Research on Public Opinion Security under Blockchain Architecture

With the rapid development of Internet technology, a large number of users on the online social network can express their opinions freely, many of which are spread wantonly without clear authenticity. Due to the lack of effective speech authenticity demonstration mechanism, some untrue speech flows into social networks, causing social panic and suppression of real speech in major events, causing great trouble to people's spirit and life. Taking blockchain technology as the core, this paper studies the public opinion security under the blockchain architecture by using its characteristics such as incentive mechanism, consensus mechanism, hard tampering and smart contract technology.
