The irony is that many of the big players in the crypto world once worked at Facebook. Dozens of Facebook alumni have left the company in recent years to join the blockchain boom.

The engineering and management experience earned while working on a major tech product like Facebook's 2-billion member social network — along with the financial windfall many employees received in the 2012 IPO — have left the Facebook veterans well-positioned to build a new crop of crypto and blockchain startups.
