About Quantum Resistant Ledger
The Quantum Resistant Ledger (QRL) project is designed to be fully post-quantum secure using PQ-CRYPTO recommended cryptography. Following nearly two years of development, the successful launch of the QRL Mainnet in June 2018 saw the creation of the world's first fully post-quantum secure blockchain ledger project. The QRL utilises a hash-based one-time extended merkle tree signature scheme (XMSS) instead of ECDSA. Launched with proof-of-work block selection via the cryptonight algorithm, transition to POS with a signed iterative hash chain reveal scheme which is both probabilistic and random is in the project roadmap. Hash-based signatures mean larger transactions (2.8kb per tx, binary), longer keypair generation times and the need to record 'state' of transactions as each key pair can only be used once safely. Merkle tree usage enables a single address to be used for signing numerous transactions (up to 2^13 computationally easily enough). Transactions have an incremented nonce to allow wallets to know which MSS keypair to use - currently XMSS/W-OTS+ are natively supported. The QRL provides a post-quantum secure of value as a cryptocurrency whilst the project ecosystem allows blockchain applications to be easily built upon a provably quantum resistant foundation.
