The oracle problem: blockchains are deterministic, isolated systems — they cannot natively access external data. A DeFi lending protocol needs to know ETH's current price to calculate collateral ratios. A crop insurance smart contract needs verified weather data. Chainlink's decentralized oracle network provides this critical infrastructure.

How Chainlink Oracles Work
Decentralized Aggregation
Rather than trusting a single data source, Chainlink aggregates data from multiple independent node operators who independently fetch from multiple sources. The median of all reported values is used, making manipulation of the feed require corrupting a large majority of the independent nodes simultaneously — economically prohibitive.
LINK Token Mechanics
Node operators stake LINK tokens as collateral. If they provide incorrect data, their stake is slashed (destroyed). This cryptoeconomic security mechanism aligns node incentives with accuracy. DeFi protocols pay LINK to access oracle feeds, creating sustained demand for the LINK token proportional to the breadth of DeFi adoption.
