System based on a kind of list type queries method based on block chain that this programme embodiment that Fig. 1 is provided provides
A kind of list type queries method based on block chain, flow chart such as Fig. 2 institute of list type queries method is provided below in framework
Show.This method may comprise steps of:
Step the S101: the first block chain node passes through other block chain nodes of the broadcast mechanism into block platform chain system
Inquiry request is sent, the inquiry request carries the list for needing to inquire list type.
Specifically, list type includes blacklist, white list and gray list.Wherein, the blacklist may include reference
One or more in blacklist, industry blacklist, mechanism blacklist, fraud blacklist and law court's blacklist, if multinomial,
Then classification storage is convenient for inquiry；The gray list may include that not there is the net of reference to borrow to apply wantonly, is habitual overdue, more
The debt-credit of mechanism, family, look for multiple intermediaries to act on behalf, it is comprehensive be in debt it is excessively high, have and cheat loan tendency and have one or more in great number loaning bill history
The list of item behavior, if then classification storage is convenient for inquiry likewise, multinomial；The white list is except the blacklist and ash
List except list.
In a particular embodiment, the first block chain node and above-mentioned other block chain nodes are all to belong to the same block
Block chain node in platform chain system.First block chain node need in block platform chain system inquire list type be
Need to initiate a transaction, which is exactly other block chain nodes in the first block chain node request block platform chain system
The type for inquiring a certain specific list, if successful inquiring, the block chain node of successful inquiring can be rewarded, the reward
It can be the right to use of some operation.Specifically, block chain node broadcast name list type of the first block chain node near it
Inquiry request sends the solicited message for needing to inquire list type, which, which carries, needs to inquire list type
List information, the list information may include one or more lists for needing to inquire.Neighbouring block chain node receives this
After solicited message, but to its respectively near block chain node send the solicited message, constantly diffusive transport in this way is whole quickly
All block chain nodes of a block platform chain system all have received the solicited message.Specifically it may refer to Fig. 3, shown in Fig. 3
The only Partial Block chain node in block platform chain system, wherein node 1 is one in block platform chain system node,
Node near it has very much, can have node 2, node 3, node 4, node 6 and node 8 with the node of direct communication with node 1,
When node 1 needs to initiate the confirmation transaction of list type, will be broadcasted to node 2, node 3, node 4, node 6 and node 8
Solicited message is sent, and node 2, node 3, node 4, node 6 and node 8 establish after receiving solicited message to them
The node of communication sends solicited message, receives the node of solicited message like this constantly to it establishes the node broadcasts of communication
The solicited message is sent, all nodes of entire block platform chain system all have received the solicited message quickly.
Step S102: in the case where the list for needing to inquire list type is multiple, the first block chain link
Point receives the information that the confirmation first place list that the second block chain node is sent is first kind list.
Specifically, the first kind is any sort present on the second block chain node in a variety of list types
Type, first list are any one list in the multiple list, and the second block chain node is other areas
Any one node in block chain node, a variety of list types may include in blacklist, white list and gray list extremely
It is two kinds few.
In a particular embodiment, it when the list information that solicited message carries includes multiple lists for needing to inquire, receives
The block chain node of solicited message is one by one by multiple list for needing to inquire and itself publication in block platform chain system
List data library compares matching；If some block chain node just by it is multiple need the list inquired all match at
Function, then this can be known respectively by being stored in the database under the list of which type according to the list of successful match
Multiple types of lists for needing to inquire, in multiple list for needing to inquire, its list type of different lists can not phase
Together；Then, the list type information of this multiple list is sent to the first block chain node by the block chain node of the successful match,
Further, the block chain node of the successful match can also send the details for this multiple list stored in database
To the first block chain node.
Alternatively, receiving solicited message when the list information that solicited message carries includes multiple lists for needing to inquire
Block chain node by multiple list for needing to inquire and itself issues the list data library in block platform chain system one by one
Compare matching；If some block chain node just by multiple part list matching needed in the list inquired at
Function, then this can be known respectively by being stored in the database under the list of which type according to the list of successful match
The list type of part list, and another block chain node is by the list successful match of another part, then according to matching at
The list of function is stored under the list of which type the name that can know another part list respectively in the database
Single type；Then, which is sent to the first block chain node for the list type of the part list, further
, which can also be sent to the first block chain for the details for the part list stored in database
Node；On the other hand, which is sent to the first block chain link for the list type of another part list
Point, further, some block chain node can also send out the details for another part list stored in database
Give the first block chain node.
Alternatively, if some above-mentioned some list of block chain querying node is the list of some type, and it is above-mentioned another
A block chain node has also carried out comparison matching to some list, but compares matched the result is that some list is another
The list of a type, i.e. two block chain nodes are different to the list type for the list that the comparison matching of the same list obtains,
The result that so two block chain nodes can match self-contrast feeds back to the first block chain node.
There is also other possible embodiments, for example, if the list information that solicited message carries includes multiple needs
The list for inquiring list type, then can be completed jointly by more than two block chain nodes in block platform chain system
Inquiry, the process that each block chain node is specifically inquired are referred to foregoing description, and details are not described herein again.
In order to make it easy to understand, illustrating son to be illustrated.It specifically may refer to table 1.List data library includes in table 1
The list data of three kinds of list types, three kinds of list types are respectively blacklist, gray list and white list.Each list type
Under all store the company informations of multiple corresponding types, these company informations include province and enterprise where enterprise name, enterprise
The legal representative of industry actually can also include the unified social credibility code etc. of more company informations such as enterprise, if
Being can also include the information such as the illegal particular content of the violation that do of enterprise in the enterprise's list data library for belong to blacklist.
1 list data library 1 of table
Assuming that list data library shown in table 1 is that some block chain node issues the data in block platform chain system
Library, the list that the first block chain node needs to inquire list type is third company and the tenth company.So the first block chain link
Point carries third company list and the tenth by other block chain nodes transmission of the broadcast mechanism into block platform chain system
The inquiry request information of company's list, when some block chain link point receives the solicited message, in acquisition request information
Three company's lists and the tenth company's list match two lists with the list comparison in list data library, finally in black name
It is matched to third company in single type, the tenth company is matched in white list type, i.e., inquiry third company is blacklist class
Type, the tenth company be white list type, some block chain node will inquire third company be black list type information and
It has inquired the information that the tenth company is white list type and has been sent to the first block chain node, while can also be by third company and the
The information such as province and its legal representative are also sent to the first block chain node where ten companies.
2 list data library 2 of table
Another example, referring to Tables 1 and 2.Assuming that list data library shown in table 1 is that some block chain node is issued
Database in block platform chain system, it is flat in block chain that list data library shown in table 2 is that another block chain node is issued
Database in platform system；The list that first block chain node needs to inquire list type is third company and the 19th company.
So the first block chain node carries the by other block chain nodes transmission of the broadcast mechanism into block platform chain system
The inquiry request information of three company's lists and the 19th company's list, when some block chain link point receives the solicited message,
Third company list and the 19th company's list in acquisition request information, by the list in two lists and list data library
Comparison matching, is finally matched to third company in black list type, i.e., inquiry third company is black list type, but in data
It matches in library less than the 19th company, then, it is black list type which, which will only inquire third company,
Information is sent to the first block chain node, while can also be by the information such as province and its legal representative where third company
It is sent to the first block chain node.On the other hand, another block chain node of the solicited message is received, in acquisition request information
Third company list and the 19th company's list, by two lists in list data library list comparison match, finally
The 19th company is matched in gray list type, i.e., the 19th company of inquiry is gray list type, but is matched in the database
Less than third company, then, which only sends out the information that the 19th company of having inquired is gray list type
The first block chain node is given, while the information such as province and its legal representative where the 19th company can also also be sent
To the first block chain node.Two such block chain node completes looking into for the list type that list is carried in solicited message jointly
It askes.
In a wherein example, if receiving another block chain of the solicited message in above-mentioned another aspect
Node is finally matched to the 19th company in gray list type, i.e., the 19th company of inquiry is gray list type, and in data
Being matched to third company in gray list type in library, i.e., inquiry third company is gray list type, then, another block
Chain node can will inquire third company and the 19th company and be sent to the first block chain node for the information of gray list type,
