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.

Exploring the Indy CLI with Hyperledger Indy

In this recipe, we will explore the design and intention for the wallet, Decentralized Identifier (DID), pool, and ledger transaction in Indy network:

  • Wallet: Hyperledger Indy manages identity with a new approach, Decentralized Key Management System (DKMS), which manages identities on distributed ledger technologies such as the blockchain network. DKMS is different from the conventional public key infrastructure (PKI)-based approach to manage identities per certificate, as issued by the centralized CA. In Hyperledger Indy, identities are self-sovereign and are managed by each participant. An identity owner fully controls its identities and credentials and is also independent from any centralized identity providers or certificate authorities.

Identity owners generate and store their private keys, identities, secrets, credentials, and...
