Princeton offers a course, Bitcoin and Cryptocurrency Technologies, through Coursera. First offered in the spring, the course begins once more in September 2015. In a description of the course on the website, the 6 weeks of study are designed to teach “everything you need to be able to separate fact from fiction when reading claims about Bitcoin and other cryptocurrencies. You’ll have the conceptual foundations you need to engineer secure software that interacts with the Bitcoin network. And you’ll be able to integrate ideas from Bitcoin in your own projects.” The school has also offered a free Bitcoin course.
