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

888cca1a20f2bcfcaf945ee46f32fb93a482e11ac85ed046878e6ae511638e64 = 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.
