[Ethereum Completes Fusaka Upgrade, Officially Enters Twice-Yearly Hard Fork Rhythm] According to Golden Finance, Ethereum's 17th major upgrade, 'Fusaka,' was officially activated on the mainnet at epoch 411392 (around 5:50 AM Beijing time on Thursday), approximately seven months after the Pectra upgrade in May. This upgrade not only brings multiple UX and scalability improvements but also marks Ethereum's official entry into an accelerated development rhythm of 'twice-yearly hard forks.' Consensys stated that Ethereum researchers will aim for two upgrades per year in the future. Since the 2022 Merge, Ethereum has typically conducted only one major update per year, including Shapella (2023), Dencun (2024), and Pectra (2025). Fusaka introduces several key technical changes, including a new sampling technology, 'PeerDAS,' which impacts data availability and pricing. This upgrade includes a total of 9 core EIPs and 4 supplementary EIPs, making it, by certain metrics, one of the largest upgrades in Ethereum's history.
