- Ethereum’s Fusaka upgrade aims to increase the gas limit to 150 million, boosting scalability.
- The gas limit increase is expected to improve Ethereum’s Layer 1 execution and transaction capacity.
- Validators will modify settings for Fusaka, enhancing Ethereum’s transaction processing and network efficiency.
Ethereum developers are pushing for the upgrade to increase the gas limit as part of the upcoming Fusaka update. This proposal, submitted in the Ethereum Improvement Proposal (EIP) 9678, proposes increasing the gas limit to 150 million. This will be implemented in the Fusaka hard fork, scheduled to occur in the fourth quarter of 2025. This process is intended to make Ethereum more scalable without adding complicated new features to the network.
However, the proposal was made by Sophia Gold, a member of the Ethereum Foundation’s protocol support team, on the 23rd of April. It was a topic of talk during the latest All Core Devs Execution, commonly referred to as the ACDE meeting. Developers expect that the increase in the gas limit will enable Ethereum to process more transactions per second. Thus, the expansion of the limit can help the network improve its Layer 1 capability execution, which remains critical to its long-term scalability.
Ethereum’s gas limit is 36 million as of today, up from 30 million in February 2025. The previous increase was found to improve the network performance and capacity and facilitate efficient management of the number of transactions. However, with the upcoming increase in gas limit. The Ethereum blockchain may further expand the overall capacity for meeting more demand. With an increasing number of Ethereum users, developers are beginning to seek ways to scale the network.
Ethereum Gas Limit Challenges
While, Fusaka is planned to be launched by the end of 2025 after the launch of Pectra in May of 2025. However, developers also note that the gas limit increase can have its drawbacks, though it is considered one of the most important solutions for Ethereum’s scalability. Some of these challenges include handling vulnerability on the client side that might arise due to an increased gas limit. Efforts are being made to ensure that the update does not interfere with the current operations of the clients.
Tim Beiko, a core developer, noted that the validators would be involved in modifying the gas limit. Fusaka will require clients to adjust certain settings in their accounts before the transition to the new version. This update can help Ethereum handle more volumes of transactions and improve the conducive flow of the network. The Fusaka hard fork is expected to fix some of the current problems faced and make Ethereum a faster and more efficient platform for the expanding ecosystem.
However, the increase of the gas limit is discussed as a necessary measure for improving the platform’s further development. By increasing its TPS, Ethereum has the potential to leverage it in decentralized finance and other sectors.
