Start Node

sudo systemctl daemon-reload
sudo systemctl restart 0gchaind

Check logs

sudo journalctl -u 0gchaind.service -f --no-hostname -o cat
  • Ctrl+C
  • Ignore if you are receiving "Reconnecting peers...", You node is syncing for the next hours

Create/Recover Wallet

  • Recover: if you already have a wallet
  • Replace WALLET_NAME
0gchaind keys add WALLET_NAME --eth --recover
  • Create new wallet: if this is your first time
0gchaind keys add WALLET_NAME --eth

Export EVM public address and private key of the 0G wallet

  • replace WALLET_NAME

  • Public address:

echo "0x$(0gchaind debug addr $(0gchaind keys show WALLET_NAME -a) | grep hex | awk '{print $3}')"
  • Private key:
0gchaind keys unsafe-export-eth-key WALLET_NAME

Check if your node is synced (if you only get FALSE you can continue creating a validator)

Get Faucet

Create Validator

  • Replace your NODE_NAME & WALLET_NAME
0gchaind tx staking create-validator \
  --amount=1000000ua0gi \
  --pubkey=$(0gchaind tendermint show-validator) \
  --moniker=NODE_NAME \
  --chain-id=zgtendermint_16600-1 \
  --commission-rate=0.05 \
  --commission-max-rate=0.10 \
  --commission-max-change-rate=0.01 \
  --min-self-delegation=1 \
  --from=WALLET_NAME \
  --identity="" \
  --website="https://github.com/0xMoei" \
  --details="0xMoei Community" \
  --node=http://localhost:16657 \
  -y

Delegate tokens

0gchaind tx staking delegate $(0gchaind keys show WALLET_NAME --bech val -a) 1000000ua0gi --from WALLET_NAME -y

Useful commands

Unjail Node (if your node is jailed)

0gchaind tx slashing unjail --from WALLET_NAME --gas=500000 --gas-prices=99999neuron -y

Active Validators list

0gchaind q staking validators -o json --limit=1000 \
| jq '.validators[] | select(.status=="BOND_STATUS_BONDED")' \
| jq -r '.tokens + " - " + .description.moniker' \
| sort -gr | nl

inActive Validators list

0gchaind q staking validators -o json --limit=1000 \
| jq '.validators[] | select(.status=="BOND_STATUS_UNBONDED")' \
| jq -r '.tokens + " - " + .description.moniker' \
| sort -gr | nl

Wallet Balance

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

Your Validator Status

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

Delete Node

sudo systemctl stop 0gchaind.service
sudo systemctl disable 0gchaind.service
sudo rm /etc/systemd/system/0gchaind.service
rm -rf $HOME/.0gchain $HOME/0g-chain
