Post-Quantum Cryptography Expert Joins QRL
The Quantum Resistant Ledger (QRL), a blockchain focused on post-quantum security, has appointed Dr. Joseph Kearney as a Technical Advisor. The move aims to add academic and operational depth to the project's efforts in creating a blockchain secure from attacks by future quantum computers. Dr. Kearney's expertise is expected to guide QRL's technical roadmap.
- The "harvest now, decrypt later" threat underscores the immediate need for post-quantum security. Malicious actors are currently collecting encrypted data from blockchains with the intention of decrypting it once powerful quantum computers are available. A Federal Reserve study highlighted that this makes data already on quantum-vulnerable ledgers impossible to retroactively protect. - QRL has been quantum-resistant from its inception in 2018, utilizing the eXtended Merkle Signature Scheme (XMSS), a hash-based signature system approved by NIST. Unlike many other blockchains that use elliptic curve cryptography, which is vulnerable to quantum attacks, QRL was designed specifically to address this future threat from day one. - Dr. Kearney's expertise is in quantifying and mitigating the risks of quantum attacks on blockchain technologies. His doctoral thesis was on "Quantum Advantage On Blockchain Technologies," and he has published research on the "Vulnerability of blockchain technologies to quantum attacks." - The upcoming QRL 2.0 upgrade, codenamed Project Zond, will introduce a proof-of-stake consensus mechanism and Ethereum Virtual Machine (EVM) compatibility. This will allow developers to migrate existing Solidity-based projects to a quantum-secure environment with minimal adjustments. - As part of the QRL 2.0 upgrade, the network will integrate CRYSTALS-Dilithium (ML-DSA), a post-quantum digital signature algorithm approved by the U.S. National Institute of Standards and Technology (NIST). This adds another layer of vetted, standardized quantum-resistant cryptography to the platform. - Other blockchain projects are also addressing the quantum threat; for instance, Algorand has implemented the Falcon signature scheme. However, QRL's singular focus since its launch has been on providing a quantum-secure store of value and communication layer. - Dr. Kearney will serve as a Technical Advisor, focusing on the technical integrity of the QRL ecosystem as it transitions to the QRL 2.0 network. His role is particularly crucial as the upgrade introduces more complex functionalities like smart contracts.
