Bitcoin Engineering (CS251P)
CS251 tackles the applied side of Bitcoin with a focus on practical projects. Students go through a series of Bitcoin-based labs, each of which are focused on a single practical problem that they'd encounter while trying to use Bitcoin. Over the course of going through these labs, students learn how to use Bitcoin mining chips in conjunction with Bitcoin-based software to build micropayments-based applications that work with an internet-connected device. The goal of the class it to help students gain the practical knowledge required to build fairly sophisticated hardware and software applications that require intimate knowledge of the Bitcoin protocol.
