All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein.

The technical means of the present invention will be described in detail with reference to specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
FIG. 1 is a first block chain structure according to an embodiment of the present invention; FIG. 2 is a block chain structure diagram of the second embodiment of the present invention; fig. 3 is a flowchart illustrating a data flow processing method based on a block chain according to an embodiment of the present invention.
The method according to this embodiment is implemented based on the blockchain, and further, it can be applied to any node of the blockchain.
Taking fig. 1 as an example, the blockchain may have a plurality of nodes 100, each of which may be an electronic device, and specifically, may be an electronic device with certain data processing capability and data storage capability. It may be a terminal, for example: the mobile phone, the computer, the tablet computer, and the like can also be a server, and meanwhile, a single node can be a single terminal or a server, or a combination of multiple terminals, a combination of multiple servers, or a combination of a terminal and a server.
Further, the nodes 100 in the blockchain may be used to implement distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like.
The method according to the present embodiment may be applied to any one of the nodes 100 shown in fig. 1.
In addition, taking fig. 2 as an example, some of the nodes 201 may be separate nodes without being connected to or communicating with other devices, some of the nodes 202 may be connected to or networked with other devices, and further, the nodes 202 may be centralized platforms capable of communicating with other devices 203 or the nodes 201; in other examples, node 202 may also be a device that connects to other centralized platforms.
The method according to this embodiment may be applied to any one of the nodes 202 and 201 shown in fig. 2.
Referring to fig. 3, the method for processing a data flow based on a block chain, applied to any one of nodes in the block chain, includes:
s11: acquiring a purchase request;
s12: determining order information of a target order according to the purchase request;
s13: and deploying the intelligent contracts corresponding to the target orders in the block chain by using the expense permit so that the block chain can execute circulation events of all the sub orders according to the intelligent contracts.
The purchase request in step S11 may be understood as a request for characterizing the buyer node to purchase the target data. In one example, the purchase request may be generated and obtained by a node implementing the method, that is: the node implementing the method is a buyer node, and in another example, the purchase request may be generated by other nodes and then sent to the node implementing the method to be acquired by the node; in another example, the purchase request may also be generated by a device outside the blockchain, and sent to the node implementing the method to be acquired.
Taking fig. 2 as an example, in the implementation process, if the method is applied to the node 202, the node 202 may receive a purchase request from another device 203, may directly generate the purchase request at the node 202 to obtain the purchase request, and may also receive the purchase request from another node 201 in the blockchain.
In addition, this embodiment does not exclude an implementation in which the node implementing the method is a seller node or a buyer node.
In the purchase request, target data information for characterizing the target data and buyer information for characterizing the buyer node may be carried. Further, the target data information and the customer information can be directly used when the order information is specified.
In step S12, N sub-orders are configured in association with the target order, where each sub-order is used to represent a flow event between a buyer node and a seller node related to at least one group of data content in the target data; wherein N may be an integer greater than or equal to 2.
Furthermore, all the sub-orders of one buyer and a plurality of sellers can be integrated into one target order, and then, only an intelligent contract needs to be deployed based on the target order, and the intelligent contract can supervise the execution of all the circulation events in the target order on the execution block chain.
The intelligent contract can be understood as being used for supervising and ensuring that the logic defined in the intelligent contract can be accurately implemented, and meanwhile, the intelligent contract can be deployed in a block chain. Therefore, the deployed intelligent contract may define the circulation logic of each circulation event, and since the present embodiment is applied to data circulation, the circulation logic of each circulation event mainly relates to delivery of data and payment of fees, for example: if the seller node delivers the data, payment of the contracted fee may be triggered, and/or: and triggering the seller node to deliver the data if the delivery of the appointed fee is completed. Furthermore, because the logic in the data flow events is uniform, the flow logic of each flow event can be the same in the specific implementation process.
In other examples, the above target order may also be associated with only one sub-order, that is: n may also be 1, and at this time, an intelligent contract associated with only one sub-order may be deployed, so that the block chain can execute the circulation of the sub-order according to the intelligent contract.
In addition, the circulation logic only defines a cause and effect on the logic, and if circulation needs to be realized, the specific contents of circulation need to be combined, so the intelligent contracts of the deployed persons also record the order information of the target orders.
The order information therein may be understood as any information associated with the target order and its sub-orders. The order information of the target order can be recorded in the intelligent contract deployed in the step S13, so that the execution of the intelligent contract can ensure that the circulation event represented by the order can be smoothly executed.
In one embodiment, the order information may include circulation status information of each sub-order; the circulation state information can be understood as representing the execution progress of the corresponding circulation event; in a specific implementation process, the circulation state information may include at least one of the following:
the order has established the state of the intelligent contract to be deployed;
a status to be paid;
a status of the data to be delivered;
a state of completion of the circulation event;
the state of event timeout is transferred.
As can be seen, before the intelligent contracts are deployed to the blockchain, the circulation state information in the intelligent contracts may be: the order already creates a state of the intelligent contract to be deployed, and after the intelligent contract is deployed to the blockchain, if the buyer needs to pay the fee is defined in the circulation logic of the intelligent contract, the order is as follows: the circulation state information in the intelligent contract may be: in the state to be paid, whether the buyer node completes the payment of the total amount cost corresponding to the target order or not can be monitored, and whether the buyer node completes the payment of the amount cost corresponding to the sub-order or not can be monitored in other examples; if the seller delivery data is defined in the circulation logic of the intelligent contract, then: the circulation state information in the intelligent contract may be: a status of the data to be delivered; if the required payment is completed and/or the delivery of the data is completed, the circulation status information in the intelligent contract may be: a state of completion of the circulation event; if the payment and delivery are not completed in the preset time, the circulation state information in the intelligent contract may be: the state of event timeout is transferred.
In one embodiment, the circulation state information in the intelligent contract can be updated according to the actual execution progress of each circulation event. The general evidence for information updating needs to be consumed, however, the general evidence for information updating needs to be consumed by the intelligent contract is far less than the general evidence for information updating needs to be consumed by deploying the intelligent contract, and the general evidence for information updating needs to be specifically understood as follows: the pass-certificate consumed by updating the circulation state information of all circulation events and the pass-certificate consumed by deploying one intelligent contract are always smaller than the pass-certificates consumed by respectively deploying the intelligent contracts for all circulation events.
Therefore, although the information updating also consumes the evidence, under the condition that only one intelligent contract is deployed, the evidence consumed in the whole circulation process can be effectively reduced, and the lower overhead cost is ensured.
For example: creating an intelligent contract, even if creating an empty intelligent contract which does not contain any logic, 100 general proofs may be spent, but updating the created intelligent contract may only cost 5 general proofs, and further, taking 5 orders as an example, if 5 intelligent contracts are deployed, at least 500 is spent even if no updating is done; if only 1 intelligent contract is created, 120 passes are spent on creation (120 passes are used instead of 100 passes because the 1 intelligent contract contains information of 5 sub-orders and needs more expenses), and then 5 passes are spent on each update, and the whole circulation event may be within 150.
The pass to which step S13 and the above description refer may be understood as Token, which may also be characterized as signaling, pass through, etc., which may be applied to rights, encryption, and circulation in the blockchain.
In one embodiment, the order information further includes at least one of:
seller information used for representing seller nodes in each circulation event; which may be at least one of a name of the seller, a unit/person identification, and other information that may be used to describe the seller, for example;
the data metadata are used for representing the data content required to be delivered by the seller node in each circulation event; the information may be any information describing the data content, for example, information describing the function of the data content, such as lane data, video data, and the like, or information describing the source of the data content, such as data from a certain company, data from a certain region, and the like; but also, for example, information describing the generation time of the data content, and at least one of any of the above listed may be used as the data meta information;
the sub-order amount information is used for representing the amount of money required to be paid by each circulation event; it may be a pre-calibrated amount, for example, pre-calibrated prices of data contents, and recorded by a list, or may be an amount specified by a seller or buyer;
the buyer information is used for representing the buyer node of the target order; which may be, for example, at least one of a buyer's name, entity/personal identification, and other information that may be used to describe the buyer;
target data information for characterizing the target data.
Fig. 4 is a flowchart illustrating step S12 according to an embodiment of the present invention.
Referring to fig. 4, in order to facilitate determination of the above information, step S12 may include, for example:
s121: and determining the seller information and the data element information according to the target data represented by the purchase request and the corresponding relation between different data contents and different nodes.
The corresponding relationship between different data contents and different nodes may be pre-recorded in the blockchain or the node implementing the method, and further, after the purchase request is obtained, the seller node from which the corresponding data content is purchased may be known. In the specific implementation process, the corresponding relations between different data contents and different nodes can be pre-recorded in a list manner.
Step S12 may also include, for example:
s122: and determining the sub-order amount information according to the price of each data content which is determined in advance.
The price may be pre-recorded in the blockchain or a node implementing the method, for example, the price of the data content of each seller may be pre-calibrated, and the price may be a calibrated total price, which is determined as order amount information; the order amount information may be a unit price, and further, the order amount information may be determined based on the unit price and the data amount of the data content.
In another embodiment, the bidding price may be specified by the buyer in the purchase request, and is predetermined, that is: the purchase request may include the above priced related information. In another embodiment, the bidding price may be predetermined after querying the corresponding seller node.
The buyer information and the target data information may be information directly described in the purchase request. And can be directly recorded when determining order information.
The steps S121 and S122 may be alternatively or both implemented.
In summary, in the data flow processing method and apparatus based on the blockchain and the blockchain system provided in this embodiment, all sub-orders of a buyer and a plurality of sellers can be integrated into one target order, and then, only an intelligent contract needs to be deployed based on the target order, and the intelligent contract can supervise execution of all flow events in the target order in the execution blockchain.
