Cross-Chain Edge Node Validation via Notary Groups
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cross-chain communication between edge nodes in mobile edge computing is vulnerable to malicious attacks and lacks security credibility due to heterogeneity and centralization, leading to privacy violations and inefficient resource allocation.
Innovation Solution
A cross-chain communication method that involves a first edge node validating a transaction request, sending it to a notary node group, and establishing cross-chain communication with a second edge node only after both nodes pass validation, using optimized notary schemes to enhance credibility and security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional notary schemes are used for cross-chain communication, then centralization is reduced, but node credit is insufficient and security credibility is low
Solution Approach 1:
The patent introduces a notary node group as an intermediary between different edge nodes and blockchains. These notary nodes verify transaction requests and provide credibility assurance, acting as a trusted mediator that enables cross-chain communication while maintaining security and node credit through their verification functions.
2Productivity
If edge nodes communicate directly without validation, then communication efficiency is high, but data is vulnerable to malicious attacks and privacy violations
Solution Approach 1:
The patent implements preliminary validation actions by notary nodes before cross-chain transactions are executed. The notary nodes verify transaction requests in advance, checking node credentials and transaction validity, which prevents malicious attacks and privacy violations before they can occur while still enabling efficient communication.
3Reliability
If multiple notary nodes are used for validation, then security credibility is improved, but communication cost and complexity increase
Solution Approach 1:
The patent employs multiple notary nodes for validation to enhance security credibility through distributed verification. While this increases system complexity, the use of multiple nodes provides redundant verification that strengthens trust in cross-chain transactions, with the complexity justified by the improved reliability and security guarantees.

AI summary
Disclosed is a cross-chain communication method. In this method, a first edge node of a first blockchain receives a first transaction request and validates the first transaction request; on condition that the first transaction request passes the validation, the first edge node will send the first transaction request to a notary node group; the notary node group determines at least one target notary node according to a preset criterion; the at least one target notary node validates the first edge node and a second edge node of a second blockchain corresponding to the first transaction request; and on condition that both the first edge node and the second edge node pass the validation, the first edge node will set up a cross-chain communication with the second edge node depending on the first transaction request to complete a cross-chain transaction. A cross-chain communication device and a storage medium are also disclosed.
