Learn the most powerful primary programming language for writing smart contracts and discover how to write, deploy, and test smart contracts in Ethereum Key Features Get up and running with the Solidity programming language Use Solidity as a scripting language to build smart contracts in Ethereum Learn to test and deploy smart contracts to your private blockchain Book Description Solidity is a contract-oriented language with a syntax that is highly influenced by JavaScript, and designed to compile code for the Ethereum Virtual Machine (EVM). Solidity Programming Essentials is your guide to understanding Solidity programming to build smart contracts for Ethereum and blockchain from ground-up. The book will begin by taking you through concepts like blockchain, and Ethereum, in addition to highlighting their most important components. Next, youll delve into the technicalities of installing the necessary tools to write, test, and debug Solidity contracts on Ethereum. Youll then go on to explore the layout of a Solidity source file and work with the different data types. The next set of recipes will help you to work with operators, control structures, and data structures while building your smart contracts. As you progress further, youll study function calls, return types, function modifiers, and recipes in object-oriented programming with Solidity. Youll also get well-versed with event logging, exception handling, and testing and debugging smart contracts. By the end of this book, youll not only have knowledge of Ethereum and blockchain concepts, but also be able to write, deploy, and test smart contracts in Ethereum. What you will learn Study the basics and foundational concepts of Solidity and Ethereum Explore programming in Solidity and its various nuances Create new accounts and submit transactions to blockchain Understand the language to write smart contracts Discover the major tools for developing and deploying smart contracts Write defensive code using exception handling and error checking Understand Truffle basics and the debugging process Who This Book Is For This beginner-level book is for anyone who wants to get started with Solidity programming for developing Ethereum smart contracts. No prior knowledge of Ethereum Virtual Machine (EVM) is required. Table of Contents Introduction to Blockchain, Ethereum, and Smart Contracts Installing Ethereum and Solidity Introducing Solidity Global Variables and Functions Expressions and Control Structures Writing Smart Contracts Functions, Modifiers, and Fallbacks Exceptions, Events, and Logging Truffle Basics and Unit Testing Debugging Contracts From the Author How to compile Solidity Contracts using Solidity Compiler (Solc) Solidity compiler can be downloaded using the command npm install -g solc This command not only provides access to solc compiler from node environment but it also provides a commandline equivalent (Solcjs)Using solcjs is shown next.

It gets into details about programming language and teaches how to use it for smart contracts. It can be deployed on multiple Blockchain platforms like Hyperledger and Monax. Moreover, It is quite widely adopted for the Ethereum platform. Ethereum provides multiple platforms and environments. These includes test environments like Rinkeby, Kovan, main network and also supports private deployments. This book is not about how to use these platforms. We can use these platforms even
