Detailed ways

In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

Detailed descriptions are given below.

The following first describes the system architecture of this solution. Refer to FIG. 1, which is a schematic diagram of the system architecture of a blockchain-based list type query method provided by an embodiment of the solution. As shown in FIG. 1, the system architecture may include one or more blockchains 102 and one or more blockchain nodes 101. The blockchain 102 and the blockchain node 101 together form a regional cross-chain platform system. Among them, the block chain 102 is used to store data, and each time the block chain node 101 completes a transaction, the corresponding data will be put into the chain, that is, added to the block chain 102 for storage backup. Blockchain node 101 refers to the computers in the blockchain platform system, including mobile phones, mining machines, desktops, servers, and so on. The people who operate a blockchain node can be ordinary wallet users, miners and multiple people. For example, the Bitcoin network is a public chain. When we run the bitcoind program on our computer connected to the Internet, the computer becomes a blockchain node in the Bitcoin network. The blockchain node of the blockchain has the following characteristics: it has a certain storage space, can connect to the network, and belongs to the current mainstream visual operation terminals such as mobile phones, tablets, and desktop computers. Participating in the blockchain is to connect to the storage space of the network. Run the corresponding program of the blockchain and conduct transactions through the visual operation terminal. It should be noted that the system architecture to which the embodiments of the present application can be applied is not limited to the architecture described in FIG. 1.

Based on the system architecture of a blockchain-based list type query method provided by the embodiment of the solution shown in Figure 1, the following provides a blockchain-based list type query method. The flowchart of the list type query method is shown in the figure 2 shown. The method can include the following steps:

Step S101: The first blockchain node sends a query request to other blockchain nodes in the blockchain platform system through a broadcast mechanism, and the query request carries a list of the type of list that needs to be queried.

Specifically, the list types include blacklist, whitelist, and graylist. The blacklist may include one or more of a credit blacklist, an industry blacklist, an institution blacklist, a fraud blacklist, and a court blacklist. If there are more than one, the classified storage is convenient for query; the graylist It can include one or more of online loan applications that are not creditworthy, habitually overdue, borrowing from multiple institutions, finding multiple intermediaries, excessive comprehensive debt, tendency to fraudulent loans, and history of high borrowing Similarly, if there are multiple behavior lists, they are classified and stored for easy query; the white list is a list other than the black list and the gray list.

In a specific embodiment, the first block chain node and the other block chain nodes mentioned above are all block chain nodes in the same block chain platform system. The first blockchain node needs to query the type of the list in the blockchain platform system, that is, it needs to initiate a transaction. The transaction is the first blockchain node requesting other blockchain nodes in the blockchain platform system to query a certain For the specific list type, if the query is successful, the blockchain node that is successfully queried can obtain a reward, which can be the right to use a certain operation. Specifically, the first blockchain node broadcasts a list type query request to nearby blockchain nodes, that is, sends request information that needs to query the list type, and the request information carries list information that needs to be queried, and the list information can be Include one or more lists to be queried. After receiving the request information, the nearby blockchain nodes send the request information to their respective nearby blockchain nodes. This will continue to spread and spread, and soon all the blockchain nodes of the entire blockchain platform system will receive it. The request information is reached. For details, please refer to Figure 3. Figure 3 shows only part of the blockchain nodes in the blockchain platform system. Node 1 is a node in the blockchain platform system. There are many nearby nodes, which are similar to node 1. The nodes that can communicate directly include node 2, node 3, node 4, node 6, and node 8. When node 1 needs to initiate a list type confirmation transaction, it will send to node 2, node 3, node 4, node 6 and node 8. The request information is sent by broadcast, and after receiving the request information, node 2, node 3, node 4, node 6 and node 8 send the request information to the nodes that have established communication with them. In this way, the nodes that receive the request information continue to The node that established the communication broadcasted the request information, and soon all nodes of the entire blockchain platform system received the request information.

Step S102: In the case that there are multiple lists of the list type that need to be queried, the first blockchain node receives information sent by the second blockchain node confirming that the first list is the first type list.

Specifically, the first type is any one of multiple list types existing on the second blockchain node, the first list is any one of the multiple lists, and the first The second blockchain node is any one of the other blockchain nodes, and the multiple list types may include at least two of blacklist, whitelist, and graylist.

In a specific embodiment, when the list information carried in the request information includes multiple lists that need to be queried, the blockchain node that receives the request information publishes the multiple lists that need to be queried one by one with itself in the blockchain platform system The list database is compared and matched; if a block chain node happens to match the multiple lists that need to be queried, it can be learned separately according to which type of list the matched list is stored in the database The types of the multiple lists that need to be queried. In the multiple lists that need to be queried, different lists may have different list types; then, the successfully matched blockchain node sends the list type information of the multiple lists to The first blockchain node, further, the successfully matched blockchain node may also send detailed information of the multiple lists stored in the database to the first blockchain node.

Or, when the list information carried in the request information includes multiple lists that need to be queried, the blockchain node that receives the request information will compare the multiple lists that need to be queried with the list database published by itself in the blockchain platform system one by one. Contrast matching; if a block chain node happens to match the partial list of multiple lists that need to be queried successfully, then according to which type of list the successfully matched list is stored in the database, you can know the Part of the list of the list type, and another blockchain node successfully matches the other part of the list, then the list of the other part of the list can be obtained according to which type of list the successfully matched list is stored in the database Type; then, the certain blockchain node sends the list type of the partial list to the first blockchain node, and further, the certain blockchain node can also send the detailed information of the partial list stored in the database Sent to the first blockchain node; on the other hand, the other blockchain node sends the list type of the other part of the list to the first blockchain node, and further, the certain blockchain node can also send The detailed information of the other part of the list stored in the database is sent to the first blockchain node.

Or, if one of the above-mentioned blockchain nodes inquires that a certain list is a certain type of list, and the above-mentioned another blockchain node also compares and matches the certain list, but the result of the comparison and matching is that certain list It is another type of list, that is, the list type of the list obtained by comparison and matching between two blockchain nodes on the same list is different, then both blockchain nodes can feed back the results of their comparison and matching to the first area Block chain node.

There are other possible implementations. For example, if the list information carried in the request information contains multiple lists that need to be queried, then two or more blockchain nodes in the blockchain platform system can jointly complete the query. The specific query process of each blockchain node can refer to the above description, which will not be repeated here.

For ease of understanding, an example is used for illustration. See Table 1 for details. The list database in Table 1 contains list data of three types of lists, the three types of lists are blacklist, greylist and whitelist. Each list type stores multiple corresponding types of enterprise information, which includes the name of the enterprise, the province where the enterprise is located, and the legal representative of the enterprise. In fact, it can also include more enterprise information such as the enterprise’s unified social credit code. And so on, if it is a blacklisted company list database, it can also include the specific content and other information that the company has done in violation of regulations and laws.

Table 1 List Database 1

Assuming that the list database shown in Table 1 is a database published by a certain blockchain node on the blockchain platform system, the first blockchain node needs to query the list of the list type as the third company and the tenth company. Then the first blockchain node sends the query request information carrying the list of the third company and the list of the tenth company to other blockchain nodes in the blockchain platform system through the broadcast mechanism. When the certain blockchain node receives When requesting information, obtain the third company list and the tenth company list in the requested information, compare and match the two lists with the lists in the list database, and finally match the third company in the blacklist type, and in the whitelist type If it matches the tenth company, the third company is blacklisted and the tenth company is whitelisted. This blockchain node will query the information of the third company as blacklisted and the tenth company. The information of the whitelist type is sent to the first blockchain node. At the same time, the provinces where the third company and the tenth company are located and their legal representatives can also be sent to the first blockchain node.

Table 2 List database 2

For another example, see Table 1 and Table 2. Suppose that the list database shown in Table 1 is a database published by a blockchain node on the blockchain platform system, and the list database shown in Table 2 is a database published by another blockchain node on the blockchain platform system ; The first block chain node needs to query the list of types for the third company and the nineteenth company. Then the first blockchain node sends the query request information carrying the list of the third company and the list of the nineteenth company to other blockchain nodes in the blockchain platform system through the broadcast mechanism. When the certain blockchain node receives When it comes to the requested information, obtain the third company list and the nineteenth company list in the requested information, compare and match the two lists with the lists in the list database, and finally match the third company in the blacklist type, that is, query The third company is a blacklist type, but the nineteenth company cannot be matched in the database, then the certain blockchain node only sends the information that the third company has been queried as the blacklist type to the first blockchain node At the same time, the province and legal representative of the third company can also be sent to the first blockchain node. On the other hand, another blockchain node that received the requested information obtains the list of the third company and the list of the nineteenth company in the requested information, compares and matches the two lists with the list in the list database, and finally in gray The nineteenth company is matched in the list type, that is, the nineteenth company is queried as a graylist type, but the third company cannot be matched in the database, then the other blockchain node will only queried the nineteenth company as The graylist type information is sent to the first blockchain node, and the province where the nineteenth company is located and its legal representative can also be sent to the first blockchain node. In this way, the two blockchain nodes jointly complete the query of the list type carrying the list in the request information.

In one of the examples, if in the above-mentioned other aspect, another blockchain node that received the requested information finally matches the nineteenth company in the graylist type, that is, the nineteenth company is queried as the graylist type , And the third company is matched in the graylist type in the database, that is, the query third company is a graylist type, then the other blockchain node can graylist the queried third company and the nineteenth company The type of information is sent to the first blockchain node. At the same time, the province where the third company and the nineteenth company are located and their legal representatives can also be sent to the first blockchain node. In this way, the two blockchain nodes jointly complete the query of the list type carrying the list in the request information.

The list of the list type that the first blockchain node needs to query may also include more than three lists. If more than three lists need to be queried, the specific description can refer to the above example description, which will not be repeated here.

Step S103: The first blockchain node allocates the first use right to the second blockchain node according to the first use right acquisition request.

Specifically, the first use right acquisition request is the first use right acquisition request sent to the first blockchain node after the second blockchain node confirms that the first list is the first type list. The first use right is any one of the multiple use rights that the second blockchain node can choose to obtain after confirming that the first list is the first type list.

In a specific embodiment, after the first blockchain node receives the list type information of the query list sent by a certain blockchain node, the certain blockchain node obtains a certain reward, and the reward method can be various. You can choose a reward equivalent to the contribution it makes. The reward can be the use right of a certain operation or the use right of a certain amount of digital currency/contribution value, etc. After the certain blockchain node selects its desired use right reward, the first blockchain node allocates its corresponding use right according to the reward method selected by the certain blockchain node.

In one of the possible implementation manners, after the first blockchain node sends a query request to other blockchain nodes in the blockchain platform system through a broadcast mechanism, it further includes: In the case where the list includes one list, the first blockchain node receives information sent by the third blockchain node confirming that the list of the list type that needs to be queried is the second type list.

Specifically, the second type is any one of the multiple list types existing on the third blockchain node, and the third blockchain node is one of the other blockchain nodes Any node; the multiple list types may include at least two of blacklist, whitelist and graylist.

In a specific embodiment, after receiving the request information sent by the first blockchain node, the blockchain node in the blockchain platform system obtains the list information carried in the request information, and the list information includes the type of list that needs to be queried The list can include one or more lists to be queried. When the list information only includes a list that needs to be queried, the blockchain node that receives the requested information compares and matches the list of the list type that needs to be queried in the list information with the list database published by itself in the blockchain platform system. The list database can be stored in the blockchain platform system according to the type of list; if a certain blockchain node is matched successfully, it can be known according to which type of list the matched list is stored in the database. The type of list to be queried. Then, the certain blockchain node feeds back the list type information of the list to the first blockchain node, and further, the certain blockchain node may also send the detailed information of the list stored in the database To the first blockchain node, specifically, the certain blockchain node can feed back information to the first blockchain node by broadcasting.

For ease of understanding, an example is used for illustration. See Table 1 for details. Assuming that the list database shown in Table 1 is a database published by a certain blockchain node on the blockchain platform system, the first blockchain node needs to query the list of the list type as the third company. Then the first blockchain node sends the query request information carrying the list of the third company to other blockchain nodes in the blockchain platform system through the broadcast mechanism. When the certain blockchain node receives the request information, Obtain the list of the third company in the requested information, compare and match the list with the list in the list database, and finally match the third company in the blacklist type, that is, query the third company as a blacklist type, and the blockchain The node sends the information that the queried third company is blacklisted to the first blockchain node, and can also send the third company’s province and its legal representative to the first blockchain node.

In one of the possible implementation manners, the first use right includes the use right to query the first data for free within a first preset time, and the first data is published by the first blockchain node to all The list data on the blockchain platform system; or, the first use right includes the use right of a first preset amount of digital currency or contribution value, and the digital currency or contribution value is used to pay for blockchain nodes The cost required for inter-transaction; or, the first use right includes the use right to query the list type of the second list for free within the second preset time.
