ETH 2.0 Staking Guide: Prater || Lighthouse

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

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

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.

ETH1 and ETH2 Interacting

This diagram gives an overview of the Eth1 POW and Eth2 POS chains running in parallel.

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.

It's possible to run on ~8gb RAM, but may struggle under stressful network conditions.

The following technologies are used in this guide:

  1. Ubuntu 20.04 LTS - Linux Operating System

  2. Python 3.7 - Programming Language

  3. Go Ethereum - Eth1 Client Software

  4. Lighthouse - Eth2 Client Software

  5. Beaconcha.in - Eth2 Block Explorer

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. 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).

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

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