The Solution: Enterprise Blockchain for End-to-End Traceability
Spundan designed and deployed a permissioned blockchain network providing immutable, shared visibility across the entire supply chain:
- Permissioned Blockchain Network: Deployed Hyperledger Fabric with 8 organizations (suppliers, manufacturers, distributors, retailers, certifiers, regulators) as network peers — each maintaining a copy of the immutable ledger.
- Unique Product Identifiers: Assigned GS1-compliant serialized identifiers (EPCIS standards) to each batch and individual high-value product — enabling item-level traceability from raw material to retail shelf.
- Smart Contract Workflows: Implemented chaincode for automated event recording at each supply chain step — harvest, processing, packaging, shipping, receiving, shelving — with cryptographic signatures from each participant.
- IoT Integration: Connected IoT sensors (temperature, humidity, GPS) that automatically record environmental conditions to the blockchain — ensuring cold chain compliance with tamper-proof logs.
- Certificate Management: Digitized all certifications (organic, fair trade, kosher, halal) as verifiable credentials on blockchain — enabling instant authenticity verification by any network participant.
- Recall Automation: Built smart contract that, when a contamination source is identified, automatically traces all affected batches, notifies all downstream partners, and triggers recall workflows within seconds.
- Consumer Portal: Developed QR code scan interface allowing consumers to view complete product journey — from farm origin, processing dates, certifications, to current location — building trust and transparency.
- Privacy Controls: Implemented channel-based data isolation and private data collections — competitors see only relevant transaction data while sensitive business information remains confidential.
