I need a programmer to make a website like [login to view URL] , [login to view URL] , [login to view URL] where some random steam players put skins who worth somes $(the higher the value the player bets, the higher the chance he wins the jackpot - ) or more and when the pot hits at least x (definable via config or admin backend) entries or 5 minutes the system randomly selects one player and all the skins of guns in counter strike global offensive is awarded to him through steam trade offer. This would be using Steams Trading Link system and steams api login.

I'll also need a bot (i'll be able to give you a bot coded in node.js that got a lot of bugs for make you understand what i need )who will accept all the offers that come from the users , and at the end of a round will send the winnings to the winner.

Parameters that need to be set via config: Number of entries to calculate the winner, house edge in percent to keep after every round.

Provably fair system of the jackpot:

There are three elements that allow you to verify that a round was fair, they are:

The winner percentage

The winner percentage allows you to discover the winning ticket number.

To uncover the number the system uses the formula floor( ( NumberOfTicket - 0.0000000001 ) * ( (WinnerPercentage / 100) ) ), where the floor function rounds a number downward to its nearest integer.

After doing the math you'll end up with a integer that contains the number of the winning ticket, from there you will only need to count the number of tickets, starting at the beginning of the round (being that we give 1 ticket per each 0.01$ deposited) and you'll find the fair winner - please note the fair winner is zero based, so the first ticket starts on zero, and goes from there (in the example bellow we are already incrementing the ticket number for you).

The round secret

The round secret is generated at the beginning of the round but only shown at the end, and it's meant to encrpyt the winner percentage and allow you to verify the winning ticket via the round identifier.

The round hash

The round hash is an md5 string that is given at the beginning of the round, it is generated by joining the round secret with the winner percentage, separated by a "-", so a round hash is an md5 encrypted string of "[roundSecret]-[winningPercentage]".
