🚧Let's enable

sudo systemctl daemon-reload
sudo systemctl enable junctiond

🚧Start service and check the logs

sudo systemctl daemon-reload && sudo systemctl start junctiond && sudo journalctl -u junctiond -f --no-hostname -o cat

🚧Check the logs

sudo journalctl -u junctiond -f --no-hostname -o cat

🚧Create wallet

junctiond keys add wallet --keyring-backend os

🚧Wallet import

junctiond keys add wallet --keyring-backend os --recover

🚧Create a validator.json

Not: Get pubkey

junctiond comet show-validator

nano $HOME/validator.json

Not: After editing the code below, write the code above by pasting your edited code into the relevant area. If you encounter an error during validator setup, paste the suggested code again and make the necessary adjustments

{
	"pubkey": <validator-pub-key>,
	"amount": "1000000amf",
	"moniker": "<validator-name>",
	"identity": "optional identity signature (ex. UPort or Keybase)",
