ETHEREUM'S FUSAKA UPGRADE EXPLAINED

Summary from the TLDR Crypto newsletter

Fusaka will ramp Ethereum's data availability capacity to 48 blobs per block via PeerDAS and BPO hardforks, building on EIP-4844's blob transactions and Pectra's doubled blob target. Base engineers teamed up with OP Labs, Test in Prod, and Soneium to unblock PeerDAS, optimize client implementations, and validate scaling through devnet tests. Their work, spanning spec authorship, performance improvements, and expanded test coverage, accelerates higher-throughput rollups by enabling beacon nodes to sample blob data rather than ingest it all. This L2–L1 collaboration invites more developers to join working groups and contribute to Fusaka and future Ethereum upgrades.
