Chainlink

Chainlink is a technology that connects smart contracts—self-executing digital agreements on blockchains—with real-world data. Since blockchains can't access external information on their own, Chainlink acts as a secure bridge, bringing in accurate data such as weather reports, financial prices, or sports scores. This ensures that smart contracts can automatically execute based on real-world events, increasing their usefulness across various industries. Think of Chainlink as a reliable translator and courier that securely delivers necessary outside information to blockchain-based programs.
