With the explosive growth of electronic communication data,traditional centralized storage models face numerous challenges in terms of security,reliability,and performance.Blockchain technology,with its decentralized and tamper-proof characteristics,combined with Inter Planetary File System(IPFS)distributed storage and smart contracts,offers a new solution for large-scale electronic communication information storage.This paper designs and implements a large-scale electronic communication information storage system based on blockchain technology.Through data encryption on-chain,permission management,and smart contracts,the system achieves distributed storage and real-time verification of electronic communication data.Experimental results show that the system performs excellently in terms of performance and security,with broad application prospects.
