TechFlow, on October 29, according to Theblock, Ethereum's next hard fork, Fusaka, went live on the Hoodi testnet on Tuesday, marking the final step before mainnet activation, expected by year-end.
Hoodi is the third and final testnet deployment, following activations on Holesky and Sepolia testnets earlier this month. The Ethereum Foundation previously stated that Fusaka mainnet launch would occur at least 30 days after Hoodi testnet deployment, with core developers tentatively targeting December 3 for the hard fork.
Fusaka aims to deliver backend improvements to enhance scalability, efficiency, and security of the largest smart contract blockchain, including increasing block gas limits, expanding "data blob" capacity, and introducing new node security features. The upgrade includes at least a dozen Ethereum Improvement Proposals (EIPs), most notably EIP-7594, which introduces Peer Data Availability Sampling (PeerDAS), enabling validators to sample data segments instead of entire "data blobs," thereby improving data availability for Ethereum's Layer 2 ecosystem.
