Mastering Blockchain Programming with Solidity

By: Jitendra Chittoda

Overview of this book

Solidity is among the most popular and contract-oriented programming languages used for writing decentralized applications (DApps) on Ethereum blockchain. If you’re looking to perfect your skills in writing professional-grade smart contracts using Solidity, this book can help. You will get started with a detailed introduction to blockchain, smart contracts, and Ethereum, while also gaining useful insights into the Solidity programming language. A dedicated section will then take you through the different Ethereum Request for Comments (ERC) standards, including ERC-20, ERC-223, and ERC-721, and demonstrate how you can choose among these standards while writing smart contracts. As you approach later chapters, you will cover the different smart contracts available for use in libraries such as OpenZeppelin. You’ll also learn to use different open source tools to test, review and improve the quality of your code and make it production-ready. Toward the end of this book, you’ll get to grips with techniques such as adding security to smart contracts, and gain insights into various security considerations. By the end of this book, you will have the skills you need to write secure, production-ready smart contracts in Solidity from scratch for decentralized applications on Ethereum blockchain.

Summary

Solidity is a language that executes instructions by consuming gas, and this gas is paid to the Ethereum network's miners. For Solidity instructions to execute, consumers have to buy ether and pay for using the computation and storage resources of the Ethereum blockchain network. Before the innovation of the contract-oriented Solidity language, there was no other language that required crypto fuel to be paid for each instruction's execution. This makes Solidity a unique Turing-complete language. 

We looked into the basics of the Solidity language in this chapter. We also covered the data types supported in Solidity. Solidity is a smart contract-oriented language that uses a very unique data type, called address. This address data type is the heart of the smart contracts. Almost all of the contracts that you will write will most likely use this data...
