Data Aggregation Methodologies
Data aggregation methodologies are the statistical techniques used by oracles to combine prices from multiple sources into a single, authoritative value. These methods are designed to filter out noise, outliers, and malicious data points that could compromise the integrity of the price feed.
Common techniques include calculating the median of multiple exchange prices, volume-weighted averages, or using reputation-based weighting for different data sources. By aggregating data, the system becomes more resilient to individual exchange failures or flash-crash events.
Choosing the right methodology is a trade-off between speed, cost, and security, as more complex aggregations may require more gas and increase the latency of the feed.
