S103: and receiving voting results of other legal service chains submitted to the target access application, and judging whether to add the target service chain into the cross-chain network according to the voting results of other legal service chains to the target access application.
In this embodiment, the relay chain waits for all legal members (i.e. other legal service chains) to call the "voting interface" of the real-name system contract to perform voting confirmation by using their real-name system addresses, and determines whether to add the target service chain into the cross-chain network according to the voting result of the other legal service chains on the target access application.

and adding the target access application which is checked successfully into a preset service chain application list.
In this embodiment, before the target access application is added to the preset service chain application list, the target access application may be checked, and only the target access application that is checked successfully is added to the preset service chain application list. And if the verification of the target access application fails, returning information of the failure of the verification of the access application to the target service chain.
Optionally, referring to fig. 4, as a specific implementation manner of the service link access management method based on the blockchain intelligent contract provided by the embodiment of the present invention, the target access application includes a chain name of the target service link, a chain type of the target service link, and a real-name system address of the target service link.

checking whether the ChainType is legal, whether the ChainName is in the joined cross-link service chain list, whether the MyAddress of the target service chain is in the confirmed member list, and whether the MyAddress of the target service chain is the effective transfer-out address of the call transaction. If the ChainType is legal, the ChainName is not in the list of the added cross-link service chains, the MyAddress of the target service chain is not in the list of the confirmed members, and the MyAddress of the target service chain is the effective transfer address of the call transaction, the target access application verification is judged to be successful.
The confirmed member list comprises the chain names of all legal service chains which are added into the cross-chain network, and the confirmed member list comprises real-name system addresses of all legal service chains which are added into the cross-chain network.

If the verification fails, the voting failure information is returned to the corresponding legal service chain.
Optionally, referring to fig. 5, as a specific implementation manner of the service link access management method based on the blockchain intelligent contract provided by the embodiment of the present invention, the voting result submitted by other legal service links for the target access application includes the link name of the target service link, the link type of the target service link, the voting result of other legal service links, the real-name system address of other legal service links, the common address provided by other legal service links for generating the multi-signature address of the target service link, and the public key corresponding to the common address provided by other legal service links.

In this embodiment, both the sub address and the sub address are used to generate the multi-signature address of the target service chain.
In this embodiment, the current call transaction refers to the process that the legal service chain calls the "voting interface" of the real-name system contract with its own real-name system address.
In this embodiment, the purpose of verifying whether the MyAddress of the legal service chain is an effective address of the call transaction is to ensure that the contract caller is consistent with the MyAddress identity, and prevent malicious impersonation voting.
In this embodiment, as shown in fig. 5, after verification is successful, if it is determined that the target service chain is to be added to the cross-link network according to voting results of other legal service chains that are successful in verification, then a multi-signature address corresponding to the target service chain may be generated according to the SubAddress and the subpublic carried in the voting results, the target service chain is added to the added cross-link service chain list ConfirmedChains of the real-name system contract, the multi-signature address corresponding to the target service chain is written into the confirmed member list confirmedpots of the real-name system contract, and the target access application entry in the service chain application list NodeAplicationList is deleted.
From the above description, the invention manages the members and contracts of the chain by using a real-name system, the transaction process is traceable and can not be changed, and the disclosure is transparent. By combining the information of different service chains, the invention can realize complete and comprehensive cross-chain network service, realize information value transfer among different chains and is beneficial to establishing a harmonious and safe cross-chain ecological environment.

if the voting results of other legal service chains on the target access application show that the number of other legal service chains which approve the addition of the target service chain exceeds the preset proportion of the total number of legal service chains in the cross-chain network, adding the target service chain into the cross-chain network, generating a multi-signature address corresponding to the target service chain according to the voting results of other legal service chains on the target access application, and sending information of successful addition to the target service chain. Wherein the multi-signature address is used in a cross-chain transaction across a chain network.
If the voting result of other legal service chains on the target access application shows that the number of other legal service chains which approve the joining of the target service chain does not exceed the preset proportion of the total number of legal service chains in the cross-chain network, the target service chain is not joined into the cross-chain network, and the joining failure information is sent to the target service chain.
The preset proportion can be set according to actual requirements, and is not limited herein.
In this embodiment, the target service chain is added to the cross-chain network, that is, the target service chain is added to the list of the added cross-chain service chains, and meanwhile, the embodiment also generates and stores a multi-signature address corresponding to the target service chain according to the voting results of other legal service chains on the target access application, so that the target service chain can perform subsequent cross-chain transactions.
