Thats completely different point. The idea was exactly to make:
1. Provable and verifiable unbiased algorithm the does pure random winner selection.
2. Provable and verifiable payout mechanism.
So having that implemented, I wonder what would be the customer acquisition costs? Does it require licensing if whole logic is placed within a smart contract.
It probably won't last long. If, just if, you manage to successfully implement your idea, most would probably participate because of its innovativeness, but other than that, I doubt they'd actually last for you to actually make a profit. Other than that, others have already managed to try it, so the question is, how would you actually attract customers? It's not a matter of your system actually working and being fair since that's a given before you even start, but rather about how you would actually make your customers stay.
You should probably concentrate on actually making your lottery unique compared to others. Only then would it have any attractive value for players to actually play on. That is, on the grounds of your lottery being transparent on how it's winners are chosen as well as its fairness.
