This paper utilizes the meta-universe scene construction technology to build virtual and real environments that serve learning and provide new paths for learning development. The construction basis of three-dimensional image is proposed, and it is pointed out that after the three-dimensional model is constructed in Unity 3D, the scene projection is transferred to Game panel by Camera to realize the visualization operation. Based on the appropriateness of blockchain technology and smart learning scenarios, propose a blockchain-based IoT data security collection scheme. Discuss the possible threats in the scheme, utilize the theory of reputation assessment to ensure the security of data collection, and propose the reputation assessment algorithm based on sampled data. Simulate and analyze the reputation assessment algorithm based on sampled data. Combine the survey data to analyze the propagation development of the meta-universe learning scenario. In the linear regression model, the regression coefficients of platform accompaniment, ease of use, learning immersion, resource effectiveness, platform interactivity and classroom engagement \(\beta\) are 0.467, 0.513, 0.363, 0.392, 0.336, 0.319, respectively, and all of these independent variables have a positive impact on the attitude of meta-universe learning scene use. Thus, in the subsequent development and promotion of meta-universe learning scenarios, we can focus on the convenience of scenario development and construction as well as the ease of use of the learning platform.
