📒 Guide: How to become a validator on Eth2

Last updated: November 4th, 2020

Dear Bankless Nation,

Eth2 is here.

That means ETH staking is here. This is the birth of the ether as a digital bond.

The staking contract is open and Eth2 is set to go live on December 1st, 2020. This is years of work finally coming into fruition. And it’s safe to say we’re excited.

That’s why we’re launching this ETH staking guide for those looking to run a validator node on Mainnet. We did one to help people get setup on the Medalla testnet back in August—you can still access the testnet guide to practice by the way.

But now it’s game time. This is the real deal.

Please join me in thanking Collin Myers & Mara Schmiedt from ConsenSys CodeFi & Bison Trails for putting this together—we hope it serves as an invaluable resource for the Ethereum community on getting started with Eth2. 👏

This is the frontier.

1. Hardware Requirements

Based on the decentralized design goals of Eth2, it is expected that validators will utilize a variety of different infrastructure setups (on-premise, cloud, etc).

👉 If you haven’t previously staked your ETH, using the Medalla Testnet is a great way to get involved and gives you sufficient time to determine what type of setup gives you the best, most reliable performance.

Make sure to run some tests before you get started! To test your setup on the Medella testnet first please see here.

Below you will find some hardware recommendations, resource links, and some useful guides to get you prepared.

  • Processor: Intel Core i7-4770 or AMD FX-8310 (or better)
  • Memory: 8GB RAM
  • Storage: 100GB available space SSD
  • Internet: Broadband internet connection (10 Mbps)
  • Power: Uninterruptible power supply (UPS)

2. Choosing & Installing Your Client

The launch of Eth2 features multiple clients, providing validators with the option of using different implementations for running their validator.

As of now, there are 4 client teams with production ready implementations that you can try out:

3. Install an ETH1 Node

Running a validator on Eth2 requires you to run an Eth1 node in order to monitor for 32 ETH validator deposits. There are a variety of options when choosing an Eth1 node, below you will find the tools most commonly used to spin up an Eth1 node.

4. Running an Eth2 Validator

Step 1: Get ETH

If you are new to Ethereum, then a major step is getting your fuel to participate. Eth2 requires 32 ETH per validator. This is the real thing! Recognize that if you end up becoming a validator, you’re making a long term commitment (we’re talking years) towards this initiative.

If you need to top up on some ETH, here’s the exchanges we recommend.

Step 2: Head over to the Eth2 Launchpad

Over the past few months, the Ethereum Foundation (EF), Codefi Activate, and Deep Work Studio have been working on an interface to make it easier for users to stake and become a validator on Ethereum 2.0.

The result of this effort is the Eth2 Launch Pad, an application designed to securely guide you through the process of generating your Eth2 key pairs and staking your 32 ETH into the official deposit contract on Eth2 mainnet.

The Launch Pad was designed for at-home validators. These are hobbyists who intend to run their own validator and are comfortable running commands in a terminal screen on their computer.

Step 2a: Due Diligence (Overview section)

It is important to take your time and read through the content during this part of the journey. The overview section is designed to be educational and informative about the risks involved when staking your ETH.

Step 3: Generate your key pairs and mnemonic phrase

For each validator node, you are required to generate your validator key pair and a mnemonic phrase to generate your withdrawal key later on.

As a first step, you are required to select the number of validators you would like to run and on which operating system you would like to run them on.

The Launchpad will provide you with the two options to generate your deposit keys.

You can find detailed instructions for your operating system here:

The first is to use the binary executable file that you can download from the Eth2 Github repo and then run the ./deposit command in your terminal window.

Please remember to verify the URL and that you are using is the correct one!

The other option is to build the deposit-CLI tool from the Python source code. You will need to follow the instructions to ensure you have all the required development libraries and the deposit-CLI tool installed.

Once you have installed the deposit-CLI tool and run it in your terminal window, you will be prompted to:

  1. Specify the number of validators you would like to run
  2. The language in which you would like to generate your mnemonic phrase
  3. Specify the network (mainnet) on which you would like to run your validator.

Please make sure you have set --chain mainnet for Mainnet testnet, otherwise the deposit will be invalid.

Now you will be asked to set your password and once confirmed your mnemonic phrase will be generated. Make sure you have it written down in a safe place and stored offline!

If you have successfully completed this step you should see the screen below.

If you have questions about the deposit-cli, please visit the GitHub repository:

Step 4: Upload your deposit file

You are almost there! As a next step upload the deposit .json file you generated in the previous step.

It is located in the /eth2.0-deposit-cli/validator_keys directory and is titled deposit-data-[timestamp].json.

Step 5: Connect your wallet

Next connect your Web3 wallet and click continue. Make sure you select Mainnet in your wallet settings.

Step 6: Confirm transaction summary & initiate deposit

Once you have connected and confirmed your wallet address you will be taken to a summary page that displays the total amount of ETH required to send to the deposit contract based on the number of validators you have selected to run.

Consent to the alert checks and click confirm to navigate to the final step — the actual deposit.

Click ‘Initiate the Transaction’ to deposit your ETH into the official Eth2 Deposit Contract.

You will be required to confirm the 32 ETH deposit per validator through your wallet.

Once your transaction is confirmed ….Boom! You’ve made it and can call yourself an official staker for a monumental moment in Web3.

Congratulations!! 🥳

6. Bonus Content & Resources

After reviewing the above steps we recommend that to be validators look through the client specific guides below before getting the process kicked off. The above steps will follow different orders of operations based on which client you decide to work with.

The below guides are the most in depth we have seen in the industry so far and will take Bankless readers through the nuances of the process.
