Ethereum’s next major network upgrade, called Fusaka, has been scheduled for early November. Developers aim to activate the upgrade on mainnet between November 5 and 12, ahead of the Devconnect event in Buenos Aires. A new developer testnet will go live this week, followed by two public testnets in September and October.
What’s in the Upgrade
Fusaka will include 11 Ethereum Improvement Proposals (EIPs), focusing on network scalability and security. Among them is EIP-7825, aimed at improving Ethereum’s ability to resist attacks while enhancing performance. Another significant proposal, EIP-7594, introduces Peer Data Availability Sampling (PeerDAS), which is expected to help with data-heavy operations such as rollups.

Gas Limit Changes
Developers have proposed raising Ethereum’s gas limit to 150 million to support more complex transactions. Separately, a validator-led proposal suggests increasing the Layer 1 gas limit from 30 million to 45 million. Nearly 50% of validators have signaled support for the latter. Both proposals are intended to boost network capacity, though they may place additional load on smaller validators.
Dropped Proposals
Two proposals originally considered for Fusaka have been removed. EIP-7907, which would have increased the maximum size for smart contract code, was dropped to simplify testing. The Ethereum Object Format (EOF), which aimed to restructure how smart contracts are written and verified, was also excluded due to concerns about complexity and timing.
Looking Ahead: Glamsterdam
Work has already started on the next Ethereum upgrade, Glamsterdam, expected in 2026. One of the proposals under review is a reduction of block times from 12 seconds to 6, which would increase transaction speed. Final decisions on Glamsterdam features are expected during the next AllCoreDevs meeting on August 1.
Next Steps
The success of Fusaka depends on the upcoming testnet phases and final integration checks. Developers are focused on meeting the tight timeline without compromising stability. If testing goes smoothly, Fusaka will mark Ethereum’s latest step toward greater scalability and efficiency.
