Decentralized Oracle

A decentralized oracle is a service that feeds real-world data into a blockchain, enabling smart contracts to interact with external information securely and without relying on a single trusted source. Decentralized oracles are crucial for decentralized finance (DeFi) and other blockchain-based applications, as they allow blockchains to access off-chain data, such as market prices, weather conditions, or sports results. By decentralizing data sources, these oracles minimize the risk of manipulation or tampering. Chainlink is the most well-known decentralized oracle network, providing reliable, tamper-resistant data feeds to multiple blockchain ecosystems. Decentralized oracles play a key role in ensuring that smart contracts execute correctly when real-world conditions are met.
