Ethereum’s core developers have announced that the network’s next major update, Fusaka, is planned to be deployed on the mainnet on December 3. This date was revealed during the ACDC #165 developer meeting. Activation on the Holesky test network is scheduled for October 1, on Sepolia for October 14, and on Hoodi for October 28, ahead of the mainnet rollout. The specific date, time, and epoch numbers will be clarified in the coming days.
Key Features of the Fusaka Update
Fusaka will support Ethereum’s scalability and security goals. One of the standout features of the update is Peer Data Availability Sampling, which allows validators to verify large datasets known as “blobs” in smaller parts rather than downloading them entirely. Developers note that this method will enhance transaction efficiency and reduce network load. Additionally, the blob capacity is expected to double within two weeks following the update.

The current limit of 30 million units will be raised to 150 million units, allowing for more transactions to be added to the blocks. The storage of data will be optimized through the Verkle Trees structure, and proof sizes will be reduced. Performance adjustments made to the EVM will also contribute to faster operation of smart contracts.
Pre-Update Security Initiatives
The Ethereum Foundation has initiated a security-focused process before Fusaka. A security competition lasting four weeks will offer researchers up to $2 million for finding bugs before the update reaches the mainnet. The competition aims to identify potential security vulnerabilities in advance.
Following Fusaka, Ethereum’s roadmap includes the Glamsterdam update. Scheduled for 2026, this update is expected to introduce developments like the EVM Object Format (EOF) and faster block times. All these updates aim to further enhance the capacity and transaction speed of the Ethereum network.
