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.

Chapter 7. Blockchain Use Cases

After completing the first six chapters, you should have sufficient knowledge to think about how to apply your newly acquired skills to resolving real-life problems.  As discussed earlier, blockchain is considered to be a game-changing technology, which can potentially disrupt existing business models by making intermediary services obsolete and inspire the creation of new and cost-effective business models.  However, this technology can not resolve all issues and its value can only be fully realized by combining it with other mature or emerging technologies, such as big data platforms, cloud computing, data science/AI, and IoT.

In this chapter, we first talk about popular blockchain use cases across industries, including financial, civil services, supply chain, IoT, and healthcare, at a high level. We will then proceed to a discussion of factors for consideration, before determining proper use cases and developing a successful DApp. Finally, we take the health...
