Blockchain-based platform for tracking product sustainability metrics from source to consumer
Create a decentralized application that tracks environmental impact, ethical sourcing, and carbon footprint of products throughout the supply chain. The platform uses smart contracts to verify sustainability claims, provides immutable audit trails, and allows consumers to scan QR codes to view complete product histories. Integrates IoT sensors for real-time temperature, humidity, and location tracking of sensitive goods.
