A “highly entertaining” (The Wall Street Journal) investigation into the mysterious identity of Bitcoin’s creator and a deep dive into crypto’s utopian origin story—from The New York Times bestselling author of The Billionaire’s Vinegar

“Could be the best mystery story of the past twenty years.”—James Patterson

“The Mysterious Mr. Nakamoto will leave you amazed, enlightened, and utterly breathless.”—Robert Kolker, #1 New York Times bestselling author of Hidden Valley Road

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 fueled 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.

With the same propulsive-narrative flair that made his New York Times bestseller The Billionaire’s Vinegar an instant success, Benjamin Wallace presents a page-turning work of investigative journalism. Tracking leads from London to Oslo to Los Angeles, from coastal Australia to the Arizona desert, he takes readers through a rogues’ gallery tour of Nakamoto suspects—from benevolent geniuses like cryptographer Hal Finney to difficult ones like a reclusive polymath known to his followers only as Jim; from the mercurial Australian Craig Wright, who claims to be Nakamoto, to a secret team at the National Security Agency. With the forensic skill of Sherlock Holmes and the storytelling verve of Arthur Conan Doyle, Wallace follows the trail of computer code and personal writings to the heart of the Nakamoto mystery while interrogating the very nature of mystery itself.
