Draft:Quantum Resistant Ledger


The Quantum Resistant Ledger (QRL) is a blockchain network and platform designed to be resistant to attacks from both classical and quantum computers.[1][2][3][4][5][6] To achieve quantum-resistance, The QRL uses hash-based cryptography, XMSS (eXtended Merkle Signature Scheme)[3][7][8] which NIST plans to approve[9] to provide account security[10], rather than the more common Elliptic Curve Digital Signature Algorithm (ECDSA) found in other blockchain networks such as Bitcoin[11][12]. Although a quantum computer powerful enough to threaten the security of ECDSA[13] does not yet exist, Peter Shor has demonstrated[14][15][16] that a sufficiently powerful quantum computer could perform factorization exponentially faster than the best available classical computers[17], which has the potential to render ECDSA and related public-key infrastructure insecure[18][19]
