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

6fed35ca952ec55e7becf01ac4d48d935971a46db18b1292279106116b0c12e1 = 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.
