Detailed Description

To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

Hereinafter, terms related to the present application are explained.

Block chain (English: blockchain): the method is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of data blocks associated by using cryptography, each data block contains information of a batch of network transactions, and the information is used for verifying the validity (anti-counterfeiting) of the information and generating the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after the effective request is identified in a consensus, and for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the encrypted service information to a shared account (network communication) completely and consistently, and records and stores the encrypted service information; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.

The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use.

Consensus mechanism (English: consensus mechanism): the block chain system is a mathematical algorithm for establishing trust and obtaining rights and interests among different nodes. In the block chain system, the verification and confirmation of the transaction can be completed in a short time through the voting of the special node devices, and if a plurality of node devices with irrelevant benefits can achieve the consensus, all the node devices in the system can also achieve the consensus.

Smart contract (english): is a computer protocol intended to propagate, validate or execute contracts in an informational manner. Each node device in the blockchain system can automatically execute a contract program according to a specific condition, can operate data stored in the chain, and is an important way for a user to interact with the blockchain and realize business logic by using the blockchain. The goal of smart contracts is to provide a secure method over traditional contracts and to reduce other transaction costs associated with the contracts, which allows for trusted transactions that are traceable and irreversible without third parties. The intelligent contracts are triggered by transactions, and can read, write and calculate transaction data on a blockchain, so that the operation of various business applications is supported. The computerized program capable of automatically executing contract clauses identifies and judges data information obtained from the outside, and immediately triggers the system to automatically execute corresponding contract clauses when the conditions set by the central node and the alliance node are met, so as to complete the transaction and the transfer of the universal virtual resources/mechanism virtual resources in the embodiment of the application. The intelligent contract in the embodiment of the application is divided into a universal part and a customized part. The universal part supports basic functions of identity authentication, transaction, virtual resource transfer and the like. The customized part is used for coping with the differentiated application scenario of the third node device, and the third node device can realize special functions by configuring an independent intelligent contract.

Public key (English) and private key (English): is a key pair (i.e., a public key and a private key) obtained by an algorithm, the public key being a public part of the key pair, and the private key being a non-public part. Public keys are typically used to encrypt data, verify digital signatures, and the like. By means of this algorithm it is ensured that the resulting key pair is unique, and that when using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt it, e.g. if the data is encrypted with the public key, the private key must be used to decrypt it, and if the data is encrypted with the private key, the public key must be used to decrypt it, otherwise the decryption will not succeed.

The present embodiment provides a blockchain system 100 implemented based on the above-mentioned blockchain technique, and a system architecture of the blockchain system is described below. Referring to fig. 1, the blockchain system may include a plurality of node apparatuses 101, and may further include a client. Node device 101 may be any form of computing device in a network, such as a server, a host, a user terminal, etc. The node apparatus 101 and the node apparatus 101 can share data therebetween. Among them, the node devices 101 may establish a P2P network based on a Peer-To-Peer (P2P) protocol. The P2P Protocol is an application layer Protocol that runs on top of the Transmission Control Protocol (TCP) Protocol.

Each node apparatus 101 may receive input information during normal operation, and maintain shared data in the blockchain system based on the received input information. In order to ensure information intercommunication in the blockchain system, information connection can exist between each node device in the blockchain system, and information transmission can be carried out between the node devices through the information connection. For example, when any node device in the blockchain system receives input information, other node devices in the blockchain system acquire the input information according to a consensus algorithm, and store the input information as data in shared data, so that the data stored in all the node devices in the blockchain system are consistent.

Each node device in the blockchain system has a node device identifier corresponding thereto, and each node device in the blockchain system can store node device identifiers of other node devices in the blockchain system, so that the generated block is broadcast to other node devices in the blockchain system according to the node device identifiers of the other node devices in the subsequent process. Each node device may maintain a node device identifier list as shown in table 1 below, and store the node device name and the node device identifier in the node device identifier list correspondingly. The node device identifier may be an IP (Internet Protocol) address and any other information that can be used to identify the node device, and table 1 only illustrates the IP address as an example.

TABLE 1

Node device name	Node device identification
		Node device 1	117.114.151.174
Node device 2	117.116.189.145
		…	…
Node device N	119.123.789.258

Each node device in the blockchain system stores one identical blockchain. The block chain is composed of a plurality of blocks, referring to fig. 2, the block chain is composed of a plurality of blocks, the starting block includes a block header and a block main body, the block header stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain is associated with the block data stored in the parent block, and the safety of the input information in the block is ensured.

When each block in the block chain is generated, referring to fig. 3, when the node device where the block chain is located receives input information, the input information is verified, after the verification is completed, the input information is stored in the memory pool, and the hash tree for recording the input information is updated; and then, updating the updating time stamp to the time when the input information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

Therefore, when the random number meeting the formula is obtained through calculation, the information can be correspondingly stored, and the block head and the block main body are generated to obtain the current block. And then, the node equipment where the block chain is located respectively sends the newly generated blocks to other node equipment in the block chain system where the newly generated blocks are located according to the node equipment identifications of the other node equipment in the block chain system, the newly generated blocks are verified by the other node equipment, and the newly generated blocks are added to the block chain stored by the newly generated blocks after the verification is completed.

The functional architecture of the node apparatus 101 in the blockchain system is described below.

For example, the services implemented by the application include:

2.1) wallet, for providing the function of transaction of electronic money, including initiating transaction (i.e. sending the transaction record of current transaction to other node devices in the blockchain system, after the other node devices are successfully verified, writing the record data of transaction into the temporary blocks of the blockchain as the response of affirming that the transaction is valid; of course, the wallet also supports the querying of the electronic money remaining in the electronic money address.

And 2.2) the shared account book is used for providing functions of operations such as storage, query and modification of account data, sending the recorded data of the operations on the account data to other node equipment in the block chain system, writing the recorded data into a temporary block as a response for acknowledging that the account data is valid after the other node equipment verifies that the operation is valid, and sending confirmation to the node equipment initiating the operation.

2.3) Intelligent contracts, computerized agreements, which can enforce the terms of a contract, implemented by codes deployed on a shared ledger for execution when certain conditions are met, for completing automated transactions according to actual business requirement codes, such as querying the logistics status of goods purchased by a buyer, transferring the buyer's electronic money to the merchant's address after the buyer signs for the goods; of course, smart contracts are not limited to executing contracts for trading, but may also execute contracts that process received information.

3) And the Block chain comprises a series of blocks (blocks) which are mutually connected according to the generated chronological order, new blocks cannot be removed once being added into the Block chain, and the blocks record the record data submitted by the node equipment in the Block chain system.

The embodiment of the application can be applied to a federation chain, and each node device in the federation chain may belong to each related enterprise, for example, as shown in fig. 5, the federation chain may include node devices belonging to a government agency, a regulatory agency, an enterprise, a credit platform, and a judicial arbitration agency, respectively, so as to supervise the service of the credit platform. That is, alliance chain nodes can be deployed on servers corresponding to the above-mentioned organizations, an individual can perform a service through the block chain nodes corresponding to the unified platform, when service data occurs, data synchronization can be performed in the alliance chain based on the block chain characteristics, each node device can store a required metadata, data consistency is guaranteed, decentralized distributed storage is provided, it is not only guaranteed that all related service parties follow the same permission mechanism, but also mutual communication and data sharing among the node devices in the alliance chain can be realized, and the node devices can all participate in the service processing process. Based on the architecture, a regulatory body can record, supervise and audit related processing flows in a federation chain, for example, the regulatory body can supervise an agency exit flow related to the embodiment of the present application.

It should be noted that the above-mentioned service processing procedures, for example, the processing procedure for the quit service request, and the like, may be implemented based on an intelligent contract deployed on the blockchain, where the intelligent contract may include an intelligent contract for processing data processing, data storage, and uplink service of the voting process of the voter, may also include an intelligent contract for performing judicial evidence preservation to implement evidence preservation, and may also include an intelligent contract for performing voting verification to verify whether the voting information in the system and the data stored on the blockchain are consistent.

The management of the intelligent contract, such as deployment, release, and update, may be triggered by a user through a blockchain management platform running on a node device in a federation chain, as shown in fig. 6, the blockchain management platform may be used to implement functions such as data overview, management of the node device, monitoring of a running state of the node device, management of a private key, and system management, in addition to the contract management function, and the blockchain management platform may visually represent information such as a node in the blockchain system, a deployed intelligent contract, an existing block in the chain, and a transaction quantity stored in the chain, and may also provide a trend graph display of a key monitoring index, and the like, where the form shown in fig. 6 is merely an example, and the embodiment of the present application does not limit a specific display form thereof.

It should be noted that, the user can register the identity information of the individual or the enterprise at the business front end of the credit platform and perfect the individual account information. The user may be a lending user or a lending user of a credit service. Taking a lending user as an example, the lending user can submit identity certification information such as photos on the front and back sides of an identity card when applying for resource lending, the credit platform can perform asset clearing according to the identity of the lending user and includes detailed information such as a fund returning channel, and finally the lending user confirms and submits the information to the credit platform which stores the information to a block chain of the block chain system. Through the storage of the identity-related information and other information, the data can be executed based on the data recorded in the system in any subsequent business process, the technical advantages of tamper resistance and decentralization of the block chain technology are utilized, and persistent, high-reliability and high-safety data recording is performed.

It should be noted that, in a case that the block chain is a federation chain, each node device in the federation chain may be configured with the same block chain, and each node device may also be configured with its own private chain, that is, a block chain only used for the node device to perform data storage, query, and other processing.

The block chain system according to the embodiment of the present application may include a first node device and a second node device. The first node device may be a target organization, that is, a node device corresponding to a credit platform, or a node device corresponding to a regulatory agency, and the second node device may be a node device for providing an electronic notarization service, or a node device of a judicial arbitration organization. Based on the architecture of the block chain system, refer to fig. 7, where fig. 7 is an interaction flowchart of a voting processing method based on a block chain according to an embodiment of the present application.

700. And the terminal displays a target voting page, wherein the target voting page is a page for voting aiming at the service quitting request initiated by the target mechanism.

For the block chain system, any node device may operate the service platform, for example, a target organization may operate the service platform through its own corresponding node device, or may operate the service platform through other node devices having a supervision authority on the service of the target organization in the federation chain. In this embodiment of the present application, the target mechanism may initiate an exit vote on the service platform, and the service platform may generate a target voting page based on the exit vote, so that the terminal can display the target voting page by accessing the service platform, thereby participating in the vote. The access of the terminal to the service platform can be realized by running a voting client of the service platform or accessing a portal website of the service platform, and the like, and the embodiment of the application does not limit the specific way of accessing the target voting page.

The goal voting page displayed on the terminal may include project information of the goal voting project, voting options, and voting submission options. The item information of the target voting item can comprise an exit reason, an exit time, a processing strategy for the relevant user after the exit, and the like; the voting option refers to an option whether to approve the voted item, for example, for quitting voting, the voting option may include quitting and disapproving quitting; the voting submission option is used for responding to a submission operation of the user, generating voting information corresponding to the voting option selected by the user, and submitting the voting information to the service platform. Optionally, in order to ensure the right of knowledge of the lending user, the service platform may further provide a loan resource confirmation page for displaying the resource loan information between the lending user and the target institution, and when the lending user confirms the accuracy of the resource loan information on the loan resource confirmation page, the lending user determines the voting option selected by the lending user. For example, fig. 8 is a schematic diagram of a loan resource confirmation page according to an embodiment of the present application, where the schematic diagram may show that the amount of outstanding funds lent by the lender on the lending platform is 10000RMB, and if the confirmation is consistent, the user may check that the loan is submitted by clicking the confirmation option 800. It should be noted that the loan resource confirmation page may be provided with a time limit, for example, during the voting notice public period, so as to avoid wasting platform resources.

It should be noted that the user can log in the service platform based on real-name identity authentication and other manners, so as to perform voting based on the target voting page, thereby avoiding the user performing voting at will, ensuring that the identity of the user who participates in the voting is legal, and ensuring the validity of the voting.

In one possible implementation, the voting process may be audited by other mechanisms to inform and urge the lender to vote. Correspondingly, the method may further include: in the voting period of the target voting, the node equipment for auditing and monitoring acquires the identity of the lending user of the target mechanism, screens out the identity of the user who does not participate in the voting in the identity of the lending user according to the identity of the voted user of the target voting, and pushes voting reminding information to the user based on the identity of the user who does not participate in the voting so as to remind the user to participate in the voting period and avoid missing the voting period.

701. And the first node equipment responds to the voting submission operation aiming at the target voting page on the terminal and acquires the voting information of the voting submission operation.

After detecting the vote submission operation of the user on the target vote page, the terminal may submit the vote submission operation to any node device in the blockchain system, where the submission may be first submitted to the service platform and then sent to any node device in the blockchain system by the service platform, or may be directly sent to any node device in the blockchain system through communication with the blockchain system.

702. The first node device obtains the biometric characteristic of the implementer of the vote submission operation.

It should be noted that the biometric feature can uniquely identify the feature of a person, and therefore, the identity of the performer can be determined by obtaining the biometric feature of the performer to determine whether the performer is a person who has the right to participate in the voting. In some possible implementations, the biometric feature may include a plurality of different features, such as a human voice feature and a five-sense feature, for which the biometric feature of the person performing the vote submission operation includes at least one of: recording the voice of the executor through sound acquisition equipment to obtain the voice data of the executor, and extracting the voice feature of the executor from the voice data; and acquiring the face of the executive person through an image acquisition device to obtain a face image of the executive person, and extracting the five-sense organ characteristics of the executive person from the face image.

703. And the first node equipment acquires the identity matched with the biological characteristics from the block chain of the block chain system according to the biological characteristics of the executor.

For the blockchain system, the biometric characteristics and the corresponding identification of the user registered on the credit platform can be stored in a blockchain storage mode. After acquiring the biological features of the executor, the first node device may determine, according to the acquired biological features, whether a biological feature matching the acquired biological features exists in the stored biological features on the block chain, and if so, may acquire an identity corresponding to the stored biological features, and may use the acquired identity to represent identity information in the voting process; if not, the executive is not the registered user on the credit platform, and the subsequent steps are not executed.

The above steps 702 and 703 are processes of performing identity recognition based on the biometric features of the executor performing the voting submission operation to obtain the identity of the executor. Through the acquisition process of the identity identification, the identity of the voting participants can be guaranteed to be legal, the condition that others falsify and pretend in the voting process is prevented, and the public credibility of the voting result can be ensured. Under the condition of acquiring the identity, the subsequent uplink storage process can be carried out only based on the identity without carrying out uplink storage on all sensitive information of the user, so that the identity of the voting participants is guaranteed to be legal, and the privacy of the voting participants can be protected.

704. The first node device obtains the resource loan information of the identity from the blockchain system according to the identity.

For the participating voting users, the identities of the participating voting users should belong to the lenders of the target structure, and therefore, the resource lending information of the participating voting users, that is, the creditor information, such as the loan amount, the outstanding balance amount, and the like, should be stored in the block chain system, and the first node device may perform a query in the block chain system according to the identities to obtain the blocks including the identities, and obtain the resource lending information of the identities from the obtained blocks. Because the resource lending information of the lender is stored in the block chain, the data reliability of the lender can be ensured.

705. The first node device performs voice interaction with the executor based on the resource lending information of the identity, and if it is determined through the voice interaction that the resource lending information matches, step 706 is performed.

After the first node device obtains the resource lending information of the identity, the first node device can trigger voice interaction between the robot and the executor to verify the identity of the executor, so that the accuracy of the identity of the voting participant is further ensured.

In a possible implementation manner, the first node device sends the resource lending information and the phone number of the identity to the intelligent voice interaction robot, the intelligent voice interaction robot generates voice information based on the resource lending information of the identity, initiates a voice call based on the phone number, after the voice call is connected, plays the voice information for the user, and provides a way for the user to confirm that the voice information is correct, for example, if the amount is correct, confirm please press 1, and the like, if a confirmation instruction of the user for the played content is received, it is determined that the resource lending information is consistent, and the identity of the voting executor is correct. Of course, the above process is only an example of voice interaction, and the embodiment of the present application may also apply other ways to perform identity verification to achieve the purpose of authentication.

706. The first node device compares the digital certificate carried by the voting information with the digital certificate of the identity stored in the blockchain system, and if the digital certificates are the same, step 707 is executed.

The first node device can also provide verification of the digital certificate, for voting information, when a voting user executes voting operation, the digital certificate can be provided through importing the digital certificate or importing a private key, and the like, furthermore, the voting information received by the first node device can carry the imported digital certificate or the digital certificate obtained based on the imported private key, the digital certificate of the identity is obtained from the block chain based on the identity for comparison, and if the digital certificates are the same, the identity of the voting user can be confirmed.

In the above steps 702 to 706, online biometric identification technology, intelligent voice interaction robot and digital certificate authentication are introduced for identity verification. On one hand, the identity of the lender is confirmed by using a face recognition and digital certificate authentication mode, so that the condition that others falsify in the voting process can be prevented, all sensitive information of the voter is prevented from being linked up, and the public credibility of the voting result is ensured while the privacy of the user is protected. On the other hand, the intelligent voice interaction robot is used for voice interaction with the lender to confirm the creditor information, so that the counterfeit situation of other people is further prevented, and the public credibility and the validity of voting are ensured.

Optionally, the identities of the participating voting users may also be uplinked. For example, the identity of the voting users is stored in the form of blocks in the block chain, and certainly, a voter identity chain may be configured in the block chain system, and is dedicated to record the identities of the voting users, and the identities of the voting users and the voting items are stored in the voter identity chain in the form of blocks. In an alternative, the voice interaction process may also be recorded to obtain a voice recording, and the voice recording may be uplinked. For example, the voice records of the voting users are stored in the form of blocks in the block chain, and of course, a voting voice record chain may be configured in the block chain system, and is dedicated to record the voice records of the voting users, and the voice records of the voting users and the voting items are stored in the voting voice record chain in the form of blocks. The storage can ensure the safety and reliability of the voting related information through the characteristics of high difficulty in information tampering on the block chain and traceability.

It should be noted that, in the above steps 702 to 706, multiple authentications based on the intelligent voice interaction robot and the digital certificate authentication may also be optional steps, and in some possible implementations, the optional steps may be selectively combined with the steps 702 and 703 according to actual situations to enhance the verification accuracy, and the combination of which verification manner is specifically adopted is not limited in the embodiment of the present application.

707. And the first node equipment acquires the electronic notarization information of the voting information through interaction with the second node equipment in the block chain system.

708. In response to the voting information, the identity identifier and the electronic notarization information passing through the block chain system in a consensus manner, the first node device stores a target block on a block chain of the block chain system, the target block chain is used for storing relevant data of the voting activity, and the target block is used for storing the voting information, the identity identifier and the corresponding electronic notarization information of the user account.

For the above consensus process, reference may be made to the process described in the foregoing embodiment, and in the blockchain system, the consensus process may be initiated by any node device, so as to generate a target block based on the data passed by the consensus, so as to uplink store the voting information, the identity of the voting participant user, and the electronic notarization information obtained by notarization. Based on the advantages of tamper resistance and decentralization of the block chain technology, the relevant voting information is recorded, and each vote can be recorded and cannot be tampered under the condition that the privacy of a user is guaranteed. Meanwhile, each vote is participated in chain official deposit evidence by an authority, so that evidence preservation of the voting result can be ensured from a legal perspective, and finally, judicial validity and truthfulness and credibility of the voting data in the whole process are ensured.

In addition, when the voting result is calculated based on the voting information, the specific calculation mode can be performed according to the preset calculation rule of the voting items, and different voting items can correspond to different calculation rules. For example, refer to the ninth item of rules (trial) for good quit of the unified voting system by the network lending institution: the online credit institution clearing group calculates the voting weight of the amount of the unpaid repayment sum of the lender and the total amount of the unpaid repayment sum of the online credit institution based on the voting notice release date, correspondingly, the preset calculation rule can set the voting weight based on the amount of the unpaid repayment sum of the participated voting users and the total amount of the unpaid repayment sum of the online credit institution, and the voting result is obtained based on the weighted summation of the voting information of all the participated voting users. In brief, if the sum of the outstanding repayment amount of a participating voting user is 10 ten thousand and the sum of the outstanding repayment amount of the online credit institution is 100 ten thousand, the voting weight of the participating voting user may be 10 ten thousand/100 ten thousand to 0.1, and the influence of the voting information in the final voting result may reach 0.1.

After obtaining the voting result based on the voting information, the first node device obtains the voting result through interaction with the second node device to perform notarization so as to obtain electronic notarization information of the voting result, and returns the electronic notarization information to the first node device, the first node device stores the electronic notarization information of the voting result based on the intelligent contract, and the services such as verification and the like can be performed based on the stored electronic notarization information in the later period. In a possible implementation manner, the first node device may further carry electronic notarization information of voting information obtained through evidence storage when sending the voting result to the second node device, and after receiving the voting result and the electronic notarization information of the voting information, the second node device may further perform verification based on the electronic notarization information of the voting information, and provide an electronic notarization service of the voting result after the verification is passed. Certainly, the second node device may also perform electronic notarization directly based on the received voting result and the electronic notarization information of the voting information, and return the voting result and the electronic notarization information of the voting information to the second node device, thereby implementing the electronic notarization.

In the blockchain system according to the embodiment of the present application, in order to ensure reliability of uplink data, uplink permission may be issued only to some node devices in the blockchain system, and some other node devices may only have permission to query data. That is, the blockchain system further includes a third node device, and the third node device has the inquiry permission of the blockchain and does not have the data uplink permission to the blockchain. For example, for the node device corresponding to the credit agency, the data uplink authority and the query authority may be issued for the node device, and for the node device corresponding to the supervision agency, the data query authority may be issued for the node device.

The block chain system of the embodiment of the application can also provide a voting verification service, and anyone can verify whether the data of the voting system is consistent with the data stored on the block chain through the service, so that the whole voting process is supervised from the perspective of everyone, and the public credibility of the voting result is enhanced. That is, the blockchain system further includes a fourth node device, where the fourth node device is configured to, in response to a verification request for any voting item, verify a voting result of the voting item according to the voting information stored in the blockchain, and output the verification result.
