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. 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.

Solution application components

As we saw in Chapter 3, Business Networks, individual participants interact with a Hyperledger Fabric network using one or more applications. These are not the applications that run on a user's desktop or phone, or on the device or machine that wishes to transact in the network. Instead, we're going to look at the application that provides the APIs that these desktops, phones, devices, and machines use.

Let's have a look at the main application components in a Hyperledger Fabric network in Figure 6.2:

Figure 6.2: The four basic application components of a solution using Hyperledger Fabric

We can see that there are four major application components in a solution that uses Hyperledger Fabric. We're going to discuss these components in some detail during the next three chapters; let's briefly examine them now to give us a high-level map that will help us navigate.
