The final dress rehearsal for Ethereum’s upcoming Fusaka upgrade occurred on Tuesday, as the blockchain prepares for the mainnet hard-fork activation.
The test, which went live around 18:53 UTC on the Hoodi testnet, involved approving a series of code changes aimed at making Ethereum more scalable and profitable.
Testnets are replicas of a blockchain’s mainnet and provide developers with a secure environment to test important updates and fix any issues before they go live on the mainnet.
Hoodi was the last of three test networks to run a Fusaka simulation, with two other successful test updates on the Holesky and Sepolia networks.
Roughly six months after Ethereum’s Pectra upgrade, Fusaka introduces changes designed to reduce costs for developers, users, and institutions running the network. Its centerpiece, PeerDAS, allows validators to verify only segments of data rather than entire “blobs,” alleviating bandwidth demands and reducing expenses for both validators and Layer 2 networks.
Once the three tests are done, the developers will finalize the date when Fusaka will be available on the mainnet. According to the Ethereum Foundation, it will be at least 30 days after today’s test, tentatively putting it on November 28 at the earliest, although core developers on a bi-weekly call last week discussed the possibility of it going live on the mainnet on December 3.
Ethereum developers are already moving full steam ahead on the next hard fork, known as Glamsterdam. While nothing is set in stone yet, developers plan to include proposals that work on the separation between proponent and builder.
