Ethereum Launches Holesky, Its Largest Testnet Yet, To Replace Goerli and Boost Testing Capabilities

Ethereum is releasing a new testnet called Holesky to enhance testing capabilities for the ecosystem.
Holesky aims to be bigger than Ethereum's mainnet with over 1.4 million validators to allow more rigorous testing.
Goerli, Ethereum's largest existing testnet, will be phased out and replaced by Holesky.
Goerli has faced issues like capped token supply that have limited its ability to meet demand as Ethereum's developer community grew.
Holesky's launch on the one year anniversary of the Mergeupgrade is meant to attract validators and jumpstart activity on the new testnet.
