# ETH 2.0 Staking Guide: Prater || Lighthouse

Beginners guide to staking on the Eth 2.0 Prater testnet using Lighthouse and Ubuntu 20.04.

{% hint style="info" %}
This serves as a "Hello World" to Eth 2.0, but it requires a basic understanding of Ethereum and Ubuntu command line interface (CLI).

If you're new to Ubuntu and would like to start with the basics, see [Ubuntu for Beginners](https://app.gitbook.com/@agstakingco/s/ethereum-2-0-ubuntu-for-beginners/)
{% endhint %}

## What is Eth 2.0?

When Ethereum was created in 2013, much of the road-map wasn't feasible given the current state of technology. Ethereum 1.0 was launched in 2015 to introduce the Ethereum Virtual Machine (EVM), while Proof-of-Stake (POS) and sharding would be incorporated in the redesigned Ethereum 2.0.

The ETH 2.0 Beacon Chain launched on Dec 1st, 2020 with a total of 21,063 validators, and Eth1 is expected to merge with Eth2 in early 2022.

### **Recommended PC ( i7 / 32GB RAM / 2TB SSD )**

This guide is tailored for a dedicated Ethereum PC/server. A new machine with ( i7 / 32GB RAM / 2TB SSD ) will cost \~$800 and should last through Eth 2.0 - Phase 2.

{% hint style="info" %}
It's possible to run on \~8gb RAM, but may struggle under stressful network conditions.

### ETH 2.0 - Prater Testnet

The Eth2 Prater testnet launched in June 2021, and is the successor to Pyrmont.

### Goerli ETH (GoEth)

Testnets have no value, but each validator on Prater requires a deposit of 32 GoEth. You can request GoEth in the [EthStaker Discord](https://invite.gg/ethstaker). You can use <https://goerli.etherscan.io/> as a Goerli block explorer.

### Linux CLI

You will be running everything from the terminal window (aka Command Line Interface).

{% hint style="info" %}
You can use the following shortcuts for Linux CLI:

* **`Ctrl + Alt + T`**  ||  Open new terminal window
* **`Ctrl + Shift + V`**  ||  Paste contents into terminal window
* **`Ctrl + C`**  ||  Quit terminal process
  {% endhint %}

We'll begin the installation by enabling the Universal Firewall (UFW).
