Interesting, but I'm not sure I really understand, how do we proof it's a person and not still the company itself or a bot or someone else, and why does this matter? Sorry in advance for stupid question but I read it through and still don't get how this is proof of person and why important.

Also, how is all games settled? Which mechanism, is that also on chain verifiable? You say it asks all members of the network for the result, why? What if same members also make bets?
