Blockchain plays a significant role in supply chain management by providing enhanced transparency, traceability, and security in transactions. This decentralized ledger technology facilitates the seamless sharing of data among all parties involved in the supply chain, from manufacturers to consumers. By recording every transaction on a secure network, blockchain allows stakeholders to verify the authenticity of products and monitor their movement in real time. This mitigates issues like fraud and counterfeiting, ultimately improving trust between partners and enabling more efficient operations within the supply chain ecosystem.
