Every game result is generated using HMAC-SHA256 commit-reveal. You can verify every single outcome after rotating your seed.
Commit
Server generates a random server_seed and gives you its SHA-256 hash. You set your own client_seed.
Play
Each game result is derived from HMAC-SHA256(server_seed, client_seed:nonce:cursor). Nonce increments every game.
Reveal
Rotate your seed anytime. The old server_seed is revealed. Recompute every past game to verify fairness.
import hmac, hashlib
def verify_dice(server_seed, client_seed, nonce, expected_roll):
msg = f"{client_seed}:{nonce}:0"
h = hmac.new(
server_seed.encode(),
msg.encode(),
hashlib.sha256
).hexdigest()
raw = int(h[:8], 16)
roll = int((raw / 4294967295) * 1000000) / 10000
assert abs(roll - expected_roll) < 0.0001
return True # Fair.
# After rotating your seed:
verify_dice(
server_seed="a1b2c3d4...", # revealed
client_seed="my-seed",
nonce=42,
expected_roll=37.4821
