Detailed Description
In order to make the technical solutions better understood by those skilled in the art, 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, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. 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 application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
It should be noted that, the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for presentation, analyzed data, etc.) referred to in the present disclosure are information and data authorized by the user or sufficiently authorized by each party.
For a better understanding of the embodiments of the present application, some of the terms or expressions that appear during the description of the embodiments of the present application are to be interpreted as follows:
block chaining techniques: the distributed account book technology comprehensively utilizes the technologies of internet, point-to-point transmission, distributed computer storage, cryptography and the like, behaviors and data in a certain activity are distributed and stored in the distributed account book on a plurality of nodes of a blockchain network according to a blockchain protocol, and the behaviors and the data can be stored in the distributed account book only after being verified by the plurality of nodes together according to the blockchain protocol and effectively achieving consensus. Once the behavior information and the related data are stored in the distributed account book, the behavior information and the related data are difficult to change, the account book data on a certain node cannot be approved by other nodes in the blockchain network after being changed, and cannot be written into an account book commonly maintained by a plurality of nodes, namely, the change is invalid. Even in some special cases, more than 50% of nodes agree to a consensus and agree to update some data or behavior information, the updated behavior and history data will still be stored in the distributed ledger, and the change requires a lot of computing resources and time, making it difficult for a single person or organization to control the whole blockchain network alone to modify the distributed ledger. Meanwhile, data in the distributed account book can be transparent to the whole network, and nodes in any access block chain network can inquire historical data and behaviors. These characteristics of the blockchain ensure the integrity, irreparability, and transparency of the data information in the distributed ledger.
Intelligent contract: the program code stored and run on the blockchain network can be regarded as activity rules and related conventions commonly recognized by related parties participating in a certain activity, and the rules and conventions are expressed in the form of codes and are placed in the blockchain network for execution. The intelligent contracts, once agreed upon and placed on the blockchain network, are also transparent to all active participants and are not alterable. Intelligent contract execution procedures, status, input and output data may also be recorded in the blockchain network, unalterable and transparent to all active participants.
The solution of the present application is described below with reference to preferred examples.
Fig. 1 is a schematic structural diagram of an alternative blockchain-based drawing system according to an embodiment of the present invention, and as shown in fig. 1, the system may be divided into an application module 10 and a blockchain module 12, where:
the application module 10 is configured to issue an announcement of a drawing activity, where the announcement at least includes information of the drawing activity; obtaining the drawing information of a plurality of drawing objects participating in drawing activities, and storing the drawing information to a block chain module; determining a drawing rule of drawing activities, and storing the drawing rule to a block chain module in an intelligent contract form; and executing the intelligent contract, determining a lot-drawing object from the lot-drawing objects based on the lot-drawing information and the lot-drawing rule, obtaining a lot-drawing result, and storing the lot-drawing result to the block chain module. Optionally, the application module 10 may further respond to a query request of the target object, and feed back a query result corresponding to the query request, where the query request is used to request to query at least one of the following information: drawing activity information, drawing information and drawing results.
And the block chain module 12 is used for storing the drawing information, the intelligent contract corresponding to the drawing rule and the drawing result.
In some optional embodiments of the present application, the application module is mainly implemented by a Java program and is configured to process main business logic, the blockchain module is constructed based on a hyper-ledger framework (hyper-ledger Fabric), and the application module performs data interaction with the blockchain module by calling an interface corresponding to the hyper-ledger Fabric.
The HyperLegend Fabric is a private and licensed block chain architecture with high modularization, supports intelligent contracts written by various general programming languages, supports pluggable consensus protocols, and can be customized more effectively to adapt to specific use cases and trust models.
Specifically, the blockchain of the architecture is divided by organizations (organization), each organization has peer nodes bearing different functions, and each organization has a corresponding Fabric-CA server, and all organizations share one orderer cluster, where a node is a communication entity of the blockchain, which is a logical concept, and multiple nodes of different types can run on the same physical server, and generally, the nodes include the following four types:
1. common node peer: the peer nodes can be further divided into a bookkeeping node (commit peer), an endorsement node (endorser peer), a master node (leader peer) and an anchor node (anchor peer) according to the assumed roles.
Accounting node: all peer nodes are accounting nodes and are responsible for verifying transactions in the block of the sequencing service node and maintaining copies of state and general ledgers. The node periodically obtains blocks containing transactions from the ordering service node (orderer) and adds these blocks to the blockchain after verification of the block is issued. The accounting nodes can not be configured through the configuration file, and the related accounting nodes need to be manually specified when the current client or command line initiates a transaction request, and the number of the accounting nodes can be multiple.
An endorsement node: some peer nodes will also perform transactions and sign endorsements on the results, acting as endorsement nodes. The endorsement node is a dynamic role and is bound with a specific chain code. Each chain code sets an endorsement strategy when being instantiated, and specifies which nodes are effective for transaction after endorsement, and the endorsement nodes are only when an application program initiates a transaction endorsement request to the chain code, and are common accounting nodes at other times and only responsible for verifying the transaction and accounting. The endorsement node cannot be specified by the configuration file, but is specified by the client initiating the transaction request, and the number of the endorsement nodes can be more than one.
An anchor node: the peer node may also be an anchor node, which is primarily responsible for exchanging information on behalf of an organization with other organizations. Each organization has an anchor node, which is important for the organization, and if there is a problem with the anchor node, the current organization loses contact with other organizations. The configuration information of the anchor node is configured in a configuration file configx.yaml of the configxgen module, and only one anchor node is available.
A master node: the peer node can also be a master node, can communicate with the sequencing service node, and is responsible for acquiring the latest block from the sequencing service node and synchronizing the blocks inside the organization, and only one master node can exist in the whole organization.
2. Ordering service node orderer: and receiving the transaction containing the endorsement signature, sequencing the unpacked transactions to generate a block, and broadcasting the block to the peer node. The ordering service provides atomic broadcast to ensure that nodes on the same chain receive the same information and have the same logical order.
3. A client node: the client must be connected to a peer node or a sequencing service node to communicate with the blockchain network. And the client submits the transaction proposal to the endorsement node, and when enough endorsements are collected, the transaction proposal is broadcasted to the sequencing service node for sequencing to generate a block.
4. And (3) the CA node: the certificate authority of fabric1.0 consists of a server and a client. And the CA node receives the registration application of the client and returns a registration password for user login so as to obtain the identity certificate. All operations on the blockchain require verification of the user identity.
In some optional embodiments of the present application, the blockchain module includes at least two organizations and one ordering service node, and each organization includes at least: a Fabric-CA server, a billing node, an endorsement node, an anchor node, and a host node. Fig. 2 is a schematic diagram of an optional blockchain constructed based on the HyperLegendr Fabric, in which an application module (application) interacts with a blockchain module by calling an interface program (SDK).
Fig. 3 is a schematic diagram illustrating a more specific block chain-based drawing system. The application module can be divided into a front-end interactive interface and a rear-end application server, wherein the interactive interface is used for providing an operation and query interface for a participant so as to enable the participant to know relevant information in the drawing activity, transmit data to the application server and acquire query data; the application server deploys an application program, after receiving page structured information submitted by an interactive interface, the application server performs service logic processing, stores data (such as basic information of a user, an operation log and the like) which is not directly related to drawing and signing in a relational database, stores data (such as drawing and signing activity information, drawing and signing results and the like) which is related to drawing and signing in a block chain module, and can call an intelligent contract through an interface corresponding to Hyperhedger Fabric, and the intelligent contract directly interacts with the block chain to request for data query or data write-in.
On the basis of the drawing system, the embodiment of the application provides a drawing method based on a block chain, and the method can be applied to the existing drawing system and also can be used as an independent system to be in butt joint with various drawing activity systems and provide services. It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer-executable instructions and that, although a logical order is illustrated in the flowcharts, in some cases, the steps illustrated or described may be performed in an order different than presented herein.
Fig. 4 is a flowchart illustrating an alternative block chain-based drawing method according to an embodiment of the present application, where as shown in fig. 4, the method at least includes steps S402-S408, where:
step S402, issuing the notice of the drawing activity, wherein the notice at least comprises the information of the drawing activity.
It is understood that before the drawing activity starts, an announcement of the drawing activity may be issued by the application module, where the announcement includes at least: the system comprises drawing item information, drawing entry starting time, drawing entry ending time, drawing rules, preset drawing quantity, drawing result announcement time and other information related to drawing activities. For example, the drawing activity can be a commemorative coin selling drawing activity, and the drawing activity information at least comprises commemorative coin information, and specifically can comprise detailed information such as the face value, the specification weight, the material, the serial number and the like of the commemorative coin.
Step S404, obtaining the drawing information of a plurality of drawing objects participating in the drawing activity, and storing the drawing information to the block chain module.
In order to ensure fairness, after the lottery registration time is over, data participating in the lottery needs to be guaranteed to be unchangeable, so that the lottery process of the participant can be stored in the block link module, and since the data of the block link module has non-tamper-resistance property, the information of the participant can be prevented from being tampered by storing the lottery process of the participant in the block link module. In some optional embodiments of the present application, for any drawing object participating in drawing, at least the identity information and the drawing number of the drawing object are obtained, and the identity information and the drawing number are stored in the block chain module as the drawing information of the drawing object.
Step S406, determining a drawing rule of the drawing activity, and storing the drawing rule to the block chain module in an intelligent contract form.
In some optional embodiments of the present application, the following draw rule algorithm is provided:
1. and determining a preset base number A, the number X of participants who participate in the drawing and a preset middle drawing number M.
The preset base number a can be calculated by the following method: a ═ is (the Shenzhen stock exchange on the last working day of the drawing day is deeply certified to refer to "receive now" exponent × 100) × (the midplane in the Shenzhen stock exchange on the last working day of the drawing day is referred to "receive now" exponent × 100) × 10000; and the historical index quotation query related data of the Shenzhen stock exchange website can be logged, and finally A is an integer and cannot have decimal places.
2. And arranging the digits of the preset base number A in a reverse order to obtain the turnover number B.
3. Calculating the remainder of the quotient of the turnover number B and the number X of the participators, and adding 1 to obtain the initial middle signature number Y1。
4. And calculating the quotient of the number of participating people X and the preset middle-signed number M and rounding to obtain the order Z.
5. Based on the number Y of the initial middle label1And sequentially determining M preset middle sign numbers according to the order Z, wherein the Nth middle sign number YN＝Y1And N-1 × Z, (N is more than or equal to 1 and less than or equal to M), and the drawing object corresponding to the drawing information matched with the drawing number is the drawing object.
It should be noted that in some cases, the Nth middle-signed number Y may appearNIf the number of participants is more than X, taking N middle-sign numbers YN＝Y1+(N-1)*Z-X。
The drawing rule algorithm is deployed in the block chain module in advance in the form of an intelligent contract, and the drawing can be ensured to be performed according to a set rule by using the characteristic that the block chain cannot be tampered.
Step S408, executing the intelligent contract, determining a drawing object from the plurality of drawing objects based on the drawing information and the drawing rule, obtaining a drawing result, and storing the drawing result to the block chain module.
Specifically, on the premise of meeting the drawing rules, the application module can call the intelligent contract through an interface corresponding to the Hyperhedger Fabric, and execute the drawing rules to obtain the drawing numbers with the preset drawing number; and then, determining the medium-sign objects with the preset medium-sign number based on the medium-sign numbers to obtain the drawing result. Because the block chain module has the characteristic that data cannot be tampered, the drawing and signing result is stored in the block chain module, and the tracing effect on historical data can be achieved.
Optionally, after the middle sign object is determined, a binding relationship between the commemorative coin information and the middle sign object can be established, and the binding relationship is stored in the blockchain module, for example, the number information of the commemorative coin and the identity information of the middle sign object are bound and stored in the blockchain module, so that the situation that the commemorative coin is sold backwards can be reduced to a great extent.
In order to ensure the openness and transparency of the whole drawing process, the data generated in the whole drawing process can be inquired. Specifically, the application module may respond to a query request of the target object and feed back a query result corresponding to the query request, where the query request is at least used for requesting to query one of the following information: drawing activity information, drawing information and drawing results. For example, the drawing participant can query the relevant block information through the interactive interface provided by the application module to know whether the intelligent contract is modified or not, whether the drawing data of the participant is correct or not, whether the intelligent contract is correctly executed or not, and the final drawing result.
In the embodiment of the application, the drawing rules are deployed in the block chain module in an intelligent contract mode, so that drawing can be carried out according to the rules, and the possibility that human factors interfere drawing results is eliminated; the data of the drawing process and the drawing result are stored in the block chain module, so that the drawing data can not be tampered, and the transparence of the drawing process is ensured; by using the mode of multiple accounts, the realization mode of the traditional business system for storing business data in a centralized way is avoided, and the safety of the data is improved; the method and the device effectively solve the technical problems that the existing drawing method is not transparent enough and cannot ensure the fairness of drawing.

Before the drawing activity begins, the publishing module 50 may publish a drawing activity advertisement, which includes at least: the system comprises drawing item information, drawing entry starting time, drawing entry ending time, drawing rules, preset drawing quantity, drawing result announcement time and other information related to drawing activities. For example, the drawing activity can be a commemorative coin selling drawing activity, and the drawing activity information at least comprises commemorative coin information, and specifically can comprise detailed information such as the face value, the specification weight, the material, the serial number and the like of the commemorative coin.
The obtaining module 52 is configured to obtain the drawing information of the plurality of drawing objects participating in the drawing activity, and store the drawing information in the blockchain module.
In some optional embodiments of the present application, for any drawing object participating in drawing, the obtaining module 52 at least obtains the identity information and the drawing number of the drawing object, and stores the identity information and the drawing number as the drawing information of the drawing object in the block chain module. Specifically, in order to ensure fairness, after the end of the drawing registration time, data participating in drawing needs to be guaranteed to be unchangeable, and therefore, the drawing process of the participant can be stored in the blockchain module, and since the data of the blockchain module has non-tamper property, by storing the drawing process of the participant in the blockchain module, the information of the participant can be prevented from being tampered.
