Wherein, management and control not only includes reasonable planning, but also includes accurate reimbursement. And if the management system encounters chaotic asset reimbursement, the management system cannot well complete the asset management work of the enterprise, so that reasonable planning and accurate reimbursement are an indispensable part for better completing the asset management work of the enterprise.
The reimbursement part in the traditional asset management work sends reimbursement requests and related proving materials to corresponding staff members through staff members with reimbursement requirements, and the staff members finish reimbursement work according to the reimbursement requests and related proving materials, however, the possibility that the reimbursement materials or the reimbursement requests are tampered or forged exists in the process, the authenticity of the final reimbursement result is difficult to effectively guarantee, and the reimbursement work in the asset management is risky.
The asset management work is deployed into the blockchain at the present stage, so that the situation that the evidence material is tampered or forged is reduced, and the risk of the asset management work is indirectly reduced. That is, personnel with reimbursement requirements store related evidence directly in the blockchain, so that the possibility of tampering the evidence is reduced by intervening other personnel; and then sending the reimbursement request to the corresponding asset management end, so that the asset management end actively searches related evidence data from the blockchain to finish reimbursement work in asset management, thereby achieving the aim.
However, once the number of reimbursement requests is increased, the existing method can lead the asset management end to face a plurality of reimbursement requests at the same time, so that on one hand, the pressure of the request is intangibly given to the asset management end, the probability of collapse of the asset management end is increased, and the aim of reducing the risk of asset management work cannot be effectively achieved; on the other hand, the pressure of the asset management end for processing the reimbursement work is also given, the probability of errors in the process of processing the asset management end is increased, and the aim of reducing the risk of the asset management work cannot be effectively achieved.

Detailed Description
The present application will be described and illustrated with reference to the accompanying drawings and examples for a clearer understanding of the objects, technical solutions and advantages of the present application. However, it will be apparent to one of ordinary skill in the art that the present application may be practiced without these specific details. It will be apparent to those having ordinary skill in the art that various changes can be made to the disclosed embodiments of the application and that the general principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Thus, the present application is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the scope of the application as claimed.
Embodiments of the application are described in further detail below with reference to the drawings.
A blockchain is a chain of blocks. Each block holds a certain information, which are linked in a chain according to the time sequence of their respective generation. This chain is kept in all servers, and the entire blockchain is secure as long as one server in the entire system can work. These servers are referred to as nodes in a blockchain system, each of which may participate in the maintenance and management of the blockchain. Nodes are the basic components of a blockchain, which together form a blockchain network by communicating with each other, exchanging data, authenticating information, etc., and which provide storage space and computational support for the entire blockchain system. If the information in the blockchain is to be modified, it is necessary to sign consent of more than half of the nodes and modify the information in all the nodes, which are usually held in different subject hands, so it is an extremely difficult thing to tamper with the information in the blockchain. Compared with the traditional network, the blockchain has two main core characteristics: firstly, the data is difficult to tamper, and secondly, the data is decentralised.
Fig. 1 is a block diagram of a blockchain-based asset management method provided in this embodiment. As shown in fig. 1, the blockchain-based asset management method includes the steps of:
step S100, obtaining management information sent by a user side, judging whether the certification information in the management information is effective, and broadcasting the management information if the certification information is effective, wherein the management information comprises a management request and corresponding certification information.
The asset management work requires three parties, namely a user end, a block chain end and an asset management end, to participate together. The user terminal is mainly used for assisting a user to transmit management information to the block chain end; the asset management side is mainly used for dialing corresponding funds to the user; the block chain end is mainly used for guaranteeing that management information provided by a user is not tampered by other parties and checking whether funds which are ready to be dialed to corresponding users by an asset management party are correct. Communication connection channels are arranged among the client, the block chain end and the asset management end, and communication among the client, the block chain end and the asset management end can be realized according to the communication channels.
A management information includes a management request and a corresponding set of attestation information. Wherein, the management request characterizes the reimbursement amount of something in a certain period of time when a certain user requests reimbursement, the reimbursement amount is the total amount of reimbursement of the user request, and one management request corresponds to a uniquely determined user one by one. The certification information represents information of at least one mode such as transfer records, invoices or purchase records for certifying the authenticity of the reimbursement request, a group of certification information at least comprises information of one mode, a group of certification information at least comprises one certification sub-information, and each sub-certification information corresponds to the actual use of reimbursement amount. For example, one management information includes a management request by the user a requesting to cancel 2023, 6, and 6 for purchasing office supplies 300 units, and a set of sub-certification information for purchasing paper 100 units and sub-certification information for purchasing print cartridges 200 units, and then a set of certification information corresponding to the management request includes two sub-certification information. If the two pieces of sub-proof information belong to the information of one mode, the group of proof information comprises the information of one mode; if the two pieces of sub-certification information belong to different ways of information, then the group of certification information includes two ways of information.
Each user corresponds to a respective user terminal, and the user inputs management information at the user terminal so that the user terminal obtains the management information. And each user terminal establishes communication connection with the block chain end, so that once the user terminal receives the management information, the management information is automatically sent to the block chain end through the established communication connection channel, and the block chain end acquires the management information sent by the user terminal. Since the management request in the management information already carries the source characterizing the management information, the block chain end can distinguish each acquired management information, i.e. which user each management information corresponds to. Each user has a corresponding user terminal, and the block chain end can simultaneously receive the management information sent by a plurality of user terminals due to the distributed characteristic of the block chain, so that when a plurality of users simultaneously send the management information, the block chain end can simultaneously receive the management information sent by the user terminals without the need of the user terminals to send the management information in a queuing mode, and once a communication channel is established between the user terminal and the block chain end, the management information can be quickly sent to the block chain end based on the channel.
After the block chain end acquires the management information, all modes contained in the certification information can be obtained by checking sub-certification information contained in the certification information, wherein all modes at least comprise one of octography, transfer time or transfer party. If the proving information adopts a transfer recording mode, the transfer time and the transfer party of the proving information can be obtained by checking the management information; if the proving information adopts an invoice mode, a transfer party or a transfer party and a stamp of the proving information can be obtained by checking the management information; if the certification information adopts a purchase record, the transfer time and the transfer party of the certification information can be obtained by checking the management information. The application defaults that the seal marks in the proving information are all real seal marks, and if the sub proving information adopts an invoice mode and the sub proving information has no seal marks, whether the transfer party is effective or not is not considered, and the sub proving information is invalid. Checking the validity of the transfer party by checking whether the attribute corresponding to the transfer party is consistent with the purchased attribute in the management request and belongs to the specified purchasing attribute, and if so, the transfer party is valid; otherwise, the transfer party is not valid. For example, the transfer party is effective if the corresponding attribute is office supply merchant, and the purchased article in the management request also belongs to office supply, and the office supply belongs to the prescribed purchasing attribute. Wherein the prescribed purchasing attributes include, but are not limited to, office supplies, public supplies, cleaning supplies. The validity check for the transfer time can be performed by judging whether the transfer time is a workday and is consistent with the time of the management request, if the transfer time is a workday and is consistent with the time of the management request, the transfer time is valid; otherwise, the transfer time is not valid.
Firstly, checking the proving information in the management information to obtain which sub proving information the proving information comprises, then obtaining all the modes contained in the proving information by the corresponding mode of each sub proving information, and then verifying all the modes contained in the proving information by adopting the methods for verifying the validity of the different modes, wherein if all the modes are valid, the proving information in the management information is valid; otherwise, the certification information in the management information is invalid. The management information is broadcast only if the certification information is valid, so that the block chain end actively verifies whether the certification information is valid or not before broadcasting the management information, and does not propagate invalid management information to the node in preparation for subsequent verification of whether the pre-funded funds are correct.
Fig. 2 is a block diagram of a method for broadcasting management information according to an embodiment of the present application. As shown in fig. 2, broadcasting the management information includes the steps of:
step S101, obtaining a proving format of proving information in the management information, judging whether the proving format is a preset format, and broadcasting the management information in all nodes by adopting an optimization strategy propagation mode if the proving format is the preset format, wherein the optimization strategy propagation mode is any one of layered broadcasting, selecting trust nodes and limiting a broadcasting range.
Step S102, if not, the certification information is converted into new certification information in a preset format by using a preset conversion model corresponding to the certification format, and the new certification information and the corresponding management request are broadcasted in all nodes by adopting an optimization strategy propagation mode, wherein the new certification information and the corresponding management request form new management information.
Each piece of sub-proof information in the proof information can be any one of a picture format, a pdf format and a word format, and the received suffix of each piece of sub-proof information can be checked to obtain the proof format of the proof information in the management information, and at least one of the proof formats of one group of proof information can be obtained. The preset format may be one of the above-mentioned picture format, pdf format, and word format, and considering that corresponding photos are placed in the pdf format and the word format, under the condition of the same information amount, less flow is required in the transmission process of the certification information corresponding to the picture format, and the picture format is preferentially used as the preset format in this embodiment. If the proving format in the group of proving information is only a preset format, the proving format is the preset format; if the certification format in the set of certification information has other certification formats than the preset format, the certification format is not the preset format.
Under the condition that the proving format is the preset format, the node receiving the management information adopts any one of the optimized strategy propagation modes of layered broadcasting, selecting trust nodes and limiting broadcasting range to broadcast the management information to other nodes at the chain end of the block. The hierarchical broadcasting is to divide the network into different levels, and broadcast to adjacent nodes first, so as to gradually enlarge the broadcasting range to realize the whole broadcasting. The trust node is selected by selecting a specific node with higher broadband, higher computing power, more reliable network connection and the like in the network as the trust node, and setting the specific node as the starting point of broadcasting. Limiting the broadcast range refers to limiting the range of each broadcast. The speed of broadcasting management information to all nodes is improved by adopting the optimized strategy propagation mode.
Under the condition that the proving format is not the preset format, the node receiving the management information firstly converts the proving information into new proving information in the preset format through a preset conversion model corresponding to the proving format. The preset conversion model may be a third party format conversion tool or software which is deployed at the chain end of the block and can convert other proof formats which are not preset formats into preset formats, or may be an intelligent contract which is deployed at the chain end of the block and is provided with corresponding programs for converting various proof formats into preset formats, and the new proof information belonging to the preset formats can be obtained by the intelligent contract of the proof information of other proof formats. The new certification information and the corresponding management request form new management information, so that the node receiving the management information adopts any one of the optimized strategy propagation modes of layered broadcasting, selecting trust nodes and limiting broadcasting range to broadcast the converted new management information to other nodes at the end of the block chain. Therefore, the certification information in the management information is unified in format before the management information is broadcasted, and compared with the case that all the management information is broadcasted by using the certification format which is not unified, the method can save the flow consumed in the broadcasting process and relieve the pressure of block chain ends; on the other hand, compared with broadcasting management information which is not subjected to format conversion, the intelligent contracts deployed by all nodes are used for format conversion, so that the deployment quantity of the intelligent contracts is reduced, and the pressure of block chain ends is relieved.
Step S200, judging whether the broadcasting work of the management information is completed, if yes, sending the management request to the asset management end.
After the management information is broadcasted, whether the broadcasting work of the management information is finished is further required to be judged, the block chain end sends the management request to the asset management end only after the block chain end finishes the broadcasting of the management information, so that the block chain end can normally and orderly perform consensus based on the broadcasted management information after receiving the pre-fund sent by the asset management end, useless works such as the subsequent management information sending and receiving the pre-fund and the like are reduced under the condition that the broadcasting work is not finished, and the consensus result obtained by performing the consensus operation before the broadcasting is not finished is unreliable after all. Wherein, judging whether the broadcasting work of the management information is completed comprises the following steps:
step S201, obtaining the memory pool state corresponding to each node at fixed time intervals, obtaining the number of the broadcasted nodes based on the memory pool state, judging whether the number of the nodes is larger than the preset number of the nodes, and if so, completing the broadcasting work of the management information, wherein the preset number of the nodes is not smaller than half of the total number of all the nodes.
Step S202, otherwise, the broadcasting work of the management information is not completed.
Each node in the blockchain has a memory pool to maintain transactions that have not been packed into blocks, and when a node receives broadcasted management information, it will be added to the memory pool. The memory pool state is specifically a first state in which broadcast management information is stored or a second state in which broadcast management information is not stored, and whether the management information exists in the memory pool corresponding to each node is checked at fixed intervals, so that the memory pool state corresponding to each node can be obtained, and the number of the nodes which have been broadcast can be obtained by counting the number of the memory pools in the first state. The number of total nodes in a block chain end is known. The number of the preset nodes is not less than half of the total number of all nodes at the chain ends of the block. If the number of nodes in the first state is greater than the preset number of nodes, the block chain end is indicated to complete the broadcasting work, and the management request can be sent to the asset management end.
If the number of the nodes in the first state is not greater than the preset number of nodes, indicating that the broadcasting work is not completed at the end of the block chain, acquiring the broadcasting time of the current broadcasting, judging whether the broadcasting time is less than the preset reference broadcasting time, and if not, generating an alarm signal representing stopping asset management according to the management information. If the state is smaller than the preset value, continuing to wait for next acquisition of the memory pool state corresponding to each node.
The link ends store the reference broadcast time expected for one broadcast, which characterizes the longest broadcast time allowed for the link ends. The broadcast time characterizes the time it takes for the block chain end to broadcast a management message. If the broadcasting time is not less than the reference broadcasting time, the broadcasting time of the block chain end for broadcasting the management information is indicated to be longer than the allowed longest broadcasting time, the broadcasting time may be abnormal, an alarm signal for representing stopping asset management according to the management information is generated, the block chain end does not broadcast any more, and a management request is not sent to the asset management end any more, so that a worker can know the condition of asset management work in time according to the alarm signal, and the worker knows that the asset management work is not completed. If the broadcasting time is less than the reference broadcasting time, the broadcasting time of the block chain end for broadcasting the management information does not exceed the allowed longest broadcasting time, the method can continue waiting for the fixed time to acquire the memory pool state corresponding to each node next, and continue judging whether the broadcasting work of the management information is completed. Thus, as long as the broadcasting work of the management information is not completed and the broadcasting time is smaller than the reference broadcasting time, the next time of obtaining the memory pool state corresponding to each node is continued to be waited, and the broadcasting work of the management information is completed to the greatest extent possible.
Step S300, the characteristic asset management end sent by the asset management end is received to dial out corresponding pre-money fund according to the management request, and the pre-money fund is identified based on the proving information.
After the asset management end receives the management request sent by the block chain end, an asset management unit in the asset management end automatically divides the amount of reimbursement expressed in the management request into a money-shifting unit for money shifting, and the money-shifting unit is only controlled by a money-shifting instruction or adjustment information sent by the block chain end. After the funds are stored in the money-dialing unit, the money-dialing unit automatically transmits the characterization asset management end to the block chain end to dial out the corresponding pre-dialing funds according to the management request. And the block chain end automatically broadcasts the pre-fund to all nodes after receiving the pre-fund, so that the nodes at the block chain end can realize consensus on the pre-fund according to the received certification information. Fig. 3 is a block diagram of a method for consensus of pre-funding based on attestation information provided by an embodiment of the present application. As shown in fig. 3, the consensus of the pre-funded funds based on the certification information includes the steps of:
in step S301, each node obtains the sum of the amounts in the corresponding certification information based on the obtained certification information, and determines whether the sum of the amounts is equal to the pre-dialled funds based on the consensus mechanism, if so, the node stores block data corresponding to the pre-dialled funds in the corresponding block.
In step S302, if not, the node does not store the block data corresponding to the pre-fund in the corresponding block.
Step S303, judging whether the block heights of the blocks corresponding to the preset standard-reaching number of nodes are the same, and if so, successfully identifying.
In step S304, if not all of them are identical, the consensus is unsuccessful.
If a certain node of the block chain end does not have a group of proving information in the current management information, a group of proving information in the current management information can be obtained by storing a group of proving information in the current management information to the nearby node, so that each node of the block chain end has a group of proving information in the current management information, the amount of the sub-proving information corresponding to each sub-proving information can be obtained by reading each sub-proving information in the group of proving information, and then the amount of the sub-proving information corresponding to all the sub-proving information in the group of proving information can be overlapped to obtain the sum total value of the proving information. A consensus mechanism is stored at the block chain end, and all nodes at the block chain end fairly and honest compare the sum value with the received pre-dialled funds based on the consensus mechanism. If the node determines that the two are equal in value, the node stores block data in the corresponding block that is consistent with or opposite the value of the pre-fund characterization. If the node determines that the two are not equal in value, then the node does not act, i.e., block data that is consistent with or opposite to the value of the pre-fund representation is not stored in the corresponding block. Each block will increase the height of the block by one height when completing one data storage operation.
The preset standard reaching number is the number set by the common mechanism in step S301, where the preset standard reaching number is at least not less than half of the number of nodes capable of performing common identification, by obtaining the height of the block corresponding to each node, and then counting the number of the first nodes corresponding to the same block height, if the largest number in the number of the first nodes is not less than the preset standard reaching number, it is indicated that the block heights of the blocks corresponding to the preset standard reaching number are all the same, and then the block chain ends perform common identification on the preset money drawing funds successfully. If the largest number in the first node number is smaller than the preset standard reaching number, the block heights of blocks corresponding to the nodes without the preset standard reaching number are the same, and then the block chain end pair and the preset money drawing fund are not successfully shared. Therefore, whether the pre-fund withdrawal is successfully identified can be simply and intuitively judged only by comparing the number of the blocks corresponding to the nodes in the block chain with the preset standard reaching number.
Step S400, if the consensus is successful, sending a money dialing instruction which characterizes that the asset management end can automatically send the pre-money dialing fund to the corresponding user to the asset management end.
And S500, if the consensus is not successful, generating adjustment information based on the certification information corresponding to the management request, and sending the adjustment information to the asset management terminal to adjust the pre-money fund sent to the corresponding user by the asset management terminal.
If the block chain end is successful in consensus, the fact that the pre-money amount automatically divided into the money-dialing units by the asset management end is accurate is indicated, then the block chain end can send a money-dialing instruction to the asset management end, so that only the money-dialing units in the asset management end act, the pre-money-dialing fund in the asset management end is sent to the user in the corresponding management request, and accordingly asset management work is accurately completed, even if the user end and the asset management end are subjected to outside malicious attack, the block chain end can also carry out operations such as validity, broadcasting and consensus of verification information and the like because of the block chain end, the influence of outside malicious attack on the block chain end is reduced, and the risk of reimbursement work in the asset management is reduced.
If the block chain ends have no consensus success, the asset management end is possibly attacked by outside malicious, the pre-money amount automatically divided into money-dialing units is inaccurate, namely the reimbursement amount which is intended to be dialed to the corresponding user by the asset management end is different from the reimbursement amount requested by the user. The block chain end can generate adjustment information by calculating the difference between the amount represented by the proof information and the pre-money-dialing funds, and send the adjustment information to a money-dialing unit in the asset management end, so that the money-dialing unit determines whether to require the asset management end to automatically divide the amount represented by the adjustment information to the money-dialing unit again according to the value represented by the adjustment information, or to remove the amount stored in the money-dialing unit from the amount represented by the adjustment information, and returns the removed amount to the asset management unit in the asset management end. After the amount in the money-shifting unit is adjusted, the last stored amount in the money-shifting unit is the amount that the asset management end needs to send to the user in the corresponding management request. Therefore, even if the user terminal and the asset management terminal are attacked by outside maliciously, the operation such as validity, broadcasting and consensus of the verification information of the block chain end can be performed, and under the condition that the consensus is unsuccessful, an adjustment message is sent to the asset management terminal, so that the asset management terminal adjusts the pre-money-dialing funds sent to the corresponding user, the asset management is accurately performed, and the risk of reimbursement work in the asset management is reduced.
Wherein generating adjustment information based on the attestation information corresponding to the management request includes: subtracting the sum total value from the pre-dialling funds to obtain a pre-dialling difference value, judging whether the pre-dialling difference value is larger than zero, and if so, taking the pre-dialling difference value as first adjustment information which is used as an asset management end and is required to be sent to corresponding users on the basis of the pre-dialling funds; if the preset money difference value is smaller than zero, the preset money difference value is used as second adjustment information which is supposed to be sent to the corresponding user by the asset management end on the basis of preset money. The adjustment information includes first adjustment information and second adjustment information. That is, the difference value of the pre-dialing money is larger than zero, which indicates that the amount of money in the dialing unit is larger than the amount of money actually required to be sent to the user in the corresponding management request, then the first adjustment information generated at the end of the block chain is the information for the dialing unit to shift the amount of money stored in the dialing unit out of the amount of money represented by the adjustment information according to the value represented by the adjustment information, and the shifted-out amount of money is returned to one of the asset management units in the asset management end. The difference value of the pre-dialing money is smaller than zero, which indicates that the amount of money in the dialing unit is smaller than the amount of money actually required to be sent to the user in the corresponding management request, and then the second adjustment information generated at the end of the block chain is one piece of information which enables the dialing unit to automatically divide the amount of money represented by the adjustment information to the dialing unit again according to the value represented by the adjustment information. The money shifting unit of the asset management terminal can make corresponding actions after receiving the first adjustment information or the second adjustment information, so that asset management work is accurately completed.
In addition, if the block chain ends do not have successful consensus, the block chain ends also generate early warning signals, and the early warning signals are sent to the asset management end, so that the asset management end can timely know whether the amount of money dialing made by the asset management end according to the management request is accurate. The block chain ends also count the times of generating early warning signals, so that a reference is provided for the subsequent evaluation of the self-safety of the asset management end according to the times.
