Satoshi Nakamoto is the founder of Bitcoin and initial creator of the Original Bitcoin client. 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.
Satoshi Nakamoto interesting quotes:
Yes, [we will not find a solution to political problems in cryptography,] but we can win a major battle in the arms race and gain a new territory of freedom for several years.
Governments are good at cutting off the heads of a centrally controlled networks like Napster, but pure P2P networks like Gnutella and Tor seem to be holding their own.
It’s very attractive to the libertarian viewpoint if we can explain it properly. I’m better with code than with words though.
