Abstract

The invention discloses a cross-chain processing method, device and system between heterogeneous chains, electronic equipment and a storage medium, and relates to the field of data processing, in particular to the technical field of block chains. The method specifically comprises: in response to received demand information, generating a corresponding out-of-chain service query request according to the demand information; sending the out-of-chain service query request to a relay chain; receiving target out-of-chain service information fed back by the relay chain, and obtaining an access token for the target out-of-chain service information fed back by the relay chain, wherein the access token comprises service address information and service provider signature information; and receiving the access token fed back by the relay chain, and sending a transaction request to a corresponding target application chain according to service address information in the access token, wherein the transaction request is used for indicating the target application chain to execute the transaction operation when the transaction is verified to be legal according to the service provider signature information in the access token.

Description

technical field [0001] The present application relates to the technical field of blockchain in the technical field of data processing, and in particular to a cross-chain processing method, device, system, electronic equipment and storage medium between heterogeneous chains. Background technique [0002] Cross-chain technology can solve the problem of mutual calling between blockchains, and can realize data sharing between different blockchain systems. In related technologies, the authorization and traceability of transactions cannot be realized. In some cases, even if cross-system transactions are completed, secure networking with the original system cannot be realized. Contents of the invention [0003] The present application provides a method, device, system, electronic device and storage medium for cross-chain processing between heterogeneous chains. [0004] According to the first aspect of the present application, a cross-chain processing method between heterogeneou...
