原文外掛簡介
Clockdo helps WordPress site owners protect their publish date by generating a verifiable content timestamp.
When your post goes public, Clockdo creates a deterministic fingerprint (SHA-256) and requests an OpenTimestamps proof. This allows you to independently verify that your content existed at a specific time — useful for documentation, plagiarism disputes, and publish date verification.
Features
Generate per-post timestamp records
Request OpenTimestamps proof
Export .ots and manifest files
Optional public meta tags and post footer with verification link
Independent verification using standard tools
Use Cases
Prove when an article was first published
Add a visible publication record to your posts
Protect against plagiarism disputes
Maintain an independent timestamp history
Provide verification material for disputes or takedown cases
English (Summary)
* Generate per-post records and proof history in the dashboard.
* Save proof artifacts to your WordPress uploads folder.
* Optionally inject public meta tags and/or a “Verify” footer link.
* Proofs are designed to be independently verifiable with standard OpenTimestamps tools.
Privacy
This plugin may collect and store:
* WordPress post metadata (post ID, URL, timestamps),
* deterministic hashes (SHA-256),
* proof IDs/statuses,
* proof artifacts written to local disk under wp-content/uploads/clockdo-ots-private/.
Outbound requests:
* This plugin connects to a remote timestamping API (configured by you) to request proofs.
* Depending on configuration, it may upload manifest.json and/or export.json (which can include post title and content).
Public disclosure:
* If you enable meta injection or public verify links, your public pages may expose a hash/canonicalization identifier and a verification link.
