rollinCoin.com caught changing provably fair hashes after betting

[rambeazle]

Using an incredible 10% house edge, and still it's not enough?

sir, i'm not scam and cheat.
is bad situation for me..
really fake.

Please explain how I could have possibly faked it. I would really love to hear your theory. How did the different hash get on archive.org?

I can think of a few

You work at archive.org and decided this is a good way to test your Admin powers?
You've hacked archive.org and edited their archive?
You've changed rollincoin's DNS-settings to a site controlled by you, posted the edited hashes, archived that site, and changed the DNS-settings back to the original?

There! Three very possible but highly unlikely explanations. Let's see which one rollinCoin chooses
[/sarcasm]

Rofl, I like the third one the most, I hope he goes with that one

1. There is a proof that CAN NOT BE FAKED that you have scammed him. Still you choose to call it fake.
2. You are calling him a cheater and scammer (as you are doing with me as well) only because he provided proof that you have cheated/scammed.
3. The more you lie the more stupid you look.

[MRKLYE]

Nice. I knew the site was bad news bears...

I removed my positive trust for him. The "I'm to stupid to understand how to scam" trick ain't flyiing here.

[RollinCoin.com]

is not proof!
he is scammer, cheater and hacker.
he want cheat game!
but can't make it.
he looser.

[DarkStar_]

who don't remove your post about scam, God will punish you! because we no scam and not cheat! Think about it!

The more you think about it, the more obvious it becomes. Would this be a bad time to mention your shady behavior as well from the past weeks? I was planning on making a scam accusation on you, but I was waiting for OP to get paid just in case you run. Looks like there isn't a need anymore.

[stingleword]

Second hash change. Watched it happen! Search the May 11 archive for the string 2ffc - this hash didn't change but the one immediately after it did. Compare to the current list - hash begins with 507b but the history archive shows a 2c30 hash in its place.

Note that this bet was the only one in recent history of that magnitude (0.05BTC). Larger bet == changed hash.

Cheating confirmed!

Edit

Just witnessed a third hash change. The original hash was 7caf30d6efa9fb33b44db579ffcd4d52 - a player bet 0.02BTC on it, and it changed to fc212fe6a78fdddac8d96d4995ad5682 on the list. Naturally, the wager was a loss.

Edit 2

.. And a fourth, almost immediately! 0.005BTC wager, original hash 2d12c1bde0305d035336ce144f29be13 displayed hash 3d18b097f856580e2f764d91a9efe374

The results of the bets are not generated in a manner that provides proof to the house edge. The results are arbitrary and the hashes show the results of the precalculated result. However the site is seen to be modifying multiple winning bets of larger sizes to become losers. For example, several seen cases are shown below.

The "provably fair" system in place is also weak and easily cracked allowing precalculation of results.

Here is the additional proof that bets are being modified to become losers:

tldr: I checked the provably fair hash before I bet, it was fe3b7dee0cf7cb7ea552995675306786. After I bet and LOST, the hash was 3509c457c164d3a813c833cb9f62a990. I have independent and irrefutable proof below.

Proof that the OP's previously identified hash was indeed a winning hash:

Code:

fe3b7dee0cf7cb7ea552995675306786:win:SecretKey=1205110482

$ echo -n "win:SecretKey=1205110482" | md5sum

That's it?
You can even brute-force this No wonder it has to be changed afterwards
