[0034] Embodiment 1

[0035] In an embodiment of the present invention, an electronic bill blockchain networking method is provided to open up data flow channels between different blockchains, and to open up data transmission channels and data mutual recognition standards that are mutually recognized by both parties.

[0036] like Figure 1 As shown, the electronic bill blockchain networking method includes the following steps S11-S12.

[0037] Step S11, constructing a corresponding bill main chain and multiple bill branch chains according to the required blockchain nodes; wherein the blockchain nodes include industry application nodes and social service nodes.

[0038] In this embodiment, the main chain is the national fiscal bill chain, for example, the Ministry of Finance bill chain. The branch chain is the local fiscal bill chain, for example, the provincial finance department bill chain. Industry application nodes include but are not limited to the Health Commission node deployed in the Health Commission, the medical insurance node deployed in the medical insurance institution, the government service node deployed in each government department and the billing node of each billing unit. Social service nodes include transmission nodes, such as cloud and social software that have the ability to undertake social services.

[0039] Among them, blockchain nodes are classified into consensus nodes and non-consensus nodes according to their uses.

[0040] Consensus nodes are used to provide the highest authority and services for consensus accounting and network-wide node management for finance. Specifically, consensus nodes include financial nodes deployed in financial departments, which are used for consensus calculation and regulatory information chain.

[0041] Non-consensus nodes are used to provide application services to invoicing units, reimbursement units, and social services; among them, application services include bill on-chain, bill query, and account feedback. Specifically, non-consensus nodes include invoicing nodes deployed in invoicing units, business nodes deployed in reimbursement units or relevant government departments, and social service nodes deployed on Internet channels. Invoicing nodes are used to perform invoicing operations including invoicing, redemption, and printing. Business nodes are used to perform bill queries, account feedback, and bill services in related businesses corresponding to the business. Social service nodes are used for bill custody, notification, bill authorization, and bill query and account feedback corresponding to social services.

[0042] Step S12, the bill main chain is connected to multiple bill branches respectively through cross-chain routing; wherein the cross-chain routing adopts the specifications and standards mutually recognized by the bill main chain and the bill branches.

[0043] For example, when the fiscal electronic invoice blockchain (main chain) shares data information with various government blockchains and other departments' self-built blockchains (branch chains), due to the differences in business and technical aspects of their respective blockchain construction standards, it is necessary to use cross-chain routing to open up mutually recognizable data transmission channels and data mutual recognition standards.

[0044] Specifically, the main chain is integrated with a first route, and each branch chain is integrated with a separate second route. The first route is connected to the second route, and the first route and the second route use the same standard encryption and decryption mechanism, which is responsible for synchronizing data and changing data formats, so that the main chain can be connected to each branch chain. Among them, the encryption and decryption mechanism of the branch chain and each branch chain may be different. The cross-chain routing service of the first route and the second route includes data transmission, data adaptation and identity authentication. Data transmission refers to the forwarding and transmission of interactive data between two chains. Data adaptation refers to the conversion of the data format of a specific chain to a unified format by the route when crossing chains. Identity authentication refers to verifying the identities of both parties during cross-chain interaction to ensure the security of the interaction.

[0045] Further, in one embodiment, if Figure 2 As shown, the step S12 in which the bill main chain is connected to the multiple bill sub-chains respectively through cross-chain routing includes the following steps S121-S125. Figure 3 This is a docking diagram for a specific case in this embodiment, that is, the main chain is the Ministry of Finance blockchain, and the branch chain is a provincial finance blockchain.

[0046] Step S121, the main chain applies to the branch chain for synchronization data through the first route.

[0047] Step S122: The second router decrypts its own branch chain data through its own encryption and decryption module and converts it into a standard format.

[0048] Step S123, the second router uses the identity of the main chain to encrypt the branch chain data in the standard format through the standard encryption and decryption mechanism and transmits it back to the first router.

[0049] Step S124, the first router decrypts the branch chain data sent by the second router through a standard encryption and decryption mechanism and converts it into a data format corresponding to the main chain.

[0050] Step S125: The first router uses the main chain identity to encrypt and upload the branch chain data that has been encrypted and converted into a data format corresponding to the main chain in the main chain.

[0052] The second aspect of the present invention provides an electronic bill blockchain networking device 100 for opening up data flow channels between different blockchains. It should be noted that the implementation principle and implementation method of the electronic bill blockchain networking device 100 are consistent with the above-mentioned electronic bill blockchain networking method, so they will not be repeated below.

[0054] The blockchain module 10 is used to construct a corresponding bill main chain and multiple bill branch chains according to the required blockchain nodes; wherein the blockchain nodes include industry application nodes and social service nodes;

[0055] The cross-chain docking module 20 is used for the bill main chain to dock with the plurality of the bill branches respectively through cross-chain routing; wherein the cross-chain routing adopts the specifications and standards mutually recognized by the bill main chain and the bill branches.

When the computer program is executed by a processor, it implements the various steps of the electronic bill blockchain networking method as described in any one of the above implementation modes.

[0060] To sum up, the electronic bill blockchain networking method, device, terminal and storage medium provided by the present invention connect the main chain with multiple branch chains through a cross-chain route. When data synchronization is required, the cross-chain route adopts the same specifications and standards to decrypt and transform the data to be synchronized, so that each blockchain can encrypt and upload the data according to its own encryption and decryption mechanism, so that the cross-chain route plays a transit role, thereby making the flow and status synchronization of bill data between different blockchains more convenient and quick.
