Congratulations makinilla!! You are the new owner of the website!!

I bid 5,2.

I bid 5 btc.

Less than 3 hours left to end the auction!

The last 12 hours to end the auction

25hours to end the auction!!!

I bid 4,8 BTC.

If you are the winner I'll explain that to you of course and all the other things you would like to know...

Ok, if you could explain it to me, i could pay 4.5

2.- Right now the draws are on tuesdays and fridays at 21:00 UTC.
This can be very easily changed, it is just a cron task that can be reprogrammed very easily. See examples: http://docs.embarcadero.com/products/er_studio_portal/erstudioPortal2.0/HTMLHelp/Admin/erstudioportal/erstudioportaladministratorsguide/cron_expression_examplescron_expression_examplecreates_trigger.htm

Changing the amounts of numbers in the draws would not need much effort either

1.- Could you set how often the draws would occur? (days, hours, etc)
2.- Could you change it to make it with a number plus two stars and less prize?(for example)

Thanks

OK, I'm interested. I bid 4,2 btc.

In millionsbtc.com everything is automated except from the winning payouts because we wanted to make manual checks when there was a winner: i.e. check that the winner's bet was fully legit ( check its bet's payment in the blockchain, etc).

All the other things are fully automated (two draws a week included). You would not have to do anything except from marketing (if you want) and a manual transaction when there is a winner.

What manual actions are needed to maintain the site? And how often do they need to be done? (send prizes, check payments...)

4 days to the end of the auction!!

6 days to end the auction!!

Interested people comment on the thread, apart from sending mp,
Thanks!

The are two charts in each line, one of 50 boxes, and another of 8 boxes, both of them numbered in a correlative way.
It can be considered a bet, if the line has at least 4 predictions: two numbers from 1 to 50 from top chart in a line and another two numbers from 1 to 8 from the bottom chart in the same line.


Which are the maximun and minimun bets?

At least, you must complete the bet of one of the lines, continuing with as many bets as you desire.


Which is the prize per bet?

The price of a bet is fixed to 0.01btc. The import of such bet will be added to the weekly jackpot, without any kind retribution to the bettor.

VERIFICATION

SECRET KEYS

In order to ensure that there is no way for the system to change the outcome of a draw, the secret keys used are decided ahead of time. They are not released right away, since they could be used to win draws unfairly. However, the hash of the keys are released before the draws. After the draws, the secret keys are released and users can verify that were provably fair.

HASHES

The system has a file of the hash keys that will be used for future draws. You will be able to check it online.


SECRET KEYS VERIFICATION

So that is all well and good for the hashes but those are just hashes, not the actual secrets used. After a draw has occurred the system will release the secret used. Then you can verify that the hash of the secret matches the published hash in the hash file. This demonstrates that the system used the secret it promised it would use.

LUCKY NUMBERS

This is how a draw is executed:

Resulting String = hmac_sha512(secret key, bitcoin_block_hash)

That is, the Secret Key is used as the key to an HMAC_SHA512(key, message) function. The message portion of this function (bitcoin_block_hash) is the hash of a bitcoin block chosen pseudo-randomly from 1 to max bitcoin blocks height. In order to calculate the lucky numbers, Hexadecimal Digits from the above HMAC Output are converted to Binary String. Starting from the beginning of the Binary String, 6 Binary Digits are being taken and transformed to decimal. As 6 Binary digits are taken, numbers can be 1-64 (0-63 plus 1). The numbers higher than 50 are ignored and the next 6 binary digits are taken until 2 numbers from 1-50 are obtained. After that, 3 binary digits are taken twice to obtain the 1-8 (0-7 plus 1) stars.

If the 128 HEX HMAC String is not long enough (if a 51-64 number has been obtained in every of the 6 binay digits strings used) another bitcoin block will be pseudo-randomly chosen, although this is very very improbable because there are 84 possible 6 digit long binary strings to be used.

You can verify a draw in an integrated web application.
