The resource database of traditional civil aviation safety technology teaching resources is not comprehensive,and the sharing effect is not good.Based on this,the teaching resource sharing method of civil aviation security technology based on blockchain technology is proposed,which builds a model from the application layer,contract layer and data layer,clarifies the transmission efficiency and channel of the resources,and realizes the sharing of teaching resources.The experimental results show that compared with the traditional method,this method has higher resource utilization rate and better sharing effect.
