Blockchain: Home

This book gives business decision makers and students a clear overview of the history, current applications, and future potential of distributed ledgers and cryptocurrency. The hype around blockchain technology is matched only by the innovation it inspires and the skepticism it provokes. This book gives business decision makers and students a clear overview of the history, current applications, and future potential of distributed ledgers and cryptocurrency. It explores strengths and weaknesses, emerging opportunities, and perceived threats. Technical frameworks are presented in a business context to help strategists understand the risks and rewards of different approaches to blockchain implementation, and the decision factors in determining whether this is a viable solution to the problem at hand.

Blockchain is an emerging technology that can radically improve transactions security at banking, supply chain, andother transaction networks. It's estimated that Blockchain will generate $3.1 trillion in new business value by 2030. Essentially, it provides the basis for a dynamic distributed ledger that can be applied to save time when recording transactions between parties, remove costs associated with intermediaries, and reduce risks of fraud and tampering. This book explores the fundamentals and applications of Blockchain technology. Readers will learn about the decentralized peer-to-peer network, distributed ledger, and the trust model that defines Blockchain technology. They will also be introduced to the basic components of Blockchain (transaction, block, block header, and the chain), its operations (hashing, verification, validation, and consensus model), underlying algorithms, and essentials of trust (hard fork and soft fork). Private and public Blockchain networks similar to Bitcoin and Ethereum will be introduced, as will concepts of Smart Contracts, Proof of Work and Proof of Stack, and cryptocurrency including Facebook's Libra will be elucidated. Also, the book will address the relationship between Blockchain technology, Internet of Things (IoT), Artificial Intelligence (AI), Cybersecurity, Digital Transformation and Quantum Computing.

Executives, consultants, and strategists are wondering how to participate in the blockchain economy. They are wondering whether new business models that will emerge because of this novel technology will disrupt theirs or whether they will ignore their businesses and create completely different models. In this book I answer all those questions. By the time you finish, you will understand what blockchain economy is, how to participate in it, and avoid being disrupted or, even worse, ignored. Drawing from my own experiences as research scientist and entrepreneur, the book describes methods to transform existing business by using digitized trust that is industrialized at scale.

This book covers blockchain from the underlying principles to how it enables applications to survive and surf on its shoulder. Having covered the fundamentals of blockchain, the book turns to cryptocurrency. It thoroughly examines Bitcoin before presenting six other major currencies in a rounded discussion. The book then bridges between technology and finance, concentrating on how blockchain-based applications, including cryptocurrencies, have pushed hard against mainstream industries in a bid to cement their positions permanent. It discusses blockchain as underlying banking technology, crypto mining and offering, cryptocurrency as investment instruments, crypto regulations, and markets.

Explore the blockchain-based decentralized platform and understand how Ethereum works with Dapps examples Key Features Explore the Ethereum ecosystem and understand the latest research on the platform Build decentralized apps (Dapps) using smart contracts and Ethereum with the help of practical examples Learn to make your decentralized applications fast and highly secure Book Description Ethereum is a blockchain-based, decentralized computing platform that allows running smart contracts. This book provides a basic overview of how Ethereum works, its ecosystem, mining process, and the consensus mechanism. It also demonstrates a step-by-step approach for building decentralized applications. This book begins with the very basics of Blockchain technology. Then it dives deep into the Ethereum architecture, framework and tools in its ecosystem. It also provides you an overview of ongoing research on Ethereum, for example, Layer 1 and 2 scaling solution, Stablecoin, ICO/STO/IEO, etc. Next, it explains Solidity language in detail, and provides step-by-step instructions for designing, developing, testing, deploying, and monitoring decentralized applications. In addition, you'll learn how to use Truffle, Remix, Infura, Metamask, and many other Ethereum technologies. It'll also help you develop your own cryptocurrency by creating ERC20, and ERC721 smart contracts from scratch. Finally, we explain private blockchains, and you learn how to interact with smart contracts through wallets. What you will learn Understand the concepts of blockchain and cryptocurrency Master Ethereum development tools such as Truffle, Remix IDE and Infura Delve into smart contract development Develop DApps frontend using Node.js, React.js, and Web3js API Learn Etherscan and other tools to secure and monitor smart contracts Develop and debug smart contracts by working with Remix Apply Truffle suite to compile, migrate, and unit test smart contracts Explore smart contracts such as ERC20 token and decentralized digital market Who this book is for This book is for all developers and architects who want to explore Ethereum blockchain fundamentals and get started with building real-world decentralized applications. Knowledge of an object-oriented programming language such as JavaScript will be useful but not mandatory.
