Guys, what's the default machanism to detect what is true and what is false by rabdom validators, how it works?
For example bets or any other actions which require approvement.
I read something, the main idea is that people place theur money on their verdict if it's wrong then validator lose money, but if validators cooperating or the top stack validator cheats how to solve it?
Should be trivial problem for defi

Do you mean something like a prediction system where at the event the result is based on a real event (like a soccer match) and validators are like in a pool but randomly selected to verify an event? Or how do you mean that with an example?

Yes

Difficult. You always have to have one source you trust. Like let's say you place a bet saying the next soccer match ends in favor of team A. 50% of the users place a bet for A, 50% for B. Now team A wins against B. But the users of B punish you, just so they don't lose. What do you do?

If you plan to do this decentralized, my idea would be maybe making an option to mark a result as wrong. And if 51% of both sides vote for that, everyone can claim their bet back plus the bet creator gets some tokens burned or so. Like let's take my example, now all users of B want to punish you, but since A won, noone of A does. However, let's say you enter B as a winner even tho A won. Now you'd have to have some honest A bettors who claim a wrong result and if 51% of the A bets agree on that, all bets get released and you get tokens burned you have to placed up as a security. Something like that.

I thought about 3rd party who gets percent for validation

I know, that's in my case the bet creator. It doesn't matter, in every case you have to trust someone/something.

from one whitepaper. I don't clearly understand what are these rounds and what's happening there. I see that if someone not agree with that then he pays like fine for public reporting and then anyone can report his outcome, but how they will know the truth? If I have like a lot of money and I will put it all on false outcome or something
