Blockchain-Enabled Supply Chain Management for Authenticating Products using QR with Firebase Integration

This research work makes use of blockchain technology to eliminate forged products in the global marketplace. It establishes a secure supply chain with smart contracts and QR code authentication. Manufacturers add products to the blockchain, Sellers sell those products to the users and register the sale in the blockchain network. Users verify authenticity through QR codes. The proposed system combines the benefits of a centralized storage system and decentralized storage techniques like blockchain. Moreover, the proposed approach enables trust, safeguards against manipulation, and enhances supply chain integrity on a global scale.
