The fascinating untold story of digital cash and its creators—from experiments in the 1970s to the mania over Bitcoin and other cryptocurrenciesBitcoin 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: to protect privacy, bring down governments, prepare for apocalypse, or launch a civilization of innovation and abundance that would make its creators immortal. 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 fascinating untold story of digital cash and its creators—from experiments in the 1970s to the mania over Bitcoin and other cryptocurrenciesBitcoin 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 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.

On contemporary communication in its various human and nonhuman formsContemporary communication puts us not only in conversation with one another but also with our machinery. Machine communication-to communicate not just via but also with machines-is therefore the focus of this volume. Diving into digital communications history, Finn Brunton brings to the fore the alienness of computational communication by looking at network timekeeping, automated trolling, and early attempts at communication with extraterrestrial life. Picking up this fascination with inhuman communication, Mercedes Bunz then performs a close reading of interaction design and interfaces to show how technology addresses humans (as very young children). Finally, Paula Bialski shares her findings from a field study of software development, analyzing the communicative forms that occur when code is written by separate people. Today, communication unfolds merely between two or more conscious entities but often includes an invisible third party. Inspired by this drastic shift, this volume uncovers new meanings of what it means “to communicate.”

How we can evade, protest, and sabotage today's pervasive digital surveillance by deploying more data, not less-and why we should.With Obfuscation, Finn Brunton and Helen Nissenbaum mean to start a revolution. They are calling us not to the barricades but to our computers, offering us ways to fight today's pervasive digital surveillance-the collection of our data by governments, corporations, advertisers, and hackers. To the toolkit of privacy protecting techniques and projects, they propose adding obfuscation: the deliberate use of ambiguous, confusing, or misleading information to interfere with surveillance and data collection projects. Brunton and Nissenbaum provide tools and a rationale for evasion, noncompliance, refusal, even sabotage-especially for average users, those of us not in a position to opt out or exert control over data about ourselves. Obfuscation will teach users to push back, software developers to keep their user data safe, and policy makers to gather data without misusing it.Brunton and Nissenbaum present a guide to the forms and formats that obfuscation has taken and explain how to craft its implementation to suit the goal and the adversary. They describe a series of historical and contemporary examples, including radar chaff deployed by World War II pilots, Twitter bots that hobbled the social media strategy of popular protest movements, and software that can camouflage users' search queries and stymie online advertising. They go on to consider obfuscation in more general terms, discussing why obfuscation is necessary, whether it is justified, how it works, and how it can be integrated with other privacy practices and technologies.

What spam is, how it works, and how it has shaped online communities and the Internet itself.The vast majority of all email sent every day is spam, a variety of idiosyncratically spelled requests to provide account information, invitations to spend money on dubious products, and pleas to send cash overseas. Most of it is caught by filters before ever reaching an in-box. Where does it come from? As Finn Brunton explains in Spam, it is produced and shaped by many different populations around the world: programmers, con artists, bots and their botmasters, pharmaceutical merchants, marketers, identity thieves, crooked bankers and their victims, cops, lawyers, network security professionals, vigilantes, and hackers. Every time we go online, we participate in the system of spam, with choices, refusals, and purchases the consequences of which we may not understand.This is a book about what spam is, how it works, and what it means. Brunton provides a cultural history that stretches from pranks on early computer networks to the construction of a global criminal infrastructure. The history of spam, Brunton shows us, is a shadow history of the Internet itself, with spam emerging as the mirror image of the online communities it targets. Brunton traces spam through three epochs: the 1970s to 1995, and the early, noncommercial computer networks that became the Internet; 1995 to 2003, with the dot-com boom, the rise of spam's entrepreneurs, and the first efforts at regulating spam; and 2003 to the present, with the war of algorithms-spam versus anti-spam. Spam shows us how technologies, from email to search engines, are transformed by unintended consequences and adaptations, and how online communities develop and invent governance for themselves.
