We had to wait till block #389006 (always 6th block after draw finished.) The hash of that block is used in the calculation: https://www.blocktrail.com/BTC/block/0000000000000000006d52ca33c82ed5320d21be7d8237020fcd037235403cd2

I am personally calculating the results myself and obviously Ryan will also calculate it to determine the winner. This calculation can take a few hours. So after a few hours we will have the result Smiley If you want to verify the result, you can also run the calculation yourself (but takes time and you should have some technical knowledge.)

Unofficial result for #6: 25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc



edit: mm so the "Verify" script says 1,553,035,541 tickets, but the Draw page says 1,553,025,541. This gives 2 different winners (by verify script 5 BTC bettor, by draw page 10 BTC bettor):

>>> print 0x25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc % 1553035541
1100532042

>>> print 0x25238990480fd040ff51f793de5f998d4c3e062f09feaa0f6cf6bab34e44edfc % 1553025541
260547462

Which one is correct?




edit: previous draws also seem to add 10k tickets at verify script? So I am guessing the draw page is correct.

Thanks for this, the verify script was showing unconfirmed transactions as part of the draw. I forgot to filter them out.

The fix is:

Code:
--- verify.js
+++ verify.js
@@ -123,7 +123,7 @@
         data.txs.forEach(function(transaction) {
          
           var height = transaction.block_height;
-          if (height > from) return;
+          if (!height || height > from) return;
           if (height < to) {
             done = true;
             return;


and the winner is announced:  https://www.pevpot.com/draws/6 !

I wrote a script to verify the first draw. Here's what it says for this most recent draw:

modulo 1553025541

Edit: I just noticed that https://www.pevpot.com/draws/6 has off-by-one errors.

The first tx bought 230,000 tickets, 0 through 229,999 - but the linked page says 0 through 230,000 (which is 230,001 tickets). Taking 1 from each number in the 'to' column would fix this.

Just an old habbit of mine to express ranges as  [inclusive, exclusive), but it's a bit confusing so i'll change it to  [inclusive, inclusive] now


Edit: fixed

Hi,
I am very fan of Ryan and Pevpot. Thanks for this honest, fair website.
Just a remark... for beginners like me, it is IMPOSSIBLE to know if I won, or not.
The only way I know is checking here when you say "the whale won", then I know I did not win.
So, for the last draw, the winner betted 5-10 btc right, then it's not me?

Hope for the next draw you can say how much was betted, then I have a first idea if it's me, or not... Smiley - also this way we'll have the risk-reward ratio Smiley

Thanks again, astonished there is not much more players.... no problem then I have more odds to win... less... Smiley

Well on https://www.pevpot.com you can scroll to "past draws" and click on latest: https://www.pevpot.com/draws/6 it's pretty clear who won on that page?

But I agree it should be a bit more highlighted on homepage. Maybe a block under current draw on homepage with "Last draw #6, Prize: 15.66BTC, Winner: 61edb7.. of 10.1009722 BTC, Details". If the draw just ended it should say something like "We are calculating the result, this takes a few hours.. come back later to see if you won!".

Nice and innovative lottery project. Congratulations!

It loosely reminds me of a crazy idea (not so +EV) I had long ago:

https://bitcointalk.org/index.php?topic=409660.0

If marketing is well done, your project may become the Google of lotteries!  Grin

BTW (talking about Google) why not displaying AdWords like style of ads from sponsors alongside with their banners/images?

Pot decreased considerably...

Tip: raise min ticket purchase to .001 BTC so things get more interesting once more... Wink

Seems like the site owner can just deposit 10 BTC and have a huge chance of winning.

I looked at the site and red flags pop up saying thats what is happening.

If you look only 1 person buys a ton of tickets and wins every time.

But that doesn't mean the site owner is cheating (because the game is provably fair).

p.s. but it might mean that there is a considerable conflict of interest happening every round...
