The seed decides every random event in this match. Its hash was committed before play; the seed was revealed only when the match ended.

Seed hash

28fba85bc15200ec02f02bed9e4aa39c86c0de1c528864f37bad18c36525fd64 = SHA-256 of "degen.match.seed.v1", a zero byte, and the 32 seed bytes. Checked: it matches.

Checked: the seed hash proves into the root.

To check it yourself, take the replay JSON:

1. Hash the seed as above and compare it with the seed hash.
2. Leaf = keccak256(0x00 ‖ seed hash). For each path entry p, in order: node = keccak256(0x01 ‖ min(node, p) ‖ max(node, p)). The result must equal the root.
3. Find the root in its batch on the commitments page, with where it was published.
4. Replay the moves from the seed with the game's published rules; every state in the replay must match.
