The drawing is based on the below algorithm in order to conduct it in a manner that is guaranteed to be fair and truly random.

After the lottery closes (October 13, 2013) these steps will be automatically performed.

  1. From the Block Chain, take the first Block after close date (2013-10-13T00:00:00+00:00 included); let's call this the Hashing Block.
  2. The hash of this block is completely unpredictable and it is used to generate your unique Tickets Codes:
    • SHA256(hashing_block_hash + account_label + n + hashing_block_hash) (no spaces or + sign) where:
      • hashing_block_hash is the unpredictable hash of the Hashing Block ([a-f0-9]{64});
      • account_label is the label of your Pyramining account ([a-f0-9]{8});
      • n is the counter of your tickets (0, 1, ...)
  3. The system will put online every Ticket Code for each account ([a-f0-9]{64}).
  4. Wait till drawing date (October 17, 2013) and cross your fingers.
  5. From the Block Chain, take the first Block after drawing date (2013-10-17T00:00:00+00:00 included); let's call this the Lucky Block.
  6. The hash of this block is completely unpredictable and it is used to generate your unique Tickets Hashes:
    • SHA256(lucky_block_hash + ticket_code + lucky_block_hash) (no spaces or + sign) where:
      • lucky_block_hash is the unpredictable hash of the Lucky Block ([a-f0-9]{64}).
      • ticket_code is the previously generated hash;
  7. The Ticket Hashes will be sorted 0-9, a-f and what ever hash is sorted to the beginning wins.

Do not hesitate to contact us if you think that this algorithm is not enough fair or random!

Please note that this is a beta version of the PyraLottery which is still undergoing final adjustment before its official release. Though, you do't have to worry about your Bitcoin, since we don't treat them in any way. You invest directly in Pyramining which is a stable and profitable service hosted by third party.

During this beta period, you should see minor changes only in PyraLottery related variables, such as tickets costs, drawing date, drawing algorithm, etc. We hope nothing will change, since we think that the current format is very good and profitable for every one. Though, we are not so conceited as to think that no one can propose better solutions.

Should you encounter any bugs, glitches, lack of functionality or other problems on the website or should you think that anything could be implemented in a different way, please contact us on e-mail or post in the official discussion forum hosted by

Your help in this regard is greatly appreciated.

ASICs and Pyramining queue.
The implementation of ASICs has definitely brought a benefit to the whole Pyramining community, but it has also brought some disadvantages. Currently, Pyramining accounts are not activated instantly, but must follow a queue.
Only active accounts at the close date (October 13, 2013) will be considered valid, so if you want to be sure to attend, make your deposits ​​well in advance.

Ticket cost changed from 0.001 to 0.01.
