I come up with idea to build a dice machine that will mix the dice and have video camera broadcasting, so people would see that.
You think that would work?
If you mean designing an online casino with a dice-mixing machine and real-time video feed, then no, I do not think that would work.
While an online casino with a dice mixer and live video could seem more transparent, it unfortunately would not guarantee fair odds. Even with random rolls and real-time footage, there would still be ways to game the system behind hte doors. For fairness wed need more than just uncensored footage of the roll. A site would have to open their whole operation to audits and oversight from stem to stern. And even then, risk always looms when money is on the line.
