Ethereum developers have officially signed off on the long-awaited Fusaka upgrade for December 3, following a decision made during the network’s bi-weekly coordination call on Thursday.
The move starts the countdown to the second Ethereum hard fork of 2025.
The main feature of the Fusaka upgrade is PeerDAS, one of 12 improvements included in the release. PeerDAS allows validators to verify only parts of data, rather than entire “blobs,” significantly reducing bandwidth requirements and costs for validators and Layer 2 networks. This will make Ethereum faster and cheaper, both for users transacting and for developers relying on the network.
The decision was finalized in All Core Developers Consensus Layer (ACDC) Call #168, just two days after the upgrade was successfully deployed to Hoodi, the third and final testnet, without any issues.
The upgrade will activate on the Ethereum mainnet when the blockchain reaches location 13,164,544, which is expected to occur at 9:49 p.m. UTC on December 3.
“Let’s go ahead and do this,” said Alex Stokes, a researcher at the Ethereum Foundation who is leading the ACDC calls. “It’s been a big effort to put this all together at this point, so thank you for that. It’s a really cool bracket.”
