The Ayurvedic herbal supply chain is traditionally fragmented and opaque, leading to risks of mislabeling, adulteration, and non-compliance with sustainability standards.
This project delivers a blockchain-powered traceability platform that ensures end-to-end provenance, transparency, and trust from geo-tagged collection of herbs to the final Ayurvedic formulation packaging.
- Geo-tagged Collection - Farmers and collectors record harvest events with GPS, timestamps, and quality metrics.
- Permissioned Blockchain (Hyperledger Fabric) – Immutable storage of all supply-chain transactions.
- FHIR-Compliant Metadata - Standardized event bundles (CollectionEvent, ProcessingStep, QualityTest) for interoperability.
- Smart Contracts - Enforce sustainability rules, geo-fencing, seasonal restrictions, and quality thresholds.
- Smart Labeling - On-chain generated QR codes linked to every batch.
- Consumer Transparency - Customers scan QR codes to instantly verify product provenance.
