With the rapid development and popularization of the Internet which has penetrated every industry, there have been great changes in the field of news communication. The replicability and transmissibility of Internet news and the fast-growing news quantity have brought great challenges to authenticity, reliability and credibility of news content. This paper proposes a solution to Internet news source tracing based on the technology concept of blockchain and combined with text clustering technology. Taking advantage of the distributed storage structure of blockchain and the fact that it is traceable and not easy to be tampered with, the origin and evolution of Internet news can be quickly traced.
