Regulated product integrity
DrugChain applies ledger logic to regulated product chains where every actor and contract matters. The model includes manufacturers, wholesalers, distributors, retailers, contracts and a ledger of product movement.
Actor modules
The DrugChain material shows archives and forms for manufacturers, wholesalers, distributors and retailers. Each actor can carry address, type, certificates and validity dates. This makes the chain structured before any product event is written.
Contract chain
Contracts model the authorized links: manufacturer to wholesaler, wholesaler to distributor, distributor to retailer. Ledger entries can then reference those contracts instead of becoming isolated shipment records.
Verification and alerts
DrugChain verification checks include missing nodes in the distribution chain, chains not completed after a threshold, invalid node certificates, unregistered products entering the chain and primary data discrepancies such as dose or drug-related fields. The timeline view can highlight the exact weak link.
