The --goerli and --kotti cross-client proof-of-authority testnet configurations.

• https://goerli.net

There are many Ethereum testnets available for experimenting with smart contracts and deploying decentralised applications before going live on the main Ethereum network. However, there is no testnet available that is both widely usable across all client implementations, and robust enough to guarantee consistent availability and high reliability. This is what Görli tries to be for Ethereum and Kotti for Ethereum Classic. Read more on the motivation in the Testnet Proposal.

All clients supporting the Clique engine (EIP-225) are able to sync with Görli or Kotti.

You can connect Geth to Görli by executing geth --goerli. go-ethereum/#18121

You can connect Multi-Geth to Kotti by executing geth --kotti. multi-geth/#17

Connect to Görli using the Clique engine: parity --chain goerli parity-ethereum#9981

Connect to Kotti using the Clique engine: parity --chain kotti parity-ethereum#9981

Connect to Görli using Hyperledger Besu by executing besu --network=goerli. pantheon/#717

Connect to Görli by using the provided goerli.cfg included in Nethermind 0.9.1: nethermind/#234

dotnet run --config configs/goerli.cfg

Connect to Görli by using the provided state and genesis included in EthereumJS 0.6.1: ethereumjs-common/#31
