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.
