Ethereum Activates Fusaka Upgrade, Aiming to Cut Node Costs, Speed Layer-2 Settlements

Ethereum successfully activated its "Fusaka" upgrade on Wednesday, a major code change combining consensus and execution layer hard forks (Fulu + Osaka). The core feature is PeerDAS, which allows validators to check only small slices of data blobs instead of the entire data, significantly reducing computational load and costs for validators and Layer-2 networks settling on Ethereum. This is expected to speed up verification, reduce gas fees, and lower the barrier for smaller validator operators, although large institutions may see fewer savings initially. Developers prioritized PeerDAS to ensure the upgrade shipped quickly, demonstrating Ethereum's commitment to speed and efficiency, which has also drawn positive attention from institutions like Fidelity Digital Assets. The upgrade also included 12 other Ethereum Improvement Proposals (EIPs) focused on protocol cleanup, transaction limits, and developer experience, while developers are already looking ahead to the next upgrade, Glamsterdam.
