Ethereum devs officially target Dec. 3 for Fusaka upgrade

Two days after pushing out the final testnet deployment of Ethereum's next major upgrade, Ethereum Foundation researchers have officially set a date for the mainnet hard fork, dubbed Fusaka.

In an All Core Devs call on Thursday, EF researchers said Dec. 3 will be the go-live date for Fusaka. The developers had tentatively targeted this date since at least mid-September.

Fusaka went live on the Hoodi testnet on Tuesday in its final step towards mainnet activation following successful deployments on the Holesky and Sepolia testnets earlier this month.

The backward-compatible Fusaka hard fork will implement about a dozen Ethereum Improvement Proposals to improve the sustainability, security, and scalability of the basechain and surrounding Layer 2 ecosystem.

Most notably, Fusaka will implement Peer Data Availability Sampling (PeerDAS), a streamlined technique for validators to access data. PeerDAS was initially slated for Ethereum's last major upgrade, Pectra, in February, but was delayed due to the need for testing.

Fusaka will also boost Ethereum's block gas limit from 30 million to 150 million units and is expected to rapidly double blob capacity.

Last month, the non-profit Ethereum Foundation launched a four-week audit contest for Fusaka, offering up to $2 million in rewards for security researchers who uncover bugs before the hard fork reaches mainnet.
