Description

Technical Field

[0001] The present invention relates to a supply chain management system, and in particular to a supply chain management system based on blockchain. Background Art

[0002] Supply chain management systems are usually based on traditional centralized databases and centralized data management methods. These systems use centralized servers to store transaction and logistics information in the supply chain and use traditional database management software to record and process data. They usually have the following disadvantages:

[0003] 1. Centralized data storage and management: Existing technologies usually rely on centralized databases and servers to store and manage data in the supply chain. This centralized storage method is prone to attack targets. Once the server is attacked or fails, the supply chain data may be lost or tampered with.

[0004] 2. Information asymmetry and traceability issues: Data exchange and verification in traditional supply chain management systems have certain information asymmetry and traceability issues. Participants are unable to fully verify and trace the authenticity and accuracy of transaction and logistics information, which can easily lead to trust issues and disputes.

[0005] 3. Data consistency and delay: Since data in the supply chain management system is transmitted and converted between different systems and platforms, there are problems with data consistency and delay. This may lead to inaccurate, delayed and inconsistent information, affecting the efficiency and responsiveness of the supply chain.

[0006] 4. Reliance on third-party intermediaries and trust issues: Supply chain management in existing technologies often requires reliance on third-party intermediaries to verify and mediate transactions and disputes between parties. This increases costs, reduces efficiency, and trust issues still exist because participants need to trust the fairness and reliability of the intermediary.

[0007] Therefore, a blockchain-based supply chain management system is needed to achieve data security and tamper-proofing, information transparency and traceability, and intermediary links and cost reduction. Summary of the invention

[0008] The purpose of the present invention is to solve the problems mentioned in the background technology and provide a supply chain management system based on blockchain.

[0009] In order to solve the above technical problems, the technical solution provided by the present invention is: a supply chain management system based on blockchain, including an RPC module, a core business module, a database storage module, a log recording module, a supply chain network module, and an operating environment module;

[0010] The RPC module includes an authorization and authentication module, a parameter verification module, and a data processing module;

[0011] The core business modules include identity registration and verification modules, financial accounting modules, and commodity procurement, production, sales, and inventory modules;

[0012] The database storage module includes a MS SQL module and a MY SQL module;

[0013] The operating environment module includes Alibaba Cloud host, independent server, and third-party virtual host;

[0014] The log recording module and the supply chain network module are connected to the operating environment module, the RPC module, the core business module, and the database storage module respectively;

[0015] The RPC module is connected to the authorization and authentication module, the parameter verification module, and the data processing module;

[0016] The core business module is connected with the identity registration and verification module, the financial accounting module and the goods procurement, production, sales and inventory modules;

[0017] The database storage module is connected with the MS SQL module and the MY SQL module;

[0018] The operating environment module is connected to the Alibaba Cloud host, independent server, and third-party virtual host.

[0019] As a preferred solution, the identity registration and verification module allows supply chain participants to register and complete identity authentication in the system. The identity information is recorded on the blockchain and its security and privacy are protected by encryption algorithms.

[0020] As a preferred solution, the supply chain network module is a decentralized supply chain network created on the blockchain, and the supply chain network module connects various participants, including suppliers, manufacturers, logistics companies, and distributors.

[0021] As a preferred solution, the data stored in the database storage module is associated with other transaction information in the supply chain to achieve traceability and tracking of goods.

[0022] As a preferred solution, transaction and logistics information in the supply chain will be recorded in smart contracts on the blockchain. Smart contracts are pre-programmed automated rules that can automatically execute and verify transactions and ensure their legality and accuracy.

[0023] The advantages of the present invention compared with the prior art are:

[0024] 1. Improve data security: Through the decentralization and encryption algorithm of blockchain, the present invention improves the security of supply chain data. Data is stored on a distributed ledger and is not vulnerable to attack or tampering, ensuring the integrity and confidentiality of the data.

[0025] 2. Enhanced information transparency: The blockchain-based supply chain management system provides higher information transparency. All participants can view and verify transaction and logistics information in the supply chain in real time, eliminating information asymmetry and trust issues, and promoting cooperation and trust among participants.

[0026] 3. Improve transaction efficiency: The present invention introduces smart contracts to improve transaction efficiency by automating and executing contracts and transactions in the supply chain. Smart contracts can automatically trigger and execute various operations, reduce intermediate links and human errors, and improve transaction speed and accuracy.

[0027] 4. Realize traceability and tracking: Based on IoT devices and blockchain technology, the present invention realizes real-time monitoring, traceability and tracking of the supply chain. IoT devices can collect and transmit logistics data, and supply chain participants can accurately track the process and source of products, improving traceability capabilities and product quality management.
