Abstract

The invention discloses a blockchain cross-chain processing method and device, equipment and a storage medium, relates to the technical field of blockchains, and can be used for cloud computing and cloud services. The A specific implementation solution of the method comprises the following stepsscheme is as follows: in response to a cross-chain processing request of a source blockchain network, sending a target data query request to an organization node in a target blockchain network; obtaining a query result fed back by the organization node,; wherein the query result at least comprises an organization node signature and target data; verifying whether the acquired organization node signature satisfies a trust model of the target blockchain network; and if so, sending the target data to the source blockchain network. According to the method disclosed in the invention, the resource consumption of cross-chain processing can be reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of blockchain technology, and in particular to a blockchain cross-chain processing method, device, equipment and storage medium. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. The blockchain has the characteristics of decentralization, non-tampering, traceability, traceability, collective maintenance, openness and transparency. These characteristics ensure the "honesty" and "transparency" of the blockchain, and lay the foundation for the creation of trust in the blockchain. [0003] The data on the chain of the blockchain network is a data island, and different blockchains cannot be interconnected, which hinders the further development of the blockchain application ecology. Cross-chain technology is use...
