🔌 Installation RPC Node

1️⃣ Install Required Packages

sudo apt update && sudo apt upgrade -y
sudo apt install curl git wget htop tmux build-essential jq make lz4 gcc unzip -y

cd $HOME
VER="1.23.4"
wget "https://golang.org/dl/go$VER.linux-amd64.tar.gz"
sudo rm -rf /usr/local/go
sudo tar -C /usr/local -xzf "go$VER.linux-amd64.tar.gz"
rm "go$VER.linux-amd64.tar.gz"
[ ! -f ~/.bash_profile ] && touch ~/.bash_profile
echo "export PATH=$PATH:/usr/local/go/bin:~/go/bin" >> ~/.bash_profile
source $HOME/.bash_profile
[ ! -d ~/go/bin ] && mkdir -p ~/go/bin

2️⃣ Galileo Node Setup

➡️ Download and Install Node Files

cd $HOME
wget https://github.com/0glabs/0gchain-NG/releases/download/v1.2.0/galileo-v1.2.0.tar.gz
tar -xzvf galileo-v1.2.0.tar.gz -C $HOME
rm -rf $HOME/galileo-v1.2.0.tar.gz
mv $HOME/galileo-v1.2.0 $HOME/galileo-used

➡️ Set Permissions

sudo chmod 777 $HOME/galileo-used/bin/geth
sudo chmod 777 $HOME/galileo-used/bin/0gchaind
mv $HOME/galileo-used/bin/geth $HOME/go/bin/geth
mv $HOME/galileo-used/bin/0gchaind $HOME/go/bin/0gchaind

➡️ Set Environment Variables

Info

You can change OG_PORT to any available base port. All services will use this as a prefix.

echo "export OG_MONIKER=your-moniker-name" >> $HOME/.bash_profile
echo "export OG_PORT=56" >> $HOME/.bash_profile
source $HOME/.bash_profile

➡️ Initialize Geth with Genesis File

mkdir -p $HOME/.0gchaind
cp -r $HOME/galileo-used/0g-home $HOME/.0gchaind

geth init --datadir $HOME/.0gchaind/0g-home/geth-home $HOME/galileo-used/genesis.json

➡️ Initialize 0gchaind

0gchaind init $OG_MONIKER --home $HOME/.0gchaind/tmp

mv $HOME/.0gchaind/tmp/data/priv_validator_state.json $HOME/.0gchaind/0g-home/0gchaind-home/data/

➡️ Start Services

sudo systemctl daemon-reload
sudo systemctl enable geth.service
sudo systemctl start geth.service
sudo systemctl enable 0gchaind.service
sudo systemctl start 0gchaind.service

➡️ Check Logs

sudo journalctl -u 0gchaind -u geth -f

sudo journalctl -u 0gchaind -f -o cat

sudo journalctl -u geth -f -o cat

5️⃣ Wallet Operations

➡️ Create Wallet

➡️ Import Wallet

➡️ Export Private Key

➡️ Faucet

Faucet

6️⃣ Create Validator

Warning

Your node must be fully synced before you can create a validator.

➡️ Delegate

➡️ Block Sync Status Check

local_height=$(curl -s localhost:${OG_PORT}657/status | jq -r .result.sync_info.latest_block_height); 
network_height=$(curl -s http://37.27.60.37:26657/status | jq -r .result.sync_info.latest_block_height); 
blocks_left=$((network_height - local_height)); 
echo "Node height: $local_height"; 
echo "Network height: $network_height"; 
echo "Remaining blocks: $blocks_left"

Node height – the current block height of your node
Network height – the latest block height on the network
Remaining blocks – number of blocks left for your node to fully sync

➡️ Clear Node

Warning

Make sure you have backed up your wallet key & priv_validator_key.json
