Quantum Resistant Ledger (QRL)
Also known as: Quantum-Secure Blockchain, Post-Quantum Ledger, QRL Chain
A blockchain designed to be secure against future quantum computer attacks using post-quantum cryptography.
Quantum Resistant Ledger (QRL) is a blockchain built from the ground up using post-quantum cryptographic algorithms, specifically designed to resist attacks from quantum computers. Unlike traditional blockchains that rely on elliptic curve cryptography (ECC), QRL employs hash-based signatures (XMSS) that are secure against Shor’s algorithm. QRL aims to future-proof digital assets by addressing the risk that quantum computing poses to current cryptographic standards. It also supports smart contracts and token issuance in a quantum-secure environment. The project emphasizes security, scientific research, and long-term resilience.
