Metadice is now up for sale: https://bitcointalk.org/index.php?topic=315263

Metadice (http://metadice.com) is a Litecoin dice game that has been running successfully for six months now, and it's attracted a fair amount of interest from very little advertising (mostly through Bitvisitor and also listed on Bitcointalk).

• 3,500 unique visitors (according to Google Analytics)
• 2:46 average stay
• 2,704 bets totalling 7565 LTC
• 492k transaction processing batches, 219k payment batches
• Provably fair betting algorithm, no need to sign up
• Support for blacklisting addresses to combat problem gambling
• Since it always provides a tx fee, blockchain bloat isn't a problem - 93.35 LTC has been paid to miners

From an initial investment of 60 LTC, the site balance has at times been as high as 262 BTC and has been enough to cover hosting costs, development costs etc. However the site's run out of LTC to bankroll, and we're not interested in continuing the site, so we're looking at selling it. We've already implemented all of the hard work with dealing with multi-bet transactions, unusual senders, invalid bets, too low/too high etc.

Technical features:

• Implemented using PHP/MySQL and served over Apache
• Fully automated and configurable, e.g. min_confirmations, min_balance, max_payment, min_bet, max_bet, house_edge, transaction_fee, loss_payment...
• Uses OpenID for administrator authentication
• Bet transactions occur independently from the website, and can run on separate servers - if the site is DDOSed, transactions will continue to process
• Designed to work with ANY BTC-based cryptocurrency: expansion plans included supporting betting in BTC, LTC, NMC, FTC
• Currently running on a 1GB VPS in Amsterdam (expires in 3 days)
• Various anti-spam and anti-DDOS protections in place
• Automated database backups

Any serious offers considered. We can also help with hosting, management, configuration and development of the site if necessary if you just want to provide a bankroll, or you can purchase the source code with a limited amount of deployment support, or anything inbetween. You will however have to deal with any legal/regulatory issues in your country of residence/operation if applicable. Send us a PM.

Today we updated the Litecoin daemon to 0.8.3.x, and everything seems to be working perfectly. Since we're now on 0.8.x, we can reduce the transaction fees for winnings and confirming losses to 0.02 LTC (from 0.1 LTC) - so your winnings will be higher!

Enjoy.

A confirming address is one that, if you lose on a 1 LTC bet, you will get 0.001 LTC back.

A non-confirming address is one that, if you lose on a 1 LTC bet, you won't get anything back. Instead you can check your bet status on the website.

Because LTC network fees are currently so high, it doesn't really make sense to send 0.001 LTC back with a 0.1 LTC fee (for example), so non-confirming addresses work really well.

Better to inform users of a site migration than wonder why everything's broken!

The server move has been a fantastic success, we're now being served from the Netherlands. Until the DNS has propogated you should be silently redirected to http://new.metadice.com.

We've also given the site a modern refresh with icons (from the Nuvola set), doubled the frequency of bet checks and payouts, and add tons of little details to improve your site experience. If there's any problems please send us an e-mail or a tweet.

The site's been so popular we're going to move to dedicated servers! We'll be migrating this weekend, which will let us enable much faster transactions, and to push out some minor interface updates. Downtime will hopefully be minimal. Bets will continue to be processed and paid out as usual.

The server switch will occur Sat 18 May between 5am-10am GMT / 10pm-3am PDT. It should be finished much earlier than that. Updates will be posted to @metadice on Twitter and to http://metadice.com.

Someone made a 1 LTC bet on an address with a 16.9 LTC minimum. It didn't make much sense to consider this a donation, so now if you make a bet that is lower than the minimum bet yet higher than the transaction fee (0.1 LTC), it will also be returned back.

We've had to increase the standard transaction fee to 0.1 LTC, which has also meant that the minimum bets for some addresses have had to increase as well (so that you would actually win something after fees!). When the upcoming Litecoin client based on 0.8.1 is released - which hopefully will have lower default transaction fees - we'll be able to reduce the necessary transaction fees as well.

So far we've had 225 bets win a total of 178.7 LTC.

I would really love to see Namecoin merged mining come back soon on stratum interface. FWIW I use Namecoins to register .bit domains and there is a lot of attention and activity in the Namecoin space recently... I might have to switch to another pool.

The Litecoin devs are apparently working on updating the client to 0.8, and they'll reduce the default transaction fee as part of the release. So one option is to recompile the client yourself (this is what I'm planning to do soon), or you can use the Android client which uses 0.0005 LTC AFAIK, otherwise you can probably just wait for the upcoming 0.8 QT client.

Definitely a market, however I still can't use remote backups because they're too expensive.

My backup repository (I use SVN) is 100gb, mostly from photos. At current market rates that's something like $30/month+ AFAIK, so instead I just make hardcopy backups and store them offsite. If I could get 200gb for $10/month I'd sign up, that's still a few years away though.

And erm, I don't think you can "one way encrypt" something for a backup service, you need to be able to decrypt it (thus making it non-one way).

You'll need to promote why your service is better than say Google Drive or Dropbox.

Still waiting to get a response back from my bid, or to get a new list of requirements so that I can update it.

FWIW I submitted a bid that involved monthly payments and regular feedback, you shouldn't be making a single large BTC transfer.

LTC transaction fees really are too high right now, the client assumes everyone's got 10,000 LTC+. I think they should be reduced from 0.1 LTC default to 0.01 LTC (or lower). Most clients actually ignore transactions < 0.0001 LTC (see mininput parameter).

Awesome. PM sent.

I've sent you a PM

I'm shocked this thread is still open... are you still accepting bids? I'm a very experienced web developer (13+ years) particularly in creating online communities/blogs/forums. Do you want openly posted bids or would you prefer PMs?

When I was first starting out with BTC I found Bitvisitor was a good way to slowly accumulate BTC (not to mention spam my wallet with transactions that were barely enough to cover tx fees ) so, with my new site Metadice (http://metadice.com), I was wondering how effective it would be as a marketing tool... I thought I'd share the results of my experiment.

Firstly the processing step was pretty quick. It seemed to rely on zero-confirmations, and cost me 0.031 BTC for 1000 visitors (I spent 0.062 BTC for 2000 visitors).

Secondly, I found out the hard way that my site was not yet optimised enough for that many visitors some quick terrifying Google and IRC searching later, I had tweaked Apache2's settings correctly, and put learning Nginx on my todo list.

These are the results from Google Analytics:

• Visits: 637; 564 unique (less than the 2000 expected)
• Page views: 1,176
• Average visit duration: 1:50 (Bitvisitor requires you to stay on the page for 60 seconds)
• Pages per visit: 1.85 (not many visitors click past the first page)
• Returning visitors: 11.3%
• Countries: US 23.8%, Spain 9.4%, Germany 8.8%, UK 5.8%, Italy 4.6%, Netherlands 3.6%, Canada 3%, New Zealand 3%, Russia 2.7%. I'm sure this is also dependent on the time that I requested the advertising, it was EU daytime.
• Browser: Chrome 50%, Firefox 40%, Opera 4% (IE 1.4% thank goodness)
• Mobile browser: Android 72.4%, iOS 27.6%
• Bets placed: ~5

So I think Bitvisitor is a good way to get a bunch of traffic, although it probably matches BTC demographics closely, most users will just ignore the page content, and very few will actually interact.

Yup here is another LTC dice site that I've just released

http://metadice.com

https://bitcointalk.org/index.php?topic=168211.0

I noticed that there seemed to be a lack of Litecoin dice sites, http://ltcdice.net/ seems to have disappeared and many of the others look boring, so over the last two days I've put together a dice site that tries to be a little bit smarter in the way it operates.

http://metadice.com

Features:

•     Fully automated betting with 98%+ break-even odds.
•     Faster to verify than BTC betting since LTC transactions are naturally processed faster!
•     Provably fair betting algorithm (of course), no need to sign up - but you must send LTC from a wallet that lets you receive coins on the same address (default client works great).
•     Improve your winnings and reduce blockchain spam by using non-confirming addresses - instead of receiving 0.001 LTC on a loss, non-confirmation improves your winnings by 0.2%.
•     Accessible over Namecoin DNS, http://metadice.bit - e.g. through dot-bit.
•     Combat problem gambling by blacklisting addresses - I was inspired by patrikr's comment on Reddit, if you find you have a problem you can force the system to ignore your bets.

The most interesting learning experience has been just how much the default Litecoin client tries to avoid blockchain spam. Any payment smaller than 0.0001 LTC is ignored by the client, and for anything but large transactions the client requests a 0.02 LTC transaction fee. Therefore you'll probably have most luck with bets above 0.02 LTC.

The site is kinda still in beta but if you have any feedback or ideas I'd love to improve the game. The site only has a limited wallet so maximum bets are low for a while. Feel free to PM me! I have a lot of other ideas that I'd like to implement e.g. accessible over Tor?
