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.

Mist wallet


Ethereum works with Ether cryptocurrency and a wallet is required to send and receive Ether. Mist is an implementation of the same. Mist is a wallet used to send and receive Ether. It helps in executing transactions on the Ethereum network. The network can be public or private. It allows users to create their accounts, send and receive Ether, and deploy and invoke contracts.

Mist can be downloaded from https://github.com/ethereum/mist/releases. Download an appropriate ZIP file (in this case it is Ethereum-Wallet-win64-0-9-2.zip since we are deploying on Windows 2016) and extract to a file location. Double-click on the Ethereum Wallet application from the extracted files as shown in the following screenshot:

This should start Mist. Mist is an intelligent wallet. If a private chain is running on a local machine then it can identify the same and connect to it. If there is no local network running, then it will connect to the main network or Rinkeby test network:

However, if a private...
