Satoshi Nakamoto is the name used by the person or people who designed bitcoin and created the original reference implementation now called Bitcoin Core (formerly known as Bitcoin-Qt).

In October 2008, Satoshi Nakamoto published the Bitcoin whitepaper, entitled "Bitcoin: A Peer-to-Peer Electronic Cash System." The paper was published to a cryptography mailing list describing a "new electronic cash system" which as come to be bitcoin the digital currency. Nakamoto released the first bitcoin software version. The first bitcoin transaction took place on the blockchain on January 3, 2009.

Embedded into the first bitcoin transaction was a message from Nakamoto which read "The Times 03/Jan/2009 Chancellor on brink of second bailout for banks" which is view-able in a blockchain explorer when looking at bitcoin transaction 4a5e1e4baab89f3a32518a88c31bc87f618f76673e2cc77ab2127b7afdeda33b. The first transaction is part of the Genesis block.

Nakamoto continued to work on the bitcoin project until he mysteriously disappeared in 2010. His last message ever publicly made [1] was to the SourceForge Bitcoin Mailing List where he added changes to help with DoS protection. Before his departure, Nakamoto handed over control of the bitcoin development to Gavin Andresen.
