Description

Block chain system with annihilation mechanism
Technical Field
The invention relates to the field of data authentication, in particular to a block chain system with an annihilation mechanism.
Background
With the development of mobile communication technology, especially mobile internet and internet of things are permeating into the living field of people, and various demands for authentication services based on internet are appeared. Such as authentication of authenticity of goods, transaction information, collection information, virtual account information, virtual property, personal/enterprise identity information, credit investigation information, justice information, etc.
In the prior art, a server connected to the internet needs to be built, and then the server is accessed through an external node to inquire the information.
However, it is a difficult matter to hack the system server by means of hackers. Hackers often achieve illegal purposes by rewriting the information stored in the server. Accordingly, there is a need for an improvement in existing internet-based authentication systems.
Disclosure of Invention
The present invention is directed to solving the problems of the prior art.
The technical scheme adopted for achieving the purpose of the invention is that the block chain system with the annihilation mechanism mainly comprises K block chains. Each blockchain has a unique blockchain type sequence number. Each block chain mainly comprises m authentication centers. The block chain type sequence number mainly comprises a sequence number partition I and a sequence number partition II. Serial number partition I is an industry code and serial number partition II is a fast-moving article code or a durable article code. The authentication center is a main server. And m authentication centers have the same authority.
The commodity category of the data stored in each block chain is determined by the block chain type serial number.
Any of the central nodes reads data from the underlying database. The basic database is a server with a data storage function and performs data interaction with a block chain system with an annihilation mechanism. The basic database mainly stores bibliographic event information.
The event information is basic commodity information. The basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate, the product specification and the safe use period.
And each authentication center verifies the commodity RFID tags uploaded by the external nodes by using the basic database and feeds back verification information to the external nodes. The external node is an intelligent terminal which is connected with the multi-center authentication system and has a radio frequency identification function.
The basic database verifies the RFID tags of the commodities mainly comprises the following steps:
1) setting a block issuing period T of the multi-center authentication system with the block issuing mechanism.
2) And in the block issuing period T, the external node scans the RFID label of the commodity to be detected to obtain the digital identity authentication information of the commodity.
And the external node transmits the digital identity authentication information of the commodity to a multi-chain block chain system, and matches the digital identity authentication information with the block chain type serial number to find out a block chain P to which the RFID tag of the commodity belongs. And the block chain P generates the category information of the commodity to be detected. The category information of the to-be-detected commodities mainly comprises industry information of the commodities and fast-moving goods information/durable goods information.
3) In the block chain P, any n authentication centers are selected as block issuing nodes in a random mode. The other m-n authentication centers are non-block issuing nodes.
4) And the multi-chain block chain system transmits the digital identity authentication information of the commodity and the category information of the commodity to be tested to the block publishing node.
If the commodity to be tested is a fast-consumable product, the block data further comprises information of the past shelf life or the not past shelf life of the commodity.
The steps for judging whether the commodity has over-shelf life are mainly as follows:
a) and the multi-chain block chain system broadcasts the time for uploading the commodity digital identity authentication information by the external node to each authentication center.
b) And each authentication center finds the bibliographic event information corresponding to the digital identity authentication information of the commodity in the basic database, and reads the commodity shelf life and the commodity production date in the bibliographic event information.
Each authentication center processes the commodity shelf life, the commodity production date and the time of the external node for uploading the commodity digital identity authentication information, namely the commodity production date is subtracted from the time of the external node for uploading the commodity digital identity authentication information, and the commodity service life is obtained. And each authentication center compares and judges the service life of the commodity and the shelf life of the commodity.
And if the service life of the commodity is greater than or equal to the quality guarantee period of the commodity, the quality guarantee period of the commodity to be detected is exceeded. The authentication center broadcasts the over-shelf-life information of the commodity to the multi-chain blockchain system. The authentication center annihilates the bibliographic event information in the base database and the received block data.
When the commodity is a fast-moving commodity, after the information of the commodity which is started is broadcast as the bibliographic event authentication information in a block chain system with an annihilation mechanism, the basic database annihilates or deletes or marks the bibliographic event information of the commodity according to rules; after the information of the commodity with the past shelf life is broadcast as the bibliographic event authentication information in a block chain system of a band annihilation mechanism, the basic database annihilates or deletes or marks the bibliographic event information of the commodity according to rules.
And if the service life of the commodity is shorter than the quality guarantee period of the commodity, the commodity to be detected does not exceed the quality guarantee period. The certification center broadcasts the commodity shelf life information to the multi-chain block chain system.
c) And according to the check rule, the multi-chain block chain system judges whether the commodity has the shelf life, and transmits the digital identity authentication information of the commodity and the information of the shelf life of the commodity or the information of shelf life of the commodity which is not passed to the block publishing node.
5) And the block publishing node processes the commodity digital identity authentication information and finds the bibliographic event information corresponding to the commodity digital identity authentication information in the basic database. And the block issuing node generates block data according to the bibliographic event information in the time t.
The block data mainly comprises the bibliographic event information, the enabled information of the to-be-tested commodity and the category information of the to-be-tested commodity.
The block issuing node broadcasts the block data in the block chain P.
6) The m-n non-block publishing nodes receive the block data broadcasted.
7) And the m authentication centers respectively judge whether the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database, and broadcast the judgment result in the multi-chain block chain system. And the m authentication centers respectively store the commodity enabling information in the block data in a basic database.
8) And the multi-chain block chain system obtains a final judgment result according to a set verification rule. The check rule is a majority rule.
And if the final judgment result is that the bibliographic event information in the block data is inconsistent with the bibliographic event information in the basic database of the authentication center, returning to the step 3, and reselecting the block issuing node until the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database of the authentication center.
And if the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database of the authentication center, the multi-chain block chain system feeds the block data back to the external node. Each authentication center annihilates the received patch data.
9) And the external node acquires the basic information of the commodity to be tested.
The technical effect of the present invention is undoubted. The multi-chain block chain system constructed by the invention classifies data, and one block chain stores basic data of one type of commodities, so that the resource is saved, and the information extraction efficiency is improved. Meanwhile, the block issuing mechanism of the multi-link block chain system can ensure the correctness and the non-tamper property of the data. The invention constructs a brand-new mutual-aid system framework based on a 'people-oriented person-I-man' belt-block issuing machine system, and replaces a mining mechanism and a workload proving mechanism in a traditional block chain with a 'people-oriented person-I-man' mutual-aid mode. Therefore, a brand-new block issuing mechanism and a multi-center distributed authentication system architecture are established, and issuing functions of centers are different. The invention can be applied to a high fault-tolerant distributed computing system, and makes the mixing consistency possible. The invention has wide application value in the important fields of non-virtual currency application scenes, such as identity authentication, mastership currency issuance and the like.

The present invention is further illustrated by the following examples, but it should not be construed that the scope of the above-described subject matter is limited to the following examples. Various substitutions and alterations can be made without departing from the technical idea of the invention and the scope of the invention is covered by the present invention according to the common technical knowledge and the conventional means in the field.
Example 1:
referring to fig. 1 and 2, a blockchain system with an annihilation mechanism mainly comprises K blockchains. Each blockchain has a unique blockchain type sequence number. Each block chain mainly comprises m authentication centers. The block chain type sequence number mainly comprises a sequence number partition I and a sequence number partition II. Serial number partition I is an industry code and serial number partition II is a fast-moving article code or a durable article code. The fast-moving product code is 1, and the durable goods code is 0. The industry code is English of industry, for example, the code of communication industry is communication, the code of medical industry is iatrology, and the code of information technology industry is information technology. One industry has two block chains, one for storing the information of the fast-moving goods in the industry, and the other for storing the information of the durable goods in the industry.
As shown in fig. 1, the common user area is an external network connected into the block chain, and the external network may be a computer or a mobile terminal. The block chain is provided with m authentication centers, and each authentication center can be used as an issuing node to issue information to the whole block chain system.
The authentication center is a main server. And m authentication centers have the same authority.
Furthermore, the number of the authentication centers in each block chain can be the same or different, and the number of the authentication centers is mainly determined by the economic proportion of the industry and the category and the number of the commodities in the industry.
The commodity category of the data stored in each block chain is determined by the block chain type serial number.
For example, if the blockchain type serial number is information technology0, the corresponding blockchain stores basic information of a durable class commodity in the information technology industry.
Any of the central nodes reads data from the underlying database. The basic database is a server with a data storage function and performs data interaction with a block chain system with an annihilation mechanism. The basic database mainly stores bibliographic event information.
The event information is basic commodity information. If the commodity is a fast-consumable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate, the product specification and the safe use period, namely the quality guarantee period. If the commodity is a durable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate and the product specification.
And each authentication center verifies the commodity RFID tags uploaded by the external nodes by using the basic database and feeds back verification information to the external nodes. The external node is an intelligent terminal which is connected with the multi-center authentication system and has a radio frequency identification function.
The basic database verifies the RFID tags of the commodities mainly comprises the following steps:
1) setting a block issuing period T of the multi-center authentication system with the block issuing mechanism.
2) And in the block issuing period T, the external node scans the RFID label of the commodity to be detected to obtain the digital identity authentication information of the commodity.
And the external node transmits the digital identity authentication information of the commodity to a multi-chain block chain system, and matches the digital identity authentication information with the block chain type serial number to find out a block chain P to which the RFID tag of the commodity belongs. And the block chain P generates the category information of the commodity to be detected. The category information of the to-be-detected commodities mainly comprises industry information of the commodities and fast-moving goods information/durable goods information.
3) In the block chain P, any n authentication centers are selected as block issuing nodes in a random mode. The other m-n authentication centers are non-block issuing nodes.
4) And the multi-chain block chain system transmits the digital identity authentication information of the commodity and the category information of the commodity to be tested to the block publishing node.
If the commodity to be tested is a fast-consumable product, the block data further comprises information of the past shelf life or the not past shelf life of the commodity.
The steps for judging whether the commodity has over-shelf life are mainly as follows:
a) and the multi-chain block chain system broadcasts the time for uploading the commodity digital identity authentication information by the external node to each authentication center.
b) And each authentication center finds the bibliographic event information corresponding to the digital identity authentication information of the commodity in the basic database, and reads the commodity shelf life and the commodity production date in the bibliographic event information.
Each authentication center processes the commodity shelf life, the commodity production date and the time of the external node for uploading the commodity digital identity authentication information, namely the commodity production date is subtracted from the time of the external node for uploading the commodity digital identity authentication information, and the commodity service life is obtained. And each authentication center compares and judges the service life of the commodity and the shelf life of the commodity.
And if the service life of the commodity is greater than or equal to the quality guarantee period of the commodity, the quality guarantee period of the commodity to be detected is exceeded. The authentication center broadcasts the over-shelf-life information of the commodity to the multi-chain blockchain system. The authentication center annihilates the bibliographic event information in the database with the received tile data. When the commodity is a fast-moving commodity, after the information of the commodity which is started is broadcast as the bibliographic event authentication information in a block chain system with an annihilation mechanism, the basic database annihilates or deletes or marks the bibliographic event information of the commodity according to rules; after the information of the commodity with the past shelf life is broadcast as the bibliographic event authentication information in a block chain system of a band annihilation mechanism, the basic database annihilates or deletes or marks the bibliographic event information of the commodity according to rules.
And if the service life of the commodity is shorter than the quality guarantee period of the commodity, the quality guarantee period of the commodity to be detected is over. The certification center broadcasts the commodity shelf life information to the multi-chain block chain system.
c) And according to the check rule, the multi-chain block chain system judges whether the commodity has the shelf life, and transmits the digital identity authentication information of the commodity and the information of the shelf life of the commodity or the information of shelf life of the commodity which is not passed to the block publishing node.
5) And the block publishing node processes the commodity digital identity authentication information and finds the bibliographic event information corresponding to the commodity digital identity authentication information in the basic database. And the block issuing node generates block data according to the bibliographic event information in the time t. the time T may be a block issue period T, or may be other set time periods. The time t is mainly determined by the generation speed and the amount of the authored event authentication information.
The block data mainly comprises the bibliographic event information, the enabled information of the to-be-tested commodity and the category information of the to-be-tested commodity.
The block issuing node broadcasts the block data in the block chain P.
6) The m-n non-block publishing nodes receive the block data broadcasted.
7) And the m authentication centers respectively judge whether the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database, and broadcast the judgment result in the multi-chain block chain system. And the m authentication centers respectively store the commodity enabling information in the block data in a basic database.
8) And the multi-chain block chain system obtains a final judgment result according to a set verification rule. The check rule is a majority rule.
And if the final judgment result is that the bibliographic event information in the block data is inconsistent with the bibliographic event information in the basic database of the authentication center, returning to the step 3, and reselecting the block issuing node until the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database of the authentication center.
And if the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database of the authentication center, the multi-chain block chain system feeds the block data back to the external node. Each authentication center annihilates the patch data received by the underlying database.
9) And the external node acquires the basic information of the commodity to be tested.
The fast-moving consumer goods chain in the anti-counterfeiting authentication and the small payment chain in the financial currency comprise mass data. The life cycle of the chain of fast-moving products is defined as the longest guarantee period of the goods in the chain plus an extender, and the block chain beyond the life cycle is annihilated. The micropayment chain also sets a similar life cycle, such as a three year life cycle.
Example 2:
the implementation constructs a block chain system with an annihilation mechanism, which mainly comprises 22 block chains. Each blockchain has a unique blockchain type sequence number. The block chains 1 to 7 mainly comprise 17 authentication centers, the block chains 8 to 15 mainly comprise 9 authentication centers, and the block chains 16 to 22 mainly comprise 39 authentication centers.
The block chain type sequence number mainly comprises a sequence number partition I and a sequence number partition II. Serial number partition I is an industry code and serial number partition II is a fast-moving article code or a durable article code. The fast-moving product code is 1, and the durable goods code is 0. The industry code is English of industry, for example, the code of communication industry is communication, the code of medical industry is iatrology, and the code of information technology industry is information technology. One industry has two block chains, one for storing the information of the fast-moving goods in the industry, and the other for storing the information of the durable goods in the industry.
The authentication center is a main server. The authentication center authority in each block chain is the same. The authority of the authentication centers between different blockchains may be the same or different.
The commodity category of the data stored in each block chain is determined by the block chain type serial number.
Each authentication center has a base database. The basic database mainly stores bibliographic event information.
The event information is basic commodity information. If the commodity is a fast-consumable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate, the product specification and the safe use period, namely the quality guarantee period. If the commodity is a durable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate and the product specification.
And each authentication center verifies the commodity RFID tags uploaded by the external nodes by using the basic database and feeds back verification information to the external nodes. The external node is an intelligent terminal which is connected with the multi-center authentication system and has a radio frequency identification function.
The basic database verifies the RFID tags of the commodities mainly comprises the following steps:
1) setting a block issuing period T of the multi-center authentication system with the block issuing mechanism.
2) And in the block issuing period T, the external node scans the RFID label of the commodity to be detected to obtain the digital identity authentication information of the commodity. In this embodiment, the commodity to be tested is a flower cake.
And the external node transmits the digital identity authentication information of the commodity to a multi-chain block chain system, and matches the digital identity authentication information with the block chain type serial number to find out a block chain P to which the RFID tag of the commodity belongs. The block chain type sequence number obtained by matching is food 1. The block chain P stores basic information of fast-food products. The block chain P is an 18 th block chain and is provided with 39 authentication centers.
And the block chain P generates the category information of the commodity to be detected. The commodity category information to be detected mainly comprises that the commodity to be detected belongs to the food industry and the commodity to be detected is a fast-digestion product.
3) In the block chain P, any one authentication center is selected as a block issuing node in a random mode. The remaining 38 authentication centers are non-blocking distribution nodes.
4) And the multi-chain block chain system transmits the digital identity authentication information of the commodity and the category information of the commodity to be tested to the block publishing node.
The block data also comprises the information of the over-shelf life or the information of the non-over-shelf life of the commodity because the commodity to be detected is a fast-consumable product.
The steps for judging whether the quality guarantee period of the commodity to be detected is over are mainly as follows:
a) and the multi-chain block chain system broadcasts the time for uploading the commodity digital identity authentication information by the external node to each authentication center. In the embodiment, the time for uploading the commodity digital identity authentication information by the external node is 2019, 3, 20, 14, 30, 05, 020.
b) And each authentication center finds the bibliographic event information corresponding to the digital identity authentication information of the commodity in the basic database, and reads the commodity shelf life and the commodity production date in the bibliographic event information. The shelf life of the flower cake in this example is 45 days, and the production date is 2019, 2 months and 20 days.
Each authentication center processes the commodity shelf life, the commodity production date and the time of the external node for uploading the commodity digital identity authentication information, namely the commodity production date is subtracted from the time of the external node for uploading the commodity digital identity authentication information, and the commodity service life is obtained. And each authentication center compares and judges the service life of the commodity and the shelf life of the commodity. In this embodiment, the service life of the commodity is 30 days, and if the service life of the commodity is less than the shelf life of the commodity, the commodity to be tested does not exceed the shelf life. Each authentication center broadcasts the information of the commodity shelf life to a multi-chain block chain system, and stores the information of the commodity shelf life in the bibliographic event information of the basic database.
c) And judging whether the information of the 39 commodities with the shelf lives exceeded or not according to a check rule, namely according to a majority principle, finally judging that the commodities have the shelf lives not exceeded by the multi-chain block chain system, and transmitting the digital identity authentication information of the commodities and the information of the commodity with the shelf lives not exceeded to the block publishing node. And the block publishing node stores the information of the non-expiration date of the commodity in the corresponding bibliographic event information according to the digital identity authentication information of the commodity.
At this time, the bibliographic event information mainly includes production date, manufacturer, quality inspection qualification, product specification, safe use period, i.e. shelf life and commodity guarantee period non-passing information.
5) The block issuing node generates block data.
The block data mainly comprises the bibliographic event information, the enabled information of the to-be-tested commodity and the category information of the to-be-tested commodity.
The block issuing node broadcasts the block data in the block chain P.
6) The 38 non-block distribution nodes receive the block data that is broadcast.
7) And the 39 authentication centers respectively judge whether the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database, and broadcast the judgment result in the multi-chain block chain system. And the 39 authentication centers respectively store the commodity enabling information in the block data in a basic database.
8) And the multi-chain block chain system obtains a final judgment result according to a set verification rule. The check rule is a majority rule. And the 33 authentication centers judge that the bibliographic event information in the block data is consistent with the bibliographic event information in the authentication center basic database, the 6 authentication centers judge that the bibliographic event information in the block data is inconsistent with the bibliographic event information in the authentication center basic database, so that the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the authentication center basic database, and the multi-chain block chain system feeds the block data back to the external node.
9) And the external node acquires the basic information of the commodity to be tested.
Example 3:
the implementation constructs a block chain system with an annihilation mechanism, which mainly comprises 22 block chains. Each blockchain has a unique blockchain type sequence number. The block chains 1 to 7 mainly comprise 17 authentication centers, the block chains 8 to 15 mainly comprise 9 authentication centers, and the block chains 16 to 22 mainly comprise 39 authentication centers.
The block chain type sequence number mainly comprises a sequence number partition I and a sequence number partition II. Serial number partition I is an industry code and serial number partition II is a fast-moving article code or a durable article code. The fast-moving product code is 1, and the durable goods code is 0. The industry code is English of industry, for example, the code of communication industry is communication, the code of medical industry is iatrology, and the code of information technology industry is information technology. One industry has two block chains, one for storing the information of the fast-moving goods in the industry, and the other for storing the information of the durable goods in the industry.
The authentication center is a main server. The authentication center authority in each block chain is the same. The authority of the authentication centers between different blockchains may be the same or different.
The commodity category of the data stored in each block chain is determined by the block chain type serial number.
Each authentication center has a base database. The basic database mainly stores bibliographic event information.
The event information is basic commodity information. If the commodity is a fast-consumable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate, the product specification and the safe use period, namely the quality guarantee period. If the commodity is a durable product, the basic information of the commodity mainly comprises the production date, the manufacturer, the quality inspection qualification certificate and the product specification.
And each authentication center verifies the commodity RFID tags uploaded by the external nodes by using the basic database and feeds back verification information to the external nodes. The external node is an intelligent terminal which is connected with the multi-center authentication system and has a radio frequency identification function.
The basic database verifies the RFID tags of the commodities mainly comprises the following steps:
1) setting a block issuing period T of the multi-center authentication system with the block issuing mechanism.
2) And in the block issuing period T, the external node scans the RFID label of the commodity to be detected to obtain the digital identity authentication information of the commodity. In this embodiment, the commodity to be tested is a flower cake.
And the external node transmits the digital identity authentication information of the commodity to a multi-chain block chain system, and matches the digital identity authentication information with the block chain type serial number to find out a block chain P to which the RFID tag of the commodity belongs. The block chain type sequence number obtained by matching is food 1. The block chain P stores basic information of fast-food products. The block chain P is an 18 th block chain and is provided with 39 authentication centers.
And the block chain P generates the category information of the commodity to be detected. The commodity category information to be detected mainly comprises that the commodity to be detected belongs to the food industry and the commodity to be detected is a fast-digestion product.
3) In the block chain P, any one authentication center is selected as a block issuing node in a random mode. The remaining 38 authentication centers are non-blocking distribution nodes.
4) And the multi-chain block chain system transmits the digital identity authentication information of the commodity and the category information of the commodity to be tested to the block publishing node.
The block data also comprises the information of the over-shelf life or the information of the non-over-shelf life of the commodity because the commodity to be detected is a fast-consumable product.
The steps for judging whether the quality guarantee period of the commodity to be detected is over are mainly as follows:
a) and the multi-chain block chain system broadcasts the time for uploading the commodity digital identity authentication information by the external node to each authentication center. In the embodiment, the time for uploading the commodity digital identity authentication information by the external node is 2019, 3, 20, 14, 30, 05, 020.
b) And each authentication center finds the bibliographic event information corresponding to the digital identity authentication information of the commodity in the basic database, and reads the commodity shelf life and the commodity production date in the bibliographic event information. The shelf life of the flower cake in this example was 45 days, and the production date was 2019, 1 month and 15 days.
Each authentication center processes the commodity shelf life, the commodity production date and the time of the external node for uploading the commodity digital identity authentication information, namely the commodity production date is subtracted from the time of the external node for uploading the commodity digital identity authentication information, and the commodity service life is obtained. And each authentication center compares and judges the service life of the commodity and the shelf life of the commodity. In this embodiment, the life of the commodity is 65 days, and if the life of the commodity is longer than the shelf life of the commodity, the shelf life of the commodity to be tested is over. Each authentication center broadcasts the information of the commodity shelf life which is not over to the multi-chain block chain system, and stores the information of the commodity shelf life which is over to the bibliographic event information of the basic database.
c) And judging whether the information of the 39 commodities with the shelf lives exceeded or not according to a check rule, namely according to a majority principle, finally judging that the commodities have the shelf lives not exceeded by the multi-chain block chain system, and transmitting the digital identity authentication information of the commodities and the information of the commodity with the shelf lives not exceeded to the block publishing node. And the block publishing node stores the commodity shelf life information in the corresponding bibliographic event information according to the commodity digital identity authentication information. Because the commodity has passed the shelf life, the information of storing this commodity has had no meaning, in order to save resources as far as possible, every authentication center annihilates the event information of the matter of writing that this commodity corresponds.
At this time, the bibliographic event information mainly includes production date, manufacturer, quality inspection qualification, product specification, safe use period, i.e. shelf life and commodity guarantee period information.
5) The block issuing node generates block data.
The block data mainly comprises the bibliographic event information, the enabled information of the to-be-tested commodity and the category information of the to-be-tested commodity.
The block issuing node broadcasts the block data in the block chain P.
6) The 38 non-block distribution nodes receive the block data that is broadcast.
7) And the 39 authentication centers respectively judge whether the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database, and broadcast the judgment result in the multi-chain block chain system. And the 39 authentication centers respectively store the commodity enabling information in the block data in a basic database.
8) And the multi-chain block chain system obtains a final judgment result according to a set verification rule. The check rule is a majority rule. And the 33 authentication centers judge that the bibliographic event information in the block data is consistent with the bibliographic event information in the authentication center basic database, and the 6 authentication centers judge that the bibliographic event information in the block data is inconsistent with the bibliographic event information in the authentication center basic database, so that the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the authentication center basic database.
And if the final judgment result is that the bibliographic event information in the block data is consistent with the bibliographic event information in the basic database of the authentication center, the multi-chain block chain system feeds the block data back to the external node.
9) And the external node acquires the basic information of the commodity to be tested.
