Cross-chain collaborative governance system, method and device and storage medium

A cross-chain collaborative governance method, applied to a cross-chain collaborative governance system, comprising:

• providing a first application subchain and a second application subchain with access to the cross-chain collaborative governance system;
• the first application subchain being arranged in a first blockchain network and the second application subchain being arranged in a second blockchain network in a cross-chain alliance;
• constructing a first governance node associated with the first application subchain and a second governance node associated with the second application subchain in a governance chain, the governance chain comprising a blockchain distinct from the first blockchain network and the second blockchain network, the first governance node corresponding to a management organization of the first application subchain, the second governance node corresponding to a management organization of the second application subchain, the management organizations of the first application subchain and the second application subchain jointly participating in the control governance on the cross-chain interoperation through the governance chain;
• deploying a first collaborative service program in the first blockchain network and a second collaborative service program in the second blockchain network;
• establishing communication connection between the first collaborative service program and the second collaborative service program, and performing cross-chain interoperation between the first application subchain and the second application subchain;
• establishing communication connection between the first collaborative service program and the first governance node and communication connection between the second collaborative service program and the second governance node;
• and
• performing control governance on the cross-chain interoperation between the first application subchain and the second application subchain.

A non-transitory computer-readable storage medium, comprising a computer program, the computer program, when loaded and executed by a processor, causing the processor to perform:

• providing a first application subchain and a second application subchain with access to the cross-chain collaborative governance system;
• the first application subchain being arranged in a first blockchain network and the second application subchain being arranged in a second blockchain network in a cross-chain alliance;
• constructing a first governance node associated with the first application subchain and a second governance node associated with the second application subchain in a governance chain, the governance chain comprising a blockchain distinct from the first blockchain network and the second blockchain network, the first governance node corresponding to a management organization of the first application subchain, the second governance node corresponding to a management organization of the second application subchain, the management organizations of the first application subchain and the second application subchain jointly participating in the control governance on the cross-chain interoperation through the governance chain;
• deploying a first collaborative service program in the first blockchain network and a second collaborative service program in the second blockchain network;
• establishing communication connection between the first collaborative service program and the second collaborative service program, and performing cross-chain interoperation between the first application subchain and the second application subchain;
• establishing communication connection between the first collaborative service program and the first governance node and communication connection between the second collaborative service program and the second governance node;
• and
• performing control governance on the cross-chain interoperation between the first application subchain and the second application subchain.
