Digital RMB Financial Risk Analysis Based on Wireless Sensor Network and Blockchain Technology

This article primarily focuses on the energy‐saving aspect and conducts research on the wireless sensor network routing protocol. The protocol initially utilizes the OPTICS clustering algorithm to partition the network into multiple one‐stage clusters. Subsequently, cluster heads are selected for each one‐stage cluster simultaneously. Additionally, a role‐based access control model and a blockchain‐based technology, along with a user solvency access control model, are proposed based on this foundation. The role publisher assigns roles to related users and stores access control policies on the blockchain through smart contracts. The contract defines the threshold for obtaining credibility. The contract information can be viewed and verified by any service provider organization in the system, and it cannot be manipulated, which improves the security of the central bank's digital renminbi system. The central bank digital currency needs a comprehensive first‐level design to be released, and it needs to strengthen the research on blockchain technology and cryptographic technology to provide strong technical and algorithmic support for the digital renminbi. Among them, the research and development and strengthening of distributed ledger technology are very important. On this basis, a stable and secure encryption algorithm system can be constructed, step‐by‐step technical solutions and hybrid technologies can be implemented, and quantum encryption technology can be fully absorbed and the financial system of the central bank's digital system can be improved. Risk handling capabilities. In this paper, the research on wireless sensor network routing protocols and the application of blockchain technology in the digital renminbi system have improved the ability to handle financial risks.
