Calling method and device between federated clusters, block chain system and storage medium

The invention provides an inter-federated cluster calling method and device, a block chain system and a storage medium, and relates to the technical field of computers. The method comprises the following steps: receiving a resource calling request sent by a request cluster through a corresponding block chain node by a supervision node in a block chain system, obtaining a feasibility judgment result of executing a target resource calling operation by a target cluster through a main cluster in a plurality of federated clusters, and executing the resource calling operation by the target cluster under the condition that the feasibility judgment result indicates that the resource calling operation is feasible; and generating an authorization certificate through the smart contract, and sending the authorization certificate to the request cluster through the block chain node corresponding to the request cluster, so that the request cluster enables the target cluster to execute a target resource calling operation bas
