The Problem
HR departments and background check agencies spend weeks waiting for universities to manually verify academic transcripts, while candidates lose career opportunities due to slow bureaucratic backlogs.
What I Built
Designed an elegant cryptographic verification interface where employers drag-and-drop a diploma PDF or enter a certificate hash to get instant mathematical proof of authenticity verified against an immutable blockchain ledger.
Interactive User Flow
- Step 01: Credential Hash Submission
Employer drops candidate certificate PDF or scans QR code; browser generates SHA-256 cryptographic hash client-side for total privacy. - Step 02: Blockchain Ledger Query
Engine queries smart contract registry on the blockchain to verify timestamp, issuing authority signature, and revocation status. - Step 03: Instant Cryptographic Verification
System displays green verified badge, graduate name, faculty, graduation honors, and issuing registrar public key in under 2 seconds. - Step 04: Tamper-Proof Audit Download
HR recruiter downloads a cryptographic verification certificate with blockchain block height and transaction hash for HR compliance records.
Site Map & Architecture
Verification Portal
/ (Instant Drag-and-Drop Verification Canvas)/verify/:hash (Dedicated verification outcome permalink)/institutions (Participating university directory)/docs (Developer API for HR enterprise software)
Academic Registrar Portal
/registrar/login (Multi-factor authenticated portal)/registrar/batch-mint (Bulk CSV certificate issuance & cryptographic signing)/registrar/revoke (Revocation & correction management)
Security & Compliance
/audit-trail (Public smart contract addresses)/privacy (Zero-Knowledge proof protocol architecture)
Measurable Business Impact
Slashed academic credential verification latency from 18 business days to 1.8 seconds, eliminating document forgery and simplifying international graduate hiring.
