Sigstore Verification

MLB Picks · Friday, August 21, 2026

The Sigstore log entry below cryptographically proves that the picks file existed at a specific moment in time. The hash in Sigstore matches the SHA-256 of the picks file — meaning the file cannot have been altered since the log entry was created.

What this proves, in plain English

Sigstore is a third-party transparency log. When our pipeline ran at 2026-08-21 13:46:23 UTC, it computed the SHA-256 of the picks file and submitted that hash to Sigstore. Sigstore recorded it, then notarized the entry with the GitHub Actions identity that submitted it (visible above). The entry can never be deleted or backdated.

If we changed even one character of the picks file after this entry was created, its SHA-256 would change — and the file no longer matches the hash Sigstore has on record. That's the chain: file → hash → Sigstore log entry → identity. Anyone can independently re-compute the SHA of the picks file above and confirm it matches the hash shown on this page and on search.sigstore.dev.
