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 design goals impacting security

To understand the security of Hyperledger Fabric, it is important to state the key design goals that impact security:

  • Existing members should determine how to add new members to the network: The admission of new entities (members or organizations) to a Hyperledger Fabric-based network must be agreed upon by existing entities in the network. This principle is at the foundation of creating a permissioned blockchain. Instead of allowing any entity to download software and connect to a blockchain network without any verification, the current members in a Hyperledger Fabric-based blockchain network must agree upon a policy to admit new members (such as by majority vote). This policy is then enforced by the underlying mechanisms of Hyperledger Fabric. Upon the successful verification of such an admission policy, the digital credentials of a new member can be added to an existing network.
  • Existing members should determine...
