Example one
In the embodiment of the invention, the electronic bill block chain networking method is provided, which is used for opening a data circulation channel between different block chains, and opening a data transmission channel and a data mutual authentication standard which can be mutually authenticated by the two parties.
As shown in fig. 1, the electronic ticket blockchain networking method includes the following steps S11-S12.
Step S11, constructing a corresponding bill main chain and a plurality of bill branched chains according to the required block chain link points; the block link nodes comprise industry application nodes and social service nodes.
In this embodiment, the main chain is a national financial bill chain, for example, the finance department bill chain. The branch chain is a local financial bill chain, such as a bill chain of each provincial and political hall. The industry application nodes include, but are not limited to, health care committee nodes deployed in health care committee, medical insurance nodes deployed in medical insurance institutions, government affair service nodes deployed in each government department, and invoicing nodes of each invoicing unit. The social service node comprises a transmission node, such as a cloud terminal with the capability of undertaking social services, social software and the like.
The block chain nodes are classified according to purposes and comprise common nodes and non-common nodes.
The consensus node is used for providing the highest authority and service for the consensus accounting and the whole network node management facing the finance. Specifically, the consensus node comprises a financial node deployed in a financial department, and the financial node is used for consensus computing and supervision information chaining.
The non-consensus node is used for providing application services for billing units, reimbursement units and social services; the application service comprises a bill chaining, a bill inquiry and an account entry feedback. Specifically, the non-consensus nodes include billing nodes deployed in billing units, business nodes deployed in reimbursement units or related government departments, and social service nodes deployed in internet channels. And the billing node is used for performing billing operation including billing, flushing and printing. The service node is used for carrying out bill query and account feedback corresponding to the service and bill service in the related service. The social service node is used for bill keeping, notification, bill authorization, and bill inquiry and posting feedback corresponding to the social service.
Step S12, the main chain of the bill is respectively butted with a plurality of bill branched chains through a cross-link; the cross-link adopts the specification and standard that the main chain and the branch chain of the bill are mutually recognized.
For example, when a financial electronic bill block chain (main chain) shares data information with various government affair block chains and self-built block chains (branch chains) of other departments, due to differences of respective block chain building standards in business and technical aspects, a data transmission channel and a data mutual-recognition standard which can be mutually recognized by both parties need to be communicated in a cross-link routing mode.
Specifically, the main chain is provided with a first route in an integrated mode, and each branched chain is provided with a separate second route in an integrated mode. The first route and the second route are in butt joint, the same standard encryption and decryption mechanism is adopted by the first route and the second route, and the first route and the second route are responsible for synchronizing data and replacing data formats, so that the main chain can be in butt joint with each branched chain. Wherein, the encryption and decryption mechanism of the branched chain and each branched chain can be different. In the cross-link routing service of the first route and the second route, data transmission, data adaptation and identity verification are included. Data transmission refers to forwarding and transmitting interactive data between two chains. Data adaptation refers to the way a particular chain's data format is inter-converted to a uniform format across the chain. The identity authentication refers to the authentication of the identities of the two parties during cross-chain interaction, so that the interaction safety is ensured.
Further, in one embodiment, as shown in fig. 2, the step S12 of interfacing the bill main chain with the plurality of bill branch chains through the cross link includes the following steps S121 to S125. Fig. 3 is a schematic diagram of the embodiment as a specific example of the docking, that is, the main chain is a fiscal department block chain, and the branch chain is a certain provincial fiscal block chain.
And step S121, the main chain applies for synchronous data to the branched chain through a first route.
And step S122, the second route decrypts the branched-chain data of the second route through the encryption and decryption module of the second route and converts the branched-chain data into a standard format.
And step S123, the second route encrypts the branched chain data in the standard format by using the identity of the main chain through a standard encryption and decryption mechanism and returns the branched chain data to the first route.
Step S124, the first route decrypts the branched-chain data sent by the second route through a standard encryption and decryption mechanism and converts the branched-chain data into a data format corresponding to the main chain.
In step S125, the first router encrypts the branch data, which is encrypted by the main chain identity and has been converted into the data format corresponding to the main chain, in the main chain for uplink encryption.
