The most interesting idea associated with blockchain have nothing to do with money. It’s ideas like this that really grab me. I fiddled with Klout when it first came out but quickly decided I didn’t care much about my ‘influence’ score. But it would be cool to have a high Rep score.

Here’s how it works: After one group of people joins a prediction market and bets on an outcome, Augur pays others to identify that outcome—to verify what happened. But it doesn’t just pay them a flat fee. On its blockchain, Augur houses its own cryptocurrency, a digital token that encourages people to get things right. “If you’re not telling the truth, you stand to lose a bunch of money,” Krug says.

Augur calls its digital token the Rep. This cryptocurrency doesn’t let you buy and sell stuff. It tracks your reputation—that is, how often you tell the truth. People bet their Rep tokens that they are indeed telling the truth—reporting the facts as they actually are. If most others agree, the system returns their tokens and pays them in cash.
