Case openings on the platform use a Provable Fairness system that allows any user to independently verify the fairness of each opening.
The result is generated deterministically based on predefined input values and cannot be changed after the case opening begins.
Case openings use a pair of values that users can interact with directly:
Client Seed — a client-side value that can be manually changed. Changing the Client Seed generates a new sequence of opening results.
Server Seed — a server-generated value. Before opening a case, only the hashed Server Seed is shown, and it can also be manually refreshed.
Using a hashed Server Seed ensures that the platform cannot change it after the opening starts and that users cannot predict results in advance.
After changing the Server Seed, the previous seed pair is stored and can be used to verify completed openings.
The Client Seed and Server Seed are combined into a single string.
The resulting value is processed using the crc32 function.
The random number generator is initialized.
A value between 1 and 100,000,000 is generated.
The value is normalized and used as the case opening ticket.
With identical Client Seed and Server Seed values, the result will always be the same.
Users can independently verify results by inserting the applicable Client Seed and Server Seed values into the PHP code below and comparing the generated result with the case opening shown on the website.
Locally — using PHP installed on your computer or server;
Online — via public PHP runners.
Copy the full code.
Insert the actual Client Seed and Server Seed values.
Run the script.
Compare the result with the case opening result on the website.
