The --goerli cross-client proof-of-authority testnet configuration.

• Website: https://goerli.net

⚠️ Goerli will be deprecated as of January 2023. It will be supported long term for the longer of three months after the Dencun upgrade is activated on it, or one month after Dencun is activated on the Ethereum mainnet. No further network upgrade will be deployed to the network after this. Please consider using Sepolia moving forward.

To learn more about post-merge testnets check out the Ethereum website or this Devcon 6 talk.

Goerli Testnet was the first proof-of-authority cross-client testnet, synching Geth, Nethermind, Hyperledger Besu, and others. This testnet was a community-based project and completely open-source. It was born in September 2018 during ETHBerlin and has been growing in contributors ever since.

The Goerli testnet was merged with the Prater proof-of-stake beacon chain. This marked the end of the permissioned proof-of-authority phase and everyone is now able to run a validator for Goerli. Therefore, this repository contains both Goerli execution-layer and Prater consensus-layer configurations.
