Hello, i'd like to try out your site. My username is Mooshire.

Regarding Provable Fairness:

How is this actually provably fair? We take the roll, the client seed and the server seed and hash them together to get the server hash? This means that you can make the roll whatever you want? Please clarify how the rolls are actually calculated. I will add a roll verifier for your site to http://bitcoinmaniac.com/verify if you can tell me how this is actually provably fair.

We provide a hash of the roll, user decided client seed and we add a secret to prevent the results from being derived from the hash provided. There is a SHA 512 form embedded in our site which allows you to verify the results after the secret has been released. To verify your rolls please visit our verification page (http://gigadice.com/verification.php).



I have accredited every account I have missed thus far.

But this isn't provably fair, this is just provable results. You can change the roll to whatever you want, the client seed has nothing to do with the roll. This is deceptive and not actually provably fair.

Could you expand on this and maybe suggest what changes or additional information would be needed to show that the game is 100% provably fair?

I think my response may have been unclear. There is a server seed and client seed (user can change) provided before the roll and a daily secret. Results can be proven once the secret is released. In order to verify that the bets were provably fair you take the roll+clientseed+secret and if it equals the server seed provided before the roll it is fair. This is the same system used by many dice sites, I'm open to suggestions and appreciate any feedback.

If what you're getting at is that he can make a fake account and win lots because he know the secret(s), any site can do that - so don't bother bashing him...

This is not the same system used by many dice sites. You take the roll, which you can make whatever you want, and then hash it with the client seed to provide what is called "Provable results". This is not provably fair. This shows that the roll did not change after you bet. You could still be setting the rolls low and making people lose. It would still "verify" but would not be actually provably fair. If you want to make something provably fair, there is a good way to do it.

Take the SHA512 hash of the client seed + server seed. (Provide the hash of the server seed beforehand)
Take the first 8 characters of the hash, and convert them to decimal form. Then divide by 42949672.95, which will give you a numeric value between 0 and 100. Round this value to the nearest hundredths place.
This is your roll. Now, we know that you did not predetermine the roll beforehand, and we can check that this roll was made with our own client seed, and is fair.

To simple-dice: This is not at all what I am talking about, don't post before you know what the conversation is.

In the 2nd par. you said "server seed."  What do you think a server-seed is?

And the first 8 characters of WHICH hash?  You said hash two things - I don't think you really understand what provably fair is nor did you explain it properly.

What you're suggesting is another way to come to the same conclusion both are "provably fair". Here is an excerpt from Mem reinforcing that this is actually "provably fair".

Ok then tell me, how can I verify that you do not just choose the rolls and that they are influenced by my client seed in a hash? Maybe i'm just not understanding you.

I was describing a system for creating provable fairness. You are talking about the owner betting on his own site.

Rolls are verifiable once the secret is released. Once the secret is made public you can go here (http://gigadice.com/verification.php) and take the roll+client seed+secret and hash them together, if it equals the server seed provided before the roll it is fair. Since the client seed is editable there is no way we can manipulate the results. Thank you for your comments and feedback, I have accredited your account with some balance. We're always looking to improve ourselves wherever possible.

No - reread the post...  My first post was, not my second.

GigaDice, you have not answered my question. How does my client seed influence the roll if it's only purpose is to be hashed with the roll? How does my client seed influence the roll? You are avoiding this question.

You avoided my questions...  I'd like a response too.

What exactly is your question? Please post it again.

It isn't necessary to have the client seed influence the roll as the client seed's purpose is to verify that the bet was provably fair which it accomplishes. Each site has different methods of "provably fair" and they all solve the same problem. Please refer to this wonderful topic mem made which should shed some light on the intricacies of provably fair and provable results.

Thanks!  :)

Then how can I tell that you don't just create a bunch of low rolls and hash them with my client seed? What does the server seed ultimately accomplish? How do I know that you don't just make a bunch of losing rolls?

admin is ignoring my concerns about provably fair and is stealing site design from Stunna. Not provably fair and stealing another site's design? No thanks.

In the 2nd par. you said "server seed."  What do you think a server-seed is?

And the first 8 characters of WHICH hash?  You said hash two things - I don't think you really understand what provably fair is nor did you explain it properly.

I was gone for maybe a few minutes grabbing some dinner. I will address your concerns about provably fair as you seem accustomed to Primedice's method which is perfectly fine. In regards to your previous post, it would not work as the server seed is provided before hand and the client seed is provided by the user which makes what you suggest impossible. The purpose of a server seed is to prove that the bets aren't manipulated as it's provided before the bet and since the client seed is user submitted it does so in a "provably fair" manner. In regards to stealing another site's design, we used a modified bootstrap for the back end and approached a web designer for the front end development and since most site's use bootstrap (letsdice) they tend to look similar. Some concepts were taken from Primedice as we wish to provide the best possible product for our users.

The way most sites do provably fair:

Client seed: Provided by the user, used to make sure site is not cheating
Server seed (or secret): Used by the server, not provided until after the bet.
The server seed is then usually hashed and then presented to the user before the roll is made.
The outcome of the bet, usually a base 10 number between 1 and 100 is derived from the hash of the server secret and the client seed together.

Yes, I understand but our site remains "provably fair", I think you're confusing provably fair and provable results. If we didn't allow for users to edit the client seed before the roll than we would be not be provably fair but since users directly influence the hash which will verify if the bet is provably fair we accomplish the same thing. There is many ways to be provably fair, whether it be the primedice method you're accustomed to or through blockchain they accomplish the same thing.

What I don't understand is this: How do I know you don't just pick low rolls ahead of time? Sure, they wouldn't change between when I see the server seed and after I bet, but they're still low rolls. I'm sorry if i'm bashing on your site because i don't understand something, but how do I know the site doesn't generate low rolls?

The table and few things in the header look similar, but the actual betting platform looks very different.

Failing to see why a similar table and header matters especially considering the sites are similar as is...  He didn't ignore your concerns - he just uses provably fair in a different way.

You need to get the stick out of your ass and the sand out of your vagina, IMO.

Tired of dumb jr. members. Ignored.
EDIT: Especially sock puppets of scammers that try to make scam dice sites that get shut down.

This is completely understandable and I will try my best to explain this concept. I think the problem you're having is "selective hashing" which in theory any site can utilize, even when using the aforementioned provably fair method. Our method of provably fair once verified will show that bets aren't tampered with, although this requires waiting on the daily secret. Since the user can change the client seed which ultimately influences the hash which HAS to match the server seed also provided before the roll.

Is simple-dice working for gigadice ? Well, anyway, consider the following text taken as is from the site in question:

"""
Prior to betting, you receive a "Server Seed" and a "Client Seed." The Server Seed is a combination of your roll, your client seed, and our secret - hashed.
"""

So this is obviously wrong. How can the server seed (please read exactly as it is written above, because those are the current words used in the site) include the roll (which doesn't exist yet) prior to placing a bet ?

The best way to solve all this: give the code used for checking the rolls.

But even then we don't know if it's the actual code. You keep trying to tell me that it's provably fair, but it 's not. The roll can be whatever you want it to be before it is hashed, and this is not provably fair.

Yes, once the secret is released at the end of day you will already have the roll, client and server seed. It would be impossible to verify a bet before it even happened which is what I think you're claiming. I will look to correct any grammar mistakes on the site which may confuse users, thank you.

No it cannot since the client seed is editable and shown before the roll, I'm not sure if you have read this (https://bitcointalk.org/index.php?topic=266791.0) topic but it explains in detail what is and what isn't provably fair. Thank you for your concern we will look into adding the provably fair you stated in version two of our site as it seems to be more popular.

There was an error with your log-in.

Please add SSL too.

TF, is this actually provably fair?

SSL will be added once the site is incorporated. What was the specific error so I can try my best to diagnose it.

There was an error with your log-in. was the specific error.

I would also update Apache if I were you. http://www.cvedetails.com/vulnerability-list/vendor_id-45/product_id-66/version_id-93077/Apache-Http-Server-2.2.15.html

What is your max bet? You should add this information to the site!

Also, support Inputs :)

As usual I agree with Tradefortress :)

Max bets will be displayed on the betting page, I will look into adding this information. Inputs withdrawals are currently supported and will support deposits in Gigadice 2.0

Thanks for the satoshis. My suggestions:

1) Considering it is possible to bet small amounts i think it would be important to show more digits on the balance.
2) There should be a confirmation to cashout. I clicked on the button and now the cost to send the satoshis back to the site is bigger than the satoshis I cashed out.

Thank you for the feedback, I will look to implement those changes. I have accredited your account with some balance.

Thought I'd add a few more pictures of Gigadice 2.0 as I've gotten a few PM's regarding it.

https://i.imgur.com/urlzbHi.png

Are you going to consider adding inputs.io?

but inputs.io have many troubles around there most of time

It's only having trouble right now, normally it works great.

For what's worth, so far you have entirely sidestepped the discussion regarding the provably fair method used at gigadice. Can't you clearly explain it ?

Anyway, here is how I understood the process. For this example I took the bets 1 and 8 at http://gigadice.com/verification.php?betid=1 and http://gigadice.com/verification.php?betid=8. Bet 1 rolled 18.71 with user seed 208606, Bet 8 rolled 56.03 with user seed 597414. To check the outcome is the expected one, concatenate the rolled number, the user seed, and the daily secret of 61f476d793488e3d47fd348011c203084c60be24 for these rolls. Apply SHA 512 on the concatenated message and take the hex digest, if they match the one published at "Server Seed (Hash) for that Roll" for that bet, then the result is the expected one. For these rolls, the hashes match -- EXCEPT it is missing the most important step: WHAT did it do to roll 18.71 and 56.03 there ?

There are yet two other issues about how you're handling this (beyond not properly answering it earlier). First issue: the hash of the daily secret 61f476d793488e3d47fd348011c203084c60be24 is not shown anywhere, if it is I can't find it. Second issue regards the way you describe your method, if it is done exactly as specified there, then it is not provably fair again.

Here is the part that is wrong in every instance: """Prior to betting, you receive a "Server Seed" and a "Client Seed." The Server Seed is a combination of your roll, your client seed, and our secret - hashed""". This is telling me I get a user seed before the bet is placed, it doesn't clearly say that the player sends its own seed. /If/ it is not the player who specifies his seed, then it is not provably fair and it should be obvious why that is the case. The description regarding "Server seed" is also confusing, but I mentioned this in an earlier post.

Since this is relatively long, let me resume: 1) you are not describing how the rolled number is picked; 2) the way you describe "user seed" makes it not provably fair; 3) "server seed" is confusing as it is not a seed of anything.

What you're suggesting is implementing a system where the site would be not only be provably fair but have provable results as the user seed would directly influence the outcome of the roll. I see you have managed to test our current system and have done so correctly. In regards to your question about the "client seed" and not having it directly influence the roll it is not necessary to be labled provably fair albeit it would improve our transparency. Which is why we have already discussed implementation of the aforementioned provably fair system. The daily secrets can be found here (http://gigadice.com/secrets.php). It would be impossible or very illogical to force the user into submitting a client seed every bet, we do however allow users if they feel the need to change it if they feel the need to. If you're wondering how the rolls are determined it is through a simple php rand function.

Wow, take some time and think about what you just wrote there. How can the user possibly know that the roll was done in a provably fair manner considering what you just wrote ? Here is the result of "a simple php rand function": 32, who can you know I did it in a fair manner ? You (the player actually) have no way to check that with this current method.

Pay attention to this: neither the user seed nor the daily secret have any effect in the rolled number. If you know of any site that do this, you picked the wrong example to follow.

I can't log in to my account anymore, is it because all accoutns were deleted?

I have answered this multiple time at the moment the client seed doesn't affect affect the roll but we're looking to implement it in the future. I'm looking to ways to increase our provability and transparency and very much appreciate your feedback.


@Monbux, we wiped the database when we launched officially meaning all accounts in the BETA were deleted. Please re register and I will accredit you with some balance for participating in our BETA.

Do you understand that gigadice is not provably fair ?

Please refer to this (https://bitcointalk.org/index.php?topic=266791.0) topic as our system may not be the what you're used to seeing but it is provably fair.

Can you give a proper answer on where am I wrong ? Can you show how your system is provably fair after all those points above ?

According to the very own topic you mentioned, you managed to: a) make an unprovable fair system; with b) unprovable results. What am I supposed to take from that thread ?

This is what I've been trying to get him to understand. He doesn't seem to get the difference between provably fair and provable results.

Provably Fair: The house picks a number in such a way that the user can verify that the house did not have any control over the outcome of the roll

Provable Results: The house supplies a way to show that the outcome did not change from when the hash/seed was provided and after the roll. There is no way to verify the house is not controlling the outcome of the roll.

GigaDice has provable results.


(He also doesn't know the difference between credited and accredited)

Thank you for your feedback and suggestions thus far, we will definitely be adding a different method of provably fair in Gigadice 2.0. I have added some balance to your account for helping us improve our site. If you have any more suggestions or questions feel free to message me or contact me through email at admin@gigadice.com

Is gigagold essentially money? US laws making it illegal to bet with anything besides BTC.

US laws don't apply as we have prohibited US users from accessing Gigagold.

There seems to be a problem showing the balance, recent bets, and stats when viewing with Chrome, but seems okay with IE. Or is this just me?  ???

This seems to happen sporadically to a small portion of our users. I've found that closing the browser and re visiting the site solves the problem. Nonetheless we're looking to find a permanent solution to this and pinpoint what exactly is causing this. I have added some balance to your account for your troubles.

Looking at your verification page I was under the assumption that the client seed DOES affect the rolled number.

Is the result generated in advance of when I click on bet?

It is, that's what we've been saying.

Bribing me isn't going to keep me quiet.

Signed up with username: kklljsw

Thank you

The seeds /do not affect/ the rolled number, not even the daily secret affects it. The user seed and daily secret are only used to show that sha2_512("whatever roll it decided to output" + "user seed" + "daily secret") == hash shown before the roll. The user seed is completely irrelevant.

The operator also cannot properly explain the process of producing a roll. It was mentioned that the rand function from php is used. If that is all there is to it, you are using a method known to be breakable and then an attacker will guess the next outcomes and will bankrupt the site.

I have brought up the changes to provably fair to my developer and they will be implemented within a day or two.

who coined this term : "PROVABLY FAIR" does anyone know? ::) tia!

Thank you for deciding to change your "provably fair" system to an actually provably fair one. What hash algo will you be using? I suggest SHA512. Once you decide, tell me and I can add you to http://bitcoinmaniac.com/verify

We're using SHA 512, I have yet to change the description on the verification page which will explain the new method in more detail.



I have added balance to any of the users I have missed.

You don't accept US players? Good lord. Not again with that shit.

*cough vpn cough*

US players are welcome to bet BTC -> BTC. The only restriction placed on US users is that they cannot utilize fiat gambling and withdrawals and therefore are blocked from our Gigagold betting page. Since I've gotten a few emails asking if we will integrate on chain gambling on Gigadice 2.0, I thought I'd make it clear we plan on doing so.There are tons of new ideas such as SMS gambling being tested at the moment and can possibly make an appearance on official launch.


Here is small sneak peak of On chain gambling.

Kudos to GigaDice for changing his method of provability so fast.

Can't wait to test it tomorrow when the secret is released - can't really tell the difference so far.

I love the site though!

Automated betting has been implemented on Gigadice 2.0 which is set to launch within the month.

I have added balance to your account. In regards to provably fair, we implemented a new method which is explained in detail here (http://www.gigadice.com/verification.php). A new design has already been made and will be released soon.

Here is what the design will look like.

A couple errors on the page:
"and then convert the hash to hexadecimal"
The hash is hexadecimal. You're converting it to base-10 or decimal.
"you're changing the result, or winning or losing number."
Just doesn't make sense

How does it not make sense?  If your change your client-seed you are changing the result which is also the winning or losing number.  Was there something I missed?
