➡️ Let’s get started

sudo systemctl restart zenrockd
journalctl -fu zenrockd -o cat

➡️ Log Command

sudo journalctl -fu zenrockd -o cat

➡️ Create wallet

zenrockd keys add wallet-name

➡️ Import wallet

zenrockd keys add wallet-name --recover

➡️ Create Validator

rm -rf $HOME/validator.json

echo "{\"pubkey\":{\"@type\":\"/cosmos.crypto.ed25519.PubKey\",\"key\":\"$(zenrockd comet show-validator | grep -Po '\"key\":\s*\"\K[^"]*')\"},

➡️ Delegate to Yourself

zenrockd tx validation delegate $(zenrockd keys show wallet-name --bech val -a) amount000000urock \
--chain-id gardia-4 \
--from "wallet-name" \
--fees 500000urock

➡️ Edit Validator

zenrockd tx staking edit-validator \

--identity "" \
--details "" \
--website "" \

--node http://localhost:${ZENROCK_PORT}657 \
--fees 500000urock \
-y

➡️ Complete deletion

cd $HOME
sudo systemctl stop zenrockd
sudo systemctl disable zenrockd
sudo rm -rf /etc/systemd/system/zenrockd.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/zenrockd
sudo rm -f $(which zenrockd)
sudo rm -rf $HOME/.zrchain
sed -i "/ZENROCK_PORT_/d" $HOME/.bash_profile

➡️ Block check

local_height=$(curl -s localhost:${ZENROCK_PORT}657/status | jq -r .result.sync_info.latest_block_height); network_height=$(curl -s https://zenrock-testnet-rpc.mictonode.com/status | jq -r .result.sync_info.latest_block_height); blocks_left=$((network_height - local_height)); echo "Your node height: $local_height"; echo "Network height: $network_height"; echo "Blocks left: $blocks_left"

• Your node height - the current block of your node
• Network height - the last block of the network
• Blocks left - how many blocks your node has left to sync.
