Ethereum (ETH) is planning to introduce the latest upgrade, known as the Fusaka upgrade, on December 3, 2025. This is a timeline accelerated from previous expectations for a 2026 launch. this announcement It comes from Christine Kim, a researcher who monitors advances in Ethereum’s development.
Checking the activation date for the mainnet was made in all recent Core Developer Consensus (ACDC) calls. There, developers established a schedule of public testnet upgrades and a Blob-Parameter Only (BPO) hard fork associated with fusion.
Fusaka Ethereum Update
Developers are surprisingly easy to reach consensus on these issues, showing a smooth path to moving forward despite ongoing testing challenges. They continue to commit to activation day in December, except for a major setback during the next few months of testing.
Currently, two versions Face Debet It’s working. The devnet-3 is stable and the client team is proactively dealing with software fixes. Meanwhile, DevNet-5 is stable, but there were issues earlier this week, including bugs on multiple clients and misunderstandings on nodes.
These issues are reportedly limited the team’s ability to collect important data on Blob-Parameter Only (BPO) values. However, insights still derive from a short period of DevNet-5 stability, leading to recommendations for setting the maximum blob count for future hard forks.
The Ethereum Foundation’s Ethpandaops team plans to roll out Fusaka Devnet-6 in the coming weeks to verify the findings of Devnet-5.
The team is focused on addressing the Price Client bug that appeared in devnet-5. High blob count It becomes an orphan block. Additionally, a recent update to the “CKZG” library resolves previous issues and newer versions are now available on GitHub.
Future test net
The Fusaka Rollout timeline is well defined, with several key upgrades scheduled before the mainnet is activated. Future testnets include the Holesky upgrade on October 1st, the Sepolia upgrade on October 14th, and the Hoodi upgrade on October 28th.
The developer agreed that the client team needs to integrate these releases Testnet upgrade However, you can publish individual updates that are similar to mainnet activations.
In independent but related developments, the Ethereum community is engaged in discussions regarding the naming of a new consensus layer upgrade called Gram Stardom.
This includes denunciation of Sepolia’s testnet, but the developers have ensured that the community has enough time to adapt to this change as a new testnet is set to be launched in March 2026.
At the time of writing, Ethereum traded at $4.460, recording a 3.5% price decline over the 24-hour time frame. Still, Altcoin will register an 80% profit from the start of the year.
