Cryptographic Immutability

Once an internship certificate is committed through the IssueCertificate function, it cannot be modified or deleted by any single entity.

SHA-256 Document Fingerprint

The digital PDF certificate is hashed using SHA-256 before ledger anchoring. Any change to text, dates, or signatures alters the hash instantly.

Multi-Peer Endorsement

Endorsements are collected across multiple organization peers under Fabric Raft consensus, guaranteeing zero single point of failure or falsification.

Frequently Asked Questions

About Blockchain Certificate Verification

When an internship certificate is awarded, a unique Certificate ID and a cryptographic SHA-256 hash of the generated PDF document are permanently recorded into our Hyperledger Fabric permissioned ledger across peer0.org1 and peer0.org2 nodes. When anyone inputs the ID or scans the QR code, the system queries the live state database via smart contract (certificatecc) to confirm authenticity in real time.
