American software developer who was handpicked by Satoshi Nakamoto to be Bitcoin's lead maintainer. DOJ-released EFTA emails show Epstein sought contact with Andresen in June 2011 through literary agent John Brockman and tech investor Jason Calacanis. Epstein's assistant Lesley Groff invited Andresen to meet at Harvard on June 17-18, 2011.
Andresen declined, replying ‘No, sorry, I'm busy.’ No further contact is documented. The outreach occurred two days before Andresen briefed the CIA on Bitcoin.
