The technology that allows for blockchain-based solutions in supply chain management includes distributed ledger technologies (DLT). Blockchain provides a secure and transparent way to record transactions, ensuring that all parties involved in the supply chain can access immutable data. This enhances traceability, accountability, and collaboration among stakeholders while minimizing fraud and errors. By implementing blockchain in supply chains, organizations can streamline operations, reduce costs, and establish greater trust in the handling of products and tracking of transactions.
