I had an idea about that. Publish the algorithm by which you come up with each game's multiplier. Presumably it will be seeded somehow. Pick a random seed that you will use for game 1 billion. sha256 hash it to get the seed you will use for the game before that, and so on. Each games seed is the sha256 hash of the game that comes after it. So you have a billion-long chain of sha256 hashes. Before each game you publish the hash of the current game's seed, which allows everyone to verify all the previous games but none of the future games. Now you can't be accused of rigging the outcomes.
Neat idea! Oh man, how do you expect me to fix my UI bugs when you give me such tantalizing ideas to play around with. I've got a little script generating my sha256 chain now. But it's quite an intrusive change, so I don't think I'll be able to get it live for a while.
But you still get to see, in real time, whether most people are playing the regular or inverse game, and adjust the outcomes to be mostly under 2x or mostly over 2x accordingly.
True. Although if I did that, I'd be vulnerable to someone who knew I did that, and switched.
That's always a possibility, but that needn't stop you from making the game as provably fair as possible.
Good point. I'm working on another social real time gambling game at the same time, which has the same problem -- so using a chain like that is quite appealing.
You're welcome. Thanks for the 'bits'. I managed to get greedy at just the wrong time and lost almost all of them.
hehe. Thanks man =) To be honest, I was driven out of fear that you might want to muck around with a few BTC on my site. Even though the odds are in my favor, I find the prospect of being the counter-party against your bets rather terrifying (when the bankroll is also known as my personal savings) =/
