In this embodiment, the rule management contract runs in a blockchain network consisting of three nodes, a, b, and c. On this basis, if a cross-link rule needs to be added: srcoaddress=achain. Addressa to white list, the steps are as follows:
1) The inter-link service related party A node invokes a rule management contract adding rule interface to apply for adding inter-link rules: srcoaddress = achain. Address a to whitelist.
2) The rule management contractor receives the application, assigns a unique identifier for the rule so as to distinguish the rule from the existing rule (effective/not effective), writes the rule into a contract change application list, and initiates the applicant (namely, the cross-chain service related party submitting the rule operation application) to count 1 ticket;
3) The cross-link service correlation Fang Yi and the propyl node detect that a rule operation application to be voted/audited exists in the contract change application list, and after checking rule meanings and completing rule evaluation, the rule management contract change voting interface is called to vote respectively (here, vote can be voted, vote can be against or directly abandoned, and the embodiment is not limited).
4) The rule management contractor receives the voting result, checks the validity of the vote, counts the vote, checks whether the number of votes in the rule operation application reaches a preset threshold (the preset threshold may be 2 in this example), reaches the preset threshold, adds srcadress=achain.
The rule modification process is similar to the rule addition process, but only unique identifiers are not required to be allocated to the rules, and the original rules are replaced/removed after the voting is passed, and the specific process is not repeated here.
