How Do Multiple Data Sources Help an Oracle Resist a Low-Liquidity DEX Attack?

By aggregating data from multiple, diverse sources, a decentralized oracle network can identify and disregard anomalous price spikes from a single, low-liquidity source. If an attacker manipulates one DEX, the reported price from that single source will be a massive outlier compared to the average price from all other reputable sources.

The aggregation mechanism can filter out or weigh down the outlier, ensuring the final reported price remains accurate and stable.
