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 the design of DAO


Is a DAO a smart contract? Is a DAO a DApp? Vitalik Buterin has described the decentralized autonomous organization as an entity that lives on the World Wide Web and has its own set of rules. DAO also heavily relies on hiring individuals to perform certain tasks that the automaton itself cannot do.

Grasping the concept of DAO can be bit tricky. From a software developer's perspective, a DAO is just a piece of code, specifically a complex smart contract, or an interacting module comprising many simple smart contracts, which are abstracted as an organization. From a trader's perspective, the closest analogy of DAO is a Limited Liability Company (LLC). Let's try to understand a bit about LLC. Suppose Susan has a great business idea and wants to open a start-up with her life-savings. Rather than going through the venture capitalist route to fund the rest of the money for doing business, she chose to go the LLC route. That way, she invites shareholders to own a...
