What is the name credited to the designer and creator of the digital currency bitcoin?

Satoshi Nakamoto is the name used by the unknown person or persons who designed bitcoin and created its original reference implementation, Bitcoin Core. As a part of the implementation, Nakamoto also devised the first blockchain database. In the process Nakamoto was the first to solve the double spending problem for digital currency. Nakamoto was active in the development of bitcoin up until December 2010.
