Every pick file is cryptographically committed to a public Git repo and signed to the Rekor transparency log before games start. Pre-game ✓ means the commit landed before first pitch — the pick was locked in. Retro means the file was committed after the fact; this still proves the file has not been altered since, but cannot prove pre-game timing. Click Verify to inspect the Git commit and Rekor entry.
How to verify the blockchain timestamp on your own
Each picks file is hashed and the hash is committed to the Bitcoin blockchain via OpenTimestamps. This proves the file existed before the first Bitcoin block mined after it was stamped — i.e., before any game that day could have started.
- 1Download both filesClick Download JSON to get the picks file, then Download OTS Proof to get the timestamp proof. Keep them in the same folder with the same base name (e.g.,
2026-02-21.jsonand2026-02-21.json.ots). - 2Open the OpenTimestamps verifierGo to opentimestamps.org and scroll to the Stamp & Verify section.
- 3Upload the .ots proof fileDrag the
.otsfile into the verification box. The site will automatically look for a matching document to hash. - 4Upload the JSON picks fileWhen prompted, also upload the
.jsonfile. The verifier hashes it and checks that the hash is embedded in the.otsproof chain. - 5Read the resultA successful verification will show a green confirmation with the Bitcoin block number and timestamp — proving the exact picks were published to the blockchain before that block was mined. Any alteration to the JSON would cause the hash to mismatch and verification to fail.
