Ethereum Research Proposal Targets Post-Quantum Wallet Security At Low Gas Cost

A new Ethereum Research proposal is putting post-quantum wallet security back in focus, outlining a practical way to verify quantum-resistant signatures on the EVM without requiring a full protocol-level upgrade.The proposal, published by Ethereum researcher nicocsgy, explores an EVM-optimized version of the SPHINCS+ stateless post-quantum signature scheme. The design aims to make quantum-resistant verification more practical for wallet use cases by adapting the scheme to Ethereum’s existi
