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.

Blockchain as a governance tool

So far, in this chapter, we have focused primarily on the human side of governance. We have looked at the impact of the business model on governance, the business processes to consider, and the various potential structures, but what about the technology? What is the effect of the governance model on technology, and how does technology impact governance?

While the primary focus of blockchain projects is on solving business and enterprise issues, the foundation still relies on technology. In this section, we will look at the significant policy capabilities of Hyperledger Fabric and how it can support governance.

Managing network policies

As you now know, the system ledger is used to store the organizations, policies, and channels that make up the network. Storing configurations on the ledger means that any modifications need to be signed and approved.

Hyperledger Fabric is, therefore, excellent from an audit perspective, as it...
