Again, you do not show the algorithm with which you calculate results, so the game is unverifiable and therefore not provably fair.
How did an 'independent 3rd party site' know how to implement the PF without having access to the code? Very independent and third party indeed
While I generally agree that you should not need to have a 3rd party site show that you are fair, this really is the same as having 3rd party auditors do your RNG, which is the traditional model for casinos so yeah I agree, PF should be independent on your own as the players.
I admit I haven't tried to see how this works at Betcoin though. Let's see if they come back with an explanation.
We have contacted the game provider Gamebetr and following is the algorithm and instructions on how to set it up yourself. It is the same code that is on
www.provablyfair.co and we are told that the full instructions will be added to the website soon. Please let us know if you have additional questions anytime.
Provable
This package provides the means to create provably fair random numbers and provably fair random shuffles.
Installation
via composer:
composer require gamebetr/provable ^1.0
Basic Useage
// set some vars
$clientSeed = 'your client seed here';
$serverSeed = 'your server seed here';
$min = 1;
$max = 52;
$type = 'shuffle';
// instanciate the provable class
$provable = new Gamebetr\Provable\Provable($clientSeed, $serverSeed, $min, $max, $type);
// get the results
print $provable->results();
// prints [6,21,19,13,41,28,40,43,2,39,5,24,18,52,46,26,20,7,29,38,23,37,30,31,33,44,22,16,35,48,25,14,45,27,11,8,17,36,51,4,42,15,49,32,3,9,1,47,10,34,50,12]
Methods
__construct(string $clientSeed = null, string $serverSeed = null, int $min = 0, int $max = 0, string $type = 'number')
The class constructor takes the optional parameters, clientSeed, serverSeed, min, max, and type. If clientSeed or serverSeed are not provided, it will generate random seeds automatically. The min and max parameters are the minimum and maximum values of the random number or shuffle. Type is either number or shuffle.
static init(string $clientSeed = null, string $serverSeed = null, int $min = 0, int $max = 0, string $type = 'number')
The init method is just a static constructor. It allows you to do the following:
$provable = Gamebetr\Provable::init()
// returns an instance of Gamebetr\Provable
setClientSeed(string $clientSeed = null)
This sets the client seed. If no seed is provided, one will be automatically generated. The Provable instance is returned allowing you to chain commands.
getClientSeed()
This returns the current client seed.
setServerSeed(string $serverSeed = null)
This sets the server seed. If no seed is provided, one will be automatically generated. The Provable instance is returned allowing you to chain commands.
getServerSeed()
This returns the current server seed.
getHashedServerSeed()
This returns the hashed version of the server seed.
setMin(int $min)
This sets the minimum value property. The Provable instance is returned allowing you to chain commands.
getMin()
This returns the current minimum value property.
setMax(int $max)
This sets the maximum value property. The Provable instance is returned allowing you to chain commands.
getMax()
This returns the current maximum value property.
setType(string $type)
This sets the type property. Allowed values are number and shuffle. The Provable instance is returned allowing you to chain commands.
getType()
This returns the current type property.
results()
This calculates the random number or shuffle and returns it.
number(int $minimumNumber = null, int $maximumNumber = null)
This generates a random number between $minimumNumber and $maximumNumber. If no values are provided, it will use the $min and $max properties of the object.
shuffle(int $minimumNumber = null, int $maximumNumber = null)
This generates a random shuffle of numbers between $minimumNumber and $maximumNumber. If no values are provided, it will use the $min and $max properties of the object.
