Provably Fair
Provably fair gambling is a process whereby a player can verify that the outcomes of games have been fair in real time.

It makes use of these three technology:
Random Number Generators

• Random number generators generate millions of numbers per second and determine game outcomes.

Seed Generators

• Seed generators create the numbers which are fed into algorithms, which in turn determine outcomes. In provably fair systems, players get to add a seed number, ensuring the casino isn’t in control of the outcome.

Hashing

• Hashing is the transformation of a longer string of data into a shorter string. In the context of provably fair gambling, when a seed number is hashed, it is encrypted. For all practical purposes, the cryptographic hashes used at Bitcoin gambling sites are considered unbreakable. This means you can be sure they haven’t been tampered with.

How does provably fair work?
Although there are several implementations of the provably fair method, we will describe the most common one. With this method each roll-result is calculated by the following variables:

Serverseed - provided by the gambling site

• You will get an encrypted hash of the serverseed before you start gambling. Since you get it in advance, the site cannot change it later. However it is encrypted, so you cannot calculate your own roll results in advance (only afterwards if you get the unhashed serverseed.)

Clientseed - provided by your browser and adjusted by you

• Your browser will generate a random clientseed. However, you could and should adjust this clientseed before you start. This way you can make sure the site does not know your clientseed in advance.

Nonce - A number that increases with each bet you make

• Now if you make a bet the nonce starts with 0 or 1 depending on the website. After each bet you make, the nonce number will go up by 1.
