BlockBeats News, October 31st, Ethereum Foundation researchers have officially set a date for the mainnet hard fork (codenamed "Fusaka"). During Thursday's "All Core Developers" call, Ethereum Foundation researchers announced that Fusaka will go live on December 3rd.

Developers have targeted this date since at least mid-September. Fusaka went live on the Hoodi testnet earlier this week, marking the final step towards mainnet activation. Earlier this month, it was successfully deployed on the Holesky and Sepolia testnets.

This backwards-compatible Fusaka hard fork will implement around a dozen Ethereum Improvement Proposals to enhance the base chain and its surrounding layer 2 ecosystem's sustainability, security, and scalability. Of particular note, Fusaka will introduce "Peer Data Availability Sampling" (PeerDAS), a technology to simplify validator access to data. PeerDAS was initially planned for a major Ethereum upgrade (Pectra in February) but was delayed for testing. Fusaka will also increase Ethereum's block gas limit from 30 million units to 150 million units, expecting to rapidly double block capacity.
