[0010] Furthermore, the consensus mechanisms adopted by the blockchain network are PoW and PoS.

[0011] Furthermore, the blockchain network is encrypted using SSL or TLS encryption protocols.

[0012] Furthermore, the verified data can be shared with other enterprise information systems through API interfaces or data exchange platforms.

[0013] Beneficial effects of the invention: This patented technology brings significant advantages to warehouse management systems by introducing blockchain technology and combining advanced encryption algorithms.

However, it should be noted that the described embodiment is only an implementation method of the present invention and is not intended to limit the present invention. Based on the described content, those skilled in the art can make various modifications or changes to these embodiments without departing from the spirit and scope of the present invention. For the sake of brevity, the general technical details known in the art will not be described in detail in the following description.

[0015] Example 1 This embodiment discloses a WMS data management method based on blockchain, which includes system integration and initialization, data encryption and chaining, data verification and sharing, key management and access control, data backup and recovery, and security audit and compliance inspection. These steps are interrelated and mutually supportive, and together constitute a complete implementation method of a warehouse management system based on blockchain technology. By strictly following these steps for operation and management, the security, stability and compliance of the warehouse management system can be ensured.

[0016] 1) System integration and initialization System configuration: Configure the warehouse management system according to the actual needs and business processes of the enterprise, including setting user roles, permissions, data encryption algorithms and key management.

[0017] Blockchain network construction: Build a blockchain network, select the appropriate consensus mechanism (PoW, PoS), number and distribution of nodes (set according to the amount of data and computing resource conditions), and ensure the stability and security of the network.

[0018] 2) Data encryption and blockchain Data collection and processing: Through the various functional modules of the warehouse management system, warehouse-related data is collected and processed in real time, including material entry, exit, inventory changes, etc.

[0019] Data encryption: Use advanced encryption algorithms (such as AES, RSA, etc.) to encrypt the collected data to ensure the confidentiality of the data during transmission and storage. In this embodiment, the AES algorithm is used to encrypt order information and inventory information, and the RSA algorithm is used to encrypt account information.

[0020] Data on-chain: Upload the encrypted data to the blockchain network, verify the authenticity of the data through a consensus mechanism, and add it to the corresponding block of the blockchain.

[0021] 3) Data verification and sharing Data verification: When the authenticity or integrity of data needs to be verified, the corresponding data block is obtained from the blockchain and decrypted using the private key. The decrypted data is compared with the original data to ensure that the data has not been tampered with during transmission and storage.
