The certificate issuer -IHK- issues a digital version of the certificate as well as a paper version. The document should be archived by the issuer and made available to the graduate through a download portal. The hash value (sha3-256) calculated for each file, is stored in a Blockchain Smart Contract using an API. Once saved, data can no longer be modified or deleted.
Certificate validity can be checked by calculating the hash value again and comparing it with the values stored.
If a document becomes invalid, it can be marked as such.
