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.

Interacting with Hyperledger Iroha using the client library

The Iroha client library is the easiest way to build your own DApps with the Iroha network. The Iroha client application is easy to develop using builders that are present in the Iroha client library, and it communicates with the Iroha network with gRPC transport.

In this recipe, we will use the Iroha Python client library to implement a sample client application to interact with the Iroha network. This will perform the following transactions:

  • Transfer the hotcoin asset we created in previous recipe between accounts
  • Query the hotcoin account balance

Getting ready

To build and work with the Iroha client library, the following dependencies should be installed:

  • automake...
