Ethereum's latest upgrade, Fusaka, initiates a new schedule for hard forks, aiming for two major updates each year. The upgrade introduces significant changes, including PeerDAS for improved data sampling and enhancements to transaction costs and scalability. Fusaka marks a shift in Ethereum's development pace following the Merge.

Ethereum has raised its block gas limit to 60 million as it prepares for the Fusaka upgrade. This change is attributed to improvements in block-size safeguards, client optimizations, and successful testnet results. The upgrade is set to enhance network efficiency and transaction throughput.

Vitalik Buterin highlights the significance of the PeerDAS feature in Ethereum's Fusaka upgrade, which allows nodes to verify block data without storing it entirely, enhancing scalability. He notes that while the initial rollout will be conservative, PeerDAS is essential for future Layer 1 and Layer 2 scaling, potentially allowing for more efficient data handling and reduced strain on the network.
