Ethereum's upcoming hard fork, Fusaka, has been successfully deployed on the Hoodi testnet as of October 28, marking the final step before its mainnet activation scheduled for December 3. Previously, Fusaka was implemented on the Holesky and Sepolia testnets. This upgrade includes over 12 Ethereum Improvement Proposals (EIPs), focusing on introducing the Peer Data Availability Sampling (PeerDAS) mechanism, increasing block gas limits, expanding blob capacity, and enhancing node security to improve Ethereum's scalability and data availability.
