Abstract
With the rapid development of information technology, data security issues in network applications have become increasingly prominent, and traditional centralized architectures face numerous security challenges during data storage and transmission. To address these issues, this study focuses on blockchain technology to explore its potential in network application development and its role in protecting data security. The aim is to design a blockchain-based distributed network application fr amework that ensures secure data storage and efficient management through smart contracts and decentralized ledger technology. Specific methods include constructing a blockchain system integrating access control and encryption algorithms, utilizing consensus mechanisms to guarantee data consistency and immutability, and validating functionality and performance through practical application scenarios. Experimental results demonstrate that this fr amework significantly enhances data security while reducing risks associated with single-point failures. Moreover, the optimized solution proposed in this study effectively addresses efficiency bottlenecks in high-concurrency scenarios, providing a feasible approach for practical implementation. The primary innovation lies in the deep integration of multi-level security strategies with blockchain technology, proposing a solution that combines flexibility and robustness. This not only strengthens the system's resilience against attacks but also offers theoretical support and practical references for the design of future secure network application architectures. The research findings are of great significance in promoting the widespread application of blockchain technology in the field of data security.
