The problem
Research by Casino et al. (2018) highlights that traditional certificate verification processes can be time-consuming and inefficient, while Obilikwu et al. (2019) discusses how advances in digital editing technologies increase risks of credential forgery. Traditional institution-controlled credential systems also limit user ownership and transparency over academic records.
The solution
I developed a decentralized verification system using Hyperledger Aries for DID-based identity management, IPFS for distributed transcript storage, and smart contracts for credential verification and revocation. The architecture separates identity, storage, and verification layers to improve trust, traceability, and credential ownership.
