Looks like it was caused by a DoS vulnerability in bitcoin (see the reddit link above) but fortunately it appears that miners are no longer mining (?) the exploiting transactions, so the backlog has cleared up and it should be business as usual.

(I hope the miners have figured out how to identify and remove the exploiting transactions, rather than just the attacker has stopped)

Turns out this was the cause: https://www.reddit.com/r/Bitcoin/comments/3ur5ma/stuck_transactions/cxh9o4x

looks like quite nasty, hopefully there will be some fixes soon :/

New draw is about to start, with only 3 sponsors so if you want to get an ad for cheap, now is the perfect time:

Doing it perfectly in a game like bustabit would be quite challenging, as we have a dynamic house edge (between 0 and ~0.99%). Basically you'd have to wait until everyone bet, then solve for "Point that my loss would be: HOUSE_EDGE_AT_THAT_POINT * MyBankroll" (as equation I'd only know how to solve numerically)  and probably adjust that after each person cashout.

Or you could just estimate the average house edge at ~0.33% and make the make max profit  = 0.33% * bankroll

I think I've explained it already a couple times why on support, but it's because after that transaction was sent a flux of new transactions have come in with higher priority, and backlogged it. I promise you'll get your money, and I even created a conflicting transaction for you with an *extremely* high fees:

There's nothing else I can do, and you just need to be patient, and I promise you'll get your money.

Incidentally, once 0.12 bitcoin comes out, this will be supported much better and won't be a problem.

Basically the "max profit" functions as a stop-limit to the amount of money that bustabit.com can lose in a single game. If the house ever loses this amount of money, everyone is instantly cashed out at that point (enjoying that amount of money)

Great explanation, but I'll make one minor correction: the max profit isn't calculated using the kelly criterion (that's only what sane people use, and what moneypot uses). I'm just using a fixed 3% of the site bankroll, which is probably around ~6-10x the kelly. That said, I'm also under-reporting the site of my "true bankroll", like for instance when recently the whales started raping the site, I kept filling up the bankroll (as I was confident they were legitimate whales, not someone with an exploit)

Sure, but you can just use a fixed salt. Like '-outcome'.



Well your code explicitly redraws if it's 0, so it's actually between 0.01 and 999.99.  Although I don't understand why you don't just generate a number  between 0 and 999.98 then add 0.01

I think I see now, I'll give that a try. Although my immediate questions would be:


How could luckyNumber ever be less than 0?

And:

Wouldn't you be better off just shifting $luckyNumber by 1 spot instead of all that?

Also, the only game I looked at so far (blackace) doesn't seem to be provably fair at all? AFAICT you're only proving the "win multiplier" **if** they win, but rely on us to trust you to tell us if we won or not.

For instance in game #155 I bet 702 bits on the 2nd card, but you claim the correct result was the third card. Now if I use your provably fair, I can tell that had I won I would've got x4 my money, but how can if the real winning card was the 2nd card or the 3rd card?

In fact, I care a lot more about knowing if I was right or wrong, than knowing how much I would have got had I won =)

I now have the money, but it's not showing up in the deposit history. But I can't withdraw it:



even though I've only claimed the faucet once.


Also, locking withdrawals because "faucet abuse" seems rather abusive, once you give people money it should be theirs. If you think they're abusing the faucet, stop giving them more.

It actually has 2 confirmations now:

Looks very nice! I tried sending a bit of money, but it doesn't show up instantly =(

Also it doesn't let me change my client seed:

And this is the first time I've even tried.  The typical advice for gamblers is that they set their own client seed before playing, so putting a restriction like this seems a little excessive and counter productive

but from the OP:


So I guess answer to that question is "On Amazon's Cloud"?  (Or are you implying you own AWS?)

I don't think this is implied at all, as what investors care about is bankroll turn over (* their EV, I guess) rather than absolute commission amounts.


 So far YTD investors would have made a little over 60% by investing in MP, so I think that would have outperformed most sites  (primarily due to its small bankroll)

If you guys wouldn't mind, this conversation is probably more appropriate for PMs as the site is still hasn't sold yet and the auction is still underway.  

The auction process is still on-going, so I think it'll make sense to wait until we have a winner announced instead of speculating. That said, app owners are the life-blood of MP, so I doubt anyone is going to buy the app just to squeeze them.

MoneyPot actually has a service specifically designed for this that makes it completely safe to send bitcoins from coinbase. It's significantly better than trying to send to an intermediate wallet, or anything of the sorts. And unlike a traditional mixer, leaves no evidence of mixing.


Unfortunately I haven't yet solved the problem of how to (safely) send coins to coinbase, although I do have some ideas (but they'll leave traces that the coins were mixed)

You're right that it's an unconventional auction, but I believe it's more of an auction than a sale as there is no fixed price.

As for why I have and will reject bids, MP has tremendous potential to be used for a huge scam, and that's something I would do anything to avoid. Because of the investor system, all a (rich) scammer would have to do is start creating shill whale accounts on the site, and start losing hundreds of bitcoins to investors. To reassure everyone it's real, you'd just have to show solvency and even though this would be a paper-loss, the reality is that a lot more investor money would come in, then go out because of it. Then after it stops growing (or you run out of paper money), the scammer would just shut down the site and keep investors money.

And that's not purely theoretical, I've been contacted already by two people who I believe had bad intentions (and can be traced back to a previous bitcoin scam) one offering a significant more than the highest bidder.

So if you're interested in the site, I'd encourage you to place a bid. If you're buying the site with good intentions, I can't imagine myself knocking back the bid. And the site is strongly looking like it'll sell one-way or another, and at something I would consider a very attractive price =)

I've published a high-performance stretching library (it uses the modified openssl native code) to npm for the node.js users who'd like to verify games quickly:
