Learn to develop blockchain-based distributed ledgers and deploy a Hyperledger Fabric network with concrete exercises and examples

▶Book Description
Blockchain with Hyperledger Fabric - Second Edition is a refreshed and extended version of the successful book on practical Hyperledger Fabric blockchain development. This edition includes many new chapters, alongside comprehensive updates and additions to the existing ones. Entirely reworked for Hyperledger Fabric version 2, this edition will bring you right up to date with the latest in blockchain. Using a real-world Trade Finance and Logistics example, with working code available on GitHub, you'll really understand both how and why Hyperledger Fabric can be used to maximum effect. This book is your comprehensive guide and reference to explore and build blockchain networks using Hyperledger Fabric version 2.

This edition of the book begins by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. Starting from first principles, you'll learn how to design and operate a permissioned blockchain network based on Hyperledger Fabric version 2. You will learn how to configure the main architectural components of a permissioned blockchain network including Peers, Orderers, Certificate Authorities, Channels, and Policies. You'll then learn how to design, develop, package, and deploy smart contracts, and how they are subsequently used by applications. This edition also contains chapters on DevOps, blockchain governance, and security, making this your go-to book for Hyperledger Fabric version 2.

▶What You Will Learn
-Discover why blockchain is a technology and business game changer
-Set up blockchain networks using Hyperledger Fabric version 2
-Understand how to create decentralized applications
-Learn how to integrate blockchains with existing systems
-Write smart contracts and services quickly with Hyperledger Fabric and Visual Studio Code

▶What this book covers
- Chapter 1, Blockchain ？ An Enterprise and Industry Perspective
You've heard about blockchain and you are wondering, What is all the fuss about? In this chapter, we explore why blockchain is a game changer, what innovation it brings, and what the technology landscape looks like.

- Chapter 2, Exploring Hyperledger Fabric
With an understanding of the blockchain landscape, we turn our attention to Hyperledger Fabric. The aim of this chapter is to walk you through the deployment of each component of Hyperledger Fabric while unveiling/building the architecture.

- Chapter 3, Business Networks
This chapter introduces the notion of a business network. By understanding how a business network is structured in terms of participants, assets, transactions, and events, we're able to create a framework for analysing how real-world problems and opportunities can be addressed with blockchain technology. This chapter is helpful for technical architects, software developers, and business analysts.

- Chapter 4, Setting the Stage with a Business Scenario
This chapter describes a business use case and then focuses on understanding the process of creating a good business network using blockchain, from requirements to design and launch, with instructions to set up prerequisite software and a development environment.

- Chapter 5, Designing Smart Contract Transactions and Ledger Data Structure
This chapter talks about how to implement the business logic of the smart contracts of the scenario presented in Chapter 4, Setting the Stage with a Business Scenario, and explores the key concepts and libraries necessary for developing a fully functional contract.

- Chapter 6, Developing Smart Contracts
This chapter introduces the concept of a multi-part transaction; what it is, why it's important, how it's stored in a blockchain ledger, and how it's generated by a smart contract. Starting with first principles, using fully worked examples, you'll understand how blockchain

출판사 서평

▶ Preface
We would like to thank our readers for taking time to consume our collective body of work that is representative of the practice, experience, and knowledge gained throughout our careers.

This book was motivated by the desire that we and others have had to contribute to the evolution of blockchain technologies. We were also challenged by a lack of a comprehensive guide that addresses myriad considerations, including but not limited to technology design choices, architecture choices, business considerations, and governance models. We represent a unique and diverse set of skills, and we have strived to cover a lot of ground in this book. We have collectively focused on organization and flow to ensure not only an easy-to-follow and natural flow but also topical modularity.

The contents of this book are aimed at addressing a diverse audience, from business leaders to blockchain developers and anyone who would like to learn from the practitioners' experience expressed in this book. We believe that not only will the audience enjoy and benefit personally and professionally from the book, but also this book will be used as reference material, a handbook of sorts, and aid in making informed design decisions. We encountered various challenges while writing this book, including our own demanding schedules, but ensured that we delivered up-to-date information at the time of publication. The blockchain technology landscape is in flux and keeping up with evolution and innovation is a challenge. We have attempted to distill a model that will enable the reader to create a framework to methodically consume blockchain-related updates and build upon the foundation laid in this book. We have also expended a lot of energy in addressing business design and resulting technology design choices, because unlike other pure technology platforms, blockchain (particularly blockchain-powered business networks) is a very business-specific and technology-centric discipline.

We hope the findings and documented considerations from practitioners will arm business leaders and technology managers in making informed decisions and avoiding the failures experienced by the authors.

The technical content covered in this book aims to provide a solid foundation for a diverse set of skills to people such as IT professionals, blockchain novices, and advanced blockchain developers. Modeled after a real-world use case, the application development story weaves in various steps from infrastructure creation to DevOps models and model-driven development, covering various enterprise technology management challenges with a focus on the blockchain network-centric impact of application deployment. We have provided a framework for security and performance design that we hope the technical audience finds particularly helpful in establishing a solid foundation as a technology-design consideration.

We'll conclude the book with a pragmatic overview of various challenges and related opportunities, and call for the community of readers to rise to the challenges and reap the rewards of the resulting opportunities. While this book focuses on Hyperledger Fabric, we expect the core topics covered in this book to be universally applicable to the blockchain technology discipline. We sincerely hope that our effort and acumen is well received by our readers and arms them with a strong foundation to make impactful contributions to progressing the blockchain innovation agenda.
