Reaload daemon and start nodes

sudo systemctl daemon-reload
sudo systemctl enable 0gchaind
sudo systemctl enable geth
sudo systemctl start 0gchaind
sudo systemctl start geth

Check logs

journalctl -u 0gchaind -u geth -f

Useful commands ⚙️

Node status

0gchaind status 2>&1 | jq

Check logs

sudo journalctl -fu 0gchaind -o cat
sudo journalctl -fu geth -o cat

Bloack sync status
