Ethereum Smart Contract Development

By: Mayukh Mukhopadhyay

Overview of this book

Ethereum is a public, blockchain-based distributed computing platform featuring smart contract functionality. This book is your one-stop guide to blockchain and Ethereum smart contract development. We start by introducing you to the basics of blockchain. You'll learn about hash functions, Merkle trees, forking, mining, and much more. Then you'll learn about Ethereum and smart contracts, and we'll cover Ethereum virtual machine (EVM) in detail. Next, you'll get acquainted with DApps and DAOs and see how they work. We'll also delve into the mechanisms of advanced smart contracts, taking a practical approach. You'll also learn how to develop your own cryptocurrency from scratch in order to understand the business behind ICO. Further on, you'll get to know the key concepts of the Solidity programming language, enabling you to build decentralized blockchain-based applications. We'll also look at enterprise use cases, where you'll build a decentralized microblogging site. At the end of this book, we discuss blockchain-as-a-service, the dark web marketplace, and various advanced topics so you can get well versed with the blockchain principles and ecosystem.

Understanding DApps


Creation of new life always fascinates us, even more so when we are a part of such creation. For instance, consider a zygote cell. Smaller than a tiny speck of sand, it has the ability to grow into a complex biological entity, breathing life into a newborn infant.

But why are we talking about zygotes rather than DApps? Well, a zygote signifies that juncture when one biological cell's generation ends and the next one begins. It acclimates, responding to the outside world without any genetic changes. A zygote cannot be regulated, as it is stuck with its own genes. It can only grow recursively. A zygote is also autonomous. This is because it is still a cell; it's formation is rapidly distributed during the cleavage phase and it is authorized to act as a single entity, apart from other cells. In fact, a zygote is the perfect metaphor of a decentralized application.

An application qualifies as a DApp (pronounced as Dee App, similar to e-book) if it satisfies the following four...
