Abstract: The present invention relates to a blockchain-based certificate verification system, designated as CertiChain, comprising a presentation layer, an application logic layer and a dual-storage layer. The presentation layer provides interaction for a Student, University/Issuer and Verifier/Employer. The application logic layer performs authentication, input validation, certificate issuance, verification and revocation. The dual-storage layer comprises a relational database for structured certificate information and an EVM-compatible blockchain for immutable storage of certificate hashes. A Tiered Trust Verification Protocol evaluates Issuer Credibility, Blockchain Confirmation, Certificate Age, Verification Frequency and Revocation Status to generate a composite trust score classified into High Trust, Medium Trust and Low Trust tiers. A dual verification mechanism cross-references database records with blockchain records to determine certificate validity. A multi-signature revocation mechanism requires a threshold of authorized signatures and provides a configurable grace period during which a certificate remains in a Pending Revocation state before revocation becomes effective.
