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.

Summary

We've reached the end of our journey on smart contract development in Hyperledger Fabric. Let's spend a few moments recapping the key steps:

  • We started by examining the central concept of a multi-party transaction, which represents the mutual agreement by a set of organizations in a network consortium to a change to a set of business objects.
  • We moved on to see how transactions involving these business objects were stored in a distributed ledger replicated across all network organizations, and how it held both the transaction history of these objects and their current value.
  • We discussed how smart contracts operate within a consensus framework, and the operations that need to happen for a smart contract to generate a multi-party transaction that is stored in the ledger.
  • We examined the important interplay between a smart contract and the ledger's current value in generating a transaction response expressed as before- and after-images...
