In the previous chapter, we had an overview of all major concepts related to blockchains, particularly focusing on ones related to Ethereum and discussed the fundamentals related to working with blockchains in general. Ethereum-based blockchain solutions can be deployed to multiple networks. They can be deployed on public networks, test networks, or private networks. This chapter focuses on introducing and deploying Ethereum-based tools and utilities that are needed for building Ethereum-based solutions. There are plenty of tools in the Ethereum ecosystem and this chapter will focus on some of the most important and necessary tools. The tools will be deployed on Windows Server 2016 on Azure Cloud. However, they can be deployed on Linux, Mac, and any virtual machine or physical computer, as well. This will also be used as our development environment...

Solidity Programming Essentials
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.
