Expected log hash

17b34089c9aa8091fa75e421b51f027dc37b50e8cb79082ca972af63c8cadbbe The log entry's spec.data.hash.value must equal this value: the SHA-256 of the Merkle root string above. Recompute it yourself from the root to confirm.

Canonical record

{"dataset_version":"v1793587696188","kind":"published-quote","locale":"pt","page":"brand:uairango","quote":"Aplicativo muito instável","rating":1,"review_date":"2026-05-01","source":"Google Play","source_url":"https://play.google.com/store/apps/details?id=com.uairango","v":1}

Verify in the public log

1. Open the Rekor entry (pre-filled with this proof's log index).
2. In the entry, compare spec.data.hash.value with the "Expected log hash" above: it is the SHA-256 of the Merkle root string (7dc417186ff7…), which ties this proof's root to the log entry.
3. Decode spec.signature.publicKey.content from base64: it must equal Citatio's published key at /.well-known/citatio-signing.json.
4. The entry's integratedTime is the independent timestamp: the root, and with it this quote, existed no later than that moment.
5. Locally, without any Citatio infrastructure: SHA-256 the canonical record (must equal the record hash), verify the Ed25519 signature against the public key, and fold the hash through the Merkle path (sorted-pair SHA-256) to reach the anchored root.
