Overview of this book

Blockchain and Hyperledger technologies are hot topics today. Hyperledger Fabric and Hyperledger Composer are open source projects that help organizations create private, permissioned blockchain networks. These find application in finance, banking, supply chain, and IoT among several other sectors. This book will be an easy reference to explore and build blockchain networks using Hyperledger technologies. The book starts by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. You will learn how to configure Hyperledger Fabric and become familiar with its architectural components. Using these components, you will learn to build private blockchain networks, along with the applications that connect to them. Starting from principles first, you’ll learn to design and launch a network, implement smart contracts in chaincode and much more. By the end of this book, you will be able to build and deploy your own decentralized applications, handling the key pain points encountered in the blockchain life cycle.

Chapter 3. Setting the Stage with a Business Scenario

The first two chapters were focused on setting the stage and defining the landscape of a blockchain project. We now understand how the technology works within a business framework and how the various Hyperledger projects aim to solve the problem of time and trust.

With an understanding of the components that make up Hyperledger Fabric, we will now delve into application design and implementation considerations. The next few chapters will take you through the steps of creating your very own smart contract and then integrating it to an application.

In order to make these exercises relevant, we will leverage a business use case with its roots in some older civilizations: trading and letters of credit.

The chapter's objective will be to introduce the business concept of letter of credit, walk you through the sample scenario we selected, and conclude by setting up our development environment.

In this chapter, we will:

  • Explore letters of credit
  • Review...
