Ethereum’s Fusaka hard fork activates on final testnet ahead of mainnet launch

Ethereum's upcoming hard fork, named Fusaka, successfully activated on the Hoodi testnet, marking the final testing phase before its mainnet launch, which core developers tentatively scheduled for December 3rd, at least 30 days after the Hoodi deployment. The Fusaka upgrade aims to implement backend improvements for scalability, efficiency, and security, including raising the block gas limit, increasing "blob" capacity, and introducing new node security features. A key component is EIP-7594, which introduces Peer Data Availability Sampling (PeerDAS) to enhance data availability for Layer 2 solutions by allowing validators to survey data segments instead of full blobs. Prior to this, the Ethereum Foundation launched a security audit contest offering up to $2 million for bug discoveries. This upgrade follows the Pectra upgrade six months prior, while discussions for the next major upgrade, Glamsterdam, are already underway.
