Ethereum Plans Fusaka Hard Fork for November 2025
2025-07-21
Ethereum is preparing to implement its next major upgrade, known as the Fusaka hard fork, with a tentative release date set for November 2025. The update is expected to introduce several improvements to the Ethereum network, focusing on security, scalability, and overall protocol efficiency.
Following closely behind the Pectra upgrade, which rolled out just six months earlier, Fusaka represents Ethereum’s continued push to enhance user experience and accelerate development.
Developers and the broader Ethereum community have been actively working toward more frequent updates. With Pectra having successfully introduced features such as account abstraction and a higher validator staking limit, Fusaka is set to build on that foundation.
In addition to boosting the network’s resilience, the upcoming hard fork will play a key role in shaping Ethereum’s roadmap through 2026 and beyond.
What to Expect from Fusaka
According to Ethereum core contributors and the ethPandaOps team, the Fusaka hard fork will include 11 Ethereum Improvement Proposals (EIPs).
One of the main proposals, EIP-7825, is designed to make the Ethereum network more secure and better equipped to handle large volumes of transactions.
In preparation for the upgrade, the next developer testnet is expected to go live this week, followed by two public testnets in September and October. These test phases are intended to ensure a stable launch on Ethereum’s mainnet by early November.
Another proposed change is an increase in Ethereum’s gas limit to 150 million, a move aimed at accommodating more transactions per block and reducing congestion.
However, to keep the testing process streamlined, certain proposals, such as EIP-7907, have been removed from the Fusaka release. This particular EIP would have doubled the contract code size limit and introduced new gas metering mechanisms.
Despite these adjustments, Ethereum (ETH) developers remain focused on balancing innovation with network stability.

Developer Challenges and Community Feedback
While the Fusaka upgrade appears to be on track, not all developers are fully confident about the proposed timeline.
Ethereum protocol support member Nixo voiced concerns on social media, suggesting that the deadline could be too tight given the need for client releases and thorough testing.
“If we want to ship by Devconnect, we need our timeline tight,” Nixo posted, referring to the major Ethereum developer event taking place in Buenos Aires from November 17 to 22.
This timeline pressure has led to more conservative planning for the Fusaka hard fork, even as attention is already turning toward future upgrades.
Glamsterdam Upgrade and the Road Ahead
Following Fusaka, Ethereum developers are preparing for another major update, referred to as the Glamsterdam hard fork. While still in the planning stages, its final list of features will be confirmed at the next AllCoreDevs Execution meeting scheduled for August 1.
Some of the proposed features for Glamsterdam could significantly impact the way the Ethereum network operates. One key suggestion from core developer Barnabé Monnot is to reduce block time from 12 seconds to six seconds.
If implemented, this change would make decentralized applications more responsive and improve user experience, particularly for DeFi services.
Vitalik Buterin, Ethereum’s co-founder, also recently shared that approximately 50 percent of validators are in favor of increasing the Layer 1 gas limit to 45 million, which would lower transaction fees and enhance throughput.
While this particular proposal is not tied to Fusaka, it reflects broader support for ongoing improvements to Ethereum’s scalability.
