Blockchain-Enabled Supply Chain Transparency Platform
TraceSafe is a next-generation supply chain management system designed to bring transparency, trust, and efficiency to the agricultural journey from farm to fork. Built for the GLYTCH hackathon.
- Immutable Ledger: All critical events (harvest, pickup, transit, delivery) are recorded on a private, permissioned blockchain.
- Smart Contracts: Business logic for batch lifecycle and certification is enforced by chaincode.
- Multi-Org Architecture: Simulates a real-world consortium with Farmer, Driver, Retailer, and Regulator organizations.
- Blockchain-Backed Certificates: Admins can issue immutable certificates for batches that meet quality standards.
- Tamper-Proof: Certificates are stored on the ledger and cannot be forged.
- Customer Verification: End consumers can scan a QR code to see the "TraceSafe Certified" badge and verify authenticity.
- Automated Auditing: The "Integrity Verification" feature instantly cross-checks the local database against the blockchain ledger.
- Tamper Detection: Detects any discrepancies in status or certification data.
- Self-Healing: Automatically syncs the local state if the blockchain is ahead (e.g., if a batch was certified but the DB update failed).
- AgriStack Integration: Seamless login for farmers using their government AgriStack IDs.
- FSSAI Compliance: Tracks and displays FSSAI license numbers for regulatory compliance.
- Profile Management: Farmers can manage their profiles, crops, and land details.
- Visual Timeline: Full history of the batch from harvest to sale.
- IoT Data: Tracks temperature and humidity during transit (simulated).
- Media Evidence: Stores images of the produce at every stage.
- Frontend: React, TypeScript, Tailwind CSS, Lucide Icons
- Backend: Node.js, Express, PostgreSQL
- Blockchain: Hyperledger Fabric v2.5
- Storage: MinIO (S3-compatible object storage for images)
- Containerization: Docker & Docker Compose
- Docker & Docker Compose
- Node.js (v18+)
