Tag Archives: Provably Fair

If you have been to a number of bitcoin gambling sites, you likely have encountered the phrase “provably fair” at least once. Many bitcoin gambling sites use the phrase for promotion. They seem to have this urge to emphasize that they are a “provably fair bitcoin casino” not only through the text on their homepage but also through a seal or stamp placed alongside other seals that supposedly indicate the site’s reliability and trustworthiness.

Provably Fair gambling

But what does it mean to be a provably fair bitcoin casino? Why do bitcoin gambling sites have to be promoted as such? The answer is simple. It’s because the phrase means that the casino can be trusted in being fair, in not cheating its players. You should get the idea of what it means by simply dissecting the two words in it. There’s nothing really technical in this phrase. “Fair,” of course is already self-explanatory. “Provably,” on the other hand, is an adverb which means “in an obvious or provable manner.” To be provable means to be capable of being proved or demonstrated. It means that the claim of an online gambling site in being free from cheating can be proven.

But how does it work? How can you prove that an online casino is not really cheating? There are several methods to do this but for this discussion, we will only present the most basic implementation. This basic implementation involves the use of a serverseed, clientseed, and nonce. All these three variables are used to calculate the game results.

  • The serverseed will be provided to you (by the online casino) as an encrypted hash although it may not always be hashed so you may have to use an online tool to be able to generate the SHA256 hash of the serverseed.
  • The clientseed is generated by the browser you are using. However, to make the test more reliable, it is advisable that you modify this clientseed. You may add or replace characters.
  • The nonce is a number that starts from 0 or 1, depending on the online casino. It serves as the order of results or the bet number.

You will be using these variables in an online form usually provided by the online casino like the one shown below:

To verify, you just have to compare the RESULT generated by this tool with the actual results of the game. The resulting numbers should match 100%. For example, in the sample result table for a dice game below, the RESULT should be 79.69 for nonce 0, 61.18 for nonce 1, 74.44 for nonce 2, and 27.76 for nonce 3.

Provably Fair test results

As mentioned, there are different methods for doing the test. Some may use variables such as the server salt or server secret. Information about these methods are usually provided on the site to help the user. The method discussed here is simply to provide an overview of how it works. Basically, the idea is that game results should not be affected by inputs from the online casino or third parties.
