jerks

lol

I'm going to copy your idea nearly word-for-word and post it in this exact subforum, but without charging commission. I will then see how long it takes for thread to be recognized. This is experimental and I will never do this again, and yes, I know I'm a douche.

no you're not a douche. thank you

This post confused me. Are you saying that I'm not a douche or that I won't post it? Because it's a little late for the second option.

You shouldn't use a single address, as anyone can watch the wallet on blockexplorer and claim the ticket purchases.

so PM the address?

That's why i said send at the same time you PM me, have two windows open

who expects someone to watch blockchain all day or all week for a 1btc prize

I'd rather just not enter if someone can steal my entry because they're faster to post than I am. ^^

okay, if you'll buy one I'll make private, unique addresses just for you, oh wait did that, now you have to buy one :)

Thanks to Luceo (https://bitcointalk.org/index.php?action=profile;u=59824) for buying the first two tickets

Looks like topic was moved...joy, probably less traffic up in here now

Free bump...what can I say? ;D

Ill buy 2...What the hell, why not.

Why not? Because I could be a spammer. I could have spent 5 days, 14 hours and 27 minutes logged in just to scam 1BTC ($10) off you guys.

got the PM, thank you

EDIT: added to list

I'm in for 3

great, i just PM'd instructions, right before i saw your PM to me :P

EDIT: Yay

now these are selling like hot cakes

if sell the last 3 today (august 31) the raffle will be decided on September 1!

I was curious about the randomness of your method so just for fun, I crawled their site and created a distribution:

Last digit : frequency
0:213
1:227
2:203
3:222
4:223
5:191
6:207
7:214
8:205
9:219

Would a decent method be to look at a block that will be mined in the future, and use the last digit in it's hash? For example block #1337

http://blockexplorer.com/b/1337


Has the block hash of 000000008bf44a528a09d203203a6a97c165cf53a92ecc27aed0b49b86a19564 which ends in 4

my method is fine and random

I suggest you specify a exactly period of time, e.g. "after 31/08/2012 23:59". Once you do it, publish here and I will hash your terms to settle the winner.

From my understanding, the share number is completely independent to the mining pool, and it's calculation isn't publicly available. Is that correct or am I mistaken?

In the case that my understanding is correct, couldn't the following happen?:

• Pool operator entirely fakes the share number to rig a contest
• Pool operator only displays a fake share number on their website  (but uses the real one in the distribution calculations)
• Pool's website is compromised by an attacker and displays a fake share number
• The pool shuts down (so there is no share number). Whatever you chose as a replacement, wasn't agreed upon when the users entered the drawing.

you guys are maker it harder than it needs to be. First post had all info

ALL TICKETS SOLD


Result will be determined by september 1st according to the first block solved by OzCoin.net pool as evident on here:
http://ozcoin.net/content/block-history-bitcoin

Not sure what their time zone is but don't matter, as it is still not 9-1-12
I will get up between 9-11AM PST to give reward

Of course anyone can figure out the winner by tomorrow if they're up first
and if the winner is up just PM me your reward address and/or post here

Then post here when you receive to prove I'm a legitimate raffle runner

I wasn't saying your method didnt work or trying to change your method I was curious if my method is sufficiently random. If someone can guess the next block hash we're screwed anyhow so it seems like a good source of entrop.y

WINNER: kayrice

CONGRATULATIONS ON YOUR LUCK!
