Yes, that's correct! The paper proposes a solution that utilizes blockchain and AI technologies to ensure the secure and transparent distribution of medical drugs across the supply chain. The system employs smart contracts and a Rasa chatbot integrated into a Flutter app to enable ordering and traceability of medicines. Additionally, the system includes a blockchain-based credit evaluation mechanism to enhance the trustworthiness of the supply chain participants. The smart contracts are deployed on a local blockchain provided by Ganache, and the DApp is connected to the blockchain using Web3.js and Truffle framework. The system also includes trade chain and information chain platforms to construct an overall framework of the supply chain system. Platform interaction rules are formulated to standardize the system information exchange format and ensure the stability and efficiency of system interaction. Smart contracts are a type of digital contract that is designed to automatically execute predefined actions when certain conditions are met. In the context of supply chain systems, smart contracts can be used to facilitate and manage transactions between different parties, as well as to ensure the accuracy and integrity of supply chain information. By using smart contracts, supply chain stakeholders can improve the efficiency of their interactions, reduce transaction costs, and enhance the security and reliability of their data. The experimental results show that the proposed system is feasible and comparatively more secure than existing systems. While the system realizes the basic functions of the supply chain, it also promotes the sharing of information between participants and improves its efficiency. Summary of the text: The text discusses the application of blockchain in supply chain management, specifically for product traceability, and mentions the use of smart contracts to automate processes. The problem of drug counterfeiting is highlighted as a particular area where blockchain can provide benefits. The integration of artificial intelligence and Rasa is also briefly mentioned. The text concludes by emphasizing the need for further research and development in the practical applications and architectures of blockchain in supply chain management.
