What is Uma? What is it Used for?

UMA (Universal Market Access) is a optimistic oracle on Ethereum.

What is Oracle?

Oracles are an important part of blockchain infrastructure. They facilitate untrusted communication between the outside world and on-chain environments.

They have advanced decentralized finance (DeFi) and many parts of the Blockchain industry, including Web3 applications. (for example: ChainLink, BAND Protocol, API3)

What is an Optimistic Oracle?

Optimistic oracle is an oracle type that provides data flow from the real world to a decentralized environment. Incoming data are voted on with DAOs and accepted as correct if unchallenged.

The optimistic oracle also known as a “a human-powered truth machine” is making global markets universally fair and reliable.

How Does Uma Work?

In UMA’s optimistic oracle, there are three elements: data requester, data provider and potential objector.

Request: Token holders generate Data requests.

Offer: The contract requests data. The offeror pledges a collateral and the data is transferred to blockchain if accepted as correct. Then he regains hiscollateral and they can challenge the data if they think it is wrong during the objection period.

Objection: There can be someone who does not accept the data provided by the offeror and this person pledges a certain amount of collateral and the UMA team resolves the issue within 48 hours. If the objector is right, part of the collateral pledged is given as a reward, but if they are unjust, they lose all the collateral pledged and this fund is given to the offeror.

What Makes Uma Different?

Its optimistic oracle is more flexible than other oracles because of its human-supported system, and erroneous and repetitive data are voted on the DAO and sorted out in agreement. Thanks to its flexible structure, it renders web3‘s potential limitless.
