## Multi-Source Data Aggregation Risks

Multi-source data aggregation risks refer to the vulnerabilities that arise when a protocol combines data from multiple oracles to determine a final asset price. While this approach is designed to increase security, it can introduce new failure modes if the aggregation logic is flawed or if the underlying sources are correlated.

For example, if all aggregated sources rely on the same primary exchange, a failure at that exchange renders the entire multi-source system vulnerable. Additionally, attackers can attempt to manipulate a subset of the sources to bias the final aggregated result, especially if the protocol uses a simple mean rather than a median or trimmed average.

These risks highlight the importance of source diversity and the need for sophisticated algorithms that can detect and ignore malicious or erroneous data inputs. Properly designed aggregation systems are essential for the integrity of derivative markets that require accurate and timely pricing.

Failure to manage these risks can lead to catastrophic losses during market volatility.
