The Forecast Foundation's operations lead, Tom Kysar, told CoinDesk:
"Essentially, we are going to launch Augur with one market, and that market is: 'Will Augur be hacked?' or 'Will there be a critical vulnerability discovered in Augur' by a certain date?'"
If you bet "Yes, Augur will be hacked." and Augur hacked, you don't get your money back, would you? Accordingly, without bets on yes, there are no bets on no. If no money in the contract, then why hack it?
