Ethereum Draft Proposes Shared Payments For Batch Proofs

Ethereum contributor Marchhill has submitted a draft proposal to the Ethereum EIP repository to enable generic proof verification and sponsored batch processing, according to CryptoNews. The mechanism allows multiple transaction claims to share a proof while retaining separate payments and signatures.

Sponsored Batch Processing and Fees

Under the proposed structure, sponsors can cover batch proofs while member transactions pay for their individual claims. Valid subsets could enter a block without requiring members to sign their transactions again, preserving individual transaction nonces and execution receipts. The draft supersedes an earlier submission, pull request #12654, and activates the LEANSTARK_SCHEME reserved in EIP-8288.

The supplied revision lists provisional charges of 15,400 gas for native verification and 572,000 gas for ordinary generic verification. It assigns 5,100 gas to the intrinsic proof share, 675,000 gas to a leaf payment, and 4,200 gas to a batch claim. Resource controls include a provisional block limit of 16,384 distinct dependencies and a block-wide leaf limit of up to 256 claims, with each proof step supporting 16 inputs.

Performance and Activation Requirements

Before activation, the proposal requires performance measurements covering the complete processing schedule, late sponsor repair, and per-proof charges that fit within transaction gas limits. The submission remains a draft pull request under development with no assigned EIP number or mainnet activation date.
