Ethereum core developers are preparing to quadruple the network’s gas limit as part of the next major upgrade — the Fusaka hard fork, following Pectra. According to EIP-9678, introduced on April 23 by Ethereum Foundation dev Sophia Gold, the proposal aims to test raising Ethereum’s gas limit to 150 million, a significant leap from the current ~36 million.
This upgrade could mark the largest gas limit expansion in Ethereum’s history, reflecting developers' growing appetite for layer 1 scalability without the need for new features. The gas limit controls how much computation can be packed into a single block, directly impacting transaction throughput.
$ETH core dev Tim Beiko noted that the Fusaka fork will prioritize this change, despite the fork's scope being "finalized." Developers anticipate bugs may surface at higher gas levels, prompting a need for coordinated updates across client software — hence the decision to formalize it as an EIP.
While validators ultimately control the gas limit, an EIP ensures uniform default settings across all Ethereum clients by the time Fusaka is activated — potentially in late 2025.
The motivation? Speed and scale. With Pectra set to hit mainnet in May 2025, Ethereum continues evolving toward higher performance without sacrificing decentralization.
As Beiko put it: “We expect to identify changes in-protocol to support a higher gas limit,” signaling that the network is getting ready for heavier workloads and a more efficient base layer.
For now, the gas limit stands at just under 36 million, up from 30 million in 2021 — but Fusaka could be the moment Ethereum truly levels up.
