Counterfeit Drug Detection with Blockchain
Manufacturers register batches; pharmacies scan to verify them
3-4 weeks build
Overview
Licensed manufacturers register each drug batch on-chain with its expiry and a hash of the batch details, and every hop through distributor and pharmacy is recorded. At the counter, the pharmacist scans the pack's QR; the app checks the batch exists, was issued by a known maker, has not expired and has not been sold past its quantity, and flags anything that fails. Runs on Sepolia or local Hardhat.
What makes it stand up
- 01Only whitelisted manufacturers can register batches
- 02Batch hash anchored on-chain, detail kept in MongoDB
- 03Custody trail from factory to pharmacy
- 04Scan check for unknown, expired or over-sold batches
- 05Local Hardhat or Sepolia with test accounts
