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.

Hyperledger Fabric architecture

The Hyperledger Fabric architecture for N participating organizations is illustrated in the following screenshot. An organization is a business entity that participates in a Hyperledger Fabric-based permissioned blockchain network and deploys the Hyperledger Fabric infrastructure such as peers, ordering nodes, smart contracts, and membership service providers.

In this section, we will describe this architecture in more detail from a security viewpoint:

Fabric CA or membership service provider

The membership service provider (MSP) is responsible for creating digital identities for peers and users of a participating organization, validating identities, and is configured based on the root certificates and CRLs of one or more X.509 CAs. Fabric Certificate Authority (Fabric CA) is the recommended CA server for Fabric deployments, but it is possible to use other CA architectures, or even public...
