Ethereum developers target November rollout for Fusaka upgrade

Ethereum’s network’s next major upgrade, Fusaka, is set for an early November release. According to a July 21 announcement, the upgrade will be rolled out after two public testnets slated for September and October. Developers aim to launch the mainnet ahead of the Devconnect conference, scheduled for November 17–22 in Buenos Aires, Argentina. The Fusaka hard fork will be Ethereum’s first major upgrade since Pectra, which went live earlier this year , introducing account abstraction, increased validator staking limits, and improved layer-2 network efficiency. The upcoming release has been confirmed by multiple Ethereum contributors, including the ethPandaOps community, which noted that the next devnet for Fusaka will go live this Wednesday. It will include 11 Ethereum Improvement Proposals (EIPs). Among the upgrades confirmed so far is EIP-7825, which has been designed to enhance Ethereum’s resilience against malicious attacks while supporting greater scalability. On the other hand, EIP-7907, which would have doubled the contract code size limit, has been removed to avoid delays in testing. Further, Ethereum core developer Tim Beiko has confirmed that the EVM Object Format upgrade will not be included in Fusaka. Developers are expecting to maintain a tight timeline and avoid adding proposals that could risk pushing the release beyond November. What is Fusaka? The Fusaka upgrade is a combined fork, integrating two major upgrades: Fulu for the consensus layer and Osaka for the execution layer. This dual structure introduces foundational changes aligned with Ethereum’s long-term roadmap. One of the core features of Fusaka is PeerDAS (Peer-to-Peer Data Availability Sampling), a system that will reduce the data burden on nodes by allowing them to download smaller portions of rollup data. This is expected to increase data capacity per block and lower transaction fees significantly. The upgrade will also introduce Verkle trees, a more efficient state management structure that replaces the Merkle Patricia Trie. This change will reduce state size, enable stateless clients, and make running a full node more accessible. Together, these upgrades build upon the groundwork laid by the Pectra fork. While Pectra focused on validator enhancements and blob scaling, Fusaka targets scalability through rollup data handling and state optimisation. Setting the stage for the Glamsterdam hard fork Looking beyond Fusaka, Ethereum developers are preparing for the Glamsterdam hard fork, expected in 2026. Discussions around which proposals will be included are ongoing, with final decisions to be announced during the AllCoreDevs Execution meeting on Aug. 1. One of the proposals under consideration for Glamsterdam is reducing Ethereum’s block time from 12 seconds to six seconds. According to Ethereum core developer Barnabé Monnot, this could enhance user experience and improve the performance of DeFi applications.
