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

NOT: eski kurulum varsa silelim

systemctl stop 0gchaind
systemctl stop geth
rm -rf $HOME/galileo-used
rm -rf $HOME/.0gchaind

➡️ Download and Install Node Files

wget -O galileo-v3.tar.gz https://github.com/0gfoundation/0gchain-NG/releases/download/v3.0.0/galileo-v3.0.0.tar.gz tar -xzf galileo-v3.tar.gz

cd $HOME
wget https://github.com/0gfoundation/0gchain-NG/releases/download/v3.0.0/galileo-v3.0.0.tar.gz
tar -xzvf galileo-v3.0.0.tar.gz -C $HOME
rm -rf $HOME/galileo-v3.0.0.tar.gz
mv $HOME/galileo-v3.0.0 $HOME/galileo-used

➡️ Set Permissions

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

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

➡️ Initialize 0gchaind

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

cp $HOME/galileo-used/validator/geth-config.toml $HOME/galileo-used/
cp $HOME/galileo-used/validator/kzg-trusted-setup.json $HOME/galileo-used/

➡️ Symlink for client.toml

ln -sf $HOME/.0gchaind/0g-home/0gchaind-home/config/client.toml $HOME/.0gchaind/config/client.toml

3️⃣ Create Service Files

➡️ 0gchaind Service File

sudo tee /etc/systemd/system/0gchaind.service > /dev/null <<EOF
[Unit]
Description=0GChainD Service
After=network.target

[Service]
User=$USER
WorkingDirectory=$HOME/galileo-used
ExecStart=$HOME/go/bin/0gchaind start \
    --rpc.laddr tcp://0.0.0.0:${OG_PORT}657 \
    --chaincfg.chain-spec testnet \
    --home=$HOME/.0gchaind/0g-home/0gchaind-home \
    --p2p.external_address=$(curl -s http://ipv4.icanhazip.com):${OG_PORT}656
Restart=always
RestartSec=5
LimitNOFILE=4096

[Install]
WantedBy=multi-user.target
EOF

➡️ 0ggeth Service File

sudo tee /etc/systemd/system/geth.service > /dev/null <<EOF
[Unit]
Description=0g Geth Node Service
After=network-online.target

[Service]
User=$USER
ExecStart=$HOME/go/bin/geth \
    --config $HOME/galileo-used/validator/geth-config.toml \
    --datadir $HOME/.0gchaind/0g-home/geth-home \
    --networkid 16602 \
    --http.port ${OG_PORT}545 \
    --ws.port ${OG_PORT}546 \
    --authrpc.port ${OG_PORT}551 \
    --port ${OG_PORT}303
Restart=always
WorkingDirectory=$HOME/galileo-used
RestartSec=3
LimitNOFILE=65535

[Install]
WantedBy=multi-user.target
EOF

4️⃣ 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

or

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

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=$(curl -s http://8.218.94.246:26657/status | jq -r .result.sync_info.latest_block_height); 
blocks_left=$((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

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

cd $HOME
sudo systemctl stop 0gchaind geth
sudo systemctl disable 0gchaind geth
sudo rm /etc/systemd/system/0gchaind.service
sudo rm /etc/systemd/system/geth.service
sudo systemctl daemon-reload
sudo rm -f $(which 0gchaind)
sudo rm -f $(which geth)
sudo rm -rf $HOME/.0gchaind
sudo rm -rf $HOME/galileo-used
