AUTHENTICATED
Verifying in your browser…
Hashing the pick's canonical bytes with your device's SHA-256.
This is to certify that the pick recorded below was
cryptographically committed to Saturday Racing's transparency
ledger before the race ran . The commitment is a SHA-256
leaf hash of the canonical bytes; any subsequent tampering
breaks the hash and this certificate turns red. The check
runs on the reader's own device — no trust required from us.

The canonical bytes
This is the exact JSON that was hashed. Copy it, run sha256sum on it yourself, and you should get the leaf hash above.

The Merkle proof
Each hop is a sibling hash. Your browser walks these from the leaf up to the root, hashing pairs at each step.
