How does blockchain help supply chain management?

• A. Improves transparency and traceability
• B. Increases production speed
• C. Reduces demand variability without data sharing
• D. Eliminates inventory entirely

Answer: (A)

Blockchain in supply chain management centers on trusted information flow. It provides a shared, tamper-evident ledger where every event—production, shipment, receiving, quality checks—gets recorded with time stamps and cannot be altered unilaterally. Because all participants access the same data, the journey of a product from origin to customer becomes visible, making provenance verification, lot tracking, and recalls much faster and more reliable. This transparency also helps deter counterfeits and supports compliance with regulations. The other ideas don’t capture what blockchain inherently delivers. It doesn’t by itself speed up manufacturing or production processes. It also relies on data sharing among partners to unlock its full benefit, so the notion of reducing variability without sharing data isn’t consistent with how blockchain enables visibility. And it won’t eliminate inventory entirely—inventory levels depend on demand, lead times, and service goals, not just ledger technology.
