A middleware component or network within decentralized systems responsible for securely delivering external, real-world data to blockchain smart contracts.
Mechanism
Oracles fetch information from off-chain sources, such as price feeds, event outcomes, or weather data, validate its accuracy and authenticity, and then broadcast it onto the blockchain for smart contract consumption. This process bridges the on-chain and off-chain environments.
Methodology
Decentralized oracle networks employ cryptoeconomic security mechanisms, including staking and reputation systems, to ensure data integrity and resistance to manipulation. This enables smart contracts to interact reliably with external information, supporting complex decentralized applications.
