What we offer
With Cert4Trust, document issuers store the corresponding hash values – a digital ‘fingerprint’, so to speak – as well as a ‘validity stamp’ for documents on our blockchain. This makes it possible to determine, at any time and beyond any doubt, whether the document has been altered since it was issued and what its current status is.
