    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 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’s cryptocurrency explosion.

    The cause of their failure was a complete mystery.Five months later, a seemingly unrelated event occurred. A computer security firm in Belarus was called in to troubleshoot some computers in Iran that were caught in a reboot loop—crashing and rebooting repeatedly. At first, technicians with the firm believed the malicious code they found on the machines was a simple, routine piece of malware. But as they and other experts around the world investigated, they discovered a virus of unparalleled complexity and mysterious provenance and intent. They had, they soon learned, stumbled upon the world’s first digital weapon.Stuxnet, as it came to be known, was unlike any other virus or worm built before: It was the first attack that reached beyond the computers it targeted to physically destroy the equipment those computers controlled. It was an ingenious attack, jointly engineered by the United States and Israel, that worked exactly as planned, until the rebooting machines gave it all away. And the discovery of Stuxnet was just the beginning: Once the digital weapon was uncovered and deciphered, it provided clues to other tools lurking in the wild. Soon, security experts found and exposed not one but three highly sophisticated digital spy tools that came from the same labs that created Stuxnet. The discoveries gave the world its first look at the scope and sophistication of nation-state surveillance and warfare in the digital age.Kim Zetter, a senior reporter at Wired, has covered hackers and computer security since 1999 and is one of the top journalists in the world on this beat. She was among the first reporters to cover Stuxnet after its discovery and has authored many of the most comprehensive articles about it. In COUNTDOWN TO ZERO DAY: Stuxnet and the Launch of the World’s First Digital Weapon, Zetter expands on this work to show how the code was designed and unleashed and how its use opened a Pandora’s Box, ushering in an age of digital warfare in which any country’s infrastructure—power grids, nuclear plants, oil pipelines, dams—is vulnerable to the same kind of attack with potentially devastating results. A sophisticated digital strike on portions of the power grid, for example, could plunge half the U.S. into darkness for weeks or longer, having a domino effect on all other critical infrastructures dependent on electricity.
