The next major upgrade of Ethereum, "Fusaka", is scheduled to go live on December 3.

On October 31, researchers from the Ethereum Foundation officially set a date for its Mainnet Hard Fork (code-named “Fusaka”). During Thursday's “All Core Developers” call, researchers from the Ethereum Foundation stated that Fusaka will go live on December 3. Developers have been targeting this date since at least mid-September. Fusaka was launched on the Hoodi Testnet this past Tuesday, marking the final step toward Mainnet activation. Earlier this month, it was successfully deployed on the Holesky and Sepolia Testnets. This backward compatible Fusaka hard fork will implement around a dozen Ethereum Improvement Proposals to enhance the sustainability, security, and scalability of the base chain and its surrounding Layer 2 ecosystem. Notably, Fusaka will implement “Peer Data Availability Sampling” (PeerDAS), a technique that simplifies validator access to data. PeerDAS was initially planned for implementation during a major upgrade to Ethereum (i.e., Pectra in February), but was postponed for testing. Fusaka will also increase Ethereum's block fuel limit from 30 million units to 150 million units, and it is expected to rapidly double the data block capacity.
