Ethereum developers officially signed off on the long-awaited Fusaka upgrade for December 3, following a decision made during the network’s biweekly coordination call on Thursday.
The move starts the countdown to Ethereum’s second hard fork in 2025.
The main feature of the Fusaka update is PeerDAS, one of 12 improvements included in the release. PeerDAS allows validators to verify only parts of data, rather than entire “blobs”, which significantly reduces bandwidth requirements and reduces costs for both validators and Layer 2 networks. This will make Ethereum faster and cheaper, both for users transacting and for developers building on the network.
The decision was made during the 168th All Core Developers Consensus Layer (ACDC) call, just two days after the update was successfully deployed to Hoodi, the third and final testnet, without any issues.
The upgrade will go live on the Ethereum mainnet when the blockchain reaches slot 13,164,544, which is expected to occur at 21:49 UTC on December 3.
“Let’s go ahead and do this,” said Alex Stokes, a researcher at the Ethereum Foundation who leads the ACDC calls. “It was a big boost to be able to accomplish this at this time, so thank you for that. This is a really cool fork.”
