Blockchain-Based Caching Architecture for DApp Data Security and Delivery

Area of Science:

• Computer Science
• Blockchain Technology
• Distributed Systems

Background:

• Centralization in traditional applications leads to vulnerabilities and performance issues.
• Decentralized applications (DApps) face performance bottlenecks with off-chain storage, impacting Quality of Service (QoS).
• Existing decentralized storage solutions like IPFS exhibit diminished download performance due to I/O constraints.

Purpose of the Study:

• To propose a novel blockchain node-based distributed caching architecture for DApps.
• To enhance the Quality of Service (QoS) by guaranteeing real-time user responsiveness.
• To ensure data integrity, user ownership, and secure content sharing.

Main Methods:

• Implemented a distributed caching architecture utilizing local cache clusters on blockchain nodes.
• Ensured cache data consistency through local blockchain data.
• Applied attribute-based encryption for secure content sharing and access control.

Main Results:

• Achieved a reduction in request processing latency of over 89% compared to existing off-chain solutions.
• Maintained cache data consistency and achieved response times within 65 ms.
• Demonstrated prevention of data leakage and unauthorized access in off-chain storage.

Conclusions:

• The proposed blockchain node-based distributed caching architecture significantly enhances DApp performance and security.
• The system effectively addresses latency issues and ensures data integrity and user control.
• This model provides a secure and high-performance solution for decentralized applications.
