Ethereum developers launched the second test of the upcoming Fusaka upgrade early Tuesday morning at the Sepolia network, marking another step towards the upgrade’s main debut.
The test follows a successful roll -out on Holeky test network two weeks ago. Developers are planning a last general test on the HOODEnet on October 28, after which they set a date to activate Fusaka at Ethereum’s most important blockchain.
If only a few months after Ethereum’s largest pectra upgrade, Fusaka is designed to lower the cost of institutions using the network. One of its key features, Peerdas, allows validators to verify only parts of data rather than the whole “clatter.” This improvement reduces bandwidth requirements and helps reduce costs for both LAG-2 networks and validators.
Testnets like Sepolia play a crucial role in Ethereum’s development cycle, giving developers a reliable environment for testing upgrades under conditions in the real world before going live on the main network.
However, Holeky has begun to show signs of aging and is expected to be discharged soon. Its successor, Hood, launched earlier this year, is designed to mirror Ethereum’s mainnet. The upcoming Hood test is expected to be the most narrative indicator yet about how Fusaka will work when it goes live.
