Based on the cloud platform, the concept and importance of double-precision teaching in wisdom teaching is analyzed, and the basic framework of online and offline wisdom teaching based on blockchain technology is constructed in this paper. Based on the characteristics of blockchain such as security and decentralization, an accurate learning resource teaching model based on knowledge representation of learners and teaching resources is proposed. A double-precision collaborative strategy of accurate perception of wisdom teaching demand and accurate supply of resources is proposed. The framework of wisdom teaching is constructed, in which the accurate perception of wisdom teaching demand and the accurate supply of resources based on big data technology is analyzed. Based on blockchain technology, tracking the learning records of learners at each stage of learning is helpful. It effectively promotes the distribution and sharing of learning resources, efficiently bridges teaching resources and learning requirements, and provides more accurate, personalized learning support, and services for learners. It provides a secure data access strategy for both teachers and learners. The precise wisdom teaching framework based on blockchain technology has far-reaching practical value for the efficient development of online and offline teaching.
