Oracles are the unsung heroes of smart contracts and DeFi, bridging the gap between the blockchain world and real-world data. Without them, smart contracts would be limited to on-chain data, stifling innovation. Oracles provide essential external data, enabling smart contracts to execute based on real-world conditions—think price feeds for decentralized exchanges or weather data for insurance contracts. Dive into DeFi and smart contract development, and you'll see why oracles are indispensable.
