The problem
Fake degrees are a billion-rupee industry — employers today verify certificates with phone calls to registrars and weeks of waiting. This project kills the problem with cryptography: universities issue certificates as hash-anchored records on a private Ethereum-style blockchain, and anyone can verify a certificate in seconds by scanning its QR code. No central database to hack, no forged PDFs that pass inspection, no waiting. It's the #2 blockchain student search after voting systems, it's adjacent to (not a duplicate of) our e-voting page so the site owns a second blockchain keyword cluster, and the QR-scan verification demo is instant viva magic.
userUniversity
Uploads graduate data and issues certificates.
Follow the working sequence
How it works
- The admin deploys the certificate smart contract on a local Ganache/Hardhat chain.
- The university uploads graduate data (CSV); the app hashes each record and stores the hash on-chain, generating a QR code per certificate.
- The graduate's certificate (PDF + printed) carries the QR code linking to its on-chain record.
- An employer scans the QR on the verification portal; the app re-hashes the presented data and compares it with the on-chain hash.
- Match → "Verified" with issue date and university; mismatch or revoked status → clear "Invalid" verdict with reasons.
Project features
- University admin panel: issue certificates anchored on-chain with student details hashed
- QR code printed on each certificate encoding its blockchain record ID
- Public verification portal: scan QR or enter ID → verified/forged verdict in seconds
- Smart-contract revocation: universities can revoke certificates (lost, fraudulent) with on-chain status
- Tamper evidence: any alteration to certificate data breaks the hash match and fails verification
- Bulk issuance via CSV upload for a full graduating batch
- Verification audit log: every check recorded with timestamp
- MetaMask-free demo flow: wallets auto-generated for smooth presentations
What is included
- Full source code: smart contracts, backend, issuer and verifier frontends
- Deployment and setup guide (Ganache/Hardhat step-by-step)
- Project report PDF (synopsis, blockchain concepts, contract design, testing, screenshots)
- Presentation PPT for review/demo day
- Viva Q&A sheet covering blockchain, hashing, smart contracts, and verification security
- Demo script with sample university dataset and printable certificates
Advantages
- Universities issue certificates anchored on-chain with student details hashed — every certificate carries a QR code encoding its blockchain record ID.
- Public verification portal: scan the QR or enter the ID and get a verified/forged verdict in seconds — no registrar phone calls.
- Tamper evidence by design: any alteration to certificate data breaks the hash match and fails verification.
- Smart-contract revocation lets universities revoke lost or fraudulent certificates with on-chain status.
- Bulk issuance via CSV upload covers a full graduating batch; MetaMask-free demo flow and a verification audit log keep presentations smooth.
Disadvantages
- Runs on a private/local chain — public-network deployment needs real ETH and is outside demo scope.
- Certificate PDFs themselves are off-chain; the chain anchors their hashes (standard industry pattern, explained in the report).
- The identity of issuing universities is admin-managed in the demo, not tied to a national accreditation registry.
- Demo-grade UI — production hardening is out of scope.
