It is unpleasant to see a typo on a serious site. It is even more unpleasant if this typo makes you nervous.
However, as we saw, the site can't be called a Scam and the hash they have matched.
Perhaps they should have paid more substantial compensation for the error found and the disturbance caused. It's on their conscience.
I'm not sure about that. They are now clearly aware of the so-called typo but they still haven't fixed it...
If an user is unable to check the fairness of the game with the datas provided by the house, it's a scam to call it a provably fair game.
Do you seriously believe that information about another algorithm was specified intentionally and this information will continue to hang there?
They specified an invalid SHA512 algorithm instead of SHA256.
This looks like a typo. Although it does not do honor to such a site.
I rechecked the hash with the SHA256 algorithm and it is really correct:
Meh, in fact it was predictable that all situation will resolve itselfe in such way (though i bet that this was because OP hashed seed as a string)
I am surprised that many people used this site and no one noticed the typo. It turns out that no one checked the hash or people somehow guessed what algorithm to use.
