Research on the Application of Blockchain Technology in Network Quality Assurance and Trust Building

Abstract

With the rapid development of Compute-First Networking (CFN), network computing resources have become a critical factor in network forwarding, while the centralization defects of traditional Internet trust systems—such as single authentication methods, vulnerability of central nodes, and low scalability—pose significant challenges to network security and transmission efficiency. Blockchain technology, characterized by tamper-proofing, distributed sharing, and decentralization, offers a novel solution to enhance trustworthiness in CFN. This study aims to construct a network path quality assurance and dynamic trust evaluation mechanism for CFN based on blockchain technology. The goal is to address the centralization issues of traditional systems, improve the reliability of computing resources in network forwarding, and verify the technical feasibility through experimental validation. In the system design phase, it develops blockchain data structures, implements smart contracts, and establishes a network quality monitoring mechanism; In the algorithm optimization phase, it employs a fuzzy algorithm for dynamic node deployment and uses mathematical models (Equations 1-3) to reduce latency and optimize transmission paths; In the experimental validation phase, it simulates CFN environments in laboratories to compare the performance of blockchain and traditional encrypted communication in terms of latency, bandwidth, and reliability. Experimental results demonstrate that blockchain technology enables more effective backtracking of network states and provides better forwarding paths in CFN environments.Experimental verification confirms that this technology achieves approximately 90% accuracy for network path verification protocols under attack scenarios, surpassing existing solutions, while simultaneously demonstrating superior performance in both latency and bandwidth metrics compared to conventional encryption protocols. This research confirms that blockchain technology effectively resolves centralization issues in traditional trust systems, providing a trustworthy mechanism for CFN network quality assurance. The findings offer technical support for next-generation Internet trust systems. Future work will focus on deploying the technology in real CFN environments and optimizing algorithms for practical applications.
