Back when I dabbled in bitcoin, one of the coolest things to me was the cryptographically verifiable casinos. To explain simply, the hash of each day’s seeds were published the day before, and the actual seeds posted the day after. So you could verify that your wins and losses were legit.

This could be applied to casinos, but it would take legislation to require it. I doubt any casino, especially the ones in sovereign Native American lands would voluntarily adopt such a system.
