In October 2008, someone going by the name Satoshi Nakamoto posted a white paper outlining ‘a peer-to-peer electronic cash system’ called Bitcoin to an arcane listserv populated by Cypherpunks. No one in the community had heard of Nakamoto, and just as people were starting to wonder who he was, he vanished. As the years passed, and the scope of Nakamoto’s achievement became clear, the truth of his identity grew into the greatest unsolved mystery of our time. The Mysterious Mr Nakamoto traces Benjamin Wallace’s attempt to unmask the figure behind the currency and the world it wrought. Nakamoto’s Bitcoin at first seemed destined to fulfill the dreams of fringe 1990s utopians for a currency set free from governments and big banks. Yet after he disappeared, his creation took on a strange new life in the financial markets, where rampant speculation fuelled a vision of crypto as a potential windfall, inviting charlatans and scammers and opening a vast gulf between Bitcoin’s idealistic origins and its troubled reputation. But who was Nakamoto? Whoever he was could rightly claim to have invented one of the most important technologies of the new century. And Nakamoto was a billionaire, his Bitcoin wallet held an untouched eleven-figure fortune waiting to be claimed. New York Times bestselling author Benjamin Wallace presents a page-turning work of investigative journalism.
