Ethereum Core developers have confirmed a tentative timetable for the network’s next big upgrade, Fusaka, during Thursday’s all core developers consensus (ACDC) Ring.
The upgrade, designed to further scale blockchain, is now scheduled for early December with follow -up changes aimed at more than doubling the clutter capacity in the weeks that followed.
Before the fusaka upgrade reaches Ethereum’s mainnet, developers will push the code through three public test networks in October.
If these tests go smoothly, the mainnet activation is targeted to December 3rd. Developers noted that accurate epoch nums and timing will be confirmed in the coming days.
Blob capacity extension via BPO Forks
While Fusaka itself does not immediately change the cluster parameters, the call outlined a phase approach to scaling climbing accessibility through so-called blob parameter (BPO) forks.
One week after the Fusaka BPO-1, the blog target/max raises from 6/9 to 10/15, BPO-2 one week later will push the limit to 14/21.
These step-by-step changes are based on performance observed on Fusaka Devnet-5 and are intended to safely expand capacity without requiring client software updates.
Blobs, introduced in March Dencun upgrade, allows Ethereum to store large amounts of Rollup transaction data more effectively, reducing the cost of LAG-2 scaling network users.
Looking ahead
Ethereum scientist Christine Kim, who reported that the call height points on X noted that additional BPOs remain on the Fusaka timetable, although only the first two were scheduled in this week’s call.
A detailed timeline for the FUSAKA and BPO activations is available through Ethereum’s public notes.
The FUSAKA Escape follows May’s Pectra Upgrade, which introduced changes in validator tackle and new accounts abstraction features, which emphasizes Ethereum’s ongoing push to optimize scalability and network efficiency.
