Augur is a trustless, decentralized, collective-intelligence prediction market and no-limit betting platform that runs on the Ethereum blockchain. Augur is a blockchain-based protocol that utilises oracles to harness the “Wisdom of Crowds” to securely generate a variety of dynamic event forecasts. Augur provides a vast array of user-created event forecasts, ranging from sporting events to election results and everything in between. Users can bet these markets by purchasing shares of the outcome they believe will be the result. These bettable markets are constructed via smart contracts deployed on the Ethereum blockchain, which automates payouts and prevents these events from being subject to outages, blackouts, and censorship from third-parties. REP is the native token powering the Augur protocol and the distributed oracles that create markets and report event outcomes. The REP token is also used for betting and market resolutions. Users bet on markets by staking their REP on the outcome they deem likely to occur, which is held in the smart contract until resolution.
