Installing the beacon chain and validator

The easiest way to install the beacon chain and validator is by running the prysm.sh script found in the main directory of the Prysm repository. This script will download and start up the latest release of Prysm binaries compatible with the host system.

Prysm Basic Setup

Running the Prysm startup script

  1. Create a working directory and enter it:
mkdir prysm && cd prysm
  1. Fetch the prysm.sh script from Github and make it executable:
curl https://raw.githubusercontent.com/prysmaticlabs/prysm/master/prysm.sh --output prysm.sh && chmod +x prysm.sh
  1. Run the prysm.sh script alongside any startup parameters:
./prysm.sh beacon-chain

Not getting enough peers? Refer to the improve P2P connectivity section of this documentation for tips on network configuration.

The prysm.sh script will now download and initialise the beacon chain with the specified parameters. The terminal will produce output like so:

./prysm.sh beacon-chain
Latest Prysm version is v0.3.3.

Starting Prysm beacon-chain
...

At this point, the beacon chain data will begin synchronising up to the latest head block. Please note that, depending on your network capacity and CPU, this process may take several hours. Once it is complete, you will be ready to make a deposit and begin setting up a validator client.

NOTICE: The beacon node you are using should be completely synced before submitting your deposit for the validator client, otherwise the validator will not be able to validate and will inflict minor inactivity balance penalties.

Staking ETH: Running a validator client

For step-by-step assistance with performing a deposit and setting up a validator client, see the activating a validator section of this documentation.

Once your beacon node is up, the chain will be waiting for you to deposit 32 Goerli ETH into a validator deposit contract in order to activate your validator (discussed in the section below).

If you need Goerli ETH, follow the instructions found on prylabs.network to use the testnet faucet. Otherwise, you can contact a team member on Discord to be sent some.

Please note that it may take up to 12 hours for the nodes in the network to process a deposit. Once the node is active, the validator will immediately begin performing its responsibilities.

In your validator client, you will be able to frequently see your validator balance as it goes up over time. Note that, should your node ever go offline for a long period, a validator will start gradually losing its deposit until it is removed from the network entirely.

Congratulations! If you've made it this far, you are now running Ethereum 2.0 Phase 0.
