The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

Before further detailed description of the embodiments of the present invention, terms and expressions referred to in the embodiments of the present invention will be described, and the terms and expressions referred to in the embodiments of the present invention will be explained as follows.

1) Transactions (transactions), equivalent to the computer term "Transaction," include operations that need to be committed to a blockchain network for execution and do not refer solely to transactions in the context of commerce, which embodiments of the present invention follow in view of the convention colloquially used in blockchain technology.

For example, a deployment (deployment) transaction is used to install a specified smart contract to a node in a blockchain network and is ready to be invoked; the call (Invoke) transaction is used to add a record of the transaction in the blockchain by calling an intelligent contract, and to perform operations on the state database of the blockchain, including update operations (including adding, deleting, and modifying Key-Value pairs in the state database) and query operations (i.e., querying Key-Value pairs in the state database).

2) Block Chain (Block Chain) is an encrypted, chained transactional memory structure formed from blocks (blocks).

For example, the header of each block may include hash values of all transactions in the block, and also include hash values of all transactions in the previous block, so as to achieve tamper resistance and forgery resistance of the transactions in the block based on the hash values; newly generated transactions, after being filled into the tiles and passing through the consensus of nodes in the blockchain network, are appended to the end of the blockchain to form a chain growth.

3) A Block Chain Network (Block Chain Network) incorporates a new Block into a set of a series of nodes of a Block Chain in a consensus manner.

4) Ledger (legger) is a general term for blockchains (also called Ledger data) and state databases synchronized with blockchains.

Wherein, the blockchain records the transaction in the form of a file in a file system; the state database records the transactions in the blockchain in the form of different types of Key (Key) Value pairs for supporting quick query of the transactions in the blockchain.

5) Intelligent Contracts (Smart Contracts), also called Chain codes (Chain codes) or application codes, are programs deployed in nodes of a blockchain network, the programs are triggered to be executed according to conditions, and the nodes execute the intelligent Contracts called in received transactions to update or inquire key value pair data of a state database.

6) Consensus (Consensus), a process in a blockchain network, is used to agree on transactions in a block among a plurality of nodes involved, the agreed block is to be appended to the end of the blockchain, and the mechanisms for achieving Consensus include Proof of workload (PoW, proof of Work), proof of rights and interests (PoS, proof of equity (DPoS), proof of granted of shares (DPoS), proof of Elapsed Time (PoET, proof of Elapsed Time), and so on.

7) The public blockchain is a blockchain which can be read by anyone all over the world, can send a transaction, can effectively confirm the transaction, and can participate in a consensus verification process, wherein the consensus process determines which block can be added into the blockchain and defines the current state.

8) Private blockchain, refers to a blockchain whose write rights are in only one organization's hand. The read right is either open to the outside or is limited to any extent.

9) And the alliance blockchain refers to a blockchain of which the consensus process is controlled by a preselected node. A federated blockchain may be considered to be a blockchain that is commonly operated by many organizations or organizations, each of which manages one or more nodes in the federated chain.

10 In response to, indicating a condition or state on which the performed operation depends, one or more of the performed operations may be in real-time or may have a set delay when the dependent condition or state is satisfied; there is no restriction on the order of execution of the operations performed unless otherwise specified.

Referring to fig. 1, fig. 1 is a schematic diagram of an optional application architecture of the information processing system 100 based on the blockchain network provided in the embodiment of the present invention, and to implement an exemplary application supported by the information processing system 100 based on the blockchain network, the information processing system 100 based on the blockchain network includes a blockchain network 200 (where a plurality of common identification nodes 210, illustratively showing a common identification node 210-1, a common identification node 210-2, and a common identification node 210-3, are deployed in the blockchain network 200), an event management platform 300, an authentication center 400, a service agent 500 (illustratively showing a terminal 500-1 belonging to the service agent 500 and a graphical interface 510-1 thereof), and a service agent 600 (illustratively showing a terminal 600-2 belonging to the service agent 600 and a graphical interface 610-2 thereof), where respective portions of the information processing system 100 based on the blockchain network are described below.

The type of the blockchain network 200 is flexible and may be any one of, for example, a public blockchain (referred to as a public chain), a private blockchain (referred to as a private chain), or a federation blockchain (referred to as a federation chain). Taking a public link as an example, electronic devices such as user terminals and servers of any service entity can access the blockchain network 200 without authorization; taking a federation chain as an example, electronic devices (e.g., user terminals and servers) under the jurisdiction of a service entity after authorization may access the blockchain network 200, and in this case, the service entity may become a client node in the blockchain network 200.

In some embodiments, the client node may act as a mere watcher of the blockchain network 200, i.e., provide functionality that supports the initiation of transactions by the business entity (e.g., for uplink storage of data or querying of data on the chain), and may be implemented by default or selectively (e.g., depending on the specific business requirements of the business entity) for the functions of the consensus node 210 in the blockchain network 200, such as a ranking function, a consensus service, and an accounting function, etc. Therefore, the data and the service processing logic of the service subject can be migrated to the blockchain network 200 to the maximum extent, and the credibility and traceability of the data and service processing process are realized through the blockchain network 200.

The consensus node 210 in the blockchain network 200 receives transactions submitted from terminals (e.g., terminal 500-1 shown in fig. 1 as belonging to business entity 500 and terminal 600-2 shown in fig. 1 as belonging to business entity 600) of different business entities (e.g., business entity 500 and business entity 600 shown in fig. 1), performs the transactions to update the ledger or query the ledger, and various intermediate or final results of performing the transactions may be returned to the user interfaces (e.g., graphical interface 510-1 of terminal 500-1 and graphical interface 610-2 of terminal 600-2) of the business entity's terminal for display.

An exemplary application of the blockchain network is described below, taking as an example that a plurality of service entities access the blockchain network to implement management of an event.

Referring to fig. 1, a plurality of business entities involved in the management of the event provided in the embodiment of the present invention, for example, a business entity 500 may be a party to be participated in, a business entity 600 may be an event host, different business entities (for example, the business entity 500 and the business entity 600) respectively register with a Certificate Authority (CA) 400 to obtain respective digital certificates (including a public key of the business entity and a digital signature signed by the CA on the public key and identity information of the business entity), attach to a transaction together with a digital signature of the business entity for the transaction, and send the transaction to the blockchain network 200. Wherein after different business entities obtain authorization from the event management platform 300, clients running on the business entity's devices (e.g., user terminals or servers) can request access from the blockchain network 200 to become client nodes.

The business personnel of the business agent 500 logs in the client of the terminal 500-1, inputs the user personal information or the game result query request, the user personal information or the game result query request is sent to the event management platform 300, the event management platform 300 generates a transaction corresponding to the updating operation or the query operation according to the user personal information or the game result query request, an intelligent contract required to be called for realizing the updating operation or the query operation and parameters (such as identity information of the business agent 500) transmitted to the intelligent contract are specified in the transaction, the transaction also carries the digital certificate of the client of the terminal 500-1, namely the business agent 500 and the signed digital signature (for example, the digital certificate of the client of the terminal 500-1 is used for encrypting the summary of the transaction, and the business agent 500 can register with the authentication center 400 to obtain the digital certificate), and broadcasts the transaction to the consensus node 210 in the blockchain network 200.

When receiving a transaction, the consensus node 210 in the blockchain network 200 verifies the digital certificate and the digital signature carried in the transaction, and after both are successfully verified, confirms whether the business agent 500 has a transaction right according to the identity information of the business agent 500 carried in the transaction, and the transaction fails due to any verification result of the digital signature and the right verification. After the rights verification succeeds, consensus node 210 signs its digital signature (e.g., by encrypting a digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After receiving the transaction successfully verified, the consensus node 210 in the blockchain network 200 fills the transaction into a new block and broadcasts the new block. When broadcasting a new block, the consensus node 210 in the block chain network 200 performs a consensus process on the new block, and if the consensus is successful, adds the new block to the tail of the block chain stored in the consensus node, updates the state database according to the transaction result, and executes the transaction in the new block: for the transaction of submitting and updating the personal information of the user, updating the key value pair corresponding to the personal information of the user in the state database; and for the transaction of inquiring the updated competition results, inquiring the key value pair corresponding to the updated competition results from the state database, and returning a transaction result.

Similarly, a service person of the service agent 600 logs in the client of the terminal 600-2, inputs the historical competition information or the electronic certificate data query request of the party to be participated in, the historical competition information or the electronic certificate data query request of the party to be participated in is sent to the event management platform 300, the event management platform 300 generates a transaction corresponding to the updating operation or the query operation according to the historical competition information or the electronic certificate data query request of the party to be participated in, specifies an intelligent contract required to be called for realizing the updating operation or the query operation and parameters transferred to the intelligent contract in the transaction, and also carries the digital certificate of the client of the terminal 600-2 and a signed digital signature (for example, the summary of the transaction is obtained by encrypting the digital certificate of the client of the terminal 600-2) in the transaction), and broadcasts the transaction to the consensus node 210 in the block chain network 200.

When receiving a transaction, the consensus node 210 in the blockchain network 200 verifies the digital certificate and the digital signature carried in the transaction, and after both are successfully verified, confirms whether the service agent 600 has a transaction right according to the identity information of the service agent 600 carried in the transaction, and the transaction fails due to any verification result of the digital signature and the right verification. After the rights verification is successful, consensus node 210 signs its digital signature (e.g., by encrypting a digest of the transaction using the private key of node 210-1) and continues to broadcast in blockchain network 200.

After receiving the transaction successfully verified, the consensus node 210 in the blockchain network 200 fills the transaction into a new block and broadcasts the new block. When broadcasting a new block, the consensus node 210 in the block chain network 200 performs a consensus process on the new block, and if the consensus is successful, adds the new block to the tail of the block chain stored in the consensus node, updates the state database according to the transaction result, and executes the transaction in the new block: for the transaction of submitting and updating the historical competition information of the party to be participated in, updating the key value pair corresponding to the historical competition information of the party to be participated in the state database; and for the transaction of inquiring the electronic certificate data, inquiring the key value pair corresponding to the electronic certificate data from the state database, and returning a transaction result.

It can be understood that the type of data that the service agent can query/update in the blockchain network 200 can be implemented by restricting the authority of the transaction that the service agent can initiate, for example, when the service agent 500 has the authority to initiate the transaction of querying the game result, the service personnel of the service agent 500 can input a query request of the game result in the graphical interface 510-1 of the terminal 500-1, and generate the transaction for querying the game result by the event management platform 300, and broadcast the transaction to the blockchain network 200 to obtain the corresponding game result from the blockchain network 200;

when the business agent 600 has the right to initiate a transaction for querying the electronic voucher data, the business personnel of the business agent 600 can input an electronic voucher data query request in the graphical interface 610-2 of the terminal 600-2, generate a transaction for querying the electronic voucher data by the event management platform 300, and broadcast the transaction to the blockchain network 200 to obtain the corresponding electronic voucher data from the blockchain network 200.

As an example of a block chain, referring to fig. 2, fig. 2 is an optional structural schematic diagram of a block chain in a block chain network 200 according to an embodiment of the present invention, a header of each block may include hash values of all transactions in the block and also include hash values of all transactions in a previous block, a record of a newly generated transaction is filled in the block and is added to a tail of the block chain after being identified by nodes in the block chain network, so as to form a chain growth, and a chain structure based on hash values between blocks ensures tamper resistance and forgery prevention of transactions in the block.

An exemplary functional architecture of a blockchain network provided by the embodiment of the present invention is described below, referring to fig. 3, fig. 3 is a schematic diagram of an optional functional architecture of a blockchain network 200 provided by the embodiment of the present invention, where the blockchain network 200 includes an application layer 201, a consensus layer 202, a network layer 203, a data layer 204, and a resource layer 205, and functions of each layer are described below.

The resource layer 205 encapsulates computing, storage, and communication resources that implement each node 210 in the blockchain network 200, such as computing, storage, and communication resources in computers, servers/clusters, and clouds, abstracts and provides a uniform interface to the data layer 204 to shield the underlying hardware implementing the resource layer 205 from differences.

Computing resources include various forms of processors, such as Central Processing Units (CPUs), application Specific Integrated Circuits (ASICs), and Field-Programmable Gate arrays (FPGAs).

The storage resources include various types of storage media such as various volatile memories and nonvolatile memories. The nonvolatile Memory may be a Read Only Memory (ROM) or a Programmable Read-Only Memory (PROM). Volatile Memory can be Random Access Memory (RAM), which acts as external cache Memory.

The communication resources include various communication links for communication between various nodes 210 in the blockchain network 200, between the blockchain network 200 and the traffic body.

The computing resources and storage resources of the resource layer 205 may be mapped to various types of nodes 210 in the blockchain network 200, and the storage medium implementing the embodiment of the present invention stores executable instructions for implementing the information processing method based on the blockchain network of the embodiment of the present invention, and once the executable instructions deployed to the nodes are executed, the underlying resources (e.g., various types of processors) implementing the nodes will implement the deployment of various types of nodes 210 in the blockchain network 200 and execute the functions of various types of nodes, thereby implementing ledgers for transactions in business processes and various applications based on the ledgers.

By way of example, executable instructions may be written in any form of programming language, including compiled or interpreted languages, or declarative or procedural languages, in the form of software (including system programs and applications), software modules, scripts, plug-ins, and the like, and may be deployed in any form, including as a stand-alone program or as a module, component, or other unit suitable for use in a computing environment.

The data layer 204 encapsulates various data structures that implement the ledger, including blockchains implemented in files in a file system, state databases of the key-value type, and presence certificates (e.g., hash trees of transactions in blocks).

The network layer 203 encapsulates the functions of a Point-to-Point (P2P) network protocol, a data propagation mechanism and a data verification mechanism, an access authentication mechanism, and a service agent identity management.

The P2P network protocol implements communication between each node 210 in the blockchain network 200, the data propagation mechanism ensures propagation of transactions in the blockchain network 200, and the data verification mechanism is used for implementing reliability of data transmission between each node 210 based on a cryptographic method (such as a digital certificate, a digital signature, and a public/private key pair); the access authentication mechanism is used for authenticating the identity of the service subject added into the block chain network 200 according to an actual service scene, and endowing the service subject with the authority of accessing the block chain network 200 when the authentication is passed; the business entity identity management is used to store the identity of the business entity that is allowed to access blockchain network 200, as well as the permissions (e.g., the types of transactions that can be initiated).

The consensus layer 202 encapsulates the functions of the mechanism for the nodes 210 in the blockchain network 200 to agree on a block (i.e., a consensus mechanism), transaction management, and ledger management. The consensus mechanism comprises consensus algorithms such as POS, POW and DPOS, and the pluggable consensus algorithm is supported.

The transaction management is configured to verify a digital signature carried in the transaction received by the node 210, verify identity information of the service entity, and determine whether the node has an authority to perform the transaction according to the identity information (read related information from the identity management of the service entity); for the service agents authorized to access the blockchain network 200, the service agents all have digital certificates issued by the certificate authority, and the service agents use private keys in their own digital certificates to digitally sign submitted transactions, so as to declare their own legal identities.

Ledger administration is used to maintain blockchains and state databases. For the block with the consensus, adding the block to the tail of the block chain; executing a transaction in the identified block, updating the key-value pair in the state database when the transaction comprises an update operation; and when the transaction comprises a query operation, querying the key-value pair in the state database, and returning a query result to the client of the business body. Supporting query operations for multiple dimensions of a state database, comprising: querying the chunk based on the chunk sequence number (e.g., hash value of the transaction); inquiring the transaction according to the transaction serial number; inquiring account data of a business main body according to an account (serial number) of the business main body; and inquiring the block chain in the channel according to the channel name.

The application layer 201 encapsulates various services that the blockchain network 200 can implement, including tracing, crediting, and verifying transactions.

For example, as an example of a software module, the memory 302 may include the information processing apparatus 40 based on the blockchain network provided by the embodiment of the present invention, which may be software in the form of programs and plug-ins, and include a series of software modules, see fig. 4B, where fig. 4B is a schematic diagram of an optional component structure of the information processing apparatus 40 based on the blockchain network provided by the embodiment of the present invention, for example, the information processing apparatus 40 based on the blockchain network includes: the functions of the first storage unit 41, the second storage unit 42, the association unit 43, the first receiving unit 44, the querying unit 45 and the second receiving unit 46 are logical, and therefore, any combination or further splitting may be performed according to the functions implemented by the respective software modules. It should be noted that, with regard to the specific functions of each unit in the information processing apparatus 40 based on the blockchain network provided by the embodiment of the present invention shown in fig. 4B, the following description will be made.

The following describes implementation of the information processing method based on the blockchain network according to the embodiment of the present invention, with reference to an exemplary application and implementation of the blockchain network according to the embodiment of the present invention.

Referring to fig. 5, fig. 5 is an optional flowchart of the information processing method based on the blockchain network according to the embodiment of the present invention, and it can be understood from the foregoing that the event management platform implementing the information processing method based on the blockchain network according to the embodiment of the present invention may be deployed in an electronic device (for example, a user terminal or a server), and taking the case that the event management platform is deployed in the server as an example, the following will be described with reference to the steps shown in fig. 5.

In step 501, the party to be participated in the event management platform for registration service.

In some embodiments, the registering the to-be-participated party to the event management platform for registration service may be implemented as follows: the business personnel of the party to be participated in inputs a request of registration service through a graphical interface of a first terminal belonging to the party to be participated in so as to send the request of registration service to the event management platform, the event management platform performs authorization verification on the party to be participated in according to the request of registration service, and after the party to be participated in obtains authorization of the event management platform, the party to be participated in can log in the event management platform and perform corresponding registration service on the event management platform.

Here, the service person of the party to be participated in is used to indicate a contestant who requests to participate in an event held by the event holder, such as a marathon contest. The registration service can be understood as a service person of the party to be participated in registering the personal information of the user.

Referring to fig. 6, fig. 6 is an interface schematic diagram of registering user personal information by a service person of a to-be-participated party according to an embodiment of the present invention, where the user personal information of the to-be-participated party includes at least one of the following information: when the party to be participated in logs in the event management platform for the first time, the name, the identity card number, the mobile phone number, the physical examination report, the photo and the like of the party to be participated in can input relevant information through the personal information registration interface shown in figure 6, and after the information input is finished, the registration process on the event management platform can be finished by clicking an 'entry' button. It should be noted that, after the party to be participated in completes the corresponding registration service on the event management platform, the electronic certificate data corresponding to the personal information of the user is generated on the personal information registration interface. Referring to fig. 7, fig. 7 is an interface schematic diagram of an event report performed by a competitor according to an embodiment of the present invention, so that when the competitor logs in the event management platform again to perform the event report, the competitor only needs to fill in personal essential information, such as name and identification number, upload electronic certificate data, and click a "submit" button, thereby completing the process of the event report.

In step 502, the event management platform receives the personal information of the user uploaded by the first terminal corresponding to the party to be participated in, in response to the registration service of the party to be participated in.

In step 503, the event management platform stores the user profile information in the blockchain network.

In some embodiments, before performing step 502, the information processing method based on the blockchain network may further include: and requesting access authority for the blockchain network of the party to be participated in, and receiving a digital certificate distributed by the blockchain network for the party to be participated in, wherein the digital certificate is used for signing a corresponding digital signature aiming at personal information of a user to be sent so as to declare the identity information of the party to be participated in to the blockchain network.

Here, the participants themselves may generate a corresponding public-private key pair based on a key generation algorithm, where the public-private key pair includes a public key and a private key corresponding to the public key. The key generation algorithm includes a symmetric key generation algorithm and an asymmetric key generation algorithm. In order to improve the security of the key and to ensure the non-tamper-resistance of the digital signature, preferably, the key generation algorithm may be an asymmetric key generation algorithm.

Illustratively, the to-be-participated party sends the public key to the blockchain network through the event management platform, so that a node having an authentication function in the blockchain network, that is, a CA (Certificate Authority) node, allocates a digital Certificate including the public key to the to-be-participated party, where the digital Certificate carries a digital signature signed by the CA node for the public key and the identity information of the to-be-participated party, and the digital signature is obtained by encrypting, by the CA node, the private key of the CA node, the public key of the to-be-participated party, and the identity information of the to-be-participated party. When a party to be participated in sends user personal information of the party to be participated in to the blockchain network through the event management platform, the user personal information carries a digital certificate signed by a CA node and a digital signature aiming at the user personal information, and after the node in the blockchain network receives the user personal information of the party to be participated in, the digital certificate and the digital signature are sequentially verified so as to determine the identity of the party to be participated in which the user personal information is sent and the reliability of the user personal information. And after the verification is successful, storing the personal information of the user into the block chain network. When the verification fails, a rejection message (e.g., lack of rights) is returned to the event management platform, and then the event management platform returns the rejection message to the party to be participated.

It should be noted that only the public key of the digital certificate can be verified and displayed in the blockchain network, but the private key generally does not exist in the blockchain network, so as to ensure the security of the private key.

In the embodiment of the present invention, the event management platform is deployed independently from the blockchain network, that is, the event management platform is an entity existing independently from the blockchain network. Therefore, in order to implement event management by using the blockchain technology, participants in the event management process related to the embodiment of the present invention, such as a party to be participated in, an event host, and the like, need to obtain authorization of the event management platform before accessing to the blockchain network, otherwise, the participants in the event management process cannot access to the blockchain network without obtaining authorization of the event management platform.

In some embodiments, referring to fig. 8, fig. 8 is another optional flowchart of the information processing method based on the blockchain network according to the embodiment of the present invention, and based on fig. 5, the storing of the user personal information in the foregoing step 503 into the blockchain network may also be implemented by the following step 5031 and step 5032, which will be described below with reference to each step.

In step 5031, the event management platform performs hash processing on the personal information of the user to obtain a hash value corresponding to the personal information of the user.

In step 5032, the event management platform stores the hash value of the user's personal information in the blockchain network.

For example, the personal information of the user may only include a small amount of text information, for example, the text information includes a user name, an identification number, and the like, and the event management platform may directly store the text information of the user name, the identification number, and the like of the party to be participated in the blockchain network. Of course, when the text information included in the user personal information is large, for example, the text information includes detailed description information of the historical participating events, the hash value of the text information included in the user personal information may be determined, and the obtained hash value may be stored in the blockchain network, so as to reduce the volume of the blockchain.

In other embodiments, the event management platform may further store the user personal information in the blockchain network as follows: firstly, determining text information included in user personal information, and storing the text information into a block chain network; secondly, determining multimedia information contained in the personal information of the user, and performing hash processing on the multimedia information to obtain a hash value corresponding to the multimedia information; and finally, storing the hash value of the multimedia information into the block chain network.

For example, the user personal information may also include multimedia information, for example, the user personal information includes photograph information of the party to be participated in, a hash value corresponding to a photograph of the party to be participated in may be determined first, the obtained hash value of the photograph of the party to be participated in is stored into the blockchain network, and text information and multimedia information included in the user personal information are separately stored into the blockchain network, so as to reduce the volume of the blockchain.

In other embodiments, the event management platform may further store the user personal information in the blockchain network as follows: sending the user personal information to a block chain network so that a node of the block chain network generates a new block corresponding to the user personal information; when the nodes providing the consensus service in the nodes of the block chain network acquire the consensus on the new blocks, the new blocks are added to the tail part of the block chain for storing the personal information of the user by the block chain network.

Specifically, the event management platform initiates a data transaction request to the blockchain network, wherein the data transaction request carries the personal information of the user to be participated in the event and the version of the intelligent contract to be called; after receiving the data transaction request, the block chain network generates a new block corresponding to the personal information of the user, signature information corresponding to the personal information of the user is stored in the new block, and when a plurality of nodes providing consensus service in the block chain network achieve consensus on the personal information of the user and the corresponding signature information, the event management platform calls a corresponding intelligent contract according to the version of the intelligent contract to be called, and writes the personal information of the user and the corresponding signature information into the block chain network by executing the intelligent contract.

Here, after the event management platform initiates a data transaction request to the blockchain network, each node in the blockchain network broadcasts the data transaction request sent by the event management platform to the whole network, where the data transaction request can be broadcast to the whole network in a P2P manner, at this time, a plurality of nodes providing a consensus service in the blockchain network vote the user personal information and the corresponding signature information, and based on the consensus mechanism adopted by the blockchain network, when the plurality of nodes providing the consensus service agree with the transaction, for example, when the vote for voting reaches a set condition, the event management platform may invoke a corresponding intelligent contract according to the version of the intelligent contract to be invoked, and write the user personal information and the corresponding signature information into the blockchain network by executing the invoked intelligent contract. The blockchain network has the characteristics of being not tampered and not revocable, so that the personal information of the user of the party to be participated and the corresponding signature information are stored in the blockchain network, and the safety and the reliability of the data stored in the blockchain network can be guaranteed.

In step 504, the event management platform receives the historical competition information for the party to be participated, which is uploaded by the second terminal corresponding to the event host.

Here, the event host may obtain the historical competition information of the party to be participated from the field association organization or the marathon association organization through the event management platform, wherein the historical competition information includes at least one of the following information: names of events attended historically; historical contest performance (e.g., the time used historically to play in a particular marathon contest); and (5) historical competition ranking.

In step 505, the event management platform generates electronic voucher data corresponding to the party to be participated in based on the historical competition information, and stores the electronic voucher data in the blockchain network.

In some embodiments, before performing step 504, the method for processing information based on a blockchain network may further include: requesting access authority for a block chain network of an event host; and receiving a digital certificate distributed by the blockchain network for the event host, wherein the digital certificate is used for signing a corresponding digital signature aiming at the to-be-sent historical competition information so as to declare the identity information of the event host to the blockchain network. Of course, it is also possible to perform step 502 before it is performed, i.e. the event host applies for the right to access the blockchain network in advance.

In some embodiments, referring to fig. 9, fig. 9 is another alternative flow chart of the information processing method based on the blockchain network according to the embodiment of the present invention, based on fig. 8, the storing of the electronic certificate data in the above step 505 in the blockchain network may also be implemented by the following steps 5051 and 5052, which will be described below in conjunction with the steps.

In step 5051, the event management platform sends the electronic voucher data to the blockchain network so that the nodes of the blockchain network generate new blocks of corresponding electronic voucher data.

In step 5052, when a node providing the consensus service among the nodes of the blockchain network obtains consensus for a new block, the new block is added by the blockchain network to the end of the blockchain for storing the electronic voucher data.

Specifically, the event management platform initiates a data transaction request to the blockchain network, wherein the data transaction request carries electronic certificate data of a party to be participated in the event and the version of the intelligent contract to be called; after receiving the data transaction request, the block chain network generates a new block corresponding to the electronic certificate data, signature information corresponding to the electronic certificate data is stored in the new block, and when a plurality of nodes providing consensus service in the block chain network achieve consensus on the electronic certificate data and the corresponding signature information, the event management platform calls a corresponding intelligent contract according to the version of the intelligent contract to be called, and writes the electronic certificate data and the corresponding signature information into the block chain network by executing the intelligent contract. Therefore, the reliability of the historical competition information of the party to be participated, which is uploaded by the competition host, can be ensured through the consensus mechanism of the block chain network.

In step 506, the event management platform associates the user personal information with the electronic voucher data.

In the embodiment of the invention, the event management platform associates the serial number of the personal information of the user with the on-chain address of the electronic certificate data. Here, the on-chain address of the electronic certificate data is returned by the blockchain network, and the number of the personal information of the user is associated with the on-chain address of the electronic certificate data to complete registration. The on-chain address may be a hash of a transaction of the blockchain network storing the electronic credential data, the blockchain network generating a hash of the corresponding transaction each time the transaction is executed, the hash of the transaction may be a string consisting of 64-bit characters and has uniqueness. The number of the personal information of the user is the unique identification value of the party to be participated in, so as to distinguish different parties to be participated in.

In step 507, the second terminal corresponding to the event host sends a data query request to the event management platform.

In the embodiment of the invention, the data query request carries the electronic certificate data to be verified submitted by the party to be participated in. In particular, the electronic voucher data to be verified are submitted by the party to be entered into the competition to the event host via the first terminal belonging to the party to be entered into the competition when wanting to obtain a request for permission to participate in the competition.

In some embodiments, after receiving a data query request sent by a second terminal corresponding to an event host, the event management platform may further obtain violation information of a party to be participated who submits electronic certificate data to be verified from the blockchain network; and when the number of times of illegal behavior information exceeds the illegal number threshold value, executing limitation processing on the event participation request initiated by the party to be participated in the set time period.

The violation number threshold value can be preset according to actual needs, and the party to be participated in the competition process may possibly have violation behaviors. Specifically, when it is determined that the number of times of violation behavior information of the to-be-participated party exceeds the violation number threshold, the limitation processing is performed on the event participation request initiated by the violation to-be-participated party within the set time period, for example, a prohibition measure is implemented on the activity of the violation to-be-participated party within a certain time period, so that the fairness and justice of the event can be effectively guaranteed.

In step 508, the event management platform queries the blockchain network based on the performed associations in response to the data query request.

In some embodiments, before performing step 508, the information processing method based on the blockchain network may further include: verifying the digital signature carried in the data query request and the identity information of the event host initiating the data query request; and determining whether the event host has the authority for initiating the data query request according to the identity information of the event host.

Specifically, the event management platform acquires a public key corresponding to the event host, verifies the identity information of the event host based on the acquired public key, and determines that the event host has the authority to initiate the data query request when the identity information is verified. Here, for verifying the identity information of the event host based on the obtained public key, the following may be implemented: decrypting the identity information of the event host by using the public key to obtain a corresponding decryption result, comparing the obtained decryption result with the recalculated abstract, and determining that the identity information of the event host passes verification if the decryption result is matched with the abstract; and if the decryption result does not match the abstract, determining that the identity information verification of the event host is not passed.

In some embodiments, referring to fig. 10, fig. 10 is another optional flowchart of the information processing method based on a blockchain network according to an embodiment of the present invention, and based on fig. 9, the querying for the blockchain network based on the association performed in the step 508 described above may also be implemented by the following step 5081 and step 5082, which will be described below with reference to each step.

In step 5081, the event management platform queries the linked address of the associated electronic voucher data according to the number of the personal information of the user of the party to be participated who submits the electronic voucher data to be verified in response to the data query request for the electronic voucher data to be verified.

In step 5082, the event management platform queries the corresponding electronic voucher data to be verified in the blockchain network according to the queried on-chain address.

That is, the event management platform queries whether the electronic voucher data to be verified exists in the blockchain network according to the queried on-chain address, and verifies the validity of the on-chain address of the associated electronic voucher data to form a verification result of a transaction corresponding to a data query request initiated by an event host, wherein the verification result can be used as a qualification certificate for the participating party to obtain the participating event.

In some embodiments, when the transaction corresponding to the data query request is successfully verified, the event management platform feeds back the successful transaction verification result to the blockchain network, and at this time, after receiving the successful transaction verification, the node in the blockchain network with the sorting function fills the successful transaction verification into a new block and broadcasts the successful transaction verification to the node providing the consensus service in the blockchain network; the node providing the consensus service in the blockchain network performs the consensus process on the new block to reach an agreement, the node providing the ledger function adds the new block to the tail of the blockchain, and executes the transaction in the new block: and for the query transaction of the electronic certificate data to be verified submitted by the party to be participated in the query, querying the key value pair corresponding to the electronic certificate data shown by the party to be participated in the state database, and returning the query result.

In step 509, the blockchain network returns the query result for the electronic voucher data to be verified to the event management platform.

In order to enable the event host to more intuitively perceive the query result, the embodiment of the invention can visually display the query result received by the event management platform. In some embodiments, referring to fig. 11, fig. 11 is another optional flowchart of the information processing method based on the blockchain network according to the embodiment of the present invention, and based on fig. 5, after step 509, steps 510 to 512 may also be performed. The following will explain the steps.

In step 510, the event management platform sends the query result to the second terminal for presentation, so that the second terminal determines whether the party to be participated in has a participation qualification based on the query result, and generates a corresponding competition qualification auditing result.

In step 511, the event management platform receives the competition qualification audit result sent by the second terminal,

in step 512, the event management platform stores the competition qualification audit result into the blockchain network.

In some examples, when the query result presented by the client of the second terminal belonging to the event host is queried, the event host determines that the party to be participated in the event has a qualification for participating in the event according to the query result, and at this time, the event host passes the examination of the entry of the party to be participated in the event, see fig. 12, where fig. 12 is an interface diagram of the examination of the entry of the party to be participated in the event host according to the embodiment of the present invention, and the examination result of the qualification for participating in the event can be submitted by clicking the "pass" button; otherwise, when the query result presented by the client of the second terminal belonging to the event host is not queried, the event host determines that the party to be participated in does not have the qualification for participating in the event according to the query result, and at this time, the event host fails to audit the registration of the party to be participated in the event, and submits the auditing result of the qualification for participating in the event by clicking the 'reject' button in fig. 12.

In some embodiments, the information processing method based on the blockchain network may further include:

receiving data synchronization requests of other event hosts accessed to the blockchain network; analyzing the data synchronization request to obtain the identity information of the corresponding other event host carried in the data synchronization request; responding to the data synchronization request, and verifying the transaction authority of the other event host based on the identity information of the other event host; and when the transaction authority of the other event host is verified, controlling the data synchronization between the current event host and the other event host.

Here, the current event host is used for representing the event host corresponding to the second terminal sending the data query request; the other event host is an event host located in the alliance blockchain of the blockchain network except the current event host.

For example, because other event hosts in the blockchain network cannot acquire the user information uploaded by the current event host, such as the historical competition information of the party to be participated in, when the other event hosts in the blockchain network expect to acquire the corresponding user information, the corresponding data synchronization request needs to be initiated, and the event management platform can verify the authority of the other event hosts according to the received data synchronization request; when the authority of other event hosts passes the verification, the data synchronization between the current event host and other event hosts is controlled (for example, the data synchronization can be performed in a mode that the other event hosts and the current event host achieve consensus), the integrity of the transmission of the user information between different event hosts is ensured, and the synchronous sharing of the information of the parties to participate in the event is realized.

Compared with the scheme of realizing information management by an event management system in an event host in the related technology, the technical scheme provided by the embodiment of the invention is adopted, and the information of the party to be participated in, such as the personal information of a user and the electronic certificate data generated based on the historical competition information, is stored in the blockchain network by introducing the blockchain technology, so that the security of the information of the party to be participated in can be ensured by utilizing the characteristics of non-tampering and non-revocable property of the blockchain network, and the information leakage of the party to be participated in can be avoided; meanwhile, when the party to be participated in wants to obtain the permission request of the event participation, the event management platform carries out data query on the information to be verified submitted by the party to be participated in based on the blockchain network, so that the efficiency and the reliability of querying the information of the party to be participated in can be effectively improved, and the truth and the validity of the information of the party to be participated in are ensured.

In the following, an exemplary application of the embodiments of the present invention in a practical application scenario will be described.

Before exemplary description of an application scenario of an embodiment of the present invention, a related art event management scheme is described. In the related art, generally, an event management system inside the operator manages information of contestants, such as personal contest scores of parameter players and information in the process of the contest, but cannot effectively share and check the information of the contestants, so that the situation that the contestants forge historical contest scores during registration occurs, and a part of the contestants possibly violate many times in the process of the contest is caused, while an existing event management system inside the operator cannot effectively manage the violation of the contestants.

In order to solve at least the above technical problems of the related art, embodiments of the present invention provide an information processing method, an information processing apparatus, an electronic device, and a storage medium based on a blockchain network, which establish a transparent, reliable, unified information management platform, that is, an event management platform, to uniformly manage multiple participants, store historical competition scores and user personal information of each contestant through the blockchain network, ensure the security of the information of the contestants, share the information of the contestants to other event host accessing a league chain through the blockchain network, and the event host can verify the information of the named contestants in real time through the blockchain network, thereby improving the efficiency and reliability of querying the information of the named contestants, and performing corresponding punishment on the illegal contestants.

Referring to fig. 13, fig. 13 is a schematic diagram illustrating an optional schematic structure of an event management method based on a blockchain network according to an embodiment of the present invention, where participants involved in an event management process, such as contestants and event staff of an event host, may perform entry of a marathon event and performance query of the marathon event through a marathon event management platform by the contestants, and may perform check or audit of information of the contestants through the marathon event management platform by the event staff of the event host. For example, the contestants may log in to the marathon event registration system to share their own information, such as user personal information or historical event information, with the marathon event management platform, and the event host, track, and marathon associations on the marathon event management platform may obtain the contestant's information. The marathon event management platform links the hash value of the information recorded by the participant by calling a corresponding intelligent contract, such as an event management contract, that is, the hash value of the information uploaded to the marathon event management platform by the participant is stored in a blockchain network, wherein each node in the blockchain network is in a distributed account book storage mode, and the information stored in the blockchain network cannot be tampered. The event staff of the event host can verify the information shown by the contestants before the event through the blockchain network, so as to improve the efficiency and the credibility of the information verification of the contestants.

An exemplary application of the embodiments of the present invention in a practical application scenario will be described next with reference to fig. 13. The following describes an implementation of the information processing method based on the blockchain network according to the embodiment of the present invention in an actual application scenario, taking an application scenario in which a competitor wants to obtain an event entry permission request of the event host a.

Referring to fig. 14, fig. 14 is another optional flowchart of the information processing method based on a blockchain network according to the embodiment of the present invention, and the following description will be made with reference to the steps shown in fig. 14. For details which are not exhaustive in the following description of the implementation of the steps, reference is made to the above for an understanding.

In step 1401, the terminal corresponding to the event host a or the event host B uploads the historical competition information of the competitors to the marathon competition management platform.

In step 1402, the marathon event management platform generates corresponding electronic voucher data based on the historical competition information, and stores the electronic voucher data in the blockchain network.

In step 1403, the contestant logs in to the marathon event management platform to register personal information.

In step 1404, after the marathon event management platform acquires the user personal information of the contestant, it stores the user personal information of the contestant in the blockchain network.

In step 1405, the contestant, when attempting to obtain an event entry approval request from the event host A, presents the electronic voucher he or she owns to the event host A.

In step 1406, the event host a, after obtaining the electronic voucher presented by the contestant, initiates a data query request to the marathon event management platform.

In step 1407, the marathon management platform queries the blockchain network in response to the data query request.

In step 1408, after the blockchain network checks the electronic voucher shown by the contestant, the query result is returned to the marathon event management platform.

In step 1409, the marathon event management platform sends the query result to the event host a for the event host a to determine whether the contestant qualifies for a contest.

In step 1410, when the contestant qualifies for a contest, the contestant completes the corresponding marathon event by an entry audit of the marathon event.

In step 1411, after the contestants complete the corresponding marathon event, the event host a obtains the contest performance of the contestants, and uploads the current contest performance of the contestants to the marathon event management platform.

In step 1412, the marathon event management platform stores the current competition score into the blockchain network to update the original electronic voucher data.

In step 1413, the blockchain network returns the updated electronic voucher data to the event host a.

In step 1414, the event host A issues the updated electronic voucher data to the contestant.

According to the information processing method based on the blockchain network, provided by the embodiment of the invention, the personal information and the historical scores of the contestants are stored in the blockchain network based on the blockchain technology, so that the safety of the information of the contestants is ensured, the sharing of the personal information and the historical scores of the contestants can be realized, and the competition sponsor can effectively check and report the authenticity of the personal information and the historical scores of the contestants, thereby reducing the checking cost and improving the checking efficiency; meanwhile, the block chain network can also record the illegal behaviors of the contestants in the contesting process, implement a competition forbidding measure on the activities of the contestants in a certain time period, and effectively ensure the fairness and the justice of the events.

Next, a software implementation of the information processing apparatus 40 based on the blockchain network according to the embodiment of the present invention will be described. Taking the software module included in the memory 302 of the electronic device 30 as an example, the details that are not described in the following description of the function of the module can be understood by referring to the above description.
