TLDR:
- Fusaka is live on Ethereum’s Hoodi network, preparing for a December 3 mainnet activation.
- The upgrade includes EIPs 7594, 7825, and 7935 to improve scalability and lower costs.
- Nethermind confirmed the Hoodi fork completed successfully, ensuring network readiness for Fusaka.
- Blob capacity upgrades in December and January will expand rollup data throughput.
Ethereum’s next major upgrade has begun its final approach. The Fusaka rollout started on the Hoodi network, setting the stage for a December 3 mainnet activation.
Developers described the move as a step toward improved scalability, reduced costs, and stronger security. The rollout will progress in stages through early 2026, marking a critical chapter in Ethereum’s long-term scaling roadmap.
The update introduces a wave of new Ethereum Improvement Proposals (EIPs) designed to boost performance across the network. It also lays the foundation for parallel execution, a feature expected to enhance throughput and efficiency across Layer 2 ecosystems.
Fusaka Introduces Core EIPs to Boost Ethereum Performance
According to Consensys, the Fusaka upgrade delivers a suite of EIPs aimed at improving both speed and scalability. Among them is PeerDAS (EIP-7594), which targets higher Layer 2 throughput while keeping node requirements manageable.
The package also includes EIP-7825 and EIP-7935, two proposals that adjust gas limits and prepare the system for parallel execution. Both are expected to improve network efficiency once Fusaka activates on the mainnet.
Ethereum’s next major upgrade, Fusaka, is now live on the Hoodi network!
Fusaka mainnet activation is scheduled for December 3rd.

Further updates like CLZ (EIP-7939) and secp256r1 (EIP-7951) are designed to boost zero-knowledge proving performance and enhance security features. These changes align with Ethereum’s broader goal of supporting the next phase of rollup scaling while keeping infrastructure decentralized and accessible.
Consensys confirmed that client operators will have a 30-day window to upgrade before activation. The client release window opens on November 3, ensuring ample preparation time ahead of the mainnet deployment.
Hoodi Fork Completes as Ethereum Teams Align for Launch
The Nethermind team reported that the Hoodi fork has completed successfully and is now running smoothly on its client. This marks another clean upgrade in Ethereum’s testing sequence and a key milestone toward Fusaka’s full release.
In a post on X (formerly Twitter), Nethermind credited developers, researchers, and node operators for ensuring a seamless transition. The completion of Hoodi signals that core client teams are aligned and that the network is stable for upcoming changes.

Following the mainnet launch on December 3, Ethereum will proceed with two more Fusaka milestones. The first, on December 17, will increase blob capacity to improve data handling for rollups. A second hard fork on January 7, 2026, will extend that capacity even further, pushing Ethereum closer to its long-term scalability vision known as the “Surge.”
With Fusaka in motion, ETH continues to advance toward a future where Layer 2 solutions and parallel processing redefine network efficiency and cost structures.
