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.

Hyperledger blockchain security

Being different from the public blockchain, Hyperledger Fabric is a permission-based blockchain network. Here, the identity of each node is known and all participants know each other. Since all nodes can trust each other, mining power is not required in order to build trust. This allows us to select various consensus mechanisms, such as the BFT protocol. In the permission blockchain, more centralized identity management prevents Sybil attacks. Participants in the network can transfer, query, and invoke transactions that are controlled by the chain code. Enterprise applications often require complex enterprise security standards. A permissioned network is highly suitable for this scenario.

Hyperledger Fabric provides a modular CA component to issue a certificate for each member in the network. Fabric CA allows user enrollment, issuing, renewing...
