Quote verification

This proves the quote below is recorded by Citatio exactly as displayed and has not been altered since it was committed and anchored. It documents Citatio's crawl observation; it does not imply endorsement by the source platform. The quote links to the original review.

“Was ich am meisten an Meteomatics mag, sind die hochpräzisen Wetterdaten und die direkte Integration des einfach zu bedienenden APIs.”

Expected log hash

6c785387604f7a22a5b096fa3c6c8cb93055a92b2f2f24f3a0a42c9bae32debd 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.

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 (5281b854216b…), 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.
