Blockchain Certificate Verification
Tamper-proof academic credentials on an EVM chain
3 weeks build
Overview
Universities issue certificates as on-chain records; employers verify them in seconds by scanning a QR code. Documents live on IPFS, only hashes touch the chain, and a revocation registry handles corrections without rewriting history.
What makes it stand up
- 01Smart contracts with role-based issuing and revocation
- 02IPFS pinning with content-addressed document hashes
- 03QR verification portal that needs no wallet
- 04Gas-optimised batch issuance for whole graduating classes
- 05Full Hardhat test suite and deployment scripts
Module breakdown
- 01
Contracts
Issuer registry, credential token and revocation list.
- 02
Issuer console
CSV bulk upload, preview and one-click batch mint.
- 03
Verifier portal
Hash lookup, QR scan and validity timeline.
- 04
Storage
IPFS client with pinning service fallback.
- 05
Testing
Unit, fuzz and gas-report suites.
After this, you will be able to
- Explain why hashes, not documents, belong on-chain
- Walk through your gas optimisation decisions
- Show verification working end to end on a testnet
