Ethereum Eyes 4x Gas Limit Boost in Upcoming Fusaka Fork

Ethereum developers are actively weighing a major scalability upgrade that would quadruple the blockchain’s gas limit.
The proposed change, part of Ethereum’s next hard fork codenamed Fusaka, suggests raising the gas limit from its current level to 150 million. This idea is outlined in Ethereum Improvement Proposal (EIP) 9678, introduced on April 23 by Sophia Gold from the Ethereum Foundation.
Gas Limit Expansion as a Core Upgrade
The idea gained traction during the latest All Core Devs Execution (ACDE) meeting, where Ethereum core developer Tim Beiko emphasized making the gas limit increase a flagship feature of the Fusaka release. In a summary shared on April 24, Beiko mentioned that EIP-9678—though unconventional—follows the path of similar precedent-setting proposals like EIP-7840.
Scope of Fusaka May Expand
As testing progresses, developers anticipate that additional EIPs will be needed to support the increased gas throughput. This means the Fusaka fork scope could grow, despite initial plans to finalize it.
The upgrade reflects ongoing efforts to improve Layer 1 performance while maintaining Ethereum’s momentum in an increasingly competitive smart contract landscape.
