Golden Finance reports that the next Ethereum hard fork, Fusaka, was successfully activated on the Hoodi testnet on Tuesday. This is the final step following the Holesky and Sepolia testnets earlier this month. Fusaka is planned to undergo at least 30 days of testing before its mainnet launch, with core developers tentatively scheduling the launch for December 3. This upgrade will enhance Ethereum's scalability, efficiency, and security, including increasing block gas limits, expanding "Blob" capacity, and introducing new node security features. The upgrade includes several Ethereum Improvement Proposals (EIPs), among which EIP-7594 introduces PeerDAS technology, allowing validators to sample data fragments instead of complete Blobs, optimizing Layer 2 data availability. The Ethereum Foundation has also launched a four-week security audit competition with a prize pool of up to $2 million. The Fusaka hard fork is about six months after Ethereum's last major upgrade, Pectra, and developers have already begun planning the next upgrade, Glamsterdam.
