Pull Oracle

Algorithm

Pull Oracles represent a deterministic process for retrieving external data, crucial for smart contract execution within decentralized finance (DeFi) ecosystems. These algorithms typically involve querying multiple data sources and employing aggregation functions—such as medianization—to mitigate manipulation risks inherent in centralized data feeds. The selection of appropriate aggregation methodologies directly impacts the robustness of derivative pricing and settlement mechanisms, particularly for perpetual swaps and options. Consequently, the algorithmic design must account for potential outlier data points and ensure data integrity to maintain market stability and prevent systemic risk.
