Validator Node

Panduan ini akan bantu kamu untuk setup Validator Node di jaringan 0G Labs.
Untuk dokumentasi resmi, cek di sini.

Kebutuhan

  • CPU: 8 Core
  • Memori: 64 GB RAM
  • Penyimpanan: 1 TB NVME
  • Bandwidth: 100 Mbps (Download / Upload)

Instalasi

1. Install dependency

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

2. Auto-install script dari ITRocket 🚀

Cepat, stabil, dan langsung to the point — seperti yang biasa kita suka di AstroStake.

Kenapa harus buat dari nol kalau udah ada yang rapi dan terbukti?
Terima kasih banyak buat ITRocket yang bikin semuanya simpel dan praktis!

bash
source <(curl -s https://itrocket.net/api/testnet/og/autoinstall/)

3. Setup Wallet

Untuk membuat wallet baru, gunakan perintah ini. Jangan lupa simpan mnemonic-nya!

0gchaind keys add $WALLET

Simpan alamat wallet dan validator

WALLET_ADDRESS=$(0gchaind keys show $WALLET -a)
VALOPER_ADDRESS=$(0gchaind keys show $WALLET --bech val -a)
echo "export WALLET_ADDRESS="$WALLET_ADDRESS >> $HOME/.bash_profile
echo "export VALOPER_ADDRESS="$VALOPER_ADDRESS >> $HOME/.bash_profile
source $HOME/.bash_profile

4. Cek status blok sync

Script dari ITRocket

#!/bin/bash
rpc_port=$(grep -m 1 -oP '^laddr = "\K[^"]+' "$HOME/.0gchain/config/config.toml" | cut -d ':' -f 3)
while true; do
  local_height=$(curl -s localhost:$rpc_port/status | jq -r '.result.sync_info.latest_block_height')
  network_height=$(curl -s https://og-testnet-rpc.itrocket.net/status | jq -r '.result.sync_info.latest_block_height')

  if ! [[ "$local_height" =~ ^[0-9]+$ ]] || ! [[ "$network_height" =~ ^[0-9]+$ ]]; then
    echo -e "mError: Data blok tidak valid. Coba lagi..."
    sleep 5
    continue
  fi

  blocks_left=$((network_height - local_height))
  echo -e "mNode Height:m $local_height m| Network Height:m $network_height m| Sisa Blok:m $blocks_left"
  sleep 5
done

5. Cek status node

Pastikan hasilnya "catching_up": false

0gchaind status 2>&1 | jq

6. Buat Validator

Pastikan saldo kamu cukup. Ganti wallet_name dengan nama wallet kamu.

0gchaind q bank balances $(0gchaind keys show "wallet_name" -a)

Edit Info Validator

Edit moniker, identity, website, dan details sesuai keinginan.

amount 1000000ua0gi = 1 A0GI

0gchaind tx staking create-validator \
--amount 1000000ua0gi \
--from $WALLET \
--commission-rate 0.1 \
--commission-max-rate 0.2 \
--commission-max-change-rate 0.01 \
--min-self-delegation 1 \
--pubkey $(0gchaind tendermint show-validator) \
--moniker "test" \
--identity "" \
--website "" \
--details "I love blockchain ❤️" \
--chain-id zgtendermint_16600-2 \
--gas-adjustment 1.5 --gas auto --gas-prices 0.00252ua0gi \
-y

Cek info validator

Ganti wallet_name dengan wallet kamu:

0gchaind q staking validator $(0gchaind keys show "wallet_name" --bech val -a)

Hapus Node

⚠️ Penting: Backup Kunci Validator Kamu!

Jangan sampai hilang — kunci ini wajib untuk jalankan validator kamu.

Lokasi file: /root/.0gchain/config/priv_validator_key.json

sudo systemctl stop 0gchaind
sudo systemctl disable 0gchaind
sudo rm -rf /etc/systemd/system/0gchaind.service
sudo rm $(which 0gchaind)
sudo rm -rf $HOME/.0gchain
sed -i "/OG_/d" $HOME/.bash_profile
