As promised, here are the final project presentations from the Bitcoin and cryptocurrency technologies class I taught at Princeton. I encouraged students to build something real, rather than toy class projects, and they delivered. I hope you’ll find these presentations interesting and educational, and that you build on the work presented here (I’ve linked to the projects on GitHub if the code is available).
If you haven’t already, you should sign up for the online version of this class we’re teaching starting in a couple of weeks. The class will prepare you to do projects just like these.
