Multi-party computation (MPC) enables a set of mutually distrusting parties to compute any function on their private inputs. Mainly, MPC facilitates agreement on the function’s output while preserving the secrecy of honest inputs, even against a subset of parties controlled by an adversary.
I can’t tell if this is relevant, but it might be interesting to some.
