Abstract: In the context of increased uncertainty in the future battlefield environment, in order to solve the problem of insufficient cross-domain collaborative incentive between combat units in the decentralized mode, a mission cooperative incentive mechanism based on the idea of token is proposed to strengthen the self-organizing ability of cross-domain collaboration among UAV combat units. Based on blockchain technology, a set of decentralized UAV cross-domain mission collaborative token ecosystem is designed, which includes two major links: one is the task release and response and the other is token issuance and circulation, the former link can be divided into four steps of task release, response, execution and evaluation, and the latter link can be divided into two steps of token issuance and circulation. Through a virtual cases of UAV unmanned cross-domain mission collaboration, in the cooperative scenes of sea, land and air forces, how to realize the whole process of cross-domain collaborative self-organization with task-oriented and "token" as reward and punishment among combat units in different fields is analyzed. The related research trends are analyzed and prospected in the end.
