State Sync
Cathing up to the latest block like a magic!
Reset blockchain data
Make sure backup your priv_validator_state.json before reset
sudo systemctl stop bitcanna
cp $HOME/.bcna/data/priv_validator_state.json $HOME/.bcna/priv_validator_state.json.backup
bcnad tendermint unsafe-reset-all --keep-addr-book --home $HOME/.bcna
