A multi-blockchain data processing method, device, equipment, medium and product

Abstract

The application discloses a multi-blockchain data processing method, device, equipment, medium and product. The method comprises the following steps: when a subnetwork creation request sent by a business object through a business terminal is acquired, a subnetwork creation request credential carried in the subnetwork creation request is acquired; the subnetwork creation request credential is verified through a registered business authorization credential associated with a temporary business on a target chain, and a credential verification result is obtained; when the credential verification result indicates that the verification is successful, a consensus node acquired from a first chain network is taken as a first verification node, a consensus node acquired from a second chain network is taken as a second verification node, and a business subnetwork corresponding to the temporary business is established through the first verification node and the second verification node. According to the application, the business subnetwork for executing the temporary business can be established on the basis of the multi-blockchain architecture, the waste of the main chain space is reduced, and the creation efficiency of the business subnetwork can be improved.
