Competition Enigma

Enigma like us uses the notion of multiparty computation, and uses Intel SGX to run the private encrypted computations in a market-selected trusted worker. The final outcome of the computation is necessarily more expensive than if done privately on a state channel; so it's only interesting if you can trust the platform to run computations privately, that would be quite expensive if done with homomorphic encryption, that you don't care if the NSA sees. (They also don't have End-Point Projection.) But if your application fits their slightly weird security model, it could be somewhat interesting. Not a general solution to actual issues of DApp developers.
