ChainCred: Blockchain and AI-Driven Approaches for Credential Verification

Credential verification in education and recruitment faces increasing challenges due to fraud, unverifiable skill claims, and forged certificates. Blockchain and artificial intelligence (AI) technologies offer transformative opportunities to address these issues by enabling secure credential management, automated resume parsing, and authenticity checks for submissions such as code and projects. This paper presents a structured literature review of nine works in these domains. We analyze methodologies, datasets, and evaluation metrics, compare contributions and limitations, and synthesize implementable features for ChainCred, a decentralized credential verification platform. The results show that blockchain provides immutability and decentralized trust, while AI enhances automation and originality checks, creating a pathway for reliable credential ecosystems.
