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.

Working with Hyperledger Iroha

Hyperledger Iroha is a general-purpose permissioned blockchain system hosted by The Linux Foundation. It was contributed by Soramitsu, Hitachi, NTT DATA, and Colu. Hyperledger Iroha is written in C++ and incorporates the BFT consensus algorithm, named Yet Another Consensus (YAC). Hyperledger Iroha consists of simple deployment and fast development. It can be used in applications that manage digital assets, identity, interbank payment, and so on.

Hyperledger Iroha offers the following key features:

  • Simple deployment with peer nodes
  • Managing accounts and assets in the domain with a role-based permission model
  • Fast development with built-in commands and queries
  • No extra development for smart contracts for common assets and account management
  • An easy and simple Iroha CLI to interact with the network
  • A rich set of client libraries for Java, Python, and...
