HI,

i've made these three bets:

Two wins and one lose.
I never receive the winnings nor the fee of the lose.

What's going on ? It's the site a scam?!!

Sorry, must have missed that question, apparently the watchlist doesn't quite work like I would expect.  Anyway it does seem that transaction went through, may have just been a little slow at the time, I have been working on some updates.

And on that subject I believe at this point it's been tested well enough to make public knowledge so without further ado I present the affiliate program.

I have set it up so you can start out fairly simple but have all the data available in easily readable format if you want to do more with it.  It is LTC only right now, but you'll notice I do have a currency selector there and it should be fairly simple to add other similar cryptocurrencies if there is the demand for it.  As an example I have setup LfL1P8SkdFA7WSacf647rkWcj45kbqmb87 which has a 50% chance of winning and pays out 1.92x (the same 3% house edge as the rest of the games) but it is setup with the donation address of the litecointalk forums as the affiliate.  This pays 1% of the total bets placed (regardless of win/loss) to that address.  It has its own stats page at http://greenishblue.info/litedice/LfL1P8SkdFA7WSacf647rkWcj45kbqmb87.html and in JSON format at http://greenishblue.info/litedice/LfL1P8SkdFA7WSacf647rkWcj45kbqmb87.js.  I think the basics are relatively self-explanatory, but I don't exactly have a manual or FAQ or anything for it yet so go ahead and ask any questions and I'll try and come up with answers.

I was playing around with the Litecoin source and used LiteDice to send a test transaction. However I don't see the bet on the site, I'm not sure I messed up my Litecoin source or your site is just lagging. Could you check if you go the tx on your end? (898ccc7e5450858dc3d5576be40d35750574efcf48a026041d3ff36c778f4f8a)

Figured it was something simple, site was updating, was just curious how it was managing a backlog, all came out in the end.

Yeah, looks like someone had a winning streak and it ran short on change txs with enough confirmations to resend.  Everything is paid out now but it is a little short on coins so max bets are low, will get it more as soon as I can move them through an exchange.

wallet out of coins? been a bit since I won the last two and no response or coins in yet.

The backend uses a couple methods to make double spend attacks more difficult.  It maintains connections to a number of peers and checks that incoming transactions have propagated to a majority of them (without forward them itself) before accepting them.  It also uses a separate connection (which does not accept incoming connections) from the receiving connections for sending new transactions out to make the listening connections harder to identify.

For this application the return transaction is also the fastest feedback mechanism (as the web page listing is delayed by ~60 seconds due to the caching) and it will not propagate through the network faster than the original transaction (since any nodes that get it first will not pass it on without the other).  So basically any bets that are processed should be well distributed through the network before any attacker got the results to determine whether to try and invalidate the bet.  Obviously it's not perfect but should be enough to drive the risk up for any would-be attacker to beyond the expected rewards.

LiteDice is very cool! Would you consider releasing the source code? I'd like to set up an altcoin version using some of the coins I'm collecting via merged-mining but don't actually care about losing - for example, IxCoin. It would be a lot more fun to gamble with it then just selling for satoshis on the exchanges.

How does it stop double spend?

The script does automatically update the max bets based on the available balance to make sure that it has enough to pay out winning bets.  You must have caught it right after they got pushed down because of the other win.  Perhaps I'll have to add a little extra leeway there for when that happens, the calculation is conservative enough that a couple minutes shouldn't matter but will let any bets through from people who started when the limits were higher.

I checked when I woke this morning and I did get my big winning

On a side note, I noticed you lowered the max bets on the 512 game and 1000 games so the house doesn't lose as much money if someone wins.

I think you forgot to update the max bets for the under 2000 and under 4000 games, I played all those with max bets and it wouldn't take it being it was too large. I ended up reducing the amount a few times until finally they took.

I lossed an extra 25 LTC to you this morning, so that 416 LTC winnings will be trickling back in.

You should advertise this on the Litecoin forums ^^

Ah I see, my bad !

Yeah, I see around 40 bets queued up waiting for payout now but it'll catch back up shortly, the big win triggered a manual review on the payment backend, guess I should make it so that doesn't hold up the other payments in the queue.

Yes it should return winnings with 0 confirmations when it manages to respond fast enough (these Litecoin blocks come pretty fast) which is relatively safe because it uses the original tx in the payout, so if it ends up voided somehow the payout will as well.

And yes the tx fee can take a fairly large chunk percentage-wise at small amounts.  I don't necessarily want to make the min bet too large, but on very small bets it's way more than the house edge so can't afford to take it out of the house side either without a negative expected return (which isn't particularly sustainable).

I got my payout.....

But 0.16216 payout on a winning 0.20 bet is still wrong !!!!

Waiting on payout on:

Uhmmm.... this is a nice house-edge:

2012-08-01 11:11:49   f2d09d1c3fcc6595...   Under 48000   16827   WIN   0.20000000 LTC   0.16216000 LTC

Shouldn't that be 0.2616 LTC

Now I win and get back less than I gambled !!!
