HOW TO PARTICIPATE
1. Announce in this thread, how many tickets you will be buying
2. Send a private message to me with the same information
3. We will send you a unique bitcoin address to pay the tickets
4. After we get the bitcoins we will add you to the public list of paid tickets
5. When the list reaches 2000 paid tickets, we will announce the block ( it will be around 4 hours away )
Rules of the contest:
The odds of winning this raffle is 1 / 2000 (total number of tickets sold) for each ticket.
The raffle will start only if there is at least 2000 tickets registered and only after all 2000 tickets are sold.
This raffle will end on Wednesday, July 10, 2013 at 11pm GMT. If all 2000 tickets are not sold by that time, all bitcoins received will be returned to participants.
You may purchase as many tickets as you like.
Whether buying a single ticket or bulk tickets, each ticket will have its own ticket number.
The only piece of information you need to submit is your email address and your forum nickname.
Winner will be determined by the blockchain, I will announce a non-mined block number after the tickets are sold and after that block is generated, winning hash for that block will be put into a simple sha + mod(2000) calculation, it will give out a number between 0-1999.
Tickets will be numbered between 0-1999 to avoid confusion
The raffle will be decided by this python script everyone will be able to verify the winner independently:
temphash = hashlib.sha256(hashoftheannouncedblock).hexdigest()
luckynumber = int(temphash,16)% 2000
Once the results of the raffle have been verified, the winner will get remote access to the mini rig SC within one hour. If the winner wants the minirig in a different location, he/she should pick it up and arrange the shipment. Mini rig owner's identity and location will be revealed to the winner only. Hosting costs (at the current facility) for the next 90 days are paid by the current owner of the mini rig.
This raffle is not related to Butterflylabs or its employees in any way, any questions or comments regarding BFlabs or their employees should be kept out of this thread.
Once paid, tickets are refundable only if the raffle is cancelled, and in that case every ticket will be refunded, transaction fees will be paid by me.
