provably fair games are okay as it is. They don't need to be improved upon or whatever. They basically speak for themselves even lol. While I think your idea is great and could see some use in the future once gambling becomes larger, I don't think the problem of "cheating" or whatever is a large-scale problem really. After all it's already randomized as it could get. Plus you could basically have it verify its validity. I think it all boils down on "fixing what doesn't need to be fixed". Provably fair is great as it is so I don't think this improvement is needed. Although with your skills, you're definitely going to come up with an awesome idea with real-life application that people will ponder upon for years to come. Keep at it brother.
If OP had an epiphany and came up with some unique method for checking provable honesty, then it should first be published in academic and scientific publications that have a mathematical or unitary cryptographic direction. And at the same time, of course, retaining th authorship and rights to this discovery. These actions, in the case of a truly ingenious nature of the invention of the algorithm, should be discussed and confirmed in the scientific community of specialists. Further development of the idea is only possible if the scientific community truly confirms its uniqueness and accuracy. And also the possibility of correct use in casino practice, as an algorithm for confirming provable honesty. I consider all other actions of OP to promote his invention in such a primitive way to be somehow naive and too simple.
Therefore, I think no self-respecting casino would be interested in an invention that is advertised by OP in this way.
