Certificate Created: When a student completes a course, a unique certificate is generated with all course details.

Hash Generated: The certificate is hashed using SHA-256, creating a unique fingerprint that represents the entire document.

Stored on Blockchain: This hash is permanently recorded on the blockchain with a timestamp, making it immutable.

Verification: When you upload a certificate, we generate its hash and compare it to the blockchain record. If they match, it's authentic.

Tamper Detection: Even a single character change in the certificate would produce a completely different hash, instantly revealing fraud.
