be normal Rust code (similar to Substrate blockchain code). In fact, one can even perform an end-to-end test (that moves and swaps real tokens) from a local environment since secret keys can be kept locally.
    • Estimated duration: 1.5 months
    • FTE: 2
    • Costs: 15,000 USD
    NumberDeliverableSpecification
    0a.LicenseGPLv3
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can call the Phat Contract execute the next step of their cross-chain swap.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to generate the WASM code. Note: Phat Contract runs in a Trusted Execution Environment and local deployment is not well supported yet. We will provide instructions on how to run this component via the Phat Contract UI.
    1.Rust Ethereum interface utilsThis Rust mod will provide helper utilities to construct Ethereum transactions and parse Ethereum transfers.
    2.Rust Substrate interface utilsThis Rust mod will provide helper utilities to wrap RPC calls (e.g. to query nonce, runtime version, block hash) and deserialize them into Rust-native structs.
    3.Substrate extrinsic signature and construction utilsThis Rust mod will handle the various chains' signature schemes (Sr25519 and ECDSA), and construct extrinsics using those signatures and payloads. This code will leverage components of subxt but note that we cannot use it as-is because of limited memory constraints in a Phat Contract. This means that we will need to write our own low-level code to encode extrinsics correctly.
    4.Phat Contract controller/driverAs the event driver that runs in the Phat Contract, this will have functions to process each supported ExecutionStep and create the appropriate transactions/extrinsics. It will also expose this processStep function to the caller.

    Milestone 4 โ€” Consolidated backend API and swap UIโ€‹

    The backend API ties together the above components and builds in a scheduler to handle multiple sequential steps, exposing REST functions that can be called from a browser. The swap UI provides a frontend for this API.

    • Estimated duration: 1.5 months
    • FTE: 2
    • Costs: 15,000 USD
    NumberDeliverableSpecification
    0a.LicenseGPLv3
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can use the API to execute their cross-chain swap.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerN/A. The main deliverables are the UI and its REST backend (that connects to the Phat Contract, which cannot be run locally), so containerization provides little value.
    0e.ArticleWe will publish an article/workshop that explains how to DEX users on how they can use PrivaDEX to perform cross-chain swaps and intra-chain aggregated swaps.
    1.S3 API for executorBuilding on Phat Contract's S3 example code here, this S3 API will perform state management for the executor e.g. keeping track of the status of an ExecutionPlan.
    2.Executor module schedulerLeveraging Phat Contract's rollup scheduler and the above S3 API, this scheduler will manage state and call the appropriate processStep function (from the previous milestone) for pending swaps. Note that Phat Contract inherently is stateless and because it requires wait times between block inclusion, it performs one step at a time.
    3.QuoteGetter APIThis API will be called by the UI to estimate a quote before the user requests a swap. It will construct the network graph and call the smart order router (as defined in the previous milestones), and estimate a quote based on the computed route.
    4.SwapRequest APIThis API will be called by the user via UI to transfer funds to the protocol and initiate the swap ExecutionPlan.
    5.GetSupportedChainTokens APIThis API will be called by the UI to generate a list of tokens (and chains) from/to which the user can swap.
    6.Swap UIThis Uniswap-like UI will use the APIs defined in this milestone for its backend calls. It does not require a database but will be hosted by a cloud provider. The frontend will leverage existing code e.g. components from the Uniswap interface.

    Future Plansโ€‹

    We will manage a Discord channel to communicate directly with end users. Closer to the end of the MVP development, we will make announcements to prepare for our launch.

    Long-term, we intend PrivaDEX to be a cross-chain DeFi hub for Polkadot. We will continue to improve the product and develop new features (e.g. parallel processing of execution steps to decrease slippage) to improve trade execution.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Profond.ai is web3 tools to help developers and creators to build, validate, and scale their dApps. We provide smart contract builder (NFT and token), analytic, and indexer.

    Weโ€™re focusing on emerging chain and we aim to onboard millions of developers by making it easier onboarding for users to create smart contracts.

    Project Detailsโ€‹

    Weโ€™re inspired by Pagoda.co, no code builders in the Near Ecosystem. It provides:

    1. No Code Builder: Create smart contracts for Token and NFT
    2. Indexer (coming soon): To help successful projects and enterprises scale their dApp.
    3. Analytics (coming soon): Data analytics for smart contracts, covering volume, users, transactions, and gas fees.
    4. API Analytics (coming soon): To get data from analytics.

    Currently, weโ€™re building MVP for users to create NFT and Token. Analytics, API and Indexer is still under development.

    Weโ€™re planning to add more parachains from Polkadot and Kusama to our platform. Hereโ€™s our current MVP: http://console.profond.ai/

    Create NFT CollectionNFT ToolsNFT Tools, currently require users to manually upload the collection via NFT-Up, weโ€™re working to make it drag&drop

    AnalyticsExample of smart contract analytic. In this image, weโ€™re doing analytic on marketplace.paras.near.

    Ecosystem Fitโ€‹

    We aim to launch on Polkadot and Kusama, hereโ€™s what problem weโ€™re trying to solve:

    • For creators, creating a smart contract for their NFTs and tokens is hard. Especially in relatively new WASM smart contracts like ink! .
    • For UI developers, blockchain development is too complex. Furthermore, each chain has its own complexity.
    • Limited tooling for Polkadot and Kusama ecosystem.
    • For emerging chain, we help them create smart contract templates.

    RainbowDAO Protocol ink! Phase 1

    • Team Name: Rainbowcity Foundation
    • Payment Address: 0xC2dA4D5813978BbC43d81e905dE6C98767526EdF (DAI)
    • [Level] 2

    Project Overview ๐Ÿ“„โ€‹

    RainbowDAO Protocol ink! is a series of smart contracts based on DAO infrastructure authorized and developed by the Rainbowcity Foundation. On the foundation of substrate development ecology, it focuses on the creation of web3 basic kits. These smart contracts are all created by the Ink! Framework. Anyone can create and manage their own DAO through RainbowDAO protocol. RainbowDAO protocol can build not only independent DAOs, but also parent DAOs, child DAOs and alliance DAOs. What's more, it can create management departments within DAOs to achieve multi-level management.

    Rainbow DAO Protocol ink! has built a complete web3 basic kit technology stack revolving around the DAO ecosystem, involving 12 items and 60 independent web3 kit systems. These 12 items are DAO Organizational Management System, DAO Token Management System, DAO Personnel Management System, DAO Treasury Management System, DAO Voting and Proposal Management System, DAO Contribution Management System, DAO Financial Management System, DAO Fundraising Management System , DAO marketing management system, DAO NFT ecological management system, DAO internal DeFi management system and DAO ecological tool management system. The 12 ecosystems contain 60 independent management modules, each of them can be combined and interact with each other for different function.

    Each module is developed based on the Ink! Framework, and we hope to realize the vision of a complete DAO organization Lego. It will take about 2 years to develop all the modules in DAO technology stack. We will divide the entire development plan into different phases. This grant application is the first phase of our development. We hope to realize the development of the basic module of the Rainbow DAO protocol and the creation of the DAO framework.

    Overviewโ€‹

    DAO is more than a set of smart contracts. In essence, it is a social organization, a physical network composed of individuals with a common purpose. The code of the same smart contract, used by different groups, may demonstrate huge differences in work. Members of DAO can either abide by the established rules or change them through collective decision-making. That sparks differences among DAOs. Obviously, members in DAO is the dominator in DAO classification.

    We did some research and collected the information about DAO in the encrypted world and initially divide DAO into eight major types:Protocol DAOใ€Investment DAOใ€Media DAOใ€Develop DAOใ€NFT DAOใ€Company DAOใ€Government DAO and Tool DAO.

    image

    As the crypto world continues to prosper and innovate, various forms of DAO organizations that are guided by distributed ideas have emerged. These DAO organizations are exploring first-line governance methods in their own ways, and continue to carry out various forms of organizational innovation and system innovation. In order to better serve these different types of DAO organizations, DAO tools that focus on developing DAO infrastructure have emerged. It is hoped that through this DAO tools, the operation and governance of the DAO organizations can be better realized.

    This DAO tool products have an extensive application, including but not limited to the construction of DAO framework, management of voting, proposal, bounty and multi-signature wallet management. Nowadays most of them zoom in Ethereum, such as aragon and DAOstack for DAO framework, gnosis-safe for Ethereum multi-signature wallet management, Snapshot for off-chain voting, etc.

    Except for Ethereum, we are glad that tool DAO platforms showed up in DAOs of Polkadot, such as subDAO and dorafactory. They are working for a better ecosystem of Polkadot.

    In the past year, with the explosive growth of various DeFi protocols and NFT protocols, various governance DAOs have achieved considerable development, accompanied by explosive growth in the demand for DAO tools. But after half a year of research, we found that although there are already many tool-based DAO projects in the encryption world, most tool-based DAO projects are still in the initial stage of industry development and there are many problems. At the same time, the entire industry of DAO also has various difficulties.

    After half a year of research, we have especially summarized some of the problems existing in DAO tool products and the current dilemmas in the DAO industry. In response to these problems and dilemmas, we have specially proposed our solution, which is the current RainbowDAO protocol.

    • Problems in DAO tool productsโ€‹

      In the last half a year, however, our team tried nearly all DAO tool products on the market. We discovered, DAO tool products are faced with the following problems:

      image

      • 1. Single product functionโ€‹

        The function of most of the DAO tool products is too simple,incapable of managing sophisticated coordination. Take the product for DAO framework, for example, what it provide is merely the building of DAO, DAO voting and fund management. Besides, we see no function for department management in any DAO framework, let alone Parent DAO , Child DAO and Alliance DAO. The current DAO tools products are far from satisfying the needs of sophisticated coordination.

      • 2. Low expansibilityโ€‹

        Most of the current DAO tool products have poor expansibility and cannot achieve functional upgrading. DAO will develop while the tool it initially used won't, which forces the DAO give up previous experience and select a new tool. That's a common problem in DAO industry.

      • 3.Low compatibilityโ€‹

        Most of the DAO tool products are not compatible, rendering collaborative governance impossible. The reasons are, on the one hand, different DAO tools are developed by different teams with divergent concepts, it is difficult for multiple products to cooperate with each other; on the other hand, the development standards of various DAO tools are different. Without a unified api or development document, DAOs can only use one or more products in isolation according to their actual needs.

      • 4.Low diversityโ€‹

        DAO tool products, most of them, can only meet the common requirements of DAOs, but cannot satisfy the diversified and differentiated needs yet diversification and differentiation are the characteristics of these different types of DAOs.

      • 5.Low operabilityโ€‹

        We found that most of the current DAO tool products generally have the characteristics of low operability, and users generally have poor experience in using them. Especially for some novice users, it is even more difficult to use these DAO tools.Low operability gave rise to poor experience for users. The design logic and details of these products is the key. That means development teams need take into consideration user experience.

      • 6.Poor innovationโ€‹

        We found that most of the current DAO tool products generally have the characteristics of poor innovation. The functional models of these products are all the same. They did not essentially solve some of the common pain points in the DAO industry. Most of them are similar. They haven't essentially conquered the difficulties in DAO industry. In the end, the products developed were not usable and reduced to a tool for capital speculation.

    • The difficulties in DAO industry.โ€‹

      After half a year of research, we found that although DAO represents the future, the current DAO field is still at a very early stage, and there are still a lot of problems and difficulties. We have now summarized some of the difficulties that currently exist in the DAO industry, mainly as follows:

      image

      • 1. How to establish a reasonable organizational structure while insisting on decentralizationโ€‹

        Any healthy and promising organization requires a clear structure and reasonable division of labour, which is often sophisticated and multi-layered. The current DAO tools can only carry out some primary collaborations, and cannot handle more complex or deep-level collaborations.We always believe that a true DAO organization needs to adhere to the thought of decentralization, but also needs a clear organizational structure.

      • 2. How to encourage participation of community membersโ€‹

        A large number of token holders do not care about the community's proposals and voting results. What they are interested is the price of the token. Therefore, the participation rate of many proposals is very low, and the performance of overall community governance is poor.

      • 3.How to guarantee a fair votingโ€‹

        A decentralized community is composed of multiple stakeholders, including whales, ordinary holders, investors and speculators. Their interest is different. In voting, in some cases, one token is one vote. And for other cases, one person is one vote. Both of the two models cannot safely protect voting fairness.RainbowDAO protocol offers different options in voting rights to refine the governance of the entire DAO system.

      • 4.How to quantify the contribution of community membersโ€‹

        At present, there are few good DAO tools to quantify the contribution of the members of the DAO. We believe this kind of tool is essential to DAO governance. We can establish generalized or differentiated bounty systems or reputation systems, credit systems, medal systems, honor systems, etc., to motivate community members to make more contribution.

      • 5.How to improve efficiency and strengthen power of execution while insisting on decentralizationโ€‹

        DAO community is decentralized and simultaneously loose in governance. Everyone is the own of the community but everyone can refuse to work. Thatโ€™s way many people donโ€™t believe in community. We need effective management, pragmatic collaboration system and tools and proper division of labor. We need a set of web3 tools to build a division of labor system, a work reporting system to improve the work mechanism referring to the existing experience in the company system. We always believe that the essential difference between DAO and company lies mainly in the decentralization of decision-making, rather than the decentralization of jobs or functions.

      • 6.How to successively conduct collective decision-makingโ€‹

        We always believe that the decentralization of decision-making is achieved by collective voting. But many of the members cannot decide whether they should support the proposal. One of the most important reasons is that they have no access to valid data. This requires various types of voting aids tools.

      • 7.How to establish a reasonable financial systemโ€‹

        DAO requires the participation of all members, which cannot be achieved without fund support. DAO needs a system for community fund allocation to deal with problems like the number of departments and its working groups, the budgets of these departments, their tasks, the application for expenses and so on. Financial management policy is a crucial part in RainbowDAO protocol.

      • 8.How to generate income for DAO and get income for its membersโ€‹

        DAO needs income to maintain high vitality and at the same time mobilize all its members to create income.In this regard, RainbowDAO protocol made some innovation. Members in some DAOs need to pay for membership. Then the service fee become the income of the DAO. Members can get a share of the fee if he managed to attract more people to join the DAO.

      To truly conquer these difficulties, we believe the most important thing is to provide these DAOs with universal and diversified DAO tools to make DAO governance systematic. That is also the mission for us to create RainbowDAO protocol today.

    • RainbowDAO Protocol ink! solution.โ€‹

      In the past two years, members of the Rainbowcity Foundation team have been conducting in-depth research on the DAO field. We hope to carry out in-depth innovation on the basis of existing products in the industry and develop tool products that truly meet the needs of the DAO market. At the same time, because the Ethereum community has the most mature DAO community, we have always focused on the Ethereum ecosystem for development, using Solidity as the development language for smart contracts.

      However, after research in the last six months, we found that the cost of using the Ethereum chain is constantly increasing, and the scalability of the underlying design of the Ethereum chain itself is not suitable for the large-scale development of DAO tools, so we will Focus on Polkadot ecology.

      After careful evaluation, we decided to fully embrace the Polkadot ecology initiated by Mr. Gavin Wood, adopt the substrate blockchain framework, and use the ink! framework to develop a series of products based on the DAO infrastructure facilities. We specially launched the RainbowDAO Protocol ink!, dedicated to solving the pain points and difficult problems in the industry, and boosting the DAO ecology towards real prosperity.

      And at the same time, apply for grant funding from the web3 foundation in phases to obtain development funds and achieve strategic cooperation and collaboration with the web3 foundation.

      In RainbowDAO protocol , we put forward the concept of DCV, which is the focus of the development of all DAO tools.

      image

      DCV, DAO Controlled Value, means that the value is not controlled by any single individual or centralized entity, but by DAOs at different levels. Through the DAO governance contract, DAO can control every core parameter and decision switch in the protocol, and ultimately the holder of the governance token can decide the direction of the entire DAO through voting.

      At the same time, in RainbowDAO protocol, there are different types of DAOs, including parent DAOs, child DAOs, alliance DAOs and departmental DAOs, so that more different types of participants can join in the construction of the DAO community to give full play to the power of communities.

    Project Detailsโ€‹

    In view of the current problems and difficulties in the Dao industry, in order to better meet the needs of the Dao industry and develop Web3 suite tools in line with the actual operation of Dao, Rainbowcity Foundation specially developed a series of protocols: RainbowDao Protocol ink!.

    The following are the details of the : RainbowDao protocol:

    image

    • Three major innovations of RainbowDAO protocolโ€‹

      • 1. Governance Dao functionโ€‹

        In RainbowDAO protocol, we innovatively developed the function of Governance DAO, which gave wings to the expansion of the entire protocol. The governance DAO function is mainly reflected in two points:

        The first point is that the entire RainbowDAO protocol is controlled by a governance DAO. We will issue governance token RBD. The holder group of RBD is the governance group of the RainbowDAO protocol. The group of RBD holders decides the modification of the parameters of the entire RainbowDAO protocol through referendum voting, and continuously upgrades the protocol itself.

        The second point is that each independent DAO created through the RainbowDAO protocol will generate a governance DAO and bind the corresponding governance token. The governance DAO manages the independent DAO and is responsible for the modification of the DAO parameters. Through this governance DAO finally realize the upgrade and expansion of this independent DAO.

        The combination of these two points makes the entire protocol no longer a fixed protocol, but an protocolt that is constantly upgraded through governance. In this way, the entire protocol can truly have vitality and growth.

      • 2. RainbowCore functionโ€‹

        We innovatively developed the RainbowCore function and used it as the authority control center of the RainbowDAO protocol. The RainbowCore module is divided into four parts, Role management, Authority management , Route management, and Rainbowcore.

        The Role management contract is responsible for managing different roles in the protocol, the Authority management contract is responsible for managing the permissions corresponding to these roles, and the Route management contract is responsible for the address management of all contracts in the entire protocol. The Rainbowcore contract is the entry management of these three contracts, overall planning and coordination.

        The four major functions of the RainbowCore module build the RainbowDAO protocol into a whole that can be flexibly matched with different roles and different permissions, and finally can achieve unlimited expansion and upgrade of the protocol.

      • 3. DCV controller functionโ€‹

        We have also innovatively developed the function of the DCV controller, which enables the entire RainbowDAO protocol to have unlimited scalability. DCV is the core function of RainbowDAO protocol. Each DAO is based on the management of DCV, and each DCV is an independent treasury system.

        We have innovatively developed the DCV controller function. Each controller is a series of existing rules written by smart contracts to complete the specified contract operations. In this way, the management of DAO has unlimited scalability. Through the DCV controller function, each DAO itself can flexibly control the assets in the DCV.

    image

    • Eight features of RainbowDAO protocolโ€‹

      • 1. Modularityโ€‹

        Each function of RainbowDAO protocol can exist as an independent module, which can easily trigger upgrading and evolution of the protocol.

      • 2. Plug-inโ€‹

        Each module of the RainbowDAO protocol is very flexible like a plug-in.

      • 3.Composabilityโ€‹

        Each module of the RainbowDAO protocol can be combined with each other. Some simple modules can work together to form a powerful module.

      • 4.Scalabilityโ€‹

        Based on the modular combination, the RainbowDAO protocol has very strong scalability and new functions can be added through the addition of modules.

      • 5.Detachabilityโ€‹

        The modules of the RainbowDAO protocol can be disassembled to achieve the simplification of DAO functional modules and adapt to actual needs.

      • 6.Interoperabilityโ€‹

        Each module of the Rainbow DAO protocol is can interact with each other.

      • 7.Flexibilityโ€‹

        The RainbowDAO protocol can be combined, extended, and disassembled. This gives the RainbowDAO protocol strong scalability. The protocol can be adjusted according to the actual situation of each DAO.

      • 8.Growthโ€‹

        Based on the first 7 characteristics, the RainbowDAO protocol will evolve into a living system that can upgrade infinitely with a decentralized idea.

    image

    • Eight concepts of RainbowDAO protocolโ€‹

      After half a year of research, we found that although DAO represents the future, the

      • 1. Decentralizationโ€‹

        It is the soul of the RainbowDAO protocol. The protocol itself and DAOs of all levels are decentralized .

      • 2. Trust-freeโ€‹

        RainbowDAO protocol adheres to the idea of "code is law". All rules are constructed by code with no need for intermediary.

      • 3.Censorship-Resistantโ€‹

        All rules of the RainbowDAO protocol are set by code to achieve complete on-chain governance, and the value of all assets is controlled by the chain.

      • 4.Transparencyโ€‹

        The RainbowDAO protocol realizes complete on-chain governance. All data is clearly displayed on the chain.All data is transparent.

      • 5.No need for permissionโ€‹

        The RainbowDAO protocol is composed of countless rules that have been set up in advance. They are constructed by smart contracts on the chain. Anyone can use the RainbowDAO protocol to build a DAO without permission.

      • 6.Opennessโ€‹

        RainbowDAO protocol is a set of open protocols and these protocols can interact with internal modules and external protocols.

      • 7.Popularityโ€‹

        RainbowDAO protocol can be applied to various types of DAOs, large or small in size.

      • 8.Inclusivenessโ€‹

        The RainbowDAO protocol can be employed by different types of people. We always hope to build the RainbowDAO protocol into a viable, growing, and warm protocol.

    image

    • Twelve items of RainbowDAO protocolโ€‹

      In order to better serve the entire DAO ecological infrastructure, we built a complete web3 basic suite technology stack around the entire DAO ecosystem, involving a total of 12 major items and 60 independent web3 suite systems.

      The 12 major items include 60 independent management systems, each of which is an independent module, and all modules form a complete DAO infrastructure service technology stack. Each module can be used independently, and different modules can combine with each other, which truly realizes the vision of DAO Organization Lego.

      This is our grand plan for the entire DAO infrastructure. The entire plan is too large, we will develop it in stages, and the overall development is expected to be completed in 2 years. This first grant applied for us to focus on the first item of the whole development.

      • 1. DAO Organizational Management Systemโ€‹

        Basic system of RainbowDAO protocol for the establishment and management of DAOs. It is the basis of all the other items of RainbowDAO.We can not only build the simplest DAO, but also a very large and complex DAO. Including but not limited to independent DAO, parent DAO and child DAO, as well as alliance DAO.

      • 2. DAO Token Management Systemโ€‹

        This part is mainly related to the various modules of token management. At present, various DAO infrastructures rarely have slightly complicated token management systems, which makes it impossible to realize the management and coordination of some complex tasks. In response to such pain points, in the RainbowDAO protocol, we design a variety of different forms of token management functions. Including but not limited to ERC20 Token Factory, Token Airdrop Management System, Token Locked Management System ,Token Exchange Management System, Multi-signature Wallet Management System.

      • 3.DAO User Management Systemโ€‹

        Itโ€™s about the the member management of the entire RainbowDAO protocol. This management pattern can be employed in all independent DAOs, they can choose one or more parts of the system and they can combine these parts for their own use. Currently, thereโ€™re merely some simple functions there. We will develop more sophisticated ones based on the reality of RainbowDAO protocol.

      • 4.DCV Management Systemโ€‹

        DCV, DAO Controlled Value, is one of the core management system of RainbowDAO protocol. In the early stage, we design only relatively simple management functions of DCV. With the improvement of the protocol, we will design diversified DCV controllers for better management.

      • 5.DAO Voting and Proposal Management Systemโ€‹

        Proposals can be divided into different types, and the corresponding processes will be different. For example, some proposals have two options, support or oppose, some proposals need to elect different candidates, and the voting result is determined by the number of votes. This requires us to consider the difference of proposal types and make different templates.

        Under the rules of different DAOs, some voting rights can be calculated by token, one token is one vote; some are calculated by voter, one person is one vote. These different programs can all be applied to different governance environments.

      • 6.DAO Contribution Management Systemโ€‹

        DAO's contribution management is mainly to guide community members to contribute to the governance of DAO through appropriate methods, and to give full play to the enthusiasm and initiative of community members. Most community members want to contribute to the community, but suffer from methods and approaches that have not contributed, and cannot get incentives through contributions.

      • 7.DAO Finance Management Systemโ€‹

        The system is about some financial tools that may be used in DAO management, in financial procedure and policy-making to make the overall capital flow more transparent and orderly.

      • 8.DAO Fundraising Management Systemโ€‹

        Use different tools to raise funds for DAO from different channels.Only DAO has sufficient funds to support its long-term stable development. Therefore, diversified fundraising tools are a necessity for DAO operations.

      • 9.DAO Marketing Management Systemโ€‹

        With DAO as the center, various marketing platforms or competition platforms are opened to encourage users to carry out promotion and ultimately lift the popularity of DAO.

      • 10.DAO NFT Management Systemโ€‹

        To create a set of tools for the production and circulation of various NFTs. We will take DAO as the center to build a prosperous NFT ecology on the basis of Polkadot.

      • 11.DAO DeFi Management Systemโ€‹

        We will develop various DCV controllers to control the funds in DCV, and participate in diversified DeFi activities, which can maximize the efficiency of the use of funds in DCV and increase the rate of return of funds.

      • 12.DAO Ecological Tools Management Systemโ€‹

        It's about various ecological tools in DAO. Instead of focusing on a specific field, it involves all aspects of the overall operation of DAO. The tools can be technical or service-oriented.

    • Function product display of RainbowDAO protocolโ€‹

      In this chapter, we will show the product functions of the RainbowDAO protocol, especially the structure and logical relationship. We hope to let people understand the framework of RainbowDAO function through this frame diagram.

      The RainbowDAO protocol is part of the DAO Basic Framework protocol. Anyone can create an independent DAO through the RainbowDAO protocol. A three-part extension can be carried out through an independent DAO, and finally it can be upgraded infinitely.

      • 1. Scale up: Alliance DAOโ€‹

        An independent DAO can join a Alliance DAO. In this product structure diagram, we first virtualized several alliances. For example, we have established a project on the Polkadot main chain. Based on this project, we have established a DAO. This is an independent DAO. Our independent DAO can join the Polkadot Ecological Alliance DAO , which is an Alliance DAO. Similarly, projects on the kusama main chain can also join the Alliance DAO on the kusama main chain, and each parachain can set up an independent Alliance DAO to attract projects on the parachain to join the parachain Alliance DAO.

        Similarly, whether it is the Polkadot chain, the kusama chain, and each parachain, they are all built using the substrate framework. We can establish a substrate ecological Alliance DAO. The Polkadot Ecological Alliance DAO, the Kusama Ecological Alliance DAO, and the Alliance DAOS of various parachains can all join this substrate Ecological Alliance DAO, Ultimately realize the sharing of resources.

        This example is the Alliance DAO established from the perspective of development technology. According to the differences in DAO attributes and types, we can also establish investment Alliance DAO, media Alliance DAO, social Alliance DAO, and so on. Similarly, we can also establish Alliance DAOs in different regions through regional differences. The European Alliance DAO, the Asian Alliance DAO, the American Alliance DAO, and so on.

        In Alliance DAO management, an independent DAO can freely choose to join an Alliance DAO or leave an Alliance DAO without the permission of the Alliance DAO. There are no rigid management and ownership requirements between each other.

      • 2. Scale Out: Parent DAO and Child DAOโ€‹
    Each independent DAO can establish its own Child DAO. In fact, this is equivalent to the relationship between the parent company and the subsidiary. Each Child DAO belongs to an independent DAO in terms of attribution, and is exactly the same as an independent DAO in terms of functional modules. The Parent DAO has the right to manage the Child DAO.Unless the  Parent DAO agrees to the independence of the Child DAO through a referendum, the Child DAO cannot exist independently.

    Child DAO is created by the Parent DAO, the Parent DAO has the authority to control the Child DAO, the Child DAO of the Child DAO can also be managed by the Parent DAO, and so on. Child DAO has management authority to directly belong to Child DAO, and cannot be cross-level management. Example: Parent DAO A creates Child DAO B, Child DAO B creates Child DAO C, and Child DAO C creates Child DAO D. The Parent DAO A has the management authority of B, C, D, and Child DAO B has the management authority of Child DAO C. But Child DAO B does not have administrative rights to Child DAO D. The Parent DAO can perform cross-level management of Child DAOs, but cross-level management between Child DAOs is not possible.
    • 3.Scale In: DAO department managementโ€‹

      Each independent DAO can establish a department belonging to this independent DAO, which means that this independent DAO can establish its own clear organizational structure. This is also the core function of the RainbowDAO protocol that we have always emphasized. We have always believed that any DAO cannot have only one department, but should have multiple departments working together.

      In the RainbowDAO protocol, each department established by an independent DAO is also equivalent to an independent small DAO, with various basic functions of the DAO. But it is not an independent DAO in nature, but a sub-department within an independent DAO. In our overall product planning, the management authority of these sub-departments is more in the form of multisig smart contracts, and a multisig committee is responsible for managing this department, rather than through voting for all DAO members. This is the decentralization mechanism of DAO management, which decentralizes the overall power to the department for processing.

      In the same way, a department can continue to set up departments to further decentralize and distribute power. Establish collaborative work with complex tasks through the department's layers. This is the most basic function we think a large DAO must have.

      In the same way, a department can continue to set up departments to further decentralize and distribute power. Establish collaborative work with complex tasks through the department's layers. This is the most basic function we think a large DAO must have.

      We also give examples in the framework diagram to facilitate everyone to understand our product logic. First of all, we established an independent DAO. In the department management of this independent DAO, we established five independent departments. They are the Human Resources Management Committee DAO, the Financial Management Committee DAO, the Technology Management Committee DAO, the Operation Management Committee DAO, and the Investment Management Committee DAO. These five departments are responsible for the specific operations of this independent DAO.

      At the same time, these five independent departments are divided into different groups under each department, and continue to refine the division of labor. For example, the Human Resources Committee DAO is divided into two groups: the organizational structure management group and the salary management group; the Financial Management Committee DAO is divided into the budget management group and the fund use management group; the Technology Management Committee DAO is divided into the technology development management group and Grant supports these two groups; the operation management committee is divided into the brand management group and the event promotion management group under the DAO; the investment management committee is divided into the project review management group and the foreign investment management group and so on.

      Most of these management groups also exist in the form of a multisig management committee. This is also a function of DAO's decentralization to the following independent departments. Complex coordination must be achieved through refined division of labor, which is the same nature as the operation of a company. Only with clear division of labor and clear responsibilities can it be possible to improve efficiency and execution.

    • Design mechanism of RainbowDao protocolโ€‹

      Through the above series of information, we have learned about the grand plan of RainbowDAO protocol, which is a huge project that allows DAO to expand infinitely and upgrade infinitely. So how is the RainbowDAO protocol constructed as a whole? What is the structure of the protocol itself? In this part, we focus on sharing with you the architecture design of the RainbowDAO protocol itself, so that everyone can clearly know the implementation method of the RainbowDAO protocol.

      We can understand the design architecture of the RainbowDAO protocol from three parts.

      • 1.Tier 1 Architecture: RBD Governance Daoโ€‹

        The first layer of the RainbowDAO protocol consists of RBD governance DAO. RBD belongs to the governance token of the RainbowDAO protocol. The holders of RBD constitute the DAO and are responsible for the governance and management of the entire RainbowDAO protocol. RBD governance DAO coordinates all the parameters and conditions of the RainbowDAO protocol. The holders of RBD voted to determine the modification and optimization of each parameter of the RainbowDAO protocol, and realize the expansion and upgrade of the RainbowDAO protocol. The RBD governance DAO belongs to the overall control center of the RainbowDAO protocol, and all management powers belong to the owners of all RBD governance tokens.

      • 2.Tier 2 Architecture: Basic Protocol Layerโ€‹

        The second layer of the RainbowDAO protocol is the basic part of the protocol, not the part of the DAO created by the protocol. Basic Protocol Layer mainly contains six parts, one is the rainbow core contract, the second is the membership management contract, the third is the revenue management contract, the fourth is the web3 suite tool contract, the fifth is the DCV controller contract, and the sixth is the DAO factory contract. The DAO factory contract also belongs to the third layer of the RainbowDAO protocol, which is mainly used to control and manage the DAO created by the protocol.

        Rainbow core contract consists of four parts, role management contract ,authority management contract, routing management contract and rainbowcore management contract . This is the permission control center of the RainbowDAO protocol, which manages the permissions and roles of the entire protocol, and is responsible for the upgrade of the RainbowDAO protocol.

        The membership management contract is responsible for managing the members of the protocol as a whole. One is to manage the identity information of the members, and the other is to manage the recommendation relationship of the members. The recommendation system and membership management modules are developed from this.

        The revenue management contract belongs to the revenue management control center of the RainbowDAO protocol. RainbowDAO protocol itself will set a series of income categories, such as calling the contract requires payment of DOT as a contract usage fee, DCV will charge a certain percentage of the treasury usage fee and so on. In this way, the RainbowDAO protocol can generate revenue in a variety of ways. The more people who use the protocol, the more income they can get. The final income will also be proportionally returned to the holders of RBD governance.

        Tool contracts related to Web3 belong to the management center of tool contracts. For example, ERC20 token manufacturing factory contract, multisig wallet management contract, token airdrop contract, token lock-up contract and so on. In the future, all tool contracts can be placed under this large module.

        The DCV controller contract belongs to the controller management center of the Rainbow DAO protocol. Various controllers can be made here, especially when it comes to DeFi management.

      • 3.Tier 3 Architecture:DAO Factoryโ€‹

        The above contract parts belong to the overall level of the RainbowDAO protocol. The third layer belongs to the DAO Factory contract, which is mainly used for the batch creation and management of DAO.

        The DAO Factory contract can be divided into three parts .

        The first part belongs to the DAO type contract. The DAO type is divided into three types: independent DAO, Alliance DAO, and Child DAO, which directly determines the most basic nature of the established DAO.

        The second part belongs to the DAO initialization contract, which is used for DAO creation and initialization information.

        The third part belongs to the DAO management contract, which belongs to the basic management of the contract after the establishment of the DAO.

        The DAO management contract is mainly divided into 7 modules.

        The first module is the DAO basic setting contract, which is mainly responsible for the setting of DAO basic information;

        The second module is the DAO authority management contract, which is mainly responsible for the authority, role management in this DAO and the termination and liquidation of DAO;

        The third module is mainly the DAO member management contract, which is responsible for the member management of this DAO, including the entry threshold and the deletion of members, etc.;

        The fourth module is the DAO treasury management contract, which is mainly responsible for DAO's treasury management ;

        The fifth module is the DAO voting management contract, which is mainly responsible for a series of voting rights related settings;

        The sixth module is the DAO proposal management contract, which is mainly responsible for DAO proposal management;

        The seventh module is the DAO department management contract, which is mainly responsible for department management of DAO.

      These three parts constitute the basic framework of the RainbowDAO protocol. In the future, the RainbowDAO protocol will be continuously upgraded and expanded on the basis of these basic frameworks, and will become the infrastructure of the DAO industry.

    Ecosystem Fitโ€‹

    Help us locate your project in the Polkadot/Substrate/Kusama landscape and what problems it tries to solve by answering each of these questions:

    image

    • Where and how does your project fit into the ecosystem?

      First of all, the Rainbowcity Foundation chose the Polkadot ecology of Dr. Gavin Wood. From a long-term perspective, we have a total of three levels of planning to integrate into the Polkadot ecosystem through three steps.

    • In the first step, we will develop a series of smart contracts that belong to the DAO infrastructure based on the ink! framework. This is RainbowDAO Protocol ink!. All protocols exist in the form of smart contracts, so that they can be widely deployed on any Parachains and independent public chains developed based on Polkadot, Substrate and Kusama networks.

    • In the second step, we will develop based on the parachains of Polkadot and Kusama, transform some of the smart contracts involving the underlying architecture into the form of a pallet, and we will create a parachain that belongs to the DAO infrastructure. Part of the DAO infrastructure exists in the form of pallets, and part of the DAO infrastructure exists in the form of ink! smart contracts. Pallet involves the creation of DAO facilities at the lower level of the parachain, while smart contracts tend to create DAO tool types with greater flexibility. In this way, we will build a parachain based on the DAO infrastructure and rely on this parachain to build an ecosystem. The project parties deployed on this parachain all use RainbowDAO Protocol ink! for project governance, building a fully community-driven, decentralized governance parachain.

    • The third step is that in the next 3 to 5 years, with the stable development of Rainbow DAO's smart contracts and parachains, we will start to build an independent public chain of Rainbowcity based on the substrate framework with an independent consensus mechanism. The ecosystem will be further built on the basis of the independent public chain of Rainbowcity. The focus of the ecosystem is on the token economy and community governance, with DAO governance as its soul. We will migrate a series of physical industries to the Rainbowcity independent public chain, which is a further extension and expansion of the substrate ecosystem.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

      • First, for ourselves, we will initiate our independent project RainbowDAO based on RainbowDAO Protocol ink! in good time, committed to the creation of DAO infrastructure, and truly serve the Polkadot DAO ecosystem.

      • Second, any project party who wants to create a project based on Substrate / Polkadot / Kusama. Because our protocol exists in the form of a smart contract, allowing anyone to use it. Therefore, any project party can refer to, modify or directly deploy our code to provide DAO infrastructure for the entire Polkadot ecosystem. We treat all participants with a completely open attitude.

      • Third, any parachain builder can directly adopt our code and deploy it on their parachain to provide DAO infrastructure for the project parties on their parachain.

      • Fourth, when RainbowDAO Protocol ink! is deployed on a large scale in the Polkadot ecosystem in different ways, any type of DAO can use our protocol to create their DAO, and help them operate and manage their own DAO to the greatest extent.

    • What need(s) does your project meet?

    Provide DAO infrastructure and web3 tool suite for various types of DAO.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    We found that there are already DAO infrastructure-based projects in the Polkadot ecosystem, such as subDAO and dorafactory. At the same time, there are also a large number of related projects in the Ethereum ecosystem, such as aragon and DAOstack focusing on the DAO framework, gnosis-safe focusing on the management of multi-signature wallets, and snapshot platform Snapshot focusing on off-chain voting. Compared with these existing projects, RainbowDAO Protocol ink! can handle more complex DAO governance and collaboration. Our protocol itself is more extensible, more flexible, more vital, creative and innovative. For specific details, please refer to the three innovations, eight features, and eight concepts of the RainbowDAO protocol described in the text above. These are our core competitiveness, and are also the basis for the continuous development and evolution of our products.

    Team's experienceโ€‹

    We have a full-time team of more than 20 people, including 11 full-time development teams, mainly Ethereum ecological development. Since 2019, under the leadership of RainbowKun, our team has prepared the Rainbowcity project entirely with our own funds. Rainbowcity is committed to building a digital city-state based on token economy and community governance. The core idea of Rainbowcity is DAO. We hope to build Rainbowcity into a trillion-dollar super-economy through 10 years of development, and create a virtual city-state based on the blockchain, and create a free state that adheres to the spirit of bitcoin, and to create a new civilization for mankind.

    Rainbowcity is a DAO, and the design of the entire project is centered on DAO. In 2020 and 2021, the main work of our team is to design the Rainbowcity project and develop Rainbowcity DAO. In the past, we focused on the Ethereum market and built the entire ecosystem of Rainbowcity on the Ethereum main chain and L2 network in the form of smart contracts. Therefore, our team mainly develops RainbowcityDAO smart contracts based on solidity.

    In the past year, we have developed a complete product of RainbowcityDAO in solidity language. The entire product has more than 100 smart contracts, including more than 60 core contracts, more than 20 coordinator contracts for contract deployment, and more than 30 interface contracts. The development workload is one of the largest projects in the Ethereum ecosystem.

    However, when we fully developed the RainbowcityDAO contract, after a comprehensive evaluation by our team, the Ethereum ecosystem could not support the operation of the entire Rainbowcity project. On the one hand, the cost of using the Ethereum main chain is getting higher and higher, on the other hand, the overall performance and future scalability of the Ethereum main chain cannot support the operation of the Rainbowcity project.

    At this time, we are faced with multiple choices in the future development direction. One is to continue to stick to the Ethereum ecosystem, wait for the maturity of the Ethereum L2 network, and build the Rainbowcity ecosystem on the basis of the L2 network. The second is to build a completely independent public chain by ourself, and build the Rainbowcity ecology in the form of our own public chain. The third is to choose other emerging public chains in the market.

    After various investigations, we chose the Polkadot ecosystem created by Dr. Gavin Wood to conduct a comprehensive investigation on the Substrate, Polkadot and Kusama ecosystems. We pay particular attention to the ideas and concepts of the Parity team and the web3 foundation team led by Dr. GavinWood to see if these concepts are decentralized. As we learn more about Dr. GavinWood, we find that Substrate and Polkadot are our best choices.

    Therefore, in June 2021, we made the biggest decision of our team in the past three years to suspend our development and research in the Ethereum ecosystem and join the Substrate and Polkadot ecosystem created by Dr. Gavin Wood. Our developers have also begun to switch development languages, starting from the original solidity to Rust and ink!. This is the most important decision our team has made in the past three years. Abandoning the familiar technology and learning new development technology is also a major challenge for our development team. However, we are not afraid of this challenge, and actively embrace this challenge. We firmly believe that Substrate and Polkadot belong to the future of blockchain.

    At the same time, inspired by the relationship between Substrate and Polkadot, we have also adjusted the product structure. The original Rainbowcity was an independent project, an independent DAO, and our development was also based on this DAO. All our development needs are the needs of the project itself, and these DAO tools cannot meet the general needs of other DAOs. Inspired by the relationship between Substrate and Polkadot, we decided to abstract the product that was originally only applicable to RainbowcityDAO and make it applicable to various DAOs. This is why we launched RainbowDAO Protocol ink! today. Our team has been conducting research internally for the past six months, and now we have a preliminary and complete system.

    In order to quickly integrate into the Substrate and Polkadot ecosystem, we decided to participate in the grant application of the web3 foundation to start our Polkadot journey. Through the grant application of the web3 foundation, participants in the entire Polkadot ecosystem can have a more systematic understanding of our development philosophy and future vision. We hope to use the grant platform as our first step to integrate into the Polkadot ecosystem, show our strength and our grand vision step by step, and become a part of the Polkadot ecosystem.

    At the same time, in the past two years, due to the need for project confidentiality, our development team has not released any project information. The github accounts of all our members are also newly registered, so there is not much history. In order to let the web3 foundation grant team have a simple understanding of our development capabilities, we uploaded the previously developed RainbowcityDAO project source code to github.

    It is our regret that these codes were abandoned without formal use. We will start the creation on Polkadot from scratch. Of course, we will not completely abandon the development on Ethereum. In the future, we will also develop the solidity version of the RainbowDAO protocol simultaneously.

    Development Status ๐Ÿ“–โ€‹

    Our leader RainbowKun is a believer in Satoshi Nakamoto and Bitcoin. He has been thinking about the philosophy of Bitcoin for the past four years. Since July 1, 2021, he spent 3 months writing more than 50 original articles on Bitcoin thoughts, and published them on the Bitcointalk forum created by Satoshi Nakamoto, sparking a series of extensive discussions. This is also the underlying idea that we initiated the creation of the Rainbowcity project and the RainbowDAO protocol. Now we choose a few links for everyone to read, so that everyone can better understand the thoughts of Rainbowcity:

    For the past two years, we have been developing RainbowcityDAO products on the Ethereum network. Here are some UIs we designed for your reference.

    Development Roadmap ๐Ÿ”ฉโ€‹

    The entire RainbowDAO Protocol ink! is a huge project, involving 12 large modules and 60 small modules. It is estimated that it will take one to two years to complete the development. We decompose some core modules into 3 to 5 different phases, develop step by step, and apply for grant support from the web3 foundation.

    In the first phase of our overall development, we mainly completed the basic framework part of the RainbowDAO protocol. The first part is the protocol layer of the RainbowDAO protocol itself, and the second part is the RainbowDAO factory contract, which is used for the construction of the DAO Factory. Both parts are basic functions, and the extended function part is not involved for the time being. When our first phase is completed and the RainbowDAO protocol can operate normally, we will develop various extension modules.

    Overviewโ€‹

    • Total Estimated Duration: 8 weeks
    • Full-Time Equivalent (FTE): 8
    • Total Costs: 48000 USD

    Milestone 1โ€‹

    • Estimated duration: 3 weeks
    • FTE: 8
    • Costs: 20,000 USD

    For the first milestone, we focused on developing some basic contracts of RainbowDAO Protocol ink!, that is, the underlying structure of the entire protocol. Including governance DAO contract, ERC20 factory contract, multisig management system contract, user management system contract, income category management contract, role management contract, authority management contract, routing management contract, rainbowcore management contract, etc., a total of 9 systems.The name, function or quantity of the final developed contract may be different from the estimate in this table. At that time, the actual developed code shall prevail.

    Milestone 2โ€‹

    • Estimated Duration: 5 weeks
    • FTE: 8
    • Costs: 28,000 USD

    For the second milestone, we focused on the development of DAO factory contract related functions, and the front-end page, and the interaction between the front-end and the contract. The name, function or quantity of the final developed contract may be different from the estimate in this table. At that time, the actual developed code shall prevail.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    We are sincerely requesting a funding grant from the web3 Foundation to build a transaction firewall that will function as a last resort security barrier when user asset protection solutions fail. There have been several serious security incidents recently, including major asset losses due to the theft of private keys on the harmony and Ronin bridges. In the blockchain world, having a mnemonic or private key for an account is equivalent to getting ownership of that address; when a hacker obtains a user's mnemonic or private key, he or she is able to take all the assets in a short period of time without any problem, a situation that obviously should not exist all the time. When this problem is not solved or alleviated, the Web3 world is full of uneasiness and suspicion, and this situation will make it difficult for the Web3 world to gain larger scale support and popularity.

    The Redstone Network is a network of trigger circuits where users combine and arrange simple atomic trigger components according to certain rules and processes to eventually implement a series of automated operational circuits. We propose transaction firewall middleware that can function between any blockchain network, regardless of the cross-chain mechanism and network topology used to execute asset transfers, and regardless of the type of assets traded, we will construct a firewall of different security levels for users. With the help of triggers and machine learning technologies, we will provide users with passive defense and proactive alerting capabilities.

    We will work with parallel chains in Polkadot/Kusama to build and deploy the firewall function to enable a higher level of security for parallel chain asset interactions within the ecosystem; in addition, we can work with project parties or wallets in other ecosystems to provide them with this unique defense mechanism, ultimately reducing the risk of asset security across the Web3 world.

    Project Detailsโ€‹

    For the transaction firewall functionality, Redstone Network will build a set of on-chain/off-chain trigger components and their implementations. In general, users will not be aware of the firewall's operation, and the firewall will truthfully notify users of potential security risks when there are triggered alarms on the chain.

    Passive defense and active alarmsโ€‹

    • We build a series of stateless atomic trigger components, including on-chain triggers (quantity trigger, time trigger, price trigger), off-chain triggers (mail trigger, discord trigger, slack trigger) and off-chain message interaction components, which are responsible for actively obtaining external information or pushing messages to a specified server.;

    • Analyze transaction characteristics and behavior, design transaction protocol analyze the transaction characteristics and behavior, design the transaction protocol, check whether the basic information and check information of the transaction match through protocol parsing, and initially determine the validity of the transaction;

    • according to the trigger and the transaction protocol, with the idea of social recovery and multiple signatures, formulate different security level trigger policies for users, including power grabbing mechanism, freezing mechanism and alarm mechanism.

    Intelligent termination of transactions with evil address monitoringโ€‹

    The user-configured security scheme can effectively defend against known security problems, but not against unknown or unconfigured behaviors. By analyzing the transaction data recorded in the database under the chain, the transactions are analyzed according to the dimensions of transaction time, transaction frequency, transaction address, transaction direction, and transaction amount, and if the transaction behavior is different from the daily behavior, the meltdown mechanism will be triggered and alarmed; receiving the supervision instruction from a chain, the address that is doing evil and the derived address will be dynamically analyzed and the transaction meltdown mechanism will be triggered.

    For the application scenario of transaction firewall, it is mainly divided into token assets and NFT assets. Users can choose the type of asset that needs to be configured with the firewall, either for a certain token, or to protect the account that issues NFT assets.

    In addition, the transaction firewall feature is not dependent on any application, any architecture and any address type restrictions, making it flexible to handle a variety of new attack methods that are known or have not yet emerged in the future, as it aims to study the security of A to B transfers.

    Technology stack

    • Rust: Develop on-chain trigger/defense/alert modules
    • Go/Python: Develop off-chain analysis/trace/alarm modules

    Ecosystem Fitโ€‹

    This project will be developed, deployed and run based on the Substrate framework. Unlike other trigger projects, with the advanced features of OCW, we are able to provide users with an advanced on-chain alert push mechanism, which will help shorten the time for users to get critical information. At the same time, rooted in Polkadot/Kasuma ecology, as a parallel chain, the trigger interface on it will provide additional application features for all parallel chains, and with the help of relay chains, it can facilitate unique transaction defense capabilities for other parachains. We note that we are entering a completely new area that will provide an unprecedented protection experience for the blockchain space once our project is in actual operation.

    1.Passive_Defense PalletWe will provide users with stateless and application-independent protective features, and this module will be implemented through Substrate Pallet:
    transaction limit configuration: configure in advance the limit of transferring a transaction amount and limit the frequency of transactions within a specified time; protect users from suffering significant losses for a short period of time when their private keys are stolen.
    Freezing configuration: advance configuration of freezing transaction time, freezing transaction type, and whether the freezing command can be withdrawn; when the user realizes that the private key has been stolen, the freezing operation will be triggered immediately to help the user further reduce losses.
    Capture account authority configuration: configure in advance N friend addresses and M for friend operations to take effect; when the user realizes the private key has been stolen, let the account freeze first and contact their friends as soon as possible. When more than M friends vote to pass, the authority of the stolen account will be taken over and any transaction will be executed only after N friends vote. This way even if the hacker steals the private key, he will not be able to transfer money effectively.
    2.Active_Alarming PalletWe will provide users with on-chain and off-chain alerting functions. This module will be implemented through Substrate Pallet:
    On-chain alarm configuration: Any transaction that exceeds the limit will send an alarm event; for example, the user can configure that when N transactions exceeding the limit amount occur within a period of time, an off-chain alarm notification will be triggered; the user can configure, a period of Within a certain time, different times will trigger different alarm methods.
    Off-chain triggering alarms: Provide users with three off-chain notification methods: Mail, Slack, and Discord. For example, general alarms are sent to Mail, important alarms are sent to Slack, and critical alarms are sent to Discord to achieve hierarchical management of alarms.

    1.Analyzer ModuleWe will provide users with off-chain transaction analysis functionality, and this module will be implemented via the Go/Python programming language๏ผš
    Users can choose whether to enable the off-chain transaction analysis function. The module records and analyzes user transaction characteristics based on a counter, and uploads to the blockchain when abnormal results emerge from the analysis. When a potentially abnormal transaction occurs, the user can choose, based on advance configuration, whether the module simply alerts when an abnormal transaction is reported, or freezes the account until the user comes to deal with the problem on their own. In this case, the hacker does not trigger any on-chain restrictions, only the off-chain transaction analysis detects the anomaly
    2.Tracker ModuleWe will provide users with off-chain transaction analysis functionality, and this module will be implemented via the Go/Python programming language.
    This module implements the function of tracking the transaction records of a certain address at a certain time period, helping users to assist in analyzing the loss of the current address from the hacking attack, as well as analyzing the chain through which the hacker transferred the funds.

    Future Plansโ€‹

    Conceptualizing the application with the trigger concept, implementing the transaction firewall first, and refining our design based on user feedback. Implementation steps.

    • develop on-chain/off-chain triggers for firewall requirements.
    • refining the firewall design based on user feedback.
    • implementing cross-chain transactions and providing transaction protection for cross-chain links.
    • configure different levels of defense strategies based on implementation experience.

    Project Overview ๐Ÿ“„โ€‹

    This application is not in response to an RFP, but it fully complies with a potentially interesting project โ€œSign-in with your Polkadot, Kusama, etc. accountโ€ mentioned in Open Source Polkadot Stack page in the โ€œ browser extensionsโ€ section.

    Overviewโ€‹

    Remembering passwords from all resources is a challenging task. It doesnโ€™t need any introduction as all Internet users use passwords dozen times a day. The most common, but less reliable way of password managing is using the only password for all resources โ€“ not a good idea, but true. The other one, next most popular โ€“ using password managers built in your browser. Quite reliable for low critical data, but for privacy critical data this is not the way to store passwords as there are several ways for third parties to obtain passwords from these centralized systems. Users that value privacy usually use offline desktop applications for managing passwords โ€“ itโ€™s safe, but has disadvantages as different devices wonโ€™t sync, so one has to manage them separately.

    The aim of this project is to develop a decentralized password manager that stores data in a blockchain and uses personal Polkadot wallet credentials to access the passwords manager dApp. Saved passwords will be added automatically to appropriate forms on websites after logging in with userโ€™s wallet private key in the browser extension.

    Project Detailsโ€‹

    The Rubeus Keeper dApp will consist of two functional modules:

    1. An Ink! smart contract for seัure password storage using a Polkadot or Kusama account. Just log in to your Polkadot wallet and get access to your passwords DB. The smart contract will includes methods for writing and getting passwords, as well as categorizing.
    2. A browser extension for password managing: registration, log in, password generation, categorizing, saving, retrieving, autocomplete functionality.

    Under this MVP we consider security in the next attack vectors:

    1. Transferred data unauthorized interception and decryption (categories, URLs/logins, passwords).
    2. Malicious data substitution by a node. To solve the above mentioned tasks the data will be encrypted using the ChaCha20-Poly1305 streaming algorithm with message authentication. The protocol is standardized by IETF in RFC 7539, in software implementations it is much more efficient and faster than AES.

    Rubeus schema 3

    Ecosystem Fitโ€‹

    The Rubeus Keeper dApp will be used by all the community and even all Internet users as it simplifies and secures daily interaction with web applications โ€“ web2 or web3 โ€“ our dApp will be comprehensively useful. The target audience is โ€œa web userโ€.

    In the Open Source Polkadot Stack we see the Logion network project, that represents a separate parachain with very wide functionality. Unlike Logion we offer a simple Ink! contract and an extension that can be used in any Substrate based parachain with no need for setting nodes and etc. Fast, easy and no need for a separate wallet.

    Milestone 1 โ€” Implement Cryptographic Modulesโ€‹

    The main deliverable of this milestone includes:

    0a.LicenseApache License 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes. Once the node is up, it will be possible to send test transactions that will show how the new functionality works.

    1.Cryptographic modulesWe will implement the cryptographic modules including inner product functional encryption and quadratic polynomial functional encryption [MSHBM2019] and the associated zero-knowledge proof [ZeroPool]. The cryptographic modules will be written in Rust and modified from the rust version of CiFEr library. We will build privacy-preserving classification and neural networks based on these modules. We will also implement a substrate pallet that integrates the verification logic of the associated zero-knowledge proof for the legitimacy of the encrypted functional key.
    2.BenchmarkPerform unit tests on the individual algorithms to ensure their safety. Benchmark on the gas cost and throughput of the proposed module.
    3.DockerWe will provide a dockerfile to demonstrate the usage of our modules.

    Milestone 2 โ€”โ€” Client Implementation and Integrationโ€‹

    The main deliverable of the milestone is the client that can trigger the aforementioned cryptographic modules and the micropayment scheme and the necessary UI to enable the users to interact with all these algorithms.

    1.Client modulesWe will implement the client to support the key distribution and decryption of the functional encryption scheme [MSHBM2019]. The client will also generate the transaction that can trigger the aforementioned cryptographic modules and the micropayment scheme [MDJM2019], such as the encrypted functional key and zero-knowledge proof. We will provide a basic UI to take inputs from the users for all these algorithms and receive the outputs. More specifically, the UI will enable the data owner to input the raw data to generate the signed ciphertext and upload it to the cloud server. The UI will also allow the data purchaser to retrieve the functional key from the key authority and the ciphertext from the cloud and then perform the decryption. The UI will also register a qualified data source and allow a data owner to join the data monetization program when he/she meets the data source and the data owners to request a signature from a registered source, which will then be verified on-chain. Finally, it will also allow these entities to interact with the substrate module with the inputs and outputs defined in our architecture.
    2.BenchmarkPerform unit tests on the individual algorithms to ensure their safety. Benchmark on the latency and usability of the proposed client functionalities.
    3.DockerWe will provide a dockerfile to demonstrate the usage of our modules.

    Community Engagementโ€‹

    Future Plansโ€‹

    We will hire at least 8-10 more devs in the next three months. Meanwhile, we will apply for the Substrate Builder's Program. After that, Ruby Protocol wants to become a parachain for the Polkadot network. We have some preparations for auction and we may design a community-wide LPO.

    In phase 1, we will complete the implementation of cryptographic modules as a substrate pallet that integrates the verification logic of the associated zero-knowledge proof for the legitimacy of the encrypted functional key.

    In phase 2, our goal is to deliver the micropayment scheme and enable the users to interact with all these algorithms in a working product.

    Finally, our goal is to provide an essential open API and SDK from a high-level perspective with the above tools, fully powering the data monetization framework on Polkadot.

    Overviewโ€‹

    Summary: SaaS3 is a protocol in layer2 that is highly scalable, crypto incentivized, and results in a solution that can serve as a decentralized APIs (dAPI) middleware to provide off-chain services to blockchain smart contracts.

    Brief Introductionโ€‹

    Background

    Dilemma of web3 Ecosystem - With functionalities yet to become full-fledged, Web3.0 applications need a rethink of development stacks. For instance, most of the web2 projects and dependencies are based on Java, C++, PHP, etc., while web3 requires another totally different technical stacks such as Solidity, Motoku, or Substrate on EVM / WASM which hinders web2 developers to build web3 applications.

    Our solution - SaaS3 Oracle

    SaaS3 aims to deliver a highly scalable, crypto token incentivized and fully decentralized software as a service (SaaS) network which results in a solution that allows anyone to define and deploy customized oracles according to their Dapp needs. SaaS3 is devoted to transforming traditional web2 API to web3 dAPI.

    Essentially, SaaS3 is an TEE powered oracle infrastructure that allows anyone to define and deploy custom oracles according to their Dapp requirements. SaaS3 utilizes TEE technologies, while still enabling decentralization, trustless and secure computation by the secure hardware guarantee of Intel SGX chipset designs and by delegated proof of stake (DPoS) consensus.

    Therefore, such an infrastructure is not only for oracles that provide data feeds but also any type of computation which requires safe exchange of data.

    Examples:

    1. Any data feed:
      • Price of assets (ERC20/NFTs) on CEX and DEX.
      • Random Numbers
      • Weather reports, price of rent of an apartment, supply chain data, FIFA match results...
    2. Cross-chain data:
      • Bridges and cross-chain relayers
    3. Computation
      • Decentralized off-chain computation to enable truly decentralized metaverses and games
    4. Any Dapp that requires trust:
      • Custodian account managed by TEE for GameFi users that allows them to interact with the blockchain with only web2 api requests.

    SaaS3 enables Dapps to become as versatile as any other web2 application available today on the internet. As a result, the SaaS3 project will bridge web2 APIs to web3 dAPIs to flourish web3 ecosystem and achieve creator economy in a decentralized and trust-minimized way. This grant will allow us to develop several ink! smart contracts and a pallet for DAO management.

    Integration into Polkadot / Kusamaโ€‹

    • We planned to developed a parachain on Polkadot as SaaS3 DAO multichain governance centers.

    • The major component dRuntime will be implemented in ink!. https://github.com/SaaS3-Foundation/dRuntime-fat

    • Collaboration with Phala Network: We have partnered up with Phala Network which is a prominent parachain on the Polkadot ecosystem who will be providing SaaS3 with 15,000+ active TEE miners to enable trustless, permissionless and secure computation for our oracle infrastructure.

    Team Motivationโ€‹

    Our team has rich experience in web3 ecosystem, and we are dedicated to achieve secure and decentralized oracles.

    Protocol Detailsโ€‹

    Technology Stackโ€‹

    • Substrate
    • TEE
    • gRPC
    • Rust

    SaaS3 Protocolโ€‹

    SaaS3 protocol constructs a permissionless oracle network (PoN) to eliminate centralized computation resources to deliver developers the ability to create their customizable oracle (dAPI) by one-click permissionlessly and hostlessly.

    Permissionless Oracle Network (PoN)

    In PoN, four roles are involved: creator, miner, staker, and requester, and each role should accommodate SaaS3 protocol to stake and contribute to maintaining the high-quality services as shown in the following figure.

    Screenshot 2022-11-12 at 4 41 30 PM
    • Creator is the role of submitting dRuntime to create an oracle (dAPI) service, who can be any kind of off-chain service providers such as crypto exchanges, events organizers, or software developer.
    • Staker is anyone participating in the delegated proof of stake (DPoS) mechanism.
    • Miner acts as the computational worker to execute dRuntime on the hardware. TEE workers in Phala Network will be adopted in SaaS3 ecosystem to undertake this critical mission.
    • Requester calls the SaaS3 protocol to request off-chain services such as particular data feeds or off-chain computation results.

    Decentralized Serverless Runtime (dRuntime)

    In SaaS3, dRuntime (Decentralized Serverless Runtime) is a concept against centralized deployed runtimes which are centralized on cloud computing servers. dRuntime can be deployed on miner networks in a decentralized way by SaaS3 oracle launchpad. The launchpad is a Dapp for oracle creators to create their oracle with one click. Particularly, the creators should integrate the dAPI programs and settings into the dRuntime on the launchpad. Therefore, one oracle can be executed by multiple miners to achieve off-chain services instead of trusting an off-chain single point.

    There are four phases for dRuntime execution:

    1. Request: The Dapp smart contracts will call the protocol contract to request a specific off-chain service. The protocol contract will record the request specifications in blockchain event logs.
    2. Filtering: For each on-chain request, the protocol will generate a lightweight PoW (LPoW) task. The miners will compete to win the execution permissions by solving the LPoW task. The fastest 3 miners will win the execution permissions to run the API. Besides, the winners should be in the top-100 stake list, in other words, they should have a good amount of token stakes.
    3. Execution: The 3 winners in the last phase execute the corresponding API to retrieve the off-chain services.
    4. 3-zkc: An on-chain verification is performed with three minersโ€™ responses to aggregate the final output with the reward/slash on miner stakes.

    Architectureโ€‹

    SaaS3 architecture
    • Target Chain: SaaS3 protocol will be deployed on multiple blockchains, such as Polkadot and Kusama.
      • Dapp: decentralized applications which adopt SaaS3 oracle.
      • SaaS3 Protocol: a proxy smart contract which accept requests from Dapp and push them to Phat Rollup Anchor.
      • Phat Rollup Anchor: a smart contract built by Phala Network. It performs offchain rollup and commuicates to a phat contract dRuntime. Repo: https://github.com/Phala-Network/phat-offchain-rollup
    • SaaS3 Launchpad: a web-based Dapp which allows oracle creators to one-click launch their customizable oracle hostlessly and permissionlessly. By using Factory contract, oracle creators can deploy dRuntime phat contract easily.
    • Phat contract: the innovative programming model enabling off-chain computation which is created by Phala Network. Itโ€™s also known as Fat Contract as a practice of the "Fat Protocol and Thin Application" concept, and for its rich functionalities compared with existing smart contracts. Phat Contract uses Rust-based ink! language.
      - Offchain Scheduler: a phat contract built by Phala Network.
      - dRuntime: dRuntime (Decentralized Serverless Runtime) is a concept against centralized deployed runtimes which are centralized on cloud Computing servers. It can be deployed on miner networks in a decentralized way by SaaS3 oracle launchpad.
    • Phala Workers: are the TEE computation nodes with intel SGX chips which provide a hardware-encrypted sandbox for program executions with privacy-preserving and trustful computations.
    • Web2: includes all web2 services which provide API services, such as pricing reporting, event news, graph rendering and deep learning.

    Private Oracleโ€‹

    Phala network is exploited in SaaS3 as a decentralized computational infrastructure with hardware-encrypted TEE chips. Trusted Execution Environment (TEE) is a special area in some processors that provides a higher level of security including isolated execution, code integration, and state confidentiality. Thus, the oracle creators can easily store the API key or private data inside the fat contract which cannot be leaked out or be visible to miner operators.

    Private oracle is a particular kind of dAPI that only can be requested by the oracle creators themselves. Regardless of public oracles which only provide public data feeds, there is a large market for private oracles to connect blockchains with private off-chain services. To our knowledge, SaaS3 is the first oracle platform to support private oracle setup with a high-security architecture and one-click fast development.

    SaaS3 DAOโ€‹

    SaaS3 DAO refers to the decentralized autonomous organization (DAO), a governance body established with a full-fledged mechanism for token economics.

    Since the SaaS3 protocol will be deployed on multiple blockchains, each blockchain should have its own SaaS3 DAO. To manage different DAOs among multiple blockchains, SaaS3 will launch a Polkadot crowdloan to register a dedicated SaaS3 DAO parachain. The following figure demonstrates the multi-DAO structure.

    Multi-DAO Structure

    Treasury

    Each SaaS3 DAO has a treasury to maintain a pool of tokens that come from the commissions of dAPI subscription fee, and malfunction scrutiny and are designated funds for court jury rewards, protocol maintenance, and other DAO events.

    DAO treasury receives tokens when:

    • An oracle malfunctions due to inherent design flaws.
    • A miner node malfunctions due to miner dishonesty.
    • For each successful fulfillment of a dAPI subscription, the treasury receives a commission from a portion of the subscription fee payable by the user.

    For each court ruling, the treasury sends to the Jury as a reward for their participation in the governance. Since SaaS3 protocol is a multi-chain deployment, SaaS3 DAO parachain on Polkadot has the largest treasury to manage other treasuries among multiple blockchains.

    Court DAO

    A court as a component of a decentralized autonomous organization has been adopted as a medium of governance to consolidate consensus, justify DAO legitimacy and improve governance.

    On the Court DAO, there is a team of Jury members, consisting of 101 API creators that contribute most to the SaaS3 ecosystem which can be quantized by their API earnings. The court DAO receives the lawsuit from suing actors, composed of users and miners. The Jury members will make a judgment on the lawsuit by voting. If the suing actors win the lawsuit, the entities being accused will be penalized, the suing actor will be compensated for their loss and Jury members will be rewarded for their contribution to the case.

    Court DAO is charged with settling disputes regarding the performance of dAPI to hold dishonest actors accountable. Where there is a dAPI user who experiences a dAPI malfunction and fills a claim at Court DAO for scrutiny, Court DAO commences processing the case. Court DAO is seated by a group of jury members, who receive rewards for rulings. Rulings at Court DAO result in two outcomes; either the party who has filed the claim wins and the liable party has their staked tokens slashed, or the claim is dismissed.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

      • SaaS3 provides a native and secure oracle solution to Dapps, empowering all DeFi projects in Polkadot / Kusama ecosystem.
      • SaaS3 holds potential for interaction with other parachains of Polkadot / Kusama such as Phala(Oracle Miner) and Moonbeam(Oracle User).

    • Target Audience: Dapp developers and parachain developers. SaaS3 oracle allows them to define and deploy customized oracles according to their Dapp needs.

    • What need(s) does your project meet?

      • Although web2 applications are highly dependent on centralized libraries and technical stack, they have a potential case of monetization if migrated to web3 as decentralized web3 dAPI through SaaS3 protocol.
      • SaaS3 brings millions of Dapp users, providers of computing resources and creators into a harmony and an organic ecosystem, with lowered costs and reliable services.
      • SaaS3 facilitates the privacy computation and TEE adoption in web3.

    • Compared to similar projects:

      • In Substrate / Polkadot / Kusama ecosystem:

        • Kylin Network: It offer less secure oracle solution, and its oracle nodes are neither permissionless nor decentralized .

      • In related ecosystems:

        • Chainlink: It is not dynamic, and it is hard to create customized oracle. Also, it does not have decentralized computation.
        • API3: Permission and centralized host server required.

    2.aDevelopmentBuilding a prototype that improves over the development of Milestone 1 of ScoutCoinFabrik PoC, detecting more classes of vulnerabilities and improving in precision on existing detectors. We are to build a prototype that can analyze Rust code to detect vulnerabilities in ink! smart contracts and possibly in pallets and other pieces of code. This builds over this proof-of-concept tool we've built and delivered as part of a grant for the web3 foundation by:
    a) Moving from a proof-of-concept (PoC) tool to a robust tool that integrates with a popular IDE (VSCode), includes a CLI, etc,
    b) We will improve on the precision of the detectors we included in the PoC reducing the rate of false positives, and
    c) We will add more detectors in order to have a reasonable coverage of the relevant security vulnerabilities that happen in smart contracts.
    2.bDevelopmentCommand line interface for the prototype. For this prototype, we want to develop a simple command line interface like the one used in other static analyzers from other blockchains (eg: Slither, Rustle).
    In particular, we will develop the possibility to run the prototype on smart contract files or directories.
    The base command will be: cargo scout file_name.rs
    We will also include options for running subsets of detectors and triggering errors for CI/CD workflows.
    2.cDevelopmentVSCode integration for the prototype. Our VSCode development will list security issues, highlight issues with squiggles and hover-over descriptions. We will seek compatibility of this development with other relevant ink! extensions such as Ink! Analyzer.

    Project Overviewโ€‹

    Overviewโ€‹

    Societal is an all-in-one Decentralized Autonomous Organization (DAO) creation and management platform. Societal allows all types of groups or communities to build their own online, transparent, and decentralized organization. Societal bundles all of the tools required to create and manage a DAO in one place. Creators will be empowered to construct a DAO with fungible, non-fungible, or a combination of governance tokens. Societal also offers DAO management tooling features like treasury management, specialized governance, task boards, legal structuring, and accounting. This removes the need to utilize siloed platforms to manage the operations of a DAO. Whether a creator is looking to build a DAO for their organization, raise and deploy investment capital, or decentralize governance of an NFT project, Societal has the necessary tooling for a seamless end-to-end experience.

    Utilizing Polkdaotโ€™s layer-0 infrastructure and ecosystem, Societal will provide DAOs with both maximum functionality and a cohesive user experience. With features including agnostic token compatibility, zero gas fees, a freemium entry point, and a SaaS-based membership pricing, Societal combines best-in-class features into one vertically integrated product. With integrations into DeFi, privacy, and identity protocols, Societal will enable web3 organizations to seamlessly transition and manage their DAOs into the future.

    The Societal team has been building in the Polkadot ecosystem for the last year. While at a previous Polkadot project, the Societal team noticed a lack of integrated DAO tooling - not only in the Polkadot ecosystem, but in the broader web3 industry as a whole. After analyzing how we might transition and manage our previous project into a DAO, there was no clear path. This, along with the team being both members and council members of various DAOs and noticing the lack of infrastructure, we decided to build a solution - Societal.

    Societal Labs has been designing the product vision of the Socital platform for quite some time. We will go over the project details and blockchain architecture in this application and provide references below for more in-depth context.

    In Societal's final state, it will offer four main services; Create, Transition, Transfer and Manage. Create will allow any web3 user to create their own DAO. Transition will allow protocols to progressively move towards community ownership. Transfer will allow DAOs to transfer their DAO from an expensive siloed chain to the Sociteal platform. Manage will provide DAOs all the required product features to manage their organization, whether it is a small investment club or a large community-governed protocol.

    Societal will offer a wide range of features to create and manage a DAO. The features are split into three categories; Operations, Treasury, and Governance. The Operations features are: job & task boards, payroll, customizable feeds, legal tooling, on-chain reputation, and web & mobile application. The Treasury features are as follows: treasury wallets (multi-sig), DeFi integrations, on-chain cap table, accounting and private asset integrations. The governance features are: zero gas fee governance, proposal calendar, built-in governance models, governance treasury execution, and private voting.

    Societal will vertically integrate with projects to advance its tech stack and product offering, something not seen in most web3 projects today. For example, Societal can integrate DeFi services by working with projects like Acala, Parallel, and Composable Finance, which will allow for active treasury management for DAOs managed with Societal. For private assets and voting, projects like Manta and Phala can provide privacy-enabling functions like zero-knowledge proofs and trusted execution environments to make this possible. For on-chain credentials, projects like KILT and Litentry can provide KYC and member credentialing services that can be used by DAOs for governance and recruiting.

    The Societal platform will host a vast network of DAOs and eventually offer a Cross-DAO Marketplace. DAOโ€™s onboarded onto the platform will have access to a network of individual DAOs, along with any associated sub-DAOs or guilds. When a DAO has a task that needs to be completed, they will have the ability to post this task to the entire Societal network. This will reach the collective network of sub-DAOs or guilds that may have the ability to complete the required work. The interconnection of DAOs on the Societal platform will open up never before seen opportunities in collaboration across the web3 DAO, sub-DAO, and guild ecosystem.

    Finally, Societal plans to progressively transition into a DAO itself. Once the token is launched, a community-run treasury will grow over time until the entire network is owned and operated by the community.

    Ecosystem Fitโ€‹

    As it stands today, the DAO landscape within the Polkadot ecosystem is not as mature as other ecosystems such as Ethereum and Solana. This is due to insufficient DAO creation and tooling infrastructure in the ecosystem. Currently, the Polkadot ecosystem does not have the creation, governance, treasury management, and payroll tooling products as other major blockchains. By building these tooling products on Polkadot, both the Polkadot DAO landscape and the broader DAO management tooling space is primed for innovation by utilizing the unique technical abilities that Substrate provides.

    The target audience of the Societal application are web3 users who require a platform to easily create and manage their DAO. Using the technical capabilities that Substrate provides, Societal will design our chain to be token agnostic, allowing current MetaMask users to easily connect to our chain and start using the governance application right away. By doing this, our project will meet the needs of the Polkadot community to create their own DAOs and have the tools to manage them as seen in other ecosystems.

    The projects like Societal in the Polkadot space are Polkassembly, SubDAO, and DoraFactory. Societal differs from these projects in multiple ways. First, Polkassembly is not building their own parachain and is only a governance platform for large Polkadot projects. Societal wants to allow any web3 user to create their own DAO - not just catering to large established protocols. SubDAO has recently been focusing on smart contract deployments on multiple chains and does not appear to be building a parachain. Societal will build its own parachain and use the technical capabilities of Substrate to be truly token agnostic, connecting with widely used wallets such as MetaMask, to avoid doing multiple chain deployments via smart contracts. Dora Factory is similar to Societal in the sense that they are building their own parachian, however we plan to offer zero gas fees and a SaaS based pricing model to enhance our user's experience. Societal will also seek to integrate with other parachains, having cross-chain smart contract execution.

    Future Plansโ€‹

    Societal plans to secure fundraising and expand the development team. After the completion of the milestones stated above, Societal plans to expand the product offering by implementing a DAO Market Place and a Mobile App for DAO management. Ideally Societal will be able to secure another Web3 grant for these milestones, along with integrations for private voting and identity voting based on links to the RFPs. From there, Societal would also like to apply for the Substrate Builders Program, establishing itself at the go to DAO and governance platform. Finally, Societal will progressively transition into a DAO itself and release control to the community.

    Our target audiences are Web3 projects and starting/current blockchain developers.

    As SDK is also fully developed and its metrics are available to the public we can see, that it is still used a lot by developers in the ecosystem (Even after the API release).

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    As a synthetic asset protocol,Standard protocol heavily depends on the oracle for maintaining the system. Oracles should be formed in a sustainable way to be motivated for people to provide computing power. To reward the network participant, Standard protocol proposes new PoS reward system by splitting block rewards from block validators to oracle providers.

    Milestone 1 - Middleware for data submission and runtime integrationโ€‹

    This milestone focuses on building a oracle provider client middleware which submits off-chain data to the blockchain. An authoritive module for testing connection between oracle provider and the protocol is provided in this phase. Then, Standard will extend the oracle module to distribute reward from session callback connected between pallet_session and pallet_staking. When oracle provider submits outliers or does not submit values that are out of sync from other oracle providers, a slash can be applied from anyone to report. Outliers are detected with IQR method.

    Oracle provider clientโ€‹

    As chainlink and other oracle solution has a middleware or submitting client from off-chain, Standard also has its oracle client. Oracle provider client is actually a bot that uses polkadot-js api to submit information in oracle module in a certain periods(e.g. 2 hour, 4 hour). For example, to send an oracle xt from an oracle client,

    // Loads config
    import LumenConfig from "@digitalnative/lumen-config";
    // Fetch functions for acquiring off-chain data
    import fetchData from "@digitalnative/lumen-fetch";
    // Submit function for submitting data to on-chain
    import submitData from "@digitalnative/lumen-submit";
    // Async Apis for polkadot
    import { ApiPromise, WsProvider } from "@polkadot/api";

    const runClient = async (dir) => {
      const cron = require("node-cron");
      const config = LumenConfig.default({ dir });
      const { events } = config;
      events.emit("client:start");
      const api = await polkadotApi(config);
      // register cron job to execute in every minute
      cron.schedule("*/90 * * * * *", async function() {
        events.emit("client:next");
        // fetch data
        const data = await fetchData(false, config);
        // Submit data
        await submitData(data, config, api);
      });
      // Declare cron job has been set
      events.emit("client:init");
    };

    export default runClient;

    async function polkadotApi(config: LumenConfig) {
      const provider = new WsProvider(config.rpc);
      const definitions = require("@digitalnative/type-definitions/opportunity");
      let types = definitions.types[0].types;
      const api = await new ApiPromise({
        provider,
        types,
      });
      await api.isReady;
      return api;
    }

    Here is the overall workflow for the client operation, and add-ons and options are expected to be added in each function in the library.

    Unit testsโ€‹

    Standard protocol applies test driven development(TDD) on building runtime modules for the grant. Here are unit tests that will be done along the development in the runtime module.

    Oracleโ€‹

    oracle in milestone 1 should achieve:

    To check this, oracle provider module should have these test functions:

    4.Npm binaryWe will provide a npm binary for oracle providers to install and run an oracle client
    5.DockerfileDockerfile for running Standard protocol binary will be provided

    Milestone 2 - PoS oracle reward distributionโ€‹

    This milestone focuses on including session callbacks related to sessions in implementations of SessionManager trait in pallet-staking module, and all related module will be tested with its separate implementation of SessionManager connected to pallet-session in a mock environment.

    Vaultโ€‹

    Vault in milestone 2 should have a trait for dependency Injection:

    pub trait RebaseCallback {
        fn rebase(); // where it initiates rebase in the session
    }

    The dependency injection will take place in the pallet-staking's config as well as the oracle

    impl pallet_custom_staking::Config for Runtime{
        ...
        type Rebase = RebaseCallback; // for vault rebase
        type Oracle = OracleCallback; // for oracle callback used as same as staking callbacks
    }

    where the it will be included in pallet-staking module's SessionManager trait implementation in end_session function like:

    /// In this implementation `new_session(session)` must be called before `end_session(session-1)`
    /// i.e. the new session must be planned before the ending of the previous session.
    ///
    /// Once the first new_session is planned, all session must start and then end in order, though
    /// some session can lag in between the newest session planned and the latest session started.
    impl<T: Config> pallet_session::SessionManager<T::AccountId> for Module<T> {
     fn new_session(new_index: SessionIndex) -> Option<Vec<T::AccountId>> {
      frame_support::debug::native::trace!(
       target: LOG_TARGET,
       "[{}] planning new_session({})",
       <frame_system::Module<T>>::block_number(),
       new_index
      );
      Self::new_session(new_index)
     }
     fn start_session(start_index: SessionIndex) {
      frame_support::debug::native::trace!(
       target: LOG_TARGET,
       "[{}] starting start_session({})",
       <frame_system::Module<T>>::block_number(),
       start_index
      );
      Self::start_session(start_index)
     }
     fn end_session(end_index: SessionIndex) {
      frame_support::debug::native::trace!(
       target: LOG_TARGET,
       "[{}] ending end_session({}) with rebase",
       <frame_system::Module<T>>::block_number(),
       end_index
      );
                    T::Rebase::rebase();
      Self::end_session(end_index)
     }
    }

    vault in milestone 2 should achieve:

    To check this, vault module should have these test functions:

    Oracleโ€‹

    oracle will replicate the pallet-staking module regarding election of the oracle provider and the reward logic. However, there will be difference in how the elected provider(or validator) is allocated to the slot. The module only accepts the stash account to submit oracle data once validate() tx has been finalized.

    For example, there will be addition in the select_and_update_validators function code

    /// Select the new validator set at the end of the era.
     ///
     /// Runs [`try_do_phragmen`] and updates the following storage items:
     /// - [`EraElectionStatus`]: with `None`.
     /// - [`ErasStakers`]: with the new staker set.
     /// - [`ErasStakersClipped`].
     /// - [`ErasValidatorPrefs`].
     /// - [`ErasTotalStake`]: with the new total stake.
     /// - [`SnapshotValidators`] and [`SnapshotNominators`] are both removed.
     ///
     /// Internally, [`QueuedElected`], snapshots and [`QueuedScore`] are also consumed.
     ///
     /// If the election has been successful, It passes the new set upwards.
     ///
     /// This should only be called at the end of an era.
     fn select_and_update_validators(current_era: EraIndex) -> Option<Vec<T::AccountId>> {
      if let Some(ElectionResult::<T::AccountId, BalanceOf<T>> {
       elected_stashes,
       exposures,
       compute,
      }) = Self::try_do_election() {
       // Totally close the election round and data.
       Self::close_election_window();

       // Populate Stakers and write slot stake.
       let mut total_stake: BalanceOf<T> = Zero::zero();
       exposures.into_iter().for_each(|(stash, exposure)| {
        total_stake = total_stake.saturating_add(exposure.total);
        <ErasStakers<T>>::insert(current_era, &stash, &exposure);

        let mut exposure_clipped = exposure;
        let clipped_max_len = T::MaxNominatorRewardedPerValidator::get() as usize;
        if exposure_clipped.others.len() > clipped_max_len {
         exposure_clipped.others.sort_by(|a, b| a.value.cmp(&b.value).reverse());
         exposure_clipped.others.truncate(clipped_max_len);
        }
        <ErasStakersClipped<T>>::insert(&current_era, &stash, exposure_clipped);
       });

       // Insert current era staking information
       <ErasTotalStake<T>>::insert(&current_era, total_stake);

       // collect the pref of all winners
       for (i, stash) in elected_stashes.iter().enumerate() {
                    <Slots<T>>::insert(i, stash.clone()); // allocating slots for elected oracle provider
        let pref = Self::validators(stash);
        <ErasValidatorPrefs<T>>::insert(&current_era, stash, pref);
       }
                

       // emit event
       Self::deposit_event(RawEvent::StakingElection(compute));

       log!(
        info,
        "๐Ÿ’ธ new validator set of size {:?} has been elected via {:?} for era {:?}",
        elected_stashes.len(),
        compute,
        current_era,
       );

       Some(elected_stashes)
      } else {
       None
      }
     }

    Also, slash module function should include verifier from milestone 1.

    /// Slash the validator for a given amount of balance. This can grow the value
     /// of the slash in the case that the validator has less than `minimum_balance`
     /// active funds. Returns the amount of funds actually slashed.
     ///
     /// Slashes from `active` funds first, and then `unlocking`, starting with the
     /// chunks that are closest to unlocking.
     fn slash(
      &mut self,
      mut value: Balance,
      minimum_balance: Balance,
            slot: SlotIndex,
     ) -> Balance {
      let batch = Prices::get(_id).unwrap();
      let value = batch[_slot as usize];
      let det = Self::determine_outlier(batch, value);
      ensure!(det, Error::<T>::NotOutlier);
      let pre_total = self.total;
      let total = &mut self.total;
      let active = &mut self.active;

      let slash_out_of = |
       total_remaining: &mut Balance,
       target: &mut Balance,
       value: &mut Balance,
      | {
       let mut slash_from_target = (*value).min(*target);

       if !slash_from_target.is_zero() {
        *target -= slash_from_target;

        // don't leave a dust balance in the staking system.
        if *target <= minimum_balance {
         slash_from_target += *target;
         *value += sp_std::mem::replace(target, Zero::zero());
        }

        *total_remaining = total_remaining.saturating_sub(slash_from_target);
        *value -= slash_from_target;
       }
      };

      slash_out_of(total, active, &mut value);

      let i = self.unlocking.iter_mut()
       .map(|chunk| {
        slash_out_of(total, &mut chunk.value, &mut value);
        chunk.value
       })
       .take_while(|value| value.is_zero()) // take all fully-consumed chunks out.
       .count();

      // kill all drained chunks.
      let _ = self.unlocking.drain(..i);

      pre_total.saturating_sub(*total)
     }
    }

    Unit test

    Unit tests are all identical with the staking module's test in that all logics are identical regarding slash, reward and validation.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    It is well known that most NFTs are traded either directly or by auction, and the single NFT limit the flexibility of NFTs in some ways.

    Splittable NFT will bring liquidity, lower barriers to entry and more possibilities to NFT ecosystem. For example, buying SubNFTs on bonding curve will allow for better pricing of works, while NFTs that are otherwise very expensive can be collected by more people, it is also possible to purchase a group of NFT tokens and contribute to the management of this group of NFTs.

    Starry provides some solutions for splittable NFTs, such as: splitting Single NFT into some SubNFTs, splitting Single NFT into some fungible tokens, and splitting a group of NFTs into some fungible tokens and managing them using dao.

    Project Detailsโ€‹

    The Starry Protocol contains four parts: Pallet_NFT, Pallet_SubNFT, Pallet_EX, Frontend

    Architectureโ€‹

    Pallet_SubNFT

    An NFT Wrapper to split NFTs into SubNFTs or fungible tokens, or a set of NFTs into fungible tokens( without DAO). Here is demo page.

    Pallet_NFTDAO

    Split a set of NFTs into fungible tokens and manage the NFTs in a DAO way, such as adding more NFTs or selling NFTs. Here is demo page.

    Pallet_EX

    exchange NFT (including buying SubNFTs with bonding curve/one price) and send royalties generated by each transaction to the creator. Here is demo page.

    FrontEnd

    Interaction with users. Here is a demo

    Additional Information โž•โ€‹

    • What is the difference between SubNFT and Erc-1155?

      erc-1155's multiple NFT is Semi-fungible tokens, these tokens use same token_id.

      SubNFT splits single NFT into different NFTs, each SubNFT has its own token_id. As a result, subNFT is even rarer and suitable as a collector's item.

      For example, we can use Semi-fungible tokens to create general admission tickets for a concert, and then use SubNFT to create commemorative tickets.

    • What is the difference between SubNFT and Erc-721?

      subNFT is also erc-721 token

    • Perhaps you may be confused with how nft dao works, here is an example to explain it:

      Alice created the token named DOGE with a set of NFTs related to the Doge meme, but she did not want to manage this set of NFTs herself, so Alice created the Doge NFTS DAO.

      Bob was very happy with Doge and created NFT related to Doge, at this time he saw Doge NFTS DAO, so he thought it would be a great thing to put his work into this DAO, so he launched a proposal with this NFT and hoped to get 2000 DOGE in return.

      Charlie likes Doge-related NFTs and holds many DOGE. One day, Charlie saw an NFT that he thought would be helpful for the appreciation of DOGE, so he bought it on Starry and then initiated a proposal in DAO to add the NFT and hoped to get 1500 DOGE to make up for the loss (of course he could have done without the 1500 DOGE).

      Dave was an active participant in the Doge NFTS DAO and when he looked at the proposals he saw Bob and Charlie's proposals and thought they were great proposals, so Dave used a certain DOGE to agree to both proposals.

      Since most people agreed with Bob and Charlie's proposal, the proposed NFTs were added to the NFTs managed by the DAO and the corresponding DOGEs were minted for Bob and Charlie.

    StorageHub Grant Application

    • Team Name: Moonsong Labs
    • Payment Address: USD Wire Preferred
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • Tagline Describer

      • StorageHub is a decentralized storage public good parachain optimized for file based storage and larger data sets that are not suitable to be stored directly in standard parachain storage. The proposed parachain will provide developers in the Polkadot ecosystem with an alternate decentralized and substrate-based storage solution and functionality.

    • Purpose

      • The goal of this project is to provide storage for web3 applications and protocols within the Polkadot & Kusama ecosystems. Unlike other storage protocols that focus on end user or enterprise storage scenarios, StorageHubโ€™s feature set optimizes for web3 application storage use cases. StorageHub aims to provide a decentralized storage option that allows web3 applications to store large files and large data sets in a cost efficient way without sacrificing decentralization properties.

    • Problem

      • Storage oriented chains, like Filecoin and Arweave, have emerged to provide more efficient and decentralized storage capabilities. However, these chains are standalone chains, and are not designed to interoperate with other chains. The problem is that web3 apps need smart contract logic and compute to be combined with storage to make a complete solution, but smart contracts and compute generally reside on different chains (e.g. Ethereum Mainnet, L2 rollups, Parachains) vs. on the storage optimized chains (Filecoin, Arweave). In response, these storage chains have tried to bolster their smart contract capabilities (e.g. Filecoinโ€™s FVM, Arweaveโ€™s Smartweave), but they have and will continue to be hard pressed to convince all compute and smart contract activity to migrate to their chains.

      • The ideal scenario would be to combine smart contract execution from e.g. a Substrate based Polkadot parachain such as Moonbeam or Astar with storage from a storage optimized chain like Arweave. If we look at NFT scenarios as an example, this is happening. The scenario is that you have an NFT contract on Mainnet, that has a pointer to a JPEG via an Arweave URL. The problem is that this is a one-way pointer between 2 independent systems. It is up to the application to mediate interactions between the 2 chains in the client. There is no awareness or connection between the contract and the JPEG other than the URL pointer in the contract. What if the contract could update access to and ownership of the actual data itself? What if the contract could read and act on the data stored? Simple functionality like this would open up a large number of new scenarios. End user UX could be substantially improved by removing the need for the user to understand and interact directly with both the contract and the storage blockchains, using potentially different accounts, keys, etc.

    • Vision

      • StorageHub is a storage optimized parachain that is designed to work with other Polkadot & Kusama parachains. It focuses on storing data in an efficient and decentralized way, while allowing that storage to be accessed, used, and managed by other parachains. It will be possible for users to directly interact with the storage on the chain, but StorageHub also seeks to natively interoperate with existing parachains via XCM.

    • Inspiration

      • Amazon S3

        • (https://en.wikipedia.org/wiki/Amazon_S3) was a key building block of web2 cloud infrastructure that greatly eased and improved data storage in web2 applications. With S3 devs could store arbitrarily large amounts of data in their apps without needing to get bogged down with storage infrastructure or scaling concerns. StorageHub seeks to do something similar for web3 devs building on Polkadot.

      • Filecoin

        • (https://filecoin.io/) is a storage optimized chain that creates a 2 sided marketplace of storage providers and storage consumers. The project is responsible for key innovations such as ipfs and libp2p, among other things. In many ways filecoin sets the standard for decentralized storage in the web3 space. Although the protocol seems focused on trying to compete with cloud and other centralized storage providers.

      • Arweave

        • (https://www.arweave.org/) is a storage optimized chain like filecoin, but that emphasizes permanent storage vs creating a time based storage marketplace. Users pay once to store data on arweave forever. It is popular to use for metadata associated with NFTs, among other things.

      • Project Greenfield

        • (https://github.com/bnb-chain/greenfield-whitepaper/blob/main/README.md) is a storage optimized chain designed to work with the BNB chain. It was born out of practical needs that the state of BNB chain is already many terabytes large and there is a need to offload unnecessary storage from the main BNB chain. There are lots of good cross chain ideas in Greenfield including having storage on Greenfield represented as NFTs on BNB chain which can be managed and whose ownership can be changed.

    Project Detailsโ€‹

    • Design and Implementation Principles

      • StorageHub will be a Substrate-native implementation deployed to both Kusama and Polkadot.
      • It will be a public good chain that uses DOT for fees, governance, and other utilities.
      • It will offer native XCM support such that parachains can interact with stored data and metadata in a trustless way..
      • End users and Dapps should be able to store and retrieve stored data from the chain.
      • The chain will create a 2 sided marketplace of storage providers and storage consumers.
      • A minimum of N copies of any given piece of data should be stored such that the system can survive the loss of some copies without losing the original dataset. Erasure encoding or similar technique could be optionally used to achieve this.
      • On the tradeoff spectrum between decentralization vs performance, we opt to always maintain good decentralization properties even if that means less performance is possible.
      • There will need to be a network of storage providers that supply storage to the blockchain.
      • The parachain will track metadata about the data being stored, and facilitate payments between the data owner and the storage provider.
      • A set of metadata associated with any stored data will be managed by StorageHub. This will allow the data owner to control access, and to transfer ownership of the data to other parties.
      • StorageHub doesnโ€™t aim to have smart contract functionality itself. Rather it strives to integrate, work with, and complement other smart contract or native parachains.
      • In creating the design for StorageHub, we will leverage previous research into polkadot and substrate based filestorage solutions such as:

    • Key Questions and Anticipated Challenges

      • Existing storage networks focus more on storage but less on user accessibility to that data. But storage without accessibility isnโ€™t that useful to users. Can we incorporate outside accessibility guarantees into the protocol?
      • What type of storage will it provide? Only immutable hash/value type or will it support mutable references (like a filesystem, useful to store/manage a web service or page)
      • What kind of XCM interaction (API) do we want to support?
        • XCM (mostly HRMP) costs may make some scenarios prohibitive.
        • Given the costs of XCM, to what degree does it make sense to store metadata on StorageHub vs on the controlling chain?
      • What do sustainable economics look like for storage providers, especially given that a public good chain wonโ€™t have a token to help bootstrap this side of the market?
      • How is data provided and stored without increasing PoV? This will most likely need to be a combination of offchain workers and a separate storage system. Regular substrate state canโ€™t be used for larger data storage, it would be used to keep tracking information about where and what data is stored.
      • What does this new data provider node look like and how does it work with other node types supporting the system?
      • How will the system ensure that enough copies of a given piece of data are present and available, given that storage provider nodes can go offline at any time.
      • How is it checked that data providers have the data they are being paid to store? What are the consequences of failing this check?
      • How do you manage censorship of data?
        • Different kinds of data that could be subject to take down requests. Data that e.g. a political party doesnโ€™t like. Data that is illegal in a given jurisdiction due to copyright or similar. Data that is both illegal and morally offensive.
        • Perhaps OpenGov tracks could be used for censorship takedowns.
        • Or data storage providers could be given censorship controls, and a permissionless staking design would make it so token holders could vote out providers that are out of line with community censorship standards.

    Ecosystem Fitโ€‹

    • Where and How Does StorageHub Fit In

      • There are currently no native Polkadot decentralized storage solutions and StorageHub aims to fill that gap.
      • Crust provides an incentive layer on top of existing storage protocols like ipfs. Whereas StorageHub seeks to be a storage provider itself.
      • StorageHub will be natively accessible by other parachains via XCM.

    • Target Audience

      • StorageHub is targeted for chains, contracts, teams and individuals that require data storage of larger datasets, and who value that storage being decentralized, censorship resistant, and permanent as long as storage fees are paid.
      • StorageHub will prioritize web3 developers that want to incorporate decentralized storage into their applications. This means a focus on APIs, SDKs, developer docs and education.
      • StorageHub will secondarily provide a reference application which allows users to directly interact with the system, storing data and managing data storage.

    • Use Cases

      • NFT, NFT marketplace, and Metaverse metadata storage
      • Dapps that require data storage
      • Personal and enterprise data storage - same as other storage chains.
      • DAO owned data assets - DAOs operating on existing parachains can manage access to and ownership of data assets on StorageHub.
      • โ€œTrueโ€ NFTs that can have the entirety of their associated data assets on-chain via a combination of an e.g. NFT contract and StorageHub stored assets.
      • Markets for data sets using NFT marketplaces.
      • New types of smart contracts that can act on StorageHub stored data on an one off or continuous basis

    Overviewโ€‹

    Stylograph [ stahy-luh-graf, -grahf ]

    A writing instrument for applying ink to paper.

    Stylograph is a framework aimed at enhancing the functionality of substrate-based chains in the Polkadot ecosystem with plugin-like functionality.

    By using the ink! programming language, third party developers can extend the core functionality, while focussing on the domain logic.

    The total ask for this proposal is $100,000 and it is planned to have a subsequent development to use this functionality within Genesis DAO (see the last grant, future plans section).

    Project Detailsโ€‹

    Introductionโ€‹

    A group of people surrounding Ken Thompson and Dennis Ritchie were quite busy at Bell Laboratories shaping the world as we know it today. They invented a milestone in programming languagesโ€Šโ€”โ€ŠC, the breakthrough operational system Unix, the first shell, UTF-8 and a long list of others that alone would have been enough to receive a Turing award.

    How were they so productive? Of course, the density of talent at Bell Labs was as high as within the Beatles (before John married)โ€Šโ€”โ€Šbut one tiny detail helped drive them. And that can be summed up in one word: focus. Finding out what holds the application together in its innermost folds and excelling at that. It takes writing programs that do one thing and do it well. Today, this set of guiding principles is popularly known as the Unix philosophy.

    This fundamental building block of system design is what guides Substrate development today. The Polkadot ecosystem is a set of domain-specific chains that focus on building the infrastructure for the web3 universe.

    The ink! programming language can be run on Substrate chains, either as a core value proposition - with the chain being an ecosystem for protocols developed in ink! on top of it - or as second class citizens - with protocols being able to build on top of the domain logic.

    Stylograph introduces a third use-case by utilizing ink! as a configuration language to alter the domain specific language itself by introducing a simple and straightforward framework to inject loosely-coupled hook points into your pallets that will call smart contract functionality in registered contracts on the contracts pallet.

    Motivationโ€‹

    Deep Ink Ventures is building a system parachain for the Polkadot ecosystem that is building infrastructure for Decentralized Autonomous Organizations - Genesis DAO.

    At Genesis DAO we are committed to the Unix philosophy.

    We focus on the DAO management with the core components of creating and running DAOs, overseeing token issuance and DAO treasury and having a rock-solid proposal and voting infrastructure.

    However, DAOs can have small and granular requirements that do require small tweaks and adjustments. Sometimes on-top protocols like Yield Aggregators require additional functionality. Some of those changes may be deal breaking for technical use cases or legal reasons and therefore a hard requirement for newly founded DAOs.

    The core team ultimately has to decide what features are reasonably part of an unbloated core and there is no one-size-fits-all solution to a lot of problems. This is where Stylograph comes to the rescue.

    Framework Components Overviewโ€‹

    The following is an overview of the architecture we build and is merely to sketch the scope and general concept. Implementation details may vary.

    pallet_stylographโ€‹

    This pallet acts as an abstraction layer on top of pallet_contracts in order to conveniently create callback based implementations.

    The pallet will have initial support for ink!. The concept is easily extendable for other languages such as Solidity or ask! that can be added.

    image

    Since Substrate does not know about the structure of smart contracts deployed in ink! beforehand, Substrate developers utilizing Stylograph need to register the function signature they want to support for callbacks.

    This is a one-liner in the chain specs:

    Stylograph is now aware of a function given by signature, function name or trait definition and knows its associated gas limit.

    image

    With the callback defined, the core developers now can add callback functions into their pallets that extension developers can utilize.

    For example, the function above may alter the original vote in order to come up with a more complex algorithm (and it is therefore valuable to carefully select the arguments for the callback function for extension developers to be flexible).

    An example might be something like this:

    image

    The next part is the registration of extensions by accounts - the second argument given in the callback above.

    The Substrate node implementation can decide how they want to interpret this - e.g. if the extensions are per account or if the account represents an entity on the chain. The latter is true for Genesis DAO where the account needs to be the owner of the DAO. Each DAO can register its own hookpoints to tweak the core to its needs.

    image

    The framework now has all the information at hand to execute a fully abstracted _pallet_contracts::bare_call _and to handle errors associated with it:

    1. The user calls the extrinsic of the implementing pallet. In the case of GenesisDAO that might be the dao_votes pallet to intercept the voting process in order to alter the majority voting to a different decision system.
    2. This pallet executes the callback that takes the information given from the dao_votes panel and looks up the callback definitions registers.
    3. It constructs a call to the ink! contract defined.

    image

    The gas fees are therefore called by the person utilizing the functionality - the user calling the initial extrinsic.

    ink! Stylograph Facade Builderโ€‹

    The aforementioned information is enough to automagically generate a full boilerplate contract as template that Substrate chain developers can use to deploy a sample contract and to write a macro that defines the interface that the runtime expects.

    This contract can be released to the extension developer community to use as a boilerplate template. They can as well import the trait for the contract to be sure that they are compatible with the specs defined by the runtime.

    image

    We therefore are building a CLI tool to package a versioned ink! crate with installation steps and base documentation that can be published with a new runtime release of the chain to give protocol and extension developers a headstart to extension development. Both the chain and the contract will depend on those traits as dependency to identify the interface.

    image

    Additional Developmentโ€‹

    As this is planned to be part of our to-be-planned-system-parachain, we are as well pushing the development of the main chain within this proposal.

    Token Transferโ€‹

    Currently we rely on wallet extensions and polkadot.js.org to transfer DAO tokens around that reside on Genesis DAO. We have a primitive frontend UI in our MVP but would like to expand this to a more user friendly interface.

    We have already created some designs to show the direction, but this would include full wireframes, designs + additions to our backend services and, of course, the dApp:

    image

    Council Managementโ€‹

    Weโ€™ve already created the multisignature part of council and treasury management within our product / wireframe and design department and want to roll out a Gnosis Safe - Style interface for this as part of the treasury management.

    We are using pallet_multisig for this and currently council members need to go via polkadot.js.org, not the most user friendly interface in the world.

    This would again include the full wireframes, desings and code changes in the backend and frontend. We have already implemented the multisig part.

    image

    DAO Dashboard Add-Onโ€‹

    We are createing a few designs to make the DAO Dashboard more friendly and intuitive for users and want to do the frontend implementation as well as the respective adjustments to the APIs of our backend service.

    image

    Ecosystem Fitโ€‹

    While we have drafted this pallet with the next iteration of the Genesis DAO chain in mind (here are some planned plugins and extensions for inspiration), the presented functionality is carefully abstracted into a reusable component system.

    Stylograph is to Substrate what plugins and and extensions were for CMS, Shops in web2 - a smooth way for third parties to extend the core functionality for a chain. It enables Substrate developers to concentrate on doing their domain logic well whilst their users and protocols building on top maximize flexibility and time-to-market.

    You can think of this as the inverse to chain extension. While chain extension gives plugins a way to interact with the underlying core logic, stylograph gives chain developers an easy framework to make their core extendable with plugins and extensions via smart contracts. They can be used by any chain that wants to have a growing extension ecosystem.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Introductionโ€‹

    SubDAO is a Cross-chain Platform built by SubDAO Labs to link DAO and DApp on Polkadot. It will be the infrastructure to maintain DAO and to connect DApp with DAO in the world of Web3.0 powered by Substrate and Polkadot.

    The SubDAO will run as a parachain to provide specific services. The various DAO templates and SubDAO Airfone will alleviate the burden on developers to maintain DAOs and to create very DApps linked with DAOs.

    The initial governors of a DAO can easily create a cross-chain DAO by only a few clicks without any tech skills at all. Developers who are willing to build DApps can give the governance to communities by using SubDAO to create the very DAO connected to DApp through SubDAO Airfone.

    Integrationโ€‹

    SubDAO is a customized chain based on the Substrate 2.0 Framework and will run as a parachain on Polkadot. The OCW (Off-chain Worker) provides the ability to access the off-chain world, which would empower the DAOs to access external data rather than only On-chain data, such as the price of stable coins, the contributions on Github, and so on.

    Team Interestโ€‹

    The initial members of the SubDAO Labs team are big fans of Web3.0 technology. They come from different areas, ranging from full-stack developer, product manager, project management to cryptocurrency early adopters. DAO is the ideal governance model in the mind of the team. Creating and maintain a DAO is not so easy, especially to make a DAO working across different chains. But with the help of Substrate 2.0 and Polkadot, the team thinks it is the time now.

    Creating a DAO is not a new thing to the guys involved in the blockchain world, just like shooting a man to the Moon is not news to the fiction novel readers nor people. But the opportunity for everyone to easily travel forth and back between the Moon and the earth is making a big difference! All the team trying to do is to build a cheap, reliable, and fast enough vessel for people to travel between the Moon and the earth even further between Mars and the Earth. The team wants to provide a cheap, reliable, and fast enough way to let everyone being able to create DAOs and DApps across different chains.

    Project Detailsโ€‹

    Architectureโ€‹

    With the state-of-art technology, SubDAO Labs can achieve the goal based on Substrate 2.0 and the Polkadot. The SubDAO project contains SubDAO node, Template Library, SubDAO Guard, Asset Vault, SubDAO Airfone, and Front End.

    img

    • SubDAO Node is the customized chain node for the SubDAO network built by Substrate 2.0. It's the fundament of the SubDAO network that contains the basic functionalities as a normal chain node but also provides the ability to fetch external data needed for DAO governance with the OCW (Off-chain Worker) from Substrate 2.0 Framework.

    • Template Library is the key component of the SubDAO network. It is comprised of multiple contracts. The main functionalities of Template Library are managing and providing various DAO Templates for different types of organizations. Everyone has the right to define new DAO Templates according to their needs, and the SubDAO network provides some default DAO Templates such as Voting Template, Fund Template, VC (Venture Capital) Template and so on.

    • SubDAO Guard is the original DAO of the SubDAO network. It provides basic management functionalities. Every member of the SubDAO network can get involved in the SubDAO network governance through SubDAO Guard.

    • Asset Vault is the smart contract providing the basic features of manage assets for each DAO. Working together with DAO Template, the Asset Vault manages all kinds of assets, including the assets needed by creating a new DAO, the assets deposited by the governors of a DAO, and other assets.

    • SubDAO Airfone is the SDK for developers to connect their DApps with the DAOs created by themselves or others. It will be provided as a Javascript library at the beginning, and in other languages later. Developers can use the SubDAO Airfone to interact with the SubDAO network directly or built their DApps with the connection to DAO.

    • Front End provides Web UI for everyone to interact with the SubDAO network. All the users need to do is open the webpage deployed by the SubDAO Labs team or by users themselves and click the buttons following the manual. Front End will provide such functionalities as creating a new DAO, define a new DAO template, withdraw personal assets, voting in DAO, and so on. Front End will be built with NodeJS.

    • SubDAO Token $SDT is the native token of the SubDAO Network, and it will play the role of governance and other utilities. $SDT is necessary to secure and power the SubDAO Network. The SubDAO Network may hold an IPO and reward community members for helping our auction with $SDT tokens during the Parachain Auction.

    Scenariosโ€‹

    • Scenario to Create a New DAO
      img

    As shown above, the steps to create a new DAO are marked. The DAO governor calls the smart contract of the SubDAO Guard to choose a proper DAO template from the DAO Template Library. After the governor fills the basic information required by template such as name, description, the rules of governance, initial members, and so on and deposits the initial fund to the Asset Vault, the SubDAO Guard contract will create the very DAO according to the chosen template and filled information. All extra information, such as images, texts, and files, will be stored in a decentralized storage network like IPFS.

    • Scenario to Attend a New DAO
      img

    Generally speaking, there are two kinds of ways to interact with DAO contracts. The first way to get involved with a specific DAO is using the Front End created by the SubDAO Labs to interact with all the DAOs on the SubDAO Network. The second way is using the SubDAO Airfone. The SubDAO Airfone will hide all the details of calling smart contracts for users and is used by DApps since the developers of DApps can customize their scenario according to their needs.

    The Open SDKโ€‹

    Our ultimate goal is to provide an essential open SDK (the SubDAO Airfone) from a high-level perspective together with the above components, fully powering the ecosystem of DAO across chains on Polkadot. With the functionality of the Open SDK, anyone involved can utilize DAO and DApp.

    The benefits of an open SDK are beyond criticism. The Open SDK will be an extension of both the DAO's capabilities and the value of the DApps through the whole Polkadot universe. We hope to build a framework whereby any Decentralized Autonomous Organizations can live, and any Decentralized Apps can use in the Polkadot ecosystem.

    Substrate / Polkadot Integrationโ€‹

    The whole SubDAO Network builds on top of the Substate 2.0, and the Polkadot ecosystem is essential to what SubDAO Network is trying to achieve. The SubDAO Network will be connected to the Polkadot ecosystem as a parachain, sharing the Polkadot underlying consensus, and protected by the network performance of Polkadot and Substrate.

    The off-chain worker is a new feature in the Substrate Framework that allows the SubDAO Network to interact with off-chain data.

    The node in the SubDAO Network is built with OCW (Off-chain Worker) enabled. The figure below shows how it will work with external data (for example, the contributions on Github).

    img

    In the figure above, the SubDAO Node includes an OCW pallet that interacts with external HTTP service (Github Http Wrapper). Since the OCW pallet is a general component, most of the processing work of external data is moved out of OCW to decrease the complexity of implementation and give the ability to the DAO governors who wanna use specific data sources for their DAO. The external HTTP service (Github Http Wrapper) will fetch the data such as contributions for a user in a project or repository from Github.com and feed the OCW pallet in the SubDAO Node.

    All smart contracts mentioned above will be implemented with Ink or EVM. Since the SubDAO Node includes OCW (Off-chain Worker), Ink is essential due to Ink is the only way to interact with pallets currently. Thanks to Ethereum, Solidity is widely used over several years, and most of the developers are already familiar with EVM. So in the SubDAO Network, most of the smart contracts will be implemented using EVM to decrease the difficulties for new developers on the Polkadot ecosystem.

    img

    As shown above, those contracts interacting with pallets will be implemented with Ink, and others will be with EVM. Later in future versions, when developers get familiar with Ink, the whole project will upgrade to use Ink only.

    For EVM, we will choose Frontier as the evm pallet.

    The Pallet Implementationโ€‹

    The function provided by the pallet to get off-chain data is requestOffchainData.

    1. requestOffchainData

    • desc: smart contract requests the off-chain data, the SubDAO network nodes will send data to the SubDAO chain through OCW integrated later.
    • params: HTTP wrapper URL, JSON params
    • return: dataId

    Ecosystem Fitsโ€‹

    In the area of Decentralized Autonomous Organizations, there are many mature DAOs maintained in different ways with different tools or platforms, such as Maker, The DAO, and The LAO. Also, there are some other tools to help governors building a DAO, such as Aragon. Aragon is a project providing tools to create and the governor a DAO, but only available on Ethereum.

    SubDAO is quite different and evolved from other DAO related projects. The goal of SubDAO is to create a (1) cross-chain platform providing (2) general and customized functionalities to govern a DAO (3) connecting to DApp with the ability to (4) access off-chain external data.

    The project meets the need of signing contract with decentralization, immutability, and transparency. It provides the way for DAOs to sign contracts with DAO members and contributors.

  • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    To sign a contract with the help of blockchain technologies is not fresh. There are similar projects in the Ethereum ecosystem, such as OpenLaw, EthSign. But there is no similar project in the Polkadot ecosystem yet. PolkaSign is the first one to provide electronic agreement signing for individuals, companies, and DAOs.

    Users have to choose a pair of token and passphrase, which we recommend having a common token(more than 16 chars) in every provider that they subscribe but have a different passphrase(can be small). Users will submit sha256(token+passphrase) to the contract, and whenever they want to authenticate themselves, they have to provide these token and passphrase in a view function( which is not a transaction, so it's not on-chain and free). They also have to once set their sha256(token+passphrase) for using the SubsCrypt dashboard without a wallet. The authentication with a wallet is checked by the blockchain address sender.

    First milestone: we will design(it is almost done right now) and implement our smart contract, and we will also design XD files of UI, and we will write our white-paper in this milestone(including the test unit).

    The main functions that will be deployed on the chain in this milestone are as follow:

    Project Detailsโ€‹

    Runtime APIsโ€‹

    Subsembly must implement the following Runtime APIs to have full support for GRANDPA:

    Runtime-to-Consensus Engine Messagesโ€‹

    GRANDPA utilises consensus digest items for various events. The following is a list of the digest items emitted related to GRANDPA: Untitled (20)

    Scheduled Change & Forced Change

    Every pallet/module has an on_finalize hook that is called whenever a block is finalised. In the case of GRANDPA, once the on_finalize is called, the Runtime must check whether there is a PendingChange (forced or scheduled) that must be deposited. If there is - a new DigestItem of type Consensus with the GRANDPA_ENGINE_ID must be added in the block.

    On Disabled

    The ConsensusLog is deposited once the Session module calls the on_disabled method. The GRANDPA module must simply deposit the log whenever it is called from the Session module.

    Public Functionsโ€‹

    The following public functions, eligible for calling from the client side are:

    Dependencies & Prerequisitesโ€‹

    It is important to note that GRANDPA relies on the Session, Offence and minimal Staking modules. The Session module is configured to have a certain range of blocks and every time on_initialize is called, the module checks whether the session should end. If it has to end, the module rotates the session changing the validators.

    The offences module tracks reported offences and the Staking module must provide the implementation of the offence - slashing the users for their misbehaviour.

    Ecosystem Fitโ€‹

    Subsembly provides an alternative way for developers to build Runtimes. More specifically, it enables developers with TypeScript/JavaScript knowledge to build on top of the Substrate ecosystem.

    The team already spend time on implementing GRANDPA, by updating the Subsembly CLI and spec builder to support GRANDPA authorities configuration. Reference

    Development Roadmap ๐Ÿ”ฉโ€‹

    Described below is a practical approach to the implementation of the GRANDPA module along with the the other auxiliary modules that are required.

    1. Session
      1. Implement session period configuration (n number of blocks)
      2. Implement an on_initialize hook called when the block is initialized. It must check whether the session must end; if it ends, rotate_session is called.
      3. Implement a service for tracking the Historical changes of session keys in order to verify proofs
      4. Implement rotate_session
    2. GRANDPA - Session
      1. Implement on_new_session handler
      2. Implement schedule_change
      3. Implement on_finalize hook
        1. Pending changes added in the state from schedule_change must be deposited as logs.
    3. Session
      1. Implement set_keys method. The extrinsic must be signed. The caller gets their provided keys set into storage for eventual usage in the next sessions
      2. Implement purge_keys method. Removes the session keys of the function caller. Takes effect after the next session starts
    4. GRANDPA - Consensus Messages
      1. Add on_finalize hook - If the current block is X, pending scheduled authority changes for the same block must be executed and an event must be deposited

    At this point, the following features should be supported by the module:

    The last part is to add support for equivocations.

    1. Equivocations - Reporting voter misbehaviour. The reporting of equivocations results in offences and slashe
      1. Implement a service for verifying the equivocation_proofs - verifying the offender keys against the proof
      2. Implement a method for verifying the equivocation proof by making sure that both votes target different blocks and the signatures are valid
      3. Implement Reporting Service for offences that reward the sender
      4. Implement Offences module that tracks offences
      5. Implement minimal Staking module that provides an implementation for slashing on_offence as OffenceHandler

    Substrate Move System Pallet (part 1)

    • Team Name: Eiger
    • Payment Address: Fiat 14.04.2023, 16:50 UTC+3
    • Level: 3

    Project Overview **๐Ÿ“„**โ€‹

    This application is a response to the Move Smart Contract Pallet RFP.

    Overviewโ€‹

    Some terminology first:

    • Substrate Move System Pallet - A Substrate system pallet that can be used as a building block for substrate-based chains, it exposes interfaces to interact with the Move virtual machine.

    • Substrate Move - A Move language fork that is Substrate compatible.

    Objectives:

    • The goal is to provide a Substrate system pallet that allows to deploy and interact with Smart Contracts written in the Move language, by providing a Move Virtual Machine (MoveVM) as a pallet.
    • We plan on exploring a fork of the Move language, so itโ€™s adjusted to work with the Substrate ecosystem, as well as developing a Substrate system pallet that allows the execution of Move smart contracts.
    • The project directly improves the growth potential of the Substrate based ecosystem by providing support for one of the most modern smart contract programming languages and VM types out there - Move.
    • We are interested in creating this project because we are firm believers in the modular vision of web3, and only by collaborative efforts on improving and unifying the technology between different chains and the languages, will we get better products as an outcome.

    Goal - Level up the growth possibilities of the Substrate ecosystem by providing a way to develop and execute Move smart contracts on Substrate.

    This is the first phase of a 3-phase development program:

    1. In-Depth Exploration and Assessment of MoveVM and Substrate Integration
    2. MoveVM compatibility work and Subtrate Pallet development
    3. Finalising the Substrate-Compatible MoveVM

    Project Detailsโ€‹

    Prior work

    We are basing the core architecture and many of the design decisions on the Pontem networks developed system pallet for Move VM. They had maintained their own fork of the Diems Move language, which was used as the base execution layer for their version. Both of these repositories have not been maintained for a very long time already.

    โ™ป๏ธ We aren't seeking to maintain any of the existing codebase; rather, we aim for a full revival through a new greenfield project. Our rationale for this stems from the substantial advancements made in the Rust, Substrate, and Move ecosystems since Pontemโ€™s latest commits from over a year ago. We believe that handling potential code rot due to the passage of time might be more labor-intensive than starting afresh and drawing upon existing projects for more current guidelines.

    Documentation of core components, architecture

    1. Substrate Move:

      The first part of the project will be a MoveVM fork, as some major changes will need to be made to the codebase for it to be substrate compatible. For example:

      • no_std compatibility: Making it lightweight and suitable for use in Substrate runtimes.
      • wasm32ย target compatibility: Adapting all the VMโ€™s different components to work efficiently and securely on the wasm32 target architecture.

      We plan on creating and maintaining the fork in a manner that would allow us and the community to easily follow and track changes from the upstream, thus making the maintenance and change tracking to be much simpler.

      At the time of writing this application, we suspect that this will be needed because this is what also Pontem had to do to support it in their version. This will be further researched and assessed during the first milestone.

    2. Move VM system pallet:

      The second part of the project will be a Substrate virtual machine pallet in Substrate. This is a modular component that is needed to integrate a specific new VM into a Substrate runtime. It will serve as a bridge between the runtime and the Move VM, managing resources and translating data or actions between the two environments.

    API specifications

    As a minimum, we plan on providing all of the RPC calls that the Pontem crate did. As the team progresses with the implementation, we might add or remove RPC calls as we best see fit.

    Move language has a concept of โ€œgasโ€ for executing contracts, whereas Polkadot uses โ€œWeightsโ€. Each Move transaction invocation requires providing a gas limit for execution, and itโ€™s necessary to be able to transform the values between weight and gas:

    • mvm_gasToWeight
    • mvm_weightToGas

    Estimating gas for different operations:

    • mvm_estimateGasPublish
    • mvm_estimateGasExecute

    Working with the primitives of the Move language:

    • mvm_getResource
    • mvm_getModuleABI
    • mvm_getModule

    Tech stack

    We plan on using Rust for developing the system pallets and using existing Move language smart contracts for end-to-end testing of the whole workflow.

    Notes

    Because the Move language requires a fork to work with Substrate chains, and modifications to the address size, there might be incompatibilities with deploying existing Move Smart Contracts from other chains that make use of the address properties size, as well as the compiled ABI and bytecode for those contracts might be invalid. To deploy on our MoveVM system pallet, the forked toolchain must be used to re-compile all smart contracts. The address size of Move language is configurable via a feature switch with 32-bits being one of the options.

    Ecosystem Fitโ€‹

    Move is a smart contract programming language that emphasizes access control and scarcity, offering some unique advantages over other popular VMs in blockchain ecosystems.

    The importance of bringing the MoveVM to Polkadot was recognized over two years ago when Pontem Networkย started working on aย Move virtual machine palletย to execute Move smart contracts on Substrate-based chains. Although they discontinued the project and haven't updated the codebase for over a year, the W3F still keeps this RFP, which serves as evidence that porting the MoveVM is crucial for the future of the Polkadot network.

    We concur with this perspective and have actually been actively researching the MoveVM - exactly with a similar idea of helping port it over to other chains.

    1.System Pallet: Substrate MoveWe will create a Substrate system pallet that will provide the RPC calls as the initial interfaces for interacting with the Move VM. The Move VM port itself will not be implemented, all of the methods will be empty stubs.
    Solid code practices will be in place: CI/CD, tests, documentation, linting, and publication of the library to http://crates.io.

    3.Rust crate: Substrate Move documentationDocumentation of the alteration made for the MoveVM to be Substrate-compatible. Also, the whole process of how it was ported will be described, either in form of markdown documentation or detailed commenting on GitHub issues and PRs.

    Future Plansโ€‹

    This is the first phase of a 3 steps development plan:

    1. In-Depth Exploration and Assessment of MoveVM and Substrate Integration
    2. MoveVM compatibility work and Subtrate Pallet development
    3. Finalising the Substrate-Compatible MoveVM

    The next step will be to submit a grant proposal to continue this work - creating the first iteration of a pallet capable of receiving, storing and executing Move smart contracts.

    We hope that upon the completion of all phases of creating the Substrate Move System Pallet , it will open doors for further collaboration and community input on the project. We strive to have the codebase well documented so that others might join in and contribute.

    While there are no long-term plans set in stone for the usage of this pallet, we have had incredibly exciting discussions about creating a parachain, possibly a common good parachain (system parachain), that utilizes this MoveVM implementation and would run MoveVM contracts. As we near the completion of this initial development, we will be discussing these future plans more in-depth.

    How did you hear about the Grants Program?

    We learned about it when looking at open RFPs by the web3 foundation on their website.

    We wanted to get back up to date on what is happening in the Polkadot ecosystem, and working on grants, specifically RFPs, has been a great way to do so.

    Looking to apply to other RFPs currently open as well. Stay tuned!

    We concur with this perspective and have actually been actively researching the MoveVM - exactly with a similar idea of helping port it over to other chains.

    Milestone 1 - MoveVM compatibility work and Subtrate Pallet developmentโ€‹

    • Estimated Duration: 2 months
    • FTE: 2
    • Costs: 96 000 USD

    Goal: Create a customised Move VM solution for the Substrate ecosystem, using the knowledge gained during the first milestone. The deliverable will be a pallet capable of receiving, storing and executing Move smart contracts.

    NumberDeliverableSpecification
    0a.LicenseApache 2.0 and MIT
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Rust crate: Substrate MoveForking the Move VM, as deemed necessary from the research done during the first milestone. The alterations will include everything to create the virtual machine Substrate-compatible. We will also provide extensive documentation of how the whole process is designed and how it is to be maintained.
    2.System Pallet: Substrate Move SP adds Move functionalityIntegrating the Move VM runtime within the custom pallet, ensuring compatibility with the Substrate blockchain and Move smart contract execution.
    3.System Pallet: Substrate Move SP APIs to interact with the Move VMDeveloping an API that enables developers to interact with the Move VM on Substrate-based chains, allowing them to deploy, execute, and manage Move smart contracts.

    Future Plansโ€‹

    This is the second phase of a 3-phase development program:

    1. In-Depth Exploration and Assessment of MoveVM and Substrate Integration
    2. MoveVM compatibility work and Subtrate Pallet development
    3. Finalising the Substrate-Compatible MoveVM

    The next step will be to submit a grant proposal to finalize this work - finishing up the pallet and making sure it works properly and can be utilized by other developers .

    We hope that upon the completion of all phases of creating the Substrate Move System Pallet, it will open doors for further collaboration and community input on the project. We strive to have the codebase well documented so that others might join in and contribute.

    While there are no long-term plans set in stone for the usage of this pallet, we have had discussions about possibly creating a parachain, possibly a common good parachain, that utilizes this MoveVM implementation and would run MoveVM contracts. As we near the completion of this initial development, we will be discussing these future plans more in-depth..

    How did you hear about the Grants Program?

    We learned about it when looking at open RFPs by the web3 foundation on their website.

    We wanted to get back up to date on what is happening in the Polkadot ecosystem, and working on grants, specifically RFPs, has been a great way to do so.

    Looking to apply to other RFPs currently open as well. Stay tuned!

    Future Plansโ€‹

    Upon completion of the journal article, the team will look to apply for a grant from the Treasury to promote the article in-person at academic conferences and at universities. After the dissemination of the foundational case study for soulbound tokens and the Social Recovery pallet at institutions and university blockchain clubs globally, we have plans to conduct follow-up research with law students and academic researchers in the field of Law on the potential legal impacts of soulbound tokens on estate law. As Justin Goldston is an Graduate Advisory Board Member at Georgetown University, Law Professors at Georgetown are curious about the impact of NFTs within the legal practice. Additionally, after a presentation for faculty members from the Smeal College of Business and the Dickinson School of Law at Penn State University, which can be seen here https://bit.ly/3AQiH0C on sustainable impacts of the metaverse, Professors from the Dickinson School of Law are also looking to conduct research on NFTs, the metaverse, and law. After the completion and publishing of the original article, the team looks to conduct a follow-up study of the legal impacts of soulbound tokens. Next, we also look to continue to work with the team at Phala to build out a proof of concept with Intentionally Designed Solutions for the Kusama ecosystem with hope that this concept could be moved to Polkadot once the Social Recovery pallet is available on Polkadot. To continue the awareness of the Social Recovery pallet and the proposed digital inheritance tool, we mentioned the concept to Ray Lu - the Founder of Bit.Country - and we hope to introduce this tool within the Bit.Country metaverse within the Polkadot and Kusama ecosystems. Finally, with the recent annoucement that the Klaytn blockchain has developed a strategic partnership with Parity, in an effort to demonstrate the interoperability of Substrate, we will also work with Neo Yiu and Dr. Sangmin Seo on integrating the proposed solution into the Klaytn metaverse.

The reason behind this is the ease of implementation, and the availability of various libraries and technologies that can be added on top of it. This service won't receive many calls, rather act as a relayer that reads data on-chain, and then submits data/send calls to Smart Contracts on-chain, without further need for external calls. As a core tool for creating calls to Smart Contracts, we will leverage Polkadot.js Contracts API.
  • SDK JavaScript and TypeScript will be fundamental programming languages of this part, while NPM registry will be used for publishing the package itself. The SDK will be basically a wrapper of the certain functions that call Smart Contracts, and Backend. It will require the developer to add configuration, such as API Key to access our backend, Smart Contract Factory address, as well as the ABI files, that will serve as an instruction for calling each Smart Contract. We are not going to hardcode those in the SDK, as in the future, the platform may be deployed on different chains in the Polkadot ecosystem. Moreover, the Smart Contracts can be upgraded, or created with different set of rules and methods.
  • SDK Documentation The entire documentation for implementing SDK in the given project, will be built using Docusaurus that leverages JavaScript and TypeScript.

    Project Overview ๐Ÿ“„โ€‹

    This application is in response to the RFP Data Analysis Tools for Substrate-based Blockchains

    Overviewโ€‹

    TPScore simplifies TPS Data Analysis for non-technical users in the Polkadot Ecosystem.

    TPScore aims to provide non-technical users in the Polkadot ecosystem with an accessible and user-friendly platform for analyzing TPS (Transactions per Second) data. Our goal is to bridge the gap between technical intricacies and user-friendly visualization, empowering individuals to make informed decisions about blockchain adoption, investment, and development.

    Adoption levels and community engagement are vital indicators of a blockchain's success. They directly impact the attractiveness of a network and its potential for growth. While social media followers, media coverage, and developer activity are commonly considered metrics, the true measure of adoption lies in TPS. TPS is a robust metric that correlates with the economic activity on a blockchain, making it a crucial parameter for understanding and evaluating different chains.

    When users choose a blockchain for investment or development purposes, conducting a thorough analysis of each chain is essential. Polkadot's unique architecture and scalability prospects, with its interconnected parachains, offer a vast ecosystem of possibilities. However, determining the TPS of Polkadot and its 40+ parachains is currently a complex task that requires technical knowledge and data analytics expertise. This creates a significant barrier for non-technical users and even presents challenges for those with technical know-how, as gathering TPS data for multiple parachains can be time-consuming.

    TPScore aims to simplify the process of TPS analysis by providing an intuitive and user-friendly analytics website. We remove the need for users to perform complex ETL (Extract, Transform, Load) work or possess specialized data analytics skills. Our platform presents TPS numbers for the Polkadot Relay chain and parachains in a readily understandable format, accessible to anyone. We empower individuals to effortlessly access and compare TPS data across different parachains, enabling them to make informed decisions regarding investments, project selection, and engagement within the Polkadot ecosystem.

    Project Detailsโ€‹

    The final state of the project will consist of two key components:

    1. ETL System: This component will be responsible for fetching data from the blockchain, transforming it, and storing it in a relational database.

    2. User Interface (UI) with data visualizations: The UI will provide a user-friendly interface to access and analyze TPS data. It will include visually appealing and informative visualizations of the data, reducing users barier to understanding blockchain metrics.

    The initial version of TPScore, which will serve as a POC, will cover the Relay chain and 38 parachains. The UI interface will be designed to be accessible on both desktop and mobile devices, ensuring a seamless user experience across various platforms.

    To fetch blockchain data, we will leverage two methods:

    1. Subscan API (list of parachains accessed with Subscan API)
    2. Public endpoints (list of parachains accessed by public endpoints)

    1. ETL Systemโ€‹

    We will retrieve blockchain data using either the Subscan API or connect to the public endpoints of parachains using the Substrate interface library.

    To ensure streamlined and efficient data processing, we will leverage Apache Airflow.

    To calculate the average TPS, we will take the number of transactions within the last 100 blocks. We will fetch raw data at regular intervals of every 10 minutes. This raw data will then undergo processing within Airflow's DAGs using Python Operators, ensuring efficient data transformation and preparation.

    Finally, the processed data will be stored in a MySQL database to be later picked up by Next.js framework.

    2. User Interface (UI) with data visualizationsโ€‹

    We will use Next.js as our full-stack framework. It allows us to both retrieve data from MySQL database and render React app on a server.

    To visualize data, we will use a simple and concise UI: the grid of cards with the blockchain's name and TPS. We expect one common use case: users go to our website and scan through all chains to find a desired one. So we will simplify this process by adding handy sorting and filtering.

    Out of scope detailsโ€‹

    During this stage, our focus will be solely on the Polkadot ecosystem, and we won't be providing coverage for the Kusama ecosystem. This decision allows us to concentrate on testing the market fit of our Proof of Concept (POC) within the Polkadot network.

    Additionally, we will exclude a specific set of parachains from our analysis (out of scope parachains). These parachains are either not yet live on the mainnet or lack a public endpoint for data access.

    Ecosystem Fitโ€‹

    Our project addresses a critical gap within the Polkadot ecosystem by providing comprehensive data visualization and analysis tool. Currently, obtaining data from Substrate-based blockchains relies on block explorers that offer a limited set of metrics or require technical skills to access and transform raw data from parachain endpoints. Recognizing this challenge, we aim to simplify the life of Polkadot ecosystem users with easy access to sophisticated network metrics for analyzing network parameters and comparing blockchains.

    Our target audience comprises advanced blockchain users who seek convenient access to comprehensive network metrics but lack the technical expertise or time to perform complex analyses independently. We understand their need for intuitive tools that enable efficient evaluation of blockchain networks, helping them to make informed decisions.

    As of the time of this application, no tools exist for checking TPS across the Polkadot Relay chain and parachains. However, there are 2 similar projects, ETHTPS and RealTPS, which focus on the Ethereum and other layer-1 networks. The presence of these projects indicates the existence of user needs and market fit. Unfortunately, both of these projects do not cover Polkadot ecosystem and fall short in terms of user-friendliness, highlighting the need for improvement in its UI design.

    Development Status ๐Ÿ“–โ€‹

    This project is a response to RFP Data Analysis Tools for Substrate-based Blockchains

    Up until now, our primary focus has revolved around two key objectives:

    1. Finding product-market fit
    2. Ensuring credible API/endpoints availability for the Polkadot ecosystem

    1. Finding product-market fitโ€‹

    Max TPS has long been a core indicator of blockchain performance and speed. Numerous articles and blogs compare the maximum TPS of different networks, highlighting its significance (Article 1, Article 2, Article 3, etc.). However, max TPS is often based on theoretical calculations rather than real network utilization, making real-time TPS measurement a more valuable alternative. Notably, projects like ETHTPS and RealTPS already track TPS outside the Polkadot ecosystem, indicating a growing interest in real-time TPS tracking.

    2. Ensuring credible API/endpoints availability for the Polkadot ecosystemโ€‹

    We have successfully identified methods to retrieve data from the Polkadot Relay chain and 38 parachains. We will utilize the Subscan API or connect to the public endpoints of parachains using the Substrate interface library. It is important to note that locating functional parachain endpoints may be challenging for average blockchain users, as there is no centralized source providing all parachain endpoints. Moreover, certain parachains lack public endpoints and will be excluded from this POC. However, we may consider including them in future versions by directly engaging with the respective parachain teams.

    For a detailed list of the parachains accessed through the Subscan API, parachain endpoints, and the out-of-scope parachains, please refer to the provided link

    Our primary goal for this project is to develop a POC and validate our assumptions regarding its market fit and appeal to Polkadot users. If we receive a positive response from the community, we intend to dedicate more time and resources to further develop the project.

    In future versions, we have identified several potential features to consider:

    1. Including support for Polkadot parachains that are currently out of scope for the POC by directly engaging with the respective parachain teams.
    2. Incorporating historical data and visualizations to observe the TPS dynamics of specific parachains or the relay chain over time.
    3. Expanding the project to include data from the Kusama Relay chain and its associated parachains.
    4. Enabling easy comparisons by incorporating data from other non-Substrate-based blockchains.
    5. Extending the project beyond TPS tracking to include other valuable parachain-related data that is typically challenging to retrieve without technical expertise.

    How did you hear about the Grants Program?

    We learned about it via Web3 Foundation Website. We've been closely monitoring the DotSama ecosystem for more than a year, we've read documentation, tested various projects/parachains, and participated in staking. After getting a deeper understanding of the technology and the ecosystem we decided to test our own idea and build a POC of a data analytics website for the Polkadot ecosystem.

    This application is a logical next step in our continued interest in Substrate-based chains and Polkadot in particular.

    2. A demo block index engine (GitHub Repo);
    3. A WASM library for the demo of dTRE technology (GitHub Repo);
    4. A demo app to use the dTRE technology as a Chrome extension (GitHub Repo);

    The demo mentioned above is deployed on AWS and may be accessed with a web link. It is worth noting that Our final release will use a different type of technology based on hardware encryption.

    In the current stage of TREX development, we are working on the following software with the Rust programming language to deliver public test-net and main-net:

    1. TREX node software that supports fundamental blockchain functionalities, consensus, and keyholding;
    2. The customized TREX archive software scans the blockchain and unlocks encrypted data, and releases it according to its preset clock (GitHub repo);
    3. The TREX API library to submit dTRE data as a form of Substrate extrinsic to TREX nodes (GitHub repo);
    4. The infra-as-code (IaC) TerraForm script to deploy the TREX test-net and backend services (GitHub repo);

    Since we are working on a new version of TREX node software using confidential computing technology, we need to rewrite our consensus code and design the off-chain worker code for keyholding. The first version of the demonstration of dTRE will be built as a side-chain in an existing decentralized network since it has tested its implementation using off-chain workers within the TEE. However, we will have to develop some specific pallets to support our tokenomics. Thus, our network cannot be a side chain in its final formation. Unlike other networks using confidential computing technology, we are not supporting general computing in TEEs but focus on dTRE technology built on top of confidential computing hardware.

    We are not working on a universal public chain like ETH or Polkadot that serves as layer-0 infra. Our parachain only focuses on providing a specific decentralized infra service - the decentralized timed-release encryption for cross-chain applications.

    We are not building a smart contract platform but provide APIs to any cross-chain smart contracts if using dTRE technology.

    We are not going to build a web or mobile application for end-users (e. g. decentralized strategy markets), but we are working with our business partners by providing them dTRE infra services and integration toolchains. Moreover, we are trying to attract more third-party developers to our network and the Polkadot ecosystem to develop various dApps based on the dTRE technology and Polkadot cross-chain technology.

    We are not providing infrastructure for general confidential computing but only focus on dTRE technology with confidential computing hardware.

    Ecosystem Fitโ€‹

    Our final goal is to create a new frontier of dAPPs with dTRE technology in the Web3 domain. The Polkadot ecosystem provides very comprehensive and advanced support for cross-chain interoperability. With Polkadot relay chains, bridges and parachains, arbitrary data could be encrypted with our dTRE technology and transferred across various blockchains, and triggered future events on any other blockchains. The Polkadot multi-chain network allows us to explore the full potential of our dTRE technology since it may be integrated with the whole web3 network and create a large number of new dApps.

    Our target audience is whoever needs to send a temporarily confidential message in the future. It could have a list of applications/businesses including but not limited to

    1. Decentralized strategy market (to replace the centralized service like tipranks.com )
    2. Decentralized prediction market (to replace the centralized service like predictit.org )
    3. Universal key escrow (encrypted arbitrary crypto key to hold the escrow fund and release in the future)
    4. Decentralized voting system (encrypted ballot and reveal it in the future)
    5. Decentralized blind bidding (encrypted all bids and reveal in the deadline to find the final bid winner)

    Any creators and developers with the above applications could be our target audience. For example, they could be parachains and dApps that provide decentralized trading platforms, strategy markets, prediction markets and so on.

    Essentially, the world needs decentralized reputations to open a new Web3 frontier. Our dTRE technology helps dApp dev and owners build up their decentralized reputations and creates marketplaces for temporarily confidential data. Therefore, the early access privilege to the dTRE data can be traded so that the reputed content creator can sell their strategies or predictions. Additionally, the dTRE technology can support a range of new Web3 applications that need features for timed data release.

    No, according to our best knowledge, we are creating all new decentralized applications in the Web3 domain. We don't see similar projects in blockchains providing decentralized timed-release encryption (dTRE) services. We believe that the dTRE technology will radically change many existing centralized applications since it builds up a trustless and permissionless mechanism to send a message to the future and create markets for early access or subscription.

    The Integritee Network pioneers confidential computing in Web3 as a project in the Substrate / Polkadot / Kusama ecosystem. It provides remote attestation services for us to build a fully decentralized tech stack. Although the TREX network uses the same type of confidential computing technology as theirs, the TREX network anchors on a different kind of service, working with another category of clients. We will eventually grow into two different types of projects in the same ecosystem.

    Development Roadmap ๐Ÿ”ฉโ€‹

    In the current stage, our first milestone is to deliver an early demonstration using confidential computing hardware for decentralized timed-release encryption. We will develop our first demo as a side-chain in a decentralized network that supports off-chain workers in TEEs. We request a level-1 grant for the early demonstration and will work on the next level in the following application. We have accumulated solid experience in development with the Substrate framework, so we believe that we can implement our network at a fast pace.

    At the next level, our second milestone is integrating the TOCW with our network under our particular consensus and mechanism. We will also implement key splitting as a third milestone to enhance the security and reliability of our system at the next level. Finally, our fourth milestone is the implementation of XCMP for cross-chain applications.

The key-holder worker is remotely attested by a decentralized network so that the worker node cannot manipulate the release of the encrypted data. The "key-holder" node will provide a key-holder service to hold the key piece inside the TEE and release it until it expired.
    2.TREX nodeA TREX core node provides pallets and APIs so that a key-holder can publish its remote attestation reports on the chain and other clients can access the report to verify its TEE. The TREX node also provides APIs to post timed-released data and expired keys to unlock those datas.

    @@ -22,7 +22,7 @@ The underlying oracle design will follow the same structure as Tellor on other chains, namely a game theoretic design where data is put on-chain by staked reporters who are liable to lose their stake if disputed. The system can be as fast as participants desire, but like other blockchain architectures, is more secure the slower the oracle use is since it allows more time for disputes.

    Tellor architecture of the smart contracts can be found in the TellorFlex github repository or in our whitepaper. Information on the Tellor Reporter (node) software can be found in the Tellor Docs.

    Prior work or research on the topic: The team received an Ethereum foundation grant for researching bridges as the team was initially designing a cross-chain decentralized derivative protocol. There were no available decentralized oracles at the time and that prompted the team to design and build a decentralized oracle, which soon was dubbed Tellor. Tellor has been live on Ethereum mainnet since August 2019 and the team has continued to iterate to increase decentralization, token dependency, and improve upon governance. We have launched on several chains as of May 2022, including Ethereum, Polygon, Arbitrum, Algorand, and corresponding testnets.

    What your project is not or will not provide or implement: Tellor will launch the system and help design/solve any specific integration for users in the substrate ecosystem. We will initially help bootstrap a network of reporters, however Tellor is a system that is designed to run without any team intervention. Being crypto-economically incentivized, reporters will stay in networks that provide enough incentives/rewards for them to provide data. Tellor can provide the software for reporters to run, however the size of the network will largely depend on whether users are active in the system and funding oracle reporters. It is important for the web3 ecosystem and tellor to work together to ensure enough usage and monitoring is enabled on the system once it is launched.

    Ecosystem Fitโ€‹

    Ecosystem Needs and Fit - For a long time the Tellor team has been fans of the Polkadot ecosystem and their pursuit of decentralization. The values of security, transparency, and truly open and decentralized networks is something that Tellor was built upon and lines up perfectly with the ecosystem built here. Oracles are a necessity for decentralized applications to meet their full potential and to expand the interoperability between chains. Although there are competitors, Tellor is an oracle built on the values which align with projects built on Polkadot. We provide the needed infrastructure for chainsโ€™ use cases to expand, while at the same time remaining uncompromising in our approach towards censorship resistance and decentralization.

    Target Audience - The target audience is developers needing connections to off-chain data. Whether itโ€™s connections to other non-XCM connected chains, or even straight web2 off-chain data, Tellor can provide the ecosystem with a general purpose oracle that can handle any data, at any speed, for any use case. The initial goal is for the Tellor oracle pallet to be included/added to parachains so that developers can use it to access off-chain data in any smart contract structure on the ecosystem.

    Similar projects - A similar project to Tellor is the Chainlink Substrate oracle pallet. Tellor also provides off chain data however, Tellorโ€™s design differs greatly in areas where it matters. Mainly, the Tellor oracle has a greater (actual) degree of decentralization, is crypto economically incentivized versus reputation based, and is completely flexible for the needs of any data type or frequency. In addition, once the network of reporters is bootstrapped, there is minimal team intervention needed. Anyone can become a reporter by staking, anyone can dispute the validity of the data for a fee, and the user can incentivize reporters to quickly add or replace the data they need by posting a reward. The system is permissionless, as well as sybil and censorship resistant.

    Future Plansโ€‹

    The TreasuryTracker analytics portal is set to bring a significant change to how OpenGovernance data is tracked, analyzed, and presented. However, the development of a proof of concept (POC) under this grant proposal represents only the first phase in our strategic roadmap for the platform. We have a comprehensive set of short and long-term plans intended to maximize the potential of this project:

    Short-Term Plansโ€‹

    After delivering a working POC, we plan to work on extensive user feedback collection and rigorous testing to further enhance and refine the platform. We aim to make necessary modifications and improvements based on this feedback to ensure the platform aligns with the needs and expectations of the community. Promotion and support will be crucial at this stage, and we intend to conduct extensive outreach to raise awareness about the project and encourage its use among our target audience.

    Long-Term Plansโ€‹

    As for the long-term vision, we plan to further expand the data collected and the analytical capabilities of the platform. This expansion will provide a broader range of data analytics. A particular focus will be put on enhancing the user interface and overall user experience inspired by our existing graphical mockups. The focus will be on presenting platform data in a more modern and user-friendly UI to enhance user interaction and understanding. This redesign process will prioritize clarity, ease-of-use, and intuitive navigation to best serve the platform's diverse audience.

    In addition to the live analytics side, we're exploring the idea of producing periodic reports (e.g., quarterly or annually) that provide a comprehensive review of the OpenGovernance referenda on Polkadot and Kusama networks. These reports can serve as invaluable resources for the community, giving in-depth insights into trends and significant happenings in the ecosystem.

    Ultimately, our goal is to make TreasuryTracker a go-to platform for all OpenGovernance data analysis and reporting needs. As the platform grows and matures, we'll continue to identify and explore new opportunities to further its reach and impact within the Polkadot and Kusama ecosystems.

    Project Overview ๐Ÿ“„โ€‹

    Our application seeks to fund the development of a monitoring platform for validator operators.

    Overview and Ecosystem Fitโ€‹

    Validator Monitoring Service is a monitoring platform designed to track the performance of validators in the Polkadot and Kusama networks.

    In the existing ecosystem of the Polkadot network, there is a lack of comprehensive historical information available about how validators perform as ParaValidators and their participation in consensus. Public scanners like Subscan offer limited insights into validator performance, with scarce information such as earned points and rewards displayed only after an era's end. This limitation prevents the use of existing scanners as real-time monitoring tools.

    However, active participation in consensus is crucial for upholding network security. Each consensus round relies on obtaining 2/3 precommits, and validators failing to reach this threshold cannot contribute to blockchain security. If numerous validators encounter participation issues, it can reduce block production speed, adversely affecting the overall network.

    We truly believe that every validator operator should understand their role and significance in ensuring blockchain security.

    Furthermore, the information provided by public scanners predominantly focuses on individual addresses and specific events. At the same time, it allows for retrieving on-chain data such as reward payments and rewards points for a particular account. Scanners generally lack the capability to compare these rewards with those of other validators. This limitation hinders a comprehensive understanding of a chosen validator's performance relative to others in the network.

    Our monitoring service effectively addresses this challenge by providing real-time data on validator performance and enabling performance comparisons with other validators.

    Moreover, besides public scanners, there are several existing solutions available for validator monitoring, such as P.A.N.I.C., Polkalert, B-Harvest, nmonpolkadot, Polkadot-K8s-Monitor, Polkadot-Watcher, ex-1KV Telegram Bot, as well as, grant-supported dashboards Cyclops. Our solution stands out due to several significant differences:

    1. Out-of-the-box Solution: Unlike many existing applications that require hosting arrangements, our platform offers a hassle-free experience. Users can effortlessly try our product and assess its suitability for their needs by simply interacting with our Telegram bot and setting up a live dashboard. This accessibility enhances the popularity and adoption of our solution.
    2. Comprehensive Data: While most solutions provide standard on-chain data such as reward points, reward amounts, and on-chain events like offences or payouts, our platform goes beyond that. We offer unique data, including information on participation in the consensus, the selection of a para-validator, and para-validator points per session (not just per era). This granular data provides users with a more comprehensive understanding of validator performance.
    3. Ongoing Support: Many existing applications are developed by small teams and may need more ongoing support, with some repositories needing to be updated. In contrast, we are one of the largest validators in the network, and we commit to supporting and maintaining our validator monitoring platform. Additionally, we utilize the same system for our internal purposes, ensuring its reliability and continuous improvement.

    Potential usersโ€‹

    Our monitoring system caters to various parties within the community who can derive significant benefits from its usage:

    1. Validator Operators: Our service is a valuable tool for validator operators, particularly small teams and independent validators who may lack the time and resources to develop their monitoring systems. For instance, meeting the strict requirements of programs like the 1KV program can be challenging for small and independent validators. With our monitoring system, they gain the ability to track an extensive range of metrics. By leveraging our service, validator operators can thrive within the decentralized ecosystem and enhance performance.
    2. Nominators: Nominators play a crucial role in the network by selecting validators to nominate. Our service provides nominators with detailed performance comparisons among different validators. They can evaluate critical metrics such as consensus participation, and block production efficiency relative to other validators. Our service empowers nominators to make informed decisions when choosing validators to nominate, optimizing their returns, and actively contributing to the network's health.
    3. Foundation: By having access to comprehensive information on validator participation in consensus, block production efficiency, and other crucial metrics, the Foundation can identify and address any security vulnerabilities or potential risks promptly. This proactive approach helps to maintain a robust and secure network for all participants. Moreover, the Foundation can offer greater transparency to the community regarding validator performance

    Lastly, our team possesses extensive experience in maintaining validators within the Polkadot and Kusama networks, and we have developed the necessary monitoring and maintenance tools. We firmly believe that this knowledge should be shared for the benefit of the entire network rather than being kept private. Therefore, we seek a grant to further develop our monitoring system and contribute to the network's advancement.

    Project Detailsโ€‹

    We have developed a comprehensive monitoring platform as a service. This platform provides validator operators with an effortless monitoring solution, saving them valuable time and effort. With our service, operators can focus on other critical aspects of validator operations, knowing that their monitoring needs are taken care of.

    Our system could be depicted in the following picture:

    Our current solution already offers a Grafana instance, which serves as a powerful dashboard. This dashboard displays real-time metrics of validators, enabling users to access and analyze the data easily. To simplify the setup process, we have integrated our platform with a user-friendly Telegram bot, @p2pvalidator_monitoring_bot. Through this bot, users can quickly configure their personal dashboards by selecting the validators they wish to monitor.

    The live dashboard provides users with a comprehensive overview of all essential metrics related to their validators. These metrics are updated automatically every 20-40 seconds, ensuring real-time visibility into the performance of validators. This rapid update frequency enables users to respond to any changes or issues that may arise promptly.

    Furthermore, we understand the importance of historical data in analyzing validator behavior and identifying potential issues. Therefore, our platform collects and stores data on all active validators for up to one month. This means that users have access to historical performance data, allowing them to conduct in-depth analyses of their validators over time. Such insights are invaluable for optimizing performance and addressing any emerging concerns.

    In conclusion, our monitoring platform provides validator operators with a hassle-free solution, streamlining the monitoring process and offering real-time and historical data to support informed decision-making and efficient operations.

    System workflowโ€‹

    A user initiates a conversation with a Telegram bot and selects from options such as creating a new dashboard or connecting to support. When the user inputs the validator addresses they wish to monitor on the dashboard, our system verifies the authenticity of these addresses, confirming that they belong to validators. Then, the system generates the dashboard and sends the user their access credentials. Subsequently, the system resets the client's session to prevent potential 'double' events. This involves preserving the user's current position in the workflow, for instance, preventing the triggering of a dashboard deletion before its creation.

    Upon receiving a user's request to deploy a dashboard, their specified validator addresses are recorded in a key-value file (values.yaml) associated with their Telegram ID and subsequently committed to Git. ArgoCD, set to check the repository every 5 minutes, will recognize if there isn't a Grafana instance associated with the particular Telegram ID and proceed to deploy a new instance. As ArgoCD prepares the dashboard, GitHub Actions concurrently monitors the availability of this new instance. Once the instance is fully operational, GitHub Actions triggers a notification to the client, providing them with their login credentials.

    Our data collection process is anchored on utilizing exporters from the Blockchain. These exporters operate incessantly, amassing raw data directly from the Blockchain. Each exporter functions as an HTTP web endpoint for the scrapper, supplying plain text with specific metric values. Subsequently, this data is channeled into the Victoria Metrics cluster using VM insert, which timestamps each value. Ultimately, designated data is selected by a specific dashboard (Grafana instance) using VM select.

    In our current implementation, we provide insights on the following key metrics:

    • General indicators: we track session/era progression and staking data.
    • Validator data per epoch: we provide information on rewards points, active validators, and their position in the active set.
    • Era and epoch points for ParaValidators: we monitor ParaValidator points earned and their relation to the network's average, median, and 95th percentile.
    • Finality metrics (GRANDPA): we track blocks' prevotes and precommits, and their ratio to ideally processed blocks.

    Development Status ๐Ÿ“–โ€‹

    Current service already offers a convenient and user-friendly experience through a Telegram bot named @p2pvalidator_monitoring_bot. This bot serves as the gateway to our comprehensive validator monitoring capabilities, covering various aspects of validator performance.

    At the core of our product, we have developed an exporter that takes raw data and translates it into a format compatible with Victoria Metrics, our chosen data storage solution. The data is securely stored for one month, during which it is transformed into meaningful metrics. These metrics are then transmitted to Grafana dashboards, providing users with a visually appealing and informative monitoring interface.

    Through the Telegram bot, users have access to a range of features. On the user's side, they can deploy a personal dashboard, allowing them to monitor their validators efficiently. They also have the ability to destroy their personal dashboard when needed. Additionally, the bot provides support options, enabling users to seek assistance and receive prompt replies.

    On the admin side, there are several options available for managing the system. These include the ability to deploy/destroy Grafana instances, and ban/unban specific users. Admins can also engage in support-related tasks, such as replying to support inquiries and closing support conversations as necessary.

    By utilizing our Telegram bot, users can easily interact with our monitoring tool, deploy personalized dashboards, access support, and enjoy a seamless monitoring experience. Meanwhile, admins have the necessary tools to manage the system and provide timely assistance to users efficiently.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Web3Go is an open data platform that focuses on the formatting, visualization, sharing, and collaborative analysis of the on-chain data generated in the Polkadot ecosystem.

    Due to the explosion of Defi, NFT, and metaverse, there is massive amount of data generated on the blockchain every day, which is very important information for the media companies, investment institutions, and blockchain participants. However, it is difficult for non-professionals to obtain and understand these data. Beyond all doubt, data is valuable. Our project is to build a data platform for the Polkadot ecosystem and provide a series of toolsets so that everyone can easily create visualized results of data analysis. We are able to track smart contracts on-chain, and various parameters like stakings and CDPs of different Defi protocols, NFT circulation, and cross-chain assets on Polkadot ecosystem, and make these data formatted and persisted. With the help of the smart contract on Substrate parachain, non-professionals can publish their data needs on the platform and use rewards to motivate professionals to help them perform data analysis; for professionals, they can publish their own professional analysis for everyone to use paid or for free. In the second situation, they can get the reputation from the community. In the end, we broke the monopoly of some existing companies on data analysis and interpretation, so that everyone can truly enjoy the true value behind blockchain data.

    We believe that with the development of Polkadot ecosystem, more on-chain data will be generated and the value behind the data is giant. Currently, there is still a gap between professional users and common participants in terms of the technical know-how of data. Using the infrastructure and tools provided by Web3Go, everyone can easily create, publish and share their point of view in the form of nice charts based on the real data which has been formatted from the blockchain.

    The interpretation and analysis of data should not be in the hands of certain centralized professionals, but rather all users should have a say and benefit from it. Our vision is to build a Polkadot-based data analytics infrastructure, toolset, and incentive system where everyone can publish and be rewarded for related data tasks. Finally, an open and free data platform will be built to surface the signals of what is happening in the Polkadot system.

    Project Detailsโ€‹

    Architectureโ€‹

    Componentsโ€‹

    1. Indexer: an indexer of blockchain is used to extracts the on-chain data and saves the data in the database in formatted manner. Since the Polkadot network is composed of relay chain and parachains, each parachain can define its own Event or call, so each indexer of the parachain must be adapt to its metadata. So there will be multiple instances of the indexer of Polkadot.

    2. Data Board: data board is the visualization result of data analysis created by analysts or community member, which can display the analyzed and customized information on the Polkadot ecosystem such as a token transaction or holders, an NFT transfer, and history of the transaction, the statistics of a Defi protocol, or some special event like parachain auction, and governance.

    3. Contract on Substrate: We will use smart contracts on the Substrate nodes to demand, publish, share and reward the data activities within Web3Go. There are primarily two kinds of players involved in the smart contract: data demander, who has a need of professional, visualized results of data analysis regarding events that happened on the blockchain. Data demanders will publish the needs through the contract with bounty to incentive whoever fulfill these needs; on the other hand, data analyst, who has professional knowledge and skills can take on data tasks, or they can publish and share any data board they have created to the community in a paid or free manner. This smart contract will incentive more people to contribute to the data activities in the ecosystem since those who create more valuable data boards will gain a higher reputation.

    4. Query Module: The data query module provides a user interface to the data analyst to generate data boards. Because data stored on the blockchain is in the form of key-value pair, it is very hard to use and analyze the on-chain data directly. With the UI provided by the query module and along with the chart display module, the analyst can take advantage of the formatted data and visualize it in an automatic and customizable manner. The data will also be automatically synchronized with the blockchain, so updates will be reflected on the data board in real-time.

    5. Chart Display Module: The chart display module is used to visualize the result of data analysis and is the main component of the data board. The chart display module can provide different charts like bar charts, pie charts, scatter plot, and so on.

    6. Subscription Module: For each created data board, the data demander of this data board can subscribe to the notification signaled from this board. The notification can be triggered by a big transaction of a token or an APR vary of a Defi protocol. This module provides the functional for the subscription.

    7. Label/Tag Module: this module will give the address different labels basing on its historical activities on the blockchain, e.g. token transfer, Defi participation, etc. It is survied that at least more than 50% of the total addresses on Blockchain are inactive. So this module will filter the active address according to its activities such as "Big Whale", "High Activity" and so on. The labeled addresses are a very good dataset that can be monitored to signal what is happening on the blockchain.

    8. Data Mining Module: data mining module is used to look for regulations and patterns in large batches of data come from blockchain. data mining is widely used in some traditional industries like Retail, manufacturing, financial and financial insurance, but we believe that this technology will benefit the blockchain industry as well. The module will dig through historical data to discover hidden connections and predict future trends in the specific area of the blockchain, like token price prediction, Defi earns prediction, etc.

    9. Community Module: The community module is a public place where data activities participants can communicate. For example, data demanders can publish their demands, the data analysts can take on the tasks or share their own data boards, and the most welcome data boards will be listed here.

    Technologiesโ€‹

    • Subquery is a blockchain indexer for Polkadot, Kusama, and other parachains. We will rebuild and customized this framework to fulfill our requirements.
    • Node.js
    • Docker
    • Substrate
    • Rust
    • Machine Learning
    • Python

    PoCโ€‹

    A web application with three data boards has been built as a proof of concept. We have used the architecture mentioned above to index three kinds of tokens: LIT, ATA, and POLS. With nice charts and tables, the transaction, holders are visualized and some addresses have been labeled according to the labeling rules; the second data board lists the crowdloan event on Kusama networks. This data board lists the contribution and participants for each project which attends the crowdloan event; the third data board tracks the CDP(collator debt position) status of Karura lending system and provides the real-time status of each account.

    Ecosystem Fitโ€‹

    We have found several successful data analysis projects in the Ethereum ecosystem. Each project focuses on a specific area: Defi tracking, token tracking, wallet profile tracking. But currently, there is no data analysis project designed for Polkadot. Due to the unique structure of the Polkadot network, there will be more interesting data generated in the network, so we believe the whole community needs a data analysis tool as soon as possible.

    Similar projects

    What makes us different is,as a part of Web 3 community and Polkadot ecosystem:

    • The first project focuses on the data analysis for Polkadot world
    • Designed to let everyone can benefit from the value of data in the Polkadot world and make the valuable data public to everyone, not in the hand of one centralized project
    • An incentive mechanism that gets everyone involved and participates in the data activities.
    • A comprehensive analysis not only focuses on one area but will include all data like a cross-chain asset, governance, auction, Defi, staking, and token.

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can use the existing data board, and use the UI to create/publish their own customized data board

    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish an article/workshop that explains the concept and vision of Web3Go
    1.aIndexerWe will develop our customized indexer on the top of Subquery to make it more compatible to our scenario in below two areas: 1. Handle data/event and extract the result to external storage: currently the indexed data is saved in the built-in Postgres database due to the design of the framework of Subquery. And we have to retrieve the data from Postgres to our database again, it is very inefficient. We are going to build two new modules: the post-process module and the logic handling module, which can directly save the data to our database directly according to our logic module. in this way, the data and logic part can be decoupled.
    1.bIndexer2. Enable HTTP/HTTPS module to retrieve external data when fetching block: currently, the framework does not support retrieving data externally during fetching the block. But this case happens from time to time: retrieving the NFT metadata from IPFS can be one example. We will implement this module on top of the Subqeruy existing framework.
    2.UI Module:general WebAppWe will continue on the development of the web application to implement: user sign-in/sign-up, categorization of data board, social interactions functionality including like and share, subscription of a specific event comes from a specific data board, UI redesign and refinement, documentation and tutorial.
    3.3 more Data Boards:We will create 3 more data boards of other projects in Polkadot ecosystem that have already won the bid in the Kusama auction(or Polkadot auction if it happens), so we will have more valuable data boards on our platform and user collect their board basing on our data and tools. Three projects are planned to index: RMRK(NFT circulation), Moonriver(stake tracking) and Parallel(Defi tracking). (The projects might be changed but the number of data boards is fixed)
    4.UI Module: semi-automatic chart generationThis part is the core value of Web3Go, which can help users generate charts based on existing data. We will optimize the UI and make the chart more charming and easy to use.
    5.Support more Kusama Token:We will support the token analysis for KSM, MOVR, KAR, kUSD, Heiko instead of ERC20 token.

      2.UI Module:fully-automatic chart generationWe will enhance the user interaction of generating charts, provide the "drag and create" module for the user to generate charts. In this case, the user can generate charts with the same complexity as writing SQL can do. This functionality will provide a more easy way for the user to generate complicated charts who does not know program with SQL.

    Future Plansโ€‹

    • As our vision is to let "everyone enjoy the value behind the blockchain data", we will design the token economics to let more people involved in the whole data board activities. The rough idea is to design three kinds of roles: data demander, data analyst, and data validator, and introduce the token incentive to incentive the community to create more customized and interesting data boards, and this will be done through the parachain system. We have already started doing the research on the token economics design, and after this grant is finished, parachain development will be started.
    • As our team is a sub-team of Litentry, so we have a strong development team , operations team, a 60k+ community, and have a good relationship with most of the projects in the Polkadot ecosystem. All of the above has provided us a strong foundation of success. we want to be the best data analysis project in the Polkadot ecosystem, and even collect more data across other public chains in the future.

    0b.DocumentationWe will provide inline documentation of the code and basic tutorials. It explains how the team creates predictions and how users make predictions.
    0c.Testing GuideWe will conduct unit test on all modules to ensure they can function properly. In this guide, we will describe how to run these tests.
    1.Creating proposal moduleThis module provides a method for creating prediction proposals using specific parameters, such as prediction topics, options, settlement currency, transaction fee ratio, and prediction period.
    2.Prediction participation moduleThis module provides the functions of using settlement tokens to participate in predictions, swapping prediction tokens, and providing and removing liquidity.
    3.Results uploading moduleThis module provides the function of submitting results through stake node.
    4.Market settlement moduleAfter the results are officially announced, users predicted correctly can exchange their prediction tokens with settlement tokens with equivalent value.Users who provide liquidity automatically remove liquidity after the end and share fees.

    Future Plansโ€‹

    1. In the second phase of the product development plan,multiple incentives are designed for users. In addition to gain rewards by predicting correctly, users also have rewards for predictive mining, staking, predicted leaderboard, liquidity providing and yield farming, and etc. Also, there are additional rewards for prediction topic creators and community nodes. The specific rules of this part of the reward are introduced in the white paper.

    2. In the third phase of the product development plan.The platform will open up community autonomous nodes, and reporting and supervision mechanisms. Each user will be able to become a governance node by staking governance tokens. The governance node can upload the results and share the revenue from withdrawal fee. The governance node is authorized to upload results and accept the supervision of the entire network. When the result submitted by the node is different from reality, any user can initiate a report through pledge, the reported person will be punished, and the reporter will be rewarded.

    3. In the third phase of the product development plan.Optimize an easier-to-use stake node. In order to encourage more non tech-savvy users to explore the stake node, we will develop a graphical operation interface for the common users to upload results after staking tokens, pass the review and become a staking node.

    4. In the third phase of the product development plan.Add the governance voting pool of the parameters and development of the platform it self. The range of voting concludes the settings of some parameters of the platform, future revisions, iterative upgrades of the platform, such as adding new features.

    5. In the fourth phase of the product development plan, a more designated and user-friendly dashboard will be added to display platform statistics.

    6. In the fourth phase of the product development plan, More than simple prediction, it is a way for actively socialize and interact with passion. Users will be able to discuss topics by predicting topics, and join a forum-style communication system, with social functions such as friendsโ€™ group and group chats.

    We have been heavily involved in learning all things associated with the Polkadot & Kusama Ecosystem. This has been coupled with the idea of bringing land and property from its current state into the web3 ecosystem. We have been meeting with top-level industry leads, government officials and developers. Robin Ejsmond-Frey and Nico Morgan from Parity have been a tremendous help by supporting us with information about the W3F grant application process and recommendations to attend Hackathons and the Polkadot Decoded Event London. As well as as number of forums to help our substrate development knowledge.

    We have been taking time to play with Substrate to form initial local nodes. We feel we are now ready to build the initial POC for this project in the Rococco test environmenment.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 โ€” Initial POC of lending protocolโ€‹

    We will build on the excellent work we have achieved developing the Real Estate NFT marketplace for the hackerearth.com hackerthon.

    In the first milestone, the features for the PoC will be implemented and tested by limited users. We will adapt FRAME pallets to create a unique structure of a central community loan pool that acts as a risk reducer to allow individual loan stakers to lock and unlock native XCAV coins quickly and easily, rather than being committed to the full term of a particular loan. This will provide an attractive low risk investment opportunity and increase community confidence in the network while eliminating any delay in providing the funds to the real estate development project, once all the necessary checks have been completed. This loan pool structure could be applied to many different chains in future projects. The execution of various stages of the dApp specific logic will built using ink! smart contracts.

    3.Loan management pallet Manage loan application Land details' Registration Manage loan interest percentage * Based on land and experience Approve/Reject request
    4.Staking pallet User can stake native token Calculate APR * Distribute payouts
    5.DAOThe PoC will have a basic voting structure to ensure rewards can be given to the real estate build stage checkers (As we progress in to the MVP stage this will be expanded to form a full governance structure).

    Future Plansโ€‹

    We are talking to Subwallet about integrating the KILT protocol DIDs in to their wallet for a smoother and simpler user experience. Once we have built the initial POC then on to the MVP and GTM. We have already started the white paper as well as developed a pitch deck to demonstrate the potential of the system to; investors, partners and eventually XCAV coin holders. We have started a social media campaign in order to build a community now and through the dApp build & testing stages.

    • Payment Address: Ethereum (USDT/USDC) 0x5E1257E928aa42E3D0cd9E2A7537E37D108D811B

    • Level: 2

    Overviewโ€‹

    Blockchain adoption is happening at a very rapid rate, with a lot many use cases being implemented and seeing the light of the day. The concept of the parachain enables the possibilities further. While we focus on building the use cases, code them and implement the business logic of it, including the creation of Parachain and then further logic running upon it, we majorly underestimate the DevOps activity to deploy, maintain, scale and manage the parachain itself. This includes initial launch of the parachain, its thorough testing using Zombie-net and scaling it further by providing support for users to create and deploy validator, full and archive nodes with ease as well as to have secure RPC endpoints. The most deficit we see is around advanced analytics and proactive monitoring to ensure a production grade incident management of networks and nodes.

    Project Detailsโ€‹

    Zeeve will provide a GUI tool to setup the new Substrate zombie-net network with in-depth and flexible configurations in few clicks supporting K8 and native VMs whichever fits the parachains better.

    A GUI will be built to allow a quick setup of the relaychain, parachain with zombie-net with the desired capabilities to test multiple configurations. This in turn will allow the developers and parachain teams to try multiple chain configurations while setting up the parachains with Zombie-net, as well as to choose different nodes to try and test for the best possibilities on the parachain.

    This not only will allow configurations on the parachain side but will also allow you to pick from a set of predefined DSL templates on Zombie-net as well as upload the new templates without needing to write the code. The graphical control panel will support all the other configurations or operations required to enable the developer or parachain team to test with as much flexibility as required. These operations include:

    • Start - Start the network with configured info (templates)
      • Start the network for either evaluation or testing
    • Delete - will stop the processes and delete it
    • View Info - view execution logs and command

    Test result and logs

    The interface will allow the developer to test and see live logs of the test run, post run results and logs on the aforementioned interface. Furthermore, a stack of Prometheus and Grafana will allow easy monitoring of the Zombienet.

    Templating

    The control panel will also allow the developer or the parachain team to one-click replicate one of the existing zombie-net configurations, save as template or pick from previously saved template and re-create a new test with some rapid tweaks to it.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    We define ZeroDAO as a public resource, including a social network, a reputation system. the ZeroDAO social network solves the incentive dilemma that currently exists in blockchain social networks, while incentivizing good behavior makes good behavior disappear. Imagine what Twitter would look like if you could get $1 for posting a tweet. Two-factor theory even concludes that security, salary, fringe benefits, good pay is not Motivators but Hygiene factors. Hygiene factors that do not give positive satisfaction or lead to higher motivation.

    ZeroDAO social network solves the incentive dilemma by amplifying social motivation and internalizing external motivation.

    In the ZeroDAO network, we still quantify user contributions and settle them into Tokens, which we call social currency. It is frozen and at some point assigned to users trusted by the owner, it is also social currency and goes on to be shared. The user's social motivation is amplified. We use to shared information, now we share value.

    ZeroDAO social network brought us the reputation system and we proposed the TIR algorithm to compute the graph and obtain the reputation of each user. TIR is difficult to compute but easy to verify on-chain. This feature makes ZeroDAO's reputation system completely decentralized. At the same time, it has strong ability to prevent Sybil Attack to meet the security needs of financial products and on-chain governance. ZeroDAO also brings credit finance, zero-cost payments, and other applications to the blockchain.

    Project Detailsโ€‹

    Social Networkโ€‹

    1. The application quantifies user contributions and transfer social currency to A. Pending Token is frozen and cannot be used.
    2. The system periodically distribution of A's social currency to its trusted [B,C,D]. A small part of social currency is unlocked to the owner.
    3. Forming a value-sharing network. B, C & D also share their social currency, forming a value sharing network.
    Social Currencyโ€‹

    • Reserve Reserve the owner's free balance. The percentage can be adjusted by the community.
    • Share Transfer to the social currency of users trusted by the owner.
    • Fee Analyst's fee.
    • Burn Share to all users.
    • Reward pool Used to solve the verifier's Dilemma.

    Reputation Systemโ€‹

    TIR( Trust-Influence-Reputation ) Algorithmโ€‹

    The TIR algorithm is inspired by Google's text retrieval algorithm for search engines. It is used to replace the vulnerable PageRank algorithm and has similar capabilities to TrustRank, but is simpler to compute and requires no iterations. TIR draws on its idea by finding high-impact users in the network as seed users, setting the highest score for them, and then passing the reputation on to other users through trust relationships.

    The TIR algorithm relies on two assumptionsโ€‹
    1. High-influence users are less likely to trust fake users
    2. The longer the trust, the more credible it is
    Procedures of calculationโ€‹

    1. The set of nodes with the largest number of passes through all the longest shortest paths in the graph is selected as the seed users. The larger the network and the higher the account retention amount, the more difficult it is to cheat.
    2. For example, we want to calculate the reputation of user D.
    3. Set the reputation of the seed user to ๐‘…max , get the reputation of the seed user in the last round ๐‘…seed0.
    4. Calculate the shortest weighted path Seed -> A -> D from the seed user to theD user.
    5. The path weight is the natural logarithm of the difference between the reputation values of the two users in the last round, and the minimum value is 1.
    6. Calculate the reputation ๐‘…a1 passed at node A : Take the initial reputation value of Seed, divide it by the number of users Trusted by Seed, and divide it by the path weight.
    7. Calculate the path weight from node A to node D in the same way and calculate the reputation of the final pass to node D. The sum of the reputation values of all seed passes is the final reputation of the target user.
    Easy to verifyโ€‹

    The TIR algorithm is extremely resource intensive to run on the blockchain, but verification is very simple, with the core verification requiring only 20 or so lines of code in substrate.

    Sybil Attack resistanceโ€‹

    So far, the algorithm is still not able to prevent Sybil Attacks.

    The algorithm will pick to cheat nodes when the attacker constructs a graph that is more favorable to it (e.g. more fake nodes and trust). Although we can raise the cost of an attack by setting higher account retention balances, raising fees, or raising gas, and expecting the network to be large enough so that the attacker does not have enough wealth or benefit to attack the network. But this also raises the cost for honest users, which is not elegant, and does not guarantee mathematical security.

    Hall of Fameโ€‹

    ZeroDAO uses a simple approach. By electing the Hall of Fame through the community, the distance from the Hall of Fame is added to the seed selection algorithm. The attacker has zero or very little reputation, while users who need more than a certain reputation can participate in the election. The attacker cannot join the Hall of Fame and cannot be seed, and the attack fails. We computed circles, a social network with 100,000 on-chain users, which was also subject to sybil attacks. We selected only 20 Hall of Fame users and the algorithm worked well. You can find the calculation results here for round3 without the Hall of Fame, and round4 with the Hall of Fame.

    challengeโ€‹

    The reputation system is implemented through a challenge model. The system has two roles, analyst and validator. The analyst updates the reputation after staking. The validator monitors the correctness of the data and can challenge the result after staking and upload the path. At this point the system still does not compute the path. Other validators, if they find errors in it, only need to point out errors in individual paths. The system verifies the calculations and determines who is correct at this time. The sub-challenge mode significantly improves the efficiency of the system.

    collusion attackโ€‹

    Collusion only affects social finance and has little to no impact on reputation systems. The collusion attack here is the unlock of social currency that should be frozen through dishonest trust relationships. First, ZeroDAO allows users to not share, just like in the real world, where they have the right not to share but lose certain conveniences in using the eco-product. We have the following options.

    • Minimum number of trusts: For example, if Alice trusts 3 users and the minimum number of trusts is 20, then the amount allocated to each user is not 1/3 but 1/20 of the total amount. the remaining part is waiting for the next allocation. So users who do not want to share only need to trust as few other users as possible. After the minimum trust number is exceeded, the amount will be split very small and transaction costs (gas) will become significant.
    • Burn: Partial burn substantially increases the cost of evil nodes.
    • Front-end SDK: Wallets or security agencies can monitor user behavior off chain, give warning messages in the UI for risky users, and prevent other users to trust.
    • Negative propagation: The TIR algorithm supports propagating negative values to users who trust the evil user.

    Applicationsโ€‹

    The social finance, reputation system and zero-cost payment will lead to many exciting applications.

    • Traditional social network transformation: The ZeroDAO network doesn't care where the Dapp's data is stored, so it is very adaptable and traditional social networks only need to add a Trust button to connect to the ZeroDAO network.
    • Radical Social Network: Reputation systems and trust relationships make possible a new model of social networking, and we propose a reverse communication social network, where users post content that is not pushed to the feeds of their followers, but to the feeds of their trusted people. This may sound difficult to understand, but if you look at it in detail, you will see that this is an exciting new social network, as explained in more detail in the light white paper.
    • Governance: Sybil have been blocked, and now you can safely use the Quadratic Voting (e.g. Quadratic funding platform). You can also go experiment with more interesting modes of governance.
    • Super Bank: Super bank is another banking model other than central bank, commercial bank. It runs on blockchain through smart contracts, it has credit financial capability, directly facing users, instantly sensing user behavior, and adjusting interest rate with every transaction. It has deterministic expectations, including a flexible total amount of issuance, deterministic interest rate changes, and therefore can effectively sense the economic crisis. Even in the event of an economic crisis, he possesses deterministic self-recovery. It is finding equilibrium in every transaction, so there is no Minsky moment.
    • Zero-cost payment: A payment model where the user didn't pay anything. Especially when the minimum trust number is exceeded. Social finance includes institutional accounts, which do not participate in the calculation of the reputation system and are allocated the amount directly to the free balaner. users have nothing to lose in the payment process, thus increasing the participation rate of the charity. It is very useful in other donations, such as donations to open source communities. However, it is currently limited to payments to trusted institutions, and large-scale commercial use ( e.g. in pay-per-month music applications, decentralized storage payments ) needs to Solving collusion attack.

    Ecosystem Fitโ€‹

    Social Networkโ€‹

    There are about 20+ well-known blockchain social networks, which we did research on in 2020, and ZeroDAO's social network is different from them in the following ways.

    ZeroDAO social finance is the underlying economic systemโ€‹

    We don't care about the product form of the social network, whether it has comments, how the content is presented, how users interact, etc., or how he stores it, whether it uses IPFS or exists on its own servers. We only work on the more core and underlying economic systems and user relationships.

    ZeroDAO's incentive model has been radically improvedโ€‹

    Reputation Systemโ€‹

    A reputation system built on a blockchain essentially refers to the extent to which the system can trust a user. A reputation system in a broad sense includes identity verification, credit rating, and so on. There are a very large number of projects that intend to build reputation systems, and there are several broad categories, each with corresponding case; for the sake of brevity, specific applications are not listed here.

    • Evaluation: Two types are included, one with specific purposes, such as evaluation between buyers and sellers in a buying relationship, evaluation between DAO collaboration members, evaluation between demand and supply sides in a Witkey system. The problem is the low coverage and poor data standardization. The other type is voting without a specific purpose, which suffers from the problem that users lack a fundamental motivation to vote. Overall, it is also a good direction if there is a simple and effective enough way to counter attacks and standardize all data from an ecological point of view. In comparison, ZeroDAO has more coverage, more uniform data, and more security.
    • Personal Currency: Applications based on personal currencies are usually able to guarantee the validity of the relationship through certain economic models. This is one of the better categories to build a reputation system, and in fact, ZeroDAO's previous solution used exactly this approach. Each user can issue a personal currency and add liquidity in the form of x * y = k. A trust relationship graph is constructed between users through a complex economic system. However, in discussions with the community, it became clear that we were imposing too much responsibility on users, making them very confused about the act of trust. The most fundamental problem with this approach is that its security relies too much on the design of the economic system and always assumes that the economic system works perfectly. In fact, the incomplete contract will induce to constant problems in complex economic systems. The economic system would have to be tired of tinkering with and making the economic system more and more complex. We have abandoned this approach.
    • Social Network: ZeroDAO's reputation system is built on top of that. Most blockchain social networks claim to be able to build reputation systems. But computing centrality on-chain consumes too many resources. When the network is large, it is still too expensive even for Off-Chian Workers. ZeroDAO combines an economic system with the TIR algorithm to achieve a truly high-availability, sybil-resistant reputation system.
    • Other: It is also possible to build a reputation system by means of a computational marketplace similar to TrueBit that computes some kind of data on a large scale. There is already a peer-review based project being built. However, TrueBit's calculation method itself has some limitations.

    ZeroDAO reputation system is positioned as the core of a on-chain reputation system to meet the needs of most applications and has a high adoption rate. It is simple and reliable and does not require cumbersome operations for users. Third parties can also add other reputation systems on top of ZeroDAO reputation system according to their needs.

    Algorithm validationโ€‹

    We built a simple application to validate the algorithm and perform tuning, and show the results of the computation. It synchronized Circles-UBI on-chain user data and relationship data from theGraph, and we simulated the calculation of reputation for all users using the TIR algorithm and also calculateds Betweenness Centrality, PageRank, Article Rank, Degree Centrality, Harmonic Centrality, Eigenvector Centrality, Closeness Centrality.

    We computed data at different data sizes several times in our development environment. And a website was deployed to demonstrate how the selection of Hall of Fame users affects the calculation. You can also query the reputation of any user in the application, as well as the shortest path between users. We are still tuning the algorithm, so if you find significant deviations in the data, please contact us.

    Project Descriptionโ€‹

    ZeroPool is the first fully anonymous solution for the Ethereum. One can deposit, withdraw, and make transactions inside the project. ZeroPool supports ERC20 and ERC721. We hide the whole graph of the transaction. Gas cost is pretty attractive in our solution (15-40k per transaction), because we are using optimistic rollup.

    All these points explain benefits for the community. True anonymity on the blockchain becomes possible with ZeroPool.

    We are interested in cooperation with Web3 because we will be able to make zkSNARK and privacy technologies more attractive and clear for developers. Also, we will be able to attract more users and attention to our project.

    Private transactions are a rather atypical development for blockchain. There are two differences from common dApps: our dApp needs to manage local client/browser-side database and zkSNARK prover requires heavy computational complexity. We need to optimize the solutions not only at the opcodes level and algorithms but also at a more high level, like interactions between all components (UI, cryptography, local database, blockchain).

    Here is a tech description, how our solution works: State of Zeropool - scaling anonymous transactions for Ethereum.

    Distributed Tracing + Remote Execution.

    Zombienet incorporates Distributed Tracing tools from Grafana Tempo+Jaegar, which are well matched to XCM's recursion capabilities. At present, reasoning about what is going on between chains is accomplished by looking at a lot of raw logs and undecoded messages between chains. Substrate chains that operate as "shards" or on each others unique functionality will increasingly rely on remote execution, but this future cannot be realized until tools exist. Zombienet with Zombienet explorer aims to serve this goal.

Someone who knows only a bit of Javascript+SQL and completed their first Substrate pallet should be able to add their own chain indexing and user interface to Zombienet Explorer and do simple mysql analytics. We have about 5-10 key big classes so Level 7 fellows aren't required to achieve this goal.

    Zombienet

    After adding XCM Remote Execution indexing for Moonbase Alpha/Beta, we thought it would be possible to do a Shiden-Moonriver bidirectional remote execution (using Astar remote_transact and Moonbeam 5004 System Contract), but there is significant complexity in derived accounts in this case. Astar's Dino Pacandi led us to explore XCM Remote Execution within Zombienet following this; Moonbeam's Gorka provided 2 Moonbase configuration included here. From this effort, it became clear that complex XCM interoperabilty testing between parachains would be done in ZombieNet and a more extensible ZombieNet explorer would be required.

    Development Status ๐Ÿ“–โ€‹

    Development Roadmap ๐Ÿ”ฉโ€‹

    Zombienet Explorer code is a simplified version of Polkaholic.io run entirely in a local environment (local Mysql, pure Docker). Most of the engineering work thus consists of deleting all code that is useless, documenting what remains to support Substrate devparachain contributions, and testing that the Zombienet explorer is useful specifically to support parachain developers testing their single chain, and multiple chains interacting with other with XCM Transfers and Remote Executions in EVM + WASM contexts.

    Beyond having a clean and well documented Zombienet Explorer code base, we have 2 key demonstrations:

    0a.LicenseGNUv3
    0b.DocumentationProvide inline documentation for (a) all working chain parsers (b) XCM indexing mechanics
    0c.Testing GuideUpdate README of how the chain parsers actually work, with astar (WASM) + moonbeam (EVM) as core examples.

    1.Support for 2 Parachain ParsersDevelopment of 2 Parachain Parsers: Astar + Moonbeam
    2.Test 20 Zombienet ConfigsGenerate a report of our attempts to have working single parachain TOML beyond Shibuya + Moonbase with 20 TOMLs, using binaries available from our full nodes

    In the construction of Polkaholic.io, we have implemented generic parsers for popular pallets used by multiple chains (e.g. xTokens, polkadotXcm, xcmPallet, tokens, asset, system etc, assetRegistry) but found it was difficult to do this for all parachains: there is just too much custom activity.

    In our vision, parser for commonly-shared pallet only needs to be implemented once. Developers are welcomed to submit PR for commonly-shared generic parsers which have high impact. In addition, each parachain team can also tweak certain aspect of the indexing machinery + supporting UI for their own parachain by building a chain-specific parser for their own purposes and adding it to Zombienet Explorer.

    We will develop 2 representative parachain parsers: Moonbeam + Astar that demonstrate how substrate developers can extend the Zombienet explorer to support their own pallets and parachins.

    We will also test 20 Zombienet configurations using recently compiled binaries. See Zombienet Substrate Block Explorer - Milestone 2 for an exhaustive list.

    Future Plansโ€‹

    Colorful Notion aims to see this project have contributions from as many Substrate parachain teams as possible, similar to how parachains submit PR to Polkadot.js, except specifically with chain parsers + UI views added by more parachains. Our expectation is that by having parachain specific code developed by parachains, we may have this functionality brought back into Polkaholic.io's multichain block explorer and other projects that need to do analytics/UI.

    With sufficient interest as different parachain teams instrument their parachains for XCM interoperability, we would welcome doing follow on work on:

    The basic part of the open-grant has been developed as framework for our flagship game, as we where focusing on the game it self the API lakes inline comments and might be a little complicated to jump in with out a good documentation or tutorials.

    A lot of our previous work on the World of Mogwais is being used as PoC for the current project, the game logic we created WoMNetCore is reused where it makes sense or refactored to match better, here an old PoC. We used the CryptoKitties on Substrate as our first crash course into Rust and luckily it had a theme in common with our vision from 2017 old whitepaper.

The storage items include all the stores we will need (not 100% decided yet) and mapping storage for OperationVersion <-> Operation.

    Operation - op_fileโ€‹

    We will create an Anagolay operation called file. This operation can take a string or a file buffer. In the case of the string, it will read the file and return the file buffer instance, in the case of a buffer it will return the correct instance. This way we can make sure that all targeted environments are using the same file reading approach and correct return data. Of course, the wasm will accept the ArrayBuffer and it will be correctly returned for any other operation that is executed after in the browser environment. Nodejs and Rust can simply pass the file path as a string and the op_file will read it.

    NOTE: All the apps, Nodejs, and Rust demo crate when executed must produce the same CID. WHY? Because if they use the same data and the same Workflow they must produce the same output. Same Workflow means using the same Operation manifest which means using the same Operation Version. 100% the same code execution!

    Substrate module - an_workflowโ€‹

    We will be implementing the an_workflow pallet which will contain extrinsics and storage. This pallet is used to store and retrieve the Workflow manifest which is then used by developers to create or verify the set of proofs. The Workflow execution depends on this pallet and its storage. For Workflow explanation click here.

    Anagolay CLI: Workflow manifest generationโ€‹

    We will build an interactive CLI which will be used to generate the Workflow manifest, validate it and store it on the chain. The CLI will be written in Typescript for Nodejs environment and published on IPFS and maybe NPM. The exact structure is not yet defined but here is the idea of what it should look like:

    We will create an Anagolay operation called op_cid. This takes any Multihash type and generates the CID with the multicodec set as RAW and the multibase set as base32.

    Operation - op_multihashโ€‹

    We will create an Anagolay operation called op_multihash. The Operation takes a buffer and creates the multihash instance. Possible multihashes will be sha2-256, blake2b-256, and blake3

    Workflow: executionโ€‹

    Execution of the Workflow manifest created in #3. We will implement basic recursive and automatic execution of the Workflow only for SYSTEM Operations. The execution will load all the dependencies and execute them in the correct order. We will NOT implement any kind of optimizations like caching or memoization to gain a boost in speed.

    Future Plans

    Later, we will implement the social aspect of the Operation and Workflow credibility creating the revenue streams for developers who will be testing the Operations and the developer who creates the Operation. This is part of the Reputation system for the Developers, Operations, and Workflows.

    Project Overview ๐Ÿ“„โ€‹

    Ares is a predictive machine project based on Substrate, with the trustless and verifiable under chain real data use a decentralized approach for smart contracts, parachain or other projects in the ecosystem of the Polkadot.

    It is a decentralized oracle network that consists of oracle pallet for parachain and validator, aggregator, reputation council pallet for Ares chain.

    Overviewโ€‹

    Ares consists of parachain plug-in, validator, aggregator, reputation council, proof of fraud. If parachain use our services, it needs to integrate our oracle pallet, The result of the request passed to the caller through a callback. We scan the parachain events caller about the pallet in our chain, use rpc or websocket request via off-chain worker, Aggregators randomly selected through VRF, which aggregates data from multiple sources. and submitted data to the parachain via extrinsic. Aggregators packing parachain extrinsic and receipts in ares chain via off-chain worker.

    img

    Aggregator needs to pledge certain assets, Every time the aggregator submits a correct data, its reputation value will grow. The reputation value and pledge will be weighted, from which we choose the members of council. council can only approve and reject proof of fraud submitted by validator. Default is to approve, the council does not need to work on every block, only needs to deal with disputes when validator fraud proof arise. Validator nodes can verify, if validator found the data is incorrect, submit proof of fraud to council. if council check up, ther it will reward validator and slash aggregator, its reputation will be degraded.

    The functions of aggregator committees are similar to Babe, and reputation council are likely Grandpa which finality the correctness of the data. Most nodes can become member of aggregators committees. It only takes few tokens to staking. The validator who submit proof of fraud need pay a small fee, it protects against DOS attacks.

    Project Detailsโ€‹

    Ares is designed as decentralized oracle network. First of all, Ares will provide basic ares pallet runtime which allows substrate built parachain/blockchain to interact with.

    • define ares Trait which contain Event, Callback.
    • define storage operator, request, result and error types
    • request external data, contains parameters and methods for how to request them.
    • describes how to integrate into parachain.
    • Aggregator scans the extrinsic in the parachain, use off-chain worker requests the data, and submits result extrinsic to parachain.
    • Aggregator packing parachain extrinsic and receipts on ares chain.
    • Validator validate data and submit proof of fraud.
    • Council reward and slash according to proof of fraud.
    • Aggregator, Validator, Council use off-chain worker getting external data

    Ecosystem Fitโ€‹

    Although the Off-chain worker can do part of the oracle job, However it can't guarantee the authenticity and reliability of the data, Ares can provide randomness and correctness of data sources through multi-party data aggregation and anti-attack and auditing of data sources

    SCALE Codec Implementation

    This document is referenced in the terms and conditions and therefore needs to contain all the required information. Don't remove any of the mandatory parts presented in bold letters or as headlines! See the Open Grants Program Process on how to submit a proposal.

    Project Description ๐Ÿ“„โ€‹

    SCALE is a lightweight codec for binary serialization and deserialization used in Substrate. Currently there are Rust, Python, Golang, C++ and JavaScript implementations of the codec. The goal of the project is to deliver AssemblyScript implementation as a separate library.

    The library will be required for encoding/decoding Polkadot Wasm Executor <> Wasm Runtime blob calls and more specifically:

    • Wasm Runtime blob compiled from AssemblyScript parsing runtime function calls from the Wasm executor.
    • Wasm runtime blob compiled from AssemblyScript calling the Polkadot Runtime Environment API (Host API).

    The library is a prerequisite for an AssemblyScript framework that generates runtimes or any runtime implemented in AssemblyScript loaded into a Polkadot Host.

    LimeChain is a blockchain-agnostic development company with a strong focus on developer tooling. We see Polkadot as an exciting technology and we hope to be able to help the developer community through various dev tools and implementations.

    Additional Information โž•โ€‹

    LimeChain hopes to become an important part of the Polkadot development ecosystem, supporting the network with different developer tools and integrations. AssemblyScript implementation of the SCALE Codec would be the companyโ€™s first project on Polkadot, and along with a potential AssemblyScript implementation, would drastically help our team in its onboarding with the tech stack while adding value to the developer community right away.

    Although there are other implementations of the codec, each one of them serves different purposes. Each of these projects delivered the codec in different languages. We think that having AssemblyScript implementation of the codec will benefit the development of an AssemblyScript Runtime Generation framework.

    • Are there any teams who have already contributed (financially) to the project? No
    • Have you applied for other grants so far? Not in the Polkadot ecosystem. LimeChain has received and delivered on grants from The ETH Community Fund, Maker DAO and Aeternity.

    Asylum was firstly implemented on the Solana Ignition hackathon in its initial idea. After that, the project received its first positive feedback from game developers and multiple VCs and Supercolony venture studio entered the project as a co-founder. Was held two strategical sessions, the concept was largely clarified and reworked. For now, we already have such partners as Darvinia Network and Evolution land (first DeFi game) and conversations with games such as Eizper Chain, Wind metaverse, SpaceFalcon.io. Also, we have already raised the first money from Mempool ventures and speaking with other VCs (Hillrise Group, Woodstock Fund, 500 Startups, and others).

    BD Wallet

    • Payment Address: 3FfrG9FrZXmPikEYJ9FdHPoRZ2nPjMY45W
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    The full name of BD Wallet is Black Diamond Wallet, It is a multi coin crypto wallet enables blockchain developers to build their DApps and wallets natively without having to worry about the low-level implementation details.

    Unlike other wallets, we also support centralized wallets which we call cloud wallets. Through the cloud wallet, we provide users with functions such as project rating, easy-to-operate staking, and DeFI vaults. Currently, the cloud wallets has served over 70,000 blockchain industry users.

    Cloud wallets can be considered as wallet implementations with partial centralization features, keeping their cryptocurrency for users, similar to "PayPal". Cloud wallets exist to reduce users who have no experience in using cryptocurrency wallets. They donโ€™t need to know any implementation details about the wallet, such as mnemonic words, secret keys, etc., users can directly transfer and receive encrypted currency through the account registered in our cloud wallet (the account may be a mobile phone number or email) And use other services, it is more friendly to novice users. According to our research, many users in China have this requirement. They need a simple and easy-to-use wallet and don't need to record mnemonics and secret keys by themselves.

    And we also have HD wallet to choose from to meet the needs of high-end users.

    Now, we intend to fully support the Polkadot ecosystem and contribute to the prosperity of the Polkadot ecosystem

    Overviewโ€‹

    BD Wallet which formerly known as Black Diamond Ratings, was created in January 2018, it is the first jury-type blockchain project rating in the world, with more than 500 professional reviewers, all of whom are senior practitioners in the blockchain industry. The rating range includes exchange ratings, cryptocurrency ratings. Currently, it has accumulated 17,000+ ratings, it is the largest cryptocurrency rating agency in China.

    On August 15, 2020, the company strategically merged with Bi Da Wallet and officially changed its name to Black Diamond Wallet. Black Diamond Wallet has now developed into a digital open financial one-stop solution platform integrating cryptocurrency storage, financial service, project rating and industry social contact.

    We have a professional review team to look for high-quality projects on the market and put them on the rating database. Users or project issuers can also submit project information to us, which can be included in the project database after passing the review.

    At the same time, we have a team of professional reviewers to score and rate the items in the rating library, as well as to post comments. The reviewer is a professional blockchain practitioner or cryptocurrency investor. It takes 3 years of industry experience and more than 500,000 encrypted assets to be eligible to serve as a reviewer, and provide relevant certificates to the BD team for review. Provide this rigorous screening mechanism to ensure that each reviewer is professional and to ensure fair and impartial scoring and rating of projects. Of course, the reason why reviewers will actively participate in our project review is because we will give a certain amount of HZT token rewards for high-quality reviews.

    Combining ratings and wallets is where our BDWallet is innovative. We provide users with professional project ratings. Users can view the project profile, reviewer evaluations, and reviewer ratings of related currencies through our rating library, so as to deepen usersโ€™ understanding of the project and avoid users not knowing the project. The situation makes blind investment decisions.

    And users can leave a comment under each rating, and other users can also see the message, so that users can increase their stickiness and frequency of use of the wallet. Users not only use the wallet as a tool, but also a channel for obtaining and understanding project information.

    BD Wallet will fully support the construction and development of the Polkadot ecosystem:

    1. Launch a special version of Polkadot ecosystem project Rating, in order to let more users know about Polkadot and other Polkadot related projects.
    2. Put the service of DOT Staking online to help the construction of Polkadot Node.
    3. Support DOT, KSM and other polkadot ecosystem hot projects token recharge and withdrawal.
    4. Support Polkadot ecosystem DAPP access in the future, making more users to use Polkadot Eco's DAPP easily.

    Project Detailsโ€‹

    • cloud wallet

    • hierarchical deterministic wallet

    Ecosystem Fitโ€‹

    In the current market, there are products in the same type of BD Wallet, such as imtoken, cobo wallet, math wallet.

    BD Wallet has its own unique characteristics.BD Wallet Provides the world's first jury-style rating service. It is the countryโ€™s largest rating agency and has the countryโ€™s largest rating data. BD Wallet also has a social function, which facilitates information sharing and exchange between users.

    Most of the cryptocurrency users in China do not have basic blockchain knowledge, and do not know how to participate in node construction, mortgage, voting, and nomination operations. BDWallet provides lower operating thresholds for users, compared to other Polkadot Wallet, users only need to care about the interest rate that can be obtained when participating in staking in BDWallet. We help users implement investment details.

    And BDWallet pioneered the shared staking model. When user A invites user B to participate in DOT staking, user A can obtain corresponding HZT token rewards. HZT token is the governance currency issued by our wallet. Through this incentive model, more users will spontaneously invite DOT holders to participate in DOT Staking, so that more people will participate in the ecological construction of the DOT community.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Changes summaryโ€‹

    There are some changes from the original application. The reason of the changes that some UI features that was not aligned on our roadmap and we shifted more focus on delivering public testnet and canary network.

    Here are summary of changes

    • Remove 3D map and continuum UI out of the application scope.
    • Adjusted Continuum Governance Protocol.
    • Added Buying Continuum Spot with fixed cost.
    • Added Sign to support NFT.
    • Added Multi tokens local marketplace.
    • Added Benchmarking.
    • Adjusted the cost.
    • Adjust the FTE.

    Summaryโ€‹

    Since completing the first milestone for Bit.Country, we have developed multiple proof of concepts for newer features such as Continuum (the map of bit countries), the marketplaces and NFT minting.

    We have also developed the virtual world further, implementing collaborative building, material packs, persistance of changes and general tweaks to the UI and experience. Currently undergoing basic user testing and demoing to interested parties.

    Other work has included changes to the design and layout of the DApp; improved sharing experience for posts and content created on the bit country timelines; migration to improve scalability.

    The team has also been applying for a number of accelerators, and receiving attention/interest from multiple VCs, funds and KOLs. Currently, oversubscribed so negotiating with them to determine the initial round allocations. The team has recently been accepted into the Berkeley Blockchain Xcelerator cohort of 2021. Currently in talks with VCs, funds and KOLs who have reach to over 40 million fans. If you are interested to hear more about our current progress, please email us at hi@bit.country

    Considerationsโ€‹

    We have been investigating the possibility of using decentralized storage for more aspects of bit country content and storage needs, a basic proof of concept is being worked on.

    The team has been reconsidering the block planner for a bit country and its related block theme feature as part of milestone 1. We are now looking at separating the logic to enable a smoother experience between users who wish to use a predesigned template or build from scratch.

    Integrating Polkadot.js with Blackprint

    • Team Name: Blackprint
    • Payment Address: 0xE8b5923f891C5d42eBF9f385DDDFA4a8A74cb9AA (DAI)
    • Level: 1

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Note: "node" does refer to Blackprint's node, not blockchain's node

    Blackprint is a visual programming tool that can help developers interact with libraries by simply connecting nodes in realtime without the need to code. Developers themselves will need to use Blackprint Engine and load required modules to execute exported JSON of node, cable connections, and embedded data.

    Blackprint hopefully can help the development of Metaverse, frontend development, as well as automation such as bots that connect to multiple blockchains. Blackprint itself is planning to expand to support several programming languages such as JavaScript, PHP, Golang, and Python. But this proposal is currently only for JavaScript as Blackprint is still trying to improve.

    Project Detailsโ€‹

    Technology stackโ€‹

    • JavaScript (Browser & Node.js)
    • Polkadot.js's library
    • Blackprint does have 2 main component:
      • Engine: Designed for managing data flow between nodes and can be run on Browser/Node.js/Deno
      • Sketch: Can be used for creating node editor and modify node connections
    • Blackprint Editor: An IDE that combine the sketch and the engine and provide another tools on the GUI to make the development more easier

    Architectureโ€‹

    Below is the current architecture on how Blackprint works. Architecture

    Note: engine does refer to Blackprint Engine, and not JavaScript's V8 engine

    Blackprint Sketch is a minimal node editor where the user can interact (move, click, manage cable connection) with the nodes and it's depends on Blackprint Engine. Modifying node/cable from the sketch in real time will change engine's behavior to manage data flow between nodes.

    The data changes from the engine will trigger JS Module (the orange colored shape) for interact with Polkadot.js's library. JS Module is an additional module/addons for Blackprint, when it's loaded it will registering node for sketch and engine. Polkadot.js's library then will handle the connection between parachain and the current environment (Browser/Node.js).

    Minimum Viable Product (MVP)โ€‹

    Please scroll down again if you prefer to see some video example instead

    MVP

    The screenshot above is taken from Blackprint Editor that using nodes from this MVP module. The module itself is already usable for browser, but the module haven't been published on NPM. Because currently it's still in development, I have put a few example to try it on the repository.

    Some explanation for the screenshot above

    The process is begin from WebSocket connection, after it get connected to the network the Provider and API port will have an value and will trigger the other port like Blocks Event and Transfer node. Blocks Event will then subscribing for new block event, and will update it's UI automatically for visualisation. When the Transfer node has value for API, Address, Value port, it will create a unsigned transaction into Txn port. The filled Txn port will send the value to another node like Txn Payment Info and Send Transaction node. The Send Transaction will need to be triggered manually by calling Submit port and also the Provider port need to be connected with port from WebSocket. The Browser Wallet node is required for asking permission for accessing Polkadot.js extension, and the Signer node can be used after the permission was granted.

    Each port has it's own type data, the details can be seen by hovering the port with a cursor.

    Example: Listening to new blocksโ€‹

    https://user-images.githubusercontent.com/11073373/148692354-3a9ffad4-ef5e-4fa5-9bdb-d8d07b5b59e9.mp4

    With the current MVP, we can listen to new blocks/head by connecting to the parachain via WebSocket. By using Ctrl + Right Click on the API port, we can get a list of suggested node. The Blocks Event then will use the API to subscribe to chain_subscribeNewHeads with help of Polkadot.js's library. The output value (Number port) of Blocks Event will be updated everytime the block number has changed, the New port is supposed for call a function/trigger. At the end of video, I also opened the Chain info explorer to see if the number was match with the current network state.

    Example: Retrieve transaction fee/infoโ€‹

    https://user-images.githubusercontent.com/11073373/148692778-bdf3e096-64d3-43e4-ac7c-38c7785de8cd.mp4

    From the video, I'm creating a Transfer node that can be used for creating unsigned transaction. It will only executed after all required port is filled. I'm then trying to retrieve the payment info for the Txn and sign it by using dummy signer. The Txn Payment Info node then will update it's value for the output port (Info). The output is an Object.

    Limitation of the project:โ€‹

    • Blackprint doesn't generate JS script/code dynamically and can only operate if the custom node is already registered with Blackprint Engine from an external/loaded module.
    • Blackprint Sketch can export the sketch into JSON, and the users can import it to Blackprint Engine for Browser/Node.js. The engine itself will need the JS module to interact with Polkadot.js's library.

    Ecosystem Fitโ€‹

    Blackprint can be used as a playground for experimenting with Polkadot.js library. Like creating their own program without writing code for doing transaction, signing/encrypting data. But just by simply load the module and begin connecting nodes interactively. For production use, they can easily export to JSON and import it on their target environment (browser/Node.js).

    Hopefully users with no knowledge about how create transaction into blockchain may find this helpful for getting started by learning the concept first. It can also help dApp and metaverse developers.

    In the future of metaverse, I hope it can also help users who don't have programming background can easily program it's own logic with the available nodes realtime inside the game/world.

    For example like non-programmer who want to:

    1. Collaboratively creating in-game ATM that can connect to different blockchain via RPC
    2. Trigger transaction when interacting with in-game shop and able to see how the data flow works with Blackprint

    The above is just my vision for the future. I haven't created any prototype of it yet, but it may be possible if some Metaverse project adopted Blackprint for its project.

    Development Status ๐Ÿ“–โ€‹

    Note: Polkadot.js nodes for Blackprint is the JS module I mentioned on Architecture section

    At the time of writing this proposal. Currently Blackprint is already usable, but it's still unstable and being optimized for better performance and design. It's already trying to follow semantic versioning and may only introduce breaking changes on increment of v0.*.0.

    Below is the repository about current development.

    Currently the MVP can be run on browsers. The support for Node.js is still work in progress and may be delivered on Milestone 3. The current MVP may already contain nodes that will be delivered for Milestone 1 and Milestone 2, I'm still preparing to create the unit test and some example before I deliver it.

    Future Plansโ€‹

    • Add Blackprint node for some feature from Substrate Metadata
    • Finishing Blackprint's roadmap
    • Build more nodes for Blackprint to make it more suitable as a development tools or IDE
    • Build a community server on Discord to grow from individual developer into a team
    • Because Blackprint is also still unstable and polkadot.js library may also have some changes on the future, I'm willing to update and maintain the the delivered nodes.

    At the time writting -- when having many nodes and cable, users may find Blackprint looks complicated because currently they can't arrange the cable. Because of that, on the future I'm going to improve the UI/UX for managing cable.

    Additional Information โž•โ€‹

    How did you hear about the Grants Program?
    I heard about the Grants Program from Web3 Foundation's website when doing research about Polkadot's Parachain Rollout.

    Additional information that I think may relevant to this application:

    • I'm planning to implement custom node for ethers.js as I already know how to use the library, but currently I more motivated to Polkadot because of this Grants Program.
    • When doing research about Arweave, I also created custom nodes for Arweave. It's already usable on Blackprint Editor and can be imported on Blackprint Editor together with other nodes. But currently it has no tests or documentation.

    Project Overviewโ€‹

    Overviewโ€‹

    Blockchainia delivers the benefits of digital ownership straight to gamers fingertips. Our infrastructure will enable developers to create games for gamers that decide to take ownership of their digital achievements. The Blockchainia library of pallets enables affordable pay-to-play games that forever immortalize gamings greatest moments on-chain. As an eventual competitive gaming metaverse, Blockchaina's ecosystem includes a community hosted online multiplayer infrastructure including a game engine that will interact directly with our gamechain for user moderated online gaming.

    Our Milestone 1 open-source pallets will enable:

    • a web based online multiplayer PvPvE first-person shooter (Player vs Player vs Environment (AI) Enemy)
    • the engine that drives interactions between server and client
    • a leader board that aggregates in-game earned on-chain statistics by week, month, and year.
    • air dropped NFTs earned by completing in game tasks and leader board achievements
    • environment enemies spawned from on-chain NFT assets that funnel spoils back to its owner's wallet
    • a player prompt to create a wallet upon exit or completion
    • community driven DAO that manages the online server infrastructure

    Future milestones will include updates to:

    • an evolving and expanding list of features through our open-source substrate pallet library
    • Two games that use our pallets to share in game items between them
      • an evolving JRPG that explains our gamechains "lore"
      • an evolving arcade style online multiplayer PvPvE

    While there are other gaming projects in the ecosystem, ours differs in various ways. First, we will break the stigma gamers associate with NFTs through a fun JRPG. Non-playable character "blocks" will explain their purpose as well as the metaverse they inhabit in their on-chain existence. However, not all is as it seems in the troubled world of Blockchainia. Players will make their way through seasonally released updates to uncover the deep lore, rescue these NPC blocks, and discover the fun that digital ownership brings to the future of gaming. The items and experience earned in this JRPG will be stored on-chain to the users wallet and available in our arcade PvPvE. We have acquired the URL Blockchainia.gg as the landing page for both of these games.

    Other similar projects in the ecosystem are Ajuna and Bajun. We plan to build off of Ajuna's Layer 1 solution, and expand on their layer 2 and 3 solutions with our own side chain.

    We differ in that we have the behavioral and marketing background to rapidly onboard users, as well as a product that can create a niche for itself in currently over-saturated market. Mark Zuckerberg tried and failed to create a metaverse with endless resources because he fails to realize the human utility of the technology of his time. We have the right team and the right vision to bring the metaverse to fruition, through a fair and economical value proposition that helped NBA Jam (Midway Games) earn 1 billion dollars to Jurassic Park's (Amblin Entertainment) 395 million in 1993, in quarters (.25USD). We believe we can minimize the cost to consumers by operating our sidechain at the lowest cost possible while allowing a DAO driven public server community to earn a reasonable fee for hosting the online multiplayer infrastructure of the games in our ecosystem. This fee will eventually approach a real market value which will add value to the various fungible tokens used throughout the ecosystem.

    We will create free-to-use Unity assets that compliment our tech stack to allow independent developers to duplicate our model and optionally distribute their games via our distribution architecture or use our reputation based, community moderated online-multiplayer infrastructure.

    Ecosystem Fitโ€‹

    Our target audience includes game developers and gamers. Our initial target will focus on indie gamers who would like to remove the overhead realized by releasing their games through traditional distribution channels. Using our infrastructure, developers can release their game free-to-try. Developers will release an NFT collection of playable characters at the same time which grants players full access to decentralized features that will change the way gamers think about the accomplishments and items they earn in game.

    To do this, we will create or modify many existing parts of the Polkadot ecosystem, including browser wallets, chain browsers, and our own parachain optimized for handling real-time game events as on-chain transactions. Our project will have a touch point on almost all levels of the Polkadot stack.

    In future updates, we plan to develop a decentralized means of distribution that allows game developers to release directly to consumers. Our DAO-driven community will engage with developers and provide valuable feedback on desired features, games, and the direction of Blockchainia as a whole.

    Development Statusโ€‹

    We have begun development on a server authoritative online multiplayer game engine that allows for a dedicated server to interact with a game client and perform the prediction and interpolation to reduce perceived latency enough to allow for a seamless game play experience. We will be adding these repositories below over the next few weeks. When the game is in its first "playable" state we will begin experimentation with Ajuna's service layer for our on chain interactions, building on top of their service layer to implement our custom pallets and interact with a custom game chain.

    0a.LicenseApache 2.0 / GPLv3 / MIT / Unlicense
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works. This project also includes creating documentation to will allow our community to test and involve themselves in our multiplayer gaming infrastructure. We hope to receive and respond to feedback on this community documentation in Milestone 2.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. Unit tests will be written for relevant game server functionality. Unit tests will be written for the DeathToll pallet. In each guide (in each project's Github repo), we will describe how to run these tests. Manual integration testing will be through in-game functionality (i.e, Given an enemy is eliminated on server, the proper state functions are executed on chain, and the leader board updates through the in-game chain browser)
    0d.DockerWe will provide Dockerfiles that can be used to run and test all the functionality delivered with this milestone. This will include a deployable "Full Node" that encases both a game server and substrate node. These will interact with our game client and substrate parachain respectively. A successful MVP will allow a game client to register events on the game server (Server-Authoritative model), which is then written to the parachain ledger. Upon completion of the initial game "level", an "accolade" NFT will be deposited via ink! smart contract to the wallet that completed the required in-game tasks.
    1.Substrate module: Game Engine EventsThe Game Events Substrate module will contain functionality for asynchronously administering the the match between the game server and blockchain node. It is likely that we will break this into multiple pallets, one for core gaming functionality, and one specific to the needs of the DeathToll game-type. The initial pallet features include functionality to create, administer, and write the outcome of a match to the chain, updating the wallets of all players with their earned experience (which is key to the economy of Blockchainia). This module will work on top of Ajuna's service layer to aggregate and marshall game state information relevant to tracked leader board statistics and write to chain. These events will include in game events like player eliminations, deaths, attacks attempted/missed, wins, and other in-game achievements in our continuously expanding list of features. Eventually, this list of configurable features will allow a server owner to run game types similar to those seen in other first-person shooters, like death match, hostage rescue, and capture the flag. The configurable nature of our servers will allow our community to self-explore and find a region of our community that suits their personal play style and temperament.
    2.Unity Game Engine and Configurable Server/ClientWe will embed our substrate based chain interactions into our game engine. While the game client and server communicate to drive game play, the game server will also publish certain events to the game chain via Ajuna's Service layer. Each of these processes will initially be deployable via docker container. The game server architecture will operate from a community driven DAO implemented with existing society and membership pallets available in the Substrate store. The value in the deliverable for the game/server lies in its online multiplayer architecture. We will use a server authoritative model embedded with our web3 backend via the substrate modules created in deliverable 1. We will layer these on top and alongside services provided by Ajuna to interact with our game chain. To start a match, the server must request that a "match" be created on chain via ink! smart contract after collecting a nominal fee from connected players. The server will also request the information necessary to spawn environment enemies in the game map from owned NFTs on chain at random. Lastly, players will spawn and game play will begin. In game events, such as when a player eliminates another player or environment enemy, will be written to chain. These streams of game commands which make up the packets sent by the client to the server are used to compensate for latency with methods like prediction and interpolation. Our engine will be similar to that used in Quake (id Software, Microsoft) and Half-Life (Valve, Sierra Studios), using various methods to compensate for latency and ensure a pleasant user experience, the key difference being that interactions leading to specific events will be logged to the chain. With this advancement in technology, Blockchainia will redefine how streamers and creators interact with their followers, and re-imagine how games can interact with a player. Gamings greatest moments will be immortalized on chain, allowing players the chance to engrave their accomplishments on web3's Stanley Cup, our eternal sliding time window leader board. Milestone 1 begins with a simple MVP to onboard users and test our engine before expanding on our functionality and appealing to a broader market. We will receive community feedback on how to fairly and equitably handle situations including server crashes and moderation of hacking and toxicity. This will lead to a code of conduct in deliverable 2 as we expand our features to include a map and item builder, as well as a strong in-game economy. We will also expand on a configurable set of features that affords future web3 game developers to configure our engine for their own games and expand on its features.
    3.Unity AssetsBesides the NFT playable characters released in our games collections, all assets created by our team will be released free to use by other developers who would like to use our ecosystem to create their own games and mods. These will include wall and floor textures, doors, environment enemies, and other sprites used throughout our games.

    Future Plansโ€‹

    NumberDeliverableSpecification
    1.Oculus VR PortWe plan to port our PvPvE and JRPG to Oculus VR. This will be used to expand into a metaverse of gamers, lead by a community of streamers and industry leaders who moderate their servers and influence the direction of our development team through their position in our community DAO.
    2.Front End ExpansionOur initial browser will be embedded into the game client itself. We plan to expand this to an iOS and Android apps for viewing leader boards, displaying accomplishments, and trading collectibles.
    3.Community ExpansionUsers who are invited to the DAO will be encouraged to run their own reputable server/node to grow their community and earn money from the pay-to-play architecture. Owners will create a hierarchy of moderators called "admins" that will ensure fair, fun, and competitive game play throughout our ecosystem. Owners/Servers who do not fulfill their commitments to the greater community will have their influence slashed.
    4.Automate integration testingAutomated integration tests for all game server/blockchain interactions.
    5.Substrate module: DeathToll Game Events ExpansionWe will add new features to the DeathToll Game Events Substrate module in seasonal updates. The features added will be driven in part by the community that plays the game, in the form of the DAO created during Milestone

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Bounce is a decentralized auction platform, incorporating liquidity mining, decentralized governance and staking mechanisms. The first principle of Bounce is scarcity of resources, which creates a competitive swap environment.

    The idea of โ€œswapโ€ originated from Uniswap, where infinite liquidity is provided for participants. While this is a great and concept, Bounce focusses on the opposite scenario instead.

    Bounce provides a competitive environment, for a limited supply of tokens or other assets like NFT's. The assets can be auctioned off in various ways, such as:

    • Token sales: Various types of auctions where a limited amount of tokens are auctioned off with different auction principles and time limits, such as fixed price (fixed swap auction), decreasing price (Dutch auction) or hidden price (sealed-bid auction)

    • NFT auctions: NFT's are auctioned off with similar auction principles as token sales. However, there is usually a lower number of NFT's (or only a unique piece) for sale.

    We will run Bounce chain as standalone chain first, then join in Kusama/Polkadot network when parachain mechanism is ready.

    Project Overviewโ€‹

    BrightTreasury logo

    BrightTreasury - a web app for handling the network treasury module.

    Overviewโ€‹

    The aim of the BrightTreasury project is to create a standalone web application along with a PWA representation that would allow performing basic actions on the Treasury module of Polkadot and Kusama Substrate networks (with a potential to support any Substrate-based network with Treasury module). It would allow a more intuitive and lightweight flow of submitting proposals as well as an overview of the Treasury related actions.

    Our focus will be on the regular userโ€™s actions rather than the council perspective for this first release. We want to attract more professionals who could contribute to the community with their ideas and skills but at the same time may not be as fluent in blockchain customs and terminology.

    Based on the discussions with the Substrate networksโ€™ users and council members as well as analysis of the comments under Polkadot and Kusama proposal submissions, we identified areas that caused most issues in the Treasury funding process from the userโ€™s perspective. The main needs that were brought up were:

    • more intuitive proposal submission flow, with clearer indication of a proposal idea being subject to the community discussion, before submitting to blockchain and committing with bond funds
    • one place for following the submitted proposals, their status and the results of motions
    • a unified discussion forum to leave comments about submitted proposals as well as their draft versions (ideas)
    • implementation of the new bounties funding mechanism

    Following these needs, we propose a solution that will benefit the Substrate chains communities.

    Project Detailsโ€‹

    The application will have the proposal lifecycle as its main focus - starting from a more approachable proposal definition, clearly stated two phases of the submission (an Idea for preliminary discussion and the formal Proposal after blockchain confirmation) followed by an intuitive overview of the submitted proposals and their state.

    Technology stack: NestJS and React

    In addition to the currently available functionality within the Treasury module, we plan to introduce supplementary features that can benefit the user experience.

    What is more, as we understand that visual aspects are crucial when talking about user experience, we have prepared the clickable designs that illustrate the main flow we wish to implement. Please find it under the following link: https://xd.adobe.com/view/0bb66d6e-5797-40bc-aa29-c6f71131f402-5ee5/

    Ecosystem Fitโ€‹

    Currently, the Treasury module is a part of the general network management tool. We plan to separate it and develop an independent service, with a more streamlined and intuitive flow and presentation. Such a platform would be more approachable for the users from outside of the blockchain community and have a potential for simpler promotion of the Treasury funded actions.

    Main distinguishing features:

    • a more intuitive, two-step flow for submitting proposals (Idea -> Proposal)
    • in-app module for more detailed proposal descriptions (like adding milestones) connected with proposal related discussion and - reporting progress on approved proposals
    • clear overview of the submitted proposals matched with derived motions and their results
    • historical overview of the past spending periodsโ€™ proposals that were submitted using the app

    Development Roadmapโ€‹

    The development of the specified user stories will be broken into 3 milestones, each taking 1 month to complete.

    Definition of Done for each user story:

    • Unit tests passed
    • Code has been reviewed by peer
    • Acceptance criteria were met
    • Internal QA has been performed
    • Documentation has been written
    • Screens are responsive and prepared both for desktop and PWA (mobile and tablet)
    • Browser compatibility
      • Chrome from 70 upwards
        • ย ย 
      • Safari from 12 upwards
      • Firefox from 57 upwards
        • ย ย ย 
      • Edge from 42 upwards

    At the end of each milestone:

    • The user stories listed for the given milestone have been implemented both on frontend and backed and the DoD criteria were met, allowing the user to perform the defined actions
    • The functionality has been deployed to stage environment, accessible for testing purposes

    Overviewโ€‹

    • Total Estimated Duration: 3 months
    • Full-time equivalent (FTE): 1
    • Total Costs: 28 500 DAI

    Milestone 1 โ€” Idea creating & Proposal submission & in-app loginsโ€‹

    • Estimated Duration: 1 month
    • FTE: 1.1 FTE
    • Costs: 10 450 DAI

    The main goal of this milestone is to implement the core flow of the app, that is the Proposal lifecycle. As a result the user will be able to create an Idea, add all the necessary details, create Milestones for an Idea, make it public and decide to submit the Idea to the blockchain, turning it into a formal Proposal. The status of the Proposal will be then updated based on the data returning from the API. To perform these actions a user will need to be logged in, however browsing through ideas and proposals will be available to everyone.

    Milestone 2 โ€” discussions panel & treasury overview & multiple networksโ€‹

    • Estimated Duration: 1 month
    • FTE: 0.9 FTE
    • Costs: 8 550 DAI

    The goal of this milestone is to add more features to the ideas and proposals handling. The ideas as well as proposals will have the discussion functionality added and it will be possible to add them to multiple networks as well, as the representation of multiple blockchain networks feature will also be implemented at this stage. What is more, an overview of the treasury statistics will be presented for each network respectively.

    Milestone 3 โ€” Bounties & in-app historyโ€‹

    • Estimated Duration: 1 month
    • FTE: 1 FTE
    • Costs: 9 500 DAI

    The main goal of this milestone is implementation of the bounties mechanism. Users will be able to add and browse through bounties, votings for their curators and check the current status. The curators will be able to accept (or reject) their nominations and manage the bountyโ€™s status. Additionally, in this milestone we plan to add a basic integration with Polkassembly. It will be possible to see the description of a proposal/bounty published on Polkassembly. We will also include the history feature based on the data from Polkassembly, which would allow users to browse through closed proposals and bounties, in addition to in-app ideas. What is more, we plan to prepare the Milestone 1 and 2 features for production environment and deploy them, so they would be already fully functional to the Polkadot and Kusama proposals.

    Community engagementโ€‹

    It is our priority to make the BrightTreasury app a living part of the communityโ€™s life and as such, we plan on several informational activities such as:

    • We want to ask Polkadot blog team to kindly agree on us publishing two articles on their blog (https://polkadot.network/blog/): one at the beginning of the project, second as a tutorial at the end of the project
    • We will also submit an article to Medium at the end of the project, presenting the application and its potential contribution
    • Two blog posts on our Bright Inventions blog https://brightinventions.pl/blog

    Future Plansโ€‹

    In future, we plan to include a Tips mechanism as well, with a similar intuitive approach.

    What is more, we would like to further integrate with Polkassembly to allow a two-way communication. We plan to display proposals and bounties created using BirghtTreasury (along with their details and discussions) in Polkassembly as well and update any changes in both services.

    • Team Name: Matthew Darnell (Individual)
    • Payment Address: 15ssDeS9peN9a3rDwFrV19YJ8oRffmphaE (BTC)
    • Level: 1
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • cScale is a SCALE codec implementation in C
    • Currently there does not seem to be a working standalone implementation of this serialization codec in C
    • A SCALE implementation would allow for the development of more desktop applications communicating with Substrate nodes
    • I am developing this because I am interested in creating a simple and secure desktop Substrate wallet
    • I already have a generally working product that I would also like to improve as I get suggestions

    Project Detailsโ€‹

    • Technology stack will be a simple C library, mostly in C99 with a few uses of C11 _Generic. One dependency currently will be included which is an open sourced, single file, pure-header utf8 implementation useful for SCALE string encoding.
    • Makefile is included but can do simple CMakeLists.txt if preferred
    • Supported Data Types will be:
      • Fixed Width Integers
      • Compact/General Integers
      • Booleans
      • Options
      • Vectors (and Strings)
      • Enumerations
      • Tuples
      • User-Defined Data Structures
    • Some limitations and caveats:
      • C does not support uint128_t types. Possible options are to introduce a 3rd party dependency or consume u128 values encoded as char* strings. GCC does provide a uint128_t extension but I'm not sure how universal this is and C does not support sufficiently long literal int values. Currently I am able to encode from a hex-represented u128 but could consume decimal represented char* strings if required.
      • Enumerations are tricky to implement as they are user-defined. I am able to construct a struct which generates a custom enum type by consuming an array of strings of different types, e.g. [Int, Bool], but I am not sure how to make this very clean for the user.
      • A lack of templating and type inference makes encoding/decoding user-defined struct values a little difficult. I am able to achieve this by defining a custom struct which contains a serialize as well as deserialize function pointer. The user will be able to include this struct in his data structure and assign his own custom function. This works fine, but again, it is a little more in depth for the end user than ideal.
      • With each of these, I would love feedback from others on how to improve the library!

    Ecosystem Fitโ€‹

    • The target audience are Desktop C/C++ developers who would like to be able to encode and decode Substrate API data
    • Similar Projects
      • Kagome (C++ and not intended for standalone library use)
      • FinoaBanking substrate-c-tool (Has not been updated for over a year and is in unknown state of completion as far as I can tell)

    Currently have a basic working implementation. Generating a testing app, a basic cli app, and a statically linked library.

    Some examples:

    Fixed Intโ€‹

    scale_fixed_int fixed = { 0 };
    encode_int_to_fixed_int_scale(&fixed, (uint16_t)42);
    uint8_t serialized[64] = { 0 };
    size_t serialized_len = 0;
    serialize_fixed_int(serialized, &serialized_len, &fixed);

    uint16_t output = 0;
    decode_scale_fixed_int((void*)&output, &fixed);

    for(int i=0; i < serialized_len; i++) printf("%02X", serialized[i]);
    printf(" --- %u\n", output);

    Prints:

    2A00 --- 42

    Compact Intโ€‹

     scale_compact_int compact = { 0 };
      encode_compact(&compact, (uint32_t)69);
      uint8_t serialized[64] = { 0 };
      size_t serialized_len = 0;
      char *output = decode_compact_to_hex(&compact);
      serialize_compact_int(serialized, &serialized_len, &compact);
      uint32_t decoded = strtoul(output, NULL, 16);
      printf("SCALE=<");
      for(int i=0; i < serialized_len; i++) printf("%02X", serialized[i]);
      printf("> --- Hex=<%s> --- Decoded=<%u>\n", output, decoded);
      free(output);

    Prints:

    Future Plansโ€‹

    • I am writing this library to use in my own personal desktop wallet application
    • I see a real need for it to allow the Substrate community to grow and I hope it makes it on the official list of Scale Implementations
    • Long term I would be interested in improving this library to keep current with a possibly-evolving SCALE standard as well as getting help from other C devs making pull requests, which would be most welcome.

    • Team Name: Canyon Labs
    • Payment Address: 0x009643f61C7cbc91404aE77Fe65542D098B822d1 (DAI)

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Canyon is designed to be a permanent storage network built on Substrate, which records the hashes of files on-chain and stores the files off-chain. By blending PoS and a probabilistic proof-of-storage scheme inspired by Arweave, Canyon greatly reduces the barriers to entry for miners, who are incentivized to store as much data as possible for the rewards. Another focus of canyon is also to build a truly useful data sharing system, providing the high availability of data access in the protocol level.

    Project Detailsโ€‹

    This grant mainly concentrates on the consensus part of canyon network, specifically the PoA consensus will be implemented. Aside from the core consensus algorithm, some indispensable basic components/tools will be built at the same time. Refer to the consensus section of white paper for more information. We'll also keep updating the technical details in the paper when necessary once more progress is made.

    Ecosystem Fitโ€‹

    There is no doubt that the infrastructure, providing a secure, highly available, low-cost, and easy-to-use decentralized data access service, will be an essential part of Web3.0 applications. Canyon network is created in such a background and tries to mitigate the known problems in the existing decentralized platforms, with a principle of lightweight storage consensus and highly usable protocol level data retrieval mechanism in mind.

    1.Node: cc-rpcWe will create a crate that will provides two RPCs: permastore_submit and permastore_retrieve for storing the data(<=10MiB) respectively
    2.Node: cc-databaseWe will create a crate that will provide the feature of persistent transaction data storage on the top of offchain storage.
    3.Node: cc-consensus-poaWe will create a crate that will implement the core algorithm of PoA illustrated in the white paper. This crate will also implement the function of inherent data provider to inject a DigestItem::Seal entry providing the proof of access into the block header. We will verify the DigesteItem::Seal(PoA) item in the block header by wrapping a poa import queue component into the current babe block import.
    4.Node: pallet-poaWe will create a pallet that will implement ProvideInherent to make use of the inherent data created in step 3, create an inherent extrinsic update_storage_capacity recording the storage capacity of block author on-chain.
    5.Rust CLI: submitWe will extend canyon-cli by adding two new commands: submit to store the data from CLI which calls permastore_submit internally, submit-and-store will firstly call submit and send the extrinsic permastore::store to actually store the data onto the network.

    cc-rpc RPCs:

    • permastore_submit

      • fn submit(value: Bytes) -> Result<H256>
      • user can send arbitray data bytes(<=10MiB) to the node, the chunk root will be returned once stored successfully.

    • permastore_retrieve

      • fn retrieve(key: Bytes) -> Result<Option<Bytes>>
      • user can retrieve the data(<=10MiB) directly using this PRC, the key is the chunk root of the data.

    Future Plansโ€‹

    The short term plans:

    • Implement the pricing strategy for the store transaction in the context of paying once for the perpetual storage.
    • Support uploading/retrieving data chunks for large files(>10MiB).
    • Implement transaction data sync between the multiple nodes.
    • A comprehensive design for Staking system on the top of NPOS, taking the factor of validator that also behaves a storage service provider into account.
    • Improve and audit the code to make it production-ready.
    • Build client tools for storing data onto the network easily, especially the web UI.
    • Build a network data explorer that shows the distribution of data in network nodes.

    The long term plans:

    • Do more researches and develop a more effective data sharing mechanism, rendering canyon network a highly useable data retrieval platform.
    • Foster more web3.0 applications using the decentralized storage infrastructure provided by canyon network.

    Project Overview ๐Ÿ“„โ€‹

    This is a follow-up grant to keep building on top of this Go Client implementation. In the past we had two grants.

    The original grant through w3f:

    And a maintenance Grant through Polkadot Treasury:

    Overviewโ€‹

    Initially Go-Substrate-RPC (GSRPC for short) was designed under the premise of being a low-level, static and strongly typed library, where all the type resolution happen at compilation time.

    This approach allowed almost full flexibility to developers to build their own types and events depending on the target chain/s they were connecting to.

    On the other hand, since the types are statically defined, this didnโ€™t leave room to, gracefully, deal with parsing errors when a type (defined on the chain runtime) is not defined in the GSRPC client.

    Project Detailsโ€‹

    The problemโ€‹

    For a hypothetical RuntimeA, give TypeA:

    type TypeA struct {
        AttrA String
        AttrB int
    }

    and EventA, that uses TypeA:

    type EventA struct {
        Data TypeA
    }

    The GSRPC instance should define TypeA to be able to decode EventA. If the client is defined as such, then there will be no problem parsing it.

    Now lets presume that a RuntimeUpgrade is executed and now the target chain is at version B -> RuntimeB. In this runtime ugprade attribute AttrB of struct TypeA has changed to String:

    type TypeA struct {
        AttrA String
        AttrB String
    }

    Then when the GSRPC client is trying to parse the event, it will fail while trying to decode the scale encoded value into the EventA struct since the type that is expecting for AttrB is an int but a string has been provided.

    This issue gets more critical when we are talking about processes, like bridges, that need to successfully parse every event in a block looking for a relevant event to their business logic. If due to the above reason, an event can't be parsed then the bridge relayer cannot ensure that a relevant event was or wasn't in that block. Therefore the only options are to skip that block (hoping that there was no relevant event within) or wait until the client is updated to continue parsing blocks, which disrupts the bridge operations.

    Solutionโ€‹

    With the inclusion of Substrate Metadata 14, we now have a definition of all the types included in a specific runtime.

    This means that at bootstrap time (and upon other certain situations) GSRPC can build a registry of types based on the data provided by the target chain metadata.

    Load types into registry from Metadataโ€‹
    Example of Metadata 14 type structure for a Balances.Transfer Eventโ€‹

    Pallet Name and associated type variants index

    Pallets.5.Name = "Balances"
    Pallets.5.Events.Type.UCompact = 28 // Events list type index

    For event Balances.Transfer with index 2 in the variants list there are 3 fields, from, to & amount.

    Lookup.Types.27.Variant.Variants.2.Name = "Transfer"
    Lookup.Types.27.Variant.Variants.2.Fields.0.Name = "from"
    Lookup.Types.27.Variant.Variants.2.Fields.0.TypeName = "T::AccountId" // Some types do not have an index reference
    Lookup.Types.27.Variant.Variants.2.Fields.1.Name = "to"
    Lookup.Types.27.Variant.Variants.2.Fields.1.TypeName = "T::AccountId"
    Lookup.Types.27.Variant.Variants.2.Fields.2.Name = "amount"
    Lookup.Types.27.Variant.Variants.2.Fields.2.TypeName = "T::Balance"
    Lookup.Types.27.Variant.Variants.2.Fields.2.Type.UCompact = 6

    from & to have type T::AccountId which is a Runtime Primitive, and potentially can have different implementations depending on the runtime connected to. In most of the cases, it would be an AccountId32, but that can be changed.

    amount has a type reference to index 6 so we can navigate to that type:

    Lookup.Types.6.Type.Def.Primitive = 7 (Si0TypeDefPrimitive)

    And that tells us that is refering to Rust Primitive number 7, so according to the primitive list (found in polkadotjs/api) for type Si0TypeDefPrimitive:

    0:  readonly isBool: boolean;
    1:  readonly isChar: boolean;
    2:  readonly isStr: boolean;
    3:  readonly isU8: boolean;
    4:  readonly isU16: boolean;
    5:  readonly isU32: boolean;
    6:  readonly isU64: boolean;
    7:  readonly isU128: boolean;
    8:  readonly isU256: boolean;
    9:  readonly isI8: boolean;
    10: readonly isI16: boolean;
    11: readonly isI32: boolean;
    12: readonly isI64: boolean;
    13: readonly isI128: boolean;
    14: readonly isI256: boolean;

    The underlying type is U128

    Challenges to solve:

    New generic type registry encoder/decoderโ€‹

    The next step is to build a generic encoder/decoder that works for all discovered types based on underlaying primitive types.

    In theory, once the types are loaded, and we built generic encoders for basic primitive types, we should be able to encode & decode all types and events.

    Challenges to solve:

    • Build generic encoder/decoder for any type loaded in the registry
    • Support custom encoder/decoder for irregular struct serialization and deserialization

    Project Overview ๐Ÿ“„โ€‹

    Problem Statementโ€‹

    The ongoing discussion about automated market makers (AMMs) in the Statemint roadmap is mainly focused on improving the user and custodian experience by allowing small atomic swaps natively and making Statemint a central hub for asset deposits. This addresses important pain points by enabling transaction fees to be paid in non-native tokens and facilitating interaction with the entire asset variety of the ecosystem without requiring to run custom nodes or infrastructure.

    However, we believe that one aspect has been overlooked: the slow swaps of large volumes, which can be easily front-run or sandwiched. This is particularly relevant in the context of trades proposed through governance for use cases such as

    1. Paying out treasury grants, bounties or even salaries in less volatile currencies (ie. stablecoins).
    2. Enabling parachains to build a DOT reserve which can be used to acquire a parachain lease, pay XCM fees, or increase availability cores during times of high demand (once supported).
    3. Governance deciding to invest part of the treasury into a token to diversify their treasury

    What we need is the opposite of what a traditional AMM provides: atomic swaps with immediate execution, even in relatively illiquid assets. A governance vote is unable to time the market and is highly predictable. Therefore, executing such a transaction as a market order on an AMM is problematic, as it will be guaranteed to be front-run. A better solution is to "dollar-cost-average" over a long period of time making it harder for price manipulation to affect the purchase.

    Solutionโ€‹

    At Centrifuge, we have researched distinct approaches of how to achieve hard-to-front-run slower transactions. In our opinion, the most elegant solution is TWAMM (Time Weighted Automated Market Maker. We are of the firm conviction that the implementation of this model represents the most efficacious approach for executing token swaps in the context of slower and passive procedures, such as governance.

    Time Weighted Average Market Makerโ€‹

    The TWAMM protocol represents a sophisticated advancement of the conventional constant product (Uniswap-v2 style) automated market maker (AMM) framework. It introduces a novel feature wherein users can split their orders into infinitely small fractions and execute them at each block interval. This feature addresses a significant shortcoming of traditional AMMs that encounter severe slippage issues when processing sizable orders, leaving them vulnerable to front-running tactics.

    Furthermore, the inherent risk associated with executing transactions within a single block is nullified by the TWAMM protocol. By segmenting orders into hundreds of small units spread over a prolonged time frame, the slippage rate of the embedded AMM is markedly reduced, and the cost of price manipulation is exponentially elevated. Artificially manipulating prices over multiple blocks creates an opportunity for other traders to exploit the price-inflation tactic, which ultimately undermines the manipulative effort. This innovative solution offers an elegant means of executing large orders even in relatively illiquid markets. It is particularly well-suited for slow automated processes, such as governance-controlled treasury operations, that can effectively implement a dollar-cost averaging strategy over extended periods.

    Project Detailsโ€‹

    This proposal does not aim to build an alternative DEX. Instead, TWAMM will be a feature on top of the Statemine/t DEX, whose logic was renamed to pallet-asset-conversion (Substrate PR #12984) as a result of discussions on the Polkadot forum. While pallet-asset-conversion will remain independent of our TWAMM pallets, TWAMM expects an embedded AMM interface via the pallet's Config trait, which will be based on pallet-asset-conversion, making it easy for any chain implementing pallet-asset-conversion to add TWAMM to their runtime with minimal overhead.

    To handle the accounting, distribution and claiming of sale proceeds, pallet-twamm will use a Rewards trait implemented by pallet-rewards. The latter trait and pallet is not part of the application we have already developed that under GNU General Public License v3.0.

    Please note the following draft spec is subject to change during the implementation.

    Rewards (for claiming proceeds)โ€‹

    This interface is based on paper "Scalable Reward Distribution on Ethereum Blockchain" paper which presents a pull based reward distribution in O(1) per staking group, e.g. staked asset. In the context of TWAMM, stakes correspond to the sale rates and rewards to the sale proceeds. The paper assumes static stakes but the idea can be extended for dynamic ones.

    In order to keep the efficient constant proceeds accounting, we envision to map each trading pair (asset_in, asset_out) to its unique group such that the overall complexity for accounting rewards is linearly dependent on the sum of sold and bought assets, e.g. O(#assets_in + assets_out) which is much lower than O(#orders). Within each of these groups, the accounting is still in O(1) and thus independent of the number of stakers.

    Ecosystem Fitโ€‹

    Where and how does your project fit into the ecosystem?โ€‹

    We believe that a comprehensive response to this question can be found in our aforementioned sections on the Problem Statement and Solution. In essence, our solution presents a seamless opt-in extension to the pallet-asset-conversion, which can be implemented across various Substrate chains, including the relaychain, to facilitate the operation of a simplified Uniswap V2 decentralized exchange. The proposed TWAMM extension effectively addresses challenges associated with executing large orders, even within relatively illiquid markets. It particularly suits gradual automated procedures, such as treasury operations under governance control, allowing for the efficient implementation of a dollar-cost averaging strategy over extended timeframes.

    The target audience can be categorized into two distinct groups. Firstly, it caters to Parachain developers seeking to seamlessly integrate the extension on top of pallet-asset-conversion. Secondly, it also appeals to Governance participants of any chain that implements TWAMM.

    What need(s) does your project meet?โ€‹

    By optimizing the process of diversifying the native treasury in the context of a Multi Asset one, TWAMM empowers parachains to establish a DOT reserve. This reserve can be utilized for various purposes, such as acquiring a parachain lease, covering XCM fees, or enhancing availability cores during periods of high demand (once supported). Furthermore, it facilitates the disbursement of treasury grants, bounties, or even salaries in currencies with lower volatility, such as stablecoins.

    The presence of these features serves as the driving force behind the ongoing endeavor to develop a Multi Asset Treasury. In fact, the significance of this effort was underscored by a dedicated offsite meeting held in March 2023, which involved notable participants such as Gav, Parity developers, and @wischli. During the discussions, a key insight emerged - the inclusion of TWAMM within Multi Asset Treasuries would be a highly advantageous enhancement. This addition would streamline the execution of sizable orders while ensuring a robust level of security, effectively mitigating the risks associated with front-running vulnerabilities.

    Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem? If so, how is your project different?โ€‹

    The primary contributor to HydraDX, the Galactic Council, is currently developing a tailored version of TWAMM called DCA (dollar-cost averaging) within their Omnipool protocol. However, their solution is closely intertwined with Omnipool and is only compatible with it.

    Furthermore, their existing approach involves the execution of trades at regular intervals using the on_initialize hook. However, this method faces limitations when it comes to accommodating a significant volume of orders efficiently. In contrast, the TWAMM concept is founded on the principle that long-term orders do not need to be executed periodically. This is because such orders can be calculated effortlessly based on the most recent execution and are ensured to be executed before the regular orders of the embedded AMM. By adopting this approach, the need for frequent periodic executions is eliminated, allowing for streamlined and optimized processing of orders.

    Consequently, integrating their solution into Substrate parachains would involve substantial complexities and overhead. One of our USPs is the seamless and plug-and-play integration we offer for any Substrate chain that implements the straightforward BasicAmm interface. This integration can be achieved by utilizing pallet-asset-conversion or any other customized AMM.

    Additionally, Joe Petrowski, the leader of the System Parachain team, envisions our TWAMM solution being incorporated into the Asset Hub, thereby extending the functionalities of both relay chain treasuries. Otherwise, it is highly probable that pallet-asset-conversion alone would be utilized, even for slow swaps involving substantial volumes, as a means to diversify the Multi-Asset Treasury of the Relaychain, which is currently under development. Considering that significant swaps involving non-System Parachains by the Polkadot Treasury are unlikely to occur in the foreseeable future (prior to the launch of SPREE), we strongly believe that implementing a comprehensive TWAMM solution within the Asset Hub would be a substantial improvement for the ecosystem. Parties with a keen interest in a more efficient implementation may choose to execute transactions through alternative parachains, as discussed in the various DEX deliberations. If we dare to dream, we envision our proposed pallets being integrated into the frame in the future.

    Team's experienceโ€‹

    This grant is proposed by k/factory, a core development contributing to the Centrifuge project. A team made of experienced Substrate builders and a well established project in the Polkadot/Kusama ecosystem.

    We have already received and successfully delivered multiple grants:

    1. We developed a Go-based RPC library for interacting with Substrate nodes (GSRPC) as a Web3 Foundation grant in Q3 2019 and maintenance coverage as one of the first Polkadot treasury proposals in Q3 2020.
    2. We also built an early bridge together with ChainSafe in Q1 2019 and Q1 2020 which was funded by a Web3 Foundation grant.
    3. Last but not least, FUDGE received a Polkadot treasury grant In Q4 2022. This tool provides a simple and generic way to interact with and manipulate the database of a Substrate-based blockchain.

    Moreover, the k/f team has contributed to the Substrate and other related repositories in numerous pull requests, new issues and discussions. We have deep knowledge in distributed/decentralized applications, libp2p, Golang, Solidity and Ethereum overall, zkSNARKs, and tokenization of assets with NFTs and has been developing with Substrate since Summer 2019.

    Development Status ๐Ÿ“–โ€‹

    Our recent collaboration on the development of a Multi Asset Treasury (e.g. Substrate #13602, Substrate #13608) has highlighted the necessity of having a non-attackable long-term tokenswap mechanism like TWAMM (e.g. see the draft for Multi Asset Treasury). Within this context, we have engaged in discussions with the System Parachain team, particularly Joe, who has expressed support for the inclusion of our proposed TWAMM extension onto the Asset Hub. Specifically, the extension would be built upon the existing pallet-asset-conversion implementation. These conversations have provided positive reinforcement for our vision and reinforced the potential value that our solution can bring to the Asset Hub.

    We would like to bring to your attention that we recently presented a similar, albeit more extensive and expansive, proposal to the Polkadot Treasury, which unfortunately did not succeed (Motion #408). However, we firmly believe that the broader ecosystem would greatly benefit from the availability of a simple, plug-and-play TWAMM extension integrated with the pallet-asset-conversion. This would offer an alternative to exclusively routing such trades to specialized chains like HydraDX. Interested parties seeking a more efficient implementation may choose to execute transactions through HydraDX, as extensively discussed in various DEX deliberations. Additionally, Joe Petrowski's endorsement has reaffirmed our belief in this perspective, prompting us to refine our approach. Consequently, we have focused on reducing the overall scope and placing emphasis on developing the minimum required functionality. This approach aims to create a valuable addition to the Asset Hub, as well as an extension for other parachains that adopt the pallet-asset-conversion framework or have their own version of a simple constant product formula DEX.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Backgroundโ€‹

    As a versatile blockchain framework, Substrate has a variety of modules (a.k.a. pallets) for developers to reuse. From resource management such as accounts and assets to utilities such as random number generators and schedulers, these existing pallets could meet the need of most developers' application scenarios. However, there is still room for improvement.

    Recently we have a requirement to implement a data storage service on Substrate, and after checking through all existing pallets, we did not find one that meets our need. So we would like to develop a custom pallet to fulfill this purpose.

    We are not talking about something very niche here. On the contrary, it is a common scenario that an application would continuously consume and generate various data, whether it is system, user, or just temporary levels, during operations. Many dApps have a large number of scenarios that require off-chain data storage services, such as NFTs. The quality of the storage service chosen will directly affect the performance and reliability of the entire application.

    So we hope to offer Substrate/Polkadot community with pallets (and toolchains) dedicated for storage services that are compatible with current Substrate APIs. So developers only need to add tiny amount of code change to leverage CESS stable and secure data storage. We believe this will further enhance the development experiences when adopting Substrate and enrich the Polkadot ecosystem.

    Current Solutionโ€‹

    There is only one pallet related to data storage in the existing Substrate FRAME, aka, Transaction Storage Pallet. It supports running an IPFS node side-by-side with Substrate and allowing data to be retrieved by IPFS after putting it in Substrate storage. However, its application scope is greatly limited due to its inherent characteristics and several defects in the following aspects.

    1. Data need to be uploaded to the blockchain network. Although this data is not actually stored on the chain, they still incur additional gas costs and congestion, which is not suitable for large file storage.

    2. All validator nodes need to establish IPFS service for themselves, which subject to many restrictions.

    3. The development is difficult since the Substrate-based code needs to be greatly modified.

    4. This only supports file upload on the Substrate side. Viewers need to retrieve it via IPFS clients.

    Project Detailsโ€‹

    We design and implement a data storage service based on Substrate. On one hand, there is no need for a validator node to start additional service, and no major modifications to substrate-based code as well. Therefore, developers can easily integrate our storage service, whether it is a newly-built chain or an existing chain. On the other hand, by customizing the storage REST component, users could upload and download data conveniently without installing additional client programs.

    High level designโ€‹

    Our proposal architecture is shown in the figure below, which consists of the Data Store Pallet and custom-built Storage Sidecar (inspired by Substrate API Sidecar).

    Figure 1: Proposal architecture

    Figure 1: Proposal architecture

    • Data Store Pallet: Realize the recording and management of stored data. This pallet implements functions related to meta-data, e.g. root data management, data owner management, and data classification regarding the stored data.

    • Custom-built Storage Sidecar: Provide RESTful service to interact with Data Store Pallet. The difference from Substrate API Sidecar is that, in addition to the basic functions of interacting with the substrate-based chain, Storage Sidecar encapsulates storage-related API, including data storage and data retrieval. The data transmitted by users will eventually be stored in CESS Storage System through this interface.

    Typical exampleโ€‹

    Data storage and retrieval are the two core features for a data storage service. They are illustrated in details below.

    Figure 2: Typical example process

    Figure 2: Typical example process

    • Data Storage
    1. A user calls the data storage API of the Custom-built Storage Sidecar to upload the data file;
    2. Forward the data to CESS by calling the encapsulated CESS API;
    3. Once it is confirmed that the data has been written, Custom-built Storage Sidecar will call Extrinsic to record the relevant information of the data file on-chain;
    4. CESS Storage System maintains the integrity and privacy of data throughout its life cycle.
    • Data Retrieval
    1. A user calls the storage API of the Custom-built Storage Sidecar to retrieve the target data;
    2. Custom-built Storage Sidecar to query on-chain data routing information;
    3. Call the CESS data retrieval API with the routing info;
    4. Retrieve and return the target data from CESS Storage System;
    5. Return the target data to Custom-built Storage Sidecar;
    6. Custom-built Storage Sidecar updates on-chain information, if necessary;
    7. Return the target data to the user.

    Development Roadmap ๐Ÿ”ฉโ€‹

    This section should break the development roadmap down into milestones and deliverables. To assist you in defining it, we have created a document with examples for some grant categories here. Since these will be part of the agreement, it helps to describe the functionality we should expect in as much detail as possible, plus how we can verify and test that functionality. Whenever milestones are delivered, we refer to this document to ensure that everything has been delivered as expected.

    Below we provide an example roadmap. In the descriptions, it should be clear how your project is related to Substrate, Kusama or Polkadot. We recommend that teams structure their roadmap as 1 milestone โ‰ˆ 1 month.

    For each milestone,

    • make sure to include a specification of your software. Treat it as a contract; the level of detail must be enough to later verify that the software meets the specification.
    • include the amount of funding requested per milestone.
    • include documentation (tutorials, API specifications, architecture diagrams, whatever is appropriate) in each milestone. This ensures that the code can be widely used by the community.
    • provide a test suite, comprising unit and integration tests, along with a guide on how to set up and run them.
    • commit to providing Dockerfiles for the delivery of your project.
    • indicate milestone duration as well as number of full-time employees working on each milestone.
    • Deliverables 0a-0d are mandatory for all milestones, and deliverable 0e at least for the last one. If you do not intend to deliver one of these, please state a reason in its specification (e.g. Milestone X is research oriented and as such there is no code to test).

    โšก If any of your deliverables is based on somebody else's work, make sure you work and publish under the terms of the license of the respective project and that you highlight this fact in your milestone documentation and in the source code if applicable! Teams that submit others' work without attributing it will be immediately terminated.

    Overviewโ€‹

    AIKON is dedicated to driving mass-adoption of blockchain. We would like to bring our flagship ORE ID service to Polkadot, Kusama and to a variety of parachains. However, in order to build our API service on Polkadot & Kusama, we need an open source library called ChainJS. ChainJS is an abstraction layer that allows web applications to interact directly with Polkadot using javascript. This standard provides a handful of easy methods for common interactions on-chain, like creating wallets, transferring tokens and signing transactions.

    Once we have this ChainJS plugin, we can work with companies to launch tokens or applications on Polkadot with ORE ID. For example, with Republicโ€™s Note token, they use ORE ID to create multi-sig wallets for their investors and the investors use their ORE ID login to sign transactions, but ChainJS actually forms the transactions and sends them to the blockchain.

    Our goal is to establish ChainJS as the de facto standard for javascript developers that want to build on Polkadot & Kusama.

    • Open Source standard for Javascript
    • Easy to use abstraction layer for web developers - unlike Polkadot.js, ChainJS simplifies the interface layer making it easier for new developers
    • Makes it easy for developers to build on Polkadot, Kusama and on parachains, that can roll out their own fork of the ChainJS library
    • Allows AIKON to deploy ORE ID for companies on Polkadot & Kusama

    Once we have ChainJS, ORE ID provides four major benefits to businesses:

    • Consumer friendly user experience - including social and email login
    • API for mass migration of large existing databases of users
    • Fiat invoicing for Polkadot & Kusama transactions

    Ecosystem Fitโ€‹

    Although there are javascript tools for Polkadot like https://polkadot.js.org/docs/, this is the first effort to create a ChianJS plugin for Polkadot. The ChainJS standard is particularly suited for helping applications form Ethereum migrate to Polkadot, and we also hope it provides a template for parachains to do the same. ChainJS is also critical for the ORE ID product to support Polkadot, allowing us to help drive business adoption of Polkadot and parachains.

    Chainviz alpha version currently utilizes SubVT backend services and Polkadot JS API as follows.

    • SubVT active validator list service
      • List of all active validators
      • For each validator, a summary including:
        • Identity
        • Validator preferences
        • Self stake
        • Nomination count and total amount,
        • 1KV data if exists
        • and more
    • SubVT network status service
      • Era index
      • Era reward points
      • Total, minimum, maximum and average stake amounts
    • Polkadot JS API

        • Utilized to mark finalized blocks
      • Best block header subscription
        • Utilized to display the block production animation
        • Identify uncle blocks and visualize them

    Current Chainviz alpha version system architecture can be illustrated as follows.


    Figure 1 Chainviz alpha system architecture

    Proposed Upgradeโ€‹

    Proposed upgrade to the first major version requires the following additional data:

    • Block content
      • Extrinsic list
      • Event list
    • Parachains
    • XCM messages

    Proposed system architecture for the upgrade can be illustrated as follows.


    Figure 2 Chainviz v1 proposed system architecture

    Upgraded system utilizes:

    • Polkadot JS API to access block content and parachains, and subscriptions for new and finalized block headers
    • SubVT Polkadot and Kusama Active Validator List Services for the list and summary data for active validators
    • SubVT Polkadot and Kusama Network Status Services for live network data
    • Polkaholic XCM API for the live display of XCM messages and their summaries

    UI/UX Upgradesโ€‹

    We're going to implement a number of UI/UX upgrades, as follows:

    • Improvement of the overall aesthetics and visual coherence of the application
    • A better depiction of the block production process that is easier to comprehend for a wider range of users from the technically informed to the newly-introduced
    • Display of block contents (i.e. hash, number, author, extrinsics and events) on click
    • Responsive design for a range of screen sizes
    • A better utilization of the 3D space to allow for parachain visualization and preparation for future upgrades
    • Display of parachains, their assigned validators and the cross-chain messaging process

    UI/UX upgrade implementation consists of 3 core components:

    • Visual guidelines
    • Application UI/UX upgrades
    • WebGL graphics development and motion design upgrades

    Development of the visual guidelines aims to bring visual coherency to Chainviz. From a functional perspective, this component serves as a core visual guide and foundation for all future UI/UX components and 3D graphics development.

    UI/UX upgrades aim to elevate the project from a draft look to an efficient, performant, user-appealing, scalable web application. Visually, it will be based on the current project aesthetics while ensuring its responsiveness and accessibility. Through this work, we aim to increase usability and ensure application scalability in terms of functionality growth.

    Third component of the visual upgrades, the development of the upgraded WebGL graphics and motion, faces a set of challenges that we aim to solve, including effective visualization of the block production and cross-chain messaging process. When we use the term effective visualization, we primarily mean one that:

    • Can show the depicted processes in a simple yet systematic manner
    • Can be engaging and valuable for users with different levels of expertise

    Ecosystem Fitโ€‹

    There is currently no direct match in the Dotsama ecosystem of the features offered by Chainviz. Chainviz Alpha got shared on Twitter by Gavin Wood upon initial release, and received a lot of praise from various Dotsama ecosystem members.

    There are currently two other projects that visualize certain aspects of the Dotsama blockspace:

    1. Kusamaverse by Odyssey, which is closer to a metaverse space for Kusama, focuses more on the interaction of the actors in the ecosystem.
    2. XCM Dashboard by the Subscan team, which is a fairly static visualization of the active cross-chain messaging channels between parachains.

    Chainviz is unique in that it focuses on a very clear real-time visualization of the internals of the Dotsama machine. As we're going to explain in the Future Plans section, it also has the potential to have educational, entertainment and functional value through future development.

    Team's experienceโ€‹

    We have applied and deliverd all milestones of the SkyeKiwi Protocol and built the SkyeKiwi Network based on SkyeKiwi Protocol as a privacy layer for Web3 featuring interoprabl, multi-shard, multi-vm private smart contract execution as a part of the Substrate Builder Program. We have a track record of engineering complicated system with high quality. The Choko Wallet is a critical component for the adoption of the SkyeKiwi Network (and the SkyeKiwi Protocol), from the encryption/decryption functionalities of the network. More discussed in future plan section.

    Team Code Reposโ€‹

    Development Status ๐Ÿ“–โ€‹

    The project is mostly front-end work, except for the mechism for cross-browser tab communication from the Dapp and wallet. Therefore, so far, we have only created a simple sandbox to demostrate the viability of such communication here.

    Moreover, the Near Wallet (an Apache2.0 or MIT licensed open source software) seem to be a good base of development for Choko Wallet. We will fork the repo and do a complete overhaul to better fit the needs of the Polkadot ecosystem.

    Update on August 2 on Near Wallet: after a month long dig into the Near Wallet codebase, we recognize the following issues that prevent us to build upon the Near Wallet but instead, start a new codebase of the Web App from scratch:

    1. Chaotic state management: the Near Wallet has very tangled state management for requests and responese. As it will be more efficient to build the underlying redux dataflow from scratch.
    2. Different account system and different cryptographics: the NEAR blockchain uses Ed25519 for pretty much everything, while on Substrate, Sr25519 is used in default but there can be all kinds of cryptographic used in the Polkadot ecosystem. (i.e. Moonbeam). Moreover, NEAR is based on a human-readable fake AccountId that links to several cryptographic "keys" for accounts. These are factors that contribute to point 1 of why the Near wallet codebase has such a complicated Redux dataflow.
    3. Loose Encoding on URL: as we stated above on "Requst Handling", we will build a byte percise(and efficient) version of the encoding to be sent between Dapp and Wallet as Substrate extrinsics can be very long on cross-chain communicattions.
    4. Decentralziation: lots of functionalities of Near wallet relies on a closed-source centralied helper service. We don't want that.
    5. Extensibility: the network RPC is hardcoded into NEAR. Choko Wallets need to support a wide range of networks, while we will allow networks to customize their own request handling mechnisim, while have a set of functionalities by default. Such design will require weeks to peel off wallet logics away from the near codebase.
    6. Security: the near wallet does not require a user input password to safeguard the seed phrase. This can be considered "kind of" secure because of the AccountId system of Near(i.e. Keys are ephermeral, while a human readable AccountId like "alex.near" is presistent). However, this is not applicable to the Polkadot ecosystem. To change so, we would also have to completely peel away the private key management logic from the near codebase.
    7. Frontend Framework: we decided to go with Next+Tailwind+Redux+TypeScript combo with good lint/test/build pipeline for better maintainablity. And avoid the messy codebase as the Near Wallet.

    Are there any other projects similar to yours? If so, how is your project different?

    The most similar to what we are building at Citadel is Lunie. However, some features and platforms' details are different - it provides DOT holders with an opportunity to choose what's best for them.

    To begin with, as multi-asset platforms, Citadel and Lunie support different networks. Thus, depending on the user's portfolio,one of the platforms will be more preferable, than the other. For example, if a user holds DOT and XTZ, Citadel will become a good all-in-one solution; in the same manner, if a user possesses DOT and AKT, it may be easier for him to use Lunie. In addition, Citadel supports Bitcoin, Ethereum, and Tether for the comfort of our users.

    Furthermore, we integrated the fiat gateway and instant cryptocurrency exchange so that users can effortlessly buy tokens right in the app. Also, Citadel users have access to their transaction history details and a full analytical dashboard that allows them to track all the assets across multiple networks with a proper reward calculation. Lunie and Citadel have absolutely different interfaces, so users are free to choose the most suitable solution based on their specific needs. Below, you can find a quick comparison table.

Our team consists of specialists that are apt to cover all the tech needs โ€“ from DevOps and node administration to backend & frontend handling. What's more, with the significant business, and finance knowledge of Alex Falko, vast project & product experience of Anton Pavlutsky, and the all-encompassing hard skills of Gregory Shabalov, the Citadel team is competent in supporting sustainable growth and development.

    As for the team's interesting cases, we shall begin with our co-founders' experience. Feel free to check out interviews with Anton and with Gregory, where they cover all of their relevant career experience. Furthermore, our dev team did hard yet interesting work with standardizing the tech stuff for all integrated networks: they coped to parse Tezos, ICON, IOST, Ethereum, Cosmos and bring them to the unified database storage standard so that the analytics can be provided in the quickest and the most convenient way.

    Our Lead Backend Developer, Pavel, was apt to unload transactions in the shortest possible time by restructuring the parsing and data saving process using the streaming method. He also found a way to optimize the logic of wallet generation for different networks in order to reduce the number of libraries used and get a much faster website experience for users. Now Pavel is working on an extremely interesting instance associated with decoding the encoded Ontology byte data into a readable form.

    Overviewโ€‹

    Introductionโ€‹

    Clover is a Substrate-based Polkadot parachain which is committed to providing easy-to-use blockchain infrastructure by creating a one-stop comprehensive infrastructure that ultimately reduces the threshold and cost for the DeFi community.

    Clover provides a perfect gateway to DeFi for everyone including those who are completely new to DeFi. We bridge the gap between the crowd and the DeFi world via a user-friendly front end portal with an easy-to-navigate multi-chain wallet, block explorer/DeFi application market for regular users and a user-friendly built-in protocol library that allows developers to easily deploy their own applications. Without the need of managing multiple assets in different accounts, Clover enables users to keep track of whatโ€™s happening real-time in one place.

    Integrationโ€‹

    We decided to develop on Polkadot mainly because of its enhanced scalability and low-in-cost among other smart contract platforms in the space. As a sharded multichain network, Polkadot allows the processing of many transactions on different chains in parallel that most legacy networks do not. While providing scaling solutions through parachains, Polkadot development is steadily advanced, has gathered a large number of developers from the community, and numerous projects are emerging endlessly in the ecosystem. On the other hand, Polkadotโ€™s Substrate technology provides a relatively easy-to-use and highly customizable framework that allows us to build our platform to communicate with other ledgers, which in a sense will likely attract more users to onboard in the future.

    Clover will compete to join as parachain for Polkadot and is committed to becoming a digital finance portal and DeFi service provider on Polkadot. Focusing on both to-C and to-B users, Clover will provide a series of DeFi related products and services to meet the diverse needs of different users. At the same time, developing and providing a modular DeFi protocol, which greatly reduces the technology development threshold for upper-layer applications. Clover will put together a large user base and different projects into a one-stop open and integrated financial service platform on Polkadot, using Substrate framework, to communicate with other existing parachains such as Bitcoin and Ethereum parachains. Namely, Clover will be another parachain on Polkadot. Once the parachain gets the slot to join the Polkadot relay chain, they can communicate with each other through Cross-chain Message Passing (XCMP) protocol. That means Clover can build its DeFi with the other parachain assets, like the DeFi protocols on Ethereum.

    Team Interestโ€‹

    We are a team of like-minded people who have a dream of building a groundbreaking technology towards censorship resistance on utilizing newest additions to DLT technologies. Apart from incentivizing our core team with a structured/periodic compensation plan throughout the next 5 years with cliffs imposed in between, we give ourselves a high degree of autonomy and lots of space for creativity overall.

    An overview of the technology stackโ€‹

    The bottom layer of Clover OS is built on blockchain. Application states are built on the Polkadot network, and the storage is built on IPFS. Leveraging on Polkadotโ€™s parachain technology, Cloverโ€™s core advantage lies in its control panel. It can easily dock various user actions provided by its backend that has been integrated by a variety of tools including Wallet, Block Explorer, Polkadot-JS, and more. As a result, users can be connected, transact on various chains and integrate their corresponding functions with the support of Clover. Clover will collect incoming data and clean them, with our proprietary database and inhouse algorithm, data will undergo different sets of validation and analysis before they get applied and translated into visualizable data. Building on Substrate, Cloverโ€™s application terminal is determined to become the entrance to the global digital finance world with state-of-art simplicities. With accessible tools, better support, and lower cost, we are likely to see more applications to be developed on Polkadot in the future. Clover will foster a diversified and scalable DeFi environment that allows for more possibilities.

    Ecosystem Fitโ€‹

    As a decentralized financial service provider on Polkadot, Clover provides modular DeFi protocols and application tools, which greatly reduces the repeated efforts needed in the protocol development. Modular DeFi protocols include Staking Liquidity Protocol, Decentralized Trading Protocol, Decentralized Lending Protocol, Token Dividend Protocol, Governance Protocol, and Synthetic Asset Protocols. Clover allows its upper-layer application projects to focus on improving user experiences and accelerate innovations of diversified financial applications through its composability. Clover can potentially convert a large number of DeFi users into users of its upper-layer applications. This way, upper-layer applications will be able to bootstrap its community and inject more market values.

    Clover will also establish a developer-centric community. In addition to giving rewards to those who provide constructive contributions, Clover will encourage its third party developers to continuously build innovative dApps on top of Clover. Each project built on Clover by the third party developers will require a solid financial foundation, and generally donations from the community are insufficient to cover development expenses which results in stagnated growth. Therefore a sound funding mechanism has been established, The Developer Incentive Program, where all the projects building on Clover can benefit from a share of transaction fees. The Developer Incentive Program (DIP) is a Clover-native consensus feature that aims to direct a percentage of transaction fees to registered smart contracts to incentivize in Clover third party contract developers and commons, mainly to boost external dApp development which ultimately enlarges the Clover DeFi ecosystem overall. The program is consistent with Cloverโ€™s properties of being a decentralized operating system which does not touch the inflation schedule or alter the scarcity of CLV, but effectively increases the security of smart contracts against bugs and software vulnerabilities by enabling external development to be properly funded. Overall the benefits of the plan create the potential for a very exciting future in which Clover can grow and compete, and can reach its goal of becoming the best possible DeFi platform for all. Therefore Clover, whose key role is to be the service provider of which will allow a variety of applications to be built on top, aims to become a one-stop financial services platform that highly incentives users, developers, and upper-layer applications to innovate.

    With the rapid development of DeFi, the demand for insurance protocols is also increasing and has become an important part of the DeFi protocols. At the current stage of DeFi development, it is not yet possible to directly trade assets such as stocks, precious metals, and commodities. However, the synthetic asset protocol will allow simulations of assets price and facilitate transactions on the blockchain. In addition, the developer community we established will also become a source of innovative DeFi protocols. Clover allows modularization of the different protocols, thereby providing a resourceful module library for upper-layer applications, which will ultimately enable the creation of more diversified financial applications. With the help of Bithumb Global bootstrapping the liquidity of Clover by co-sharing its marketing and community resources, we will be advising Clover on the go-to-market strategies and PR placements as well as launching campaigns, educating Bithumb users, and distributing to our network.

    We will start to build the developer community when TestNet is ready and SDKs are available in Q1 and Q2 2021. Detailed documentations will be provided and more contents about developing applications on Clover will be released by then. We will work with some existing developer community to hold events, as well as holding/supporting hackathons to acquire more developers once developer kits are ready in Q2/Q3 2021. Bug bounty programs will be held when Mainnet is launched. For the user community, we plan to work with some industry media to release publications. Clover maintains its social media including Twitter, Youtube, Medium, and more to provide self-generated content, and covert followers and users to our Telegram, Discord, and Kakao groups. Marketing campaigns will be held to keep user activeness while Clover will focus on incentivizing users to participate in liquidity mining and governance activities. Key metrics of campaigns include the number of new user growth, the number of token holders, the number of members in the developer and the overall community, social media followers, total value locked (on liquidity mining applications), and number of votes.

    Development Status ๐Ÿ“–โ€‹

    The project consists of a research part (conceptual framework) and a development part (open source data collection tool). The first phase of the research part has been completed.

    Conceptual Frameworkโ€‹

    We began to work on the community health check in Spring 2022. We have assembled a team including two PhDs in network science and an organisation designer with significant DAO and community building experience to bridge both theory and practice. Weโ€™ve reviewed over 50 papers on community, social network analysis, resilience, trust, engagement, and more. We synthesized the findings to define key indicators with high validity and predictive capacity for community health, while also taking a holistic perspective that accounts for memberโ€™s wellbeing.

    We have published our conceptual framework. This framework describes the different nested systems within a community and details a number of metrics (vital signs). It incldues insights from one of our team members on network resilience network biomimicky.

    Data collectionโ€‹

    For the data collection tool, weโ€™re going beyond traditional surveys by combining interaction data with short, targeted pulse surveys. Interaction data provides us with objective data about what is happening inside the community (social network data). While pulse survey data offers insights into members' beliefs and emotional attachment to the community (pulse surveys).

    The data is anonymised and collected in a central repository for this first phase (weโ€™re exploring decentralised hosting) and managed by a team having received ethics training and at risk of losing their credentials should it be misused.

    Currently, the data pipeline for Discord is ready and functional. We have used Discord's API to fetch the data. In February we did a soft launch of our dashboard which only visualises Discord activity. The charts for displaying our custom-build engaged and disengaged members categories are being implemented in March 2023.

    At the end of 2022, we have begun conceptual work on how to analyze Twitter and on-chain data. Efforts have remained conceptual as we were focusing on our first data pipeline (Discord).

    We have started to build the designs for the pulse survey functinality and will begin user-testing the prototype end of March 2023.

    Analyzing conversations in private channels (e.g., Discord) is within a grey zone of private and public conversations and a sensitive issue. Servers and channels that are not gated in anyway (token or role) are akin to public conversations as there are no barriers for people to enter and join the conversations. On the other hand, once users need to fulfil certain criterias or pay in order to access a server/channel, the conversation could be perceived as private. This distinction has ethical and legal consequences.

    For this reason, we have worked with a legal counsel via LexDAO. As part of this, two lawyers have reviewed the process from fetching data and presenting results to ensure we are within GDPR laws. On Wednesday 22nd February we had a GDPR session for our team and implemented the lawyers' recommendations.

    Once our process from data fetching to analysis will be fully automated, we will

    Implementationโ€‹

    To date, we have delivered six community health reports (Aragon, MetaGame, Verida, Canabis Genom DAO, LexClinic, Aave), built a prototype of our dashboard and conducted 12 user interviews.

    After our first report, we have adopted a step-wise approach to integrating the network metrics, focusing on providing a clear, concise, jargon-free explanation. In addition, we have included a simulation section in our health reports to showcase what the health metric could be if the interaction pattern changes or if there is a large change in the community size.

    While the development of the full dashboard is ongoing, we continue to deliver low fidelity dashboards to interested communities. This lets us interact closely with users, helping us learn more about their problems and shape onboarding material for users. Interested communities get direct access to our team of data scientist who happily investigate follow-up questions.

    Early development of this project has been funded by Aragon, Polygon DAO, Aave, MetaCartel and Near.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    We are following a grant-matching processes to spread the risk among different communities.

    Milestone 1 - Defining metricsโ€‹

    Research social network metrics that are viable to measure the health of a community on Twitter, and how they integrate with our existing community health framework. This will build on our existing framework, extending it to metrics that have been tested and used in Twitter communities. For example, we will look into approaches to build the network, virality and clustering/fragmentation of very large online communities.

    Note: We have done an evaluation to decide wheter Reddit or Twitter would be a better option. In the discussion we had with other communities, we were more often asked about an integration with Twitter than with Reddit. Hence, from a scaling perspective, we decided that focusing first on Twitter makes more sense with us.

    That being said, we realize that Twitter is undergoing a lot of changes, and we might have to do a last minute pivot to another platform. We are building our analytical scripts in such a way that they can easily be used for other platforms. Therefore, the only thing that has to be changed in the milestones is the name of the platform.

    Milestone 1 will be focused on research. Hence, we're not going to deliver the following usually mandatory deliverables:

    NumberDeliverableSpecification
    0a.LicenseThe results will be published open-access using an Apache 2.0, GPLv3, or MIT license. We will decide later which one is most suitable for the written document.
    0e.ArticleWe will publish an article (technical document) describing the metrics, the insights (so-what), and limitations. This article will also explain how the Twitter community is build (e.g., who are nodes, when there is an edge between two people, who is excluded/included and why). We will build a directed network, where nodes are always Twitter users. From a network assembly perspective, we will not differentiate between accounts representing people and those representing communities or organizations. The edges between an user profiles are either a reply, quote, mention, retweets, or likes. Thus, a tie from user A to user B exists if (1) user A replies to user B, user A quotes user B, user A mentions user B, user A retweets user B, or user A likes user B's tweet. At this moment, we will created weighted edges, not making a conceptual difference between the interaction type (reply, quote, mention, retweets and likes).The article will not be behind a paywall. The article will be written for an audience comfortable with data analysis.

    Milestone 2 โ€” Twitter community health dashboardโ€‹

    This milestone implements the work from the previous milestone by building the dashboard. It will be build using the Twitter API v2. This comes with the following rate limits:

    Given the rate limit, we will see how users will be able to combine different accounts (e.g., parachains, dApp developers and other teams that build on Substrate) to create a holistic picture of their community.

    0d.DockerWe will deliver a docker file to tests the functionality.
    0e.ArticleIn addition to the dashboard, we write a handout. This is a walkthrough of the dashboard, explaining each metric, if the score is good or bad, and a list of recommendations.
    1.Twitter data pipelineWe will create a data pipeline fetching data from Twitter using their API. The user will enter one or a few twitter handles. The data pipeline is build using Python. We have already a data flow for Discord visible in the following repos: Discord bot, interactions with db, and interactions between front-end and db.
    2.Twitter dashboardWe will extend our dashboard to include a page with Twitter community health data. The dashboard is build using Typescript. Our current dashbaord, build on Discord data, is available in this github. We will add the Twitter metrics to this dashboard.
    3.Workshop/callWe will hold a workshop/ call to answer any questions about the dashboard and handout.

    Future Plans:โ€‹

    We have three workstreams for our future: New metrics, new integrations, new analytical methods.

    New Metrics and Integrationsโ€‹

    New metrics and new integrations will provide incremental improvements of the dashboard and will largely be driven by scientiic research for new metrics and user research for new integrations.

    New analytical methodsโ€‹

    We are currently developing a pulse survey functionality to measure members perception of the commnunity. This provides a subjective insight on community health currently missing in the data. We are looking at text analysis and GPT3 to help community members and moderators gain an overview of important discussions and information.

    Cross-chain Wallet - XCW

    • Team Name: Blockcoders
    • Payment Address: Ethereum (USDT/USDC/DAI) 0x1Ff29471bf02399A5B6Bd096A13d43982dFac357
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    Blockcoders is proud to propose the development of a revolutionary cross-chain wallet, capable of importing and creating both EVM and WASM accounts. This wallet will make it easy for users to manage and transfer tokens between the two chains. Built with the user experience in mind, the wallet will feature the same sleek and intuitive design as Astar UI. The term cross-chain in this case refers to the ability to transfer tokens between parachains for both EVM and WASM. We plan to give constant support to this wallet and open Telegram and Discord channels to have a better feedback from the users, solve issues and add new functionalities.

    Goalsโ€‹

    • Develop a user-friendly wallet that simplifies the management of EVM and WASM accounts in one place.
    • Enable seamless and secure asset transfer between users accounts on different chains.
    • Provide a safe and intuitive platform for users to sign messages and interact with dApps.
    • Enhance transparency and accountability by displaying transaction details and links to scanner/explorer pages.
    • Maintain the wallet's decentralization and open-source nature, ensuring its trustworthiness and security.
    • Aim to cover more than 90% of the wallet's main functionalities to provide a comprehensive user experience.

    Securityโ€‹

    The wallet will implement the Keyring concept, which is the core of the secret storing and account management system in MetaMask. This approach ensures that private keys are stored locally on users' devices using browser built-in storage capabilities such as IndexedDB or WebSQL, making them accessible only to the user. Additionally, we will use encryption techniques similar to MetaMask, such as PBKDF2 iteration and AES-GCM mode, to provide an extra layer of security for the private keys. This wallet will also implement the same feature that Polkadot's extension has, which allows users to see the availability of different parachains before they make a transfer. This feature will provide users with an added layer of security and peace of mind, as they can ensure that their transfer will go through smoothly.

    Specificationsโ€‹

    In a first approach, we will be using the following technologies: React, Typescript, Polkadot API and Ethers.js. The supported browsers will be: Chrome and Firefox. The default networks will be: Astar, Shiden, Shibuya (testnet), Moonbeam, Moonriver, Moonbase Alpha (testnet), Polkadot and Kusama. The default tokens will be: ASTR, SDN, SBY, GLMR, MOVR, DEV, DOT and KSM.

    Main functionalitiesโ€‹

    • Allow users to easily create and import EVM and WASM accounts.
    • Provide a clear and intuitive overview of users' balances for both EVM and WASM accounts.
    • Enable the transfer of assets between EVM accounts, WASM accounts, and between EVM and WASM accounts.
    • Allow users to sign messages and execute calls and transactions on custom smart contracts.
    • Provide links to explorer pages to enhance transparency and accountability.
    • Give users the flexibility to add custom networks and tokens to the wallet.
    • Implement the XCM format to enable cross-chain functionality, making it easy for users to transfer assets between parachains.
    • Design the wallet using React and follow the look and feel of Astar UI, with the option to open in full-screen mode.

    The cross-chain functionality will be implemented using the XCM format, enabling users to easily transfer assets between EVM and WASM parachains. The XCM implementation will be simplified to provide a seamless user experience. The user interface will be built using React, and the design will be inspired by the look and feel of Astar UI. The extension will have the option to open in full-screen mode for a more immersive experience.

    Ecosystem Fitโ€‹

    Help us locate your project in the Polkadot/Substrate/Kusama landscape and what problems it tries to solve by answering each of these questions:

    • Where and how does your project fit into the ecosystem?
      • This wallet is a perfect match for the ecosystem as it provides a solution to the problem of having to use multiple wallets to interact with different types of accounts such as EVM and WASM.
    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?
      • The target audience is anyone that interacts with the ecosystem using a wallet. From developers to final users.
    • What need(s) does your project meet?
      • It provides a solution that today it's resolved by using multiple wallets/applications.
    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?
      • There aren't any other wallets that support both EVM and WASM accounts and the ability to send assets between them.

    Project Overview ๐Ÿ“„โ€‹

    In the previous grant, we built a tool that can automate building rust game projects for Android and iOS and tested it on applications with base elements such as 2D image / 3D model rendering, music, touch events, networking (substrate communication), etc. Also, we made it engine agnostic, and the process itself of creating similar apps pretty straightforward. But there are plenty of things left to do to provide full support of features for more advanced games: like notifications, permissions, in-app purchases, better sounds and music support, Google Play/Apple ID authentication, AdMob, iOS Bitcode, Android Application Bundles, or AAB, etc. Most of these problems are not easy to solve, and many projects facing them are moving to more popular engines because you never know how much time it will take to add IAP or authentication to your project in pure rust. So our intention on this grant is to continue fixing and adding the most crucial components of games so that the whole rust community can use them in any rust project without any problems.

    Overviewโ€‹

    Crossbow - Cross-Platform Rust Toolkit for Games.

    A goal of the crossbow project is to provide a complete infrastructure for game development in rust. In addition, the project simplifies the creation and packaging of crates for Android, iOS, and other platforms. Finally, we want to make most of our tools - engine agnostic to help rust game developers integrate them into their games, engines, and crates.

    Plenty of Polkadot / Kusama / Substrate game projects want to develop their games in pure rust game engines, but as there's no well-tested and reliable software - they choose standard game engines. It's terrible for the Substrate ecosystem in several ways: 1. they could enhance the rust ecosystem; 2. generate more rust jobs that will potentially start own Polkadot projects in the future or contribute to the ecosystem itself; 3. miss an opportunity to integrate full or light Substrate node directly in-game for peer2peer synchronization and a lot of other exciting stuff.

    Of course, there are already a bunch of promising game engine projects, but they almost all don't provide at least adequate support to simple tools like mobile permissions, game SDK, auth, achievements, etc. That's why we want to create a single game toolkit for the most popular platforms.

    Team's experienceโ€‹

    The team was involved in creating an internal NFT Marketplace white-label (https://marketplace.10clouds.io). As the name suggests it's a website that allows mint and trade NFTs between users. It is strongly inspired by OpenSea and follows the same lazy minting pattern. After login with Metamask user can customize the profile, create collections, and start lazy-minting NFTs. The website contains extensive search/filters for collections and NFTs. An NFT can be created as Open for offers which means another user can offer a price for which they want to buy it and the owner can accept any of them. The other way of selling is the โ€žBuy now" option which allows you to sell NFTs for a set, fixed price. In both scenarios, the NFT is minted during the sale process and transferred to the new owner.

    The app is written in Next.js on the front-end and contains our own Smart Contracts currently deployed on Goerli testnet, and the Backend is written in Python with GraphQL. We have our own subgraph created in The Graph to aggregate the information about events emitted from our contracts (to update the UI accordingly).

    Development Status ๐Ÿ“–โ€‹

    We are currently in a very initial phase of gathering benchmarks for the approach and setting the general approach to deliver an experience that fits the target audience.

    From our initial research we came to the conclusion that the solution should follow these traits:

    Using a Jamstack approach & Webflow templateโ€‹

    We aim to provide front-end templates that can be used with one major static site generator (SSG). This follows similar approaches like Github Pages templates for projects that contain the most important information and link-stubs to make it easy for Github projects to present themselves.

    The Jamstack will allow us to leverage the vast community behind it for future involvement of customisations and ports to other SSGs as is evidenced by the activities of these communities who are eager to port interesting templates to their SSG of choice.

    In addition to this we plan to create a Webflow template variant for teams who are more comfortable with it. Optionally we can also publish the Figma design as a basis for custom layouts by the community.

    One Page approachโ€‹

    We will also suggest a One Page or Single Page approach that, while still having the option for a menu, presents all information in one page as the name suggests. This has the following advantages:

    SSG support (Jamstack only)โ€‹

    We aim to start with the support of Astro, a popular React-based choice for SSGs, with a vast community of its own. An initial survey of the Parity community should be done to see whether these assumptions match and should be revised.

    When it comes to other SSGs, the ports can either be motivated by further grants or left to the community of open source volunteers. As mentioned before, there is an intrinsic motivation of each SSGโ€™s community to port popular templates.

    Deployment choices (Jamstack only)

    The Jamstack approach allows the community to use virtually every popular way of hosting the project sites. We are assessing whether it is beneficial to include a โ€œDeploy to Netlifyโ€ button in the projects as well to lower the initial barrier. However, projects will be able to deploy their pages to (but not be limited):

    Easy to get startedโ€‹

    Weโ€™re assuming that the approach is also a familiar way for the Parity community to get started with their project pages. Itโ€™s as simple as fork, customize, deploy.

    For parts of the community who are less comfortable with the Jamstack approach we will provide a Webflow template as well.

We verify the signature by using the DLEQ proof to verify that the secret key used to seal the block was constructed by the proper slot winner.

    Encryption-to-Future-Slotsโ€‹

    Overviewโ€‹

    We propose an Encryption-to-Future (EtF) scheme on top of the modified Aura consensus proposed above. We enable two flavors of EtF, one which allows for encryption to specific slots in the future (but which relies on a single authority for decryption, who could release the key early or not at all), and another which allows for encryption to specific epochs and requires a threshold of authorities to seal blocks to enable decryption.

    The high level idea for encrypting to a specific slot is that given a duration of time, $t$, we can identify a 'slot seed', a role to which we can encrypt a message such that it will be decryptable after time $t$ passes, when the corresponding secret will be published. We accomplish this by:

    As can be seen, it will be paramount that all participants agree on the same 'time'.

    The second type of EtF that we enable uses the threshold scheme setup in the IBE Block seal section to decrypt data. We build this off of the previous result (encryption to a slot). Here, we aggregate the public keys $\hat{Q}$ derived from each authority's identity and use the same BF IBE scheme to encrypt a message for the aggregated public key. Subsequently, using the same decryption approach as BF IBE, once at least at threshold of validators have release their key share, any messages encrypted for $\hat{Q}$ can be decrypted.

    Implementation Detailsโ€‹

    Since all of this functionality should happen outside the context of a runtime, we implement this as a specialized light client based on smoldot.

    Slot Schedulingโ€‹

    As mentioned above, the idea is that we can take some arbitrary time in the future, $t_{fut}$, and identify a slot and epoch when that future time is expected to occur (assuming persistent liveness of the network). Very roughly, our approach will be similar to the following:

    If we assume that the current slot index is $sl{prev}$ and the epoch is $e_k$, then we allow slots to be schedule starting from the next slot in the queue, $sl{curr}$. Given that each slot lasts a static amount of time, say $t{slot} \; sec/slot$, we can calculate the slot number $t$ seconds in the future with $sl{fut} = ((t / t_{slot}) \% s) +1$ where $s$ is the number of slots per epoch. We can then identify the slot winner by calculating $A[{fut}\; \% \; |A|]$, and thus the ID. The authority slot assignments will be provided to the user from a light client, with calculations of slot seeds occuring within the SDK.

    Encryption-to-future-slots (EtF)โ€‹

    Assuming that we have found an ID for a future slot $sl_{fut}$, we now want to encrypt for that slot. We will use the Boneh-Franklin IBE scheme to encrypt the message for the slot. We have a basic implementation of the BF IBE schemehere.

    The ciphertext can be stored offchain with a reference to it published on-chain (in a pallet or contract) by calculating its sha256 hash, for example. In the future, we will replace this flavor of encryption with a more elegant solution (e.g. some type of witness encryption).

    Decryptionโ€‹

    When a slot winner's slot is active, they derive a secret key which they then use to seal the block. Additionally, the derived secret key can also be used to decrypt any messages that were encrypted for this slot. When the slot winner publishes a block, it also publishes its newly derived secret key. Offchain decryption will be possible with the BF IBE decryption mechanism.

    Overviewโ€‹

    Common Deliverablesโ€‹

    It should be assumed that, unless specified otherwise, each deliverable also includes proper testing (e.g. deliverable (0c)) and documentation of the item, including manual testing, unit testing, and benchmarking.

    The following items are mandatory for each milestone:

    NumberDeliverableSpecification
    0a.LicenseGPLv3
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish an article/workshop that explains [...] (what was done/achieved as part of the grant). (Content, language and medium should reflect your target audience described above.)

    Additionally, outside the scope of the specified milestones, we also intend to formalize the ideas in this proposal within a whitepaper.

    Milestone 1 โ€” Block Sealsโ€‹

    Goal: Implement the IBE block seal in Aura. We do this by creating a new pallet to facilitate the identity based cryptosystem, as well as modifying the Aura pallet and client code.

    NumberDeliverableSpecification
    1.Substrate module: IBE Pallet/IBC SetupWe create a new pallet responsible for storing parameters needed for the identity based cryptosystem as detailed above. This includes param generation and distribution of the msk to authorities. The outcome of the deliverable is the pallet capable of storing system params for the IBC, including the keygen phase managed by the SessionManager.
    2.Substrate module: Aura PalletWe modify the Aura pallet to be able to calculate epk's for each known session validator. Pubkeys will be calculated on session planning and encoded in runtime storage.
    3.Substrate module: Aura ClientWe modify the Aura client to sign blocks with its secret key generated with the identity based cryptosystem as detailed above. We also modify the signature validation phase of consensus to verify the signature/DLEQ proof. For the sake of ease, the block author will publish its secret along with the block.
    4.Substrate Module: Validator IncentivesWe ensure that validators are rewarded when they participate honestly within the protocol (i.e. publish a secret). We do this by making our token inflationary, where each block author is rewarded in additional tokens when they correctly output a secret.

    Milestone 2 โ€” Encryption to Future Slotsโ€‹

    Goal: We want to enable encryption to future slots, including slot scheduling, encryption, and decryption. The following items also necesitates the development of a basic user interface, which uses the light client and SDK which we develop.

    NumberDeliverableSpecification
    1.Light ClientWe implement a light client (based on smoldot) with the added functionality that it: a. can open connections to specific nodes b. ensure clocks are properly set, otherwise return an error. This is to ensure proper synchronization, so that slot scheduling can be reliable/accurate.
    2User Interface: setupWe introduce a user interface which will act as a testbed for integrations between the light client and the SDK. The user interface will be a React project, will connect to the network via the light client, and will interface with IPFS (for storage and retrieval of ciphertexts). This intention is to integrated both light client and SDK and also to ensure that interactions with the chain function as intended.
    3.SDK: Slot SchedulingWe implement slot scheduling logic to identify a future slot based on some future 'time' and derive its inputs.
    4.SDK: EncryptionUsing the output of the slot scheduler, the user agent will be able to encrypt to a future slot or epoch. Ciphertexts will be stored offchain in IPFS, and we will refer to stored ciphertexts by their CID.
    5.SDK: DecryptionAfter a block is authored for the specified future slot, we can decrypt the secret by fetching the secret published with the block (if encrypted to a slot) or a threshold of published secrets (encrypted to epoch) and using it to decrypt the ciphertext created previously.

    Milestone 3: Putting it all together - Sealed-Bid NFT Auction PoCโ€‹

    Goal: We want to put everything developed thus far into action by developing an application that runs on the EtF network. A simple use case is to create a sealed-bid auction platform, where bids are sealed until a certain slot in the future. This work will include the development of an auction contract along with a user interface. At the end of this milestone, we will have a small testnet hosted on google cloud as well as a dapp for sealed-bid NFT auctions.

    NumberDeliverableSpecification
    1.Smart Contract: Auction ContractWe develop a smart contract (and host it on our blockchain) that enables an on-chain auction where participants can issue a sealed-bid which will unseal at some specific future slot. The sealed bid is stored in the contract.
    2.UI/SDK: Auction InterfaceWe develop an interface based on the testbed created in the previous milestone. This interface will have functionality to make calls to contracts, storage, and the blockchain. We also use this milestone to 'batrtletest' our SDK and resolve any issues that could arise in a real-world use case.
    3.UI + Testnet DeploymentWe deploy validator nodes to google cloud and build our first testnet. We will setup telemetry and monitoring in order to gauge real-time performance. We will also host our UI production build on IPFS and setup proper certs.

    Project Overview ๐Ÿ“„โ€‹

    This application is in response to https://github.com/w3f/General-Grants-Program/blob/master/rfps/staking-rewards-collector-front-end.md

    Overviewโ€‹

    The Staking Rewards Collector requests us to make a front-end UI so that non-technical-background people can utilize the tool in a simple way. As the requested features are quite similar to what we have done recently, We intend to implement the requests from the rfps on https://www.cryptolab.network.

    Project Detailsโ€‹

    We plan to utilize the current Staking Reward webpage (https://www.cryptolab.network/tools/dotSR) on CryptoLab as the design base. However, we will change the data source from our DB to Staking Rewards Collector, retrieving rewards from the subscan because the subscan stores all rewards data.

    • Mockup UI
    1. Staking Reward Dashboard

    image

    See the image above, CryptoLab already have a similar page for users to query their rewards. We are going to enhance the followings

    • Filter as requested
    • Export to CSV or JSON

    image

    The table content would also be re-worked to the Staking Rewards Collector one, mockup as below.

    image

    One thing needs to discuss is that is the Tax column necessary? As it is not an input variable, users cannot enter their rates in their countries. We intend to remove the column from the webpage if you're ok.

    1. Staking Reward Filter

    Upon clicking the filter icon, a dialog would appear and provide the following options as requested. A help button would be in this dialog to give users hints of how to use it.

    image

    • Tech Stack

    Front End: Vue.js

    Back End: Rust, NodeJS

    • Architecture

    Currently, CryptoLab is served on a single VPS, thus the Staking Rewards Collector would be an application on it. When a user want to see the rewards, the website would call an API on the cryptolab-web-backend, and it then spawns a thread to call the Staking Rewards Collector and parse the responses in files. The image below show the concept of architecture of the service.

    image

    The modules in white blocks are what we have now. We plan to call Staking Rewards Collector from the cryptolab-web-backend and parse the json output to respond to the query from the website.

    Ecosystem Fitโ€‹

    The staking-rewards-collector is a tool for gathering staking rewards for given addresses and cross-referencing those with daily price data. It is a handy tool for every validator and nominator in the ecosystem. However, since it currently has a CLI and requires technical knowledge to set up (git, nodejs, yarn). A front-end hosted on a website could help many users reach this tool and enjoy the benefits.

    Ask users to enter the Start Balance is bothersome. To further enhance the Staking Rewards Collector, it is technically possible to auto fill the Start Balance of the start date by recording the block number at 12:00 am each day and then collecting the balances during the block number from Polkascan. However, it requires specific works and would not be included in the planned 3-week duration. We may do it if feedbacks from users are positive.

    Where and how does your project fit into the ecosystem?โ€‹

    Cyclops is an important addition to the Polkadot ecosystem as it addresses a key need for network validators. Validators are a critical part of any blockchain network, and they play a key role in securing the network, validating transactions. However, managing a large number of validators can be a complex and time-consuming task, and there is a need for tools that can help validators to manage their operations more efficiently.

    Cyclops fits into the Polkadot ecosystem as a validator dashboard application that provides a comprehensive and user-friendly interface for validators to manage their operations. The application also provides detailed analytics and insights to help validators make informed decisions about their operations.

    Cyclops complements other tools and services in the Polkadot ecosystem, such as Polkadot-JS, Polkadot telemetry, and Polkadot wallet applications.

    Validator operators

    What need(s) does your project meet?โ€‹

    We meet several critical needs for validators in the Polkadot ecosystem, including:

    Efficient Validator Management: Validator management can be a complex and time-consuming task, especially for validators who are managing a large number of validators. Cyclops provides a user-friendly dashboard that allows validators to easily monitor and manage their validators' performance and income, enabling them to optimize their operations.

    Real-Time Performance Monitoring: The Polkadot network is constantly evolving, and validators need to stay on top of performance metrics to ensure that their validators are operating effectively and efficiently. Cyclops provides real-time data on key performance indicators, enabling validators to quickly identify and address any issues.

    Historical Data Analysis: Historical data analysis is critical for validators who need to understand their validators' performance over time. Cyclops provides historical data and detailed analytics, allowing validators to make informed decisions about their operations.

    Notifications and Alerts: Validators need to stay on top of network events and changes that can impact their validators' performance and income. Cyclops provides notifications and alerts to help validators stay informed about critical events and make informed decisions about their operations.

    Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?โ€‹

    As far as I am aware, there are no similar projects on either Polkadot nor other blockchains. Grafana validator dashboards exist for Ethereum, though do not offer a similar level of insight and income management tools.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    In recent years, with the rapid development of information technology, people's work mode has gradually changed from centralized work to decentralized work. Besides, the spread and prevalence of COVID-19 in recent years get people know the importance of diverse work modes. With this trend, the concept web3 steps out from its previous version web2.

    Currently, most Web3 companies are still working with tools within Web2, such as Telegram, Discord, Google Drive, Enterprise WeChat, DingTalk, Lark, and etc, Which user's information and initiative are limited.

    DAO-entrance is trying to create a safe, efficient, powerful and Web3-based instant collaboration tool, which is a breakthrough. It establishes solid trust relationship among organization members through open and transparent smart contract; it maintain end-to-end encrypted communication, to ensure efficient and confidentiallity; it improves work efficiency with thousands of open-source collaborative tool libraries; it keeps data in safe hands through distributed and decentralized storage.

    DAO-entrance focuses on providing DAO with a comprehensive collaborative tool. The tool will help DAO to set up a core team. After the core team authorized by the community, they can make decisions on the daily affairs of DAO, in order to avoiding endless voting.

    Project Detailsโ€‹

    Our long-term goal is to provide a safe, private, efficient and automated DAO tool for enterprises, blockchains and web3 practitioners, in a multi-stage style in different period, and, in the meantime, to offer communication, consensus, production, settlement and other basic needs of members.

    Currently, we provide not only "ink!"-based DAO smart contract templates, but also substrate-based pallet templates, which support instant integration of all substrate-based blockchains. By compatible with existing DAOs through a non-instrusive way, it allows enterprises and organization to create their own DAOs in a more convenient way.

    At this stage, DAO-entrance will provide a slack-like client which is based on the matrix protocol for instant messaging. Users can log in with a blockchain account. This tool is designed for modern devices and is compatible with devices equipped with Windows/mac/Linux/android/iOS, and provides organization members with a concise and convenient collaboration platform.

    Throughย DAPP rendering engine which is based on flutter, DAO-entrance is compatible with most DAPPs and run at a faster speed. The core business would be materialized by flutter native applications, and DAPPs would be rendered by the dapp engine.

    img

    DAO-entrance Client is a non-intrusive client that supports layer1 blockchain and layer2 smart contracts, and it's dedicated to adapting DAO scenarios. As an initial stage, we build the DAO-entrance chain based on the substrate, and manage the DAO-entrance chain by using DAO. After continuous improvement of the Client, we create DAO-entrance DAO, which is a fully autonomous and decentralized organization. Through our own requirements of DAO-entrance and continuous introduction of other work modes of DAO, we provide substrate pallet and "ink!" smart contracts with a fast DAO solution Polkadot Ecosystem.

    According to business needs, DAO organizations will set up skill groups, called "guilds", and each guild will automatically create public chat channels and Kanbans in DAO-entrance. Users can join a guild based on their own strengths or willings. Members can choose whether to participate in projects or events according to their own strengths and willingness.

    We provide DAO templates the substrate pallet and ink! Smart contracts:

    1. RoadMap management.
    2. Manage DAO share.
    3. Management of core team and guild.
    4. Workflow management (board/task).
    5. Financial management.
    6. Task bounty management.
    7. Hot-swap voting management.
    8. Contribution value and medal management.
    9. Level management.

    Tesseract dApps/Wallet integration native mobile libraries

    Overviewโ€‹

    This is a follow-up grant proposal aiming to reduce the integration barriers of the mobile dApp/Wallet integration protocol built during the previous grant.

    Tesseract dApp/Wallet integration protocol implemented in our previously finished grant provides excellent UX enhancement capabilities to the Polkadot Substrate ecosystem. Its current version allows native mobile applications to request public keys and transaction signatures through seamless integration with any Tesseract-compatible wallet installed on the same smartphone. You can see the Polkadoot dApp interacting with a wallet demo here: https://www.youtube.com/watch?v=0AlDYB3Qglc.

    The version released during the previous grant is an excellent achievement for Tesseract. It is the first step toward implementing Tesseractโ€™s full potential. Ultimately, we aim to make Tesseract a universal go-to dApp/Wallet integration solution capable of handling any scenario using the shortest peer-to-peer communication path. You can read more about it in detail in one of our articles: Why do we need better dApp/Wallet connectors?

    To achieve such an ambitious goal, we need to cover two main areas of improvement:

    1. Allow Tesseract to cover more use cases: add desktop dApps connectivity, ability to work with dApps running in browsers, etc.
    2. Provide the dApp and Wallet developers with a way to integrate Tesseract as easily as it can get.

    Even though covering more use cases ASAP sounds tempting, we believe that the UX improvements Tesseractโ€™s current version brings to the Substrate community already provide enough value by itself to focus on and implement an easy way for the dApps and wallets to integrate Tesseract - a set of native libraries (Swift and Kotlin), that allows using Tesseract no harder than any native library the developers are used to.

    Why are the Tesseract native libraries necessary?โ€‹

    iOS and Android provide their developers with native programming languages, which are the standard for the platforms: Swift and Kotlin, respectively.

    In contrast, Tesseract is built in Rust for its reliability, robustness, and cross-platform nature. While providing a lot of pros, Rust is quite hard and cumbersome to integrate into a mobile app (dApp or Wallet) and requires a lot of knowledge and effort, which is a significant barrier to Tesseract integration.

    To counteract this barrier, we propose to build Swift and Kotlin native libraries that wrap all the complexity of Rust integration under the hood and provide the dApp and Wallet developers with easy and familiar native APIs that require no more effort than any other mobile library.

    This way, we reduce the integration barrier to the minimum, allowing Tesseract to participate in Polkadot/Substrate community without bearing any additional complexity for the developer.

    What about cross-platform mobile apps (React Native, Flutter, etc.)?โ€‹

    Cross-platform mobile frameworks, such as React Native and Flutter, are popular among mobile developers. Providing libraries for these frameworks is definitely planned.

    However, building a library for such a cross-platform framework is done via Swift/Kotlin bridges. This means that to build the APIs for the cross-platform frameworks, we first need to implement Swift/Kotlin Tesseract libraries. Itโ€™s an unavoidable prerequisite.

    We are approaching the infrastructure around Tesseract in stages. Even though we would love to have React Native and Flutter asap, to avoid the grant bloating, we narrowed the scope down to Swift/Kotlin, which provides significant value by itself, allowing non-cross-platform developers to benefit from Tesseract while being a prerequisite step for cross-platform libraries development anyhow. React Native and Flutter are the next step.

    Native Libraries APIsโ€‹

    In total, there are four sets of APIs of Tesseract libraries to work on:

    1. Android dApp side
    2. Android Wallet side
    3. iOS dApp side
    4. iOS Wallet side

    Each of the sides requires several rust libraries to be wrapped:

    1. Tesseract itself
    2. IPC transport
    3. Test protocol
    4. Substrate protocol

    For the sake of simplicity, we will not list all the objects and methods here but rather provide examples of how native mobile developers can use Tesseract.

    We aim to make the APIs as simple as we managed to do in Rust and keep them as similar among the platforms as possible. Even though implementing the bridges is not a trivial process and is a lot of interop code, the librariesโ€™ โ€œfrontendโ€ APIs still can be very easy and intuitive. Letโ€™s jump straight to it.

    dApp Sideโ€‹

    Letโ€™s start with some code examples we have in Rust. Here is how one would initialize Tesseract and request an account from the wallet in Rust on the dApp side:

    let polkadot_wallet_service = Tesseract::new(Arc::new(delegate))
      .transport(TransportIPCAndroid::new(&env, application))
      .service(Substrate::Protocol);


    let account = Arc::clone(&polkadot_wallet_service).get_account(AccountType::Sr25519).await?;

    In iOS, it can look something like this:

    let polkadotWalletService = Tesseract(delegate: delegate)
      .transport(IPCTransportIOS())
      .service(protocol: .polkadot)


    let account = try await polkadotWalletService.getAccount()

    And here is an example for Android:

    val polkadotWalletService = Tesseract(delegate)
      .transport(TransportIPC(application))
      .service(Protocol.Polkadot)

    val account = polkadotWalletService.getAccount().await()

    Wallet Sideโ€‹

    While the dApp APIs are typical for client-side APIs, the wallet-side APIs resemble some service implementation closely (i.e., a web service or an RPC). Here is how it works in Rust (an example is taken from the Developer Wallet):

    let ipc = Transport::default(&env)?;
    let tesseract = Tesseract::new()
      .transport(ipc)
      .service(TestService::new(...))
      .service(SubstrateService:new(...));

    Also, TestService and SubstrateService are classes implementing a certain interface (separate for each) that defines how exactly the wallet should reply to the public key and transaction signature requests. Here are the Rust interface implementations:

    impl tesseract::service::Service for TestService {
      type Protocol = Test;

      fn protocol(&self) -> &Test {
        &Test::Protocol
      }


      fn to_executor(self) -> Box<dyn tesseract::service::Executor + Send + Sync> {
        Box::new(tesseract_protocol_test::service::TestExecutor::from_service(Self))
      }
    }
    #[async_trait]
    impl tesseract_protocol_test::TestService for TestService {
      async fn sign_transaction(self: Arc<Self>, req: &str) -> tesseract::Result<String> {
        //implementation code goes here
      }
    }

    The implementation of the Polkadot Service is going to be fairly similar, just different methods (Polkadot specific):

    #[async_trait]
    impl tesseract_protocol_substrate::SubstrateService for SubstrateService {
      async fn get_account(self: Arc<Self>, account_type: AccountType) -> tesseract::Result<GetAccountResponse> {
        //implementation code goes here
      }

      async fn sign_transaction(self: Arc<Self>, account_type: AccountType, account_path: &str, extrinsic_data: &[u8], extrinsic_metadata: &[u8], extrinsic_types: &[u8]) -> tesseract::Result<Vec<u8>> {
        //implementation code goes here
      }
    }

    Such an API implementation approach is pretty straightforward for both Swift and Kotlin. The initialization is a simple builder pattern, and the Rustโ€™s traits here can be replaced with the protocols and interfaces of Swift and Kotlin 1:1 in this case. We are not providing additional examples here to keep the proposal concise, as we believe they are redundant for the wallet example due to its trivial outer API.

    Feasibilityโ€‹

    All the APIs in the examples are tested to be achievable with the mock objects. The feasibility of creating such bridges was tested while creating the mobile demo applications and the Developer Wallet for the previous grant.

    Future Plansโ€‹

    As mentioned initially, we aim to make Tesseract a universal go-to dApp/Wallet integration solution. We approach the development of Tesseract step-by-step, with each additional step bringing a significant concrete value to the ecosystem.

    The most critical areas we plan to cover are:

    1. Simplifying the integration of Tesseract for various development platforms by providing more and more libraries for various platforms (JS, Flutter, etc.)
    2. Cover more use cases. Due to its robust and flexible core, Tesseract is extremely extendible, allowing us to aim for a universal dApp/Wallet integration solution as the ultimate goal. With its first two implemented connectors (mobile IPC for iOS and Android), Tesseract proves its capabilities to provide first-class seamless integration for mobile dApps. Soon, we will release more connectors (Bluetooth, NFC, QR, etc.), allowing more dApps to benefit from our seamless wallet integration. Desktop, Web, and more kinds of dApps will be provided with a seamless wallet integration in the near future.

    Conclusion โž•โ€‹

    Thanks to the support of the Web3 Foundation, the first version of the Tesseract universal dApp/Wallet integration protocol was built and released successfully. Though, to start providing value to the Polkadot/Substrate community, we need to lower the current technical integration barriers imposed by the fact that Tesseract is built with Rust, which is hard and labor-intensive to integrate into mobile dApps and Wallets. To eliminate this, we propose to build a set of native Swift and Kotlin libraries that wrap Tesseractโ€™s Rust implementation under the hood and provide mobile developers with a straightforward way to integrate Tesseract within minutes, thus significantly improving the UX of mobile dApps within Polkadot/Substrate ecosystem.

    Project Overview ๐Ÿ“„โ€‹

    A Dart implementation of the SCALE (Simple Concatenated Aggregate Little-Endian) Codec. We are building a wallet app called Jadewallet which will support DOT/KSM, this project is a component of it.

    Jadewallet is making a new paradigm of self-custody, which uses multi-party computation (MPC) and threshold signature scheme (TSS) technology. MPC based Threshold Signatures gives clients total autonomy over whose digital assets and multisignature ability with keyless cryptographic security.

    We are building Jadewallet with Flutter, although there are Rust, C++ implementations of the SCALE Codec, we think the Dart implementation is the first choice. And we hope the project will also help the Polkadot developer community.

    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Current proposal is the solution from P2P.org for the problem described in Analytics Website/Data Platformย RFP.

    Overview and Ecosystem Fitโ€‹

    Implementation of the data-driven culture was a huge boosting for web2 which allowed the fin-tech industry to speed up the decision-making and the development of new products, also decrease the financial fraud and provide flexible risk-management.

    Dune analytics success and arising 15+ Dune-like platforms are the evidence that data analysis tools are especially acute for web3 today and the demand for community driven data insights continue to grow.

    P2P.org is one of the biggest validators that is participate in more than 40 POS chains. That is why the need of data, monitoring, performance analysis are the core problems in decision making for us. Weโ€™ve started to develop our data function from using external platforms such as Dune but soon we found out that there is no such platform or platforms that could help with even the most common challenges according to data needs:

    • data covering: no Polkadot data and off-chain data about deFi protocols such as Chainlink;
    • absent of the streaming doesnโ€™t allow to receive the data close-to-real time which makes it unacceptable for pro-reactive tasks such as performance monitoring;
    • threshold for entering analytics: we have high skilled data analyst who can work with any data but for business people it is impossible to get answer about new metric very quick.

    Solving these problem internally we understood that our experience and data insights could be helpful for crypto community, especially in new projects such as new cosmos chains where there are not so many users and the economy has just started to evolve. We can help new project with data-driven shilling and go deeper with data-analysis in the chains that we already covered by existing data platforms.

    According the web3 fund need from RFP Polkadot ecosystem needs:

    • extract on-chain data and transform it to be available for SQL querying by data analysts
    • provide public access through query engine to build data sets on-top of indexed data
    • provide UI interface for building dashboards on-top of data sets to visualize data insights for decision makers

    We saw some teams that already building such solutions for the RFP and want to describe our key features which could provide the best user experience according to our vision:

    • modular architecture allows you
      • to use any indexer such as Subsquid, Subquery or custom indexer (Mbelt in P2P.org case)
      • to use any database as a DWH for storing public data (in current RFP we will use BigQuery as DWH)
      • to customize ETL process for any indexer/DWH solution via Airflow DAGs
      • to customize the solution for real-time data enrichment process via direct streaming to DWH
    • dashboard with sli/slo for data quality of ETL pipeline - we provide transparent and clear data quality metrics to estimate the quality of ETL
    • P2P.org infrastructure (P2P RPC for indexation)

    Potential usersโ€‹

    We define the users of the platform as data people who generates insights from the data to support data-driven base for decision makers. These people have:

    • tech skills to write SQL queries
    • basic statistics to define calculate and estimate metrics for the business
    • expertise of the particular domain (such as NFT, particular deFi)

    Current state of Dune platform (as the Leader of the market) is about 20k users. Dune is focusing on Ethereum data and DeFi in Ethereum ecosystem. Current number of active wallets in Ethereum is 400k. So, we see that current state of the crypto industry demonstrates a high proportion of data-people to all token holders with is 5%.

    We believe that in case of mass adoption we will not see this proportion but we need to involve more people still. Our global vision for this problem is to provide ability to work with the data without SQL knowledge. That is why we develop Kolmo - AI assistant.

    Our concern is that we can first attract users from the Polkadot ecosystem, which hasnโ€™t been covered by the current data-platforms. After that we are going to provide an innovative opportunity to enter in data-driven decisions without SQL skills.

    Free usage

    The only limitation for all users is number of TB for free executing of SQL query. We would be able to charge users for executing more data.

    Project Detailsโ€‹

    We already mentioned modular architecture as key feature of the solution. The next chapter will describe it deeply.

    Modular architecture

    Indexing & ETL module consist of:

    • indexer which is Software to extract the data
    • orchestration service: you can use any source to receive the data from RPC and write it to any DWH

    DWH module is analytical data base which stores all the data and provides public access. It consist of:

    • raw layer which is simply the response from indexer - structured/decoded data from RPC nodes
    • domain layer which is the reports and data-marts that were written by the users. By default we would provide the โ€œstaking domain dataโ€ with the data marts about staking

    UI module consist of forking existing BI tool with the ability:

    • get access to DWH data (both layers)
    • interface to write the query
    • execute the SQL statement
    • save and store SQL statements (provided by users manually) to use it for visualizing
    • BI interface to build charts and dashboards on-top of DWH data

    Tech stack

    • ability to make dashboards public |

    Data schema

    Raw layer (indexerโ€™s data) which is MBELT data scheme described here:ย https://github.com/p2p-org/polkadot-profit-transformer/blob/main/db/000001_init.sql

    The solution comes with the second layer of data which is data marts layer.

    There are two ways to create report based on raw layer:

    • via BI where the query will be store as request to DWH
    • PR with data mart that should be re-calculated every time

    Second option is for popular/the most important reports which are accepted by admin users (p2p.org DWH team).

    Initially the solution will contain reports about staking in Polkadot/Kusama/Evm parachains:

    • active set of validators per epoch
    • stake amount between nominator and validator for every epoch
    • total validator stake per epoch
    • the validator commission for all active validators
    • the public identity of validator
    • the rewards (tokens, rewards points) earned by nominator with particular validator per epoch
    • total rewards (tokens, rewards points) earned by nominator per epoch
    • total rewards (tokens, rewards points) earned by validator per epoch
    • ability to calculate APR/APY on top of this reports

    Data quality

    Polkadot SLI (based on history for internal consumption):

    • Block processing mean time: 1073 msec (min - 238 msec, max- 35 sec)
    • Mean latency between block in RPC node to block in database: ~ 18 ัะตะบ (min - 13 sec, max 99 sec)
    • Blocks processed correctly in first attempt (others are fixed automatically): ~ 99%
    • Staking SLI: 100% (no problems detected)

    Parachains sli:

    • Block processing mean time: 914 msec (min - 81 msec, max- 98 sec)
    • Mean latency between block in RPC node to block in database: ~ 95 ัะตะบ (min - 12 sec, max 240 sec)
    • Blocks processed correctly in first attempt (others are fixed automatically) ~ 96%
    • Staking SLI: 95%

    We also have an SLIย dashboard here, but thresholds used in this dashboard were set by internal team and could be different for final public solution.

    Project Overview ๐Ÿ“„โ€‹

    This grant is for the RFP Social Recovery Wallet

    Overviewโ€‹

    Backgroundโ€‹

    As the RFP mentioned: "managing private keys is a difficult task." The next billion users who will enter Web3 will have a hard time entering without the empowerment of social accounts. The Web3 ecosystem needs Web2 functionality that keeps the underlying system decentralized.

    Most of the current authentication is based on the centralized OAuth and SMTP protocol framework. These protocol frameworks will make the authentication service providers becoming centralized collectors of user Web2-Web3 information (although this is not their intention). This massive collection of user data poses a significant risk of exposing the user's identity and assets, ultimately compromising the security and privacy of Web3.

    Descriptionโ€‹

    DAuth is an improved and adapted version of OAuth for the Web3 ecosystem, providing native privacy and trustless social account access for Wallets, Decentralized Identifiers (DIDs), and Decentralized Applications (DApps).

    Our solutionsโ€‹

    In contrast to OAuth, SMS, and SMTP protocols, which rely on centralized servers and third-party services to verify user identities and send messages, DAuth uses blockchain and ZK technologies to provide a trustless authentication and verifiable profile aggregation that enhances trust, privacy, and security on the Web3. This means that users can authenticate their social accounts without revealing their identities. Moreover, DApps can send Emails and SMS messages to their subscribed users while keeping the user's email addresses and phone numbers private at the same time, giving the users greater control over their personal data and enhancing their privacy.

    Decentralized OAuthโ€‹

    The DAuth adapts the mainstream OAuth service providers such as Google, Github, and Twitter for users to be able to pass the authentication of their social accounts without disclosing any information about it. This is because the whole authentication information is managed by the TEE and then a ZK proof is generated and passed onto the DApp proving that the user has authenticated.

    doauth

    Decentralized Emailโ€‹

    This anonymous mechanism is based on the reconstruction of the SMTP protocol. SMTP allows proxy servers to send emails to a given email address. When the DAuth node gets an email request, the enclave will translate the web3 address to the user's email accordingly, and the enclave will establish an SMTP channel with the email service provider. The key point is that the channel will be encrypted with a TLS handshake between the DAuth Enclave and the email service provider, which will keep the user's email address invisible to the DAuth node.

    Documentationsโ€‹

    • Project overview PPT here
    • Project Docs here

    POCโ€‹

    We have completed a proof-of-concept to verify the feasibility of our solutions here.

    Technology Stackโ€‹

    • DAuth Node: A DAuth Node is the basic unit of DAuth Network. DAuth Network will consist of nodes from several institutions in its early stage. In the future, the number of nodes will gradually expand with the increase in the security and stability of the DAuth Network.
    • Secure Enclave: DAuth Enclave uses Trusted Execution Environment (TEE) technology to handle social account authentication in a anonymous way. That is also the part the ZK technology can't do for now. TEE is hardware technology that is leveraged on each DAuth node. The TEE protects the core data of the users from being tampered with by the DAuth nodes.
    • Zero Knowledge Authentication: Zero-Knowledge Proofs are the best way to handle authentication problems since it keeps information private. DAuth uses zero-knowledge as an identity credential generation for users. However, the current ZK technology can not make social account authentication anonymous so we use TEE technology as an add-on module for anonymity protection and use ZK for credential generation.

    Scopeโ€‹

    There are a lot of tasks involved to get all of these into a product-ready state which is what we are always aiming for, but it'd be too extensive to fit all of the tasks into this one single open grant. Therefore, we have carved out a scope specifically for this grant, followed by the details of the future tasks.

    Grant scope

    • Develop TEE module(written in Rust) that supports basic Google OAuth.
    • Develop TEE module(written in Rust) that supports basic Email auth flow.
    • Develop TEE module that generates proofs for user authentication.
    • Develop off-chain node program(written in Rust) that coordinating with TEE module.
    • Develop on-chain protocol (written in ink! smart contract) that organizes all TEE nodes into a functioning network.
    • Contribute SDKs for dApps and wallets in Polkadot ecosystem, such as Clover and zCloak, so that users in Polkaodt ecosystem can have a trustless and private social login to their Web3 accounts.

    Future development

    • Implement more functions in TEE, such as ZK proof.
    • Accept nodes endorsed by more organizations.
    • Support more authentication methods such as Twitter and Discord.

    Ecosystem Fitโ€‹

    • Generally, their are many wallets in Polkadot ecosystem that planning to provide social login functions in the trend of Account Abstraction and MPC wallet. DAuth will make all the wallets trustless, verifiable, private, and fully decentralized.

By leveraging Substrate's flexible and modular pallet architecture, we can shortcut a lot of the overhead needed to create a chain that has a dynamic collective consensus governance approach for things like AI model weights and other safety measures along with higher level controls for licensing of the entire models, jurisdiction training rules and other multi-territorial controls.

    The project aims to be as open and flexible as possible to integrate with other project with an innovative "bring your own" (BYO) token staking economy (faciliated by Pallets such as Balances, Grandpa, Ink! etc).

    We hope for active engagement from the wider Polkadot developer network once the project is complete or even during its development. We strongly believe that this project holds the potential to transform and advance the entire AI industry.

    Team Motivation: Our team is driven by the urgent need to challenge the dominance of centralised corporates like Facebook, OpenAI, Microsoft, etc, in the field of AI model development. These companies have built powerful models that require significant computing power and data, are not environmentally efficient, limit access to AI capabilities and, potentially, create a safety threat to humankind. We believe that these models could not only be statistically improved if they were decentralised, but also may improve power usage efficiency and reduce safety concerns by being transparently controlled by humankind on-chain, rather than a select number of corporations.

    Our second motivation as Livetree involves a solution for our AI tasks, such as video processing, speech-to-text, facial recognition, scene detection, and content recommendations. We currently solve these challenges using centralised model solutions and would like to transition to a decentralised model. For further demonstrations or information on Livetree, feel free to download the free Livetree app and try speech-to-text or contact us. We will gladly provide instructions on how you can try the AI models within our app and provide the raw AI JSON processing results for object detection, landmark recognition, speech-to-text, and other AI processor outputs.

    We are passionate about decentralisation and see the limitations of centralisation in terms of quality of the models, data ownership, privacy, and safety control. This has fueled our motivation to decentralise these models and create a decentralised federated machine learning module.

    Project Detailsโ€‹

    We have made significant progress in integrating TensorFlow's Federated Machine Learning (FML) library within a decentralized Polkadot Substrate environment. This innovative approach combines the power of decentralized machine learning with the robustness of Polkadot's governance and consensus mechanism. The key objectives of our project can be summarised as follows:

    1. Personal data privacy: Our approach ensures that the model is trained on the local node or device, with only the model inferences synchronised through consensus. This preserves privacy as private data never leaves the device/node, protecting user data and maintaining confidentiality.

    2. Improved model quality: By enabling a diverse set of nodes to contribute to the training process, our decentralized approach allows for a wider range of data inputs. This results in better model insights and intelligence that may surpass current centralised models, leading to more accurate, comprehensive and widely available models.

    3. Safety and governance: The governance of consensus built within the Polkadot Substrate framework enables open collective voting on crucial aspects such as model weights, jurisdictional usage, costs, and model selection. This provides a transparent and secure environment for the future AI collective society to make informed decisions and ensures the safety and reliability of the models.

    Architecture Overviewโ€‹

    Logical Componentsโ€‹

    Logical architectural components

    Data Management: Blockchain-based encrypted data storage system that ensures immutable data storage and securely provides data access via protocols and apis.

    Federated Learning Consensus:Implements federated learning algorithms like Federated Averaging or Secure Aggregation for collaborative model training across distributed nodes.

    Collective Economy: Implements decentralized governance using a collective model, to enable decision-making amongst participants to vote on model updates, protocol changes, network parameters, reputation systems, model licensing, nodes lists and incentive mechanisms to encourage active node participation, discourage malicious behavior, and reward contributors.

    Model Deployment: Model serving frameworks (e.g., TensorFlow Serving, PyTorch Lightning) for deploying trained models for production usage, including monitoring tools and frameworks for tracking model performance, latency, and resource utilisation.

    Client Interface: This component acts as a facade providing a universal interface to the deployed models and other aspects of the system for a range of DevTools, SDKs, and user interfaces.

    Implementationโ€‹

    Data Management: Current implementation uses IPFS, however, as part of the grant we plan to make this modular so other dentralised and, potentially, distributed storage systems (such as HDFS) might be dynamically utilised.

    Federated Learning Consensus: Implements the federated learning process which involves multiple stages:

    1. Client Selection: Selecting a subset of clients or nodes themselves to participate in each round of model training.
    2. Model Distribution: Distributing the initial model or updated model parameters to the selected clients.
    3. Local Model Training: Clients perform model training on their local data using the received model parameters.
    4. Model Aggregation: Aggregating the updated model parameters from the clients to generate a node model update.
    5. Model Update Application: Applying the node model update via consensus to the global model.

    Nodes are rewarded for successfully improving the model. This happens at "Model Update Application" stage whereabouts the global model is segregated into training, testing and results data partitions. The application of the node gradient update should result in the testing partition. If the results when compared to the testing partition prove successful then the node is awarded tokens in order to pay for the required resourcesโ€”processors, memory, storage, and network bandwidth used to perform the federated learning. As part of this grant we will introduce token staking so any Polkadot compatible token can be used enabling the framework to support external token ecomonies.

    Collective Economy: By submitting and voting on proposalsโ€”referendaโ€”the DecentralML community can determine what models should be trained, the thresholds for node rewards per model, clients eligible for training, and other ownership and training specifics. These include but are not limited to jurisdicational licensing fees for model deployment and other safety measures such as weights or algorithms related to the model.

    Model Deployment and Client Interface: The ability to interact with the models and chain will be limited to a simple Javascript/Typescript set of interfaces primarily for model submission, and parameterisation through governance.

    Ecosystem Fitโ€‹

    The team has engaged with core members of the Polkadot team who have shown keen interest in the convergence of federated ML and decentralization. Through active discussions with key technical leads, we have identified immense potential to revolutionise the field of artificial intelligence using the Substrate framework and the Polkadot's developer network. Our goal is to democratise and decentralise AI models development by introducing decentralised federated machine learning, surpassing the capabilities of centralised entities. With privacy protection at the core, industries ranging from healthcare to creator and social networks can benefit from our solution.

    To our knowledge, there are currently two AI-related projects in the Substrate/Polkadot/Kusama ecosystem: DeepBrainChain and BitTensor. DeepBrainChain focuses on decentralised GPU server compute, while BitTensor offers a marketplace for ranked models. DecentralML brings decentralised federated machine learning to the ecosystem, making it an exciting addition to the Polkadot ecosystem.

    Overviewโ€‹

    Milestone 1 โ€” Federated Learning Consensus & Data Management Implementationโ€‹

    NumberDeliverableSpecification
    0a.LicenseAPACHE 2
    0b.DocumentationWe will provide both a Gitbook with basic tutorial and inline documentation of the code that explains how a user can (for example) upload and train a model, this will show how the federated machine learning functionality works.
    0c.Testing and Testing GuideUnit test will comprehensively cover core functions ensuring both functionality and robustness. In the Gitbook, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Data Management ImplementationDecentralML, aims to establish a system of on-chain incentives and charges for the four key parties involved in the model's training and utilization. These parties are defined as:

    i) Model Engineers: These are the data scientists, mathematicians, and computer scientists who develop and refine the models.
    ii) Data Annotators: These users enrich the model by providing labels and annotations.
    iii) Data Contributors: These users enhance the model by adding gradients.
    iv) Clients: These are the licensors of the model who may wish to use the model for commercial, contribution or educational purposes.

    Our initial step in this process involves storing the "Master" model in a decentralized storage system. This DecentralML "PUT" method will be parameterized, allowing for the selection of different storage types (e.g., 1=IPFS, 2=Another storage type). We will abstract the data management to support pluggable data storage implementations and will implement IPFS initially. Note: In the future, we would like to support different decentralised storage types to test for update speed, retrieval and caching (see Decentralised data options for polkadot)

    The "Model Creator" initiates the upload by calling DecentralML methods using the Substrate Python Client library. Initially, uploading the "Master Model" and defining the "Training" parameters. These parameters include but are not limited to the following:
    1. The staked pool payable amount is sent by the "Model Creator" and stored on-chain as either DOT (or relevant compatible coin). These assets will ultimately be used to incentivize Data Contributors, Model Engineers, and Data Annotators.
    2. The percentage of the pool allocated to the Data Contributors, Model Engineers, and Data Annotators.
    3. The charges for Model Engineers to download the model.
    4. The charges for Licensors of the model to download it.

    These DecentralML parameters will be set using the Python client library by the "Model Creator". The method will return a global unique identifier for the model.
    2.Federated Learning ConsensusWe will write the core of rewarding "Data Contributors". Our focus will be on supporting Google's TensorFlow's Federated Learning implementation, given its widespread client support and the substantial commercial funding it has received for development. However, we acknowledge the limitations of this approach, particularly in relation to the ProxyModel approach, and we may consider modifying TensorFlow's core FL libraries in future releases to incorporate the ProxyModel approach. In terms of specific deliverables we plan on developing two DecentralML methods:

    1. defineDataContributors([clientId], [walletaddress]): This method, called by the Model Creator (MC), identifies the "Data Contributors" who are eligible to train the model. The clientId is generated by the TensorFlow FL library. It is the MC's responsibility to manage and develop the relevant Client specific applications using TensorFL client libraries. This method is expected to be called before the "Client Selection" step outlined in the "Implementation > Federated Learning Consensus" section of this application. In this context, DecentralML serves as an auditing and reward mechanism for the Data Contributors.
    2. rewardDataContributors([clientIdArray],[0-1]): This method, also called by the MC, rewards the Client for their data contribution. We anticipate this function being called after step 4, Model Aggregation, once the MC has determined a score (defined as the second parameter, ranging from 0-1). This score represents a percentage of the remaining "Data Contributors Pool" defined during the initial upload of the "Master Model". The method then allocates the assets to the Data Contributors' wallet. The advantage of this approach is that it requires minimal modifications to the TensorFlow FL library. Instead, we focus on rewarding and providing transparency for each set of gradients passed by the client, thereby incentivizing the client to contribute data to the model.

    We will also add additional administrative methods as needed, such as the ability to upload the associated Client gradients and query the allocation on-chain.

    Milestone 2 โ€” Collective Economy and Client Interfaceโ€‹

    NumberDeliverableSpecification
    0a.LicenseAPACHE 2
    0b.DocumentationWe will provide both a Gitbook with basic tutorial and inline documentation of the code that explains how a user can (for example) work with governance and stake against a model and how the client interface works.
    0c.Testing and End-to-end (e2e) Testing GuideComprehensive unit tests to ensure core functionality and robustness of code. Instructions on how to run the tests will be included. End-to-end federated learning test using the MNIST dataset for classification
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.Robust Incentivisation SchemeIn response to the feedback received, we will implement a random role assignment mechanism as part of our example game logic. We also see the value in having some flexibility in role assignments, similar to the VBFL paper. This will be configurable using the strategy pattern, thereby addressing the "game theory" concerns. As in the VBFL paper, at every communication round, each device will be randomly appointed as one of the three roles defined as follows: (1) "Data Contributors" can occasionally take on the role of "machine learning worker," as described in the VBFL paper. (2) The role of "model validator" will be an extension of our existing validation processes. This role will employ advanced validation techniques like k-fold and stratified sampling to ensure the integrity and accuracy of model training. This role can be dynamically assigned as with the "machine leanring worker" and "blockchain miner" roles, adding an extra layer of robustness. (3) The "blockchain miner" role will be responsible for incorporating validated models into the blockchain.
    1.Collective EconomyWe plan to establish governance mechanisms related to the selection and training of models, specifically for Data Annotators and Model Engineers.

    For Model Engineers, we will implement the following logical methods:

    1. listMasterModels: This method returns a report listing the modelGUID, modelName, usageType, usageTypeCost, and costTokenAccept.
    2. getMasterModels(licenseUsage, quantityOfPaymentCoins): This method takes the type of usage and the payable amount for that usage, returning the master model. It operates on an element of trust, with users expected to pay the appropriate amount based on the associated licensing (MIT, Apache, etc. defined on-chain for the model). While we don't anticipate this being a problem for this grant, future releases may include more sophisticated whitelists or permissions.
    3. listModelEngineers(modelGUID): This method returns a list of Model Engineer (ME) wallet addresses approved to call the collectiveApprovesModel method.
    4. modelEngineerUpdate(modelGUID, model, senderWalletAddress): Anyone can send their version of the model, which will be stored on-chain for review and approval. We may add more permissions to this method but the idea is to keep it as open as possible.
    5. listModelEngineerUpdates(modelGUID): This method returns a report listing the senderWalletAddress, model version, block number, and updateID.
    6. collectiveApprovesModel(updateID, collective member or MC sender address, reward percentage:0-1): This method approves the model to replace the "Master" model and awards the Model Engineer a percentage (defined in the parameter 0-1) from the Model Engineer pool.
    7. addCollectiveMember(modelGUID, walletAddress): This method adds collective members to the approval list so updates to the model by MEs can be approved. Future expansions may support issues like jurisdiction, licensing, usage, as well as parameter settings for algorithm selection and more.

    For Data Annotators, we will implement similar logical methods:

    1. uploadDataForAnnotation(image, text, sound, testQuestionnaire:questionText, answerType, questionId, answerPoints:numberPointsRewarded, batchParameters): This method allows collective members to provide data that requires annotation. The solution design records the answer types as columns and the questions as rows, enabling a wide variety of annotation questions to be modelled depending on the model requirement.
    2. getDataAnnotationQuestionnaire(modelGUID): This method returns a list of required data annotations and associated questionnaire information with data types as columns, offering flexibility to build a wide variety of dApps that could harness and offer various rewards to DAs.
    3. submitDataAnnotationForReward(modelGUID, questionId, answer): This method implements a simple validation test for the submitted annotated data, with the potential for more sophisticated game theory algorithms to validate DA submissions in the future.
    4. reportDataAnnotationAwards(modelGUID): This method returns a report of pending and allocated rewards.
    2.Client InterfaceWe will focus on utilising Substrate api-client libraries, particularly the Python library. We won't be developing a user interface for Data Annotators or any other specific targetted party. Instead, our attention will be on integrating a Python library, which could potentially be used with applications like Jupyter Notebooks and other machine learning tools in the future. It's important to note that we anticipate commerical "Clients" will use the 'getMasterModel' method, as outlined in the Collective Economy section above.

    Overviewโ€‹

    Introductionโ€‹

    Well-being engagement is up and rising. With a more health-conscious generation of users, they are wanting to experience health engagement in different areas of their lives. Health Hero, as a digital health engagement company, seeks to grow a well-being focused game API that engages developers with health-related development tools. With more people now working remotely, health engagement has never been more important. Healthcare is a multi-billion dollar industry that still struggles with delivering tools to consumers to engage with their health in their own way. IoT, omnichannel, chatbots, and other interactive interfaces are just a few to mention for the opportunities surrounding the use of Health Hero's Game API.

    Project Detailsโ€‹

    The Health Hero Game API provides the opportunity for developers to build games, apps, and features using well-being data endpoints that are centered around steps and fitness data. The play-to-earn approach of the API endpoints, allows the users to earn points in different areas such as XP (Experience Points), HP (Hero Points), Levels, Life, Star Power, badges, and parcels of land that ultimately rewards the user with digital assets (collectibles/NFTs) that are valued in Polkadot currency and Using State Channels to send out the payouts to users from the treasury based on their authentic health data.

    API specifications of the core functionality

    1. Endpoints will provide the following data:
    2. IoT data: step trackers, to include Google Fit, Apple Health, Garmin, Fitbit, Peloton, Headspace, Calm, and more.
    3. Activity data
    4. Gamification data points such as XP, HP, levels, life, star power
    5. Smart contracts customization based on health data engagement

    Ecosystem Fitโ€‹

    Where and how does your project fit into the ecosystem? / What need(s) does your project meet?

    With the growing need of well-being engagement tools, a major pain point is the lack of shareability, access, and implementation of wellness-related features into games, apps, and other online applications. From the users' perspective, the delivery of gamification and rewards is also poorly present in today's games and apps ecosystems. Not only would the developers be able to create and build apps off of our API, but they will have the tools necessary to create customized smart contracts that will deliver a unique and evolving experience to the users based on their own health engagement within the app or game the developers created. These smart contracts will be used against the minting of personalized collectibles that will evolve with a series of attributes (XP, HP, levels, etc.) which are then translated into earnings (play-to-earn) for the users.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    In this application, the deliverables are the micropayment pallet, the client codes and tutorial document. The micropayment pallet contains all the necessary functions for a user to interact with the blockchain including open channel, close channel, claim micropayments etc. The client codes contains two parts: one is for a user to interact with blockchain, the other is for a user to interact with another user. The micropayment design, use cases as well as detailed examples will be given in the totorial document. In the next phases/applications, we will add Proof of Credit and light node discovery pallets as well as their corresponding client codes.

    M1: Micropayments โ€“ 4 weeksโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DescriptionFor our testnet, we use one-way micropayment protocol. There are 2 parties: Sender (Client) and Receiver (Server). There are 3 steps: Sender opens a channel; sender sends accumulated micropayments to receiver; Receiver closes a channel or the channel closed after expiration. When sending the accumulated micropayments, the sender will sign the following data: (receiver, address, nonce, sessionId, accumulateAmount). Each time a new (sender, receiver) channel is opened, nonce is increased by 1 to avoid replay attack. sessionId represents one unique session inside one channel. When a channel is open/active, it can contain multiple sessions. The receiver can only claim once for each unique (nonce,sessionId) pair.
    0c.Testing GuideThe tests will verify the basic functionalities like opening channels, sending micropayments, claiming payments, and closing channels. 1. Opening channels: verify that sender has enough balance to reserve and the channels are unique; 2. Sending micropayments: verify that receiver info and payment amount is correct, the payment is indeed signed by sender, and sender has enough reserved balance. Verify that micropayments are received in each service period; 3. Claiming payments: Verify that balance transfer is submitted on chain; 4. Closing channels: only receiver can close the channel. Clear any outstanding micropayment balances and free reserved balance of sender.
    0d.Language/FrameworkRust/Substrate
    0e.TutorialAdd tutorial documentation including blockchain setup, client setup. Add code examples to demonstrate the interaction between clients to blockchain, as well as clients to clients.
    1.Channel opensender who opens the channel should reserve enough funds for accumulated micropayments. Channel data structure contains sender, receiver, nonce (to avoid replay attack), expiration time.
    2.Channel closechannel will be closed after expiration time passed. Only the receiver can close the channel before the expiration time. The remaining amount which is not claimed by the receiver will be refunded to sender during close.
    3.Claim paymentsDuring the lifetime of the channel, the receiver can claim accumulated micropayments. The sessionId becomes invalid after claim, and the sender should start using a different sessionId for a different micropayment session.
    4.Client to BlockchainThe client inside a deeper device (light node) can automatically interact with blockchain: open channel (client only), close channel (server only), claim payment (server only), add balance (client only), and close expired channels (client only)
    5.Client to ClientThe client inside a deeper device (light node) can automatically interact with each other: start services, send micropayments, stop services.

    Future Plansโ€‹

    1. Light node discovery. Each deeper device is acting as a light node in deeper layer. There are potential millions of light nodes in p2p network. We need pairing light nodes with unbiased randomness and design discovery mechanism in a decentralized way.
    2. Proof of Credit is a core component in deeper network. We already have built MVP functions for PoC. But there are more work to be done.
    3. Testnet: Build an end to end blockchain system that running deeper devices smoothly.

    DEIP IP Management/Governance Module

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    DEIP builds an IP assets management platform which allows discovering, evaluation, and exchange of IP assets on the blockchain. It can be applied to any type of IP assets. The platform implements registration of IP assets on the blockchain, tokenization of IP assets, and governance of IP assets. With such infrastructure, DEIP becomes a foundation for DeFI and DAO around IP assets. In the future, DEIP will also provide a no-code/low code SDK to build custom Dapps for specific IP assets management cases (patents, art, movies, technologies, etc.).

    Integrationโ€‹

    DEIP is a Polkadot Parachain built on Substrate 2.0 Framework and designed specifically for IP governance, tokenization, and exchange. We see integration with Polkadot ecosystem as an important step towards a truly decentralized way to govern and exhange tokenized IP assets.

    Motivationโ€‹

    DEIP team has been building a solutions for tokenization and exhange of IP assets since 2017. We have a vision of a more innovative world where individuals and companies are able to push their innovations to market faster and with less expenses.

    We see Polkadot as a the best ecosystem for us to join. We believe that our protocol will be useful for other companies in the Polkadot ecosystem and even could drive adoption of both Polkadot and DEIP solutions.

    Project Detailsโ€‹

    DEIP IP Management/Governance (IPMG) Moduleโ€‹

    IPMG is a core module for managing technology assets, and assessment and evaluation of IP assets. It enables a collaborative approach in the creation and governance of IP assets via working groups as DAOs, advanced access control & sharing capabilities with Proof of Share. Furthermore, the IPMG module enables a collaborative assessment and evaluation of IP assets via a Decentralized Assessment System that allows to crowdsource expertise from the network. Working groups are managed as DAOs via specific smart-contracts that create delayed transactions with multi-sig to be executed.

    Within the scope of this grant we will implement a parachain and web-based UI with basic functionality for the management of working groups via DAOs, and governance and registration of IP on the blockchain. Core features to be implemented during this phase:

    • Management of working groups (creation, membership management, decision-making mechanisms (voting));
    • Creation of project(s);
    • Creation of IP asset(s) within a project;
    • Registration of IP asset(s) ownership on the blockchain with certification (a digital certificate that embeds a signature of IP asset creator, creation timestamp and hash of the certified IP asset);
    • Access control (with Proof of Share);
    • Ownership validation tool (a web-based tool used to verify the owner/creator of IP asset and creation timestamp using the provided certification data such as hash of IP asset or certified IP asset file);

    Project Overview ๐Ÿ“„โ€‹

    1. Overviewโ€‹

    Dapps have always been a very important part of any blockchain ecosystem, it is where users can connect and interact with blockchain nodes. Given the complex nature of interacting with Substrate-based blockchains, in order for developers to focus on the business logic, a middle layer between dapps and blockchain nodes to facilitate the connections & interactions is always an essential part of the ecosystem and this is where @polkadot/api comes in.

    @polkadot/api has done a great job in helping applications connect to networks in an easy and effortless way by abstracting away all the complexities of connecting with a Substrate-based blockchain and scale-codec serialization process under the hood. But through development experience, benchmarking and profiling, we found out that @polkadot/api has a relatively high memory consumption, which might not be problematic for dapps that only connect to one or a few networks, but for dapps that need to connect to dozens or even hundreds of networks at the same time, itโ€™s a problem which might create a great impact on the overall user experience (e.g: a wallet app or portfolio app needs to connect to a large number of networks to fetch usersโ€™ balances & assets or to listen to on-chain events).

    • If we enable all 100+ Substrate networks on SubWallet, it could increase the memory consumption to over a GB of RAM.

      subwallet-high-memory-consumption

    • Talisman is having their own solution for connecting to networks and fetching balances effectively without relying on @polkadot/api (@talismn/balances, @talismn/api).

    • We ran a NodeJS script that connects to 100 substrate-based network endpoints to fetch balances for an account using @polkadot/api, and the average memory consumption is over 800MB. More details about the benchmark results could be found here.

    As weโ€™re heading toward a multi-chain future, there will absolutely be more parachains, parathreads or solochains built on Substrate to come, and users might have assets spreading over dozens or hundreds of networks. With that, we do see the need of connecting to a large number of networks at the same time effectively and efficiently, Coong Crafts propose to build delightfuldot, an alternative solution to @polkadot/api to address this issue in contributing to the whole effort of paving the way to a multi-chain future of the Polkadot & Kusama ecosystem.

    2. Project Detailsโ€‹

    2.1. Why does @polkadot/api has a high memory consumption?

    We ran memory profiling for a NodeJS script to connect to Polkadot network to see how much memory @polkadot/api consume during the bootstrapping process (initialization). Below are captures of the results:

    • Result of Allocation sampling profiling via Google Dev Tools

      image

    • Result of Allocation instrumentation on timeline profiling via Google Dev Tools

      image

    From the results, we can see that the memory consumption from Metadata and its type system is relatively high. As we looked into the source code itself, we found out that @polkadot/api has its own types and structure for every piece in the metadata, during the decoding process it will create types for all of the pieces in the metadata hierarchy/structure which result in the lot of Type objects and a big Metadata object (PortableRegistry is a part of the Metadata)

    We tried to build a small proof of concept alternative solution using scale-ts (now subShape) for scale-codec encoding/decoding to do the same functionality and the memory consumption has improved noticeably.

    image

    Going further, instead of connecting to 1 network, this time we tried to connect to 20, 50, and 100 network endpoints to fetch balances for an account using @polkadot/api and our PoC solution for comparison, and as we can see from the benchmark result, the memory consumption of our PoC solution is significantly smaller. More details about the benchmarking could be found in our PoC repository.

    2.2. Design Goals & Approach

    2.2.a. API style similar to @polkadot/api

    @polkadot/api is currently using an easy-to-use and intuitive API style (e.g: api.query.system.account(address) to query account balance, or api.consts.[pallet_name].[constant_name] to access constants of a pallet ...).

    So we decided to use the same API style so that users donโ€™t have to learn new syntax when switching to using delightfuldot and making the migration progress easier.

    2.2.b. Less overhead evaluation

    During the bootstrapping process, @polkadot/api will try to register all possible type definitions (ref1, ref2) and expose all available methods/props after decoding the metadata retrieved from a network (ref). This would help make the API execution faster but at the same time make the bootstrapping process longer and increase the overall memory consumption. Secondly, most of the dapps only use a few APIs and types (e.g: fetching balances, transfer balances or assets ...), so the registration of all of APIs and types would be unnecessary in most cases.

    delightfuldot's approach is to perform API evaluation and execution on the fly, which is at the time an API is called, delightfuldot will check if the API is existed or not, register all necessary types (and cache those types if possible for later usage), execute the API and then handle the response.

    For example, upon calling api.query.system.account('5xxxxx...') to fetching balances for an account, delightfuldot will do the following steps:

    • Check if the pallet named System is existed in the metadata, else throw an error.
    • Check if the storage entry named Account is existed in the pallet System in the metadata, else throw an error.
    • Gather all the necessary information to perform a storage query through an RPC state_getStorage like input types, output type, calculate storage entry hash โ€ฆ
    • Execute RPC state_getStorage with the calculated storage entry hash
    • Decode the response with the output type and return the decoded data.

    Unlike @polkadot/api where the first 2 steps are already done in the bootstrapping process. We believe that our approach would help speed up the bootstrapping process and reduce the overhead memory consumption. We archived this by using a proxy technique, you could find more in detail about it in the PoC repository.

    2.2.c. Caching

    Metadata has always been an important part of any Substrate-based blockchain, itโ€™s where we can find all information about on-chain functionalities (pallets, storage, extrinsics, constants, โ€ฆ), but it takes time to encode the metadata retrieved from networks and take space in the memory to store all of the information after decoding the metadata.

    Since Metadata is only updated through runtime upgrades, so delightfuldot will cache the decoded metadata information in the deviceโ€™s storage (localStorage, IndexedDB, โ€ฆ) and only check to update it on runtime upgrade. This would also help speed up the bootstrapping process and reduce memory consumption since the metadata is now stored on the deviceโ€™s storage.

    One drawback of this approach is that access speed to storage would be a bit slower than to memory, but given the benefits of the approach, we believe the tradeoffs are acceptable.

    2.3. Vision

    We set a vision for delightfuldot to become an essential part of Polkadot & Kusama ecosystem, so dapps can leverage its utilities to connect to and interact with hundreds of networks quickly and smoothly without having to think about memory consumption.

    This proposal is asking for a grant to support the first development phase of delightfuldot for the foundational modules with core functionalities. More details are in the upcoming section.

    2.4. Foundational modules with core functionalities

    This step, we aim to lay out all the necessary foundational pieces of the library and put all of them together to form the core functionalities, including:

    • New type system built on top of scale-ts (now subShape) with less memory consumption while at the same time can easily switch to use @polkadot/api's type system for easy migration from existing dapps.
    • A metadata parser with abilities to decode & encode Metadata using scale-codec. In the scope of this grant, we plan to support the latest version of metadata which is v14.
    • Ability to execute RPCs to a Substrate-based node
      • Each blockchain has its own custom list of supported RPCs, in the scope of this grant we plan to implement the supported RPCs of Polkadot & Kusama networks.
      • Support registering custom RPCs, so developers can easily add custom RPCs for their custom substrate node.
    • Ability to execute Runtime APIs
      • Similar to RPCs, each substrate-based blockchain has its own list of supported Runtime APIs, so in the scope of this grant, we plan to implement the supported Runtime APIs of Polkadot and Kusama networks.
      • Support registering custom Runtime APIs
    • With the format of Metadata V14, on-chain functionalities are exposed through palletโ€™s definitions including palletโ€™s constants, storage entries, extrinsic calls, events & errors. We plan to support abilities to:
      • Inspect palletโ€™s constants (similar to @polkadot/api APIs to inspect constants)
      • Inspect palletโ€™s events & errors (similar to @polkadot/api APIs to inspect events & errors)
      • Execute palletโ€™s storage queries (similar to @polkadot/api APIs to execute storage queries)
      • Sign and submit extrinsics (similar to @polkadot/api APIs to sign & submit extrinsics)

    The work will be focused on building APIs to facilitate interactions with Substrate-based blockchain nodes, therefore we'll leverage existing solutions for creating, managing & signing keys in @polkadot/keyring package as well as other cryptography & utility functions in @polkadot/util-crypto, @polkadot/util.

    2.5. Tech Stacks

    • TypeScript
    • scale-ts (now subShape), rxjs
    • Helpful packages from @polkadot/api, @polkadot/common

    Ecosystem Fitโ€‹

    delightfuldot fits perfectly in the Polkadot & Kusama ecosystems as it provides a solution to a critical issue faced by dApps that need to connect to and interact with hundreds of networks efficiently & effectively. Any dApps (e.g wallet apps, portfolio apps, ...) that need to connect to a large number of networks can benefit from delightfuldot's utilities.

    We as the maintainer of Coong Wallet see that delightfuldot is a stepping stone to the next development phase of Coong Wallet with more & more useful features in which Coong Wallet would need to connect to a large number of Substrate-based networks to fetching & syncing information.

    Aside from @polkadot/api, capi is another project to help craft interactions with Substrate-based blockchain, but at the time of writing this proposal, itโ€™s going through a big restructuring, weโ€™re not sure what would it look like until its shape be more concrete. Overall we donโ€™t see any noticeable projects that are trying to solve the same problems as us.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Cryptocurrency wallets are a highly attractive target for cyberattacks. An attacker that breaks into a wallet gets access to secret keys, thereby gaining full control over the user's funds. Many examples illustrate that hacks of cryptocurrency wallets are one of the major security threats for blockchain users. For example, in the recent security breach of the popular atomic wallet, hackers allegedly stole over $100 M worth of cryptocurrency from users of the atomic wallet.

    The overall goal of this project is to develop a cryptographic library to protect Polkadot wallets against cyberattacks. This will be done via threshold cryptography. Threshold cryptography is an emerging technology that can significantly strengthen the security of cryptocurrency wallets. The main idea is to share the secret key over multiple entities/devices, thereby making it much harder for an attacker to gain control over the userโ€™s funds. There has recently been a lot of interest in academia and industry in designing new threshold cryptographic schemes that come with additional security features and offer better efficiency [1,2,3]. Some of these schemes (or variants thereof) are currently deployed in both custodial and shared custodial wallets (e.g., Fireblocks or ZenGo). Most research and implementation of threshold signatures focus on the ECDSA signature scheme. This is because ECDSA is widely used by the two largest cryptocurrencies Bitcoin and Ethereum. In our project, we will focus on the Schnorr signature scheme, which is the main signature scheme used by the Polkadot ecosystem.

    Concretely, we will develop a library that allows to thresholdize BIP32 wallets. BIP32 is a wallet standard that is widely deployed in practice and offers deterministic and hierarchical key derivation. Members of our team have previously designed a threshold BIP32 protocol for the ECDSA signature scheme [4]. In the first phase of this multi-phase grant, we will adapt our threshold BIP32 scheme for Schnorr signatures that are used by Polkadot (i.e., the Schnorrkel/Ristretto). We will summarize our results as white paper that will include a full technical description of our scheme and a rigorous security analysis. We will also give advice on implementing our scheme to avoid common security incidents (e.g., missing range checks or zero knowledge proofs). Finally, we will disseminate our results via a medium article and if suitable through a publication at an academic conference (e.g., Financial Crypto, ACM CCS,...).

    Over the past years, our group has carried out intensive research on threshold cryptography and cryptographic wallets [4,5,6]. With this project, we hope to see some of our research deployed and integrated in practice. Threshold cryptography has many fascinating applications for blockchain systems, and we hope that with this project we can contribute to this emerging field. We choose to focus on thresholdizing cryptographic wallets for two reasons. First, most of our prior research has been on this topic. Second, cryptographic wallets are a fundamental building block that is crucial for any blockchain application (DeFi, staking, gaming,...). Moreover, we have previously talked to researchers at web3/Polkadot, who encouraged us to apply for a grant on this topic.

    Project Detailsโ€‹

    As mentioned above, in this grant we will research threshold cryptographic wallets. We will not develop code at this stage of the project (see the section on Future plans for more details on this), but instead deliver a white paper describing our new cryptographic scheme (including its formal security analysis). Moreover, this white paper will contain a specification that will be a solid basis to enable developers implementing our wallet scheme. Our research in this proposal is mainly based on our prior work on the ECDSA BIP32 wallets [4,5,6]. Let us briefly describe our prior work relevant to this project below.

    In [5,6], we provide the first rigorous security analysis of the BIP32 standard. BIP32 has two main features. First, it offers a deterministic key derivation, where session secret keys are derived via an additive key derivation function from a master secret key. Second, BIP32 offers support for key hierarchies, which are particularly important for larger organizations managing cryptocurrency funds. Hierarchical key derivation also offers two types of wallets: hardened and non-hardened nodes. Hardened nodes offer better security as corrupting the secret keys assigned to such nodes does not affect the security of other nodes in this key hierarchy. The figure below gives a graphical representation of a BIP32 hierarchical wallet.

    bip32-hierarchical-wallets

    In our research work published at the academic conference ACM CCS 2021, we propose a formal security model for hierarchical deterministic wallets. We define two security properties called wallet unforgeability and wallet unlinkability. The first says that funds cannot be stolen as long as the secret keys remain secure. We also integrate hardened node corruption, where the attacker is allowed to learn the secret keys assigned to a hardened node of its choice. The unlinkability property is a privacy feature and guarantees that individual wallets derived from the same master key are unlinkable. Finally, we show that the BIP32 standard satisfies wallet unforgeability and unlinkability. The analysis in our prior work [4] only shows these security features for the ECDSA signature scheme. For further details on BIP32, we refer to the description in our paper [6].

    The second work that is relevant for this grant application is our work on thresholdizing BIP32 [4]. We propose a cryptographic protocol for thresholidzing the ECDSA BIP32 wallet. We also give a security model and formally analyze the security of our cryptographic scheme within this model. A key insight of our work is that by slightly adjusting the BIP32 standard, we can offer significantly better efficiency. To this end, we rely on a threshold verifiable random function (TVRF) and show that for an appropriately chosen TVRF, we can seamlessly integrate it with an ECDSA threshold signature scheme.

    At a high level, this project will combine the results from [4] and extend them to work with the Schnorr signature scheme used within the Polkadot ecosystem. Our work consists of a theoretical and more applied component. On the more conceptual/theoretical side, we will select an appropriate threshold scheme for Schnorr that is compatible with the Schnorrkel/Ristretto environment and offers overall good efficiency. We will design the protocols for threshold Schnorr BIP32. Moreover, we will investigate if our threshold TVRF idea from [4] can also be applied for Schnorr signatures. If this is not the case, we will seek alternatives (e.g., using efficient multiparty computation to evaluate the hash function of BIP32). Finally, we will deliver a security argument for our scheme following the approach from our prior research. On the more applied side, our white paper will contain a specification for developers (with background in cryptography) to implement the key components of our proposal. We provide more details on the tasks carried out in this project as part of the development roadmap.

    Ecosystem Fitโ€‹

    There is a large number of wallets supporting the Polkadot/Kusama ecosystem. While there exist general purpose wallets such as ZenGo that use threshold cryptography to secure funds, there is a large number of Polkadot/Kusama specific wallets that currently do not offer their users support for threshold cryptography (e.g., PolkaWallet). With threshold cryptography, our project meets the urgent need to offer better security to every user in the Polkadot/Kusama ecosystem. This is achieved without inducing additional blockchain fees as unlike multisignatures, threshold signatures produce standard Schnorr/ECDSA signatures that can be verified against a single public key. The results of the first phase of this project can be used by developers to integrate threshold cryptography in their products/wallets. Moreover, it forms the basis for our own software library that we could implement in a follow-up grant.

    As mentioned above, there are multiple projects that build general purpose wallets leveraging threshold cryptography (e.g. ZenGo or Coinbase as a distributed custodial wallet). We are not aware of any Substrate / Polkadot / Kusama dedicated project that works on threshold wallets. Moreover, even existing solutions in the wider blockchain ecosystem will not offer the features that we aim to achieve in this project since our work is based on recent research from members of our team. In particular, except for our own prior work [4], we are not aware of any threshold BIP32 scheme โ€“ in particular, there currently does not exist any variant that is compatible with the Schnorr signature scheme.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    • Total Estimated Duration: 7.25 months
    • Full-Time Equivalent (FTE): 1.25 FTE
    • Total Costs: 87,000 USD

    This is mostly a basic research project and hence a detailed development plan is difficult to give. We will make all results publicly available through a whitepaper that we plan to publish on an archive (e.g., the cryptology eprint archive or arxiv.org). Moreover, if suitable, we will publish the results of our research (or parts of it) via a publication at an academic conference (e.g., Financial Crypto or ACM AFT). We will further disseminate the results of our project via a medium article on our webpage (https://medium.com/perunnetwork). This article will be less technical and highlight our main findings for a broader audience.

    Based on our previous experience with publicly funded research projects, we plan the following main tasks and milestones. Notice that the description slightly deviates from the application template as it is not planned to deliver code in this project.

    1.0b.Documentation/TutorialAs we do not plan on delivering code we will not provide documentation in that sense. The delivered report at the end of this milestone will serve as documentation.
    1.0c.MethodologyThis milestone will be achieved mainly by compiling and reading relevant literature as well as internal talks and discussions. We may involve interviews with external parties such as web3 researchers and/or wallet developers, specifally for Task 1.2. Our results can be verified through the report delivered in this milestone.
    1.0d.InfrastructureWe expect that all our work and deliverables for this milestone can be reviewed and understood without need for specific infrastructure or software except from a web browser.
    1.0e.ArticleWe will deliver a short report that contains a list of academic papers that we studied and a discussion on which cryptographic schemes are most suitable for our goal of building Threshold BIP32 wallets for Schnorr. The report will contain the results from Tasks 1.1 to 1.3. The report is mainly for internal use and hence will be approx. 2 pages. We will make sure that the report is easiliy accessible to the reviewers and the community.
    1.1.Investigation into threshold Schnorr protocolsWe will investigate the current state of the art in threshold Schnorr protocols that are suitable to work with the Schnorrkel/Ristretto environment. We will evaluate them according to efficiency (round complexity, communication complexity) and security. For the latter, important criteria are: (1) static vs. adaptive corruption, (2) corruption threshold, (3) robustness, (4) cryptographic assumptions and models (e.g., only RO vs. AGM).
    1.2.Identification and prioritization of desirable featuresWe will research and discuss the priority and importance of specific efficiency and security features for our application (wallets). If necessary, we may involve interviews with external parties such as web3 researchers and/or wallet developers.
    1.3.TVRFs for threshold Schnorr walletsWe will investigate if existing protocols for TVRFs are compatible with the threshold Schnorr protocols from Task 1.1. We will classify them according to the criteria mentioned for Task 1.1.

    Milestone 2 โ€“ Design of the basic Threshold BIP32 wallet for Schnorrโ€‹

    • FTE: 1.25 FTE

    2.0c.MethodologyThis milestone will be achieved mainly by reading relevant literature as well as internal research discussions. We will make use of our experience and prior work regarding Threshold BIP32 wallets.
    2.0d.InfrastructureWe expect that all our work and deliverables for this milestone can be reviewed and understood without need for specific infrastructure or software. Access is possible via a web browser.
    2.0e.ArticleWe will deliver a report that contains: (1) a description of the security model and definitions, (2) the pseudocode of the cryptographic scheme from Task 2.2 and (3) a brief discussion on the security of our protocol. The article is still mainly for internal use and will be extended during the next tasks. We will make sure that the report is easiliy accessible to the reviewers and the community.
    2.1.Security ModelWe will develop a security model to rigorously analyze Threshold BIP32 wallets for Schnorr. Most likely, this task will be rather easy as the model will be similar to what we have done in our prior works. We will start to sketch the model and security definitions in our report. These definitions may later be adjusted depending on the final scheme.
    2.2.Protocol DesignWe will design the basic protocol for Threshold BIP32 wallets for Schnorr. We will either base our novel protocol on an existing Schnorr threshold scheme or design a threshold Schnorr scheme that is particularly tailored for our use case. We will give a pseudocode description of the protocol as common in cryptographic research.
    2.3.Protocol EvaluationWe will evaluate our basic protocol with respect to security and efficiency. We will not deliver a full security analysis here as the final protocol may still change during later phases of the project.

    3.0e.ArticleWe will extend our report with: (1) the full specification of the Threshold BIP32 protocol for Schnorr signatures and (2) a discussion on why we decided on a particular threat model (see Task 3.2). The report is still mainly for internal use and will be extended during the next tasks.
    3.1.Efficiency ImprovementsIn this task, we will focus on efficiency improvements. Most importantly, we will explore the combination with a TVRF as done in our work on ECDSA. If feasible, this will significantly reduce communication and computation complexity. We will also investigate if techniques for de-randomizations can be integrated into our wallet scheme.
    3.2.Stronger Security ModelIn this task, we will investigate stronger security models. In particular, our current construction for ECDSA only supports static corruption. We will explore if this can be strengthened to resist active corruptions. We will also explore various choices for the corruption threshold and what impact it has on efficiency. Finally, we want to investigate the pro-active setting as it can be used for key updates (e.g., in case of key loss or when the threshold is adjusted). We will decide which of these extensions will be integrated into the final specification. Our decision is based mainly on efficiency/practicality concerns as well as input from external experts and potential users.

    4.2.Implementation ConsiderationsWe will do research on secure implementations of threshold signature schemes and discuss common pitfalls. There have been multiple incidents in implementations of threshold ECDSA (e.g., missing range checks and validity checks), and we will investigate if similar problems may arise in implementations of our selected threshold Schnorr scheme and our wallet scheme.

    Future Plansโ€‹

    We will promote our research results with companies building and running wallets within the Polkadot ecosystem. Moreover, we plan to continue our work in the following directions:

    • Once the research is completed, we plan to work on the implementation of our cryptographic protocol and offer it as an open source SDK. We hope to fund this via a follow-up grant from the web3 foundation.
    • Based on our SDK, we plan integration projects with wallet providers in the Polkadot / Kusama ecosystem.
    • We also plan to run multiple threshold servers, where users may outsource parts of their key shares to. This will be offered as part of a freemium service, where the basic functionality is provided for free but extensions (e.g., better usability, key recovery features, support of key hierarchies etc.) may be purchased by the user.

    Finally, we believe that our research on threshold Schnorr signatures may have applications outside of wallets, e.g., to secure the consensus protocol of modern blockchains.

    Quadratic Funding Pallet

    • Project Name: Build MolochDAO v1 and v2 on Substrate
    • Team Name: Dora Factory
    • Payment Address: 0xadcba9C5C8c33F7F71600c436F2F2B00bAbc9997

    Project Overviewโ€‹

    MolochDAO is the mostly used venture DAO template so far, hosting major venture & grant DAOs such as MolochDAO, The LAO, and MetaCartel Ventures. This project implements MolochDAO v1 on a Substrate pallet. The goal of this project is to eventually launch a MolochDAO for Polkadot ecosystem grants.

    Overviewโ€‹

    MolochDAO was conceived after the fail of The DAO -- the first pioneering effort to support Ethereum ecosystem projects. After The DAO failed, MolochDAO revived the idea of The DAO but with simplicity and security. The MolochDAO itself is a minimum viable DAO, which implemented a concise set of mechanisms including proposal submission, voting, and ragequit. It has been operating safely for some time, and currently hosting more than $6 Million to support Ethereum ecosystem projects with grants.

    The open-source approach of MolochDAO has encouraged many other efforts. For example, The LAO (https://www.thelao.io/) and MetaCartel Ventures are using Moloch as an infrastructure to build DAO venture funds. Together, they are managing more than $50 Million worth of assets at this moment of writing. DAOhaus, on the other hand, creates a platform to create DAOs based on Moloch. It allows different types of organizations to create Moloch-like DAOs on Ethereum to manage its funds. The Open Law team is also developing a MolochV3 codebase (https://github.com/openlawteam/molochv3-contracts), which aims to break Moloch main contract into smaller smart contracts, and bring modularity to Moloch.

    Currently, there are two mature versions of MolochDAO that are widely accepted -- the MolochDAO v1 and the MolochDAO v2. MolochV2 has some major features on top of MolochV1, including 1) multiple tokens in guild bank; 2) loot and shares; 3) guildkick.

    This project develops a substrate pallet that implmenets MolochDAO v1 and v2, in two separate milestones. The goal of this project is to bring MolochDAO to Substrate and make it available for future DAOs on Polkadot, Kusama, and other parachain ecosystems.

    Dora Factory and DoraHacks team is building tools and infrastructures to incentivize / fund open source blockchain innovation. Therefore, one of the first use cases of a Substrate MolochDAO can be a grant DAO to support open source developer projects that build on Substrate. It is yet another alternative to the current funding schemes.

    Project Detailsโ€‹

    The MolochDAO is an open source project.

    MolochDAO v1 codebase can be found here: https://github.com/MolochVentures/moloch/tree/master/v1_contracts

    The current MolochDAO (V2) codebase can be found here: https://github.com/MolochVentures/moloch

    This project will implement MolochDAO v1 and v2 in two milestones. The first milestone is to create a Substrate pallet that implements MolochV1, and the second milestone is to create a Substrate pallet that implements MolochV2.

    The MolochV1 Substrate pallet will implement features including the following:

    • Guild bank
    • Guild shares
    • Submit a proposal
    • Vote for a proposal
    • Process a proposal
    • Ragequit

    The MolochV2 Substrate pallet will be built on top of MolochV1 and further implement features including the following:

    • Support multiple tokens in guild bank
    • Implement loot
    • Guild kick
    • Ragekick

    In this grant, we will not change the mechanism or logic of the original design of Moloch v1 and v2, because of its simplicity and security. However, we recognize the importance of building Moloch in the Polkadot ecosystem as an incentive mechanism and open source DAO infrastructure that can be used in many use cases.

    With an implementation of Moloch v1 and v2 on Substrate, developers from the whole Polkadot ecosystem can build DAOs or other applications based on the code, such as DAO venture funds, parachain grant programs, clubs, project governance bodies, etc.

    A Substrate implementation of Moloch can allow us to make Moloch more useful. For example, managing cross-chain assets or adding application-level features can be made easier on a Substrate-based Moloch implementation. Therefore, after completion of this grant, we can start to build a more general DAO infrastructure based on the codebase, which could evolve into an open platform for DAOs, and every blockchain based organization can use it to support on-chain governance and open source ventures. However, it will depend on a successful delivery of the current grant.

    Ecosystem Fitโ€‹

    Since quadratic funding is a community driven funding mechanism for early-stage grants, it will introduce a more community-driven method to fund developer community projects in the Polkadot and Kusama ecosystem.

    It's also exciting to implement quadratic funding as an on-chain governance module and add it to Polkadot governance stack.

    MolochDAO is the most important open source DAO template in Ethereum ecosystem at this moment. It supports grant DAOs like MolochDAO and venture DAOs like The LAO and MetaCartel. Because of the simplicity of the Moloch mechanism, it can be extended to more use cases in the future.

    Supporting on-chain governance and open source ventures is an important task in the Polkadot ecosystem. Therefore, an open source MolochDAO will be a useful building block is important.

    Multisig Product on Substrate

    • Project Name: Build A Minimum Viable Functioning Multisig Product on Substrate
    • Team Name: Dora Factory
    • Payment Address: 0xadcba9C5C8c33F7F71600c436F2F2B00bAbc9997

    Project Overviewโ€‹

    Multisig is the mostly used DAO infrastructure so far. In the Ethereum ecosystem, multisig wallets are hosting major DAOs (such as venture DAOs & grant DAOs). This project implements a multisig pallet and a minimum viable functioning multisig product on a Substrate. The goal of this project is to eventually launch a multisig product that is integrated with Dora Factory's testnets and parachain.

    Project Detailsโ€‹

    The MultiSig Substrate product functions include the following:

    • Create wallet by organization
    • Multi-asset management
    • Initiate a transaction in a wallet, sign a transaction, confirm a transaction
    • Switch wallet, manage multiple multisig account at the same time

    There've been a multisig pallet developed by parity. The pallet (https://github.com/paritytech/substrate/tree/master/frame/multisig) is a basic building block for us to build a more complete multisig MVP to meet actual demands of DAOs. We have finished the desgin based on the functions of current pallet, you view it here.We'll implement a frontend MVP which interacts with the pallet to make the multisig work for end users.

    Ecosystem Fitโ€‹

    The Dora Factory team has built the first functioning quadratic funding pallet, a MolochDAO pallet (for both MolochDAO v1 & v2), and a POA local testnet that runs an actual quadratic funding round for Dora Factory ecosystem projects (https://hackerlink.io/grant/dora-factory/).

    In addition to the pallets, the Dora Factory team has also built up the parachain infrastructure with a core pallet that helps organizations register and use future pallets that are available on the Dora Factory parachain.

    Although structures vary in different organizations, funding management is a general demand of all decentralized organizations. Multisig has been proven to be the most general and flexible way of managing funds within a DAO (or any other forms of decentralized organizations / communities), because it introduces minimum procedure requirements of funding management except multi-signature itself. Therefore it is also the best entry point to a wider range of dGov applications.

    Quadratic Funding Pallet

    • Team Name: DoraHacks
    • Payment Address: 0xadcba9C5C8c33F7F71600c436F2F2B00bAbc9997

    Project Overviewโ€‹

    We would like to bring quadratic funding grants to Polkadot and Kusama ecosystem so that there is a way for the community to support early-stage developer projects on Polkadot and Kusama.

    Overviewโ€‹

    Quadratic Funding was proposed in Vitalik Buterin's paper Quadratic Payments https://vitalik.ca/general/2019/12/07/quadratic.html. It's now been proven as an effective way to encourage grass-root innovation from the developer community and a unique mechanism to allow community contributors to directly support early-stage projects. Currently, GitCoin's ETH Grant and HackerLink's BSC Grant are already practicing this idea.

    This project develops a substrate pallet that implements the quadratic funding process. The pallet will be tested on a local substrate node, and a simple frontend interface will be created based on Substrate Frontend Template.

    We are building tools to incentivize open source blockchain development on HackerLink.io/en, and we have already implemented quadratic funding grant. Binance Smart Chain community is running its first quadratic funding grant on HackerLink, and we have seen amazing projects being uploaded since its launch. GitCoin is also doing a good job working with the Ehtereum Foundation to host Ethereum quadratic funding grants.

    This is the first step we want to take to eventually bring quadratic funding grants to Polkadot, Kusama, and all parachains that need it.

    Project Detailsโ€‹

    Any quadratic funding grant will consist of two funding pools -- a community contributors' donation pool and a matching pool donated by ecosystem partners. Community contributors will be able to directly donate to projects they like and complete voting in the same time. The distribution of the matching pool will be determined by quadratic voting results from community contributors. Therefore, all community contributors will have a direct impact on the allocation of the matching pool.

    Here is a detailed explanation of HackerLink quadratic funding (use DOT as example):

    The on-going BSC quadratic funding grant can be accessed here: https://hackerlink.io/en/grant

    A Chinese version to explain Quadratic Funding can be found here: https://matataki.io/p/6113

    Ecosystem Fitโ€‹

    Since quadratic funding is a community driven funding mechanism for early-stage grants, it will introduce a more community-driven method to fund developer community projects in the Polkadot and Kusama ecosystem.

    It's also exciting to implement quadratic funding as an on-chain governance module and add it to Polkadot governance stack.

    Future Plansโ€‹

    After implementation of quadratic funding pallet on Substrate, we will plan a quadratic funding grant as soon as the Kusama Network is available. This effort will be in coordination with the Kusama Council. We will audit the pallet code and the frontend code before launching.

    Eventually, we hope to run KSM and DOT quadratic funding grants on a regular basis, and make it a continuous effort to support and incubate developer projects from the community, by the community. Meanwhile, we want to make the pallet availale as a module for every other parachain to run their own quadratic funding grant.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    This proposal is in response to the following RFP: Analysis Website and Data Platform

    The goal of the Dot-ETL project is to lower the friction required to conduct fine-grained and aggregated analysis of transactions on Polkadot network, via a framework to extract Polkadot transaction-level data to various offline formats: e.g. CSV / delimited, relational, columnar. Furthermore, we intend to develop a framework to ETL Substrate to Google BigQuery, orchestrated via Google Cloud Composer.

    The Polkadot and Kusama ecosystems have nurtured a significant developer community, and hosts a number of well-known parachains spanning a diverse series of domains, including Defi lending / liquidity, DEXs, NFTs, RWAs and securitization, as well as identity and privacy applications. While there has been a great deal of interest in developing on polkadot, there hasn't thus far been a simple means to query and visualize transaction-level data and aggregates.

    Dot-ETL will be similar in functionality to the Ethereum ETL project. In the same way that the ETH-ETL offering Ethereum transaction data as a Public Dataset from Google has helped to establish higher TVL and adoption of the Ethereum network, the goal is that by making PolkaDot transactional data easily accessible without the majority of data engineering tasks that exist in extracting data in usable form from the blockchain will lead to greater development and interest for the protocol by mainstream users of platforms such as Google Cloud. Once data is supported and provided in this format, there are also other potential use cases that can expand adoption of PolkaDot data by the blockchain industry such as easily being able to host Chainlink oracles for this data and provide it in readily available form for a number of different cross-chain applications. The open nature of the google bigquery dataset would allow anyone to query and extract insights from on-chain activity via SQL, or even build visualizations on thedata.

    Upon successful completion of the primary data structures (blocks, extrinsics, events), we plan to provide a framework / pattern to extract extrinsics tailored to specific parachains. We may explore Defi and RWAs in more depth: we believe that providing focus on DeFi activity related to Real World Assets on Google Cloud is the most promising use of public data to attract attention to the ecosystem.

    We also intend to publish guides on how to query and use the dataset (i.e. medium articles, github wikis, gitbook document site). The source code for Dot-ETL will be made public through the Web3 foundation.

    The team has extensive technical background in backend software engineering and machine learning / data science, and domain knowledge in machine learning, financial services (both retail as well as institutional), lending, and quantitative risk management. Our expertise and extensive domain experience, particularly in real world usage of data in Fintech and DeFi, will allow for us to build with adoption and practical use in mind.

    Project Detailsโ€‹

    (Technical Details)

    The Dot-ETL project will utilize prior work on the SubQuery project to index and source block/event/call data on the Polkadot blockchain. The SubQuery project is already able to index and parse block / extrinsic(transaction) / event data on Substrate, persist into a postgres data schema, and serve queries on the data via GraphQL.

    Our ETL framework will consume the indexed data on a managed SubQuery node via GraphQL, and save to Google BigQuery in a format similar to existing blockchain-etl projects. We plan to orchestrate this ETL to BigQuery via the Google Composer offering on GCP as Airflow DAGs, written in Python.

    The design of the ETL will allow for a varied series of output formats. Users of the framework can choose to download the code and run their own copy of the ETL locally against the SubQuery node, or they can utilize the GCP BigQuery offering. We expect most users of the ETL data to utilize the public offering.

    The architecture and process of executing airflow pipelines within GCP composer are fairly well-documented. We expect that the infrastructure / architectural components for Dot-ETL will be similar to standard deployments within GCP composer - we are unlikely to require anything truly bespoke.

    The first milestone of the project will focus around blocks, extrinsics and events in Substrate, and will produce the same base-level tables (blocks, extrinsics, events). Subsequent milestones will propose a means to extract specific extrinsics / events from particular pallets and parachains, with a possible focus on Defi / RWAs. We believe that providing focus on DeFi activity related to Real World Assets on Google Cloud is the most promising use of public data to attract attention to the Polkadot ecosystem.

    We're still investigating the appropriate schema details that will capture data in the most useful /optimal way, but believe that the core tables / schema will be very similar to that of the Ethereum ETL project.

    There are two main components of the project. The first is the configuration of the SubQuery managed node that will index the components of Substrate that we are interested in. The second component is the Airflow DAG that will communicate with the SubQuery node via a GraphQL API. The DAG will write updates to underlying formats. The initial focus will be on writing to BigQuery tables, but the framework should be written such that other providers / database formats can be accommodated. While we may not write drivers / handlers for each provider or database type, the framework will be written in such a way that will allow the community to write specific handlers that can be easily plugged into the existing framework.

    Ecosystem Fitโ€‹

    Questions / Answers on Ecosystem Fit:

    Q: Where and how does your project fit into the ecosystem?

    A: Our aim is to provide a foundational framework and approach to ETLing Substrate data into the GCP BigQuery cloud storage medium (+ other mediums as needed). A robust illustrative example will allow others to build upon / extend the framework, and run and maintain the ETL process for general community use. By transforming into GCP BigQuery, we hope to drastically lower the friction required for anyone to analyze and produce insights on the data (developers, analysts, investors, enthusiasts).

    Q: Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    A: Everyone. By building a framework that will make data available in a way that can be queried via SQL, and in conjunction with a repository of query recipes and articles / guides / docs, we allow anyone with some base-level analysis interest to get up and running quickly. Because transaction-level data will also be available in a standard data query format on Google cloud, it will be possible to create any number of dashboards and visualizations on third-party / cloud-based analytic tools.

    Q: What need(s) does your project meet?

    A: Analysis / Insights - ability for people (all audience types) to query transaction data at any granularity. Putting this data into an approachable format opens the ability for users to create reports, visualizations, monitors and notifications. Better visibility => more engagement / better understanding => stronger community. Most users of data don't have the data engineering skills or capacity to extract data of this form onto a platform like Google Cloud platform, while remaining highly adept at querying, analyzing and modeling this type of data on such a platform. The DOT-ETl project is meant to remove the major data engineering barrier that exists for these individuals to take advantage of the technological offerings Google Cloud platform in working with PolkaDot data.

    Q: Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem? If so, how is your project different? If not, are there similar projects in related ecosystems?

    A: There is already a team that has created substrate-etl on Google BigQuery. However, we believe there is value to creating redundancy by providing a competing approach to the problem. Our approach differs in two ways (technically): (a) use of the SubQuery indexer, whereas the competing team utilized their own indexer (polkaholic), (b) use of google composer / airflow.

    This is phase 3 of Dot Marketplace, which is a general-purpose decentralized marketplace created as a Substrate pallet.

    • Dot Marketplace can be used by any decentralized project to float tasks and invite their community members to execute them for a reward. Its POC was developed during the Polkadot India Buildathon (2021).
    • In the previous phases we have built a decentralised bounty platform and a decentralised court for dispute resolution. More details can be found on the respective grant proposals shared above.

    Project Detailsโ€‹

    The current scope of work involves milestone-based submissions in which a project is divided into multiple configurable milestones(min 1 and max 5) to allow parallel or sequential execution.

    • Each project must have at least one milestone and can have a maximum of five milestones (configurable)
    • Each milestone has its independent bidding system where multiple workers can place their bids
    • The publisher can select a bid as per the requirement and ratings of the worker and other criteria that can be added to a user account.
    • A worker can bid for multiple milestones of a single project based on their expertise.
    • A project reaches completion only if all milestones in the project are completed and approved by the publisher.
    • In our current implementation all milestones are independent, hence they can be completed and approved by the publisher irrespective of the overall project status.
    • Based on the requirements, a publisher can add more milestones to a project even after it is pushed to the market, provided the total number of milestones does not exceed 5 (configurable)
    • Decentralized IPFS Storage for project materials using NFTStorage Provider. Each material will have a unique CID that can be accessed by both Publisher and Worker.
    • Advance Search by task tags, ids & title.
    • The decentralized court implemented in phase 2 is functional for each milestone of a project
    • All of the above features will be updated as a new feature for the existing marketplace pallet. Similarly, the selekatal UI will be updated to showcase the same.
    • A new file server written using the rocket framework will be provided for the integration with IPFS (using NftStorage).

    The current focus is to enhance the existing Substrate pallet and allied code base to get a basic yet functional marketplace up and running.

    Ecosystem Fitโ€‹

    We believe this work could be helpful for any Polkadot parachains/parathreads interested in including a marketplace with on-chain dispute resolution.

    • Almost all parachains/parathreads would find motivation in encouraging their community members to contribute meaningfully to their roadmap. This can be achieved by utilizing a marketplace like Dot Marketplace, where technical, marketing, or governance-centric projects can be published as bounties. And community members are invited to bid for and execute them.
    • A milestone-based submission will enhance the functionality of the marketplace and provide a more comprehensive user experience for both the worker and the publisher.
    • The on-chain court will act as a dispute resolution mechanism between users involved in a project. A set of community members meeting specific criteria get to be a part of the jury for the dispute and cast votes, based on which a decision is reached.
    • To facilitate easier communication between a customer and a worker, a one-to-one chat feature is also created.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    This is phase 2 of Dot Marketplace, which is a general-purpose decentralized marketplace created as a Substrate pallet.

    • Here's a link to the approved grant proposal for the first phase.

    • Dot Marketplace can be used by any decentralized project to float tasks and invite their community members to execute them for a reward. Its POC was developed during the Polkadot India Buildathon (2021).

    • It would be directly integrated into Polkadot JS Apps, where such marketplaces could create bounties and tasks that community members could fulfill.

    • The inspiration for Dot Marketplace emerged from our own needs while building Yoda - a protocol that facilitates decentralized app development leveraging open data. Dot Marketplace would be used to create data, services, and app marketplaces on Yoda, which would motivate us to maintain this project in the long run.

    Project Detailsโ€‹

    The current scope of work involves implementing a decentralized court system to resolve disputes in the marketplace and a chat feature between two users.

    • The court is a functionality that delivers unbiased decisions and is driven by a jury.
    • The jury is the participants already present on the chain
    • The jury is selected based on some criteria
    • The potential jurors are collected from the chain based on their past ratings and whether they have the expertise of the task in question
    • Then the final jurors can nominate themselves to be part of the jury for a specific job after accepting the proposal
    • All court cases are time-bound and are given 3 days (43,000 slots) in total
    • The 3 days are divided into 2 parts:
      • Jury acceptance period (14,400 slots/1 day) - This is the period for the potential jurors to accept the jury duty
      • Voting period (28,800 slots/2 days) - This is the time for the jurors to cast their vote. One juror gets only one vote which can be in favor of the customer or service provider (worker)
    • After concluding, all the jurors who participated in the case get a commission, which is based on the total cost of the entire task.
    • In case of a tie or if no juror votes, the voting is carried out by the super juror, who will cast a vote based on the work submitted.
    • A user can call the court on the unsatisfactory rating provided by either the customer or the worker.

    The flow of the tasking pallet with decentralized court implementation

    Tasking-Court-Flow4 drawio

    Dot Marketplace is being built as a Substrate pallet. It would include boilerplate code that para-chain teams can customize as per their requirements. We believe this project has the potential to transform community participation, engagement, and governance in decentralized projects.

    In continuation to previous work, this milestone involves the creation of an on-chain decentralized court to handle dispute resolution. Being a juror is one of the user incentives that can be achieved thanks to the rating module mentioned in the first phase of dot marketplace. The entire milestone covers the Rust/Substrate code implementation. The court process can be called at any one of the instances mentioned from points 1a to 1c below. The dispute logic is a function which will be called from two extrinsic. The additional dispute function for 1c will cover one case (at the moment- for example, the customer is not closing the task due to some reason. The worker gets the functionality to raise a dispute for this particular case). There can be more cases as such, which can be consumed and utilized for any use case. The functions for jury, which are court summon, dispute resolution time and other helpers, can be configured and managed for each use case.

    Dot Marketplace POC was conceptualised and developed during the Polkadot India hackathon. The roadmap listed below comprises of new features that would help take the POC to a minimum viable product (MVP).

    Development Roadmap๐Ÿ”ฉโ€‹

    The development of Dot Marketplace is already underway. For the custom pallet (tasking) we are:

    1. Using various Substrate provided traits like - Currency, ExistenceRequirement, LockIdentifier, LockableCurrency, ReservableCurrency and few more;
    2. Using the pre-existing pallets like assets, balances and staking;
    3. Implementing custom structs like TaskDetails and TransferDetails. These in turn are used for various functionalities like create_task, bid_task, complete_task and approve_task. A special transfer money function is only initiated once the task cycle gets completed and the escrow funds are released to the worker.

    All the below mentioned milestones are going to be implemented and this application is going to be fully public.

    NOTE: A barebones UI would also be provided as a part of this submission to help the developer experience the functionality

    DOTLY: Revolutionizing Polkadot Account Statistics

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The growth of Polkadot, leading blockchain platform, presents a challenge for users in understanding and tracking their account activities. Existing solutions lack intuitive and engaging tools to present comprehensive statistics, leaving users with limited insights into their impact within the ecosystem.

    DOTLY is an innovative application that addresses this problem head-on. By providing a user-friendly platform with visually captivating and interactive displays, DOTLY transforms Polkadot account statistics into an informative and ingsightful experience. Users gain access to a wide range of statistics, including account overviews, balance and extrinsic histories, badges, and action insights. DOTLY goes beyond numbers by incorporating visually appealing charts.

    With DOTLY's intuitive interface, users can understand their account activities at a glance. DOTLY aims to bridge the gap between account statistics and user accessibility, empowering Polkadot account holders to maximize their potential and contribute to the growth and success of the network.

    Target audience

    DOTLY targets a diverse range of individuals within the Polkadot ecosystem, including existing Polkadot account owners seeking a comprehensive solution to track and understand their on-chain account activities, new users looking for an intuitive onboarding experience, and ecosystem enthusiasts interested in monitoring their involvement with pursuing badges.

    Impact

    • Comprehensive Account Insights: DOTLY offers users comprehensive statistics and insights about their Polkadot accounts, including total transfers, transaction rates, balance summaries, and more. By providing this deep level of visibility, DOTLY enables users to make informed decisions, optimize their engagement, and monitor their progress within the ecosystem.

    • Uniqueness: While there may be block explorers offering Polkadot ecosystem account statistics, such as balance history (and not much else), DOTLY differentiates itself through its focus on user experience, and rich charts/insights.

    Future Plansโ€‹

    Altough DOTLY is initially focused on Polkadot, it offers detailed balance overview on parachains that user has balances. I plan to expand its capabilities to include other networks within the Polkadot ecosystem, such as Kusama and other parachains. Users can change parachain to see their stats in other parachains as well just like parachain explorers. This will allow users to track and analyze their activities across multiple interconnected networks, providing a comprehensive view of their participation in the wider Web3 ecosystem.

    Also I am planning to add quests that incentivize users to perform certain actions. Altough this is done by badges (for now) that are awarded to users, quests are a bit different. For example I can incentivize users to swap in X protocol, or stake in Y protocol, or provide liquidity in Z protocol. This will be a great way to increase user engagement and participation in the Polkadot ecosystem. The rewards for quests can be DOT, KSM, NFTs, etc. and can be provided from respective X, Y, Z protocol/tools. This feature is not included in the proposal since it adds complexity to the project and it will take more time to implement.

    Motivation (An indication of why your team is interested in creating this project.)โ€‹

    We love the way we can materialize our ideas. Our small team consists of game and technology enthusiasts, who work in their leisure time with great dedication, passion and great intrinsic motivation on the project. Everyone inevitably has several hats on, we are developer, graphic designer, project manager, web designer and so on. We try to make up for this deficiency with our great enthusiasm and conviction in our almost daily work for the project.

    We have been working on the World of Mogwais for a long time gaining experience in technology and game design, we were stopped by the limitations of the technology we were using, problems like freezing chains due to hash power spikes or no available storage made our lives hard. Just when we were giving up, we learned about substrate, so we dug into it and started to work on migrating and transforming our project into this new world of 3 sec block times and responsive storage access.

    We differentiate the gamelogic into two parts, base logic which is not heavy computing intense which will run inside the node and intense computing gamelogic for example for a dungeon event, which we plan to outsource with an Off-Chain worker to a trusted computing environment.

    PoC/MVP or other relevant prior work or research on the topicโ€‹

    Our alpha MVP is already running, check out our webpage (https://dotmog.com/).

    A lot of our previous work on the World of Mogwais is being used as PoC for the current project, the game logic we created WoMNetCore is reused where it makes sense or refactored to match better, here an old PoC. We used the CryptoKitties on Substrate as our first crash course into Rust and luckily it had a theme in common with our vision from 2017 old whitepaper.

    Ecosystem Fitโ€‹

    I think currently there are no such projects in the substrate ecosystem, at least we don't know of any. The full game logic is written down in our confluence, but for the sake of this file, we don't copy & paste it into here, but we can add it if necessary.

  • Pursuing for the high performance tps, lower to 2~4 nodes, to run a blockchain application, to get the highest performance
  • Put major computing off-chain
  • Easy and quick query and indexing
  • No assets on it, but credits (asset is transferable, credit is non-transferable)
  • No need for collateral

    • By this way, this solution can be adopted and deployed by EVERY person/organization, and doesn't rely on any public service, we call it self-sovereign like what Web1.0 provides (http protocol, nginx servers, etc).

    There is no need to force users to use a web browser wallet plugin to kick off the beginning of the application. No new concepts need to be mastered, so it's relatively easy to import the internet users into the open web application.

    EightFish is a programming framework whose SDK interface is as simple as a traditional MVC web development framework. A good profit we can get is that this solution keeps programming models as the same as Web2.0 (MVC, CRUD, RESTFUL, GRAPHQL), and easily imports traditional web programmers into Open Web.

    This solution leverages all existing outstanding achievements in the database and distributed computing/storage industry from the internet time begins. We can build our next generation of applications based on these shoulders of giants.

    Data Availabilityโ€‹

    Since the application powered by EightFish has a blockchain network underlying, so the availability problem is the same as a general blockchain.

    First of all, all raw request data from user would be recored in the blocks, one by one. For a newly node joined, it could restore the latest global status of the Substrate on-chain node and the SQL db by rows. If there are too many blocks need to sync, another scheme is to get a snapshot from a trustful node, and catch up the latest blocks from that snapshot point.

    The second, we recommend that store the structured data (model object) into SQL database, and put other data (e.g. blob, picture, file) into a decentralized storage network, like IPFS. User upload the blob to IPFS, get the CID, insert it into the content of the structured data, and upload the structured data to the EightFish powered application to store the content into the SQL database, the id-hash pair index into the Substrate on-chain storage.

    This data separation model seems like the model a Web2 application uses. Model data is stored in the database, and pictures are stored in a public image bed service, the url of the picture will be inserted into the content of the model object. But here, it is for Web3.

    Ecosystem Fitโ€‹

    EightFish itself is a development framework, its users are developers.

    The experience of Web2 MVC framework alike will help import amounts of Web2 developers into Web3 and Substrate dev communities, meanwhile help Web3 developers implement their applications for broader internet users easily and quickly. Indirectly, we hope to attract more end users into Web3, by providing better UX and performance, which rely on the underlying framework. Thus we believe in the more adoption of EightFish, the more adoption of Substrate.

    Right now we don't find similar projects on this direction in the Substrate / Polkadot / Kusama ecosystem, and even in other ecosystems. Because most of other ecosystems are in fact ecosystems of smart contract public blockchains, the projects among them are unlikely going to adopt the appchain approach that Polkadot uses.

    And roughly from the June, 2022, Daogang Tang started to construct the EightFish framework, the framework to implement the theory of Open Web. Till now the five core components have been developed, and need another estimated one or two months to make them work together. So it is the right time to apply for the grant of W3f, and introduce the work we did to the whole substrate community.

    Future Plansโ€‹

    There are several points need to be optimized, including the performance of the finalization of the model index on-chain data submitted from the off-chain wasm worker, maybe we will dive into the Substrate transaction pool to do some work. So the perfection of EightFish is the next stop.

    And on the user level, next step we will port the RustCC forum onto EightFish, compile it into wasm code, and run it on the EightFish/Substrate network, that would be a 4 nodes network. And then we will use EightFish to build its own official website.

    We will spend about 12 months to verify the performance and UE of this forum, find defects of it, and improve the underlying EightFish framework.

    Meanwhile, we will start to promote the adoption of EightFish in our dev community, encourage them to test the EightFish framework, use it to develop some applications.

    After enough verifications, we will promote EightFish to all developers around the world.

    Web3 Labs has developed a closed source commercial blockchain explorer for EVM blockchains named Epirus. It is already in production for some private chains of financial institutions, Chainstack, the Palm Network and Iconโ€™s upcoming ICE network. The acquired knowledge and the existing source code, if applicable, will speed up the delivery of the product.

    Our aspirational vision is to deliver a fully modular system providing a runtime for end-to-end extension bundles to compose your bespoke blockchain explorer instance. Each bundle should include the data model, the API and the UIย  to serve a specific set of functionality available in a Substrate node (e.g. contracts, identity, treasury, etc.) and be installable from a repository. In addition to supporting pre-built pallets, it would serve as a powerful complement for custom pallets. This design could stimulate the evolution of the ecosystem through the open-source community.

    Project Detailsโ€‹

    Architectureโ€‹

    The following diagram shows a high-level overview of the system logical components.

    Epirus Substrate Architecture

    The UI client application (C1) runs in a web browser and connects to a stateless web-accessible remote API through HTTP (C2).

    The API exposes the database entities in an easy to query way using GraphQL (C2).

    The database serves as a data enrichment layer and indexing of Substrate related data entities (i.e. metadata, blocks, extrinsics and events).

    The blockchain data services is a modular event-driven data extraction and transformation pipeline. This design will allow us to scale out the processors and extension modules that compose a data pipeline.

    The Substrate Indexer (C3) loads blocks from genesis to the present block height through a Substrate node RPC API. These blocks are stored in the database, emitted to an event hub, and consumed by the base processors (C4) responsible for extracting additional core entities.

    There is a processor per core data type, e.g. events from chain storage, to extract, transform and load it into the database. Each base processor emits events for its extracted entities.

    The extension modules are data processors with a function-specific processing scope, existing one per supported pallet. The Accounts module (C5) is an extension module to index data related to accounts and balances, while the Contracts module (C6) does the same for contract pallet related data.

    System Componentsโ€‹
    IDNameDescription
    C1Explorer UIThe Substrate Explorer client facing application that uses the Explorer API.
    The Explorer UI client application runs in the end-user web browser and uses the Explorer API (C2) for the rendition of user views.
    A registry of composable display blocks, for the navigation and the views itself will be implemented in order to make it easy to adapt the UI to the different pallets available in the Substrate node.
    C2*Explorer APIStateless GraphQL API to access the underlying database. Supports searching by indexed properties, pagination and sorting of results. We plan to serve it using PostGraphile or Husura.
    The API services can scale out by the usual HTTP load balancing.
    C3*Substrate IndexerLoad blocks from a Substrate node. It is responsible for reaching the most recently finalised block in the chain andย emittingย events on the ingestion of blocks.
    This component is the entry point for the transformation pipeline (C4, C5 and C6).
    C4*Base ProcessorsComponents for indexing and decoding the fundamental Substrate data types, i.e. blocks, extrinsics, events and logs.
    C5Accounts ModuleModule to index accounts and balances information.
    This is a prerequisite for the Contracts module (C6).
    C6Contracts ModuleModule to support the contracts pallet and ink! smart contracts.
    Features:
    • Support of two step contract deployment
    • Detection of contract code uploads and indexing of WASM hashes
    • Detection of contract instantiations and indexing of contract accounts
    • Basic decoding of contract calls, i.e. 4 bytes selector and unnamed parametersIndexing of contract related calls and events

    Notes

    * Depending on the readiness of the existing ecosystem projects for indexing and GraphQL API building, e.g. Substrate Archive, Subsquid or Subquery, could be used to provide the functionality of the API (C2), Substrate Indexer (C3) and Base Processors (C4).

    In any case, we will align the project with existing ecosystem solutions as much as possible.

    User Interfaceโ€‹

    The user interface will be based on the existing Epirus look & feel:

    Epirus Look and Feel

    Technology Stackโ€‹

    Web UI

    • Typescript โ€“ Strongly typed programming language that builds on JavaScript.
    • React / Preact โ€“ JavaScript library for building user interfaces. We will consider using Preact, the fast 3kB alternative to React with the same modern API, to reduce the package size if the bundler tree shaking is not enough.
    • Tailwind CSS โ€“ A utility-first CSS framework packed with classes that can be composed to build any design, directly in your markup.

    Data Processing*

    • Kotlin โ€“ Modern, concise and safe programming language.
    • Quarkus โ€“ Kubernetes native Java stack tailored for OpenJDK HotSpot and GraalVM, crafted from the best of breed Java libraries and standards.
    • GraalVM โ€“ High-performance JDK distribution. It is designed to accelerate the execution of applications written in Java and other JVM languages while also providing runtimes for JavaScript, Ruby, Python, and a number of other popular languages. GraalVMโ€™s polyglot capabilities make it possible to mix multiple programming languages in a single application while eliminating any foreign language call costs.
    • PolkaJ โ€“ Java client library to use and access API of Polkadot based networks.

    * Depending on the maturity of the Substrate JVM ecosystem, we can switch to languages with more mature support for Substrate.

    Web API

    • GraphQL โ€“ Query language for APIs and a runtime for fulfilling those queries with your existing data.
    • PostGraphile โ€“ Builds a powerful, extensible and performant GraphQL API from a PostgreSQL schema.

    Database

    • PostgreSQL โ€“ Powerful open source object-relational database. Provides first-class support for JSON data types.
    • Citus โ€“ PostgreSQL extension that transforms Postgres into a distributed databaseโ€”so you can achieve high performance at any scale.

    Synergies to Explore

    • Substrate Archive โ€“ As a possibility to be evaluated, the Substrate Indexer and Base Processors could be provided by this Substrate blockchain indexing engine.
    • Subsquid โ€“ A query node framework for Substrate-based blockchains. In very simple terms, Subsquid can be thought of as an ETL tool, with a GraphQL server included. It is alpha stage software.
    • Subquery - A framework to define your own APIs to expose blockchain indexed data. It is similar to the Graph Network.

    Ecosystem Fitโ€‹

    Substrate Epirus Explorer, in general, aims to deliver a great user experience while browsing blockchain information. In particular, it will provide extensive support for accessing all the information related to deployed WASM bytecode and its account instances.

    The scope of this grant includes a baseline implementation of the core mechanisms and an elementary information display for contracts and accounts. The user interface will fulfil the minimum requirements for the prospective customers of the system to deliver a meaningful and fully functional baseline.

    Existing Projectsโ€‹

    There are other Substrate based blockchain explorers, notably Subscan and Polkascan. Both are general Web3 explorers, whilst Subscan provides a better user experience, supports some pre-build pallets (i.e. staking, EVM and parachain) and exposes a REST API.

    We believe that a single provider cannot absorb all the UI experiences tailored to the growing number of pallets in the Substrate ecosystem. An open community package registry for this UI experience that exposes the functionality and data related to the pallets would benefit the evolution of the ecosystem. Regarding the API, the REST model imposes a rigid model to access information compared to GraphQL.

    Epirus Substrate Explorer differentiates itself from the present offering in the following key points:

    • Initial focus on smart contracts and ink! with unique and novel features like verification and standards contract identification.
    • Ease of customisation and branding without tech provider lock-in.
    • Aim for end-to-end modularity and extensibility.
    • Aim to avoid duplication and foster synergies leveraging existing projects in the ecosystem, like Subquery or Subsquid.

    Potential Synergiesโ€‹

    These are some projects that could ease the implementation of the proposed system:

    a) Substrate Archive is a project that decouples the indexing engine from the blockchain explorer, making it convenient to index historical blockchain data.

    b) Subsquid is a project targeted at developers aiming to reduce the complexity of fetching and transforming blockchain data and exposing it through a GraphQL API.

    c) Subquery is a project with similar functionality to Subsquid.

    Subquery and Subsquid projects are potential candidates to serve as the indexing backend of Epirus Explorer. However, the indexed data needs to turn into the human-friendly information displayed in the explorer UI, requiring further transformations and data enrichment (e.g. metadata from ABI descriptors, RPC calls for standard contract interfaces, etc.) This data transformation and the user-friendly display are what Epirus Explorer provides.

    Future Plansโ€‹

    The present proposal exists to deliver a minimum viable product implementation of the Substrate Epirus Explorer and a public instance connected to a development network.

    After this delivery, we expect to continue evolving the project and use each increment as feedback to the next phase to adapt the course of action as the problem space unfolds.

    Down below is an illustrative sketch of the phases that could follow.

    • Costs: 75,000 EUR

    Tentative scope:

    • Refinement of core abstractions and modules
    • Next increment of the Contract module
    • Ability to display different contract widgets based on contract metadata or standard implementations; e.g. PSP22 and PSP34
    • Support for branded themes

    Phase 3 - Web-Scale Systemโ€‹

    • Estimated duration: 2 months
    • FTE: 2
    • Costs: 75,000 EUR

    • Ready to support a large number of users and transaction volumes
    • Performance analysis and tuning to cope with high volumes
    • Potentially includes horizontal scalability capabilities, e.g. sharding, batch splitting, distributed processing, etc.
    • Monitoring and scalable deployment infrastructure

    On-Going Supportโ€‹

    Post delivery it is anticipated that an ongoing maintenance and support grant will be required from the Polkadot Treasury in DOT to keep Epirus up to date with the ink! smart contract language and Substrate evolution in general.

    Business and Communityโ€‹

    Web3 Labs is passionate about supporting the wider Web3 community.

    Web3j has been going since 2016, and we have offered a free version of our Epirus Explorer for EVM-based chains since 2019.

    Our commercial model of the Epirus Explorer is a paid per volume and support software as a service. We plan to incorporate the Substrate Epirus Explorer into the offering.

    Based on our experience with Web3j over the years, pure open-source is hard to sustain. We want to ensure that our Epirus service on Substrate chains will serve the community while being a self-sustained revenue-generating product.

    The open-core of the Substrate Epirus Explorer, i.e. any grant funded development, will be available to the community without any financial constraints. Anyone will be able to run and extend its instances of the Explorer for its Substrate-based solutions.

    Additional Informationโ€‹

    In order to support ink! and Substrate, parts of Epirus Explorer could be open-sourced under an Apache 2.0 license following an โ€œopen coreโ€ model. Proprietary components, like EVM modules and chain intelligence, would be available exclusively via Web3 Labs Epirus offerings.

    Details about the existing Epirus offering for EVM chains:

    Additionally, it is worth mentioning that the team already built a composable data browser prototype for Solid PODs and RDF sources in general.

    Metadata Decodingโ€‹

    Currently, Epirus Explorer displays the encoded information for contract interaction messages and events, as shown in the image below.

    Contract Encoded Data Display

    We need to decode these entities to make them informative for a user. We will use the metadata in the .contract file generated during source code verification to decode these messages and events.

    As shown in the sequence diagram below, the decoding process will work as follows:

    Contrat Decode Sequence

    With the decoded data available, the Explorer UI can display contract messages and events with meaningful names and decoded parameters.

    Mock-ups

    This is how we envision the decoded contract data will look like: Contract Decoded Data

    Technology Stackโ€‹

    For the Metadata Registry, we will evaluate srtool for the part of deterministic builds, and we will leverage it if it meets our needs. Source code and metadata files will be stored on the file system and served using NGINX with an optimised configuration. In the future, we can also support decentralised storage layers.

    We plan to use Fastify, a project under OpenJS Foundation, for the web API because of its good performance, default security and smooth developer experience.

    We will continue using the Subsquid framework, Typescript and React.js for the Squid Ink processor and Explorer UI.

    Out of Scopeโ€‹

    In the case of contract metadata being uploaded sometime after instantiation, there will be un-decoded messages and events. A re-indexing process needs to be triggered to decode these entities. Currently, the indexing engine does not support any easy way for re-indexation. We will need to analyse the current system and derive the best solution for this situation. Considering the time and effort required, we have decided to leave this feature for the future.

    Ecosystem Fitโ€‹

    Currently, there is a lack of a Wasm contracts-oriented explorer in the Substrate ecosystem. While general explorers such as Subscan and Polkascan are available, the support for Wasm contracts on these explorers is either limited or non-existent. There is no explorer which verifies Wasm contracts or displays decoded contract messages, two valuable features for users. Epirus Substrate Explorer aims to fill the gap and provide a better user experience when interacting with Wasm contracts on Substrate chains.

    Additionally, the Metadata Registry will also be an independent service providing its capabilities to any explorer, or application, that wishes to access contract metadata and verified source codes. It will be comparable to Sourcify in the Ethereum ecosystem. Such a service does not yet exist in Substrate.

    On top of that, Epirus Substrate Explorer leverages existing solutions, such as SubSquid and srtools, which fosters synergy across the Substrate ecosystem.

    Future Plansโ€‹

    With the baseline implementation of the Metadata Registry complete, there are many enhancements that can be built upon it. One such enhancement is to have different confidence indicators for verified contracts. Using the verification process outlined in the Source Code Verification section, we are only able to verify that the function of the code is the same as the uploaded source code. There is still the possibility for malicious actors to upload a "vandalised" source code with misleading function names and comments. We plan to circumvent this issue by allowing the user to sign the upload with his private key; source code uploaded and signed by the code owner will take prevalence over other uploaded sources. The contract code will also have the "signed by owner" badge, thus adding an additional layer of trust.

    With the verified metadata available, we are able to recognise when a contract is implementing a well-known interface. This will allow Epirus Substrate Explorer, or any other application using the Metadata Registry, to display and group contracts based on the interface that they are implementing. It will be similar to how ERC-20, ERC-721 and ERC-1155 tokens are distinguished in EVM contracts. We plan to support PSP-22 and 34 as standard contract-based token interfaces.

    We also plan to support EVM-compatible contracts in Substrate chains. This phase involves adding capabilities to index and decode messages and events from the EVM pallet.

    Lastly, we aim to improve scalability to handle large volumes of users and contracts. We will potentially switch from the current PostgreSQL to a distributed database such as CockroachDB. We also intend to add monitoring and scalable deployment infrastructure.

    Evanesco Network

    • Team Name: Evanesco Labs
    • Payment Address: 15wQ831BoNnEMEVsfvF4mS5e94QL4RYGTc

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • Evanesco is based on Polkadot ecology, committed to building the next generation of decentralized new privacy financial ecology protocol family in a fair and reliable way. Relying on the underlying secure privacy network, mainstream cross chain adaptation mechanism, powerful privacy transaction engine, it can build a more equitable ecology network of privacy finance.
    • The open, transparent and difficult-to-tamper characteristics of the block chain have accelerated the emergence of modern decentralized finance, but in some fields these characteristics are not suitable for the development of financial activities, such as transaction information of large encrypted currency. Whether it is in the cryptocurrency or the traditional financial field, it is very sensitive to the transfer of large-value assets. The transfer information of top Exchange`s address can even affect the market direction. For both parties, it is more hoped that the key transaction amount can be concealed. The privacy transaction process reduces the impact on the market. We belive that a complete decentralized financial network must has a privacy layer. Users are concerned about income risks and account transaction privacy the most in using any finance-related application. Especially when DeFi leads modern finance, the privacy layer, will be an item of standard configuration.
    • Evanesco's vision is to build the next generation of financial ecology in a fair and reliable way. Based on privacy network and privacy transaction technology, it will be committed to breaking through the protocol stacks of public chains, private transaction and DeFi, breaking the liquidity boundary of encrypted assets, and building a robust DeFi operation platform. With the private P2P network, friendly and standardized trading interfaces will be provided for various encryption ecological access, and the privacy transaction liquidity be shared with Polkadot ecosystem, other public chains, exchanges, wallets, OTC, DAO and other encryption ecology.

    Project Detailsโ€‹

    The three main features:

    • Privacy Cascade Network The bottom layer of EVA runs on the privacy layered network, providing development and privacy communication services for the entire network routing layer. Through the construction of a hierarchical decentralized P2P network, EVA combines the open PoW mining network with the privacy trading network, fairly balancing fairness and privacy security.

    • GPoW

      In order to provide a decentralized, more efficient and consistent consensus system for the entire financial ecology, EVA uses GPoW consensus algorithm to perform token mint and final consistency identification. GPoW consensus includes two layers of consensus mechanisms, which are nested, influence each other and play different roles. GPoW algorithm not only provides almost real-time, asynchronous and safe finality similar to GRANDPA algorithm, but also can fairly distribute new tokens according to PoW, enabling a wider range of communities to go in for the construction of the whole ecology.

    • Privacy Transaction

      Evanesco has implemented the balance hiding technology based on Balance account by constructing scope proof, and introduced zero knowledge proof technology into the intelligent contract system, which allows transactions between open accounts and private accounts, and transfer and audit between different accounts. Even if the network miners decrypt the encrypted network layer and view the transaction data Payload, the specific transaction information cannot be decrypted due to the private transaction agreement.

    All the documents are opened in https://github.com/Evanesco-Labs/docs, the docs explain the Evanesco Protocol and associated subsystem, and they will be updated continually.

    Developer can try examples from https://github.com/Evanesco-Labs/xv-crypto/, more demos will be listed soon.

    Ecosystem Fitโ€‹

    Problems such as insufficient liquidity, traceability of transactions and visibility of account book owners during decentralized transactions exist in most standard and non- fungible assets in the current encryption ecology.

    A complete decentralized financial network must has a privacy layer. Users are concerned about income risks and account transaction privacy the most in using any finance-related application. Especially when DeFi leads modern finance, the privacy layer, will be an item of standard configuration.

    Phala Network is privacy preserving data protocol in web3, and it implement Intel-TEE to handle privacy compute. EVA is totally different, it implement the privacy network protocol to protect the user end and a zkp/bulletproof like algorithm to hide the private asset information.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    • Total Estimated Duration: 3 months

    • Full-time equivalent (FTE): 3

    • Total Costs: 1 BTC

    • In the first milestone, the features for the private network protocol will be implemented as a library named P2Private and integrated the API with substrate. After that the substrate node could be deployed like a Tor-network to surpport private communication.

      The private network protocol establishment steps are as follows:

      1. The nodes will establish DHT databases of their adjacent points at the network layer according to the K-bucket algorithm, and set up internal data tunnel routes, which default to 3 hops, in which each node will form routes with other nodes;
      2. After the client or node packages the message, it locates the access point of data tunnel routing through DHT table and sends the transaction to the access point node;
      3. Each data tunnel is established as per TOR protocol.
      4. The tunnel has a re-planning time. If the planning time arrives and data is being transmitted, the tunnel will be re-planned after a period of delay.

    • In the second milestone, we will create a client to communicate with each other based on the testnet setup in the first milestone.

    The following components will be included:

    • Sbstrate Node with P2Private API
    • A Message Client
    • The P2Private library and SDK
    • Tutorial documentation
    • All code written in Rust

We will also expand on this structs on the asset side. The representative can ask for more information in which the user can share it with the representative. The representative will propose a tenant to the letter.
    2.Pallet: paymentsThe renter will have to place a deposit and the monthly rent in. The rent can be credited per x-block basis. The recurring payment can also go in the negative if the renter cannot pay the rent on time, let's say per rule-of-law 14 days and it signals the representative after this time to get in touch.
    2.UI & frond-endDuring the time of development also in previous milestone we will have produced several wire-frames and a front-end frame we will work with. We want to have for each main section page, which are: Funding, Onboarding, Voting, Finalizing and Renting. These will be the most used functionalities. If time allows also a front-end a dashboard that shows the total homes that are on the platformm, the value locked etc. This will be the biggest effort of this milestone.
    2.Total product FSThe combination of the previous milestones and this one, with UI gives us the us the automation the first iteration of the Fair Squares platform that will allow us a crowdfunded fair housing protocol, with an simplified legal acceptance framework.

    Future Plansโ€‹

    Long Termโ€‹

    In 2-4 years from now we aim to co-founded, co-researched a legal framework with other institutions where the outlook for deployment is more clear than now. We are laying strong ties with municipalities or state-level governmental instituions that will allow us the sand-box enviroment to implement this. We aim to organize from the bottom-up with other parties that find this relevant and iterate together with them. But we like to take it step for step and this grant will give us the fundamental code that will showcase it's techincally safe and possible, while recorded right.

    Faterium

    • Team Name: DodoRare, Inc.

    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Faterium is a decentralized voting platform that provides business tools for content creators to monetize their projects and directly engage the community on important decisions. It helps game developers, creators and artists to easily create own assets, distribute them and earn by providing crowdfunding polls on various topics that are important to their community.

    Problem Summaryโ€‹

    Services like Patreon help content creators get support from their community, and Kickstarter helps raise money for a new creative projects. These are very good services and everyone is used to them, but we see opportunity here: the community canโ€™t directly influence the creation process and be truly involved into it.

    Solution Summaryโ€‹

    We have found a solution that can give creators new opportunities to monetize their project and directly involve their community in the creation process through regular voting and events with valuable rewards.

    We will provide a simple interface where creators can create special polls in a few clicks, set which currency will be used for voting, and then invite the community to participate in it.

    Also, we will make convenient tools for creating, distributing and integrating of own assets and NFTs, thanks to which people who are not familiar with Web3 will be able to use the power of decentralization in their projects such as games, online books, movies and comics.

    We integrate social elements into the platform, such as rating, discussion forums or community-created proposals. And it will give creators even more ways to interact with the community.

    In addition, we will make SDKs and APIs to help integrate our platform into existing services and projects, such as games, websites for reading books or comics, or websites for watching movies, which will open up endless possibilities for adopting the technology.

    Glossaryโ€‹

    • User Profile - a collection of settings and information associated with a user.
    • Community - a customizable space where polls, discussions, and events of a specific community will be located, it can be either a personal space or a project space.
    • Crowdfunding Polls - a way for creators to decide what community wants and raise money for a project or idea. Authors themselves determine which currency they want to use for voting and what percentage they will receive after the end of the poll.
    • Poll Rewards - any kind of reward that users can receive after winning the poll. It can be either a unique NFTs or any gifts personally from the author of the poll.

    Usecasesโ€‹

    The Faterium platform can be useful for a large pool of content creators and projects. Such as game developers, comic and manga artists, book writers, movie and anime creators, bloggers and streamers, journalists and politicians, etc. Faterium can be used in all areas where the creators would like to give the community the tools to vote and influence. Now, we would like to show a couple of interesting use cases of the platform.

    Simplified user flow diagramโ€‹

    image

    Comics Creatorโ€‹

    Imagine talented comics creator - Bob Johnson, that has several popular multi-series comics and thousands of fans waiting for new chapters. Bob is looking for a new way to get funding for his projects, and at the same time get feedback from his community.

    He comes to the Faterium platform, configures user profile and creates his first crowdfunding poll, in less than 30 minutes. Bob sets the duration of the poll to 3 days, selects DOT as the voting currency and also sets what will happen after the poll ends - 50% of winners assets go to the poll creator, and winners will receive remaining 50% of assets alongside unique NFTs as reward.

    In the poll, he asks his community a question: "Which comic should I develop this month?". Also, Bob describes options in the poll and give detailed information about what he will do after the end of the poll. Then he posts the poll with unique link in his social media. Fans are happy that the author is preparing new series of comics and they decide to help him by voting. They log in via the polkadot{.js} extension, choose one of the options in the poll and send assets.

    After the end of the poll, the Bob receives finances that will help him to create new series. At the same time, fans took part in an important decision and supported their favorite author, and of course were rewarded with rare NFTs! Looks nice!

    Game Developerโ€‹

    Let's look at another example - a famous game developer. The developer wants to launch the game on as many platforms as possible, so he needs to integrate cryptocurrency into the game in a soft way. Also, he wants to do something unique and increase the involvement of his community.

    He chooses to use the Faterium platform, configures user profile and creates a community on the platform. Since his game has a very interesting plot and characters, he decides to create an asset for each key character in the game. Thanks to a user-friendly interface, he mints new assets in a short time. Then, with the help of the Faterium SDK, he adds these assets to the game as special rewards for players and announce the new feature on his social media.

    Then, he releases new story missions in the game, and players who have assets of their favorite characters, now can directly influence on how the game's story develops by spending assets and voting on various plot twists and character decisions. Players who love the story of the game now have cool tools to interact and influence the game, and last but not least, they can freely sell and buy these assets on decentralized marketplaces.

    It is important to note that game developers who already have own tokens or assets may not create a new one, but use an existing one by bridging it to the Faterium platform.

    Ecosystem Fitโ€‹

    The main goal of Polkadot is to create a decentralized network where users are in control. Faterium empowers as many people as possible to create safe, fair, universal voting polls on any topic possible. In addition, the Faterium platform will not focus only on its own Substrate Network - our main development goal is to cover as many Web3 networks as possible along with Web2. All this will help attract a lot of people who are not familiar with the crypto, influencers, other projects and games. That's why Polkadot and Faterium are compatible and can help each other make Web3 even more popular.

    • Estimated Duration: 4 weeks
    • FTE: 5
    • Costs: 17,000 USD

    The main goal of the Milestone 1 is to create base functionality for Crowdfunding Polls. To make it possible - we will create Substrate Node that will contain basic template pallets, alongside with Pallet Assets (for creating assets), and Pallet Scheduler (for scheduling polls endings). Also, we will create a new Pallet called Crowdfunding Polls Pallet.

    To minimize storage on chain (as polkassembly and Polkadot do) - we will create a Golang server that will embed IPFS node and PocketBase (or launch nearby in separate docker containers), to create the best User Experience and make it possible to store big media files as IPFS CID in database. To make it simple and straightforward in usage - we will launch test Substrate Network with our pallet on our servers, and create pages for creating Polls, and voting (with help of polkadot{.js} extension).

    Overviewโ€‹

    Sybil-resistant faucet is a generic chat bot based faucet solution that can be used on any existing parachain (substrate-based chain, either pallets or ink! smart contracts).

    • Golang
    • Redis
    • Discord sdk (go)
    • Matrix sdk (go)

    Architectureโ€‹

    architecture

    Configurationโ€‹

    To make the faucet generic, it will store its configuration settings in .env file which will include the following settings:

    • DRIP_CAP - how many tokens to send per request
    • DRIP_DELAY - how often user's can request to drip tokens (in ms)
    • REDIS_ENDPOINT - Redis instance endpoint
    • RPC_ENDPOINT - Substrate node endpoint
    • FAUCET_ACCOUNT_MNEMONIC - mnemonic of faucet's wallet

    Based on addons, it can be credentials for any platform, what will be used, in based version discord/matrix.

    Ecosystem Fitโ€‹

    Many dApps are facing an issue where itโ€™s difficult to onboard new users. Thus, the goal is to simplify the process by making it easier for parachain and dApp developers to spin up their own faucets, and give users free tokens without people exploiting the system. In order to make the system sybil-resistant, centralised solutions like Discord, Matrix and any other chat based platforms, that will uniquely identify users, and enable requesting tokens to the account only once per given time period.

    Some similar projects include:

    The advantages of this project are that similar projects are implemented specifically for one platform, this project will be implemented on the interface, and the platforms (Discord, matrix and etc) will be like addons (classes) that correspond to the interface, which will allow you to easily connect new platforms, do not depend on the implementation of platforms, will allow you to run unlimited number of platforms at the same time.

    That is, to integrate a new platform, you will need to implement an interface, and cybil resist, message processing and other functionality will already work out of the box. Also, the implementation of new functionality requires only a change in one point of code, if this does not affect the interface.

    Language Agnostic Analytics Since DotSight aims to be a combination of presentation and querying layer on top of the higher-level metrics above, it will abstract away the smart contracts implementation details and functionality, i.e., EVM, non-EVM, Vyper, WASM, or others will be supported.

    Ecosystem Fitโ€‹

    As on-chain analysis becomes an increasingly important field, there is a growing need for a platform that enables users to access and query high-quality data easily. Our proposed project is an optimal fit for the Polkadot and Kusama ecosystems. The current options for querying data via GraphQL are limited to backend services such as Subquery and Subsquid; however, our proposed data interface will provide a user- and developer-friendly way to surface customized analytics, similar to Dune Analytics in the Ethereum community; however, with more flexibility, customization, and at a higher level of abstraction.

    Our decentralized platform will enable analysts and power users to interactively query and visualize high-quality data, creating custom charts and visualizations to share metrics with others. By easing the process of building dashboards, sharing data visualizations, and integrating data providers, we will encourage projects to create custom dashboards to share data with the Polkadot & Kusama community.

    Development Status ๐Ÿ“–โ€‹

    The basis for the project has been established. FiDi today offers four default dashboards available for the community (one metric, three metrics, a pie chart, and an asset list) and a fully customizable advanced analytics dashboard currently under development and in open beta with ambassadors and core teams of several parachains. Subquidโ€™s recent release of GiantSquid API makes surfacing metrics and deploying new squids intuitive for developers and L1 operators.

    This proposal aims at delivering (a) a data interface connecting the squidsโ€™ query code and customized dashboards and (b) both streamlining and decentralizing the productionization of new analytics queries for the community by community.

    All infrastructure deliverables belong to the teamsโ€™ domains of expertise and serve as a continuation of our previous track record.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 โ€” Data Interfaceโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide documentation on every supported metrics class and an educational tutorial explaining the typical way to interpret the data, deploy a data interface configuration, and select the desired dashboard.
    0c.TestingCore functions will be fully covered by a unit and integration tests suite to ensure robustness, deployment, and serving times.
    1a.GiantSquid data funnelingWe will extend the existing data streaming infrastructure to support an arbitrary query to GS and user-built squids.
    1b.Data Aggregation moduleWe will provide support for user-specified (GraphQL or SQL) aggregation logic that would be inputed via the data interface and invoked at the streaming stage.
    1c.Off-chain sourced addresses supportWe will provide rudimentary support for additional data materialization parameters, e.g., pricing via liquidity pool addresses. This will be extended to any off-chain data in an oracle-like fashion in future milestones.
    2a.Data Interface for developersWe will provide a configuration-based interface (initially via git pull requests, then automated in Milestone 2) with key specifications for the new views. We will leverage React and Typescript on the frontend and Typescript with Nest and PGSQL on the backend.
    2b.Schema mapping and morphingWe will provide a configuration-based paradigm for specifying: the desired metrics mapping, aggregation logic, upstream GiantSquid URI, and desired materialized view.
    3a.Dashboards: Default Analytical ViewsWe will integrate the default views, i.e., pie chat, 1/3-metrics view, and list of assets, with the data interface and make it available for the ad-hoc developer deployment. For 3a-c UI components, we will similarly rely on React + Typescript.
    3b.Dashboards: Advanced Staking ViewWe will integrate the advanced staking view, e.g., the dApps names, nominator TVLs, balances, rewards, and ranks, with the data interface and make it available for ad-hoc developer deployment.
    4a.Lighthouse use cases: Squids for Wallet-specific metricsWe will implement new squids in GraphQL surfacing wallet-specific metrics for two parachains with the following metrics that need to be surfaced via GiantSquid: Free tokens, Vesting, EVM Deposits, and dApp names.
    4b.Lighthouse use cases: Squids for dApp-specific metricsWe will implement new squids in GraphQL surfacing wallet-specific metrics for two parachains with wallet-specific metrics for dApps: TVL change per dApp, Active (UAW) and net new wallets per dApp (x2), historical Transactions / Volume / Balance per dApp (x3).
    4c.Lighthouse use cases: customized dApp viewsAs the first two use-cases, a feasibility proof and an accelerator, we will provide the community with a fully integrated customized dApp analytics dashboard leveraging the data interface (2a-2c), the advanced staking view (3b), and the data aggregation module (1a-1c).

    Milestone 2 โ€” POC Dashboards with Network-, dApp-level and custom Metricsโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide documentation on every supported metrics class and an educational tutorial explaining the typical way to interpret the data, navigate the developer UI, specify the required metadata, deploy a data interface configuration, and select the desired dashboard.
    0c.TestingCore functions will be fully covered by a unit and integration tests suite to ensure robustness, deployment, and serving times.
    1a.dApp-level signals: collator metricsWe will generalize prior work from Milestone 1 to span collator/nominator activity and make metrics such as uptime, block production rate, block processing time, rank/nominator rank, name, and value locked available in the views. For 1a-2a, the respective GraphQL squid query and GiantSquid's code are also in scope; the UI components will be written in React + Typescript, and the backend code in Typescript + Nest + PGSQL.
    1b.dApp-level signals: user activityAdditionally, the dApp-specific user activity metrics will be surfaced, e.g., UAW, net new wallets, historical transactions, volume, and balance per dApp. Respective squid query and GS code are also in scope.
    2a.Network-level signalsWe will generalize prior work from Milestone 1 to span L1-level metrics and activity made available in the developer UI, e.g., UAW per network, number of new wallets, adoption rates, unstaked tokens currently in wallets, tokens in circulation, and tokens staked or locked. Respective squid query and GS code are also in scope.

    Milestone 3 โ€” Developer UI & Automated View Deploymentโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide documentation on every supported metrics class and an educational tutorial explaining the typical way to interpret the data, navigate the developer UI, specify the required metadata, deploy a data interface configuration, and select the desired dashboard.
    0c.TestingCore functions will be fully covered by a unit and integration tests suite to ensure robustness, deployment, and serving times.
    1a.dApp-level signals: collator metricsWe will provide an intuitive web interface for specifying the desired metrics mapping, aggregation logic, upstream data provider, and desired materialized view (dashboard). The UI willleverage Typescript + React; and Nest + CloudSQL (PGSQL) + Typescript on the backend.
    1b.Online testing & deploymentWe will provide an intuitive web interface for querying the new view for deployment and validating its configuration. The UI's part technology choices is the same as 1a.
    2a.Deployment validation & View statusWe will implement testing and validation layers to ensure the user-inputted configurations for newly spun-up views and queries are performant. We will surface the view โ€œstatus,โ€ e.g., up, down, missing data, and similar.
    2b.Automated and ad-hoc deploymentWe will decouple the existing infrastructure to support ad-hoc and scheduled deployments for newly created views. The CI/CD and automation for 2a-b will rely on scheduled App Engine workers.
    2c.Data interface: view constructionWe will provide developers with the ability to select a desired analytical dashboard from the pre-selected collection (see five views explained in the architecture section; fully customizable views will make it to future milestones). These UI components will also be implemented via React and Typescript.
    2d.Data interface: DeploymentWe will provide developers with the ability to schedule their customer viewโ€™s deployment (automatically at recurring times in the future milestones). The deployment action will be a UI module, and the propagation/consensus will occur via GitHub at first and via a PGSQL query in future milestones.

    Milestone 4 โ€” Interactive SQL Query Engine for Viewsโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide documentation on querying methodology, e.g., functions, operators, data types, and statement reference; as well as an educational tutorial explaining the typical way to run the queries, associate them with the views, interpret the data, navigate the developer UI, and share the views.
    0c.TestingCore functions will be fully covered by a unit and integration tests suite to ensure robustness, deployment, and serving times.
    0e.ArticleWe will publish an announcement article capturing the work completed in the grant along with the educational guides and success stories, enabling users to further leverage and expand DotSightโ€™s functionality.
    1.FiDi SQL implementationWe will provide a query engine for blockchain data. Initially forked from TrinoSQL and/or harmonizer, we will extend the functionality to support variable views and embed GraphQL upstream queries. We'll simialrly rely on Typescript + Nest + CloudSQL (PGSQL) for the query engine's implementation. FiDi SQL Engine UI Example
    2.SQL Editor View UIWe will augment the no-code view developed in Milestone 2 with SQL functionality allowing users to rehash the existing views as well as create new ones. The Editor UI will include the runner log, a tree of dependencies and suggested resources, and the editor interface itself. See the UI direction in the following wireframe:
    3.Advanced Querying DocumentationWe will provide a comprehensive guide for optimizing the queries, both language- and database-specific, along with real-world examples

    Future Plansโ€‹

    DotSight will provide a scalable, incentivized platform for developers to contribute to the Polkadot ecosystem's growth by integrating new protocols and on-chain metrics. We aim to continue extending the number of parachains with advanced analytics supported on FiDi, the breadth and depth of analytical dashboards, and the pre-developed squids available.

    For further development, we will also streamline the user/developer funnel to the point where simple SQL/GraphQL or no-code user flows suffice to seamlessly productionize and share new dashboards matching user needs. For the further go-to-market, we plan to attract content creators and crypto influencers by offering customizable portfolio views, analytical dashboards, and reward-based contributions to extend coverage and analytics on the platform.

    • Payment Address: 3HrP78rbmafpfBsU49LCpywYrNcscnKd76

    The above combination of your GitHub account and payment address will be your unique identifier during the program. Please keep them safe.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Please provide the following:

    • A brief description of the project.

    Fractapp is a messenger with a cryptocurrency wallet. Cryptocurrency address is hard to remember so users have a problem send cryptocurrency to another user. Fractapp creating a simple ecosystem for users. Users can send crypto in chats and use DApp chat-bots. Fractapp will be available on Android and later IOS.

    And we have old DEMO for the hackathon.

    • An indication of how you will integrate this project into Substrate / Polkadot / Kusama.

      The integration will involve creating a mobile app on Expo (React Native) and backend services.

    • Mobile App:

      • Non custodial wallet for Polkadot and Kusama (creating, backup, wallet details, transaction info)
      • Payment chat is a chat for only send cryptocurrency. These milestones haven't support messages in chats. But we will add messages later.
      • Chat-bots for DApp

    • Backend services:

      • Push-Notification service is a service which will notify a user about received transactions
      • Profile service is a service that stores not public information about the user (Nickname, Twitter, Email, Phone Number).

    • CBI (Chat-Bot interface):

    CBI is the interface between Fractapp and your chat-bots. It can be summarized in the following algorithm:

    1. To call the bot, the user must send a request to start.
    2. Bot service must return the user interface (button name, image, and trigger name)
    3. The user clicks a button and sends the request with the trigger name to the chat-bot service.
    4. Chat-bot processes the user's request by the trigger name.. If the user doesn't need to make a choice then the service returns the transaction which the user will sign.
    5. User signs or cancels transactions.

    Example, Decentralized Exchange Bot (exchange DOT <-> KSM):

    1. User sends a request to start.
    2. Chat-Bot returns response with 2 buttons: DOT, KSM
    3. User chooses DOT
    4. Chat-Bot returns the text-editor element to the user
    5. User sends a request with text (amount)
    6. Chat-Bot returns transaction (transaction calling Exchange DApp)
    7. User signs and sends transaction
    • An indication of why your team is interested in creating this project.

    Polkadot is one of the most interesting blockchain platforms. We want to help users to just join in polkadot and wallet is the most important module in the platform.

    Halva is a toolchain for improving the experience of developing Decentralized Applications based on Substrate. It provides a high-level way to configure a development environment, interact with Substrate through external API and writing your test cases.

    Halva inspired by Truffle but implements Substrate specific API. It targets testing extrinsics via RPC calls this allows test Substrate (or clients compatible with Substrate RPC) as a black-box. Halva uses Polkadot.js to interact with RPC.

    Right now you must do much boilerplate code around your testing framework (mocha, chai, ava, etc) so that beginning testing your Substrate based app. Halva addressing these challenges.

    Overviewโ€‹

    Hamster is a decentralized computing network based on the underlying chain. It aims to provide users with cost-effective computing servers. It is a decentralized platform for leasing computing resources that can be performed to rent idle computing resources

    Currently there are many cloud computing service vendors providing cloud computing services, but currently with the expansion of services, the price of cloud computing services is gradually stabilized and high, and most of the cloud computing services are purchased on an annual basis, which causes great waste for current users who may use them for a short period of time, while the world's hardware capacity is gradually increasing today, and people have more and more idle computer products on hand. The goal of our product is to utilize the current idle computing resources in people's hands in a decentralized way, so that users who need it can use computing services in a cost-effective way.

    Our team aims to build a complete platform for leasing idle computing resources. The decentralized computing resource leasing function is realized by using substrate framework pallet, which can be leased and traded on the chain, and the link and use of computing resources can be done through the p2p network protocol under the chain after signing the lease agreement on the chain.

    Project Detailsโ€‹

    Hamster is composed of Hamster nodes, Hamster resource providers, Hamster clients, Hamster gateways, and Hamster front-end pages.

    • Hamster Node: is a custom node built on Substrate 3.0.

      • pallet_provider: performs resource provider registration and provider resource information storage, and provides a computational marketplace
      • pallet_resource-order: performs resource lease order functions and lease agreement execution
      • pallet_gateway: The gateway mainly has the following functions: gateway registration, gateway heartbeat detection, gateway status reset, gateway drop penalty, and receive rewards. The main role is to add the gateway as an important player in the shared computing platform

    • Hamster Gateway: p2p gateway with public IP, used to link information between resource provider and resource user, built with libp2p component, is the cornerstone of the leased resource availability, can register itself to Hamster Node. That includes the Register, Receive rewards and Configuration modules.

      • Register: Register Gateway information to Hamster Node.
      • Receive rewards: Revenue for those who provide gateway resources.
      • Configuration: Basic configuration of p2p gateway information.

    • Hamster Provider: can provide compute resources and register them with Hamster Node. Compute resources are provided using both vm virtual machine technology and docker technology. Currently vm virtual machine technology is used to better protect user privacy. That includes the Initialize configuration, Resource details, Account information and Configuration information modules.

      • Initialize configuration: Initialize configuration, including p2p seed node configuration, p2p port configuration.
      • Resource details: Available spare resource specifications (cpu, memory, etc.), and price.
      • Account information: Provide the import of the substrate account, provide the pledge of the deposit before the service, etc.
      • Configuration information: resources that have not reached a transaction are offline at any time, resource specifications, price configuration, etc.

    • Hamster Client: After purchasing compute resources in the front-end marketplace, users can view them through the client and link to them. That includes the Market, My order and My resource modules.

      • Market: A trading market where computing power providers submit idle computing power to the market and configure prices. The client can choose the configuration and price resources to be purchased to form a transaction contract.
      • My Orders: List and details of all resource orders I have purchased.
      • My resources: The list of resources corresponding to the current valid order, the client app can establish a connection with the remote resources through the list of resources.

    • Hamster Front End: Hamster Dapp, which allows users to purchase compute resources that have already been provided, and pay a certain Token to purchase a certain amount of time to use the compute resources. We can pay by the hour for more flexible use.

    Project Flowโ€‹

    Anti-malicious attacksโ€‹

    • How do you ensure the system isnโ€™t exploited and users actually fulfill the agreement?

      When the agreement is reached, the provider is required to complete the creation of the virtual machine, notify the blockchain of the completion of the order agreement, and request a heartbeat per epoch, which includes the number of cpu cores and memory size, for the blockchain to verify that it is working and providing valid resources. The potential threat is a nefarious provider forging heartbeats to trick the network into providing a valid service that actually provides less than the promised resources or even none at all. Since we have thought long and hard about this, and we do not currently have a cryptographic or better design to accomplish such a solution, we have adopted the idea of an arbitration model to prevent malicious attacks.

      1. when the user finds a problem with the resource and the information configured at the time of purchase does not match, submits a validation request and requests arbitration. in order to ensure that there is no malicious validation, the submission of the request will have a certain cost pledge.
      2. the arbitration group is subject to the validation request, currently designed to arbitrate the group for the current chain of validators. because he is the block validator, will promote the role of the current ecology. It is a trusted team
      3. the arbitration group to link the computing resources, after entering the link for linux least privilege account, to query the virtual machine specifications
      4. arbitration break to verify and report the vote
      5. according to the voting results for incentives and penalties, to achieve the purpose of malicious evil.

      We will follow up with cryptography or a better algorithmic model to replace the arbitration model. This will be a major topic of our subsequent research.

    • What are other potential attack vectors and how are you going to address them?

      • Virtual machine p2p connection security:

        The connection port of the virtual machine is exposed to the p2p network and is vulnerable to security attacks from the p2p network. When provier creates a virtual machine, it will use the public key of the purchasing user and inject it into the virtual machine. The password will be changed to a random password to ensure that no one can access it, and disable remote login by password. This protects the login security of the virtual machine.

      • Host network security:

        Mainly facing Escape Exploit . The 'Escape Exploit' problem is a persistent network security attack and needs to be solved by updating the corresponding software in time. We will iterate on the provider virtualization technology in the future.

    Future Plansโ€‹

    Our current goal is to provide distributed shared computing power. After this milestone is completed, we will be able to build our own ecosystem based on resources. That is, when everyone is willing to add their free resources to the hamster network, it can be assumed that there are near-infinite computing resources in the network, and more quality services can be built and constructed in the hamster network. For example, service providers no longer need to rely on the support of a single cloud vendor, but only need to use the computing resources in the hamster network, and the system automatically schedules the resource arithmetic needed for the services to build their own services in the form of edge computing. In addition to this, we can also provide some toolkits so that these computing resources can participate in other services with one click, such as becoming a chain node of Thegraph, so that they can participate in other networks, and later on, we can also use incentives to encourage people to develop toolkits for different blockchain ecosystems. When more and more people and more service providers participate in the hamster network, maybe it can become a truly decentralized metaverse service cornerstone.

    Overviewโ€‹

    helixstreet is a project to extend the use of Blockchain technology to genomics. helixstreet chose substrate as technology to implement a pallet to store a Merkle tree hash of genomic raw sequencing data. Relationsships ( ancestry ) can be documented in the blockchain based on relationships between genomic data. Currently we are planning to implement helixstreet as parathread.

    Ancestry data and personal genomic relationships are today stored centralized. helixstreet's approach allows the representation of ancestry data in a decentralized manner.

    Project Detailsโ€‹

    The project is in this stage just a pallet.

    Ecosystem Fitโ€‹

    The project extends the use of Polkadot ( or Kusama ) to a whole new use case. helixstreet would be an application specific parathread. It solves the problem of ownership of genomic data and the the human desire to conduct genealogical research without a central authority.

The script should calculate for every Read of every Chromosome a hash and create a Merkle tree to reduce storage. Furthermore the script should store a vector ( or the main root ) of the root hashes automatically in the Blockchain assigned to the private key. A flag is needed to distinguish between entries made by a machine ( e.g. Sequel II ) or by the identified owner of the DNA raw data ( the private key of the human being represented by the sequencing data ). The program will be realized in rust.

    Future Plansโ€‹

    The pallet is gradually expanded to document the relationship to other public keys. There is also the possibility of working together with HiFi sequencing manufacturers ( e.g. PACB ) who could store genomic footprints directly from the machines in the blockchain. Longterm we plan to develop a healthcare ecosystem in the blockchain based on genomic data.

    Selling any private data is completely out of scope of this project. The focus is to keep private DNA data private. The purpose of the project is to enable all the possibilities of owning his own DNA ( firstly ancestry research ) without revealing the whole data ( zero knowledge processing). When the raw data goes through the process of variant calling ( DeepVariant / open source variant caller / https://github.com/google/deepvariant ) groups of variants will additionally be stored in the blockchain. Scope of the grant is a genomics pallet with the described basic functionality, which should be adaptable and extensible.

    It's my personal project. It was started as Ethereum client library but recently I guess it could evolve into multi-platform client library including Polkadot / Substrate chains. Haskell is a powerful hight order functional programming language that provide industrial grade code safety because of very strict control of function side effects. For Polkadot ecosystem Haskell developers is couple of high skilled professionals that could make effective services and applications. This project reduce entry threshold and could be a good quick start for haskellers.

    Hybrid Block Explorer

    Project Overview ๐Ÿ“„โ€‹

    This application is in response to two RFPs:

    Overviewโ€‹

    Hybrid takes a unique, partially decentralized approach that improves two major problems with current open source Substrate block explorers: centralization and huge hosting requirements.

    A fully centralized block explorer typically populates an SQL database with the entirety of an archive node and stores additional data to index everything. Operating such a database reliably requires huge system resources and expense.

    When querying block information, or the chain state at any block height, the Hybrid dapp will use the Substrate Connect light client from within the browser. Alternatively, these queries can be made directly to an archive node via WSS.

    For event search functionality, the Hybrid indexer efficiently indexes events in all blocks so they can be found with a simple WSS query. For example, to find all events connected with a specific AccountId.

    This architecture has three main advantages:

    • state queries are fully decentralized - you don't have to trust an RPC provider not to lie to you
    • 100% availability - the light client doesn't depend on any centralized service that may not always be available
    • the Hybrid indexer has significantly lower system requirements - it doesn't need to store all chain history

    Eventually, Hybrid will use this centralized / decentralized approach as the basis for an ink! contract explorer.

    Because Substrate is a federated platform, it will be possible browse multiple chains from the Hybrid dapp.

    Project Detailsโ€‹

    Hybrid will be a Substrate block explorer dapp. By default it will connect to major Substrate blockchains. Additionally it can be configured to connect to any Substrate chain.

    There are two types of queries that the explorer can perform:

    • Decentralized - ideally using the Substrate Connect light client, or alternatively connecting to an archival node via WSS. For example, querying blocks or state storage.
    • Centralized - the Hybrid indexer for the chain will be queried via WSS. This is for event searching and watching, such as finding all events across all chains that relate to a specific AccountId.

    Hybrid Architecture

    Indexerโ€‹

    The Hybrid indexer will be written in Rust. It can be configured to connect to any Substrate chain.

    It will read events in all blocks using subxt and index these events in a Key-value database using the sled library. This is considerably more efficient than storing the index in an SQL database.

    subxt currently has an issue where it is not possible to query blocks prior to V14 metadata (block #7,229,126 on Polkadot). Resolving this issue is not within the scope of the grant. Once this grant is completed a further grant application will be made that includes resolving this issue.

    When decoding events, subxt needs to have the correct metadata. The metadata changes whenever a chain performs a runtime upgrade. Hybrid Indexer handles this in a very elegant way. When indexing begins it downloads the metadata for the starting block. When it encounters a decoding error it downloads the metadata for the current block and retries decoding. This means that the indexer does not have to be built with the metadata and block number of every runtime upgrade.

    To index an event, it needs to be converted into a Rust type that matches the metadata. Sometimes the metadata for an event will change during a runtime upgrade. To handle this the indexer will have Rust types for current and historic versions of all events. When an event fails to be converted into a Rust type the previous type will be tried.

    All events in all pallets that have identifying parameters will be indexed. For example the Transfer event in the Balances pallet is identifiable by the AccountId of both from and to.

    Other examples of identifying event parameters are assetId in the Assets pallet, code_hash in the contracts pallet, CollectionId and ItemId in the NFTs pallet, and MultiLocation in the XCM pallet.

    Additionally, all events are indexed by event variant.

    To download a block, a query first has to be made to determine the hash for a given block number. In order to ensure throughput is as high as possible, multiple queries to the full node will be active at the same time to avoid round-trip delay. Block processing will be in a separate thread.

    In the same manner that each Substrate chain is a separate Rust build that uses Substrate crates, each chain will need a separate Hybrid Indexer build that is configured to index the correct pallets.

    When a chain is going to potentially perform a runtime upgrade, the Hybrid Indexer for the chain will need a new release with any updated events. If an instance of the indexer is not updated before the runtime upgrade occurs, it can be restarted with the new version at the correct block number.

    WSS queries will be handled via the highly scalable tokio_tungstenite Rust library.

    In addition to the identifier being searched for, queries will be able to include start block, offset, and limit to control which events are returned.

    Consumers will be able to subscribe for new events that match a query.

    The database keys will be constructed in such a way so that events can be found using iterators starting at a specific block number. For example, for for the AccountId keyspace:

    AccountId/BlockNumber/EventIndex

    Database entries will be key-only. No value will be stored. The blocknumber and event index are all that need to be returned for each event found. This reduces the size of the index database and increases decentralization. The frontend can query the chain in a decentralized manner to retrieve the event.

    Dappโ€‹

    The Hybrid dapp will be a Vue dapp, using the Vuetify framework for the user interface. pnpm and Vite will be used for the build.

    It will use @polkadot/api to retrieve data from the chain, either via the Substrate Connect light client, or via an RPC connection to a full archival node. The Hybrid indexer will be queried via WSS.

    This grant will only include a basic dapp including:

    • block browsing, showing transactions and events
    • event searching, e.g. searching for all events connected to a specific AccountId.

    A subsequent grant application will be made to develop a richer dapp experience.

    Ecosystem Fitโ€‹

    A major issue holding back the Substrate and Polkadot ecosystem is a high quality block explorer comparable to Etherscan. We need such a block explorer to be:

    • non-proprietary
    • as decentralized as possible
    • not requiring massive system resources
    • feature-rich

    The target audience is blockchain enthusiasts and developers. Eventually end-users should not need to know about block explorers, but this depends on dapps improving their user experience.

    The indexing component has value far beyond the Hybrid block explorer. Many Substrate applications will find a centralized event indexer extremely useful.

    Comparison to other Substrate explorers / indexersโ€‹

    There are no known block explorers in other ecosystems that are indexing, and either fully decentralized or have a hybrid design like this one.

    Project Overview ๐Ÿ“„โ€‹

    This application is for a follow-up grant to the original Hybrid Block Explorer grant: https://github.com/w3f/Grants-Program/pull/1582

    Overviewโ€‹

    Hybrid Architecture

    The original grant for the Hybrid Block Explorer involved creating a Rust library that can be utilized to create an event indexer for any Substrate chain. A Rust project to index all Polkadot-based chains was delivered. Additionally, a rudimentary browser dapp was produced to provide a user interface to query the index and load event details from the chain.

    This follow-up grant application is specifically to improve the indexer component of the project.

    Project Detailsโ€‹

    Before the indexer can be used effectively by the Polkadot community, there are various improvements that need to be made:

    Indexer Improvementsโ€‹

    • Currently there are two indexer threads, one for indexing new finalized blocks, and one to index old blocks. This is unnecessarily complex. Combining these threads will make the codebase much simpler.

    • The indexer needs to verify that it is indexing the correct chain. If it connects to the wrong endpoint or opens the wrong database, incorrect data would be present in the index.

    • Terminal output needs to be improved with configurable levels of verbosity. Statistics need to be output in a regular time interval, not block interval.

    • Error handling needs to be improved. Currently many error conditions are silently ignored. Exiting needs to be handled gracefully.

    Reverse Batch Indexingโ€‹

    Currently when the indexer is indexing old blocks it starts at a specified block and works forward, eventually catching up with head. When the indexer is restarted it will resume where it left off.

    Typically users are more interested in recent blocks. If a user is indexing on their own device it can take many hours or days for the batch indexer to catch up with head.

    If the user wants to index from an earlier block, they have to re-index all the already indexed blocks.

    The solution is for the batch indexer to always start indexing backwards from head and store in the database which spans of blocks have been indexed with which version of the indexer.

    The indexer currently trusts that new finalized blocks are delivered sequentially. The indexer needs to verify that no blocks have been ommitted. If a block has been omitted or the WSS connection is broken and reestablished then the batch indexing will need to restart from head.

    Database Improvementsโ€‹

    • Currently, the event parameter types that are available to be indexed are hardcoded in the indexer library. The API needs to be extended so that chain indexers can specify custom parameter types, beyond those in Substrate.

    • In addition to indexing event parameters, the indexer can also index which variants of events have occurred. This is very useful. For example, the indexer can return all balance transfers that have occurred. This index is the largest because every event that occurs is a separate database entry. Making this index optional will greatly reduce the storage space for those users who do not need it.

    • Hybrid uses the Sled database library. Tunables cache_capacity and mode should be exposed in the indexer.

    WS API Improvementsโ€‹

    • Currently, to receive status updates it is necessary to continually query the indexer. It should be possible to subscribe to status updates.

    • It should be possible to query how much disk space is used for each index. This can be implemented using the following method: size_on_disk.

    • It is currently possible to subscribe to event searches. It needs to be possible to unsubscribe.

    • A Rust library needs to be written to make it easier to query Hybrid indexes from Rust programs.

    Project Overview ๐Ÿ“„โ€‹

    Imbue Network was born out of the growing problem of funding projects. There is a real problem in the polkadot ecosystem with funding, projects tend to launch on ETH as an easy way out due to lack of options. The problem is then compounded because of seed/private investors so by the time the token launches, their community can only get a chance to invest through severly limited whitelists

    Imbue Network wants an end to Eth raises and whitelists. We aim to solve this problem by building a parachain that allows its token holders to propose and then fund a proposal.

    Project Detailsโ€‹

    Imbue network aims to become a DAO and a parachain, so we will be heavily dependant on both Substrate/Polkadot/Cumulus

    We aim to build on top of the great work the OAK network has done around quadratic funding and build a custom pallet that holders of the Imbue network token ($IMBU) will be able to propose a new project and idea, detail how much they need and milestones. The proposal can also detail stages in their milestones and split the required amount. I.e Claire is a founder of a project and needs $100k and detailed 5 milestones. Claire needs $10k upfront to start off with then once milestone 1 is complete Claire requires a further $40k for milestone 2 and 50k for milestone 3.

    We also will build a UI that allow users to connect their polkadotJs wallet to allow other holders to vote on the projects they want to see implemented.

    Once voting completes, DAO council members will then approve the winning proposals and allocate a portion of the funds - % that was defined in milestones - immeditely.

    Once the founder believes they completed their first milestone they can use the pallet to initialise a vote, only the original funders can then vote to validate whether the milestone was completed successfully or not. If the vote passes the next stage of funds are unlocked.

    • For MVP we hope to achieve:
      • Grants pallet - where holders can propose projects/ideas and receive funding
      • Democracy pallet - where funders can vote on proposals and milestones
      • DAPP integrated with polkadotjs for a more seemless user experience.
    • What wont be ready but we hope to add
      • Funding will initially only be done via the $IMBU token, but we hope to add other currencies as we grow. We will also explore working with statemint to manage this funds

    An overview of the flow is detailed here, please bear in mind this is just showing the happy path

    We will be adding signitures for each pallet call over the next few weeks.

    Ecosystem Fitโ€‹

    We believe we are solving a real problem in the polkadot ecosystem, and cannot think of any other project that aims to do what we are trying to do.

    We do not consider IDO platforms as a solution to this problem. There is also the governance aspect which is also missing from the space but is also needed

    However, https://aragon.org/ is something similar that is built on top of Etherum. We believe our USP is the funds being unlocked in stages and allowing funders to vote on those milestones

    1.Substrate module: Democracy palletVotes pallet to allow voting on proposals (working alongside the grants pallet). Votes meant to be stored via IPFS. Voting will be done with 1 $IMBU = 1 vote.
    2.Substrate module: Funding palletWorks alongside the democracy pallet to unlock funding in the stages defined by the project orignally. This will be called after council votes on approval of funding/milestones. This will also be called by the proposer to withdraw the approved funds. Can potentially be merged with the grants pallet

    The proposed flow for milestone 2 is:

    • Given Alice is proposing an idea/project, alice submits this proposal via the UI. The proposal details can be stored on/offchain but the ID needs to be stored onchain.

    • The council approves it which then goes to voting via the democracy pallet.

    • $IMBU holders vote on the project they want to see implemented by partially funding a locked account.

    • The council then approves the initial amount (defined by Alice in her milestones ) via the treasurey pallet(if required) and unlocking a % of funds that the $IMBU holders locked

    • For each and every milestone Alice completes, she submits it and the whole process restarts again culminating with the treasury unlocking the % of funds required for that milestone. The only difference here is that only IMBU holders that funded the project (and council if treasury was involved) can vote on milestones. For simplicity's sake 1 $IMBU = 1 Vote

    The Funding pallet needs to be built in such a way where it can either fund the project proposals in the native IMBU token or in any other token. We can reuse the treasury pallet but change it in such a way to allow this iterative milestone unlocking behaviour.

    ...

    Future Plansโ€‹

    We want to build out Imbue network as a DAO, We also want to build out the ability to allocate funds on the different polkadot currencies so a proposer can choose which currency they want to be funded in

    Ideally, for future milestones, we would like to remove the need for the council completely and have this fully determined by the IMBU holders. Also a vote can be a fraction of an IMBU so your vote weight is equal to the % of the amount funded

    Work with Parity on how we can utilise Statemint with fund storage/allocation

    Project Overview ๐Ÿ“„โ€‹

    This application is in response to the anti-collusion infrastructure RFP.

    Overviewโ€‹

    Helping to empower the realization of trust in, and verification of, voting systems within Substrate parachains.

    The goal of this proposal is to provide a minimum viable implementation of Vitalik Buterinโ€™s โ€œMinimal Anti-Collusion Infrastructureโ€ as a substrate pallet and CLI (for performing off-chain work, i.e. encrypting votes, processing messages, and generating proofs).

    The scope of this proposal is intended to be a proof of concept, of which contributes to the development of a genuine minimal anti-collusion infrastructure within the Substrate ecosystem.

    Governance, and by extension voting systems, are critical facets of society at large and have become a crucial value proposition of many blockchain applications. It is therefore imperative to develop systems which not only promote a sense of underlying trust, but also can intrinsically verify their own integrity.

    The team is interested in cryptographic voting as a research domain. They would like to further explore this area in order to provide a meaningful contribution to the community. Refer to โ€œFuture Plansโ€ section to preview how weโ€™d like to see this project evolve.

    Project Detailsโ€‹

    There are two primary deliverables outlined in this proposal:

    1. A Substrate pallet which facilitates the voting apparatus and on-chain verification of poll results, and;

    2. A CLI tool to facilitate the generation of arguments passed to the methods exposed by the pallet.

    The goal of this system is to deincentivize collusion between participants given that any participant can secretly change or nullify their vote.

    Use case diagram

    Deliverables:
    1. Substrate pallet
      1. Description
        1. Facilitates transparency and provenance of poll interactions and outcome. Users can register as either coordinators or participants, create polls, and interact with polls. On-chain verification of zero-knowledge proofs (which have been generated off-chain) that establish the correctness of the poll tallying computations (which have been performed off-chain) must occur prior to the acceptance of, and publishing of poll outcome.
      2. Public methods
        1. registerAsCoordinator Permits the caller to create polls, and stores their (public) keys.
        2. rotatePublicKey Permits a coordinator to rotate their public,private keypair. Rejected if called during an ongoing poll.
        3. rotateVerifyKey Permits a coordinator to rotate their verification key. Rejected if called during an ongoing poll.
        4. registerAsParticipant Permits a user to participate in a poll. Rejected if called after voting period.
        5. createPoll Instantiates a new poll object with the caller as the designated coordinator. Emits an event with the poll data.
        6. interactWithPoll Inserts a message into the message tree for future processing by the coordinator. Valid messages include: a vote, and a key rotation. Rejected if sent outside of the timeline specified by the poll config. Participants may secretly call this method (i.e. from a different address) to override their vote, thereby deincentivizing bribery.
        7. mergePollState Used by the coordinator to compute roots of message state tree, which is used as a commitment value by the proof verification logic. Rejected if called prior to poll end.
        8. commitProcessedMessages Verifies the proof that the current batch of messages have been correctly processed and, if successful, updates the current verification state. Rejected if called prior to the merge of poll state.
        9. commitTallyResult Verifies the proof that the current batch of votes has been correctly tallied and, if successful, updates the current verification state. On verification of the final batch the poll result is recorded in storage and an event is emitted containing the result. Rejected if called before messages have been processed.
      3. Runtime storage
        1. Public key store: mapping between coordinators and their public keys (which are used by participants to encrypt their votes)
        2. Verifying key store: mapping between coordinators and their verifying keys used in the on-chain verification of proofs
        3. Poll store: mapping between poll id and the current state of the poll
        4. Poll message state: mapping between poll id and a merkle tree of secret participant messages (i.e. votes and/or nullifiers)
        5. Poll Result: mapping between poll id and outcome
      4. Dependencies
        1. We will rely on the Groth16 verifier provided by bellman under the MIT license.
    2. CLI tool
      1. Description
        1. Facilitates off-chain computations performed by participants and trusted operators. In particular, generating the values (e.g. encryption keys, proofs) required by the function signatures specified in the first deliverable (1.Susbtrate Pallet). This will be provided as a TypeScript library (in order to serve as a starting point for future integration into dApps) with a simple CLI wrapper.
      2. Technologies used
        1. Circom
        2. Typescript
        3. Node.js
        4. snarkjs
      3. Commands available to users
        1. generateKeypair Used by both participants and coordinator. Outputs a keypair used for encrypting and decrypting the messages which represent poll interactions.
        2. generateProof Used by the coordinator. Generates a proof of correctness for the current batch of message processing computations (including final vote tally).
        3. encodeMessage Used by participants. Accepts their vote as input, and outputs an encoded message which may only be decrypted and read by the coordinator.
    Poll lifecycle:
    1. Poll is created (by a coordinator). Prior to the start time of the poll:
      1. The coordinator may perform any permitted alterations to the poll configuration, or close the poll
      2. Individuals can begin to register as participants in the poll
    2. Poll starts:
      1. Coordinator may no longer preform any alterations to the poll (e.g. update signing key)
      2. Participants may interact with the poll (vote, revote, nullify vote, switch keys)
    3. Poll ends:
      1. Participants may no longer sign up or interact with the poll
      2. Coordinator may start to compute the outcome of the poll
    4. Poll result becomes โ€œfinalizedโ€ once:
      1. The coordinator publishes the result of the poll alongside proofs of the computations
      2. The result of the poll is committed to storage if and only if every proof passes verification
      3. At this point it is sensible for external actions to be taken in response to the outcome of the poll
    Constraints and limitations of the deliverables to be aware of:
    • A coordinator may only manage a single poll at a time (there may be multiple coordinators each with their own poll at any given time)
    • Users can only cast a vote of weight 1
    • Votes must be processed, and tallied, in batches
    • Non-transparent proof system (Groth16); requires a trusted setup

    We intend to improve upon these limitations in future work (see the section below).

    Ecosystem Fitโ€‹

    • Useful in governance schemes, e.g. crowd funding applications.
    • The target audience is parachain developers, e.g. a candidate integration could be the imbue network.
    • The overall intended trajectory is to help establish a sense of integrity within democratized systems. Participants in these systems are empowered to verify by default.
    • The team is not aware of any projects in the Substrate/Polkadot/Kusama which are currently attempting to achieve feature parity (or beyond) with MACI in the Ethereum ecosystem.

    Future Plansโ€‹

    1. Experimentation with alternative architectures
      1. In particular, we are interested in architectures which support on-chain tallying utilizing partial or fully homomorphic encryption, and verifiable computation schemes such as Rinnochio.
      2. Secure multi-party computation architecture which relies on multiple coordinators; this would enable complete secrecy of individual voter preferences. Ideally this would be combined with (1.i).
    2. Features and enhancements to deliverables
      1. Integration of transparent zk-SNARKS
      2. Reduce number of extrinsic calls required in the tallying phase, e.g. with Nova
      3. Support for different voting schemes, e.g. quadratic, ranked choice
    3. Additional systems and example integrations
      1. Off-chain worker (and potentially a backend service) to automatically perform the message processing, tallying, and proof generation computations
      2. dApp which provides a rich user interface for creating and participating in polls
      3. Example ink! smart contract demonstrating how to interface with the pallet, e.g. a fungible-token contract wherein the voting power of a single participant corresponds to the number of tokens they own
    4. Outreach
      1. Obtain a security audit of infrastructure
      2. Network with faculty and peers with the aim of collaborating on research goals
      3. Seek out possible integrations with a parachain, e.g. imbue

    Where appropriate, we would like to deliver some subset of these in follow up proposals.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 โ€” Semantic analyzer: Quick fixes, ink_e2e macro support, project creation command and code/intent actions for inserting code stubs/snippets for relevant ink! entitiesโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT or Apache 2.0
    0b.DocumentationI will provide detailed source documentation including rustdoc documentation that will be published to docs.rs and a README file (published on Github, crates.io and docs.rs) providing general information about the library, instructions for installing and using the library and links to other documentation and resources related to the library.
    0c.Testing and Testing GuideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. In the guide, I will describe how to run these tests.
    0d.DockerI will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Rust crate update: Quick fixes for all existing diagnostic errors and warningsI will update the semantic analyzer crate by updating the existing interface that accepts ink! smart contract code as input and returns diagnostic errors and warnings to additionally return quick fixes (suggested edits/code actions) for all existing diagnostics. I will leverage the existing methodology for extracting ink! semantic rules that was used to extract the existing (more than 74) diagnostics errors and warnings to determine the relevant quick fix(es) for each diagnostic based on the related semantic rules and context. The high-level methodology can be summarized as: 1) remove and/or replace ink! attribute for ink! attributes applied to the wrong Rust item (e.g. for #[ink(storage)] attribute applied to anything other than a struct, a quick fix to remove the ink! attribute and another to add a relevant ink! attribute, e.g #[ink::contract] if the original attribute was applied to a mod and no other ink! contracts are defined in the current file e.t.c) 2) remove and/or add/replace Rust invariants for ink! entities that don't satisfy ink! semantic rules based on expected Rust item invariants (e.g. add a self reference - i.e. &self or &mut self - to an #[ink(message)] whose fn item's parameters don't include a self reference, or remove a self reference from an #[ink(constructor) whose fn item's parameters include a self reference, or rename the associated type for a chain extension to ErrorCode if no other associated type named ErrorCode exists e.t.c) 3) move ink! entities to the appropriate "scope" (e.g. move ink! constructors and ink! messages implemented in the root of the ink! contract module to either the first non-trait impl block or create a new impl block to for them e.t.c). 4) update order of ink! attributes so that the "primary" attribute comes first (e.g. refactor #[ink(payable)]\n#[ink(message)] to #[ink(message)]\n#[ink(message)] or #[ink(anonymous, event)] to #[ink(event, anonymous)] e.t.c). This methodology should not be considered exhaustive at this point as more patterns may be found during actual implementation, in which case, they will be documented.
    2.Rust crate update: ink_e2e macro supportI will update the semantic analyzer crate to return diagnostics, quickfixes, completions, code/intent actions and hover content for the ink_e2e macro via the existing interfaces for all the aforementioned features. Diagnostics and quick fixes will be extracted using the existing methodology for extracting ink! semantic rules with the difference being the use of the ink_e2e_macro crate (instead of the ink_macro crate) as the entry point. Completions, code/intent actions (for adding the attribute macro and/or attribute arguments) and hover content will be added for the #[ink_e2e::test] macro as well as its associated attribute arguments (i.e. additional_contracts, environment and keep_attr).
    3.Rust crate update: Command for creating a new ink! project with a contract stubI will update the semantic analyzer crate to provide an interface that accepts a name as input and returns an ink! smart contract code stub/snippet similar to those created by cargo contract new.
    4.Rust crate update: Code/intent actions for inserting code stubs/snippets for relevant ink! entitiesI will update the semantic analyzer crate to provide an interface that accepts ink! smart contract code and a cursor position as input and returns code/intent actions for inserting code stubs/snippets for relevant ink! entities for the current context (e.g. in the context of the root of an ink! contract mod, code actions for inserting ink! storage - if an ink! storage struct isn't already defined - and/or ink! event code stubs/snippets which would wrap an edit that adds a struct annotated with the relevant ink! attribute e.g #[ink(event)] e.t.c). This applies to all ink! entities (i.e. contract, storage, constructor, message, event, trait definition, chain extension, storage item e.t.c.) that would be relevant for any given context - context being determined by the parent/ancestor ink! attribute annotations for the current cursor position.

    Milestone 2 โ€” Semantic Analyzer: Inlay hints, signature help/parameter hints and attribute "flattening"โ€‹

    0d.DockerI will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Rust crate update: Inlay hints for ink! attribute argument valuesI will update the semantic analyzer crate to provide an interface that accepts ink! smart contract code as input and returns inlay hints for ink! attribute argument values (e.g. u32 \| _ for selector values, u32 for extension values, &str (a valid Rust identifier for) for namespace values, &str (a comma separated list) for keep_attr values, Path for env and environment values e.t.c). Inlay hints will be provided for all ink! attribute arguments that require values (i.e env, keep_attr, namespace, selector, extension, handle_status, derive, additional_contracts, environment e.t.c).
    2.Rust crate update: Signature help/parameter hints for ink! attribute argumentsI will update the semantic analyzer crate to provide an interface that accepts ink! smart contract code and a cursor position as input and returns signature help/ parameter hints for relevant ink! attribute arguments. Signature help/parameter hints will be provided for all ink! attribute macros with associated ink! attribute arguments (e.g. env and keep_attr for #[ink::contract()], namespace and keep_attr for #[ink::trait_definition()], derive for #[ink::storage_item()] e.t.c) and "primary" ink! attribute arguments that can be combined with other ink! attribute arguments (e.g. anonymous for #[ink(event)], payable, selector and default for #[ink(message)], selector and default for #[ink(constructor)], handle_status for #[ink(extension)] e.t.c).
    3.Rust crate update: Code/intent actions for "flattening" ink! attributesI will update the semantic analyzer crate to provide an interface that accepts ink! smart contract code and a cursor position as input and returns code/intent actions for "flattening" relevant ink! attributes and arguments (e.g. converting #[ink(event)]\n#[ink(anonymous)] to #[ink(event, anonymous)], or #[ink(message)]\n#[ink(payable)]\n#[ink(selector = 1)] to #[ink(message, payable, selector = 1)] e.t.c). "Flattening" will be supported for all ink! attribute arguments that can be combined to form "compound" ink! attributes (e.g. event and anonymous for ink! events, message, payable, default and selector for ink! messages, impl and namespace for ink! impl, extension and handle_status for ink! extensions e.t.c) and for erroneously split ink! attribute macros and there associated arguments (e.g. converting #[ink::contract]\n#[ink(env=crate::Environment)]\n#[ink(keep_attr="foo, bar")] to #[ink::contract(env=crate::Environment, keep_attr="foo, bar")] e.t.c).

    Project Overview ๐Ÿ“„โ€‹

    Ink Explorer is an application that provides Ink contracts related information on Substrate based blockchains. It subscribes to blockchain and Ink modules events and store the information on its own PostgreSQL database. The backend exposes an API that can interact with the DB and run fast queries to get specific information in a short time.

    The idea of this project is to have fast way to start a node that can be used as an explorer getting live and old data for specific contracts or addresses.

    This project serves useful information that is not available anywhere else. Since the back end is in charge of obtaining information related to the balances, transactions and more, of the contracts that use Ink modules. Ink Explorer uses polkadot.js to communicate with the Substrate / Polkadot networks. It is safe to say that this project is a must.

    Blockcoders is a team that is always contributing to blockchain projects to help the growth of the ecosystem.

    Ecosystem Fitโ€‹

    Help us locate your project in the Polkadot/Substrate/Kusama landscape and what problems it tries to solve by answering each of these questions:

    • Where and how does your project fit into the ecosystem?
      • It gives a solution for all the ones that are interested in analyzing Ink contracts information.
    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?
      • Anyone who is interested in working with contracts that use the Ink protocol and has an interest in accessing as much information as possible about what is happening with said contracts.
    • What need(s) does your project meet?
      • Obtain the greatest amount of information about what is happening with contracts that use the Ink protocol in a fast and easy way.
    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?
      • There are block explorers, but these are limited to saving and accessing information related to blocks and transactions, but are not intended to provide contract-oriented information.

    Project Overview :โ€‹

    Proposal for Milestone 2 in the RFP titled implementation-benchmarking.

    Overviewโ€‹

    There are multiple ways to implement the logic in substrate i.e using pallets or ink smart contracts, or even writing solidity code and compiling it to WASM with the help of a solang compiler. We have to benchmark the performance metrics of the logic implemented using each of the above methods. We have already benchmarked the storage performance(basic data types) of each of the implementations as part of Milestone 1 and 2. Now, we will benchmark CPU-intensive logic, events emission and cross-contract calls across all the four implementations. We hope this will help new developers in deciding the best approach to implement the logic.

    Project Detailsโ€‹

    We will employ the approach already taken to deliver Milestones 1 and 2 to benchmark CPU intensive task on all the four implementation strategies and also cross-contract calls within an implementation, wherever possible. We will use following tools to do so:

    Proposal for the RFP titled ink!/pallet/solidity performance benchmarking.

    Overviewโ€‹

    There are multiple ways to implement the logic in substrate i.e using pallets or ink smart contracts, or even writing solidity code and compiling it to WASM with the help of a solang compiler. We have to benchmark the performance metrics of the logic implemented using each of the above methods. This will help new developers to decide the best tool to implement the logic.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Ink Contracts Wizard is an CLI based smart contract generation tool. It will scaffold Smart Contracts based on the options selected by the user. Once all the options are selected, user will have smart contract scaffolded in the machine.

    CLI commandsโ€‹

    CLI will have following commands.

    ink-wiazrd --help

    Print outs all the available commands.

    ink-wizard new flipper

    Create boilerplate code for Flipper Smart Contract.

    ink-wizard new psp-22

    Create boilerplate code for PSP-22 standard smart contracts, it is as same as ERC-20 standard.

    ink-wizard new psp-34

    Create boilerplate code for PSP-34 standard smart contracts, it is as same as ERC-1155 standard.

    ink-wizard new psp-37

    Create boilerplate code for PSP-37 standard smart contracts, it is as same as ERC-721 standard.

    In an interactive way, CLI will ask user if they want to have mint, burn, Pausable, Capped, Ownable, etc. functionality.

    Motivationโ€‹

    A lot of people use OpenZepplin's Smart Contract Wizard tool on daily basis since they are industry standard. We will be using OpenBrush smart contracts: https://github.com/Supercolony-net/openbrush-contracts. The reason to use OpenBrush Library is to abstract away a lot of details like OpenZepplin Smart Contracts does otherwise Smart Contracts code will end up being too bloaty.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem? Anyone who wants to quickly scaffold smart contract from the UI are our users.
    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)? Anyone who wants to create Smart Contracts on top of Ink are our target users.

    User Journeyโ€‹

    • User installs the CLI.
    • User selects option in which she wants there smart contracts to have functionality.
    • User will be able to generate the Smart Contract.
    • Smart contracts will be scaffolded in the user's machine.

    A concept and solution draft was created as part of this application and can be found in the Project Details chapter.

    As described above, we will reuse the existing IPFS node implementation developed by: offchain::ipfs. This solution is not handling the CID in a proper way. E.g. instead of returning the CID, it's just logging it out. It also provides the reading of the file thru an extrinsic. As the file is public on IPFS, that is not necessary.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Milestone 1 - Research and implementation of file upload featureโ€‹

    After the first research, the pallet implementation will be developed. The goal of milestone 1, is a fully working round trip (except the redirect feature). A web3 client, reading a file, calling an extrinsic and uploading the content of a file, will be developed. The CID information from IPFS will be stored in the pallet. Please see the chapter above ("Project Details > Upload utilities") for details.

    0d.CodeWe will provide the whole code in a public GitHub repository.
    1.Implementation of the IPFS upload extrinsicThe pallet implementation will be added, that takes bytes of a file as input parameters. Adjust the extrinsic method ipfs_add_bytes to trigger an event IpfsAdd(CID).
    2.Implementation to retrieve CID and store it on chainThe off-chain worker needs to be extended. Data (bytes) received will be added to the local IPFS node via the IPFS offchain worker. Once added, it stores the CID on chain.
    3.Implementation of a web3 clientFor testing and the use case of a tutorial, a web3 client with dedicated UI will be implemented. The client app can read the data from a file, call the implemented extrinsic and uploads the content in bytes to the Substrate node.
    4.Benchmark and adjustmentsTo check the maximum accepted file size, a benchmarking is performed. The result should give some concrete limits that will be added to the implemetation.

    Milestone 2 - Implementation of the redirect/fetch file featureโ€‹

    The goal of the second milestone is to implement the redirect/fetch utilities. A RPC request, based on a PRG mechanism, can be used to redirect to any file server, which is not limited to IPFS. If the file is not available thru a public IPFS gateway, the local node can be used to retrieve the file.

    0d.CodeWe will provide the whole code in a public GitHub repository.
    0e.ArticleWe will write and publish a Medium article to spread the word and give developers an introduction to the project and how to use it.
    1.Fetch File ImplementationImplement the logic that allows clients to fetch a file from IPFS with the Substrate node. E.g. #[prg(name = "nft_getFileById")] will be designed and developed that allows users to redirect a request, which returns Result<String>, to a file server. The PRG mechanism is used to provide a RPC API that can redirect to a file server. The existing IPFS "get file" extrinsic will be obsolet as we provide this new RPC API.
    2.Web3 Client ExtensionThe web3 client will be extend to show the (PRG) redirect feature and retrieve corresponding files via a public IPFS gateway.
    3.Local Node Fetch ImplementationImplement a file fetch RPC API, that returns the file from the local embedded IPFS node instead of the public IPFS gateway. This is helpful when waiting for the file to be available on the public IPFS gateway.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Guidelines/Assumptions:

    Milestone 1 โ€” The Iris Runtime (Foundations of the DSN)โ€‹

    Goal: The first milestone delivers a minimally functional, isolated version of Iris. Some of the functionality delivered as part of this milestone will be shortlived within Iris, as it will be moved into parachains in subsequent milestones. We deliver the functionality to add and retrieve data as part of this milestone. We intend to be able to provide end to end testing scenarios in which a node adds owned data, purchases access to owned data, and retrieves it. We also introduce the idea of the "ticket" to control access to data as well as functionality to verify tickets when processing requests to deliver data.

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can setup an Iris node, join the private network, and provide storage capacity.
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests. We intend to deliver fully functional tests along with each deliverable (which warrants testing). We intend to achieve a minimum of 85% coverage on new code.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish a weekly log explaining what was achieved as part of the grant, as well as any additional learnings that we deem important throughout development. https://medium.com/iris-blockchain
    0f.Update offchain::ipfs to latest substrate masterSync the iris fork of the offchain::ipfs runtime to the latest substrate master branch. (work is completed but needs review)
    1.Genesis State and the Private IPFS NetworkCreate a private IPFS network and encode initial bootstrap nodes in the iris genesis block. (estimated duration: 0.5 weeks)
    2.Substrate module: iris Runtime ModuleWe build the module used by nodes in Iris to ingest and eject data from the private IPFS network. The pallet's functionality includes: creating requests to add and retreive data, to create, purchase, and validate tickets, and to allow OCWs to process requests initiated by nodes (i.e. call IPFS and publish results on chain). The outcome is for nodes to be able to create owned data and to monetize access to that data via the ticket asset. (estimated duration: 2 weeks)
    3.Custom RPC EndpointWe implement the custom RPC endpoint to retreive data from OCWs as defined here. (estimated duration: 0.5 weeks)
    4.User InterfaceWe build a UI using react, polkadot.js, and js-ipfs to provide an easy way to test data ingestion and retrieval from the network and to form the basis for a potential use case and integration guide/example. This minimally functional UI will let users add data to the network, view and purchase tickets, as well as download data retrieved from the network. (estimated duration: 1.5 weeks)

    Milestone 2 - Iris as a Decentralized Pinning Serviceโ€‹

    Goal: The second milestone enables a decentralized and incentivized IPFS pinning service in Iris.

    1.Substrate module: iris-session Runtime ModuleWe build a module to enable validators to approve new network validators and for network validators to process requests to the embedded IPFS swarm. We introduce a simple reward scheme to incentivize validators to store data. The outcome of this deliverable is a fully decentralized storage network achieved by through a decentralized IPFS pinning service (estimated duration: 3 weeks)
    2.User InterfaceWe will iterate on the previous user interface to create two separate functionalities in the UI. Firstly, a "data-owner/consumer" facing page which let nodes view the availability of specific assets (number of online nodes pinning some CID), to request storage of data and to pay nodes for storage. The "data-owner/consumer" view swallows the of the functionality built in milestone 1 as well. Secondly, we build a "storage-provider" facing user interface, which displays to nodes running the embedded ipfs node their DHT stats and their rewards for pinning CIDS. (estimated duration: 1.5 weeks)

    Milestone 3 - Creating an smart contract that uses Irisโ€‹

    Goal: The third milestone delivers a decentralized application that uses Iris as a storage layer. We will deliver a smart contract (on Iris) that acts as a simple data marketplace where owners can buy and sell access to data. We also build a user interface to accompany the smart contract.

    Project Overview ๐Ÿ“„โ€‹

    This is a follow-up grant to Iris:

    Overviewโ€‹

    Iris is a decentralized data exchange protocol that enables a secure data ownership, access management, and delivery layer for Web 3.0 applications. It is infrastructure for the decentralized web. By building a cryptographically verifiable relationship between storage and ownership, Iris provides a data exchange which enables the transfer and monetization of access to and ownership of data across chains, smart contracts and participants in the network or connected through a relay chain. Iris provides security, reputation, and governance on top of storage, enabling data ownership, monetization, access management, capabilities to define unqiue business logic for data access and authorization, as well as smart contract support for content delivery. It applies defi concepts to data to represent off-chain assets in an on-chain context by representing data as a unique asset class with access to the underlying data controlled by ownership of assets minted from the asset class.

    Project Detailsโ€‹

    The intention of this follow-up grant is to implement several features that enable Iris to be a secure data exchange protocol with support for multiple storage backends, capabilties for the development of unique data access and authorization models, and that lays the foundation for future governance and moderation capabilities. In our system, data owners associate their data with any number of 'data spaces' that each have specific rule sets and inclusion policies. We also lay the foundations for our encryption scheme (we will use a threshold encryption mechanism, though the implementation of this is out of scope for this proposal) by introducing the concept of the proxy node that are the linchpin for threshold encryption, as well as allows data owners and data consumers to run light clients (as they no longer are required to run the full node and add data to the embedded IPFS node). Additionally we introduce "composable access rules" and an associated "rule executor", allowing data owners to define unique business logic that enables custom access and authorization models to their data. Further, we build a generic storage connector module which allows Iris the abilitiy to support multiple downstream 'cold' storage systems (such as using XCM to communicate with the Crust network) as well as 'hot' storage via IPFS, supported by proxy nodes, that facilitates the transfer of data between them in an offchain context. Lastly, we will build a javascript SDK to allow user interfaces for dapps built on Iris to easily build applications and interface with Iris.

    This proposal makes several improvements on top of the existing Iris blockchain, specifically in terms of security, extensibility, data organiziation, and data ingestion/ejection workflows.

    To summarize, in the following we propose:

    • the introduction of "data spaces"
    • the implementation of "composable access rules" to apply custom business logic to data
    • the introduction of "proxy nodes" that enable threshold encryption within the network
    • implementation of an offchain client to send/receive data to/from proxy nodes
    • introduce a configurable storage layer to support storage in multiple backends as well as usage of go-ipfs for hot storage
    • a javascript SDK to allow dapp developers to easily build front ends for smart contracts on Iris

    For further details, we direct the reader to view our whitepaper draft here: https://www.idealabs.network/docs

    Note: The whitepaper is outdated, specifically in sections where references to the storage system are made.

    Tech Stackโ€‹

    Frameworks/Libraries:

    • go-ipfs
    • Substrate
    • Crust Network

    Languages:

    • Rust
    • Go
    • Javascript/Typescript

    Terminologyโ€‹

    • Data Asset Class and Data Asset: A data asset class is an asset class which is associated with some owned data which has been ingested into the Iris storage system at some point in the past. A data asset is an asset minted from the data asset class.

    • Data Owner: A data owner is any node that has initiated the ingestion of some data and owns a data asset class. In the following, we may refer to data owners as "Alice".

    • Data Consumer: A data consumer is any node that owns a data asset minted from a data asset class. In the following, we may refer to data consumers as "Bob".

    • Proxy Node: A proxy node is any node that has the minimum required hardware requirements and has staked the minimum required amount IRIS tokens to become a proxy node.

    Data Spacesโ€‹

    A data space is a user-defined configuration and rule set that allows users to group data together into curated collections. More explicitly, the data space lays the foundation to enable user-defined moderation rules within the network and provides a means to securely associate disparate data sets with one another (i.e. under an โ€˜organizationโ€™). All data in Iris exists within the context of a space, however, there is no limit to the number of spaces a data owner may associate their data with.

    Under the hood, the 'data space' is an asset class which is mapped to a set of configuration items that determine the inclusion and moderation policies of the space. These asset classes exist much the same as the concept of 'data assets' from the original Iris proposal. In a data space with a private inclusion policy, only nodes holding tokens minted from the data space asset class are authorized to associate data with the data space. We see this as an additional market opportunity for the data economy, as ownership of a space may become important based on the sum of data stored within. Data spaces may also be subject to composable access rules at some point in the future.

    Further, data spaces form the basis for moderation, or curation, within the network. Each data space may have a set of rules associated with it which limits not only the type of data that can be associated with the space, but also with the contents of the data. We intend to accomplish this through the execution of machine learning models, bayesian filters, and more, within a trusted execution environment. However, that work is outside the scope of this proposal.

    Composable Access Rules and Data Access Authentication via a Rule Executorโ€‹

    Iris enables data owners to determine rules that consumers must follow when requesting their data from the network which, when met, should authorize the caller to access the data associated with the asset class. These rules could include: limited use access tokens, minimum token requirements, time sensitive tokens, and many other use cases.

    We accomplish this through a set of smart contracts called composable access rules (CARs) and an associated 'rule executor' contract. The rule contracts are composable in the sense that the data owner may specify any number of rules, each of which must be validated when a consumer requests data. In general, each rule stipulates a condition which, when met, results in the consumer being blocked from accessing data. For example, a "limited use token contract" would track the number of times a token is used to fetch data, and forces that token to be burned once the threshold is reached. If at end of execution of each CAR no false result has been returned, then the consumer can proceed to fetch the data. In general, the greater the number of CARs, the more costly it will be for consumers to access the data, since they must pay for each one to be executed.

    In order to associate CARs with an asset class, each CAR must be executed as part of a 'rule executor' contract which makes cross-contract calls to each rule specified. After execution of each rule, the executor submits the results on chain. In general, we assume that the result submission is a boolean value, where true implies each rule evaluated to true and data access is authorized, and false implies some rule failed and data is not accessible. When an executor contract's address is associated with the on-chain asset class, Iris uses a mechanism to 'unlock' the data for the authorized address for a limited period of time (until it is fetched for the first time). To this end, we introduce a new pallet, iris-ejection, which handles the management of this locking mechanism, submission of rule executor results, and association of rule executor contract addresses to asset classes.

    A composable access rule must implement the following functions, which is enforced via a trait:

    • an execute(asset_id, consumer_address) function that produces a boolean output. This function accepts the asset id of an asset class in Iris and a consumer address. It encapsulates the โ€˜access ruleโ€™ logic.

    Proxy Nodes and offchain clients for data ingestion/ejectionโ€‹

    Proxy nodes form the basis of secure data ingestion and ejection from the network. Ultimately, these nodes will be responsible for powering Iris's threshold encryption mechanism. This mechanism is out of the scope of the current proposal, however, we will create this node role to provide the foundation for subsequent work in which the threshold encryption scheme will be implemented, as well as make data ingestion/ejection workflows easier for data owners and consumers. In the implementation proposed here, these nodes simply act as ingress and egress points to/from the IPFS network. Though proxy nodes do not increase the security of the network at this point, they do remove the dependency on data consumers and data owner to run a full Iris node to enable data ingestion and ejection.

    Putting data spaces and proxy nodes together, we arrive at the following design:

    proxy nodes

    Offchain Clientโ€‹

    The inclusion of proxy nodes impacts data ingestion and ejection workflows. We will build a secure offchain client using Go in order to serve files for ingestion by proxy nodes and to listen for data sent by proxy nodes when requested from the network.

    In the initial design of Iris, data ingestion functioned by allowing a data owner, who is running a full iris node, to add some data to their embedded IPFS node to gossip with a validator node, who would then add the data to their own embedded IPFSS node, which is connected with other validator nodes. This poses several issues. Not only is it insecure, but also it forces data owners to always run a full node which limits the ease of use of the system. Similarly, data ejection functioned by allowing a data consumer to directly connect their embedded IPFS node to a validator node to retrieve data from the 'validator network', which introduced a similar set of issues that data owners would face. Proxy nodes allow us to circumvent both of these issues by acting as a gateway to the IPFS network. To accomplish data ingestion, nodes will run an offchain client, which acts as a file server that only authorized proxy nodes can call into.

    data ingestion

    For data ejection, data consumers run the offchain client which will listen for connections from proxy nodes, accept authorized connections, and provide data consumers the ability to fetch data without running a full node.

    data ejection

    Encryption/Decryptionโ€‹

    As part of this proposal, we will implement a semi-centralized approach to securing data. There are significant security issues with the design we are proposing that we are aware, specifically when any authority node chooses to act maliciously. As we are remaining a proof of authority network for the time being, we are choosing to forgo threshold encryption while we continue to build the infrastructure needed to support it.

    Our approach to encryption relies on a semi-static set of authority nodes. We propose a system where a data owner's offchain client encrypyts their data so it may be decrypted by some specific proxy node who has been selected to handle the ingestion of their data into the network. Once this is done, the chosen proxy node decrypts and re-encrypts the data so it can be decrypted by any current proxy node in the network. When data is requested from the network, a proxy node then fetches the data from the 'hot' storage system (discussed here), decrypts it, re-encrypts it for the caller, and delivers it to the offchain client. This encryption and decryption happens offchain, but not in a TEE, which we are aware poses increased security risks which we will remediate once we implement threshold encryption.

    Proxy Node Reward Structureโ€‹

    Each data ingestion and ejection transaction has an additional transaction fee which is then pooled together and distributed to proxy nodes at the end of a session based on their participation during the session. This will function similarly to how proof of stake consensus algorithms reward validator nodes when new blocks are accepted into the chain.

    Storage System Integrationโ€‹

    There are two storage layers in Iris, a 'hot' storage layer which is supported by the proxy nodes, and a 'cold' storage layer which exists offchain.

    hot-cold-storage

    We will build a generic pallet that allows for any given storage backend to be configured for use with Iris. The intention behind this is that it may allow the network to function agnostically of any one given storage solution. The pallet will expose two main extrinsics, a 'read' extrinsic and a 'write' extrinsic, which send commands to proxy nodes to either ingest data from a configured storage system into hot storage, or to store data available in hot storage into cold storage. This approach allows us to support multiple storage backends, as well as provides us the freedom to implement our own storage system in the future without impacting the user experience.

    Initally, we will demonstrate how this can be used to allow connections to an external storage backend by adapting the connector to an external, centralized data store (e.g. either a locally running file server or AWS S3), which may be useful in B2B/C solutions who want to maintain ownership of their own storage system.

    To realize a decentralized solution to storage, we will use the same approach to implement a pallet which acts as a connector to the Crust network via XCMP. Explicitly, we intend to use the xStorage pallet provided by the crust project, which allows for us to place storage orders on the Crust network. Crust IPFS nodes will then fetch data, as based on the given CID and Multiaddress, from an Iris proxy node. Further, we will integrate with the xTokens pallet to enable the usage of our native token (IRIS) to pay for storage fees. The interactions with Crust (and this would be the same for any given storage system) will be abstracted away from the user through the generic storage connector pallet, which exposes read/write functionality. We intend to follow the approach described here as well as open a dialogue with the Crust team in order to ensure all testing is sufficient and successful. We enable proxy nodes to ingest data from cold storage by reading from the IPFS gateway in which Crust has stored the data.

    In order to properly test and verify this, we will also setup our own relay chain with both Iris and Crust deployed as parachains.

    IRIS SDKโ€‹

    We intend to adapt the user interface developed as part of the initial Iris grant proposal for usage as an SDK for dapp developers on Iris. The SDK will facilitate development of user interfaces for contracts running on the Iris blockchain. As an example, the Iris Asset Exchange UI from the initial grant proposal is one such application. We will adapt the current Iris UI to use this new SDK as well as demonstrate how to develop a simple data marketplace.

    Specifically, we intend to adapt the SDK from the functions available in these files: https://github.com/ideal-lab5/ui/tree/master/src/services.

    Prior Workโ€‹

    This proposal is a followup to a completed web3 foundation grant which laid the foundation for these enhancements. With our initial proposal, we delivered:

    • a layer on substrate that builds a cryptographic relationship between on-chain asset ownership and actual off-chain data storage
    • a naรฏve validator-based storage system that encourages storage of 'valuable' data
    • support for contracts and a rudimentary decentralized exchange to purchase and sell data access rights

    In addition to these items, the Iris fork of substrate has been upgraded to by in sync with the latest substrate master branch and we have also upgraded the runtime to use the latest version of rust-ipfs (see here: d9e14294c89abd2c085e91d8312041245b5d3b35).

    Limitations and Expectationsโ€‹

    Iris is not intended to act as a decentralized replacement for traditional cloud storage or to be a competitor to existing data storage solutions. In fact, Iris is not really a storage layer at all. Further, this proposal does not address security (i.e. threshold encryption) in the network, nor does it appproach moderation capabilities, though it does lay the foundation for those items to be implemented in the next phase of development.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

      • Iris intends to be infrastructure for dapps that leverage decentralized storage and ownership capabilities. Further, our long term intention is to participate in a parachain auction once Iris is feature complete, after which we will be able to provide cross-chain data ownership that is cryptographically linked with their stored data.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

      • The target audience is very wide ranging as we aim to provide infrastructure for dapps and potentially other parachains to allow them to easily take advantage of decentralized storage capabilities. We also aim to provide tools for data owners and content creators to share or sell their data without a middleman, determining their own prices and business models. Additionally, data spaces allow organizations to control which data can be associated with them, which may allow Iris to be a used in B2B or middleware within existing centralized applications.

    • What need(s) does your project meet?

      • The basis of Iris is the creation of a cryptographically verifiable relationship between data ownership, accessibility, and storage. We aim to treat data as an on-chain asset as well as provide a robust governance and moderation framework, which can assist in IP protections and safeguarding the network from being used for abusive or malicious purposes (such as hosting malware, illicit or illegal materials, plagiarized materials, etc.).

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    Development Status ๐Ÿ“–โ€‹

    As stated earlier in the prior work section, we have delivered the three milestones detailed as part of the intiial Iris grant proposal. Additionally, we have also synced the Iris repository with the latest substrate master branch as well as have upgraded to use the latest rust-ipfs version (see here: d9e14294c89abd2c085e91d8312041245b5d3b35).

    Development Roadmap ๐Ÿ”ฉโ€‹

    Note: There are several items we aim to accomplish during the lifetime of this proposal that are not explicitly mentioned as part of the below milestones, including:

    • properly weighting and benchmarking extrinsics
    • developing automated gates for test coverage and code quality
    • developing a simple testnet and CICD pipeline to automatically update the node runtimes
    • updating our whitepaper with most recent results and findings
    • continuing research on threshold encryption and how we can most efficiently implement it, which will also allow Iris to transition from PoA consensus to PoS consensus.

    Overviewโ€‹

    • Total Estimated Duration: 9 months
    • Full-Time Equivalent (FTE): 2.5 FTE
    • Total Costs: 47,000

    Milestone 1 โ€” Implement Data Spaces and Composable Access Rulesโ€‹

    • Estimated duration: 1 month
    • FTE: 1.5
    • Costs: 10,000 USD

    This milestone delivers two distinct deliverables.

    1. We abandon the integration with rust-ipfs which was used as part of the original iris proposal. There are several reasons to do this, but the main reason is that rust-ipfs is still under development and is not yet feature complete, which severely limits its capabilities and security. Additionally, integration with rust-ipfs by embedding it within the substrate runtime significantly increases development and maintenance overhead while the benefits do not outweight usage of an external ipfs instance with go-ipfs and http bindings/communication via offchain workers. As such, this milestone will introduce breaking changes to the data ejection and ingestion workflows which are addressed in milestone 2. The results of this change implies that data ingestion and ejection are temporarily non-functional, though the underlying mechanisms are untouched. That is, this milestone introduces mechanisms to organize asset classes using dataspaces and authorization mechanisms for accessing offchain data associated with asset classes, without actually delivering the offchain data.

    2. We introduce data spaces, the ability to manage data spaces associated with data, and lay the groundwork for future moderation capabilities.

    3. We deliver composable access rules, the rule executor, and the iris-ejection pallet to the Iris network, allowing data owners to specify unique business models that consumers must adhere to across any number of data spaces. Specifically, we will implement a composable access rule and associated rule executor contract which allows a token to be 'redeemed' only a limited number of times (e.g. ownership of a token implies you can fetch associated data only N times from the network).

    7.User InterfaceWe update the iris-ui repository so as to keep calls to extrinsics in sync with changes to parameters.

    Milestone 2 - Proxy/Gateway Nodesโ€‹

    • Estimated Duration: 5.5 months
    • FTE: 2.5
    • Costs: 22,000 USD

    This milestone delivers the infrastructure to ingest data into the network and delegate decryption rights to authorized nodes.

    1. To securely ingest data, we implement two new RPC endpoints, 'iris_encrypt' that allows a node to encrypt data using proxy reencryption, and 'iris_decrypt' .
    2. We create two new node types, a 'proxy' node which enables the proxy reencryption mechanism and a 'gateway' node, which enables data ingestion and asset class creation.
    3. We reintegrate with IPFS by making http calls using the offchain client. We also build a module to bridge between IPFS and Iris.
    4. We modify the user interface to provide a simple way to start the ingestion process, view data about asset classes, and ultimately to decrypt and download data.

    7.Testnet SetupWe deploy a functional testnet to AWS that can be connected to from an iris node by specifying a custom chain specification.
    8.User InterfaceWe update the iris-ui repository so as to keep calls to extrinsics in sync with changes to parameters.

    Milestone 3 - Storage Systemโ€‹

    • Estimated Duration: 2 months
    • FTE: 1.5
    • Costs: 12,000 USD

    1. In this milestone we implement rewards and slashes for Gateway and Proxy nodes

    2. This milestone delivers a generic storage pallet that can be adapted/instantiated to communicate with any given storage system. Specifically, we will demonstrate by building two distinct implementations of this adapter, one which is capable of interacting with a centralized datastore and one which uses the Crust Network. These storage systems represent the 'cold' storage capabilities of Iris. We will also invesetigate several other 'cold' storage options, such as Arweave, Filecoin, and potentially CESS (which is currently under development and funded via the w3f grants program).

    Future Plansโ€‹

    There are several key features of Iris that are out of scope of this proposal that the team will implement after these milestones. These items are specifically:

    • The implementation of an anonymous repuation and feedback system
    • The implementation of moderation protocols within dataspaces
    • The implementation of machine learning algorithms, bayseian filters, and other checks to verify data integrity and compliance, both globally and within the context of data spaces.
    • The implementation of governance protocols, including governance as a result of moderator node actions (with the implication being that Iris becomes an opinionated network where data may be rejected and specific addresses blocked from participation in the network).

    Other non-development activities that we will pursue also include:

    • We will finalize the Iris whitepaper.
    • We will work with dapp developers to assist in develop of applications on Iris. We are already in communication with several projects that are interested in leveraging Iris as their storage system.
    • We will strive to become a parachain on Kusama and Polkadot
    • We will continue to expand the features available in Iris, such as partial ownership of assets, selling ownership of asset classes, and more

    Interoperable State Machine Protocol

    • Team Name: Polytope Labs
    • Payment Address: 0x486cbad2d704bc76f8d0cdda6aa93c94d53297b9 (Ethereum DAI)
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The Interoperable State Machine Protocol, or ISMP for short, is the product of our research into state proofs. We show that state-proof based interoperability is possible and more efficient as the messages no longer need to be routed through the relay chain and can be exchanged independent of it, while still maintaining the same level of trustlessness and security. This protocol allows not just for messaging but also state reads of other parachains in a trustless and secure manner.

    Unfortunately, Parachain-to-Parachain communication today relies on the relay chain for message routing. This is highly inefficient and relieving the relay chain of this burden will allow for better Parachain throughput and scalability. We believe ISMP is the end-game for parachain interoperability, with the relevant ISMP modules, each parachain can send and receive messages and assets to and from other parachains which also have the ISMP modules. Seconded by Rob Habermeier on twitter.

    Project Detailsโ€‹

    ISMP is a simple protocol for state machines to send requests that can be handled by a counterparty chain. Akin to the HTTP paradigm in web2, parachains can issue GET-like requests for storage reads as well as POST-like requests for sending data.

    Requests are stored in a merkle mountain range tree on the sending chain as this data structure provides some benefits, binary merkle trees have more compact proof sizes than patricia merkle tries, and in particular, merkle mountain range trees have much smaller proof sizes for recently inserted items in the tree. We believe this choice will enable higher bandwidth parachain <> parachain messaging with smaller proof sizes.

    ISMP will also support request timeouts, allowing for more safer parachain <> parachain messaging.

    Architecture

    Use casesโ€‹

    For instance a user wanting to transfer their funds from parachain A to parachain B will initiate a post request on parachain A. This post request is stored in an mmr maintained in the state trie on parachain A. Parachain A's headers also contain the root for this mmr structure.

    The user('s wallet) after observing that parachain A's headers have been finalized and made it's way into the relay chain state trie, can present a merkle proof of parachain A's header in the relay chain state trie which parachain B can verify using it's access to the latest relay chain state root. Next they present the mmr proof for the request which they had previously initiated on parachain A. After verifying this mmr proof, parachain B can "execute" the request. In this case minting the equivalent asset that was burnt on parachain A.

    There are of course other use cases that can be built on POST requests, but this is the simplest case.

    For GET requests, a different mechanism is at play. Perhaps a user wants to settle a bet they had made in a prediction market in parachain A. The data that is needed to settle this bet is on parachain B where we regard parachain B as the oracle parachain. The user initiates a GET request, with it's content the keys of the storage items they need to settle their bet. After initiating the request, the request is stored in the parachain A's mmr trie, but it is never relayed anywhere. Instead, the user('s wallet) then reads the state trie of parachain B and provides the state proof for the appropriate data that was requested.

    pallet-ismpโ€‹

    This serves as the foundational element for state-proof based messaging between parachains, enabling state reads of the relay chain directly from any given parachain, granting the ability to verify incoming messages and data from other parachains under the shared security umbrella of the relay chain.

    Custom crates

    • ismp-rs - A set of primitives necessary for pallet-ismp
      • ISMPHost: Represents a state machine's core functionality
      • ISMPRouter: Embodies the request and response routing logic for parachain interactions
      • ConsensusClient: Logic for consensus proof verification

    This module can also serve as an alternative transport layer for XCM programs.

    Ecosystem Fitโ€‹

    Currently messages are sent over the Relay Chain through opening HRMP channels but through ISMP we can increase the bandwidth of messaging between parachains without burdening the relay chain with these messages. This allows the relay chain to focus on its main task: enforcing the validity of parachain state transitions.

    Project Overview ๐Ÿ“„โ€‹

    This grant is for the RFP Social Recovery Wallet

    Overviewโ€‹

    Backgroundโ€‹

    As the RFP mentioned: "managing private keys is a difficult task." A secure, simple and user-friendly private key management solution has not yet appeared in the Web3 world. Most typical Web3 users do not have the ability to properly safeguard and manage private keys to their crypto assets and Web3 identities. Based on a latest research by ChainAnalysis, the number of lost bitcoins due to account loss has reached 3.79 million($150 billion).

    We are thus inspired and encouraged by this initiatives and create Keysafe, a decentralized key custody network together with its underlying protocols, to offer a solution that aims to keep private keys safe and 'alive' in a user-friendly way for all Web3 users.

    Descriptionโ€‹

    Keysafe is a decentralized protocol for private key backup, retrieval, and access management. Keysafe allows users to register their keys with multiple authentications (SMS, email, etc.) and access their keys from anywhere in the world securely without carrying specific devices that store them.

    Our solutionโ€‹

    architecture

    Keysafe Protocol uses Secure Multi-party Computation (MPC), Threshold BLS Signatures, and Trusted Execution Environment (TEE) technology to manage private keys and allows owners to access with a customized combination of Web2 third-party authentication services including SMS, email, Google Auth, and even another Web3 address.

    When a private key is registered in Keysafe Network, the key will be divided into multiple fragments by a threshold secret sharing scheme on user's local device and then sent to randomly appointed TEE nodes in encrypted forms. Each fragment is bound to an authentication condition set by the user, i.e. SMS, email, Google authentication, etc. The private key fragments and the corresponding authentication info will be safely stored in Keysafe's decentralized network of TEE nodes - even the TEE enclave are not allowed to read the data.

    When a user wants to access his or her registered private keys from Keysafe Network, the TEE nodes who are in charge of each fragment will initiate an authentication task, i.e. sending a verification SMS or email, according to the authentication info bound to the fragment. After passing the authentication process, the user is allowed to access his or her private keys, which can be a key retrieval, a remote Sig generation, a remote Tx generation, or a modification on the registered data.

    Project Detailsโ€‹

    Documentationsโ€‹

    • Project overview PPT here
    • Technical whitepaper here
    • API specifications here

    POCโ€‹

    We have completed a proof-of-concept to verify the feasibility of our solutions here.

    Technology Stackโ€‹

    • The TEE (Trusted Execution Environment) technology: TEE guarantees secrets to be protected with respect to confidentiality and integrity from a hardware level.
    • Secret Sharing algorithm: Based on the M-of-N Threshold Secret Sharing algorithm, privates key can be divided into N shares, and can be later restored as long as M shares are obtained.
    • BLS-MPC: Based on MPC and BLS algorithms, users can manage nodes to complete threshold signatures with their stored private key fragments.
    • The Node: Keysafe Network is made up of many distributed Nodes with TEE inside. Private key fragments are stored safely in the node's TEE enclave.
    • Web2 + Web3 authentications: The user can authenticate through Web2 or/and Web3 methods (including SMS, emails, social media accounts and Web3 accounts) to access his or her registered private keys.

    Scopeโ€‹

    There are a lot of tasks involved to get all of these into a product-ready state which is what we are always aiming for, but it'd be too extensive to fit all of the tasks into this one single open grant. Therefore, we have carved out a scope specifically for this grant, followed by the details of the future tasks.

    Grant scope

    • Develop TEE module(written in C++) that supports basic private key transfer and management functions.
    • Develop off-chain node program(written in Rust) that coordinating with TEE module.
    • Develop on-chain protocol (written in ink! smart contract) that organizes all TEE nodes into a functioning network.
    • Develop a key management tool with Web-UI (written in JS) that supports Ethereum and Polkadot accounts.
    • Implement a hybrid authentication mode that includes mailbox, password, Google 2FA, and Polkadot account.
    • Contribute SDKs for polkadot-js or polkadot-apps, so that polkadot users can use Keysafe Network to backup, recover and manage their substrate-based keys.

    Future development

    • Implement more functions in TEE, such as MPC signature and access delegation.
    • Accept nodes endorsed by more organizations.
    • Support more authentication methods such as google sign-in
    • Develop more Adapter SDKs, compatible with all users of the Substrate ecosystem.

    Ecosystem Fitโ€‹

    • Generally, Keysafe Network provides decentralized and distributed private key custody with recovery and remote access compatibility with multi-factor auth for all potential web3 users.
    • By integrating Polkadot-JS and other libraries if needed, Keysafe Network provides key management for all kinds of accounts/address in the Substrate/Polkadot ecosystem.
    • Dapps and their users will greatly benefit from the decentralized key custody service from Keysafe Network:
      • No more worrying about losing private keys and corresponding crypto assets for their accounts;
      • They can now easily migrate their private keys to new devices without copying private keys or seedphrases in plaintext and risking themselves of accidentally exposing them to attackers.
      • They can remotely access their accounts and generate signatures/transactions with multi-factor social auths, from devices that don't have private keys stored locally.
    • Futhermore, as long as Keysafe Network integrates libraries/SDKs from other ecosystem/blockchains, our users enjoy one-stop cross-platform management for their keys, accounts as well as assets held by the accounts.
    • Keysafe Network can be easily integrated into all kinds of Dapps (i.e. wallets, De-Fi protocols, GameFi projects) so that they can offer their users with a 'Log in with Keysafe' option inside their user interface. Since Keysafe's login style is significantly more friendly to new web3 users who are expectedly much familier with social auth, both Dapps and Keysafe Network realize a win-win situation from these integrations.

    Overviewโ€‹

    Backgroundโ€‹

    The novelty and complexity of smart contracts, in addition to their role in managing potentially high-value digital assets, requires a high degree of attention to be paid to their security. Yet to date it is estimated that hundreds of millions of dollars have been lost to hackers who have exploited vulnerabilities in smart contracts.

    Currently blockchain developers mainly check their smart contracts using manually written tests and source inspection by internal and external audit teams. However security auditing is a highly specialised skill (and may even be more so for Substrate chains which are based on relatively new software technologies such as Rust and WebAssembly). Further, the growing complexity of smart contracts and their composable nature makes it difficult to scale manual methods.

    Klevoyaโ€™s mission is to build automated solutions that help blockchain developers find and eliminate bugs and zero-day vulnerabilities in their code before hackers can get to them.

    Our solution: The Substrate Contracts pallet will be used to execute smart contracts written by 3rd party developers, and these smart contracts may contain a variety of bugs. In this grant we will develop a WebAssembly smart contract byte-code fuzzer (i.e. dynamic execution of the smart contract in response to random inputs) for smart contracts that are to be deployed/executed in Substrateโ€™s Contracts pallet. We will not be fuzzing the Contracts pallet itself, only the smart contacts that are to be deployed on it.

    From experience with other blockchain ecosystems we have observed that the majority (if not all) of smart contract hacks that take place are a result of logic bugs. Therefore the main objective of this smart contract fuzzer will be to identify smart contract logic bugs. An ancilliary benefit will be to identify memory corruption errors in cases where developers use non-Rust programming languages (e.g. Ask! which is based on AssemblyScript) to write their smart contracts.

    This project builds on Klevoyaโ€™s previous work developing byte-code fuzzers for other WASM based smart contract chains.

    Benefits of fuzzers:

    1. In comparison to static analysis, fuzzers dynamically execute the code and therefore tend to give results that have fewer false positives/negatives than comparable static analysis techniques,
    2. Bugs found by a fuzzer are easily reproducible as the inputs needed to recreate a bug are a by-product of the fuzzing process,
    3. Fuzzing at the byte-code level means that we are agnostic to the smart contract programming language, whether that is ink! or some other future smart contract language, and,
    4. In comparison to formal verification techniques, it is relatively easier to set up a fuzzing campaign as it does not require training and expertise in formal methods.

    Project Detailsโ€‹

    Prior workโ€‹

    We have already developed a generic, coverage guided WASM binary smart contract fuzzer. The diagram below shows the general architecture of the smart contract fuzzer (the section in the red dotted line denotes the scope of work for this grant application):

    fuzzer_arch2

    The faster one can fuzz, then the more program paths that can be explored; therefore a key design feature of the fuzzer is its ability to execute many fuzz cases per seconds (we have benchmarked it executing several million fuzz cases/sec on a 16-core CPU with WASM binaries of a moderate size).

    There are two main ways we achieve this high fuzz case throughput:

    1. Efficient compilation of WASM bytecode to optimised machine code: WASM bytecode naturally doesnโ€™t run on the processor. Modern compilers can generate high quality optimised code, but can take a long time to compile. However the compilation result can be cached, and reused between execution instances which leads to an ideal position of โ€œcompile once - run manyโ€. To get optimised machine code we leverage existing tooling, namely Cranelift JIT to lift WASM bytecode to Cranelift IR, then transpile to C++ whilst adding instrumentation that allows gathering of coverage statistics. (This multi-stage process is necessary as existing WASM JIT compilers are fast to generate machine code, but the code they do generate is of poor quality - performance wise.) The transpiled C++ is then compiled to machine code with the Clang compiler.

    transpiler

    1. Parallel execution: the fuzzer runs several (typically one per CPU core) independent WASM Virtual Machine instances (the output of the compilation step detailed above) in parallel. Each VM instance has a local seed corpus, mutator and input generator (these parts are specific to a fuzz target and we will be developing a Polkadot specific one as part of this grant). The individual VMs then periodically sync their corpora to a corpus aggregator that allows the VMs to share corpus mutations.

    Scopeโ€‹

    In this grant we will only focus on fuzzing of WASM smart contracts.

    In the future we plan to expand the fuzzer to include fuzzing of custom (i.e. developed by third-party developers) Substrate Runtimes; we plan to seek a separate grant for that activity.

    In scope:

    • Implementation of a Substrate Smart contract model for integration with our generic WASM bytecode fuzzer. The model will be API compatible with the Contracts pallet with the underlying logic being mocked as much as possible (in order to reduce the maintenance of the model in response to future changes to the Contracts pallet)
    • Development of scheme to detect simple logic bugs
    • Finetune performance of fuzzing engine

    Out of scope:

    • No fuzzing of the Substrate Contracts pallet
    • No Substrate Runtime fuzzing
    • No fuzzing of non-WASM smart contracts (e.g. smart contracts that target the Substrate EVM Pallet)

    Ecosystem Fitโ€‹

    Making DApps built on Polkadot/Kusama robust to hacking is critical to ensuring the health of, and confidence in, the Polkadot/Kusama ecosystem. To date we have not seen any tools that have been specifically developed to assess the security of Substrate smart contracts.

    The results of this project will be used by smart contract developers to verify that their smart contracts are free of bugs and vulnerabilities prior to public deployment.

    Similar work in this or other ecosystems

    • A previous Web3 grant was awarded to a team to perform WASM Runtime Fuzzing. However in that grant they specifically sought to fuzz the wasmi/wasmtime to identify errors in those components, whereas in this grant we seek to fuzz smart contracts not the runtime.
    • The greatest amount of similar work has been done in the Ethereum ecosystem where several blockchain security related organisations have developed fuzzers for Ethereum smart contracts. For example the Echidna fuzzer (by TrailOfBits) and MythX (by Consensys) which is a security suite that includes a smart contract fuzzer. Those works are not applicable here as they fuzz smart contracts that run on the Ethereum Virtual Machine (EVM) whereas we specifically target fuzzing of WASM smart contracts running on Substrate's Contract pallet.

    In conclusion: we are not aware of any teams in the Polkadot/Kusama ecosystem that are currently pursuing a similar project.

    By reducing the time required to query assets and providing a more user-friendly interface, the AssetHub Indexer aims to foster the growth and development of the Web 3.0 ecosystem in Polkadot.

    Project Detailsโ€‹

    The AssetHub Indexer is a state-of-the-art infrastructure tool designed to address developers' challenges when querying NFTs from the chain. Currently, developers are limited to querying NFTs in batches from RPC nodes, which can be time-consuming and inefficient for customer-facing products. This limitation often results in long waiting times and heavy device data loads.

    To overcome these challenges, we have developed the AssetHub Indexer. This tool leverages the power of GraphQL to provide a more efficient and user-friendly interface for developers. With the AssetHub Indexer, developers can easily query NFTs and build on top of the new NFTs pallet by Parity, opening up a wide range of potential use cases, such as creating fandom shops for art.

    Recognizing that many web developers may not have extensive experience with GraphQL, we have also built a TypeScript-based SDK that can be easily imported into any existing project. This SDK simplifies interacting with Uniques and Assets on Statemine, making it more accessible for developers of all skill levels.

    The AssetHub Indexer uses TypeScript and leverages the Squid framework (ArrowSquid) for data processing. It interacts with a Postgres database and provides a GraphQL interface for querying data. The project structure includes directories for generated model/server definitions, server extensions, data type definitions, and mapping modules. It also uses environment variables defined in a .env file or supplied by a shell for configuration.

    Currently, the AssetHub Indexer allows developers to interact with Uniques and Assets on Statemine using GraphQL. The project is designed to be as simple as possible, ensuring all tasks can be done quickly and without extended searching. We aim to reduce the time necessary to query fungible and non-fungible assets on AssetHub, making it easier for developers to build innovative and user-friendly decentralized apps.

    Architecture ๐Ÿ—โ€‹

    The architecture of the AssetHub Indexer is designed with simplicity and efficiency in mind, ensuring a seamless interaction with Uniques and Assets on Statemine.

    At the core of our architecture is TypeScript, a statically typed superset of JavaScript that adds optional types to the language. TypeScript ensures robustness and reliability in our codebase, allowing us to catch errors early in the development process and write more maintainable code.

    To handle data processing, we leverage the ArrowSquid framework. ArrowSquid is a powerful tool allowing us to process and index blockchain data efficiently. It provides a set of utilities for defining and running data processing tasks, making handling complex data processing requirements easier.

    Our project interacts with a Postgres database, a powerful, open-source object-relational database system that uses and extends the SQL language. Postgres provides us with the robustness, scalability, and performance we need to handle large amounts of data.

    On the architectural level, we have a few layers, as described in the picture above. We need to obtain the data for the correct function of our indexer. AssetHub indexer combines the SubSquid archive (the pre-indexed storage) and RPC node for the new data. When the indexer obtains a new event, it is automatically processed by the defined handler. As previously mentioned, we processed data stored in the Postgres DB.

    To expose the data to clients, we provide a GraphQL interface. GraphQL is a query language for APIs and a runtime for executing those queries with our existing data. It allows clients to ask for exactly what they need and nothing more, making it easier to evolve and enabling powerful developer tools.

    The project structure is organized into several key directories. The 'src/generated' directory contains model/server definitions created by codegen. The 'src/server-extension' directory contains a module with custom type-graphql-based resolvers. The 'src/types' directory contains data type definitions for chain events and extrinsics created by typegen. The 'src/mappings' directory contains the mapping module. The 'lib' directory contains compiled js files, reflecting the structure of the 'src' directory.

    Finally, the project configures environment variables, defined in a .env file or supplied by a shell. This approach allows us to easily manage and change the configuration without altering the codebase.

    The second state-of-the-art is our Client-first SDK called Uniquery. As we can see in the picture below, the only thing that client applications need to do is import the Uniquery package via ESM/CJS (Javascript targets). Once we have the Uniquery package, we can access query builder implementation (such as client.getCollectionById(id)). Additionally, because many developers are familiar with REST API, we build a similar fetch strategy without needing a third party (every client fetches data directly from SubSquid). The REST looks like this: $fetch(/collectionById/${id}).

    Technology Stack ๐Ÿ’ปโ€‹

    Ecosystem Fitโ€‹

    The AssetHub Indexer is a crucial addition to the Polkadot and Substrate SDK ecosystem. It addresses the challenges developers often encounter when building on top of runtime pallets, particularly when interacting with Uniques, NFTs, and Assets on Statemine. The AssetHub Indexer provides a comprehensive NFT-oriented data solution, simplifying the development process and enhancing the efficiency of dApps within the ecosystem.

    Our solution stands out within the Polkadot and Substrate SDK ecosystem due to its user-friendly GraphQL interface and TypeScript-based SDK. These features streamline interaction with Uniques and Assets on Statemine, reducing the complexity of querying these assets.

    Moreover, the AssetHub Indexer is designed to be versatile, supporting a broad range of use cases. Developers can also leverage our sub-scaffold UI template to bootstrap their projects quickly. This template, a forkable Substrate dev stack focused on rapid product iterations, accelerates the development process and allows developers to focus on creating innovative and user-friendly dApps, rather than getting bogged down in the initial setup.

    Our target audience for this proposal includes Web3 projects and blockchain developers, whether they are just starting out or already established within the Polkadot and Substrate SDK ecosystem. We believe the AssetHub Indexer can provide significant value to these developers, enabling them to build more efficient and user-friendly dApps like KodaDot.

    AssetHub also plays significant for the KodaDot NFT marketplace, which is one of the main consumers for this indexer. Thanks to that, developers can find real-world examples of how to effectively make GraphQL queries and learn more about using Uniquery.

    Regarding competition within the Polkadot and Substrate SDK ecosystem, the AssetHub Indexer differentiates itself through its focus on NFT-oriented data solutions, user-friendly interface, and commitment to simplifying the development process. Including the sub-scaffold UI template further sets it apart, providing developers with a ready-to-use foundation for their projects. Moreover, the AssetHub Indexer is already being utilized by Subsocial and KodaDot, demonstrating its practical application and effectiveness. We plan to further promote the indexer within the ecosystem to onboard new developers and explore new solutions. These factors position the AssetHub Indexer as a unique and valuable tool within the Polkadot and Substrate SDK ecosystem, ultimately serving as a Common Good solution.

    Additional Information โž•โ€‹

    The AssetHub Indexer project continues our team's various projects and implementations in the Polkadot ecosystem. We have already attracted interest from developers within the Polkadot and Kusama ecosystems. Notably, we have in 2019 previously received a grant from the W3F for creating Vue.js UI utilities, components, and libraries, details of which can be found here.

    This previous grant allowed us to reimplement keyring into Vue.js & TypeScript, demonstrating our hands-on experience with the polkadot.js.org/common utilities. The result of this work can be seen in the web-based Subkey tool.

    We learned about the Grants Program through a personal recommendation. We believe that our project aligns well with the program's goals, and we are excited about the potential to further contribute to the Polkadot ecosystem.

    Future Plansโ€‹

    After delivery, we will start to explore cross-chain lending senario and will first try to enable cross-chain asset to be lended and borrowed. Konomi aims to bridge the gap between crypto and fiat world by offering an easy to use, high performance product for users to trade and manage their crypto assets. In the mid term, we plan to implement cross-chain lending aggregation protocols since the current products could not execute orders across parachains simultaneously. We plan to deploy lending modules to partnered parachains in order to support cross-chain lending. In the long term, acquiring fiat-based customers and improve Polkadot cross-chain protocol to more compatible with cross-chain lending are the two strategic focus. In terms of fiat to crypto gateways, there have been many licensed service providers but it is yet to achieve mainstream adoption. With regulated players eying in this space, there will be more users and more demand for DeFi products. Furthermore, we believe that cross-chain infrastructure is going to be an important building block for crypto industry going forward since current solutions for BTC and other assets supported on Ethereum are either centralised or slow in speed.

    Overviewโ€‹

    Milestone 1 โ€” Verify Production of Concepts (POC) and Implement Substrate Modulesโ€‹

    In this milestone, we will verify features with limited users and launch the testnet for the production of concepts. The implementation of off-chain workers of Substrate Framework will be built and validated.

    0b.DocumentationDocuments containing the description of whole architecture design for Kylin Network.
    0c.Testing GuideWe will provide a full test suite and guide for the POC.
    1.Kylin Network Oracle Node Module RepoOracle Node for data feeding built on top of Substrate 2.0 as a customized module written in Rust will store and process the data query request from data consumers, also it will handle the data feeding from miners. The very consensus protocol and the simplest schema of oracle market are implemented inside.
    2.Kylin Network Data Feeding/Miner RepoIt handles the query requests from oracle nodes, and feeds the data after processing as requested. It will be implemented with Substrate 2.0, and the major data feeding part will be built with off-chain workers. We will perform configuration and optimization work to make this easier for typical use cases of the Kylin Network.
    3.Kylin Network Datasource Sample RepoThe sample datasource provider provides the data (e.g. the data provider fetches the spot and contract data from derivative exchanges) to be used by miners. It will contain two parts, the Java data retriever to access APIs from exchanges and the NodeJS datasource to handle data feeding.
    4.Docker ImageThe Kylin Network docker image contains the POC version which can be running anywhere to verify the idea of Kylin Network.
    5.Kylin Contracts RepoThe smart contracts with Ink! to access oracle data and provide API for external calls.
    6.Kylin Market Front-end RepoThe Oracle Data Market front-end based on polkadot js to listing all available Oracle Data Services provided by providers through the Kylin Oracle Market.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    Introductory noteโ€‹

    We chose to start the development from our own resources in order to properly set our strategy and to show concretely what we are doing and what our future contribution could be.

    Milestone 1 โ€” Implement account protection and recoveryโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationDocumentation on how to run the wallet is available in the README of published repositories (see below) and formalized in this docker compose file: it describes a simple single-node local setup for testing purpose.
    0c.Testing GuideEach component comes with a set of unit and integration tests. However, this milestone is more about delivering a user experience. It is therefore advised to instantiate logion locally and use the Web application to execute the protection and recovery processes. This can be easily done using Docker Compose and logion test, a project enabling the easy deployment of logion for testing. The processes to execute are described in the README here and here. Logion test version 0.1 must be used. The Docker images to use have tag grant1-milestone1 (see here).
    0d.DockerWe provide Dockerfiles that can be used to test all the functionality delivered with this milestone.
    1.Logion nodeWe deliver logion's Substrate node version 0.1.0 including the recovery pallet in its runtime. The node is based on Substrate Node Template v3.0. The code (Rust) is hosted here. This file describes logion's runtime configuration.
    2.Off-chain serviceWe deliver the version 0.1.0 of companion off-chain service handling protection requests (the first step for a wallet user before being able to actually get the protection of legal officers) through a REST API implemented in Node.JS/TypeScript. The code of the off-chain service is available here. The controller implementing the REST resources for protection request handling is defined in this file. Unit tests are located in this file. Note that most resources require the caller to be authenticated. The authentication "protocol" is described here and implemented using resources defined in this file. Tests are here.
    3.Web applicationWe deliver logion's Web application (React/TypeScript) version 0.1.0 which enables the execution of the process described at point 0c. The code is available here.

    Milestone 2 โ€” Implement node directoryโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationDocumentation will be included in the README of the published repository.
    0c.Testing GuideThe node directory service will come with a set of unit and integration tests. It will also be included in our logion test project (see Milestone 1). As a result, it will be possible to test the integration of the new component in a locally running logion infrastructure. From a user experience perspective, there should be no difference. However, when inspecting the requests issued by the app, it will be clear that the list of available legal officers is loaded from the node directory. The Docker images to use for testing will have tag grant1-milestone2.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish a Medium article to communicate to the Polkadot/blockchain community that logion is developing its decentralized wallet secured by legal officers, having an insititutional social recovery functionality already implemented.
    1.Node directoryThe source code of the node directory, a Node.JS service written in TypeScript, will be published in a yet-to-create repository of Logion's GitHub organization. The goal is to have a service matching the specifications given in the Components section.
    2.Web applicationLogion's Web application (React/TypeScript) will use the list coming from the node directory instead of a hardcoded list currently.

    Milestone 3 โ€” Implement distributed backupโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationDocumentation will be included in the README of off-chain service's repository.
    0c.Testing Guidelogion test project (see previous milestones) will include the deployment of IPFS services. It will also include a couple of scripts enabling the simulation of a node's failure and recovery. The Docker images to use for testing will have tag grant1-milestone3.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Distributed backupEncrypted backups of the database will be stored in the IPFS cluster as described above in the paragraph about fault tolerance in the Architecture section. Configuration (for PostgreSQL) and/or scripts (Bash) needed to actually enable this will be published in the off-chain service's repository. logion test will expose IPFS configuration (additional services in the Docker Compose file).

    Milestone 4 โ€” Multisig serviceโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationDocumentation will be included in the README of the wallet repository and a use-case will be added to the README of logion test.
    0c.Testing Guidelogion test should be used to instantiate locally a logion infrastructure. The procedure to follow in order to test multisig is described in logion test's README. The Docker images to use for testing will have tag grant1-milestone4.
    0d.DockerWe will provide a Dockerfiles that can be used to test all the functionality delivered with this milestone.
    1.Web applicationThe multisig feature as part of our Web application (React/TypeScript). It will essentially consist in the possibility for a wallet user to request the creation of a multisig address with a legal officer. The signatures of the regular user and the legal officer will then be required to transfer tokens out of this account. Such transfers will always be created by the regular user and counter-signed by the legal officer.
    2.Off-chain serviceThe multisig feature in the form of REST resources and a model in logion's off-chain service (TypeScript).

    Future Plansโ€‹

    Beyond the improvements that could be brought to the service, the most important challenge could be to find a solution to provide our wallet to the whole DotSama ecosystem. For this, we need an access to the relay chain, at least, in the Kusama environment first.

    The wallet logion could then be used to secure all the digital assets of DotSama.

    It should also be available for nominators with the stacking function enabled.

    ChainSafe is a global leader in blockchain research and development and specializes in the designing and building of web3-related infrastructure. We believe that empowering developers with blockchain-agnostic tools is essential for the future of decentralized systems.

    The firm encompasses top engineering talent from around the globe and also enjoys a strong reputation within the blockchain community.

    In addition to protocol-level client implementations (such as โ€œGossamerโ€ on Polkadot), ChainSafe also has demonstrated experience of developing a Metamask Snap for the Filecoin Foundation "Filsnap" as well as engineering the SubstrateSnap (formerly Polkadot-Metamask Snap) itself. Further, ChainSafe is currently in active discussions with a number of blockchain foundations that are exploring Metamask Snaps. We believe that this experience uniquely positions us as an ideal choice to maintain the SubstrateSnap.

    In addition to the above, ChainSafe also rounds out its deep Web 3.0 portfolio with undertakings into product development such as the privacy-first decentralized storage solution ChainSafe Files, among others such as the ChainSafe Gaming SDK and ChainBridge.

    Development Status ๐Ÿ“–โ€‹

    Approximately 2 years ago, Node Factory (recently acquired by ChainSafe) submitted a grant proposal for the maintenance of the SubstrateSnap (formerly Polkadot-Metamask Snap). As the market was not quite ready for Snaps at the time, it was decided that Snaps would be put on hold until further notice.

    https://github.com/w3f/General-Grants-Program/pull/244

    ChainSafe would like to formally re-apply for this grant as we feel that there is now a real need for Snaps in the market.

    After recent discussions between Bryant Soorkia (ChainSafe - Business Development) and David Hawig (W3F - Head of Grants), it was established that a crucial factor in determining the necessity of Snap maintenance would be confirmation of Metamask's intentions to implement the snap into the full version of the Metamask and not just Metamask Flask.

    Following this, ChainSafe and Metamask had a discussion on Wednesday the 9th of March 2022, and confirmed that Metamask will shortly be announcing a Snaps rollout timeline for several different chains. It is expected this announcement will be made in the next few weeks. One such chain will be Filecoin (Filsnap), a project that ChainSafe also engineered. Although we do not yet know the exact date, Metamask has indicated that the SubstrateSnap will be included in the roll-out of all Snaps.

    Evidence of the above has been shared with David Hawig via email.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Why the Specific Project Should Continue Being Supported:

    Given that Metamask has recently shifted its focus towards interoperability and as such, Snaps, we believe that this presents an ideal opportunity for The Web3 Foundation to leverage first-mover advantage. By maintaining the SubstrateSnap, it will allow W3F to take advantage of this by being one of the first Snaps that are ready for deployment prior to launch.

    Overview of the Features/Bugs That Need Development Contributions:

    1. Complete a rewrite of the SubstrateSnap to conform to the new Metamask Snaps API.
    2. Update the @polkadot/api library to the latest version and ensure that it works with Lavamoat.
    3. Update the Demo and Wiki page.
    4. Open a Github Pull Request on https://polkadot.js.org/apps/#/explorer to enable the usage of Metamask Flask via Snap.

    Assurance That the Current Project Owners Are Willing to Review/Accept Your Contributions: We are owners of the SubstrateSnap repository. Further, the maintainers of Polkadot applications are open to accepting a pull request that adds Snap functionality as described here: https://github.com/polkadot-js/apps/pull/2865

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The aim of this proposal is to contribute and support the community in the face of multiple challenges connected to the use of Ledger applications in the Polkadot/Kusama/Substrate ecosystem.

    Our previous maintenance contract expired several months ago. Because of our commitment to the community (without funding or a contract), we have still been keeping track of support requests and upgrading applications as new runtimes were being released. In this respect, we are already discussing proposals to the respective treasuries but this process requires a deeper legal assessment on our side that may take several more weeks to get resolved.

    Because of the incredible success of substrate based projects, a sizeable amount of new users have recently joined the community. It is important to state that Zondax did not design or operate any web, desktop, mobile or browser extension in the Substrate ecosystem.

    Unfortunately, in recent days, changes to the user interface of Polkadot.js have resulted in some users incorrectly sending funds to destination addresses (actually public keys) derived for other networks. Although these funds are not irrecoverable, at the moment, these users cannot recover funds without a deep technical understanding of the problem. Actually, we do not recommend any of these stopgap solutions, and employing them may compromise the secrecy of Ledgerโ€™s mnemonics.

    For this reason, we would like to propose a series of steps to address and mitigate future similar issues. As previously mentioned, we consider part of this grant as an intermediate step towards a fully treasury based approach. Unfortunately, given the urgency, we believe that in order to respond adequately, an open grant is more appropriate until we analyse in depth some legal uncertainties in the treasury model.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Introductionโ€‹

    Ledger App Standard Runtime Upgrades: Along the period of time covered by this grant (16 weeks), we will keep upgrading both the Polkadot and Ledger apps to align with important runtime upgrades, in particular, those that are not backwards compatible because of tx_version changes. We are already aware of some important changes happening in a few weeks.

    Ledger App (Polkadot & Kusama) Recovery Extensions: We propose creating a special configuration setting that users can enable to allow for cross-chain derivation (multiple BIP44 derivation) on both Kusama and Polkadot apps. This would allow users to retrieve funds that have been sent by mistake to keypairs in other BIP44 paths and that are currently not easy to recover.

    JS key derivation library: We strongly recommend not using mnemonics anywhere but on the HW wallets themselves. However, we understand the need for a simple tool to independently verify key derivation. For this reason, we propose creating an npm JavaScript and/or Typescript package that can derive keys in the exact same way that Ledger devices do.

    Support: In Polkadot / Kusama, we do not develop or operate web/desktop/mobile wallets, servers, user interfaces, etc.. However, given our involvement in the community (and the fact that we have developed both Ledger apps in addition to other related grants), we are currently receiving a sizeable amount of requests and support questions.

    A large quantity of questions refers to the aforementioned problem (locked funds). In other cases, they are mostly about misusage or lack of training on polkadot.js user interface, connection issues or questions about polkadot and kusama network operations. We believe that newcomers to the ecosystem would definitely profit from a much better support experience and we can contribute to this. We also think that a closer collaboration and joining forces with https://support.polkadot.network would be a major improvement.

    Last but not least, in the following weeks after the release of the "recovery extensions", we understand that adequate and specific guidance and support will be necessary.

    In this respect, we propose:

    • To reactivate and improve our processes, response times and broadening the range of questions that the team at support@zondax.ch are able to answer.

    • To improve coordination with https://support.polkadot.network.

    • To develop and expand a Polkadot/Kusama support website with documentation and articles that address a large quantity of the typical support questions that Zondax receives every day.

    Private coins can be spent and transferred by tx_transfer, which takes a set of input private coins to be consumed, and transfers their total value to a set of output coins: which could be either private or public.

    To transfer a private coin, a user need to provide a zero knowledge proof of she knows the old coins, new coins, and the secret key of old coin such that:

    1. both the new coins and old coins are well formed
    2. the address secret key matches the public key
    3. the old coin's commitment appears as a leaf of the merkle tree representing ledger state
    4. The set of old coins and the set of new coins have the same total value (minus transaction fee).

    The new coin will be posted on chain using public key encryption.

    Manta DAXโ€‹

    Manta Decentralized Anonymous eXchange scheme is based on zkSNARK and AMM. The overall design intuition is that the ledger maintains x*y = k (or using some more sophiscated curve) invariant for an exchange pair. The validation logic requires that trader provide an zero-knowledge proof of the fulfillment of this invariant after trading. Below is a simplified architecture of Manta DAX:

    (Please see section 4 of the white paper for more details.)

    Implementationโ€‹

    Manta DAP will be a substrate module. The ledger state will be a list of Merkle roots, i.e. (L_A, L_B, ..., L_N), where each merkle root represents the commitment list of a base coin. Manta DAP also support registering new coins that is compatiable with Manta DAP interface.

    We will implement Manta as two parts:

    We will only build Decentralized Anonymous Payment (DAP) in this grant since the whole project (DAP+ DAX) is too large to be implemented in only one grant.

    Ecosystem Fitโ€‹

    The current ecentralized exchanges scheme lack privacy, anti surveillance interoperability, and anonymous cryptocurrenciesโ€™ lack of price stability. As the first decentralized anonymous payment that could support existing assets, Manta DAP will be a great addition to Polkadot eco-system since Polkadot and Parachain assets such as aUSDT and wrapped BTC can be transferred and spent privately. We already talked to Polkadot eco-system members such as Acala and Equilibrium. They showed strong interests of integrating with Manta. Also, Manta DAP will be the an important building block for Manta DAX (Decentralized Anonymous eXchange) scheme that enables privacy preserving AMM style decentralized exchange using zkSNARK.

    Milestone 1 โ€” Manta DAP Protocol Prototypeโ€‹

    The major deliverable of this milestone is Manta substrate pallet that support the basic DAP scheme:

    1. Mint private coin, a user could mint a DOT/KUSAMA coin to a private coin in Manta
    2. Transfer private coin, a Manta user could transfer a private coin to another user Manta user by providing an address and a zero-knowledge proof of the private coin that she owns

    The Manta substrate pallets includes the ledger state implementation, the transaction validation logic which involves the validation of zero-knowledge proofs. Note that this milestone will only support converting DOT/KUSAMA to private coins.

    1. Support minting Parachain asset via XCM. This requires the following:
      • An token abstraction layer in Manta code that unifies Relay chain native token, parachain native/non-native token.
      • Mint/reclaim tokens from/to the sister parachain / replay chain.
    2. MantaPay wallet protocol and wallet implementation:
      • MantaPay wallet protocol (a draft version here). The purpose of this protocol is to provide the user account abstraction despite MantaPay's UTXO design.

    • Team Name: Codelight
    • Payment Address: 0xD068C7E05CF20fcEE618C8F9207e019020c62F35
    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • Codelight team's vision is to build a decentralized, user-operated, and governed Blockchain Distribution Network. To achieve the goal, we build Massbit blockchain on Substrate framework, with MBT token to create an economy, where Node Providers stake and earn Massbit token for servicing the BDN and Consumers pay in token for global access to decentralized blockchain APIs.

    • The majority of existing dApps are utilizing blockchain Infrastructure-as-a-Service (IaaS) such as Infura or GetBlock to shorten the time to bring their products into production. Those blockchain IaaS services have gained traction quickly and contributed to the growth of many layer-1 and layer-2 blockchain networks. But that added value comes with downsizing that many "dApps" rely on a centralized blockchain IaaS service and are prone to outages caused by IaaS providers. Massbit Route eliminates blockchain API single-point of failure by forming a global network of Independent node providers to allow dApps access to the nearest blockchain data source with optimal response time.

    Project Detailsโ€‹

    Architechture Overviewโ€‹

    • Massbit Route is a blockchain distribution network (BDN) operated and governed by users all over the globe. It provides decentralized applications access to different blockchain APIs by routing request network traffic to a blockchain node with optimized response time. In addition, Massbit Route is built to provide performance-optimized access to blockchains and aims at eliminating blockchain API single-point of failure by forming a global network of independent Node Providers. We build a network operated and serviced by users that provide fast and redundant access to blockchain sources. Massbit Route facilitates a network of Gateways and Nodes infrastructure in 6 different zones around the world:

      • Asia
      • North America
      • Africa
      • Europe
      • South America
      • Oceana

    • Users can join the Massbit network as Providers from any of those regions by running Massbit Nodes and Gateways connected to blockchain data sources such as Ethereum or Polkadot. As the Massbit network grows in the number of Nodes and Gateways as well as independent node providers, the network becomes highly available and redundant. When a Provider experience an issue with their nodes, blockchain API requests will be served by other Providers, which eliminates single-point-of-failure in Web2 CDN architecture.

    Componentsโ€‹

    | 1. Massbit Core

    • Massbit Core (MC) is the orchestrator of the entire Massbit network. New Nodes and Gateways that need to join Massbit network can obtain installation script and network configuration generated by MC.

    • MC works along with other components to onboard new Gateways and Nodes onto the Massbit network, and make sure traffic is routed by Gateways and Nodes effectively. When Providers need to operate Nodes or Gateways in the Massbit network, they need to obtain a set of instructions created by the MC from the Portal for their servers. By executing the instructions in the form of a bash shell script, the server will negotiate with MC and Verification Service if it is qualified to participate in the MassBit routing network. Once a Gateway is successfully verified in the Massbit network, MC provides a list of dAPI entry-points and Nodes in the same zone the Gateway needs to server request and forward traffic respectively.

    • As the Massbit Route network grow globally and blockchain traffic needs to be directed optimally, MC constantly updates Gateways with a set of traffic routing and handling instruction to adopt a change within the Massbit network. For example, when some nodes in a zone go offline, new nodes are added or Consumers adjust the request rate for dAPI entry-point, MC generates a new set of configurations for all of the Gateway in the zone.

    | 2. Gateway Manager

    • Gateway Manager the DNS component of Massbit network based on the opensource project gdnsd. It runs as an authoritative DNS system of the Massbit network, and can be seen as a directory for all Community Gateways and Nodes around the world.

    • When a dApp queries blockchain API through a Massbit dAPI entry-point, it needs to lookup the IP address for the dAPI entry-point through their configured recursive DNS servers. If the recursive DNS servers do not have the entry for the dAPI entry-point, they will perform an authoritative lookup to Gateway Manager. With geographic IP capability, Gateway Manager resolves the DNS lookup with the IP of the Gateway closest to the requesting dApp based on the source IP in the request Header.

    • A dAPI entry-point URL has the following format:

    https://[API ID].eth-mainnet.massbitroute.net/[API key]
    wss://[API ID].eth-mainnet.massbitroute.net/[API key]
    • The host portion in the dAPI URL is a dynamic DNS entry in Gateway Manager. The resolved IP in the authoritative response by Gateway Manager will vary depending on the source IP in the request Header.

    | 3. Session Manager

    • When a dAPI entry-point is created by Consumer, a dynamic DNS entry is created by Gateway Manager and resolved to the nearest Gateway IP based on the source IP in the request header. Once traffic reaches a Gateway, in order to accept the API request from Consumers, it needs to obtain a dAPI session key from Session Manager. The session key is only valid for a certain amount of time and will be renewed for the dAPI entry-point if needed.

    • In addition, Session Manager also controls the usage of the dAPI entry-point. Consumers need to deposit MBR tokens for the dAPI entry-point in advance to pay for the cost of dAPI usage. Depending on the amount of MBR deposit, Consumers will receive a corresponding quota for dAPI usage. Session Manager will inform if a dAPI entry-point is out of quota and Gateways will block incoming request until more MBR token is funded for the dAPI.

    • Session Manager also prevents malicious actors from bypassing dAPI payments and sending blockchain requests directly to Gateway public IP. Without a valid session key and a dAPI entry-point, Gateways will reject the requests destined to their public IP. This will maintain the security of the network and form a building block for Massbit Route token comic.

    | 4. Stats

    • Stats collects telemetry from all verified Gateways and Nodes in the Massbit network. The service provides different metric data to allow the Portal to visualize Nodes and Gateway performance with charts. In addition, it calculates and keeps track of the available quota for each dAPI based on the amount of MBT token deposit.

    | 5. Fisherman Pallet - Decentralized Node Verification Service

    • Massbit Route becomes a faster and more reliable BDN when the number of Community Nodes and Gateway increases. For that reason, Nodes and gateways need to meet certain bandwidth and latency requirements checks by Fishermans in order to be part of Massbit global network. Fisherman Pallet is an Off-Chain Woker that is included with the Massbit Gateway installation script. The more Massbit Gateways are deployed, the more decentralized this service become, which make the process of node/gateway onboarding un-biased.

    • When a Node requests to join the Massbit network, nearest Fishermans checks if the Node is able to forward requests to its blockchain data source and return results matching with the blockchain data source such as block data, block hash, and runtime version. If all checks passed the validation process, the node becomes a part of the Massbit network and gets ready to receive traffic from Gateways in the same zone.

    • In each zone, a minimum of 1 Node is required in order for a Gateway to be verified. Without any Node or blockchain data source, it is unnecessary to run a Gateway in that zone because it introduces some routing overhead, and traffic will eventually be routed to the nearest zone.

    • When a Gateway needs to join the Massbit network, Fisherman will validate if the Gateway has obtained a list of Node in its zone from Massbit Core and whether it can proxy traffic to the Nodes properly. If blockchain data returned by Gateway is correct and match with data from the Node and blockchain data source in that zone, the Gateway is verified and its public IP is updated in the Gateway Manager directory.

    | 6. Massbit Route blockchain

    • Building on the Substrate framework, the Massbit chain is a source of truth for token-related activities in the Massbit network. Massbit Consumers need to pay fees in MBT tokens in exchange for global dAPI service. In return, Providers earns rewards from Consumers' fee for handling blockchain API requests and maintaining the stability of the network. Through the Massbit chain, anyone can verify Providers' and Consumers' activities with the following pallets:

    • Provider/Delegator activities Pallet

      • Staking/Un-staking amount on each Node/Gateway
      • Reward calculated after each Era from Consumer fees โ€‹
      • Reward claim history โ€‹
      • Node/Gateway State reported by Fisherman โ€‹
      • Node verified duration eligible for staking rewardโ€‹
      • Provider Wallet and transactions
      • Staking/Un-staking amount on delegated Node/Gateway

    • Consumer activities Pallet

      • dAPI deposit fee
      • dAPI remaining quota based on past usage on the deposit fee
      • Consumer wallet and transactions

    | 7. Portal

    • Portal is the user interface of Massbit Route that allows user to user to perform the following activities:

      • Create/stake/unregister Nodes and Gateways
      • Obtain the installation script for Nodes and Gateways
      • Claim reward for Nodes and Gateways
      • Visualize traffic of Nodes, Gateway, and dAPI entry-point
      • Create dAPI entry-point and view the quota
      • Deposit fee for dAPI

    | 8. Community Gateway

    • Gateways are entry-points to the Massbit network, which receive blockchain API requests from dApps. It keeps a list of verified Nodes in the same zone, and forward requests to those nodes. It also stores static content of blockchain requests to reduce the response time for identical requests that come in later
    • Utilizing Open Resty framwork, Gateways are repsonsible for blockchain traffic within each zone. The robust functionalities of Open Resty framework allows advanced and efficient routing capabilities for Massbit dAPI entrypoints including:
      • Load Balancing for multiple Node-as-a-Service enpoints like Infura or Getblock
      • accepting blockchain requests from dAPI entrypoints
      • Rate limiting
      • Geo IP detection and routing for optimal response time
      • Edge caching
      • Routing to only functional Upstream servers (Massbit Node)

    | 9. Community Node

    • Community Nodes receive requests from upstream Community Gateway and forward them to the attached blockchain data source. In addition, it works with Massbit Fisherman to make sure the data source is available and synchronized with peers before it can receive new blockchain API requests from Gateways.
    • Also utilizing Open Resty framework, it acts as one of the Upstream Servers for all of the Massbit Gateways in the same zone, and forwards traffics to its own blockchain data source.
    • Node Providers can make their own decision whether to run Massbit Node and blockchain RPC node on the same host/server or different ones.

    Traffic Routing Mechanismโ€‹

    • In the Massbit network, Gateway Manager, Community Nodes and Community Gateways form a global blockchain CDN network in order to optimize blockchain API request and response time.

    • Based on the public IP of each community-run Node and Gateway, a global geographic map of verified and staked Gateways is continuously updated. When a dApp sends a blockchain API request through Massbit Route API Entrypoint created by a Consumer, based on the global network IP map, the request is forwarded to a Gateway in which its zone is the same or closed to the request source IP.

    • Each Gateway constantly updates Massbit Core to maintain a list of verified Node in its zone. From the gateway, the request is then forwarded to one of the nodes in the same zone in a round robit fashion. A node will will then relays the request to the blockchain data-source associated with the node.

    Massbit routing mechanism

    • When a node or gateway experiences issues such as poor CPU, memory, and network performance which result in high latency and response time, it will be deregistered from the Massbit network by Fisherman. Only nodes with "staked" status in the Massbit network can serve API requests and earn token rewards to guarantee the stability of the entire network.

    • Because Massbit Gateways, Nodes, and blockchain source nodes are operated by independent providers, single-point of failure is eliminated. Fisherman ensures DNS entries of offline or malfunctioned Nodes and Gateways are removed from the network and make sure blockchain requests are forwarded through active nodes, which maintains redundancy for the Massbit network.

    Node Approval processโ€‹

    Node Aprroval process

    When a Node or Gateway joins Massbit, it needs to go through different states before it can serve dAPI traffics.

    • Created: Node/Gateway information (name, zone, blockchain type that is served by this node, blockchain node IP) is registered with Massbit network. Based on the registered information, an installation shell script is generated for the new node.

    • Installing: When the installation script is executed on a new server that needs to join the Massbit network, the status changes to Installing, and the public IP of Node/Gateway is recorded to the Massbit chain

    • Verifying: When the installation completes on the new server, it will proceed with the verification process for eligibility to join the Massbit network. Fisherman will be mainly responsible for this stage by checking the following criteria:

    CriteriaDetail
    Data integrityThe node/gateway must return data identical to the blockchain data-source from which the response was retrieved. This will prevent man-in-the-middle attacks
    The blockchain data-source must be fully synchronized.
    PerformanceNode/gateway needs to satisfy 3000 requests/sec with a 500 MB/sec transfer rate for 95% of test requests

    • Verified / Failed: If a node/gateway passes Verifying stage, it becomes "Verified" and is ready to be approved by Fisherman for staking and serving dAPI

    • Approved: In each zone, based on the dAPI demand, Fisherman automatically will approve the node/gateway to join Massbit.

    • Staked: After the node/gateway gets approved, the Node Provider needs to stake a minimum of 100 MBT tokens. Once the node/gateway is staked, it is ready to service the dAPI and earn token rewards.

    • Reported: While nodes/gateways are servicing the network, Fisherman continuously checks for the network stability of each node/gateway. In case a node/gateway does not pass the check, it will be reported and eliminated from the Massbit network.

    How does Massbit make sure that the nodes actually fulfil the Performance requirements?โ€‹

    • In Milestone 1, we place Fisherman in each regions to check the network performance of new Nodes/Gateways before joining Massbit network. By measuring Rount Trip Time and network bandwidth from it self to the new Node/Gateway, it makes decisions whether the new node is eligible for joining the network.

    • We are aware that this approach has many drawbacks and the evaluation proccess is not fair for all new nodes. The first version of Fisherman is a prototype for us to test the functionality of all Massbit components together.

    • In Milestone 2, Fisherman is modified to be more decentralized and more efficient. All Massbit Gateways have Fisherman component included, which is responsible for ensuring the neighbor Nodes and Gateways are functional. Each Fisherman talks to a Scheduler in its region and perform assgined tasks.

    1. When a Node/Gateway needs to join Massbit network, the Schedulers requires all active Gateways in the network to measure Round Trip Time (RTT) and network bandwidth to the new Node/Gateway.
    2. Based on the result of RTT and network bandwidth from active Gateways to the new Node/Gateway, if they satisfy the RTT and network bandwidth baseline, the new Node/Gateway is verified. The Node Provider can stake the new node with MBT tokens and serve traffic. In case of a new Node, it also needs to be able to forward test RPC requests to its attached blockchain datasource and returns back valid RPC response.
    3. Once the new Node/Gateway is staked and actively serving traffic, the Scheduler will inform the Massbit Core to update the network configuration for the whole network with the new node. Based on measured RTTs and network bandwidth measure from each active Gateway to the new Node/Gateway:
      • The new Gateway will receive a new network configuration to pair and forward traffic to low latency/nearby existing Nodes
      • The new Node will receive a new network configuration to receive traffic from nearby Gateways
    4. The previous process will repeat periodically to update Gateway and Node pairings with the most optimized paths and make sure the new Node/Gateway remain functional in the Massbit network.
    • The specific values for ideal RTT and network bandwidth are to be determined as Massbit team needs to perform more benchmark and testing for further evaluation.
    • The Scheduler is designed to assign multiple checks/tasks to Fishermans on active Gateways. Depend on our findings, more tasks may be added after our internal testing and during testnet phase.

    How does Massbit system deal with denial-of-service (DDoS) attacks?โ€‹

    • Malicious actors will find a way to disrupt Massbit network in order to cause outage and interuption for Web3/DApp. For Massbit Gateways and Nodes, the only required open port is 443 to minimize the attack surface to Massbit network. What counter-measurements does Massbit implement to prevent this problem?

    • Massbit Route is designed as distributed network of Nodes and Gateways. As Massbit network grows in the number of Nodes/Gateways in 6 different regions, high network load is scattered across different paths to reach a specific blockchain RPC node, which will reduce the network congestion and mitigate the effect of DDOS attacks.

    • Protection at Node level:

      • Massbit nodes only need to receive traffic from nearby Gateways with low RTT and high network bandwidth. For that reason, HTTPS connections are only whitelisted for those nearby Gateways.

    • Protection at dAPI level:

      • Attacker can obtain Massbit dAPI URL from Web3/DApps source code and perform volume-based DDoS at Layer 7 on the URL with the desire of saturating the bandwidth of the whole network. Each Massbit dAPI created has a default rate limiting configuration of 100 requests/sec which is applied on all Gateways that will be serving traffic for the specific dAPI URL. The consumers can adjust this number from the Web Portal based on their usage.

      • When the dAPI URL is called, the traffic is handled by a Gateway which is in the same zone as the requester's source IP. If the DDoS attack is lauched from many different botnets in a single or multiple Geo resgions to the dAPI endpoint, their traffic is served by multiple Massbit Gateways, which mitigate the impact of high-volume traffic. Once the request/sec threshold reaches on a Gateway, it start to refuses subsequent incoming requests. As a result, Massbit Gateways prevents volume-based DDoS traffic from entering Massbit network, and reaching underlying Massbit Nodes/RPC nodes. The more Gateways are deployed across regions, the better Massbit network sustain volume-based DDoS attack

      • The Fisherman component of the nearby Gateways periodically check its neighbor for liveness, and inform Massbit Core to update the routing/DNS configuration for the entire network to instruct healthy Gateways to serve incoming RPC requests within a zone. If a Gateway's resources are overwhelmed and can no longer serve request due to DDoS protocol attacks such as SYN flood, or IP spoofing, Massbit Core updates with Gateway Manager to stop resolving the host portion in the dAPI URL to the unhealthy Gateway. This will add redundacy and ensure Massbit network remain functional in the event of some Gatways are taken down due to DDoS attack.

      • The attacker can also create multiple Massbit dAPI entries to increase the attack surface, and amplify the magnitude of the attack. In order for the attacker's volume-based network traffic to penerate into Massbit network and reached Massbit Nodes and RPC nodes, they will need to deposit MBT token to their Massbit dAPI and receive a specific quota according to the deposit amount. If the dAPI quota reaches 0, Gateways stop serving traffic for the dAPI URL. This also discourage the attacker as there is cost involved in launching the attack, and the Node Providers earns reward for maintain the network.

    • Protection at Gateway level:

      • The attacker can focus on a specific Gateway IP and perform a direct DDoS attack without using the dAPI URL.

      • At Layer 3 and 4, monitoring network health and anomaly detection is one of our team's primary focus for DDoS mitigation strategy. Each Gateway and Node will be installed with a monitoring client which will report network statistics, network flow and top talkers. Known DDoS attack patterns are rejected and alerted to our internal team's monitoring service with pre-configured patterns/rules such as certains IPs causing peaks in network, open connections and resource depletion.

      • Additionally, based on our observation, we can also implement a new traffic configuration policy, and allow Massbit Core to update the entire network of Massbit Gateways/Nodes to defend against malicious DDoS traffic. DDoS protection at Layer 3/4 for Massbit network is a challenging task with unexpected and sophisticated threats, so we will have to take both pro-active and re-active approach to keep the network healthy.

    • Other counter-measurements:

      • Gateway Manager is also a crucial part of Massbit network as it the authoritative DNS component of the network. DNS components are prone to reflection and amplification attack, which accelerate the rate of malformed traffic to deplete the server resources. We will utilize existing third-party service with Deep Packet Inspection capability, DNS query whitelisting and rate-limiting to add a layer of defense and DDoS mitigation to this component.

      • Massbit Core and Massbit web portal are also placed behind a Web Application Firewall and Layer 3 Network Firewall to protect against DDOS and common web application attacks.

    Tokenomic of MBTโ€‹

    • MBT tokens will be used within the Massbit network by Node Providers, dAPI Consumers, and Delegators. In order to join the Massbit network, Node Providers need to stake their Massbit Nodes and Gateways to become actively serving blockchain requests in Massbit. In return, Node Providers will receive MBT token rewards from serving requests from dAPI Consumers.

    • The Consumers need to deposit MBT tokens to exchange for dAPI usage quota. The deposit amount is distributed to the Nodes Providers based on the amount of dAPI requests they served after each Era.

    • In addition, anyone can delegate MBT token to actively running Massbit Nodes/Gateways to earn a small portion of the reward without the technical knowledge and effort to maintain Nodes/Gateways and RPC nodes.

    • Our team is still expanding more detail for the Massbit token economy, which can be found in the this documentation

    Ecosystem Fitโ€‹

    • Massbit Route is a decentralized network of Nodes and Gateways that route dApps requests to low latency blockchain nodes. Built on Substrate framework, we would like to create a diversified network of independent blockchain RPC nodes and Web3 applications that are servicing each other.

    • Within the ecosystem, by using Massbit tokens, independent individuals, groups, communities, or organizations can freely join and get reward for servicing the BDN network by running Node/Gateways. With Massbit Route dAPI, Web3/DApps will have reliable and cost-efficient access to a independent blockchain RPC nodes through Massbit routing and caching mechanism. There is no middle-man or single entity that controls the entire blockchain distribution network which will eliminate the majority of undesired service interuption or censorship that may happen.

    • With a foundational software design and network routing structure of Massbit Nodes and Gateways, the upcoming integration with more layer-1 protocols, ETH layer 2 solutions, and other parachains become less of a burden in the near future. Once our team sees a demand for a new type of blockchain in the Massbit Route network, the implementation for the new blockchain integration can be done in a short duration. Our team commits to listen and support our community's needs to enrich the ecosystem and maintain the stability of the Massbit network.

    Development Status ๐Ÿ“–โ€‹

    • Massbit Route team has completed the code base for the Massbit Route blockchain distribution network including:

      • Core API
      • Stats
      • Session manager
      • Fisherman and Verification service
      • Gateway Manager
      • Massbit Node
      • Massbit Gateway

    • Through a network of Massbit nodes and gateways, Massbit Route is now supporting traffic routing to ETH and DOT blockchain nodes. We have tested the network internally with 150 Massbit nodes and gateways deployed in 5 zones. We came to the conclusion that, in each zone, each working Massbit node requires 4 Massbit Gateway to achieve a reponse time under 500 ms for a blockchain API request through dAPI entry-point.

    • Currently, we are in Testnet with a target of 100 independent user-operated Massbit nodes (each node attach to an ETH/DOT full node) and Gateways that span across 5 different zones. Through this testnet phase, we would like to introduce Massbit Route core functionality to professional and individual node providers as well as dApps partners that need cost-efficient and fast access to ETH/DOT blockchain nodes. Additionally, we take this opportunity to object real-world network traffic/usage to evaluate the following key points for further improvement in preparation for main-net launch:

      • The effectiveness of the blockchain traffic routing mechanism
      • Find out key metrics to adjust the fairness for the node approval process
      • Adjust the fee for dAPI usage and fair reward distribution to node providers who served the API request

    Future Plansโ€‹

    • Our testnet phase is currently open to let our community experiment with Massbit Route core routing functionality with ETH and DOT blockchain nodes. Within the scope of Milestone 1, we want to take this opportunity to observe the following to release the stable version of the Massbit Route blockchain distribution network:

      • User experience with Node/Gateway installation process
      • Node approval process with a fair evaluation of RTT and network bandwidth by distributed Fisherman component at different locations within a zone
      • Accuracy in IP Geolocation for Nodes/Gateways
        • This ensures Nodes/Gateways are approved and benchmarked by Fisherman in the right zone
        • Detect inaccuracy in IP Geolocation database by surrounding gateways

    • In the short term, we put our effort into optimizing and improving the efficiency of core functionalities of Massbit Route. We will open testnet with unofficial Massbit token to allow active community members to experiment with the Massbit Route network. This also helps our team to patch any bugs or issues from the design and implementation from the Node Provider standpoint.

    • Once Massbit Route achieves the stability and efficiency at the early stage, it will have a solid foundation to attract DApps to migrate to Massbit Route API and more Node Providers around the world to come and service the network. DApps and strategic partners are onboard and offered to use dAPI from Massbit Route launched testnet. We will collect feedback/performance metrics and improve the product from End-user/Consumer standpoint.

    • In the long run, once we reach the stability of global Massbit routing performance and fair token distribution from Consumers deposit fees to Node Providers, we will focus on expanding the Massbit Route ecosystem by integrating the network with parachains and major L1/L2 that have a large number of transactions and data usage. In addition, when we reach a large network of node providers that span many different parts of the world and have quick access to mempool, it is a good opportunity for Massbit to expand the feature scope to Defi Trading such as determining the gas price to win a gas auction or future block mining.

    Mobile Game Framework for Substrate

    • Proposer: enfipy
    • Payment Address: 1Gkvai1HtZmtQ5DWDGrCwarKHh4SErAufe

    Project Description ๐Ÿ“„โ€‹

    We want to make it simple to create and build Android and iOS game projects and connect them with Substrate blockchain. Currently, setup build of rust game project with basic requirements (like 2D/3D rendering, sounds, touch events, textures, etc) for iOS and Android is a pretty hard task. So a lot of developers don't start projects on top of rust-lang game engines because of uncertainty that they will be able to publish them to Google Play and App Store. We want to change this situation and make sure that anybody will be able to create, build and publish their mobile games to the marketplaces. Make this process simple yet reliable.

    Also, we are extremely excited about decentralized games and what kind of games can be created with this idea in mind! Substrate blockchain framework is ideal for this as it can provide forkless updates, smart contracts, light client and so much on. We plan to create a setup for mobile development first, build a Substrate light client in mobile app and connect it to Substrate full node (or make a connection via JSON-RPC). Make sure that we can subscribe to data and send extrinsics to any Substrate based network. So that anybody from community of Polkadot will able to create own game projects, build for mobile platforms and publish them.

    There are already plenty of interesting game engines made with rust-lang (e.g. Piston, Amethyst, BevyEngine. But we don't want to make it possible to build only with one specific rust game engine so we will do this framework game engine agnostic as much as possible.

    Pros for Polkadot Ecosystem:

    1. We will setup mobile development environment - community of Polkadot will be able to create own mobile game projects on top of it. This is also very useful for rust game development community.
    2. We will create integration and communication with substrate node and make sure that it runs on mobile platforms flawlessly.
    3. The community of Polkadot will be able to set up their own substrate-based game projects in a matter of minutes.
    4. The first decentralized mobile game on top of the Substrate.

    After the finish of this project, our team wants to create a mobile strategy game with all backend logic in Substrate. So this project important step forward decentralized mobile game on top of the Substrate.

    Polkadot/Substrate dApps/Wallet Connection using Tesseract

    Project Descriptionโ€‹

    The goal of this proposal is to enhance the usability and security of Polkadot/Substrate native mobile applications (the ones in AppStore and Play Market). By enabling the apps to connect to the wallets when a signature for a transaction is needed, we propose to get rid of a cumbersome and potentially insecure private key handling burden.

    To achieve this goal, we propose to implement Tesseract (dApps/wallets connection) protocol for Polkadot/Substrate.

    Why Tesseract is good for the ecosystemโ€‹

    iOS and Android are (arguably) the most popular app platforms today. With smooth experience and high security provided by Tesseractโ€™s capability to eliminate private key handling, the dApps could more easily match the expectations of an application from AppStore or PlayMarket, thus leading to lesser friction in dApps adoption.

    How Tesseract integrates into Substrate/Polkadotโ€‹

    Once implemented, any Polkadot/Substrate native mobile dApp developer will be able to add Tesseract support with just several lines of code.

    As an example, this is how our integration currently works in Swift for the Ethereum network:

    import Tesseract

    // Check that we have a wallet installed. You should handle this situation in your app.
    guard Tesseract.Ethereum.isKeychainInstalled else {
        fatalError("Wallet is not installed!")
    }

    // Our HTTP RPC URL. Can be Infura
    let rpcUrl = "https://mainnet.infura.io/v3/{API-KEY}"

    // Creating Web3 instance. Try to reuse the existing instance of Web3 in your app.
    let web3 = Tesseract.Ethereum.Web3(rpcUrl: rpcUrl)

    For more information, please check: https://github.com/tesseract-one/Tesseract.swift

    Our current implementation of the reference wallet for iOS, supporting Ethereum can be found here: https://apps.apple.com/us/app/tesseract-wallet/id1459505103. We plan to approach Tesseract supporting Polkadot wallet with a consequent separate proposal. Itโ€™s either going to be a reference wallet implementation or integration with some existing Polkadot wallets.

    How is Tesseract different?โ€‹

    Since the deliverables of this proposal are mobile-specific, but Tesseract is so much more than just a solution for mobile dApps and weโ€™d like to share this aspect as well. We've split this section into two parts: the first answering the question specifically about mobile and the second covering a more general comparison of Tesseract's approach.

    How is Tesseract different on mobile?โ€‹

    The short answer to this question is that Tesseract can provide a potentially more familiar mobile UX due to deeper integration with the underlying OS, by utilizing OS native IPC (Inter-Process Communication) protocol.

    To demonstrate the advantages of our approach, letโ€™s first briefly cover the other options available:

    • Key inside the dApp - not really an external signature provider, as the app manages the private key inside. Worth mentioning, as quite a number of native mobile dApps use this approach. The user just has to copy the private key into the dApp. Simplest, but raises security concerns and the usability is questionable.
    • Centralized proxies - centralized custodial wallet solution for decentralized applications. Example: Fortmatic
    • URLs (aka deep-linking) - allows jumping between applications on smartphones using special URLs. This way a dApp can switch to the wallet by forming a request in a URL form and receive a response from the wallet switching back the same way. This approach works to a limited extent, suffering from routing problems (especially on iOS) and canโ€™t support multiple wallets without a 3rd party router (or a maintained list of supported wallets matched to their unique URLs). On iOS, if more than one application can open a URL, the app is chosen randomly which rises a security concern. From the UX standpoint, it looks like the apps are switching back and forth. Deep-linking is sometimes used together with relays (see below).
    • Centralized signing relays - allows a mobile wallet to sign transactions using centralized servers as connection relays. Usually works together with a deep-linking handshake, inheriting its issues and behavior (iOS routing issues, app switching UX). Also, such a solution canโ€™t be considered optimal, due to the fact that two apps running on the same device have to communicate through a server somewhere on the internet. Examples: WalletConnect, WalletLink
    • Decentralized signing relays - this approach works similarly to Centralized signing relays, except that p2p mesh is used instead of a centralized relay server. Examples: Beacon

    In contrast, Tesseractโ€™s transport on smartphones is based on another technology, deeply integrated into the underlying OS - inter-process communication (IPC). This way we have managed to achieve a convenient UX. The behavior is centered around modal screens, which are quite widely used in various applications (please, check our demo: https://drive.google.com/file/d/17YMdJS9CH6SXqP-YPUMKbm0BWdAE2Rx3/view). There is no central authority and the data goes through the shortest route - communication is done point to point between two processes running on the same device. It works equally well on both iOS and Android without any dApp/Wallet routing issues (the user can pick the wallet to use for a signature). As for security - after extensive testing, we have not found any ways to hijack a transaction so far.

    The table below summarises our comparison considerations, demonstrating why we have decided to utilize the IPC protocol instead of something else:

    How is Tesseract different beyond mobile?โ€‹

    Tesseract protocol was designed adaptable to existing and new potential use cases through flexibility provided by multi-transport (IPC, socket, QR-code, etc.) architecture, in contrast to its single-transport protocol counterparts. While some transport protocols can shine in one scenario, a totally different approach may be needed for another. There are a number of known (and probably quite some yet-to-be-discovered) use cases of how dApps and wallets may need to interact. Some common examples are:

    • A dApp and a wallet run on the same smartphone
    • A dApp and a wallet run on the same desktop
    • A dApp runs on the desktop and a wallet runs on a smartphone
    • etc.

    Here is a short table, that summarises the comparison of some common transport protocols versus the use cases. While there are way more use cases than the table covers, the ones included are sufficient to showcase that neither transport is capable of covering all the use cases by itself. Also, here we show only transports that are not compromising decentralization.

    Since none of the transport protocols are universal enough to be an optimal choice for every use case, weโ€™ve designed Tesseract to be non-constrained by this factor. Instead, Tesseract can use any implemented transport protocol, based on the scenario and/or the userโ€™s choice, due to its layered architecture. The following diagram demonstrates a simplified architecture of the Tesseract protocol:

    Architecture of Tesseract

    This way, Tesseract can potentially handle any known or future use case to the extent the most matching transport can, which is not an available option for the single-transport bound solutions.

    Why our Team is interestedโ€‹

    As we indicated in our first proposal, which was awarded and currently coming to the end (Swift API), that our long term goal was to bring Tesseract support to the Polkadot community.

    The Swift API library from our first proposal was an essential step for us, as Swift is the programming language of iOS and we need this to implement Tesseract support for Polkadot/Substrate on iOS. Since we are finishing with the first grant application, we have prepared the current proposal to continue the integration process of Tesseract into Polkadot/Substrate ecosystem.

    Tesseract Overviewโ€‹

    The main goal of the Tesseract protocol is to enable dApp developers to provide a smooth and easy-to-understand user experience without compromising privacy and decentralization. Being a protocol that allows dApps to run without having access to the user's private key, Tesseract facilitates communication with the Wallets to request transaction and data signatures, thus providing a possibility to get rid of private key handling and having a look and feel of a โ€œnormalโ€ application.

    Before digging into the technical details, we want to share the โ€œfeelโ€ of how the Tesseract-based dApps work: https://drive.google.com/file/d/17YMdJS9CH6SXqP-YPUMKbm0BWdAE2Rx3/view.

    Such a user experience is achieved by having a seamless connection between the dApp and the wallet via Tesseract protocol.

    Even though mobile is the first focus, Tesseract is not limited to being the mobile-only solution. It can maintain the connection between dApps and wallets working in various environments: smartphone, desktop, or even crossing the border of a single device (i.e. a dApp runs on the computer and the wallet is on the smartphone). This is achieved by having a layered architecture, that depending on the current environment, allows using a suitable transport protocol.

    Tesseract protocol does not require a server to keep the keys. All the requests are done directly to the wallet application through IPC (if the device is the same) or other p2p communication protocol (if cross-device).

    Tesseract Architectureโ€‹

    Tesseract protocol is designed from the perspective of flexibility to make it adaptable for various scenarios. To achieve this goal, Tesseract uses a layered structure in its core and messages, that are enveloped according to the protocol layer.

    The layers-based implementation is largely inspired by the OSI model (the model of network protocols).

    Layered structureโ€‹

    As mentioned above, Tesseract has a layered structure. The basic three layers are:

    • Application Layer - responsible for communication via specific protocol (i.e. Polkadot): transaction signing request, messages signing, public key requests - all here.
    • Presentation Layer - provides enveloping of application-specific data into transportable packages. Defines text/binary packet structures transferrable via any underlying transport.
    • Transport Layer - implementation of various transport types. IPC, p2p NFC, URLs, QR-codes, Bluetooth, etc.
    Application Layerโ€‹

    The application layer can be anything, depending on the specific network plus Tesseractโ€™s application-layer protocol for controlling connection establishment, checking the presence of other application-layer protocols, etc.

    Tesseract application-layer protocolโ€‹

    Tesseractsโ€™ application layer API is responsible for the following:

    • Checking the presence of specific application-level protocol extensions
    • Event subscription
    • Inter-device connection initialization
    Polkadot application-layer protocolโ€‹

    This is the part where Polkadot gets integrated:

    • Signing data
    • Signing transactions
    • Public key querying

    From the perspective of the dApp developer - nothing changes. The developer still uses the same familiar Polkadot APIs. The only difference is that when Tesseract is integrated as a signature provider, the transactions are rerouted to an external wallet for signing, and then sent back to the dApp.

    Presentation Layerโ€‹

    The presentation layer defines how the data is enveloped to be properly delivered to the destination. The current implementation uses JSON text messages (the easiest to debug and has great support in various platforms). Binary is a future consideration.

    Transport Layerโ€‹

    This layer is what makes Tesseract so flexible and allows it to work in various environments. It determines how exactly the dAppโ€™s requests packets are transferred to the wallets and how the wallets reply. By having multiple options of the transports, the dApps can communicate to the wallets located anywhere: on the same device or not. Communication between devices can be pretty much anything that can transfer data (TCP/IP, Bluetooth, NFC, etc.). For the current proposal though, we want to limit the number of transport layers implementations to the following:

    • iOS IPC
    • Android IPC

    By implementing the above transfer protocols, we already allow developers to create native mobile dApps that donโ€™t have to carry a private key. While more protocols bring more value, this way we can release the first version sooner and go to market sooner with a concrete value proposition.

    In the future, we plan to implement protocols that allow inter-device communication. Possible options for the near future include:

    • QR codes/(NFC) - mainly for a persistent connection initialization, especially in trustless environments
    • WebRTC - potentially the best option for browsers
    • TCP/IP - easier to implement for desktop apps then WebRTC
    • Bluetooth - browsers/between devices

    Tesseract Implementationโ€‹

    The implementation of Tesseract, pretty much like any other protocol, is a set of libraries that allow applications to communicate through it. In the case of Tesseract, there are two sets of libraries: one for the dApps (allows querying the wallets) and one for the Wallet (allows replying to the signing requests).

    Currently, Tesseract has a partial implementation in Swift and works on iOS: https://github.com/tesseract-one/Tesseract.swift.

    For the sake of having a single cross-platform implementation (fewer bugs, single codebase), we propose to implement it in Rust and add language-specific wrappers in the future (i.e. Swift, Java, ReactNative, etc.).

    For the details on the proposed implementation, please refer to the Development Roadmap section.

    Future Plansโ€‹

    The long-term vision for Tesseract is to be a safe, secure, and user-friendly way for any application to access a userโ€™s wallet and private keys, on as many blockchains as possible.

    At the moment, though, we want to bring the details about the next short-term steps, that we believe are essential for the project to start bringing traction.

    The next immediate step is making the use of Tesseract protocol easy for the Polkadot developers, which requires integration with the ecosystem. Specifically integration with:

    This will enable Mobile developers to start using Tesseract without any additional tools switching. Just adding a couple of lines of code for initialization.

    Simultaneously, we are going to deal with the wallet side by either providing a reference wallet implementation or by integrating with the existing Polkadot wallets (TBD).

    Conclusionโ€‹

    The quest for a better dApp signature provider is not new and there are quite some approaches. All the solutions have their pros and cons, but none are universal, secure, and decentralized at the same time.

    Tesseract was designed with the idea that itโ€™s not enough to solve one of the problems or to provide a limited number of use cases. We believe that to break the dApps adoption barrier, there must be a solution that is universal, secure, usable, and decentralized at the same time.

    Project Descriptionโ€‹

    When we developed and used the multi-signature feature, we found that there is no multisignature wallet tool that can be used conveniently. The current wallet project is mainly designed for different usage environments, such as mobile wallet app, web wallet, chrome extension, etc. The development of these wallets (except the polkadot.js app) is at an early stage, and lack of multi-signature module . Polkadot.js apps is a very powerful tool, however the user experience and interface of substrate's native multi-signature module integrated in polkadot js is not friendly enough.

    Therefore, we want to develop a Web Multisignature Management Tool (like gnosis based on Ethereum), implement a Substrate multisignature Portal and Web Tool integration, and bring users a better experience. Besides, subscan will support multisig Extrinsic details display. At current stage, our goal is offering users have a convenient multisignature tool and helping developers reduce the development cost of similar functions.

    • Network scalability

    All chains built on substrate as_multi module can use our tools to complete related operations directly. The chain that changes the as_multi module can use our UX design partly or completely according to their needs to reduce the development cost.

    • Platform scalability

    The web Multi-signature Management Tool can only run on PC and use it with extension programs.

    Objectivesโ€‹

    • Create multi-signature account and send extrinsic
    • Manage multi-signature wallets and extrinsic
    • as_multi Module subscan browser adaptation
    • Support multiple networks that are based on Substrate development
    • UX optimization

    Project Overviewโ€‹

    Overviewโ€‹

    MyBank is a decentralized financial platform based on Polkadot, aiming to establish a blockchain network that realizes asset appreciation and promotes asset flow. MyBank is divided into four parts: Platform Bank, Social Network Bank, MyDeX and Credit Scoring System.

    • In Platform Bank, users can participate as depositors, borrowers, and guarantors. Depositors can obtain deterministic returns by injecting liquidity into the corresponding asset pool. Borrowers can borrow by mortgaging collateral or invite guarantors to guarantee them to make zero-mortgage loans. After the implementation of the credit scoring system, credit loans without collateral or guarantee will be supported based on the user profile.

    • In Social Network Bank, MyBank as an infrastructure platform provides corresponding tools so that any individual and organization can build a collective bank that belongs to all members of a social network.

    • MyDeX aims to provide users with the service of AMM, and support users to participate in the liquidation of Platform Bank.

    • We will develop a credit scoring system based on users' deposit records, loan records, guarantee records, transaction records, social networks and third-party data to generate user profile.

    Project Detailsโ€‹

    Platform Bankโ€‹

    Most DeFi lending products are based on the mortgage system. Users lend assets from the asset pool by mortgaging collateral. We try to go further on this pattern. While providing mortgage lending services, we will release the liquidity of the depositor's assets and provide zero mortgage services. Depositors can use their deposit certificates to guarantee loans for friends, and friends can make zero mortgage loans on the platform based on the guarantee certificates. During the guarantee process, the guarantor's deposits will continue to generate income and will not be affected.

    Each user will maintain a social network circle of their own, and the friend relationship needs to be confirmed by both parties. When a user has a loan demand and wants to choose a zero-mortgage loan, he can send the loan event to his friend's inbox, and the friend can choose to respond to the event to guarantee him. After the guarantee is successful, the system will issue a loan to his friend, and the deposit certificate will be locked by the system. Before the borrower repays, unless the guarantor chooses to pay a certain amount of funds to redeem the deposit certificate, his deposit will not be withdrawn.

    image-20210429161048216Platform Bank supports multi-currency digital assets as collateral for loans or guarantees. Each type of asset corresponds to different risk parameters according to its risk coefficient. In the future, MB Token holders can vote on the adjustment of the parameters, and the proposal passed by the referendum will be automatically executed by substrate runtime.

    • Liquidation Ratio Each loan that occurs in the PB will correspond to a collateral-to-debit ratio. Each type of asset will have a corresponding liquidation ratio according to its market value and volatility, and the system will monitor the collaterals-to-debit ratio of each loan. Once the collaterals-to-debit ratio is lower than the liquidation ratio, it will trigger liquidation behaviour. Assets with a higher risk coefficient usually correspond to a larger liquidation ratio and vice versa.

    • Interest Rates Determine the annualized rate of return of depositors, the borrowing cost of borrowers, and the size of the asset pool, and at the same time affect the risk of the system. The interest rate is determined by supply and demand. When the utilization rate of the asset pool is low, users will be encouraged to borrow through low-interest rates. When the utilization rate of the fund pool is high, the interest rate will increase to encourage users to repay the loan and attract depositors to provide liquidity to the asset pool through higher yields. Each asset pool will set a critical point, and the loan interest rate will increase faster after the utilization rate of the asset pool exceeds the critical point.

    • Insurance Fund MyBank has set aside a part of MB Token as insurance funds. When the Black Swan incident causes unexpected situations, MyBank will take part of the assets from the insurance fund to compensate users for losses. MyBank will charge depositors a certain percentage of handling fees and this part of funds will be combined with insurance funds.

    We will expand Platform Bank to support credit loans. The user's social networks, deposit records, loan records, guarantee records, and transaction records will all be stored on the chain to form an anonymous credit scoring system. The credit data accumulated by users combined with off-ch governance has brought the possibility of developing credit loan business. Credit loans need a strong governance organization, relying on the relevant identity authentication system and legal system. In the first stage, the credit loan business will be launched through the Private Pool and will only be open to financial institutions and enterprises that have passed the off-chain review.

    Institutions can also pay a certain fee to create an independent Private Pool to develop loan business based on the infrastructure provided by MyBank. For example, the identity on the chain is an anonymous hash address. With the user's permission, the institution can verify the user's identity under the chain, and combine the credit score record to decide whether to issue a credit loan or mortgage loan to the user. The loan contract will be written to MyBank's distributed ledger. Loan records incurred by Private Pool can also be synchronized to the credit scoring system.

    img

    Social Network Bankโ€‹

    We try to integrate the advantages of blockchain, social network and collective governance to establish a brand-new collective bank to improve the utilization rate of funds and realize inclusive finance. Anyone can build a digital bank of their own through the blockchain infrastructure provided by MyBank. The bank will be governed by the users and MyBank will not intervene. The governance of each bank will be the responsibility of all users of the bank. As a bank based on social networks, members have real social relationships under the chain.

    Members can contribute deposits to the bank. The more deposits, the greater the contribution to the bank. Deposit contributions will be recorded on the chain, and depositors will not only gain wealth but also reputation. The deposit records contributed by members are visible to other members. In the future, when they need loans, loan applications will be easier to pass. The more people they helped in the past, the greater the probability of getting help from others in the future.

    Repayment of a loan will leave a record on the chain. Borrowers will have a greater chance to obtain larger loans in the future, indirectly encouraging users to gradually accumulate their credit history. All behaviours will be recorded on the chain. Based on the external constraints of social networks, the default will affect the reputation of individuals in the real life. And borrowers will not be able to obtain loans from the bank in the future or it will become more difficult to borrow. Loans can be based on joint and several liabilities. If a person fails to repay the loan, the credit history of the members who guarantee or vote for it will also be affected. It may be regarded as a default, so the borrower's friends have an additional incentive to help the borrower.

    image-20210430143053169

    MyBank abstracts the user's demands into corresponding events, and the event is decided by the collective or the committee. Users can set the governance of the bank by themselves.

    Users can select a committee to govern. The committee members are elected by all members, and all members also have the right to initiate a referendum to remove a committee member. The management of the bank will be fully represented by the committee, and each event requires the consent of a certain proportion of the committee members before it can be executed. The event approved by the committee can be an automatic event, or it needs to be executed after a while. If all members reject the event by referendum, the event will be automatically removed. The committee member can choose to pledge a certain amount of assets to obtain more nomination votes. If the committee member acts against the interests of other members of the bank, other members can initiate a referendum to confiscate the pledged assets of the committee member.

    Users can also choose collective governance. Each event requires the consent of a certain proportion of all members before it can be executed. Or users can combine the advantages of committee governance and collective governance to conduct mixed governance, and choose a balance between efficiency and democracy. For example, a loan event requires a collective decision, and a deposit event can be decided by the committee.

    MyDeXโ€‹

    Any user can inject funds into the asset pool to obtain the transaction fee income. The equation for working out the price of each token is x*y=k, where the amount of XToken is x and the amount of YToken is y. K is a constant value.

    At the same time, users can pledge the LP Token to become a liquidator in Platform Bank, and can easily capture the income brought by liquidation while obtaining the transaction fee income. When the liquidation is triggered, the borrower needs to pay a certain percentage of the penalty fee, and the liquidator will receive this penalty fee.

    img

    MyDeX will integrate with Platform Bank to make it easier to short or long.

    • If a user is not optimistic that XToken will continue to rise in the future, he can choose to lend XToken at Platform Bank, then sell XToken in MyDeX to obtain stable coins, and redeem XToken to repay the loan when the price falls.

    • If a user is optimistic that XToken will continue to rise in the future, want to leverage. He can lends stable currency in Platform Bank, and then use the stable currency to obtain XToken in MyDeX, and sell XToken to redeem stable currency to repay the loan when the price rises.

    On the current Ethereum platform, if the above two operations are to be carried out, users need to jump and click multiple times between multiple DeFi products. On the front-end interactive page of MyBank, the above-mentioned operation users only need to click once, and the whole operation will be completed in one block, which is more convenient and has a faster execution speed.

    Credit Scoring System Explanationโ€‹

    Human beings are the total of social relations, and we should create a credit score system that does not need a third party or a central institution but is based on individual social relations.

    The structure and location of human networks determine everyone's choices in making friends, choosing schools, employment, financial management, raising children, leisure and entertainment. They also determine people's social circles and beliefs, as well as who is more powerful and influential and more likely to be successful. We quantified a personโ€™s 'position' in social networks, combined with a continuous "Proof Of Vote" to establish a completely digital blockchain credit system.

    Unlike trust models such as EigenTrust, the trust system is based on the fact that we can use homomorphic encryption to achieve anonymous scoring of any individual in social networks; and a person's centrality, eigenvector centrality, propagation centrality, intermediary centrality, etc. are used as weight factors; Burn mechanism of Coindays is used as another set of main credit evaluation factors.

    Anonymous Voteโ€‹

    In an interpersonal network, we should directly express our likes and dislikes, and should not be affected by identity, status, skin color, wealth, etc. In addition, we should digitize it and show it to the newly joined individuals in an intuitive way.

    Homomorphic encryption provides the technical foundation. Each vote will consume a certain amount of MB, and the cost of the vote will be directly related to Token, which will affect the opportunity to obtain Token in the future. We use the Burn mechanism of Coindays as a credit evaluation factor. In a vote, the value of destruction is positively related to the weight of the credit evaluation. When two accounts are trying to repeatedly trade to obtain the score of this weight, the first evaluation is valid, and at this time the accumulated Coindays have been destroyed. When the second vote is conducted, the accumulation of Coindays will be very small because it occurs shortly after the first transaction. Correspondingly, the contribution to the credit evaluation is very small, but a certain amount of MB tokens will be consumed as a handling fee. Similarly, when there are possible malicious bad reviews, because the credit evaluation is proportional to the destruction of Coindays, the amount of the transaction is too small, and it can hardly affect the user's credit.

    Social Locationโ€‹

    Social networks are different from other networks. We measure a person's position in society. At present, it mainly includes the following five aspects:

    1. The number of friends. We have created a new relationship network on the chain. To establish such a relationship, we need the consent of the other party and pay a certain fee. The existence of a hash algorithm naturally helps us avoid network storms. For possible abuse, we combine social science research similar to "Dunbar number". After the number of friends reaches a certain threshold, the cost will be greatly increased. Centricity is used to measure this indicator.
    2. The number of friends with high scores. Real-life experience tells us that it is necessary for a person to have many friends, and it is more important to have higher-quality friends. Although a person may not have many friends, it is usually more useful to have some "powerful" friends. We use the term eigenvector centrality to measure this indicator.
    3. The trust score on the chain should be closely related to the activities on the chain. As an extension of the AMM function, we hope to spread the demand in social networks, and the spreading individuals can charge a certain handling fee and earn a certain interest rate spread.
    4. There is a cost to forwarding requirements. When there are more friends to forward your requirements to help you achieve your requirements, we believe that your role in your network cannot be ignored. We use the degree of communication centrality to measure this indicator.
    5. The role of mediation cannot be ignored. In fact, with smart contract, combined with the trust subsystem, anyone can act as an intermediary. When a demand can only be propagated and matched through this individual, this role is crucial to both supply and demand.
    Directionality Of Transactionsโ€‹

    Another use of Coindays is to establish the weight of trust scores assessed by transfers. Usually, we will deal with transactions as equivalent transactions. In a transaction, one party's expenditure is equal to the other party's income. This is no problem in itself, but in the world of digital, it is necessary to convert scalars into vectors. In the process of trading, the system's Coindays are always destroyed, and the original ordinary transaction.

    Similar lending products on Ethereum include Compound & Aave, and AMM products include Uniswap & Sushiswap.

    • In Platform Bank, we will release the liquidity of depositors' assets to maximize their social guarantee value and provide borrowers with zero mortgage loans service. After perfecting the credit scoring system, we will support users to make credit loans.

    • Platform Bank and MyDex are developed based on Polkadot and Substrate, and users will pay fewer transaction fees and get higher TPS.

    • Based on Polkadot's cross-chain bridge, MyBank can provide users with more diversified choices.

    • MyBank integrates lending and trading, abstracting it into an interface at the front end. Users can conduct leveraged trading with one click, making it more convenient to long and short without switching between multiple products to obtain lower transaction delay.

    At present, there is no similar product to Social Network Bank(SNB) in the market. SNB is not only aimed at the existing DeFi user group. SNB is an inclusive finance platform, allowing most people, including poor groups, to enjoy the convenience brought by finance and blockchain.

    • Most of the existing lending product is based on asset collateral, but many poor people in the world do not have enough assets to mortgage, so they cannot obtain loans from financial institutions. MyBank will provide relevant digital tools based on the blockchain, so that poor groups can help each other and supervise each other based on their social networks.

    • At the same time, we will cooperate with charities to provide start-up funds for the user's bank. When charities choose to donate to a poor village, after the initial distribution, some funds can be reserved for the user's SNB. Members in the same social network know each other better than third-party financial institutions. SNB can invest this sum of money in the village's most capable people through collective governance. All members share the income as angel investors.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Myriad Social is a social network that allows users to have their own platform without being controlled by a central authority. It is decentralized and censorship-resistant.

    Our app is developed using the Myriad blockchain, specifically as an appchain that runs on the Octopus Network. This provides several benefits. Firstly, it's censorship-resistant since there's no central control point. Secondly, it offers sovereign control as all data is kept in user-hosted instances with the freedom to host.

    The product proposition of myriad is as follows:

    • Myriad, a Federated Free Speech platform, empowers users to host their own social network and be a part of the Federation. By self-hosting, users can create their own server and invite others to join, enabling anyone to establish their own social network without depending on a central service.

    • Myriad Social offers a decentralized alternative to current social media platforms. With their crowdsourced method of importing social media posts, users can follow individuals on centralized networks without needing an account on those networks. This allows for greater accessibility and diversity of content.

    • With Myriad's Crypto Value Layer, users can gather posts from various social networks such as Twitter or Reddit and transfer them onto the blockchain. This transforms each post into a tipping wallet, enabling regular social media users to receive cryptocurrency for their content.

    • Myriad Social is a social media platform that is run by both $MYRIA token holders and users, making it self-governing. Unlike traditional platforms, it operates in a decentralized manner, which means that the governance system is more democratic and fair, without being controlled centrally.

    • At Myriad Social, our goal is to support the wider community by offering a range of pallets, services, and seamless integration options for federated social technologies. We strive to enhance the overall ecosystem and provide users with a more comprehensive experience.

    At Myriad, we prioritize interoperability. Our blockchain is powered by Substrate, a framework developed by Parity Technologies for Polkadot. This choice allows for greater flexibility, as our blockchain can easily connect with other popular blockchains like Octopus, Kusama, and Polkadot.

    In addition, Myriad has a federated architecture designed for modularity. This means that its components are extensible and can be treated like building blocks that can be assembled in any desired way.

    Our ultimate objective at Myriad Social is to become the primary decentralized social media platform of the future. After launching in early 2022, we have completed the first and second phases of our product's development, and it is now available on Octopus Network as an appchain. The Octopus project offers great flexibility as appchains can be deployed into a different ecosystem or live as their own blockchain. Additionally, Octopus Network supports protocols that "graduate" from its network. As the second appchain to go live on Octopus Network's ecosystem, Myriad has decided to level up and get embedded into the Kusama ecosystem to reach a wider audience.

    As a parachain that lives in Kusama/Polkadot/Web3 Ecosystem, Myriad provides:

    • A new decentralized social network with self-governance capability
    • A complete documentation on how to upgrade an existing Octopus appchain or similar substrate-based chains to any Polkadot Ecosystem
    • Multi wallet login using various providers

    Project Detailsโ€‹

    Architectureโ€‹

    The following is the architecture that has been deployed on Octopus Network as an appchain and will be deployed fully to Kusama as a parachain.

    • Kubernetes (GKE Cluster)
    • NodeJS
    • MongoDB
    • Redis
    • Bastion VM
    Componentsโ€‹

    Myriadโ€™s decentralization is organized into two layers โ€” the Myriad blockchain and the Myriad federation. While each of these two layers is a network of cooperating computers that collectively constitute the Myriad platform, each individual layer provides something to the platform that the other cannot.

    Myriadโ€™s blockchain layer (composed of Myriad Nodes) is developed with the open-source Substrate blockchain platform and secures data that must be held strictly in global consensus, such as ownership, asset transfer, and global reputation. This includes things like Myria token balances, Userโ€™s global reputation scores, and NFT ownership.

    Myriadโ€™s federation layer (composed of Myriad Servers) allows for both scalability and data sovereignty which would not be possible in a pure-blockchain architecture. The federation servers store things like communities, posts, and experiences. This type of data is distinct from the hard-consensus data stored in the blockchain in a few significant ways โ€” It can be high-volume, curated per server, and itโ€™s not used in hard-consensus decisions (such as ownership transfer validation.)

    Itโ€™s important to note that the same physical computer can be both a Myriad Node and a Myriad Server (although it need not be both.) These two protocols work together to provide the features of the Myriad platform as a whole. As a consequence of this dual-network architecture, the following things are made possible:

    • Myriad Server Operators maintain complete data sovereignty โ€” The network does not force Server Operators to host content they disagree with. This is not possible, for example, in a pure-blockchain architecture where a node operator only has the binary choice to either host ALL data, or not run a node at all.
    • Myriad Servers can scale to millions of Users by leveraging traditional horizontal scaling techniques (which is impossible with conventional blockchains by virtue of the scaling problem) while remaining fully decentralized and censorship-resistant by virtue of any personโ€™s ability to operate a server that maintains their own communityโ€™s data.
    • The social media experience can be seamlessly augmented by the ability to send and receive tokens, convert any post into an NFT (*future roadmap), or even automate the democratic governance of communities โ€” all with the security properties of hard-consensus blockchains (such as ledger immutability and the unforgeability of digital signatures.)

    Ecosystem Fitโ€‹

    Myriad solves the problem where social media has become too controlled by big corporations. By providing a decentralized social media, Myriad allows users on Polkadot/Substrate/Kusama ecosystem to interact and host their own node instances.

    • The target audience of this project is the general audience who are looking for an uncensorable and free social media with web3 capabilities
    • The project allows builders on Substrate ecosystem to extend and build on top of the Myriad API
    • Similar project: Subsocial. Key difference: Myriad Social is combining decentralization and federation, allowing the off-chain data of the social media to be fully owned by the community.

    Future Plansโ€‹

    Immediate Useโ€‹

    We will immediately use the functionality for a number of DAOs, communities, and businesses that we work with and participate in. This is a critical feature that these teams desire before they are ready to migrate to the Polkadot ecosystem.

    Greater Contextโ€‹

    In the greater context, we are working towards a Substrate standalone chain and/or parachain/parathread to be used by small and medium-sized businesses.

    Over the last several years, we have established a leading presence in this area of blockchain. For example, last year, we were the first organization to ever tokenize real estate directly on chain in a manner where the token represents FINAL and INSTANT settlement of ownership. This was only possible in Wyoming after the DAO LLC legislation became effective in July 2021. In other words, a token holder can show their asset(s) to the Wyoming Supreme Court and they will protect their property rights. The LLC veil also sheilds DAO members from any personal liability. We attend the legislative sessions in person of the Select Committee for Blockchain and Financial Innovation in Wyoming.

    For a detailed legal explanation and step-by-step review of how we achieved this, please see our Digitalness Primer article and how Kitchen Lands DAO LLC Buys 35 Acres in Wyoming. In fact, the Chairperson of the Committee, Senator Chris Rothfuss, tweeted in support of our efforts and legal interpretation.

    This project has received much positive feedback and press, including this article from The Information.

    Along these lines, we have and are building several other critical modules for small businesses, including:

    Q&Aโ€‹

    Do you know of any similar projects on other blockchains?โ€‹

    There are tons and tons of examples of wrapped Bitcoin of course, with various forms of trust, custody, and/or light clients. As referenced above, there is also interlay/interbtc in the Dotsama ecosystem which seems to be trustless and supports insurance for lost Bitcoin.

    In a few DAOs we built and participate in on Telos, there's an onchain badge for treasurers as they are elected/assigned, which helps, but certainly falls well short of delivering what NBV does.

    Besides that, I have not come across any tools or products that offer this capability, and certainly not with the strength of user experience that non-technical users expect and we intend to build.

    Comparison to Remark palletโ€‹

    What for example is the advantage of your solution compared to having a bitcoin multisig wallet which is controlled by a DAO and signing a remark on substrate that says this multisig account is controlled by the DAO? I guess you could do the same on bitcoin using OP_RETURN.

    This would be possible. At a high level, any state trie and state transition function can be summarized to a hash to sign in a remark. As seen with the RMRK NFT project ๐Ÿ‘, a lot of functionality can be driven through that capability. The benefit of using remark is that it is compatible with the relay chains.

    The trade-offs, IMHO, are mostly around usability, composability, and designing idiomatically, which I find incredibly useful for re-usability by other developers (particularly in initial releases). As an example, the Identity pallet developer chose to store fields, including the registrars' judgments ๐Ÿง‘โ€โš–๏ธ , within the pallet rather than hashing them into a remark field. I tend to think of these as "first class" attributes because the architect decided they were worth the space and mind-share of being stored directly on chain. In a similar pattern, I think the xpubs ๐Ÿ”‘ are important enough to persist this way also.

    In the future, I expect there to be a quite complex many:many relationship between users, DAOs, and vaults. For example, within the Hypha DAO, there are team "circles" or quests (projects) that are allocated a budget to a vault. There may be many circles/quests per DAO. There may also be many DAOs and circles/quests for each user, and they will likely desire different xpubs in their profiles for these scenarios.

    We can use the remark pallet, and it would be valuable 'back-end' for NBV that works on the relay chains. I think there are likely privacy preserving benefits to this as well. But the functionality and logic of generating the output descriptors dynamically along with receiving addresses, the user experience, vault handling, managing the user flow, etc, still needs to be developed.

    My suggestion would be that we implement the most vanilla, idiomatic way first, and then add compatibility to relay chain/remark as a future step. OP_RETURN compatibility is interesting too. A caution with that is, in my experience, the more complex/obfuscated the persisted state, the harder it is (more tooling/logic) for more casual users to verify and adopt. But there is absolutely value in pursuing these. Let me know what you think, and we would be happy to pivot or add this to the proposal.

    Overviewโ€‹

    Please provide the following:

    • If the name of your project is not descriptive, a tag line (one sentence summary).

    Implementation of my hash function in Sage in the general case and in Rust specifically for the curve BLS12-381.

    • A brief description of your project.

    Recently, my article https://link.springer.com/article/10.1007/s10623-022-01012-8 was published in the quite prestigious cryptographic journal "Designs, Codes and Cryptography". This article provides a new hash function (indifferentiable from a random oracle) to the subgroup G1 of many elliptic curves of j-invariant 0, including most pairing-friendly curves of the family BLS12 (Barreto-Lynn-Scott) of embedding degree 12. Such curves and hash functions are actively used in blockchains, namely in the BLS (Boneh-Lynn-Shacham) aggregate signature. According to the web page https://wiki.polkadot.network/docs/learn-keys, the BLS signature will be in particular used in Polkadot.

    My hash function is much faster than previous state-of-the-art ones, including the Wahby-Boneh indirect map to the curve BLS12-381. This curve is a de facto standard in today's real-world pairing-based cryptography. The indifferentiable Wahby-Boneh hash function requires to extract two square roots (i.e., to compute two exponentiations) in the basic field Fp. In comparison, the new hash function extracts only one cubic root, which can be also expressed via one exponentiation in Fp. And according to Section 1.1 of my other article https://eprint.iacr.org/2021/1082 the exponentiations for square and cubic roots in Fp have short addition chains of about the same length.

    I have already checked the correctness of my results in the computer algebra system Magma. The new project is dedicated to an implementation of the new hash function to BLS12-381 in Rust. This project is a follow-up of the previous one concerning a proof-of-concept implementation in Sage (see #825). I wrote such an implementation, but I didn't finish the project, because my code does not meet high standards of Web3 Foundation. However, I found a professional developer in Rust who is ready to provide a Rust implementation (based on my Sage one), including tests. Consequently, besides my initial $10,000 reward (level 1), an additional reward for my colleague's work is required.

    • An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama.

    According to the web page https://wiki.polkadot.network/docs/learn-keys, the BLS signature will be in particular used in Polkadot.

    • An indication of why your team is interested in creating this project.

    Because I want to demonstrate to the blockchain society that my research has an immediate practical value.

    • PoC/MVP or other relevant prior work or research on the topic

    My article https://link.springer.com/article/10.1007/s10623-022-01012-8 under the name "Indifferentiable hashing to ordinary elliptic Fq-curves of j=0 with the cost of one exponentiation in Fq".

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

    Hashing to elliptic curves in the BLS (Boneh-Lynn-Shacham) aggregate signature.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    Developers who will use the new hash function in their implementations of cryptographic protocols.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?
      • If so, how is your project different?
      • If not, are there similar projects in related ecosystems?

    I don't know, because my project is quite extraordinary, in my opinion. Maybe, similar projects (based on recent results of mathematical cryptography) periodically arise in the Ethereum Foundation grants program.

    Team's experienceโ€‹

    There is the regularly updated CFRG draft on hashing to elliptic curves: https://datatracker.ietf.org/doc/draft-irtf-cfrg-hash-to-curve/. As for me, at the beginning of the last year, as said in https://blog.ethereum.org/2021/11/04/esp-allocation-update-q2-2021/, I won an Ethereum Foundation grant to derive a fast hash function to the subgroup G2 of the pairing-friendly curve BLS12-381. As an outcome of this grant, in Section 1.2 of https://eprint.iacr.org/2021/1082 I prove that for hashing to G2 the Wahby-Boneh map applied only once (not twice) is sufficient to act as a random oracle. Thus we get rid of one exponentiation in the quadratic extension Fp2 or, equivalently, of two exponentiations in the prime field Fp. Besides, I constructed a series of hash functions to other elliptic curves in the articles https://eprint.iacr.org/2021/1034 (accepted in SIAM Journal on Applied Algebra and Geometry), https://link.springer.com/article/10.1007/s12095-021-00478-y (published in Cryptography and Communications), https://eprint.iacr.org/2021/1604 (submitted to Journal of Mathematical Cryptology).

    1.ImplementationSage (non-constant-time) implementation of the hash function described below.

    To be definite, let me use the notation of my article https://link.springer.com/article/10.1007/s10623-022-01012-8. The new hash function consists of three components: a classical one \eta: {0,1}^ -> Fp^2, a rational map \varphi: Fp^2 -> T(Fp), and an additional map h^\prime: T(Fp) -> E(Fp), where E is a given elliptic Fp-curve of j-invariant 0 and T is a suplementary algebraic threefold. A construction of \eta is represented in Section 5 of the draft https://datatracker.ietf.org/doc/draft-irtf-cfrg-hash-to-curve/. This is the composition of a hash function {0,1}^ -> {0,1}^n for some n \in N and the subsequent restriction modulo p, hence we can use a standard hash function from one of cryptographic libraries. It remains to implement \varphi and h^\prime just as described in my article.

    It is also worth noting that the new hash function is relevant for any ordinary (i.e., non-supersingular) elliptic Fq-curve y^2 = x^3 + b (of j-invariant 0) such that the square root of b lies in Fq. Here Fq is an arbitrary finite field (of characteristic p > 3) for which 3 divides q-1, but 27 does not. Therefore, our Sage implementation is in fact relevant for all such curves and fields. The BLS12-381 curve corresponds to the case when q = 10 (mod 27) and b is not a cubic residue in Fq.

    1.ImplementationRust non-constant-time implementation of the new hash function for BLS12-381. It is suggested to use the library arkworks (https://github.com/arkworks-rs/curves) as a base. In particular, to perform the (unique) exponentiation in Fp an addition chain of quite small length has already been derived in https://github.com/dishport/Some-remarks-on-how-to-hash-faster-onto-elliptic-curves (cf. Section 1.1 of https://eprint.iacr.org/2021/1082).

    Future Plansโ€‹

    The new hash function appears to be optimal, because it performs only one exponentiation in the basic field Fq. In other words, since it is highly unlikely that there is a hash function to an elliptic curve without exponentiations at all (even if it is supersingular), the result of my article seems to be unimprovable. Thus I hope that the implementation of my hash function will be interesting not only to you, but also to all blockchain projects that involve the BLS signature.

    The goal is to have a deployed, playable, and marketable test version on a public network at the end of Milestone 4. The combination of space exploration, leaving a permanent mark on an inifinite universe, combined with a tactical combat element, all delivered in a modern 3d web (hybrid) app, will provide a broader "reason" to enjoy the game, and the ranked combat (leaderboards + staking own ingame money on fights) will provide a competitive element to compliment.

    In time (after M4), the Universe will become more diverse; producing different minerals which will be used to craft Modules of certain parameters. The minerals/production system should offer the player an option creation of an "industry" used to produce Modules, and the mineral types should be randomly generated when discovering Systems, making control of some Systems more attractive than others and giving more reason to territory control.

    Once released to test users, additional features will be driven by test user feedback, at which stage we will also trigger development on onboarding features (in game tutorials, starting resources, but also gas (weight => transaction cost) sponsoring model to remove the requirement of owning tokens for new players (to pay registration contract's gas fees, for example).

    NFT Collectibles Wallet

    • Payment Address (DAI): 0x16D7A415040D52F2427C2b921dfC31829C0d17fc
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    The NFT Collectibles Wallet is a multi-chain non-custodial mobile wallet which will allow users to claim, store and manage an unlimited number of NFTs from any Substrate based blockchain. This project will consist of 2 major parts: the mobile wallet for users and the javascript sdk for front-end developers to create NFT management UI.

    **Users:** By scanning QR codes, users will be able to claim NFTs into their wallet. These NFTs can be consumed (burned), listed for sale or sent to others. Users will also have the ability to mint NFTs from within the mobile app. The mobile app will be downloadable from Apple's App Store and Google's Play Store.**Front-end developers:** By using the `nft-wallet-javascript-sdk`, javascript developers can create a UI for creating new NFTs. This javascript sdk will be able to connect to any substrate node via Polkadot.js.

    Overviewโ€‹

    The reason we are creating the NFT Collectibles Wallet is to allow users of GamePower Network (https://www.gamepower.network) to claim NFTs from games published on the platform. We could have made the wallet closed sourced such as other projects (Enjin Wallet), but we decided since we are the new kids on the block, it is better for us to contribute to the Substrate/Polkadot/Kusama community. That is what excites us so much about this project.

    Our team is very passionate about gaming and NFTs. We believe the use case for NFTs in gaming is one of the most valuable in crypto right now. The problem we see with NFTs is that explaining NFTs to the general consumer and giving them a streamlined and friendly place to use those NFTs is lacking. We want to solve this with the NFT Collectibles Wallet.

    Project Detailsโ€‹

    • Mobile Wallet Details:

    The mobile wallet will be built using React Native. We feel this will allow us to use a coding language (javascript) we've used for years and build performant mobile applications. Using React Native also allows us to code once and deploy on multiple mobile platforms.

    Mobile Stack:

    • React Native
    • Polkadot.js
    • react-qr-scanner

    A mockup of our mobile wallet UI. This mockup outlines the wallet creation, QR scanning and collectibles viewer. img

    • Substrate Pallet Details:

    The nft-wallet-pallet will use ORML (open runtime modules library: https://github.com/open-web3-stack/open-runtime-module-library) which will provide us with some underlying NFT code. The pallet will also talk to the balances pallet to handle any minting and consuming which is needed since each NFT is minted with a type of currency native to the blockchain it is on.

    Substrate Stack:

    • Substrate
    • ORML

    These methods will serve as an interface for the NFT Wallet to communicate with any substrate runtime. nft-wallet-pallet expects ORML's nft pallet to be a part of the runtime since it will be used to handle all NFT related functions.

    We will expose a SEND and BURN callback so that the runtime can do any domain specific logic when sending or burning an NFT.

    fn send(origin, asset_id: u64, recipient: AccountId) -> Result;
    // burn the NFT with a short reason used by dapps
    fn burn(origin, asset_id: u64, reason: Vec<u8>) -> Result;
    // list an NFT for sale
    fn list(origin, asset_id: u64, price: T::Balance) -> Result;
    // buy a listed NFT
    fn buy(origin, asset_id: u64, list_price: T::Balance) -> Result;
    // add an emote to the NFT (for social)
    fn emote(origin, asset_id: u64, emote: Vec<u8>) -> Result;
    // allows a user to claim a minted NFT
    fn claim(origin, asset_id: u64) -> Result;
    • Javascript SDK Details:

    The front-end UI will be built using React + Polkadot.js. This will be a straight-forward and clean UI to allow the creation and management of NFTs. This UI is not a front-end for consumers but for developers to create NFTs. The underlying SDK for the front-end can be used to create any type of custom NFT management UI.

    Web Stack:

    • React
    • Polkadot.js

    Ecosystem Fitโ€‹

    The NFT Collectibles Wallet provides the ecosystem with a streamlined and standard way to create, manage and exchange NFTs. By allowing the wallet to connect to any substrate based chain, users can freely move around the ecosystem without downloading multiple wallets for each chain, while still having a wallet that focuses specifically on collectibles.

    The NFT Wallet uses the RMRK NFT standard (https://rmrk.app/#standards). However the NFT Wallet project can potentially support other standards such as the new Enjin initiative on the Polkadot ecosystem.

    Our target audience is 3-fold: The everyday consumer that wants to manage their NFTs, The Substrate blockchain developer that wants to connect to the NFT Collectibles Wallet to offer NFTs on their blockchain and finally Dapp developers who want to offer their users NFTs through QR codes.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    The most similar project to the NFT Collectibles Wallet is the Enjin Wallet. However, the Enjin wallet is closed sourced and multiple blockchains cannot directly integrate into it in a decentralized way. This project solves that issue by being open sourced and allowing anyone that is a part of the ecosystem to contribute and enhance the project. Also by removing the wallet's centralization, any Substrate blockchain can make use of it.

    Currently, work for the NFT Collectibles Wallet has not started, but the team has started initial work on GamePower Network (https://www.gamepower.network) which will be the first project to implement the NFT Collectibles Wallet. The wallet was actually conceived because of the GamePower project. The need for the NFT wallet was very important and we decided to open the project up to anyone in the ecosystem that has the same need.

    Future Plansโ€‹

    This NFT Collectibles Wallet will be used as part of the GamePower Network. GamePower will operate on the Kusama and Polkadot platform and will be the first application of it's kind that delivers decentralized game publishing. GamePower will use the NFT Collectibles Wallet to allow users of GamePower to store NFTs purchased or earned through GamePower either in a game or through the GamePower NFT marketplace.

    However, Development of the NFT Collectibles Wallet won't end after all milestones are met. We plan to add features such as Minting NFTs from within the application by users, A way for the app to automatically discover blockchains using NFTs on its own (maybe through some type of registry). There are endless possibilities where this wallet can go and we are very excited to get started on it!

    Additional Information โž•โ€‹

    Currently we have no funding for this project or GamePower Network, we feel getting the NFT Collectibles Wallet off the ground will kick-start our GamePower Network development in a big way. We are excited to be part of the Substrate and Polkadot community and we will continue to contribute as much as we can. Thank you for your time and thank you for considering us for the Web3 Open Grant.

    Uniscan NFT Explorer

    • Team Name: Uniscan
    • Payment Address: 0x480821a0700b0d5fBC722a5339ED2d49979Eaa42 (DAI)

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Uniscan NFT Explorer wants to be the best place to analyze, track and discover NFTs.

    Uniscan NFT Explorer hopes to create a unified NFT dedicated explorer for the Polkadot / Kusama ecology. It can be used to discover and view the NFTs in important parachains in the Polkadot / Kusama ecology.

    The vision of this explorer is to become a better platform for discovering and analyzing NFTs. In the future, we can provide more tools for discovering and analyzing NFTs, such as combining on-chain data and off-chain data to provide users with some statistical views.

    We hope that through this grant, we can better understand NFT and lay a foundation for the realization of this vision. This grant is the first step of this vision, that is to achieve a basic browser structure and functions, and only focus on evm. Through this grant, we hope to

    1. establish a reliable technology architecture.
    2. choose the best technology stacks.
    3. better understand nft, and improve the data model,
    4. implement a better style suitable for NFT display.

    Project Detailsโ€‹

    Architectureโ€‹

    This is a standard web program, the main structure includes three layers.

    The first layer is the Web server, which is responsible for rendering browser pages, showing NFTs to users, and providing some interactive functions.

    The second layer is the database layer. A data model is used in the database to store all NFTs data, and the Web server will query the data from the database.

    The third layer is the data query layer connected to blockchains. In this layer, there will be a number of long-running workers. These workers will monitor or poll blockchains to discover NFTs, and then combine these NFTs with their related data into the database, and the push service will also be notified to push the latest data to the browser. In addition to obtaining data through blockchains, this layer may also grab data from some centralized or decentralized services, such as grabbing transaction data from Markets, etc. This part is not in the scope of this grant.

    This grant application only focuses on the NFTs on the evm-compatible virtual machine in the Polkadot ecosystem, and only monitors and saves the ERC721 and ERC1155 compatible NFTs. And only considers connecting two substrate based blockchains.

    In the future, we will apply for other grants based on the completion of this grant, including more chains, support for wasm based NFTs, and support for more types of NFTs, such as RMRK.

    Ecosystem Fitโ€‹

    We believe that there will be various NFTs in the Polkadot / Kusama ecosystem in the future, so a unified nft explorer must be very important. Now many parachains will support the creation of NFTs. Users interested in NFTs will want to have a unified entry to view these NFTs.

    We found that there is no unified and easy-to-use NFT browser in the current Polkadot ecosystem.

    Potential users of the NFT browser include NFT collectors, NFT creators, NFT speculators and other applications.

    Kodadot gallery is a rmrk nfts gallery.

    The difference between us is that the purpose and direction. Kodadot gallery is a part of the RMRK. Uniscan's current goal is to support NFTs of evm pallet. The Uniscan's final goal is to build an all-in-one NFT explorer for Polkadot & Kusama ecosystem with some data statistics for users to easily discover NFTs.

    Why evm?โ€‹

    1. Evm is the most widely adopted virtual machine platform in the Polkadot/Kusama ecosystem, so there will be a lot of NFTs to be issued based on evm pallet.
    2. There is not an NFT explorer support evm in the Polkadot/Kusama ecosystem.
    3. It is difficult for the NFT explorers of the Ethereum ecosystem to cover the chains in the Polkadot ecosystem. And they are not permissionless.

    Overviewโ€‹

    Introductionโ€‹

    Over billions of dollars of digital collectibles (NFTs) have been minted and traded. The people minting these tokens need to know who's interacting, buying, selling, and how they should best create them. They also need to know what different variations of digital collectibles have gamification or point elements that are attached to these assets and how users are receptive to this. With this information at hand, they can get faster and more effective feedback so they can make artful or functional digital collectibles that drive the right behaviors for that model. In the traditional space, companies have access to tools such as Segment and Google Analytics, that have become commonplace due to opportunity cost and user retention. We plan on bringing that functionality into the blockchain space.

    Project Detailsโ€‹

    The NFT Product Analytics Suite will aggregate various data points both off and on chain to provide NFT minters the metrics they need to use to decide how to best serve their target audience. This will include tracking the transfers of the user's minted NFTs, when and how much they are being sold for, and price trends. We will also aggregate the meta data associated with a given NFT to see the effectiveness of various gamification methods. With this data being tracked, you will be able to compare your NFTs to other leading projects and artists to see what the difference is and how to better target end users.

    • Data Gathering
      • Chain Indexer (find the indexer they've funded)
      • Marketplaces
    • Insights
      • Chain of custody
      • Price Trends
      • Revenue Tracking
      • Insights about projects

    Ecosystem Fitโ€‹

    Where and how does your project fit into the ecosystem? / What need(s) does your project meet?

    • With the largely growing adoption of NFTs, whether you are a game company or an NFT artist, a major pain point is the lack of easy access to metrics that are standard in other non-blockchain-based ecosystems. Those metrics have proved detrimental in how people decide to best present their offering to their target audience, but have remained largely out of reach for a large portion of the early adopters in the NFT space either due to time or technical experience. NFT artists and content creators will be able to track their progress, spot trends, and better tell what their customers want without getting lost in technical documentation or spending time manually collecting data. Companies won't have to devote time or development resources to come up with an in-house monitoring solution to track revenue, user adoption, and easily compare new ideas.

    Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    • In-house
    • Blockchain companies and NFT-based Solutions
    • NFT artists and content creators

    Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    • There are projects that index the chain, but none that are specifically tracking metrics that are related to NFTs both on and off chain

    Ecosystem Fitโ€‹

    Ocelloids SDK provides several advantages to the ecosystem:

    1. Ocelloids is the first open-source SDK to build complex monitoring applications. Its design provides a smooth experience for developers by abstracting away the underlying complexity of the monitoring logic.
    2. It provides reusable components that take care of common patterns for reactive sourcing and filtering, including call batching and multi-signature calls, which can be complex and time-consuming to implement manually.
    3. Ocelloids' domain logic for ink! smart contract monitoring will be a valuable addition to the Substrate ecosystem. Smart contract monitoring is an essential infrastructural piece for Dapp developers as seen by the popularity of services such as OpenZeppelin Defender and Forta detection bots. There is currently a lack of similar sophisticated services for ink! contracts and Ocelloids SDK will provide the necessary base to build powerful ink! monitoring applications.

    Our long-term vision is to offer an end-to-end solution accessible as a web application to allow end-users to configure monitoring agents and subscribe to on-chain activities of interest. The web user interface exposes the domain logic components for monitoring use cases. For notifications, we will integrate with a notification centre solution, like Novu.

    We will start with contracts monitoring for parachains and solo chains that integrate pallet-contracts. Later, we plan to expand the offering to other pallets and networks, including custom pallets of parachains and solo chains. The key differentiator with existing solutions is the bundling of vertical logic per pallet with complex monitoring patterns.

    Additionally, we will explore integrating the core technology into Forta bots.

    Ocelloids XCM Transfer Monitoring Service

    • Team Name: SO/DA zone
    • Payment Address: Fiat 04.05.2023, 16:37
    • Level: 2

    Project Overviewโ€‹

    This grant proposal is a follow-up to the Ocelloids Monitoring SDK, previously delivered and available here: https://github.com/w3f/Grant-Milestone-Delivery/pull/934

    The objective of this grant is to develop an open-source monitoring service using the Ocelloids SDK. This service will monitor XCM transfers across selected parachains. The primary purpose is to offer service providers integrating with a single chain (Asset Hub as starting point) and monitoring effects on other chains that are connected via HRMP and that use XCM as their message format. The service will support connecting to the configured networks through light clients in order to reduce infrastructure overhead for service providers. Users will have access to a self-hosted HTTP API to subscribe to XCM transfers and manage their subscriptions. A public Docker image will be published to facilitate service deployment.

    Project Detailsโ€‹

    The service will support bidirectional XCM transfers, namely asset teleports and reserve-based transfers, between selected parachains.

    The flow of the monitoring will work as follows:

    1. The service will monitor on the origin chain for the event xcmpqueue.xcmpMessageSent associated to the extrinsic sent by accounts of interest. The service will extract the XCM message hash from this event.
    2. The service will query the storage in parachainSystem.hrmpOutboundMessages at the block of the event to get all outbound messages and filter for recipient chain IDs that are supported. Subsequently it will decode the message data to get the set of XCM instructions to filter for combinations of instructions related to asset teleports or reserve-based transfers (i.e. ReserveAssetDeposited, ReceiveTeleportedAsset, WithdrawAsset, and DepositAsset). Then, it will get the blake2-256 hash of the message data to match it with the message hash obtained in Step 1. The service will store a persistent task to be matched in subsequent steps.
    3. At the destination chain, the service will monitor for the events xcmpqueue.success and xcmpqueue.fail. It will match the message hash extracted from these events with the message hash of the origin.
    4. It will send a notification to the configured webhook to inform of the status of the XCM transfer along with contextual information. See section Notifications for details.

    Before using the service, users will need to configure the supported networks and connection providers. An example configuration can be found in the section Service Configuration. We will support connections to the network using both RPC clients and light clients. Further details on supported Substrate clients can be found in the Supported Substrate Clients section.

    The service will expose an HTTP API for users to add subscriptions, specifying the channels they want to monitor and the accounts involved. Users can create multiple subscriptions and modify or delete them as needed. Users can also set up webhook endpoints to receive notifications related to their transfers. Detailed information about the API will be provided in the Subscriptions API section.

    To keep the project manageable, the current scope includes support for Asset Hub, Astar and Acala. In the future, we plan to expand support to include more chains.

    Notificationsโ€‹

    As previously mentioned, the monitoring service will accept webhook endpoints for delivering notifications. Initially, notifications will be provided for XCM message reception.

    The following types of notifications correspond to different scenarios:

    XCM Execution Success

    The XCM message sent from the origin chain was received and executed successfully. In this case, we will send an "XCM Transfer Success" notification, including contextual data such as the XCM message hash, block numbers of the XCM message on the origin and destination chains, sender account, beneficiary account, transferred asset and amount.

    XCM Execution Fail

    The XCM message was received at the destination chain but failed to execute correctly. In this case, an "XCM Transfer Fail" notification will be sent, including the XCM error returned in the event and additional contextual data.

    Service Configurationโ€‹

    The service will load a configuration file at startup, similar to the example provided below:

    {
      "networks": [
        {
          "name": "assethub",
          "id": 1000,
          "relay": "polkadot",
          "provider": {
            "type": "ws",
            "url": "wss://asethub-rpc"
          }
        },
        {
          "name": "parallel",
          "id": 2012,
          "relay": "polkadot",
          "provider": {
            "type": "smoldot"
          }
        }
      ]
    }

    Other common service options, such as the listening port for the Subscriptions API, will be configurable using environment variables.

    Subscriptions APIโ€‹

    API Methodsโ€‹

    POST /api/subscriptions/{id}

    Creates a new subscription document. To avoid the need for the client to store a server generated identifier, we will require the client to provide a unique subscription identifier. This will also allow the client to use meaningful identifiers e.g. 1000-2004-cohort1.

    Example request body:

    {
      "subject": "xcm-hrmp-transfers",
      "args":{ 
        "origin": {
          "network": "assethub",
          "senders": [
            {
              "accountId": "5GEWco3EGfM27Z9cAmVnzFnZ6Y7vkqNVvWM4NgQZj4n84Wh6",
              "type": "AccountId32"
            }
          ]
        },
        "destination": {
          "network": "moonbeam"
        },
      },
      "notification": {
        "type": "webhook",
        "url": "https://my-callback",
        "maxRetries": 50
      }
    }

    PATCH /api/subscriptions/{id}

    Accepts a JSON Patch operations array according to RFC6902

    Example:

    [
      {
        "op": "add",
        "path": "/args/origin/senders/1",
        "value": {
          "accountId": "5HWSEZr3DQXaN4Tk2Y9pYyAPKWeu28P94qeWWgUZ4k2mrbGB",
          "type": "AccountId32"
        }
      }
    ]

    The resulting patched document will be validated against the subscription document schema.

    DELETE /api/subscriptions/{id}

    Removes a subscription by ID.

    GET /api/subscriptions

    Returns the list of subscriptions.

    GET /api/subscriptions/{id}

    Returns the subscription document under the specified ID.

    PUT /api/subscription/{id}

    Replaces an existing subscription document by ID.

    Supported Substrate Clientsโ€‹

    We will support WebSocket RPC endpoints and light clients. However, please note that light client support may be limited due to its experimental nature.

    During preliminary testing, we identified some limitations:

    1. Using the Smoldot through Subtrate-Connect only support bootnodes configured with secure WebSocket connection. In our exploration, we've seen that only Astar and Acala have bootnodes with secure WebSocket connections. However, it is easy to overcome this limitation since Smoldot supports all the connection types. Reference: Github issue

    2. Some runtimes, such as Moonbeam, currently cannot be compiled by the light client. Reference: Github issue

    We will prioritize chains that are light client ready.

    Storageโ€‹

    We will provide persistent storage for operational data, including subscription configurations, processed block number and hashes, XCM messages and notifications. We will use Level as the database abstraction backed by LevelDB.

    Catch-up Mechanismโ€‹

    We will implement a mechanism to process missed blocks in case the monitoring service experiences downtime. For each processed block, its hash and block height will be saved in the database. When the service restarts, it will begin following the current finalized blocks. If the parent hash of the finalized block does not match the last-known hash stored in the database, the service will start processing the missing parent hash blocks until all missing ones are processed.

    Management Toolsโ€‹

    Since notifications and XCM message matching tasks are stored in the database and retried until success, we will provide a method to clear pending states. This is crucial to prevent indefinite retries of pending tasks. For example, if a webhook endpoint is changed while a notification is pending, it may never succeed.

    We will supply a script enabling administrators to inspect and remove XCM message matching and notification tasks from the database.

    Tech Stackโ€‹

    Ecosystem Fitโ€‹

    This project aligns well with the growing demand for robust tooling and infrastructure necessary to fulfill Asset Hub's vision of becoming the main place for asset management within the Polkadot ecosystem. To expand its user base, Asset Hub must provide a solution that abstracts away the technical intricacies of cross-chain transfers and enhances the user experience for managing assets across the expansive Polkadot ecosystem.

    The Integrations Team at Parity is already taking initial steps toward achieving this goal by working on the Assets Transfer API and the NoS launch script. These efforts target custodians, exchanges, and institutions, simplifying integration with Asset Hub and the construction of XCM messages. The importance of these tools, along with the overarching vision for Asset Hub, is comprehensively outlined in Iker's Polkadot forum post.

    The addition of the Ocelloids XCM monitoring service will enhance this toolkit, providing institutions with a straightforward method to track their cross-chain transfers. This corresponds to step 4 of the "Withdrawals User Journey Example" in Iker's post, as detailed here.

    With the inclusion of support for light clients in the service, institutions will experience a substantial reduction in infrastructure overhead since they will no longer need to run parachain nodes to monitor their transfers.

    Furthermore, the demand for a generalized monitoring solution with XCM support has been highlighted in discussions within the Polkadot community, as illustrated in this Polkadot forum post: Generalized multichain monitoring solution.

    Future Plansโ€‹

    For the XCM monitoring service, we have plans to expand its capabilities and reach which include:

    1. Support for More Networks: We plan to broaden the range of networks supported by the XCM monitoring service, enabling a more extensive and inclusive monitoring ecosystem.

    2. Support for More XCM Protocols: We will add support for XCMP when ready.

    3. Enhanced Notifications: Depending on user requirements and community feedback, we will extend our notification capabilities. This may involve providing notifications for asset transfers' initiation, such as when the block containing the XCM transfer is finalized on the origin chain. We are also considering notifications for when XCM messages sent through HRMP are processed on intermediate chains.

    Our long-term vision for Ocelloids extends beyond just monitoring XCM transfers. We aim to create a hassle-free, comprehensive monitoring portal for Substrate networks and smart contracts within the ecosystem. This portal will offer a set of advanced features, including:

    • Ready-to-use monitoring logic, i.e. monitoring programs, for the entire ecosystem. The XCM monitoring logic built through this grant could be one such monitoring program available.
    • Marketplace for monitoring programs where users can subscribe to the programs that correspond to their needs.
    • Advanced capabilities: anomaly and attack detection, machine learning, and forecasting.
    • Real-time actionable insights on network, contract performance, compliance, and security.
    • Multiple data centres for global, high-availability monitoring.
    • Seamless integration with existing systems like Prometheus and SIEM.

    In summary, our future plans encompass not only expanding the technical capabilities of the XCM monitoring service but also positioning as a central hub for monitoring and managing Substrate networks and smart contracts within the broader multi-chain ecosystem.

During this program teams are guided to build new user experiences using Momentum and Dotsama tech and test how the DRIVE token strengthens their usecase. In September 2023 we will launch our DRIVE mainnet as a parachain on Kusama.

    In the coming years we will keep investing in the Kusamaverse and momentum ecosystems, meaning:

    Momentum provides a novel social communications medium and provides the infrastructure for a new user experience where social, economic and cultural activities, both on-chain and off-chain are intertwined. In these early beginnings we are only scratching the surface of what is possible. But we are convinced we are at the start of an exciting journey and with Momentum we are in for the long run.

    The project will be split in 2 milestones that will be supported by a group of 2 developers, 1 UI/UX designer, 1 PO and 1 QA.

    Overviewโ€‹

    Milestone 1 โ€” Design and development of an Ink! smart contractโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can run our smart contract and send test transactions, which will show how the functionality works.
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    1.Liquidity pool management methodsWe will create methods for keeping and managing main liquidity pool, withdraw/top-up assets from/to main liquidity pool (service provider's pool)
    2.Coupon data storageWe will create a method for storing issued and sold coupons in the smart contract
    3.Coupon registrationWe will create a coupon registration method (for each registered coupon code an appropriate assets volume will be locked in the liquidity pool) and coupon code ZK-validation method (to prove to a coupon seller, that the coupon is registered and thereโ€™s enough liquidity locked for it without showing the private key)
    5.Coupon liquidationWe will create a coupon burn method upon itโ€™s redemption and corresponding transaction

    Milestone 2 โ€” Design and development of system management toolsโ€‹

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can run our smart contract and send test transactions, which will show how the functionality works.
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish an article that explains what was achieved, how to use the new Dapp and what benefits what are the benefits of using the system
    1.Centralized management back-endWe will develop service providerโ€™s CLI tools for coupon lifecycle management including: coupon generation algorithm implementation, coupon storage DB, coupon registration in a blockchain. Also it will include tools for liquidity pool management โ€“ assets top-up or withdrawal, get balance. Each coupon will consist of a public and a private key. Public keys will be delivered to the smart contract for operations. Private keys will be accessible only to buyers and will validate the transaction upon coupon redemption. Upon registration of a coupon in the smart contract the appropriate sum of tokens will be locked in the service providerโ€™s pool as a collateral for the coupon balance.
    2.Buyer's web interfaceWe will develop a web UI for coupons' redemption for users that already have an existing wallet with non-zero balance. Validation of the coupon will be made straight by the smart contract with gas taken from the userโ€™s wallet.

    Future Plansโ€‹

    Above defined deliverables are just a start position for future development of the product โ€“ a unified platform for users for easiest exchange of their fiat assets to crypto and with a personal wallet that can be used for payments in the ecosystem without excessive transactions and gas fees. Also, this is going to be a service for sellers and service providers to add straight fiat-to-crypto payments to their apps and smart contracts. The easiest way to perform a reliable yet confidential way of payments.

    Our future plans for the project:

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Open Node Framework is an end-to-end DevOps (SRE) solution to deploy a Substrate node network for staking and other purposes. It's designed to address high availability, scalability, and flexibility, using the modern technology stack.

    Project Detailsโ€‹

    While developing a Substrate based parachain, we found it challenging to operate and maintain different types of nodes. Validators and collators require high availability and key security. Bootnodes and RPC nodes require high performance and flexible scalability. So Open Node Framework has the following design purpose:

    • Parachain first: Focus on the requirement of parachains
    • Flexibility: Integrate with any Substrate based blockchain easily
    • Multipurpose: Run validators, collators, full nodes, bootstrap nodes, or RPC nodes
    • High Availability: Add redundancy to nodes (validators & collators) for higher security and robustness

    There are a few existing projects that can partially meet the above requirements. Among them, Polkadot Deployer is a k8s-based network deployment and monitoring tool. However, it's mainly designed for bootstraping and operating a full Polkadot, which may not meet the typical requirement of running a parachain. Therefore we think it's a good idea to iterate on it and make it parachain ready and address the features mentioned above.

    Tere are other interesting projects as well. Polkadot Secure Validator implements a validator setup for Polkadot and Kusama coming with a monitoring system Polkadot K8s Monitor. Gantree is a W3F Grant funded Substrate DevOps framework supporting customized Substrate node. However it lacks the support of node HA, and like the other two projects, doesn't support cross-datacenter deployment, and is not built on modern Kubernetes stack.

    Open Node Framework wants to feature:

    • Multi IT infrastructure
      • Native Kubernetes architecture
      • Cross-datacenter / cloud providers deployment with a central dashboard for daily management
      • Support multiple cloud providers with Terraform
      • Scale up to a large node network easily
    • High availability
      • Upgradable node binary
      • Blockchain database backup and recovery
      • DDoS mitigation
      • Collator and validator redundancy
    • Hardened security
      • Ops jump servers / VPN behind a firewall
      • RPC authentication
    • Monitoring
      • Dashboard and data visualization with Prometheus and Graphana
      • Grafana / Loki stack for metrics, logging, tracing
    • Flexible node integration
      • Replacible Docker images for node binaries

    Open Node Framework has its MVP implementaion availabe at our Github Repo. It implemented a basic infrastructure as shown in the above diagram. The components are deployed in a Kubernetes cluster with the binaries defined by Docker images. It supports both Terraform and Google GKE deployment, and it has been tested on Polkadot and Phala Network testnets.

    In this grant, we are going to expand Open Node Framework in aspects:

    1. Switch the code base to a fork of w3f/polkadot-deployer
    2. Enable parachain and 3rd party binary config
    3. Cross-datacenter deployment with a central place to manage and view the dashboard
    4. HA collator validator setup

    We are interested in the following areas but want to leave them for future work:

    1. Secure Enclave protected Key Management Service
    2. Integrate with indexing tools like SubQuery
    3. Comprehensive UI for the end users

    Open Node Framework doesn't aim to build everything from scratch. We prefer to utilize the existing open source tools and potentially contribute to them. We plan to work on a fork of Polkadot Deployer, and contribute it to the upstream if possible.

    The other building block candidates are:

    Ecosystem Fitโ€‹

    Open Node Framework provides the infrastructure to deploy any Substrate based parachain or standalone blockchain for multiple purposes, including running a bootstrap network, a validator cluster, a full node RPC service network, or a temporary simulation network for experiments, with all the essential infrastructure. It allows other Substrate blockchains to integrate with it easily.

    The project serves standalone the Substrate blockchain, parachain, and relay chain operators, offering them a flexible and user-friendly infrastructure framework with production best practice.

    We know each other from different places but we began working together at the Polkadot Blockchain Academy 2023 in Buenos Aires, Argentina. We formed a tight knit study group and helped each other to better navigate the Academy's teaching and to complete the myriad of coding assignments we needed to do in order to get certified as a Blockchain developer, which we all accomplished.

    Development Status ๐Ÿ“–โ€‹

    We started to work after we finished the Polkadot Blockchain Academy. We explored the Polkadot ecosystem and we found that there is a lot of potential for solving real world community problems with the technology currently available.

    To ensure a smooth and intuitive user experience, we've built a Wireframe that outlines the user flow of the project. This wireframe serves as a visual representation of how the user will interact with the project and provides a clear roadmap for the design and development process. By creating a wireframe at the early stages of development, we can identify any potential usability issues and make adjustments before investing significant time and resources into the design and development process. Ultimately, this will lead to a better user experience and a more successful project.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    We have decided to describe a full roadmap of an OpenBrush here, with estimates. However, the funding we request at this stage is for milestones 6-7.

    Previous workโ€‹

    Milestone 1 - Implement reusable basic contracts in ink!, similar to Openzeppelinโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will enhance inline documentation, and create a tutorial on how to import/customize contracts.
    0c.Testing GuideWe will add unit tests to cover all basic logic and integration tests with Redspot, to verify that all works via contract-pallet
    1a.Fungible token(Erc20)We will implement reusable Erc20 analog on ink!
    1b.Non Fungible token(Erc721)We will implement reusable Erc721 analog on ink!
    1b.Multi token(Erc1155)We will implement reusable Erc1155 analog on ink!
    2a.AccessControlWe will implement reusable AccessControl analog on ink!
    2b.OwnableWe will implement reusable Ownable analog on ink!

    Milestone 2 - Simplify usage of library. Add a new features which extend ink!. Provide macroses that will allow creation of your own base implementationโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will enhance inline documentation, update previous documentation based on simplifications, documentation for new features.
    0c.Testing GuideWe will test macros, update tests according to new features, simplifications.
    1.Remove boilerplate codeWe will provide a macro which will allow to remove boilerplate during usage of library(Library provides implementation on rust level in internal trait. User must reuse internal implementation with ink! messages. Our macro will simplify it). It will simplify the code structure and usage.
    2.Derive for storagesWe will provide a derive macro to generate implementation for storage's structs. It will simplify integration of fields inside of struct and implementation of storage's traits for that fields.
    3.Support default implementation in external traitsWe will add mnemonic support of default implementations inside of trait definition(traits defined via #[ink::trait_definition]). It is mnemonic, because under the hood we will generate internal trait with default implementation that will be used in external trait.
    4.Support of modifiersWe will add support of modifiers, like in Solidity. User will be able to mark some function to use modifiers and it will simplify the code.
    5.ReentrancyGuardWe will add implementation of ReentrancyGuard
    6.Implement additional useful contractWe will implement PaymentSplitter, TimelockController and etc.

    Milestone 3. Reduce the size of Erc20 contractโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a report of how much each optimization reduced the size.
    1.Reduce the size of Erc20 contractNow the most critical moment with ink! is the huge size of contracts. This issue described the problem very well. The parity team works in this direction, and we want to help with ink! side. The ink! team created issue 906, 916 and 910. We want to briefly(not full change, only minimal changes to reduce the size) implement them and provide a report(re-working data structure, reducing monomorphization, using dynamic dispatch in some cases). Based on this report, the ink! team can decide how better to implement them and which part is more critical. During the implementation, we will build examples with our version of ink! (also maybe we will modify some sub-crates). So the output of this work is a report and custom version of ink!. The code can be reused, or if ink! team agrees we can try to implement these issues by ourselves later as separate work.

    Milestone 4. Pre-release - Standardization of tokens contracts. Implement extensions for contracts. Documentationโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide inline documentation for macros, create a tutorial on how to use macros in your own project, with a detailed description of how it works inside.
    0c.Testing GuideWe will add more tests to cover all macros, update tests according to new changes.
    1.Create Proposal for Fungible tokenWe will create a proposal for standardization of Erc20 token in case of ink! and contract-pallet. Based on the final decision regarding the proposal update the implementation in library.
    2.Implement extensions for tokensWe will implement extensions for Erc20, Erc721 and Erc1155 tokens.
    3.Create Proposal for Non Fungible token and Multi tokenWe will create proposals for NFT and multi token, when proposal for FT token will be approved. Based on the decisions of these approves, we will update implementation in library.
    4.Use original ink! instead of our ownWe will use ink! 3.0-rc6 version(or a new one if it will be compatible) instead of our own version of ink!.
    5.Refactor the contracts to be compatible with PSPsWe will refactor the contracts according to the PSP.
    6.Refactor the structure of the OpenBrush to provide agnostic traitsWe will refactor the structure of the OpenBrush to provide traits for each implementation of the contract without restriction and implementation related information:
    - Traits will be defined in a separate module.
    - The default implementation of that trait for a contract will be provided via unstable feature #![feature(min_specialization)].
    - We will provide a new macro to generate a wrapper around a trait. That wrapper can be used for cross-contract calls. So the user is enough of the trait definition to do a cross contract call.

    Milestone 5. Release - Contribution to inkโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide inline documentation, example of usage of extensions.
    0c.Testing GuideWe will add tests for extensions and for a new changes from ink! side.
    1.Contribute to ink! with fixing of eventsWe will help to fix the issue with events.
    2.Re-work the storage of contractsWe want to resolve the issue.
    3.Refactor of implementation according changes in ink!After changes in ink! we will refactor the code of library.

    Current work - Scope of this Grantโ€‹

    Milestone 6. Upgradable contractsโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a documentation of how to write upgradable contracts
    1.Implement delegate_call in contract-palletThe ethereum has a delegatecall function that helps to achieve upgradable functionality in contracts. We will add the support of that function into the contract-pallet. With that function the OpenBurhs will provide the implementation fo Proxy and Diamond patterns.
    2.Implement set_code_hash in contract-palletThe usage of Proxy pattern adds overhead during each execution of the contract. It increase the cost of execution, and size of the proof of verification. Instead of delegate_call the contract-pallet can provide a separate function to change the source code fo the contract. It simplifies the flow and allow to easy upgrade the contract in the future.
    3.Import delegate_call in ink! and update Proxy exampleSupport of delegate_call on ink! level and providing a user-friendly abstraction. The ink! already provides an abstraction for cross-contract communication, we will extend it to support delegate_call.
    4.Implement Diamond Standard in OpenBrush with ink!We will provide the implementation of the Diamond standard in OprnBrush. Anyone can easily reuse the implementation or use traits to interact with contracts.
    5.Implement Diamond Standard on raw Rust without ink!Right now the ink! adds a lot of overhead and increases the size of the contract. Implementation of the Diamond standard with raw rust will show the overhead impact and will provide an additional example for WASM developers on how to write contracts without ink!.
    6.Create an upgradable analog of each contract in OpenBurshOpenBrush provides many implementations of different contracts. With upgradability, we also need to provide an upgradable version of each contract.
    7a.Marketing - Write down article about OpenBrushWe are going to write the article abot the importance of OpenBrush and applied usage of it. Moreover, 727.ventures team will promote it in Twitter, Medium etc.
    7b.Marketing - Create 2 educational video for OpenBrushWe are going to work on educational video materials for OpenBrush and ink! Community. We see a huge gap in knowledge, understanding, and vision for the whole community in that sphere. Moreover, 727.ventures team will promote it in Twitter, Medium etc. We will create a lower entry threshold for newcomers by this educational program.

    Milestone 7. AssetPallet chains extensionโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a report of how to transition from PSP22 on contract level to PSP22 on pallet level. Add documentation about the workflow of PSP22 and Statemint parachain.
    1.Implement AssetPallet chain extension on substrate level to work with pallet-assets in runtimeWe will implement a chain extension on the substrate level that allows interaction of contract with pallet-assets. Any network with that chain extension allows developing contracts that store information regarding fungible tokens on the pallet-assets level instead of the contract level. That allows to reduce the size of PSP22 contracts and provide SCM support by default for fungible tokens.
    2.Implement AssetPallet chain extension in OpenBrushUsage of chain extension requires implementation on the level of the contract too, so we will implement it in OpenBrush. Anyone will be able to reuse chain extension.
    3.Implement PSP22 with that chain extension in OpenBrushThe OpenBrush will provide a default implementation for PSP22 implemented via AssetPallet extension. It will behave in the same way as PSP22 but the information will be stored on the level of pallet-assets.
    4.Create standards for AssetPallet Chain Extension and for PSP22Asset extensionThe AssetPallet extension can be used by anyone and on any network. It requires the standardization of the methods and data types that are supported. We will create standards for that in the PSP repository.
    5.Advanced ink! unit testing frameworkAdd support to the contract deployment, chain extension registration, and smart contract cross-contract calls into the ink! unit test framework.
    6.Support of XCM and cross transferring of PSP22 tokensIf the support of XCM by the pallet-assets is not ready, we will participate in the development process to speed up it. The final step is that anyone will be able to transfer assets of pallet-assets, that are managed by the contract, between parachains freely.
    7.Add support for ink! 4.0We will update OpenBrush to be compatible with ink! 4.0 releases
    8a.Marketing - Create 2 educational video for OpenBrush/ink!We are going to work on educational video materials for OpenBrush and ink! Community. We see a huge gap in knowledge, understanding, and vision for the whole community in that sphere. Moreover, 727.ventures team will promote it in Twitter, Medium etc. We will create a lower entry threshold for newcomers by this educational program.
    8b.Marketing - The website upgradeWe are going to update out current website and add more specific things to improve the search for OpenBrush website in Google.

    Future workโ€‹

    Milestone 8. UniquePallet/RMRKPallet chain extensionโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a report regarding size reductions. We will create documentation and standards to describe the workflow of Non-Fungible token chain extension, how to reuse it and how it works.
    1.Create PSP for NFT on RMRKWe plan to create a new standard for NFT tokens based on RMRK. We will work with the RMRK team on the finalization of the standard. We will try to be compatible with PSP34. Based on the result of the work we will decide to create the chain extension for the unique-pallet or for the rmrk-pallet.
    2.Implement chain extension for NFT on substrate levelIn the same way as for the AssetPallet extension, we plan to implement UniquePallet/RMRKPallet chain extensions on the substrate level. Based on the cooperation with the RMRK team we will decide how better implement Non-Fungible tokens.
    3.Implement chains extension in OpenBrushImplementation of contract versions of the UniquePallet/RMRKPallet chain extension. Anyone will be able to call the logic of pallets from the contract.
    4.Implement NFT contract via chain extensionsOpenBrush will provide a default implementation of contracts that are implemented via according chains extensions.
    5.Refactoring of trait system in the ink!Refactoring of trait system in the ink! to support default implementation inside of traits. It should improve the developer's experience with traits and simplify its usage.
    6.Marketing - Create 4 educational video for OpenBrush/ink!We are going to work on educational video materials for OpenBrush and ink! Community. We see a huge gap in knowledge, understanding, and vision for the whole community in that sphere. Moreover, 727.ventures team will promote it in Twitter, Medium etc. We will create a lower entry threshold for newcomers by this educational program.
    7.ink! storage docsThere is no documentation with clear description of how the storage works within ink!. As our team was the one doing the refactoring of ink! storage, we will create a comprehensive documentation on how the storage works in ink! 4, as well as detailed comparison on what was changed in comparison to ink! 3 storage, including examples of usage.

    Milestone 9. Multi token chain extensionโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a report regarding size reductions. We will create documentation and standards to describe the workflow of Multi token chain extension, how to reuse it and how it works.
    1.Implement chain extension for Multi token in substrate levelIn the same way as for the AssetPallet extension, we plan to implement MultiPallet extension on the substrate level. We hope that Paratoken Standard will be accepted and implemented and we will be able to integrate with it.
    2.Implement chains extension in OpenBrushImplementation of contract versions of the MultiPallet chain extension. Anyone will be able to call the logic of multi asset pallet from the contract.
    3.Implement multi token contracts via chain extensionsOpenBrush will provide a default implementation of contracts that are implemented via according chain extension.
    4.Reduce the size of the contracts more(investigation and implementation)After the support of main chain extensions, we plan to focus on the contract size reduction of all contracts in OpenBrush. We plan to contribute to ink! and participate in according issue.
    5.Advanced documentationFor the better understanding, we will post on the OpenBrush website - the clear technical checklist to become an ink!/OpenBrush engineer. It will attract more developers and builders in the ecosystem

    NOTES: During each milestone, we also will maintain OpenBrush to be compatible with a new version of ink! and contract-pallet:

    Future Plansโ€‹

    After, this Grant, we will create a grant related to upgradable contracts.

    We're going to make a strong impact in the community, making ink! simple and convenient for developers.

    Additional Information โž•โ€‹

    In the roadmap, you can see what was already done. Currently, we're on the 5th milestone. The 5th milestone depends on review from ink! team so we started 6th milestone in parallel.

    We`re organising the first WASM conference in the whole Polkadot ecosystem. This event is a part of Open Brush marketing strategy.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    We have decided to describe a full roadmap of an OpenBrush here, with estimates. However, the funding we request at this stage is for milestones 3-5.

    Previous workโ€‹

    Milestone 1 - Implement reusable basic contracts in ink!, similar to Openzeppelinโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will enhance inline documentation, and create a tutorial on how to import/customize contracts.
    0c.Testing GuideWe will add unit tests to cover all basic logic and integration tests with Redspot, to verify that all works via contract-pallet
    1a.Fungible token(Erc20)We will implement reusable Erc20 analog on ink!
    1b.Non Fungible token(Erc721)We will implement reusable Erc721 analog on ink!
    1b.Multi token(Erc1155)We will implement reusable Erc1155 analog on ink!
    2a.AccessControlWe will implement reusable AccessControl analog on ink!
    2b.OwnableWe will implement reusable Ownable analog on ink!

    Milestone 2 - Simplify usage of library. Add a new features which extend ink!. Provide macroses that will allow creation of your own base implementationโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will enhance inline documentation, update previous documentation based on simplifications, documentation for new features.
    0c.Testing GuideWe will test macros, update tests according to new features, simplifications.
    1.Remove boilerplate codeWe will provide a macro which will allow to remove boilerplate during usage of library(Library provides implementation on rust level in internal trait. User must reuse internal implementation with ink! messages. Our macro will simplify it). It will simplify the code structure and usage.
    2.Derive for storagesWe will provide a derive macro to generate implementation for storage's structs. It will simplify integration of fields inside of struct and implementation of storage's traits for that fields.
    3.Support default implementation in external traitsWe will add mnemonic support of default implementations inside of trait definition(traits defined via #[ink::trait_definition]). It is mnemonic, because under the hood we will generate internal trait with default implementation that will be used in external trait.
    4.Support of modifiersWe will add support of modifiers, like in Solidity. User will be able to mark some function to use modifiers and it will simplify the code.
    5.ReentrancyGuardWe will add implementation of ReentrancyGuard
    6.Implement additional useful contractWe will implement PaymentSplitter, TimelockController and etc.

    Current work - Scope of this Grantโ€‹

    Milestone 3. Reduce the size of Erc20 contractโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide a report of how much each optimization reduced the size.
    1.Reduce the size of Erc20 contractNow the most critical moment with ink! is the huge size of contracts. This issue described the problem very well. The parity team works in this direction, and we want to help with ink! side. The ink! team created issue 906, 916 and 910. We want to briefly(not full change, only minimal changes to reduce the size) implement them and provide a report(re-working data structure, reducing monomorphization, using dynamic dispatch in some cases). Based on this report, the ink! team can decide how better to implement them and which part is more critical. During the implementation, we will build examples with our version of ink! (also maybe we will modify some sub-crates). So the output of this work is a report and custom version of ink!. The code can be reused, or if ink! team agrees we can try to implement these issues by ourselves later as separate work.

    Milestone 4. Pre-release - Standardization of tokens contracts. Implement extensions for contracts. Documentationโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide inline documentation for macros, create a tutorial on how to use macros in your own project, with a detailed description of how it works inside.
    0c.Testing GuideWe will add more tests to cover all macros, update tests according to new changes.
    1.Create Proposal for Fungible tokenWe will create a proposal for standardization of Erc20 token in case of ink! and contract-pallet. Based on the final decision regarding the proposal update the implementation in library.
    2.Implement extensions for tokensWe will implement extensions for Erc20, Erc721 and Erc1155 tokens.
    3.Create Proposal for Non Fungible token and Multi tokenWe will create proposals for NFT and multi token, when proposal for FT token will be approved. Based on the decisions of these approves, we will update implementation in library.
    4.Use original ink! instead of our ownWe will use ink! 3.0-rc6 version(or a new one if it will be compatible) instead of our own version of ink!.
    5.Refactor the contracts to be compatible with PSPsWe will refactor the contracts according to the PSP.
    6.Refactor the structure of the OpenBrush to provide agnostic traitsWe will refactor the structure of the OpenBrush to provide traits for each implementation of the contract without restriction and implementation related information:
    - Traits will be defined in a separate module.
    - The default implementation of that trait for a contract will be provided via unstable feature #![feature(min_specialization)].
    - We will provide a new macro to generate a wrapper around a trait. That wrapper can be used for cross-contract calls. So the user is enough of the trait definition to do a cross contract call.

    Milestone 5. Release - Contribution to inkโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will provide inline documentation, example of usage of extensions.

    1) Open zk-rollup architecture Developers who want to participate in the Polkadot ecosystem do not need to invest in their own zk-rollup technology alone so that more developers can participate in the development of zkapp.

    2) increase scalability The off-chain zkapps greatly expands the scalability of the Polkadot/Substrate.

    3) Modularity The architecture of Open rollup is suitable for different proof and verify protocols, and can adapt to zkapps of different ZK protocols in the future

    1) The application developers that are in search of scaling their blockchain application, for example, the payment application. 2) The game developers who do not want to interact with the chain frequently only need to submit in batches for a period of time, which saves the cost of using the chain and improves the user experience.

    There are many zk-rollup projects, such as zksync, starknet, hermez, plonky2, they are basically in the Ethereum ecosystem. They are all operated by a central operator, and in our protocol, each zkapp is an operator.

    Orochi Network's proposal for research and development MPC ECDSA

    • Team Name: Orochi Network
    • Payment Address: 167Zj4mv1jBTzJimSe7LngcRS7SBixsx3ZSCFr45Eo1SjWCY (USDT Polkadot)
    • Level: 1

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Users are now able to take advantage of the highest security feature similar to a cold storage while experiencing flexibility and convenience of the mobile app at minimal cost. Orosign is a self-managing custodial Mobile App for digital assets/identity that suits all demands of Web3.

    Project Detailsโ€‹

    Orosign project utilize cryptographic primitives and Multiparty Computation (MPC) to help people manage/secure their digital assets, it could provide highest security meanwhile friendly to end-users. Orosign provides following features:

    • Gasless Multi-signature: We use ECDSA proofs to perform off-chain voting to manage multi-signature wallet.
    • Gaming & NFT: Support gaming by providing automation transaction signing for Web3 game, this wallet can manage and display NFTs.
    • ZeroKey: A MPC based wallet, we build ECDSA on top of MPC to secure the signing process where user can perform the signing without any actual private key.
    • Web3 Passport: Support Proof of Carrying Data (PCD) for the Web3 authorization.
    • Account Abstraction with MPC: You could see the raise of Account Abstraction at the smart contract level, we want to take it a bit further with MPC. We want to provide a MPC based account abstraction for the end-users, so they can manage their digital assets in a more secure way.

    Ecosystem Fitโ€‹

    • Non-custodial Users are holding their own digital asset that meant the encrypted private keys is stored in their crypto wallet and hold the major secret shares in MPC wallet. Orosign was design to make sure no one able to touch people digital asset even Orochi Network.
    • High Customizability In gasless Multi-signature Wallet and MPC Wallet, user can customize number of participants and the threshold to perform signing process.
    • Highest Level of Security Orosign can be provide the first MPC Wallet on Polkadot.
    • NFT & games optimization Automatic showcase for all NFT collectibles, and support automation transaction signing for Web3 game.

    What is the benefit of this solution compared to others?

    • Multi-signature and MPC Wallet enable highest level of security in co-ownership for vast majority of Polkadot's users.
    • Providing the first MPC Wallet as a mobile application on Polkadot
    • Orosign is building toward the vision of Web3 passport, it allos user to manage their digital identity and assets in one place.

    Is this meant to be an enterprise-grade security wallet such as this SaaS wallet?

    • Orosign is a self-custodian wallet, we offer enterprise-grade security for retail and semi-retail users.

    Will it be cross-chain compatible or is it only meant for substrate chains?

    • In the budget of this proposal we only able to support Polkadot's chain and its parachains. We will consider to support other chains in the future.

    Can you further expand on the technical details of the wallet in the deliverables?

    • We implement DKG to generate secret shares that will be used to perform signing process without actual private key.
    • User will hold let's say 3 shares (2 sign shares and 1 backup) of 5 shares (Orochi Network hold 2). We created a threshold signature 3 of 5, it's required at least 1 share from user to perform transaction co-signing.
      • Orochi Network can't perform the signing process.
      • User can perform the signing process with or without Orochi Network.

There are 3 DSAs were used by Polkadot: secp256k1, ed25519, sr25519. Before we can build a MPC based DSA, we need to research the algorithm and figure out how we could fit MPC into it. You may notice that each curve have different parameters and different field, after the research we can specify how MPC should be implement without harm its security.

    • Implement a node of MPC's distributed network to perform MPC.
    • Implement API interface for distributed system, allow Wallet API to connect to MPC nodes.
    • Integrate wallet API with node's RPC, provide back-end for Orosign front-end.
    • Integrate wallet API with Orosign front-end, allow users to use MPC wallet.
    • Integrate MPC in both front-end and back-end of Orosign, allow user to perform transaction signing with mobile device.
    • Support PCD (Proof of Carrying Data)

    Additional Information โž•โ€‹

    We do research about MPC, especially ECDSA threshold signature for 1 year, publish several articles on our blog (docs.orochi.network). Drafting the paper to consider right method to Implement threshold signature (ECDSA), considering different methods to for implementation. Have some related work on MPC ECVRF which is shared some similar primitives to ECDSA.

    Milestone 1: Create a Rust client library for drandโ€‹

    While there exists one drand Rust client library, it hasn't been updated in 2 years.

    1.Example palletWe will create a pallet that integrates the drand client library from Milestone 1, and write a sample pallet that uses its features (eg. return a message from a list of messages at random, based on the public randomness it retrieves via the API).
    2.Randomness verificationThe pallet will be able to verify round randomness via the chain randomness information.
    2.Example chainWe spin up a testing chain to demonstrate how such a pallet works.

    Future Plansโ€‹

    Once randomness is available to Substrate developers, we would be interested to write a client that actually participates in the drand protocol. It may make sense for a common-good parachain to participate as a member of League of Entropy. We recognize the lack of accountability and other issues that can arise with an anonymous team maintaining such an important and foundational ecosystem component like a common-good parachain,, and we are open to discussion solutions relating to the development and maintenance of it.

    pallet started here: https://github.com/kabocha-network/pallet_supersig/tree/polkadot-v0.9.16

    Description in trello ticket: https://trello.com/c/qi4Nf2YT

    *We are now working on the Supersig pallet (pallet_supersig). This pallet will benefit multisig users of Substrate based chains.

    The Supersig pallet is a multisig with super powers. It allows you to add and remove members of the multisig. It extends the capabilities of a multisig so it can be fit for governance of larger funds.

    A multisig transaction acts more like a treasury proposal. And the signatures become votes, with a quorum that can be changed (but in the MVP is fixed to simpleMajority).*

    Development Roadmap ๐Ÿ”ฉโ€‹

    This section should break the development roadmap down into milestones and deliverables. To assist you in defining it, we have created a document with examples for some grant categories here. Since these will be part of the agreement, it helps to describe the functionality we should expect in as much detail as possible, plus how we can verify and test that functionality. Whenever milestones are delivered, we refer to this document to ensure that everything has been delivered as expected.

    Below we provide an example roadmap. In the descriptions, it should be clear how your project is related to Substrate, Kusama or Polkadot. We recommend that teams structure their roadmap as 1 milestone โ‰ˆ 1 month.

    For each milestone,

    pallet_supersig public methodsโ€‹

    Create a supersig

    create_supersig will create a supersig with specified parameters, and transfer an existencial deposit from the creator to the generated supersig account, to bring the account to life. The dispatch origin for this call must be Signed.

    The threshold is currently u128, but will be Enum.

    pub fn create_supersig(
       origin: OriginFor<T>,
       members: Vec<T::AccountId>,
       threshold: u128, 
      )

    Submit a call to a specific supersig

    submit_call will create a proposal on the supersig, that members can approve. This will lock an amount that depend on the lenght of the encoded call, to prevent spam. The dispatch origin for this call must be Signed, and the origin must be a supersig member.

    pub fn submit_call(
       origin: OriginFor<T>,
       supersig_id: T::AccountId,
       call: Box<<T as pallet::Config>::Call>,
      )

    Vote for a call in the supersig

    approve_call will add a positive, unique vote to the specified call proposal. If the numbers of votes on this proposal = SimpleMajority (51%), then the call is executed. The dispatch origin for this call must be Signed, and the origin must be a supersig member.

    pub fn approve_call(
       origin: OriginFor<T>,
       supersig_id: T::AccountId,
       call_index: CallIndex,
      )

    Remove a call from the supersig

    remove_call will remove a call from the poll. For trensparency reasons, the votes won't be removed. This will also unlock deposited funds. The dispatch origin for this call must be Signed by either the supersig or the account who submitted the call.

    pub fn remove_call(
       origin: OriginFor<T>,
       supersig_id: T::AccountId,
       call_index: CallIndex,
      )

    Add member to the supersig

    pub fn add_member(
          origin: OriginFor<T>,
       supersig_id: T::AccountId,
       call_index: CallIndex,
      )

    Remove member from the supersig

    pub fn remove_member(
          origin: OriginFor<T>,
       supersig_id: T::AccountId,
       call_index: CallIndex,
      )

    Milestone 1 to make a working, secure and usable pallet_supersig v0.1.0.

    Milestone 2 will make the Supersig as visible of an experience within the polkadot js UI as Multisig, The PR will be made, and if there is a blocker, then the apps.decentration.org fork will house the feature.

    Milestone 3 Will get feedback and make some improvements. One improvement is adding a "Super Beneficiary" option that allows a threshold of 2/n only if the Super Beneficiary is involved in the transaction. Else the transactio will default to a superMajority. This allows for greater than the usual 2/3 multisig, but without loss of security.

    โšก If any of your deliverables is based on somebody else's work, make sure you work and publish under the terms of the license of the respective project and that you highlight this fact in your milestone documentation and in the source code if applicable! Teams that submit others' work without attributing it will be immediately terminated.

    Project Overview ๐Ÿ“„โ€‹

    This grant request is a follow-up on a previous agreement that has been terminated to allow for a value-first approach for the delivery of PANIC increments.

    Overviewโ€‹

    PANIC by Simply VC is an open-source monitoring and alerting solution for blockchain node operators. PANIC monitors a node operatorโ€™s setup, and sends relevant alerts via multiple alerting channels. The main objectives are to give node operators insight about the state of their systems, and to promptly raise alerts in case of an issue that may degrade the availability of their service.

    This grant request revolves around expanding the base tool together with the UI to cater for high priority Substrate metrics. This will allow PANIC users to monitor and be alerted on a growing number of metrics. Below is a table of what is in scope for this grant:

    Table 1โ€‹

    TypeMetric
    ConsensusBlocks authored
    ConsensusValidator status in consensus (active, disabled, elected)
    ConsensusGrandpa consensus rounds

    NodeSyncing status
    NodeBest block height
    NodeFinalised block height
    NodeSync target height
    Node StashNew Controller
    PayoutPayout Occurred

    PANIC is built around the needs of our own node operations team. We believe in dogfooding as it allows us to better assess the strengths and weaknesses of what is being built and ultimately provide a better product for external node operations teams.

    Project Detailsโ€‹

    Mockups of UI componentsโ€‹

    For the scope of this iteration, the installer will remain mostly unchanged, with the exception of the Alerts Configuration page. During the installation process, the node operator can manage out-of-the-box thresholds and severities for a list of alerts that will include the metrics listed in Table 1

    The first iteration of the UI includes a high-level dashboard from which node operators will be able to review all implemented alerts across all chains setup during installation. Also provided is a low-level system metrics dashboard which displays real-time data related to the host systemsโ€™ performance. The UI will remain unchanged but node operators will be able to view new alerts on the metrics listed in Table 1.

    Technology stack being usedโ€‹

    • Alerter - Python
    • UI (backend) - Node.js, TypeScript
    • UI (frontend) - TypeScript, Stencil JS, Sass
    • Docker

    Core components and architectureโ€‹

    PANIC is a Publisher-Subscriber system consisting of a number of components where each component is either a publisher, a subscriber or both. PANIC uses RabbitMQ to forward messages between components classified the table below:

    Table 2โ€‹
    ComponentsDescription
    MonitorsThe role of a monitor is to track the status of a monitorable (node/repository/network) by periodically obtaining a set of metrics from various sources (such as prometheus/rpc endpoints) and forwarding these metrics to RabbitMQ
    Data TransformersEach data transformer listens to metric data from the monitors. Depending to what monitorable the data belongs to, the data transformer outputs two sets of data, one for saving and another for alerting
    AlertersThe role of the alerters is to load the alert rules set up during installation and listen to transformed data from the data transformer. When this is received, an alerter checks the alert rules and raises alerts with the appropriate severity when needed
    Data StoresThe data stores receive transformed data and store the metric data inside Redis and MongoDB. Redis data will be used to load the current metrics state in the UI dashboards, whereas MongoDB data will be used to load historic data on the UI
    Alert RouterThe role of the alert router is to forward the raised alert to the appropriate channel, depending on the severity-channel mapping set during installation
    Channels ManagerThe channels manager receives alerts from the alert router and forwards these alerts to the channel determined by the alert router. The channels manager contains all the logic required by PANIC to communicate with a specific channel

    PANICโ€™s architecture diagram can be found here.

    Ecosystem Fitโ€‹

    PANICโ€™s main objective is to become the go-to tool for node operators active on various chains, including Substrate-based ones. PANICโ€™s focus is on alerting in the event that an issue arises that directly impacts the service being maintained. This grant request is against the investigation, development, testing, and delivery of additional metrics with the goal of providing node operators with a more complete monitoring and alerting solution as per Table 1.

    Currently a number of node operators are using other tools, such as Grafana in collaboration with Alertmanager, but this is not without fault. Such solutions require considerable setup effort and offer no default configurations. On the other hand, PANIC is built with ease of use in mind. The node operator is taken intuitively through the installation process which is clean and quick, with out-of-the-box thresholds and severities that can be configured if required. Once the installation is finalised, the UI will be made available with visual representations of alerts in line with the setup installed.

    At Simply VC we strive to keep our external stakeholders aware of product progress. For PANIC, this is achieved by the issue of an end-of-month progress report, which includes our latest releases, changes to the team structure and way of working, current priorities, and what features will be tackled in the short-term. Also included is a high-level roadmap to allow for longer-term visibility.

    Initial investigationโ€‹

    Following an initial investigation, we envisage that for Substrate node monitoring and alerting, PANIC will operate as follows:

    1. When the Monitors Manager Process receives the configurations, it starts as many Substrate Node Monitors as there are Substrate configurations to be monitored.
    2. Each Substrate Monitor extracts the Substrate data from the node's websocket url and forwards this data to the Substrate Data Transformer via RabbitMQ.
    3. The Substrate Node Data Transformer starts by listening for data from the Substrate Node Monitors via RabbitMQ. Whenever a Substrate node's data is received, the Substrate Node Data Transformer combines the received data with the Substrate node's state obtained from Redis, and sends the combined data to the Data Store and the Substrate Node Alerter via RabbitMQ.
    4. The Substrate Node Alerter starts by listening for data from the Substrate Node Data Transformer via RabbitMQ. Whenever a Substrate node's transformed data is received, the Substrate Node Alerter compares the received data with the alert rules set during installation, and raises an alert if any of these rules are triggered. This alert is then sent to the Alert Router via RabbitMQ .
    5. The Data Store also receives data from the Substrate Node Data Transformer via RabbitMQ and saves this data to both Redis and MongoDB as required.
    6. When the Alert Router receives an alert from the Substrate Node Alerter via RabbitMQ, it checks the configurations to determine which channels should receive this alert. As a result, this alert is then routed to the appropriate channel and the Data Store (so that the alert is stored in a Mongo database) via RabbitMQ.
    7. When a Channel Handler receives an alert via RabbitMQ, it simply forwards it to the channel it handles and the Node Operator would be notified via this channel.

    For Substrate network monitoring and alerting, PANIC will operate as follows:

    1. When the Monitors Manager Process receives the configurations, it starts one Substrate Network Monitor per chain and keeps the configurations updated. A Substrate Network monitor chooses the first syncing and accessible node it finds to retrieve network metrics.
    2. Each Substrate Network Monitor extracts the Substrate network data from the selected substrate node's websocket url endpoint and forwards this data to the Substrate Network Data Transformer via RabbitMQ.
    3. The Substrate Network Data Transformer starts by listening for data from the Substrate Network Monitors via RabbitMQ. Whenever a Substrate network's data is received, the Substrate Network Data Transformer combines the received data with the Substrate Network's state obtained from Redis, and sends the combined data to the Data Store and the Substrate Network Alerter via RabbitMQ.
    4. The Substrate Network Alerter starts by listening for data from the Substrate Network Data Transformer via RabbitMQ. Whenever a Substrate Network's transformed data is received, the Substrate Network Alerter compares the received data with the alert rules set during installation, and raises an alert if any of these rules are triggered. This alert is then sent to the Alert Router via RabbitMQ .
    5. The Data Store also receives data from the Substrate Network Data Transformer via RabbitMQ and saves this data to both Redis and MongoDB as required.
    6. When the Alert Router receives an alert from the Substrate Network Alerter via RabbitMQ, it checks the configurations to determine which channels should receive this alert. As a result, this alert is then routed to the appropriate channel and the Data Store (so that the alert is stored in a Mongo database) via RabbitMQ.
    7. When a Channel Handler receives an alert via RabbitMQ, it simply forwards it to the channel it handles and the Node Operator would be notified via this channel.

    Future Plansโ€‹

    We see PANIC as being the go-to tool for node operators active on Substrate, Cosmos, and Chainlink networks. For this to be achieved we will continue to introduce more metrics for monitoring and alerting from various data sources. Considerable time and effort will be invested in the UI to introduce new functionality such as MFA and low-level dashboards for additional visual representations on node, governance, and consensus data.

    Work already doneโ€‹

    In its current state, PANIC provides node operators with:

    1. A base tool that monitors host systems that the Substrate/Cosmos-SDK/Chainlink nodes are running on.
    2. Monitoring and alerting on:
      • Chainlink nodes
      • Chainlink contracts
      • EVM nodes
      • GitHub repositories
      • DockerHub repositories
    3. Channels designed to notify node operators of the status of monitored metrics and any issues that might require immediate attention :
      • Telegram
      • Slack
      • Email
      • Twilio
      • PagerDuty
      • Opsgenie
      • Console
      • Log files
    4. Basic control over the alerter (such as mute alerts and check status) via Telegram bots and Slack apps.
    5. A quick installation through an intuitive UI setup and configuration process.
    6. Out-of-the-box alert thresholds for metrics monitored and associated severity levels of alerts (Info, Warning, Major, and Critical), customisable by node operators.
    7. A UI which consists of a high-level dashboard from which node operators can review all alerts together with a low-level dashboard which allows node operators to review the performance of their host infrastructure.

    May 2022 will see an additional release which will allow node operators to get alerted on high priority metrics for Cosmos based chains.

    Pallet-dPoS for Parachain Staking

    • Proposer: Moonbeam Network
    • Payment Address: 0x9a66721302d9f30a9d11cf48a09c7ef1a842b5c8

    Project Overview ๐Ÿ“„โ€‹

    Moonbeam is an Ethereum-compatible parachain built with Substrate. Since January 2021, Moonbeam's runtime developer team has written and maintained a delegated Proof of Stake (dPoS) implementation designed specifically for parachains called parachain-staking. To make this code useful for other parachain teams, Moonbeam is applying for ecosystem funding to extend, benchmark, and document its dPoS implementation.

    Backgroundโ€‹

    In the Polkadot consensus model, parachains have different requirements and constraints than the relay chain. While frame/pallet-staking offers many features necessary for relay chain consensus and shared security, it is overkill for parachains, which operate with more limited execution resources.

    Instead of running an on-chain election, parachain-staking implements direct delegation with a bounded number of nominations per AccountId (maximum of Config::MaxCollatorsPerNominator per account). In this paradigm, token holders (nominators) express exactly which collator candidates they would like to support and with what quantity of stake.

    There is a new round every <Round<T>>::get().length = 600 blocks. At the start of each round, the top <TotalSelected<T>>::get() = 16 collator candidates (in terms of total backing stake) are chosen to be in the active collator set. At every block, a subset of this active collator set is chosen pseudorandomly by the author-filter pallet as valid block authors. Only valid block authors can produce blocks.

    Block authors are logged via the set_author_inherent method in the author-inherent pallet. The logic in this runtime method reports each block author to parachain-staking, which distributes inflation rewards after a 2 round delay.

    • Total Estimated Duration: 6 weeks
    • Full-time equivalent (FTE): 2 FTE
    • Total Costs: 30000 DAI

    Both milestones will be worked on in parallel, but UI development will lag changes to the pallet implementation.

    Milestone 1: Improve Parachain-Staking Palletโ€‹

    • Estimated Duration: 4 weeks
    • Costs: 20000 DAI

    In addition to updating Rust crate-level docs and outdated user-level docs in step (5), we will also pursue the following changes to the current parachain-staking implementation:

    1. Benchmark to derive transaction weights. This work has been started in this PR.

    2. Security Research Labs reported two critical vulnerabilities in parachain-staking: (i) total locked balance was not updated in {collator, nominator}_bond_more leading to a potential underflow error (which could trigger excessive issuance) (ii) bounded number of nominations per collator allowed any account to fill the slots with the minimum nomination thereby preventing higher nominations.

    3. The inflation logic implemented in parachain-staking is minimal. Instead of integrating pallet-staking's reward curve, the current implementation calculates per-round inflation derived from an annual inflation rate. Although the inflation rate can be updated by governance (sudo as of now), it is constant. Some parachain teams (i.e. Kilt) have requested configurable inflation that uses pallet-staking's reward curve instead because it has been audited and reviewed more closely.

    4. Moonbeam reserves 30% of inflation for future parachain bond(s). To support this functionality, parachain-staking added the storage item ParachainBondConfig. This storage item is updatable by the root origin; it configures the percent (30%) of inflation reserved as well as the AccountId which receives the reserved funds. This feature is convenient for parachains in the Polkadot ecosystem, all of which must pay rent to the network by locking funds in the parachain bond.

    The Parami Protocol

    • Team Name: The Parami Team
    • Payment Address: 1ET2d5D2aDebVdrV21d6h9w2kuYV4fthv
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The goal of Parami Protocol is to build a blockchain-empowered fair and transparent win-win private domain traffic advertising alliance, connecting the majority of advertisers, traffic owners and users, removing intermediaries, improving settlement efficiency, allowing users to take back their own digital sovereignty, and the revenue of all parties involved in digital advertising.

    Parami uses Substrate as the blockchain development framework, mainly for two reasons. From the technical level, Substrate framework is a general blockchain development framework launched by Polkadot. Substrate contains all the components needed to build a blockchain, including a p2p network, consensus mechanism, distributed database, transaction queue, and core runtime. The modulized framework provides a powerful tool for chain or side-chain development.

    On an ecological basis, the number of Polkadot developers and projects is growing at a rapid pace. The Web3 Foundation currently funds over 100 projects, most of which are related to Polkadot or Substrate. In terms of eco-applications, there are already nearly 100 projects based on Substrate. More and more talented developers and teams are joining the Polkadot ecosystem. These Web3.0 projects will all have the need for tokenized marketing, thus becoming an important business partner of Parami.

    The Parami protocol will provide a DID-based tokenized advertising preference solution for the whole Polkadot ecosystem, with its power of the parachain & relay-chain mechanism.

    We have done many attempts to combine blockchain with digital advertising, and have been bothered by traditional digital advertising. We have been keeping considering some questions:

    • How can users benefit from the advertising industry?
    • How can users re-gain their control of self digital sovereignty, and be freedom from digital exploitation?
    • How can participants in the digital advertising industry can mutually benefit from each other?

    So we come up with the Parami Protocol, an identity-driven and data-driven solution to digitial advertising.

    From the perspective of the advertising industry, the blockchain technology can get fairness and autonomy. On the other hand, from the blockchain's view, tokenized advertising can bring more opportunities and value growth to the web 3.0 ecosystem.

    Project Detailsโ€‹

    The main participants of the Parami protocol are advertisers and users. The full set of services is achieved through the cooperation of multiple components.

    Project Details

    Parami components include Runtime, Off-chain worker, RPC Interface. Runtime and Off-chain workers work together to implement the core of Parami. The core node code and is maintained by Parami, the nodes will be maintained by the community.

    Advertisers can create ad requests by accessing the Advertiser Portal, which interacts with RPC Interface.

    Users access various types of ads through different ad media. The social integration SDK will fetch and display Ad in IM explorer, then track and upload user interaction data to Advister server.

    Ad metadata is divided into two categories, the on-chain part and off-chain part(IPFS part).

    On-chain ad metadata contains ad parimary key and reward info:

    • issuerdid: issuer did of the ad
    • adid: ID of the ad
    • totalfund: all the fund has been deposited
    • remainfund: the maining fund has been deposited.
    • base: the basic reward for a single ad interaction.
    • bonus: the highest stardard of the bonus reward.

    Off-chain ad metadata will be stored on IPFS, including all other basic ad metadata:

    • id: ID of the ad
    • adomain: ad domain name
    • bundle: unique ID of app where ad is shown
    • url: ad jump url
    • tags: string array of ad topic
    • lang: language code of the ad using ISO-639-1
    • init: timestamp of the original instantiation of this ad
    • lastmod: timestamp of most recent modification to this ad
    • display: ad display data, including static picture url, or video links
    • ext: Optional vendor-specific extensions.

    Business Logicโ€‹

    All ads are pre-registered by advertisers via RPC Interface. So the advertisers know the ad's id, and set up the display of ad in its social platform or mobile apps.

    Life Cycle

    • When a user is to be shown an ad, the underlying RPC API SDK will be responsible for converting the ad id into ipfs metadata information to enable the display of the ad.
    • The SDK will then be responsible for passing the tracking data to the advertiser's server, which will be responsible for confirming the click and passing the confirmation information to the Parami's RPC Interface.
    • The off-chain worker is responsible for initiating reward transactions and updating the user's profile.

    The SDK will be a javascript library for advertisers to complete ad placements, with core functionality including๏ผš

    • DID registry: register/initialize new DID and profile for new user and bind the corresponding social platform ID.
    • DID read: get the DID according to the platform id.
    • Ad display: convert ad id to IPFS resources(metadata in JSON format)
    • Ad track: convert user interaction to track info.
    • Ad data upload: upload user ad data to advertiser server.

    Data Analysis Platformโ€‹

    Advertisers are always very concerned about the effectiveness of advertising. For this reason, we will develop a data analysis platform to facilitate advertisers to do further analysis of placement data and improve the effectiveness of advertising.

    Data Platform Prototype

    Ecosystem Fitโ€‹

    The Polkadot community alreay has a few standard DID solutions. The Parami DID will be a production-ready and domain-specific DID solution. We will add a referral system and use DID attributes as users' ad preference data.

    Projects like XCHNG, MAD Network, ADEX and Parpuys, use smart contracts to build infrastructure, which is expensive for normal users yet not appealing.

    Other projects, like Rebelai, adChain, are using blockchain to solve the problem of deception in traditional advertising, which neglects the value of user data and privacy.

    Parami combines DID with tokenized advertising, providing an Ad 3.0 paradigm to Web 3.0, decentralized privacy and data security, benefiting all participants.

    PESA - On-ramp/off-ramp to crypto/local currencies for Polkadot

    • Proposer: jdoshi1
    • Payment Address: 3K37k6BQ1JwAczAyNzckS4cGRqhpL6UgYJ
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    PESA is a decentralized cross-chain mobile money protocol that enables anyone to buy, sell, send, receive, lend, borrow - crypto, and mobile money (i.e. tokenized minutes, data, WiFi) globally using a phone number.

    Overviewโ€‹

    The goal of this project is to make telecom and financial services open and accessible to all. Anyone with a mobile phone can utilize PESA to:

    • Access carrier-independent voice, text, data & WiFi (mobile money)
    • Send/receive crypto and mobile money to/from any phone number
    • Buy/sell crypto and mobile money using a phone number
    • Lend, borrow, crypto assets using a phone number

    PESA is structured as a decentralized carrier and acts as a mobile money system. The traditional mobile money systems like m-pesa use phone numbers to uniquely identify users. Similarly, PESA uses tokenized phone numbers. A phone number is universal across chains and mapped to respective wallet addresses.

    PESA aims to serve as an on-ramp/off-ramp to crypto/local currencies for the Polkadot users, applications, and developers. This is enabled by allowing users to purchase tokenized voice, text, data and WiFi credits using credit card, cryptocurrencies and eventually cash. To achieve this, we can either create our own Substrate-based blockchain or Parachain or work with Parachains like Plasm, Moonbeam, Acala, etc.

    Project Detailsโ€‹

    As a first step, we are proposing creating a pallet to perform Phone Number to Address resolution, reverse resolution, and execute transactions such as send & receive - crypto tokens, mobile money (i.e. tokenized minutes, data and WiFi) using phone numbers.

    PESA palletโ€‹

    The goal of PESA pallet is to resolve the phone number to an address and allow the phone number to execute transactions - send, receive. It will be extensible to allow more functionality like lend & borrow, etc. Furthermore, it will be beneficial to dapps building financial systems (DeFi) including allowing unbanked users to onboard onto the system by just using a phone number.

    Interface and Designโ€‹

    The PESA pallet will expose the following callable functions:

    register - allows the user to register a Phone Number to its address

    resolve - allows any user to resolve a Phone Number to an address

    reverse_look_up - allows the user to look up Phone Number from an address. Provided the owner of the phone number/address opted to make it public.

    transfer - allows the owner of the Phone Number/address to transfer ownership of the Phone number to another address.

    send - allows the owner to send tokenized mobile money (i.e. mins, data and wifi) and other tokens built on the parachain(s) using the Phone Number

    Mockups of PESA Dapp

    • Register Phone number with wallet address

      Register

    • Verify Phone number ownership

      Verify

    • Send transaction

      Send

    Ecosystem Fitโ€‹

    All web and mobile wallets like Airgap and Polkawallet can use PESA pallet to resolve phone numbers and access other pallet functions mentioned above. DeFi applications can also use the pallet to allow users to access financial services using a phone number.

    Overviewโ€‹

    As Gavin mentioned in this CoinDesk article, WebAssembly is the future of smart contracts.

    However, WebAssembly, as the main Smart Contract in the substrate ecosystem, lacks the necessary infrastructure. Except for the lib of contracts provided by polkadot.js, there are no more third parties that can query the contract storage and interact with the package.

    PHP is one of the most popular development languages in the world, PHP is used by 77.8% of all the websites whose server-side programming language(https://w3techs.com/technologies/details/pl-php).

    Traditional PHP Website developers will lack the necessary SDK if they come into contact with the substrate, However, the lack of support for contracts in the current php-substrate-api makes it very difficult to use PHP as a development language to interact with the substrate.

    Therefore, this proposal is an extension of php-substrate-api to improve the practicability of this package further and increase support for smart contracts.

    Project Detailsโ€‹

    • Abi encode & decode, support contract metadata v0,v1,v2,v3,v4, this will be used to read and write smart contracts

    • Deploy wasm smart contract

    Example

    $api = new SubstrateRpc("websocket_or_http_url");
    $api->rpc->contracts->new("wasm_code", "gas limit","value");
    • Read contract values

    Example

    $api = new SubstrateRpc("websocket_or_http_url");
    $api->rpc->contracts->balanceOf("from","contract");
    • Send Contract transaction

    Example

    $api = new SubstrateRpc("websocket_or_http_url");
    $signer = new SubstrateRpc\Util\Keyring\Signer("privatekey");// or HD
    $api->setSigner($signer);
    $tx = $api->tx->contracts->transfer("to_address", 10000);
    $tx->signAndSend();

    Ecosystem Fitโ€‹

    PHP RPC Lib is PHP lib for query http rpc used by substrate.

    Overviewโ€‹

    • PHP is an extremely common development language in the web field, and currently there is no RPC library for substrate. I have already developed https://github.com/gmajor-encrypt/php-scale-codec in the previous grant. PHP RPC Lib is necessary to interact with the chain

    Project Detailsโ€‹

    • Sr 25519

    Since PHP does not have an encryption library for sr25519

    Will provide the following interfaces

    1. SR25519.NewKeypairFromSeed(seed)
    2. SR25519.sign(message),
    3. SR25519.verify(message, signature)
    • Send transaction

    Example

    $api = new SubstrateRpc("websocket_or_http_url");
    $signer = new SubstrateRpc\Util\Keyring\Signer("privatekey");// or HD
    $api->setSigner($signer);
    $tx = $api->tx->balances->transfer("to_address", 10000);
    $tx->signAndSend();
    • Read/subscribe HTTP/Websocket to RPC endpoints

    Example

    $api = new SubstrateRpc("websocket_or_http_url");
    $api->rpc->System->Heath();

    # or read storage 
    $api = new SubstrateRpc("websocket_or_http_url");

    Team's experienceโ€‹

    Daniel Olano is a Rust/Substrate Guru, and grinding full time to bring his brain child, Valibre, into fruition. He is a Colombian living in Berlin. He was first inspired to create Valibre to facilitate seamless fiat to crypto onboarding for users with varied financial literacy to combat the plague of hyperinflation across Latin America, but is excited to expand to failing fiat economies worldwide. He is currently facilitating the first Rust developer workshop in Spanish to increase visibility of Substrate and Polkadot to developers across LATAM.

    Stanly Johnson is based in Bangalore, India and is a seasoned software engineer across the stack of programming languages underpinning Web3 technologies, including Rust, Python, and Solidity. He is currently working as a runtime developer part-time with Valibre specializing in cross-chain transfers and escrow. Stanlyโ€™s passion for distributed systems stems from the opportunity it provides to reach everyone by eliminating systemic barriers.

    Samantha Robertson is a globetrotter with expertise across Business Development, Product, and Strategy. Samantha desended into the cypherpunk realm after working in product at an AI company, becoming dismayed by the necessary data extraction tactics to train AI models. Samantha is most excited to help build Valibre because she believes that it has the potential to onboard thousands of users to the blockchain without extensive education on technical intricacies. Samantha became a Polkadot stan when she grew fed up with gas fees and MEV. She has vast experience leading international teams and beleives that Web 3.0 technologies represent the future of multilateral cooperation.

    As part of the Substrate builders program we have completed the MVP implementation of the escrow and local rates pallet of the VLN parachain.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    We plan to have a public testnet of the Valibre Network (VLN) with a dedicated Matrix server for the PLIP community that can showcase the usage of the escrow system through a modified element.io chat UI. We will also revamp our website and documentation to educate developers on how to develop applications with the Valibre Open Runtime.

    Future Plansโ€‹

    Valibre's primary ambition is to be come the decentralized WeChat, a "super app" that promotes community engagement and provides access to any multilde of services and marketplaces powered by a decentralized infrastruture (PLIP.) We plan to execute this in two distinct ways over the short and long term:

    Short Term

    In conjunction with the development strategy explained above, we will aggressively ramp up community engagement efforts by executing a social media strategy across Telegram, Element, Medium, and Twitter. We have already been approached by two prospective partners to use our technology as the backend to power their decentralized communities. As such, we will build communities across social media and plan to promote a basic UI demo by the end of Q3 2021. Additionally, we have already successfully submitted a proposal to the Kusama Tresury and plan to submit two more proposals before the end of the year as a means to sustain our development as well as increase our visibility in the Kusama and Polkadot ecosystems.

    Long Term

    Alongisde the promotion of our project, our team is working to define a buisness development strategy that aligns with both our resource constraints as well as the needs of the broader ecosystem. This will unfold as either:

    Previous Funding and Support

    Valibre is the brainchild of Daniel Olano, and ultimately attracted the attention of Valiu, a stablecoin payments platform for users in Venezeula. Valibre was temporarily contracted by Valiu while also remaining an independent organization. We have created the basic foundation of PLIP with the required functionality of Valiu (remittances) as the basis of our inspiration, but now we are upgrading the foundations of PLIP to accomdate a broadend scope of use cases. This grant application is our first attempt seeking indepenent funding of any kind.

    polkadot-mempool-explorer-v2

    • Team Name: NA

    -Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    Mempool Explorer enables Polkadot ecosystem members to monitor pending transactions across several parameters and gain meaningful insights.

    Follow-up of Mempool Dashboard - Version 1

    • Link to the phase 1 project: medium

    However the project was created by a different team, Protofire. Currently it's not in working condition, the provided link https://mempool.dot.protofire.io/ doesn't work anymore.

    Overviewโ€‹

    Version 2 of mempool dashboard, is a tool to monitor pending transactions in Polkadot, Kusama, Westend, Rococo and you can add your customized network.

    Current issues with the initial implementation

    version 1 of the mempool dashboard is not in working condition. I took this opportunity to revive the project and create a next version of the original project by fixing the current issues, creating a new UI to enhance user experience and readability and improvements to the API.

    My first task was to understand the codebase, identify the current issue and provide a fix for it. After applying a few patches I was able to restore back to the original state, however still with few issues.

    Noteable issues

    • lack of proper code documentation ( it was difficult for me to understand the codebase initially )

    and set of exhaustive open issues https://github.com/muddlebee/polkadot-mempool-explorer/issues

    track of patches/fixes done till date - https://github.com/muddlebee/polkadot-mempool-explorer/commits/dev

    We have fixed majority of the issues already.

    What's in version 2

    • fix the existing issues
    • enable CI/CD deployment to the hosted servers and fix docker scripts
    • series of tutorials on polkadot-js APIs

    Currently there's a lack of proper tutorials/education materials for anything polkadot-js API related stuff other than the official docs. I would like to create an extensive tutorial on how to consume polkadot-js APIs (more details in Milestone section).

    why create a separate set of tutorials?

    • currently the polkadot JS docs is difficult for beginners with zero or less technical knowledge about the polkadot architecture to understand properly.
    • easy to learn and develop using polkadot JS APIs/SDKs as compared to substrate in Rust

    Project Detailsโ€‹

    Github: https://github.com/muddlebee/polkadot-mempool-explorer

    API : /api folder

    Frontend: /web folder

    API uses nodejs on top of polkadot js API

    Frontend uses React to render the transaction blocks in the UI

    Note We already have done 50% of the proposed work, and its live in the url below

    mempool-ui

    Technology stackโ€‹

    • javascript, nodejs, react
    • polkadot js API
    • docker

    Ecosystem Fitโ€‹

    Solution that would allow members of the Polkadot ecosystem to monitor information related to pending transactions.

    More details has been published in the phase 1 delivery report medium

    Tutorials for polkadot JS APIs will help educate folks who are not expert in Rust/Substrate and want to adopt JS first approach first. We have many examples of live webapps integrating polkadot JS APIs like wallets, tools etc.

    ECDSA for Polkadot JS

    • Proposer: @akru
    • Payment Address: bc1qccvrcny62epea360w0dvy2ynv90vz5luansmg9

    Project Description ๐Ÿ“„โ€‹

    Currently Polkadot/Substrate support three kinds of cryptographic primitives as MultiSignature data type:

    • Ed25519
    • Sr25519
    • ECDSA

    Unfortunately, right now Polkadot JS support first two only (enhancement issue: https://github.com/polkadot-js/common/issues/506). It's limiting using ECDSA keys for subkey CLI utility only, which makes user experience pipeline a bit difficult.

    Main aim of this project is providing comfortable environment for ECDSA key owners (Ethereum/Bitcoin holders) as same as for Sr/Ed25519 keys.

    Supporting wide range of cryptographic primitives is powerful side of substrate/polkadot ecosystem. This projects makes this side user-friendly introducing cryptographic primitives support on UI side.

    This project planned to be directly integrated into Polkadot JS which is part of Polkadot ecosystem.

    Plasm Network(https://plasmnet.io) is a scaling Dapps platform on Substrate. Plasm Network is planned to be a parachain in Polkadot ecosystem. Plasm token distribution model involves the use of a lockdrop approach in Ethereum and Bitcoin networks where Secp256k1 cryptography is a de facto standard. Plasm team is highly interested in making lockdrop participation process smoothly as much as it possible. ECDSA integration into Polkadot ecosystem is one of steps to makes it real.

    Project Description ๐Ÿ“„โ€‹

    Hardware wallets provide for end-user much more hight grade of security than traditional software wallets because of moving the private key out of general using PC. The most popular, Trezor (https://trezor.io/) and Ledger (https://www.ledger.com/), supports Ethereum / Bitcoin cryptography (ECDSA) by default. But ECDSA crypto is native for the Polkadot ecosystem too that makes hardware wallets fully compatible with Polkadot applications without any changes in hardware wallet firmware.

    This proposal improves already implemented software ECDSA keyring in PolkadotJS (https://github.com/w3f/Open-Grants-Program/pull/6) and planned to be directly integrated into Polkadot JS which is part of the Polkadot ecosystem.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    The DOT open source developer community is expanding rapidly, yet there is currently no way to easily monitor development progress across various projects that integrates with the DOT ecosystem. Keeping track of development progress across various projects and monitoring developer contributions can provide valuable insights into the evolution of DOT ecosystem. With data dispersed throughout Github, including contributors, commits, issues, repositories, and PRs, it can be challenging to grasp the overall progress of the DOT ecosystem.

    I am presenting PolkaFlow to the DOT community as the ultimate solution for visualizing and analyzing open source projects within the ecosystem. It offers a comprehensive view of activities of projects and insights into the ecosystem's trends. The project will allow users to gain insights into the development activity, code contributions, issue resolution, and community engagement of the DOT ecosystem through open source projects. This information will be displayed through various visualizations and charts, which will be accessible through a web-based application named PolkaFlow.

    Ecosystem Fitโ€‹

    Target audience

    The target audience for PolkaFlow can include developers, researchers, and enthusiasts who are interested in monitoring the development and activity of open-source projects on the DOT ecosystem. The platform's analytical tools and visualizations can provide valuable insights into the performance of various projects, making it useful for those who want to gain a better understanding of the ecosystem's progress and the direction it's headed in.

    Besides, by tracking the activity of commits history, and issue resolution PolkaFlow can help developers identify areas where they can improve and streamline their own development processes. By offering detailed analytics, PolkaFlow can become an essential tool for anyone who is interested in the development and progress of the DOT ecosystem.

    Evidence for the need

    • Increased Interest in DOT Ecosystem: The growth of the DOT ecosystem and the increasing number of open-source projects being developed on the protocol highlight the need for a tool that can monitor and analyze the performance of these open-source projects. PolkaFlow can provide valuable insights for the projects within the ecosystem.

    • Lack of Comprehensive Analytics: There is a lack of reliable and user-friendly tools that can provide detailed analytics and visualizations for open-source projects on DOT ecosystem. Besides, the demand for better analytical tools in the blockchain space is increasing, and developers and stakeholders are seeking tools that can help them monitor and analyze the performance of the projects. PolkaFlow fills this gap for the DOT ecosystem.

    • Historical and Trend Data:: PolkaFlow can provide a historical and trend data of the Github activity in the DOT ecosystem, allowing developers and project managers to see first hand how the ecosystem is growing, evolving, and changing over time. This data can be used to identify patterns, trends, and areas of improvement, leading to more informed decision making and better outcomes for the projects within the ecosystem.

    Impact

    • Improve Project Visibility: By providing detailed analytics and visualizations for DOT projects, PolkaFlow can help increase the visibility of these projects, making it easier for developers and users to find and contribute to them.

    • Enhance Developer Productivity: With the ability to quickly access important data and metrics, developers can more easily identify areas of the project that need attention. This can lead to faster issue resolution and more efficient development cycles.

    • Encourage Community Engagement: By providing a centralized location for viewing project activity and contributions, PolkaFlow can encourage community engagement and collaboration. Users can easily identify areas where they can contribute to the project and engage with other developers and users.

    • See Ecosystem Evolution: PolkaFlow can help show the evolution of DOT projects over time by providing historical data and visualizations of key metrics, enabling developers to better understand the project's development trajectory and identify areas where protocol gains trends.

    • Stands Out: Currently, there is no project that provides a comprehensive analytics dashboard for open-source projects in the DOT ecosystem. PolkaFlow fills this gap and provides value by enabling developers and stakeholders to easily gain insights into the activity and performance of DOT projects.

    Project Detailsโ€‹

    We've prepared two demo videos 1 and 2, showcasing how Polkadot.js Apps an Staking dashboard are seamlessly connected with MetaMask using the Polkagate Signer Snap. This Snap flawlessly signs transactions, enhancing the user experience.

    Our project primarily utilizes JavaScript and TypeScript for development, ensuring accessibility and extendability for developers interested in contributing fresh ideas.

    While not a full-fledged extension like existing Polkadot ecosystem extensions such as Polkagate, Subwallet, or Talisman, our project has the potential to evolve into a comprehensive extension. This transformation is contingent on MetaMask expanding the capabilities of its Snaps, which some of them are currently accessible only to developers using MetaMask Flask.

    To uphold Snap security, MetaMask requires audits from selected teams. We are in the process of arranging these audits to ensure a high level of security. Additionally, we have plans to further enhance the extension's capabilities as soon as MetaMask provides Snaps with more functionalities.

    Ecosystem Fitโ€‹

    Where and how does your project fit into the ecosystem?

    Polkamask is designed to seamlessly integrate into the Polkadot and Kusama ecosystems by enhancing the interaction between MetaMask and Substrate-based chains. It introduces the Polkagate Signer Snap, allowing users to access and utilize the Polkadot and Kusama networks without any code modifications. It aims to bridge the gap between MetaMask and the Polkadot ecosystem, making it more accessible and user-friendly.

    Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    Our primary target audience includes dApp developers and users who engage with the Polkadot and Kusama ecosystems through MetaMask. We aim to provide a solution that benefits developers by simplifying the integration process and offers users a smooth experience when interacting with Polkadot and Kusama dApps through MetaMask.

    What need(s) does your project meet?

    Polkamask addresses the need for seamless integration between MetaMask and Substrate-based chains like Polkadot and Kusama. It removes barriers and complexities in the user experience, allowing MetaMask users to access these ecosystems without having to modify existing dApps. This simplification and user-friendliness are essential for the broader adoption of Web3 technologies.

    Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    There are existing projects in the Polkadot ecosystem that aim to enhance the user experience and accessibility. One example is the Polkadot wallet Snap developed by ChainSafe. However, it primarily supports Polkadot, Kusama, and Westend based on their codebase on GitHub. An important distinction is that integrating with this wallet Snap often requires dApps to undergo modifications to utilize the Snap, which can be a significant barrier to integration.

    In contrast, Polkamask differentiates itself by introducing the Polkagate Signer Snap. This Snap offers seamless integration with MetaMask, providing a user-friendly experience and eliminating the need for dApps to make code modifications. This ease of use and the ability to connect to Substrate-based chains without requiring code changes make Polkamask a unique and valuable addition to the ecosystem.

    Additional Information โž•โ€‹

    Storage: When a user creates a Smart Record Contract, she will be asked for the music file as well as the album cover. These files are saved on a centralized storage at the moment as anybody can download the files from ipfs with no benefit to the artist. Artist can individually choose the SSPs she would like to distribute the songs to, or can upload with them directly, and refer to the SRC Address for royalty payment purposes. In the future, we will implement decentralized file storage through IPFS with Access Control List, a permissioned version of IPFS where access is controlled by programmable smart contracts that contain an Access Control List (ACL). The modified ipfs client will serve files to the requestor only if the permission is approved in the ACL. This offers transparent, public and verifiable access without a central controller. Control is always in the hands of the data owner, the smart contract author. Every SSP will be required to run a ACL-IPFS node of their own.

    It must be noted that the above mentioned file storage mechanisms are based on high latency storage solutions and is for data transfer between the artist and the SSPs. The SSPs will have to maintain a local cache in order to serve files to the end user.

    Traditional Performing Rights Organizations: Every country has multiple local performing rights organizations who are running inefficient softwares with very high licensing costs. Such PROs can use a SSP Smart Contract instance to calculate royalties and send payments on the blockchain using currency of their choice.

    No. This is currently a self-funded project.

    We have attracted 3 open-source developers. Apart from this, we are well connected in the music industry and we have 100+ artists willing to upload their songs.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Implement, release and maintain a snapshot website for Polkadot and Kusama.

    Project Detailsโ€‹

    Substrate has an --export-chain and --import-chain feature to allow node operators to sync faster.

    This is a key feature to be able to recover quickly in case of node failure. This results in decreased downtime, which is beneficial for the ecosystem.

    This work will consist of an open source project, and a production website.

    polkadot-snapshot-generatorโ€‹

    The open-source project, polkadot-snapshot-generator, will consist of:

    • infrastructure code for running a Polkadot node (or Kusama, or any substrate node) on Kubernetes on a cloud platform, deployed with Terraform
    • code to take filesystem-level snapshot of a live chain, then run export-chain command
    • mechanism to upload the snapshot to a storage bucket and publish a website with the most recent snapshot
    • a master cronjob, the snapshot engine, that triggers snapshot creation on a schedule

    There will be 2 kind of generated snapshots: RocksDB and Parity DB, until RocksDB becomes deprecated.

    polkashots.ioโ€‹

    We will also deploy and maintain https://polkashots.io, a website hosted on Cloud Infrastructure which will make snapshots available for free for community members.

    The snapshot generation frequency will be configurable. 24 hours frequency seems reasonable. Nodes typically sync very fast from a 24 hour lag.

    Snapshots will be stored on a public Google cloud storage bucket. We will be providing Polkadot and Kusama snapshots.

    The snapshots will be clearly identified by block height and block hash. Hyperlinks will be provided to the main indexing websites (Polkascan, Polkastats) so the user can verify that the snapshot they are downloading is indeed the legitimate Polkadot chain.

    Additionally, the snapshots will be hashed and a signature will be published on the polkashots.io website.

    There will be static links (such as https://polkashots.io/dot/rocksdb) that always point to a recent snapshot, which should simplify setup of an automated recovery mechanism.

    We will modify our own existing projects, polkadot-k8s and polkadot-k8s-aux. We will configure the default behaviour when spinning up a new chain to download snapshots automatically from the polkashots website.

    Ecosystem Fitโ€‹

    To my knowledge, there is no other active snapshot website for Polkadot/Kusama.

    This page appears to be no longer updated.

    People on Riot Validator Lounges regularly ask for fresh snapshots.

    5.Live websiteDeploy polkashots.io with recently updated snapshots

    The open-source project will have three directories, terraform, k8s and docker. Their contents are described below.

    Terraformโ€‹

    The terraform module takes parameters such as chain_name, billing_account... as input, and uses the Terraform GCP provider. It creates a Google Cloud Project and a Kubernetes cluster.

    Inside the cluster, it deploys a configurable number of Kubernetes namespaces as described below.

    It also configures Google Cloud Build to automatically build the containers needed to run the snapshotting jobs, and push them to the cluster.

    The entire setup can be destroyed with terraform destroy.

    Kubernetesโ€‹

    A Kubernetes Deployment runs a Polkadot or Kusama node in a Pod with a Persistent Volume for storage.

    This node can optionally be brought up from a snapshot itself (in case the snapshot engine itself needs to be recreated).

    It is not possible to do export-chain on a running node, therefore it is necessary to leverage some cloud filesystem snapshotting capabilities.

    A Kubernetes Cron Job triggers a pod with special privileges that in turns triggers the following Kubernetes actions:

    • take a Persistent Volume Snapshot of the Polkadot node storage
    • create a persistent volume from the snapshot
    • triggers a Kubernetes job called "snapshotter" which:
      • mounts the persistent volume created from snapshot
      • runs the export-chain command against it
      • compresses, hashes the snapshot, then uploads it to a bucket
      • builds a Jekyll static website from source and pushes it to Firebase, with relevant metadata of the generated snapshot
    • tears down all objects created above

    Dockerโ€‹

    A series of custom-build containers built for performing the actions described in the previous section, namely:

    • snapshot-importer: imports a snapshot when initially kicking off the setup
    • snapshot-engine: the job that sends kubernetes control plane commands to generate a filesystem-level snapshot
    • snapshotter: the job that performs export-chain and pushes it to a bucket
    • website-builder: the job that builds the Jekyll static site

    The Dockerfiles and associated scripts to build the containers listed above will be shipped as part of the project.

    Community engagementโ€‹

    We will be announcing the website and the project on Medium.

    Future Plansโ€‹

    We may be extending offers to various Substrate chains to have their snapshots hosted on our platform.

    Project Overview ๐Ÿ“„โ€‹

    Where did the idea come from?โ€‹

    Inspired by the success of STEPN, we have great confidence in Web3 applications combined with life scenarios. Because to let the majority of users enter the Web3 world, the interactive way of life scenes is the easiest entry. So we started from the fitness field and developed a Web3 smart fitness application, allowing ordinary users to pick up fitness equipment, training daily + GameFi, and gradually understand how the Web3 world can bring them more value and fun.

    Although STEPN achieved great success and dazzling attention as soon as it was launched, it also exposed the following problems:

    1. Getting started is difficult and high risk. Beginners first need cryptocurrency and buy at least one virtual sneaker before they can start running. Due to the long-term price instability of cryptocurrencies, users cannot grasp the timing of buying cryptocurrencies, which can lead to serious losses.
    2. Insufficient decentralization. STEPN, like most GameFi, adopts the solution of decentralization of asset transactions and centralized gameplay. This is because due to the bottleneck of the current smart contract technology, it is impossible to achieve complete decentralization, so the game system has the risk of self-theft, such as inflated rewards, malicious bans, and service suspension.
    3. Incentives are not sustainable. The incentive tokens generated by STEPN running are freely circulated without restrictions, and the business model is unsustainable, and will eventually enter a death spiral.
    4. Is really cross-chain?. Although STEPN publishes the same kind of assets on both public chains, the asset values are different, and it is not a cross-chain in the true sense.

    After noticing the above problems, we finally adopted Substrate as the underlying technology in technology selection, and developed a blockchain named Polket. The goal of Polket is to create more commercial application scenarios for NFTs and connect to the Polkadot/Kusama network in a parachain manner. Based on the Polket chain, we will develop a smart fitness-type Web3 application to achieve capabilities that STEPN cannot achieve. We will name it ToEarnFun.

    Overviewโ€‹

    logo

    ToEarnFun is a fit to earn Web3 smart fitness application. Compared with other x-to-earn applications that only have SocialFi and GameFi elements, it can be connected with real smart fitness equipment. It relies on the encryption technology of the hardware chip to ensure that the sweat is paid fairly. The entry-level users of ToEarnFun do not need to purchase cryptocurrencies, but only need to purchase smart fitness equipment adapted to the application, and they can fit to earn immediately, greatly reducing the difficulty for ordinary users to enter the web3 world.

    Project Featuresโ€‹

    Easy To Useโ€‹

    After the fitness equipment producer has passed the official qualification certification of ToEarnFun, the producer will register the chip public-key on the blockchain for each piece of fitness equipment produced. The user purchases ToEarnFun fitness equipment in the store, and completes the activation in the App, then can get a VFE (Virtual Fitness Equipment, it can be understood as a type of NFT). Users train through fitness equipment every day, and the system calculates the corresponding rewards based on the VFE attribute value on the chain.

    Compared with STEPN, which requires users to use cryptocurrencies to purchase Sneaker, ToEarnFun does not require users to own cryptocurrencies, and it is easier to meet regional compliance requirements in terms of sales methods. The ToEarnFun community is formed by a group of users with real fitness needs, and is also a group that is optimistic about the future of Web3. Opens a door for Web2 users to enter the Polkadot ecosystem.

    Equipment Chip Embedding Proof Of Trainingโ€‹

    How to prove that the player has completed the training?

    In order to realize the Proof Of Training algorithm, we need to embed a crypto algorithm in the chip of the smart fitness equipment. The equipment needs to generate a key pair and register the public key on the blockchain before leaving the factory. After the user activates the equipment, each time he completes the training, the equipment will sign the training data and submit it to the blockchain to complete the proof, and finally the user will receive a fair reward.

    Since the private key of the equipment is generated by the chip before leaving the factory, the player cannot obtain it and cannot tamper with it, which prevents the player from modifying the training data through software, but the player can still cheat through physical plug-ins. However, with the development of technology, we will add motion sensors and biological inspection technology to the equipment to record more valuable data for player training and to prevent cheating by physical plug-ins.

    Fitness + GameFiโ€‹

    ToEarnFun not only has the advantages of smart fitness applications, but also realizes the gameplay of GameFi. The core of the game is VFE(Virtual Fitness Equipment) as the gameplay, VFE has a level system, with four basic attributes (efficiency, skill, luck, durability), four rarities (common, elite, rare, epic), and available power. When the user activates the equipment, they will get a VFE of common rarity and level 0 for free. Users can earn FUN by consuming energy through daily train, FUN is a consumable in VFE gameplay, used to: upgrade VFE level, VFE charging, Synthesize VFE, transaction fees, challenge events and more. VFE Get attribute points for each level up, and users can configure attributes independently. At present, the equipment we are implementing to interact with VFE is smart jump rope.

    VFE is shorthand for Virtual Fitness Equipment. It can be understood as a subclass of NFT (non-fungible token). We will create VFE such as Smart Jump Rope, Smart Hula Hoop, Smart Boxing, Spinning Bike on the chain. What the user gets is a unique VFE instance minted by VFE.

    Basic attribute description:

    • Efficiency: It affects the amount of FUN income. The higher the efficiency, the more stable the income growth. It is recommended for entry-level users to configure.
    • Skill: Affects the training score factor. The higher the skill, the higher the FUN income from training score conversion. Training score can dramatically increase or decrease your income, so recommended configuration for advanced users.
    • Luck: Affects the drop probability of items and the amount of income added by random numbers on the chain.
    • Durability: Affects VFE charging cost.

    Rarity Description:

    • Normal: Free with purchase of fitness equipment.
    • Elite: Collect VFE parts and combine with VFE chips to mint a new VFE, with a small probability to obtain.
    • Rare: ToEarnFun Official regular sales.
    • Epic: Participate in the ToEarnFun official event to get it.

    Base stats and upgrade points, common < elite < rare < epic.

    The gameplay is completely decentralizedโ€‹

    Most GameFi applications are implemented with asset transaction decentralization and gameplay centralized solutions. Because most Dapps are implemented based on smart contracts, limited by the execution efficiency and upgrade difficulties of smart contracts, it is difficult to achieve decentralized gameplay. Thanks to the forkless upgrade feature of Substrate, we can implement the gameplay on the chain, and more new gameplay can be implemented through the Runtime upgrade in the future, which will be a Web3 application in the true sense.

    Project Application Scenariosโ€‹

    Combination of Physical Industry and Blockchainโ€‹

    production

    Participants: Fitness Users, Equipment Producer, ToEarnFun Official.

    1. ToEarnFun Official first needs to create a VFE class on-chain. The first thing we implement is the VFE of the rope skipping.
    2. To cooperate with ToEarnFun, equipment producers need to complete qualification certification and deposit a certain amount of security deposit into the Producer Ledger on the chain, which will be used to deduct fees for subsequent minting of VFE instances.
    3. According to the deposit amount deposited by the equipment producer, the system grants the producer a certain number of VFE minting rights.
    4. After the equipment producer completes the qualification certification, the toearnfun-crypto-sdk is integrated into the fitness equipment chip to realize the encryption protocol.
    5. Before leaving the factory, fitness equipment needs to be registered on the Equipment Ledger, and a mintinng fee will be reserved from the Producer Ledger on-chain.
    6. Fitness users can buy ToEarnFun cooperative fitness equipment in the local store without cryptocurrency.
    7. Fitness users complete on-chain activation of fitness equipment through the ToEarnFun app.
    8. After the fitness equipment is successfully activated, Producer Ledger will pay a minting fee from the reserved balance to ToEarnFun Official Treasury.
    9. Because the producer has the minting right of the VFE class, a VFE instance will be minted on-chain to fitness users.
    10. Fitness users can get a VFE instance for free, in fact, the producer paid the minting fee when registering the equipment on the chain.

    This business model not only helps traditional fitness equipment producers enter the Web3 world, expands the user base, and promotes industrial development, but also brings stable income to ToEarnFun and motivates FUN on GameFi in the future. Modules provide the foundation.

    Fitness + GameFiโ€‹

    Fitness+GameFi

    Participants: Fitness Users, ToEarnFun Official.

    1. Fitness users use fitness equipment for daily training.
    2. The fitness equipment signature training data will be reported to the on-chain Training Ledger through the App.
    3. Calculate the reward according to the VFE attribute bound to the fitness equipment and the number of energy consumed during the training.
    4. The FUN incentive module issues rewards to fitness users, but there is a daily upper limit on rewards.
    5. Fitness users can use FUN to level up VFE instances to increase attribute points.
    6. Fitness users can sell their excess FUN to the FUN Buybck Pool.
    7. ToEarnFun official regularly buyback FUN in the pool.
    8. After each buyback of FUN, its buyback price will change. In order to ensure price stability, changes in the FUN Buyback Price will affect its inflation rate.

    This business model not only allows users who like fitness to get the equivalent of their sweat, but also allows users who are addicted to GameFi to have the goal of fitness.

    VFE Marketโ€‹

    VFE Market

    Participants: Fitness Users, ToEarnFun Official, 3rd-party IP.

    1. ToEarnFun Official can approve 3rd-party IP certain amount of VFE minting rights.
    2. Whether it is ToEarnFun Official or 3rd-party IP, as long as you have VFE minting rights, you can mint new VFE instances.
    3. However, every time a VFE instance is minted by a 3rd-party IP, the minting fee needs to be paid to ToEarnFun Official.
    4. The newly minted VFE instance will be put into the VFE market and will be sold by auction or fixed-price.
    5. Fitness users can consume FUN to unbind the VFE instance on the equipment.
    6. The unbound VFE instance can be sold to the VFE market.
    7. Fitness users can also buy their favorite VFE instances in the VFE market.
    8. Fitness users buy VFE instances with better attributes, and then bind them to the equipment for training, which is the most effective way to earn FUN.

    Compared with traditional games, GameFi has the characteristics of playability and possession, and game items have value. ToEarnFun Official can bring income through the sale of VFE, or it can also approve 3rd-party IP to mint VFE to bring income. Fitness users can also freely exchange VFE in the market to achieve arbitrage.

    Competition Challengeโ€‹

    Competition challenge

    Participants: Fitness Users, ToEarnFun Official, Public Welfare Organizations.

    1. ToEarnFun Official create competition template, set: registration fee, registration requirements, competition requirements, scoring rules, bonus distribution, cycle time limit, etc.
    2. The competition template will publish event instances periodically.
    3. Fitness users who meet the registration requirements can pay the registration fee to participate in the event.
    4. Fitness users use their own fitness equipment to challenge according to the requirements of the competition.
    5. The fitness equipment reports the training data to the on-chain competition record.
    6. After the game, the game record will be determined according to the scoring rules of the game.
    7. Prizes will be awarded to the winner of the competition.
    8. A portion of the funds raised by the event will be invested in the Public Welfare Treasury.
    9. The funds of the Public Welfare Treasury can be donated to public welfare organizations through the proposal of the Public Welfare Council.

    The use of blockchain to realize competition events is a very suitable application scenario. It not only makes the competition fair, open and transparent, but also greatly reduces labor costs and allows the Public Welfare Treasury to obtain more funds. At the same time, DAO is used to manage the Public Welfare Treasury, which ensures the sustainable development of public welfare undertakings.

    Ecosystem Fitโ€‹

    Where and how does your project fit into the ecosystem?โ€‹

    As we all know, it is more complicated for ordinary users to enter Web3. They need to buy cryptocurrencies and learn to use cryptocurrency wallets. Learn about different ecosystems and find out which Dapps are right for them.

    I try to simplify this entry through the combination of hardware + Substrate + Mobile App. Let ordinary people only need to buy a smart jump rope at the retailer, and training everyday, Web3 will give them another income. Gradually, they will learn about the Polkadot ecosystem, and they will slowly discover that Polkadot's parachains can bring them more value.

    Who is your target audience?โ€‹

    Our target audience are fitness enthusiasts and Polkadot ecosystem's users.

    What need(s) does your project meet?โ€‹

    • Use token incentives to promote people's daily training and get healthy body.
    • Through physical product sales, new users will be brought to the Polkadot ecosystem.

    Pontem Network (VM).

    • Team Name: Dfinance (Wings Stiftung).
    • Payment Address: 32AAAxmKJ9XxCsGSwt11oAuovCUHbgsgfY.

    Project Overviewโ€‹

    Overviewโ€‹

    Pontem Network aims to bring the Move VM and Move language, and ecosystem around it to Polkadot.

    The Move language and the Move Virtual Machine, both developed by Facebook Libra, are among the safest technologies out there that enable the creation of smart contracts. While having built-in security by design such as resource-oriented architecture and formal verification, Move VM still severely lacks toolsets and documentation.

    We are going to create the Move pallet to make it possible for developers to publish their Move VM modules and execute scripts, also, we already built a rich toolset and documentation for Move language, so we will need only adopt it for Polkadot.

    This is where our team has a unique experience, due to over 2 years spent working with Move and building tools around it. We have been working closely with Libra (as recognized technical adopters) as part of the Dfinance project which is utilizing the Move language and Move VM in order to run safe and usable smart contracts.

    Project Detailsโ€‹

    Implementation of Move VM pallet won't be an easy task, even taking into account our experience connecting Move VM with Cosmos SDK, achieved via integrating Move VM as GRPC service.

    In the case of Polkadot WASM Runtime we canโ€™t repeat the same approach with GRPC due to limitations of Runtime, but we can do a more elegant solution by utilizing Move VM inside Runtime. To be clear letโ€™s see our plan step by step.

    1. Move VM and language written in Rust language and can be compiled to WASM, unfortunately we canโ€™t use crates that depend on runtime. We will create a stable working pallet by forking of Move VM/language and replace creates with ones we can use.
    2. We will make Move VM outputs (writesets) compatible with Polkadot key-value storage, as during our latest research we discovered itโ€™s not going to work โ€œout of the boxโ€ and will require some time to build a solution. Same with address format SS58, and non VM balances.
    3. We need to make gas usage of Move VM compatible with Polkadot standards. At least by using the same units like other VMs/pallets using.
    4. Build a documentation around the Move pallet, adopt existing tools and docs about VM and language.

    We already have rich experience in these topics because of our current Dfinance project, so far we developed:

    Ecosystem Fitโ€‹

    • Developers can be interested to build their DApps on Polkadot using Move technology stack, as itโ€™s a safe and useful language which is getting more and more adoption.
    • Libra is developing and using Move, so Polkadot will have at least initial compatibility with Libra at least by allowing using the same modules in both networks.
    • Flow - Crypto Kitties creators blockchain also going to utilize Move VM and language, also by creating new language on top of it - Cadence, which can be adopted to Polkadot later.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Project 1001 is a combination of wordToWorld and Uniwrap, and is also an experiment with NFTs and DeFi. It creates a very interesting game for users to play. It transforms spoken words into dynamic NFT stories in real-time using speech recognition and natural language processing. Users can generate stories with NFT models, the generated story is an NFT / a group of NFTs. A user who has the story could bid to exhibit it on a piece of land to the whole world.

    Project 1001 as a part of Substrate / Kusama / Web 3 Ecosystem

    Project Detailsโ€‹

    Featuresโ€‹

    • Speech interactive: let a bird fly just by saying "The bird is flying!", 1001 visualize a dynamic world according to users' spoken words.
    • Composable NFT story: NFTs from different networks could be integrated together into one story, the story itself as grouped NFTs could be used in multiple DeFi cases like lending, staking, or as an IDO permission.
    • DIY unique characters: Make your own characters by composing different body parts, see them come to life right away in your story.
    • Rentable land for stories: There are various lands for renting and telling stories. Users can bid for exhibiting their story for the land, and the story will be recorded in "world history".

    Token Usagesโ€‹

    In the game, the system token is used in all the cases involved with the economy, specifically:

    • A story could be minted as an NFT on different lands with system token.
    • The story elements like Action, Emoji, Sounds could be exchanged as NFT on the marketplace.
    • A story on different lands outputs different stories, and the land could be bought or rented with system token, so that a story could be displayed on the land.
    • Our model editor enables users to easily create models in 1001 and models could be minted as an NFT with system token as fee.

    Here is the flow of the token economics with KSM as the system token for example.

    Ecosystem Fitโ€‹

    According to our research, we are the first project to build an NFT game on Substrate, and we hope to create a new era of NFT+DeFi.

    The 1001 project could make NFTs more interactive, add exposure, and enable NFT creation just by speaking by non-tech and non-art users, the created NFT could be further used in the internal DeFi scenarios, so it could greatly extend the NFT usability on Polkadot/Kusama.

    Project Overview ๐Ÿ“„โ€‹

    If this application in response to an RFP then please indicate this on the first line of this section.

    Overviewโ€‹

    Backgroundโ€‹

    It is clear to us that building a better, faster and cheaper Ethereum is not nearly enough. Just like Ethereum can do things Bitcoin can never do and subsequently inspired many new innovations, Substrate and Polkadot are categorically different from Ethereum that will empower many new types of innovations outside of the sandbox.

    On a domain-specific chain like the Acala chain, there're many domain specific runtime optimizations. For example, thereโ€™re DeFi primitives, liquidity and users that can be tapped into, there are also innovations that are simply not possible on Ethereum - customizable economic policy, for example Acalaโ€™s Flex-Fee allows users to pay transaction fee with any supported tokens; native cross-chain capability; on-chain governance apparatus (no more locked funds); full upgradability (no more contract migrations) and more.

    Weโ€™d love to have all of these and EVM compatibility.

    Current Solutionโ€‹

    Current solution i.e. Frontier in principle is to emulate the Ethereum node experience. It aims to implement the full set of Ethereum RPC and emulates Ethereum block production process. This allows existing Ethereum tools such as Metamask and Remix to work with a Frontier enabled node seamlessly.

    Integrating Frontier have revealed the following challenges by their severity:

    1. Confined inside the EVM Sandbox (High): users will need to use a Substrate wallet (e.g. Polkadot-js Extension) and Metamask at the same time if they ever want to taste the real power of Acala, Substrate or Polkadot for that matter. This is certainly a deal-breaker for us.
    2. Making Nodes more Expensive (Medium-High): Substrate does not store transactions by hash nor historical events, nor does it provide any event filtering ability. Frontier injects special block importing logic, storing the transactions and events into an off-chain auxiliary store in order to power the query API required by Ethereum. This kind of goes against the goal to have a lightweight node to lower barriers for people from anywhere to run nodes which helps the network to be more decentralized.

    Our solution - Project Bodhi: Composable & Innovative Stack for EVM on Substrateโ€‹

    solution

    Project Bodhi offers these benefits

    1. Full-stack composability: expose pallets API as EVM precompiled contracts
    2. Single-wallet experience: emulate full Ethereum JS SDK client (bodhi.js)
    3. Lightweight while Queryable: Substrate node + Indexer node
    4. Iterate fast with Typescript
    5. Revamped EVM economics

    This solution can be very useful for any domain-specific chains that want to offer the full experience of runtime and Smart Contract.

    Project Detailsโ€‹

    We expect the teams to already have a solid idea about the project's expected final state.

    Therefore, we ask the teams to submit (where relevant):

    • Mockups/designs of any UI components
    • API specifications of the core functionality
    • An overview of the technology stack to be used
    • Documentation of core components, protocols, architecture etc. to be deployed
    • PoC/MVP or other relevant prior work or research on the topic

    Details documentations of the projectโ€‹

    • Project overview PPT here
    • Project brief & plan here

    PoCโ€‹

    We have completed a proof-of-concept to verify feasibility of the project here

    Technology Stackโ€‹

    • The SDK (bodhi.js): this will be a new provider SDK which gets injected into existing web3.js, and wraps around polkadot-js to do Ethereum and Substrate translations (transactions, RPC calls, weights to gas etc.). Written in Typescript.
    • The Substrate Node: implement additional RPC to interact with EVM
    • The Indexer server: integrate it with bodhi.js, EVM event logging etc. Current implementation here which both Laminar and Acala testnets have been using.

    Scopeโ€‹

    There are a lot of work involved to get all of these into a product-ready state, which is what we always aiming for, but it'd be too big to fit into one single open grant. Therefore we have carved out a scope specifically for this grant, followed by details for future work.

    Grant Scope: Project Bodhi MVP The MVP scope involves

    • building all necessary components for ERC20 playground
    • integrate with an existing Ethereum project that is reasonably sophisticated and requires us to build address mapping between Substrate & EVM addresses
    • integrate with one existing Ethereum deployment tool e.g. Waffle

    Future development

    1. Expose orml-currencies precompiles to EVM
    2. Expose orml-nft precompiles to EVM
    3. Implement and integrate with Indexer Node
    4. Integrate fully with Polkadot Extension
    5. EVM economics: state renting, contract existential deposit, contract deployment economics
    6. Replace Gas system with Weights system

    Ecosystem Fitโ€‹

    Nope, if so we'd be more than happy to leverage it than build it ourselves.

    Future Plansโ€‹

    Our vision is to provide a composable and innovative stack for EVM on Substrate. We've seen the power of composibility in DeFi on Ethereum, and it's not limited to one domain. Meanwhile we also want to break-free from Ethereum constraints, and offer innovative economic models, fight scams, and improve usability. We're determined to make this next level unified experience happen on Substrate, through the the Project Bodhi stack. We are going to eat our own dog food to use it for Acala. And we believe it will be useful for most domain-specific parachains/parathreads who have custom runtime and also want to leverage smart contracts.

    Silent Data Polkadot Integration

    Project Overview ๐Ÿ“„โ€‹

    This application is in response to an RFP

    Overviewโ€‹

    Applied Blockchain has developed Silent Data as a platform for proving properties of private off-chain (web2) data in blockchain smart contract (web3) applications (dApps).

    Silent Data leverages hardware secure enclaves with attestation, in particular, Intel SGX in order to enable privacy-preserving retrieval and processing of off-chain data, and generation of cryptographic proofs that are verifiable in blockchain smart contracts. This ensures that sensitive information is never revealed, not even to those hosting the platform, and code attestation with a smart contract link ensures that the code used to retrieve the data and generate the proofs cannot be modified or interfered with by the operator.

    Silent Data proof certificates are powerful because they can verifiably demonstrate that private data meets certain requirements without the need to reveal that data, and without that data being accessible to Silent Data operators. The service is initially centrally hosted, and will be decentralised over time in order so that it cannot be censored by the operator. One of the properties of SGX is that it is possible to prove what code is being run inside a particular enclave. This means that we would be able to provide decentralised "nodes" with prebuilt enclaves that contain the code required to run the Silent Data service and then provision them with encrypted secret keys so that they can create compatible proof certificates. Once provisioned, these nodes would be able to run in a decentralised fashion, independent from the original operator.

    Silent Data enables verification of web2 account ownership, including social media services such as Instagram. This enables enrichment of web3 identities and assets with attestations from the web2 world, for example, if someone is using web3 to purchase from a brand with a web2 presence.

    NFT creators with verified Instagram accounts, for example, can use Silent Data to prove they are behind a specific wallet. This will help to reduce fraud in NFT and web3 commerce.

    Silent Data will also be extended to enable verification of web2 financial credentials, to augment web3 DeFi and tokenisation dapps.

    An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama.

    Silent Data provides privacy-preserving cryptographic proofs about properties of web2 data. We refer to the output as a โ€œproof certificateโ€, consisting of a set of key-value pairs signed by a manufacturer attested hardware secure enclave. The signatures can be verified using various cryptography primitives available on different blockchains, including Polkadot (Substrate) and Ethereum. A blockchain wallet is associated with a Silent Data proof certificate by having the wallet owner sign the private data that is encrypted and sent to the enclave with their wallet private key.

    Silent Data will integrate with a Substrate chain to provide maximum coverage within the Polkadot ecosystem.

    Integrating and enabling Silent Data in Polkadot parachains will help to bring additional functionality and security to Polkadot dapps that have some reliance or interaction with the web2 world and web2 accounts.

    Pokadot will benefit through enabling identifies to be further verified where necessary using cryptographically verifiable proofs of web2 accounts (social media, such as Instagram, or otherwise), enabling the DeFi ecosystem to grow more securely beyond native on chain assets to those assets whose origin, provenance and/or price are anchored in web2 accounts (through additional integrations with other web2 accounts). Polkadot DeFi investors will benefit from increased cryptographic verifiability when backing off chain and real world assets.

    An indication of why your team is interested in creating this project.

    Applied Blockchain was founded by Adi Ben-Ari, in London in 2015 when the Ethereum code base was first released, and he spent the early months with some members of what became the Parity team exploring and understanding the platform. Since then Applied Blockchain has closely followed developments at Parity and Polkadot (including some minor collaborations along the way), and is particularly interested in bringing the Silent Data technology to Polkadot parachains and dapps.

    Polkadot parachains already offer a broad range of dapps and functions, and coupling the strong security fundamentals of Substrate with those of Silent Data will create compelling additional optionality for Polkadot dapp developers.

    Project Detailsโ€‹

    September 2022

    • Data models / API specifications of the core functionality
    • September 2022
    • An overview of the technology stack to be used

    Silent Data includes a public facing web application and API that facilitate communication with a secure enclave. DApps can request an individual to securely transfer their data to the enclave for verification. Generally, the subject of a check will provide access to their data to the enclave via an OAuth flow which generates credentials that can be used to fetch data from APIs on behalf of the subject. These credentials are encrypted and sent to the enclave along with a signature of the private data used to verify ownership of a blockchain wallet.

    The enclave decrypts the credentials and uses them to retrieve data from trusted data sources over HTTPS (initially Instagram). The enclave will then perform the preconfigured calculations and checks on the data in order to verify that the input query is true or false. The wallet signature and decrypted credentials are also used to prove that the owner of the wallet had access to those credentials and is most likely the owner of the data.

    The enclave can optionally associate and attest to non-private data relating to the check (e.g. Instagram account name) by including it in the proof certificate data as key-value pairs. The proof certificate includes some standard information such as an identifier of the check performed, the wallet address of the user, a timestamp, and the identifier of the proof certificate on Silent Data, along with any extra non-private data. The enclave will then sign this certificate using an algorithm compatible with the target blockchain and send it to the the dApp smart contract for persistence and verification.

    Substrate dApp smart contracts will initiate the Silent Data proof of Instagram account ownership check. The smart contracts will receive the proof certificate from the Silent Data enclave, and verify the attestations, proving that the owner of the wallet is the owner of an Instagram account, but proving they have direct access to login to the web2 account.

    Ecosystem Fitโ€‹

    We believe that as part of the evolution of web3, web2 and web3 will converge before diverging. This will enable users to leverage their identities and assets, currently anchored in web2 to the web3 world. In order for this to occur, web3 DApps, including those deployed in many of the Polkadot parachains, need a way to securely and safely verify off-chain web2 data.

    Regular web2 API integrations require trust in additional third parties, as data can be compromised, viewed and manipulated. Standard blockchain oracles reveal sensitive web2 data to validators. With Silent Data, DApps can now fully verify web2 data properties, without any data being revealed.

    There are already numerous parachains deployed in the Polkadot ecosystem, primarily focussed on DeFi, NFTs, identity and tokenisation services. Many of those parachains and dApps can benefit from integrating with Silent Data to verify web2 credentials, including Instagram account ownership to provide proofs that can then be leveraged by the parachain dApps (for example to augment the identify of a seller wallet) without the need to share any user data during the verification process and without storing the user data in the parachain. Silent Data will also be extended to enable verification of web2 financial credentials, to augment web3 DeFi and tokenisation dapps.

    • What need(s) does your project meet?

    The project enables smooth and user-friendly proof of web2 account ownership and credentials in web3 dApps. This can be used to reduce fraud, but augmenting web3 wallet identities and assets with verified web2 account data (e.g. Instagram account ownership), without revealing sensitive account data and credentials to any third parties or platform operators..

    Silent Data can be used to verify web2 account ownership, such as social media accounts ownership such as Instagram, for example, to provide proofs that can be used inside the web3 environment. The solution guarantees complete confidentiality and that no user data is visible during the verification process, not even to the platform operator, nor is it persisted anywhere outside the web2 platform.

    NFT creators with verified Instagram accounts, for example, can prove they are behind an NFT and prove their wallet owns a certain verified Instagram account. With this they can avoid it being impersonated or having fake assets being associated with their identity by providing cryptographic proof of Instagram account ownership and associating this with their wallet and minted NFT.

    Future implementations will apply not only to Instagram and NFTโ€™s, but also to other identity and asset credentials useful in DeFi.

    0e.ArticleWe will publish an article/workshop that explains what was done/achieved in the extension and deployment of Silent Data confidential computing oracle.
    1.ExtensionWe will extend the Silent Data confidential computing oracle to generate proofs verifiable by ink! smart contracts by adding support for the sr25519 signature scheme and the polkadot{.js} wallet extension.
    2.LibraryWe will develop a JavaScript/TypeScript library to enable Node.JS backends to interact with the Silent Data API. The library will allow DApp creators to generate new proof certificate requests and fetch the results of checks.
    3.Smart ContractWe will develop an example ink! smart contract for verifying Silent Data proof certificates and extracting the verified proof data. The smart contract will take a signed certificate and signature as input verify either an sr25519 or ed25519 signature with a fixed enclave public key stored in the contract. The contract will then parse the CBOR encoded certificate data to extract the verified key-value pairs and optionally store them on chain. We will deploy the smart contract to a Polkadot testnet and provide an example DApp to demonstrate the flow of generating Instagram account verification certificates with Silent Data and verifying them in a smart contract.

    Future Plansโ€‹

    • Integration with other web2 social media platforms (Twitter, Google authentication, etc.).
    • Integration with other identity and asset related web2 data sources (open banking, identity and AML checks).
    • The team's long-term plan is to become the platform for providing properties of private web2 data for consumption by web3 applications.

    6 Future Plansโ€‹

    The Prosopo captcha service will be deployed to a Substrate chain (chain to be confirmed) that implements pallet-contracts. This will be the initial version of the service and will help us refine before deploying on additional chains. Initially, Provider registrations will be invite only and will be opened up once the service is deemed to be properly functioning.

    6.1 Enhancementsโ€‹

    6.1.1 Captcha Service SDKโ€‹

    The following features will be added to the Captcha Service SDK:

    6.1.1.1 Multilingual supportโ€‹

    Initially, captchas will either be language-independent or English based. This will be expanded to cover as many languages as possible.

    6.1.1.2 Database supportโ€‹

    Captchas will initially need to be stored in a database on the Providers server. This feature will be improved to accept multiple different types of database and also distributed storage, such as IPFS.

    6.1.2 Prosopo Smart Contractโ€‹

    The following features will be added to the Prosopo smart contract:

    6.1.2.1 Difficulty Levelsโ€‹

    It will be possible for Dapp Operators to request captchas of different difficulties.

    6.1.2.2 Time-based Difficulty Schedulingโ€‹

    It will be possible for Dapp Operators to request captchas of different difficulties by different times of the day.

    6.1.2.3 Voting on Captcha Formatsโ€‹

    Initially, the captcha formats will be limited however it will be possible for community members to submit new formats in future and vote on their inclusion in the system. This will increase the variety of available verification methods. This opens up the possibility of distributed reputation stores that each hold their own database of account scores (or credit scores).

    6.1.2.4 Self-referencingโ€‹

    A self-referencing reputation system will be created by assigning some small amount of positive reputation to previously unknown new Dapp Users if they are vouched for by existing Dapp Users with large positive reputations. Vouching may involve some kind of staking.

    6.1.2.5 Provider FRAME Palletโ€‹

    A pallet may be introduced so that the Provider service can become part of the Substrate chain hosting it. This will reduce the need for multiple services to be run by Providers as the Provider Service SDK would not be required, instead replaced by a single substrate node. This strategy may also increase Provider numbers if a major chain adopts the pallet.

    6.2 Promotionโ€‹

    Prosopo will be promoted initially via campaigns directed at Dapp Operators in the Polkadot ecosystem. There are currently interested partners in the NFT space with a desire to prevent bots from registering en-masse to claim the majority of tokens from airdrops.

    6.3 Supportโ€‹

    Prosopo will be supported by the team members who will function as the governing body initially. These roles will eventually be rewarded via a native token and open up to the general public. A community forum and documentation centre will be created to encourage participation.

    Prosopo will be running at least one Provider service to ensure that the network has a constant supply of captchas.

    6.4 Long Term Plansโ€‹

    Prosopo will be ported to other Polkadot contact parachains such as the Moonbeamโ€™s, which enables contracts that use the EVM (Ethereum Virtual Machine).

    The team is committed to contributing to the Prosopo governing body in the long term and fostering community involvement.

    Ultimately, we would like to see innovations in bot detection in the blockchain space and believe that a marketplace for human verification methods is an optimal solution. Whilst captchas are currently the focus, future verification may involve grading the humanness of accounts based on account activity and connections. The Prosopo smart contract and Provider service will be flexible enough to accommodate these new formats.

The goal of the RFP is to develop a decentralized solution on top of Substrate, which can potentially be integrated into Kusama, Polkadot or any other Substrate-based chain as a pallet. The on-chain treasury could potentially sustainably fund the matching pool in the long-run. However, the Web3 Foundation would also be committed to fund a matching pool of the solution for initial test rounds.

    We will build a Substrate pallet in Rust.

    I have friends working at Gitcoin since 2018 and I'm a big fan of their work. I am already a Gitcoin user familiar of the CLR mechanism used in their grants, and think it's a great experiment trying to solve many real-world problems. Transparency has always been one of the highlights of blockchain, and by bringing a innovative and sophisticated funding mechanism on-chain will provide great utility to Polkadot ecosystem. The problem is challenging and fun to solve, and related to the DAO concept of my focus, therefore I decide to gear up and tackle the RFP.

    Project Detailsโ€‹

    We expect the teams to already have a solid idea about the project's expected final state. Therefore, we ask the teams to submit (where relevant):

    * Mockups/designs of any UI components
    * API specifications of the core functionality
    * An overview of the technology stack to be used
    * Documentation of core components, protocols, architecture etc. to be deployed
    * PoC/MVP or other relevant prior work or research on the topic

    The project is divided into two milestones, substrate module and web application.

    In the first milestone we will create a substrate module for the core CLR mechanism implementation, which will include struct, event, error code, and API function definitions. Then, we will build a substrate chain to host and demonstrate the module.

    In the second milestone, we will create a web application interacting with Polkadot.js browser extension to demonstrate the use case of the developed module. The features of the web interface will be similar to today's Gitcoin web UI, however, rather than retrieving the matching donation calculation results from a centralized server, our UI will talk to our substrate chain directly. Upon sending a donating transaction, a user is guaranteed that his/her donation has been recorded in substrate storage and corresponding matching fund will be arranged by the chain.

    A simple flow of the application is shown using below UML sequence diagram. Note that it only demonstrates the ideal case. Interruptions and error cases are omitted in the diagram.

    User flow diagram on Lucid Chart

    Diving deep into possible user scenarios, I find they are more complicated than initially thought. For example, we need to code a way to prevent collusion of two projects, one of which could possibly use the matching fund to vote for the other's application in order to get more funds. That said, we will start with the basic logic and address issues occurred on the way.

    Update #1

    We have completed the initial design of the web app wireframe, so I'm attaching it below. It contains two major pages, the Project Listing page and Project Detail page. The goals of those pages are to clearly present details of participating projects, as well as the matching amount to individual donation. I personally like the user comments and on-chain transactions elements at the bottom of the second page. Not only does it create a plaza for individual donators to speak out, it also connects the donation activity to those voices, thus creating a strong sense of authenticity.

    Ecosystem Fitโ€‹

    Are there any other projects similar to yours? If so, how is your project different?

    There are DAO projects such as PolkaDAO being built on Polkadot, providing utility for fund-raising of private companies. However, our focus is different. This project aims to provide an on-chain crowdfunding solution with a matching function. Specifically, it consists of two components, crowdfunding and matching donations.

    1. Crowdfunding: Individuals crowdfund donations towards public goods (for example: open source software).
    2. Matching donations: These individual contributions are โ€˜matchedโ€™ or โ€˜topped-offโ€™ by a government, grants program, or private philanthropist.

    Besides open-source program grant, the CLR mechanism can be applied to other crowdfunding for public goods, such as government electoral voting and non-profit funding. I have friends running an non-profit organization at Silicon Valley. My goal is to work with her to create the first real-world non-profit fundraising using CLR on Polkadot.

    Future Plansโ€‹

    Please include the team's long-term plans and intentions.

    In my opinion there are tons of things we can keep iterating on, but there are four important areas in terms of future development.

    1. User Study. We should invite a group of beta users for trial and feedback after launch. According to @semuelle, a few questions should be answered in the study plan. For example,

      • How do we choose subjects? What is the target size?
      • What's the questionnaire for the users in the study?
      • How do we measure and make use of the results?

    2. Sybil resistance. As development of this mechanism progresses to production, a number of challenges such as collusion and Sybil attack need to be addressed. Vitalik has proposed a method MACI, or Minimal anti-collusion infrastructure and a project Governance OS Voting from Polkadot General Grant has been working on a solution. We will try our best to integrate those open source projects in order to fight against collusion.

    3. Generalization of incentive protocol. The CLR mechanism, if proven, is one of many ways to conduct crowd-funding for public goods. Just as Substrate provides a framework for any kind of state transition machine, the donation-matching, or even broadly, incentive part should be generalized to easily adapt to other methods. Although new methods need to be coded into the substrate module, but as it evolves, the module will contain most common used methods for the council to choose from.

    4. Reputation protocol integration. The incentive protocol layer sits on top of and relies on reputation protocol. Although the CLR can work without knowing the reputation of a wallet, a lot more advanced features will require a reputations system. For example, without reputation, the risk of cheating is minimum. Therefore, the incentive protocol needs a lot of heavy-lifting work, such as keeping tracking of the relationship of every wallet pair to prevent fraud. Ideally, there will be a reputation layer on Polkadot for our incentive protocol to build upon.

    5. Fund dispensing. We have this idea to raise money for public goods, however, could we also improve the way we spend the money? With the transparency of blockchain, the delivery of the work is open to public for examination. By connecting the developer to the public directly, the product will dramatically reduce the work required from the traditional middleman and create a fair competition among developers.

    6. Social experiment. The project is only valuable when put into real-world scenarios. It, along with Polkadot, are great exciting social experiments. I believe in beta and later production we will encounter challenges on both technical and philosophical sides. It will be an on-going effort to address those issues, and to improve the product as it's constantly put into test.

    Project Overview ๐Ÿ“„โ€‹

    The application is for the new project, which introduces the Quantum Lock -- the proof of quantum work (PoQW).

    Overviewโ€‹

    We are developing an enhancement to the blockchain consensus protocol to enable it to run on a quantum computer. This enhancement allows an existing blockchain to be quantum enabled, and take advantage of the significant potential benefits that quantum computation promise to deliver.

    The most significant benefit is the potential to drastically diminish the energy consumption involved in a classical proof-of-work computation. As our Quantum Lock uses quantum computation with marginal energy cost that is only a fraction of its classical counter-part. (quantum computation is reversible and thermodynamically efficient, thus the expected marginal increase of energy usage of running quantum computation tends toward being comparatively negligible).

    Quantum computing is per se energy more efficient and energy consumption does not scale in the same way for classical computing. By some estimation, the reduction in energy consumption as result of processing data with quantum computing can be a factor of 10^-2 to 10^-3, which is huge. There will be competition in improving the ability to do quantum computing between the nodes but such competition cannot be trivially won by more brute force energy consumption. Consequently, we hope that there will be such a competition enabled by our protocol which can promote genial technological progress in quantum error correction, quantum circuit optimization and distributed quantum computation, which would in turn bring substantial positive impact in various domains. On the contrary, traditional PoW in many sense, unfortunately, has zeroed in on a pattern of destructive competition.

    The Quantum Lock is developed in Substrate and it will be utilised in the QBITCOIN. We aim to integrate the QBITCOIN with the rest of the Polkadot ecosystem, the way of integration (as an independent network with bridge or as a parachain) is to be determined. We are applying for funding in order to cover the initial development costs for the PoQW technology. Our team consists of several quantum algorithm researchers and quantitative finance specialists. The focus on blockchain and the implementation of quantum technologies is a natural fit for our product specialists.

    We chose this path as we realized that a quantum technology enabled blockchain can be energy efficient, as the nature of a proof-of-work can be radically changed with the application of quantum processors. This inspired us to develop the quantum lock and a blockchain ready for the quantum era. Being able to address one of the most pressing problems in blockchain is a major motivation for our work.

    Project Detailsโ€‹

    The Quantum Lock embodies the PoQW. The core of the PoQW is a Forrelation function which is, from the complexity-theoretic perspective, an optimal problem to separate bounded-error quantum polynomial-time (BQP), and the polynomial hierarchy (PH). Without detailing the formal definitions, the class BQP contains decision problems that can be efficiently solvable by a quantum computer within a bounded error. A problem separating BQP from PH can be thought of as the optimal problem to distinguish the capability of quantum from classical computers.

    The project focuses on the implementation of the mechanics of the Quantum Lock protocol. The complementary part of the project is the โ€œforgingโ€œ agent โ€“ the term forging is an analogy to classical mining with an iterative calculation of double hash function. The role of the mining agent is to efficiently perform iterative evaluations of the forrelation function such that the solution is found (see below for details). The calculation can be effectively performed using the quantum computer and this a separate stream of research work in our team. The Quantum Lock itself needs to evaluate the Forrelation function only once to verify the validity of the mined block. This task is achievable for any node with a standard computational resource.

    The first stage of our project aspires to implement the Forrelation function within the Substrate protocol and create a module that can be natively used. In the subsequent stages, we aim to incorporate the Quantum Lock protocol into a full PoQW consensus in a form of an independent blockchain QBITCOIN. We have separated the implementation of the Quantum Lock from the full protocol to stress the difference between the concept and its application.

    Furthermore, the Quantum Lock can be used in a more versatile way and the community could benefit from its independent application. As a complement to the Quantum Lock module, we will provide a wrapper for Python code which access Quantum Resources through Qiskit/Braket libraries. This will allow any Substrate user to easily access numerical modules with quantum subroutine and backends, and thus further stipulate the โ€œquantumโ€œ aspect within the Ecosystem.

    There is an alternative to the proof-of-work consensus protocol, namely do this off chain via offchain worker. This is intended as a further step, where would use the quantum work to serve as a proof of quantum authority (node has ability to perform quantum work). It will be certainly useful when thinking about quantum smart contracts and calculation of useful quantum tasks.

    Mathematical Background: Forrelation Functionโ€‹

    Let us consider two Boolean functions f1 and f2. The Boolean function is in the protocol represented as an array of binary of length nBit. The length of the array is

    nBit = 2 ^ nQubit

    where nQubit is the number of qubits, the parameter which drives the complexity of the problem. For nQubit, there 2^nQubit configurations of bits (and function can take 0/1 on every each of such configuration).

    The basic operation we need to do with the Boolean functions is to calculate forrelation. The forrelation is defined as

    forrelation = 0

    for i1=1,...,nBit for i2=1,...,nBit

    forrelation += b2PM(f1[i1]) b2PM(f2[i2]) (-1)**bXb(v2b(i1,nB),v2b(i2,nB))

    and the forrelation is normalised as

    forrelation=forrelation * 2 ^ (-3*nQubit/2)

    Further, b2PM(b) converts bit to +1/-1, and bXb calculates the dot-product of two bit arrays, which are obtained by function v2b (it converts the integer into bit array).

    The block is considered valid, if and only if:

    forrelation(f1,f2,nBit) within [target-precision;target_precision]

    inclusive the borders. We need to ensure that we use the fix precision of the numbers such that there is no inconsistency in the comparison.

    For forging the block, we need to have f1 and f2 such that the result is withing the allowed intrerval.

    For more references, see the QBITCOIN white paper.

    In order to incorporate the Quantum Lock into the blockchain protocol, we need to amend the information stored in the header. We need to include following items to the header (assuming that certain information is already there, like block id etc), the variables are mentioned in chronological order:

    • Hash of the previous blockโ€“ we use classical hash to refer to the previous block. We will use SHA512 (at least). This will ensure continuity of the chain. Type hexadecimal array of given length. Hash is calculated by double hashing. Hash is taken from the header (data are included through Hash of the Merkle tree).

    • Data โ€“ hash of Merkle tree of the transactions

    • Index of the block โ€“ integer, counting the blocks since genesis

    • Nonce โ€“ not needed (mentioned to stress out the difference to classical mining procedure). The function f2 plays a role of the nonce, the Quantum Lock forging protocol provides this piece of data

    • nBit โ€“ the number of bits to represent function with nQubits qubits used for a given block. This is an example of a value, which can be in the header but needs to be controlled by the protocol so miner cannot cheat. The verification of the block requires check of this value. nBit needs to be strictly smaller than nMax.

    • Precision โ€“ this value is provided by the protocol, it depends on the speed of forging over past the past history. The value can be stored in the header for reference, but needs to be verified by the protocol.

    • f1 โ€“ Binary array of length nMax, where nMax is the hardcoded parameter, which specifies the maximum number of qubits we consider.

      • The value is obtained as follows: Binary representation of the hash of the merkle tree (see data above) and the binary sum with the binary representation of the hash of the previous block. We consider last nBit bits of the array.

    • Target โ€“ The value which is target by forrelation the value is derived from the hash of the previous block โ€“ the link to previous block. Target is a number within (-a,a) interval, where a depends on nQubits.

    • f2 โ€“ Binary array of length nMax. Value forged for the quantum lock.

      • This value, together with f1, Target and Precision are basis of the Quantum Lock (this is a Quantum Lock analogue to nonce).

    • Time โ€“ the time at nanosecond level, when the block is published.

    • Hash-hash of the entire header. - This value does not need to be calculated nor stored, but this is the signature of the forged block.

    Remarksโ€‹

    The key variable determined by the protocol is the Target, which is to be aimed by the forrelation. The value depends on the nQubit. We set

    Target within [-1/2^nQubit;1/2^nQubit]

    The Target is obtained as follows:

    • Take the Hash of the previous block (hash and hash). The Hash is represented by nHash bits.

    • Split the interval [-1/2^nQubit;1/2^nQubit] into (2^nHash)-1 equidistant intervals and thus 2^nHash points, where the smallest one is -1/2^nQubit and the largest one is 1/2^nQubit.

    • The Target is then found by matching the grid point within the interval with the Hash value (when the binary representation converted to integer).

    The genesis block starts with nQubit0. The nQubit can be increased over time. The nQubit never goes down. The nQubit determines the Era of the protocol.

    Forrelation Parametersโ€‹

    Our team is in parallel conducting a research around to assess the parametrisation. In particular, the number of qubits is the leading parameter and will lead the divergence between quantum and classical computer performance.

    Technology Stackโ€‹

    UI Frontendโ€‹

    • A UI forks from the substrate frontend template with a new quantum style theme, used for visualization transactions and block information, add an extra visualization panel for quantum information.

    Blockchain Backendโ€‹

    • Adding a new consensus mechanism called QPoW (Proof of Quantum Work), it will be built as a substrate frame pallet that can be used in all the parachains and even Polkadot.

    • Building a blockchain node client based on substrate framework and PoQW with some modification to the block heads, which can run as an independent chain or a parachain in Polkadot ecosystem.

    • Adding more functions to RPC-API to implement the interaction between the node client and quantum forrelation solver backend.

    Forrelation Solver Backendโ€‹

    • Focusing on the forging part (solving the forrelation problem), built as an independent program.

    • Offering an RPC-API which gives access to forrelation solving ability on quantum computers. It can be used by the PoQW consensus pallet and any other program that needs a forrelation solver.

    • Implementation:

      • Classical solution: an algorithm can be run on a classic computer as a fallback solution when there is no quantum computer available. In the case of classical resources, we consider:

      • Amazon bracket solution: a forrelation solver implemented on the Amazon bracket system.

      • Qiskit solution: a forrelation solver implemented on the most widely used open-source quantum computing library which also contains adapter to many popular quantum computing systems like IBM Q.

    DevOps Pipeline for Scaling Clusters with Quantum Computersโ€‹

    • Building a devcontainer for developers, which can offer a stable rust development and quantum computing environment.

    • Dockerfiles and Scripts used for deploying and scaling clusters with quantum computing on IBM Cloud and AWS.

    Ecosystem Fitโ€‹

    Our project is based on Substrate. We use the modularity of the framework to build all the elements we need to end up with the layer using the proof of quantum work โ€“ the QBITCOIN. In addition, we aim to keep the blockchain connected with the rest of the ecosystem (the best way is to be determined, either to aspire to become a parachain or through bridges). The PoQW and concepts of quantum computation can enhance the entire ecosystem, making Substrate/Polkadot the first truly quantum enabled block chain.

    The primary audience are the users of the QBITCOIN, which is a blockchain on its own. We do however anticipate in the next iterations to deploy the Quantum Lock across different applications (bridges, for instance).

    Firstly, our project introduces the proof of quantum work and thus bridges the abrupt development in the quantum computing with the blockchain. Across the board, every industry is preparing for the adoption of quantum computing and the Quantum Lock is doing this task for the Polka ecosystem. Once the PoQW is deployed, the quantum resources can be further extended and used across (quantum) smart contracts. Secondly, the Quantum Lock gives an extra protection to the consensus against the adversarial quantum miners as the Quantum Lock scales with the growing quantum power and keeps it is proof of work integrity. Last but not least, the application of Quantum Lock and PoQW paves a way to significantly ameliorate the carbon footprint of classical PoW, since it is energy efficient and de facto serves as a proof of quantum authority rather than burning protocol burning significant amount of global available energy.

    Existing projects with quantum computing focus on quantum security, mainly using the lattice cryptography algorithm. Our approach is different, as we focus on integrating quantum technology with the consensus protocol itself. In addition, the Quantum Lock aims to create an economic activity for available quantum resources, which will in turn stimulate the continue development of the quantum computing industry, thus creating a desirable positive feedback loop. The ecosystem that adopts quantum resources early will first and for most enjoy the spring of opportunities coming with the dawning the quantum era.

    Our long-term plan is to implement the full blockchain based on the proof of quantum work. We use Substrate to be able to bridge to other protocols. The Quantum Lock can be used across different projects and we consider this is a first step to bring the quantum computation into the blockchain โ€“ utlimately, we envisage the creation of the Quantum Smart Contracts, where Quantum Computation will be available through the contract.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    We are NeoPower, a Web3 software company. We are currently building a payment automation platform called Roloi.

    Last year we received a W3F Grant for the migration of our Streaming Smart Contract from Cosmos to Polkadot. We talk about this migration journey in a Medium Article.

    Roloi is based on three automation pillars:

    • Token streaming
    • Recurring payments
    • Conditional payments

    As a next step for Roloi, we are going to build the recurring payments feature.

    Roloi can achieve this by avoiding off-chain mechanisms thanks to OAK Network: the automation parachain.

    Project Detailsโ€‹

    Goalโ€‹

    Automate ink! smart contract transactions in a recurring way.

    How to achieve itโ€‹

    We need to notify our Smart Contract deployed on Shiden (Astar) whenever a scheduled transaction should be executed.

    XCM enables us to connect parachains. This way, we can schedule transactions on Shiden (Astar) with the assistance of Turing (OAK).

    Technical detailsโ€‹

    Creating products using XCM implies a complex journey today. Here is an example between Astar and OAK:

    W3F Grant - XCM Payment Automation

    There are some DX/UX issues while building products with the out-of-the-box approach:

    • The process to enable the connection between chains requires the configuration of Proxy Accounts on both chains.
    • Users have to manually top up their Proxy Accounts in order to allow them to pay for fees to act on their behalf.
    • XCM messages are complex to understand and generate.
    • Managing on-chain recurring transactions is always a complex task.
    • Polkadot.js is great for low-level development, but hard to use for user-oriented products.

    Our solutionโ€‹

    Our deliverable will include a Next.js UI and an ink! smart contract to create recurring transfers leveraging XCM features.

    The included features on the Next.js UI are:

    • โœ… Wallet connection
    • โœ… 1-click proxy accounts setup
    • โœ… Recurring payment creation
    • โœ… Incoming and outgoing payments section
    • โœ… useink() library

    For devs:

    • ๐Ÿ’ป Our own useful hooks and reusable abstractions in Typescript to encapsulate tasks such as:
      • Creating proxy accounts on both sides
      • Depositing funds into these accounts to cover fees
      • Wrapping the recurring transaction to be executed via Astar Proxy Account
      • Transmitting the recurring task configuration via XCM & HRMP
    • ๐Ÿ’ป ink! smart contract example used to trigger payments
    • ๐Ÿ’ป Recurring payment data model

    Some hook examples: W3F Grant - XCM Payment Automation - Hook examples

    This project will be generic and open source to serve the Polkadot builders community as a public good that teams can use to automate transactions leveraging cross-chain features.

    This will make building with XCM fast and simple.

    Ecosystem Fitโ€‹

    This project is a public good for the Polkadot Builders community. For NeoPower, this will be a great experience since all of this work will give us more traction to grow Roloi.

    Our intention is to provide a generic and open-source project that can be the starting point to many real use cases of cross-chain payments using XCM.

    The code will be backed with robust and clear documentation. This will allow our platform to be easy-to-use and effortlessly scalable.

    We also plan on publishing a Medium Article to share our experience developing with XCM.

    Saito Gaming Protocol and Library

    Project Overview: Introduction to Saitoโ€‹

    Saito is a data-network that allows developers to write web3 applications that run inside browsers. Our network is similar to a blockchain in the sense that it does not need an owner to pay for its servers. Where Saito differs from traditional blockchains is that it does not have miners or stakers or validators and does not have a permanent ledger.

    This can make Saito confusing on first encounter. The network has some of the properties of a layer-one blockchain, but it is also a transient broadcast layer. Our community is building chat, email, gaming and other web3 applications, but these applications need to integrate with other blockchains when they want to add asset-transfer and smart contract functionality. When it comes to the rest of the blockchain space, Saito's role in the ecosystem is basically bringing the throughput and cryptographic tools to shoulder the burden of handling off-chain data flows, and generating fee-bearing transactions for other blockchains (or parachains) where permanent on-chain transactions are required.

    Because of this, the most similar thing to Saito in the cryptocurrency space is metamask. Both allow developers to write applications that run in web-browsers and use blockchains. The difference is that metamask relies on Infura to provide a network while Saito provides one that pays for itself. The Saito approach is superior because it is an open network layer that cannot be privatized. And it elegantly pays for user-facing network infrastructure without the need for IFPs or corporate subsidies. Saito is also blockchain agnostic in the sense it can be deployed as a UI-layer without the need for the underlying blockchain if network operators are willing to accept zero-fee transactions.

    We believe that as Saito continues to grow developers will look at applications like the Saito Arcade and embrace this method of developing web3 applications. To make the applications our community is building truly web, we need our platform to be able to interact with Polkadot and its parachains so that Saito applications can send-and-receive NFTs and other financial assets. To use the metamask analogy above, this is essentially the step where we add ETH support and our community starts to incorporate money-functions directly into their games and other applications.

    This proposal outlines how we would like to accomplish this. Our goal is to increase the power of Saito as a metamask-layer by enabling our applications to interact with the non-transient ledgers provided by Polkadot and its parachains. To make sure this delivers value to the Polkadot ecosystem, we propose to start by integrating the gaming applications that are driving double-digit monthly growth on our platform. We believe this will be a win-win move. Polkadot will gain gaming traffic and transaction volume, while Saito users can start deploying parachains and transferring financial assets across them directly in their browsers.

    Overviewโ€‹

    To accomplish this in a manner that will attract developers, we propose integrating Polkadot and Polkadot parachains with the web3 games that are driving growth in our community. We believe this will help both projects. About eighty percent of Saito transaction volume is coming from online gaming, so this is a practical area where we can deliver transaction growth and developer attention to Polkadot along with a new class of gaming applications. Having Polkadot integration and the ability to interact with NFTs and parachains meanwhile makes Saito more compelling as a user-facing network layer.

    To understand how Polkadot can benefit from integration with an open web3 gaming library, let us briefly explain what it is that we are building. Historically, most "blockchain games" in the industry use blockchains to deposit and withdraw money, hold random number lotteries, or to manage NFTs that represent in-game assets (weapons, land, etc.). These use-cases require blockchains to serve as a holder of financial assets. The standards for how these assets are created and managed on-chain are best defined by POLKADOT developers and is not the sort of standard we are discussing. Substrate can simplify the process of deploying these tremendously.

    The standard we are building concerns how to define the language of game moves in sequence. To make this clearer, understand that in the games that developers are building on Saito, players broadcast moves to each other and execute them in parallel from a stack of gaming instructions that are kept synchronized via the metamask-like network. This approach eliminates the need for middlemen like Steam to connect users or control gameplay, while it enables cryptographic techniques like "mental poker"12 to be used to ensure provably-fair deck shuffling, dice rolls and other core game functions.

    We already have over a dozen sophisticated games that people can play that adopt this approach: sharing moves between players and executing them in parallel in the browser of each player. These games use an open protocol we have been developing that define how game moves should be broadcast and executed in browsers. This protocol (instantiated in a supporting library) removes the need for developers to implement common techniques like deck-shuffling, random number generation, card deals and otherwise complicated tasks like simultaneous moves. It is important to note that this protocol and library are chain-agnostic: while the games our community are building are deployed atop Saito, it is possible to deploy them on other blockchains or even non-blockchain peer-to-peer networks.

    Integrating NFT and asset-transfer functionality means expanding this protocol so that in additional to handling shuffling, turn-management and those sorts of common cryptographic operations, it also provides ways for developers to transfer in-game assets on Polkadot simply by broadcasting a game move. In the next section we provide more details about how our web3 protocol standard and reference implementation works in order to make it clear why this is necessary and the benefits it will bring to the web3 ecosystem. Section IV then outlines how we will deliver it in three stages spread across two months. Section V closes this proposal with examples of real applications that already exist - making it clear we are talking about solving practical problems that deliver applications that will be immediately able to interact with Polkadot and benefit from parachain deployment.

    Project Detailsโ€‹

    The overarching goal of having a protocol and reference game library is simplifying Web3 game development by creating a standardized method for describing common game moves that can be executed in parallel on different user computers rather than in smart contracts managed by a central blockchain. The reference library is also needed so developers can build games with it directly or consult it as a reference tool when tackling similar problems or porting games between networks by developing competing reference implementations.

    To make it clear what we are talking about and why it is important, let's start by describing a practical problem common to many games - the need to shuffle a deck of cards and deal them out to many players. In a typical game, this is handled by custom code or the use of closed game-engines that don't play nicely with the open web3 ecosystem.

    In the stack-powered development method, a developer that wishes to have cards dealt to a player needs only add a single instruction to the game stack. This can be done by broadcasting the move to all other players in the game who add it to their respective stacks on receipt of the move. As an example, the following command instructs the game engine to DEAL a total of 5 cards from card deck 1 to player 2:

    DEAL 1 2 5

    When this command is executed in parallel on all player computers, the underlying game engine takes over, adding sub-moves to the stack that prompt players to send player 2 the necessary keys they need to decrypt the 5 cards they are pulling from the deck. Control then passes to the next instruction on the stack, which may prompt player 2 to select one of their newly issued cards, or perhaps discard two cards and then re-shuffle the deck. Each game is obviously unique: the point of the protocol (and supporting library) is to eliminate the need for developers to touch the underlying cryptography and let them focus on game-specific UI and logic.

    The starting point for a robust gaming protocol / engine is:

    • shuffling cards (game assets)
    • dealing cards to players (private)
    • dealing cards to piles (public)
    • moving into a player turn
    • rolling-dice (secure random number)
    • simultaneous card-selection
    • simultaneous game moves
    • player alerts and log management

    While the protocol can ultimately be ported to any language, our starting place is javascript (NodeJS) as browsers provide the UI for most web3 blockchain games, and this is what our developers are building and where they need integration with permanent ledgers like Polkadot and its parachains.

    Our work on developing this library and adding features is ongoing: at present our standard handles somewhere over half of these requirements. Features tend to get added as games are added which need them, and documentation is developed after the fact. To simplify Polkadot integration, we will prioritize implementing the remainder in a standardized javascript (NodeJS) implementation that is well-documented, has an intuitive API with non-ad-hoc naming conventions ("DEAL", "SHUFFLE", "ROLL") that is available under a flexible open-source license. This will enable games and web3 development to occur across multiple blockchains and networks. \

    Our proposal begins with the next step: extending this open standard to add commands that let developers programmatically handle blockchain / asset / NFT transfers within games as well as the in-game moves it already supports. Just as the gaming protocol / library permits developers to trigger a deal or shuffle a deck, so must it support users making deposits, confirming receipt of assets and/or NFT tokens, transferring them to other players, or otherwise engaging with assets on external ledgers. This functionality is needed both within gameplay as well for industry-focused cases such as letting users prove that they have purchased a game or handling real-time payments to game publishers on game creation.

    The protocol needs to support the following use cases that should be provided by permanent ledgers:

    • checking account balances
    • sending tokens to accounts
    • confirming receipt of tokens

    Adding asset-transfer commands into the game engine will create a powerful backend that can be deployed across different parachains (no user or developer lock-in) and permit integration between asset-transfer networks and the high-throughput web 3.0 data services supported by the metamask-layer. The game library meanwhile abstracts away everything that is difficult about on-chain game creation.

    Adding these features will also web3 games to support use cases like: ensuring users pay the game publisher prior to being able to play the game, in-game transfers of funds or NFT assets between players depending on what happens in gameplay. There are many use-cases where a large gaming community or tournament may even want to create a dedicated parachain to manage ranked-games, leaderboards, buy-ins and payouts and more.

    Our goal building this is encouraging third-party developers to roll out more games using open standards, raising awareness of the power of blockchains for on-chain gaming via the Web3 Foundation and taking part in the shift that is coming from centralized to decentralized gaming networks. Funding is sought to justify prioritizing resources on Polkadot integration and make sure we can devote the needed time to apply polish to the documentation and other developer-focused assets so the library/engine can be of use to external developers.

    Ecosystem Fitโ€‹

    Saito is deeply committed to web3 and our stack is focussed firmly on helping make it simple for developers to bring truly decentralized applications, on line automomy and new business models to users. Adding the ability to interface with parachains, as a bridge to the Polkadot ecosystem opens up a world of financial and other tools to those developers, and provides developers working in or interested in the Polkadot ecosystem a fast simple way to get started. Gaming is the perfect proving ground for this.

    1.Saito ModulePolkadot module that allows Saito applications to connect to a Polkadot API access point to send / receive network Polkadot data. This module would be the equivalent of "metamask" application for all of the existing games and applications already running on Saito. It would run fully in-browser.
    2.DocumentationInline documentation and published how to guide.
    3.Environment BuildBuild and test environment containing Polkadot node and Saito Stack.
    Test interoperability and benchmark performance.
    Document configuration, deployment and management.
    Deploy against public test net.
    4TutorialDeveloper tutorial showing how applications can integrate with Polkadot module on a base-level (i.e. without the need for use of the gaming API layer), making Polkadot a first-class citizen for all Saito Web3 applications and allowing all of them to send and receive payments in DOT.

    Details:

    The point of building this module first is to have a set of local API functions that our own communications stack can use when the open game library needs to make API queries to the external Polkadot chain. Relying on local interface simplifies the coding of the game library so that networking and chain-specific connection information can be abstracted away. This is critical for keeping the game library cross-chain portable, ensuring that it will run on any blockchain or parachain, and removing the need for the game library itself to handle networking code.

    A side-benefit of building this module first is that Polkadot and parachain tokens become A-class citizens on the Saito network. Getting this module written and documented first allows all games and other (non-stack) developer applications to send and receive Polkadot. Polkadot or parachain developers who want to port or hack any existing Saito applications will be able to do so while having the application handle their own native token.

    A plug-and-play Saito module will also simplify building UI components and web applications for Polkadot that monitor or interact with the chain through an API-access point. Getting this functionality out first allows us to reach out to the Polkadot community with an immediately-useful solution for certain classes of Web3 application-development work. \

    Timeline Notes: Three weeks should be adequate for building and documenting this module, as well as putting together a tutorial demonstrating how independent Web3 modules can make API requests and check account balances. Part of this work will obviously require setting up and running API infrastructure so we can make the process as painless as possible for developers, etc.

    Milestone 2 โ€” Asset Transfers in Gaming Protocolโ€‹

    • Estimated Duration: 3 Weeks
    • FTE: 1.5
    • Costs: 0.75 BTC
    NumberDeliverableSpecification
    1.Protocol and Library UpgradeToken-specific transfer instructions added to game engine / protocol.
    Code addig Stack-based instructions for applications adding the following common game mechanics:
    • player Y deposits assets
    • player Y sends assets to player X
    • player Y requests balance
    2.DocumentationInline and published documentation of library extensions.
    3.GameProvision of at least a single open-sourced game demonstrating the features.

    Details:

    Combine the previous API work with the game protocol work to add financial asset transfers and payment functionality into the underlying protocol and game engine. This will be entirely new functionality. It will allow developers to do things like check that payments have been made prior to gameplay or send and receive assets during play.

    We suggest the creation of a "play-for-charity" game to demonstrate the required financial use-cases (players deposit tokens, players send those tokens to each other and in case of loss send the funds to a charity) without the need to worry about legal issues surrounding gaming. Another idea might be a game that requires players to submit proof-of-payment to be permitted to play the game.

    Regardless, this work is done last as it builds on the experience of both the initial Polkadot module, as well as the work expanding and systematizing the protocol. Since in some ways it is the most interesting part of the project, we also want to leave it for last so that the community will be aware of the work being done and ideally come in with suggestions on which games to port and which particular features to focus on first.

    Timeline Notes:

    We expect it to take about four weeks to do this work. Two weeks are probably sufficient for the initial protocol and game library work. We will need to add another two weeks to get a workable / fun game built that demonstrates the functionality and has enough polish and design work done that it feels like more than a playable tutorial. We hope to get a sense of the best sort of game to build by talking with other gaming projects in the Polkadot ecosystem to get a sense of what they are doing with NFTs on their parachains.

    Community engagementโ€‹

    The Saito team will publish regular updates on developments and milestone completions. This project represents a great developer outreach opportunity for Saito, and to bring much anticipated features from the Polkadot ecosystem. There will be many opportunities to promote this to our growing community and specifically to developers working on Saito, and those in the Polkadot space.

    More importantly Saito will seek out a partner project working on NFTs or other tokens on a parachain to colaborate on building a game in which these tokens are issued as prizes, trophies, in game assets, achievement badges or similar. This would cap off the work done as part of this grant, and set the stage for broader colaboration.

    Future Plansโ€‹

    Our hope is that this work continues well into the future, and that the Polkadot community embraces not only the sort of open source games that our community is producing, but the more flexible style of application design that comes from in-browser stack-based program execution instead of offloading everything into smart contracts.

    Should it become apparent that a game protocol compliant substrate module could be valuable to Polkadot and the community, we would investigate building such. Either under a separate grant or in colaboration with the Polkadot community.

    Our criteria for success is our ability to build community around feature-rich games. Our hope is that integration with Polkadot and other financial parachains brings value to Polkadot users, programmers, and our own gamers. We are happy to work with other chains and communities to bring their valuable features into our gaming environment. The shared goal is an open ecosystem that is more attractive than closed source competitors like Steam and the Apple Store.

    Our criteria for failure would be spending a significant amount of our time building foundational tools that do not drive game development and community growth. We think this unlikely, as our own community is growing rather quickly and there is a clear need for Web3 games to integrate with asset-class blockchains and parachains.

    The Saito Project has seed support.

    The images below are from playable games that are currently running on the Saito network (https://saito.io/arcade). In addition to building their own games, developers are able to start building payment functionality on top of these and other games immediately upon this project being completed.

    Games generally available for play around the network include Chess, Wordblocks, Twilight Struggle, Red Imperium, Poker, President, Solitrio, Scotland Yard, Thirteen Days, Pandemic, and several others. Most games support anywhere from 2 to 8 players and take anywhere from 15 minutes to 6 hours of time to play through completion.

    SARP - A Static Analysis Tool for Runtime Pallets

    • Team Name: Supercomputing Systems AG (SCS)
    • Payment Address: 0xd24622311a22470353bd21d9bcd9e02ba0cfebbe (USDC)
    • Level: 1

    Project Overview ๐Ÿ“„โ€‹

    This application is a response to the RFP Static Analysis for Runtime Pallets

    Overviewโ€‹

    Runtime Pallets are modules for writing the business logic of blockchains in Substrate (a Rust framework for building blockchains). These are usually concise pieces of standalone code with relatively few dependencies and clear specifications, hence tractable targets for performing static analysis and verification. The code quality of a runtime pallet is crucial, as even minor defects can result in major exploits like DoS attacks or the stealing of funds by a malicious party. A static code analysis can help to automate the auditing processes and prevent introduction of defects throughout the software life-cycle.

    Therefore we would like to develop a tool - SARP (Static Analysis tool for Runtime Pallets) to perform static analysis with reasonable soundness guarantees. In particular, we would like to target vunerability classes that are detectable using dataflow analysis techniques like tag analysis and taint analysis.

    Our team has no prior knowledge in static code analysis, but has a good understanding of substrate and Rust.

    Project Detailsโ€‹

    We will base our work on MIRAI and extend it with checks on substrate pallets. For details see the Development Roadmap

    Ecosystem Fitโ€‹

    The tool will help any team developing substrate pallets. It can further be integrated in the CI pipelines of the teams, providing a continuous quality check on the pallet code.

    In the long term it could be interesting to connect the work done here with the new emerging auditing DAOs (like Fuzzland or QRUCIAL DAO).

      • a comprehensive user tutorial, incl. documentation on the risks of each vulnerability
    3. Add more features including checks on the following vulnerability classes:
      • tracking bad randomness: ensure bad randomness does not leak into sensitive functions.
      • detect panics statically to avoid potential DoS attacks: these include unsafe arithmetic operations, access outside bounds, assertion failures, etc.
      • tracking unsanitised input leakage for sensitive functions.

    Once we have a tool with a good feature set and basic usability features, we want to promote it to the Polkadot developers. Once the tool is in use, we hope to receive feedback on further features and improvements by the developers.

    Project Description ๐Ÿ“„โ€‹

    SensioNetwork is a decentralized protocol that empowers content creators to sign, permanently record, and claim statements about their ownerships and copyrights, allowing them to license their work and get paid. SensioNetwork is an integral part of a much larger project called Sensio which consists of two more sub-projects.

    SensioNetwork's applications(dApps), Sensio Photo and People-2-People marketplace, have a potential of reaching millions of people and boosting the ecosystem's reputation and adoption.

    SensioNetwork will be implemented as a Substrate-based chain with its token, currently named THT.

    SensioNetwork is the backbone of the Sensio project. Building the SensioNetwork with Substrate and in the Polkadot, ecosystem matches our principles and views on interoperability and interconnectivity. One of the Sensio's goal is to establish a fair and trustworthy multimedia market, primarily for photography, and we can do that only with a flexible blockchain solution.

    • Total Estimated Duration: 6 weeks
    • Total Costs: 0.5 BTC

    Building the modules follows a least-dependency approach, which means that we will build the modules that are most dependent on first.

    Milestone 1โ€‹

    In this milestone, we want to build a working Substrate-based chain and PoE runtime module.

    PoE is an essential step towards generating any kind of statement. The ruleset in SensioNetwork is based on the flexible implementation of PoE. Each of the Proof-of-* modules depend on the information to exist before it can be verified. The structure is slightly different for each of the input types. In the case of the photo, there is more than one identifier since each photo can contain the metadata. Our tasks in this milestone are to define the generic structure and rule-set as well as the rules specific for the photo type. The rules should be much interoperable as they can. One potential solution to this is utilising the CID and multihash library.

    Milestone 2 - Canceled via Elementsโ€‹

    In this milestone we will start working on PoCLO, implementing the connection to PoE and working on the implementation of the rules and data validations. By the end of this milestone, we will have the working runtime that validates that equipment information already exists in PoE and has never been claimed and can create the ownership statement for a given input.

    We have developed the algorithm for PoCLO in nodejs and the workflow is built with different architecture in mind. We must change it to fit the current solution. This module will be in charge of creating records for provable camera/lens ownership statements. The current implementation is built with React in our Proof-of-Concept webapp. PoCLO is a process that is very similar to what is used in image forensics. It's our first step to registering provable ownership statements. Our current solution uses PKI and CID, which we will keep in the future together with the SSI and DID.

    Gentle overview on the process:

    Ownership and copyright process

    • What work has been done so far?

    At the moment we have PoC, web app + Graphql API + naive DAG, that we built as a showcase. We have the core functionality of all three sub-projects (very basic so far), photo upload and editing, claiming ownership and copyrights, selling ( for free, as it's a PoC ) and copyright request with approving and declining outcomes. We truly believe that (D)PKI or its variants are the future, that's why all users are given ed25519 asymmetric keys and passphrase emailed. That key is used for signing and verification.

    • Are there are any teams who have already contributed (financially) to the project?

    Only the founders, Daniel Maricic and Elena Tairova.

    • Are there any other projects similar to yours? If so, how is your project different?

    Some projects share a similar approach, like the majority of PoE/TimeStamping, but none of them does what we are trying to accomplish. Sensio, at the moment, is the only project out there that provides verifiable ownership and copyright claims based on real workflows, not first came -> first hashed it -> owns it.

    • The team's long-term plans and intentions with this project.

    SensioNetwork is the core part of Sensio and its applications which development is underway. First, the Digital Asset Management software for professional photographers will be launched, and later, with this community acting as ambassadors, we can expand to the mass market of smartphone holders. Well-established user-base and strong USP (connectivity, optimal protection of online IPR) will in its turn put Sensio in a position to disrupt the market of stock photography and video. Once launched, People-2-People marketplace will allow publishers, marketers and other creatives to acquire quality content directly from its author. Thus, a fairer and more efficient market for all the actors.

    Project Overviewโ€‹

    Overviewโ€‹

    Since Polkadot-based chains are fee-optional, transaction fees currently being used as an anti-spam mechanism can be leveraged to make every transaction on Polkadot carbon negative, without requiring any changes to the user experience. We propose a common good parathread on Polkadot, named Sequester, that provides the functionality of aggregating transaction fees, exchanging them into carbon-backed tokens, and retiring underlying carbon offsets that meet the communityโ€™s specifications.

    Sequester is a toolkit that will allow any chain in the Polkadot ecosystem to easily buy carbon-backed assets and retire associated carbon credits. By retiring these carbon credits, we aim to incentivize the creation of more high-quality carbon reduction projects by substantially increasing demand and the economic viability of this work.

    Due to Polkadotโ€™s shared security model, the network is uniquely positioned to utilize existing network activity to natively power a carbon sink. With the widespread adoption of Sequester across its growing ecosystem, Polkadot has the potential to power one of the largest carbon-offsetting entities worldwide.

    For more information, see our full white paper.

    Project Detailsโ€‹

    To allow chains to sustainably leverage their transaction fees to buy carbon credits on-chain, we will need to handle:

    1. Receiving tokens sent from other chains
    2. Exchanging those tokens into carbon-backed tokens, and
    3. Initiating retirement of the underlying assets for the carbon-backed tokens

    This grant addresses step 1. Specifically, we will implement a pallet that will calculate a chainโ€™s transaction fees over a period of time and allow any chain connected to Polkadot or Kusama to send a percentage of them to Sequester.

    Ecosystem Fitโ€‹

    Sequester is building the infrastructure to allow any chain in Dotsama to donate a portion of their transaction fees towards buying and retiring carbon-backed assets. We aim to provide parachain developers a simple way to integrate Sequesterโ€™s functionalities into their chain. We hope to lead the charge in implementing Polkadotโ€™s environmental strategy. With the widespread adoption of Sequester across its growing ecosystem, Polkadot has the potential to be one of the largest carbon-offsetting entities worldwide. We visualize and explain this process in the diagram below:

    0c.TestingOur code will have full unit-test coverage to ensure functionality and robustness. We will also provide documentation describing how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) to run a test node in order to test that our pallet functions correctly.
    1.Calculate Transaction FeesInside our pallet, we will create a method that calculates the transaction fees over a period of x blocks. For the fee-calculation, we will be using an off-chain worker to index the transaction fees on a per-block basis and store that calculation in off-chain storage.
    2.Send to SequesterImplement a method that will retrieve the sum of transaction fees from offchain-storage and will send a percentage (a configurable variable) of them to Sequester's chain via XCM every x blocks (also a configurable variable). This transfer process will be automated so that no manual transfer will be needed by the parachain through governance. This method will also handle resetting the proper off-chain variables.
    3.Article/TutorialWe will provide a full tutorial outlining how to add the pallet to your chain. This will be added to the wiki of the sequester website.
    4.Weight estimationWe will provide reasonable weight estimations, e.g., using benchmarking.

This will only implement a simple launchpad crowdsales substrate pallet. While we intend to implement this protocol in Setheum, it is not yet ready for production and might currently have unknown issues, therefore this does not represent the final state of what is intended to go into production on our main chain implementation, and we do not intend the current implementation to have the robust functionalities of a production-level launchpad platform. This will instead only result in an initial test network for evaluation purposes.

    Shadows Network

    • Payment Address: 198yWGziNfUgrTXf6QiUC5QqEhJ34cyxf
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    Shadows Network is a Polkadot parachain based on Substrate. As long as you consider valuable assets, they can be synthesized on the chain through Shadows Network. And Shadows network is a decentralized financial integrated platform integrating stablecoins, collateral lending, asset synthesis, and derivatives trading. will introduce a trillion-level derivatives market into the Polkadot ecosystem.

    Overviewโ€‹

    Shadows Network is a Polkadot parachain based on Substrate, focusing on synthesizing derivative assets into the Polkadot ecosystem. It is like the "shadows" of real assets on the blockchain. Shadows Network will open up the channel for real assets to be synthesized to the blockchain. Real assets that you think are valuable can be synthesized through the Shadows protocol to achieve decentralization of asset value. Shadows Network pioneered the "debt pool" model, which has the advantages of unlimited liquidity and zero slippage on-chain transactions. It has a more friendly transaction experience and lower transaction costs than other centralized exchanges and SWAP.

    Shadows network will strive to become one of the Polkadot parachains by participating in the parachain slot auction. However, even if the slot usage rights are not successfully obtained by then, the shadows network will also be counted as parathreads to obtain cross-chain capabilities.

    Most of our team members come from first-line Internet companies, cryptocurrency wallet companies and cryptocurrency exchanges. They have participated in the development of multiple blockchain projects and have in-depth research and accumulation of blockchain technology. We have developed many dapps based on Ethereum. Due to the limitations of Ethereum itself, many of our ideas cannot be implemented and realized on Ethereum. We have done in-depth research on Polkadot and Substrate technology, Polkadot's cross-chain technology, parachain slot, governance model, etc. We believe that Polkadot is one of the most advanced technologies and concepts at present. What Shadows Network wants to do is to synthesize assets into the blockchain, so that everyone can truly control their assets and realize asset security and asset transaction security.

    Project Detailsโ€‹

    The Shadows Network architecture design includes: DOSใ€MintXใ€Exchangesใ€Fee Poolใ€Debt Poolใ€Liquidation and Off-chain Workers.

    DOS

    DOS token is a governance token issued by Shadows Network. All synthetic asset are backed by DOS token. synthetic asset are minted when DOS holders stake their DOS as collateral.

    MintX & xUSD

    DOS holders can mint xUSD through MintX by stake DOS. MintX is a reactor for synthetic assets. xUSD is a stable currency issued by Shadows Network. xUSD is minted by stake DOS and The mortgage rate of DOS must not be less than 800%. All synthetic asset transactions will be conducted around xUSD.

    Exchanges

    Shadows.Exchange provides many advantages over centralised exchanges and order book based DEXโ€™s. All trades are executed against the contract, known as P2C (peer-to-contract) trading. Assets are assigned an exchange rate through price feeds supplied by Off-chain workers, and can be converted using the Shadows.Exchange dApp. This provides infinite liquidity up to the total amount of collateral in the system, zero slippage, and permissionless on-chain trading.

    Fee Pool

    When SyAs are exchanged through the Shadows Exchange, a 0.3% fee is extracted and sent to the fee pool to be claimed by DOS stakers. When claiming fees (also called SyAs exchange rewards) a staker also claims their DOS staking rewards, which reward them with extra DOS for staking the DOS they currently have.

    Debt Pool

    The system tracks the debt pool (as well as each individual stakerโ€™s debt) each time an DOS holder mints or burns Synths. It does this by updating the Cumulative Debt Delta Ratio. This measures the DOS stakerโ€™s proportion of the debt pool at the time they last minted or burned, as well as the debt change caused by other stakers entering or leaving the system. The system uses this information to determine the individual debt of each staker at any time in the future, without having to actually record the changing debt of each individual staker.

    Liquidation

    In order to avoid systemic risks, We introduced the introduced liquidation. When the staker's position is lower than 750%, the system will prompt the liquidation risk. If the position has not been increased for a period of time, the collateral will be liquidated.

    Ingester

    Ingester is our implementation of Off-chain workers. The prices of all synthetic assets in the Shadows system need to query and/or process off-chain data before it can be included in the on-chain state. The conventional way of doing this is through oracles. But oracle still has several flaws with respect to security, scalability, and infrastructure efficiency.

    To make the off-chain data integration secure and more efficient, We use Substrate off-chain workers. The off-chain worker subsystem allows execution of long-running and possibly non- deterministic tasks (e.g. web requests, encryption/decryption and signing of data, random number generation, CPU-intensive computations, enumeration/aggregation of on-chain data, etc.) that could otherwise require longer than the block execution time.

    Ecosystem Fitโ€‹

    We have a deep understanding of many projects in the Polkadot ecology, and found that there are several projects that we think it is necessary to list to make a difference explanation, Acala, Laminar and Coinversation:

    The main difference between Shadows Network and Acala Network is that Acala's swap and liquidity mining have the risk of lack of liquidity and the pain points of high slippage. The original "debt pool" mechanism of shadows network has the advantages of unlimited liquidity and zero slippage trading. Acala's stablecoin and lending business rely heavily on the third-party oracle chain link, which has some shortcomings in security, scalability, and basic efficiency. The shadows network will use the off-chain workers provided by Substrate to improve this. , Safer and more efficient.

    Laminar relies heavily on off-chain asset collateral, such as U.S. dollars, which has the shortcomings of inefficiency and inflexibility, while the shadows system uses digital assets such as DOT, DOS, BTC, ETH as collateral, which is more flexible, efficient and safe, and users The options are more extensive.

    Coinversation is not a parachain and based on the ink! smart contract depends on the existing parachain. The shadows network develops parachains based on substrate. Based on the rust language and Substrate's forkless runtime upgrades, the shadows network is more efficient and flexible.

    Coinversation currently relies on a centralized oracle, which has the risk of being opaque and easy to operate, while the shadows network parachain is based on the off-chain worker of the substrate, which can achieve little dependence on the oracle, which means that the oracle is brought about The risk is also smaller. We haven't seen any "Liquidation" plan in Coinversation, and shadows network has a more complete liquidation mechanism to avoid systemic risks.

    From the above analysis and comparison, shadows network has obvious differences from several other products. Shadows has a more complete design and better technical solutions, and we have considered more mature risk control.

    Development Roadmap ๐Ÿ”ฉโ€‹

    We expect that the entire project will be split into two grants. The first grant includes the development of parachains and the implementation of core modules. But only documents, test cases and api are provided. But through the API, you can already participate in the casting and trading of synthetic assets. The second grant will include the development of a complete user interface, dapp, and wallet. It will be a complete product that can be experienced by then. Users can directly experience the functions without knowing the technical details.

    Signet - Talisman

    • Team Name: Paraverse Foundation

    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Signet is blockchain-native financial workflow management software for enterprises.

    The goal of Signet is to enable enterprises to perform blockchain operations such as treasury management, payments, staking and governance in a way that is friendly to non-technical users but include similar "best practice" risk management controls to how they may operate in web2 today.

    We believe enterprise adoption will be one of the central narratives of the transition to Polkadot 2.0, and the capabilities of the Signet platform will enable this to happen in Polkadot, enabling enterprises to feel comfortable to inject liquidity into the ecosystem.

    Signet is built natively on top of Substrate, including the multisig, proxy, governance and staking pallets, but adds an open-source self-hostable software layer on top that enables configurable workflows for the purpose of internal risk mititgation.

    Signet was initially created out of Talismanโ€™s user research, which revealed that teams faced many difficulties and risked mistakes when trying to run their on-chain financial operations, and ended up choosing convenience over security. In mid 2023, the Signet team was formed within Talisman to focus on B2B and enterprise opportunities.

    We believe what we are proposing is a great candidate for W3F funding because of two reasons:

    1. The common good aspect of a documented, integratable Sign in with Substrate (SIWS) reusable component, coupled with the halo effect it will have on Substrate adoption by providing a new avenue for both existing web2 and current web3 developers to build for the ecosystem.
    2. The importance of usability for larger organizations, enterprises and institutional users, who find it difficult today to use overly technical tools such as Polkadot.js. We believe strongly that ease of use and understanding are extremely important when trying to achieve security, in practice, in an enterprise context, and by delivering this, Signet will enable liquidity to flow into the ecosystem.

    Project Detailsโ€‹

    We will first describe the architecture of the current system, and then the improvements and additions we plan to implement in the course of this grant.

    Architecture Overviewโ€‹

    Signet's architecture provides the ability to manage offchain enterprise workflows along with supporting data like address books in a secure manner. With access controls and the ability to self host the instance, clients can choose the level of security and privacy for their implementation.

    architecture

    Our system is designed around the idea that a multisig unit is a keyless any proxy controlled by a Substrate multisig. We use a magic link system that encodes the proxy address and the member addresses of the multisig, which can then be shared with other signers to import it into their instance of Signet. The frontend is built in React and Typescript.

    Offchain data used to support Enterprise Workflows are stored in a Postgres Database via Hasura, which offers at least 2 levels of authorisation. Requests to access data in the database are authorised using a combination of on-chain and off-chain data to satisfy various business needs, followed by role based access control built into Hasura. Access is restricted so that the Hasura server is the only service that can call the database.

    We use Sign in with Substrate (SIWS) to authenticate users. This allows our backend to confirm that whoever claims to own an address and wants resources relevant to that address actually owns the address and is able to sign a challenge message to provide proof. SIWS has been created specifically for Signet, and is run in a nodejs sidecar.

    Signet is designed in a modular way, so that specific workflows or extrinsics can be have a custom UI that enables non-technical users to perform blockchain actions.

    The initial version of Signet was developed as part of a Polkadot Treasury Proposal and aimed at DAOs and smaller teams in Polkadot. We have since decided to focus on larger enterprises who require more complex workflows and risk mitigation.

    Key Focus Areasโ€‹

    For the purpose of this grant, we are looking to build on top of the work and architecture presented above and address the following two issues:

    1. No standard for Sign in with Substrate: While other projects have built custom solutions for logging into an app using Substrate, there are currently no reusable components to make it easy for developers to build apps and services on top of Substrate login.
    2. Improve existing UX for Selecting Validators: Validator selection is currently difficult and error prone, and users have no easy way to double-check the addresses they are assigning in the process.

    The following diagram shows Signet as it is being built out currently (in black), as well as the additions enabled by this grant (in green).

    capabilities

    SIWS is a building block towards a shared address book for multisigs/organizations, which can enable migration of shared enterprise information from computer to computer or authorized person to authorized person, as well as allows for easier selection of validator addresses for all signers to leverage and is a key part of improving the experience of using Substrate-based proxy-multisigs.

    Ecosystem Fitโ€‹

    The project is built on Substrate, using Substrate native features. The goal of the project is to enable entities (corporations, asset managers, web3 companies etc.) to feel comfortable enough operationally to manage a significant amount of assets on Substrate.

    Target Userโ€‹

    The target audience is enterprises and larger organizations who require workflows and risk management in order to be comfortable to deploy capital into the Polkadot ecosystem. This may include enterprises already operating on-chain in Substrate, enterprises with a large web2 footprint, including, potentially, customers of Mythical Games, Aventus, Peaq, Energy Web, etc, or more traditional organizations evaluating moving into Substrate including, potentially, Deloitte, Sony or Toyota. Signet would allow C-Levels and Finance/Operations departments at these types of companies to feel comfortable integrating blockchain into their workflows.

    Similar Projectsโ€‹

    There are a number of multisig front-ends or multisigs in development in the Polkadot ecosystem, including: Multix, PolkaSafe, Saturn. While ostensibly there is an overlap in functionality related to being a multisig, Signet is designed to sit at a layer above the multisig and aimed at a different target audience:

    1. Signet is designed to be self-hostable to enable an organization to manage it's own off-chain data and workflows in a way that meets it's internal devops and security needs.
    2. Signet's main value-add is not simply to provide a more friendly multisig UX, but rather to enable an organization to implement their own workflows on top of the multisig process. It's likely that these workflows require, at least at this time, off-chain operations and data storage that enhance the underlying blockchain.
    3. Signet's direction is to become a platform that integrates with different multisig front-ends or multisig pallets, rather than competing with them.

    Regarding Sign in With Substrate, there are a few projects that have implemented bespoke methods of logging in with a Substrate keypair to their own dapps, however we believe these fall short of the user-friendly and developer-friendly needs to truly function as a component that can be reused, as well as to grow an ecosystem of apps and services on top of a Substrate login:

    • The messages signed are unintelligble bytes, rather than human readable messages
    • The format of the login has not been standardized/structured to enable implementation into wallets/signers
    • The component(s) are not packaged, available and deployable in developer-friendly ways
    • The documentation doesn't exist that enables a developer to implement the sign-in functionality.

    Regarding managing a staking position, most institutional holders still use Polkadot.js, as it is the most longstanding and trusted tool, though due to a confuing UI, using it can easily lead to confusion or potential mistakes.

    Alternate methods of managing staking positions, such as Polkadot Staking Dashboard, are available to users, but they are focused on retail usage at the current time, and do not support the more complex needs of institutional or enterprise users.

    Conversations with W3Fโ€‹

    We have spoken briefly to David Hawig at the W3F to introduce the project, as well as to inquire about the W3F efforts to bring credit card processing/settlement to Polkadot (ISO20022, ISO8583). We also discussed the difficulty of staking (e.g. nominating or changing validators) today using Polkadot.js, especially as complex proxy and multisig structures come into play, which has informed this proposal.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    • Total Estimated Duration: 1 month
    • Full-Time Equivalent (FTE): 1,5 FTE
    • Total Costs: 26,400 USDC

    Talisman uses a blended rate for grants and proposals (see previously funded initiatives here, here and here). This allows us to ensure the needed resources can be allocated to product development as well as running the company, including, as needed, to supplement the FTEs with the expertise of senior Talisman members as needed, with the goal of executing at our product quality standards. In this case, due to the value added program provided by the W3F and to show our support for the W3F mission in helping to bring new products and technologies into existence, we are applying a reduced rate.

    Milestone 1 โ€” Sign in with Substrate (SIWS) Releaseโ€‹

    We have modeled our substrate login functionality (Sign in with Substrate - SIWS) on Sign in with Ethererum, and we hope this can catalyze the development of applications that build upon Substrate keypairs. We will extract the work that we have in integrating the login with Signet into an independent package that can be integrated by any team, provide website and documentation around the package, and set this on the road to becoming a standard.

    Authenticating a user with a Substrate key was initially developed as part of Signet, however we believe it should have a number of improvements before it can be released as a service or component ready for use by third parties:

    1. The version as implemented uses the JSON format with minimal payload data and only supports the server-side nonce check. We should augment this by supporting a string field that can contain information such as a welcome message or the terms of service of the dapp.
    2. We will implement both text and JSON formats for the message to be signed, for both the presentation of the message client-side, and verification of the message server-side.
    3. We will implement a field for expressing time validity/expiration of the signature, as well as the corresponding server-side check.

    We will also create an example โ€œboilerplateโ€ NextJS Dapp that integrates SIWS.

    On the frontend: We will prepare 3 pages to demonstrate how SIWS works can protect an appโ€™s data:

    • Sign in page with SIWS button to trigger sign in flow
    • Signed in page that fetches a secret message from backend
    • Unauthorized page that does not have access to get the secret message.

    On the backend: We expose 3 API endpoints:

    • /api/nonce: To generate a nonce for user to sign on the frontend
    • /api/verify: To verify that the signed message is valid and issue a JWT
    • /api/secret: A protected endpoint that returns a secret text only if the JWT is valid

    The demo app will be in a configuration that enables developers to easily deploy it on Vercel.

    Weโ€™d like to address these improvements in the course of packaging Sign in With Substrate (SIWS) as a releasable component.

    Milestone 2 โ€” Signet Staking Module Improvements re: Validator Selection & Rotation UIโ€‹

    We would like to improve the use cases (a.k.a. modules) enabled by Signet, by enabling user-friendly validator selection. We believe this is a core use cases for organizational and institutional multisigs in Polkadot/Kusama, and would be a foundational aspect of workflows to be built out in future releases. Currently selecting or rotating validators requires complex copy and pasting actions to assemble Polkadot.js Apps extrinsics, and we believe a purpose-built front end would alleviate the pain in performing the following actions:

    1. Selection/rotation of validators for a nomination pool where the nomination pool controller is a pure proxy controlled by a multisig
    2. Selection/rotation of validators by the stash, where the stash is a pure proxy controlled by a multisig
    3. Selection/rotation of validators where the staking proxy is a pure proxy controlled by a multisig.

    Future Plansโ€‹

    Talisman initially embarked on the Signet project in order to "scratch its own itch" and bring it's user-friendly approach to multisigs. Signet has grown into its own project focused on larger enterprises and organizations, with the mission to build out a platform that enables institutional liquidity to flow in Polkadot.

    For SIWS, we are interested in promoting wider adoption, as we believe that it can unlock a use cases where off-chain data is combined with on-chain data, and this may span enterprise apps/integrations or even consumer apps or games. After this grant, we will take a look at how to garner support/adoption of the technology, and collaborate with others in the ecosystem to put this on the path to becoming a standard.

    Polkadot Spending Proposal: Business-Friendly Polkadot Multisig

    This proposal is for a business-friendly multisig frontend to lower the difficulty for teams and businesses when running their financial operations on Polkadot. Teams currently face many difficulties when trying to perform these operations, risking mistakes along the way, and leading them to choose convenience over security. We will apply Talismanโ€™s UX and design philosophy to create improvements for standard workflows for Polkadot multisig usage (based on the current multisig pallet), and eventually integrate upgrades when improvements to the multisig pallet itself are available.

    [Milestone 2 Delivery](https://github.com/w3f/Grant-Milestone-Delivery/pull/742)

    Overviewโ€‹

    From our previous grants we have built:

    • A Wasm contracts explorer that supports smart contracts deployed on pallet-contracts
    • A verifier service that verifies, through reproducible builds, the source code files for a specific on-chain code hash.

    In this grant, we intend to expand Sirato to support essential base data such as blocks, extrinsics and system events.

    Project Detailsโ€‹

    In our current architecture, there are several components:

    • Squid Archive (built on the Subsquid framework): the squid archive connects to the Substrate network node and indexes base data such as blocks and extrinsics, exposing a GraphQL API
    • Squid Processor (built on Subsquid framework): the squid processor ingests data from the squid archive, filtering and transforming the relevant data to the data models for the Explorer. Currently, our squid processor is focused on Wasm contract data from pallet-contracts. The squid processor exposes a GraphQL API.
    • Explorer UI: The explorer UI is made up of a set of composable components that consumes the API of the Squid processor and renders the web application.

    The below diagram illustrates the high-level architecture and how the components interact with each other:

    Current Architecture

    In this grant, we will add data handlers and data models for the base data. Since the Squid Archive directly exposes the network base data of blocks and extrinsics, we will use the GraphQL API of the squid archive in the UI to retrieve this data.

    Network Data Supportโ€‹

    The Squid Archive already exposes blocks, extrinsics and events data through its GraphQL API. We will consume this API from the explorer UI and build the components to show:

    • Blocks list
    • Extrinsics list
    • Block page: contains block details and all extrinsics and events included in this block
    • Extrinsics page: contains extrinsic details and all events emitted from the extrinsic

    Mock-upsโ€‹

    Mock up of how an extrinsic page will look:

    Extrinsic Page

    Technology Stackโ€‹

    We plan to build on top of our current explorer, so we will continue using the same technology stack:

    • Subsquid Framework, with Typescript, for data processing.
    • React.js and Tailwindcss for the UI

    Out of Scopeโ€‹

    Due to time and resource constraints, we will leave the following items for future development:

    • Additional query endpoints for interrogating the contract registry
    • The ability to interact directly with verified smart contracts

    Ecosystem Fitโ€‹

    There is currently a lack of high-quality open-source explorers for smart contract networks in the Substrate ecosystem. Polkadot.js is the de facto explorer and it is very modular and flexible. However, it was designed more for development and lacks the ability to filter, sort and search through data on the network. In the space of user-facing explorers, Subscan is currently the most popular solution and has the most comprehensive support for Substrate pallets. On the other hand, Subscan is mostly close-sourced and introduces an economic entry barrier for new networks.

    This dominance by Subscan is something that has been highlighted recently during an in-depth discussion on the Polkadot Forum.

    While a number of open-source alternatives have emerged, none of them have support for smart contracts. In our previous grants, we have expanded the open-source explorer offerings to include WASM contracts on Substrate. At the same time, we also want to provide the essential base data like blocks and extrinsics so that smart contract networks can have a feature-complete explorer at their fingertips.

    Future Plansโ€‹

    We plan to add open-source support to other popular Substrate pallets in the future. Some interesting pallets we are considering are assets and XCM related pallets, to be able to track asset movements across the DotSama networks.

    The Frontier EVM and EVM+ pallet by Acala are also valuable addition to the ecosystem that we wish to support at some point. On top of that, we also plan to add some proprietary modules for the explorer to be able to sustain our growth long-term. Our goal is to provide a full-fledged open-core explorer with comprehensive data and intuitive UI that networks can customise to their needs.

    Besides the core explorer, we also want to expand the functionality of our ink! verifier service. Right now, it only supports the verification and metadata hosting of ink! smart contracts.

    Our goal is to support any WASM smart contracts and evolve the service to a multi-VM metadata registry that can scale up to cater for the entire Substrate and DotSama ecosystems.

    Project Overview ๐Ÿ“„โ€‹

    The SkyeKiwi Protocol is a generic, efficient and customizable secret sharing protocol for end-users and blockchain nodes.

    Project Detailsโ€‹

    The SkyeKiwi Protocol hides secrets under bright day lights. It is designed to be generalized useable blockchain library to package/manage encrypted content on blockchain. We designed it to be capable of efficiently processing a few bytes to GB size of secrets. It's a series of cryptographic process with help of storage network and smart contract/Substrate runtime pallet.

    The process can be graphed as:

    Group 1

    It will take in a two inputs: a byte stream wrapped under the File API, an EncryptionSchema that outlines the sharing behavior and an optional SealingKey and any related blockchain identity seed/signer.

    The high level wrapper of the SkyeKiwi Protocol exposes four APIs: upstream, donwstream, updateEncryptionSchema and verifyProofOfAccess. And will be released in two phase:

    1. Phase One - PoC Phase: Connects to a smart contract of a Substrate style WASM smart contract enabled blockchain; the Crust Network for storage; Public IPFS Pin Service & Gateways, with a SkyeKiwi ran IPFS Cluster as backup IPFS nodes.
    2. Phase Two: Connects to the SkyeKiwi Network pallet-secrets instead of a smart contract for general secrets registry; the Crust Network for storage; Public IPFS Pin Service & temporary IPFS nodes from the Crust Network ecosystem solutions.

    Usage Example on Node.js/Browser:

    const mnemonic = process.env.SEED_PHRASE
    const blockchain = new SkyeKiwi.Blockchain(
      // seed phrase
      mnemonic,
      // contract address
      '3cNizgEgkjB8TKm8FGJD3mtcxNTwBRxWrCwa77rNTq3WaZsM',
      // contract instance endpoint
      'wss://jupiter-poa.elara.patract.io',
      // storage network endpoint
      'wss://rocky-api.crust.network/',
    )

    const encryptionSchema = new SkyeKiwi.EncryptionSchema({
      numOfShares: 2, 
      threshold: 2, 
      author: author, 
      unencryptedPieceCount: 1
    })
    encryptionSchema.addMember(author, 1)

    const key = new SkyeKiwi.Seal({
      encryptionSchema: encryptionSchema, 
      seed: mnemonic
    })

    // upstream the file, it take two major actions: 
    // upload files to the Crust Network & Write to a smart contract to generate a vaultId
    await SkyeKiwi.Driver.upstream({
      file: fileHandle[0].file,
      seal: key,
      blockchain: blockchain
    })
    const stream = fs.createWriteStream(outputPath, {flags: 'a'})
    await SkyeKiwi.Driver.downstream({
      vaultId: vaultId,
      blockchain: blockchain,
      keys: [key1, key2 ... ], // private key of recipeints
      writeStream: stream,
    })
    // upon finishing, the encryptionSchema will be updated
    await SkyeKiwi.Driver.updateEncryptionSchema({
      vaultId: vaultId,
      newEncryptionSchema: encryptionSchema,
      seed: mnemonic,
      keys: [key1, key2 ... ], // private key of recipeints
      blockchain: blockchain
    })

    Ecosystem Fitโ€‹

    The SkyeKiwi Protocol has a wide applicable areas. It's a generalized and customizable solution. For instance:

    • Extend the NFT landscape to introduce NFTs with concealed content and strict access control of the content
    • Contract signature, build a decentralized contract signing platform, a DocuSign alternative.

    Moreover, SkyeKiwi will take the SkyeKiwi Protocol and built into the SkyeKiwi Network featuring concealed smart contract execution and secret processing. Where the SkyeKiwi Protocol is the schema used to communicate between blockchain nodes and between end-users to blockchain nodes.

    We will build a Substrate based blockchain with the SkyeKiwi Protocol. The blockchain is gonna feature:

    1. Three registry: registry for SecretKeeper Nodes (TEE enabled nodes who keep a secret and process state transition functions on secrets), registry for general secrets (included in Milestone 2), registry for encrypted states (encrypted states are secrets that represents the state of secret contracts, the registry will mark the lazy execution position, checkpoint status of these states, and which nodes are processing the secrets).
    2. Two Rotation: the small rotation - on par with the session key rotation of Substrate, the big rotation - rotate the sealing key of the encrypted states in TEE enclaves, and package the current states of the secret with the SkyeKiwi Protocol and publish it to the registry
    3. One Lazy Execution Queue: an append-only log that records all transactions happened on a secrets, that can be subscribed by any nodes with access to the secret.

    The blockchain (SkyeKiwi Network) will be able to execute concealed smart contract executions.

    Project Overview ๐Ÿ“„โ€‹

    SkyePass is a decentralized and customizable identity management software. On the surface, it is a decentralized, open source and modern password manager.

    Product Detailsโ€‹

    As a long-term password manager software user myself, I have been really frustrated of the services like LastPass, 1Password for either lack of functionalities or the idea of storing ones entire digital identity on their corporate servers. Existing open-source solutions are too technically complicated to use.

    At the very basis of it, a password manager is no more than an encrypted database, an APP and a browser extension to interact with the database.

    Therefore, our team create a new password manger software that has pretty and intuitive UI/UX, fully decentralized (i.e. our team own no backend servers) and hackable by providing an open API for people to develop extensions with.

    Users who signup will first create a blockchain wallet and have the mnemonic (and a master password) as their sole identity credentials (pretty standard blockchain wallet stuff). Later, each database instance is called a vault (standard name for all password managers) and they are light-weight file based databases (lowDB seems to be a great choice). User can be given options to choose the encryption behavior of their database. By default, the vault will be split into some pieces with a Shamir's secret sharing mechanism.

    For instance, for a simplest sharing schema, when the vault is created to be shared with 2 other family members, the vault will be split into 4 parts (we call them horcrux, for those who do not know the Harry Potter reference ) with a minimum quorum of 2 to be decrypted. One piece will be sent to IPFS without encryption, the other 3 pieces will be encrypted by each member's public key and be sent to IPFS. An NFT will be minted for the owner. The ID of the NFT will be the vault ID and the NFT's URI will be a metadata piece that only the owner can change as exampled below:

    {
        "pieces": 4,
        "quorum": 2,
        "nounce": 18,
        "owner": "5Ef9ES1SLQZU4KucGsjvs8qexvppQFmDgHiqoqVptJ9nZDeu",
        "members": [
            "5EKj6S1SLQZU4KucGsjvs8qexvppQFmDgHiqsdsdtJ9nZ123",
            "5EJK1S1SLQZjkLKucGsjvs8qekdjpQFmDgHiqoqVptJ9nZ978"
        ],
        "unencrypted_cid": "QmaTX2v2QuwkQvEERw17w2xACcr2WZhy9t3NAEPBjvqPSX",
        "encrypted_cids": [
            {
                "cid":       "QmaTX2v2QuwkQvEERw17w2xACcr2WZhy9t3NAEPBjvqPSX",
                "member": "5EKj6S1SLQZU4KucGsjvs8qexvppQFmDgHiqsdsdtJ9nZ123"
            },{
                "cid":       "QmaTX2v2QuwkQvEERw17w2xACcr2WZhy9t3NAEPBjvqPSX",
                "member": "5EJK1S1SLQZjkLKucGsjvs8qekdjpQFmDgHiqoqVptJ9nZ978"
            }, {
                "cid":       "QmaTX2v2QuwkQvEERw17w2xACcr2WZhy9t3NAEPBjvqPSX",
                "member": "5Ef9ES1SLQZU4KucGsjvs8qexvppQFmDgHiqoqVptJ9nZDeu"
         }]
    }

    The reason why we design such mechanism serves 3 purposes.

    1. Reserve the capacity for advanced users to create more complicated sharing schema.
      • For instance, a user can create a vault and assign trustee to take over one's estate when the user passes away. The user can split the vault to 5 horcrux and set the minimum decryption quorum to 3. 2 pieces encrypted with the user's own public key, 1 piece encrypted with a trustee A's public key, 1 piece encrypted with another trustee B's public key and 1 last piece to the user's lawyer. In event of death, A and B can go to the lawyer and decrypt the vault and inherit the user's digital identities.
      • A team can create a vault that requires 2 members to decrypt a vault, or require the owner's piece to decrypt a vault etc.
    2. Because the historical metadata states are all stored on the blockchain, it is not hard to rebuild the change history of the vault.
    3. Make it easier to check the integrity of the vault and recover the vault.
    4. Leave the option open for future commercial projects to offer zero-knowledge vault backup service.

    To manage access for users, we assume two common roles: write and read and, of course, owner. Because each time when the database is updated (i.e. new password saved), the IPFS CID will be updated, managing access is easy. The owner can add the member's address to be approved to change the URI in the smart contract and be responsible to update all CIDs when a client is updating the database. While those who have a horcrux but not in the approved list in the smart contract, they cannot update the database because they cannot update the metadata.

    So far, we have discussed a system to securely create, share and manage a minimalism decentralized file-based database. Our team believe there are more we can do with the database file itself and that's why we are calling SkyePass hackable. If we think about blockchain wallet applications, they are web applications that store some private keys and call APIs like Web3.js. Taking inspiration from Ledger, we believe if we expose some APIs for developers to make extensions(like the idea of Applications for Ledger), we can make a password manager infinitely interesting. Because the vault is shareable to others, users can share a whole workspace to others will all sensitive information included. These extensions can be made both in a desktop applications or a browser extension.

    Some ideas we have had so far:

    • Crypto Wallet: shared hot wallet. The owner of the vault can install an Ethereum extension and store the private key with it. And, of course, DApp browsers.
    • SSH Login Tool: a whole team can share login credential to their server effortlessly.
    • Shared Phone Number: a shared Google account that registered on Google Voice can be stored, and the whole family can receive verification code for services.

    Password Manager & an Identity Management Solutionโ€‹

    Based on some thinking of the basis nature of NFTs. We believe that a password manager is an ideal medium to deliver tokenized digital identities. Therefore, we think each username-password-OTP combination as an atomic token, a vault as a collection of these identities, and an extension as a service injected with an identity.

    • If we assume all identity tokens have two states: "public identity" or "private identity". A public handle is the public identity of a user. (i.e. a twitter handler, a Github handle or a Venmo handle etc. ) Therefore, we are building a solution to link to one's public off-chain profiles. Also, we can implement a ENS-like or @username style handle system.
    • Therefore, simple sharing behavior (i.e. share my spotify account to my girlfriend) can take two forms: if she has an account with this password manager, simple @her, set some rules for using this password(or not) and press share. If she has not, a one time sharing link will be sent, her browser will generate an ephemeral key pair, and that ephemeral key pair will be used to encrypted the entry and send the encrypted password entry over and make it self-destruct soon.
    • For teams or families, they are using a shared identity. They can link their profiles and get a handle like @team, while the team will use some secret sharing schema for privilege management.

    For more on this, please refer to Future Plan/Integrated Identity Solution section.

    Ecosystem Fitโ€‹

    I don't think there are anything like SkyePass so far, both within the Substrate community or all blockchain communities. The reason that Substrate will be an ideal platform for SkyePass is because the flexibility the framework offers. We plan to deploy 4 smart contracts:

    • Contract 1: A NFT contract that issues an NFT token for vault creator, store metadata of the vault and manage permission to update the vault. (the vault metadata contract)

    • Contract 2: A NFT contract that generate an NFT token that represents an atomic digital identity to users (the atomic digital identity contract)

    • Contract 3: A generalized handle system (an ENS-like system) on a Substrate-based chain that issue user handle ownership NFTs (the substrate identity handle contract)

    • Contract 4: An identity control smart contract that verify and store off-chain user handle(s), in compliment to the substrate identity handle contract (the off-chain identity linkage contract)

    From all smart contract platforms, we choose the Substrate stack for development because:

    • When more customizations are needed, we won't be limited by the platform. The option to develop a parachain is still available.
    • Because these identity management smart contract is designed to be more generalized, we have the option to deploy them on different chain. For instance, we can deploy contract 1 and 2 to a faster/less secure/low tx cost focused parachain. While, contract 3 & 4 to a secure and relatively more decentralized parachain. Most likely we will not mess with Bridging of the Substrate stack but the option is still open for future.

    For extensions: we plan to host a Github public repo as described in Milestone 2

    Future Plansโ€‹

    We do plan to build a for-profit business and seek equity investments, but we believe that a good password manager should be a common goods.

    For the core password managerโ€‹

    For local usage, that means no syncing between devices, no sharing with others, we think it would be absolutely ridiculous to charge people for that, because it basically does not cost us anything. However, for other use cases, on a public V1.0 launch, there can be cost related to IPFS storages and smart contract calls, but it is gonna be way cheaper than any other commercial products. I think it would be safe to assume a cost of \$2/year for one user with extra-heavy usage. For a team of 10 people, 1Password will charge (\$7.99 X 12 months X 10 users) \$960 per year. SkyePass will change this charging schema.We want to make the pricing as transparent as possible.

    When a user, Alex, created a wallet/account and choose to go for "premium features" (i.e. syncing between devices, sharing with others etc.). We want to ditch the idea of "Alex's account at SkyePass" but to "Alex's account on a generic blockchain". Alex can fund her account either by transferring some funds from Coinbase or other crypto wallets, or we will hook up a credit card to crypto portal (like MoonPay). We are going to give Alex a simple estimation calculator of how much she would need to top-up per year based on how many devices of vaults she plans to create and share. Usually, for a typical user (add in 300 items, password, notes or credit cards, one vault for herself, one vault for the family and one vault for work), we would recommend somewhere about \$5 per year compare to a $40 bill I pay for a commercial alternative. A percentage (somewhere between 20% to 40%)of the inbounding funds will be taken to form a treasury. And, of course, we will show Alex how much she can save compare to commercial options. Alex has complete control over her account. She can send out the funds she holds other wallets when she wants. When she is sharing a vault with others, she can choose to send funds to other's account if she allows them to make changes to the vault.(Just in the same way when a team leader of a team handles all bills for a SaaS product).

    In summary, we are giving the freedom back to our users and let them decide how they want to pay. We will design UX to make managing funds really easy like a commercial alternative.

    Integrated Identity Solutionโ€‹

    1. We plan to build an auction market for user handle on a Substrate-based public chain. (refer above in More Potential For a Password Manager)
    2. We plan to build a market for trading digital identities.
    3. We plan to offer the identity solution in a consulting package for business teams.

    Hardware Wallet Integrationโ€‹

    We can also create a special version of SkyePass (or a special login method to use hardware wallet) to support only vault creation from hardware wallet.

    Meta Transactionโ€‹

    One of the main reason that we choose Substrate/Polkadot is because we can choose a suitable chain to interact with smart contract calls fast and cheap. The option to develop commercial meta transaction or state channel solutions on Polkadot is still open for consideration.

    Backup/Secret Keeping Nodesโ€‹

    Because we are building a Shamir secret sharing mechanism at our very core encryption schema, we can explore the idea of providing an optional, commercial and centralized backup nodes.

    Marketplaceโ€‹

    We allow and encourage our community members to build paid extensions on top of our APIs. One idea can be a subscription-based password watchtower service and like all platforms, we will take a percentage of the proceeding to the treasury.

    Treasuryโ€‹

    Treasury is built for those who contributes to the community: those who translate documentations, those who build extensions and those who contribute to the core code base. SkyeKiwi team will permanently hold 29% voting rights in decisions and 3 veto rights per calendar year, partners before the official launch will also be granted 20% voting rights. And we leave the rest to all other treasury contributors proportionally. These numbers or proposals are not final. We still have a lot to figure out.

    Project Overview ๐Ÿ“„โ€‹

    If this application is in response to an RFP, please indicate this on the first line of this section.

    If this is an application for a follow-up grant (the continuation of an earlier, successful W3F grant), please provide name and/or pull request of said grant on the first line of this section.

    Overviewโ€‹

    Our intention is to build the initial parts needed for an integration with Skynet, allowing Substrate developers to make use of decentralized off-chain storage from any project using FRAME.

    Skynet is a decentralized storage and web application platform built to use the Sia blockchain network for storage, but in a way that's accessible via the web and available to anyone, without concerning themselves with cryptocurrencies or special software. Skynet provides hosting of robust web-app frontends and storage of application data in a way where users retain control over their data and application data is interoperable between applications.

    Off-chain storage is an important problem to solve for blockchain applications, and Skynet meets storage needs well on several fronts by providing:

    • a decentralized architecture matching the ethos of blockchains themselves
    • strong, cryptographic guarantees on immutable data
    • mutable data using private keys for write access
    • portals used to access data, allowing for either managed access or running your own software. (With managed access, users and developers don't have to integrate another cryptocurrency running on a separate chain into their architecture.)
    • equal access to Skynet no matter what portal is used or how it is accessed

    Our team wants to take on this project to expand the possibilities of what can be done with web3 applications and decentralized storage.

    At this point, we have a JS SDK to easily expose Skynet in the browser to users, who can upload files and then store the unique URI (skylink) on-chain. Later, those can be retrieved and easily downloaded in the browser. We'd love to see developers building applications where blockchains themselves can interact more deeply with Skynet, writing data to Skynet, either for later access or for consumption by other web applications.

    Project Detailsโ€‹

    In its final form, the Skynet Substrate SDK made for use in Off-chain Worker Pallets would allow projects built with Substrate FRAME to access any Skynet Portal on the network using off-chain workers in order to do the following on Skynet:

    • Upload a file or directory and return the skylink for use by the runtime
    • Download a skyfile to storage or for use by runtime
    • Registry Read: read from Skynet's mutable data layer using public keys
    • Registry Write: write to mutable storage, authenticated by signing using a private key
    • Support any Skynet portal and portal account
    • Support v2 Skylink compatability
    • Interact with mutable SkyDB and MySky files
    • Data Verification for all interactions with a portal, using storage proofs from the Sia network.
    • Subscribing to registry entry changes (pending future Substrate development of long-running off-chain worker processes).

    Communication with portals happens by utilizing portal HTTP APIs along with additional processing and cryptography on the client-side. Although Skynet interaction can appear to be merely REST-styled API requests, certain cryptographic tools are needed to 1) created well-formed requests and 2) verify the cryptographic proofs and signatures returned alongside HTTP responses. Without this additional tooling that requires "client-side" processing, most of Skynet's power is cutoff from the application.

    In addition to this, decentralization is at the core of Skynet's ethos, so the SDK must account for additional complexities over interacting with portal APIs that might not exist for a traditional API endpoint, including supporting portal accounts (similar to authorization), dealing with not-shared-in-common portals (where nodes could supply their own portal URL and API key), and porting our Skynet utility libraries to Rust to ensure full inoperability with browser javascript applications and creating and signing items like registry entries to enable SkyDB and Skylink v2 (allowing content updating for a constant URL which can point to immutable skyfiles). For greater clarity and flexibility, we will separate the example pallet codebase from the SDK library of action and helper utils.

    To be more specific on the functionality needing to be built out in Milestone 1:

    Note: This work is implementing interaction with a pre-existing protocol, so much of the work will be porting code from our Javascript SDK to Rust in a way that feels ergonomic for Substrate developers.

    Authentication & Portal Preference for HTTP Requestsโ€‹

    • All below actions requiring interaction with a Skynet portal should be assumed to be interacting only with the preferred portal and using an authentication mechanism. (Currently we support only encrypted JWTs, but may extend to API keys too.)
    • For example, repinning Skylinks requires a simple HTTP request with optional authentication.

    Immutable Skyfilesโ€‹

    • Skyfile downloads are just HTTP GET requests.
    • Skyfile uploads come in 2 varieties:
      • Small Files: Simple HTTP POST requests that return a skylink from the portal
      • Large Files: Orchestrated HTTP requests implementing the tus protocol for increasing reliability by retrying failed chunks.

    Mutable Registry Entriesโ€‹

    • Registry entries have a specific structure including a public key, data key (which together identify it for lookup), a revision number, data (limited to 70 bytes), and a signature signing the aforementioned using the public key's corresponding secret key.
    • Reading registry entries involves making an HTTP GET request, then verifying the signature against the data (Key pairs and signatures all using ed25519).
    • Writing registry entries involves creating a registry entry (getting the revision number can be done by first reading, or trusting you know the correct revision), and then signing the entry before making a POST request to the portal.
    • Registry entries have a complicated concurrency model, so attention will need to be given to revision number usage and tracking.
    • Registry entries are the core mutable primative for the rest of Skynet, including MySky, SkyDB, and Skylinks v2. The 70 bytes can be used to create custom data structures and is enough space to hold 2 Skylinks.
    • For creating a Skylink v2, this is a coordination of getting or creating a Skylink to point at, converting the link from Base64 to a byte array, and writing this to a registry entry. This data field then acts like a pointer in the Skylink v2.
    • Then a hash of the public key and data key is taken and encoded into a skylink format (combining with a version number) before encoding to Base64 to generate the v2 Skylink.
    • Reading a Skylink v2 involves a GET request, which returns the data from the pointed to immutable Skylink (if the Skylink v2 points to another Skylink v2, if acts recursively until immutable file is resolved). The portal also returns a "proof" containing the chain of registry entries (each a Skylink v2) that need their signatures verified.

    For this grant, we seek the support of the Web3 Foundation for doing an initial build-out of Skynet functionality. The Skynet Labs team (formerly Nebulous, creators of the Sia blockchain network) have extensive experience in blockchain development, but have much less experience in Rust and the Polkadot ecosystems. We would view this as an opportunity to build out support for many of the Skynet primitives and utility functions while working to find the most developer friendly way of exposing those to applications building with Substrate.

    For more information on Skynet and our SDKs, see our support guide and our SDK documentation.

    Ecosystem Fitโ€‹

    The most similar project in the ecosystem that we are aware of is the offchain:ipfs fork of Substrate that implements an ipfs node in Rust along with an example pallet.

    IPFS has many differences in performance, ease-of-use, availability and infrastructure as compared to Skynet. The most critical to this conversation is that Skynet Web Portal take care of much of the overhead that an IPFS node would, but without equal data verifiability guarentees. Because of this, we do not intend to need to make modifications to Substrate core for integration, instead working from the perspective of a pallet, allowing for easier maintenance and community up-take in the long term.

    Some use cases where we believe Skynet will be useful for Substrate devs:

    • Chains where interaction focuses on client-side web apps
    • Off-chain storage for NFTs
    • On-chain referencing of user-generated-content
    • Indirect communication for chain-external data (where another service can publish to skynet, to be consumed by the off-chain worker)
    • Persistance of runtime data that isn't saved to storage
    • Off-chain publishing of on-chain data

    Future Milestone - Skynet Immutable Off-Chain Storage Pallet (Mutable Data Functionality)โ€‹

    We intend to take the lessons learned from the first version of this pallet and extend Skynet functionality according to the needs of developers. What follows are some steps we would look to take outside of the scope of this grant.

    NumberDeliverableSpecification
    1.Skynet Substrate SDK for Off-Chain Worker Pallet (SkyDB and MySky File support)We will extend the SDK from milestone 1 to interact with the primatives built on Skynet's registry. This mutable storage layer acts as key-value database from which SkyDB and MySky files are constructed. This allows getting and setting arbitrary data and pointing to JSON files, encrypted files, and arbitrary skyfiles pointed to by consistent MySky file paths. These use public/private key combinations for access-control. This will also contain functionality for generating decryption and derivation keys that are interoperable with Skynet's MySky SDK.
    2.Skynet Substrate SDK for Off-Chain Worker Pallet (Verification)We will extend the SDK from milestone 1 to allow for two important features: Verification of storage proofs for full end-to-end trustless infrastructure, and, pending Substrate's addition of long-running off-chain workers, subscribing to changes of SkyDB entries using Websockets. If this functionality is not yet in place for FRAME, we hope to work with core developers to prepare for implementing this functionality when the feature becomes available.

    Community engagementโ€‹

    Skynet has a very active developer community, and we'll be sure to create various content around the integration, including promotional write-ups and a highlight video as part of our SiaTV YouTube content.

    We engage general audiences and developer audiences with our outreach media, and we'd include content for each audience.

    Future Plansโ€‹

    Skynet Labs will continue to develop Skynet by furthering integrations with blockchain projects needing decentralized, off-chain storage and front-end hosting, while also supporting client-facing applications that fall outside of blockchain programming. Our goal is that the data for these use-cases becomes increasingly interoperable and empowers users to have control over their data. Our medium-term plans include a robust monetization ecosystem that builds on our client-side, fully decentralized identity solution MySky.

    02/25/2022โ€‹

    We grossly underestimated the number of blockers and competing priorities we'd encounter as a team, and the timeline has now been exceeded by several months. We are ready to submit our work, and will do so soon.

    As we better understood the ecosystem, we realized that a library for using Skynet in an off-chain worker was much more flexible for developing an application off-chain worker than was a proper pallet. As part of our deliverables, we now include the SDK library code skynet-substrate, along with a substrate example off-chain worker and front-end showing how to use various features of the SDK.

    This amendment also updates our company name, URL, and payout address.

    We could talk about the bidding/contributing strategy. It's really flexible. If anyone got more ideas. I can integrate them into the program.

    I have talked to some teams few months ago. Because they ask me what script did I use during the bidding. Can I share it? Actually, I set some proxies accounts and share them with my team members. Then we watch the auction manually. If there is a new winner we could bid immediately.

    As I said before, there is even an empty auction in Kusama. This is not friendly and not good for the ecosystem. So, I decided to develop this. And I think it is valuable.

    Social Recovery Wallet

    • Team Name: Hypha Hashed Partners
    • Payment Address: bc1q7axtazzhsdttextp0qspueaagv4pgfm5l9ne64 (BTC)
    • Level: 2

    Project Overview ๐Ÿ“„โ€‹

    Proposal for the RFP titled Social Recovery Wallet.

    Overviewโ€‹

    We develop Flutter wallets. We have experience developing social recovery wallets in Flutter. We develop the SEEDS Light wallet, found at the Android store and the iOS store.

    We have implemented social recovery in that Flutter wallet. It operates on Telos.

    Project Detailsโ€‹

    Recovery Screen Mockups / Descriptionsโ€‹

    These screens include:

    • Splash and main screen (mockup)
    image
    • Set / Remove social recovery accounts ("guardians")
    image
    • Recover account screens - generate recovery link to send to guardians
    image
    • Recovery wait countdown screen
    image
    • Process recovery URL to recover someone's account (see video of existig wallet)
    • Cancel recovery - prevent maliciuous actors (see video of existing wallet)

    The process overall will look similar to the existing Seeds Light Wallet process

    See the video here https://www.youtube.com/watch?v=Vpb8IbHvcNU

    To make recovery easy for a user, we provide a deep link users can share with their guardians.

    To make recovery more difficult to attack, we require the user to send the link to their recoverers outside the wallet.

    The recoverers then just click on the recovery link.

    Sign and Broadcastโ€‹

    In addition to social recovery, we will also migrate our Sign and Broadcast feature. It scans the QR code provided by polkadot.{js}, signs it, and broadcasts it to the network.

    Improvement on Parity Signerโ€‹

    Parity Signer scans QR codes that are produced by polkadot.{js}. Parity Signer is a fully airgapped wallet, so the payload is signed on the device and the signed QR code is scanned back into browser plugin to be broadcast.

    Our wallet will scan the same QR codes, but broadcast it to skip the step of having to scan the QR back in. Scanning QR codes from mobile back into a webcam is an extra step. It is the most time consuming part because you have to align the phone over the webcam correctly, and it always takes another second or two to focus on the QR code.

    With social recovery fully implemented, wallet users can be more confident leaving their mobile wallets online.

    Scopingโ€‹

    • Features - All steps of the Social recovery on Substrate article will be implemented.
    • Deployment - We will deploy the wallet to iOS and Android application stores.
    • Maintenance - We will maintain the components on the mainline releases of Substrate for no less than 2 years

    Development Status ๐Ÿ“–โ€‹

    We have started research of how to integrate Polkadot JS into the flutter app.

    https://github.com/JoinSEEDS/seeds_light_wallet/tree/feature/polkadot1

    We have deployed a full implementation in the Seeds Light Wallet

    We created a video showing off how the feature works on Telos - it's going to be a bit different due to the way Polkadot recovery pallet works, but 90% of the design and specifications are going to be the same (wait on recover, prevent hacks, set up guardians). It's less than 5 minutes, enjoy!

    Project Overview ๐Ÿ“„โ€‹

    This is the second grant for the Societal Labs team, after the sucessful submission and merge of our first W3F grant.

    Overviewโ€‹

    Societal is a specialized blockchain for the creation and management of Decentralize Autonomous Organizations (DAOs). Societal allows all types of groups or communities to build their own online, transparent, and decentralized organization. Societal bundles all of the tools required to create and manage a DAO in one place. Creators will be empowered to construct a DAO with fungible, non-fungible, or a combination of governance tokens. Societal also offers DAO management tooling features like treasury management, specialized governance, task boards, legal structuring, and accounting. This removes the need to utilize siloed platforms to manage the operations of a DAO. Whether a creator is looking to build a DAO for their organization, raise and deploy investment capital, or decentralize governance of an NFT project, Societal has the necessary tooling for a seamless end-to-end experience.

    Utilizing Polkdaotโ€™s layer-0 infrastructure and ecosystem, Societal will provide DAOs with both maximum functionality and a cohesive user experience. With features including agnostic token compatibility, zero gas fees, a freemium entry point, and a SaaS-based membership pricing, Societal combines best-in-class features into one vertically integrated product. With integrations into DeFi, privacy, and identity protocols, Societal will enable web3 organizations to seamlessly transition and manage their DAOs into the future.

    The Societal team has been building in the Polkadot ecosystem for the past two years. While at a previous Polkadot project, the Societal team noticed a lack of integrated DAO tooling - not only in the Polkadot ecosystem, but in the broader web3 industry as a whole. After analyzing how we might transition and manage our previous project into a DAO, there was no clear path. This, along with the team being both members and council members of various DAOs and noticing the lack of infrastructure, we decided to build a solution - Societal.

    Project Detailsโ€‹

    Societal Labs has been designing the product vision of the Socital platform for quite some time. We will go over the project details and blockchain architecture in this application and provide references below for more in-depth context.

    In Societal's final state, it will offer four main services; Create, Transition, Transfer and Manage. Create will allow any web3 user to create their own DAO. Transition will allow protocols to progressively move towards community ownership. Transfer will allow DAOs to transfer their DAO from an expensive siloed chain to the Sociteal platform. Manage will provide DAOs all the required product features to manage their organization, whether it is a small investment club or a large community-governed protocol.

    Societal will offer a wide range of features to create and manage a DAO. The features are split into three categories; Operations, Treasury, and Governance. The Operations features are: job & task boards, payroll, customizable feeds, legal tooling, on-chain reputation, and web & mobile application. The Treasury features are as follows: treasury wallets (multi-sig), DeFi integrations, on-chain cap table, accounting and private asset integrations. The governance features are: zero gas fee governance, proposal calendar, built-in governance models, governance treasury execution, and private voting.

    Societal will vertically integrate with projects to advance its tech stack and product offering, something not seen in most web3 projects today. For example, Societal can integrate DeFi services by working with projects like Acala, Parallel, and Composable Finance, which will allow for active treasury management for DAOs managed with Societal. For private assets and voting, projects like Manta and Phala can provide privacy-enabling functions like zero-knowledge proofs and trusted execution environments to make this possible. For on-chain credentials, projects like KILT and Litentry can provide KYC and member credentialing services that can be used by DAOs for governance and recruiting.

    Finally, Societal plans to progressively transition into a DAO itself. Once the token is launched, a community-run treasury will grow over time until the entire network is owned and operated by the community.

    Ecosystem Fitโ€‹

    As it stands today, the DAO landscape within the Polkadot ecosystem is not as mature as other ecosystems such as Ethereum. This is due to insufficient DAO creation and tooling infrastructure in the ecosystem. Currently, the Polkadot ecosystem does not have the creation, governance, treasury management, and payroll tooling products as other major blockchains. By building these tooling products on Polkadot, both the Polkadot DAO landscape and the broader DAO management tooling space are primed for innovation by utilizing the unique technical abilities that Substrate provides.

    The target audience of the Societal application are web3 users who require a platform to easily create and manage their DAO. Using the technical capabilities that Substrate provides, Societal will design our chain to be token agnostic, allowing current MetaMask users to easily connect to our chain and start using the governance application right away. By doing this, our project will meet the needs of the Polkadot community to create their own DAOs and have the tools to manage them as seen in other ecosystems.

    The projects like Societal in the Polkadot space are Polkassembly, SubDAO, and DoraFactory. Societal differs from these projects in multiple ways. First, Polkassembly is not building their own parachain and is only a governance platform for large Polkadot projects. Societal wants to allow any web3 user to create their own DAO - not just catering to large established protocols. SubDAO has recently been focusing on smart contract deployments on multiple chains and does not appear to be building a parachain. Societal will build its own parachain and use the technical capabilities of Substrate to be truly token agnostic, connecting with widely used wallets such as MetaMask, to avoid doing multiple chain deployments via smart contracts. Dora Factory is similar to Societal in the sense that they are building their own parachian, however we plan to offer zero gas fees and a SaaS based pricing model to enhance our user's experience. Societal will also seek to integrate with other parachains, having cross-chain smart contract execution.

    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Substrate Module: Reservable & Lockable Asset PalletThe main delivery of this milestone will be adding the 'ReservableAsset' and 'LockableAsset' Traits to the current Substrate Assets Pallet. By doing this, fungilbe tokens generate from the new Assets Pallet will have the same Reservable and Lockable features as the chain's native token from the balances pallet. These fungible tokens may then be used with the current Substrate Democarcy pallet, allowing DAOs create on Societal's chain to have similar feautres to Polkadot's Governance v1.
    2.Client ModulesA minor UI will be made to allow the user to interact with the new Asset Pallet and show that the functionality works. However, the major UI creation will be completed in milestone 2.

    1.Client ModulesWe will create a client facing UI that will interact with the Reservable & Lockable Asset Pallet. The main functionly of the UI will be to show how the fungilbe tokens generated from the new Assets Pallet can be used with the current Substrate Democracy Pallet. This will allow DAOs that have been created on the Societal network to have similar features to Polkdaot Governance v1 system, that only parachains can use right now.

    Future Plansโ€‹

    Societal plans to secure fundraising and expand the development team. After the completion of the milestones stated above, Societal plans to expand the product offering by implementing a DAO Dapp Market Place and a subscription pricing mechanisim. Societal has also applied to be a part of the Substrate Builders Program. Finally, Societal plans to launch its own parachain and be the go to DAO Creation and Mangament platofrm.

    Societal

    • Team Name: Societal Labs Ltd.
    • Payment Address: Ethereum - USDC: 0xcDcCF94f10d8A7165C1A336DD3795430a6CDE530
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    This is the third grant for the Societal Labs team, after the sucessful completion of two previous grants.

    Societal is also a member of the Substrate Builders Program.

    Overviewโ€‹

    Societal is a specialized blockchain for the creation and management of internative-native organizations. Societal allows all types of groups or communities to build their own online, transparent, and decentralized organization. Societal bundles all of the tools required to create and manage a DAO in one place. Creators will be empowered to construct a DAO with fungible, non-fungible, or a combination of governance tokens. Societal also offers DAO management tooling features like treasury management, specialized governance, task boards, legal structuring, and accounting. This removes the need to use siloed platforms to manage the operations of a DAO. Whether a creator is looking to build a DAO for their organization, raise and deploy investment capital, or decentralize governance of an NFT project, Societal has the necessary tooling for a seamless end-to-end experience.

    Utilizing Polkdaotโ€™s layer-0 infrastructure and ecosystem, Societal will provide DAOs with both maximum functionality and a cohesive user experience. With features including cross-chain governance and subscription pricing, Societal combines best-in-class features into one vertically integrated product. With integrations into DeFi, privacy, and identity protocols, Societal will enable web3 organizations to seamlessly transition and manage their DAOs into the future.

    The Societal team has been building in the Polkadot ecosystem for the past two years. While at a previous Polkadot project, the Societal team noticed a lack of integrated DAO tooling - not only in the Polkadot ecosystem, but in the broader web3 industry as a whole. After analyzing how we might transition and manage our previous project into a DAO, there was no clear path. This, along with the team being both members and council members of various DAOs and noticing the lack of infrastructure, we decided to build a solution - Societal.

    Project Detailsโ€‹

    Societal Labs has been designing the product vision of the Socital platform for quite some time. We will go over the project details and blockchain architecture in this application and provide references below for more in-depth context.

    In Societal's final state, it will offer four main services; Create, Transition, Transfer and Manage. Create will allow any web3 user to create their own DAO. Transition will allow protocols to progressively move towards community ownership. Transfer will allow DAOs to transfer their DAO from an expensive siloed chain to the Sociteal platform. Manage will provide DAOs all the required product features to manage their organization, whether it is a small investment club or a large community-governed protocol.

    Societal will offer a wide range of features to create and manage a DAO. The features are split into three categories; Operations, Treasury, and Governance. The Operations features are: job & task boards, payroll, customizable feeds, legal tooling, on-chain reputation, and a web & mobile application. The Treasury features are as follows: treasury wallets (multi-sig), DeFi integrations, on-chain cap table, and accounting. The governance features are: subscription based governance, proposal calendar, built-in governance systems, and private voting.

    Societal will vertically integrate with projects to advance its tech stack and product offering, something not seen in most web3 projects today. For example, Societal can integrate DeFi services by working with projects like Acala and Moonbeam, which will allow for active treasury management for DAOs managed with Societal. For private assets and voting, projects like Manta and Phala can provide privacy-enabling functions like zero-knowledge proofs and trusted execution environments to make this possible. For on-chain credentials, projects like KILT and Litentry can provide KYC and member credentialing services that can be used by DAOs for governance and recruiting.

    Finally, Societal plans to progressively transition into a DAO itself. Once the token is launched, a community-run treasury will grow over time until the entire network is owned and operated by the community.

    Ecosystem Fitโ€‹

    As it stands today, the DAO landscape within the Polkadot ecosystem is not as mature as other ecosystems such as Ethereum. This is due to insufficient DAO creation and tooling infrastructure in the ecosystem. Currently, the Polkadot ecosystem does not have the creation, governance, and treasury management tooling products that other major blockchains do. By building these tooling products on Polkadot, both the Polkadot DAO landscape and the broader DAO management tooling space are primed for innovation by utilizing the unique technical abilities that Substrate provides.

    The target audience of the Societal application are web3 users who require a platform to easily create and manage their DAOs. Our project will meet the needs of the Polkadot community to create and managane their own DAOs and will be a governace scaling solution for ETH based DAOs.

    The projects like Societal in the Polkadot space are Polkassembly, SubDAO, and InvArch. Societal differs from these projects in multiple ways. First, Polkassembly is not building their own parachain and is only a governance platform for large Polkadot projects. Societal wants to allow any web3 user to create their own DAO - not just catering to large established protocols. SubDAO has recently been focusing on smart contract deployments on multiple chains and does not appear to be building a parachain. Societal will build its own parachain and use the technical capabilities of Substrate to be truly token agnostic, connecting with widely used wallets such as MetaMask, to avoid doing multiple chain deployments via smart contracts. InvArch Factory is similar to Societal in the sense that they are building their own parachian, however we plan to offer a SaaS based pricing model so we can change the DAOs a monthly subscription fee and eliminate the fees for the organizations members. Societal will also seek to integrate with other chains, having cross-chain governace execution.

    Development Status ๐Ÿ“–โ€‹

    Societal has already been working on our project and has completed our MVP. The two main repositories of the Societal project are the societal-node and the societal-client. These repositories represent the societal blockchain (built with substrate) and the UI. To date or MVP includes the following features: Create a DAO with its own governance token, slecect a governance type (Gov1, ownership weighted voting, NFT voting), create and vote on proposals, and bounties. The Societal chain is also EVM compatible.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    • Total Estimated Duration: 4 months
    • Full-Time Equivalent (FTE): 2 FTE
    • Total Costs: 40,000 USDC

    The main purpose of this grant will be creating a subcription based pricing system, that can be implemented into any subsrate chain.

    Societal will use this subcription based pricing system to charge the DAOs on its network a monthly fee, which will allow the DAOs members to interact on-chain without paying gas fees. This will bring current web2 pricing models to web3, increasing user experience and ease of adoption for DAOs, as their members will not have to pay gas fees or hold the chain token to interact with it.

    Milestone 1 โ€” Subscription Pricing Palletโ€‹

    • Estimated Duration: 1.5 month
    • FTE: 2
    • Costs: 15,000 USD
    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.
    0c.Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Substrate module: Subscription Pricing PalletWe will create a Substrate pallet that will require organizations on substrate chain's network to pay a monthly subscription, which will allow the organizations members to interact on-chain without paying gas fees. The pallet will do four main things. It will accept a subscription payment from a DAO to the substrate chain's treasury. It will open or lock functions for the DAOs members based on if and when the payment has been made. It will have a time limit for these functions to be open, before another payment is required. Finally, it would specify a maximum amount of function calls that can be executed before the functions are locked and another payment is required, preventing DDos attacks.

    Milestone 2 โ€” Add Subscription Tiers to Palletโ€‹

    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Substrate Module: Add Subscription Tiers to PalletThe main delivery of this milestone will be adding differnt subscription tiers to the pallet that was created in milestone 1. This milestone will allow the developer to define different subscription tiers, the price of each tier, what functions and/or pallets are allowed in each tier, and the maximum amount of function calls for each tier. Based on what subcription tier the DAO is paying for, only those functions will be allowed to be called by the DAO and its members. Finally, this milestone will also allow each tier to have a maximum amount of members allowed in the DAO.

    Milestone 3 โ€” Add Recurring Subcription Payment to Palletโ€‹

    • Estimated duration: 1 month
    • FTE: 2
    • Costs: 10,000 USDC

    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish a tutorial that explains how to use and the functionality of the grant.
    1.Substrate Module: Add Recurring Subcription Payment to PalletThe main delivery of this milestone will be allowing the DAO to approve recurring subscription payments from the DAOs treasury. The approval for the automic recurring subcription approval will come in the form of a governance proposal. The subcription payment will allow for monthly recurring payments until the subscription in canceled. If funds are not avaible at the time of paymnet, all of the DAO functions except for paying the subscription will be locked. This milestone will make it easier for the DAOs to pay the subscription and not need to approve a proposal every month.

    Future Plansโ€‹

    Societal plans to launch its own parachain and be the go-to DAO Creation and Management platform for Polkadot and all of web3. We believe that this subscription pricing system will be a great on-ramp of DAOs from other ecosystems into Polkadot, as the organization members do not have to purchase the Societal token to participate in on-chain transactions. This will reduce the barrier for these DAOs to use a governance scaling solution for their organization, such as Societal. This subscription payment system can also be used by many substrate chains to reduce this barrier adoption as well.

    Current work - Scope of this Grantโ€‹

    Milestone 2 โ€” Upgrade focused on complex Smart contract applications parsingโ€‹

    NumberDeliverableSpecification
    0a.LicenseMIT
    0b.DocumentationWe will enhance both the inline documentation as well as the website with guides to reflect new features implemented in this milestone
    0c.Testing and Testing guideCore functions will be fully covered by comprehensive unit tests to ensure functionality and robustness. Documentation will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    1.Website with guidesWe will enhance the existing guides to reflect new features implemented in this milestone; The website with guides is something like an enhanced documentation, the inline documentation just describes the functions of the program, the guides go deeper into how it works, and it also contains a tutorial for usage of Sol2Ink
    2.Split contract into traitsCurrently all logic and storage is in one contract file. This upgrade will generate traits for each contract that the contract is using, splitting logic and storage into separate traits. This will also nicely handle inheritance of Solidity smart contracts
    3.Sol2Ink transpiler updateWe will update the transpiler to deal with code which it currently does not support or parses incorrectly
    3a.Functions with valueSupport calls with value transferring
    3b.Chained selectorsFix parsing of chained selectors
    3c.Updating structs inside of a mappingFix how Sol2Ink rewrites fields of a structure inside a mapping
    3d.ModifiersFix some occassions where parsing of a modifier causes the output code to be uncompilable (for example if there is a function call as a modifier argument
    3e.Fix bugsFix many small bugs which can occur, after this a more complex contracts (e.g. Uniswap) can be fully covered with Sol2Ink
    4.Library parsingWe will implement the parser for Solidity libraries; currently Sol2Ink only looks for definition of a contract or an interface, since libraries must be handled in a different way, meaning that there is no problem in parsing of Solidity code of a library, but the output code of a Solidity library must be handled in a different way, which is the goal of this deliverable
    5.Handling dependencies and generalizationThis will be implemented via traits
    6.Multi-file project parsingThis will be implemented via traits

    Overviewโ€‹

    This project aims to deliver an implementation of the parity trie verifier as required by state proof checking algorithms (read_child_proof_check, read_proof_check_on_proving_backend) in the Solidity programming language, which would include various sub implementations (for example NodeCodec for both layoutv0 & layoutv1) required to build trustless bridging protocols from the Polkadot ecosystem to the EVM ecosystem.

    Goal: To create a primitive for more generalized bridging protocols like IBC, it is more efficient to verify Parachain state/storage than to use custom implementations which Darwinia and Snowfork do.

    Solidity Verifier Implementation for Accountable Light Client

    • Team Name: Itering
    • Payment Address: 0x5FD8bCC6180eCd977813465bDd0A76A5a9F88B47 (Ethereum USDC)

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    As a developer company contributing to Darwinia, Itering is working on implementing an on-chain accountable light client verifier using the Solidity language. The accountable light client design is based on a recent paper published by the Web3 Foundation.

    Darwinia is constantly following innovations in the cross-chain space, especially from the Web3 Foundation and Polkadot, with a goal of implementing these innovations in practical settings. Currently, Darwinia is prioritizing the development of on-chain light clients as the cross-chain solution. We recognize the importance of the accountable light client system presented in the paper.

    Project Detailsโ€‹

    After reading the paper, we found it to be extremely valuable. It presents an efficient method for utilizing SNARK to verify the aggregated public key of signers, while still holding those signers accountable. This approach greatly improves the speed and cost-effectiveness of proof generation.

    Darwinia has created a beacon light client from ethereum to darwinia, which is based on the BLS aggregate signature verification. The cross-chain gas is effectively reduced by aggregate signatures, but it is still too high because the light client smart contract needs to be aware of the entire list of public keys. If there are too many pubkeys, this could be a serious issue.

    So, we are searching for a more effective solution to the aggregate signature pubkeys problem. We concentrate on the honest computation provided by zero-knowledge proof solutions. It allows us to off-chain the verification step. But through our study, we discovered that the generic SNARK solutions have so many limits that not only took a long time to produce the proof, but also required an extremely powerful device. We were stuck here until we came across this paper and Alistair's explanation video and slides.

    This verifier will be implemented based on the BLS12-377 and BW6-761 elliptic curves, which is consistent with the implementation in the paper and W3F's PoC implementation.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

      When Polkadot/Substrate/Kusama bridges to a blockchain that is EVM-compatible, this verifier will be helpful.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

      The users of this verifier will be the cross-chain messaging/bridge service providers.

    • What need(s) does your project meet?

      Precompiled versions of BLS12-377 and BW6-761 should ideally be supported by the blockchains that use this verifier.

      If gas and speed are not a concern, you can also use the no-precompiled curves.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

      This kind of verifier hasn't been implemented in solidity yet, as far as we know.

    Spacewalk: a Stellar bridge

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Spacewalk is a bridge between Substrate-based parachains and Stellar which enables asset transfers to and from Stellar. This grant application is for developing the Spacewalk protocol and pallet. The Spacewalk bridge is built by the team behind the Pendulum network (an upcoming parachain that connects fiat tokens from across multiple blockchain ecosystems).

    Project Detailsโ€‹

    Spacewalk bridge is developed to be a decentralized and trustless bridge to Stellar. This bridge enables two main activities:

    • Deposit: bridge any Stellar asset to Substrate-based chains. The tokens of the source asset are transferred to some dedicated vault in Stellar where they are locked. The bridge then mints wrapped tokens in the target chain and transfers them to the recipient account.
    • Withdrawal: bridge wrapped tokens in Substrate-based chains to Stellar. First, the user instructs the bridge to burn wrapped tokens in the Substrate-based chain. Afterwards, an appropriate vault unlocks tokens and transfers them to some target account.

    Stellar is not smart contract capable โ€“ therefore we follow the recommendation laid out in the Polkadot documentation and base our bridge design on XCLAIM, which is based on the following four core features:

    • Implement a chain relay for Stellar in the bridge pallet
    • Employ collateralization in order to ensure that the vault exhibits good behavior
    • Ensure that the economic value of the collateral exceeds the value of the vault
    • Enable a decentralized network of vaults

    XCLAIM has been implemented and further improved by Interlay for the open source Bitcoin bridge interBTC. Spacewalk is based on the interBTC implementation. It differs from interBTC as follows:

    • Currently Stellar does not use Merkle trees inside its blocks. Therefore, there is no efficient way to prove that a transaction is included in a block given only the block header โ€“ a prover would require to complete the complete set of transactions instead of a Merkle path.
    • Stellar does not employ Nakamoto consensus but a custom consensus algorithm called Stellar Consensus Protocol. For that reason it is not possible to infer from sequences of block headers alone which sequence is valid โ€“ย for Nakamoto consensus this is simply the sequence with the highest amount of work.
    • Stellar supports custom assets: every account holder can create new assets and mint their own tokens. Spacewalk supports to bridge any Stellar asset to the Substrate chain. This implies that the Spacewalk pallet can dynamically create and mint new assets that are not known beforehand.

    The first two differences imply that there is no efficient way to implement an SPV client and a chain relay for Stellar. Spacewalk will address this by replacing the chain relay with an oracle for Stellar.

    Architecture

    Stellar Bridge Web3 Grant(5)

    The architecture of the bridge consists of the following components:

    • Vaults: this is a set of escrow accounts used to lock assets in Stellar. Their behavior is defined in XCLAIM and interBTC. In Spacewalk they have an additional property: each vault has an allow list of assets that it can lock and support for bridging operations between Stellar and the Substrate chain. This allow list is implemented through trustlines of the Stellar account. There can be at most 1000 supported assets per vault due to limitations in Stellar. Stellar users initiate a deposit by sending tokens to an appropriate vault, which they request from the bridge pallet prior to the deposit. Likewise vaults will unlock and send tokens back to Stellar accounts during a withdrawal. Every vault needs to lock a certain amount of DOT or KSM (or related) tokens as collateral with the bridge pallet. These tokens are slashed in case the vault misbehaves.
    • Bridge Pallet: this is the main component of the Spacewalk bridge that implements all logic on the side of the Substrate-based chain. Its behavior is based on interBTC. It is particularly responsible for minting tokens during deposits and burning tokens during withdrawals. It is able to support any Stellar asset by employing the Tokens and Currrencies pallets of the Substrate Open Runtime Module Library. The storage of the bridge pallet maintains the complete state that is required for the bridge to work correctly. This state contains (among others): the account ids of the vaults, the asset allow lists of each vault and book keeping information about the state of the Stellar network.
    • Stellar Oracle: is a decentralized system that provides information about the state of the Stellar network to the bridge pallet. In interBTC this is implemented through a Bitcoin chain relay. However, for reasons explaned above we cannot implement a chain relay for Stellar in the same way. The Stellar oracle is trustless and reliable and its functionality is based on specific unique aspects of Stellar:
      • The Stellar network has multiple levels of tiers, where the nodes in Tier 1 enjoy the highest level of trust of its peers. There are currently 23 Tier 1 nodes; this set and its structure is rather static and only changes rarely. It only ever changes through a voting process. We will incorporate complete information about the Tier 1 network in the bridge pallet.
      • Every Stellar node has a static signing key pair and signs messages that it gossips to the network. Particularly, every node announces through a signed message that a block has been finalized. The decentralized oracle will forward these signed messages from Tier 1 nodes to the bridge pallet. This way the bridge pallet can reliably infer what Stellar blocks are finalized.

    Out of scope

    The following aspects are out of scope of the current proposal and subject to future applications:

    • Stellar protocol updates that are required to implement a chain relay/light client/simplified payment verification for Stellar as a Substrate pallet

    Ecosystem Fitโ€‹

    The Spacewalk bridge is the first bridge between the Stellar network and the Polkadot/Kusama ecosystem, which opens up a flow of stable tokens from the Stellar network into the Polkadot/Kusama ecosystem and, simultaneously, allow any Substrate-based blockchains to implement a direct Stellar bridge.

    As part of the Pendulum goal of bringing as much fiat-based token liquidity to the parachain ecosystems, Spacewalk plays a central role. Furthermore, the entire community can benefit from this bridge by innovating on the open source code.

    Currently, we are not aware of any projects in the Substrate/Polkadot/Kusama ecosystem that are building a bridge to the Stellar network, but similar bridges are being built for Ethereum layer 2 networks, such as the Newscrypto bridge between Polygon and Stellar.

    The Spacewalk project grows beyond the first version alongside the community of users and open source contributors, as we have seen interest in both the Stellar and Substrate communities for such a bridge. Pendulum itself will be the first use case for the bridge and will naturally justify further investment in maintenance and expansion.

    Overviewโ€‹

    Tagline: Proof-of-Capacity Consensus for Substrateโ€‹

    The key objective of this grant is to design and build a production ready substrate chain which employs Spartan, a simple proof-of-space consensus algorithm. Our long-term goal is to implement Subspace, a new Proof-of-Capacity (PoC) consensus blockchain, in Substrate through a follow-up general grant. After careful analysis, we have determined that implementing the full plan for Subspace goes well-beyond the scope of an open grant. However, as any proof-of-replication is based on a proof-of-space, we can begin with the simpler task of implementing the more abstract notion of proof-of-capacity consensus. Based on our experience working with Substrate so far, implementing a novel consensus mechanism is non-trivial and requires a deep understanding of the internals of FRAME and Substrate. We would therefore like to take the time to do this right.

    Relevance to Substrate & Polkadotโ€‹

    With respect to Substrate, existing consensus mechanisms include proof-of-authority (Aura), proof-of-stake (Babe), and proof-of-work (Kulupu). We would like to extend this with two more constructions: proof-of-space (Spartan) and (in a later grant) proof-of-storage (Subspace). Both of these are instances of a more general class of of proof-of-capacity protocols, which seek to replace "one-CPU-one-vote" with "one-disk-one-vote". Upon completion, this grant would serve to further demonstrate the flexibility of Substrate and FRAME for any abstract blockchain. Other teams seeking to implement slot-based PoC blockchains would also be able to re-use the core crates to reduce development time. Note that any proof-of-replication implies an underlying proof-of-space. We therefore intend to begin with the much simpler task of implementing Subspace as a pure proof-of-space consensus protocol (Spartan) before extending it into a full proof-of-storage (or replication) protocol envisioned in our whitepaper.

    Team Motivationโ€‹

    Ultimately we want to make it as easy possible for developers to build applications where users can have full control over their data. We believe blockchain-based decentralized applications reflect the best hope for this future, but have been disappointed with the sustainability, scalability, and fairness of existing options. We are building Subspace in an effort to remedy this gap, while making decentralized storage central to the design. With respect to this grant, our goal is to master the internals of Substrate so that we may leverage its rich ecosystem to create a solid foundation for our own chain, while providing an extensible set of interfaces that may be used to build any abstract proof-of-capacity blockchain.

    Project Detailsโ€‹

    Key Deliverablesโ€‹

    1. A set of abstract crates for Proof-of-Capacity (PoC) consensus: sp_consensus_PoC and sc_consensus_PoC.
    2. A proof-of-space consensus pallet, pallet_spartan, which implements these primitives using sp_consensus_spartan and sc_consensus_spartan.
    3. An implementation of substrate-node-template which employs pallet_spartan to construct a PoC blockchain client.
    4. A decoupled farmer, responsible for plotting and evaluating challenges, which connects to the client via the existing RPC.
    5. A demonstration of a live test network, consisting of multiple nodes (farmer/client pairs), with variable sized plots and adaptive difficulty.
    6. Extensions to polkadot-js which display the new relevant consensus information within the block explorer.

    These crates and pallets will begin as forks of sp_consensus_babe, sc_consensus_babe, and pallet_babe. Spartan and Babe share the same notion of timeslots and epochs as expressed in Ouroboros Praos. The key differences are that Spartan has no notion of authorities (it is permissionless) while we may largely replace the VRF evaluation & verification with evaluation of the farmerโ€™s plot and verification of the proof-of-space. Spartan and Subspace also have much in common, as they both use the same underlying SLOTH permutation, they have almost identical farmer implementations, and the consensus mechanisms are the same. The key difference is that Spartan is based on permuting a deterministic genesis piece with a nonce, while Subspace is based on permuting the actual blockchain history. This means that we can later extend Spartan consensus into Subspace consensus with minimal rework.

    User Interfaceโ€‹

    The UI will consist of a simple CLI for the farmer and client with relevant extensions to the Polkadot-js GUI.

    Imgur

    Spartan-Farmerโ€‹

    This has a deliberately simple CLI with two commands: plot and farm. The plot command allows the user to specify the plot size (in bytes), an optional storage path, and an optional seed for the private key. Plotting time depends on the hardware used but will take roughly 36 hours for a 1 TB plot using a standard quad-core machine. The plotter displays a progress bar showing percent complete and outputs some plotting statistics on completion. Once a plot has been created, the farm command may be used to connect to a client with an optional Web Socket address. The farmer will display relevant log messages during operation.

    Spartan-Clientโ€‹

    No new commands will be added to the client CLI, though we will add additional logging messages to reflect interaction with the farmer.

    Spartan-Browserโ€‹

    No new commands will be added to the browser-based polkadot-js GUI, though we will modify the display of relevant consensus information.

    Technology Stackโ€‹

    The farmer will be written in Rust. The CLI will be constructed using clap. Connection to the Substrate client will be mediated using jsonrpsee. The plot file itself will be written directly to disk using async-std. The binary search tree, used for evaluating the plot, will be built using RocksDB. All cryptographic primitives (signatures, hash functions, HMACs) will come from Substrate libraries. The SLOTH permutation is based on our own implementation of SLOTH using rug. The client will be based on the standard substrate-node-template. All consensus pallets will be based on pallet_babe and relevant slot based consensus crates. The browser GUI will extended from polkadot-js with all modification written in Typescript.

    Proof-of-Concept (prior work)โ€‹

    An initial implementation of Subspace was previously written in Rust, from scratch, without forking another chain. While we were able to get a rudimentary transactional blockchain working, which used proof-of-storage consensus, it quickly became clear that going from proof-of-concept to production ready (with all relevant tooling) was far beyond the capabilities of our team. We then learned about Substrate and began exploring the feasibility of porting over our work. This resulted in a smoke test of sorts, which showed that we could hack pallet_babe into pallet_spartan, connect to a spartan-farmer, and hook into the block production pipeline. The purpose of this grant is to take the lessons learned from writing our own implementation using this quick and dirty hack of babe, to create a production ready set of components which leverage the Rust trait system and the idiomatic FRAME methodology of decoupled crates and pallets, in order to build the foundation for a proof-of-capacity blockchain, which can leverage the full power of Substrate and provide a novel distributed storage solution for the Polkadot ecosystem.

    Non-Goalsโ€‹

    We must be very clear that we are not intending to implement the proof-of-storage consensus, distributed storage layer, or decoupled execution protocol as described in our technical whitepaper. Instead, this is only a stepping stone towards those goals. This will only implement a simple transactional blockchain powered by proof-of-space consensus. While we do intend for this implementation to be secure against all known attacks, we do not plan to launch Spartan as an actual production parachain or independent blockchain. Instead, this will only result in an initial test network for evaluation purposes.

    Ecosystem Fitโ€‹

    Background on Subspaceโ€‹

    Subspace is a blockchain secured by free disk space. This space is used to store provably-unique replicas of the history of the blockchain itself. This is in contrast to blockchains like Burst, Mass, Chia, and Spacemesh, which employ consensus based on a useless proof-of-space of random data. Similar to Filecoin, we employ a useful proof-of-storage, or a proof-of-replication, but instead of storing off-chain user generated date, the data is the history of the blockchain itself, i.e., the block headers and transaction data, yielding a proof-of-history or a proof-of-archival-storage.

    User generated data may still be retained by embedding it within a transaction, providing a permanent and immutable form of distributed storage, in contrast to the temporary and mutable distributed storage provided by Filecoin. This is most similar to the archival storage provided by Arweave. However, we base consensus entirely on disk space while ensuring many unique replicas of the blockchain are stored, whereas Arweave bases consensus on proof-of-work while only ensuring a single copy of the blockchain is retained (in the case of a single large mining pool). Since we can also estimate the amount of space pledged to the network by the average quality of the proofs-of-storage, and we know the size of the blockchain itself, we can then dynamically adjust the transaction fees to reflect the cost of storage. Unlike other networks, this allows for an efficient market for permanent distributed storage based on supply and demand.

    Subspace has also been specifically designed to maintain the security, decentralization, and permissionless nature of Nakamoto consensus, as exemplified by blockchains such as Bitcoin and Ethereum. It retains safety and liveness, given that a majority of the space pledged to network is controlled by rational farmers. It also designed to overcome a series of subtle mechanism design challenges unique to proof-of-space/storage blockchains which we refer to as the farmer's dilemma. This allows Subspace to apply a variety of layer one scaling proposals to achieve high transaction throughput and low confirmation latency, without sacrificing the security or decentralization of the network.

    Relevance to Polkadotโ€‹

    Subspace provides a scalable distributed storage layer for Polkadot, by allowing parachains to have a native, low-cost, and permanent storage option. Within the polkadot ecosystem, we are targeting other parachains and dApp developers on smart contract capable parachains. We are also exploring similar use-cases outside of the Polkadot ecosystem. Subspace can ensure the longevity and availability of data which is too expensive (i.e. by tx costs) to store on the source chain, or would negatively impact the decentralization of the chain (i.e., by increasing blockchain bloat).

    We intend to eventually launch Subspace as a parachain on Polkadot. This will allow any other parachains within the Polkadot network to utilize Subspace for permanent distributed storage. In the extreme form, each parachain block could be backed-up on the Subspace network, allowing for higher levels of decentralization and permanent data availability (even if the parachain later ceases to exist). In the average case, a parachain could employ Subspace to retain data which is too large to store internally, either through the native runtime logic or by individual smart contracts. While the same functionality is theoretically possible with networks like Filecoin and Arweave, if Subspace is also a parachain, the cost of cross-chain communication would be much lower.

    Inside the Polkadot ecosystem, Crust Network is the only existing option for off-chain distributed storage. Crust resembles Filecoin in many ways, except that it uses a Trusted Execution Environment (TEE) in places of proofs-of-replication. This limits the storage capacity of the network to providers who have special purpose hardware, making it far less decentralized and more expensive. In contrast, Subspace allows anyone with free disk space and minimal computation to act as a storage provider, allowing it to scale to many orders of magnitude larger network storage capacity. Crust, like Filecoin, also provides temporary and mutable storage, whereas Subspace provides permanent and immutable storage, which is often more suitable for blockchain-based applications and smart contracts.

    Outside of the Polkadot ecosystem there are several storage-based networks. At a high level Subspace provides both an alternative consensus mechanism (proofs-of-archival-storage) and a distributed storage network for arbitrary data. In the first case it builds on the work of blockchains such as Burst, Mass, Chia, and Spacemesh, while resolving the incentive challenges related to the farmerโ€™s dilemma (described in our whitepaper), and is therefore much more suitable for scalability. In the second case, it provides a generic platform for distributed storage, similar to Sia, Storj, Filecoin, and Arweave. Our construction is closest to Arweave, but far more incentive-compatible since consensus is based entirely on proofs-of-storage, whereas Arweave is mainly secured by proof-of-work.

    Milestone 1 โ€” Implement Local Development Chainโ€‹

    • Estimated Duration: 4 weeks
    • FTE: 2
    • Costs: 10,000 DAI

    This milestone will allow for the operation of a local development chain, with a single substrate client connected to a single farmer. The farmer will be entirely decoupled, and connect over the existing RPC, though it will still be written in Rust and re-use shared primitives. The client will employ a set of consensus crates, based on modifications to pallet_babe and its dependencies. The blockchain will not have a finality gadget and will only support basic payment transactions.

    • FTE: 2
    • Costs: 10,000 DAI

    This milestone will extend the local development chain into a test network. Full and light clients will be able to synchronize the chain state. Multiple nodes (client/farmer pairs) will be able to co-farm simultaneously, with an a adaptive work difficulty that adjusts based on the amount of disk space pledged to the network.

    • Costs: 9,999 DAI

    This milestone will extend naive consensus to be secure against all known attacks, as described in the technical whitepaper.

    Stable Asset

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    There are vastly emerging assets in the Polkadot ecosystem, including both Polkadot native assets and assets bridged from other blockchains such as Ethereum and EOS. These assets introduce diversity in architecture and business model, but also fragmentizes the ecosystem since applications need to build separate markets for each of these assets. For example, stables coins can be divided into three categories: fiat-backed, crypto-backed and algorithmic stable coins, and on Ethereum each category has more than ten stable coin protocols. DEX benefits from such asset diversification but other protocols such as lending and options find it difficult to accommodate all these various assets.

    Asset synthesis is a common approach to unify asset values and hedge asset risks. One approach is to synthesize several mainstream assets or assets belonging to the same niche so that the synthetic assets represents the general trend of the underlying assets. In this approach the synthetic assets acts similiar to an index fund, and how to fairly price and adopt the synthetic assets becomes a new question. The second approach is to synthetize several assets of the same value peg such as BTC, ETH or USD. The synthetic asset has the same value peg, and it could simplifies financial application development since only one synthetic asset needs to be supported for each peg type.

    Stable Asset is an asset synthetic protocol of the second approach. It is also built with integrated swap and saving functionalities using the basket of assets.

    Project Detailsโ€‹

    The Stable Asset is an asset synthetic protocol based on Curve's StableSwap algorithm as shown below:

    Stable Swap Algorithm

    Widely adopted as swap algorithm among assets with the same peg, it also works perfectly as an asset synthesis algorithm with a basket of assets with the same peg due to the following properties:

    • When the prices of all underlying assets in the basket are equal, the number of each underlying assets in the baskets are equal as well. At this moment, the value of the synthetic asset equals the total number of underlying assets in the basket, and the collateral ratio reaches 100%;
    • Whenever the price of any underlying asset differs from each other, the value of StableAsset is smaller than the total number of underlying assets so that the collateral ratio is larger than 100%. Since all assets in the baskets are of the same value peg, their prices should fluctuate about the peg prices with low variation expected so that the overall collateral ratio should be slightly over 100%;
    • Users of the underlying swap can help to maintain the basket balance subject to underlying assets price shift.

    The Stable Asset system consists of three major components: Stable Asset, Stable Swap and Stable Savings.

    Stable Assetโ€‹

    Stable Asset is a synthetic asset with value peg such as BTC or USD. It's backed by a basket of assets with similar peg, and it provides more reliability and better peg compared to individual asset in the basket.

    The value of Stable Asset is derived from Curve's StableSwap algorithm. When there is shift in price from individual asset in the basket, the value of Stable Asset remains unchanged: The total value of Stable Asset is always the total amount of assets in the basket when their prices are all equal.

    Stable Swapโ€‹

    Stable Swap is a DEX built on top of the basket which is backing Swap Asset. It serves several purposes in the systems.

    • First, it enhances the capital efficiency of the baskets. Instead of staying still, the asset basket is used as DEX;
    • Second, it helps maintain peg of Stable Asset. Since the prices of individual asset might shift over time, DEX users can adjust the basket composition in order to reflect the current underlying asset value;
    • Third, the trading fee, along with the Stable Asset redemption fee, provide native yield to the Stable Asset holders.

    Stable Swap component is built with Curve's StableSwap algorithm with enhancement to better support the value of Stable Asset. It's different from the Curve DEX in that:

    • Its value composition is calculated based on the instrinic value of the Stable Assets instead of value of the underlying assets;
    • It has more robust and flexible basket management functionalities which are not required in DEX;
    • It's optimized in asset value computation.

    Ecosystem Fitโ€‹

    Equilibrium is planning to deliver a Curve AMM which is also based on StableSwap algorithm. Stable Asset, on the other hand, is a synthetic asset protocol built on top of the StableSwap algorithm with the following enhancement worth highlighted:

    • Liquidity providers received a strongly peg asset instead of LP token so that they don't lose usability of their assets;
    • Users of the DEX helps the synthetic assets to maintain peg in cases of asset price shift;
    • Holders of Stable Asset have native interest coming from the system itself.

    In short, Equilibrium is a DEX while uses the bonding curve to compute the balance of the underlying assets, while StableAsset is a synthetic asset which uses the bonding curve to maintain the derived value of the basket.

    Similar to Equilibrium, Sunrise DEX is a DEX that focuses on swap functionalities. On the other hand, StableAsset focus on asset synthesis and the Stable Swap module is an internal system that helps keep the basket balanced.

    Laminar is an over-collateralized synthetic asset protocol that uses various underlying assets to generate a value pegged assets. StableAsset is highly optimized for asset synthesis with a basket of assets with the same peg, and it can achieve a collateral ratio closed to 100%.

    Project Overview ๐Ÿ“„โ€‹

    This proposal is in response to an RFP for an Uncollateralized Stablecoin (Specifically: https://github.com/w3f/Grants-Program/blob/master/rfps/uncollateralized-stablecoin.md).

    Overviewโ€‹

    • A brief description of your project.

    We are proposing a functionally different approach for an uncollateralized stablecoin. Extant uncollateralized stablecoin solutions are based on creating and burning an ERC20-style token. By monitoring exchange rates and managing the token supply, these uncollateralized stablecoins seek to balance supply and demand to peg the exchange rate to a reference currency. To date, none have achieved commercial success and the inherent limitations and flaws of this architecture are quickly becoming apparent even with a theoretically perfect implementation. This paper dives deeper into the current challenges (https://papers.ssrn.com/sol3/papers.cfm?abstract_id=3952045), the first of which is a baseline support level of demand for operational stability which this RFP seeks to address.

    Stardust Labs is proposing a fundamentally different approach that uses financial derivatives to programmatically and algorithmically generate a "synthetic" derivatives-based stablecoin that can be originated or settled on demand.

    At a high level, the primary focus of stablecoins is risk mitigation. Modern commercially successful architectures derisk by having a centralized entity issue tokens based on physical reserves of the pegged currency held in custody. The primary problem here is trusting the custody of a centralized entity, a particular challenge considering most are cross-border, transnational companies with limited auditing and opaque balance sheets.

    Our proposal is to utilize the latest advancements in decentralized finance to instead originate synthetic financial derivatives on demand. This securitized financial instrument would emulate the stability and utility of a stablecoin without requiring collateral or physical custody. In short, put-call parity allows the algorithmic construction of a synthetic financial instrument from perpetual contracts that effectively locks the value relative to the pegged currency at the risk free rate. By securitizing this construct into a token we can generate a synthetic stablecoin on demand as well as close them on demand as long as a perpetual contract can be accessed and decentralized markets maintain enough liquidity in the perpetual contract market.

    • An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama.

    What we are proposing is relatively unprecedented but there are promising signs. Angle Labs launched on Ethereum last year as an ERC20 token in order to provide a stablecoin pegged to the Euro. They term themselves "the first decentralized, capital efficient and over-collateralized stablecoin protocol" (https://www.angle.money/). Angle Lab's stablecoin is collateralized with Ethereum and more specifically over-collateralized to ensure safety. In July of 2021 they published a whitepaper indicating that they were going to deploy self-minted perpetual contracts as a tool to bring in additional collateral and protection against large price moves. These perpetuals provide additional outsourcing of risk in addition to directly increasing ETH collateral. 5 months ago, they raised $5M from a16z and others to explore the technology. Our proposed architecture would bring that attention and innovation to the Polkadot network. More importantly for the Polkadot ecosystem, our proposal is decentralized and truly uncollateralized as it manages risks entirely through derivatives, and can generate synthetic stablecoins between any arbitrary pairs provided there is a perpetual contract market with sufficient liquidity.

    • An indication of why your team is interested in creating this project.

    Stardust Labs is focused on developing foundational advancements in distributed ledgers that improve consumer and user safety. Our overall goal is to build safer, more efficient financial infrastructure for the public. While extant distributed ledger applications have largely solved the use case of peer to peer payments, extant implementations of stablecoins currently have challenges that limit their use or safety.

    Stardust Labs is specifically drawn to this RFP as our team has extensive expertise in developing safe and efficient financial products for traditional commercial banks and specific subject matter expertise in decentralized finance and financial engineering. We ultimately believe an uncollateralized, independent stablecoin would have unprecedented utility in the space.

    Project Detailsโ€‹

    Historically stablecoins have been roughly one of two types. The first are asset-backed tokens controlled by centralized entities that maintain custody of physical assets. These assets could be fiat currencies, a basket of cryptocurrencies, or physical commodities. Examples of this are Tether (USDT), Gemini Dollar (GUSD), and Paxos Gold (PAXG). The second are algorithmically maintained ERC20 tokens that are actively minted or burned based on dex trading exchange rates to maintain parity.

    The challenge with the former is that a user is implicitly trusting the centralized entity to maintain those assets with no guarantees. With the latter, it is easy to mint coins during periods of increasing demand, but it is very difficult to burn tokens during periods of decreasing demand.

    Stardust labs recommends a fundamentally different approach. The primary utility of any stablecoin is mitigating the risk of future price movements. The past year has seen strong developments in decentralized financial markets and powerful tools for de-risking in the form of options and perpetual contracts. We can use these products and financial engineering to create a synthetic financial instrument that replicates the performance of a stablecoin on demand. As long as the underlying asset can reach a sufficiently liquid options pair, we can combine products to create a stable structure that ultimately results in a fixed future return in the pegged currency at the risk free rate thanks to put-call parity. If this relationship is broken, that mathematically means that a profitable risk-free arbitrage opportunity exists which should be very short-lived in efficient, open financial markets.

    Defirate has a good in-depth explanation of both how perpetual contracts work and how they can be hedged to earn the nominal interest at the risk-free funding rate. (https://defirate.com/perpetual-contracts/)

    Ultimately, our proposed stablecoin isn't a managed token or backed by an underlying asset. Instead, the stablecoin smart contract purchases and returns a tokenized, engineered bundle of options and perpetual contracts that, combined, ensure a stable price relative to the pegged currency in the future. We term this type of asset a 'synthetic' stablecoin, termed because it is the exact same process as building a synthetic option. In addition, this process is similar to securitization whereby several financial products are pooled to yield a purchasable interest-bearing security with a different risk-reward curve.

    The astute reader will observe that constructing these synthetic options will incur a cost. However, the advent of flash loans and depository institutions like AAVE allow the capital in the smart contracts to be deployed to generate risk-free interest, allowing the stablecoin contract to offset the cost of purchasing these options. We envision the smart contract assessing either a transaction fee for origination or a penalty for early withdrawals where users have not held the synthetic stablecoin long enough for the interest to offset the contract purchase fees and transaction costs. Though it varies dramatically, Bitcoin futures seem to have a 3.69% risk-free rate (https://quantpedia.com/what-is-the-bitcoins-risk-free-interest-rate/), the risk free rates at Binance for Perpetual contracts (the funding rate) is 0.01% every 8 hours (or an annualized rate of 11.57%). Meanwhile, the fee to enter a perpetual ranges from 0.05%(dxdy) - 0.02% (Binance) so it is likely that these fees would be entirely covered by the interest payments on the overall stabilized value.

    Why Now & Risksโ€‹

    Ultimately this is only possible today thanks to both the recent advancements in decentralized finance, and more importantly the liquidity in the market. One of the outstanding risks to this stable coin is if liquidity quickly dries up. An example of the impact of liquidity shocks on securitized financial derivatives is best seen by the 2008 financial crisis. Unlike traditional financial markets however, positions are monitored in real-time and can be forcefully liquidated, preventing direct losses. However, there are fundamental limits on how much stability this construct or any uncollateralized stablecoin could absorb. One of the key outstanding questions, and the main exogenous risk that is currently unknown, is the strength of correlation between overall crypto prices, volatility, and its impact on the liquidity of decentralized financial markets.

    One of the primary anticipated challenges is the lack of regulatory oversight in the markets and the ability of individual companies to offer arbitrary leverage ratios. For example, Binance is offering 125x leverage meaning some perpetual contracts are at risk of being forcibly liquidated even with less than a 1% price movement. (https://bitcoinist.com/binance-125x-leverage-sparks-criticism-from-community/) Our smart contract can simply repurchase another perpetual contract during liquidation, however a risk exists that market liquidity would dry up during periods of unprecedented volatility such as a major market crash. Without liquid markets with leveraged counter-parties willing to absorb the risk, the synthetic stablecoin would be forced to return the money to the user in the underlying currency at the price of the stable peg, having done its job, but at the same time being unable to offer continued stability.

    Due to the use of options, perpetuals, and lack of human intervention, our proposed system is able to absorb far more volatility than algorithmically managed uncollateralized stablecoins. These implementations have strong negative feedback loops during periods of decreasing demand and, as of date, no robust solution for reducing supply. These struggles have caused many to fail even under benign conditions and these challenges will be dramatically amplified in the type of major market crash where liquidity in financial markets begins to dry up. At that point, the only efficient solution would be custodied collateralized assets by trustworthy centralized entities.

    Ecosystem Fitโ€‹

    A decentralized uncollateralized synthetic stablecoin has significant utility for decentralized financial applications and would be a transformative development beyond just the Polkadot ecosystem. In addition to providing a stable store of value that works synergistically with demand in the market, the smart contract mathematics are entirely fungible and can be set up for any arbitrary currency as the underlying asset and pegged currency provided a sufficiently liquid options market exists.

    The primary target demographic and audience would be decentralized financial applications and any user who seeks a stable store of value that isn't dependent on a centralized third party, instead risk has been decentrally allocated to the participants on decentralized markets.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Brief Descriptionโ€‹

    Zero-knowledge proof (zkp) is a cryptographic technology which enables you to prove that you know a secret without revealing it. It is a powerful tool in the paradigm of Web 3.0 where people can prove certain attributes about themselves without giving away their private data. It can also be used to prove computational integrity which can result in novel applications such as a private smart contract on a blockchain.

    However, it requires tremendous expertise to construct a zkp for certain computation. This hinders the adoption of this powerful technique for everyday use. Wouldn't it be great if we can construct a zkp for any general purpose computation without a deep understanding of zkp? Enter the Distaff VM, a zk-STARK virtual machine written in Rust. For any program executed on Distaff VM, a STARK-based proof of execution is generated. This proof can then be used by anyone to verify that a program was executed correctly without knowing the inputs to the program or even the program itself.

    The Starks Network is a zk-STARK based zkp parachain for the Polkadot/Kusama ecosystem. At its core, it uses the Distaff VM for zk-STARK proof generation and verification. Powered by the Substrate blockchain framework, the Starks Network can serve other blockchains and enable applications such as private smart contract and private credential verification.

    Substrate/Polkadot Integrationโ€‹

    Substrate is a powerful blockchain framework. It enables us to bootstrap the skeleton of the Starks Network in a short time. The Starks Network blockchain serves several purposes:

    • It keeps a record of all the proof verifications;
    • It provides a way to setup a smart contract for a computation and to carry out subsequent actions based on the proof verification result;
    • It enables the flow of economic incentives among the users and the verifiers.

    As already mentioned, other blockchains in the Polkadot/Kusama network can interact with the Starks Network via cross-chain message passing. Developers on other chains can design smart contract which benefit from zkp and they don't have to be experts of zkp at all.

    Team Interestโ€‹

    The Glacier Blockchain team is an advocate of the Web3 ideology. It strives to help build an open, transparent and inclusive network which returns the sovereignty of data to their owners. It is a member of the DIF and has contributed to the international standardization of decentralized identity and verifiable credentials. The Glacier Blockchain team has also co-founded the Web3 Identity Lab with the KILT Protocol team to work on scientific research and technical solutions from verifiable credentials to user privacy protection.

    We have been fascinated by the progress of latest cryptographic primitives such as zero-knowledge proof. We have learned the potential of the Distaff VM project regarding privacy protection and computation integrity through our frequent discussions with the author of the project. We truly believe the combination of a general purpose zk-STARK virtual machine and the Substrate framework will make the Starks Network a valuable player in the Polkadot/Kusama ecosystem.

    Project Detailsโ€‹

    Introduction to the Distaff VMโ€‹

    A high level architecture of the Distaff VM is shown as the following.

    distaff_overview

    The Distaff VM provides a set of assembly language which can be used to construct a general purpose computation into a program which can be interpreted by the virtual machine. The basic work flow of the VM is:

    a. Takes 2 inputs: a program and a set of inputs for the program;

    b. Executes the program with the given set of inputs;

    c. Outputs hash of the inputs, hash of the outputs generated by the program, and a STARK proof attesting to the correct execution of the program.

    Then the verifier can take the hash of the program, hash of the inputs, and hash of the outputs, and uses them to verify the STARK proof. As such, the user can prove to the verifier that she owns some secret data which, when used as the input of a program, can yield certain output. She never has to reveal the input data to the verifier; thus her privacy is protected.

    One way to automate this process is to set up a smart contract on the blockchain which can perform the proof verification. As such, a lot of real-world verification work can be moved on-chain and the users never have to give away their secrets for e.g. credential verification.

    Architecture of the Starks Networkโ€‹

    The overall system architecture and the basic work flow of STARK proof generation and verification on the Starks Network is shown as following.

    system_disgram

    a. A verifier will set up an on-chain smart contract with a target Distaff VM program embedded.

    b. A user will interact with the smart contact, get the program and generate a proof with their secret inputs using the Distaff VM embedded in the user client application (Step 1, 2 and 3).

    c. The user sends the hashes and proof data (results) back to the smart contract via a transaction (Step 4).

    d. The smart contract will verify the results using the Distaff VM built in the blockchain node binary, make a decision and update its state (Step 5 and 6).

    As such, the user has interacted with an on-chain smart contract without revealing their secret data. It should be noted that the Distaff VM will be made as part of the user client application for proof generation. It will also be made as part of the blockchain node binary and accessible to the on-chain smart contracts.

    Existing Problem and Our Solutionโ€‹

    It seems straightforward to perform step c in the previous section on a Substrate blockchain. However, it is actually not feasible and here is why. Compared to other zkp techniques such as zk-SNARK or Bulletproofs, one disadvantage of zk-STARK is the relatively large proof size. The typical size of a Distaff VM proof is around 100KB. It would be unrealistic to store all the proofs on-chain as the blockchain storage is kind of expensive.

    So, is there a way to store the proof data off-chain while we can still make use of them for zkp smart contract verification?

    Thanks to the Substrate framework, we have a tool to solve this problem. An off-chain worker (ocw) is a Substrate subsystem which can process off-chain data in an asynchronous way. It can perform non-deterministic tasks such as Web requests or CPU-intensive computations and write the computation results back to the chain as signed transactions. As such, we can have some stark data nodes in the system which will cache the proof data sent by the user in a local data store or even a decentralized data storage such as IPFS. The ocw will check the data store periodically, process the proof data, get the verification results and update the state of an on-chain smart contract with a transaction. This approach can solve the storage problem of off-chain proof data.

    But there are again issues as a result of this approach. What if a node runner tries to cheat with their proof? What if a malicious node sends back incorrect verification results intentionally? We have designed counter measures regarding these threat models and they will be unfolded as our project progresses. In the scope of this grant application, we will focus on the PoC where an on-chain smart contract interacts with the Distaff VM using proof data stored off-chain.

    We expect the teams to already have a solid idea about the project's expected final state.

    Ecosystem Fitโ€‹

    There are some existing projects which can be related to the Starks Network. In general, they fall into the following categories:

    • Blockchain projects which provide confidential computing service using a hardware Trustable Execution Environment (TEE). Phala Network and SubstrateTEE are good examples of such projects. The main difference is that we use zkp instead of hardware chips to provide similar functionalities. Our approach makes the Starks Network immune to hardware bugs/failures/backdoors in proprietary CPUs.
    • Zerochain is a Substrate based zkp blockchain project. The main difference from the Starks Network is that it uses zk-SNARK instead of zk-STARK VM as its zkp power house. The zk-SNARK is well known for its small proof size. But it requires a trust setup process to get started which limits its usage. In addition, the function of the Zerochain is focused on private transaction, while the Starks Network aims to provide zkp service for general purpose computations.
    • The Cairo project from StarkWare (inventor of the zk-STARK technology) announced a few days ago. As explained in the press release, "Cairo is the first production-grade platform for generating STARK proofs for general computation". The description of its functionalities have a lot of similarities to what our Starks Network have to offer. It is fair to say the Cairo project is a powerful counterpart of the Starks Network--only it is built in the Ethereum ecosystem. The whitepaper, documentation and related tooling are yet to come in the next few months (unsure if it is open sourced). And we will closely watch its development as it is exciting and inspiring to have more projects coming in the field of zk-STARKs application.

    Overviewโ€‹

    Milestone 1 - Liquid staked DOT tokenโ€‹

    In the grant program, the Stone Team aims to provide liquidity of staked tokens on Polkadot ecosystem, and the special LP token which bounds to staked assets, like DOT token. We are aware that there are multiple teams are actively working on Polkadot ecosystem and more exciting projects on the roadmap, we'll focus on DOT-bound staked assets like aDOT first for the milestone 1 We'll also provide an easy-to-use web based UI that connects to the chrome based DOT wallet, and user can buy/sell the index using their DOT tokens easily, this UI will be part of https://stonedefi.io

    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes. Once the node is up, it will be possible to send test transactions that will show how the new functionality works.
    0c.Testing GuideThe code will have unit-test coverage (min. 70%) to ensure functionality and robustness. In the guide we will describe how to run these tests
    0d.Article/TutorialPublish tutorials and documentation in different channels, e.g. Stone Medium and other social media platforms
    1.UI/UX for Stone PlatformUpdate and add a new UI component that allow user to buy/sell stone index using different crypto assets, DOT for milestone 1
    2.Indexed basket managementAn indexed basket management module is a set of Substrate pallet which allows creation and update the indexed basket, as well as mint and burn index token function
    3.DEX integrationWe will build the DEX trade function on top of another Polkadot Program PolkaDex

    Future Plansโ€‹

    Upon the completion of Milestone 1, the team will potentially add more functions like:

    Stone Index will be part of Stone Platform, and this grant program is the very first attempt of extent to Polkadot ecosystem in Stone Platform. The Stone team will continuously add more valuable instruments, and the team is aware that more and more teams and projects are rushing into Polkadot ecosystem, so we'll keep an eye on the new initiatives, and onboard those legitimate assets once they are ready

Council can elect curators that will manage platforms content. It is expected that council will drive the project towards more interesting and experimental use-cases than plain auctions of art - a lot of stuff can be tokenized and may be attractive for the community to be able to sell different item categories.

    There are several approaches to implementing the actual governance module.

    Part of the auction palletโ€‹

    This makes the most sense at the first sight because we can utilize the power of Substrate to implement governance via collectives, democracy and voting pallets. However, our plan is to make the auction pallet really flexible and introducing governance can pollute auctions with unnecessary complexity regarding the governance (and thus make it less re-usable for anybody who would like to implement another system on top of our pallet). Also, there are plans for having multiple instances of the auction pallet on chains supporting NFTs so it's also a question how we would keep only single instance of governance in this case.

    Separate palletโ€‹

    This seems like an ideal solution because it has a benefit of using Substrate but factors out all governance functionality to a separate pallet. Downside would be that each NFT platform where we plan to integrate our auction-pallet would have to integrate two pallets instead of one to their runtime.

    Smart contractโ€‹

    Smart contract approach has following advantages

    However, downside is obviously not exploiting great capabilities that Substrate offers and having to implement a lot of stuff by reinventing the wheel.

    Tokenโ€‹

    We have decided to use Basilisk as the home chain so the auctions will leverage Basilisk's fungible as well as non-fungible tokens for transfers and governance. As it uses FRAME's Uniques pallet it will be possible to easily migrate and reuse the solution on other Substrate based chains.

    Curatorshipโ€‹

    Curatorship is closely tied to the governance since only approved members can have elevated privileges over the system (e.g. vote on removal of inappropriate content). Any user can report offensive content to the curators. Curators then remove the content or reject the report. We will probably run a Discord/Telegram channel to open a discussion about a right way to do the curatorship and what kind of stuff is acceptable for public auctioning and what is not

    Content curationโ€‹

    Positive motivationโ€‹

    Users will be incentivized to provide a good quality content by either getting tips from the council for a good catch or fullfilling bounties which were announced by other uses. As an example, there can be a user who wants to own a digital art collectible but is not able to or does not have time to search for it. If another user provides such a collectible to the marketplace, they can be rewarded not only by the collectible price but a bounty on top of it.

    Negative motivationโ€‹

    On the other hand, we're aware the content needs to be moderated to some extent because of possible unsolicited character. In the first place we aim to combat this by starting with VIP auctions that will be pre-approved by the council before public launch. Eventually we plan to open the auction creation process a bit more and start to allow create auctions without council approvement based on gaining reputation by using our platform without violation of rules. Once our solution starts to offer these kind of public auctions for almost anyone to create, we want to introduce a penalty system to control that unsolicited content will be removed and the person who advertises it will be punished depending on the level of severity. The slash might be taken from a security deposit at the time user creates the auction.

    Offence levelContent propertyExamplePunishment
    1InappropriatePornographySlash up to 50% of the reserved funds for a specific purpose (e.g. auction) + up to 10% of total funds
    2OffensiveExplicit brutal content like violence/accidentsSlash up to 100% of the reserved funds for a specific purpose (e.g. auction) + up to 20% of total funds
    3HarmfulChild porn/Women abuseSlash up to 100% of the total funds

    Business Model Mechanicsโ€‹

    To keep on moving this project forward, we need predictable revenue streams to secure resources of different parts of our NFT marketplace such as content curation, new NFT content partnerships, and of course ongoing product development. We'll research applicable business models and go-to-market strategies that align with our overall vision of the NFT marketplace.

    Ecosystem Fitโ€‹

    We aim to build a feature-specific auction pallet that possibly integrates with already being developed NFT infrastructure projects and allows creating and bidding on NFT auctions of different auction types. The point is to provide easy integration to existing NFT implementations that can be re-used across the whole ecosystem. Also, there will be different auction types and some of them have never been implemented in the Polkadot space so it's definitely something that will push the whole ecosystem forward and we might even find some other means of token distribution models that can benefit all the projects (for example adjustments to the Dutch auction).

    Also, we are already in touch with several leading NFT projects within the Polkadot ecosystem and they are very interested in having an auction system on top of their platforms. For instance, we have discussed that with Kodadot and we definitely want to work together in the future.

    NFT integrationโ€‹

    There are multiple different approaches to NFT implementation on the market with no official standard set in stone yet on Polkadot. We want to keep our solution as flexible as possible and have the ability to be integrated with a broad spectrum of NFTs. At this point, the closest resemblance of an NFT standard we could find was the ORML by Acala so we started and will continue building based on this library. On the other hand it should be easy in the future to migrate the solution to a different kind of NFT implementation or a Polkadot standard.

    UPDATE 2021-09-28: The solution has been migrated from ORML to FRAME's Uniques pallet.

    Milestone 1: Implement Auction Type Generalisationโ€‹

    See Auction Type Generalization for definitions.

    Milestone 2: Implement New Auction Typesโ€‹

    See Candle Auction Type and Top-up Auction Type for definitions.

    Candle Auction Typeโ€‹

    Candle auction is a variant of the English auction where the last part of the auction is randomized in the sense that it can be concluded anytime. This prevents bidders from leaving their bids to the last few minutes or seconds and it's fairer in the internet environment where bots can bid on behalf of the buyers. The configuration of such an auction will be very similar to the English one.

    Candle Auction Type Diagram

    Top-up Auction Typeโ€‹

    This is a very popular auction type used by charities. Each participant will pay a "top-up fee" which is based on the bid he made minus the closest lower bid. This effectively means that each participant will pay the top-up fee except the first and the last bidder. The last bidder wins the auction, obtains the item, and only pays the item's price. We believe that bringing this kind of auction type enables entities to raise funds for good causes so that we can connect socially responsible projects with supporters and philanthropists.

    Top-up Auction Type Diagram

    Community engagementโ€‹

    We are well-positioned within the Polkadot ecosystem to create our own product since we started the Polkadotters community that is currently having over 4,000 members and supporters. Therefore we will have plenty of space to carefully test our product and receive valuable feedback from the community. We will also try to gather support from other Polkadot ecosystem projects since we already have a good reputation within a space and we are confident that we will be able to promote the project properly.

    Our progress will be regularly published on social media to gain enough attention and for the sake of transparency of the whole project.

    Our channels

    Future Plansโ€‹

    We're huge fans of NFT space and we do believe that the Polkadot ecosystem will benefit from having the feature-specific auctino pallet that can be able easily integrated into other NFT solution standards developed on Polkadot. Our end result should be a feature-specific pallet that could be plugged into other blockchain applications and an NFT auction marketplace application with DAO curated exclusive content. But this is only beginning, we believe that huge innovations are going to happen in the NFT space and we want to follow those changes as closely as possible to make our auction system thrive!

    SubDEX

    • Payment Address: 36RukKN8Qa1QTjsQqCfZ5CzrvAKVg2vro8

    Project Description ๐Ÿ“„โ€‹

    SubDEX is a decentralized cross-chain exchange based on AMM (automated market maker) protocol. This project was initially submitted to Hackusama. The SubDEX team's goal goes beyond what was produced in the hackathon. We aim to continue to build SubDEX and hope it becomes a parachain that connects to Kusama and Polkadot networks, so that other parachain assets can be exchanged on it with privacy in a decentralised way.

    Centralised Exchanges (CEXs) have grown exponentially in last decade, because

    1. demands for fiat to crypto asset exchange
    2. demands for assets exchange between different blockchain assets
    3. different blockchains are isolated from each other like islands in oceans

    Users have to rely on a middle man (CEX) to exchange different blockchain assets.

    DEXs have existed on Ethereum blockchain a few years, but they usually have low liquidity and bad user experience. Vitalik's research inspired Uniswap team and Uniswap's success inspired us. We think it is time for DEXs to disrupt CEXs

    Uniswap's success is exciting, but it is mainly used to only exchange Ethereum assets (ETH and ERC20 tokens). Some solutions such as REN exists for user to exchange BTC with Ethereum assets, but most of other blockchain assets cannot be traded on Ethereum DEXs. Furthermore, as AMM protocol evolves, we have seen that Uniswap V1 evolved to Uniswap V2 and Bancor evolved to Bancor V2, both old and new versions have to co-exist because the old version cannot be seemlessly upgraded to new version on Ethereum.

    Kusama / Polkadot's cross-chain protocol and on-chain upgrade make them the perfect blockchain to build a DEX. We are aware there are other DEXs such as Polkaswap and Acala being built now, however, SubDEX is designed to align with the substrate FRAME framwork and adds to the ecosystem with a set of pallets that are reusable and a interface for good user experience.

    The team met during the hackthon and have established strong inter-team relationships through a common goal - to provide a DEX that is built by, used by and maintained by the community.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Almost every substrate project has a need to process and query data. SubQuery is a open-source tool to provide a complete solution to this problem and will become core infrastructure for the Polkadot ecosystem. We expect it to solve how to Extract, Transform, Persist, and Query data intially, and then how to Connect and Present data in the future.

    SubQuery is NOT an ETL tool, the persisted data is minimized and shaped from the perspective of how it will be used.

    SubQuery aims to support all substrate-compatible networks.

    Project Detailsโ€‹

    In this proposal, we provide a complete workflow to create a live data query system.

    Step #1: Create a SubQuery projectโ€‹

    1. use @subql/cli tool we provide to create a SubQuery project
      • it is written in typescript
      • user needs to config the project, define a schema and implement mapping functions
    2. use @subql/cli to generate types from the given schema
    3. use @subql/cli to compile and pack the SubQuery project

    Step #2: Run an indexerโ€‹

    Prerequisites

    • A Postgres database
    • Non-archive full node. If storage query is used, then an archive node is required to extract chain data. OnFinality provides an archive node with a generous free tier that should be more than able to cover most cases.
    • A moderately powerful computer to run an indexer in the background

    Then start our @subql/node with the path of local SubQuery project as arguments, @subql/node will handle the rest.

    Step #3: Run a Query Serviceโ€‹

    We do have plan for a custom built graphql query service @subql/query, but in this stage we will use Harura to do the job.

    Componentsโ€‹

    Npmjs Packages to published:

    • @subql/cli
    • @subql/node

    Ecosystem Fitโ€‹

    The original intentions are different and that leads to different technical decisions.

    • These two projects are both created by a substrate-based blockchain team in order to fulfill the needs of their own chains in the beginning and then adapted into standalone projects.
    • The motivation of us is to make a tool that solves query demands of all substrate blockchains right from the start. We also plan to then provide a full managed and hosted service to lower the barriers of entry further.

    The differences:

    1. Secure execution of mapping functions are not a top concern for them, but is a hard requirement for us and will be supported in the proposal.
    2. We don't want to depend on 3rd party libraries in the core code of the project, libraries such as warthog used by Hydra.
    3. API access within the mapping functions will be supported
    4. Our proposal aims for OLTP, and allowing customisation of indexing process which are different from ETL like projects. The outcome of indexed data is that it is shaped for the need of its specific usecase, and be consumed by browser and mobile apps.

    Community engagementโ€‹

    We will publish a series of articles on Medium and videos demonstrating the usage of this tool too. We will engage with users in our community on Telegram.

    Future Plansโ€‹

    • With the help of this tool, anyone can create and run queries easily. But there're still issues for when a user wants to consume the query service in production, our intention to close this gap by providing a hosted service.
    • In regard to functionality, we also plan to support SubQuery composition and data subscription for users that use our hosted service.
    • Smart contracts including Solidity and ink! support are in our future roadmap.
    • We are intending to reach out to all major chain explorer teams and engage with the community to see how our service can benefit it.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    SubRelay is a no-code solution to build automation workflows on any Substrate-based chain. The application helps users to create their off-chain automated workflows by subscribing to on-chain events through the interface. We aimed to make the app easy for average users but remain a powerful tool for advanced users. With this in mind, we designed Subrelay to be generic and flexible with any use cases. Additionally, the SubRelay can integrate with any runtime of any blockchain building on the Substrate, such as Polkadot, Kusama, and Statemine.

    The app was motivated by our desire to monitor the on-chain events and send webhook requests to our internal system. We wanted to build a solution that not only can solve our problems but also benefit the entire ecosystem of Substrate/Polkadot. Our vision is to make SubRelay the most popular event relay service for any chain in the Polkadot ecosystem.

    As mentioned above, SubRelay can integrate with any Substrate-based chain, bringing a massive benefit to the Substrate/Polkadot ecosystem.

    There is a wide range of our target users, but we think there are a few main groups of the user:

    • Normal blockchain user: The interface of SubRelay is designed to support normal users who want to do a simple task such as watching the change in their balance by setting a notification.

    • Crypto experts: Although SubRelay's interface is easy to use to support normal users who need a simple workflow, it also is a powerful tool for experts. There is no limitation on what can build with SubRelay. For example, a defi farmer can monitor their liquidity pools, borrowing, and lending positions, or an NFT trader can watch their favorite collections' prices.

    • Developers/ Team: From the developer's perspective, there is no easy way to integrate an existing system with a blockchain. Our solution will help the teams save time and resources to focus on solving their business requirements instead of wasting their time building a service to integrate with the chain.

    Web3Go MoonPush looks similar to our project, but SubRelay is more generic and flexible. There are a few key differences:

    • SubRelay can integrate with any Substrate-based chain.
    • SubRelay supports subscribing to any runtime events.
    • SubRelay provides a highly customizable event filter and action configuration.
    • SubRelay has log systems that allow users to manage workflow performanceย by recording all success and failure pipelines.

    Subscript: Substrate smart contact written in AssemblyScript

    • Proposer: synote
    • Payment Address: bc1qzv5ljrt0sngjjnn25s4jzsu7qtts5d74cq8tz5

    Project Overview ๐Ÿ“„โ€‹

    We are intergrating AssemblyScript into substrate smart contract which is similar to parity's ink. It involve buillding substrate contract runtime api, builtin modules, and development sdk. we name the language and sdk as Subscript.

    Overviewโ€‹

    Subscript is a smart contract language written in AssemblyScript for substrate based chain. We will provide essential substrate api and builtin tools to support contract development.

    Similar to parity ink, Subscript is built on top of AssemblyScript and follow all AssemblyScript syntax. Subscript is more like a development kit with some builtin module and tools. As assemblyscript is easy to interact with TypeScript and JavaScript, Subscript is much more friendly for dapp developers.

    Project Detailsโ€‹

    Subscript is designed as standard AssemblyScript with builtin contract api. First of all, Subscript libray will provide basic contract pallet runtime api access.

    • contract runtime envionment
    • contract memory management
    • state storage access, set and get value by key.
    • event data generation and storage

    The Subscript library also add support for contract interaction utilties, including:

    • contract metadata generator
    • basic data structure: dynimic array, map, list,
    • user struct storage layout
    • account and balance interface
    • contract call abstraction
    • builtin utility fuctions

    The package will provide contract template and intergation tool with substrate node.

    There is no plan for EVM Pallet support.

    Ecosystem Fitโ€‹

    Some of the function of Subscript are similar to LimeChain's work of AssemblyScript Runtime, but they are made for different scenario. LimeChain AssemblyScript Runtime focus on building substrate runtime with wasm compiled from AssemblyScript. It involves building all the substrate runtime environment entry with AssemblyScript and other basic library. Subscript aims to implement all the substrate smart contract low level interface with AssemblyScript. Subscript also add support for basic contract lib and project template for easy development. We may benefit previous work from LimeChain such as SCALEcodec, runtime entry implemention.

    Milestone 1 โ€” Implement smart contract low level apiโ€‹

    • Estimated Duration: 2 month
    • FTE: 2
    • Costs: 2 btc

    In this milestone, all the basic substrate contract runtime api will be implemented in AssemblyScript. This stage will deliver a AssemblyScript package which provide encapsulation of current substrate contract api. With the AS api, contracts can be compiled to wasm and deployed on substrate contract node. We may benefit from the reference implemention of parity Ink and provide similar api.

    The AS package will cover the following substrate contract api:

    0a.LicenseApache 2.0
    0b.TestingThis milestone will have unit-test for all the following runtime api impemented. We will mock most of the contract runtime api to simulate host functions. Integration test will be delivered in next milestone.
    0c.DocumentationWe will provide both inline documentation of all the sdk api and basic code example that show how developers use the api.
    1.contract runtime environmentcontract builder and execution to initailize the contract code
    2.core typesadd core component: AccountId, Balance, Hash, Block
    2.storage accesscontract low level storage read and write with key
    3.object packing utiltyProvide user-defined data structure packing and unpacking method to storage access.
    4.memory manipulationImplement memory make and getter, setter
    5.contract event generationGenerate event from contract call
    6.contract call methodProvide method for make contract call.
    7.hash utilityMake digest of encoded input to generate hash image
    8.SCALE codecBuiltin codec functions to serialize and deserialize input. We may directly use LimeChain as-scale-codec implementation.
    9.example for demonstrationProvide ERC20 contract example to test on substrate node

    Future Plansโ€‹

    After the Subscript presentation , we may make our effort to bring more tool for contract development.

    A simulated contract sandbox similar to ganache is needed to debug and test contract.

    We may add more intergated tool and IDE packge for contract developer.

    Project Overviewโ€‹

    Overviewโ€‹

    Backgroundโ€‹

    The block explorer is the important portal for on-chain data visualization. It can record and count information such as each block, each transaction and address of different blockchain networks. The essence of the block explorer is to reasonably display native data and derived data to various users according to the actual situation of the blockchain network. The users of block explorer include at least: developers, users, token holders, miners, regulators, researchers, and people interested in blockchain.

    With the goal of building a multi-chain ecosystem, Polkadot has gradually become the preferred solution for many blockchain projects. As more and more blockchain networks join the ecosystem, users have higher and higher requirements for block explorer.

    The most influential block explorer in the Polkadot ecosystem is Polkadot native explorer. it provides a large and comprehensive blockchain explorer, any blockchain network built on The Substrate can apply for access, and supports one-click Toggle, which is currently the primary option for many ecological project. Its characteristics can be summarized as follows:

    1. Rich real-time data display. Provides the display of a large amount of data on blockchain such as blocks, validators, and community governance.

    2. Support wallet management. Contains most functions of the wallet, and supports wallet management functions such as account generation, import, and token transfer.

    3. Developer friendly. It contains a wealth of developer tools, and supports practical functions such as chain state query, transaction initiation, and RPC call.

    4. One-click import. All blockchains developed based on the Substrate framework basically implement the same set of basic interfaces, and the Polkadot.js App only needs to provide a websockets link to implement the import.

    But everything has two sides. The following inconveniences also exist behind such a powerful block explorer platform:

    1. Front-end resources are bloated and network latency is high.

    2. Since the web side of platform directly obtains and renders data through blockchain nodes, it leads to slower data reading speed.

    3. Likewise, on-chain resources are relatively precious, resulting in more meaningful statistics that need to be processed that cannot be kept on-chain. However, these statistics have a direct impact on user experience.

    Based on the above characteristics, Polkadot.js App is more suitable for the needs of developers and wallet-related operation scenarios. For more common query scenarios such as retrieving transactions, querying balances of wallet address, checking the basic status of the network, and querying miner information, the actual needs of users are "fast" rather than "more". Just like if you just want to buy a bottle of beer, then the convenience store in the community may be more suitable for your needs than the supermarket that is farther away.

    Polkadot.js App is like a large supermarket with a wide variety of products. However, for the simple daily needs of users, convenience stores (lightweight block explorer) will be a good complement to it. So is there a lightweight block explorer that is easy enough to use in the current Polkadot ecosystem? The following is the situation of our research.

    Current Solutionโ€‹

    Subscan is a block explorer that provides operations management services. It supports about 20 Substrate-based parallel chains and offers basic functions. At the same time, it also provides paid customization services for users who have higher API requirements. This model is more convenient for developers, however, the customization service fee can be as high as tens of thousands of USDT, and developers may abandon some functions due to financial concerns.

    Polkascan is an open-source block explorer that is relatively lightweight and simple in data display. However, through code analysis on its Github, it has limited capability in data processing since it doesn't have a database and cannot perform data analysis.

    In summary, we believe that there is a lack of a better open source lightweight explorer in the current Polkadot ecosystem. That's why we designed Substats - a lightweight block explorer framework. Different from Polkadot.js App, Substats provides lightweight components to reduce the dependence on the network and provides customized data display functions. And by building a stable background and database services to obtain more powerful data processing capabilities.

    Featuresโ€‹

    โ— On-chain data processing station: A processing station is built between users and the blockchain network, which includes a cache (database) layer and a computing (data processing) layer. The cache layer is responsible for pulling the data on the chain to the local database for storage. The computing layer is responsible for processing the on-chain data in the database, so that it can be combined into more meaningful data for users, such as historical data statistics, network-wide computing power rankings, etc.

    โ— Convenient data display and retrieval: Compared with reading blockchain network data through RPC nodes, it is more convenient and faster for the client's wxplorer to read directly in the database of the processing station built by Substats.

    โ— One-click construction: Learn from the features of Polkadot.js App. The Substats framework only needs to configure a small amount of information to achieve one-click deployment and startup. Significantly reduce development costs.

    โ— Modular UI components: The UI components of Substats are all decoupled, allowing developers to customize the development of UI components with low threshold.

    โ— Open source and security: Substats only provides completely open source code, and is not responsible for replacing management and operation services. All services are deployed and operated by the project party, avoiding trust costs.

    Project Detailsโ€‹

    We have designed a set of explorer modular components for the Substrate ecosystem, which can be used by stakeholders (such as miners and storage users) and other users.Polkadot, Kusama and Rococo will be supported in first version. Users can inquire about basic information in the network, such as space information, rankings, blocks, transactions, addresses, visual trend charts, etc. Substats is open-source and has flexible scalability in both network and its functionalities. Hence early-stage projects or individual developers can easily integrate our components based on their business needs. The data analysis module and custom components are the two core functions of Substats.

    High level designโ€‹

    Proposal architecture

    Figure 1: Proposal architecture

    โ— Data Processing: Data processing can be divided into the following steps: data acquisition, data parsing, and persistent storage. As a block explorer framework, Substats optimizes each process to reduce unnecessary workload and improve efficiency for developers. For example, it supports custom data acquisition; realizes the separation of data read and write through the buffer queue; supports various types of data acquisition methods: RPC communication of full nodes, P2P protocol of peer nodes, etc.

    โ— Data Rendering: In addition to providing developers with APIs for crawling block data and derived data, Substats also provides developers with a front-end framework which displays data such as block info, transaction info, and address info in a modular way, and each module can be customized. And Substats has a wealth of themes and icons to choose from.

    Typical exampleโ€‹

    Workflow

    Figure 2: Workflow

    1. The node service synchronizes the block data of the blockchain network. The node services here include full nodes of the network, third-party data retrieval services, etc.
    2. The data crawling module obtains block data from blockchain nodes. Substats supports full node, P2P node, local database and other types of node service connection, and supports custom data read interfaces.
    3. It writes the block data crawled from the node service to the buffer queue. The buffer queue is used to separate the process of crawling data and parsing data, and supports data integrity checking and exception handling.
    4. The block data is taken out of the buffer queue and sent to the parser in order.
    5. The parser parses the block data and writes it to the database in time. The parsing process is accelerated by concurrent execution.
    6. For general block data, Substats provides a series of database table structure that enables developers to use it out of the box. For custom Pallet data, developers need to define the relevant table structure.
    7. The front-end component periodically reads the relevant data in the database through the HTTP API to render the web page.

    This project makes up for Polkadot's lack of official PoS parachain templates. At the same time, it also makes up for the shortcomings of moonbean, because their Staking is very different from Substrate's Staking. This is more friendly to both developers and users. It is born for better use of substrate to develop PoS parallel chains.

    Ecosystem Fitโ€‹

    How does substrate-client-java fit into the ecosystemโ€‹

    We have identified that many teams dealing with both legacy and up-to-date Java systems need to define appropriate approaches to communicate with Substrate-based blockchains. For example wrapping the polkadot javascript client or trying to build their own implementation. We intend to make this work easier by offering to the community a ready to use and production ready library to be used in all Java application. We will use this solution ourselves in our production environment, since we have multiple applications running on different versions of Java platform that needs to communicate with the Polkadot ecosystem.

    Target audience and needs met by substrate-client-javaโ€‹

    With our solution we meet the need of any Java developer who needs to write new Java applications or adapt existing Java applications to communicate with a Substrate based blockchain.

    Other projects similar to substrate-client-javaโ€‹

    To our knowledge only one other project has tried to create a java library to communicate with Substrate-based blockchain, java-client. This project however was focused mainly on implementing what we indicated as "Declared known RPC sections and methods", and is targeting Java 11.

    Our solution targets Substrate instead of Polkadot, and is implemented with code generation technique, which brings a more generic, flexible and adaptable library. Our client is designed so that a custom pallet can be easily consumed without writing much code. And we support Java 8+ which still is the most popular version according to multiple surveys:

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    For this proposal, we'll be developing:

    1. Substrate Core RPC Polywrapper: Polywrapper in Rust that enables users to interact with substrate-based chains using any language on any platform.
    2. Substrate Signer Provider Plugin (js): Polywrap Plugin for Javascript host that allows signing of messages and transactions to be done using the polkadot-js browser plugin.
    3. Developer Documentation: Documentation showing developers how they can use the substrate core wrapper within their dapps and wrappers.

    In the future, we'd like to continue this work by developing:

    1. Token Balance Interface: Polywrap standard interface that defines common functionality for all pallets supporting "balances".
    2. Balances Implementation Wrapper: An implementation of the "Token Balance" interface that interacts with the Balances pallet's ABI.
    3. [Pallet ABI -> Polywrapper] Codegenerator: A code generator that generates Polywrap code based on a Pallet's ABI (leveraging the chain's metadata).
    4. Developer Documentation: Documentation showing developers how they can use the Balance wrapper, implement their own Balances implementation, and generate Polywrappers from pallet ABIs.

    Future proposals will be made for the above. Below we'll explain the work in its entirety.

    About Polywrap: Polywrap is a dev toolchain that enables easy integration of Web3 protocols into any application. It makes it possible for software on any device, written in any language, to read and write data to Web3 protocols.

    https://polywrap.io/#/

    Project Detailsโ€‹

    Polywrapper will be written in Rust and compiled to WASM so that it can be used by developers to call substrate methods by simply invoking graphql calls. We will deploy the Substrate wrapper to IPFS.

    Project heavily relies on the Polywrap toolchain and Polywrap team support.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

      Polywrap will allow polkadot dapp developers to integrate protocol logic into dapps in a simple, familiar way, regardless of their implementation language.

      Additionally it will enable a new "standardization layer" for dapps developers to use, enabling the aggregation of multiple similar-but-different chains. The first standard interface we'll be developing in the future will be the "token balance" interface. We will create an implementation of this interface for the Substrate Balance Pallet.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

      Our initial target audiences are dapp/wallet developers, as well as the broader web3 developer ecosystem since Polywrap is architected in a chain-agnostic way. We'll be working with the Talisman team to ensure the work we're doing aligns with their wallet's needs. We've already had preliminary conversations with them, and they're excited to work with the software we build for this grant.

      Additionally the Talisman team has confirmed that, if this Polywrap integration suites their needs like they/we think it will, they are willing to help contribute to the codebase(s) going forward along with ChainSafe and the Polywrap DAO.

    • What need(s) does your project meet?

      Polywrap meets the needs of dapp developers who want a simple way to integrate protocol logic into their dapps. The Polywrap integration experience should be extremely familiar to any develop who has integrated a Web 2.0 API. The dapp dev simply needs to add the Polywrap client into their dapp, and then they will be able to send GraphQL queries to an endpoint to execute protocol functions.

      Additionally, as previously stated, we've noticed that in the multi-para-chain future there is a need for another layer of standardization. This is because pallet ABIs may be different amongst multiple chains, but be effectively serving the same purpose (Tokens, AMMs, Profiles, Governance, etc). With Polywrap developers can create standard interfaces that can be implemented in many different ways, depending on the pallet being used. The dapp developer simply uses the standard interface methods/types, and doesn't have to care about the implementation details of the chain/pallet. We feel that this goes hand-in-hand with the "enriched metadata & typeinfo" feature that was recently merged.

      Lastly, it's worth noting that polywrappers can be downloaded and executed at run-time due to the security and portability of WebAssembly. This means that dapps using the "Token Balance" interface can potentially update themselves without having to be rebuilt, dynamically supporting new chains as they come online.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

      There are not other projects solving the integration issue today at the SDK layer. As previously mentioned, the "enriched metadata & typeinfo" PR solves the introspection problem at the chain-level, but there is more to do farther down the integration pipeline at the dapp level. This is where Polywrap will help.

    1.Schema DefinitionsDescribed below
    2.signer-provider Polywrap Client JavaScript PluginDescribed below
    3.rpc-wrapper WrapperDescribed below

    NOTE: 2 & 3 can be developed in parallel once schemas are defined.

    1. Schema Definitionsโ€‹

    There will be 2 Polywrap schemas:

    • signer-provider - Low-level interface for accessing the application's configureable signer / provider.
    • rpc-wrapper - Higher-level interface for interacting with a substrate based chain. This depends upon on an implementation of the substrate-signer-provider interface above.

    To get a better idea of what this "separation of concerns" looks like in practice, please refer to this example specification for the Polywrap <> Near integration that's actively being developed.

    2. signer-provider JavaScript Pluginโ€‹

    Plugins, in the context of Polywrap, are a special type of wrapper. Instead of being run as WebAssembly, they run as native modules in the application's language (ex: JavaScript). This allows the wrappers to access the application's native capabilities (ex: filesystem access), unlike WebAssembly wrappers which are run within their own nano-process sandboxed.

    The Substrate signer-provider plugin will enable the rpc-wrapper to:

    • Get all available accounts within the application's wallet (Keyring).
    • Sign arbitrary messages.
    • Sign transaction payloads.

    Polkadot.js will be used as the backing Keyring, enabling developers to use the browser-based wallet provided by the Polkadot.js extension, or additionally use a FileStore which can be used to load a wallet from the filesystem.

    The plugin would typically be instantiated and configured when instantiating the Polywrap Client, like so:

    import { substrateSignerProviderPlugin } from "substrate-signer-provider-plugin-js";
    import { PolywrapClient } from "@polywrap/client-js";

    const plugin = substrateSignerProviderPlugin();

    const client = new PolywrapClient({
      plugins: [{
        uri: "ens/substrate-signer-provider.chainsafe.eth",
        plugin
      }]
    })

    // Now we can use the above client to invoke the RPC wrapper,
    // which requires "ens/substrate-signer-provider..." as a dependency
    const accounts = await client.invoke({
      uri: "ens/substrate-rpc-wrapper.chainsafe.eth",
      method: "getSignerProviderAccounts"
    });

    Additionally, users can configure the plugin with their own SignerProvider instance, like so:

    import {
      substrateSignerProviderPlugin,
      KeyringSignerProvider
    } from "substrate-signer-provider-plugin-js";
    import { Keyring } from "@polkadot/ui-keyring";
    import { FileStore } from "@polkadot/ui-keyring/stores";

    // Load keystore from a directory
    const filestore = new FileStore("/path/to/keystore/dir");

    // Create your own keyring
    const keyring = new Keyring();

    // Load the keystore into the keyring
    keyring.loadAll({ store: filestore });

    const plugin = substrateSignerProviderPlugin({
      provider: new KeyringSignerProvider(keyring)
    })

    To get an idea of what the substrate-signer-provider schema might look like, please see the Near plugin's schema here.

    3. rpc-wrapper Wrapperโ€‹

    The Polywrapper is a set of WASM modules that contain the bulk of the logic needed to interact with substrate based chains. The Polywrapper calls the aforementioned JavaScript Plugin only when necessary to perform signing tasks.

    A call to the Polywrapper might look something like this (TS/JS application):

    const result = await client.invoke({
      uri: "ens/substrate-rpc-wrapper.chainsafe.eth",
      method: "chainGetBlock",
      args: {
        url,
        number: 0
      }
    });

    if (!result.ok) {
      handleError(result.error);
      return;
    }

    const blockOutput = result.value;

    Or by using the Polywrap toolchain's application codegen, you can have this be fully typed like so:

    import { Substrate_Module, Substrate_BlockOutput } from "./wrap";

    const result = await Substrate_Module.chainGetBlock({
      url,
      number: 0
    }, client);

    if (!result.ok) throw Error("...");

    const output: Substrate_BlockOutput = result.value;

    The rpc-wrapper exposes the following interface that maps closely to the default Substrate node RPC:

    • getSignerProviderAccounts
    • chainGetMetadata
    • blockHash
    • genesisHash
    • chainGetBlock
    • constant
    • getRuntimeVersion
    • getStorageValue
    • getStorageMap
    • getStorageMapPaged
    • rpcMethods
    • accountInfo
    • getNonceForAccount
    • palletCallIndex
    • sign
    • send
    • signAndSend

    We will be heavily leverage existing Rust crates in the substrate developer ecosystem to implement the wrapper detailed above.

    Future Plansโ€‹

    As stated above, we'd like to continue to build upon the work done within this proposal, by enabling multi-chain token balance aggregation (through the use of Polywrap interfaces).

    We hope that with this work complete, a team like Talisman will be able to continuing using the tooling we've developed to fully realize their vision of having a fully featured multi-para-chain wallet.

    The work created by this grant will be stewarded by the ChainSafe & Polywrap DAO teams, as well as the Talisman team if they decide to build upon what we've created.

    Long term plans and the target users of such an applicationโ€‹

    The target users would definitely be beginners and even people that wanna play a bit and not really start a production-ready blockchain. Experienced blockchain devs beginning to build a project with Substrate are probably familiar with how to start, and whoever has to deep dive into the code so they are not the ones that will benefit the most. We didn't consider the possibility of online chain running in this phase of the project, but it could be an option for some future version. Looking long term, this GUI would be the place for everyone to quickly get informed on runtime pallets so it should be periodically updated with new information. So the primary purpose is educational but also promotional. We added in the deliverables features focused on education such as:

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    SubVT Telegram Bot is an upgrade for the existing Helikon Polkadot/Kusama 1KV Telegram Bot to support all validators on Kusama and Polkadot with increased functionality and performance.

    Future upgrades aim for adding support for other proof-of-stake (PoS) Substrate-based networks such as HydraDX, Darwinia (Crab), Edgeware and more, and Telemetry data access to support more real-time node data and notifications.

    The 1KV Bot currently serves 221 out of 359 valid nodes on Kusama and 90 out of 129 valid nodes on Polkadot. Relatively high adoption rates (61% on Kusama and 69% on Polkadot) with very little announcement have resulted in our interest in extending the bot's support to all Kusama and Polkadot validators, and other Substrate-based PoS networks in the future.

    This upgrade consists of migrating the bot to use the backend services and storage of SubVT (Substrate Validator Toolkit), which is an under-development native mobile application project for iOS and Android phones, tablets and wearables, supported by the Kusama Treasury.

    Project Detailsโ€‹

    The 1KV Bot currently has a number of issues such as:

    • No support for validators outside the 1KV. It's also not possible for it to support networks other than Kusama and Polkadot in its current state.
    • New nomination notification doesn't work for nested calls such as multi-sigs, batch calls and proxied calls. It only works for top-level nominate extrinsics.
    • /stakinginfo command displays only an overview of the nominations backing the validator. The command response is slow on Kusama and even slower on Polkadot since it fetches and indexes the nomination data for the validator after every command call.
    • No account age information.
    • No chart for 1KV rating history.
    • No 1KV score information.
    • Missing notifications for:
      • Lost nominations.
      • validate extrinsic.
      • On-chain identity change.
      • Payouts.


    Current state of the 1KV Bot

    SubVT backend, under development for the SubVT mobile applications, is near its first-phase completion and can provide very fast data access required by the current 1KV Bot functionality and more. Below is a diagram of the proposed upgrade for the 1KV bot to utilize the SubVT backend services.


    Proposed upgrade

    SubVT backend is being developed in Rust. Proposed upgrade for the bot is going to improve and re-structure the current Javascript codebase to have the following modules:

    1. Telegram Bot API communication component.
    2. Information services component, which serves the commands sent from the user device.
    3. Notifier component, which delivers notifications as Telegram messages to the user's phone through the Telegram Bot API.


    SubVT Telegram Bot components

    Below is a list of commands that the bot will have after the upgrade.

    CommandDescription
    /validator-infoComplete chain data and (optional) 1KV data about the validator.
    /nominationsAn overview of the active and inactive nomination data. Number of nominators and total amounts.
    /nomination-detailsBreakdown of all active and inactive nominations. Includes nominator addresses and identities and number of other nominees per each nomination.
    /rewardsA chart that displays the total rewards earned by the validator per month and the total amount earned.
    /payoutsA chart that displays the total rewards paid out by the validator to nominators per month and the total paid-out amount.
    /settingsNotification settings.
    /addAdd a new validator to the chat.
    /removeRemove an existing validator from the chat.
    /helpA list of commands and their descriptions.
    /aboutDevelopment, codebase and contribution details.

    And below are the list of notifications after the upgrade:

    • New notifications:
      • New nominations in batch, multi-sig and proxy calls.
      • Nomination lost.
      • New validate extrinsic.
      • Identity or parent identity changed.
      • Payout call for an era, or multiple eras in a batch call.
    • Existing notifications:
      • Active set inclusion and exclusion.
      • Block(s) authored.
      • Validator chilled.
      • Offline offence committed.
      • Commission changed.
      • Controller changed.
      • 1KV-related.
        • Validity changed.
        • Rank changed.
        • Binary version changed.

    Ecosystem Fitโ€‹

    There are currently two more bots for the Polkadot and Kusama validators, both production-level and robust. One is by CryptoLab, and the other by Ryabina, both with Kusama and Polkadot versions.

    Ryabina bot is a more generalized one that supports configurable alerts for all extrinsics and events, yet it doesn't provide more validator-specific functionality such as in-chat reward reports, and the configuration is not very user-friendly due to the generalized nature of the solution. It also doesn't support 1KV data.

    CryptoLab bot is a validator bot with the strength of Telemetry support, yet it's also missing the in-chat reports and 1KV data.

    Team's experienceโ€‹

    I am a software developer with a bachelor's degree in Computer Science and 20 years of experience in development and leading. After a series of positions mostly in enterprise software development settings, I focused on native mobile development for iOS and Android between 2012 and 2019, in which year I was introduced to the world of blockchain and cryptocurrencies when I got hired by Tari. For a duration of 1 year and 8 months I led the development of Aurora, the Tari cryptocurrency wallet for Android and iOS. The app got received very well by the Tari community thanks to its lean, eye-pleasing design and simple UX. I learned a lot at Tari about how blockchain systems work and the cryptocurrency ecosystem in general. Working with a product management team thatโ€™s super-focused on usability and simplification gave me a perspective on the value of good UX and UI in a field thatโ€™s notorious for its technical difficulties for the not-so-technical users.

    After my time at Tari I got interested in Polkadot and Kusama ecosystems and started running a Kusama validator enrolled in 1KV. I developed the Kusama 1KV Bot just to scratch my own itch, then ported it to Polkadot. After experimenting a bit with Substrate storage and RPC interface, I developed the idea of SubVT and prepared a treasury spending proposal for the project, which got accepted by the Kusama council. I have been working with Klad, supervising the UX and UI design for the project, which is now complete. I've also been working on the SubVT backend, which is also near completion, bringing SubVT to its second stage: Android and iOS applications development.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Sukhavati is a decentralized cloud service network focused on storage. It uses the MASS Proof of Capacity (PoC) protocol as its consensus protocol so that it can reuse existing PoC capacity power and quickly establish a strong consensus layer. The MASS PoC consensus algorithm is very energy efficient. After the initialization operation, it requires only a small amount of computing and IO resource consumption to maintain high security consensus, allowing most resources to be used for other meaningful work.

    Currently the MASS PoC network has a total of about 230PB in capacity power, making it the second-largest PoC network. Sukhavati takes PoC as the entry point. After incorporating a wide range of PoC miners into the consensus network, Sukhavati will continue to build the needed infrastructure to serve the Web3.0 ecosystem on these PoC devices, taking full advantage of idle computing and bandwidth resources and truly decentralized network topology. Sukhavati eventually intends to build a decentralized data access gateway that covers both Web3.0 and Web2.0 storage services and that provides unified data storage, retrieval, and management services that can meet various local compliance requirements for Web3.0 applications.

    After completing the first version (which is based on the original codebase) and idea validation, Sukhavati plans to migrate to the Substrate framework (planned for Q2). The powerful and flexible features such as off-chain workers, on-chain governance and runtime upgrade provided by Substrate can bring Sukhavati great convenience and enable us to easily develop the storage and content distribution functions in the future steps.

    While enjoying all these features, we would like to give back to the community by providing a PoC Module for Substrate based on the MASS PoC consensus protocol, so that any blockchain developed based on Substrate can choose to use this module to implement PoC consensus and be able to reuse existing MASS PoC capacity power. This โ€œpiggybackingโ€ allows them to quickly have the same underlying device resources and potential influence as we do, thereby further exploiting the idle resources of the vast number of PoC mining devices. Through the implementation of this module, we hope to establish a connection between the substrate and the PoC ecosystem, giving web3.0 builders more options and room for imagination.

    Project Detailsโ€‹

    Plot Algorithm and Capacity File Importโ€‹

    The plot algorithm will generate two HashMaps, of which the latter one is kept as the capacity file.

    The plot process is as follows:

    1. Generate a root_key through secp256k1/ECDSA
    2. Using BIP-44 to derive child key pairs (pk, sk) from the root_key
    3. Set a BitLength and runs Plot algorithm with pk and BL as follows:
      • Generate a unique ID = doubleSHA256(pk) of the capacity file
      • For each x in [0, 2^BL-1], calculate y = SHA256(โ€˜MASSโ€™||ID||x). Generate a HashMap A with y as the index and x as the value
      • For each index y in HashMap A, flip each bit of it to get yโ€™, use yโ€™ as the index to find the corresponding xโ€™
      • For each x in [0, 2^BL-1] and corresponding xโ€™, calculate z = SHA256(โ€˜MASSโ€™||ID||x||xโ€™). Generate the HashMap B with z as the index and (x, xโ€™) as the value
    4. Use HashMap B as the efficient capacity

    The import method can be derived from the above process:

    1. Import the existing root_key from the mass miner
    2. Load the existing capacity file
    3. Derive child keys from root_key and match the public keys with the ID of the capacity files
    4. We can now use these existing capacity files for our own PoC consensus

    PoC Consensus Engineโ€‹

    Block Productionโ€‹
    1. Get challenge c from previous block
    2. The miner tries to find (x, xโ€™) and its corresponding BitLength and ID from HashMap B that satisfies:
      • cuthash(c, bl) == cuthash(SHA256(โ€˜MASSโ€™||ID||x||xโ€™), bl)
      • cuthash(y, bl) == flipped(cuthash(yโ€™, bl)), where y = SHA256(โ€˜MASSโ€™||ID||x) and yโ€™ = SHA256(โ€˜MASSโ€™||ID||xโ€™)
    3. If the above proof is found, the miner then calculates quality = (2^BitLength * BitLength ) / [256 - log2(H)], where H = SHA256(block_timestamp // slot_length, x, x', height)
    4. If the quality is higher than difficulty, the miner produces the block, creates the proof sig and signs the block.
    Block Validationโ€‹

    When a node receives a new block, it verifies all the signatures and PoC proof as follows:

    1. Verify the block signature and capacity proof signature
    2. Get PoC proof (x, xโ€™, bl), publickey pk and challenge c from block header and verify if they satisfy:
      • cuthash(c, bl) = cuthash(SHA256(โ€˜MASSโ€™||doubleSHA256(pk)||x||xโ€™), bl)
      • cuthash(SHA256(โ€˜MASSโ€™||doubleSHA256(pk)||x)) = flipped(cuthash(SHA256(โ€˜MASSโ€™|| doubleSHA256(pk)||xโ€™)))
    3. Calculate quality of the proof, and verify if itโ€™s higher than difficulty
    Difficulty Adjustmentโ€‹

    The desired block time is maintained by the following difficulty adjustment algorithm on every block:

    diff = parent_diff + parent_diff // 2048 * max(1 - (new_block_timestamp โ€“ last_block_timestamp) // 10, -99)

    Fork Choiceโ€‹

    When there is a potential new best chain, the node checks the following rules in sequential order to make the choice:

    1. The one with greater total difficulty
    2. The one with a better proof quality
    3. The one with an earlier block timestamp
    4. If all the above conditions are the same, choose the one with a smaller block hash

    Ecosystem Fitโ€‹

    The PoS/PoC consensus mechanism is starting to attract more attention with the rise of Chia. We notice that there are some other teams who are also building PoS/PoC consensus module for substrate, such as Subspace. The main difference between our protocols is that we are not trying to create a new PoC algorithm from scratch. What we want to do is to compatibly reuse the existing PoS/PoC consensus powers to form our own consensus layer and promote our blockchain to these miners, so that we can utilize their idle resources.

    In this proposal, we hope to make this capability of reusing PoS/PoC consensus power available as a substrate pallet. We believe some connection can be established between the substrate ecosystem and the PoS/PoC ecosystem, bringing more options and resources to Web3.0 builders.

    After establishing the underlying infrastructure, we hope to serve the Polkadot ecosystem as a parachain or parathread and provide a data access gateway for all Web3.0 DApps.

    Overviewโ€‹

    Sunrise is building a decentralized protocol on a dedicated Polkadot parachain. We will enable deep liquidity starting with support for tokens on Sunrise Chain, Ethereum, and all parachains. Sunrise will support additional blockchains in the future.

    Our Decentralized EXchange (DEX) uses a bonding curve factory which supports liquidity pools for unpegged tokens such as ETH,DOT, LINK, ACA etc. Sunrise will support stable coin pools offering very low slippage and fees (e.g. DAI-USDT) and in the future stable coins that have different pegs (e.g. srsUSD-srsCNY).

    Sunrise Chain Vision Deployment

    The first phase of the project will be built and deployed on a parachain via Rococo. Our standalone parachain Sunrise Protocol Daybreak will be the precursor. Sunrise is also evaluating the ability to deploy an Intrachain DEX (running on our partners) parachain, this will be done either publishing a DEX crate, updating ORML libraries, or directly contributing to partners codebase with a pull request to their repository.

    Polkadot Ecosystem Benefits

    Sunrise protocol lays the foundation for the seamless exchange of assets, efficiency of stable coin transactions and advanced aggregation. Our product will attract the decentralized finance (DeFi) community and provide more liquidity that helps drive increased adoption for the Polkadot Network. The DEX is multi-platform and bridges across parachains allowing the community to access the latest protocols and initiatives. Sunrise has identified numerous gaps to capitalize on, in relation to the infrastructure of the most popular decentralized exchanges, which includes liquidity pool customization, limit order functionality and compliance functionality.

    Why are we creating this project

    This project provides a foundational layer for the Sunrise Protocol.

    Our team consists of founders, researchers, builders and strategists for blockchain and decentralized finance. We have built a layer 1 blockchain at Harmony (public blockchain with sharding and open staking), have launched private permissioned chains on ethereum and hyperledger fabric and have been actively involved in the Decentralized Finance community. We have chosen to build this project on Polkadot because Substrate allows us to focus on the Protocol and business logic. We feel the Partners in the ecosystem are laying the foundation for interoperable decentralization and we want to contribute to the community.

    Project Detailsโ€‹

    Please see this product overview presentation and Sunrise Protocol Whitepaper for an overview of the Sunrise Protocol vision.

    This Project is specifically for the Sunrise Dex Factory which is a foundational component for the Sunrise Protocol

    The Sunrise Decentralized Exchange (DEX) combines the use of multiple bonding curves and price oracles to support liquidity pools for unpegged tokens, and stable coin pools. Below is an excerpt from the Sunrise Protocol Whitepaper

    3. Sunrise DEX Factoryโ€‹

    The Sunrise DEX Factory will support the creation of Liquidity Pool Contracts. The bonding curves for these liquidity pools, will be slightly different depending on the use case. Each exchange contract can be configured to the specific needs of the liquidity pool.

    3.1 Sunrise Factory/Registry Contractโ€‹

    All contracts will have a uniform interface for liquidity management and swap management. Thus abstracting away the underlying complexity from liquidity providers and traders, giving them a uniform mechanism to interact with all Sunrise liquidity pools.

    Below is a list of the configuration parameters input into the factory contract when creating an exchange contract.

    Sunrise Protocol Seven Key Parameters

    1. T Token Weight : Weight of Token in the Pool
      • Tokens: T. Assume there are n type of tokens in one liquidity pool, we denote them as (T1,T2,... Tn).
      • weight parameter: Wi(0<=Wi<=1) is the parameter of token i in our model, which is a constant defined when creating the pool. We always assume the sum of Wi =1.
      • initial balance: (x1,x2,...,xn) are the initial amounts a liquidity provider puts into a liquidity pool.
    2. epsilon Fees : Liquidity Provider and Protocol Fees
    3. beta Depth : Depth of Pool before slippage occurs
    4. Delta Slippage: The rate at which price slippage increases
    5. Alpha Max Min: Maximum and Minimum Token allocation for each reserve
    6. lambda Dynamic fees : Unbalancing Penalty Fees
    7. k Market Price Alignment: Alignment of the Bonding Curve with Price Oracle

    Sunrise Bonding Curves The three types of bonding curves use the following variables

    3.1 MultiToken Bonding Curve (1,2)

    3.2 StableCoin Bonding Curve (1,2,3,4,5,6)

    3.3. Proactive Bonding Curve (1,2,3,4,5,6,7)

    There will be default values for each of these parameters based on the Bonding Curve Type.

    When not utilized the variable will be set to a default value having a nonconsequential effect.

    Sunrise Protocol Overviewโ€‹

    Sunrise Protocol is creating an open decentralized financial framework. Sunrise is building a complete suite of financial tools and non custodial services within a compliant framework . This will be done in a trustless decentralized environment. With the goal of disrupting and streamlining current solutions offered by Centralized Exchanges and International remittances.

    The following information is a short summary of the other features of the protocol

    Sunrise Bridge is used to create a multi-platform, multi-asset protocol using cryptocurrencies (tokens) as building blocks. We will start with Polkadot parachains, ERC-20 tokens and then other blockchains.

    Once the primitives of a multi-platform, multi-asset DEX have been realized, decentralized financial protocols can leverage this for their liquidity needs.

    Sunrise Protocol will then add limit orders, a compliance framework and smart wallet functionality to give cost effective alternatives to Centralized Exchanges and International remittances.

    Below are the high level modules that can be integrated into the Sunrise Ecosystem. A number of these will be implemented by our partners and the community, some of which may be subsidized by Sunrise Protocol grants.

    Sunrise Ecosystem

    Ecosystem Fitโ€‹

    Sunrise Protocol is building an open decentralized framework. This grant application is for the Sunrise DEX, a sub-component of the larger Sunrise Protocol.

    We have done a comprehensive review of the other DEX projects which include Polkaswap, Reef, Mangata, HydraDx, Polkadex, Subdex. We see there are gaps in the current DEX Approaches, these include stable coin support, limit order functionality and compliance functionality. We feel that these DEX projects cannot be leveraged as part of our protocol due to the mentioned gaps and the different technical approaches.

    We are the only protocol to offer multi-asset pools, optimized stable coin support, multiple bonding curves, adjustable transaction fees and limit orders. We combine this with bridging capabilities for multi-platform support, limit order capabilities, combinatorial staking for better rewards, synthetic asset support, a compliance framework and smart wallet functionality to drive mass adoption.

    This application is specific to the DEX Pallet and lays the foundation for the larger vision which can be seen in our draft white paper.

    DEX Evolutionโ€‹

    Sunrise Reference Protocols

    The following protocols offer specific functionality and are often leaders in their respective areas. The points below walk through a chronological evolution of DEX and cross-chain capabilities.

    • Uniswap introduced a simple bonding curve supporting two token liquidity pools.
    • It later introduced itโ€™s UNI token which is now table stakes for all Decentralized Exchanges, Sunrise Protocol extends this combining trading, protocol and liquidity balance rewards.
    • Multi Asset Pools were introduced by Balancer and adopted by Curve who introduced the first bonding curve to support stable coins.
    • Price Oracles being utilized by Automated Market Makers are being evaluated by Sunrise and DodoEx wrote a good white paper about the topic.
    • Sunrise protocol adds to this with multipe bonding curves which supports multi asset pools, stable coins, and traditional tokens.
    • Our Liquidity Providers can set the transaction fees when creating a Liquidity Pool similar to Balancer and Curve.
    • We also introduce limit orders powered by our unique off-chain worker capabilities.
    • Polkadot and Ethereum are supported initially with more platforms to come powered by our integrated bridging technology.
    • Reef and PolkaDex are also building on Polkadot which provides the ability to create dedicated parachains.
    • A Compliance Framework will be leveraged by Sunrise Protocol to provide cost effective solutions which compete with Centralized Exchanges and International remittances.
    • Smart Wallet Functionality will also be provided to simplify the user experience and drive mass adoption.

    Additional Informationโ€‹

    Work done so far has included research and prototyping.

    No other teams have contributed to the project.

    This is Sunrise Protocol's first grant application. However John wrote a previous application for a DEX Pallet. The original application has been archived and the vision has been refined based on feedback from David Hawig and knowledge gained working on substrate over the past months by the Sunrise Protocol team.

    Sunshine Keybase

    • Proposer: 4meta5

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    sunshine-keybase implements Keybase's Local Key Security to associate a set of keys with a UID and manage this set of keys to sign and authenticate messages on the user's behalf. The implementation uses a Substrate runtime to enforce the rules of interaction with the keystore, especially as it pertains to revoking keys for a provisioned storage device.

    The project provides a usable keystore for local first applications using substrate. The sunshine-identity pallet provides structure to control a set of keys with a UID and track storage metadata associated with the given UID. The client uses ipfs-embed to store sensitive data offchain and encrypted on the local hardware. The sunshine-chain pallet uses the same stack to coordinate storage of chain data amongst a closed set of clients.

    We believe sunshine-keybase provides a reusable identity architecture for other projects in the Web3 space. Moreover, the sunshine-chain client and pallet demonstrate minimal design to set and enforce the storage of offchain data among a permissioned set of clients. This infrastructure will prove useful to substrate projects that need to coordinate and enforce private network storage of data offchain.

    Project Detailsโ€‹

    The project includes two pallets and a Flutter UI for Android.

    Chain Palletโ€‹

    The chain module is a reusable abstraction for building private proof of authority chains using ipfs and using substrate to provide authorization and consensus on the current head of the chain. When authoring a block on ipfs a race condition can occur. Due to substrate providing a total order of transactions only one transaction will succeed in updating the head of the chain, the other client will create a new block on the head of the chain and retry the failed operation.

    chain_module.svg

    Keybase Palletโ€‹

    The keybase identity module manages the user's chain that stores the user key, device keys, password and social media accounts using the sunshine chain pallet. Private data shared between devices is encrypted with the user private key. When a new device is provisioned a key is generated locally on the device, and a provisioning protocol is used to communicate between the new device and the provisioning device.

    keybase-module.svg

    Password changes are stored encrypted in the user chain. When a device receives a block with a password change it reencrypts it's local device key using the new password. This ensures that the user only needs to remember one password.

    Social media accounts are linked to a chain account, by submitting a proof in the social media profile and on the user's chain. Other users can find the on chain account on the social media page and verify that they are both controlled by the same cryptographic identity. This allows us to use github usernames as aliases without compromising the decentralized nature or security that blockchains provide. While resolving the social media account to an on chain identity requires the service to be online, already resolved identities are stored locally. This means that even if github is offline, transfers to already verified github accounts can be performed.

    Flutter Android UIโ€‹

    The Flutter UI allows Android users to initialize a local keystore and device identity using the sunshine-identity pallet. It allows the user to initialize the keystore, set a passphrase, and change the passphrase. The UI also allows the user to paste links to github gists to prove ownership of github accounts.

    Ecosystem Fitโ€‹

    There are other approaches to creating an identity graph, but we have yet to find another substrate project that implements device-oriented key revocability. The native keystore leverages ipfs-embed to store sensitive data in an encrypted form on the local hardware. Over time, we expect ipfs-embed to evolve with the needs and requirements of users.

    The current design coordinates the storage of private offchain data on permissioned client networks. Our project will use this identity infrastructure for sharing encrypted messages and backing up encrypted files, privately and within teams with membership tracked transparently on-chain.

    Development Roadmap ๐Ÿ”ฉโ€‹

    This section should break the development roadmap down into milestones and deliverables. To assist you in defining it, we have created a document with examples for some grant categories here. Since these will be part of the agreement, it helps to describe the functionality we should expect in as much detail as possible, plus how we can verify and test that functionality. Whenever milestones are delivered, we refer to this document to ensure that everything has been delivered as expected.

    Below we provide an example roadmap. In the descriptions, it should be clear how your project is related to Substrate, Kusama or Polkadot. We recommend that teams structure their roadmap as 1 milestone โ‰ˆ 1 month.

    For each milestone,

    Milestone 1 To make changes to pallet_supersig and apps frontend so that it is up to scratch with system chain level use, accepted by polkadot-js apps, and prepared for Fellowship review.

    Details for pallet:

    We will likely be making a limit on call data size and a cap on the number of "live proposals" there can be per chain.

    Limit Call Data Sizeโ€‹

    1. Limit call data size: Introduce a maximum call data size limit in the configuration trait. This limit can be set to a reasonable default value, which can be changed as required. Users will be prevented from submitting call data exceeding this limit:
    #[pallet::config]
    pub trait Config: frame_system::Config {
        // ...
        /// The maximum size of call data allowed (in bytes).
        #[pallet::constant]
        type MaxCallDataSize: Get<u32>;
        // ...
    }
    1. Check call data size: Before storing the call data in create, approve, and other relevant functions, ensure that its size is within the specified limit.
    // In the `create` function
    ensure!(
        call_data.len() <= T::MaxCallDataSize::get() as usize,
        Error::<T>::CallDataTooLarge
    );

    // Similarly, add checks in the `approve` and other relevant functions.

    1. Add a new error variant for oversized call data:
    #[pallet::error]
    pub enum Error<T> {
        // ...
        /// The call data size exceeds the maximum allowed limit.
        CallDataTooLarge,
        // ...
    }

    Limit Number of Live Proposalsโ€‹

    1. Add the LiveProposalMaximum associated type to the pallet's Config trait:
    pub trait Config: frame_system::Config {
        // ...
        type LiveProposalMaximum: Get<u32>;
        // ...
    }
    1. Add a storage item to track the number of active proposals for each Supersig account:
    #[pallet::storage]
    #[pallet::getter(fn active_proposals)]
    pub type ActiveProposals<T: Config> = StorageMap<_, Twox64Concat, SupersigId, u32, ValueQuery>;
    1. Modify the submit_call extrinsic to check the number of active proposals before allowing a new one:
    #[pallet::weight(T::WeightInfo::submit_call())]
    pub fn submit_call(origin: OriginFor<T>, supersig_id: SupersigId, call_data: Vec<u8>) -> DispatchResultWithPostInfo {
        let who = ensure_signed(origin)?;
        // ...

        let current_active_proposals = Self::active_proposals(supersig_id);
        ensure!(current_active_proposals < T::LiveProposalMaximum::get(), Error::<T>::TooManyActiveProposals);

        // ...
    }
    1. Increment the number of active proposals for the Supersig account when a new proposal is submitted:
    ActiveProposals::<T>::mutate(supersig_id, |active_proposals| *active_proposals += 1);
    1. Add an error variant for the case when there are too many active proposals:
    #[pallet::error]
    pub enum Error<T> {
        // ...
        TooManyActiveProposals,
    }
    1. Decrement the number of active proposals when a proposal is approved or rejected. You can do this in the approve and reject extrinsics:
    ActiveProposals::<T>::mutate(supersig_id, |active_proposals| *active_proposals = active_proposals.saturating_sub(1));

    As a non binding idea to test, we shall also be exploring the idea of enabling off-chain signing, though this will require a lot of refactoring:

    Enable off-chain signing (optional work)โ€‹

    To incorporate off-chain signing in the supersig pallet while maintaining the same features such as adding and removing members, we would need to do the following:

    1. Create a CallHash type alias to represent the hash of the call data:
    pub type CallHash<T> = <T as frame_system::Config>::Hash;
    1. Change the CallData storage item to use the CallHash instead of the actual call data:
    #[pallet::storage]
    #[pallet::getter(fn call_data)]
    pub type CallData<T: Config> = StorageMap<_, Twox64Concat, SupersigId, CallHash<T>, OptionQuery>;
    1. Modify the create and approve functions to accept a call_hash parameter instead of the call data:
    pub fn create(origin: OriginFor<T>, call_hash: CallHash<T>, ...);
    pub fn approve(origin: OriginFor<T>, call_hash: CallHash<T>, ...);
    1. In the create and approve functions, calculate the call hash and ensure it matches the provided call_hash parameter:
    // In the `create` function
    let actual_call_hash = T::Hashing::hash_of(&call_data);
    ensure!(
        actual_call_hash == call_hash,
        Error::<T>::InvalidCallHash
    );
    // as well add the check in the `approve` function.
    1. Add a new error variant for mismatched call hashes:
    #[pallet::error]
    pub enum Error<T> {
        // ...
        /// The provided call hash does not match the actual call hash.
        InvalidCallHash,
        // ...
    }
    1. Update the extrinsics and RPCs to work with call hashes instead of call data.

    Overviewโ€‹

    DOT serves three distinct purposes in Polkadot: governance, staking and bonding. These critical functions have increased DOT's demand but also segregated DOT's liquidity across multiple applications.

    Several parachains and protocols arise to enhance DOT's capital efficiency, which includes:

    • Staked DOT, e.g. Acala's LDOT and Parallel's xDOT
    • Crowdloan DOT, e.g. Acala's LCDOT and Moonbeam's stDOT

    These DOT derivatives, which represents different forms of DOT across the Polkadot network, further spread out DOT's liquidity. DOT's liquidity fragementation has caused several crucial issues:

    • Each DOT derivative need to bootstrap their own liquidity and find a stable pricing
    • Polkadot application builders need to support multiple forms of DOT assets

    These hurdles are extremely difficult to overcome, given Polkadot network liquidity is still relatively low. tDOT aims at solving these issues by generating unified DOT liquidity across Polkadot applications.

    Project Detailsโ€‹

    tDOT is a DOT-pegged derivative built on top of the stable asset protocol.

    Stable asset is based on Curve's stable swap algorithm and is back by a pool of assets with the same peg. It utilizes traders to dynamically rebalance pool composition while maintaining a consistent pool value, thus generating a synthetic asset whose peg is much stronger than any of the underlying assets.

    taiKSM is the first KSM-pegged derivative deployed on the Dotsama ecosystem. It aggregates liquidity from KSM and Acala's LKSM to generate unified KSM liquidity in Karura.

    image

    tDOT extends the idea of taiKSM to provide unified DOT liquidity over the whole Polkadot network. Its architecture is shown above:

    • For each xDOT, a separate xDOT-DOT stable swap pool is created on the parachain where xDOT is native;
    • Each xDOT-DOT pool can mint and burn tDOT on parachain A which is tDOT's hosting chain;
    • If xDOT is not on parachain A, e.g. cDOT and dDOT, xDOT-DOT pool uses XCM to mint and burn tDOT.

    Each xDOT-DOT pool is a trading pair between xDOT and DOT. It allows a dynamic trading range between xDOT and DOT but ensures the value of pool derivative is pegged to DOT. Each xDOT represents a different form of 1 DOT in Polkadot network. According to the stable asset algorithm, when the exchange rate between xDOT and DOT trades at 1:1, tDOT is 100% collateralized and is backed by exactly 1 DOT. When the exchange rate shifts, tDOT is over-collateralized and the collateral ratio increases as the exchange rate shifts further. Each xDOT-DOT pool can control how fast the collateral ratio increases with its own parameter values.

    Since each xDOT-DOT pool can maintain pegging of its own pool derivative, it's a natural choice to unify these pool derivatives into a single tDOT. This brings extra benefits:

    • It ensures a single tDOT and it can be bridged to any parachain;
    • It unifies all xDOTs over the Polkadot network. New xDOT assets can be included by deploying new xDOT-DOT pool on their native chains;
    • It provides sufficient application scenarios for each xDOT. Other than the xDOT-DOT swap, it allows xDOT holders to mint and use tDOT in DeFi applications;
    • It can be used as cross-chain swap medium. Assume that bDOT is native in parachain B and cDOT is native in parachain C. Users can mint tDOT with bDOT and then redeem tDOT to cDOT. This user effectively swaps bDOT on parachain B to cDOT in parachain C.

    Ecosystem Fitโ€‹

    tDOT will be minted on a single parachain which is the hosting parachain for tDOT. It can be migrated to a different parachain or even a dedicated parachain. The hosting parachain can deploy its own xDOT-DOT pools so that tDOT is minted locally.

    Any other parachains such as Acala and Parallel which have their own native DOT derivatives can deploy xDOT-DOT pools on their own chains and mint tDOT on the hosting chain as remote minters. Their benefits include:

    • The xDOT-DOT pool provides a stable swap between xDOT and DOT;
    • The xDOT-DOT liquidity is locked in its original chain while minting tDOT so the parachains can retain its TVL;
    • The minted tDOT can be bridged to other chains other than the hosting parachain. For example, the minted tDOT can be bridged back to Parallel and be used as collateral of Parallel's lending applicaiton.

    For the whole Polkadot network, a standardized DOT derivative can service the entire Polkadot ecosystem; it can unify all forms of DOT liquidity and unleash maximum usability for DOT across Parachains.

    Milestone 1 โ€” Stable Asset XCM Palletโ€‹

    • Estimated duration: 1 week
    • FTE: 2
    • Costs: 4,000 DAI

    Stable Asset XCM pallet is a new module which will be deployed in the host chain only. It manages balances and limits for each individual stable asset pools and acts as the portal to mint and redeem tDOT.

    Stable asset LPs will be divided into two layers:

    • Local LP, which is the LP of individual stable asset pools and managed by stable asset pallet;
    • Aggregate LP, which is the LP generated by local LPs and managed by stable asset XCM pallet.

    Project Overview ๐Ÿ“„โ€‹

    During this time, I have had the opportunity to work with several companies that wanted to adopt blockchain technology. However, I have observed that they often face challenges that hinder their adoption, mainly due to the following reasons:

    • Difficulties integrating legacy software with blockchain, such as dealing with long confirmation times or scalability issues when handling a large number of transactions. I have personally spoken with clients who need to handle over a million transactions per year, with peaks of thousands of requests per minute.

    • Concerns regarding wallet security, custody, accounting management, and the purchase of tokens for transaction fees.

    • Challenges in querying the blockchain to retrieve or interpret transactions over time, lacking a user-friendly interface.

    • High cost of using the blockchain (those who are not familiar with the blockchain world have heard of ethereum and how much it costs to do operations on it)

    There is a significant market potential for smart contracts, such as tracking the lifecycle of a product or certifying the immutability of sensitive files, among other use cases. While these challenges may seem trivial, integrating existing and well-tested software with experimental projects like blockchains (this is the common thinking of web2 companies) often leads to insurmountable issues, resulting in project abandonment.

    Our project offers an intuitive and user-friendly tool to simplify blockchain integration for all businesses.

    We are aware of the interest expressed by various companies in using blockchain technology, and we want to demonstrate how easy and advantageous it is to integrate blockchain into their business processes.

    We aim to convey that adopting blockchain is no longer a complex and costly process but can be accomplished effortlessly with our intuitive tool, leveraging the scalability capabilities of Polkadot and its Parachains.

    Our ultimate goal is to help companies embrace the benefits offered by blockchain, opening the doors to a new way of doing business. We firmly believe that our project can be a turning point for widespread adoption of blockchain in the corporate sector, simplifying the integration process and providing a seamless and positive experience.

    We have already scheduled several demos with our clients, including one that has requested a demonstration of how to support a high number of transactions launched within a short timeframe and how to effectively manage them.

    The client's request highlights the importance of efficient transaction management in a high-volume blockchain environment.

    Furthermore, we will illustrate our transaction management strategies that enable fair and optimized resource allocation, avoiding overload issues and ensuring a continuous flow of operations.

    Overviewโ€‹

    To address these challenges, I have decided to create a web application specifically designed for companies and users who are eager to venture into the world of blockchain. The application aims to bridge the gap between "Web2" and "Web3" by providing a simple API call to feed data into smart contracts, with an immediate response providing a unique identifier.

    To achieve this, I am developing a microservices architecture capable of handling millions of requests and scaling to accommodate peak traffic. Over the years, I have gained significant experience in building such systems, including a web application that processed tens of thousands of daily orders (including data-heavy files like photos for immediate printing) and effectively scaled during peak periods (e.g., the holiday season).

    My plan involves creating an endpoint that can be accessed from Web2, exclusively responsible for collecting data values to be inserted into a smart contract. Currently, I am focusing on storing key-value pairs; however, I intend to dynamically handle more complex cases in the future. In this way, the Web2 user will be relieved of any concerns regarding the bottleneck presented by the blockchain, as their task will already be completed (which we address through our bridge development), we can manage an unlimited number of requests per second, ensuring a smooth user experience. Upon successful transaction completion, we will send a registration notification to the customer, including all relevant onchain transaction data. Additionally, we will provide a graphical tool enabling users to verify their transactions onchain, ensuring transparency and data correctness.

    The application will handle all the necessary infrastructure setup for transaction transmission, including endpoint creation, failed transaction recovery, private key security, among others. The customer's role will be to select the appropriate smart contract type and chain for deployment, based on their future needs. For instance, in the future, certain data inputs may generate NFTs representing the final products, which could be utilized in other contexts through interoperability. Please note that this initial idea will not be present in the alpha version. Furthermore, we can leverage interoperability to store data in backup smart contracts created on secondary blockchains in case the primary chain faces congestion or other issues.

    Project Detailsโ€‹

    The project will consist of 9 microservices, each with a well-defined task.

    TrackingChainSchema

    StepTracking

    1. Triage API:

      • Purpose: Receives tracking requests, consults the registry, and associates a destination smart contract with each request based on a Profile.
      • Scalability: Can scale by increasing endpoints during high load periods due to no concurrency access issues.

    2. Aggregator Pool Worker:

      • Purpose: Moves tracking requests from Triage to the Pool after pre-filtering.
      • Scalability: Cannot scale due to concurrent access management but can handle large workloads efficiently.

    3. Tx Generator Worker:

      • Purpose: Sends transactions on-chain for tracked items in the Pool.
      • Behavior: Doesn't wait for transaction responses, only saves the returned Hash.

    4. Tx Watcher Worker:

      • Purpose: Monitors tracked items in the Pool with associated transactions for finalization.
      • Outcome: Inserts successful transactions into the transaction Registry; performs recovery actions for failed transactions.

    5. Frontend Admin:

      • Purpose: Manages the creation of associated accounts.

    6. Frontend Monitor:

      • Purpose: Monitors and manages tracking statuses in various states.

    7. Frontend Registry:

      • Purpose: Provides a user-friendly visualization of all tracked codes with direct links for on-chain verification.

    8. Web Application:

      • Purpose: Give the possibility to enter or view the status of onchain traced codes. (it will be fundamental for the demo that will have to lead us users to use the blockchain).

    9. Tx Monitor Worker:

      • Purpose: Monitor the status of transactions to proceed with any automatic actions or to launch alerts in the event of transactions that cannot be managed automatically.

    Overview of the technology stack to be usedโ€‹

    We are planning on using a combination of blockchain technology, cloud services, and front-end development tools to build a performant, secure, and user-friendly platform.

    Blockchain Layer:

    • Smart Contracts: Ink! and Solidity version for store the tracking values.

    Backend Layer:

    Frontend Layer:

    • Asp.Net MVC: These libraries will be used for interacting with the API from our frontend application.

    Ecosystem Fitโ€‹

    I plan to develop a WASM version, integrating the SubstrateGaming https://github.com/SubstrateGaming library developed by Ajuna and EVM smart contracts (C# will be utilized with the Nethereum library https://nethereum.com/ for interaction with compatible EVM networks).

    To ensure user authenticity, all smart contracts and wallets created on various chains will integrate with Kilt, associating a digital identity with each user utilizing the smart contract to certify data ownership.

    1.API: TriageWritten in Asp.Net, The Triage API acts as the gateway between the "Web2" world, which receives the Tracking requests, and the "Web3" world, where these requests will be saved. To do this it will verify that the incoming request is compatible with one of the profiles associated in the configuration, if so it will save the request in the Triage (and return an Guid to client) which will then be processed by the next service. In case the incoming request does not match any profile, it will be rejected. The Triage operation does not involve any concurrent processing, allowing for seamless scalability. It can accept requests simultaneously or even create multiple endpoints. The API expects a POST call with the following data: field Code used as a Key in the smart contract, field valueData used as one of the elements of the Value and the field Category that will be used to associate a profile with Tracking
    2.Aggregator Pool WorkerWritten in C#,The Aggregator Pool Worker will used to transfer processable data from Triage that has no time dependencies into the Pool. A transaction is transferable when there is no pending Transaction with same Profile to be completed in the pool
    3.Tx Generator WorkerWritten in C#,The Tx Generator Worker Worker will used to take data from Pool and make a transaction on onchain via smartcontract. In this case each worker instance takes one of the transactions entered into the pool and will process it by calling the selected smartcontract (this selection of smartcontract has already been made by Triage). Once the transaction has been made, it will save the HASH of the Tx so that it can be used by the next service. This service supports both (Ink! and EVM) TrackingChain smart contracts. The selection of the version of the smart contract to use will be given by the profile that was associated in the Triage phase
    4.Tx Watcher WorkerWritten in C#,The Tx Generator Worker Worker will used to check all Tx pending for finalized (or failed) status. Each worker instance takes a pending transaction and through the hash it will verify if it has been finalized successfully. This service supports both (Ink! and EVM) TrackingChain smart contracts. The selection of the version of the smart contract to use will be given by the profile that was associated in the Triage phase
    5.API: RegistryWritten in C#,Provide API for check the status of each Tracking request. Wich Guid of tracking request is possibile to watch the status of transaction. For example, the API will tell if the Tracking is in Trigae/Pool/Pending/Complete status and will provide all the times with which it moved from one status to another, as well as the onchain transaction information (gas used, hash tx. ..)
    6.Web ApplicationWritten in Asp.Net MVC pages for manage the insert tracking and views. A web interface from which it will be possible through a simple form to select the fields required to make a request towards the triage.
    7.Ink! Smart contracts.We will deliver a set of Ink! smart contracts that will able to track the key values. In particular, it will take care of saving in a dictionary key-value formed by a "Key" byte32 and the "Value" a list of bytes. A get call will also be available, which given a "Key" byte32 returns the entire "Value" list of Bytes saved over time, also providing the block number in which the transaction was carried out. It will also include the C# function that the "Tx Generator Worker" service will have to do to write onchain and the read call that will be used by the "Tx Watcher Worker" service. The implementation will partially reuse the C# SubstrateGaming library
    8.EVM Smart contractsWe will deliver a set of EVM smart contracts that will able to track the key values. In particular, it will take care of saving in a dictionary key-value formed by a "Key" byte32 and the "Value" a list of bytes. A get call will also be available, which given a "Key" byte32 returns the entire "Value" list of Bytes saved over time, also providing the block number in which the transaction was carried out. It will also include the C# function that the "Tx Generator Worker" service will have to do to write onchain and the read call that will be used by the "Tx Watcher Worker" service. The implementation will partially reuse the C# Nethereum library

    To activate an instantiated tribe, all listed founders must accept the terms, and conditions of said tribe, as defined in the initial create_tribe event.

    In the above diagram, after all the founders accept the creation of the tribe, the tribe is set to an active state. Once the tribe is active, it can participate in content leasing events.

    Alternatively, as depicted in the diagram above, if any founder rejects the create_tribe event, the tribe **will not be activated,** and is marked as closed.

    In order to continue, a new tribe must be created from scratch, and once again be approved by each founder.

    Lease Content

    Content leasing is how we expect to enable individual content ownership and distribution. Leasing expects 2 actors: the content creator (lessor) and the tribe (lessee).

    lease_content contract creates the on-chain representation between the specified tribe and the user-owned content by creating a cryptographic key that unlocks the original cryptographic content key which is used to decrypt that specific userโ€™s content.

    This model allows content to be encrypted with a single key-pair, that is stored using the userโ€™s own key-pair. A lease will decrypt the original content key, and create a new cryptographic key which can also unlock the original contentโ€™s key. Any key that is able to unlock the original content key will be derived from the original.

    Technology Stackโ€‹

    The tribal smart contracts will be written in ink!, which is native rustlang. The CLI, and other core components will use reputable libraries like clap to construct the actual CLI, and tokio to provide asynchronous task execution from within our libraries.

    All cryptographic functions will be derived from stock substrate libraries, and pallets.

    Most lower-level blockchain related functionality will also initially use stock substrate pallets like BABE and/or GRANDPA.

    At this time, any UX functionality will be mostly custom, with the exception of base substrate modules that can be loaded via WASM. We expect to have some client-side services to communicate with back-end services in real time via REST calls, and web sockets to communicate with multiple back-ends simultaneously. We expect all of this communication to be contained within what we are calling the Orchestrator, which will negotiate backend data, and transaction signing/submission with user approval. Because of the nature of itโ€™s utilities, we have determined that this workload should exist client-side exclusively.

    Proof-of-Concept (prior work)โ€‹

    Anย initial implementation of Tribal Protocol was written in C# from scratch without forking another chain to work out some of our system design questions. While we were able to get past rudimentary P2P networking and proof-of-stake consensus issues, the enormity of the task ahead caused us to re-evaluate. In the course of re-evaluating we determined that a language like C#, while powerful in its own right, was not suited to developing a L1 blockchain. This led us to Rust, and eventually to Substrate.

    Once we settled on the proper tooling, we were able to think more clearly about the problem domain, and how to go about implementing it. We discovered that we had to have smart contracts at the heart of our system if we wanted it to have the utility desired while remaining open to decentralization.

    After deep diving in ink! we realized that Substrate mitigated many of our network level architecture concerns, and gave us a smart contracting framework to build from. We spent some time building out small projects in Rust (including these crates: 1,2) and basic ink contracts in order to get more familiar with Rust, ink!, and Substrate prior to this grant submission.

    Non-Goalsโ€‹

    Weโ€™ll take this chance to be very clear that the work associated with this grant is not intended to create a production ready network or a consumer quality user interface. This is a designed to be the first major milestone towards building out our Tribal Network. Think of it as the first real development epic after completing our research spike on Substrate, ink!, and Rust over the last few months. The outputs of this grant are limited to the key deliverables detailed above and the deliverables outlined in the milestones below.

    Ecosystem Fitโ€‹

    Tribal Protocol will be a social media protocol that enables anyone to create their own web3 native social media platform on top of it. There are plenty of others that are attempting to fulfill a similar vision of โ€œdecentralizing social mediaโ€:

    However we donโ€™t believe that any of these projects have found sufficient levers and ways of mixing crypto and social to unlock the user growth needed for meaningful consumer adoption.

    What makes Tribal Protocol unique is our full stack approach to serve a very specific customer - people who want to become founders, co-owners, and contributors to entirely new niche social networks that they control. The vast majority of the space today is attempting to enable the โ€œdecentralized twitter or facebookโ€ products while not actually enabling early stage social networks to form. Our most critical differentiator from all other attempts in this space is the creation of DAOs that are directly tied to niche social networks. The economic alignment that DAOs unlock combined with the content moat from user driven content leasing is the secret sauce that allow nascent social networks to form.

    We will be โ€œdog-foodingโ€ our own stack to build out multiple non-crypto user base focused social networks with the goal creating 10 tribes / tribal protocol based apps each with 5K Daily Active Users (solid base of 50K DAU across protocol). Once we reach this milestone we plan to productize our no-code platform for non-technical individuals to launch and manage their own social networks built on tribal protocol. This last step would amount to something like a Wix for social media app creation + day-to-day DAO management tooling that weโ€™ll either build out or integrate with existing products from the ecosystem.

    The open source tech stack weโ€™re developing will help move the substrate and Polkadot ecosystem forward in ink! smart contract development, practical applications of DAOs and their associated management tooling. Please reference our whitepaper for more depth on the use cases Tribal Protocol unlocks and insight into our go to market strategy.

    Chris, Alec, and Jason launched a startup called CloutCast in April of 2021 and were a part of the first DeSo Foundation Octane Fund backed projects. CloutCast is โ€œweb3โ€™s promoted post platformโ€ - and aims to re-imagine what sponsored posts look like in the emerging web3 social media space. This project was a full contact immersion into web3 and gave us a lot of our technical and personal exposure to the major ecosystems and players in decentralized social media today.

    Prior to CloutCast the three members of this team met and built products together for a Miami based corporate startup studio. At that time Chris was the lead software architect, Alec was head of Dev-Ops, and Jason was head of product - churning out scalable software products from ideation to scale for a now $10B public company.

    From our years of working at a startup studio and our experience building out products on top of current social media products and protocols - we realized that we could do a better job of building a full stack solution in this space rather than continuing to play within other protocolโ€™s limitations. Taking on the L1 Tribal Protocol allows us to have full technical design flexibility as well as being able to capture the upside if our vision succeeds.

    Development Roadmapย ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    **Milestone 1 โ€” Implement Local Development Chain + Create Tribes**โ€‹

    A Tribe is the key actor in the tribal protocol - it is the DAO entity that allows for co-ownership of social networks on the protocol. This milestone will allow for the operation of a local development chain, including the custom Tribal Substrate pallet. The key output of this milestone is the ability to create tribes via an ink smart contract. In this milestone we will implement the basic structure of the Tribe entity and validations around Tribe creation.

    Project Overview ๐Ÿ“„โ€‹

    Develop Substrate runtimes based on the UTXO model.

    Overviewโ€‹

    Tuxedo is a framework for developing Substrate runtimes based on the Unspent Transaction Output (UTXO) model. The letters utxo are contained in the word tuxedo, hence the name.

    In the broader blockchain space, there are essentially two models for creating state machines, or runtimes, as they are known in the Substrate ecosystem. Those two models are the Account System as seen in Ethereum, Polkadot, and others, and the UTXO System as seen in Bitcoin, Monero, Cardano, and others. Currently the defacto way to write Substrate runtimes is with FRAME, which is based on the account system, and any project wishing to build on the utxo system is left to write a runtime from scratch or find a home in another ecosystem. Tuxedo would be a couterpart to FRAME based on UTXOs rather than accounts.

    Tuxedo would make the UTXO model more visible and accessible in the Substrate ecosystem and begin to create a diversity of runtime frameworks in addition to FRAME, a trend that we hope will continue beyond Tuxedo itself.

    Project Detailsโ€‹

    The primary advantage of UTXOs is that they are highly parallelizable. This fits well in Polkadot's multichain ecosystem where parachains execute and communicate asynchronously, and will be an even bigger advantage if (hopefully when) DAG based chains become popular, a trend that is already kicked off with projects like Aleph Zero, and many others outside the Polkadot ecosystem, including Hedera Hashgraph, Nano, and Casper Labs.

    The UTXO data model is relatively well established by Bitcoin as well as research from IOHK in their Abstract Model and Extended UTXO Model. Our primary tasks would be to implement this in Rust and expose a standard API for chain developers to build on. This is analogous to the API exposed by FRAME System and the Pallets built on top.

    Our core data types follow similarly, to the IOHK research cited above. The primary differences are that we do not assume a native cryptocurrency and rely on Tuxedo Pieces (analogous to FRAME Pallets) to provide the validation logic, rather than the UTXOs themselves.

    /// A UTXO transaction specifies some inputs to be consumed, and some new outputs to be created.
    struct Transaction {
      /// The inputs refer to currently existing unspent outputs that will be consumed by this transaction
      inputs: BTreeSet<Input>,
      /// Similar to inputs, Peeks refer to currently existing utxos, but they will be read only, and not consumed
      peeks: BTreeSet<Input>,
      /// The new outputs to be created by this transaction.
      outputs: Vec<Output>,
    }

    /// A single output of a transaction which has an owner and some associated data
    struct Output {
      /// The address that owns this output. Based on either a public key or a Tuxedo Piece
      owner: Address,
      /// The data associated with this output. In the simplest case, this will be a token balance, but could be arbitrarily rich state.
      data: Vec<u8>,
    }

    /// A single input references the output to be consumed or peeked at and provides some witness data, possibly a signature.
    struct Input {
      /// A previously created output that will be consumed by the transaction containing this input.
      output: OutputId,
      /// A witness proving that the output can be consumed by this input. In many cases including that of a basic cryptocurrency, this will be a digital signature.
      redeemer: Vec<u8>,
    }

    The core of the API exposed developers who create Tuxedo Pieces, will roughly follow this trait. We expect this will have to get more specific as our development shows us what we haven;t yet considered.

    /// The API of a Tuxedo Piece
    trait TuxedoPiece {

      /// The type of data stored in Outputs associated with this Piece
      type Data;

      /// The validation function to determine whether a given input can be consumed.
      fn validate(transaction: Transaction, input: Input) -> bool;
    }

    This grant does not strive to create the entire rich ecosystem of Tuxedo pieces that we hope to eventually be developed on top of Tuxedo. Rather it strives to create the core of the Tuxedo system and a few of the most important and exemplary pieces. Specifically, we strive to develop the analogs to FRAME Executive, FRAME System, Pallet Balances, and Pallet Transaction Payment.

    Ecosystem Fitโ€‹

    Tuxedo is a framework for writing Substrate runtimes. Substrate is the toolkit for building virtually all parachain nodes as well as many standalone blockchains. As such, Tuxedo provides a richer set of options to runtime developers, and hopes to attract teams to the Substrate / Polkadot ecosystem who may have otherwise gone elsewhere.

    The primary users of Tuxedo will be parachain and runtime developers who will use Tuxedo directly to structure their runtimes. Of course, the user base will trickle downstream as well to users of those parachains that choose to build with Tuxedo. However, chain users will use Tuxedo only indirectly.

    There are no projects like this in the Substrate ecosystem, although they do exist in the broader blockchain space; Cardano being the most notable example.

    While it fulfills a similar role, Tuxedo is not intended to compete with FRAME, but rather to compliment it, by welcoming projects that fit naturally with the utxo model into the Substrate ecosystem, as FRAME does for projects that fit the accounts model.

    Team's experienceโ€‹

    Joshy entered the Substrate ecosystem in 2019 as part of the Substrate Developer Hub team. There he created and hosted the weekly Substrate Seminar, and contributed significantly to the Substrate Recipes. In 2020, he moved to the Moonbeam team where he was a core developer. While at Moonbeam, Joshy wrote the Nimbus consensus engine which is used in several production parachains, and helped pioneer the technique whereby EVM contracts can interact with native Substrate pallets. In 2022, Joshy began contributing to the Polkadot Blockchain Academy, teaching in both Cambridge and Buenos Aires.

    Andrew entered the Substrate ecosystem from a curiosity point of view back in June 2021. From there he learned blockchain and Substrate via documents and tinkering in his off time after work. In December 2021 received a fulltime job for a venture builder to build a parachain to eventually connect to Polkadot. Andrew graduated from the first Polkadot Blockchain Academy cohort in 2022 in Cambridge. After Cambridge Andrew moved on from the venture builder to dive into education in the Polkadot Ecosystem by instructing and developing course curriculum for the Polkadot Devcamp #2 online. For Andrew's current work he is contracting as an instructor at the Polkadot Blockchain Academy for Parity Technologies lecturing and creating educational content for Blockchain Fundamentals(Specifically lecturing on UTXO vs Accounts models), Substrate, and XCM modules. Also Andrew is doing Rust Core development work for the Integritee Parachain. Andrew shares a passion for allowing blockchain developers the ability to build upon the UTXO model in Substrate.

    Joshy and Andrew met in Cambridge in 2022 at the first Polkadot Blockchain Academy. There Andrew chose the Frameless UTXO Project cited above as his final project.

    Development Status ๐Ÿ“–โ€‹

    The team has done previous work on this topic:

    • Joshy maintained the Substrate UTXO Workshop code as part of the Substrate Developer Hub team, and has continued to maintain it out of personal interest even years after leaving that team.
    • Andrew ported this code to work without FRAME as part of the Polkadot Blockchain Academy.

    The development so far has focused specifically on the cryptocurrency use case, whereas this grant proposes to generalize the code to be a framework for broader runtime logic development.

    As teaching staff at the Polkadot Blockchain Academy in Buenos Aires, Joshy and Andrew found themselves, on two occasions, in conversations with other teaching staff in which it was noted that a diversity of runtime development frameworks would make the Substrate ecosystem stronger and attractive to a broader development base. This idea was supported by Kian Paimani and Shawn Tabrizi among others.

We will then dive into how to add the multisig piece to your runtime, and how to develop your own simple piece starting from the piece template.
    1.Piece TemplateWe will create the template Tuxedo Piece analogous to the FRAME pallet template. This will allow runtime developers to have a concrete starting place when building their own utxo based Substrate runtimes.

    Future Plansโ€‹

    Being a framework for runtime development, we plan to continue developing the ecosystem of Tuxedo Pieces including Pieces for NFTs, Governance Mechanisms, Proof of Stake, and even smart contracts.

    Joshy has long had a vision of a UTXO based smart contract language based on the pi calculus. With Tuxedo core complete, it will be possible to develop such a contracting platform.

    The UTXO model allows concurrent processing of unrelated transactions (those that do not compete to consume any inputs). It would be exciting to extend Substrate itself to support a DAG structure rather than a linear chain to take advantage of this ability, although the feasibility of this extension has not yet been studied.

    Future Plansโ€‹

    Near Termโ€‹

    We have a vision for a Tuxedo parachain that acts as an Atomic Swap hub for DOT ecosystem assets to foreign UTXO chains like Monero, Zcash, Cardano, etc.

    The Farcaster provides a Monero Bitcoin atomic swap protocol. We intend to extend this protocol to support Tuxedo chains. And thanks to Polkadot's XCM, this would allow atomic swaps between other DOT ecosystem assets and foreign UTXO chains as well.

    Following completion of this grant, the path to working Atomic Swaps would be roughly

    1. Extend Farcaster to support swaps with Tuxedo.
    2. XCM integration with Tuxedo for Cross-chain UTXOS.
    3. Testing, auditing, etc.

    Medium Termโ€‹

    DISCLAIMERโ€‹

    This is grant proposal is very similar to one I had submitted previously. This was due to it being terminated, which you may view here.

    I have since severely changed the design of the protocol / project to provide a pallet-based architecture henceforth bringing more value. I realized the other proposal was not sustainable anyways (contract-based architecture), and this future-proofs and brings more value to the ecosystem as a whole.

    I hope mitigate any sort of conflict as interest as there was before. Please let me know if this is sufficient!

    Project Overviewโ€‹

    Overviewโ€‹

    The Uke Protocol is a p2p, completely distributed messaging protocol. It utilizes local cryptography and a Substrate blockchain instance to verify, send, and receive messages in real time - just like any other conventional messaging protocol, and can be used to construct messaging apps, or any other application in which real time messaging is needed.

    Substrate is a key part of this solution, as uke essentially defies the need for any sort of traditional backend in favor of a completely DLT based infrastructure.

    Initially, the PoC for this phase will be messaging app, however key components will be built that will allow for many more applications in the future. The eventual goal is a universal messaging protocol that can be implemented anywhere, and is not dependent on any one centralized backend.

    The purpose of this messaging app is to have it entirely independent of any third party service for both messaging and users - a true representation of web3.

    There is more to uke than just peer to peer messaging - itโ€™s to demonstrate a lot more can be created with DLT than just another cryptocurrency. Rather than exchange currency one another, uke aims to take those same concepts and apply them to data and messaging.

    I am passionate about bringing more value to web3 via this sort of application - something that can be used by people, but also in a wider context of businesses and confidential, secure messaging.

    Project Detailsโ€‹

    Project Expectations & Goals

    The initial goal for this grant is to allow for the development of a PoC of this messaging protocol in the form of a mobile app.

    In the future, as the protocol becomes more defined, the goal is to develop a suite of SDKs and docs centering around secure and confidential messaging for any use case - with Substrate and its extensive functionality being the core of the solution.

    Uke has a few primary goals and standards to upkeep:

    1. Privacy - each message sent is completely, and purely, peer to peer - no one else can intercept or decrypt the message.

    2. Fault Tolerance / Reliability - By using DLT, we remove the need for a central server, meaning as long as an amount of nodes are kept online, users can still talk to one another. This is especially useful in emergency scenarios, as users can even opt to run their own nodes to ensure 100% runtime.

    3. Anonymity - since each user is essentially just a cryptographic key paired with an id, userโ€™s can easily stay anonymous on and off chain if they so wish to choose.

    Technology Stack

    For the front end, Ionic will be used for all web, Android and iOS versions.

    The backend will purely be DLT based - for this one, a Substrate instance will be run to send messages back and forth between accounts. A custom pallet to interact and properly store messages in Substrate storage will be developed to do so.

    Below are the summarized languages / tech stack

    • Typescript / Javascript
    • Rust
    • Ionic

    High Level Architecture

    As a general overview, each message will be a signed extrinsic, and each user is essentially merely an account on the blockchain.

    Components

    For the purposes of defining the Uke PoC / MVP, the initial functionality of the uke pallet will only handle messaging and message storage. However, in the future, it is planned to implement further functionality, such as a more robust identity registrar and account filter system.

    1. UKE PALLET

    Using Substrate allows for the creation of a custom pallet, which will have two primary functions for this PoC:

    • Handle message transmission and conversation storage (via a few key StorageMaps for managing active and ongoing conversations).

    • Basic identity mapping (register() function to allow for a mapping of BoundedVec<u8> to AccountId for easy lookup).

    The messages will be stored and read from the Substrate storage via a common StorageMap for the time being. Functionality will be included to retrieve the conversation state without having to load all messages as well.

    In order to identity unique conversations, an ID (convo_id) is used to retrieval the correct conversation between two particular users. This id is generated by hashing the sender and recipient addresses to create a unique, yet deterministic way to identity conversations in storage.

    For identifying each user, a mapping for cryptographic addresses to more human readable names will also be created within the pallet. It essentially it maps unique, human readable ids to otherwise illegible addresses.

    With this mapping of addresses, users can then look up other users and add them to their contacts, or write them a new message, or any other package of data in theory.

    1. Substrate Instance

    The Substrate Instance will allow for all messages to be propagated, consensus to take place, as well as smart contracts to be deployed in a guaranteed environment as needed.

    1. Uke Messaging App

    The eventual conclusion, and primary deliverable of this proposal is representing all of the aforementioned technology into an easy to use, hybrid mobile app that will be released for use. This app can be used across either Kusama or custom Uke networks, whatever is deemed fit upon launch. The app will encrypt messages on the client side, where the encrypted text will be stored within the Substrate node.

    Mockups and Design of PoC App

    Keep in mind these are mockups, and are subject to change

    Ecosystem Fitโ€‹

    The eventual goal is to provide a streamlined way to for the following in the Substrate / Polkadot ecosystem:

    1. Provide a common, and easy to use identity solution
    2. Provide an out-of-the-box, flexible, and confidential messaging protocol which can be used for many different usecases.

    The target audience here is our own user-base eventually, but also developers through opensourcing all work done here along with documentation on how one can also setup their own messaging using our tools.

    Currently, there is no standard for how one can build a dapp quickly, and that does something common. This can serve as a baseline for how a dapp can function without the use of cryptocurrency or the like.

    What makes us different:

    1. No traditional backends are used here. Everything is purely based off of Substrate, as shown in the architecture diagram.

    2. In our designs, the use of DLT/blockchain is not shown - this is intentional, as it allows users to merely experience a secure messaging experience without the cumbersome interface.

He mainly has focused on creating front-end applications and architecture around purely DLT architectures for multiple companies. He is proficient in a number of programming languages and protocols, as well as general solution architecture for both low and higher level software.

    Some notable projects include:

    1. A PoC IoT device that logged sensor data directly to a blockchain. This included a custom UART serial protocol to convert Arduino code to blockchain transactions.

    2. Portable battery powered nodes, utilizing a Raspberry Pi. (I'd like to do this for Substrate as well!)

    3. The nftize project, an app that allowed for anyone to convert a physical asset to a digital one with ease.

    4. Implementing Shamir secret sharing for an "offline multi sig" and private key sharding model.

    5. A supply chain tracking system in which crop from the US was tracked to Japan over a private NEM blockchain instance.

    In his spare time, he also wrote many articles centered around using blockchain in practical and real world scenarios, which you may find here: https://iodlt.com/iodlt-blog/

    Project Overviewโ€‹

    Overviewโ€‹

    Uke is a p2p, completely distributed messaging protocol. It utilizes local cryptography and a Substrate blockchain instance to verify, send, and receive messages in real time - just like any other conventional messaging protocol, and can be used to construct messaging apps, or any other application in which real time messaging is needed.

    Substrate is a key part of this solution, as uke essentially defies the need for any sort of traditional backend in favor of a completely DLT based infrastructure.

    Initially, the PoC for this phase will be messaging app, however key components will be built that will allow for many more applications in the future. The eventual goal is a messaging protocol that can be implemented anywhere, and is not dependent on any one centralized backend.

    The purpose of this messaging app is to have it entirely independent of any third party service for both messaging and users - a true representation of web3.

    There is more to uke than just peer to peer messaging - itโ€™s to demonstrate a lot more can be created with DLT than just another cryptocurrency. Rather than exchange currency one another, uke aims to take those same concepts and apply them to data and messaging.

    Personally, I am passionate about bringing more value to web3 via this sort of application - something that can be used by people, but also in a wider context of businesses and confidential, secure messaging.

    Project Detailsโ€‹

    Project Expectations & Goals

    The initial goal for this grant is to allow for the development of a PoC of this messaging protocol in the form of a mobile app.

    In the future, as the protocol becomes more defined, the goal is to develop a suite of SDKs and docs centering around secure and confidential messaging for any use case - with Substrate and its extensive functionality being the core of the solution.

    Uke has a few primary goals and standards to upkeep:

    1. Privacy - each message sent is completely, and purely, peer to peer - no one else can intercept or decrypt the message.

    2. Fault Tolerance / Reliability - By using DLT, we remove the need for a central server, meaning as long as an amount of nodes are kept online, users can still talk to one another. This is especially useful in emergency scenarios, as users can even opt to run their own nodes to ensure 100% runtime.

    3. Anonymity - since each user is essentially just a cryptographic key paired with an id, userโ€™s can easily stay anonymous on and off chain if they so wish to choose.

    Technology Stack

    For the front end, Ionic will be used for all web, Android and iOS versions.

    The backend will purely be DLT based - for this one, a Substrate instance will be run to send messages back and forth between accounts.

    Below are the summarized languages / tech stack

    • Typescript / Javascript
    • Rust
    • Ionic
    • ink! (where applicable)

    High Level Architecture

    As a general overview, each message will be a transaction, and each user is essentially merely an account on the blockchain.

    Components

    For the purposes of defining the Uke PoC / MVP, the initial functionality of both modules will be represented via an ink! smart contract. However, in the future, it is planned to become a full pallet as needs become more apparent. If it is preferred for the initial implementation to be a pallet, then we can arrange that.

    1. Human DNS Module / Contract (future pallet)

    Using Substrate allows for the use of an ink! Smart contract, which in this case is used for mapping cryptographic addresses to more human readable names, just like a DNS. We call this the Human DNS, and essentially it maps unique, human readable ids to otherwise illegible addresses.

    With this mapping of addresses, users can then look up other users and add them to their contacts, or write them a new message, or any other package of data in theory.

    1. Account Rules Module / Contract (future pallet)

    Users can define rules for whether they wish to be contacted or not, and who can contact them. They essentially can create whitelists to explicitly allow who is permitted to message that specific account, along with what data can be sent in the future.

    This measure prevents a common issue with phone numbers, email, and even other apps - spam. Using smart contracts ensures the rules are kept in place, and the user is safe from any malicious or unwanted messages.

    Each message is a transaction on the blockchain, which depending on the rulings, can be deemed valid or invalid. In theory, one could set up their own Uke messaging network with very specific rulings in the future.

    1. Substrate Instance

    The Substrate Instance will allow for all messages to be propagated, as well as smart contracts to be deployed in a guaranteed environment.

    It's worth noting that I plan to implement the concept of light clients into each client-side instance, so as to provide

    1. Uke Messaging App

    The eventual conclusion, and primary deliverable of this proposal is representing all of the aforementioned technology into an easy to use, hybrid mobile app that will be released for use. This app can be used across either Kusama or custom Uke networks, whatever is deemed fit upon launch.

    Mockups and Design of PoC App

    Keep in mind these are mockups, and are subject to change

    Ecosystem Fitโ€‹

    The eventual goal is to provide a streamlined way to for the following in the Substrate / Polkadot ecosystem:

    1. Provide a common, and easy to use identity solution
    2. Provide a way to define account rules and filters in order to customize what transactions, messages, or accounts can interact with an account.
    3. Provide an out-of-the-box confidential messaging protocol which can be used for many different usecases.

    The target audience here is our own user-base eventually, but also developers through opensourcing all work done here along with documentation on how one can also setup their own messaging using our tools.

    Currently, there is no standard for how one can build a dapp quickly, and that does something common. This can serve as a baseline for how a dapp can function without the use of cryptocurrency or the like.

    What makes us different:

    1. No traditional backends are used here. Everything is purely based off of Substrate, as shown in the architecture diagram.

    2. In our designs, the use of DLT/blockchain is not shown - this is intentional, as it allows users to merely experience a secure messaging experience without the cumbersome interface

    Unified deployment for the collator node

    Project Overview ๐Ÿ“„โ€‹

    This application is the response to the Polkadot Collator Setup RFP

    Overviewโ€‹

    The main goal is to provide production-ready deployment for the Collator node that could work for any parachain with very few adjustments.

    There are a lot of parachains in the substrate ecosystem, and each of them has its guide on how to spin up a collator node astar, datahighway, moonbeam, hydradx, oak. Most of those guides are just examples of how to start a collator for testing purposes and are not production-ready. That complicates life for those who want to manage collators for several parachains because each new parachain requires an entirely new setup. We aim to pack a common part of infrastructure and Collator node deployment into functional building blocks that could be used with any parachain and make it highly extendable and configurable for each specific case.

    Every collator node has common steps to run it that do not depend on concrete parachain:

    • build
    • containerize
    • terraform infrastructure
    • deploy

    All of that could be automated and templated for all existing and parachains future. Even if building and containerization are relatively simple tasks, most teams handle them in their own way, sometimes far away from IaC best practices. Unfortunately, there is still no unified way approved \ recommended by Web3 so we aim to fill this gap.

    Project Detailsโ€‹

    First, we want to start from two unified Dockerfile templates for building and running collator node that suits best practices like minimal runtime, no root user, minimal port exposure, etc. Those templates could be easily extended with all required dependencies if needed.

    The next step is to provide reproducible and configurable infrastructure via terraforming one of the supported clouds. In most cases, Collator nodes have similar requirements on infrastructure, but in case of special requirements, it would be pretty easy to configure terraform scripts for the needs.

    Last step that requires most of the confgurability is a deployment step which would be handled by ansible scripts. We would provide unified deployment with configuration for the relay chain and common Collator parameters.

    Componentsโ€‹

    • Terraform deployment of the Collator infrastructure to the corresponding AWS and GCP clouds
    • Ansible scrips for the configurable deployment of a Collator node for different parachains

    Technologiesโ€‹

    • Docker as virtualization for the collator node
    • Terraform as IaC for the reliable and reproducible infrastructure deployment
    • Ansible as deployment automatization tool

    Ecosystem Fitโ€‹

    Currently, most parachains provide a setup guide on how to run the Collator on bare metal; however, it is neither automatized (hence non-reproducible) nor suits high availability standards. Our solution will provide most parachains with the out-of-the-box instrument for spinning up Collator. That would increase the reliability of the existing parachains as they may utilize reliability, high availability and scaling of Kubernetes. As well will significantly reduce the time and cost of spinning up the Collator for those who want to support several parachains

    This implementation consists of a Bluetooth Low Energy connectivity layer that manages the connectivity stack and all buffered I/O using native Android BLE frameworks. HypeLabs already maintains a production-grade implementation of such drivers, although those are deeply coupled with the Hype SDK, the companyโ€™s main product. For that reason, these drivers must be ported and isolated before being made available as a library dependency for other apps.

    One important aspect of this setup is the fact that, after connecting, the devices perform a handshake. This handshake constitutes a negotiation process between the two devices, with the intent of exchanging meta configurations and status information. The information includes whether the devices are connected to the Internet, for the purposes of role selection, and itโ€™s performed every time that this status changes. This handshake is performed in accordance with the Communication Protocol.

    Android Appโ€‹

    Figure 3. Mockup for the Android app. The screen on the left enables users to see their balance and to request transactions, while the screen on the right provides verified confirmation of a transaction request.

    The Android app enables users to manually request the implemented network functions. This app is simple in nature, since it is not the purpose of the project, but rather serves the purpose of testing and showcasing the networkโ€™s functions. Rather, other apps may implement the same functionality, simply by adding the implemented logic as a dependency, one that will be provided to the public in open source form and as a library dependency.

    The app is written in Java and built with Gradle, as is common for Android.

    Relay Serverโ€‹

    The Relay Server receives, decodes, and interprets requests from any Requester. This process of decoding and interpreting requests can be understood as the serverโ€™s Business Logic, according to the illustration in Figure 4. For example, the Relay Server must decide what Substrate API endpoints to call and in what order. As a result of that process, the server redirects the requests to the Substrate Network, and mediates the communications with the Requester. All cryptographic challenges are forwarded between the two as well, meaning that the Relay Server is not capable of faking transactions, although it does have visibility over the operations that occur.

    Figure 4. Architecture for the Relay Server, illustrating how a transaction request is relayed to the Substrate Network. Proxy devices query the Relay Server's API, which interprets the requests and propagates to the Substrate Network.

    The Relay Server is to be implemented as an AWS Lambda function that can be called publicly. Given that this server also integrates the Communication Protocol, it will be implemented in Java. It is also composed of a full fledged CI/CD pipeline, implying that updates to the deployment are easy to process. Given its implementation in Lambda, this server will be horizontally scalable, and capable of processing many millions of transactions per second.

    In future reviews, this logic should be optionally integrated directly into Substrate, with the intent of having Substrate and off-the-grid devices communicate end-to-end, without the need for mediators. However, due to the complexity of that endeavour, the Relay Server will replace that setup for an initial version.

    Validated Streams

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Validated Streams is a consensus primitive that aims to simplify the process of creating decentralized reactive oracles by providing a mechanism for verifying the authenticity and veracity of the data being used.

    In brief, we are providing a mechanism for proving the occurrence of events streamed from a custom application collocated with each of the validator nodes, facilitating developers of arbitrary off-chain applications in creating on-chain oracles sourced by those applications in a decentralized manner. To ensure the reliability and integrity of the data submitted on-chain, we require that at least two-thirds of the validators witness the event and confirm that it have indeed occurred off-chain.

    By implementing Validated Streams on top of Substrate, we hope it could integrate with Substrate-based smart contracts, allowing developers to build more powerful and sophisticated applications that take advantage of features from both Validated Streams and Smart Contracts.

    Validated Streams is a part of a grander vision of proactive blockchain applications that interact richly with the off-chain world while still remaining trustless and decentralized, that our team has been pushing for some years, and is now building piece-by-piece as we keep seeking the best ways to realize it.

    Project Detailsโ€‹

    Diagram of Validated Streams, with Stream service ingesting events from an application, passing them to a gossip, which then leads to on-chain transactions, that, after block finalization, get forwarded back to the application. (validated-streams.drawio.png)

    A Validated Streams oracle proves the occurrence of off-chain events, after they have been witnessed by at least 2/3-s of its validators.

    Each of validator is a Substrate node that has an attached trusted client. The client submits hashes representing events that have been witnessed locally. Since a malicious client could fabricate data or censor it instead of reporting to the validator, it is necessary that the operators of validators don't trust other validators (or thirdparties in general) with the task of witnessing events, but run their own trusted clients, perhaps even collocating them with the validator node.

    To avoid swamping or stalling the chain with blocks containing as-of-yet-invalid events (especially in cases where trusted clients have just started witnessing an event), after receiving an event hash, the validator first gossips that hash, signed, to other validators (using Substrate's sc_network_gossip API). The event hash is submitted as an extrinsic only once it has been witnessed by 2/3 of the validators (weighted by stake).

    Afterwards, the event is finalized through any of the usual on-chain mechanisms (such as GRANDPA), and once final, is considered proven by the Validated Streams oracle.

    As it is possible for momentary disruptions or malfeasance of validators or off-chain services sourcing the data for events to cause the state recorded on-chain and the state existing off-chain to differ, we send the finalized event hashes back to the trusted clients, which can then, depending on the exact use case, use this information to, e.g. adapt its own state to on-chain proceedings, witness some form of correction to the finalized events, or report the discrepancy to its users/operators.

    As noted on the diagram, we are planning to use a gRPC protocol for the communication of hashes between the trusted client and the validator node, instead of the more usual JSON-RPC used throughout Substrate, since such an API would allow the final product to be immediately usable with a wider variety of commonly-used programming languages and software development frameworks, and we aim to make the final product as accessible as we can.

    Do note that because the trusted client only ever submits hashes, a separate product (say, IFPS) would be required for it to retrieve the actual event contents.

    We have implemented a proof-of-concept implementation of Validated Streams as we've explored the Substrate API.

    While the Validated Streams concept is generic enough to apply to some existing oracles and maybe even blockchains, we want to encapsulate it in a way that other developers could then use to implement their own blockchain solutions on top. As such, within the scope of this project we will not be creating a new blockchain/consensus network, but only a software package implementing the Validated Streams protocol on top of Substrate, plus the related documentation, tutorials, suggested deployment configurations, and the like. Developers would then be free to take that package and run their own chains validating the events they configure them to.

    In addition, we find it important to note that Validated Streams as currently envisioned would only work in chains where the total number/weight of validators is known, such as proof-of-stake or private/consortium chains; further research might be able to lift that limitation in the future, but this is again outside the scope of this grant proposal.

    Ecosystem Fitโ€‹

    Creating reliable oracles can be challenging, as making a protocol, ensuring the accuracy of the data being used, and finding the validators to run one are all hard problems. While the Validated Streams abstraction doesn't automatically solve all of those problems, it allows developers to re-focus on providing validators with accurate data without needing to worry about creating a whole new protocol.

    Once finished, Validated Streams could be used to create decentralized oracles that provide off-chain data to other parts of the Polkadot/Kusama ecosystem, such as blockchains or applications that connect to the network via Polkadot's interchain communication protocols, or just Substrate-based smart contracts in general. In that case, parachain and dApp developers would benefit from having another way to provide real-time data to smart contracts or to build decentralized applications that interact with the real world.

    In addition, we see a use for Validated Streams in the creation of hybrid off-chain/on-chain applications, where developers use it to write traditional applications that are linked to a blockchain using a "validated" output "stream" of events. This can enable traditional application developers (such as ourselves, outside the Cooperative) to build applications that are more secure and trustworthy, as they can rely on the validation provided by the Validated Streams service.

    And, finally, we see some potential use cases around sourcing data for decentralized AI models (where Validated Streams would allow for a single consensus dataset to be built and added to in real-time, without necessarily giving any centralized party a final vote on what's included), and the creation of decentralized news platforms (where parties contribute news stories or verify the accuracy of existing stories), but it is possible that both of those would require additional thought, research, and development before they can be realized.

    There are existing projects similar to Validated Streams, many of which we've taken inspiration from.

    A major one would be Chainlink. While both work on providing ways to create and use oracles, Chainlink is a standalone decentralized oracle network that integrates with a variety of blockchain platforms, while Validated Streams is a Substrate-based blockchain-building framework that can used by decentralized applications directly. Also, Chainlink uses a reputation-based system to ensure the reliability of the data being provided by its oracles, while Validated Streams uses a consensus mechanism based on concrete events being witnessed to ensure the accuracy of the data being used by oracles.

    While a Chainlink Feed pallet already exists within the Polkadot / Kusama network, we hope that by offering something more directly based on top of Substrate, we might provide a viable alternative for developers who don't necessarily want to use Chainlink itself.

    The current prototype of the Validated Streams code lives in the https://github.com/comrade-coop/validated-streams repository. It's an initial draft that we used to figure out what we want to achieve and if it's possible to use Substrate for it. Now that we have this proof of concept, we are ready to go for a full implementation.

    Development Roadmap ๐Ÿ”ฉโ€‹

    Overviewโ€‹

    • Total Estimated Duration: 3 months
    • Full-Time Equivalent (FTE): 1

    Milestone 1 โ€” Implementation of Validated Streams gossip using Substrate's GossipEngineโ€‹

    • Estimated duration: 1.5 month
    • FTE: 1
    • Costs: 5,000 USD

    While our initial prototype is roughly functional in terms of delivering witness signatures to other validators, it is currently doing that in a very hacked and insecure manner. For the first milestone, we are looking to change that to use Substrate's existing gossip, as well as clean up the code overall, while also getting some documentation and tests in order.

    Once this milestone is complete, we expect that Validated Streams would be able to deliver its main functionality of validating events, though it might not be the most robust yet to real-world network connectivity issues (and perhaps even to some kinds of malicious interference).

    3.Substrate module: Stream serviceThe Stream service module will allow applications to connect to the validator node as a "trusted client", witnessing events observed in the off-chain world and receiving receipts of completed events.

    Milestone 2 โ€” Implementation of block deferral for blocks that contain unvalidated eventsโ€‹

    • Estimated Duration: 1.5 month
    • FTE: 1
    • Costs: 5,000 USD

    After refactoring our codebase and reworking the gossip protocol used, we would like to work on improving the behavior of the project in real-life conditions, by implement deferral for blocks that arrive before they have been fully witnessed and making any necessary adjustments after testing and benchmarking the code in live settings.

    Once this milestone is complete, we would consider the Validated Streams project functionally ready for incorporation in other projects.

    3..NET client sampleWe will deliver a .NET/C# sample application implementing an example trusted client that can be used by developers as a starting point for their own work.

    Future Plansโ€‹

    Our team is interested in utilizing the Validated Streams project as a key component in the development of Apocryph, a novel (and, we hope, revolutionary) blockchain platform designed to support proactive smart contracts, or "agents", that are capable of autonomously communicating with each other and taking action without the express need for human(/centralized) input. There, the Validated Streams project would allow agents on a future Apocryph platform to react to real-world events as those occur.

    In fact, we are currently exploring the possibility of building (and refining) our vision for Apocryph in a piecemeal fashion where we build each of the components that might be useful in other projects independently, before eventually combining them.

    In the shorter term, we will strive to maintain the repository, bugfixing and perhaps even new features, after the grant is complete, especially if there is interest in the project from outside parties.

    Additional Information โž•โ€‹

    How did you hear about the Grants Program? We found the grants program via GitHub Trending, while simultaneously discovering that Substrate would be a great fit for our project on accident. As that seemed like too good of a coincidence to pass up, we decided to apply.

    While our coop organization has received a previous grant from Aragon Nest for an unrelated project, this is the first grant we are applying to in regards to the Validated Streams project.

    We have worked on the code and vision for Apocryph for a few years now, ever since we noticed that many of our Cooperative's projects were facing very similar issues around moving data and organizing code--and deciding we could do better.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Decentralized Finance (DeFi) is taking off at a very rapid pace, and smart contracts running on the Polkadot ecosystem are starting to entirely revolutionize the landscape of modern commerce. However, as with any technological revolution, this transformation ushers new security challenges that must be tackled head on: Because financial transactions are automatically executed by DeFi apps, bugs and security vulnerabilities in these programs can โ€”and currently doโ€” lead to significant amounts of financial loss. For example, over the past year alone, there have been repeated occurrences of so-called โ€œflash loan attacksโ€, which exploit contract logic to manipulate the price of valuable assets, such as tokens, to obtain a purchase price well below its actual market value. In fact, according to many estimates, over 1.3 Billion dollars worth of funds have been stolen in the year 2021 alone, all because of some underlying software vulnerability. If such numbers are not staggering enough, add to this the fact that smart contracts are immutable once deployed: this means that there is no way to fix the vulnerability post-deployment even after the problem has been discovered.

    This is exactly why it is so crucial to ensure that the smart contracts on the Polkadot ecosystem are free of security vulnerabilities and that they function as intended before they are deployed on a distributed ledger. Here, at Veridise, our mission is to ensure the correctness of modern DeFi applications through state-of-the-art technology based on cutting edge formal verification research.

    Because many DeFi apps suffer from a common set of vulnerabilities (e.g., arithmetic overflows, flash loan vulnerabilities, transaction order dependence etc), a key component of the Veridise toolchain is a static analyzer, called Vanguard, for detecting such common vulnerabilities in ink! contracts. Because Vanguard is based on a technique called abstract interpretation, it is guaranteed to report a vulnerability if one exists (among the vulnerability types checked by Vanguard).

    Project Detailsโ€‹

    Vanguard is a static smart contract analysis framework written in C++. It runs a suite of vulnerability detectors, prints visual information about contract details, and provides an API to easily write custom analyses. Vanguard enables developers to find vulnerabilities, enhance their code comprehension, and quickly prototype custom analyses. The Veridise team has been designing the product vision of the Vanguard for quite some time. We will go over the project details and provide references below for more in-depth context.

    Static Analysis via Abstract Interpretation. At a high level, most static analyzers are based on a paradigm known as โ€œabstract interpretationโ€. Just as a regular interpreter for a programming language executes the program on some specific input, an abstract interpreter symbolically executes the program over sets of inputs.

    To make this discussion more concrete, consider a simple function F that takes an integer x and returns x2 (letโ€™s assume unbounded integers for the purposes of this discussion). A regular interpreter can tell us that F will return 2 when executed on 1 and that it will return 4 when executed on 2 etc. However, when we do abstract interpretation, we can ask questions about what F returns on entire sets* of inputs. For example, an abstract interpreter can tell us that F will return a value in the range [2, 10] when x is in the range [1, 5] or that the return value of F is always an even integer for any input x.

    So, how can an abstract interpreter do that? The key idea is to define the semantics of the programming language over some underlying abstract domain, where each element in the domain represents a set of inputs. Again, the best way to understand this concept is to contrast it against a standard interpreter for a programming language. We can think of an interpreter as a program that takes as input a mapping M from variables to concrete values and a code snippet S and produces a new mapping Mโ€™ from variables to values, as depicted below:

    drawing

    The idea behind an abstract interpreter is exactly the same except that it operates over abstract values, which are elements of an underlying so-called abstract domain. For instance, an abstract value could be an interval of the form [a, b] denoting a set of integers x such that a โ‰ค x โ‰ค b. Then, just a standard interpreter executes the program over a concrete input, an abstract interpreter executes the program over such abstract inputs:

    drawing

    So what does it mean to execute a statement over abstract values? Letโ€™s try to understand that through an example (again, assuming mathematical integers). Consider a statement like x = y+z, and suppose that our abstract values are intervals of the form [l, u]. If we know that y is in the range [a, b] and z is in the range [c, d], we can conclude that x is in the range [a+c, b+d]. This is precisely what we mean by abstractly (symbolically) executing a given statement! Now, how can we leverage abstract interpretation to detect smart contract vulnerabilities?

    Reentrancy Detection. One of the oldest DeFi attacks (responsible for the DAO Hack of 2016) is caused by โ€œreentrancyโ€, which occurs when a contract invokes a function of another contract before it finishes updating any necessary contract state (such as a contract variable tracking refunds). Since the target contract can invoke functions in the source contract (hence the name โ€œreentrancyโ€), this will cause the vulnerable contract to use stale values. This, in turn, can allow an attacker to access resources that they donโ€™t have any claim to. Commonly, such an attack is used to withdraw more funds from a contract than they actually have, as illustrated below:

    drawing

    How to detect them: Such reentrancy vulnerabilities can be detected by statically checking that no storage variables are updated after an external function is called. In particular, the static analyzer needs to compute which function calls can be made at every program point and which variables are updated. Then, if there exist two program points L1 and L2 such that (1) L1 can execute before L2, (2) L1 can invoke an external function, and (3) L2 can write to a storage variable, then there is a possible vulnerability in the code. It is worth noting that reentrancy vulnerabilities cannot be checked in a sound way using syntactic pattern matching โ€” e.g., storage variables may be updated in subtle ways due to pointer aliasing and external functions may be called in non-obvious ways (e.g., through other function calls).

    Ecosystem Fitโ€‹

    It is well-known that bugs in blockchain ecosystem can have catastrophic consequences. As it stands today, the security landscape within the Polkadot ecosystem is not as mature as other ecosystems such as Ethereum. This is due to insufficient security tooling infrastructure in the ecosystem. Currently, the Polkadot ecosystem does not have the static analysis, symbolic execution, and other security tooling products as other major blockchains. By building the static analysis tooling products for ink! contracts, the Polkadot security landscape is hardened by utilizing the expertise from the Veridise team.

    The target audience of the Vanguard analyzer are web3 developers who require a tool to ensure the robustness and security of their applications. Using the technical capabilities that Veridise provides, our project will meet the needs of the Polkadot community to harden their own ink! contracts away from commmon vulnerabilities such as DoS, ToD, Reentrancy, flashloan attack, and many others.

    To the best of our knowledge, there is no comprehensive security tooling product for ink! contracts. The best option that the developers have is to leverage Linting rules that are supported by ink! 3.0. It is well-known that linting rules can only handle local and shallow patterns and they are completely insufficient for expressing common but serious vulnerabilities such as flashloan and reentrancy attacks. The only similar one is the Slither tool for Solidity. However, Vanguard differs from the Slither project in multiple ways. First, Slither can only support Solidity. On the other hand, Vanguard is language-agnostic and can easily support different versions of ink! language. Second, according to the results from our recent research paper, by evaluating both tools on the entire smart contracts from Etherscan, Vanguard significantly outperforms Slither in terms of both false positives and false negatives.

    The Verida network stores personal data for end users. Every piece of data is signed by the originator of the data. For a patient record, a hospital visit may be signed by the doctor. For an insurance policy claim, a police incident may be signed by a police officer.

    Verida has developed a way to securely use this off-chain signed data as an input to smart contracts in a gas efficient manner. This capability unlocks a huge range of new use cases for smart contracts that can be leveraged by Polkadot applications.

    Expanding the Data Ecosystemโ€‹

    We are also developing an API Connector framework, trust framework and data schemas to enhance trust and enable growth in the Verida network. Once the Polkadot integration is complete, these capabilities can be unlocked for the broader Polkadot ecosystem.

    Supporting additional Polkadot Parachainsโ€‹

    Building on the foundational work completed as part of this grant proposal, Verida will be able to build support for additional parachains in the Verida Vault based on Chain Agnostic Improvement Proposal (CAIP) standards. Further examples and tutorials will be developed to support and enable developers.

    More details on our future plans can be found in the Verida Whitepaper.

    Avoiding Rust Deadlocks via Visualizing Lifetime

    • Team Name: Song's research group at Pennsylvania State University
    • Payment Address: TBD
    • Level: 3

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Rust is a new programming language designed to provide both safety guarantees that are like high-level languages and performance guarantees that are like low-level languages. To achieve this design purpose, Rust leverages static compiler checks to rule out severe memory and thread safety issues at the compilation time. At runtime, Rust behaves like C/C++ and could deliver performance that is as good as C/C++. Due to its safety and performance benefits, Rust has seen increasing adoption in building low-level systems software, such as OSs and browsers. Rust is also used to implement many software systems in the Web3 technology stack (e.g., substrate, polkadot, ink!).

    Rust's compiler checks are based on a suite of ownership and lifetime rules. The basic rule allows one value to only have one owner variable, and the value is dropped (freed) when its owner variable ends its lifetime. Rust extends the basic rule to allow ownership to be moved and borrowed, while still guaranteeing all accesses to a value to be within its owner variable's lifetime scope. Besides safety checks, lifetime is also used for automated resource management. For example, there is no explicit Unlock() in Rust. A Lock() function call returns a reference to the protected variable, and when the reference ends its lifetime, Rust automatically releases the acquired lock (by implicitly calling Unlock()).

    Rust's lifetime rules are complex and different from all other existing languages. It is challenging for Rust programmers to infer where a variable's lifetime ends. As a result, it is not uncommon for programmers to incorrectly identify the location where an implicit unlock is called. When a lock is held longer than programmers' expectation, the same lock may be acquired again or a different lock may be acquired before releasing the acquired lock, leading to a double-lock error or a lock-in-conflicting-orders error.

    In our previous work [1], we conducted an empirical study on real-world Rust concurrency bugs. We inspected GitHub commit logs for five Rust applications and five Rust libraries to collect previously fixed concurrency bugs. In total, we found 37 deadlocks due to the misunderstanding of where the implicit Unlock() is called, including 30 double locks and seven locks acquired in conflicting orders. These deadlocks constitute almost all lock-related concurrency bugs (37/38) in our collection. They are all from popular Rust software systems (e.g., Servo, Parity-Ethereum, TiKV, Redox) and have severely hurt the reliability of those systems before they were fixed.

    A brief description of the project.We propose to build an IDE tool for visualizing the lifetime scope of a user-selected Rust variable. We believe our tool can help Rust programmers avoid deadlocks at the development stage. After writing a piece of code involving a mutex, a programmer can select the return value of a locking operation or the locking operation itself (when the return is not saved to a variable). Our tool will visualize the lifetime scope of the return value (i.e., the critical section). The programmer can then inspect whether the end of the critical section is expected. In addition, our tool will conduct deadlock detection for the selected critical section and provide detailed debugging information for identified bugs, such as highlighting blocking operations or function calls leading to blocking operations.How our tool will be integrated into Substrate/Polkadot?Both Substrate and Polkadot are implemented in Rust. Previously, double locks or locks in conflicting orders were fixed in Substrate [2, 3]. After applying our prototype, we identified four previously unknown double locks in Substrate or the dependent libraries of Substrate/Polkadot. We reported detected bugs. All of them were confirmed and fixed by developers [4, 5, 6]. We believe our tool will effectively prevent Substrate/Polkadot programmers from making similar mistakes and other types of mistakes our tool will reveal.Why are we interested in creating this project?We are interested in building the tool due to three reasons. First, our previous empirical study shows that deadlocks due to the misunderstanding of Rust's lifetime rules are common in Rust programs. Visualizing lifetime can avoid these bugs during the development stage, benefiting the whole Rust community. Second, the misunderstanding of Rust's lifetime rules can also cause memory bugs such as use-after-free and double free. Thus, the proposed tool has the potential to combat memory bugs. Third, the experience of building the proposed tool can inspire similar tools for other programming languages featuring lifetime (e.g., Kotlin).

    What have we already done?We have built a prototype of the proposed tool. Our prototype can visualize a selected variable and conduct double-lock detection. We published a demonstration paper at CCS'2020 to describe the prototype. The paper can be found here: https://songlh.github.io/paper/vr.pdf. We also recorded a video to explain the prototype, and the video can be found here: https://youtu.be/L5F_XCOrJTQ.

    We applied the double-lock detection component to Substrate, Polkadot, and ink!. We found four previously unknown deadlocks. One is in Substrate. The other three are in the dependent libraries of Substrate or Polkadot. We reported all the detected bugs. All of them were fixed by developers based on our reporting. The information of the detected bugs is listed as follows:

    What are we going to do?We propose to extend the prototype along four directions:

    First, we will integrate our existing implementation of lifetime computation and deadlock detection to rust-analyzer, so that our proposed technique can easily cooperate with different text editors.

    Second, we will detect more types of deadlock bugs. Specifically, we will add the detection of locks with conflicting orders and misuse of mutex and non-mutex synchronization primitives (e.g., channel, conditional variable).

    Third, we will identify and visualize more blocking operations that can potentially lead to deadlocks in a selected critical section such as receiving from a channel and waiting on a conditional variable.

    Fourth, we will implement the visualization functionality by parsing the analysis results generated by rust-analyzer in a text editor (i.e., VS Code) and document our tool.

Our previous empirical study showed that there are also memory bugs due to misunderstanding Rust's lifetime rules, such as use-after-free bugs and double-free bugs. The proposed tool has the potential to help Rust programmers avoid these bugs. Of course, we need to explore what program elements should be visualized for memory bugs.

    Second, we plan to conduct a survey to understand what challenges programmers face when understanding Rust's lifetime rules and whether the proposed tool can really help them avoid deadlocks. The survey results will guide us on improving the proposed tool, and broadly speaking, the evolution of Rust.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    When building our app (The Wunderbar Network team is part of the Substrate Builders Program), we have used a very useful existing community template - the Substrate Front End Template from the Substrate Developer Hub. This template is built using React.js and JavaScript. We are proposing to create an alternative version of this template, which would achieve three major outcomes:

    1) Create an extendable template app, where developers can quickly connect and interface with the Substrate blockchain, using simple, clear and strongly typed examples, with a great baseline UX (which could provide a starting point for an entire new project).

    This will build on top of what the current community template provides.

    2) It would use Vue.js instead of React.js

    According to StackOverflow's 2022 Developer Survey, React.js is still undeniably in the lead when it comes to web framework popularity (according to the survey, 42.62% of projects would be using React), however at 18.86% Vue.js is still in the top 6 and is on the rise.

    3) It would be written using TypeScript as opposed to JavaScript.

    Even though most developers who code in TypeScript can work well with JavaScript and vice versa, the "conversion" is not always straight-forward, and despite JavaScript being around for a very long time (and seemingly not going anywhere), TypeScript is gaining rapidly in popularity and most greenfield projects would prefer TypeScript over JavaScript.

    According to same survey mentioned above, JavaScript is the most commonly used technology (for the tenth year in a row!), however TypeScript is steadily closing in. Looking at the loved vs. dreaded category though, the picture is very different - TypeScript is loved by 73.46% of developers (and is near the very top of the list), whereas JavaScript achieved a score of 61.46% to be placed in the middle of the table.

    Overall, we believe that the combination of TypeScript's strong, static typing, and Vue's simplicity will together serve the purpose of providing an alternative source of very clear examples of how to interface with a Substrate Node from a modern front-end application, which should be of great value to the community.

    Project Detailsโ€‹

    The core technology stack is Vue 3 + Typescript, integrated with the Polkadot.js set of packages. The app will deliver Vue3 native components and "composables" (reusable functions), that other developers will easily be able to integrate/build on top of.

    The app will also provide a Dockerfile and container.

    We have created a mockup design (in both dark and light mode), screenshots below (we also have a high-fidelity Figma file that can be provided upon request).

    Dark version Light version

    Note that Wunderbar Network team is already using the same technology stack to consume Substrate blockchain features into the app we are building as part of the Substrate Builders Program, therefore we already have experience in both the core technology stack, and the Polkadot.js API packages.

    This grant will not include future ongoing maintenance of the deliverables, unless agreed prior (i.e. smaller grants to periodically refresh/keep up to date), or additional feature requests after the agreed milestone deliveries. We will however address reported bugs and major security vulnerabilities.

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

    This app provides a more robust and extendable example/template app compared to the current Substrate Front End Template app, which should be of great value to builders within the ecosystem, that are utilising the same or similar tech stack as ours.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

    Primarily UI developers, although any builders interfacing with Substrate would find value. New users, hackathon teams, etc - would also be strong contenders to use this app as a template/baseline for what they are building.

    • What need(s) does your project meet?

    The combination of TypeScript's strong, static typing, and Vue's simplicity will together serve the purpose of providing an alternative source of very clear examples of how to interface with a Substrate Node from a modern front-end application, which should be of great value to the community.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

    The Substrate Front End Template from the Substrate Developer Hub. Our project aims to provide a more robust example app, providing all the benefits and advantages mentioned above.

    Overviewโ€‹

    Tagline: NFT infrastructure for Polkadot

    Goal: Offer the easiest and fastest way for developers to use NFTs on Polkadot via holistic open source (Apache 2) infrastructure and dev tooling.

    Project idea: This project will make NFTs on Polkadot available to developers and businesses across industries and around the globe. We will do so by building an open source NFT layer for Polkadot (and its Parachains). Technically speaking, we will extend our existing NFT infrastructure with an โ€œintegrationโ€ for the Polkadot ecosystem.

    Benefits for Polkadot:

    1. Dev Tooling: Developers will get new and powerful open source dev tools which will enable them to build new types of d/apps and services using NFTs on Polkadot. (This will be useful for d/apps from DeFi to marketplaces.)
    2. Traction: All our users/customers (public and private sector) will automatically be able to utilize the Polkadot ecosystem. In other words, we will funnel developers and business clients to the Polkadot ecosystem by making it accessible via our open source NFT infrastructure.
    3. Bridges to the โ€œold worldโ€: The project includes a component that enables backwards compatibility with todayโ€™s (web2) enterprise infrastructure like identity and access management tools (C/IAM; e.g. KeyCloak).
    4. Fueling adoption (Marketing): Walt.id is a top tier VC-backed startup that plans on fast growth (7-digits round, closure in Q4 2022/Q1 2023). Polkadot will strongly benefit from our marketing activities by participating at ecosystem events as well as our commercial enterprise activities. Our motivation: We are building an identity and NFT abstraction layer for enterprises. Consequently, we are adding support for more and more blockchains / web3 ecosystems and Polkadot is one of the most relevant web3 ecosystems.

    Project Detailsโ€‹

    Tech Stack: We will be using the following tech stack:

    • Walt.id solutions
      • Wallet Kit (incl. progessive web app, auth/exchange protocols like โ€œSign in with Ethereumโ€ or โ€œSelf-Issued OpenID Connectโ€, โ€ฆ)
      • NFT Kit (incl. OPA integration)
      • IDP Kit (incl. OpenID Connect integration)

    Mock Ups/Designs: Please find some mock ups from our Cloud Platform here: https://drive.google.com/drive/folders/1zHGYcpRvjmWo9QXy9W24np80M10nugeH (Note: While the project will be open source under the Apache 2 license, weโ€™re currently building a managed service/SaaS that will re-use our open source libs to further facilitate use by developers.)

    Architecture: Please find a first high-level architecture of the planned project: https://drive.google.com/file/d/1-PYK6DbuTAOPx6covHkk224rvf7bJChV/view

    Relevant prior work: Our identity, NFT and wallet infrastructure solutions are already used by thousands of developers, governments, DAOs and enterprises across industries. Moreover, we already built / are building a number of similar projects for other web3 ecosystems like Etheruem, Polygon, IOTA, OCEAN, EBSI, Gaia-X, Velocity Network as well and other major web3 ecosystems which we cannot yet name.

    Scope: The project will be focused on building three infrastructure products, which will extend our current open source libraries:

    • Wallet Kit: Implementation of a wallet infrastructure that enables developers to extend their apps with the ability to view, manage and utilize NFTs.
    • NFT Kit: Implementation of an NFT infrastructure that enables the verification of NFTs (e.g. ownership, meta data) and against customizable verification policies. Our NFT solution will support the ERC721 ink-based implementation and the two pallet-based implementations (Uniques and RMRK).
    • IDP Kit: Implementation of an โ€œIDPโ€ (Identity Provider) that enables NFT-based authentication and access management for web2 apps.

    The following limitations follow from this scope:

    • The project is focused on enabling NFT โ€œutilityโ€ use cases (i.e. verification of NFT ownership and metadata) in a verticale agnostic way (as described above). However, in the future we foresee projects around minting of NFTs.
    • The deliverables are open source libraries, which are built for developers. We will not ship elaborate user interfaces or applications for consumers.

    Ecosystem Fitโ€‹

    Users: Developers

    Needs: NFTs are becoming a core technology to enable digital ownership of assets. At the end of the day, we believe that every asset will be tokenized and NFTs are a way of doing this. As a result, we see a growing need for solutions that make it easy for developers and businesses to build products with NFTs - in particular we see a need to realize the utility functions of NFTs such as in the context of access management. Recent projects by global brands like Starbucks (โ€œOdysseyโ€) reveal that the market is hungry for new applications of NFT that go beyond the simple tokenization of things.

    Value: We create value for

    • Developers
    • Businesses
    • Parachains / ecosystems based on Polkadot
    • Polkadot

    Similar Projects: There are no comparable projects according to our contact person at the web3 foundation. However, there is a number of organizations who are building Parachains and solutions in the NFT space like unique, RMRK, KodaDot, Enjin.

    USP: Enterprise-grade, open source NFT infrastructure layer for developers building on Polkadot.

    • Estimated duration: 2 - 4 months, with final deliverys in Feb 2023.
    • FTE: 6
    • Costs: 29.750 USD (Total costs: 35.000 - 15% good will discount)
    NumberDeliverableSpecification
    0a.LicenseApache 2.0
    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes and send test transactions, which will show how the new functionality works.
    0c.Testing and Testing GuideCore functions will be fully covered by unit tests to ensure functionality and robustness. In the guide, we will describe how to run these tests.
    0d.DockerWe will provide a Dockerfile(s) that can be used to test all the functionality delivered with this milestone.
    0e.ArticleWe will publish an article or workshop that explains what was done/achieved as part of the grant.
    1.Architecture / DocumentationWe will plan and provide the architecture of the proposed project. (Note that the architecture may be updated / extended throughout the project based on learnings from the actual implementation.)
    2.Wallet KitImplementation of a wallet infrastructure that enables developers to easily integrate NFTs from the Polkadot ecosystem in any app (e.g. web3, banking, consumer products, marketplaces, โ€ฆ). In other words: Developers will be able to extend their existing apps with the ability to view, manage and utilize NFTs (e.g. for trading or access management). The Wallet Kit is developed in Kotlin and comes with a Docker container incl. REST API.
    3.NFT KitImplementation of an NFT infrastructure that enables developers to build holistic applications and end-to-end use cases based on Polkadot. In this first proposal we focus on enabling โ€œutilityโ€ use cases (e.g. ticketing, loyalty, vouchers, access). Therefore, the NFT Kit will enable the verification of NFTs across multiple dimensions (e.g. ownership, meta data) and against customizable verification policies (based on the Open Policy Agent). Our NFT solution will support the ERC721 ink-based implementation and the two pallet-based implementations Uniques and RMRK. The NFT Kit is developed in Kotlin and comes with a Docker container incl. REST API. Note, that it relies on 3rd Party libraries/services that also need to be hosted.
    4.IDP KitImplementation of an โ€œIDPโ€ (Identity Provider) that enables NFT-based authentication and access management for web2 apps. Backwards compatibility is enabled by transforming NFT verification results into tokens (e.g. JWT) that can be handled by potentially any web2 app (e.g. identity/access tools, messengers, website builders, eCommerce frameworks, CRM tools). The Wallet Kit is developed in Kotlin and comes with a Docker container incl. REST API.

    Future Plansโ€‹

    Walt.id has been funded by one of Europeโ€™s top tier early stage investors / VCs and we are just about to close another funding round (7-digits round, closure in Q4 2022/Q1 2023), less than a year after our pre-seed. This will help us to further extend our product portfolio and at the same time unlock a substantial amount of marketing budget in order to promote the usage of our tools within our supported ecosystems (like Polkadot). Hence by investing and launching our own professional commercial activities targeting developers and enterprises who potentially benefit from our tools, we will fuel the growth of the Polkadot ecosystem substantially. This includes participating at events, conferences, and hackathons. Further, we are planning on building our own dev community events and activities, in order to promote cross-chain collaboration and knowledge sharing.

    Summing up, we have big plans for the Polkadot ecosystem and we believe that Walt.id can become an integral part of it. Thatโ€™s why this first grant proposal is just the beginning, and we envision to build a holistic identity, NFT, wallet and storage infrastructure layer for developers and innovators building on top of the Polkadot ecosystem. As such, the project is aligned with our long-term goal of building an abstraction layer for every web3 identity and NFT ecosystems.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Supporting WasmEdge as an alternative Substrate WebAssembly runtime. The project increases the Substrate ecosystem's node software diversity by supporting an alternative high-performance WebAssembly Runtime implementation. The project team are the maintainers of the WasmEdge WebAssembly Runtime project, and had successfully completed W3F projects in the past.

    Project Detailsโ€‹

    Software stack diversity (or โ€œdeveloper decentralizationโ€) is key to building a resilient blockchain network. As Ethereumโ€™s history has shown, the availability of multiple node software implementations, from GETH to Parity-Ethereum, has greatly improved network stability and security. When a critical bug is discovered or exploited on one implementation, the other would help sustain and stabilize the network.

    The Substrate framework and libraries are compiled into WebAssembly bytecode and run on a WebAssembly runtime in order to achieve safety and portability. It is therefore a low hanging fruit to support multiple alternative WebAssembly runtimes to improve software diversity at the foundation of the Substrate stack.

    Currently, Substrate runs on the Wasmtime WebAssembly runtime created by the Mozilla and Fastly team. WasmEdge is another leading WebAssembly runtime hosted by the Linux Foundation / Cloud Native Computing Foundation (CNCF). It is fully compliant to the WebAssembly specification as well as standard WebAssembly extensions. It is supported across many OSes including Linux, Windows, Mac OS X, seL4, and CPU architectures including x86, aarch64, and Apple M1. WasmEdge is among the fastest WebAssembly runtimes available today.

    Compared with Wasmtime, WasmEdge features a completely different software architecture. It is written in C++ and depends on the LLVM for runtime code generation, while Wasmtime is written in Rust and depends on Cranelift for dynamic compilation. That makes WasmEdge a compelling choice for improving Substrate software stack diversity.

    In this project, we propose to use WasmEdge as an alternative WebAssembly runtime for Substrate. We will create a software layer that allows users to choose between Wasmtime and WasmEdge when they build Substrate from source. We will also evaluate the performance characteristics of the two runtimes.

    Ecosystem Fitโ€‹

    The proposed project will bring an alternative runtime at the base of the Substrate stack and hence benefit the entire ecosystem.

    It could also bring Substrate developers communities closer to WasmEdgeโ€™s developer communities in cloud native (Linux Foundation / CNCF) and LLVM ecosystems.

    Web3 Compatible API for Substrate EVM Chains

    Project Description ๐Ÿ“„โ€‹

    Project Moonbeam (https://moonbeam.network/) aims to create a Polkadot parachain that offers Ethereum compatibility. We envision Moonbeam serving as an easy entry point to Polkadot for existing Ethereum developers -- a place where Ethereum based Dapps can run with a minimal amount of changes required. We believe this will help drive adoption of Polkadot by reducing friction for existing Ethereum based projects and by providing compatibility and support for the rich set of Ethereum ecosystem tools such as Truffle.

    Substrate already includes key components needed to achieve Ethereum compatibility, most notably the EVM frame pallet which is a full EVM implementation in Rust, and a basic way to dispatch calls to the EVM. However, there are other critical missing pieces needed to achieve Ethereum interoperability. One of these is a Web3 compatible API that offers the same API as an Ethereum node. Another is Pallet-Ethereum, a Substrate runtime that Parity is developing that extends and enhances the way calls are dispatched to the EVM that is contained in Pallet-EVM.

    We are seeking grant funding to help build a Substrate based Web3 compatible API that will interface with Pallet-Ethereum. We plan to use this implementation as part of Moonbeam, but other projects that want to implement Ethereum compatible parachains or parathreads could also include them into their projects and benefit from them.

    Overviewโ€‹

    The Crosschain NFT Pallet is a unique initiative designed to facilitate the smooth movement of NFTs across various blockchain networks, utilizing the XCM protocol. Through the implementation of this pallet, individuals can effortlessly exchange NFTs between relay chains and parachains.

    Project Detailsโ€‹

    xNFT

    The xNFT Pallet provides the following extrinsics (functions):โ€‹

    1. transferSingleNFT(admin,collection_id, item_id, dest_collection_id, dest_item_id, mint_to, dest) โ€”> DispatchResult ; transfer an NFT with the NFT ID
      • admin โ€” the owner of the NFT being sent.
      • collection_id โ€” the ID of the collection of which the nft is being sent.
      • item_id โ€” the ID of the NFT being sent.
      • dest_collection_id โ€” the ID of the collection to which the nft is being sent.
      • dest_item_id โ€” the ID of the NFT being created.
      • mint_to โ€” the new owner of the NFT being sent.
      • dest โ€” a multilocation to define the destination address for the tokens being sent via XCM. It supports different address formats, such as 20 or 32-byte addresses (Ethereum or Substrate).
    1. transferMultiNFT(admin,collection_id, item_id, dest_collection_id, dest_item_id, mint_to, dest) โ€”> DispatchResult ; transfer multiple non-fungible tokens, defined by their multilocation
      • admin โ€” the owner of the NFT's being sent.
      • collection_id โ€” the ID of the collection of which the nft is being sent.
      • item_id โ€” the ID's of the multiple NFT's being sent.
      • dest_collection_id โ€” the ID of the collection to which the nft is being sent.
      • dest_item_id โ€” the ID's of the multiple NFT's being created.
      • mint_to โ€” the new owner of the NFT's being sent.
      • dest โ€” a multilocation to define the destination address for the tokens being sent via XCM. It supports different address formats, such as 20 or 32-byte addresses (Ethereum or Substrate)

      • admin โ€” the owner of the collection.
      • collection_id โ€” the ID of the COLLECTION being sent.
      • dest โ€” a multilocation to define the destination address for the tokens being sent via XCM. It supports different address formats, such as 20 or 32-byte addresses (Ethereum or Substrate).
    2. transferCollectionOwnership(new_owner,collection_id, dest ) โ€”> DispatchResult ; transfer the collection ownership on another chain, defined by their multilocation
      • new_owner โ€” the new owner of the COLLECTION being sent.
      • collection_id โ€” the IDs of the COLLECTION being sent.
      • dest โ€” a multilocation to define the destination address for the tokens being sent via XCM. It supports different address formats, such as 20 or 32-byte addresses (Ethereum or Substrate).

    A feature will be added to the XCM VM for minting NFt on target chain using the encoded data from source chain.โ€‹

    This xNFT pallet will be tightly coupled with the NFT pallet in Substrateโ€‹

    Project does not include:โ€‹

    • This pallet does not let you create, mint or burn any NFT this just to send them to other chains by making use of the XCM functionality
    • This pallet will not be able to transfer any NFT that is not registered using the NFT pallet for Substrate(i.e NFT deployed as smart contracts).

    Ecosystem Fitโ€‹

    • The implementation of the xNFT pallet would introduce improved interoperability, expanded applications, increased liquidity, and enhanced flexibility to the Substrate ecosystem. It would foster the growth and vitality of the community, while facilitating seamless exchange and utilization of NFTs across different Substrate-based blockchains.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    • Tagline:

    Research ink! based domain service integrated with XCM

    • Brief Description:

    Our team secured first place in the ETHWarsaw hackathon in 2022 with AZERO.ID, an on-chain domain service using ink!, by winning the Aleph Zero Foundation's bounty. The team has since developed a sophisticated on-chain NFT domain platform in ink! v4, and is set to launch on the Aleph Zero mainnet. Our next objective is to expand the platform to the Dotsama ecosystem and leverage its full potential by enhancing it with the use of XCM. Moreover, we have already challenged the potential value creation for the Polkadot ecosystem with different people at Parity.

    • An indication of how your project relates to / integrates into Substrate / Polkadot / Kusama:

    AZERO.ID is the first sophisticated on-chain domain name service natively written in ink!. Because at Scio Labs, we envision a future where Substrate smart contracts are predominantly WASM-based. Our plans include launching the initial version of our protocol on the Aleph Zero mainnet as well as our new landing page and dApp soon. We plan to enhance our platform by utilizing XCM, to evolve into a unified Dotsama/Substrate domain name service. As the shift towards WASM-based smart contracts gains momentum, we believe the Dotsama ecosystem is ready for a native on-chain domain system that offers interoperability and usability across all Parachains.

    • An indication of why your team is interested in creating this project:

    We harbor a profound interest in the domain of on-chain identity with the belief in Substrate and ink! as the leading tech stack for the future of web3. Bringing our domain platform to Dotsama will not only demonstrate the capabilities of ink! and XCM, but add a lot of utility for users in the Dotsama ecosystem. Also, we love to craft great end-to-end user-facing applications well beyond just the infrastructure layer.

    A unified on-chain domain standard significantly improves the user experience of handling cross-parachain transactions. Further, on-chain NFT domains are the key primitive of a user's on-chain identity and can be integrated into any kind of application. Our domains provide additional utility via a flexible metadata storage field to store DIDs, verifiable credentials, and subdomains to enable organizational and enterprise use cases. Further, tradeable on-chain NFT domains are a tangible product that increases demand for Polkadot block space and improves ecosystem adoption, as previously seen on Ethereum and other chains.

    Project Detailsโ€‹

    • The problem(s) that you want to investigate, and why these are important:

    We aim to resolve the challenge of identifying the optimal technical architecture for a Dotsama-wide on-chain NFT domain service and how XCM can be leveraged to achieve this. Thus, before we can build an XCM-based domain service in ink!, we will need an in-depth understanding of the XCM technology, currently available standards, and their limitations. Once we have developed a deep understanding, we will identify all potential levels of integration, assess their feasibility, and finally propose the technical architecture of an XCM-based domain service.

    • Research questions/hypothesis:

    Find below a list of research questions we have identified. This list is not final; other questions might arise in the research process. 

    * To what extent is it possible to make XCM calls via ink! smart contracts at the moment, and what will improve in the foreseeable future?

    * Does XCM support calls between different smart contract languages? Like ink! <> Solidity.
        
    * What does a cross-chain domain service via XCM actually mean?

    * How can XCM be used to achieve "cross-parachain" domain-to-domain asset transfers?

    * How is the gas & registration/renewal fee payment handled? 

    * Is XCM needed for cross-chain domain โ†” address resolving?

    * Can domains be registered from every parachain via XCM? How can a unique namespace be maintained across parachains?

    * Can XCM be used to enable cross-chain NFT domain trading and transfers?

    * Are domain/NFT assets stored on a single chain only? Or, if they are stored on multiple chains how are they tracked on the other ones accordingly?

    * What ink! NFT standard can be used for the best compatibility across the XCM ecosystem? Should a new one be proposed?

    * Can XCM enable smart contracts to access the metadata storage field of our domains regardless of where the smart contract is deployed, and the NFT domain is stored?

    * What general security implications must be considered when building a cross-chain domain system with XCM?

    * What happens if a domain is updated on one chain while it is being used to transfer assets on another chain at the same time? What kind of other race conditions could occur?

    • Methodology that will be applied:

      • Acquire in-depth knowledge about XCM from all available resources.
      • Identify the design principles to consider while building an XCM-based dApp.
      • Evaluate different ways (like teleportation vs reservation) to accomplish a given task and identify its pros & cons.
      • Propose a plausible high-level architecture of a cross-chain domain service implemented in ink! and integrated with XCM.

    • Expected results and how they would be double-checked by the grants team (reproducibility of the data analysis):

      • The first milestone will yield a report on our analysis of XCM and list potential domain integration options without assessing their feasibility.
      • The second milestone that concludes the scope of this research project delivers a detailed assessment of the potential ways to integrate XCM and proposes a high-level architecture of a cross-chain DNS using XCM.

    • Intended venue for results publication and the timeline for publication:

      • The results will be published for public access in the form of a Litepaper, and a reference is submitted to the w3f/Grant-Milestone-Delivery. Additionally, we plan to communicate the results in a dedicated blog post & our social channels.

    • What your project is not or will not provide or implement

      • This project's scope does not include any form of the actual development of the proposed solutions in the final deliverable. The development of a PoC and, moreover, production-ready implementation could be subject to follow-on grants. Though, we'll provide a technical deliverable in the form of a public repository that showcases some sample cross-chain contract interactions with ink! & XCM (see Milestone 2).

    Ecosystem Fitโ€‹

    • Where and how does your project fit into the ecosystem?

      • Our project aims to become the standard for on-chain domains on Polkadot, Kusama, and any Substrate chain such as Aleph Zero. Our protocol and NFT domains are developed with ink! and therefore prepared for the future of WASM-based smart contracts on Substrate.

    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?

      • There are different target audiences for our NFT domains. First and foremost, our domains target any user on Substrate chains. On-chain domains are the first step in establishing an on-chain identity and improving the UX for on-chain interactions. Second, our project addresses all wallet providers as well as dApp/UI & parachain developers who are interested in implementing the user's on-chain domains.

    • What need(s) does your project meet?

      • Having a unified NFT domain standard on the smart contract level that works across all Substrate chains and is natively developed with ink!.
      • Improving the user experience for all Polkadot/Kusama and Substrate chain users
      • Attracting more users to Polkadot/Kusama and Substrate chains
      • Improving the security for Polkadot/Kusama/Substrate users by preventing address poisoning and other wallet address-related phishing attacks
      • Reducing the likelihood of losing funds by error-prone handling of wallet addresses while transferring assets
      • Demonstrating the capabilities of Substrate's user-facing application layer with great UX & Frontend.

    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?

      • Polkadot Name Service
      • ASTR Domains (Astar Domains Service)

    • If so, how is your project different?

      • We are developing the very first sophisticated NFT domain name service fully written in ink!. Moreover, we are focusing on creating a standard that works across the whole Polkadot/Kusama ecosystem by integrating XCM. Our NFT domains include some unique functionalities, such as a flexible metadata storage field that enables the attachment of any kind of metadata to the domain. Further, we deliberately focus on crafting great user-facing applications with unmatched UX in the space of decentralized domain name services.

As mentioned above, this could also mean deriving a new Polkadot Standards Proposal (PSP) from this.
    • We will be working together with Parachain-, wallet-, and dApp-teams to foster the adoption of our domains and create value and utility via integrations for the users.
    • We envision the project to translate into a fully community-owned DAO with on-chain governance. With social consensus, we will develop AZERO.ID and its upcoming XCM-enhanced counterpart to become core pillars for on-chain identity.

    Project Overview ๐Ÿ“„โ€‹

    XCM SDK is a tool that provides an interface to send XCM messages for Substrate based blockchains. This library is written in Typescript so it can be imported in a whole new set of applications or dApps that use Javascript/Typescript engines such as Node.

    The idea of this project is to have fast way to send XCM messages between the relay chain and the parachains without having to use Rust-written tools or other platforms/applications.

    This project is focused on the Polkadot ecosystem but it can be used in any other Substrate-based blockchain that uses the XCM pallet.

    Blockcoders is a team that is always contributing to blockchain projects to help the growth of the ecosystem.

    Ecosystem Fitโ€‹

    Help us locate your project in the Polkadot/Substrate/Kusama landscape and what problems it tries to solve by answering each of these questions:

    • Where and how does your project fit into the ecosystem?
      • It provides a solution for all those who are interested in sending xcm messages from a project in typescript. It is a key tool to integrate this messaging format in applications.
    • Who is your target audience (parachain/dapp/wallet/UI developers, designers, your own user base, some dapp's userbase, yourself)?
      • Mainly developers who are interested in creating applications/tools that need to send this type of messages since this sdk facilitates the integration of xcm messaging.
    • What need(s) does your project meet?
      • This sdk provides a fast and easy way to send xcm messages. Being written in typescript allows more developers to access this type of messaging without the need to use the polkadot.js browser or libraries that are written in Rust.
    • Are there any other projects similar to yours in the Substrate / Polkadot / Kusama ecosystem?
      • There are other tools for sending xcm messages but none like the one proposed here. The rest of the tools are Rust libraries, applications like polkadot.js.org among others. This SDK is focused on being able to access these features from projects written in Javascript/Typescript.

    Project Overview ๐Ÿ“„โ€‹

    We are creating a XCM Implementation for Fungible Assets - xtokens.

    Overviewโ€‹

    Polkadot Cross-Consensus Message Format (XCM) is a generic message format that is very flexible but loosly defined. Therefore, we need to provide an implementation of required use case e.g. cross-chain transfer, for parachains to be interoperable with the same context, namely send/receive fungible assets between parachains, and between relay chain and parachains. We have developed an implementation guide, as well as a reference implementation xtokens that has been used by Acala, Laminar, Plasm, and HydraDX successfully completing cross-chain fungible token transfers on Rococo parachain testnet. We are supporting many more projects including Moonbeam, Centrifuge, PolkaBTC, Darwinia, Kilt, Crust and Snowfork to implement this and enable our chains to be composable with each other.

    We believe all chains on Polkadot/Kusama shall be composable with each other, from exchanging values to exchanging and altering states. The cross-chain fungible asset implementation is the first step towards this goal.

    Project Detailsโ€‹

    We have already delivered the work we outlined in a PoC state, we will continue the development to meet the best practice outlined in the implementation guide at a production-grade standard, and this grant is applied partially in retrospect.

    Below are deliverables:

    • XCM Fungible Asset Implementation Guide that outlines fungible asset design considerations and discussions, serving as a draft best practice. (see here)
    • A reference implementation of cross-chain fungible assets - xtokens PoC (see xtokens here and xcm-support here)
    • A detailed documentation for other parachains to use these pallets, configure cross-chain assets, open HRMP channels on Rococo to test the cross-chain transfer etc. (see docs here)
    • Further develop xtokens to implement parachain and fungible asset identifier to handle asset conversion, assetId conversion, and multi-location conversion etc in a more generic and extensible way as described in the implementation guide
    • We will contribute the xtokens code to the orml (open-runtime-module-library) so anyone can use and further extend it.

    Ecosystem Fitโ€‹

    This is another common-good implementation that would be useful to any parachains who want to send and receive fungible assets from other parachains, as well as send/receive relay chain token between relay chain and parachain. We have tackled many XCM and HRMP caveats while implementing xtokens, which would save much time for many other projects and accelerate innovations on top of cross-chain value exchange. We also foresee this work will inspire more collaboration and discussion within the parachain ecosystem, and could also inspire similar development for non-fungible assets.

    We are not aware of other implementations at this stage, but hope to inspire more.

    The YibanChen will provide users a way to start using web3 internet daily. The Note-pallet will provide the ecosystem with a streamlined method to create, store and transfer communication data. YibanChen will also enable users to move from centralized website hosting to a decentralized web3 model with the Site-pallet. The Name-service-pallet will provide a mechanism for federated login with an substrate user owned wallet.

    The audience will be users that want to start using web3 for communication, website hosting and login. We also expect to support Substrate blockchain developers, which will want to reuse our pallets and connect to our infrastructure. In the future we'll integrate and support cross-chain messaging by leveraging XCMP.

    We are unaware of any of project that is focusing on critical components, such as email/communication, basic web3 hosting, and decentralized federated login, these services will enable a user to move from web2 to web3.

    We looked at the system.remark call, while we found system.remark would allow for simple note creation, but would limit the ability to enhance our Note feature. In the future we plan to add two gatekeeper mechanisms on the note receiver side. First, whitelist a set of wallet address senders, and secondly the ability of a wallet address to set an amount of token required to be sent along with the note before the wallet address would accept the note. We also have had some initial feedback that users would be interested in selling the notes, which we believe utilizing ORML-NFT would be the best for this scenario for selling notes in the future.

    0b.DocumentationWe will provide both inline documentation of the code and a basic tutorial that explains how a user can (for example) spin up one of our Substrate nodes. Once the node is up, it will be possible to send test transactions that will show how the new functionality works.
    0c.Testing GuideCore pallet functions will be fully covered by unit tests to ensure functionality and robustness. ReactUI testing will be covered by selenium tests. In the guide, we will describe how to run these tests.
    1.name-service-palletThis pallet will provide users the ability link a name to a wallet.
    2.Riot/Matrix botA Riot bot will be created that allows users to sign a data string with their Substrate based wallet. The bot will then place a judgement and verify the Riot user has control of the wallet.
    3.React Name ViewWithin the existing ReactUI the users will be able to set(), clear(), update() the name-service-pallet for their individual substrate wallet.
    4.React name-service-pallet authentication libraryA javascript library will be created which will provide helper methods to developers to enable easy integration with a React application and substrate chain running the name-service-pallet. This library will help enable federated login within existing React frontend by supporting Polkadot.js browser extension and YibanChen name-service-pallet.
    5.React Name authentication integration tutorialsA tutorial blog writeup and video will be created explaining to developers how they can use leverage verified accounts for federated login within their existing React frontend by supporting Polkadot.js browser extension and YibanChen name-service-pallet.
    6.Write testsTests will need to be written for each the pallet and the bot service.

    Future Plansโ€‹

    YibanChen plans operate on both the Kusama and Polkadot chains and will be the first application of it's kind that delivers decentralized communication, generalized name login service, and web3 website hosting, all built on Substrate.

    However, Development of the YibanChen won't end after all milestones are met. We plan to add features such as expanding Name Service feature to support more blockchain storage objects, such as other decentralized protocols and substrate chain discovery. We are looking at integrating with more decentralized storage protocols such as DatProtocol. Prototyping and testing additional user interfaces including more p2p driven interfaces such as removing IPFS gateways with a combination of IPFS.js and offchain::ipfs. Also supporting smolDot in the front-end for substrate communication. We also plan on building a community around Voting to help try and enable better forms of democracy and governance on and off chain.

    There are lot possibilities where this project YibanChen can go and we are very excited to get started on it and make a difference within the Web3 ecosystem.

    Additional Information โž•โ€‹

    Currently we have no funding for the YibanChen system, we feel getting the general web3 use-cases off the ground will kick-start the substrate ecosystem in a big way. We are excited to be part of the Substrate and Polkadot community and we will continue to contribute as much as we can. Thank you for your time and thank you for considering us for the Web3 Open Grant.

    Team Motivationโ€‹

    After launch, we sat down to listen to our users to understand what to build next.

    We were inspired by Superhuman onboarding experience and we thought that if an email client can onboard their users 1:1, crypto staking - which is like hundred times more complex process - should deserve a 1:1 onboarding.

    Therefore we onboarded like 20 users on Zoom and 50 users through chat and patiently listened to their feedback as well as smoothening out a bunch of nonobvious things in the flow.

    An example of a user onboarding session is here (shared with the permission of the user).



    After going through all user onboarding sessions and discussions with users on chat/telegram, we came to an understanding that in the path to increase adoption, the next critical constraint to solve is to onboard users to the best practises of how to go about staking.

    To gain a sense of the problem, the traction we have mentioned above is all through funds that were sitting inside Polkadot browser extension ๐Ÿ˜ฑ.

    We believe that stakers shoudn't need to trade off security over convenience when they can have both with YieldScan.

    In that line of thought, we want to help stakers onboard to best practises by:

    1. Developing a wizard that helps user understand the why behind setting up distinct stash and controller account --> and them helping them do so.
    2. Recommend moving large asset holdings to hardware wallets.
      • That means incorporating hardware wallet support into YieldScan
    3. Combining point 1 and 2, a user will be able to use Ledger + distinct controller account to stake onto Polkadot and Kusama.

    Zenlink DEX Smart Contract

    • Team Name: Zenlink
    • Payment Address: 3FyMZ4Y6wFXkaSzdBPetizppR5bD6BVLUy
    • Status: Terminated

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    Based on the prediction of the further growth of the DEX ecosystem in the future and the rapid development of the public blockchain technology, we propose a Polkadot network-based, high-liquidity, cross-chain DEX Network, Zenlink.

    It is a decentralized exchange network that consists of Zenlink DEX Module, Zenlink DEX Aggregator and other DEX Application on parachains.

    System Componentsโ€‹

    In general, Zenlink project consists of the following parts:

    • Zenlink DEX Protocol: The top-level unified general DEX protocol which can be implemented by the following ways. We prefer to make it to have Auto Market Maker(AMM) function and be easy imported into parachain in multiple ways.
      • Module: it's implemented as a Substrate pallet which can be imported into the runtime of a parachain.
      • Smart Contract: it's implemented as a smart contract which can be deployed into the ink! pallet of a parachain.
    • Zenlink DEX Aggregator: A simple and user-friendly entrance of DEX world which is able to connect with most of DEX on Polkadot, so that user can do one-click trade with multiple DEX on low slippage
    • Zenlink Token(ZLK): The native token of Zenlink DEX Protocol which can be used to distribute liquidity benefits and governance, etc

    Zenlink Ecosystem

    As a result of the above components, a decentralized exchange network, Zenlink DEX Network, will be established.

    Benefitโ€‹

    Parachains don't need to implement dex functionality by themselves since Zenlink DEX Protocol has two implementations so it is easy to be integrated. After that, the tokens of parachains would be involved into Zenlink DEX Network by trading with other tokens of other parachains. The more parachains integrate with the protocol, the more tokens users can exchange, so that they would be like to be a market maker and benefit from the value of the flow.

    Firstly, Zenlink DEX Module and Smart Contract will be implemented based on Zenlink DEX Protocol. In order to complete the Zenlink ecosystem, we would like to deploy it to a substrate blockchain and build a front-end website application, Zenlink DEX Dapp, for test.

    Secondly, we would like to build another important component, Zenlink DEX Aggregator. It will connect to Zenlink DEX Dapp.

    Thirdly, we will test the full function of Zenlink DEX Module and Aggregator on Kusama. Users also can try it on Zenlink DEX Dapp.

    Finally, the whole infrastructure(Zenlink DEX Module and Aggregator) will be deployed to Polkadot, so that Zenlink DEX Dapp will be switched to Polkadot network and published.

    Zenlink Architecture

    What we will implement in this grantโ€‹

    We will make the protocol has cross-chain dex functionalities in this grant.

    In the past grants(Zenlink DEX Pallet and Zenlink DEX Smart Contract), We have implemented Zenlink DEX Protocol in two ways and verified its basic dex functionalities, such as token issue, trading, deposit funds, etc. However, the tests are all based on a single Substrate chain. So that, we would like to move further to make cross-chain value liquidity be possible on Zenlink DEX Network. For now, the best testnet should be Rococo which supports parachains and be free. There are still lots of things to do.

    Firstly, we will spike some asset modules, for example orml-xtoken which is used for identifying assets in different parachains. Then, we will adapt Zenlink DEX Module to the asset module.

    Secondly, using the asset module and Zenlink DEX Module, we will implement an one-click cross-chain assets swap. The result is that user can send a swap transaction in Parachain200 which targe to the dex in Parachain300, then user will get another token in Parachain300.

    Cross-chain Assets Swap

    Finally, we will deploy the whole system to Rococo v1 to open test for everyone.

    In generally, the purpose of this grant is to deploy Zenlink Protocol to Rococo V1, then verify the cross-chain dex functionalities.

Zenlink DEX Smart contract is not obsolete since those two implementation could be used by different cases. If a parachain doesn't want to integrate with Zenlink DEX Module into its runtime, it also has another option -- deploying the Zenlink DEX Smart Contract into its smart contract pallet, like ink!.

    The purpose of this grant is to offer more options for parachain projects to introduce Zenlink in a friendly way.

We prefer to make it to have Auto Market Maker(AMM) function and be easy imported into parachain in multiple ways. If it works, there will be only a small effect to migrate those components to the better test network, such as Kusama and Rococo.

    For the tech architecture details, please see whitepaper/Zenlink DEX Protocol

    For the AMM initial design, please see whitepaper/Trading Paradigms - CFMM

    In a word, The Zenlink DEX Module will be integrated with a substrate blockchain. And all the components will be packed into a docker image. Once testers run the docker image, the substrate blockchain will be running. At the same time, the dex functionality will be active. So that testers can not only call the functions via RPC request, but also some script in terminal.

    The purpose of this grant is that verification function prototype in lean way.

    Project Overview ๐Ÿ“„โ€‹

    We would like to implement a parachain which specializes in privacy.

    This parachain supports confidential transfers and privacy preserving smart contracts on the mainchain based on the plonk. To support privacy, the traditional blockchains need to implement L2 solutions, complex contract logic or depend on centralized security assumption. The L2 technologies often sacrifice the usability, the complex contract logic cost too much gas and development workload, and the centralized security assumption force us to believe someone you have never met before. As the solution for these problems, we are going to implement parachain supporting privacy on mainchain and depending on only cryptographic hardness assumption. The documentation is here.

    Overviewโ€‹

    Through this grant, we would like to implement confidential transaction functionalities for both transfers and smart contract executions. There are two types of privacy confidential and anonymous. In this scope, we support the confidential transactions which hide the input and output. The anonymous hides the users related to the transaction. The anonymous is going to be supported in the future. We provide the confidential transactions for both transfer and contract execution.

    Project Detailsโ€‹

    This parachain privacy preserving protocol relys on the cryptographic hardness assumptions. There are some components consisting this system and We divide the components as following.

    • primitive: Basic cryptography libraries necessary for the network.

    • functionality: Confidential transactions pallets to realize the privacy.

    • module: Developer tools to develop the confidential smart contracts and output the constraints metadata.

    • client: Wallet libraries to transfer and execute the confidential smart contracts.

    We describe the detail as following.

    Primitiveโ€‹

    The primitive provides crypto libraries necessary for functionality as pallet.

    1. Lifted-ElGamal encryption pallet
    2. zk-SNARKs plonk pallet which supports the plookup and aggregation proof on top of ZK-Garage/plonk
    3. Encrypted balance pallet

    Functionalityโ€‹

    The functionality provides the confidential transfers and confidential smart contracts functions as pallet.

    1. Confidential Transfer pallet
    2. Condidential Smart Contract pallet

    Moduleโ€‹

    The module provides the developer with tools and necessary libraries managing privacy application.

    1. Encrypted ink!
    2. Contract constraint builder
    3. Proof generation library
    4. Confidential smart contract IDE

    Clientโ€‹

    The client provides the transactor client libraries for users.

    1. Key generation wallet
    2. Decrypt and encrypt transaction and balance
    3. Create zero knowledge proof of plonk
    4. Confidential transfers
    5. Confidential smart contracts executor

    Use Caseโ€‹

    We explain the use case we assume.

    diagram1

    Ecosystem Fitโ€‹

    This is the world's first account based and plonk built-in parachain which supports confidential transactions for both transfers and contract executions only depending on the cryptographic hardness assumptions. We can contribute to Polkadot network mainly in three ways.

      1. High performance and Polkadot friendly cryptography primitive

    Our team has been working on zk-SNARKs probjects for long time so we are sure that we can contribute to implement cryptography pallets confidential smart contracts, homomorphic encryption and so on which require a high degree of skill and these will be used for many developers. Most parts of them are composed by cutting edge technologies for example plonk which supports plookup and proof aggregation, and encryption library which supports somewhat homomorphic encryption so we can catch up them. Especially, we have been working on prover time optimization using speed up algorithm, assembly and parallelize, and also exprienced implementing plonk as pallet so we can design the fastest encryption primitive which is Polkadot friendly no_std and parity SCALE Codec compatible.

      1. Privacy preserving XCMP

    We are planning to connect this blockchain to Polkadot as parachain after redesign and optimization. We will be able to use these blockchain functionalities in the entire network. It means that all parachain in Polkadot network can use privacy preserving transactions. We think that this is huge benefit for Polkadot network users because they can easily use the confidential transactions whatever parachain they use.

      1. Research and development

    We would like to improve privacy and scaling using cryptographic scheme. We are going to do experiment about rollup transactions and block compression for storage scaling, Fully Homomorphic Encryption and MPC for privacy. Especially the Fully Homomorphic Encryption will be the next hot topic we are going to focus on.

    Similar Projectโ€‹

    There are some similar projects. We compare their features.

    Comparisonโ€‹

    diagram2

    The most valuable point is that we implement zero knowledge friendly blockchain. The main problem of confidential smart contract projects is the gas limit problem. The additive homomorphic encryption and zk-SNARKs are using heavy arithmetic workload and these processes often exceed the gas limit so it's important to design the blockchain as zero knowledge friendly structure. To make it practical, we think that the Substrate is suitable for three reasons. The account base blockchain, customizable Wasm and zero knowledge scheme.

    The prover side, the more simple structure we generate the zero knowledge proof, the more efficiency we get. The account base blockchain using the key value mapping so it's more efficient than UTXO. We can save the prover time with account based structure.

    The verifier side, we need to optimize the virtual machine performing the zero knowledge function to define case specific bytecode. We can customize the bytecode and get benefit from efficiency of Wasm VM.

    Considering both sides, the zero knowledge scheme is related deeply to calculation workload and the zk-SNARKs is the most efficient one but has a setup scheme. Previously, the zk-SNARKs setup parameters depended on circuit so we needed to setup parameters when we deployed some new contracts. It's hard to ensure that there are enough parties for each deploy contracts so almost contract base confidential smart contract project uses the bulletproof. However, we use the plonk which can generate the parameters without depending on circuit so once we setup the parameters, we can reuse that parameters for every transaction with getting profit of zk-SNARKs efficiency.

    Project Overview ๐Ÿ“„โ€‹

    We have been working on Zk projects and scalability solutions and now we would like to implement Zk plonk pallet.

    The plonk is called universal zkSNARK because of two reasons. The verification times are constant and original reference string can be used to build proofs with any type of circuit. These features bring significant benefits to both users and developers. For example, the verification time is the same so users don't have to wait so long even when they prove complicated proof, and original reference string can reuse so developers don't have to do trusted setup for each circuit. The plonk will be a core technology in terms of scaling and privacy so we should support.

    Overviewโ€‹

    Through this grant, we are going to make a plonk pallet in order for the developer to implement plonk on substrate easily. We are working on scalability solutions but currently, the substrate doesn't support zkSNARK pallet so we think it's a issue to fix. As aforementioned, zkSNARK will be a core technology in blockchain area and especially plonk is cutting edge technology so we are excited to implement this as pallet.

    Project Detailsโ€‹

    We'd like to implement the plonk library as a pallet in order for developers to customize circuits and use the plonk protocol.

    The following diagram is the libraries we are going to implement.

    • Polynomial commitment
    • Circuit builder
    • Generate proof and verify keys
    • Verify proof

    Ecosystem Fitโ€‹

    According to Web3 Foundation, there are at least 2 different teams that work on ZK technologies.

    Glacier is building a Distaff VM for zk-STARK proof generation and verification that are used to make private smart contracts and private credential verifications. The difference between us is that we are making a zkSNARK pallet and they are making a VM which supports STARKs. In terms of Zeropool, they are making private transactions contract pallet using bellman groth16 protocal and we are making zkSNARK libray using plonk.

    We believe zkSNARK with plonk will be core technology of next blockchain area. That allows Substrate to protect the privacy and scale on the huge number of transactions without decreasing the security level.

    ZK Rollup on Polkadot/Substrate

    • Proposer: NoCtrlZ, akru, and SotaWatanabe
    • Payment Address: 1DJTSPajRFCjdfn5UgPXGRo6Di8EE1Dzox

    Project Overview ๐Ÿ“„โ€‹

    We have been working on off-chain scalability solutions aka layer2 solutions. After tremendous research, we have come to believe that ZK Rollup would be the killer layer2 solution because of its data availability. Currently, rollup is one of the potentially interesing topics of Web3 Foundation and Vitalik announced the rollup centric Ethreum roadmap last month. According to Vitalik, the Ethereum ecosystem is likely to be all-in on rollup (plus some plasma and channels) as a scaling strategy for the near and mid-term future. We know that Polkdot has a different technical architecture and tech stack but Rollup is still important because of severtal reasons.

    1. Bringing vertical off-chain scalability without sacrificing on-chain data availability, security and privacy (ร—3-10 scalability).
    2. Handling smart contracts on layer2.
    3. Sharding plus Rollups will be the future. Polkadot has the sharding ish architecture but it doesn't have Rollups yet.
    4. Currenntly, a lot of Ethereum projects are interested in migrating from Ethreum to Polkadot. And some of the great Ethereum projects have already started using Rollups. If we could build Rollups on Substeate/Polkadot, we would help these projects migrate smoothly.

    Through this grant, we will make a ZK Rollup pallet for Parachain builders to get zero-knowledge vertical scalability.

    Overviewโ€‹

    Throught this grant, we are going to make a ZK Rollup pallet for potential Parachains like Plasm. Our initial goal is to implement ZK Rollup on Plasm but we aim to make it public and adoptable for all Substrate based chains.

    The following diagram is the architecture we will implement.

    Screen Shot 2020-11-10 at 23 03 01

    There are four components we implement as a substrate pallet and these components allow substrate-based chain to do following things.

    • Prover: Create proof which verifies the block validity.
    • Operator: Collect transactions, create a block and submit the block to mainchain contract.
    • User Wallet: Send transaction to operator and deposit token on the mainchain contract.
    • Mainchain Contract: Hold user's desposit, verify block and update state.

    Ecosystem Fitโ€‹

    According to Web3 Foundation, there are at least 2 different teams that work on ZK technologies.

    In our understanding, Glacier is building a Distaff VM for zk-STARK proof generation and verification that are used to make private smart contracts and private credential verifications. The difference between us is that we are making a ZK Rollup pallet and they are making a VM which supports STARKs. In terms of Zeropool, we couldn't find their info on Web3 Foundation's github.

    Project Overview ๐Ÿ“„โ€‹

    Overviewโ€‹

    At present, ZKP technology is constantly developing and innovating in the scaling and expansion track in Ethereum, especially some zk rollup projects, such as zksync, scroll, starknit, etc. So the main goal of this project is to introduce ZKP technology into the Polkadot/Substrate ecosystem. Polkadot/Substrate natively does not support ZKP, so this project(Zkverse, which means zk universe) will provide zk-related pallets to support substrate and more efficient zk proof generation ways.

    Project Detailsโ€‹

    There are three main goals for project:

    • Integrate some zkp libray(like bellman, plonk library and eg...) into substrate pallet
    • Maximize the efficiency and convenience of zk proof generation(The proof is not generated on the chain, but through some developer friendly libraries(like snarkjs) which will be adapted to the zk lib on substrate-based chain.). This is very important and convenient for scaling. It can realize rollup for app-specific Dapps and greatly increase the throughput of the substrated-based chain. It can be said "Off-chain execution and on-chain verification".
    • Publish some tutorial blogs/demos to let more substrate community developers enjoy the convenience of the above zkp development kits.

    Meanwhile, We know that snakjs and circom are excellent and popular zkp development libraries. They are very popular in the Ethereum ecosystem and can automatically generate verification contract codes. We observed this very good feature, so we want to generate circuit codes more easily through circom, and generate proofs by snarkjs, which will be verified on substrate-based chain. Due to many people using snakjs, and circom is developer friendly, Unlike some domain-specific circuit writing methods, our project can attract many developers who are familiar with snarkjs to develop zkp Dapps in substrate/polkadot ecosystem. They can also enjoy the convenience of developing zkp applications in Polkadot ecosystem. So our main goal is to provide zkp infrastructure that is convenient for Polkadot developers. Also ,we will show a minimal example with Merkle tree and ZKP for rollup.

    Ecosystem Fitโ€‹

    By integrating some very popular ZKP libraries into Substrate pallet, the rollup function of ZKP can be realized on the substrate-based chains, which is convenient for developers to develop zk applications on the substrate-based chains. Although zkp has been relatively active in the Ethereum ecosystem, zkp technology has not been widely popularized in polkadot ecosystem.

    • Zeropool implements zk on the substrate chain, but this library has not been updated for a long time. The substrate has gone through many development iterations and needs to be supported by the latest library.
    • Glacier is building a Distaff VM for zk-STARK proof generation and verification that are used to make private smart contracts and private credential verifications. Also, this project is outdate and not latest.
    • zk-plonk would like to implement Zk plonk pallet. However, plonk takes a long time to generate proofs and is generated on the chain, so there may be problems in efficiency. Also, the library this project using is not the latest.
    • ZK-Snarks tutorial want to introduce the substrate community into the zk-snarks concept๏ผŒbut their ideas and goals have been implmentd since last year. Our project will do more education and involve more zk libraries

    Development Status ๐Ÿ“–โ€‹

    Currently, we have developed a substrate-based chain with zkp protocol and a practical zkp tool (which can adapt to two different zkp libraries to facilitate developers to develop zkp Dapps)

    Development Roadmap ๐Ÿ”ฉโ€‹

    We will implement two different proof systems(groth16 and plonk) separately to meet the needs of different developers

    Overviewโ€‹

    • Total Estimated Duration: 2.5 months

    • Total Costs: 24,000 USD

    Milestone 1โ€‹

    • Estimated duration: 1 month
    • FTE: 1
    • Costs: 7,000 USD

    Implement groth16 pallet in Substrate and develop a tool which can let the proof of snarkjs(off-chain) verified by the bellman library(on-chain). In this way, We can make it convenient for developers to develop zkp applications using the groth16(Bellman is an excellent zkp lib, but it is easy to make mistakes when using bellman to develop circuits, and snarkjs can cooperate with circom to write circuit with few mistakes. So we combined them to make the development of zkp applications more safe and efficient). So far, we haven't seen any team do this, but we think it is very meaningful.

    Zkwasm Rollups Transfer

    Project Overview ๐Ÿ“„โ€‹

    We would like to implement transfer rollups by zkwasm.

    This project enables us high speed and cheap gas fee transfer transactions by zkwasm. The structure is similar to zk rollup but we use wasm as execution environment.

    Overviewโ€‹

    Through this grant, we would like to implement rollup L2 envorinment for transfer transactions powered by zkwasm. The zk rollup allows us high speed and cheap gas fee transfer transactions, and to deposit asset safely. We inherit these features and execute transfer transactions on L2 wasm environment, and prove the validity of state transition by zero knowledge proof. The main differences from zk rollup are two things.

    General purpose rollupโ€‹

    The zk rollup is application specific and it can only execute transfer transactions. Supporting wasm allows us to extend to other functionalities easily as in zkevm and we can reuse the circuit which proves the validity of wasm instruction set. By implementing all wasm ISA, we can finally prove every kind of state transition.

    Implement verification function as built-inโ€‹

    The zk rollup is smart contract project. Users need to deposit their asset to smart contract on mainchain, transfer asset on chain after deposit is confirmed and withdraw asset from smart contract on mainchain. It's complicated process and needed a lot of developer workload. By implementing verification function as built-in, normal node can be L2, aggregate transfer transactions without any customizing and send it to verification on mainchain directly. This has huge usability benefit because users don't care about anything but just transfering asset as usual.

    Project Detailsโ€‹

    zkwasm depends on cryptography primitive and zero knowledge proof library.

    Cryptography Primitiveโ€‹

    In zkwasm scheme, proof generations needs heavy workload. The prover time is latency when users send transaction and verification time is gas cost for miner. We have two approach to resolve this problem. One is the optimization and the other is outsource. We already implemented curve so we would like to optimize and extend it. We are going to implement and optimize as following.

    1. implement RedDSA
    2. optimize jubjub curve
    3. implement client wallet

    RedDSA allows us to generate one time signing key which has same signature with private key. We can outsource the computation when generating proof by generating proof generation key. There are several ways to optimize jubjub so we are going to apply it to our implementation.

    Finally, we are going to implement client libraries.

    Zero Knowledge Proof Libraryโ€‹

    We generate the proof to prove the validity of wasm execution. To prove validity of execution, we use plonk. The main strategy is that writing circuits for each wasm instruction set and generate the proof. The transaction can be divided into sequence of instruction set. To prove each sequence of instruction set are executed correctly, we can prove the validity of transaction. Finally, we aggregate these proof and generate one proof. Users attach it with their transaction and blockchain verify the proof. We are going to implement following libraries to realize this scheme.

    1. implement plookup
    2. implement recursive proof
    3. implement instruction set circuits

    plookup allows us to reduce the complexity of instruction set by using lookup table and recursive proof allows us to generate one proof by aggregating proof for each instruction set.

    Ecosystem Fitโ€‹

    This zkwasm allows us to prove the validity of wasm state transition. In the future, we can extend it to general purpose rollup as in smart contract executions. This is totally compatible with wasm so every project work on wasm can use this library and rollup their transaction.

    Our project specializes in working with Substrate and Polkadot, and if we implement cryptographic libraries and optimize these, it would be used for whole network developer.

    I think this can be applied for XCMP to prove the validity of state transaction.
