That article, also says this "
At no time, does this post accuse any casino of cheating."
And the final paragraph:
The analysis presented here examined a specific implementation of a browser-based "Provably Fair" system. Other implementations of this concept will vary from site to site, and may or may not exhibit similar vulnerabilities. Non-browser based implementations of Provably Fair (such as SatoshiDice) do not exhibit these weaknesses and are not the focus of this analysis.
Of which I can say, that if you as the player, check the numbers and seeds before you click on "Roll" or "Bet" or "Deal", you will have the same provably fair system as the non-browser based implementations.
That said, now that the analysis has been released, I would agree that if your casino carried out any attacks, the damage to your reputation would be extreme.
Then the author continues to comment further:
On most browsers, you are able to examine network data passing between the client and server, so it is possible to see the partials, but detecting them might be another matter (more on that when I grab a free tutorial).
Yes, I agree, it is definitely possible to implement a provably fair game in a browser.
As long as one scrupulous person can run a few tests and definitively prove that the site is cheating, then the entire casino becomes invalid and all customers will leave.
If you can set the client seed, AFTER you have recorded and seen the server seeds, and verify that it was not suggested or changed at any point while you are playing, what can get more fair than that?
It is not fair to accuse any site of being unfair when you have no proof at all, especially when they provide you all the tools you need to verify the fairness of the game. Gut feel and beliefs, (this is not religion) are irrelevant when you are faced with math. 2 + 2 = 4. That can never change.
