Ethereum core developers have tentatively scheduled the next major hard fork, dubbed Fusaka, for release in November. This upgrade is designed to enhance the network’s efficiency and scalability.
Following Fusaka, the next planned upgrade—Glamsterdam—is expected to have its feature set finalized on August 1.
The Ethereum community has been advocating for quicker and more frequent protocol upgrades. If the timeline holds, Fusaka will arrive roughly six months after the Pectra hard fork, which introduced account abstraction, raised the validator staking limit, and optimized layer-2 network performance.
According to ethPandaOps, a community group focused on Ethereum development, Fusaka’s next devnet is set to launch Wednesday and will include 11 Ethereum Improvement Proposals (EIPs). Among them is EIP-7825, which aims to improve the network’s resilience against malicious attacks while also supporting scalability.
Developers have also proposed increasing the gas limit to 150 million to accommodate growing network demands.
To streamline testing, however, EIP-7907—which proposed doubling the contract code size limit and adding gas metering—has been removed from the upgrade.
In April, Ethereum core developer Tim Beiko confirmed that the controversial EVM Object Format (EOF) upgrade will not be included in the Fusaka hard fork.
Ahead of Fusaka’s expected launch in early November, two public testnets are scheduled for rollout in September and October.
In a post on X, Ethereum protocol support member Nixo voiced concerns about the feasibility of launching the Fusaka hard fork on mainnet this year.
“If we want to ship by Devconnect, we need our timeline TIGHT. We’ll go over that in detail. Can we get client releases in the ~next month & a half?” Nixo wrote.
Devconnect is scheduled to take place from November 17 to 22 in Buenos Aires, Argentina.
The tentative deadline for Fusaka coincides with preparations by Ethereum core developers to finalize upgrade features for the following hard fork, Glamsterdam.
The list of upgrades set to be included in Glamsterdam will be announced during the next AllCoreDevs – Execution meeting on August 1.
Recent proposed upgrades
Ethereum core developer Barnabé Monnot has proposed reducing the network’s block time from the current 12 seconds to six seconds—a change he believes would significantly enhance user experience and improve the efficiency of DeFi applications.
If approved, the upgrade is expected to be included in the Glamsterdam hard fork, which is tentatively scheduled for release in 2026.
In the meantime, Ethereum validators have expressed support for raising the network’s gas limit to 45 million, a move aimed at lowering transaction costs and boosting scalability.
In a post on X this Sunday, Ethereum co-founder Vitalik Buterin noted, “Almost exactly 50% of stake is voting to increase the L1 gas limit to 45m.”
