The Ethereum core developers have set the date for the Fusaka hard fork, a major update that would improve the blockchain’s security and scalability, for November 2025. Fusaka wants to make Ethereum’s speed even better to keep up with the growing demands of the network after the Pectra upgrade, which added account abstraction and raised the limitations on validator staking.
This upgrade, which includes 11 Ethereum Improvement Proposals (EIPs), shows how the community wants Ethereum to stay at the top of the blockchain space by getting regular, important updates.
The goal of the Fusaka upgrade is to make the network better by making strategic improvements. EIP-7825 is a great proposal that makes Ethereum more resistant to attacks and speeds up transactions. Other EIPs focus on managing blobs and making gas use more efficient. They build on the Dencun upgrade, which added data blobs to make layer-2 scalability possible.
Developers have also suggested raising the gas limit to 150 million. This might make Ethereum easier for users and developers to utilize by lowering transaction fees and reducing network congestion.
Developers left out EIP-7907, which suggested increasing the contract code size limit and adding gas metering to make the upgrade process easier.
This choice, made during the 216th Ethereum Execution Layer Core Developer Meeting, puts stability first and lowers the risks to the timeline. Ethereum will have a smooth transition to Fusaka by keeping the present constraints on the size of smart contracts. EIP-7907 will be put off until the Glamsterdam hard fork in 2026.
The timescale for the Fusaka upgrade is ambitious. The devnet will open on July 23, 2025, and public testnets will follow in September and October. These testnets will let developers and the community thoroughly test the 11 EIPs to make sure they are strong before the mainnet deployment.
Nixo, a member of the Ethereum protocol support group, said that a “tight” timeline is needed to fulfill the November deadline. This is especially true since Devconnect, an event for getting feedback from the community, is slated for November 17-22 in Buenos Aires.
The Ethereum community’s promise to make regular updates shows that the needs of its users and the cryptocurrency market as a whole are expanding.
The suggested gas limit increase to 150 million might enhance transaction capacity by more than 11%, which would make layer-2 solutions like Arbitrum and Optimism work better. The market is still cautious, and Ethereum is trading at $2,484.74. However, if the Fusaka launch goes well, it might make people more positive, which could push ETH prices up towards $4,000.
The Glamsterdam hard fork in 2026 will build on these enhancements after Fusaka and the feature confirmations are planned in August 2025. The Ethereum Foundation and developers are still committed to making improvements that strike a balance between innovation and reliability.
