Sorry man, if you're honest - I appreciate the effort. If you're a scammer - then fuck you, too! :)
Problem is, we can't really tell which is the case until it's over, and it's really the game maker who decides when it will be "over".
>Do you have any additional technical mechanisms by which we can ensure the contest is conducted fairly?
Yes. I make wallets Alpha and Omega and keep the knowledge of the right solution all to myself.
See the problem now? You'd have to trust me not to attempt to use that info to claim other people's money.
And even with a "committee", I see it going wrong as someone could come with the right solution but bullshit invented way he got it - wasting everyone's time and energy and making room for a lot of FUD. And it would all depend on me keeping the solution to myself. Problem is, that fairness requires "proof of not knowing", which is impossible to produce.
You say you're a math bachelor. Then you should be well aware that it's impossible to get the right address without the game maker leaking the info. If A+B+C = X, and I tell you the X, can you find A and B? Didn't think so. To determine the address is basically the same kind of problem.
As long as you offer only your money, I see no problem with the game. And there's no way you can lose the money unless you get hacked or leak the solution for whatever motive. Good PR, that's all.
>All solutions were PUBLICLY SUBMITTED FOR ALL TO SEE. If someone had submitted a correct solution, there would have been no way for me to hide that fact.
That's not the problem I point out. That "someone" could be you or your assistant - and that's the real problem. If it's your money in the reward pot, it doesn't matter. If it's community money, that risk is another story.
>It's a theoretical possibility that I'm a scammer, but to say it's "likely" is beyond bullshit. Fuck you.
Ok, I understand why you might be angry. However, emotions don't change the facts and facts are:
On the first challenge, it was only the game maker funds at risk and he was at 0 risk of losing them, considering how stealth addresses work.
The whole way the 1st game is set-up is overly complicating what the game essentially is: I tell you the output, you tell me the address it was sent to. Sure, thanks to all the gimmicks it made a good PR impact among many who don't understand technical details of how Monero works. Even if the author revealed the final TX it would still be impossible, but then the game would not look as interesting.
Nobody submitted the answer to the 1st game (well, of course - since it's impossible).
Game maker now tries to raise money from other people, propping up useless (useless for this purpose, not in general) gimmicks like GPG signatures and multisig, all to make people feel more safe, while avoiding to deal with the real liability here: him being the one who knows the right answer.
For the 2nd challenge, it would be a big pot of money which could be claimed by whomever gets the info from game maker. Since it's not anymore only his money, game maker has monetary incentive to collude with someone and claim the reward himself.
The panel/judges may be able to prevent someone from taking all the money, but at the expense of potential drama if someone who claims the reward comes up with some BS invented explanation and then the discussion drags forever and generates a lot of FUD.
Yes, I say "sophisticated scam" because it's impossible to tell it's a scam until it's over. And with rolling reward it would only build trust while making the prize bigger and bigger at the same time.
