[Ethereum Draft Proposes Bulk Proof Sponsored Payments] According to a report by Jinse Finance on November 15th, crypto.news, Ethereum contributor Marchhill submitted a draft (PR 12664) to the EIP repository on November 13th, proposing to enable universal proof verification and sponsored batch processing, allowing multiple transaction claims to share a single proof while retaining their respective payments and signatures. The draft proposes activating the LEANSTARK_SCHEME reserved in EIP-8288, with sponsors paying for each retained batch leaf, and member transactions paying according to their respective claims; builders can include any valid subset without members re-signing, individual transaction nonces and receipts remain unchanged, and payment matching is verified during finalization. The tentative fee structure is: native verification 15,400 gas, general verification 572,000 gas, intrinsic proof share 5,100 gas, leaf payment 675,000 gas, and batch claims 4,200 gas. This requires joint calibration and does not constitute a final fee rate. This submission is still a draft PR, replacing the previous one 12654. It has not been assigned an EIP number or discussion thread, has not been adopted as a network upgrade, and has no mainnet activation date. Performance testing of all blocks must be completed before activation.
