Issued under schema SR-PICK-V1

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.

Technical appendix — canonical bytes & Merkle proof

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.

{"attribution":{"pick_source":"story_score","prompt_version":"top_rated_v1_2026-07-08"},"committed_at":"2026-07-13T21:10:27Z","issuer":"saturday-racing.com","predicted_at":"2026-07-08T21:13:45Z","product":"top_rated","product_lane":"ratings_sr","race":{"course":"Ayr","external_id":"rac_11989770","internal_id":2486,"race_date":"2026-07-05","race_time":"14:41"},"schema":"sr-pick-v1","selection":{"advised_odds":"5/2","confidence_final":"High","confidence_raw":"156","horse":"Conciliate","position_claim":"win"}}

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.
