Fortunejack's "provably fair" system is insecure

[BitwiseOperator]

It does not disclose the next server seed hash until after you send your next client seed to the server.  So it's possible that the server seed is being generated AFTER the server already knows your client seed, which makes the provably fair system completely insecure and useless.

You are right!

For those who don't have an account there and still want to understand the problem: could you offer some more details? Like some screenshots etc which document / illustrate the problem?

Thanks!
