Blockchain Quick Start Guide

By: Xun (Brian) Wu, Weimin Sun

Overview of this book

Blockchain is a technology that powers the development of decentralized applications.This technology allows the construction of a network with no single control that enables participants to make contributions to and receive benefits from the network directly. This book will give you a thorough overview of blockchain and explain how a blockchain works.You will begin by going through various blockchain consensus mechanisms and cryptographic hash functions. You will then learn the fundamentals of programming in Solidity – the defacto language for developing decentralize, applications in Ethereum. After that, you will set up an Ethereum development environment and develop, package, build, and test campaign-decentralized applications.The book also shows you how to set up Hyperledger composer tools, analyze business scenarios, design business models, and write a chain code. Finally, you will get a glimpse of how blockchain is actually used in different real-world domains. By the end of this guide, you will be comfortable working with basic blockchain frameworks, and develop secure, decentralized applications in a hassle-free manner.

Analyzing business scenarios

In Chapter 5Exploring an Enterprise Blockchain Application Using Hyperledger Fabric, we discussed the blockchain use case for the insurance claim. It includes the following steps:

  1. An insuree reports a claim to a broker
  2. A broker provides requested information


  1. A broker submits a claim to an issuer
  2. An issuer confirms the claim
  3. An issuer processes and approves the claim

In this chapter, we will use the same insurance claim use case, but also build the end-to-end application via Hyperledger Composer.
