Is there an analogue for this to show that a person must know something even if they pretend they don't?

Say I'm a middle man escrow service with an untrusted channel, and trusted A has sold a secret X to untrusted B using me, and B now wants to sell X to untrusted C on my platform. Is there a ZKP way to both make sure B doesn't scam C by sending a fake secret, and C doesn't scam B by saying they received a fake secret? Obviously while me and snoopers never knowing what X is?
