[0002] With the popularity of Bitcoin, its underlying blockchain technology has gradually become well-known, and has attracted the attention of governments and companies around the world. Today's blockchain technology has not only been used in the fields of finance and digital encryption , It has also begun to be applied in the fields of network security and industrial Internet of Things. The current blockchain network is built on the IP network, and the delay in transmitting blocks between blockchain nodes brings a lot of problems to the blockchain network. Security threats, many attacks on the blockchain network are implemented by using transmission delays, such as typical selfish mining attacks and double-spending attacks. In addition, block transmission delays will also affect the consensus speed of the blockchain network , but the transmission delay cannot be completely eliminated, and it can only be shortened as much as possible. Therefore, minimizing the delay of transmitting blocks between blockchain nodes has become an application for relevant institutions and enterprises to expand the blockchain A key point of the scene, which is also very helpful for blockchain security, the fast Internet Bitcoin relay engine FIBRE, which is a UDP-based protocol, is a solution for this transmission delay, which was launched in 2015 A more efficient Bitcoin relay network is developed on the basis of the proposed Bitcoin relay network. The function of FIBER is to quickly transfer blocks between blockchain network nodes, and further reduce transmission by optimizing compact blocks. data volume and network latency

[0003] At the same time, mobile communication technology has also experienced rapid iteration and development. Now, it has entered the 5G era. Today's 5G can not only provide ten times the network transmission speed of 4G, but also has the characteristics of high scalability and low latency. Through the on-demand configuration and reasonable division of network slicing technology, it can serve more business scenarios and provide more vertical and diversified services. Therefore, in order to adapt to more special scenarios, such as disaster management and battlefield reconnaissance and mobile The Internet of Things, etc., the blockchain network began to migrate from the initial IP network to the mobile communication network. The blockchain network built on the mobile communication network is called a mobile blockchain network. With 5G in the industrial Internet of Things The continuous penetration of the industry, the openness and interconnection of key industrial information infrastructure has been rapidly improved, and the new concept of "intelligent network connection" (such as intelligent network connection vehicles, etc.) has gradually formed. Due to the dual needs of business support and privacy security protection, the integration of 5G and blockchain technology has become a global hotspot in the field. However, the mobile blockchain network is also facing similar problems to the existing blockchain network. In the new generation In mobile communication networks, in order to support diversified business scenarios in different industries, it is necessary to provide customized network functions for different application scenarios according to different functions and requirements. Among them, the nodes distributed on the blockchain network are likely to be located in different slices, and the stability and failure rate of data transmission links between slices will have a great impact on the consensus convergence of the mobile blockchain network, although FIBER gives Block transmission has brought a huge improvement, but the existing methods do not take into account the impact of transmission link failures between different network slices in the mobile blockchain network on the consensus convergence of the blockchain network
