Last weekend, I ventured to Spain to attend TADHack 2014. Overall, it was a great event; developers from all around the world gathered in Madrid as well as the many satellite locations across the globe to share creative new ideas spanning topics like distributed GSM networks for rural villages, SMS APIs to summon garbage pickup, and, of course, WebRTC. One of the themes included Bitcoin and payment systems, so I asked myself what happens when you combine instant communications in the browser with distributed, electronic crypto-currencies. What if you could tie payments directly into a session?
Many applications connect you with a premium endpoint, at a cost. Bitcoin could be used to eliminate the need for trust. You wouldn’t have to worry about paying for an hour, just to have the person hang up after two minutes. At the same time, the tutor wouldn’t have fear that you will talk with them for hours and never send payment.
The result was my hack: Trusted Payments With SIP.
