Hey mocacinno, any news in the giveaway? Did the winner send the proof? Was the prize delivered?

I'm curious how things went. Maybe others will implement this feature too, if they see that your attempt worked smooth.

Nope, he\she never contacted me, and since most applications came from throwaway addresses, I didn't keep any of them, just a list of codes and btc addresses... I do still check my mail every couple of days just in case the winner pops up

[GazetaBitcoin]

Then would you consider to pick a new winner in the following days, in case the first winner still doesn't show up?

Besides, there isn't needed the email, at least that's what I understood. The winner was supposed only to sign a message from the BTC addeess mentioned in the email. Did I understand wrong?

No, you got it correct, the only thing is: without email addresses or bitcointalk usernames, I have no way to identify the winner... If the winner doesn't check his/her ticket and/or doesn't come foreward, I have no way of contacting him/her.

Sure, I'll organize a redraw on Friday, the previous winner has had sufficient time to contact me.

[GazetaBitcoin]

Oh I finally understood.

So in this case, if a new winner will be elected, he should have kept his code, he should know its hash and he has to sign from the BTC address already emailed. But you don't have the email anymore.

Maybe reorganize the email part again? This could be a solution... I guess.

Yep, that's correct, but i won't reorganize the email part tough... Not keeping track of the email addresses was intentional. I wanted this giveaway to be as anonyous as humanly possible, so i only kept the info that could never be used to identify an individual (like an unused address or a piece of code).

The winner of the last draw has failed to contact me in a timely matter, so i'll now do a re-draw... Let's use block #621450 (we're at 621447 right now).
The winner has untill monday 16th of march to contact me with the same conditions as the previous draw.

Good luck everybody!

slot #5 wins
Contact me with the same parameters as last draw if you were the winner!

Yes, the winner was drawn 11 days ago, and since he didn't reply a new winner was drawn exactly one post above yours...

But that's not the reason you get this error message... Directly from the OP:

Basically, in order to join this giveaway, you have to be at least a full member without negative trust from DT1.

since you are not at least a full member, you are not eligible to create a giveaway code... Sorry

[blue Snow]

My mistake, I don't read carefully. Thanks for the explanation

[GazetaBitcoin]

The winner has untill monday 16th of march to contact me with the same conditions as the previous draw.

So... did the new winner show up? Or shall we assist to a new election?

No, no winner showed up... But to be honest, i'm not planning to keep repeating this draw until finally someone claims their price. It's just a keychain worth a couple bucks, it's not worth the time I put in...

I'll think about organizing it one more time next week, but if the winner doesn't show up once again I'm calling this a failure and lock the thread.

[GazetaBitcoin]

Loool! I think we can agree the situation is hilarious but also frustrating. Let's see what happens next week then Will #2 and #5 be excluded from the next try?

However, I'm curious about some conclusions after you'll draw the line. Such as - how did things go from your perspective while trying to follow the new procedure? Although there was lack of interest, the organization itself is easy / difficult? Is it recommendable for others? Can your measures really offer extra-privacy? Should them be followed (the part with 10min mail and signing a message from a BTC address)? And so on. Maybe sharing some thoughts from your perspective can help other users which will organize such raffles.

Well, it's rather hard to exclude numbers, the last digit of the hash of the blockheader is going to be completely random, and it was hard enough as it is to fill the current roster... But i have an 11 year old daughter, if #2 or #5 are hit, i'll give her a bitcoin keychain and post the pictures in this thread when she receives it

My remarks about this form of giveaway:

• It guarantees a LOT more anonimity... I have no idear which useraccounts are participating, execpt a few that did send me a PM afterwards, or used an already used btc address to include with their ticket
• The organisation is a lot more difficult... You have to generate a draw, verify tickets, create hashes, keep a sheet with codes/btc_addresses/slotnumbers, generate a raffle email, check the email,...
• I think this kind of raffle is better suited for a paying raffle, there will be more interest for this and people won't forget to check their tickets if they payed actual money for their ticket
• I'm pretty sure there were cheaters that participated with alt accounts... I received 2 pairs of emails (so 4 in total), each pair using the same template (same email provider, different address => same sex => same region for the name => same wording => same sentences => same type of address => ...). Next time i'll also ask for a hash of their firstname_lastname, no capital letters, no initials, just first and last name hashed. That way it's a little harder to cheat: if the first name and last name do not match, the price is denied... This is not unbeatable tough, nothing is stopping the cheater from using their spouse's name, or misspell their name a couple of times...

[GazetaBitcoin]

I was thinking the same: more privacy but also more difficult to organize... But I wanted to hear your words as you were (are) the organizer and you know the situation better than anyone...

So it should be done by raffles with more valuable prizes, but it's up to the organizer to try this approach.

I hope to see more such raffles in the future, at least trying to do what you did here.

[joniboini]

mocacinno is currently temp-banned as explained by him there: https://bitcointalk.org/index.php?topic=5234779.0. So, wait for him if you have any business with him.

Message verified here.

[GazetaBitcoin]

So...after the ban was lifted...any news about the winner? Or, did the prize go to your daughter?

Pls don't understand me wrong, but this try of yours may lead the way in the future raffles. Maybe you should consider writing your above mentioned thoughts also in theymos' OP for this procedure? I think it's a great idea, but maybe your words will convince others as well?!

Well... Because of the problems i had, the final raffle was delayed for a week... But sure, i'll hold it one last time. However, this time i won't disclose if the raffle winner has claimed his/her price.  It's the final time i re-run the raffle, so there is no need to publicly declare if the winner stepped up or not. If there is a winner, i hope he/she creates a new, anonymous, account and posts a picture of his/her keychain after he/she receives it... But that's completely up to him/her.

If i have time, and if there's any demand, i wouldn't mind writing down my experiences in Theymos's original thread. He made a nice system that adds a big layer of privacy, and my experience would help other's wanting to benefit from my experience, but if there's no demand, i probably won't bother (but if there IS demand, i wouldn't mind doing a writeup)

So...  Let's roll one final time:
We're currently @ block #623 591
Let's roll with block number #623 593
