Ethereum’s upcoming Fusaka upgrade has successfully completed its final test run on the Hoodi testnet, clearing the way for mainnet activation. The trial, launched Tuesday around 18:53 UTC, tested scalability and cost-efficiency improvements through multiple code enhancements.
Hoodi was the last of three testnets — following Holesky and Sepolia — to simulate Fusaka’s operations. The upgrade, coming about six months after Pectra, aims to cut costs for users, developers, and institutions.
Its central innovation, PeerDAS, allows validators to process smaller data portions instead of full “blobs,” easing bandwidth demands and improving performance across Layer 2 networks.
According to the Ethereum Foundation, Fusaka will go live at least 30 days after this final test — tentatively November 28, though core developers may target December 3.
The team is already preparing for Ethereum’s next evolution, Glamsterdam, which will explore proposer-builder separation and other long-term improvements.
