Following on the success of the pool with the last competition, we are having another giveaway!
This time, Avalon will be supplying and shipping a miner to each of 2 winners with this new competition.
It will be an Avalon 4.1 Machine with a 4-pin-cable x1 and an AUX x1 (without a PSU) as shown in the pictures below.
The Avalon 4.1 does 1THs at approx 600W and can be overclocked to 1.3THs at approx 1000W and underclocked to 820GHs at approx 400W
Details about the Avalon4 can be found on the bitcoin wiki: https://en.bitcoin.it/wiki/Avalon4
Valkir's review on one he just got: https://bitcointalk.org/index.php?topic=938679.0
The 2 winners will be the next 2 people who find a block, with a single mining account or mining address with between 400GHs and 50THs, between now and the 150th valid pool block - i.e. the next 36 valid blocks.
If there are less than 2 winners in the 400GHs to 50THs hash range to find a block by the 150th valid block, then instead, the last 1 or 2 people, in that hash range 400GHs to 50THs, who submits the last valid shares before valid block 150 is found, will be the winners.
If you find 2 blocks, you could win both of the prizes ... so pretending you are 2 different accounts wont be required
Now, just in case we do find any orphans in that time, the orphans will also count as winners, but orphans wont count towards the total blocks until we reach 150.
I've updated the CKDB code to display the block count on the web site, but that change wont go live until next time I restart CKDB.
Block 340240 = block # 114
I will post the winning details here on the forum in this topic and you will also need to contact me via forum PM or IRC, within 48 hours of my winning announcement, otherwise we'll move on to the next possible winner.
As before, the range is specific since I don't want 1,000 people mining with 10GHs joining just to win.
I'd prefer one person with 10THs
Also, again, ckolivas and I cannot win of course.
You will have to supply an address that Avalon can ship it to via EMS or DHL.
It doesn't have to be your own address, but it has to be possible for them to ship to your chosen address.
If you cannot do this, then the prize will be awarded to the next in line.
If you mine to an address, you'll need to sign a message with the winning address, to identify who is the contact to claim the prize.
If you don't want to supply contact details to ship it to, then the prize will be awarded to the next in line.
One last important thing - my decision on the winner is final.
If there is any confusion or misunderstanding about how the winner is chosen, I retain the right to choose who the winner is in the event of any disagreement.
