Ethereum Developers Plan Fusaka Upgrade for December, Blob Capacity Increases
Ethereum developers have set a tentative roadmap for the upcoming major upgrade, Fusaka, targeting early December for implementation. The upgrade aims to enhance the blockchain's scalability and follows a series of tests on three public networks in October. If successful, mainnet activation is expected by December 3, with exact timing details forthcoming.
Blob Capacity Expansion
- The Fusaka upgrade will not immediately change blob parameters but will initiate a phased scaling via Blob Parameter Only (BPO) forks.
- BPO-1, scheduled one week post-Fusaka, will increase blob target/max from 6/9 to 10/15.
- BPO-2, following another week later, will push limits to 14/21.
- These changes aim to expand capacity based on Fusaka Devnet-5 performance without needing client-side updates.
- Blobs, introduced in the Dencun upgrade, help store rollup transaction data efficiently, reducing costs for layer-2 network users.
Further BPOs are planned, although only the first two were scheduled in the latest call. A detailed timeline is available through Ethereum’s public notes.
This rollout continues Ethereum's efforts to optimize scalability and efficiency, building on May's Pectra upgrade, which modified validator staking and introduced new account abstraction features.
