SPHINCS minus : Efficient Stateless Post-Quantum Signature Verification on the EVM (opens in new tab)  🔗Hash Chains

Special thanks to Vitalik Buterin, Jean-Philippe Aumasson, Justin Drake, Chelsea Komlo, Mauro Toscano, ZKnox and colleagues from the EF PQ & cryptography team for all the discussions, reviews and feedback. Quantum computers will eventually break ECDSA, the signature scheme that secures Ethereum and Bitcoin accounts today. Recent resource estimates by Babbush et al. [1] bring this timeline closer than previously expected, making post-quantum signature verification at the execution layer an urg...
