The testnet is publicly accessible and NOT a simulation. We provide a cloud cluster of nodes that participate in consensus, but anyone can join the network and contribute.
The testnet is a single client 'Prysm network'. Unlike Ethereum 1.0, which has Geth and Parity, this network is entirely Prysm-only.
Staking of Goerli test ETH is included in the network. Users can utilise the deposit contract, run a validator client, and participate in consensus to earn rewards or penalties.
Features LibP2P by Protocol Labs for decentralised, peer-to-peer networking of nodes.
Implements v0.9.3 of the official beacon chain specification created by the Ethereum Research team (the latest version is v0.9.4).
The testnet is using the ETH2 mainnet configuration, with the only change being validators deposit 3.2 ETH, instead of 32 ETH.
This is NOT a multi-client network, though this is the next step most ETH2 teams have in mind.
The testnet uses different configuration parameters than what we’d see on mainnet; that is, we support fewer shards, a smaller validator count, and different constants for the sake of simplicity.
The testnet does not contain voluntary exits or attester/proposer slashings, as those will come in later iterations and are not critical for showcasing the core functions of the beacon chain.
