Ethereum’s Holešky Testnet to Shutter Following Fusaka Upgrade

The Ethereum Foundation will decommission the Holešky testnet following the Fusaka upgrade, marking a shift toward its Hoodi successor. This decision comes after challenges in operating Holešky prompted a transition to the more robust Hoodi testnet, which offers improved functionality for validator testing. The change primarily impacts testing procedures but not mainnet operations. The foundation’s move reflects improvements based on the Pectra upgrade and aims to address inefficiencies that occurred during the previous testnet phase.
