wget -P ~/.0gchain/config https://github.com/0glabs/0g-chain/releases/download/v0.1.0/genesis.json

Configure config.toml file

sed -i -e "s/^seeds *=.*/seeds = \"$SEEDS\"/; s/^persistent_peers *=.*/persistent_peers = \"$PEERS\"/" $HOME/.0gchain/config/config.toml

Create a Service File

sudo tee /etc/systemd/system/ogd.service > /dev/null <<EOF
[Unit]
Description=OG Node
After=network.target

[Service]
User=$USER
Type=simple
ExecStart=$(which 0gchaind) start --home $HOME/.0gchain
Restart=10

[Install]

EOF

Start Node

sudo systemctl daemon-reload && \
sudo systemctl enable ogd && \
sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat

Wait a bit until you get the logs. To get out of them press Ctrl+C.

Install Addrbook

curl -Ls https://snapshots.liveraven.net/snapshots/testnet/zero-gravity/addrbook.json > $HOME/.0gchain/config/addrbook.json

Update Peers

PEERS=$(curl -s --max-time 3 --retry 2 --retry-connrefused "https://snapshots.liveraven.net/snapshots/testnet/zero-gravity/peers.txt")
if [ -z "$PEERS" ]; then
    echo "No peers were retrieved from the URL."
else
    echo -e "\nPEERS: "$PEERS""
    sed -i "s/^persistent_peers *=.*/persistent_peers = "$PEERS"/" "$HOME/.0gchain/config/config.toml"
    echo -e "\nConfiguration file updated successfully.\n"
fi

Install Snapshot

sudo systemctl stop ogd
cp $HOME/.0gchain/data/priv_validator_state.json $HOME/.0gchain/priv_validator_state.json.backup
rm -rf $HOME/.0gchain/data
curl -L http://snapshots.liveraven.net/snapshots/testnet/zero-gravity/zgtendermint_16600-1_latest.tar.lz4 | tar -Ilz4 -xf - -C $HOME/.0gchain
mv $HOME/.0gchain/priv_validator_state.json.backup $HOME/.0gchain/data/priv_validator_state.json
sudo systemctl restart ogd && sudo journalctl -u ogd -f -o cat

Check Node Synchronization

0gchaind status | jq .sync_info

Create the Validator

Create a wallet for our validator:

0gchaind keys add $WALLET_NAME --eth

# You may also import an existing wallet
0gchaind keys add --recover $WALLET_NAME --eth

Request private key of the EVM address

0gchaind keys unsafe-export-eth-key $WALLET_NAME

Copy address and import in Metamask

Request Tokens

Now, we go to the faucet and request test tokens

Checking the balance in the terminal

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

Create the validator

0gchaind tx staking create-validator \
  --amount=1000000ua0gi \
  --pubkey=$(0gchaind tendermint show-validator) \
  --moniker="$MONIKER" \
  --chain-id=zgtendermint_16600-1 \
  --commission-rate="0.10" \
  --commission-max-rate="0.20" \
  --commission-max-change-rate="0.01" \
  --details="Your Details" \
  --min-self-delegation="1" \
  --from=$WALLET_NAME \
  --website="link-to-your-website" \
  --identity="Your Identity" \
  --gas=auto \
  --gas-adjustment=1.4

Delegate tokens

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

0gchaind tx staking delegate <validator address> --from <wallet> <amount>ua0gi --gas=auto --gas-adjustment=1.4 -y
