➡️ Let’s get started

sudo systemctl restart junctiond
sudo journalctl -fu junctiond -o cat

➡️ Log Command

sudo journalctl -fu junctiond -o cat

➡️ Create wallet

Warning

Don’t forget to backup the wallet words!

junctiond keys add $AIR_WALLET

➡️ Import wallet

junctiond keys add $AIR_WALLET --recover

➡️ Create Validator

Reminder

You can’t create a validator without Sync. You must have to catch the latest block.

rm -rf /root/validator.json

junctiond tx staking delegate $(junctiond keys show $AIR_WALLET --bech val -a) 1000000uamf --from $AIR_WALLET --chain-id varanasi-1 --fees 5000uamf -y

➡️ Complete deletion

cd $HOME
sudo systemctl stop junctiond
sudo systemctl disable junctiond
sudo rm -rf /etc/systemd/system/junctiond.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/junctiond
sudo rm -f $(which junctiond)

➡️ Block check

local_height=$(junctiond status | jq -r .sync_info.latest_block_height); network_height=$(curl -s https://airchains-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 "MictoNode 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.
