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.

New features covered in this book

The first edition of this book was published along with Fabric version 1.1. The following is an overview of the new features introduced between version 1.1 and the current version, 2.0:

  • Service discovery: This helps client applications to dynamically discover configuration information about the network peers, cryptographic materials, endorsement policy, and other information needed to submit transactions to the network.
  • State-based endorsement: This allows the contract-level endorsement policy to be overridden by a policy for a specific key(s).
  • Pluggable system contracts: Developers can now develop own consensus models by implementing and deploying own system endorsement (ESCC) and validation (VSCC) contracts.
  • Identity Mixer: This is a new type of membership provider that provides...
