1.Client Background

A marine cargo shipping company managing international trade routes between India, Southeast Asia, and the Middle East needed greater transparency and traceability across its supply chain. The client handled sensitive goods—pharmaceuticals, textiles, and electronics—that required precise documentation and real-time container status tracking to comply with multiple regulatory bodies.

2. The Challenge

Documentation was a major bottleneck. Bills of lading, customs forms, and transit records were handled via emails and physical paperwork, often leading to duplication, fraud risk, and delays. Clients had no way to verify where their cargo was or who last handled it. Audits were slow and prone to disputes, especially in cases of loss or damage.

The company needed an immutable, decentralized system that could provide visibility, ensure document authenticity, and integrate seamlessly with existing fleet tracking systems.

3. Our Approach

Warke Technologies assembled a specialized team with experience in maritime logistics, blockchain architecture, and digital identity management. We mapped each event in the cargo lifecycle—loading, shipping, unloading, clearance, and handoff—to a smart contract. The solution also had to function with variable internet access at ports and ships, so we implemented secure offline data caching.

We consulted stakeholders including port authorities, customs agents, and global clients to ensure interoperability and legal acceptance.

4. Solution Delivered

We delivered a next-gen Blockchain-Based Cargo Tracking & Document Verification System, which included:

• Digital Bill of Lading (e-BL):
• Issued and verified via smart contracts
• Accessible by shipper, receiver, customs, and port officials
• Immutable audit trail with real-time version tracking
• Event Chain Ledger:
• Each status change (Loaded, In Transit, Docked, Cleared) logged via distributed ledger
• Tamper-proof and timestamped, accessible globally
• Container Tracking Interface:
• GPS + IoT sensor integration for location, temperature, and seal status
• Interactive voyage map with alert triggers (delays, deviations)
• Stakeholder Portal:
• Role-based dashboards for shipping agents, clients, customs, insurance
• Smart document sharing with access controls and revocation
• Offline Mode:
• Data signed on-device and synced to blockchain once internet restored

5. Technologies Used

• Blockchain: Hyperledger Fabric
• Smart Contracts: Chaincode (Go)
• Frontend: React + D3.js for map visualization
• Backend: Node.js
• Storage: IPFS for document sharing
• IoT Integration: MQTT protocol + Teltonika GPS
• Hosting: Azure Kubernetes + Blockchain-as-a-Service

6. Results & Impact

• Documentation processing time reduced by 60%, with e-BLs eliminating manual errors.
• Dispute resolution dropped by 70%, due to immutable proof of handling events.
• Container-level visibility improved, including real-time location and tamper alerts.
• Customs clearance became faster and more transparent, improving trust with global clients.
• The firm was able to secure new contracts with pharmaceutical companies requiring compliance-grade tracking.
