A decentralized anti-counterfeiting system. Brands register products as smart contracts. Consumers verify authenticity by scanning a QR code — no middlemen, no trust required.
Manufacturer registers their brand. System generates a unique smart contract address stored on-chain.
Each product ID is added to the contract mapping. A QR code encodes the contract address.
Customer scans QR code. System queries the blockchain — returns Authentic or Counterfeit instantly.
