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.

Developing an application with Hyperledger Fabric through the SDK

In the previous recipes, we used the fabric-samples prebuilt devmode environment to deploy and test our asset manager chaincode using chaincode-docker-devmode. In this recipe, we will write UI code to interact with chaincode from blockchain. We will also build a Fabric CA container to improve the security of our application. Fortunately, fabric-sample provides the basic-network template, which can help us set up a basic Fabric network.

How to do it...

We first need to write a Fabric script to start the Fabric network and deploy the chaincode in this network. Using the cli container, we then install and instantiate the chaincode. The authorized client with the...
