Bitcoin may appear to be a revolutionary form of digital cash without precedent or prehistory. In fact, it is only the best-known recent experiment in a long line of similar efforts going back to the 1970s. But the story behind cryptocurrencies like Bitcoin and its blockchain technology has largely been untold鈥攗ntil now. In Digital Cash, Finn Brunton reveals how technological utopians and political radicals created experimental money to bring about their visions of the future: protecting privacy or bringing down governments, preparing for apocalypse or launching a civilization of innovation and abundance that would make its creators immortal.
The incredible story of the pioneers of cryptocurrency takes us from autonomous zones on the high seas to the world鈥檚 most valuable dump, from bank runs to idea coupons, from time travelers in a San Francisco bar to the pattern securing every twenty-dollar bill, and from marketplaces for dangerous secrets to a tank of frozen heads awaiting revival in the far future. Along the way, Digital Cash explores the hard questions and challenges that these innovators faced: How do we learn to trust and use different kinds of money? What makes digital objects valuable? How does currency prove itself as real to us? What would it take to make a digital equivalent to cash, something that could be created but not forged, exchanged but not copied, and which reveals nothing about its users?
Filled with marvelous characters, stories, and ideas, Digital Cash is an engaging and accessible account of the strange origins and remarkable technologies behind today鈥檚 cryptocurrency explosion.

"[Brunton] brings to life the history of efforts to synthesize money out of math and electrons . . . Digital Cash is stocked with colorful characters . . . Readers may at times feel as though they were dropped without explanation into the middle of a dinner party, albeit a delightful one."鈥擪evin Werbach, Los Angeles Review of Books

"The best book I鈥檝e read this year."鈥擩oe Weisenthal, Bloomberg Markets
"On rare occasions a book comes along whose contents are too extraordinary to be believed. It may be the characters, the narrative or perhaps its evocative prose. . . . Digital Cash will raise as many questions as it answers. You may feel elated, amused and even depressed in turn. But like any good book it will lead you to further reading, to new ideas and eventually, perhaps, to enlightenment."鈥擥regory Dobbs, Good Reading
"Digital Cash dives into the history and philosophy of cryptocurrency, unearthing some unforgettable characters along the way."鈥�Happy Magazine

"Brunton鈥檚 book is an important record of concepts and the players that have contributed to
what may represent a whole new phase of civilisation."鈥擲. Ananthanarayanan, The Statesman
鈥淎 fascinating and important book that addresses big questions about cryptocurrency: What is money? How can virtual things have lasting value? And what does the explosion of cryptocurrency mean for the global economy? I can鈥檛 think of another book on the subject that accomplishes so much in such a concise and readable way.鈥濃�擭athan Ensmenger, author of The Computer Boys Take Over
"Brunton's wildly inventive history reveals the dystopian visions that drove the creation of digital cash. Both a lucid unfolding of the technologies inside of money and a thrilling page-turner that takes us from secret WWII-era codebooks to cryopreservation sci-fi, Digital Cash is the rarest of books: engaging, philosophical, and urgent."鈥擳ung-Hui Hu, author of A Prehistory of the Cloud
"Digital Cash is the history of the internet in inverted color. It's a story full of passionate, misguided, utopian, and paranoid characters at the center of a fevered money-dream. From company scrip to Bitcoin, from anticounterfeit technology to missed cryptographic connections, Brunton's book is bedazzling cultural history."鈥擟hristopher M. Kelty, University of California, Los Angeles
鈥淎 very important book.鈥濃�擫ana Swartz, coeditor of Paid: Tales of Dongles, Checks, and Other Money Stuff
"Ever wondered why anyone would build cryptocurrency? Finn Brunton dances across the fantasies that inspired its development. From the demise of governments, to spontaneous market order, to immortality, he shows us that cryptocurrency runs on techno-utopias both familiar and strange and reveals how these far-out visions are shaping our daily realities."鈥擟aitlin Zaloom, New York University
