The service chain C also has a cross-chain requirement and wants to join the network, and needs to initiate an application first, and members in the network vote and confirm to join after passing. The specific operation process is as follows:
the relay link node needs to issue a real-name contract first, the service link C submits information for applying for joining, members of the service link A and the service link B call the real-name contract to vote, bidirectional real-name verification (the real-name contract verifies the identity of a caller, and the real-name caller verifies the authenticity of the contract) is performed during voting, the number of votes obtained by the service link C is counted by the relay link Z after the vote is verified, if the service link C obtains the number of votes with a preset proportion (for example, more than 60 percent) the service link C agrees to join the service link C, a multi-signature address corresponding to the service link C is generated according to common addresses and public key information of other legal members carried in the voting result, the service link C and the multi-signature address corresponding to the service link C are written into the contract state of the real-name contract, and the service link C is formally joined into the cross-link network.
