Enterprise Blockchain Supply Chain
Reduced supply chain verification time by 85% by implementing a private permissioned blockchain ledger
Developed a hyperledger-based supply chain tracking system for a pharmaceutical company, enabling end-to-end visibility of drug provenance from manufacturer to pharmacy.
85% Verification Time Reduction
95% Counterfeit Incident Reduction
50% Faster Partner Onboarding
Business Context
The traditional supply chain relied on paper-based records and siloed databases, making it difficult to verify the origin of drugs quickly. Counterfeit medications were a significant risk, and recalls were slow and inefficient due to lack of real-time visibility. PharmaTrust needed a shared, immutable ledger accessible to authorized partners.
Challenges
Data privacy among competitors
Multiple suppliers and distributors needed to share data on the same network without exposing sensitive commercial information to competitors.
Integration with legacy ERP systems
Connecting modern blockchain nodes with outdated SAP and Oracle systems required complex middleware and data mapping.
Scalability for high-volume transactions
The system needed to handle millions of scan events daily without compromising transaction speed or ledger consistency.
Solutions We Implemented
Hyperledger Fabric with channel-based privacy
Implemented private channels within the permissioned blockchain, allowing specific parties to share data securely while keeping other transactions invisible to unauthorized participants.
Custom API middleware for ERP integration
Built a robust middleware layer using Node.js to translate ERP data formats into blockchain-readable transactions, enabling automated event logging without manual entry.
Off-chain storage for heavy data
Stored large documents (certificates, invoices) on IPFS and only hashed references on the blockchain, ensuring lightweight ledger operations and high throughput.
Impact
Rapid verification of drug provenance
Pharmacies could verify batch authenticity in seconds rather than days, reducing verification time by 85%.
Near-elimination of counterfeit risks
Immutable tracking reduced counterfeit incidents by 95%, enhancing patient safety.
Streamlined partner collaboration
Standardized data sharing reduced onboarding time for new suppliers by 50%, fostering a more resilient supply network.
Tech Stack Used
Hyperledger Fabric
A permissioned blockchain framework for enterprise use, with private channels and chaincode written in general-purpose languages.
Pinata (IPFS)
Managed IPFS pinning, so files and NFT metadata stay available without running your own nodes.
Docker
Packages apps and their dependencies into containers that run the same on any machine.
React.js
The backbone of the web, shaping digital landscapes with structure and semantics.
