Expected log hash

8667b0db28913263098c19cb6387cf64b6d68b1b8f2c4242d3139d96cef5da0d 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":"v1791861703078","kind":"published-quote","locale":"pt","page":"brand:ifood","quote":"Estão cobrando iffod clube no meu cartão sem eu ter assinatura","rating":1,"review_date":"2026-09-17","source":"Reclame Aqui","source_url":"https://www.reclameaqui.com.br/ifood/estao-cobrando-iffod-clube-no-meu-cartao-sem-eu-ter-assinatura_PPQG-lLg1JIb1-7U/","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 (825dbc6ca55f…), 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.
