What are TSA certificates?

TSA stands for Time Stamping Authority and represents trusted notarization offices. With a click, Bernstein conveniently lets you timestamp your documents through their service, legally recognized in their respective jurisdictions. 

While Bitcoin certificates are mathematically valid internationally, these centralized services bridge the gap in legislations and let you secure the largest perimeter possible to protect your IP: in Europe with the Bundesdruckerei certificate, China with UniTrust, and Japan and Korean authorities coming soon. 

For example the timestamp issued by the Bundesdruckerei is compliant with the eIDAS regulation.
