BitLotto - best odds + best payouts + cheat-proof

I'm going to be away from my secure computer for a little bit (unexpected trip to see family) so I won't be able to update my website or pay the BitLotto Jr winners until I return. The BitLotto draw on Sept 7 will NOT be affected!! Only a few BitLotto Jr draws are affected. BitLotto Jr will continue for those who want to play.

While I'm gone, I thought it would be fun to see who can figure out the winner first each week. It also helps demonstrate how the winner can't be manipulated by anyone. Everyone should get the same answer if calculated correctly.

Each week, whoever figures out the correct winner FIRST, along with the number of tickets for that week, gets 0.3 BTC when I come back.

Each week's winner is to be posted in this thread. Not throughout the forum.

Rules:
-only one entry per person per week is allowed listing a single winner (you can't post every address to win!)
-DO NOT alter your post after you post it. Altered posts are not eligible. (check it over really quick so you don't make a silly mistake) [I'll know if you did -Maged]
-when you announce the winner you also need the total tickets so people have an idea how big the jackpot is (note that sometimes some BTC is returned for over payments or under payments so valid tickets are 0.05 or more and are the only ones counted)
-tickets go from Wednesday 00:00 til Tuesday 23:59
-tickets under 0.05 are not included and are returned
-everybody but the first person to answer SHOULD QUOTE THE PREVIOUS PERSON. This will prevent someone from quickly posting something random or just guessing and editing their post once someone posts the right answer
-whoever posts the winner's address FIRST (if multiple addresses from the same person any one of them will do) along with number of tickets correctly gets the 0.3 BTC

Tips:
-the method for calculating the winner is at bitlotto.com/details.html
-all ticket info can be found at: https://blockexplorer.com/address/1fTfE6DrBua28gY5Lb8FZYQznU5VP7rjx
-the number of tickets can be calculated in advance as the winner can't be calculated until the Mega Millions draw is done anyways a few hours after tickets are all in
-get the hash of the block that FIRST passes 00:00:00 UTC Wednesday ahead of time (blockexplorer.com will list the latest block times so checking just after 00:00:00 should quickly give you the one you need)
-if using linux to generate the SHA256 hash don't forget the "-n" so there is no newline inserted into the text

eg. say the picks were: 93c63862ef (SHA256 hash of the lucky block hash + lottery numbers)
When you look at the ticket hashes you want one that begins in 9. If none of them do, you are looking for the one that has a 9 closest to the left. Say two tickets have 9 as the second digit. Those two are then compared to see what one has a 3 that appears closest after the 9.

I'll reply here when the contest is over and I'm back!

I have access to the last time a post was edited, so I can ensure that this doesn't happen. For example, you last edited your post at X:32:29

Thanks. I'll take out that part if you are ok with me contacting you when I get home to verify that posts weren't altered?

Sure, but that part is still a good idea. This should really just be an extra security step, but it protects you from people colluding to make someone's post get the bounty.

What you should add to your post, though, is to tell people not to edit their post AT ALL once it's posted. I don't have access to edit histories, just the last edit time.

Oh, by the way, because I have the ability to edit and delete posts, I won't be participating in this, even though I've verified one of the draws in the past.

Go ya! No mods allowed! LOL. I'm sure someone would complain if any mod tried altering their post. 
BTW: Thanks for checking. It's good knowing that people are checking the winners.

@BitLotto
It appears you made a mistake when paying the winner of 10th August. It appears you accidentally sent some coins of a new entry into this weeks draw out to the winner of the previous one. There was one ticket which was purchased around 00:30 on the 10th August yet was cancelled out when you withdrew the coins in the account. I have included this in my version of the draw... although he/she didn't win anyway Tongue
