Abstract
With the rapid development of information technology, the problem of network security has become increasingly prominent, and the traditional security mechanism is gradually unable to cope with the threats such as data tampering and information leakage in the complex network environment. Network security solutions based on blockchain technology emerge, aiming to build a decentralized, immutable and highly transparent security system. This study focuses on the core features of blockchain technology, such as distributed ledger, consensus algorithms, and encryption technology, and explores in depth its application potential in network intrusion detection, identity authentication, and data integrity protection. Through the combination of theoretical analysis and experimental verification, a network security fr amework model based on blockchain is constructed, which can not only effectively resist external attacks, but also ensure the traceability of internal operations. The results show that the use of blockchain technology can significantly improve the overall security of the network system, especially in the prevention of malicious node attacks and the security of data transmission.
