There is no Game Verification Script on github.com. There is no trust to it. Service offline for honesty check is necessary.With a chain everything is all right and with result, I am not sure.
I am not a programmer. In (Node.js) I don't understand.

You can find an open source script to verify rolls at https://jsfiddle.net/Dexon95/2fmuxLza/embedded/result/. To see the source code just click on "Edit in JSFiddle" at the top right.

All the guys. I am convinced that everything is honest. I delete my negative comments.

Few in bitcoinland will admit they are wrong even when faced with evidence. You have my respect.

Thanks! I have checked a chain more than 100K of games. Intervention wasn't!
Justice is proved.

Some clarification of my previous post: The function parameter "seed" is the game's hash in binary form and "salt" is the salt that was chosen during the seeding event in textual form (0000000000000000004d6ec16dafe9d8370958664c1dc422f452892264c59526).

To calculate the multiplier from the hash of game #1 for example:

Code:

const salt = '0000000000000000004d6ec16dafe9d8370958664c1dc422f452892264c59526';
const hash = Buffer.from('9f57575fd54cd441e962448537e155ace9555df10cd27fa817bbcaf48a59ebcf', 'hex');
console.log(gameResult(hash, salt)); // outputs 15.49

Devans is still a question. How to convert HASH to Busted?I did not find this information.

The reference function (Node.js) that calculates the multiplier from a game's hash is published in our seeding event thread:

Code:

const crypto = require("crypto")

function gameResult(seed, salt) {
  const nBits = 52 // number of most significant bits to use

  // 1. HMAC_SHA256(key=salt, message=seed)
  const hmac = crypto.createHmac("sha256", salt)
  hmac.update(seed)
  seed = hmac.digest("hex")

  // 2. r = 52 most significant bits
  seed = seed.slice(0, nBits/4)
  const r = parseInt(seed, 16)

  // 3. X = r / 2^52
  let X = r / Math.pow(2, nBits) // uniformly distributed in [0; 1)

  // 4. X = 99 / (1-X)
  X = 99 / (1 - X)

  // 5. return max(trunc(X), 100)
  const result = Math.floor(X)
  return Math.max(1, result / 100)
}

I respect that a lot. It was good discussing the system in chat with you (assuming that was you).

Great, thanks a lot for the API documentation. I'm not sure, if userInfo.profit works well, but userInfo.balance, so e.g. something like this :

Code:

if (config.win.value === 'base') {
   currentBet = userInfo.balance - 33333;
} ...

..works like a charm. Thanks again!

Happy to help! Both fields should work as expected–even in simulation mode, where it will use your simulated balance and net profit.

And anyway, another question - is it possible, somewhere in the script, use some variables like NetProfit or "Current_Amount_on_My_Account" or something like this ? Let's say I'd like to bet (in case of win) 1/1000 of NetProfit (or CurrentAmount, doesn't matter), so my question is, if e.g. this part of code :

Code:

if (config.win.value === 'base') {
   currentBet = config.baseBet.value;
} ...

is possible to replace with something like this :

Code:

if (config.win.value === 'base') {
   currentBet = round(($NetProfit - 20000) / 1000);
} ...

Thanks again, devans, for all your help and communication!

Yes, scripts can access the current net profit at userInfo.profit. For more information on what else the userInfo store provides see its section in the API documentation.

I suggested a way to prove justice. That no one had any doubts about juggling hands.
There are seed. All the distributions are known for the front admin. So why not do this?

Example.

GAME #667480-GAME #667486

Your proposed system would allow you to batch verify that N games were predetermined. However it besides the usability problems (you need to collect the result hash, then collect all N games hashes before you can verify) it also suffers a critical flaw: it doesn't prove the hashes are drawn from a fair distribution. If your scheme was used, Daniel could just pick all bad hashes and then commit to them.

As scant says, the hash chain method is far more elegant and offers all the guarantees yours does, plus more.

Like Ryan explained, bustabit's provably fair scheme already provides the same guarantees your method would.

ATTENTION !!! Bustabit SCAM.Ne give your money.

I'll just copy & paste my response to the last time you made baseless accusations against bustabit:

Bustabit SCAM. Children do not come here. Here in plus only fake accounts. Danielle will select your money.
I am sure that Daniel pays here for the positive posts.

bustabit is provably fair. We prove that the odds are as advertised (1% house edge) and we prove that all game results are predetermined, regardless of how or when players bet.

If you are interested in the technical details, have a look at our seeding event for the technical details. If you just want to verify that the games you played were fair, you can use this open source tool that Dexon wrote.

If you think there's an issue with the provably fair scheme I am very happy to discuss it with you here. However, I'm sure everybody here would appreciate it if you could find some other way to vent.

The bustabit client hasn't been updated since July 20th and I haven't received reports of the problem from any other players, so its cause probably lies elsewhere.

For what it's worth I test bustabit with Chrome during development and haven't noticed any performance issues. You can improve performance a little bit by enabling CPU saver mode from the game settings. To get there click the gear button to the left of the chat box.

Ok, it will probably be related to my environment, so I'll try to do some tests (or migrate the browser with Bustabit elsewhere).

About "CPU saver mode"; great hint, thanks - I'm not exactly sure, if I had or hadn't enable this before (as the checkbox displaying of this function is weirdly under the frame - but again, it could be related to my OS / environment), but I'll definitively try to enable and I'll see, if this would helps or not.

Several days ago, my Firefox started to crashing (with running Bustabit session) everyday, around 3-4 a.m. (UTC); has anybody similar experience, or it is more probably related just to my OS and environment ?

And the second question - This Bustabit (v2) is running smoothly just under Firefox, I tried Chrome, Chromium, Midori and PaleMoon, but it doesn't run there. Has anybody the same experience ? Thanks.

So its literally the same li bustabit but just the dilution fee?

The dilution fee is just part of the new investment system. While the investment system is one of the most significant changes in v2 of bustabit, a lot more than that is new. See this thread's OP for a full list of changes
