Cross-chain interaction using domain name scheme in blockchain system

摘要

The implementation of the present invention comprises the steps of: identifying a blockchain domain name of the first blockchain instance by a relay communicatively linked to the first blockchain instance and the second blockchain instance of the integrated blockchain network; Identifying a blockchain domain name of the second blockchain instance; Receiving an access request to access the second blockchain instance from a node of the first blockchain instance, the access request comprising the blockchain domain name of the second blockchain instance; Identifying a chain identifier of the second blockchain instance based on the blockchain domain name of the second blockchain instance, wherein the chain identifier of the second blockchain instance represents the blockchain network configuration of the second blockchain instance ; And providing access to the second blockchain instance for the first blockchain instance based on the blockchain network configuration indicated by the chain identifier of the second blockchain instance.
