Hi guys,

As you all know there are a LOT of websites where you can gamble, play games, etc with cryptocurrency. I've been thinking about starting something myself and I think I might have an interesting idea that's not been done yet.

Currently I'm exploring the idea and trying to tackle any issues, and the last issue I'm facing is the issue of fairness. Now, with games like high-low and roll the dice this is relatively straightforward. You can prove a fair game by showing the hash of the game data in advance, so you know the data has not been tampered with.

But how about games like poker, where there is an element of secrecy? Ofcourse you can prove the cards are randomly dealt, but how do you know your cards are really hidden to everyone else? In theory, the maker of the game could know the hand of every player and cheat at his own game. I wouldn't play a game if there's no garantee there's no cheating going on.

Hi there,

Yesterday (around 16 hours ago) I transferred some BTC from the Bitcoin app to my MtGox account. The transaction showed up as "0/unconfirmed". I minimized the app and thought all was well. Some minutes later I tried quitting the app, but it crashed.

Now, I just opened the app and I see the transaction is still listed as "0/unconfirmed". I also haven't received the BTC in my MtGox account. Shouldn't the transaction be confirmed already? Did the crash screw up the transaction somehow? Have I lost my BTC?

Thanks in advance for your help.
