Oracle Aggregation Strategy

An Oracle Aggregation Strategy is the method by which a protocol combines price data from multiple disparate sources to produce a single, reliable reference price. This is critical in decentralized finance, where a single data source can be compromised or manipulated.

Strategies include medianization, where the median value of multiple independent feeds is taken to ignore extreme outliers, or weighted averaging based on the volume or reliability of each source. By diversifying the inputs, the protocol ensures that the settlement price remains accurate even if one or more sources fail or report incorrect data.

This strategy is essential for the integrity of derivative protocols that require high-precision data for margin calls and expiration handling. It acts as a defense-in-depth layer against adversarial behavior in the market.

The complexity of the strategy depends on the asset liquidity and the potential for manipulation on various trading venues. Effective aggregation requires continuous monitoring and updates to the list of trusted data providers.

It is a key element of the protocol physics that maintains market trust.
