Verifiable Public Distribution System — Blockchain-Enabled Grain Distribution Workflow
Transactions reach the blockchain only after multi-source physical verification — preventing fraudulent entries.
Three independent events — warehouse dispatch, transport transit, and FPS receipt — must all confirm delivery.
Hyperledger Fabric chaincode automates validation and recording with no manual intervention or override.
Every transaction is immutably recorded with full audit trail accessible to government monitoring dashboards.
