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.

About Packt


As was the case for the internet in the nineties, blockchain is at the dawn of the Blockchain age. This technology will disrupt existing business models and give birth to new models. It will inspire the emergence of community economies built on a blockchain network, where every participant makes contributions to, and receives benefits from, the community. There is no longer a single entity that controls and receives dividends from the economy.

In this chapter, we have discussed use cases across industries to give you a flavor of potential blockchain applications. Given the limitations of the existing technology, not all these cases can be immediately implemented. As the technology progresses, more use cases can be tackled. Finally, we talked about important factors to be considered in selecting a proper use case and the steps to be followed in developing a complete DApp through an in-depth discussion on the healthcare data sharing use case.
