Blockchain Application Guide

This book focuses on progress, concerns and approaches of blockchain application. It summarizes basic concepts, principles and standardization of blockchain technology, as well as the status of blockchain application and industry. It provides an ecology model and an evaluation method for blockchain applications and analyses the governance of blockchain applications. It presents application values and practices in financial services, logistics, government service, culture and education, and people’s livelihood and includes analysis of scenarios and use cases. This book is a summary of the experience of more than 20 experts from enterprises and institutions active in the blockchain industry. It provides a panorama of blockchain applications for users, technology and service providers, application developers and operators and supervisors.

Blockchain has become attractive to companies and governments because it promises to solve the age-old problem of mutability in transactions - that is, it makes falsification and recalculation impossible once a transaction has been committed to the technology. However, the perceived complexity of implementing Blockchain calls for an in-depth overview of its key features and functionalities, specifically in a legal context. The systematic and comprehensive approach set forth in this indispensable book, including coverage of existing relevant law in various jurisdictions and practical guidance on how to tackle legal issues raised by the use of Blockchain, ensures a one-stop-shop reference book for anyone considering Blockchain-based solutions or rendering advice with respect to them. Within a clear structure by fields of law allowing for a systematic approach, each contributor - all of them are practitioners experienced with Blockchain projects within their respective areas of expertise - elucidates the implications of Blockchain technology and related legal issues under such headings as the following: technical explanation of Blockchain technology; contract law; regulatory issues and existing regulation in a variety of jurisdictions; data protection and privacy; capital markets; information security; patents and other intellectual property considerations; and antitrust law. Keeping the legal questions and concepts sufficiently generic so that lawyers can benefit from the handbook irrespective of their jurisdiction and legal background, the authors cover such specific characteristics of Blockchain implementation as so-called smart contracts, tokenization, distributed ledger technology, digital securities, recognition of code as law, data privacy challenges and Blockchain joint ventures. Because Blockchain is a relatively new technology still in process and raises a multitude of legal questions, this well-balanced introduction - at a depth that allows non-IT experts to understand the groundwork for legal assessments - provides a solid basis for organizations and their legal advisors in identifying and resolving Blockchain-related issues. Legal practitioners, in-house lawyers, IT professionals and advisors, consultancy firms, Blockchain associations and legal scholars will welcome this highly informative and practical book.

This book provides a comprehensive introduction to blockchain and distributed ledger technology. Intended as an applied guide for hands-on practitioners, the book includes detailed examples and in-depth explanations of how to build and run a blockchain from scratch. Through its conceptual background and hands-on exercises, this book allows students, teachers and crypto enthusiasts to launch their first blockchain while assuming prior knowledge of the underlying technology. How do I build a blockchain? How do I mint a cryptocurrency? How do I write a smart contract? How do I launch an initial coin offering (ICO)? These are some of questions this book answers. Starting by outlining the beginnings and development of early cryptocurrencies, it provides the conceptual foundations required to engineer secure software that interacts with both public and private ledgers. The topics covered include consensus algorithms, mining and decentralization, and many more. “This is a one-of-a-kind book on Blockchain technology. The authors achieved the perfect balance between the breadth of topics and the depth of technical discussion. But the real gem is the set of carefully curated hands-on exercises that guide the reader through the process of building a Blockchain right from Chapter 1.” Volodymyr Babich, Professor of Operations and Information Management, McDonough School of Business, Georgetown University "An excellent introduction of DLT technology for a non-technical audience. The book is replete with examples and exercises, which greatly facilitate the learning of the underlying processes of blockchain technology for all, from students to entrepreneurs.” Serguei Netessine, Dhirubhai Ambani Professor of Innovation and Entrepreneurship, The Wharton School, University of Pennsylvania "Whether you want to start from scratch or deepen your blockchain knowledge about the latest developments, this book is an essential reference. Through clear explanations and practical code examples, the authors take you on a progressive journey to discover the technology foundations and build your own blockchain. From an operations perspective, you can learn the principles behind the distributed ledger technology relevant for transitioning towards blockchain-enabled supply chains. Reading this book, you'll get inspired, be able to assess the applicability of blockchain to supply chain operations, and learn from best practices recognized in real-world examples." Ralf W. Seifert, Professor of Technology and Operations Management at EPFL and Professor of Operations Management at IMD

The accessible, non-technical guide to applying and benefiting from blockchain technology. Blockchain has grown at an enormous rate in a very short period of time. In a business context, blockchain can level the playing field between small and large organisations in several ways: Exact copies of the immutable, time-stamped data is held by all parties, all transactions can be viewed in real time, data blocks are cryptographically linked, all raw materials are traceable and smart contracts ensure no middle-men, ease of audit and reduced friction. The trust, transparency, security, quality and reduced costs of blockchain make it a game-changing technology that crosses sectors, industries and borders with ease. Even though the technologies are ready for adoption, businesses remain largely unaware of their full potential and effective implementation. End users require accurate and up-to-date information on the practical applications of blockchain — Commercializing Blockchain provides it. A practical and easy-to-understand guide to blockchain, this timely book illustrates how this revolutionary technology can be used to transform governments, businesses, enterprises and entire communities.

Blockchain Technology is invented by Bitcoin which makes it the backbone of an innovative type of internet. It is a public and digital ledger that distributes data without allowing its copy. It transacts the information from all the systems of its users so that its registered users can't escape retrospectively. It was invented to smoothen out the process of online transactions. Moreover, its purpose is also to make the transactions secure. That's why it is the most reliable and valid technology that does not even rely on any other software or person.
