**[Vitalik Praises Ethereum Fusaka Upgrade]** According to a report by Jinse Finance, the official Ethereum network documentation shows that Ethereum has officially deployed the Fusaka upgrade. This upgrade aims to enhance the network's transaction processing capacity while maintaining existing security standards and decentralization levels. Ethereum co-founder Vitalik Buterin posted on the X platform on Wednesday evening, saying: "A warm congratulations to the Ethereum researchers and core developers who have worked tirelessly over the years to make this achievement possible." The Fusaka upgrade went live on Ethereum's final testnet, Hoodi, in October. Its core is the EIP-7594 proposal—PeerDAS (Peer Data Availability Sampling Protocol). This protocol allows Ethereum nodes to verify data integrity without downloading the full block data, achieving the core goal of "scaling without compromise" (i.e., increasing network capacity while preserving existing security parameters and decentralization characteristics).
