From this chapter, we will embark on a journey: learning the Solidity language. The previous two chapters introduced blockchains, Ethereum, and their toolsets. Some important concepts related to blockchains, which are essential for having a better understanding and writing efficient code in Solidity, were also discussed. There are multiple languages that target EVM. Some of them are deprecated and others are used with varying degrees of acceptance. Solidity is by far the most popular language for EVM. From this chapter onward, the book will focus on Solidity and its concepts, as well as constructs to help write efficient smart contracts.
In this chapter, we will jump right into understanding Solidity, its structure, data types, and variables. We will cover the following topics in this chapter:
- Solidity and Solidity files
- Structure of a contract
- Data...
