Cross-blockchain communication method and device

Abstract

The invention provides a cross-blockchain communication method, and the method comprises the steps that a first edge node of a first blockchain receives a first transaction application, and carries out the pre-verification of the first transaction application; if the pre-verification result of the first transaction application is that the verification is passed, the first edge node sends the first transaction application to a nominator node group; the nominator node group determines a target nominator node meeting a preset condition; the target nominator node verifies the first edge node and a second edge node of a second block chain corresponding to the first transaction application; and if the verification results of the first edge node and the second edge node are that the verification is passed, the first edge node performs cross-block chain communication with the second edge node based on the first transaction application. Visibly, the security credibility of the cross-chain transaction can be effectively improved, the edge node can be prevented from being maliciously attacked in the cross-chain communication and migration process, and the privacy protection of the data is improved.

Description

technical field [0001] One or more embodiments of the present disclosure relate to the field of communication technologies, and in particular to a cross-blockchain communication method and device. Background technique [0002] With the continuous development and maturity of the fifth generation mobile communication technology (5G), the development of mobile edge technology, as one of the core technologies of 5G, has attracted extensive attention from academia and industry. Edge computing technology is an extension of cloud computing. Computing services run on the edge of the network, closer to end users. Therefore, resources can be distributed to the edge of the network to provide end users with low-latency and high-speed network services. However, edge computing still faces huge problems in terms of privacy security protection and reasonable allocation of resources. Due to the heterogeneity of edge nodes, data is vulnerable to various malicious attacks such as man-in-the-...

AI Technical Summary

Problems solved by technology

Due to the heterogeneity of edge nodes, different nodes cannot communicate directly, and in the process of communication between nodes in related technologies, data is vulnerable to various malicious attacks such as man-in-the-middle attacks and eavesdropping attacks, which can cause privacy leaks or Data has been maliciously tampered with

At present, at the level of cross-chain communication solutions based on blockchain networks, there are still shortcomings such as high degree of centralization, low cross-chain transaction volume, difficult actual operation, and high communication costs.
