Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram illustrating an architecture of a blockchain network according to an embodiment of the present disclosure. The blockchain network includes a plurality of nodes, e.g., node a, node b, node c, etc., and runs distributed applications. Each node may have and communicate with a respective database.
The block chain is a data structure for storing transactions, is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace leaving in the whole process, traceability, collective maintenance, public transparency and the like. A blockchain network is a computing node structure used to manage, update, and maintain one or more blockchain structures. The blockchain network may be a public blockchain network, a private blockchain network, or a federated blockchain network.
Decentralized Application (DAPP), also known as distributed Application, refers to an Application in which an Application program is distributed on different blockchain nodes in a blockchain network and depends on a bottom-layer blockchain platform and a consensus mechanism to jointly complete a task. DAPP is an internet application that differs from traditional applications by: the DAPP runs in a blockchain network, the blockchain network is a decentralized network, and the DAPP can be completely controlled without a centralized node; traditional applications are centralized and require a server to obtain data, process data, etc.
For a user of each node in the blockchain network, if the user needs to access the DAPP, the user needs to download a browser for accessing the DAPP, and the user accesses the DAPP through the browser. That is, the node needs to be installed with a browser for accessing the DAPP in order to go to the DAPP for access.
In fig. 1, the DAPP runs on a blockchain network, and any one of nodes in the blockchain network, for example, any one of node a, node b, node c, etc., can access the DAPP or perform other operations through the DAPP.
Wherein, the node a, the node b, the node c, etc. may be a computer device accessing a blockchain network, including but not limited to a smart phone, a tablet computer, a personal computer, a server, a private cloud, a public cloud, etc. The node a, the node b, the node c, and the like may also be a user accessing the block chain network through the computer device, and may be determined specifically according to an actual application scenario, and are not limited herein.
Smart contracts are a computer protocol intended to propagate, validate or execute contracts in an informational manner, allowing trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. An intelligent contract is a set of commitments defined in digital form, including the protocol on which the contract participants can execute the commitments, and is a piece of code written on a blockchain.
The data provider may be any node in the blockchain network, for example, node a; the data using end can be any node except the data using end in the block chain network, for example, the node b. The specific value can also be determined according to the actual application scenario, and is not limited herein.
Referring to fig. 2, fig. 2 is a schematic flow chart illustrating a data usage pricing method applied to a data usage terminal according to an embodiment of the present application, where the data usage pricing method may include the following steps:
s101, acquiring a price matrix through a decentralized application.
The data provider may be a data management department, which is any node in the blockchain network, for example, the node a is a data provider and is a device of an internet listening book platform accessing the blockchain network. The database in communication with the data provider is used to store data owned by the data provider, and may be, for example, an audio content library, a user information library, a user listening-to-book behavior library, a blacklist library, or the like. The following embodiment will be described by taking a user's book listening behavior library as an example.
The data providing end can determine an open data packet which can be provided in an open mode from the database in advance, and establish a price matrix of the open data packet to be issued to the block chain network.
Since the blockchain network comprises a plurality of nodes, each node is possibly a data provider, and the price matrix for opening the data packet in the database of the blockchain network can be issued to the blockchain network. Therefore, a plurality of price matrixes are issued in the block chain network, and the price matrixes are opened to all nodes in the block chain network.
The open data package refers to data resources which can be openly provided in a database of a data providing terminal, for example, the database is a user listening behavior library and is used for storing various behavior tables of a user during listening to a book using the internet listening platform, for example, a browsing content table, a collection audio table, a search audio table, an order table, a purchase album table, and the like. The open data packet may be a behavior table, such as a list table, which can be openly provided in the user book listening behavior library.
For an open packet, there may be at least one price matrix. Each price matrix issued in the block chain network has its own identification information, which refers to information that can uniquely refer to an open data packet, such as a table name, a storage address, and the like.
When the data using end has data requirement, all price matrixes issued in the block chain network can be searched through the DAPP, and the price matrix meeting the requirement of the data using end is selected according to the identification information. For example, if the data user needs to analyze the book listening behavior of the user, the price matrix of the "listening list table" referred by the identification information may be selected and obtained.
S102, generating a data retrieval request based on the price matrix.
The price matrix is used for representing pricing information of the open data packet provided by the data providing end, and the pricing information can comprise the total number of data of the open data packet, all fields, retrieval conditions, ladder pricing of each field and the like.
The total number of data items is the total number of data items in the open packet, and can be represented by N. All fields refer to which fields are contained in the open data packet and can be represented by f1, f2 and f3 … … fn, wherein f1, f2 and f3 … … fn refer to information capable of uniquely referring to each field in the open data packet, such as field names, field numbers and the like. The search condition refers to whether each field in the open packet supports conditional screening, for example, f1 supports screening, f3 does not support screening, and the like. The pricing rate of each field is the pricing rate of each field when the number of data bars is different, for example, <1000, 1001-10000, 10001-50000, >50000 and the like, and the pricing rate of each field can be respectively represented by p1, p2 and p3 … … pn, wherein p1, p2 and p3 … … pn are different when the number of data bars is different.
For example, the price matrix is shown in table 1 below:
TABLE 1
And the data using end accesses the block chain network through the DAPP, and can generate a data retrieval request based on the price matrix after acquiring the price matrix meeting the self requirement.
The data retrieval request includes at least one selected field, and a data screening condition for each selected field. That is, the data consumer selects the required data from the open data packet based on the total number of data, all fields, search conditions, and ladder pricing of each field, for example, f1, f2, fn, and f1>18, f2 ═ abc ", where the data filtering conditions of the selected fields are f1, f2, fn, and f1 fields are all the data >18 under the field, the data filtering conditions of the f2 field are all the data" abc "under the field, and the data filtering conditions of the fn field are all the data under the field.
S103, calling the intelligent contract to send the data retrieval request to the data providing end so that the data providing end obtains the target data from the open data packet according to the data retrieval request and returns the number of the target data to the intelligent contract.
The data using end takes DAPP as a program for selecting the price matrix, calculating the price of the target data and acquiring the target data.
After the data using end generates the data retrieval request based on the price matrix, the intelligent contract can be called through the DAPP, and the data retrieval request is sent to the data providing end. The data providing end performs data screening on the open data packet according to the data retrieval request, namely, performs data screening on each selected field according to each selected field in the data retrieval request and the data screening condition of each selected field, and target data can be obtained after the screening is completed; and then, the data providing end counts the number of the target data and returns the number of the target data to the intelligent contract. The number of pieces of target data may be represented by n, for example, where n is 12000.
And S104, calling an intelligent contract to calculate the price according to the number of the target data and the price matrix to obtain the price of the target data.
The data providing end issues the price matrix of the open data packet to the blockchain network, and meanwhile, the price calculation mode of the open data packet needs to be issued to the blockchain network in an intelligent contract mode.
And after the data providing end returns the number of the target data to the intelligent contract, the data using end calls the intelligent contract through the DAPP, and the intelligent contract carries out price calculation according to the number n of the target data and the price matrix according to the price calculation mode of the open data packet, so that the price of the target data can be obtained. The price of the target data may be denoted by P.
That is, the pricing of each selected field when the number of the data pieces is n is determined from the price matrix according to the number n of the target data, for example, n is 12000, and the pricing of the selected fields f1, f2 and fn when the number of the data pieces is n is p1(10001 to 50000), p2(10001 to 50000) and pn (10001 to 50000), respectively; then, calculating the sum of pricing of each selected field when the number of the data pieces is n, namely p1 (10001-50000) + p2 (10001-50000) + pn (10001-50000), and then obtaining the price of one piece of data; and finally, multiplying the price of the piece of data obtained in the last step by the number n of the target data to calculate the price of the target data.
For example, taking n 12000 as an example, and combining with the price matrix shown in table 1, the price of the target data is: p is [ P1 (10001-50000) + P2 (10001-50000) + pn (10001-50000) ] × n.
After calculating the price of the target data, the intelligent contract can return the number and the price of the target data to the data consumer, so that the data consumer can decide whether the target data needs to be purchased.
The steps S102, S103, and S04 will be described in detail below.
Optionally, the price matrix includes the total number of data pieces of the open data packet, all fields, the search condition, and the ladder pricing of each field. Thus, step S102 may comprise the following sub-steps:
and S1021, generating a data retrieval request based on the total number of the data, all the fields, the retrieval conditions and the step price of each field, wherein the data retrieval request comprises at least one selected field and the data screening conditions of each selected field.
Combined with table 1, the data consumer can obtain the total data amount N of the open data packet, for example, 60000 pieces, based on the price matrix; meanwhile, from the self-requirement, the required fields, such as f1, f2 and fn, can be selected from the fields f1, f2 and f3 … … fn; the number of data pieces which can be accepted by the user can be determined in the selection process by combining the ladder pricing of each field, for example, 12000 data pieces; further, depending on the search condition, that is, whether or not each field in the open packet supports screening, a data screening condition is set for the selected field, for example, f1>18, f2 ═ abc, or the like. In this way, data retrieval requests can be generated, i.e., f1, f2, fn, and f1>18, f2 being "abc".
Optionally, the data providing end provides an application programming interface, and the data providing end provides the data screening service through the application programming interface. Thus, step S103 may comprise the following sub-steps:
s1031, calling the intelligent contract, sending the data retrieval request to an application programming interface, so that the data providing end completes data screening of each selected field in the open data packet according to the at least one selected field and the data screening condition of each selected field to obtain target data, and returning the number of the target data to the intelligent contract;
the input of the application programming interface is a data retrieval request, and the output is the number of target data meeting the data retrieval request.
An Application Programming Interface (API), also called API, is a set of definitions, programs and protocols, and implements the mutual communication between computer software through the API. One of the primary functions of an API is to provide a common set of functions. The API is also a middleware and provides data sharing for various platforms.
The data provider may pre-access the open data packet to the blockchain network and open an API interface of the data screening service to the blockchain node service. The input parameter of the API interface is a data retrieval request which can be represented by x; the output result is the number n of pieces of target data satisfying the data retrieval request.
The data using end obtains the price matrix through the DAPP access block chain network, and generates a data retrieval request x based on the price matrix, wherein the content of x is as follows:
x ═ f1>18, f2 ═ abc ", the result retaining the f1, f2, fn fields.
Then, the data using end calls an intelligent contract through the DAPP, and inputs a data retrieval request x into the intelligent contract as a parameter; the intelligent contract sends the data retrieval request x to an API (application programming interface) of a data providing end for providing data screening service through the block link node service; and the data screening service of the data providing end completes the data screening of the open data packet according to the data retrieval request x to obtain target data meeting the data retrieval request x, and obtains the number n of the target data to return to the intelligent contract.
Alternatively, on the basis of fig. 2, please refer to fig. 3, step S104 may include the following sub-steps:
s1041, determining a target number interval including the number of pieces of the target data from the plurality of preset number intervals.
In the price matrix. The ladder pricing of each field comprises a plurality of pricing and a preset number interval associated with each pricing, for example, in combination with table 1, for the f1 field, the ladder pricing comprises 4 pricing including p1(<1000), p1 (1001-10000), p1 (10001-50000) and p1(>50000), and the 4 pricing can be completely different or one or more of the same. The preset number intervals associated with these 4 pricing intervals are in turn: <1000, 1001-10000, 10001-50000 and > 50000.
Assuming that the number n of pieces of target data returned to the intelligent contract by the data providing end is 12000, determining that the target number interval is 10001-50000 from a plurality of preset number intervals.
S1042, determining the target pricing of each selected field from the price matrix according to the target number interval.
Taking n 12000 as an example, for the selected fields f1, f2, fn, the target pricing determined from the price matrix is as follows: p1 (10001-50000), p2 (10001-50000) and pn (10001-50000).
And S1043, calling an intelligent contract, and calculating the price according to the number of the target data and the target pricing of each selected field to obtain the price of the target data.
And the block chain network is provided with a price calculation mode of an open data packet in an intelligent contract mode. After the data using end determines the target pricing of each selected field, the intelligent contract can be called through the DAPP, and the price of the target data can be calculated. Taking n as 12000 as an example, the price of the target data finally calculated is:
P＝[p1(10001～50000)+p2(10001～50000)+pn(10001～50000)]*n。
after calculating the price of the target data, the intelligent contract may return the number n and the price P of the target data to the data consumer, and the data consumer may evaluate whether the price is acceptable, and then decide whether to use the target data.
Therefore, referring to fig. 4 on the basis of fig. 2, after step S104, the data usage pricing method may further include steps S105 to S107.
And S105, evaluating the price of the target data to determine whether to use the target data.
And S106, when the target data is determined to be used, sending a data acquisition request to the data providing terminal through the decentralized application.
