Oracle Price Feeds are external data sources that supply real-world asset prices to decentralized applications (dApps) and smart contracts on blockchain networks. They bridge the information gap between off-chain markets and on-chain protocols, enabling accurate valuation and settlement for crypto financial products.
Mechanism
A decentralized oracle network collects price data from multiple reliable off-chain sources, aggregates and validates it, and then transmits the verified price to a smart contract on the blockchain. This process often involves economic incentives and cryptographic attestations to ensure data integrity and resistance to manipulation.
Methodology
The methodology for secure oracle price feeds relies on redundancy, decentralization, and reputation systems for data providers. This mitigates single points of failure and enhances censorship resistance, ensuring that on-chain protocols receive robust, timely, and tamper-proof price information essential for collateral valuation, liquidation events, and derivative settlements.
