Ethereum contributor Francesco Risitano, who goes by @frisitano, has submitted draft proposal EIP-8440, described as an execution chain proof. The draft uses a recursive zero-knowledge proof mechanism to prove the validity of all execution payloads from the head beacon block back to the genesis beacon block, while binding that proof to the beacon chain. According to the proposal description cited by ChainCatcher, a node could use a single proof to establish full execution validity from a weak subjectivity checkpoint to the latest block header. The intended result is constant-time chain synchronization, replacing the need to verify the full execution history step by step in the sync process. The proposal is framed as a draft and was reported by ChainCatcher as a new Ethereum Improvement Proposal submission.
