UMA's optimistic oracle is a system that settles a question by accepting a proposed answer unless someone disputes it in time; disputes go to a vote of UMA token holders.
On Polymarket.com anyone can propose an outcome by posting a bond (typically $750); a 2-hour challenge period follows, and disputed markets can go to a UMA vote [1].
