Expected log hash

0a3f75a20ca5e11e6fd9d7b6a5afa175a84aab197fa1914018652863a1a64cee 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":"v1791258637050","kind":"published-quote","locale":"de","page":"theme:canva/service/de","quote":"I really appreciated how quickly my issue was resolved","rating":5,"review_date":"2026-08-12","source":"Trustpilot","source_url":"https://www.trustpilot.com/reviews/6a7ca082106236fd9aa2d3fc","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 (3b3dd30c5821…), 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.
