Based on my comprehension, I found the thread pointing unspecific on what he really wanted to achieve. I don't really see if the OP is pertaining to lottery systems that either uses cryptocurrency as their fiat (in which uses blockchain technology as well) or is he talking about making a lottery system that uses blockchain as it's back-end technology. If he talks about crypto's blockchain, then maybe your vipgame.io is his best option. And if he wanted the back-end blockchain, I think Cryptolotto fits the category.

Nevertheless, getting ideas from others without specifying your whole plans or goals to achieve, you might find comments that are either unnecessary or off-topic with what you really intended.
