According to legend, Satoshi Nakamoto began working on the Bitcoin concept in 2007. While he is on record as living in Japan, it is speculated that Nakamoto may be a collective pseudonym for more than one person. He has said in a P2P foundation profile that he is from Japan. Beyond that, not much else is known about him and his identity. He has been working on the Bitcoin project since 2007.
“The root problem with conventional currency is all the trust that's required to make it work. The central bank must be trusted not to debase the currency, but the history of fiat currencies is full of breaches of that trust.”Satoshi Nakamoto
