+ +==Abstract== + +The purpose of this RIP is to modify the Ravencoin consensus core protocol to enable Vault assets. Vault assets are fungible assets on the Ravencoin blockchain which have native value in the form of Ravencoin currency (ie a "face value"). They also pay/cost an interest/demurrage % rate of the "face value" per day or a fixed quantity of RVN per day. + +==Motivation== + +The Ravencoin protocol is an extension of the bitcoin protocol design which natively supports the creation and management of assets. But adoption and use of those assets depends on the traditional legal and banking systems to establish the link of value between a Ravencoin asset and a real world asset. The result is that the rate of adoption of Ravencoin is determined by the rate of adoption of blockchain technology by the traditional legal and banking systems. Currently, Ravencoin lacks the ability to assign value to on-chain assets denominated in the local Ravencoin RVN currency. This is an oversight because the flexibility built into the Ravencoin protocol can fully support this with the ability to securely and atomically trade between the asset and the currency in a single transaction. Enhancing an asset with the ability to carry a face value also makes it possible for the asset to implement a daily interest rate, either positive (earnings) or negative (demurrage) or a fixed daily positive or negative quantity of RVN , which opens many more interesting applications. + +I, LSJI07, have recorded it here for posterity in case Hans Schmidt or others choose to work on this. People can move on, and someone else may have interest. + +Q & A + +Q: Why is this desired? +A: This capability would give Ravencoin powerful functionality to more fully participate in the cryptocurrency and fintech ecosystems. + +Q: Can you give an example? +A: Business founders could distribute assets as ownership shares, or people could buy those assets as always envisioned for Ravencoin assets. But now, the profits from the business can be used to do "monetizeasset" transactions, thereby giving the distributed assets immediate value. That value could be hodled or traded. Or it could be cashed out at any time by doing a "meltasset" and selling the resultant Ravencoin currency on any of the exchanges. This model is especially powerful for businesses which earn their income in cryptocurrency, but it could be used for any business. + +Q: Would the sale and transfer price of an asset always be determined by the quantity of Ravencoin currency held in escrow for that asset? +A: No. Assets would have a "face value" determined by the escrow amount. But assets would have a higher trading price determined by the market based on people's expectations for the future value of that asset as well by the perceived value of the company or community which the asset represents. Additionally, there may be real world assets attached by traditional legal means to the on-chain asset which are not visible on-chain but which can increase its trading price. + +==Methodology== +At present, the nodes keep track of the UTXO set for both RVN and assets. For assets, that implies keeping track not only of the creation and transfer history bitcoin-style, but also of some metadata (units, reissuability, etc). The nodes already have to track that metadata and changes to it just like UTXO changes. This concept adds an additional Raven_Fund metadata number to every asset name, which represents the number of RVN backing that asset name. All nodes know what the current Raven_Fund number is for each asset name, just as they know the other metadata and the UTXOs from the transaction history. The sum of all the Raven_Fund (RF) numbers plus the sum of all the RVN at addresses is the total RVN supply, which is fixed by the whitepaper and changes only due to miner rewards. That can be thought of as an extended UTXO dataset, and the RFs for all the assets can be thought of as pseudo-addresses. + +When new Vault assets are created (issued) for the first time, an amount of RVN is set aside for the Raven_Fund (RF) for that asset name. After the mintasset command is executed, each Vault asset by that name will have a "face value" equal to the RF quantity of RVN divided by the quantity of Vault assets which were issued. + +Anyone can transfer RVN from an address into an asset name's Raven_Fund using a new RPC which specifies the asset name and the qty of RVN, which increases the "face value" of all the assets issued with that name. This is a "monetize" transaction. The nodes track these transfers as their extended UTXO dataset and know where the RVN are. The "face value" of any single asset token is equal to the number of RVN in the Raven_Fund divided by the number of tokens in circulation, and all nodes know that number. + +Assets can be transferred as usual. If the recipient of some assets wants to "cash them in", then he can execute a "melt" on those assets. To support this, there is a 2nd new metadata number attached to every asset name which I call Authorized_Quantity (AQ), and it is also tracked by all nodes as part of the extended UTXO dataset. The sum of all the assets at addresses plus the AQ for that asset name equals the total number of assets issued by that name. The AQ is the number of existing but inactivated assets temporarily removed from circulation just as the Raven_Fund is the number of RVN temporarily removed from circulation. A "melt" operation increments the AQ number for the asset and removes the assets from the owner's address. It also decrements the Raven_Fund number for the asset, and puts RVN into the owner's address. AQ and RF can be thought of as pseudo-addresses and all nodes track their change as part of the extended UTXO dataset. + +An "unmeltasset" operation allows the person controlling the owner token to take inactivated Vault tokens from AQ, spend RVN into RF to catch those assets back up to the current "face value" of the assets currently in circulation, and reactivate those assets (put them back into circulation). + +A "remintasset" operation is like an "unmeltasset" operation except that it creates new assets out of thin air instead of reactivating tokens which were inactive in AQ. Note that this can only be done if the Vault asset was set as "reissueable" when first issued. An "unmeltasset" operation can be done even on an asset which is non-reissuable because does not result in more assets in existence than originally authorized. + +A blockchain project is currently being developed and carried out, branded as EVRmore, as a code fork of Ravencoin. This should enable us to watch and test out these ideas and add them at a later date, if appropriate for the Ravencoin community. + +==Benefits== +A Simple Use Case Example: +Currently, Ravencoin depends entirely on the traditional legal system to give value to on-chain asset tokens tied to real-world assets. The RavenVault extension provides the ability to choose any business model you prefer ranging from fully on-chain value to traditional legal value or any mix in between. + +Let me describe a simple on-chain example. You might decide to start a company called Ravenco which provides security services and products, along with Joe and myself and 4 other friends. So you issue the "^MYRAVENCO" asset having 10 tokens. You keep 3 tokens for yourself, Joe gets 2 tokens for his expertise, I get 1.9 tokens because I am in charge of security, our accountant friend gets 0.1 token because the chain does most of the work, and 3 other friends get one token. You might write a subscription security blog, and the on-line shopping cart, which collects payment in RVN, immedicately "monetizes" the RVN to the Ravenco Raven_Fund. You also give your subscriber list to me. I teach self-defence classes, and with the money I collect, I buy RVN and "monetize" them to the Raven_Fund. After a while, the Raven_Fund contains 1000 RVN, so every Ravenco token has a face value (book value in Wall Street lingo) of 100 RVN, and your 3 tokens are worth 300 RVN. Then one of our friends needs cash, so he "melts" his token, which pays him 100 RVN and increases the Authorized_Quantity to 1. +Your 3 tokens are still worth 300 RVN. After that, you could "unmelt" that AQ token to a new business partner. Or you could remint new tokens for new investors. But either way, I don't have to worry about you diluting my value because the "unmelt" and "remint" commands fail unless you provide enough RVN to cover the face value of the tokens being put into circulation. So new partners have to buy-in at a minimum of face value. But of course, you could provide more value during the "unmelt" or "remint". Perhaps Craig Wright would desperately want to buy the token because he thinks that Ravenco will take over the world, and he is willing to pay 1.2 million RVN. Then you could "unmelt" the token from AQ to him while specifing the fund_address as his address which contains the 1.2 million RVN. After that transaction, your 3 Ravenco tokens are worth 360270 RVN. So you and I and our friends "melt" our tokens to get our RVN and go start a new company. All enforced on-chain. With more security than a programmed smart contract could ever offer. + +The Ravenco asset has a single Raven_Fund number attached to it which represents the number of RVN taken out of circulation and put into escrow to back that asset. So if there are 1000 RVN in the Ravenco Raven_Fund and there are 10 Ravenco tokens currently in circulation, then each token has a face value of 100 RVN. In my example, the Raven_Fund accumulated 1000 RVN from business profit "monetize" transactions, then dropped 100 RVN when our friend "melt"ed his token, then added 1.2 Million RVN when a token was "unmelt"ed to Craig. So at the end, there are 1000-100+1200000 RVN in the Raven_Fund of Ravenco and still 10 tokens in circulation. So dividing the Raven_Fund quantity by the token count of 10 gives each token a face value of 120090 RVN available by "melt"ing. + + +==Implementation== + +Naming Rule: + +Vault assets are a special type of root asset or subasset. They follow the same naming rules as root assets and subassets except that their name must always start with the ^ symbol (an upside-down "v"). +This naming convention makes it clear that the asset is a Vault asset which has a face value and which pays/costs an interest/demurrage rate from/to an address. +Vault assets therefore look something like ^MYNAME/^MYSUBNAME +Vault asset names may only be issued by the owner of the root asset of the same name. Thus ^MYNAME may only be issued by the owner of MYNAME! + +New data maintained by the nodes for each fungible Vault asset or Vault subasset: +*RF = Raven_Fund = The quantity of RVN currency held in escrow for this fungible Vault asset name, +*AQ = Authorized_Quantity = The inactivated quantity of this Vault asset name which has been authorized but is not currently in circulation and which has no value, +*Interest_Rate = A signed float which represents the interest/demurrage % rate paid/charged in RVN per day for holding the Vault asset. The payment/charge is against the face value of the Vault asset. The payments/charges are made automatically on a daily basis by the consensus code. +*Interest_Amount = A signed float fixed value paid or charged in RVN per day for holding the Vault asset. +*Interest_Address = The address from which interest payments are charged to increase the Vault asset "face value" or into which demurrage payments are paid from the Vault asset "face value". + +==Vault-related RPC Commands== + +Mint=> ''mintasset'' +This issues a Vault asset and then does a ''monetizeasset''. +It is similar to a normal root asset or subasset ''issueasset'' except that it also creates and allows setting the Vault-specific metadata fields as defined: +*RF = Raven_Fund +*AQ = Authorized_Quantity +*Interest_Rate = Signed % interest/demurrage of "face value" RVN per day. +*Interest_Amount = Signed float fixed value RVN per day. +*Interest_Address = The address for interest/demurrage payments/charges + +Monetize=> ''monetizeasset'' +This removes a designated qty of RVN currency from the designated address and from circulation and puts it into the RF escrow account associated with this Vault asset name. This increases the prorated RVN currency "face value" of each Vault asset because it increases RF. It can be executed as often as desired to increase the "face value" of the Vault assets in circulation. + +Melt=> ''meltasset'' This inactivates the designated qty of Vault assets by removing them from the designated address and from circulation. It increases AQ. It pays out a prorated qty of RVN from escrow (reduces RF) and puts them into the designated address and back into circulation. + +Unmelt=> ''unmeltasset'' +This reactivates the designated qty of Vault assets by moving them from AQ into the designated address and back into circulation. It reduces AQ. It requires a payment of RVN currency equal to the current per-asset "face value" times the qty of Vault assets being unmelted If this command is executed with qty=0, it prints the current values of AQ and RF to reveal the amount of RVN currency which will be required for an unmelt. + +Remint=> ''remintasset'' +Reissue a fungible Vault asset. If the Vault asset was previously monetized, then also lock raven into the RF escrow attached to this Vault asset name. That is, if RF>0 the fund_address must contain sufficient RVN currency equal to the current per-asset "face value" times the assetqty being reissued. It increases RF. Note that Interest_Rate and Interest_Address are decided during Mint and cannot be changed during a Remint operation. + + +==Vault-related RPC Command Details:== + +Mint => ''mintasset "asset_name" assetqty rvnqty "fund_address" "to_address" interest_rate interest_amount "interest_address" "mint_burnfee_address" fee_amount "fee_address" "(change_address)" (units) ( reissuable ) (has_ipfs) "(ipfs_hash)"'' +*mintasset is like a issueasset but for a Vault asset. +*mintasset requires payment of a RVN burn fee, just as issueasset does. +*Issue a fungible Vault asset and lock RVN into an escrow RF attached to this asset name. +*Asset names must begin with ^.

Since any number of RVN are allowed when creating the Raven_Fund for an asset or when adding to the Raven_Fund, it is possible for the "face value" of a single token to be a number with an infinite number of decimal places. + +For instance: If a "mintasset" is executed to create 12 asset tokens backed by a Raven_Fund of 4 RVN, then each token will have a "face value" of 0.33333... RVN. +Likewise, a "mintasset" command creating 12 assets with a Raven_Fund of 3 RVN, followed by a "monetizeasset" command of 1 RVN to the same asset, will create the same result. If round-off errors are not taken into account, the movement of RVN back and forth between circulation and Raven_Funds can impact the total RVN supply. + +In order to accurately preserve the total RVN supply in existence, round-off errors are best handled as follows: +*Any number of RVN are allowed during "mintasset" or "monetizeasset" commands. +*When doing "face value" calculations, round up for "unmeltasset" and "remintasset" commands; round down for the "meltasset" command. In other words, unmelt and remint will always require a small over-payment, while melts will always yield a small under-payout. This will insure that the holder of the asset owner token cannot repeatedly unmelt or remint and then melt to extract RVN from the Raven_Fund. Also, round-off errors will accumulate in the Raven_Fund, which slowly raises the face value of the remaining tokens in circulation. +*If all tokens are melted (that is, all tokens are moved from circulation to AQ), the amount payed out during the final melt command should be set equal to the value of the Raven_Fund balance. This insures that the final Raven_Fund=0 and the total RVN supply is accurately maintained. + +==Addendum - RavenVault-Plus== + +RavenVault-Plus is a further modification of the RavenVault proposal to allow extraction of face value from assets. +Its primary feature is that it provides a mechanism for DAO cash-outs. + +Vote for Unmelt at face value doesn't change value of each outstanding token, but reduces equity share & thus voting power per token +Vote for Remint at zero value useful for funds withdrawal off-chain; reduces value per token and equity share per token. + +Voting implementation: + +Each token has metadata which specifies: + +*Is a vote required to authorize Unmelt at face value. +*Is a vote required to authorize Remint at zero value. +*If a token is not re-issuable, then there is nothing to vote about. +*If a token is re-issuable, then during a re-issue the meta-data can be made more restrictive but not more permissive +*Votes are always won by 51% of the vote. + +All tokens vote by design: The vote of each asset UTXO is part of the asset transfer transaction, and stays valid until changed by the next transfer. + +*Disadvantage: +**requires sending all your tokens to a new address to change the vote for those tokens. +*Advantage: the token owner sets the inital default when distributing the tokens. +**The wallet default should be to set all the votes to permissive on each transfer. +**The vote could be encoded into asset transfer transactions by the addition of a new "vote" field. + +==References== +https://hans-schmidt.github.io/mastering_ravencoin/evermore_defi_roadmap/Vault_Assets-_Fungible_Assets_with_Native_RVN_Face_Value.html \ No newline at end of file From 45108cdb94fbc3fbc430f95187b6d69a8ada5f41 Mon Sep 17 00:00:00 2001 From: lsji07 <39772657+lsji07@users.noreply.github.com> Date: Tue, 20 Sep 2022 21:23:31 +0100 Subject: [PATCH 2/2] Update rip-0021.mediawiki --- rip-0021.mediawiki | 6 ++---- 1 file changed, 2 insertions(+), 4 deletions(-) diff --git a/rip-0021.mediawiki b/rip-0021.mediawiki index bece8ea..50c60af 100644 --- a/rip-0021.mediawiki +++ b/rip-0021.mediawiki @@ -149,8 +149,7 @@ Melt => ''meltasset "asset_name" assetqty "from_address" "to_address" fee_amount **"from_address" (string, required), address from which Vault assets will be removed and inactivated **"to_address" (string, required), address where extracted "face value" RVN will be put **"fee_amount" (numeric, required) the number of ravencoins to be paid in fees for this transaction -**"fee_address" -(string, required), address from which the ravencoin fee will be taken +**"fee_address" (string, required), address from which the ravencoin fee will be taken **"change_address" (string, optional, default=""), address the Ravencoin change from the fee will be sent to.
