What is Chainlink?

Question

What is Chainlink?

Accepted Answer

Chainlink is a **decentralized oracle network (DON)** that provides secure and reliable off-chain data and computation to smart contracts across any blockchain, effectively solving the "oracle problem" by acting as the critical middleware that connects the on-chain and off-chain worlds. It enables hybrid smart contracts to securely interact with real-world data, events, and traditional systems, facilitating advanced applications in decentralized finance (DeFi), gaming, and enterprise solutions.
