What is UMA in cryptocurrencies?

UMA (Universal Market Access) in cryptocurrencies is an optimistic oracle that allows you to record any correct information to the blockchain. Oracles are designed to connect the blockchain with the outside world. An optimistic oracle transmits supposedly correct information to the blockchain if there is no disputed data about it. UMA was founded in 2017 by Hart Lambur. UMA ensures the security of markets and smart contracts in the Web3 environment.
