The Quantum Resistant Ledger (QRL) project is a public blockchain ledger designed to be specifically secure against quantum computing (QC) advances. Unlike existing ledgers, such as bitcoin or ethereum, the QRL is specially designed to use a form of post-quantum secure signature for transactions called XMSS. The QRL also uses a low power proof-of-stake (POS) algorithm which again utilises iterative hash-chains and provably secure hash-based pseudo random number functions. The POS algorithm is designed to have zero reliance upon conventional signatures which are vulnerable to a sufficiently powerful QC and allows nodes to run on low power devices such as raspberry PI’s or laptops and passively earn income by staking.
