# Mainnet

{% hint style="warning" %}
While the Dappnode machines have a large enough SSD to hold both Mainnet and Testnet Ethereum chains, you will have lower performance if you try to run both chains simultaneously.

If you are already running a Testnet chain (e.g., Goerli), it is best to [remove or pause those packages](/etherfi/archive/solo-stakers/operation-solo-staker/obol-dvt-explained/dappnode-setup/additional-configuration.md#remove-or-pause-packages).
{% endhint %}

Once you have your Dappnode machine set up, the next step is to install the Ethereum staking packages and begin syncing the chain.

The full node can take a few days to sync, so it's good to get that process started as soon as possible.

{% hint style="info" %}
Client diversity is important, so selecting non-majority clients can help to improve the resiliency and health of the network. When selecting which clients to use, take a look at <https://clientdiversity.org> and consider picking clients that are not majority clients.
{% endhint %}

### Install Ethereum Validator Clients

Navigate to the `Stakers` menu and select the `Ethereum` tab.

Select one Execution Client, one Consensus Client, and you ***MUST*** use MEV Boost with ALL of the following relays (if you activate it after installation, you can pass al the URLs below to the config as a comma-separated list).

{% hint style="warning" %}
You ***MUST*** use MEV Boost. Everyone in the cluster must use MEV Boost and all be connected to the same relays, or you won't be able to sign blinded blocks and return them to the correct relay.

Apply the changes and the chain will then start syncing.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://etherfi.gitbook.io/etherfi/archive/solo-stakers/operation-solo-staker/obol-dvt-explained/dappnode-setup/ethereum-validator-clients/mainnet.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
