Okay, I implemented a somewhat simple random generator. It is quite secure for now, but I will likely improve it in the future. The SHA 256 hash for the random string is:

Do you know whether the transaction hashes are totally random/uncontrollable? If so, the hashes can be added up and used for the random generator as quite easy alternative.
They are fairly random. BUT the RANDOM number for the winner has to come after all the tickets, for IF the user knows what transaction hash will win they could re-send over and over until they get a hash that wins. For mine, I wait till the tickets are in then set up finding who won.
Do you think it is secure now?

Edit: okay it is still possible for me to try and try till I win... so that's the reason to add the hash of block 1 and 2 after 0:00... =) I maybe implement that next week.

Ya, I think your getting why I use block data as well. Your hash of random data is secure against others cheating but you still could. Adding block data makes it so you can't as well.

Yes, that was actually the case Wink For me 6 * 0.03 = 0.18, bigger than the jackpot size Wink

I need 0.03 bitcoin for the transaction... But I have only 0.36 btc because of the first six times bonus... So the wait is till I get some mining cents or new tickets.
