Oracles in the context of blockchain technology are external data sources that provide smart contracts with real-world information. Smart contracts on a blockchain are self-executing and deterministic, but they lack the ability to access data beyond the blockchain itself. Oracles bridge this gap by feeding external data, such as stock prices, weather conditions, or sports scores, into the blockchain, enabling smart contracts to react to real-world events. Oracles play a crucial role in decentralized applications (DApps) and DeFi protocols, where accurate and timely data is essential. Understanding the function and reliability of oracles is vital for developers and users of blockchain-based applications.
