How to Implement a Blockchain-Based Provably Fair Casino Game?

Question-
How can you implement a provably fair gaming mechanism using blockchain hashing?

Challenges Faced-
Generating deterministic but verifiable randomness.
Allowing players to verify fairness without exposing results beforehand.
Ensuring transparency while maintaining security.

Solution-
Use SHA-256 hashing to create a provably fair seed:

python

import hashlib

server_seed = "CasinoSecret123"
player_seed = "PlayerBet456"

combined_seed = server_seed + player_seed
hashed_result = hashlib.sha256(combined_seed.encode()).hexdigest()

print("Provably Fair Hash:", hashed_result)
Enter fullscreen mode Exit fullscreen mode

🔹 Why this works-

  • The server commits to a secret seed before the bet.
  • The player provides an independent seed.
  • The result is generated after both are combined, making it verifiable.

And it seems that there are even crypto casinos now that offer not only classic gambling games like slots and others but also some unique games that work based on the Provably Fair principle. It sounds interesting. I even searched where to find such games, and many recommend Fortunejack. It turns out that this casino has actually been around for quite a few years, has a good reputation, and offers the ability to work with various cryptocurrencies, not just popular ones like Bitcoin and Ethereum.
