Parking space sharing method based on alliance chain mechanism

The invention relates to a parking space sharing method based on an alliance chain mechanism. Compared with the prior art, the problems that a wide trust basis among participants cannot be established, the resource consumption is large, the consensus time delay is long and the like are solved. The method comprises the following steps of system initialization, a reservation request of parking space sharing, parking space sharing transaction and credit evaluation, and generation of a block by the alliance user and block chaining. A chain structure of an alliance chain is designed to establish a wide trust basis of each participant, so that the actual applicability of the parking space sharing method is higher; a consensus mechanism based on the combination of a simplified Byzantine algorithm and a POS is adopted to reduce resource consumption and realize rapid consensus, and therefore, the sharing optimization of the parking space is finally realized. 本发明涉及一种基于联盟链机制的停车位共享方法，与现有技术相比解决了无法建立广泛的各参与方之间的信任基础、资源消耗大、共识
