Aggregates price data from 5 independent sources (Binance, Kraken, Coinbase, CeFi indices, and on-chain venues) and publishes a Bayesian-weighted median price update to UMA's Optimistic Oracle contract, then disputes any submitted price >2 standard deviations from this estimate. Disputes cost-neutral due to UMA incentive structure.
