Ninja Prediction

Ninja is an anonymous peer-to-peer decentralized prediction exchange running on top of the Ethereum blockchain. It allows parties to directly bet against each other without going through a central authority or bookmaker. This makes it 100% anonymous, no signs up no downloads required. The management of bets and the settlement of winnings are carried out collectively by the blockchain network, protecting users from any single point of failure. You can also create your own prediction markets.
