What is UMA?

UMA is an optimistic oracle and dispute arbitration system that securely allows for arbitrary types of data to be brought on-chain. UMA’s oracle system provides data for projects including a cross-chain bridge, insurance protocols, custom derivatives and prediction markets. UMA’s oracle is used to create many other types of products and protocols.

How does UMA work?

UMA’s Optimistic Oracle allows contracts to quickly request and receive price information. The Optimistic Oracle acts as a generalized escalation game between contracts that initiate a price request and UMA’s dispute resolution system known as the Data Verification Mechanism (DVM).

Unless they are contested, prices suggested by the Optimistic Oracle won’t be conveyed to the DVM. This makes it possible for contracts to acquire pricing information within any time frame that has been specified, without the necessity for an asset’s price to be recorded on-chain.  

If a dispute is raised, a request is sent to the DVM. All contracts built on UMA use the DVM as a backstop to resolve disputes. Disputes sent to the DVM will be resolved 48 hours after UMA token holders vote on the price of the asset at a given time.
