Quantum Resistant Ledger

Quantum Resistant Ledger (QRL) is a Layer 1 blockchain launched on 26 June 2018 that is designed to remain secure against attacks from both conventional computers and quantum computers. The project was founded by Peter Waterland, who identified that the cryptographic signature schemes used by networks such as Bitcoin and Ethereum could be broken by sufficiently powerful quantum computers. QRL positions itself as a long-term alternative for users who want a payment and decentralized communication network that is hardened against that specific class of future threat.

QRL uses the RandomX proof-of-work consensus algorithm, meaning miners compete to solve computational puzzles in order to add blocks, with a target block time of one minute. Rather than the elliptic-curve signatures used by most blockchains, QRL relies on hash-based signature schemes that are considered resistant to quantum computing attacks. The QRL token is the native unit used to pay for transactions and to reward miners who secure the network.

The data stored for this asset does not include a fee revenue figure, so fee-based measures such as price-to-fees ratios are not available on this page. Fees on the network are paid by users initiating transactions and are collected by miners as part of the block reward system. Of the maximum supply of 105,000,000 QRL, approximately 78,392,960 tokens are in circulating supply, representing about 74.66 percent of the maximum, and the dilution overhang is recorded at 0.0 percent, meaning no additional supply beyond the maximum is pending issuance. The 24-hour turnover figure stands at roughly 0.068, indicating the share of circulating supply that changed hands in the most recent 24-hour period.
