Yes, gambling sites provide us with server seeds that can be verified.

But how do we really know that these seeds are used in actual gambling process?

Isnt it possible they are just displaying server seeds and hashes that we can verify but in reality the server seeds they are using in the back-end functions of the game are actually different/rigged?

Hi,

If they have explained 100% how their provably fair works then u can check it at any time and it is too risky for them to manipulate with it. BUT i have seen personally some casinos who DO NOT post all info about how their results are calculating so there are bitcoin gambling sites who can use FAKE provably fair.

You should be a smart person to understand how the result is calculating as there are VERY complicated provably fair mechanisms.

Be patient! Wink

Exactly, you need to know how to verify it.

BTT: in past I have tried to explain the principle and was quite good response about ... see:

I can explain it on simple example, (just the principle)

BTCRock - it's game where you have a grid 20x20 and you have 6 attempts to find gold vein.

Their proof is that immediately after solving captcha you can see hash of "gold vein coordinates ".

After you made your 6 tries, a result is shown to you:

Proof is that from begining the coordinates gold vein was [11,9], and was not moved if you luckily hit it ( it would change the hash)

You can check it using: http://www.xorbin.com/tools/sha256-hash-calculator

1 - enter: 65879c50984f5b9ede009960e6efa3c6|[11,9] (proof of location, shown after game end)
2 - hash it (using sha2586)
3 - you'll get: c0344a8d187371c671d9e16cb27190a74caef8fe32ab66be7287ed050fca2b12 (this is what you know from begining)

tip: for clarity try to change one coordinate and hash it again, will see you got completely different hash.

P.S. This's only principle, and can be used in various way. You should check description on particular site.
