Call for Collaboration: Reverse Engineering a "Provably Fair" Online Casino Game

DaddyDecrypt - Aug 10 - - Dev Community

Greetings,

I've recently come into possession of the JavaScript code behind a "provably fair" online casino game, which claims to use a verification system involving client and server seeds. After a preliminary analysis, I believe there's more to this than meets the eye.

The game is governed by a colossal 50,000 lines of code, which includes the logic for several other "provably fair" games on the website. Initial observations suggest the casino may be relying on a Pseudo-Random Number Generator (PRNG) rather than a truly random system. I've successfully developed a script that can accurately predict the first outcome based on the provided data, even without cracking the hashed server seed. This indicates the real challenge may lie in deciphering how the game's timing mechanism influences the randomness of subsequent outcomes.

Objective:

I'm seeking to collaborate with skilled programmers, mathematicians, and cryptographers to:

  • Deepen our understanding of the game's algorithm.
  • Isolate and analyze the timing component, if it exists.
  • Develop a third-party verification script capable of predicting multiple future outcomes.

My Hypothesis and Approach:

I have an idea that if a timing mechanism is indeed in play, we can leverage the provided data (server seed hash, client seed, and the nonce found in the game code) to write a JavaScript script. This script, combined with automation tools, could predict the outcome at a specific future time. We can then automate the action on the site to place the bet at that exact time, ensuring our predictions align with the actual game outcomes.

Security and Privacy:

For obvious reasons, I will withhold sharing the name of the site in this thread. Only those who prove they have the qualifications to assist will receive the information. I'm looking for trustworthy people to join this effort.

Current Challenges:

After grabbing the JavaScript, I checked my DNS logs and noticed I was suddenly being watched by an admin from a certain domain. This suggests I tripped some alarms. Since then, I've been unable to accurately reverse verify game outcomes on the site. I’ll need some help getting around this obstacle.

Potential Rewards:

If we succeed, there are rewards from an obvious source that we can share. This is not just about proving the fairness of the game; there's a tangible incentive involved.

If you're intrigued by the challenge and possess the necessary expertise, I invite you to join this collaborative effort. Let’s unravel the mysteries of this system together and create a robust verification tool that can truly test the fairness of the game.


If you’re interested, feel free to reach out so we can discuss the details and next steps.

Best regards,
