Solidity Programming Essentials. - Second Edition

Overview of this book

Solidity is a high-level language for writing smart contracts, and the syntax has large similarities with JavaScript, thereby making it easier for developers to learn, design, compile, and deploy smart contracts on large blockchain ecosystems including Ethereum and Polygon among others. This book guides you in understanding Solidity programming from scratch. The book starts with step-by-step instructions for the installation of multiple tools and private blockchain, along with foundational concepts such as variables, data types, and programming constructs. You’ll then explore contracts based on an object-oriented paradigm, including the usage of constructors, interfaces, libraries, and abstract contracts. The following chapters help you get to grips with testing and debugging smart contracts. As you advance, you’ll learn about advanced concepts like assembly programming, advanced interfaces, usage of recovery, and error handling using try-catch blocks. You’ll also explore multiple design patterns for smart contracts alongside developing secure smart contracts, as well as gain a solid understanding of writing upgradable smart concepts and data modeling. Finally, you’ll discover how to create your own ERC20 and NFT tokens from scratch. By the end of this book, you will be able to write, deploy, and test smart contracts in Ethereum.

Preface

I am not sure when there was last so much of a discussion about a single technology across governments, organizations, communities, and individuals. Blockchain is a technology that is being discussed and debated at length across the world and in many organizations, and with reason. Blockchain is not a technology that has a limited effect on our lives. It has and will have widespread ramifications in our lives. The day is not far off when blockchain will touch almost every aspect of our daily activities—paying bills, making transactions with any organization, receiving a salary, verifying our identity, receiving educational results, and so on. This is just the beginning, and we have just started to understand the meaning of decentralization and its impact.

I have been working on blockchain for quite some time now and have been a crypto-investor for a while. I am a technologist and am completely fascinated by Bitcoin because of the architectural marvel it is. I have never come across such a superior thought process and architecture that actually solves not only economic and social problems but also some technically unsolved problems, such as Byzantine general problems and fault tolerance. It solves the problem of distributed computing at large.

Ethereum is built in a similar fashion, and I was in awe when I first heard about and experienced smart contracts. Smart contracts are one of the greatest innovations to deploy decentralized applications on blockchain and extend it easily with custom logic, policies, and rules.

I have thoroughly enjoyed writing this book and sincerely hope that you also enjoy reading about and implementing Solidity. I have brought in a lot of my Solidity experience and try to make the most of it. I hope this book makes you a better Solidity developer and a superior programmer.

Do let me know if there is anything I can do to make your experience better with this book. I am all ears. Happy learning!
