Digital Cash: The Unknown History of Cryptocurrency | City Lights

Submitted by the Event Organizer

The fascinating untold story of digital cash and its creators—from experiments in the 1970s to the mania over Bitcoin and other cryptocurrencies

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—until 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’s 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 exchanged but not copied, created but not forged, 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’s cryptocurrency explosion.

“A 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’t think of another book on the subject that accomplishes so much in such a concise and readable way.”—Nathan Ensmenger, author of The Computer Boys Take Over

“A very important book.”—Lana Swartz, coeditor of Paid: Tales of Dongles, Checks, and Other Money Stuff
