Expected log hash

c1abaf0323b08bce2cedebaf1993162920ee741ace8973292e7ffdd13aca356b 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":"v1787287374804","kind":"published-quote","locale":"en","page":"theme:smallpdf/service/en","quote":"Customer service goes way further than the service itself.","rating":1,"review_date":"2026-06-11","source":"Trustpilot","source_url":"https://www.trustpilot.com/reviews/6a29ff8407e36e96f20d207c","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 (c921242d78a6…), 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.
