Cheesy Nice win!

It's kind of cool that every ticket bought has a direct impact on the outcome by changing the modulus used. A difference of a single satoshi in either direction completely changes the result:

>>> print 0x6e466cdd13cc80b1137addf46362bbe3714fc9bf7faef9aba930554d3e080ba5 % 2370006598
1757345155 ... and the 5.92947120 bet wins

>>> print 0x6e466cdd13cc80b1137addf46362bbe3714fc9bf7faef9aba930554d3e080ba5 % 2370006600
886980269 ... and the 10.82969911 bet wins

I got the same as NLNico using a modified openssl version. I ran into the 32 bit integer limit too, so did this to bypass it - it saved me having to rebuild openssl - I just copied and modified the function with the 32 bit limit:

Thanks for doing that BTW, I created a mini repo for it: https://github.com/moneypot/pevpot-stretch

I'll try wrap it in a node module too later.


(But for now, I'm still running the verification in the native php and native js solution. Make sure they corroborate the same stretched hash. )


Update: The native PHP solution is matching  <modified openssl>, so I'm getting quite confident it's correct.
I'm still waiting for the native javascript one to terminate, before I'm sure though =)

I'm running a Python version too. It has been running for 12 hours so far:

Code:
>>> time.ctime(time.time()); pbkdf2.PBKDF2('000000000000000009b7fb236187f120a0c86eb8785f099a8d197dd34b9d2553', 'pevpot', 5000000000, hashlib.sha256, hmac).hexread(32); time.ctime(time.time())
'Tue Nov 17 01:50:44 2015'

I'm a little butthurt that my last minute snipe bets didn't pay off for me. The 10.8 BTC was my 10 BTC investment at moneypot plus profits over the last couple weeks, and the 5.x was as much as polo would let me withdraw in a single day. But I'm glad to see them go to a long-standing JD player. Smiley

I've updated the draw page:
https://www.pevpot.com/draws/1

And I will shortly make the payment of 23.87646599 BTC to cowbay after my last script for verification has finished running (or Dooglus' python one). If anyone wants to dispute the outcome, now is your chance or it will be considered valid and paid =)  


Once again, congratulations to cowbay. And thanks everyone for participating!

I think I will try it. By the way, why only one prize, and not multiple prizes?

I'm a bit of a sucker for simplicity, so I do like the idea of "winner takes all". Provably fair doesn't imply that you're probably going to win, it just means that you can verify it's fairness. =)

Look good. I am running a free lottery site and I am sure this is the best place I can advertise my site. Sponsored some Bitcoin into round #3. Look like I am the highest bidder so far. I know I will be knock down as soon as Just-dice operator is online. Let me screenshot it first ... LoL!

Lol, actually the 5th on current round paid BTC0.0111, so you should make top 5 with BTC0.017. But yeh, maybe not first hehe Tongue I recommend to check last moments too, it is a bit tricky/disappointing if you end up being 6th by a few bits.


In other news: prize already BTC5.77 - hope it will be a big one Smiley

......sorry for the late post, that was a long rage fapping session......

I actually made 2 bets (0.15+0.05), but nonetheless an incredible win.  Thank you doog for your snipe bets.  I think that boosting JD's sponsorship on pevpot is the least I can do - please sponsor some draws with this https://blockchain.info/tx-index/bed2c062bd9fff2b453cb76189ad024e47fea29d0deb5134039a6ba7a5603313.

Yeah. I actually wanted to send just 0.011* Bitcoin first. However as I am afraid that I might not be shown as Top five so I send 0.017. After sending I checked the Full sponsor page (https://www.pevpot.com/sponsors) and found out that I should wait until the last few hours before sponsoring. The good thing is that it is good to be at the top for ... a few hours days (hopefully).

* I just want to be in the "All-Time Biggest Sponsors" list.

I'm still curious about how NLNico's php code gave the right answer, if it's using openssl which has a 32 bit iteration counter? I guess I'll need to take a look at the php source code later. Anyway, the results are definitely right as my javascript check finally terminated (after 14 hours) which confirms it.

I started working on: https://www.pevpot.com/verify but it's not quite working yet. I'll finish it off tomorrow

So one thing I've been thinking about, is how to incentivize people to play at the start of the draw (as opposed the last couple of blocks).

One ideas I've had:

a) The winner gets the total amount sent to the lotto, plus X of the sponsored amount. X is dependent on the block you buy your lottery tickets, and starts off at 100% and trends towards 50% by the end of the draw? So the earlier your buy in, the higher +EV it is  (but the less known the EV) is. The later you play, the lower the EV is but the more known it is. (But regardless of when you play, it's still +EV)

b) The winner is paid 50% in BTC and 50% in next-draws lottery tickets. This would make the pot start with a nice healthy amount right from the start, hopefully attracting more players. Players would be eligible to win multiple times in a row of course. (Although it seems a little shitty to me, to pay lottery winners in lottery tickets)


Or maybe I'm over thinking it, and last-minute play isn't a problem? I just have this impression that the bigger the pot, the more attractive it is for most lottery-ticket buyers to participate.

What are your thoughts?

Im guessing option 1 is better since this will drive more people to buy the ticket faster and the pot will goes higher. As long as it is still EV+ I think the first idea is still a good option even though someone will buy in the last minute. As for option 2, Its a bad idea imo

Yeh, option b) def not. Option a) could be, I just hope it won't make it more confusing? (making it as simple as possible is the best point of the lottery.) Does it also mean that your "commission" is 0% at start and 50% at end? (not that I really care about that, just wondering.)
