Overview of this book

Blockchain and Hyperledger technologies are hot topics today. Hyperledger Fabric and Hyperledger Composer are open source projects that help organizations create private, permissioned blockchain networks. These find application in finance, banking, supply chain, and IoT among several other sectors. This book will be an easy reference to explore and build blockchain networks using Hyperledger technologies. The book starts by outlining the evolution of blockchain, including an overview of relevant blockchain technologies. You will learn how to configure Hyperledger Fabric and become familiar with its architectural components. Using these components, you will learn to build private blockchain networks, along with the applications that connect to them. Starting from principles first, you’ll learn to design and launch a network, implement smart contracts in chaincode and much more. By the end of this book, you will be able to build and deploy your own decentralized applications, handling the key pain points encountered in the blockchain life cycle.

Hyperledger Fabric component design

Let's discuss various components that facilitate the blockchain technology tenets of shared ledger, encryption, the trusts system, and smart contracts. The components represent the Hyperledger Fabric infrastructure components and provide isolation from chain code or smart contract development constructs. Chain code or smart contract development details will be discussed in detail in a separate chapter.

The following diagram depicts the Hyperledger Fabric infrastructure components: 

Hyperledger Fabric infrastructure components
Following are the infrastructure components:
  • Hyperledger Fabric CA is an implementation of membership services but is not required to be used (that is, any X509-based PKI infrastructure that can issue EC certificates can be used)
  • Dedicated orderer nodes
    • Implements atomic broadcast API
    • Orders and batches...
