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.

Exploring Hyperledger Fabric

The focus of this chapter is the Hyperledger Fabric project—its components, design, reference architecture, and overall enterprise readiness. We will also discuss the broader aim of Linux Foundation (LF) hosted Hyperledger projects and the importance of open source and open standards. The goal is to build an understanding of the diversity of various Hyperledger projects, and what frameworks and tools may be suitable for particular enterprise use cases and software consumption models. While the blockchain technology landscape is constantly in flux, Hyperledger projects represent a structure that supports a mature and peer-reviewed technology geared toward enterprise consumption and fueled by a diverse set of talent and community interests.

This chapter will cover the following topics:
