Ethereum Researchers Propose SPHINCS- Signature Scheme For Post-Quantum Wallets
TL;DR An Ethereum Research submit proposes SPHINCS-, a stateless post-quantum signature verification scheme optimized for the EVM. The design replaces commonplace SHAKE256 capabilities with EVM-native KECCAK256, permitting a Solidity implementation with out protocol modifications or precompiles. The C13 variant is described as verifying at about 127,000 gasoline with a 3,704-byte signature. The proposal is non-standard…
