The applications of blockchain in supply chain management include enhancing transparency, traceability, and security across the supply chain. Blockchain technology allows all parties involved to access a shared, tamper-proof ledger that records the entire history of a product, from source to consumer. This capability ensures that stakeholders can verify the authenticity of goods and monitor compliance with regulations. Additionally, smart contracts facilitate automated transactions and payments, reducing processing times and costs. Overall, implementing blockchain technologies in supply chains fosters greater efficiency and trust among participants, leading to improved operational performance.
