Ethereum’s core developers are pushing forward with a significant proposal to boost the gas limit for the upcoming Fusaka hard fork, following the Pectra upgrade. The proposed change, detailed in Ethereum Improvement Proposal (EIP) 9678, suggests raising the gas limit to an impressive 150 million units. Sophia Gold, a developer from the Ethereum Foundation’s protocol support team, presented this proposal on April 23rd. During a recent All Core Devs Execution (ACDE) meeting, discussions focused on making this increase a priority for Fusaka, as highlighted by Ethereum core developer Tim Beiko in an April 24th meeting summary. An EIP has been drafted to align client defaults and ensure this is prioritized. Although unconventional, this approach echoes precedents like EIP-7840. This plan involves merging the EIP early next week for formal inclusion in the next ACDE. The developers anticipate identifying necessary protocol changes to support a higher gas limit, potentially leading to additional EIPs being incorporated into Fusaka. Notably, the focus is on addressing the need for increased scaling of layer 1 execution by introducing new features. However, this approach demands guidance from execution layer developers, who will need to address potential client bugs that may arise as part of a higher gas limit implementation. This requires time for clients to be tested and resolved before Fusaka goes live in late 2025. The motivation behind the increase lies in the desire to enhance scalability, but it also necessitates careful coordination between execution layer and protocol developers. The goal is to ensure all clients update their defaults according to the EIP’s specifications before Fusaka officially launches. This aligns with validators’ efforts in February 2023, when they increased the network’s gas limit to approximately 36 million units per block.
