Ethereum represents the gateway to a worldwide, decentralized computing paradigm. This platform enables you to run decentralized applications (DApps) and smart contracts that have no central points of failure or control, integrate with a payment network, and operate on an open blockchain. With this practical guide, Andreas M. Antonopoulos and Gavin Wood provide everything you need to know about building smart contracts and DApps on Ethereum and other virtual-machine blockchains. Discover why IBM, Microsoft, NASDAQ, and hundreds of other organizations are experimenting with Ethereum. This essential guide shows you how to develop the skills necessary to be an innovator in this growing and exciting new industry. Run an Ethereum client, create and transmit basic transactions, and program smart contracts Learn the essentials of public key cryptography, hashes, and digital signatures Understand how wallets hold digital keys that control funds and smart contracts Interact with Ethereum clients programmatically using JavaScript libraries and Remote Procedure Call interfaces Learn security best practices, design patterns, and anti-patterns with real-world examples Create tokens that represent assets, shares, votes, or access control rights Build decentralized applications using multiple peer-to-peer (P2P) components Annotation If you're looking to get started with the Ethereum protocol--or are among the many open source developers, integrators, and system administrators already working with this platform--Mastering Ethereum is the definitive book on the topic. Authors Gavin Wood and Andreas Antonopoulos provide everything you need to know about building smart contracts and decentralized autonomous organizations on the Ethereum blockchain. By bridging the world of cloud computing, grid computing, and blockchains, Ethereum has created a massive decentralized computing platform that many people are calling a "world computer." Ethereum has also spawned a rapidly growing ecosystem of software startups vying to build decentralized applications, known as "dapps."With this practical guide, you'll learn how to create markets, store registries of debts or promises, move funds in accordance with instructions given long in the past (like a will or a futures contract), and many other things that have not been invented yet, all without a middle man or counterparty risk. Discover why IBM, Microsoft, NASDAQ, and other organizations have announced interest and/or development in this Turing-complete decentralized computing platform with Mastering Ethereum If you're looking to get started with the Ethereum protocol--or are among the many open source developers, integrators, and system administrators already working with this platform--Mastering Ethereum is the definitive book on the topic.
