### On-boarding Process Overview

The GDHCN Secretariat manages the on-boarding process and applications of eligible GDHCN Participants to connect as a trusted party to the trust network. Prepared on-boarding records will be handed over to the GDHCN Secretariat with the request to process the technical on-boarding of the trusted party. An organizational and technical successful application results in a confirmation and the GDHCN Participant can connect to the trust network as a trusted party.

Starting in September of 2023, participation will be opened to other eligible participants following the Full On-boarding Process (FOP).

Starting in June of 2023 and running through December 2023, participation in the GDHCN will be open to current participants of the European Union (EU) Digital COVID Certificate (DCC) network following a Transitive Trust On-boarding Process (TTOP). The TTOP is an abbreviated version of the FOP leveraging the notion of transitive trust.
