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.

Designing a namespace and address

In this recipe, we will guide you through the main steps of building a Sawtooth transaction family with a case study that implements a marketplace designed to keep track of the owner of a house. The sample application is developed with the Sawtooth Python SDK and uses the Sawtooth XO transaction family as a template. The full code is available with the source code files that come with this book.

The main focus of this case study is on demonstrating how to develop a Sawtooth application as a proof of concept. In a real production environment, state access control, data encryption, confidentiality, and security would be customized based on the different commercial requirements.

The simple business cases for this sample marketplace are creating records to keep track of the owner of a house and transferring the house from one owner to another:
