If you want to put up money on your own, that's great.

But the bets you're proposing are hindering the verification. Because if you can't find someone to put up $250k on the other side, that conveniently excuses you from having to prove anything.

I am stating that nobody should put up any money. You should just meet someone (I will volunteer), and prove these items. Then this person can come back and report whether you sufficiently proved your claims to them.

Simple, right?
