Ethereum Draft Proposes Raw-Signature Proof-Wrapper Propagation
Optional mode 2 wrappers would carry raw signatures, while metered sandbox execution would run fixed programs to check witness data.

The Ethereum community has published a draft proposal for eth/73 that would allow aggregators to receive proof wrappers containing raw signatures without first providing a full STARK proof. The proposal describes metered sandbox execution of fixed programs to check witness data.
Mode 2 wrappers would be optional. They would let raw signatures be submitted to aggregators before a full proof is provided, while the sandbox would run a fixed program to check witness data.
The draft also outlines controls for the proof process: limiting batch queues, removing expired transactions and checking records again before proving. It includes a way to retry submissions. The proposal remains in draft status.
