Babylon Node Installation Guide

Setting up a Babylon node involves several steps. Follow this guide to successfully install and configure your node.

Step 1: Prepare Your Server

• Ensure your server meets the minimum requirements:

  • CPU: 4 Cores

  • RAM: 8 GB

  • Storage: 100 GB SSD

• Use an operating system such as Ubuntu 20.04 or newer.

Step 2: Install Dependencies

Update your package list and install the necessary development tools:

sudo apt update && sudo apt upgrade -y
sudo apt install curl git build-essential jq -y

Step 3: Install Go

Download and install Go version 1.20.5:

cd $HOME
wget https://dl.google.com/go/go1.20.5.linux-amd64.tar.gz
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf go1.20.5.linux-amd64.tar.gz

Add Go to your PATH:

echo "export PATH=\$PATH:/usr/local/go/bin" >> ~/.profile
source ~/.profile

Step 4: Clone and Build the Babylon Node

1. Clone the Babylon Repository:

cd $HOME
git clone https://github.com/babylon-network/babylon.git
cd babylon

1. Build the Node:

make install

Step 5: Initialize the Node

Initialize your Babylon node with a custom moniker:

babylon init <your-moniker> --chain-id babylon-testnet

Step 6: Download the Genesis File

Download the genesis file necessary for the node to operate:

curl -o ~/.babylon/config/genesis.json https://example.com/path/to/genesis.json

(Replace the URL with the actual link to the genesis file.)

Step 7: Configure the Node

Edit the configuration file to set the seed nodes and persistent peers:

nano ~/.babylon/config/config.toml

Find the lines for seeds and persistent_peers and add the appropriate addresses:

textseeds = "<seed-node-address>"
persistent_peers = "<peer-address-1>,<peer-address-2>"

Step 8: Create a Systemd Service

Create a systemd service file for the Babylon node:

sudo tee /etc/systemd/system/babylon.service > /dev/null <<EOF
[Unit]
Description=Babylon Node
After=network-online.target

[Service]
User=$USER
ExecStart=$(which babylon) start
Restart=always
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

Step 9: Enable and Start the Service

Enable and start the Babylon node service:

sudo systemctl daemon-reload
sudo systemctl enable babylon
sudo systemctl start babylon

Check the logs to ensure everything is running smoothly:

bashsudo journalctl -u babylon -f
