Nine awesome Bitcoin projects at Princeton

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.

Android WebView security and the mobile advertising marketplace

Sign up now for the Bitcoin and cryptocurrency technologies online course

At Princeton I taught a course on Bitcoin and cryptocurrency technologies during the semester that just ended. Joe Bonneau unofficially co-taught it with me. Based on student feedback and what we accomplished in the course, it was extremely successful. Next week I’ll post videos of all the final project presentations.

The course was based on a series of video lectures. We’re now offering these lectures free to the public, online, together with homeworks, programming assignments, and a textbook. We’ve heard from computer science students at various institutions as well as the Bitcoin community about the need for structured educational materials, and we’re excited to fill this need.

We’re using Piazza as our platform. Here’s the course page. To sign up, please fill out this (very short) form.

The first several book chapters are already available. The course starts February 16, and we’ll start making the videos available closer to that date (you’ll need to sign up to watch the videos Edit: we’ve changed this policy; the lectures are also publicly available). Each week there will be a Google hangout with that week’s lecturer. We’ll also answer questions on Piazza.
