Become an Ethereum 2.0 Validator*

* Testnet validator


The lighthouse testnet is currently down. We expect to bring it up again in late-January or early-February. Thanks to all who participated in the testnet, we look forward to having your input again in the future.

Running Lighthouse validator is easy if you're familiar with the terminal. It runs on Linux, MacOS and Windows and we have a Docker work-flow.

Before you start, you'll need Metamask and 3.2 gETH (Goerli ETH). We recommend the mudit.blog faucet for those familiar with Goerli, or goerli.net for an overview of the testnet.

1. Install and start Lighthouse

There are two, different ways to install and start a Lighthouse validator:

Once you have completed only one of these steps, move onto the next step.

2. Submit your deposit to Goerli

This deposit is using gETH (Goerli ETH) which has no real value. Don't ever send real ETH to our deposit contract!

3. Leave Lighthouse running

Leave your beacon node and validator client running and you'll see logs as the beacon node keeps synced with the network and the validator client produces blocks and attestations.

It will take 4-8+ hours for the beacon chain to process and activate your validator, however you'll know you're active when the validator client starts successfully publishing attestations each slot:

Dec 03 08:49:40.053 INFO Successfully published attestation      slot: 98, committee_index: 0, head_block: 0xa208…7fd5,

Although you'll produce an attestation each slot, it's less common to produce a block. Watch for the block production logs too:

Dec 03 08:49:36.225 INFO Successfully published block            slot: 98, attestations: 2, deposits: 0, service: block

If you see any ERRO (error) logs, please reach out on Discord or create an issue.

Happy staking!
