Well maybe if we publically display the database IDs of each of the tickets purchased. We then place all of these into a big box and pick one out at random live on webcam? This would help the randomness and also add a different interactive sort of scope to the lottery. But on the whole basically it is a trust thing, and I'd like to think there is still a little trust in the world. I am not here to rip people off or to take the piss. I just want to learn a little and make a little and create an enjoyable BitCoin Lottery. It is like anything with BitCoin, if you buy a cardigan on BitCoinClothes.com how can you be sure you'll ever receive it? You have to have some trust and accept not everyone in the world is out to get you. It is the same with BitCoin mining, how do you know the pool owner won't run away with all the coins? I don't know enough to be able to replicate what is on BitLotto, but the joy of BitLottery is you can pay out to an alternative wallet, great if you use an online wallet, it is small and friendly, and the people behind it and hopefully the players too all have good intentions.
