In this chapter, we are going to bring together all the concepts we've discussed with a sample business network, involving a real-world example. Specifically, we're going to do a detailed walk-through of the Hyperledger Composer letter of credit sample, so that you can understand how participants, assets, transactions, and events are realized in code. We'll show how the business network is used, analyzed, defined, and how that definition is used to generate APIs, test them, and integrate them into a sample application. This is going to be a comprehensive tour that will get you from concepts right into implementation. We're going to use the letter of credit sample because it represents a well-known process that's often discussed in relation to blockchain. Let's discuss the process first, and then see why it's used as the poster child example.

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.
