Augur
Augur is an Ethereum-based DeFi (Decentralized Finance) prediction market where users can participate in the outcome of several events, including election results and sports.
Founded by Jack Peterson and Joey Krug in 2014, Augur is a decentralized and P2P (Peer-to-Peer) prediction market protocol built on Ethereum, allowing users to create markets around the outcomes of real-world events. The protocol in itself is a compilation of immutable contracts existing on the Ethereum blockchain. Its native token, Augur Reputation (REP), is an ERC20 token that helps to report the prediction market outcomes.
