Augur is built directly on Ethereum. Truthcoin will be making its own chain. I don&#x27;t care who wins, and to be honest I don&#x27;t give either a very high chance. I really really think prediction markets should exist though, So I applaud both efforts.<p>One real big problem is nobody wants to bet using shady highly volatile currency like Bitcoin or Ether. I&#x27;d much prefer USD markets, Vitalik has some ideas about making stable coins that track USD. Hopefully that works out.
