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

36fb5b5862e9246d8759ca3252f3e551142d7299ce951da48aff51927774a42e = 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.
