This paper focuses on the blockchain - based decentralized communication network, conducting an in - depth security analysis and performance evaluation. It begins with an elaboration on the numerous problems faced by traditional communication networks in the current communication environment, thus leading to the necessity of using blockchain technology to construct a decentralized communication network. The main body of the paper explores from four aspects: the analysis of the security mechanisms of blockchain in the decentralized communication network, the construction of a performance evaluation index system, the comparison with traditional communication networks, and the challenges faced and corresponding countermeasures. The research shows that blockchain brings innovative security guarantees to the decentralized communication network, but there are also certain limitations in terms of performance. Making rational use of the advantages of blockchain technology and overcoming performance bottlenecks are of great significance for promoting the development of communication networks towards a more secure, efficient, and autonomous direction.
