How Does an Oracle Provide Reliable Price Data for a Decentralized Option?

An oracle is a third-party service that securely fetches real-world data, such as an asset's price, and submits it to the blockchain for smart contract use. For a decentralized option, the oracle provides the reliable, tamper-proof spot price needed to determine if the option is in-the-money and to trigger the automatic settlement at expiration.
