Who is Satoshi Nakamoto. No one knows who Satoshi Nakamoto really is, but we do know that he published a paper proposing the invention of the Bitcoin protocol back in November 2008, This paper can now be read on the official Bitcoin website, Bitcoin.org.
Nakamoto provided the first version of the bitcoin software client in 2009. He and others contributed towards the development of the project, but by the end of 2010, he made himself a less prominent figure in the rapidly growing Bitcoin community.
