The trust problem of cryptocurrency

intriguing story and helpful explainer:

…after much deliberation and hand-wringing, in the aftermath of a multimillion-dollar swindle from his automated, algorithm-driven, supposedly foolproof corporation, Vitalik Buterin, then 22 years old, announced the ‘hard fork’ of the cryptocurrency Ethereum. By making that announcement, Buterin shattered certain tightly held assumptions about the future of trust and the nature of many vital institutions that make modern life possible. He also really pissed off a lot of people.
