Ethereum is getting serious this time—The Fusaka hard fork is officially live, integrating the previously separate Osaka and Fulu proposals into one. This marks the first full implementation of Ethereum's "Protocol" strategy.

The main updates all target scalability: PeerDAS and BPO enable dynamic expansion of blob data, the L1 gas limit is directly raised to 60 million, and the baseline for blob fees has also been adjusted. These combined measures directly benefit Layer 2s the most—their transaction fee pressure will be significantly reduced going forward.

In short, this upgrade is paving the way for scaling the entire Ethereum ecosystem, especially for those Layer 2 networks that rely on data availability, making their future much smoother.
