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.

Bitcoin.org was originally registered and owned by Satoshi Nakamoto and Martti Malmi. When Satoshi left the project, he gave ownership of the domain to additional people, separate from the Bitcoin developers, to spread responsibility and prevent any one person or group from easily gaining control over the Bitcoin project.

Over 950 translators have helped make the site natively display in 25 different languages. In 2017, over 30,000,000 unique visitors visited Bitcoin.org more than 100,000,000 times.
