The principles of blockchain for supply chain management include transparency, traceability, and security. Blockchain technology provides a decentralized ledger that all parties can access, ensuring real-time visibility of transactions and asset movement. Each transaction is recorded as a block, forming an immutable record that enhances accountability among stakeholders. This traceability allows for effective monitoring of goods and helps in identifying counterfeit products. Additionally, the cryptographic features of blockchain protect data integrity, reducing fraud and increasing trust among supply chain participants.
