Was a bug on BitDice. In chat: " had a bug, which user tried to exploit, already fixed. no funds has been lost, nor any loss for investors  ... nope, he actually took some hit on himself, which costed me like 0.002 ... so, as i said no loss for investors ... yeah, but all funds are safe, nothing to worry about " I wonder what it was now.. feel somewhat stupid for not finding that  |

I cannot login, is your time again incorrect? (causing 2FA problems.)

I have been working on a new version with more sites for a long time now. I hope/expect to really finish it within some weeks now. It indeed has taken a bit too long, sorry :p .. soon |

You seem to know a lot about the casino's yourself, Where is it documented that Fortunejack fakes volume? Here some more details / links: The FortuneJack faking stats "discussion" started here: " Are the wagered stats of 14+ million BTC on the homepage correct?", they denied having wrong stats a couple times, so I gave a bit more arguments in this post. Finally they acknowledged it was wrong and claimed it was because of some exchange rate bug and offered me a bug bounty in PM (probably to keep me quite - I refused.) I gave some more arguments on why the wrong stats couldn't be caused by an exchange rate bug. They basically just ignored it from there. Few days later they did lower their stats by 28 times but still basically ignored my arguments. |

Were fun times at PRC/BK but can understand the decision. GG. Let us know if you will have another bitcoin project in the future  |

To be honest I was planning to add negative trust already simply because you still claim that your site is provably fair even though it really isn't. Either way, it seems no one should play on your site. |

Uhm my site is correct  I don't use any fixed percentages or something like that. It's all calculated based on your stats. Is your site not assuming we've obtained commission off every BTC ever wagered? Because that's the part in question. The math itself is correct -- the encapsulated period (and thus wagered) for which we've obtained commission is not. No. I get the profit and commission of all apps. Combine all profit, subtract total app commission, subtract investor profit.. leftover is MP "profit". So it doesn't matter if your commission is 0% or 20%.. I don't use that |

Ah ok |

Mm it seems your site has a "no-cache" header for images, JS scripts and stylesheets. For the video poker page that is like 1.2MB.. seems like caching would be good there? (I have pretty bad internet so really notice it lol) |

Why would I try it? The game is not provably fair. That is a fact.
He might run a fair game.. sure. But that is "hopefully trustable fair", not "provably fair".

I agree with NLNico.
Indeed there are trades even in between a second. He already showed it. How do we know the system chose the correct one by the time we placed our bets? Because indeed there is a time stamp but it only shows it by the second and not milliseconds. Therefore, if there are 10 transactions in one second, how do we know that the system did not pick a number that is favorable to the site?
I am confused why you guys want it to be provably fair since it uses the data from the open market which is VERY EASILY verifiable to be provably fair. Just take a bet, and see if the price matches or is close to the market rate for BTC/CNY and you have your evidence. It is literally impossible to verify. Did you read my posts or not really? Even in your post it's not provably fair: " if the price matches or is close to the market rate".. even 1 CNY cent difference would make a completely different result. This "game" is not predicting a price, it's just using the price in the hash generation. |

Sure, probably in next few days.

You cannot use timestamps if you want to be provably fair. There is no fixed timestamp at bitcoin transactions. There can be a 0 - 10 second delay EASILY between when a bitcoin node gets the transaction. You could maliciously change the timestamp to 1,2,3,4.. seconds later to make the player lose. There is no way for the player to verify if you did this. Therefor it's impossible to generate a provably fair outcome with this. I replied to your PM already too: I never really looked into secondstrade. It is possible that some of their games are not provably fair too. LuckyBit uses a correct way to calculate provably fair bet results for on-chain games. They just use a hash of: <tx_id>:<vout_id>:<secret_key> vout_id is the output index, in case of multiple bets in 1 transaction. Secret key is a daily secret, all hashes of future secrets are published already. Then after midnight they release the secret so people can verify the hash and also the bet outcomes. More details on LuckyBit. This could work for your ODD / EVEN game as well. Of course there wouldn't be any relation with the bitcoin price anymore though.

I am not saying you are a scam. I am also not saying that you are cheating. I could believe that you are honest. But provably fair is not about believing or trusting.
Provably fair is a way for the players to verify and prove if they have been cheated or not. On your site, they cannot verify and prove this, because using "timestamp" is unreliable as shown in my previous posts. Therefor the player just has to trust you to be fair.
That is "trust us, we are fair" and not "provably (=you can prove we are) fair".

If our game can say not provably, that btcc.com is not provably too.
but i trust btcc.com. Trust != proof. Besides that, I am not even questioning the data from BTCC. I don't think your wager volume is enough for BTCC to be malicious. I am saying that we have no way to verify at which point YOU get the data from BTCC. It is very easy to say that the transaction was 1-2 seconds earlier or later at your bitcoin node. This would result into completely different results and there would be no way for the player to verify the bet result. You could make the player lose every bet and there would be no way for the player to verify and prove if he was cheated or not. Your site is not provably fair. You should either fix the provably fair method or stop promoting your site as a provably fair site. |

No, what I said is correct. 1. There is no way to verify at which specific point you get the trade data. Just a few milliseconds later, would result into a completly different result. I gave a pretty easy-to-understand example of this. Look at the link you gave me: {"date":"1481768751","price":5435.7,"amount":76,"tid":"107799733"},{"date":"1481768751","price":5435.7,"amount":14,"tid":"107799734"},{"date":"1481768751","price":5435.7,"amount":4,"tid":"107799735"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799736"},{"date":"1481768751","price":5435.7,"amount":2,"tid":"107799737"},{"date":"1481768751","price":5435.7,"amount":71,"tid":"107799738"},{"date":"1481768751","price":5435.7,"amount":333,"tid":"107799739"},{"date":"1481768751","price":5435.7,"amount":508,"tid":"107799740"},{"date":"1481768751","price":5435.7,"amount":43,"tid":"107799741"},{"date":"1481768751","price":5435.7,"amount":36,"tid":"107799742"},{"date":"1481768751","price":5435.7,"amount":8,"tid":"107799743"},{"date":"1481768751","price":5435.7,"amount":1,"tid":"107799744"}, 12 trades in 1 second, all timestamp 1481768751. All of those traders affect the volume (and sometimes the price.) You can pick the volume you like and there is no way for the player to verify it. Therefor it is not provably fair.2. There is no fixed timestamps on transactions. Each node can see a transactions at a different timestamp, because it takes time for the transactions to be relayed through the bitcoin network. |
