Ethereum developer proposes upgrading eth/73 to support propagation of raw signature witness data

Odaily reports: Ethereum developer Marchhill has submitted draft EIP-8437, proposing to propagate proof wrapper data via the eth/73 protocol and add an optional mode that allows transactions to submit raw signatures to an aggregator without pre-generating STARK proofs. The proposal supports propagating certified packages alongside transactions and executing independent checks of specified programs in resource-constrained sandboxes to verify witness data; new programs would not require separately developing native adapters for each signature scheme. The proposal also plans to limit batch queue size, clean up expired transactions, and re-check records before formally generating proofs to support failure retries. The proposal is currently still in Draft status and has not yet been merged. VM and key-binding consistency verification, cryptographic verification, and performance testing remain incomplete, and benchmarking has not yet been conducted.
