An EIP-8437 draft submitted by Ethereum developer Marchhill proposes changes to how proof-related transaction data travels over the eth/73 protocol. The proposal remains a draft and has not been merged.
The draft would propagate a Proof Wrapper over eth/73. It also proposes an optional path in which a transaction submits a raw signature to an aggregator without first generating a STARK proof. An authenticated program package could travel with the transaction; a specified program would then run an independent check of witness data inside a resource-limited sandbox. The proposed approach is intended to avoid building a separate native adapter for each signature scheme.
For batch processing, the draft calls for limits on queue size, removal of expired transactions and a recheck of records before proof generation to support retries after failure. These are proposed behaviors, not evidence of a deployed implementation. Marchhill noted that VM-and-key binding consistency checks, cryptographic verification and performance testing remain incomplete; benchmarking has not yet been conducted.
