With the rapid development of information technology, in higher vocational colleges and universities, the traditional way of sharing educational resources is difficult to meet the increasing demand and lacks an efficient security mechanism. In this paper, a framework of educational resource sharing system for higher vocational colleges based on blockchain and edge computing technology is proposed. Firstly, a decentralized educational resource sharing platform is constructed through the introduction of blockchain technology, which guarantees the security, transparency and non-tampering of resources. Second, combined with edge computing, it optimizes the efficiency of resource processing and transmission, reduces the delay, and improves the response speed of the system. Test results show that the “edge computing + blockchain” mode excels in upload time and data transmission efficiency, with an upload speed of 11.43 seconds, much better than the traditional data transmission mode (121 seconds). In addition, the system also demonstrates high reliability and flexibility in data storage and security. The design of the system not only meets the needs of educational resource sharing in higher vocational colleges and universities, but also provides technical support for future intelligent development in the field of education.
