Ben and I have started the basics, Arduino is now reading and writing button presses to serial. The raspberry pi is running a simple serial server that's getting ready to accept JSON info of the form:

{ "device_id": "device_id_here", // device id is unique for every device "consent": true, // always true, future devices may send false // if to_id is an empty string, server will pair first device that consents next // this is bad. don't leave this blank unless you have to "to_id": "second_id_here" // unique id, or empty string }

and will return some similar object to the arduino to parse. Looking forward to getting ESPs running so this json can go online. Blockchain updates to come in a few hours, for now the basics are most important!
