Ethereum core developers are considering a major increase to the network gas limit as part of the upcoming Fusaka hard fork, following May Pectra upgrade. Outlined in Ethereum Improvement Proposal (EIP) 9678, the plan suggests raising the layer 1 gas limit to 150 million, a move aimed at enhancing scalability.
The proposal was introduced on April 23 by Sophia Gold of the Ethereum Foundation. During the April 24 All Core Devs Execution (ACDE) meeting, core developer Tim Beiko confirmed that EIP-9678 would be prioritized for Fusaka and merged in the coming week to align client defaults ahead of launch.
Though unconventional, this proactive approach mirrors precedent seen in EIP-7840. Developers expect to uncover protocol changes needed to support the increase, potentially adding more EIPs to Fusaka scope, despite it being previously finalized. The gas limit boost could help scale Ethereum’s base layer but requires extensive testing by client developers to avoid exposing bugs.
Currently Ethereum gas limit sits just below 36 million, following its last validator-approved increase in February 2024. While final control lies with validators, the EIP aims to ensure consistency across clients and guide network-wide adoption of the higher limit.
