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.

Integration design patterns

We will now look at some of the viable integration patterns we have seen in the industry. The list is by no means exhaustive, and even though we have deployed and validated many Hyperledger Fabric solutions, we expect that new patterns will emerge as people and organizations become more comfortable with the technology.

In this section, we consider organizations' preexisting enterprise systems that predate their joining of the network. These systems have their own concepts and paradigms, and we will require a form of abstraction to reconcile the two worlds.

Integrating with an existing system of record

Following is a diagram to illustrate the integration of a blockchain network with an existing system of record:

Most large enterprises looking at joining a business network will eventually aim at integrating their system of record to make sure that...
