Description

A working prototype built on Hyperledger Fabric with 4 peer nodes belonging to four different institutions. It implements four core smart contracts—EnrollmentContract, AssessmentContract, CertificationContract, and IdentityContract—covering "course registration, automatic grading, certificate issuance, and decentralized identity management". The on-chain data model includes StudentProfile, EnrollmentRecord, GradeRecord (preserving all regrade history), and Certificate records; large content such as feedback text is stored off-chain with hashes on-chain.

Design Implications

Context

Requirements

  • Instructor identity must hold restricted grading permissions for grade records to be accepted by the contract

Constraints

  • The prototype does not include a fully functional user interface; interactions are scripted to represent multiple users and actions
  • Grading used simple keyword matching against an expected answer rather than a full AI grader

Target Learners

  • online higher-education students

Learning Goals

  • enrollment, assessment, and credential workflows with verifiable records
