Thank you for making the responsible choice.

Whenever you see a site that says they are provably fair, please ask them to prove it. By definition, they should be able to. If they cannot or otherwise avoid the question, assume they are not provably fair and look to steal your money. A great example of this behavior is RitzGrandCasino, who is fond of making new accounts to dodge negative trust, and making all of their topics self moderated.

I don't think this is the solution. It's *a* solution but any position where that person running that site could be bribed would be a bad idea. People just need to understand it more.

Thank you all for your responses.

Hello, a lot of you have probably seen me around here more than once, generally saying something about provable fairness. I've looked into this for a while and the community really needs to understand what it is.

When provably fair was first implemented as an idea, people trusted it because it was backed by sound math. Nowadays when I see provably fair, it seems like it's more of a fake thing used as a selling point for people who don't understand it.

I'm not here to tell anybody how they should implement a provably fair system. Provable fairness is defined in its title in that it is able to prove beyond a doubt that no results are being manipulated by the operator of the service by using strong proven cryptography. It's not something you can add a bunch of random looking numbers to and say "It looks like its random, let's just leave it at that".

I know some of you have PM'd me asking for verifiers for your sites and I'm sorry I haven't gotten back to you, I've been swamped and have had little time for bitcoin things.

That being said, my main point in this thread is we as a community have begun to get lazy with this. There are sites out there that claim to be provably fair but are not. If you look through my trust I'm sure you'll find at least one.

I cannot protect everybody from these sites and people need to learn what constitutes true provable fairness. A couple easy checks could follow something like this:

• What variables are used to create the random roll? (I would say 90% of provably fair systems derive their results directly from a hash of a few things)
• Does the client control at least one of those variables?
• What does the server use as other input to a hash function? Is it something that they can change by a small amount, test to see if the new roll would benefit them and then substitute without the user knowing?

The above is a major point in which many people fail to look at

Again, I'm not here to tell people that they can't gamble where they want. If you win money from any site, congratulations. You may have won money or maybe you were just a part outside the extra few percent the owner manipulates.

Here is a great example of abusing the term provably fair.

So finally I ask everyone here to please, please please please get somebody that knows what they're doing to look over the site for you, and tell you whether or not it's provably fair.

Bitcoin was created so that you could use strong cryptography to secure your money. Why would you go around and say you believe in that money only to use sites that don't use strong cryptography to prove themselves fair when there are so many out there?

Thank you, and please discuss.

The site still isn't provably fair.

You have yet to prove that you cannot manipulate your system, yet I have proven that rolls can be manipulated. It's called "provably fair" because you can prove that it's fair. You have not been able to do so and should not use the term to describe your website.

Please show me strong proof that other sites can generate rolls. If you're so certain, why don't you prove it? You would gain customers from those "untrustworthy" sites.

Gamble at your own risk.

Luckynumber.me is not provably fair, because of the inclusion of time down to the millisecond in the decision of the final roll, this is why.

Say you make a bet at 3:34 PM, 13.23 seconds. The outcome of the roll was a win.

Luckynumber looks at your roll and calculates that it would be a win. So they pretend the server got the message a millisecond later. Let's do a new roll with a new time.

Your bet was now made at 3:34 PM, 13.24 seconds. The outcome of this roll is a loss.

This allows for major roll manipulation. They don't have to do this every bet. They can just do it on larger bets, or once every 20 rolls or so. It doesn't matter if some people win because they still have to keep their image up.

They can also repeat the time process multiple times until they get a losing roll.

You might say that you can see the clock at the bottom of the game and you know exactly when you clicked roll. Did you really? Do you know exactly how long it takes the message to get to the server and for the server to record the time? These are all things that can be used against you.

Gamble carefully.

For the love of god, i've posted this so many times before. They're asking you to trust that they are using a third party to generate numbers. They give you passwords in plaintext emails. They delete replies.


For everyone else, they made a new account to get out of their trust. Add negative trust here. https://bitcointalk.org/index.php?action=trust;u=319107

Is my sig ok?

Not pvp as in minecraft fighting, pvp as in player versus player gambling.

Nobody liked you, you abused the referral system against the rules and you will not be staff on the new server.

Wow, that's one hell of a vanity.

Because you act like PD3 is already out. You're feeding off of hype.
