Ever wonder how DeFi knows the price of Bitcoin when you trade a stablecoin? The answer is an oracle – a bridge between blockchain and the outside world. Oracles feed real‑world data to smart contracts, enabling dynamic pricing, yield farming, insurance payouts, and more. Without secure, reliable oracles, DeFi would be stuck in a sandbox. The challenge? Preventing data manipulation while keeping speed and cost low.
