After Fusaka activates, Ethereum intends to implement “Blob Parameter Only” (BPO) forks. These forks will incrementally raise the per-block blob target and maximum, measured in steps. This method enhances data capacity while avoiding node overload, leveraging the new sampling design.
Furthermore, developers have also started early coordination for the subsequent “Glamsterdam” upgrade. Roadmap items under discussion include enshrined proposer-builder separation (ePBS) and block-level access lists, with a rough 2026 window. Planning continues while teams prioritize a stable rollout of the Fusaka upgrade and Ethereum price increase methods.
“Once all three testnets have successfully upgraded, a mainnet activation slot will be chosen,” the Ethereum Foundation’s protocol coordination team wrote in its testnet announcement.
