Book Description
An experimental new Internet-based form of money is created that anyone can generate at home; people build frightening firetrap computers full of video cards, putting out so much heat that one operator is hospitalised with heatstroke and brain damage. A young physics student starts a revolutionary new marketplace immune to State coercion; he ends up ordering hits on people because they might threaten his great experiment, and is jailed for life without parole. Fully automated contractual systems are proposed to make business and the law work better; the contracts people actually write are unregulated penny stock offerings whose fine print literally states that you are buying nothing of any value. The biggest crowdfunding in history attracts $150 million on the promise that it will embody “the steadfast iron will of unstoppable code”; upon release it is immediately hacked, and $50 million is stolen. How did we get here? David Gerard covers the origins and history of Bitcoin to the present day, the other cryptocurrencies it spawned including Ethereum, the ICO craze and the 2017 crypto bubble, and the attempts to apply blockchains and smart contracts to business. Plus a case study on blockchains in the music industry. Bitcoin and blockchains are not a technology story, but a psychology story. Remember: if it sounds too good to be true, it almost certainly is. “A sober riposte to all the upbeat forecasts about cryptocurrency” — New York Review of Books “A very convincing takedown of the whole phenomenon” — BBC News

Libra Shrugged

Publisher: David Gerard
ISBN:

Languages : en
Pages : 180
Book Description
Silicon Valley tries to disrupt the world — and the world says “no.” Facebook: the biggest social network in history. A stupendous, world-shaping success. But governments were giving Facebook trouble over personal data abuses, election rigging and fake news. Mark Zuckerberg wondered: what if Facebook could pivot to finance? Or, better: what if Facebook started its own private world currency? Facebook could have so much power that governments couldn’t stop them. It would be the Silicon Valley dream. Facebook launched Libra in June 2019. Libra would be an international currency and payment system. It would flow instantly around the world by phone. It could even “bank the unbanked.” Libra could apparently do all this just by using a “blockchain.” But Libra would also make Facebook too big to control— and to lead the way for Facebook’s Silicon Valley fellows to swing the power of their money as they pleased. Facebook and their friends could work around any single country’s rules. Libra could shake whole economies. And Facebook would become the “digital identity” provider to the world. If you wanted to use money at all, you’d have to go through Facebook. Governments looked at Libra — and they saw another 2008 financial crisis in the making. Facebook’s plan would have made the company even more entrenched — at the cost of broken economies worldwide. Starting with toppling the US dollar. Libra was as incompetent as it was arrogant — and the world stopped it in its tracks. But how did Facebook put forward such a bizarre and ill-considered plan, that left every regulator who saw it reeling in horror? And what happens when another company tries the same trick? Or when Facebook won’t take “no” for an answer, and releases the cut-down version that they’re already calling “Libra 2.0”? “Libra Shrugged” is the story of a bad idea. Also covered: * Bitcoin and cryptocurrency: the source of all the bad ideas in Libra. * Central Bank Digital Currencies: digital versions of official legal tender, suddenly fashionable again because of Libra. * Facebook’s early forays into payments, with Facebook Credits and Messenger Payments. Table of Contents Introduction: Taking over the money 7 Chapter 1: A user’s guide to Libra 9 Chapter 2: The genesis of Libra: Beller’s blockchain 15 Chapter 3: To launch a Libra: Let’s start a crypto 19 Chapter 4: Bitcoin: why Libra is like this 25 Chapter 5: The Libra White Papers 33 Chapter 6: Banking the unbanked 43 Chapter 7: The Libra Reserve plan and economic stability 49 Chapter 8: Libra, privacy and your digital identity 61 Chapter 9: The regulators recoil in horror 67 Chapter 10: David Marcus before the US House and Senate 77 Chapter 11: July to September 2019: Libra runs the gauntlet 95 Chapter 12: October 2019: Libra’s bad month 101 Chapter 13: Mark Zuckerberg before the US House 111 Chapter 14: November 2019: The comedown 123 Chapter 15: Central bank digital currencies 129 Epilogue: Libra 2.0: not dead yet 141 Appendix: 2010–2013: The rise and fall of Facebook Credits 149 Acknowledgements 155 About the author 157 Index 161 Notes 167

The Politics of Bitcoin
Author: David Golumbia
Publisher: U of Minnesota Press
ISBN: 1452953813
Category : Computers
Languages : en
Pages : 107
Book Description
Since its introduction in 2009, Bitcoin has been widely promoted as a digital currency that will revolutionize everything from online commerce to the nation-state. Yet supporters of Bitcoin and its blockchain technology subscribe to a form of cyberlibertarianism that depends to a surprising extent on far-right political thought. The Politics of Bitcoin exposes how much of the economic and political thought on which this cryptocurrency is based emerges from ideas that travel the gamut, from Milton Friedman, F.A. Hayek, and Ludwig von Mises to Federal Reserve conspiracy theorists. Forerunners: Ideas First is a thought-in-process series of breakthrough digital publications. Written between fresh ideas and finished books, Forerunners draws on scholarly work initiated in notable blogs, social media, conference plenaries, journal articles, and the synergy of academic exchange. This is gray literature publishing: where intense thinking, change, and speculation take place in scholarship.

Blockchain
Author: Mark Van Rijmenam
Publisher: Routledge
ISBN: 0429855559
Category : Business & Economics
Languages : en
Pages : 202
Book Description
The internet was envisaged as a decentralised global network, but in the past 25 years it has come to be controlled by a few, very powerful, centralised companies. Blockchain is a technological paradigm shift that allows secure, reliable, and direct information transfer between individuals, organisations, and things, so that we can manage, verify, and control the use of our own data. Blockchain also offers a new opportunity for humanity to fix some major problems. It can authenticate data, manage its analysis, and automate its use. With better data comes better decision-making. In this way, Blockchain can contribute to solving climate change, reduce voting fraud, fix our identity systems, improve fair trade, and give the poor an opportunity to improve their lives by monetising their (digital) capital. A world built upon peer-to-peer transactions and smart contracts can empower individuals and communities. This book offers a fresh perspective with which to consider this transformative technology. It describes how Blockchain can optimise the processes that run our society. It provides practical solutions to global problems and offers a roadmap to incorporate Blockchain in your business. It offers a blueprint for a better world. Filled with easy-to-understand examples, this book shows how Blockchain can take over where the internet has fallen short.

Book Description
"Mastering Monero - The future of private transactions" is the newest resource to help you learn everything that you want to know about the cryptocurrency Monero. The book, available in electronic and physical form, provides the knowledge you need to participate in this exciting grassroots, open-source, decentralized, community-driven privacy project. Whether you are a novice or highly experienced, this book will teach you how to start using and contributing to Monero. The resource introduces readers to the cryptocurrency world and then explains how Monero works, what technologies it uses, and how you can get started in this fantastic world! For technical people, there are some chapters that provide in-depth understanding of the Monero ecosystem. The Monero cryptocurrency is designed to address and avoid practical troubles that arise from using coins that do not protect your sensitive financial information. Cryptocurrencies have revolutionized the financial landscape by allowing anybody with an internet connection to instantly access secure, robust, censorship-free systems for receiving, storing, and sending funds. This paradigm shift was enabled by blockchain technology, by which thousands of participants store matching copies of a “public ledger”. While this brilliant approach overcomes many economic hurdles, it also gives rise to a few severe downsides. Marketing corporations, snooping governments, and curious family members can analyze the public ledger to monitor your savings or study your activities. Monero mitigates these issues with a suite of advanced privacy technologies that allow you to have the best of all worlds! Instead of a public ledger, Monero has a shared private ledger that allows you to reap the benefits of a blockchain-based cryptocurrency, while protecting your sensitive business from prying eyes. This book contains everything you need to know to start using Monero in your business or day-to-day life. What are you waiting for? Get your copy of Mastering Monero now!

Book Description
A software engineer sets out to design a new political ideology, and ends up concluding that the Stewart Dynasty should be reinstated. A cult receives disturbing messages from the future, where the artificial intelligence they worship is displeased with them. A philosopher suffers a mental breakdown and retreats to China, where he finds the terrifying abyss at the heart of modern liberalism.
