Upgrade Completion

The Ethereum network finalized the Fusaka upgrade with the BPO‑2 fork on Dec 11 2024. This two‑stage enhancement expands data capacity for Layer 2 rollups, aiming to cut their posting costs and lower user fees. Core developers confirmed a smooth activation without disruption.

Technical Changes

Fusaka targets “blobs”, large data packets rollups post to Ethereum. BPO‑1 introduced new protocol rules on Dec 9, while BPO‑2 doubled the target blobs per block from 2 to 4 and the maximum from 6 to 8. The change is backward‑compatible and requires no action from users or most dApp developers.

Immediate Impact

Expanding blob space removes a known bottleneck that drove auction‑style fee spikes. Analysts expect a more stable, predictable fee market for rollup data, continuing the scalability path set by the earlier Dencun upgrade. Early data shows the network remains stable across client implementations.

Benefits for Users

Lower rollup data costs translate into cheaper DeFi swaps, NFT minting, and micro‑transactions in blockchain games. Reduced fees improve the economic security of rollups that rely on Ethereum for data availability. The upgrade reinforces Ethereum’s role as a scalable settlement layer for Web3.
