I have some problem verifying my bet, and I would like to know if I did something wrong in the process.

Hash: FA0CDD2ADE57124373BF56A3F13F60E1DB2201FDAA2FA0A4C3567583F3095AC1
Number: AA67C03CC2B48EC04C2C61D30068A46DC449D808D14736DAFC680A6C76492F20
Server Seed: 0111001111

The "Hash" is supposed to be calculated as SHA256(SHA256(Ticket Number + '-' + Server Seed)), but SHA256(AA67C03CC2B48EC04C2C61D30068A46DC449D808D14736DAFC680A6C76492F20-0111001111) is b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d and
SHA256(b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d) is 6ee32217ef397baeacc6f04a3024f4b06bac56777bf56bf93a5bc1c25c078fee



Sorry I was busy last week and did not have the time to make an update on this. In fact, I received a PM from OP a week ago (just shortly after I raised the question).

Hey, thanks for verifying bets!

After first SHA256 everything is right as you use UTF8 and result is b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d, but for second SHA256 no need to use UTF8 as there is no string separator, so input of second SHA256 will be just binary representation first hash.

You can try it in Bitcore playground http://bitcore.io/playground/#/units bitcore.crypto.Hash.sha256(bitcore.util.buffer.hexToBuffer('b765049511c7ee93d6ae9dcc9bd9125504cd90925f4ea04cff74b7767f1af76d'))

And that gives me the exact same hash I received before playing the game. Another way to do that is to use http://www.fileformat.info/tool/hash.htm to do the first hash as string and do the second hash as binary data.


TL;DR: The site is provably fair. The bet verification can be done easily. The OP is helpful and answers my question promptly.

Thanks for the update! So it looks like the site is worth trying.

As far as I understand the site works with Testnet Bitcoins which you can get free and with real bitcoins which you can deposit there right? So, no faucet with real bitcoins?

Website now works with real bitcoins, we updated it Yesterday, and preparing it for the final bug fixing and launch later this week. We will have "Demo Ticket" to try it for free.

Is beta testing over or you still need people to test the site ? I see there some updates were announced today but still it is in beta version and many things to be done like UI issues for mobile users.Is there any reward for beta testers or it is voluntarily ?

We are ready to pay a bounty (0.1 - 0.4 BTC) for any security bug you found.

We need some btc to start trying on this loteries site?? Or just visit the site and then give some review here??

BitKong is using Testnet Bitcoins (they have no value) which you can obtain here http://tpfaucet.appspot.com/ or https://testnet.coinfaucet.eu/en/ to start playing (you just need to copy your deposit address and paste it in faucet website), and yes, we are looking for reviews and feedback, thank you so much!

Maybe make it mobile friendly is good idea.

Website fully responsive and mobile/tablet friendly, we just need to reduce first loading size little bit!

Sadly would like to have seen your site but waiting for 4 minutes for your site to download on my phone is not acceptable in my case.

Sorry to hear that Sad

Site is not small (~3MB) but usually loading only few seconds even on phones with 3G.
Can you please let me know model of your phone and connection speed you have used? We will try reproduce and fix issue.

Actually the size of BitKong.me is 4.3mB and loading time using broadband connection is 10+ seconds.
You should optimize it.

Yes, we have background sound which is 2mb, which is gradually loading in time of gameplay, and other 800kb image, which we think to change to SVG.

We use best practices in browser caching and also we use CDN for all assets of the website, second load of the website should be around 30-40kb.
