Quantum Resistant Ledger (QRL) is a pioneering cryptocurrency designed to safeguard digital assets against the looming threat of quantum computing. Born in 2016, QRL was specifically crafted to resist potential attacks from powerful quantum computers, which could potentially compromise traditional cryptographic systems. Utilising a cutting-edge post-quantum secure signature scheme called XMSS (eXtended Merkle Signature Scheme), QRL ensures long-term security and integrity for its users. As an open-source, community-driven project, it focuses on fostering a safe ecosystem for blockchain transactions, adhering to the ethos of decentralisation. The network operates on a proof-of-stake (PoS) consensus mechanism, promoting energy efficiency while maintaining robust security measures. By preparing today for the technological challenges of tomorrow, QRL is a forward-thinking solution that prioritises security and resilience.
