TechFlow news, September 1 — According to an official blog post, the Ethereum Foundation announced today that the large public testnet Holešky will be shut down within two weeks after the Fusaka upgrade completes. Since its launch in 2023, Holešky has served as Ethereum's largest public testnet and played a critical role in validator operations and protocol upgrade testing.
The Foundation recommends validators and staking service providers migrate to the Hoodi testnet launched in March this year, while application developers may 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 distinct testing needs.
