Abstract

With the rapid development of the Internet, there are more and more ways of spreading news, and it's spreading faster and faster. This creates a lot of fake news that confuses the reader's vision. In order to construct a healthy news communication environment, it is necessary to suppress fake news and to crack down on the source of fake news, so it is necessary to trace the source of news. This paper tracks the news based on the distributed storage, decentralization and other features of the blockchain, with the technology of consensus algorithm and intelligent contract.
