Started mining task.Wait a while to mine a block for your transaction to be included in the blockchain, then try checking the balance of 'beb55b6728e45e2cfd45e6c9a146e6693e74cd785dcc91bd7fd4135185d1fc6d0b0ad5c65742d34709a6165124f5ab14'.
With another node running in a seperate terminal window, take the uri from the [2018-08-02 17:33:02 -0700] [2568] [INFO] Goin' Fast @ http://192.168.1.5:8000 of that nodes' startup, and
$ python3 run.py node -port 7999 -sync http://192.168.1.10:8000Of course, logically replace the port with any open port, and the -sync argument with whatever comes in the startup line for the first node.
This is an in-progress way to live monitor your blockchain in your browser. It uses websockets to subscribe to new blocks, and you can access it by opening the index.html file in the explorer folder in your browser or executing open explorer/index.html.
