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.

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

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... - also this way we'll have the risk-reward ratio

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

[NLNico]

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!".

[Harpua]

Good luck to everyone by tomorrow   ... This will definitely make a nice Christmas gift to whoever wins.

[RHavar]

Just 3 blocks to go (~30 minutes!). I'll make sure the winner gets it in time for xmas!

Good luck to all!

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! 

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...

[btc-raffle.com]

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...

[syndria]

I think just a bit unfair like last draw where someone deposited 10Btc and won. Only those who can deposit higher amount has the high chances of winning and if you dont have you are just donating coz you have0 0% chances to take the current prize pot.

A maximum tickets per participants is necessary to be fair to those cant afford to buy high enough.

[Financisto]

^^ If max number of tickets per player is set, a whale only needs to buy several of them in order to divide his 10 BTC bet.

It works like real life: "Offline" lotteries work that way too...

If that whale bets 10 BTC and loses (and it's possible), that's gonna hurt...

The site is too new for someone to bet 10 BTC on a pot to win like 0.00001 profit.........

Think about it ryan the site owner who also owns bustabit would be the only person who would do that.

If  you can't see ryan the site owner is the person adding the 10 BTC bet you are blind.

I am blind lol

even Ryan if he would always  buy for 10 BTC tickets to win 0.2-05 BTC it is his risk and would be still a fair lottery but it would not make sense because if you lose once the 10 BTC it will be a long way to win it back and he can lose again on the way he wants to win all back. IMO he would be stupid to do so

Its not a risk seeing how he will have millions of entries giving him a 99.9% chance to win every time. 

Do you really believe someone is going to drop $4,000 on a pot worth $5?

You are blind lol

[dooglus]

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

So could anyone else. You also have a small chance of losing 10 BTC. If you want to take that risk, do so. It's +EV after all.

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

I don't see them when I visit. Scan for malware.

If you're saying you are seeing something that makes you think the site operator is cheating, please share it with us. The owner went to quite some lengths to set things up such that it is impossible for him to cheat. If you see a way he could be cheating I would love to hear about it.

I can't help but notice you have what looks like a URL for your account name. I wonder if perhaps you run a competing service. Could that maybe be colouring your vision?

I checked your so-called provably fair system and it's kind of laughable. You use the txid of the "last bitcoin transaction".

As you can see, the hash of bitcoin transaction is totally unpredictable

The problem is that the hash of a bitcoin transaction is entirely predictable. I can pre-generate thousands of them and have them ready for broadcasting. Then I pick a bunch that make my ticket win and broadcast them at just the right time. If I was you, I could then pick one of them and claim that it was "the last bitcoin transaction". In other words your system isn't provably fair at all. It's exploitable by players, and cheatable by yourself.

I think you should rethink the system you use before making such a half-assed complaint against a better thought out game.

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

Check the first draw. I bought a ton of tickets and lost. I haven't played since.
