The rapid digital transformation in education has amplified the demand for secure, verifiable, and student-controlled identity management systems. Traditional identity models, dependent on centralized authorities, face challenges of privacy breaches, data silos, interoperability gaps, and administrative inefficiencies. Blockchain-based decentralized identity (DID) frameworks provide a disruptive alternative by enabling self-sovereign identity, cryptographic security, and tamper-proof verification mechanisms. This manuscript investigates the application of blockchain-enabled decentralized identity systems in education, with a particular focus on student credential verification, transcript management, cross-institutional mobility, and regulatory compliance.
The study synthesizes theoretical foundations, existing literature, and practical deployment cases to evaluate the potential of DID in streamlining admission procedures, preventing credential fraud, and promoting global recognition of qualifications. Methodologically, it combines conceptual modeling with statistical analysis of adoption readiness among educational institutions and simulation-based experiments to assess system scalability and resilience. The results demonstrate that blockchain-based identity networks outperform conventional models in terms of trust, data portability, transparency, and fraud prevention, while also presenting new challenges related to governance, interoperability, and scalability.
Simulation research indicates that DID frameworks reduce verification latency by 45%, lower credential fraud incidents by 60%, and enhance cross-border recognition efficiency by 72%. The findings highlight blockchain’s capacity to redefine educational trust ecosystems, offering self-managed digital identities that empower learners while reducing institutional overhead. However, unresolved concerns regarding legal frameworks, standardization, and infrastructural readiness must be addressed to realize large-scale adoption.
This research contributes to the evolving discourse on educational technology by providing a comprehensive evaluation of decentralized identity models, emphasizing their transformative potential in reshaping student-centric and globally trusted digital education ecosystems.
