Oracles fetch external data (e.g., government records, biometrics) and deliver it to blockchains via decentralized networks like Chainlink. They aggregate inputs from multiple trusted sources, ensuring accuracy and tamper resistance. For identity verification, oracles can validate passport details or KYC checks by cross-referencing official databases. Cryptographic proofs and consensus mechanisms secure the data, enabling smart contracts to verify credentials without direct offline checks, thus maintaining decentralization.
