Abstract: The lack of effective connection of physical education curriculum in primary schools, secondary schools and colleges is a prominent problem that restricts the development of school physical education. As the core of information-based teaching, blockchain provides technical possiblities for the integration of physical education curriculum. By using the methods of literature review and the ASMI four steps, the application scenario selection, framework design and implementation path of blockchain technology are studied in the construction of physical education curriculum integration. It is held that blockchain can not only solve the problems involving vertical fault, horizontal development imbalance, internal disunity, and form disconnection in school physical education, but provide new combination regulation and functional effectiveness for curriculum structure elements by "technology empowerment", which will fundamentally change the education organization modes and teaching patterns. Combined with the general structure of blockchain and the integrated application scenario of physical education curriculum, the multi-chain composite system framework including technical support system (infrastructure and network), consensus layer, intelligent contract layer, data layer, application layer and other modules is constructed, and the consensus, storage, transmission and security mechanism of the system operation are analyzed. On this basis, the development countermeasures are put forward from the policy orientation, technology research and development and personnel training, large-scale development, etc.
