+- **Team Name:** Quantum Blockchains

+
+## Project Overview
+
+If this application is in response to an RFP, please indicate this on the first line of this section.
+
+### Overview
+
+QRSub project is committed to advancing the integration of Quantum-Resistant technologies in Substrate-based blockchains. Our aim is to bolster security and ensure sustained protection against quantum computing threats. Building on the foundational work of our company, Quantum Secured Blockchains, QRSub extends these efforts by new developments and conducting critical benchmarks vital for future implementations.
+
+Our project focuses on four key areas of research and development:
+
+- Upgrading standard asymmetric cryptographic algorithms with post-quantum counterparts.
+- Developing a hierarchical deterministic wallet framework suitable for the post-quantum era.
+- Designing quantum-resistant communication protocols for node to node communication.
+- Analyzing and testing the use of quantum entropy in the Substrate based blockchains.
+
+Key Areas of Exploration:
+
+- Refinement of Dilithium PQC Algorithm: Enhancing and evaluating and optimizing our existing Rust implementation of the Dilithium Post-Quantum Cryptography (PQC) algorithm (crystals-dilithium). Additionally, we aim to implement the KYBER key-exchange mechanism in Rust.
+
+- Hierarchical Deterministic Wallets Development: Designing and creating a scheme for Hierarchical Deterministic Wallets, with specific implementations for the Polkadot.js browser extension and for PolkaGate.
+
+- Quantum-Generated Entropy Utilization: Expanding the use of quantum-generated entropy to meet various randomness needs within the blockchain framework. This builds on our previous work in implementing RanDao-like mechanisms and generating secure Pre-Shared Keys (PSK). In particular we are going to explore use of quantum entropy for VRFs.
+
+- Quantum-Resistant Communication Protocols: Developing communication protocols for Substrate blockchains that are resistant to quantum threats based on the post-quantum Key Encapsulation Mechanisms (KEMs) 
+
+- Feasibility study for the use of more advanced securitization of public blockchains through the use of Quantum Key Distribution paradigm. Experimanetal part of the study will be done with our Post-Quantum Key Distribution (pQKD) emulators implemented in software. 
+
+- Performance and Resource Utilization Analysis: Evaluating the impact of quantum-resistant technologies on the performance and resource efficiency of Substrate blockchains. This includes utilizing Substrate-based benchmarks and developing our own benchmarks for aspects not addressed by existing ones. This area is especially crucial because the key lengths of post-quantum algorithms and operation times differ significantly from those of classical algorithms.
+
+
+We are convinced that our project represents a critical step in introducing a vital security dimension, namely quantum resistance, to all blockchains built on the Substrate framework. A successful execution of this project could set a precedent, enabling these blockchains to integrate a novel category of cryptographic technologies that are specifically engineered to withstand quantum computing threats.
+
+Our team is deeply committed to this endeavor, having already developed and partially implemented key components of this advanced technology. However, a comprehensive validation of the entire implementation remains to be completed. This is particularly crucial in terms of its effects on blockchain performance and resource efficiency, which are essential for specific applications such as Digital Identification that demand the highest level of security.
+
+
+### Project Details
+
+The prior work leading to this project has been descibed in the page: **[QSB](https://www.quantumblockchains.io/qsb/)** and in our : **[Whitepaper](https://www.quantumblockchains.io/introducing-quantum-secured-blockchain-a-comprehensive-whitepaper/)**.
+
+Regarding Post-Quantum algorithms, during the previous project we had to modify some parts of Substrate code:
+
+1) primitives/core - added Dilithium2 signature schema (dilithium2.rs)
+2) primitives/io/src/lib.rs - added generation, signing, and verification functions for Dilithium2
+3) primitives/runtime/src/traits.rs - implementation of IdentifyAccount for Dilithium2
+4) primitives/keyring - added keyring for Dilithium2
+
+In this project, we will endeavor to implement the necessary modifications to a palette.
+
+The planned feasibility study aims to determine whether it is both possible and practical for certain types of permissioned blockchains built on Substrate to enhance their security beyond that provided by Post-Quantum cryptography. This study will also explore the potential for paving the way towards the adoption of theoretically secure quantum cryptography.
+
+In terms of utilizing quantum entropy, our goal is to advance beyond the RanDao-like application of entropy, focusing instead on its use in the initialization of Verifiable Random Functions. Additionally, we plan to investigate the use of remote quantum entropy sources, such as those accessible through API3 services, where we already provide quantum entropy (see **[API3 Quantum Entropy Providers](https://docs.api3.org/reference/qrng/providers.html)**). We will also consider local sources of quantum entropy, employing devices that we have designed and manufactured.
+
+
+### Ecosystem Fit
+
+
+- Our project can either establish a quantum-resistant parachain or function as an independent, permissioned blockchain for applications demanding heightened security.
+- Our primary audience comprises developers and users of Substrate-based blockchains who seek advanced security solutions in the quantum era.
+- Our project fulfills the requirements for quantum resistance in Substrate-based blockchains.
+- A similar project, Quantum Guard MVP, is also applying for a grant.
+- Our project distinguishes itself through:
+  - The inclusion of comprehensive benchmarks and tests which lead to real-world implementation. 
+  - The integration of Quantum Entropy into blockchain operations.
+  - The feasibility study backed up by experiments of highest security communication paradigms.

+## Development Status
+
+We have implemented some elements of the project as described in the page: **[QSB](https://www.quantumblockchains.io/qsb/)** and in our : **[Whitepaper](https://www.quantumblockchains.io/introducing-quantum-secured-blockchain-a-comprehensive-whitepaper/)**. However, we did not have enough resources to perform rigorous tests and performance analysis leading to the possibility of public deployment of quantum-resistant public blockchain based on Substrate. For the same reason we could not implememt Hierarchical Wallets based on Post-Quantum approach. While our design of QSB targets private, permissioned blockchain, in this project we perform feasibility study for the use of specific quantum-resistant techniques for public blockchains having the form of e.g. a parachain.
+
+As for academic work leading to our project we have them all listed in ["our papers"](https://www.quantumblockchains.io/our-papers/) section of our site.
