Add pdf documents' hash on ethereum blockchain and other optional info (issuer description, document description). The document is never uploaded anywhere. It remains on your machine. Only interaction is with ethereum. The holder/verifier can check if the hash is present and see the issuer address, description(s) if any. Only the docs added opposite the issuee shall be displayed. Multiple documents can be added and verified in one go. Designed to minimize gas fees. Simple to use and intuitive.
