➡️ Let's get started
sudo systemctl start galacticad && sudo journalctl -u galacticad -f --no-hostname -o cat
➡️ Log Command
journalctl -u galacticad -f -o cat
➡️ Create wallet
don't forget to backup the wallet words!
➡️ Import wallet
➡️ Get the EVM address of the wallet you created
➡️ Get the priv key of the wallet you created
➡️ Faucet
➡️ Create Validator
Reminder: You can't create a validator without Sync. You must have to catch the latest block.
➡️ Edit Validator
➡️ Delegation
➡️ Complete deletion
cd $HOME
sudo systemctl stop galacticad
sudo systemctl disable galacticad
sudo rm -rf /etc/systemd/system/galacticad.service
sudo systemctl daemon-reload
sudo rm -f /usr/local/bin/galacticad
sudo rm -f $(which galactica)
sudo rm -rf $HOME/.galactica $HOME/galactica
sed -i "/GALACTICA_/d" $HOME/.bash_profile
➡️ Block check
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.
