UMA is an Optimistic Oracle Built for Web3
An optimistic oracle serves data to smart contracts using a "true unless disputed" escalation game. UMA’s optimistic oracle allows contracts to ask almost any questions and trust the answer, which enables the use of “long tail” data to Web3 protocols
****It is a powerful and foundational piece of infrastructure for Web3.
🌟UMA is a sponsor of Eth San Francisco 4-6th Nov 2022⭐
