Cryptoeconomics: Fundamental Principles of Bitcoin

$29.09
( 0.04950141 BCH )

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.

Tyranny without a tyrant: Social media, intolerance, totalitarianism

$14.99
( 0.02550795 BCH )

Social media is changing the community. Several may speak up, but under such apparent freedom of expression, an undercurrent of conformity, obedience, self-censorship, and fear dominates. This is how tolerance turns into intolerance and political freedom into totalitarianism. Distinctive attitudes and individuality are replaced by group affiliation, where those who think differently are ostracized. We sense something disturbing: A community moving toward greater control. And a growing risk of politics with totalitarian features that, instead of fighting for freedom, wants to curtail it.

Deep Utopia: Life and Meaning in a Solved World

$28.75
( 0.04892285 BCH )

Gold Medal Winner, Living Now Book Awards 2024 Best Books of 2024, Kirkus Reviews Winner, Independent Press Awards 2024 Honorable Mention, Royal Dragonfly Book Awards 2024 (Religion/Spirituality) Winner, PenCraft Book Awards 2024 (Fiction: Intrigue) Best AI Books of 2024, The Information Winner, American Book Fest (Nonfiction: Cross-Genre) Winner, 2025 American Legacy Book Award (Nonfiction: Cross-Genre) Bostrom’s last book, Superintelligence: Paths, Dangers, Strategies (OUP, 2014), sparked a global conversation on AI that continues and widens to this day. That book, which despite its academic style became a New York Times bestseller, focused on what would happen if AI goes wrong. But what if AI goes right? Suppose we succeed in developing superintelligence safely and that we make good use of the almost magical powers this unlocks. We would then achieve full unemployment. More than that, we would transition into a “post-instrumental condition," in which human effort is not needed for any practical purpose. This would be a condition of material abundance. Human nature itself would become fully malleable. In such a solved world, what would be the point of human existence? What could give meaning to our lives? Which old values will we have to sacrifice, and which new values will we be able to realize to wonderful degrees? Deep Utopia—a work that is again years ahead of its time—takes the readers on a journey into some of the most profound questions that arise as we dissolve the limits of our current mode of being. It is a lush, playful, difficult, and human text that interleaves fiction stories and philosophical lectures that show us a glimpse of a different kind of existence–one that might be ours in the not-so-distant future.

Un monde engagé dans le difficile passage de la féodalité à la Renaissance, de la théocratie à la science. Un monde ravagé par des guerres et par des ambitions. Mais qui n'est pas notre Terre.

Un médecin, Vossll, qui est aussi une femme, et un guerrier, Dewar. Ils n'ont apparemment rien en commun, sauf de surprenants savoirs. Au jeu de la compassion et de la cruauté, ils vont échanger leurs rôles. Avant peut-être de retourner vers leur véritable univers. Inversions est le cinquième volet du cycle de la Culture. Les quatre précédents, Une forme de guerre, L'Homme des jeux, L'Usage des armes et Excession ont été publiés dans la même collection.
