Solidity Programming Essentials

Overview of this book

Solidity is a contract-oriented language whose syntax is highly influenced by JavaScript, and is designed to compile code for the Ethereum Virtual Machine. Solidity Programming Essentials will be your guide to understanding Solidity programming to build smart contracts for Ethereum and blockchain from ground-up. We begin with a brief run-through of blockchain, Ethereum, and their most important concepts or components. You will learn how to install all the necessary tools to write, test, and debug Solidity contracts on Ethereum. Then, you will explore the layout of a Solidity source file and work with the different data types. The next set of recipes will help you work with operators, control structures, and data structures while building your smart contracts. We take you through function calls, return types, function modifers, and recipes in object-oriented programming with Solidity. Learn all you can on event logging and exception handling, as well as testing and debugging smart contracts. By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum. This book will bring forth the essence of writing contracts using Solidity and also help you develop Solidity skills in no time.

Summary


There was a lot of substance covered in this chapter. Ethereum nodes implement JSON RPC endpoints that can be connected to using WebSockets, IPC, and RPC. In this chapter, we discussed various forms of networks—public, main, test, and private. The chapter also discusses and implements a private network. This chapter had steps to create a development environment that will be used later in subsequent chapters. This chapter focuses on deploying multiple tools and utilities on the Windows operating system. While each tool has its own working and functionality, some tools might eventually do the same thing. For example, a Geth-based private chain and ganache-cli are essentially Ethereum nodes but with differences. Deployment of Geth, Solidity compiler, ganache-cli, web3 JavaScript framework, Mist, and MetaMask were covered in this chapter. While some readers will like working with ganache-cli, others will be interested in using a private Geth-based Ethereum node. There is another important...
