Satoshi Nakamoto
Satoshi Nakamoto is a pseudonym for the person or group of people who designed the original Bitcoin protocol in 2008 and launched the network in 2009. Except in connection with Bitcoin, no other links to this pseudonym have been found. Nakamoto was responsible for creating the majority of the Bitcoin software and was active in making modifications and posting technical information on the BitcoinTalk Forum.[9] Nakamoto's involvement does not appear to extend past mid-2010.[9].
Investigations into the real identity of Satoshi Nakamoto have been attempted by The New Yorker and Fast Company. Fast Company's investigation brought up circumstantial evidence linking an encryption patent application filed by Neal King, Vladimir Oksman and Charles Bry on 15 August 2008, and the bitcoin.org domain name which was registered 72 hours later. The patent application (#20100042841) contained networking and encryption technologies similar to Bitcoin's. After textual analysis, the phrase "...computationally impractical to reverse" was found in both the patent application and bitcoin's whitepaper.[1] All three inventors explicitly denied being Satoshi Nakamoto.[43][44] In May 2013 Ted Nelson speculated that Japanese mathematician Shinichi Mochizuki is Satoshi Nakamoto.

In April 2011, Nakamoto communicated to a Bitcoin contributor saying he had “moved on to other things.”[46]
