In 25 concise steps, you will learn the basics of blockchain technology. No mathematical formulas, program code, or computer science jargon are used. No previous knowledge in computer science, mathematics, programming, or cryptography is required. Terminology is explained through pictures, analogies, and metaphors.This book bridges the gap that exists between purely technical books about the blockchain and purely business-focused books. It does so by explaining both the technical concepts that make up the blockchain and their role in business-relevant applications.What You'll LearnWhat the blockchain isWhy it is needed and what problem it solvesWhy there is so much excitement about the blockchain and its potentialMajor components and their purposeHow various components of the blockchain work and interactLimitations, why they exist, and what has been done to overcome themMajor application scenariosWho This Book Is For Everyone who wants to get a general idea of what blockchain technology is, how it works, and how it will potentially change the financial system as we know it[...]

La blockchain, surtout connu comme la technologie de base derriere le Bitcoin, est l'une des plus chaudes et des plus intrigantes technologies actuellement sur le marche, mais de quoi s'agit-il exactement - et il peut vous aider en quelque sorte? Simplement mis, la blockchain est l'equivalent numerique d'un grand livre du banquier, un qui enregistre et securise les transactions entre deux parties. Situe dans le cyberespace, ce type de programmation permet le transfert non seulement des donnees, mais de valeur - ce qui le rend un element unique et fondamental de notre avenir emergent. La technologie de la blockchain a ete developpee en 2009 pour permettre aux individus et aux organisations de traiter les transactions sans avoir besoin d'une banque centrale ou d'un autre intermediaire, en utilisant des algorithmes complexes et des consensus pour verifier les transactions. Maintenant, elle a ete adoptee et modifiee par les entreprises et les startups dans le monde entier, et est examinee de pres par les banques mondiales comme la prochaine etape logique dans la finance numerique. Ce livre explique la Blockchain en totalite; son histoire, usages, potentiel, inconvenients, et meme son avenir. Comprendre ce precieux systeme ouvert est essentiel pour creer la liberte financiere[...]

The technology likely to have the greatest impact on the future of the world economy has arrived, and it’s not self-driving cars, solar energy, or artificial intelligence.It’s called the blockchain.The first generation of the digital revolution brought us the Internet of information. The second generation—powered by blockchain technology—is bringing us the Internet of value: a new, distributed platform that can help us reshape the world of business and transform the old order of human affairs for the better.Blockchain is the ingeniously simple, revolutionary protocol that allows transactions to be simultaneously anonymous and secure by maintaining a tamperproof public ledger of value. Though it’s the technology that drives bitcoin and other digital currencies, the underlying framework has the potential to go far beyond these and record virtually everything of value to humankind, from birth and death certificates to insurance claims and even votes.Why should you care? Maybe you’re a music lover who wants artists to make a living off their art. Or a consumer who wants to know where that hamburger meat really came from. Perhaps you’re an immigrant who’s sick of paying big fees to send money home to loved ones. Or an entrepreneur looking for a new platform to[...]

"Views differ on bitcoin, but few doubt the transformative potential of Blockchain technology. The Truth Machine is the best book so far on what has happened and what may come along. It demands the attention of anyone concerned with our economic future." —Lawrence H. Summers, Charles W. Eliot University Professor and President Emeritus at Harvard, Former Treasury SecretaryFrom Michael J. Casey and Paul Vigna, the authors of The Age of Cryptocurrency, comes the definitive work on the Internet’s Next Big Thing: The Blockchain.Big banks have grown bigger and more entrenched. Privacy exists only until the next hack. Credit card fraud is a fact of life. Many of the “legacy systems” once designed to make our lives easier and our economy more efficient are no longer up to the task. Yet there is a way past all this—a new kind of operating system with the potential to revolutionize vast swaths of our economy: the blockchain. In The Truth Machine, Michael J. Casey and Paul Vigna demystify the blockchain and explain why it can restore personal control over our data, assets, and identities; grant billions of excluded people access to the global economy; and shift the balance of power to revive[...]
