Project Overview
We built a private seed-to-sale traceability platform for a state-licensed cannabis client, integrating cultivation, processing, and retail data into one system. The solution was designed to meet stringent state regulatory requirements by capturing every event – from planting to sale – in real time. Traditional state systems often suffer from data silos and manual errors, so our platform provides end-to-end visibility and automated compliance reporting.

Blockchain & Traceability
Hyperledger Fabric Implementation
At the core of the system is Hyperledger Fabric, a permissioned blockchain used to validate transactions and identities. Every critical event is written to the Fabric ledger, creating an immutable audit trail.
Permissioned Access
Only authorized participants (grower, lab, processor, retailer, regulators) hold certificates
Smart Contracts
Encode compliance rules so unauthorized operations are automatically rejected
Immutable Trail
Distributed ledger is cryptographically linked and resistant to tampering
Seed-to-Sale Transparency
When a cultivator scans a batch, the transaction is submitted to Fabric and concurrently reported to the state's tracking API, ensuring immutable, transparent traceability from seed to sale.
Outcomes & Business Impact
Conclusion
This project demonstrates how cutting-edge technology solves complex regulatory challenges in cannabis. By combining Hyperledger Fabric for identity-protected ledgers, Kubernetes on AWS for scalable microservices, and Tableau for analytics, we delivered a secure, transparent seed-to-sale platform. The system not only met all compliance requirements but also became a strategic business asset – improving efficiency and building trust with regulators and financial partners.
