The EIP-7825 upgrade is expected to launch alongside Fusaka in December.<\/p>\n
The Ethereum Foundation (EF) has announced a change to the upcoming Fusaka hard fork that will introduce a per-transaction gas limit cap<\/a>.<\/p>\n The EF unveiled the change via its blog today, with the update, also known as EIP-7825, already live on the Holesky and Sepolia testnet networks. EIP-7825 is expected to launch on the Ethereum mainnet when Fusaka goes live in December.<\/p>\n Currently, a single transaction can fill an entire block’s 45 million gas limit, which could inhibit parallel execution and open the door to Denial of Service (DOS) attacks. The change will set a per-transaction gas limit of 16.78 million to mitigate potential issues.<\/p>\n The change will have little to no impact on the average user and mostly affects developers with contract or script designs that involve batching.<\/p>\n Toni Wahrstatter, a researcher at the EF, posted on X <\/a>today about the change, saying that developers should consider testing on the Sepolia testnet, where the cap is live, and double-check signatures, deployers, tooling, and transaction sizes on their contracts.<\/p>\n \u201cThis is one step toward parallel execution (see EIP-7928: Block-level Access Lists). By enforcing predictable transaction sizes, Ethereum prepares for higher throughput and safer scaling,\u201d concluded Wahrstatter.<\/p>\n Fusaka lays the groundwork for a future pivot towards parallel execution<\/a> on Ethereum \u2014 a modern transaction processing model in which transactions are processed simultaneously rather than in the traditional sequential order.<\/p>\n
