Abstract
With the rapid development of information technology, the network system is increasingly complex, and data security has become a key problem to be solved urgently. This study focuses on the network fault tolerance mechanism from the perspective of data security, aiming to build an efficient and reliable fault tolerance system to ensure data integrity and availability. Through in-depth analysis of the existing network architecture and fault mode, combined with cryptography theory and distributed computing technology, a dynamic fault-tolerant model based on blockchain is proposed. The model can not only monitor and isolate the fault nodes in real time, but also automatically repair through the smart contract to ensure the security and consistency of data transmission. The experimental results show that compared with the traditional fault-tolerant scheme, the proposed method improves the detection accuracy by 23% and reduces the average repair time by 41%. In addition, this study also introduced a risk assessment mechanism to provide personalized configuration suggestions for different application scenarios, effectively reducing the false alarm rate and resource consumption.
