Maybe I should add I will give a bounty for anyone that presents a good and fair raffle idea?
Brainstorm it up peeps.
Why you do not encrypt a number, you give the encryption code to a trust member, who will be as well escrow of the BTC. Somehow each of us is getting a raffle number.
Only when raffle time is out, you give the encryption key to this trust member who distribute the BTC to winners.
Is that technically and fairly possible right ?
