Solidity is a statically-typed, high-level programming language designed specifically for developing smart contracts on blockchain platforms, primarily Ethereum. It enables developers to create decentralized applications (dApps) that can automate and enforce agreements for various use cases across different industries. This technical overview delves into the fundamental concepts of Solidity, its relationship with decentralized finance (DeFi), security considerations, best practices, and its potential applications in business.
Introduced in 2014 by Dr. Gavin Wood, Solidity borrows syntax from languages such as JavaScript, Python, and C++, making it relatively accessible for developers with a background in those languages. As a contract-oriented language, Solidity defines how smart contracts communicate, store data, and interact with the Ethereum Virtual Machine (EVM), which processes the operations of decentralized applications.
Smart contracts in Solidity are self-executing contracts where the terms are written directly into code, allowing transactions to proceed without intermediaries. This property not only enhances transparency but also promotes trust among participants in the network. Read our full research on Budget Planning for AI & Blockchain in 2025 here!
