Does anyone have any idea of a good way to determine truth, kind of algorithm/procedure/protocol for truth(agreed upon belief maybe, possibly involving WoT )

My idea and why I need something like this, is to have a nostr power prediction market app. On other such sites the truth(I believe) is determined and set by a central authority.
