Blockchain Registration Info

On-Chain Registration Process

When you register an institution, the following happens:

  • Permanent Storage: Institution data is stored immutably on Polygon blockchain
  • Smart Contract Validation: Government authority is cryptographically verified
  • Tamper-Proof Records: Impossible to modify or delete once registered
  • Gas Fee Payment: Transaction fees paid in MATIC tokens
  • Global Accessibility: Verification available worldwide, 24/7

How Verification Works

Multi-Layer Verification Process

Our advanced verification system provides:

  • Blockchain Verification: Primary verification through immutable blockchain records
  • Database Backup: Secondary verification through secure local databases
  • Institution Validation: Confirms issuing institution authorization status
  • Instant Results: Real-time verification with detailed certificate information
  • Global Access: Verify certificates from anywhere in the world
  • Cryptographic Proof: Mathematical certainty of authenticity

Verification Methods

1. File Upload: Upload certificate file for automatic hash generation
2. Manual Entry: Enter certificate ID or hash directly
3. Student Verification: Optional wallet address for additional security
