On October 31, 2008, a quiet Halloween evening, Satoshi@gmx.com sent an email that changed history. The subject was simple: "Bitcoin P2P e-cash paper".
This email sent to the cryptography mailing list said: "I have been working on a new electronic cash system, which is completely peer-to-peer and does not require a trusted third party."
On January 3, 2009, the Bitcoin Genesis Block was mined. In this system, no one can violate the rules of the code. "Code is Law" has changed from Professor Lessig's warning to the ideal of the cryptographic community, and finally found its first complete practice in Bitcoin.
