As I like the concept, here is an unique bid auction (with ESCROW and provable fairness!).
The rules are as follows:
You reserve as many numbers as you want to, any positive integer will do (1, 2, 3, 4... and so on). Reserving each number costs 1 mBTC (0.001 BTC). You can even reserve the first 1000 integers if you wish, at the cost of 1 BTC.
Make the payment and send me the numbers you wish to reserve. Just pay me for as many numbers as you'd like and send me a list of numbers, such as "1, 2, 3, 9, 10, 12". If you have doubts regarding fairness, you may instead of giving me the numbers, just create a SHA-256 hash of a string with the numbers you chose and a password-like part at the end, that only you know. Then, after I have published all the results, those who sent hashed numbers will reveal their numbers. For the secret part, do not use an actual password as you must publish it. This is not easy, but makes the game provably fair as I, or nobody else, will be able to tell the hashed numbers before the game ends.
Trying to cheat by editing you message with the hash to a winning one after the game ends will not work, so please do not try.
But when doing this, please pay attention: you must be able to give the proper string for others to verify it gives the correct numbers. You must also take responsibility for paying the correct amount. If you paid for n tickets but have more in your list, only the n smallest will be counted. Refunds can not be given as this would enable cheating. So please, make sure you can replicate the hash.
Those who publish hashes, will have three days to publish their secret string after I have published the non-hashed bets for all. After that period, you can not claim your winnings any more. Everyone who publishes hashes will be notified by private messages, when the three-day period starts.
The person who has reserved the smallest number that no one else has reserved, gets his money back and wins 80 % of the money others have put in the game.
Game will end on the last minute on June, UTC+0. After that there is one day left to send any numbers that have already been paid for and then I will publish the results for non-hashed numbers. After that, there is a three-day period to wait for the hashed string submitters reveal their strings. Stats will be published on the number of reservations while the game is still on; I think this makes the game more interesting.
Just send me a message with the numbers you want and I will send you the address where you can pay. If you have any questions, ask them and I will update the post under this one, that has all the stats.
As for me, well, I'm an old member as you can see, I've been on the forums for more than two years now and I have no intention to scam anyones money. I can also reveal my real-world identity to some trusted member who asks for it. Edit: I accept escrow, a trusted escrow with the nick monbux will handle it.
In short
1. Decide on the numbers you want to get
2. Decide, whether you will trust the privacy of the private message system and my honesty
2.1 If you choose to trust, ask me for a payment address and after paying send me the numbers
2.2 If you want to be cautious, ask me for a payment address but instead of sending me the numbers, publish in this thread the SHA-256 hash of a string that contains
your numbers unambiguously, including a secret password-like part. Be sure to come back to reveal the string! I will PM you about it.
3. Read and understand the rules and wait for the results!
Why is it fair?
The game is fair because of the hashed numbers. They are published ahead of time and they are here for all to see. I can not know what they contain, nor does anyone else but the person who sent them in. Also, they can not spoof the bets - creating a known SHA-256 digest (hash) from a string that was not the original one would be an almost miraculous feat and if someone could do that, they would have better applications that cheating here. It is secure. I expect that the majority of the bets will be hashed, so that knowing the plaintext bets give less of an edge (that I would still not use in any case).
So, everyone's bets will be secure until the round is over. The game is simply closed after that. The unhashed bets will be published after the game closes but before the most crucial, hashed bets are revealed. I can't manipulate the result at that point when everything is public, nor can anyone else. If anyone wanting to participate feels this is inadequate, please reply to this thread and tell me.
Have fun you all and win big! If you notice flaws in the system, please let me know.
