Blockchain-Based Design of a Multi-Domain Joint Combat Simulation System

With the concept of multi-domain joint combat, the future joint combat simulation system will develop in the direction of trans-military species and trans-regional. In response to the problem that the existing combat simulation system can hardly guarantee the security and reliability of data interaction in multi-domain joint combat simulation, a blockchain-based multi-domain joint combat simulation system framework is constructed. The corresponding technical solutions are given for the data layer, network layer, consensus layer, contract layer and application layer of the system. The block storage format of the data layer, the content of the simulation data to be packaged and the verification method during transmission are mainly studied. Proposed a hybrid consensus mechanism based on traditional deterministic consensus algorithm with high availability and high fault tolerance. A smart contract for the joint combat simulation process and a smart contract for the secondary processing of simulation data are designed. Finally, the workflow of the whole system is illustrated by a case study.
