Smart contracts need real‑world data. Oracles deliver price feeds, weather, supply‑chain info, and randomness to chains, powering DeFi protocols like lending, derivatives, and insurance. Decentralized networks (Chainlink, Band, Tellor) aggregate signals, use reputation, and on‑chain settlement to cut manipulation risk. Reliable oracles are the backbone of trustable DeFi.
