What is the problem with the sentence? I was quoting myself to show you the problem AND ROFLMAO THE CLIENT SEED ISN'T BEING RANDOMIZED WITH CRYPTOGRAPHICALY SECURE ALGORITHMS CLIENT SIDE?!?!?!

Way to protect the noobs vets.

Yeah, it's fine. I was just confused who was saying what there.

As I understand it, the player is responsible for setting the client seed, but I'm not sure.

Did you think the client seed was being randomized client side? If so, how would your original criticism have been valid at all? From their verification page it sounds like the user gets to choose both client and server seeds, which is weird.

Here's my post about it, with their answer not far below:

I gave you a piece of psuedocode that breaks the current "Provable Fair" algorithm, if they are using it on the server side they have total control over the results but I think you got that by now already, simply don't have an answer.

I didn't read the pseudocode; I didn't get past you quoting yourself and apparently calling yourself a charlatan. But now I understand. You weren't replying to yourself, you were repeating something you posted in a different thread.

You seem to be saying that the site can keep trying random server hashes until they find one that makes the player lose, right?

The reason this doesn't work is that they publish the hash of their server secret before the game, and before the player picks the client seed. If they later change the server seed to make sure they win, its hash won't match the previously published hash.

The problem with the whole scheme is that they make it so hard for the player to change their client seed that the players probably never change it, and so the game is open to abuse. The server can assume the client seed will remain unchanged and find a server seed that lets them win, then publish its hash before each game.

This will be fixed once it's easy for the players to change their client seed which I think is something Stunna has already said is in the pipeline.

Is it just me (is the problem with me?) or are you (primedice) a charlatan?

Well I have read it about 10 times and I still do not understand, enlighten me.

Is it just me or are you a charlatan?

Are you calling yourself a scammer now too?

I guess you're about the only person left who you didn't accuse to wrongdoing so it had to happen eventually.

Or would you like to try formatting your post so it makes some kind of sense and asking a reasonable question if there's something you don't understand?

I do not follow how PrimeDice is provably fair if a random server hash is present in the sha512?

http://primedice.com/verification.php

Well I have read it about 10 times and I still do not understand, enlighten me.

The client seed is generated randomly client-side and the server seed is generated randomly server side, the secret is static, generated once per day.

So if I generate the client seed 9363438 and submit a bet while the secret is 396d4ba70ffc05b28f636438cd7f02479d6aca22 the server seed can provide a source of entropy thus rendering the whole process useless, e.g. I can:

Code:

do
{
$server=randomHash();
}
while(round(hexdec(substr(hash('sha512',$seed.$server.$client), 0, 8))/42949672.95,2)>$bet)

Is it just me or are you a charlatan?

Woah, congrats. How'd you win so much? o_O.

Also, really looking forward to the affiliate program Stunna!

Just played a mix between 50.5 and 20.8.

Basically went in expecting to lose, I think that's the trick Tongue

Very nice, bitcoinm won 200BTC like this too, expecting to lose lol. I'm not sure about 20.8, I always have a feeling you'll lose again before you have a profit of it.

I'd like to see it implemented though, you can already more or less do it, but it just costs more in TX fee's.

That's a good point, cashing out small amounts would just increase TX fee. One of the main benefits of PD is that you're able to do an entire session of bets with only one fee Cheesy

I was wondering, would it ever be possible to do partial payouts? Currently you cashout everything, but it'd be nice if I could say I wanted to cash out 0.1, instead of all, in example.

This is not needed and i think Primedice would go against itself. Thats the gamble man - if you don't want to lose much, don't bet much - it doesn't really matter how much you got on your account until you go into "gambler insanity" and bet more and more and lose it.

Hmm. I don't think this will change the risk much more Tongue

Maybe it could affect the houses reward though, since people will cash out more often, and I think that's bad haha.

Would be possible, not sure how we'd implement it though.

There are a lot of features we will hopefully be able to add in within the next 72 hours which we think you all will love, stay tuned.

I bought a $390 moneypak last night and never was able to get 3 bitcoins for it. Now with this dumb price rise I'll never get that. Congrats to the latest winner tho!

Btw @Zaih a truee gambling addict would've kept going until they at least got their investment back. If you are an addict its shocking you stocked after taking a loss of 50% haha.

I guess you could say I'm a controlled gambling addict Tongue

Still doesn't change the fact I always get urges to play on every single casino that pops up in this forum Tongue
