What is Solidity
Solidity is the programming language used to write smart contracts on Ethereum and similar blockchains. Think of it as the tool developers use to create automated agreements that execute themselves when conditions are met.
When you want to build an app that automatically sends payments, manages voting systems, or handles complex business logic without human intervention, you write that logic in Solidity. The code gets deployed to the blockchain where it runs exactly as programmed – no one can change it or stop it from working.
