Yeah, actually that is true. Enigma worths mentioning as one of MPC references.

Looks like Enigma would have challenges in many practical environments (mainly because it involves a lot of small interactions between nodes, so should be affected by latency). So, it's more like a way to build "Etherium of private computations".

But, as you pointed out, it can have good clues how to solve the problem of active adversaries!
