Overview of this book

Hyperledger is an open-source project and creates private blockchain applications for a range of domains. This book will be your desk reference as you explore common and not-so-common challenges faced while building blockchain networks using Hyperledger services. We'll work through all Hyperledger platform modules to understand their services and features and build end-to-end blockchain applications using various frameworks and tools supported by Hyperledger. This book's independent, recipe-based approach (packed with real-world examples) will familiarize you with the blockchain development cycle. From modeling a business network to integrating with various tools, you will cover it all. We'll cover common and not-so-common challenges faced in the blockchain life cycle. Later, we'll delve into how we can interact with the Hyperledger Fabric blockchain, covering all the principles you need to master, such as chaincode, smart contracts, and much more. We'll also address the scalability and security issues currently faced in blockchain development. By the end of this book, you will be able to implement each recipe to plan, design, and create a full-fledged, private, decentralized application to meet organizational needs.

Implementing Hyperledger Fabric

In the previous chapter, we learned about how to set up and configure Hyperledger Fabric. We explored its key components, including channels, Membership Service Providers (MSPs), the ordering service, and Fabric Certificate Authority (CA).

In this chapter, we are going to build a simple device asset management DApp. We will exploit this example by writing chaincode implemented by various programming languages and we'll also build, test, and deploy our DApp.

First, we will look at inventory asset management, and then the rest of the chapter will be divided into the following recipes:

  • Writing chaincode as a smart contract
  • Compiling and deploying Fabric chaincode
  • Running and testing the smart contract
  • Developing an application with Hyperledger Fabric through the SDK
