Jinse Finance reported that the Ethereum Foundation announced today that the major public testnet Holešky will be shut down within two weeks after the Fusaka upgrade is completed. Since its launch in 2023, this testnet has played an important role as Ethereum's largest public testnet, especially in validator operations and protocol upgrade testing. The Foundation recommends that validators and staking service providers migrate to the Hoodi testnet, which was launched in March this year, while application developers can use the Sepolia testnet for development and testing. After this adjustment, the Ethereum testnet ecosystem will consist of three testnets: Sepolia, Hoodi, and Ephemery, each serving different testing needs.
