01 / Server Seed
You won't be able to see the server seed when you open a case or carry out an upgrade, but you will be able to see it after the session. This is necessary for the sake of security.
SKINROLL / PROVABLY FAIR
PROVABLY FAIR
Provably Fair or PF is an algorithm used by Skinroll to prove that all results of randomness-seed-generation on our case opening site are equally arbitrary. You can be sure that there are no ways to manipulate the systems and that all users have the same probability of receiving an expensive item.
02 / Client Seed
The Provably Fair validation mechanism depends on the server seed, client seed, and Nonce. These parameters create Roll, which is used to define the result.
03 / Nonce
Complete transparency and fairness of the PF system are achieved through a special random seed generation algorithm.
Here's a quick explanation of how the PF algorithm works on Skinroll:
Complete transparency and fairness of the PF system are achieved through a special random seed generation algorithm.
Public Hash
HMAC_SHA256(key = secretSalt, message = serverSeed) Client Seed + Nonce
rollHash = HMAC_SHA512(key = clientSeed + "-" + nonce, message = serverSeed) ROLL
roll = (int(rollHash[0:15], 16) % 100000) + 1 The public hash commits to the server seed before the session. The server seed is hidden while the seed is active and becomes visible after the session ends or the seed is rotated.
On Skinroll you can:
- Check the history of math seed generation and case prices. This makes it impossible to customize the hit probability for particular users.
- Check other users' hits and other players' game results. This means that other players' game results couldn't have been falsified.
- Check the history of the client and server seeds. The data can be verified by anyone at any time.
Check Roll
We are confident that we have one of the most transparent and honest PF systems on the market.
