Solidity is a programming language used to create smart contracts on the Ethereum platform. It's designed for writing programs that run automatically without anyone controlling them, allowing users to implement tokens, voting systems, and more. Using Solidity benefits developers by providing a familiar syntax similar to C++ and JavaScript, making it easier to learn and use. Additionally, it supports complex data types and inheritance, which are useful for creating sophisticated smart contracts. This helps developers build secure and reliable decentralized applications (dApps) efficiently.
