By the way, learn about double spending, before someone runs off with your entire wallet. I bet you haven't modified bitcoin.conf to prevent trivial double spending attacks. There's a reason why the biggest bitcoin gambling game now pretty much requires 1 confirms, and it is for a good reason - because you'd be losing money otherwise when you get large enough.

Thank you for your concern.

This is why we only pay out if we have three confirmations. But you can play with zero.

Also, widely used hashing algorithms are not an "unknown algorithm". hashes are the core of bitcoin.
Yes and this is good so. But does not have much to do with the distribution of its random numbers.


"Provably Fairness for Dummies"

1. casino generates a random string, called the 'secret'. Use whatever random system you're using now.
2. hash("sha256", $secret). Show it to the player.
3. player provides their own secret, via txid, or normal input. Generate player's secret by collecting mouse movement. Let player specify their own secret.
4. output = hash("sha256", $casinoSecret . $playerSecret)

Of course you are underlining the advantages of "provably fairness" as you self advert for such a casino. But the problem lies in the $playerSecret. A hash calculated on the clients computer does not provide as much proof as you tell. It can be manipulated too. To exclude that you have to make statistics too what needs the same amount like every statistical proof else. As long as such a "provably fairness" isn't certified by a trusted 3rd party it's not so "provable" as it seems for an customer.

If the hash $playerSecret comes from a 3rd party like the bitcoin network it is a legit process to use this to make a gambling service provably fair. But as long as the $playersecret is generated by some shady javascript on the casino website the "provably fair" is not as proved as you say.

Yes we could implement a "provably fair" algorithm, but it only would suggest the user a security he can't have. So we decided that the user should decide on realistic parameter if he wants to trust us or not.

The user should always be aware to get cheated on the internet. And we don't want to lull our customers into a false sense of security with algorithms which only look good.

Well we have discussed the provably fair topic for a long time, during the development process. And we concluded that the only real proof is to make statistics with the transactions log. Everybody who knows statistic will very quick recognize if something is not fair on the casino.

As we don't have a payment for every bet we can't use hashes from transactions to generate random numbers.

We studied the „provably fair“ solutions on the Internet which came without such a transaction hash. Normally there are some hashes generated on the server and some on the client. Those calculate in a known algorithm and a huge documentation of all calculations give some feeling of proof.

Everybody who tried to generate a random number with a mathematical formula knows the challenge. In fact it is not possible. To generate a random number you need the most unpredictable event as possible what contradicts with the philosophy of math to predict everything. So we normally trigger physical events like the memory or CPU usage to make the random number less predictable.

To get the most unpredictable random number for diceeno.com we have implemented a hardware application which measures the noise on a Diode junction. With that we initialize our random generator. This gives us a very realistic distribution of random numbers. The prove of that lies in making statistics.

We won't give the feeling of a proved security because this just does not exists. The only proof that a casino is fair lies in the played games. And we hope that the users make their statistics while playing and check the fairness of every casino they use and don't just believe in some white papers distributed by the casino owner never certified by a third instance.

Due we faced much more traffic than we expected, the server crashed. A hardware upgrade is on its way.

The user gets a log with all his transactions. The statistic will prove that it is fair.

I think in the near future bitcoin will mainly be used for internet services and not for real world products. The price is currently much too unstable to fit the needs of a currency.

The price of a product has to depend on the request of the product not on the request of the currency.
