Do you think you know something about Bitcoin and Austrian Economics? If so you may be ready for Cryptoeconomics. This is not a work for the uninitiated. The content is dense – it does not repeat itself. It is not a contribution to the echo chamber, will not show you how to set up a wallet, the future price, or what to do. Cryptoeconomics applies rational economic principles to Bitcoin, demonstrating flaws and unnecessary complexities in them, and in common understandings of Bitcoin. It will improve your understanding of both. Bitcoin requires a new, rigorous, and comprehensive discipline. This is it. Bitcoin is something new. It seems to defy understanding. Has there ever been a fixed supply money? Is there another case of production cost varying directly with product price? Is there anything else with a competitive yet fixed rate of transactability? To see past the hype, understand the value proposition, security model, and economic behavior, this may be your only source. Bitcoin is economics, technology, and security. Without incorporating all of these aspects, errors will be made. Economists, technologists, security experts, and even numerologists have attempted to explain it. Each brings a limited perspective, failing to incorporate essential aspects. The author found himself uniquely qualified to integrate them. His work in Bitcoin began with a hardware wallet. He spent a year analyzing threats, working with electronics design, hardware exploitation, and state surveillance experts. He chose the Libbitcoin software library, as Satoshi’s prototype was not factored for development and was largely financed by the Bitcoin Foundation, a corporate consortium. He later dedicated himself to Libbitcoin, eventually writing or editing all of its ~500,000 lines of code. Few have comparable experience with such a comprehensive Bitcoin stack. As a combat-experienced fighter pilot in the U.S. Navy he experienced state threats. He became a highly-qualified Strike Fighter Tactics Instructor, in which his primary role was tactics analysis and threat presentation. He also advised for the Navy on the Strike Fighter Training System network, Joint Strike Fighter, early GPS weapons, and F/A-18 systems. His understanding of the physical nature of all security was enhanced by decades of training in Japanese martial arts, achieving black belt rankings in five disciplines. His degree and experience in computer science mixed with extensive business experience, founding several companies. He has worked at IBM and as a Principle Architect at Microsoft, two of the world’s largest companies. The latter purchased his first startup, and his second was acquired by Veritas Capital. He was awarded three related U.S. patents. Eventually he became an angel investor, sharing his experience with other entrepreneurs. As CTO of his first company he published three computer security advisories via Computer Emergency Response Team. Each was derived entirely from his reading of user documentation. Later he earned a seat on the DHS Open Vulnerability Assessment Language advisory board for his work on software patching. In recent years he uncovered material security flaws in each of the first three iterations of a popular “secure element” hardware wallet, again from review of user documentation. Thirty years of self-study in free market economics was reinforced by extensive global travel. In visiting over 80 countries he has interacted with people on five continents. Still often traveling on a motorcycle with only a shoulder bag, he obtains intimate understanding of global economic realities. From Zimbabwean black market currency traders, to Tanzanian coffee pickers, Venezuelan refugees, Mongolian shepherds, Okinawan jazz musicians, Lao monks, etc. – the world is not as often presented. The ability to integrate these diverse and relevant experiences led to Cryptoeconomics. This is your next stop.

NEW YORK TIMES BESTSELLER • A potent exploration of the power of blockchains to reshape the future of the internet—and how that affects us all—from influential technology entrepreneur and startup investor Chris Dixon “A must for anyone who wants to better understand the real potential of blockchains and web3.”—Robert Iger, CEO, Disney “A compelling vision of where the internet should go and how to get there.”—Sam Altman, co-founder, OpenAI The internet of today is a far cry from its early promise of a decentralized, democratic network of innovation, connection, and freedom. In the past decade, it has fallen almost entirely under the control of a very small group of companies like Apple, Google, and Facebook. In Read Write Own, tech visionary Chris Dixon argues that the dream of an open network for fostering creativity and entrepreneurship doesn’t have to die and can, in fact, be saved with blockchain networks. He separates this movement, which aims to provide a solid foundation for everything from social networks to artificial intelligence to virtual worlds, from cryptocurrency speculation—a distinction he calls “the computer vs. the casino.”   With lucid and compelling prose—drawing from a twenty-five-year career in the software industry—Dixon shows how the internet has undergone three distinct eras, bringing us to the critical moment we’re in today. The first was the “read” era, in which early networks democratized information. In the “read-write” era, corporate networks democratized publishing. We are now in the midst of the “read-write-own” era, sometimes called web3, in which blockchain networks are granting power and economic benefits to communities of users, not just corporations.   Read Write Own is a must-read for anyone—internet users, business leaders, creators, entrepreneurs—who wants to understand where we’ve been and where we’re going. It provides a vision for a better internet and a playbook to navigate and build the future.

Economist Bryan Caplan makes a bold case for unrestricted immigration in this fact-filled graphic nonfiction. American policy-makers have long been locked in a heated battle over whether, how many, and what kind of immigrants to allow to live and work in the country. Those in favor of welcoming more immigrants often cite humanitarian reasons, while those in favor of more restrictive laws argue the need to protect native citizens. But economist Bryan Caplan adds a new, compelling perspective to the immigration debate: He argues that opening all borders could eliminate absolute poverty worldwide and usher in a booming worldwide economy―greatly benefiting humanity. With a clear and conversational tone, exhaustive research, and vibrant illustrations by Zach Weinersmith, Open Borders makes the case for unrestricted immigration easy to follow and hard to deny.
