Ethereum has lifted the gas limit per block to 60 million, the highest level in four years, and the change takes effect now. The move aims to keep queues short as demand spikes before the Fusaka upgrade scheduled for 3 December 2025, letting the chain handle more transactions in the interim. The increase precedes deeper protocol changes that will underpin higher throughput without sacrificing decentralization.
The 60 million gas limit in Ethereum is effective immediately to ease congestion ahead of Fusaka on 3 December 2025. By allowing more operations per block, the chain can process more activity while demand rises before the upgrade goes live, helping keep transaction wait times shorter.
The 60 million cap is not the final target, with a roadmap pointing toward 150 million gas per block. Drafts like EIP-7935 and the public “Pump The Gas” campaign outline the path, and a higher limit lets each block hold more operations, which shortens wait times when activity surges. Fusaka supplies the technical foundation for that growth.
Fusaka adds Peer Data Availability Sampling (PeerDAS) and Verkle Trees. With PeerDAS, validators check data availability by requesting small, random samples instead of fetching whole blobs, so each node needs far less bandwidth. Verkle Trees replace Merkle Trees and provide smaller proofs that verify faster, reducing storage needs for light clients.
Developer support has been public, with Eric Connor and Mariano Conti backing the limit raise. The change also lines up with earlier 2025 work under the Pectra upgrade, which readied the client code for these next steps.
Expected impacts and trade-offs
Layer-2 rollups gain room to post bigger transaction batches to mainnet at lower cost. Early reviews expect fee drops of 30–60% and throughput gains of three to five times for some rollups, meaning users and dapps should see cheaper fees.
Validators and node operators face a trade-off as higher limits can raise hardware demands without Fusaka’s fixes. PeerDAS and Verkle Trees counter that pressure by cutting bandwidth and storage requirements so the validator set can stay wide instead of pushing smaller operators out.
Market response mixes hope with caution. Prices have risen on expectations around Fusaka, yet any technical tweak still risks short-term swings. The move to 60 million gas per block widens Ethereum’s immediate throughput and sets the stage for Fusaka on 3 December 2025.
