echo 'export PATH=$PATH:/usr/local/go/bin:$HOME/go/bin' >> $HOME/.bash_profile
source .bash_profile
go version

Set vars

echo "export OG_PORT="47"" >> $HOME/.bash_profile
source $HOME/.bash_profile

Download and build binaries

cd $HOME
rm -rf 0g-chain
git clone -b v0.3.0 https://github.com/0glabs/0g-chain.git
cd 0g-chain
make install

Config and init app

0gchaind config node tcp://localhost:${OG_PORT}657
0gchaind config keyring-backend os
0gchaind config chain-id zgtendermint_16600-2
0gchaind init "your name" --chain-id zgtendermint_16600-2

Create service file

sudo tee /etc/systemd/system/0gchaind.service > /dev/null <<EOF
[Unit]

[Install]
WantedBy=multi-user.target
EOF

Reset and download snapshot

0gchaind tendermint unsafe-reset-all --home $HOME/.0gchain
if curl -s --head curl https://server-5.itrocket.net/testnet/og/og_2024-08-09_586084_snap.tar.lz4 | head -n 1 | grep "200" > /dev/null; then
  curl https://server-5.itrocket.net/testnet/og/og_2024-08-09_586084_snap.tar.lz4 | lz4 -dc - | tar -xf - -C $HOME/.0gchain
    else
  echo "no snapshot founded"
fi

enable and start service

sudo systemctl daemon-reload
sudo systemctl enable 0gchaind
sudo systemctl restart 0gchaind && sudo journalctl -u 0gchaind -f

Becoming a Validator

Create wallet key new

0gchaind keys add $WALLET

(OPTIONAL) RECOVER EXISTING KEY

0gchaind keys add $WALLET --recover

check sync status, once your node is fully synced, the output from above will print "false"

0gchaind status 2>&1 | jq -r '.SyncInfo.catching_up // .sync_info.catching_up'

We receive tokens from the tap in the site

before creating a validator, you need to fund your wallet and check balance

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

Create validator

0gchaind tx staking create-validator \
--amount=1000000ua0gi \
--pubkey=$(0gchaind tendermint show-validator) \
--moniker="Moniker" \
--identity=FFB0AA51A2DF5955 \
--details="I love YTWO❤️" \
--chain-id=zgtendermint_16600-2 \
--commission-rate=0.10 \
--commission-max-rate=0.20 \
--commission-max-change-rate=0.01 \
--min-self-delegation=1 \
--from=wallet \
--gas-prices=0.0025ua0gi \
--gas-adjustment=1.5 \
--gas=auto \
-y 

Update

No update

Current network:zgtendermint_16600-2
Current version:v0.3.0

Useful commands

Check balance

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

CHECK SERVICE LOGS

sudo journalctl -u 0gchaind -f --no-hostname -o cat

RESTART SERVICE

sudo systemctl restart 0gchaind

GET VALIDATOR INFO

0gchaind status 2>&1 | jq -r '.ValidatorInfo // .validator_info'

DELEGATE TOKENS TO YOURSELF

0gchaind tx staking delegate $(0gchaind keys show wallet --bech val -a) 1000000ua0gi --from wallet --chain-id zgtendermint_16600-2 --gas-prices 0.0025ua0gi --gas-adjustment 1.5 --gas auto -y 

REMOVE NODE Please, before proceeding with the next step! All chain data will be lost! Make sure you have backed up your priv_validator_key.json!

sudo systemctl stop 0gchaind && sudo systemctl disable 0gchaind && sudo rm /etc/systemd/system/0gchaind.service && sudo systemctl daemon-reload && rm -rf $HOME/.0gchain && rm -rf 0g-chain && sudo rm -rf $(which 0gchaind)
