Pyrmont Testnet: Prysm Client - Windows

A guide for non-technical users


The following steps only apply for the Pyrmont Testnet and may be outdated in a few weeks as Ethereum 2.0 clients develop rapidly, however, we will try to keep these documents updated. There are multiple ways on how to get started, we will use the one which is the easiest as of now. Official Prysm docs Prysmatic labs discord server

Choosing Eth1 & Eth2 clients

Head over to the Pyrmont launchpad Choose Geth as your Eth 1 client and in the next step choose Prysm as your Eth 2 client.

Start Ethereum 1.0 Node

  1. Create a folder named prysm in C:\

  2. Download Geth and open a terminal window.

  3. Double click the .exe geth-windows-amd64-x.x.xx-cc05b050. Once the installation is complete there should be geth.exe in the directory chosen during the installation.

  4. Drag and Drop the geth.exe file and add --datadir="C:\prysm" --goerli --http

This terminal window needs to run in parallel to the Ethereum 2.0 node, which will be covered in the next steps. Wait for the Ethereum 1.0 node to be in sync. The logs will look like the following once the node is in sync

Generate Key Pairs

Choose the amount of validators you would like to run and Windows as the operating system. Each validator will cost 32 Goerli ETH. Request Goerli Eth from the r/ethstaker discord here or in the prysmatic labs discord here.

Creating keys

Download the eth2.0-deposit-cli

Move the downloaded file into prysm.

Open a Terminal window and drag&drop the deposit.exe file into the terminal as shown below. Follow the instructions to create your Ethereum 2.0 keys! Drag and drop the Eth2.0-deposit-cli file and add new-mnemonic --chain pyrmont


Let's go to the next page and upload our deposit-data-[timestamp].json file (located in the path shown in the terminal), continue and deposit 32 goerli Eth.

Downloading Prysm

This is only required for the initial setup

Open a Terminal window and run:

  1. cd C:\prysm changes the directory

  2. curl --output prysm.bat Downloads the prysm.bat file

  3. reg add HKCU\Console /v VirtualTerminalLevel /t REG_DWORD /d 1 Changes some vizulations in the terminal window

Importing validator keys

Drag and drop the prysm.bat file and add validator accounts import --keys-dir= AND the path to your newly created keys. For this example the path is C:\Users\Inan\validator_keys

Which results prysm.bat validator accounts import --keys-dir=C:\Users\Inan\validator_keys

Enter a new wallet directory and a new password. In this example we chose C:\prysm as the new wallet directory.

Start the beacon node

Open a new terminal window, drag & drop the prysm.bat file and add beacon-chain --datadir=C:\prysm --http-web3provider=http://localhost:8545/ --pyrmont

Start the validator node

Open a new terminal window, drag & drop the prysm.bat file and add validator --wallet-dir=C:\prysm --datadir=C:\prysm --pyrmont

Enter your wallet password which was set in the previous step. Find the validator public keys in the logs

Enter your wallet password which was set in the previous step. That's it. We are done! Your setup should now have three running terminal windows

Enter your pubkey on the explorer to track its current status and performance. Find out what each of the validator status mean - "What does "Unknown status" mean?"
