Solidity is a contract-oriented, high-level language for implementing smart contracts. It is designed to target the Ethereum Virtual Machine (EVM) and is used to build decentralized applications (DApps) on the Ethereum blockchain.

Features of Solidity

  • Contract-Oriented: Solidity is primarily used to write smart contracts, which are self-executing contracts with the terms of the agreement directly written into lines of code.
  • High-Level Language: It allows developers to write code in a more human-readable format, making it easier to understand and maintain.
  • EVM Compatibility: Solidity code is compiled into bytecode that can be executed on the Ethereum Virtual Machine.

Syntax and Structure

Solidity code is written in a structured format with a set of rules and conventions. Here are some key elements:

  • Contracts: The basic building blocks of Solidity. They can have state variables, functions, and modifiers.
  • Functions: Used to define the behavior of contracts. They can be public, external, internal, or private.
  • State Variables: Variables that hold the state of a contract. They can be immutable or mutable.

Example

pragma solidity ^0.8.0;

contract SimpleStorage {
    uint256 public storedData;

    function set(uint256 x) public {
        storedData = x;
    }

    function get() public view returns (uint256) {
        return storedData;
    }
}
