People also ask about UMA
Who are UMA’s founders?
UMA was established in 2018 by Allison Lu and Hart Lambur, both former Goldman Sachs traders, aiming to create a global market system that is fair, accessible, secure, and decentralized. Drawing from traditional finance derivatives, they developed an open-source protocol that allows anyone to design and build trustless financial contracts.
What makes UMA unique?
UMA's key innovation is its optimistic oracle, which operates on a 'true unless disputed' basis. Unlike price-feed oracles that stream data instantly, this design allows for human input through tokenholder voting to resolve disputes. This approach is particularly useful for Web3 projects needing arbitrary data that can't be easily coded. The concept has evolved since Vitalik's initial proposal in 2014, and UMA's implementation provides flexible dispute resolution with human judgment.
How many UMA tokens are in circulation?
As of September 2022, the total supply was 108,858,567 UMA tokens, with 68,947,415 in circulation. The token has been listed on major exchanges for several years. It serves as an economic guarantee for protocols using UMA's oracle, with holders acting as voters in dispute resolutions. Token holders also participate in governance decisions and can earn rewards for accurate voting.
How is UMA’s optimistic oracle secured?
The system involves three parties: the data requester, the proposer, and potential disputants. If a dispute arises, UMA token holders vote within 48 hours. Correct disputants receive a portion of the proposer's deposit, while incorrect ones lose their deposit partially to the proposer. Voting occurs in three phases: open voting, reveal, and reward claiming. Smart contracts have been audited by OpenZeppelin, and token holders can participate via compatible wallets like Metamask, Trezor, or Ledger.
Where can you buy UMA?
UMA tokens are available for purchase on major centralized exchanges such as Binance and Coinbase, as well as decentralized exchanges like SushiSwap and Uniswap.
What is UMA?
UMA is a blockchain protocol established in 2018 by Allison Lu and Hart Lambur, both former Goldman Sachs traders. Its stated goal is to create a more fair, accessible, secure, and decentralized global market system. The project draws on concepts from traditional finance derivatives to offer an open-source platform where users can design and build trustless financial contracts.
Central to UMA is its optimistic oracle, a mechanism that facilitates communication between external data and on-chain environments without requiring trust. This oracle operates on a "true unless disputed" model, where anyone can propose an answer to a data request, and it is accepted unless challenged during a verification period. Disputes are resolved by UMA token holders through a voting process, which allows for human input on complex or arbitrary questions that cannot be easily coded.
