Cross-chain caching strategy generation method and related equipment

The invention provides a cross-chain caching strategy generation method and related equipment, the cross-chain caching strategy generation method is applied to a multi-chain Internet of Things system, the cross-chain caching strategy generation method comprises a block chain network module, an edge node module and an Internet of Things equipment module, the Internet of Things equipment module is connected with the block chain network module through the edge node module, and a plurality of initial caching strategies of edge nodes are obtained; updating each initial cache strategy based on the individual extreme value and the global extreme value to obtain a corresponding updated cache strategy; determining an initial capability value of each cache updating strategy by using a simulated annealing-binary particle swarm algorithm; when it is determined that the initial capability values are all smaller than a preset threshold value, performing optimization processing on each initial capability value by using simu
