How Do Oracles Feed External Price Data to Smart Contracts?

Oracles are third-party services that provide smart contracts with verified, real-world data, such as the current market price of collateral assets. They are crucial because blockchains cannot natively access off-chain information.

Oracles aggregate data from multiple sources, sign it cryptographically, and transmit it on-chain, allowing the smart contract to accurately execute functions like liquidation based on the true market price.
