Abstract By constructing the blockchain of the internet rumor detection model, the self-purification and traceable mechanism of internet rumor can be formed, which plays a certain role in promoting the public opinion supervision department to use the blockchain technology to govern internet rumor and guide public opinion. Based on blockchain technology and Unified Modeling Language graph, the premise of this study is based on the analysis of blockchain properties and working method, from the outbreak period of public opinion and audit of blockchain, the fermentation period of public opinion and filter of blockchain, the proliferation of public opinion to build the detection model of internet rumor, and combined with the Internet rumors “plastic rice” simulation experiment, to verify the validity of the detection model of internet rumor for blockchain. The simulation results indicated that the blockchain of the detection model of internet rumor can ensure the security and traceability of public opinion information transmission, purify the internet rumor, and ensure the integrity of public opinion information. The similarity function of the discrimination model is a relatively approximate method, which does not consider the upper limit of information storage. Thus, due to the continuous accumulation of mining difficulty, the calculation process of the hash value can be time-consuming.
