[CLOSED] 150%+ Payout Raffle, Rep building thread

[personABCD]

If I do not post the winner within 5 minutes of the first BTC block's discovery after 5:00pm PST (12:00 UTC) on Thursday, June 6th, I ask that all entrants leave me negative feedback

Okay, so this will have been the third time that am running this...the first time, I was called a scammer before anyone bet and the second time I was complete idiot and I held the drawing a day late, but that is all sorted now. Maybe this time I can prove that I am able to organize something like this properly.

I would like to gain trust before trading with other users for obvious reasons, so I am holding a Bitcoin raffle where I will pay out 50% more than the total amount from bidders, plus a 0.05 btc starting prize. I simply ask that the winner leave a good review on the trust thing below my username.
For example, if 10 people buy a raffle ticket (0.005 btc), I will send 0.075 to the winner. I am, however, going to limit my contribution to 0.2 btc plus the 0.05 to start. If I sell less than 5 tickets, I will send every entrant twice what they sent.

To enter, send at 0.005 btc to 124YPLs72BiMgHkBqkL3G3Ag3TCWvWmgss (an easywallet for this raffle) and post your address so that I can prove that the winnings went out to an actual person in the thread. If you send more, you will be buying multiple raffle tickets.

EDIT: The winner will be determined using a provably fair method outlined below in the thread

EDIT: You can now view current entries and odds at https://docs.google.com/spreadsheet/ccc?key=0AmRvfLTge4DMdFFSVXVrR2R1RnNaWEJ4U05sS2FhVlE#gid=0
I will try to update this thread with the current prize amount and the number of tickets sold and to answer any questions.
Thanks

If there's no legitimate way to find out who's the winner, then there's actually no point in doing it and no one will ever trust you

Do you want to propose a system?

As I posted in your other thread:

https://bitcointalk.org/index.php?topic=219632.msg2332147#msg2332147

See also the followup post by tescomatty for some excellent ideas.

If you want, you can make this a fair and verifiable raffle.

Unfortunately, you have set up a system that seems fair but is completely unverifiable. Either you are giving free money to build a good reputation (which doesn't seem to be going very well), or you are running a puppet show and collecting all the winnings. Really there is no way for an outside observer to tell the difference.

I'm sorry to say that I didn't exactly go through all 15 pages of my last thread and didn't see your comment until now. Right now, I have a spreadsheet of all entries, but not the hashes system. What if I just had an unbiased hero member look at my spreadsheet and use a random number generator to choose the winner, then post the name in the thread?

That would certainly be a big improvement over what you have now. However I would doubt the sanity of an unbiased hero member who would be willing to do something like that. No, I think tescomatty had the right idea. If you need help with the math I'm sure there's plenty on this forum who can help you.

[personABCD]

Well, anyone else want to buy a ticket?
I have a google doc of the entries, it would be great if someone would request access and help me out with the hashing for future raffles to make it provably fair,
Thanks

If I only sold one more ticket, the payback odds would be 400%

[personABCD]

Just over 25hrs to go...Is there nobody else who wants to buy a ticket?

[hambalan]

seriously, if you want to do this right, at least implement tescomatty's idea at your other thread:

https://bitcointalk.org/index.php?PHPSESSID=2087kekjop1ojdaqg2umui9f93&topic=219632.msg2334161#msg2334161

just simply use the first block after the closing time (you may wish to edit your 1st line in red in your 1st post to reflect this)

just my two cents

I'm sorry, but I really am not understanding all of that the post
What about this (sort of based on that)
Each ticket is given a number, which equals (100/(S+1))*P, where S=Number of tickets sold and P=place which the ticket was sold, so first sold is 1, second is 2...The +1 is in there so the lowest and highest numbers will be evenly spaced from 0 and 100
Then, the winner is the person whose number is closest to the number formed by combining the last two digits of the most recent block's hash. If the number was closer to zero or 100 than the lowest ticket number, the next block will be used (or else first and last tickets would be more likely to win)
In the example you linked to, the numbers would be:
20 nikto
40 boba
60 spork
80 azrael
And the last two digits of the block would be 7 and 2, making the number 72, so azrael would win
This seems like it would be fair to me

I have updated the spreadsheet to include each individual ticket and the provably fair lucky number system I have set up.

For their help with setting up a provably fair system for the raffle, I am giving hambalan an spooranchr a free ticket, this brings the prize to 0.095

[n00ber]

I'm glad to see these changes, I'll take another 8 tickets, so I that have 10 total. Sent BTC0.04 more
 

[personABCD]

Great, the prize is now at BTC0.155 with 14 tickets sold
Anyone else want in?

[personABCD]

Okay, 18 hours until drawing...The current prize amount is BTC.155, so .07142 (odds of winning with one ticket)*.155(prize amount)=0.01107=prize if it were shared between ticket buyers. 0.01107/0.005(price of ticket)=221.4% payout, or a negative 121.4% "house" edge
Will anyone buy a ticket now?
