Ethereum to Sunset ‘Holesky’ Testnet in September
The plan comes after the testnet fell offline due to a faulty test for Pectra.
Ethereum’s largest testnet, Holesky, will shut down in September due to validator issues, replaced by the newly launched Hoodi network.
What’s the Scoop?
- Testnet Closure:
Ethereum will discontinue its largest test network, Holesky, following challenges with the upcoming Pectra upgrade. - New Testnet Replacement: Hoodi, a newly launched test network, will replace Holesky and facilitate upgrades like Pectra.
- Validator Issues: Inactivity leaks in Holesky caused significant congestion, making it unsuitable for validator lifecycle testing.
- Timeline: Holesky will begin winding down operations immediately, with full deprecation set for September 30.
