Oracles are the critical link between on-chain and off-chain data in smart contracts and DeFi. They ensure that external data like market prices, weather reports, or sports outcomes can be securely and reliably fed into blockchain systems, enabling smart contracts to execute based on real-world events. Without oracles, DeFi's potential to automate and decentralize financial services is severely limited. Understanding their importance is key to grasping the full scope of blockchain innovation.
