Overview of this book

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.

The steps of setting up the VS Code IDE development environment and cloning the source code of the scenario have been explained in Chapter 4, Setting the Stage with a Business Scenario. We will now learn how to open, run, and debug the code of the trade contract implemented in TypeScript, and then proceed to detailed contract implementation.

In the following exercises, we will use the IBM Blockchain Platform extension of VS Code. At the time of writing, the extension supporting Fabric v2.x is still in beta version. If at the time of practicing these exercises a release supporting v2.x is not yet available, you can use the latest beta version available at the following page:
