How Blockchain Works for Credential Verification

To understand how blockchain for verification functions in universities, we must examine the technical process. When a university issues a credential, it creates a digital record containing details like the student’s name, degree, issuance date, and institution. This record is hashed—a process that converts data into a unique, fixed-length string—and stored on the blockchain. The hash serves as a digital fingerprint, ensuring the credential’s integrity.

The Blockchain Verification Process

1. Issuance: The university generates a digital credential and records it on the blockchain, often embedding it in a smart contract for automation.

2. Hashing and Storage: The credential is hashed and stored across multiple nodes, ensuring redundancy and security.

3. Verification: Employers or other institutions access the blockchain via a public key or QR code to verify the credential’s authenticity instantly.

4. Audit Trail: Every access or modification attempt is logged, providing full traceability.

This process eliminates intermediaries, reduces verification time from weeks to seconds, and ensures credentials are tamper-proof. For example, MIT’s Blockcerts initiative uses this model to issue digital diplomas that graduates can share securely with employers.
