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.

DACs and DAS


We have devoted an entire chapter to decentralized autonomous organization (DAO). We also discussed at length, the infamous DAO hack and the vulnerabilities associated with its sloppy programming.

In this section, we will try to understand two similar-sounding concepts that are easily confused with a DAO. These are decentralized autonomous corporations (DACs) and decentralized autonomous society (DAS).

To fuel our confusion, it is also true that DACs are a subset of DAO. The term DAC was coined by Daniel Larimer. He stated that DACs pay dividends, while DAOs are inherently non-profit. In a DAC, shares are purchasable and tradable in some fashion, and those shares potentially entitle their holders to continual receipts based on the DAC's success. Of course, we can make money from a DAO, but not by investing in it; by participating in its ecosystem.

As stated by Vitalik Buterin, the distinction between DAO and DAC is more of a fluid one and hinges on emphasizing to what extent dividends...
