What’s new? Ethereum developers have tentatively scheduled the next major hard fork of the protocol, called Fusaka, for November 2025, aimed at improving the efficiency and scalability of the network.

What else is known? The Ethereum community is pushing for more frequent and faster updates to the protocol. According to the timeline, Fusaka will be released six months after the Pectra hard fork.

It introduced account abstraction, allowing wallets to function as smart contracts, increased the validator staking limit from 32 to 2048 ETH, and improved the efficiency of Ethereum-based Layer 2 (L2) networks.

According to the ethPandaOps developer community, Fusaka will be deployed to devnet on July 23, it will include 11 Ethereum Improvement Proposals (EIPs).

Among them is EIP-7825, which aims to make the network more resilient to malicious attacks while scaling. The developers have also proposed increasing the gas limit to 150 million units.

Two public test networks are scheduled to launch in September and October, with a final launch on the mainnet in early November.

Ethereum developers are also preparing to gather feedback on the Glamsterdam hard fork, which will follow Fusaka in 2026. The approval of the list of EIPs it will include will take place on August 1 at the next AllCoreDevs — Execution meeting.

Earlier, Ethereum validators expressed their support for increasing the gas limit to 45 million units to reduce transaction costs and increase the scalability of the network. Ethereum co-founder Vitalik Buterin said that nearly 50% of the staking participants vote in favor of increasing the gas limit in the underlying blockchain.

That said, in early July, Buterin proposed introducing a gas limit for each individual transaction within a blockchain to reduce the risk of DoS attacks.
