Your "Provably Fair" System is Only Half-Fair.
Why should players trust a Server Seed generated by the house? They shouldn't.



The Industry Problem:
Standard "Provably Fair" systems (Server Seed + Client Seed) have a fundamental flaw: The house knows the server seed before the player places a bet. Even with a hash commitment, a malicious operator could pre-generate billions of seeds to find ones that favor the house against common client-side patterns.

The Solution: Blockrand API
Blockrand introduces External Entropy into your game loop using the Drand Beacon.

  • Phase 1 (Commit): Player bets; your game commits (with Player and Server Hash) to a future Drand round.
  • Phase 2 (Wait): A 10-second window. The number literally does not exist yet on any server.
  • Phase 3 (Reveal): The threshold cryptography network broadcasts the seed. The result is revealed.


Battle-Tested & Production Ready
We recently stress-tested this on Hacker News (reaching #1).
  • 90% Retention: Proof that players prefer a 10s wait for 100% transparency over instant "trust-me" rolls.
  • High Uptime: Handled 500+ rolls from multiple users with zero lag or failures.
  • Fair Distribution: Verified hex-spread across all test bets.


THE OFFER: Free Managed Integration
I am looking for 2 active casinos or game developers (Dice, Crash, Coinflip) to be our anchor partners.

What you get:
1. Free API Access: High-limit access to the Blockrand randomness engine.
2. Hands-on Support: I will personally help your dev team with the Go/JS integration.
3. Trust Badge: "Powered by Blockrand - Externally Verifiable" to put on your UI.

In theory this sounds great but you have some issues.

1. 10 second wait between bets. Some players are going to be 100% fine with that wait to get results while others are going to dislike the wait. I prefer faster rolls, but would be willing to compromise if truly fair.

2. Any casino open to implementing this would most definitely want to inspect the code before applying it to their site to make sure no backdoors are there to steal the bankroll or compromise their server.

3. Let's assume casino's are using salted seeds and fucking players over pre resulted seeds to screw a player based on their betting tendencies, do you think a casino is going to want to move to a system that they cannot control the result? They're making money hand over fist in the big markets, IDK if they're cheating or not. I'd love to find out, but they're not gonna allow me to bring in a dev to check their code.

Idk whether someone takes you up on this or not but I'd love to hear some of the communities thoughts.

Thanks for the honest feedback, @yahoo62278. Here’s how I’m looking at those three points:

1. The 10s Wait: You’re right—it’s a trade-off. We see this as the "High Roller" or "Transparency" tier. It’s for players who prioritize certainty over speed. Interestingly, our early data shows that the 10s wait actually builds "suspense" that players enjoy, similar to a physical roulette wheel slowing down. It’s a different psychological loop than the "instant-loss" of a 1ms roll.

2. Verifiability vs. Backdoors: I 100% agree on the need for transparency. The client-side integration (JS SDK) is Open Source and available on GitHub for anyone to audit how commitments and reveals are handled. Because we use Drand, the system offers Black-Box Verifiability. Even if a casino (or Blockrand) wanted to cheat, we cannot forge the Drand pulse. The integration is a stateless API call—we never touch the casino's bankroll or private keys.

3. The "Control" Issue: This is the elephant in the room. Honest casinos spend thousands on marketing to prove they aren't cheating. Blockrand gives them a way to prove it without anyone needing to "trust" their dev team. As for the giants making money hand over fist? They might stay with their black boxes. But for a new casino trying to steal market share, offering "Double-Blind" fairness is a massive competitive advantage.

I'm looking for 2 anchor partners to trial this for free and prove that players actually value this level of transparency.

In theory this sounds great but you have some issues.

1. 10 second wait between bets. Some players are going to be 100% fine with that wait to get results while others are going to dislike the wait. I prefer faster rolls, but would be willing to compromise if truly fair.
