🔐 Provably Fair System

Every bet on GAMBOL is provably fair — you can mathematically verify that we cannot cheat or manipulate results. Here's how it works:

1
Before your bet: We generate a secret server_seed and show you its hash server_seed_hash. This commits us to the outcome before you play.
2
Your input: You have a client_seed (customizable via /seed command). Combined with the bet ID, this ensures unique results.
3
Result calculation: The outcome is determined by: HMAC-SHA256(server_seed, client_seed:bet_id). This is converted to a number for the game result.
4
After your bet: We reveal the actual server_seed. You can verify that SHA256(server_seed) = server_seed_hash we showed earlier. This proves we didn't change the outcome!

💡 To verify: Take the revealed server_seed, hash it with SHA256, and compare to the server_seed_hash shown before your bet. If they match, the game was fair.
