Expected log hash

ea8f60b663262eef5ec0ce5a9fbc0ace913092ea47c37bdc70ac392578ea0c35 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.

{"dataset_version":"v1791541525227","kind":"published-quote","locale":"en","page":"brand:surfshark","quote":"Unfortunately, I missed the automatic annual renewal","rating":5,"review_date":"2025-12-30","source":"Apple App Store","source_url":"https://apps.apple.com/it/app/id1391782046?see-all=reviews","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 (ea9653d48be6…), 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.
