Abstract

Understand the Ethereum platform to build distributed applications that are secured and decentralized using blockchain technology Key Features Build your own decentralized applications using real-world blockchain examples Implement Ethereum for building smart contracts and cryptocurrency applications with easy-to-follow projects Enhance your application security with blockchain Book Description Ethereum enables the development of efficient, smart contracts that contain code. These smart contracts can interact with other smart contracts to make decisions, store data, and send Ether to others.Ethereum Projects for Beginners provides you with a clear introduction to creating cryptocurrencies, smart contracts, and decentralized applications. As you make your way through the book, you'll get to grips with detailed step-by-step processes to build advanced Ethereum projects. Each project will teach you enough about Ethereum to be productive right away. You will learn how tokenization works, think in a decentralized way, and build blockchain-based distributed computing systems. Towards the end of the book, you will develop interesting Ethereum projects such as creating wallets and secure data sharing.By the end of this book, you will be able to tackle blockchain challenges by implementing end-to-end projects using the full power of the Ethereum blockchain. What you will learn Develop your ideas fast and efficiently using the Ethereum blockchain Make writing and deploying smart contracts easy and manageable Work with private data in blockchain applications Handle large files in blockchain applications Ensure your decentralized applications are safe Explore how Ethereum development frameworks work Create your own cryptocurrency or token on the Ethereum blockchain Make sure your cryptocurrency is ERC20-compliant to launch an ICO Who this book is for This book is for individuals who want to build decentralized applications using blockchain technology and the power of Ethereum from scratch. Some prior knowledge of JavaScript is required, since most examples use a web frontend.

Abstract

Blockchains are new technology layers that rewire the Internet and threaten to side-step older legacy constructs and centrally served businesses. At its core, a blockchain injects trust into the network, cutting off some intermediaries from serving that function and creatively disrupting how they operate. Metaphorically, blockchains are the ultimate non-stop computers. Once launched, they never go down, and offer an incredible amount of resiliency, making them dependable and attractive for running a new generation of decentralized services and software applications. The Business Blockchain charts new territory in advancing our understanding of the blockchain by unpacking its elements like no other before. William Mougayar anticipates a future that consists of thousands, if not millions of blockchains that will enable not only frictionless value exchange, but also a new flow of value, redefining roles, relationships, power and governance. In this book, Mougayar makes two other strategic assertions. First, the blockchain has polymorphic characteristics; its application will result in a multiplicity of effects. Second, we shouldn't ask ourselves what problems the blockchain solves, because that gives us a narrow view on its potential. Rather, we should imagine new opportunities, and tackle even more ambitious problems that cross organizational, regulatory and mental boundaries. Drawing on 34 years of technology industry experience as an executive, analyst, consultant, entrepreneur, startup mentor, author, blogger, educator, thought leader and investor, William Mougayar describes a future that is influenced by fundamental shifts brought by blockchain technology as the catalyst for change ... Just as the Internet created new possibilities that we didn't foresee in its early years, the blockchain will give rise to new business models and ideas that may still be invisible.

Abstract

"Deuxième révolution numérique", "ubérisation ultime", "machine à confiance"... la blockchain laisse présager une révolution des usages comparable à celle portée par l'Internet dans les années 90.La promesse de la blockchain est en effet majeure : des transactions instantanées à des coûts minimes et sans organe central de contrôle. Cette technologie a le potentiel de totalement changer les règles du jeu dans de nombreux secteurs économiques, à commencer par le système bancaire. Comment se préparer ? Laurent Leloup décrypte de façon très pédagogique le fonctionnement d'une blockchain, les expériences en cours, les perspectives. Surtout, il pointe les questions à se poser et aide à diagnostiquer les opportunités liées à la blockchain dans chaque secteur. Au-delà des implications économiques, c'est une profonde transformation sociétale qui s'annonce. Car la blockchain est avant tout une révolution de la confiance, portée non plus par un tiers de confiance - banquier, notaire, etc. -, mais par un système décentralisé et partagé. Un nouveau monde se profile [Quatrième de couv.].

Abstract

Ni monnaie fiduciaire, ni moyen de paiement scriptural, le bitcoin est une monnaie électronique inclassable dans l’arsenal des moyens de paiement. Le bitcoin et son protocole associé la Blockchain sont fondés sur une technologie disruptive des échanges sur un réseau distribué et « indélébile » : ils permettent de vérifier, réaliser et enregistrer des transferts – transactions et authentification de documents – en temps réel, à moindres frais en supprimant les intermédiaires potentiellement corruptibles et défaillants. Cette mutation des tiers de confiance bouscule notre mode de pensée et suscite nombre de controverses. Les professionnels intervenant dans les domaines de la finance et de la confiance numérique éprouvent le besoin de comprendre les dimensions stratégiques de ce nouvel outil. Cet ouvrage pédagogique analyse, sans parti pris, les enjeux et les risques liés à cette crypto-monnaie et à la Blockchain : immaturité technique, modèles financiers, cadres réglementaire et sécuritaire. Fruit de l’expertise de quatre spécialistes du paiement, du droit et de la régulation, il éclaire le lecteur sur les perspectives de développement de cette technologie alternative.
