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.

Integrating Hyperledger Fabric with Explorer

Hyperledger Explorer is a powerful utility that allows users to create user-friendly web-based applications. It is a blockchain dashboard and provides the ability to view, invoke, deploy, and query raw blockchain data and network information, including block details, chain codes, and transactions stored in the ledger.

Hyperledger Explorer is a highly maintainable and open source browser that can be configured and built natively on macOS and Ubuntu. At the time of writing, Hyperledger Explorer has not yet gone live. The latest release, v0.3.8, supports Fabric v1.3.

It is common to encounter errors here and there, especially around issues related to versions and/or setting up environments. To save time while debugging, I have included various notes and tips, along with recommended fixes, for some of the errors you might run into while...
