# Become an Ethereum 2.0 Testnet Validator
|
|
|
|
Running a Lighthouse validator is easy if you're familiar with the terminal.
|
|
|
|
Lighthouse runs on Linux, MacOS and Windows and has a Docker work-flow to make things as simple as possible.
|
|
|
|
|
|
## 0. Acquire Goerli ETH
|
|
Before you install Lighthouse, you'll need [Metamask](https://metamask.io/) and 3.2 gETH
|
|
(Goerli ETH). We recommend the [mudit.blog
|
|
faucet](https://faucet.goerli.mudit.blog/) for those familiar with Goerli, or
|
|
[goerli.net](https://goerli.net/) for an overview of the testnet.
|
|
|
|
> If this is your first time using Metamask and/or interacting with an ethereum test network, we recommend going through the beginning of [this guide](https://hack.aragon.org/docs/guides-use-metamask) first (up to the *Signing your first transaction with MetaMask* section).
|
|
|
|
## 1. Install and start Lighthouse
|
|
|
|
There are two, different ways to install and start a Lighthouse validator:
|
|
|
|
1. [Using `docker-compose`](./become-a-validator-docker.md): this is the easiest method.
|
|
|
|
2. [Building from source](./become-a-validator-source.md): this is a little more involved, however it
|
|
gives a more hands-on experience.
|
|
|
|
Once you've completed **either one** of these steps, you can move onto the next step.
|
|
|
|
## 2. Submit your deposit to Goerli
|
|
|
|
<div class="form-signin" id="uploadDiv">
|
|
<p>Upload the <code>eth1_deposit_data.rlp</code> file from your validator
|
|
directory (created in the previous step) to submit your 3.2 Goerli-ETH
|
|
deposit using Metamask.</p>
|
|
<p>Note that the method you used in step 1 will determine where this file is
|
|
located.</p>
|
|
<input id="fileInput" type="file" style="display: none">
|
|
<button id="uploadButton" class="btn btn-lg btn-primary btn-block"
|
|
type="submit">Upload and Submit Deposit</button>
|
|
</div>
|
|
|
|
<div class="form-signin" id="waitingDiv" style="display: none">
|
|
<p style="color: green">Your validator deposit was submitted and this step is complete.</p>
|
|
<p>See the transaction on <a id="txLink" target="_blank"
|
|
href="https://etherscan.io">Etherscan</a>
|
|
or <a href="">reload</a> to perform another deposit.</p>
|
|
</div>
|
|
|
|
<div class="form-signin" id="errorDiv" style="display: none">
|
|
<h4 class="h3 mb-3 font-weight-normal">Error</h4>
|
|
<p id="errorText" style="color: red">Unknown error.</p>
|
|
<p style="color: red">Please refresh to reupload.</p>
|
|
</div>
|
|
|
|
> This deposit is made using gETH (Goerli ETH) which has no real value. Please 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 stays synced with the network while 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](https://discord.gg/cyAszAh) or [create an
|
|
issue](https://github.com/sigp/lighthouse/issues/new).
|
|
|
|
Don't forget to checkout the open-source block explorer for the Lighthouse
|
|
testnet at
|
|
[lighthouse-testnet3.beaconcha.in](https://lighthouse-testnet3.beaconcha.in/).

|
Happy staking!
