Timestamp verification

Timestamp verification tool

Welcome to Patamu's timestamp verification tool which allows a rapid check of the timestamp validity.

In order to check validity of a timestamp follow these steps:

select the .zip archive created by the system, containing the work and the declaration of authorship
select the timestamp proof: either a single .tsr file, or — if your account has Double Timestamp enabled — the timestamps .zip bundle downloaded from your artwork page
click on "Check" button and wait for the result

This tool only works with files downloaded from your Patamu artwork page exactly as provided. Renaming the archive, the timestamp proof, or the timestamps bundle will cause verification to fail.
