Go beyond the headlines to actually understand the guts of Bitcoin. The 21 Bitcoin Computer provides a steady stream of bitcoin, a recent copy of the Blockchain, and a series of tutorials that take you from Bitcoin novice to expert.
Starting with the basics of cryptographic hashes and digital signatures, these tutorials provide you with hands-on experience using Bitcoin and the Blockchain. Each tutorial contains about one hour of material, to make it easy to learn a little bit every day but still quickly acquire mastery over Bitcoin’s core concepts. The tutorials are brought to you by 21 in partnership with the same folks who taught Stanford’s CS251P Bitcoin course and wrote the official Bitcoin Developer Documentation.
