A Solution for 7 Cents? Ethereum Researcher Shares a Plan for Quantum Security U.Today

• SPHINCS is a set of settings optimized for the EVM, based on SPHINCS and the latest developments in compact hash signatures. The goal is simple: to reduce verification costs on the blockchain without the need for precompilation or protocol changes.

Ethereum developers believe that the Solidity implementation of SPHINCS, which complies with NIST standards for short signatures, can already verify standard post-quantum signatures on Ethereum at an acceptable cost (150,000 gas). A formal proof of the verifier is presented using Lean 4 and Verity.

Later, more non-standard, radical options will be considered that replace standard hash components with a Keccak function built into the EVM and reduce the signature size to a level suitable for on-chain wallets. For all these variants, we will examine the trade-off between verification cost, signer effort, signature size, and the limit on signatures per key. “,”detected_source_language”:”RU
