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.

Summary


This chapter was more of a lab exercise with minimal theoretical backing. We started it with a simple hello world smart contract on remix IDE, using a web browser. We also explored the increment and decrement operation using a contract. We then jumped in to code a quick for loop in Solidity and proceeded to learn how to consult while troubleshooting and raise issues on GitHub. We closed the chapter by creating a private blockchain using a geth console, mining blocks, earning rewards in ethers, and using those ethers to deploy and execute smart contracts in the MIST browser.

In Chapter 4, A Noob's Guide to DApps and DAO, we will take on the topic of decentralized applications and DAOs.
