Provably fair

Verify fairness

The session's seed decides every reel stop. Its hash was committed before the first spin; the seed is revealed when the session ends. Each round's reel stops come from HMAC-SHA256 keyed by the seed over the round's number and the bettor's own seed.

Checked: the seed hash proves into the root.

To check it yourself, take the session's proof:

  1. Hash the seed as above and compare it with the seed hash; prove the seed hash into the root with the Merkle path (keccak256, as for every match).
  2. For each round: round seed = HMAC-SHA256(key = seed, "degen.house.round.v1" ‖ 0x00 ‖ u64be(length of the bettor's seed) ‖ bettor's seed ‖ u64be(round)).
  3. Key ChaCha20 (RFC 8439, zero nonce) with the round seed and read little-endian 64-bit words; each reel's stop, left to right, is the next word modulo 32.
  4. Read the line from the strip in the game's rules: the stops, the line and the payout must match, and three sevens win the pool.

The replay plays every spin rebuilt this way on the server from the same data, and marks any that does not rebuild as recorded.
