Reputation (REPv2) is a token used on the Augur platform, which is a decentralized prediction market protocol built on the Ethereum blockchain. It serves as a reputation token, representing the value of a user's activity and accuracy in reporting outcomes of events. Augur was founded in 2014 by Joey Krug and Jack Peterson. The name "Augur" comes from the ancient Roman title for a professional diviner or seer.
