The Ethereum community proposed an upgrade to the eth/73 protocol to support the dissemination of raw signature witness data

Ethereum developer Marchhill submitted the draft EIP-8437, proposing to propagate proof wrapper data through the eth/73 protocol and introducing an optional mode that allows transactions to submit raw signatures to the aggregator without pre-generating STARK proofs.

This proposal supports the direct propagation of certified packages with transactions and performs independent checks of specified programs in resource-constrained sandboxes to verify witness data. The new program does not require the development of native adapters for each signature scheme separately. Additionally, the proposal plans to limit the batch queue size, clean up expired transactions, and recheck records before formally generating proofs to support failure retries.

Currently, the proposal is still in the Draft stage and has not yet been merged. The developer pointed out that VM and key binding consistency verification, cryptographic verification, and performance testing are still incomplete, and benchmarking has not yet been conducted.
