Proxy Communication Layer for Blockchain Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current decentralized applications (DApps) on blockchain networks lack robust security measures to prevent unauthorized communication and phishing attacks, particularly in Web3 architectures, which can lead to vulnerabilities like the BadgerDAO attack where malicious transactions are executed without user consent.
Innovation Solution
A proxy communication layer is generated by a server to intercept and block unauthorized data communication between a computerized device and the blockchain network, using IP address replacement, protocol syntactic validity checks, rate analysis, and blacklist/whitelist comparisons to secure transactions, and maintain communication even when the device is offline by saving and transferring data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a direct connection is established between DApps and blockchain networks using WalletConnect protocol, then communication efficiency and user experience are improved, but security vulnerabilities increase due to lack of authorization verification
Solution Approach 1:
The patent introduces a proxy communication layer as an intermediary component between DApps and blockchain networks. This proxy layer intercepts and validates all communication data, verifying IP addresses and authorization tokens before allowing transactions to proceed. The mediator maintains the direct communication efficiency while adding security validation that prevents unauthorized access and phishing attacks.
2Reliability
If IP address replacement and data interception are implemented to block unauthorized communication, then security against phishing attacks is improved, but communication complexity and processing time increase
Solution Approach 1:
The patent implements preliminary action by pre-establishing a proxy communication layer with predefined security rules, IP address validation criteria, and authorization token verification mechanisms. This preparation is done before actual transactions occur, allowing the system to quickly validate and block unauthorized communications without adding significant processing complexity during live transactions.
3Object-affected harmful factors
If a proxy communication layer is introduced to validate and block unauthorized data, then unauthorized transaction prevention is improved, but system architecture complexity increases
Solution Approach 1:
The patent segments the communication system into distinct functional layers: the original DApp layer, the new proxy communication layer with security validation, and the blockchain network layer. This segmentation isolates the security validation logic in the proxy layer, allowing it to be developed, maintained, and updated independently without affecting the core DApp or blockchain infrastructure.
