Definition
Smart contracts cannot fetch outside information — prices, weather, sports results — by themselves. Chainlink aggregates and verifies data from many nodes and feeds it to contracts. Much of DeFi depends on it for price references.
Key points
- Widely used as the price feed layer for DeFi
- Also provides cross-chain messaging via CCIP
- Node operators stake LINK to back service quality
Watch out for
- · A bad data feed can cascade into every protocol that relies on it
- · Competition from other oracle providers
