Let's determine the solution's components and the interactions between them that are required to implement the OBP-based solution. The following diagram depicts the high-level solution architecture:

These are the solution's components:

• OBP Dashboard provides an interface for OEU and ORS administrators/operators to perform OBP administration and configuration tasks.
• Different sets of client applications would be needed for each of the stakeholders:
  • ORS:
    • To create a student entry and insert certificate data for the student on the ledger
    • To be able to search student and certificate data
  • OEU:
    • To be able to search student and certificate data
    • To approve/reject students' certificate data
  • Student (CV):
    • To be able to view their approved certificates
    • Generate a token for a certificate verifier to verify their academic credentials stored on an OBP ledger
  • Certificate verifier:
    • To be able to verify a student's academic credentials using the token generated by the student using the OBP solution
