TLDR

Solidity is the programming language for writing smart contracts on Ethereum, programs that run on a decentralized blockchain exactly as written, enabling tokens, voting systems, and financial protocols without a central authority.

Difficulty · moderate Time to first run · 30min

Requires either installing a local Ethereum node/compiler or using Remix IDE; writing and deploying contracts needs testnet setup or local blockchain.

In plain English

Solidity is the programming language used to write smart contracts on the Ethereum blockchain. A smart contract is a program that lives on the blockchain, a decentralized, public ledger, and runs exactly as written without anyone being able to alter or censor it. Smart contracts enable things like tokens, digital ownership records, decentralized voting systems, automated payments, and more, all without a central authority. Solidity is a high-level, statically-typed language (meaning you declare what type of data each variable holds, and the compiler checks for mistakes before deployment). Its syntax is similar to JavaScript or C++. You write Solidity code, compile it using the Solidity compiler, and deploy the compiled result to the Ethereum network, where it executes on the Ethereum Virtual Machine, the shared computing environment that all Ethereum nodes run. You would use Solidity if you are building a decentralized application on Ethereum, for example, a token, a marketplace, a voting system, or a financial protocol. The browser-based development environment Remix is the recommended starting point for newcomers. The Solidity compiler is written in C++ and the project is maintained by the Ethereum Foundation. It is open source under the GNU General Public License v3.0.
