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.

Solidity Design Patterns

The Solidity language is a contract-oriented programming language. There are many constructs required for contract interaction. Also, due to the limitations of the language, few data structure-specific design patterns are used.

In this chapter, you will learn about the different design patterns, that are grouped into different categories based on their usage. These categories are as follows:

  • Security design patterns
  • Creational patterns
  • Behavioral patterns
  • Economic patterns
  • Life cycle patterns

Out of these categories, some of the design patterns that are mostly used in Solidity contracts are listed here:

  • The withdrawal pattern to withdraw ether from the contract
  • The factory contract pattern to create new contracts
  • The state machine pattern to transition a contract from different states
  • The tight variable packing to reduce gas consumption when using structs...
