Overview
Quantum Resistant Ledger (QRL) is a blockchain project built around the concern that sufficiently powerful quantum computers could break the signature schemes used by existing cryptocurrencies. Founder Peter Waterland designed the network after researching how the elliptic curve signatures (ECDSA) used by Bitcoin and Ethereum might be vulnerable to quantum attacks. The initial implementation was written in Python, and the mainnet launched in 2018.
At its core QRL uses XMSS (eXtended Merkle Signature Scheme), a hash-based post-quantum signature algorithm documented by the IETF as RFC 8391. The network produces blocks via proof-of-work, and its native token, Quanta (QRL), is used for transaction fees and mining rewards. Beyond signatures, the project has aimed to offer quantum-resistant features such as decentralized messaging, multi-signature addresses, and on-chain notarization.
