Expected log hash

00d82a97e8d5da8f3bb4a78d598390d6b030eb8338f0e0735ffde6aa5047ae68 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":"v1791539060014","kind":"published-quote","locale":"pt","page":"brand:uairango","quote":"UaiRango bloqueia cadastro de novas formas de pagamento repetidamente","rating":1,"review_date":"2026-09-11","source":"Reclame Aqui","source_url":"https://www.reclameaqui.com.br/uairango-delivery/uairango-bloqueia-cadastro-de-novas-formas-de-pagamento-repetidamente_sfw00sdtehdsv9ck/","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 (47aef0bbc5d3…), 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.
