The Ethereum Foundation has issued a notice urging all Blob proposers to update their software in response to issues on Sepolia related to EIP-7549. This update is necessary to transition from generating Blob Proofs to Cell Proofs, which are required due to changes in the proof format. EIP-7549 enhances data availability by allowing specific parts of a Blob to be downloaded rather than the entire Blob. The transition involves recomputing Cell Proofs, and clients like go-ethereum will manage this change in eth_sendTransaction and eth_sendRawTransaction RPC calls, with an expected processing time of about one second. Blob transaction initiators are advised to adopt Cell Proofs to minimize RPC overhead. Transactions present in the pool during the fork may be dropped or converted to Cell Proofs, and any not included in the blockchain should be resent using Cell Proofs. Major client libraries now support the ComputeCellsAndKZGProofs() function to facilitate this transition.
