Verifiable Credentials (VC's) need to be issued, stored, transferred and verified and essential parts will be linked to the ARTIS blockchain.
The cryptographically signed data packages are highly secure and easy transferable. They are mostly in a JWT or JSON-LD format and through the use of Zero-Knowledge Proofs it is possible to selectively disclose information to a recipient (verifier).
General representation of a W3C standard logic for VC's
Example: You have VC from your bank and it contains a lot of personal information - now with the use of ZKPs you can select to provide only the data which is really needed for the recipient.
In case if it is needed, the validity of VC's can be checked via a registered hash on the ARTIS blockchain.
