Expected log hash

3b93391ec0595ab5c0ff73f2540eb1322f56c3c1302e6789c57b97c74423deaf 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":"v1792118508353","kind":"published-quote","locale":"en","page":"brand:xero","quote":"the increase of monthly subcription is abusive","rating":3,"review_date":"2026-09-01","source":"Trustpilot","source_url":"https://www.trustpilot.com/reviews/6a96a3583558647e1d7d1297","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 (42ee8ba4b974…), 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.
