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.

Building a transaction processor

Sawtooth simplifies the development of applications by separating the core system from the application domain. Application developers only need to focus on implementing their business logic for the enterprise using the transaction processor, with the language of their choice, without needing to know the underlying details of the Sawtooth core system.

Getting ready

In this recipe, we will go through a step-by-step guide to implement a transaction processor, a smart contract, in our example transaction family using the Sawtooth Python SDK.

Python Sawtooth SDK: The Python SDK is installed automatically when you install Hyperledger Sawtooth on AWS. You can import the SDK in Python to verify Python...
