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 Ethereum


What does Ethereum really mean to us? Is it just another cryptocurrency imitating bitcoin or is it just a distributed software platform that can run various applications on a public blockchain? As a software developer, I can assure you that Ethereum is much bigger than how it is currently defined in the standard Wikipedia article.

Take your time to read the following definition. Pause, close your eyes, and think about it. The following definition broadcasts a subtle but very powerful message. It says to us:

Here is a 24/7 computing system, which you can have with zero upfront cost. You can copy it, use it, imitate it, tinker with it, play with it, and tweak it to meet your needs. Not only that, you can invent your own personalized currency with it and offer it whoever is willing to own it. In return, you will provide them with some service, which is permanently defined via a contract on a public ledger, so neither you nor your clients can cheat. Depending on your service...
