Expected log hash

34efb4ec1aab60168b83ec62d0334b8e10d9814c0de0cc0d3569d176ff20bc2d 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":"v1787152786156","kind":"published-quote","locale":"fr","page":"product:ifolor/fotogrusskarten/fr","quote":"J'ai eu du mal à commander les cartes postales.","rating":3,"review_date":"2026-06-18","source":"Trusted Shops","source_url":"https://www.trustedshops.ch/bewertung/info_X309A43086E7145E358EE1687E9DF7162.html","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 (1154a265a990…), 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.
