A cross-blockchain communication method and device

Abstract

The present disclosure provides a cross-blockchain communication method, the method includes: the first edge node of the first block chain receives the first transaction application, and pre-verifies the first transaction application; if the pre-verification of the first transaction application The result is that the verification is passed, and the first edge node sends the first transaction application to the notary node group; the notary node group determines the target notary node that meets the preset conditions; the target notary node applies to the first edge node and The second edge node of the second blockchain corresponding to the first transaction application performs verification; if the verification results of the first edge node and the second edge node are both verified, the first edge node based on the first transaction application and the second edge node Nodes communicate across blockchains. It can be seen that this disclosure can effectively improve the security and credibility of cross-chain transactions, and can ensure that edge nodes are not maliciously attacked during the cross-chain communication and migration process, increasing data privacy protection.

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.
