2-Party Multi-Party Computation (MPC) · interactive walkthrough
Find what you have in common —

They want to collaborate
Two parties believe they share customers and want to act on it together.

No one to trust
Not each other, not a vendor in the middle. The answer must come from cryptography alone.
