I suspect this doesn’t generalize in any useful way. SOME beliefs have partial-evidence that can be shared, or correlated evidence (including proof-of-belief) that can be shared. Very few are amenable to an un-gamable mapping from math to experience. It’ll be very specific to the belief and the evidence.
Wagers and prediction markets are good examples of proof-of-belief. Y doesn’t have to trust X on this topic (but does have to meta-trust X that the wager is real). And the more participants, the less trust required in any given participant.
