Goerli (Goerlitzer Testnet)

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

⚠️ Goerli will be deprecated as of January 2023. It will be supported long term for another 12 months. 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.
