Expected log hash

68e6afcd6c232c11ffffa818a4cc0c5faf1a86dd24e2ab2a7811fa1f4f43bec8 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":"v1787196781193","kind":"published-quote","locale":"de","page":"product:relai/bitcoin-savings-plan/de","quote":"I was not even offered the simple option to update my email address","rating":1,"review_date":"2025-10-21","source":"Trustpilot","source_url":"https://www.trustpilot.com/reviews/68f750be1c2feb678820b0e7","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 (689da4f5bb04…), 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.
