0.2 + BTC raffle . More info inside .

in #bitcoin8 years ago

Hello everyone , I don't think I will get any better place than this to promote the raffle . Everyone can participate. I will explain how to participate and how you can be the winner in following steps

  1. Join bitvest -> https://bitvest.io?r=19

Obtaining Tickets:
Tickets are obtained for each raffle for each 50k satoshis or tokens bet on any game. Tickets obtained with BTC betting go towards the BTC raffle, ones obtained with token betting go towards the token raffle.
The amount of tickets earned is rounded down, so if you bet a total of 99k tokens, you will still have 1 ticket at the time of drawing.

3.Prize Draw Time:
The draw will be held on July 30th GMT at a random time. We will announce this time 4 hours in advance. You will no longer be able to earn tickets after this time.

4.Determining the Winner:
We will publish a list of all users, and their tickets held once the draw time is reached.
The list will be in a format as follows:

HMAC_SHA256($Username, $UserID) = "$StartTicket to $EndTicket ($Username: $TicketCount)"

This will allow users to easily check if they are listed as expected, the list will be ordered by hashes alphabetically. The first ticket will be numbered 0.

Once this list is made, we will be no longer giving out tickets. We will then pick a target block 3 blocks from the most recent. Once this block occurs, we will wait until it is 3 blocks deep to prevent any issues with it possibly being orphaned.

We will take the first 12 hex digits of SHA256($BlockHash) for BTC, and SHA256(SHA256($BlockHash)) for TOK then convert to decimal, allowing for a number from 0 to 281474976710655 to be chosen. We will then divide this number by the number of tickets held, and keep the remainder. This will be the ID of the winning ticket. The same block will be used for both raffles
