On this day in 2010, Satoshi Nakamoto posted their final message on the BitcoinTalk forum, a brief post about DoS attack mitigation in Bitcoin software version 0.3.19. After this, Satoshi ceased all public communication with the Bitcoin community, never to be heard from again. The disappearance of Bitcoin's creator is one of the most remarkable acts in technology history -- voluntarily walking away from a creation that would grow to be worth trillions, ensuring Bitcoin would truly belong to no one.
