4.1 Go to your "stakepool" folder in the terminal with
4.2 Execute the following command:
./jormungandr --genesis-block-hash $(cat genesis-hash.txt) --config ./itn_rewards_v1-config.yaml
4.3 Once the node starts running, it will take up to an hour before the bootstrap phase is finished, you can track the progress by opening a second Terminal tab and executing the following command:
./jcli rest v0 node stats get --host "http://127.0.0.1:3100/api"
