Ethereum Draft Proposes Sponsored Batches for General Proof Verification

An Ethereum community draft would add general proof verification and sponsored batches, letting sponsors pay for aggregated claims while members cover the claims they submit.

The proposal would enable LEANSTARK_SCHEME, a scheme reserved by EIP-8288. Under the design, a sponsor would pay for an aggregated node containing multiple claims, while each member would pay based on the claims they submit.

Any valid subset of claims could be included without re-signing. The draft also specifies verifier identity, resource boundaries and dependency digests. Activation would depend on performance benchmarks.

The proposal follows earlier Ethereum work on proof aggregation, including an EIP draft focused on transaction proofs across the mempool. The new draft centers on general proof verification and dividing batch costs between sponsors and members.
