Ethereum’s next upgrade, Fusaka, goes live in November ahead of Devconnect
Ethereum’s upcoming Fusaka hard fork is slated for early November 2025, setting the stage for one of the most consequential Ethereum network upgrades in years.
Unlike Pectra, the May 2025 fork that delivered visible changes like account abstraction and higher staking limits, Fusaka operates behind the curtain. It bundles 11 Ethereum Improvement Proposals focused on scalability, node resilience and efficiency, leaving smart contracts untouched.
A devnet launched in July 2025 and a round of Ethereum testnets in September and October will stress‑test the changes before mainnet activation.
Developers aim to ship ahead of the Devconnect conference in Buenos Aires, aligning with Ethereum’s accelerated six‑month upgrade cadence and growing focus on core performance.
Did you know? Fusaka joins a lineage of about a dozen execution‑layer hard forks (from Frontier in 2015 through Pectra in 2025).
Ethereum’s Fusaka hard fork explained
So, what is the Fusaka hard fork? It’s the next Ethereum development milestone, landing only six months after Pectra.
As part of the chain’s 2025 roadmap, Fusaka emphasizes Ethereum scalability updates and node health rather than user-facing features.
The timeline is tight: Devnet‑3 went live in July 2025, public Ethereum testnets follow in September and the mainnet fork is set for Nov. 5, 2025, coordinated to hit a predefined block height.
The choice of date is strategic, aligning with Ethereum community updates around Devconnect. By focusing on protocol refinement, this crypto hard fork lays the groundwork for future proposals like block‑time reduction while maintaining Ethereum’s reputation for steady, iterative progress.
Upcoming Ethereum network upgrades
The Ethereum Fusaka upgrade is about tuning Ethereum’s core engine. The November 2025 Ethereum hard fork bundles 11 infrastructure-level EIPs that refine scalability, improve efficiency and harden the network without breaking existing contracts.
Here’s a breakdown of what’s shipping:
- EIP‑7594 – PeerDAS: A major step in Ethereum scalability updates, this introduces peer data availability sampling so nodes don’t need to download…
