How to Run a Validator Node

Requirements:

  • CPU: 1 vCPU
  • Memory: 1 GB RAM
  • Disk: 25 GB HDD or higher
  • Open TCP Ports: 8231, 8085
  • Open UDP Port: 7621

Setup on Ubuntu Server:​

  1. Update OS:
sudo apt update
  1. Install Java:
apt install openjdk-19-jre-headless
  1. Install the validator node software and config file:
wget https://github.com/pwrlabs/PWR-Validator-Node/raw/main/validator.jar
wget https://github.com/pwrlabs/PWR-Validator-Node/raw/main/config.json
  1. Set Up your Password:
sudo nano password
  • Enter your desired password.
  • Press Ctrl + x to close.
  • Press Y to confirm saving the password.
  1. Run the Node: Replace <YOUR_SERVER_IP> with your server's actual IP:
sudo java -jar validator.jar password <YOUR_SERVER_IP> --compression-level 0

PWR Chain is the first chain that supports block compression. --compression-level sets the level of compression you want your node to use. Compression level varies from 0 - 9. 0 disbales compression. 9 sets it to maximum.

  • Upon initialization, the node will generate a wallet, store it locally, and display an address in the format:

    My address: 0xf4b2f12afa634c206bdf5f0dd6dd90f024ad62b7
  1. Become a Validator Node:
  • Initially, your node will synchronize with the blockchain but will not assume validator responsibilities until it possesses staked PWR Coins.
  • To obtain sufficient PWR Coins for staking, apply to become a testnet validator on our Discord server. Once approved, you can use our discord bot to claim 100k PWR to stake.
  • After claiming your coins, your node will initiate a transaction to enlist as a validator.
  1. Running in the Background: If you wish to run the node in the background, ensuring it remains active after closing the terminal, utilize the nohup command:
nohup sudo java -jar validator.jar password <YOUR_SERVER_IP> --compression-level 0 &

Congratulations, you've now set up and run a PWR Chain validator node!
