In this section, you will learn how to build a complete application around the core smart contract that can be readily used by the business entities that have joined together to form a network. We will begin with a recap of the Hyperledger Fabric transaction pipeline to remind the reader what (and how) a blockchain application does from the perspective of the user (or client). Using code samples, we will show you how to build, design, and organize a network around the needs of business entities, create appropriate configurations, and effect the different stages of a blockchain transaction from start to finish. At the end of this process, the reader will understand how to engineer a Fabric application and expose its capabilities through a simple web interface. The only asset we need to possess in the beginning of this chapter is the contract, or chaincode, which was developed using either hands-on Go programming (see Chapter 4, Designing a data and transaction...

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.
