Am no expert, so don't quote me on this,  but as far as I know to understand, and eventually verify, what method has been used to those SHA512 hashes you need to know client seed, server seed and nounce: client seed and server seed are concatenated together with the nounce and are hashed by the SHA512 algorithm to form that data strings you provided.
To gather some help you should provide some more infos on those games.




Yes these hashes are the actual final strings where the result is calculated from. There are different methods to use such as this which is commonly used by most companies like Aviator, BustaBit, SpaceX,Bitsler etc.Stake.com uses it too but with first 8 characters not 13;

Example 1;

SHA512 hash="3f3da73e3d30f5791c628ae61d236744304efdbd51ba3e2505588fa76f466dd41e201a3acfdac47 e1a08fb9be9a5240eeda3c0e1fddab92d2d30523e90df3dab"
-Take the first 13 characters (3f3da73e3d30f) and convert it from a hexadecimal to decimal (1112544502862607)

-Divide it by pow(2, 52) to get a number between 0-1 (1112544502862607 / 4503599627370496 = 0.24703450459964293)

-Calculate the payout with the formula: floor(98 / (1 - 0.24703450459964293)) / 100 = 1.3 and max cap it to 1,000,000 to get your final bet result: 1.3x;



Above method is most common but there are other several methods available

If you apply this method to the strings i provided you won't get those exact results i provided;
So i need more methods to try and go through them to get the exact one that was used

Hello, does anyone know a provable fair method that was used to generate these multiplier  results from SHA512 hash?

Result 30540x from SHA512 hash ="2440f86737213d5a5f16589defbba34dc58f93abc91475d890fcf5520a1c9000f05ee7d796efe28 0316ac24d42d544861230de2aea6744e860528fa839bf6e3d";
      Result 19029x from SHA512 hash="079093b03b6ed934ded20619ac1fb9dcf6ec544a1780bacc118fe9a1a928c82e1885bcbb775e3e6 73a137c25fb05f9b1683a3a0b33d91c84671f34d8e82d418d";
      Result 17315x from SHA512 hash ="fbdd75cfae6f59bd0d5750bea193df8abf7e943bdd088865597adc2777d2a146dafdd974dd1d8ab 7434afedf3661793ccbcb6467787ec731d6856f8abad48144";
Result:
1980.62x from SHA512 hash=
"509b48b815b89fcfca21923d426855bd9a4a550181eb3ea46ddb9bc9bb6a078e3ddc00b62b922c5 fd99c9d9fad1fd38771a1bba36bbb24b1c2798adf1374b2b6"

I tried the method used in Aviator game but it didn't work. Looks like a different method us used here to generate round result from SHA512 hash.

Does anyone know a different method to solve this???
All suggestions are appreciated. Thanks!!
