Description

Blockchain-based asset management methods, systems, servers and storage media

Technical field

This application relates to the field of blockchain technology, especially to asset management methods, systems, servers and storage media based on blockchain.

Background technique

The asset management work of an enterprise refers to the effective management and control of various types of assets of the enterprise to protect the property safety of the enterprise, improve the efficiency of asset utilization, reduce operating costs, and enhance the competitiveness of the enterprise. Among them, management and control include not only reasonable planning, but also accurate reimbursement. No matter how good the plan is, it will not be able to complete the asset management of the enterprise if it encounters chaotic asset reimbursement. Therefore, reasonable planning and accurate reimbursement are an indispensable part of completing the asset management of the enterprise.

The reimbursement part of traditional asset management work is through the person who needs reimbursement sending the reimbursement request and related certification materials to the corresponding staff, and the staff completes the reimbursement work based on the reimbursement request and related certification materials. However, this There is a possibility that certification materials or reimbursement requests may be tampered with or forged during the process, making it difficult to effectively guarantee the authenticity of the final reimbursement results, making reimbursement work in asset management risky.

At this stage, the main goal is to deploy asset management work into the blockchain to reduce the occurrence of tampering or forgery of certification materials, thereby indirectly reducing the risk of asset management work. That is, those who need reimbursement first store the relevant certification information directly in the blockchain to reduce the possibility of tampering with the certification information by involving other personnel; then send the reimbursement request to the corresponding asset management end, so that the asset management The client actively searches the blockchain for relevant certification materials to complete the reimbursement work in asset management, thereby achieving the above purpose.

However, once the number of reimbursement requests increases, the existing method will make the asset management end face multiple reimbursement requests at the same time. On the one hand, it will put invisible pressure on the asset management end to receive requests and increase the probability of the asset management end crashing. The purpose of reducing the risk of asset management work cannot be effectively achieved; on the other hand, it will also put pressure on the asset management side to process reimbursement work, increase the probability of errors in the asset management side processing process, and cannot effectively reduce the risk of asset management work. risk for this purpose.

Detailed ways

In order to understand the purpose, technical solutions and advantages of the present application more clearly, the present application is described and illustrated below in conjunction with the drawings and embodiments. However, one of ordinary skill in the art will understand that the present application may be practiced without these details. It is obvious to those of ordinary skill in the art that various changes can be made to the embodiments disclosed in this application, and the general principles defined in this application can be applied to other applications without departing from the principles and scope of this application. Examples and application scenarios. Accordingly, this application is not to be limited to the embodiments shown but is to be accorded the widest scope consistent with the scope of this application.

The embodiments of the present application will be described in further detail below with reference to the accompanying drawings.

Blockchain is a chain composed of blocks one after another. Each block stores a certain amount of information, and they are connected into a chain in the order in which they were generated. This chain is saved in all servers. As long as one server in the entire system can work, the entire blockchain is safe. These servers are called nodes in the blockchain system, and each node can participate in the maintenance and management of the blockchain. Nodes are the basic components of the blockchain. They form a blockchain network by communicating with each other, exchanging data, verifying information, etc. They provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different subjects, so it is extremely difficult to tamper with the information in the blockchain. thing. Compared with traditional networks, blockchain has two core characteristics: first, data is difficult to tamper with, and second, it is decentralized.

Figure 1 is a block diagram of the blockchain-based asset management method provided in this embodiment. As shown in Figure 1, the blockchain-based asset management method includes the following steps:

Step S100: Obtain the management information sent by the client, determine whether the certification information in the management information is valid, and if valid, broadcast the management information, where the management information includes the management request and the corresponding certification information.

Asset management requires the participation of three parties: the user end, the blockchain end and the asset management end. Among them, the user side is mainly used to assist users in transmitting management information to the blockchain side; the asset manager is mainly used to allocate corresponding funds to users; the blockchain side is mainly used to ensure that the management information provided by users is not tampered with by other parties. , and check whether the funds that the asset manager intends to allocate to the corresponding users are correct. There is a communication connection channel between the user end, the blockchain end and the asset management end, and communication between each other can be achieved through this channel.

A management message includes a management request and a corresponding set of certification information. Among them, the management request represents a user's request to reimburse the reimbursement amount of something within a certain period of time. The reimbursement amount is the total amount of the user's request for reimbursement. A management request has a unique and unique user. The certification information represents at least one form of information such as transfer records, invoices or purchase records used to prove the authenticity of the reimbursement request. A set of certification information includes at least one form of information, and a set of certification information includes at least one certification sub-section. Information, each sub-certification information corresponds to an actual use of the reimbursement amount. For example, a piece of management information includes a management request from User A to reimburse 300 yuan for office supplies purchased on June 6, 2023, and a set of sub-certification information for purchasing paper for 100 yuan and sub-certification information for purchasing print cartridges for 200 yuan, then The set of certification information corresponding to the management request includes two sub-certification information. If the two sub-certification information both belong to one of the above methods, then the group of certification information includes information of one method; if the two sub-certification information belong to different methods of information, then the group of certification information includes two types of information. way information.

Each user corresponds to his or her own client, and the user inputs management information into his own client so that the client can obtain the management information. Each user terminal establishes a communication connection with the blockchain terminal, so that once the user terminal receives the management information, it will automatically send the management information to the blockchain terminal through the established communication connection channel, so that the blockchain terminal can obtain Management information sent to the client. Since the management request in the management information already carries the source of the management information, the blockchain end can distinguish each management information obtained, that is, which user each management information corresponds to. Each user has its own corresponding client, and the distributed characteristics of the blockchain allow the blockchain to receive management information sent by multiple users at the same time. In this way, when multiple users send management information at the same time, the blockchain The client can receive the management information sent by these clients at the same time without having to wait in line to send the management information, so that once the client establishes a communication channel with the blockchain client, it can quickly send the management information based on the channel. Management information is sent to the blockchain side.

After the blockchain side obtains the management information, it can obtain all the methods contained in the certification information by viewing the sub-certification information contained in the certification information in the management information. Among them, all methods include at least the seal, transfer time or transfer party. A sort of. If the certification information is in the form of transfer records, the transfer time and transfer party of the certification information can be obtained by viewing the management information; if the certification information is in the form of invoices, the transfer party or transfer party and seal of the certification information can be obtained by viewing the management information; The information includes purchase records. By viewing the management information, you can obtain the transfer time and transfer party proving the information. This application defaults to the fact that the seals in the certification information are all real seals. If the sub-certification information uses an invoice and there is no seal in the sub-certification information, then there is no need to consider whether the transfer party is valid, and the sub-certification information will be invalid. . The validity of the transfer party can be checked by checking whether the attributes corresponding to the transfer party are consistent with the purchased attributes in the management request and whether they belong to the specified purchasing attributes. If the attributes are consistent and belong to the specified purchasing attributes, the transfer party is valid. ; Otherwise, the transfer party is invalid. For example, if the attribute corresponding to the transfer party is an office supplies merchant, and the items purchased in the management request also belong to office supplies, and the office supplies belong to the specified purchase attributes, then the transfer party is valid. Among them, the specified purchasing attributes include but are not limited to office supplies, public supplies, and cleaning supplies. The validity of the transfer time can be checked by judging whether the transfer time is a working day and whether it is consistent with the time requested by the management. If the transfer time is a working day and consistent with the time requested by the management, then the transfer time is valid; otherwise, the transfer time is valid; otherwise, the transfer time is valid. The transfer time is invalid.

First, by checking the certification information in the management information, you can get which sub-certification information the certification information includes. Then, you can get all the methods included in the certification information through the method corresponding to each sub-certification information. Then, use the above different methods to verify the validity. To verify all the methods contained in the certification information, if all methods are valid, then the certification information in the management information is valid; otherwise, the certification information in the management information is invalid. Only when the proof information is valid, the management information will be broadcast. In this way, the blockchain end will proactively verify whether the proof information is valid before broadcasting the management information, and will not propagate invalid management information to the nodes, which will provide a better way for subsequent Verify that pre-appropriation funds are properly prepared.

Figure 2 is a block diagram of a method for broadcasting management information provided by an embodiment of the present application. As shown in Figure 2, broadcasting management information includes the following steps:

Step S101: Obtain the certification format of the certification information in the management information, and determine whether the certification format is a preset format. If so, use the optimization strategy propagation method to broadcast the management information in all nodes, where the optimization strategy propagation method is hierarchical broadcast, Choose between trusting nodes and limiting the broadcast range.

Step S102, if not, use the preset conversion model corresponding to the certification format to convert the certification information into new certification information in the preset format, and use the optimization strategy propagation method to broadcast the new certification information and corresponding management requests in all nodes, where , the new certification information and the corresponding management request constitute new management information.

Each sub-certification information in the certification information can be in any certification format among picture format, pdf format, and word format. By checking the suffix of each received sub-certification information, the certification format of the certification information in the management information can be obtained. A set of proof information has at least one proof format. The preset format can be one of the above picture formats, pdf format, and word format. Considering that the corresponding photos are also placed in the pdf format and word format, under the same amount of information, the certification information corresponding to the picture format is in the transmission process. Requires less traffic, this embodiment gives priority to the image format as the default format. If the proof format in a set of proof information has only a preset format, then the proof format is the preset format; if the proof format in a set of proof information has other proof formats besides the preset format, then the proof format is not a preset format. Set format.

When the proof format is a preset format, the node receiving the management information uses any optimization strategy propagation method including hierarchical broadcasting, selecting trusted nodes, and limiting the broadcast range to transmit the management information to other nodes on the blockchain. broadcast. Among them, hierarchical broadcast realizes the entire broadcast by dividing the network into different levels and broadcasting to adjacent nodes first, thus gradually expanding the broadcast range. Selecting a trust node is to select a specific node with higher bandwidth, stronger computing power, more reliable network connection, etc. as a trust node in the network and set it as the starting point of the broadcast. Limiting the broadcast range means limiting the range of each broadcast. By adopting the above optimization strategy propagation method, the speed of broadcasting management information to all nodes is improved.

When the proof format is not the preset format, the node receiving the management information first converts the proof information into new proof information in the preset format through the preset conversion model corresponding to the proof format. Among them, the preset conversion model can be deployed on the blockchain side and can convert other certification formats that are not preset formats into the preset format. Third-party format conversion tools or software can also be deployed on the blockchain. A smart contract on the end of the smart contract has corresponding procedures for converting various certification formats into preset formats. New certification information belonging to the preset format can be obtained from certification information in other certification formats through the smart contract. The new certification information and the corresponding management request constitute the new management information, so the node receiving the management information uses any optimization strategy propagation method such as hierarchical broadcasting, selecting trusted nodes, and limiting the broadcast range to convert the converted new management information. Broadcast to other nodes on the blockchain side. In this way, the certification information in the management information is unified in format before broadcasting the management information. On the one hand, compared with broadcasting all management information using the certification format before unification, it can save the traffic consumed during the broadcast process. Alleviating the pressure on the blockchain side; on the other hand, compared with first broadcasting the management information without format conversion, and then using smart contracts deployed by each node to perform format conversion, it will reduce the number of smart contract deployments and solve the problems on the blockchain side. pressure.

Step S200: Determine whether the broadcast of management information is completed. If so, send the management request to the asset management end.

After the management information is broadcast, it is necessary to further determine whether the broadcast of the management information is completed. Only after the blockchain end completes the broadcast of the management information, the blockchain end sends the management request to the asset management end to ensure After receiving the pre-appropriation funds sent by the asset management end, the blockchain end can carry out consensus based on the broadcast management information in a normal and orderly manner, reducing the risk of subsequent management information transmission and failure due to the failure to complete the broadcast work. Useless work such as receiving pre-appropriation funds, after all, the consensus results obtained by performing consensus operations before completing the broadcast are not reliable. Among them, judging whether the broadcast of management information is completed includes the following steps:

Step S201, obtain the memory pool status corresponding to each node at fixed intervals, obtain the number of nodes that have been broadcast based on the memory pool status, and determine whether the number of nodes is greater than the preset number of nodes. If it is greater, the broadcast of the management information is completed. Work, in which the preset number of nodes is not less than half of the total number of all nodes.

Step S202, otherwise, the broadcasting of the management information has not been completed.

Each node in the blockchain has a memory pool to maintain transactions that have not yet been packaged into blocks. When a node receives the broadcast management information, it will be added to the memory pool. The above memory pool state is specifically the first state in which broadcast management information is stored, or the second state in which broadcast management information is not stored. Check whether there is any memory pool corresponding to each node at fixed intervals. With this management information, the memory pool status corresponding to each node can be obtained, and the number of nodes that have been broadcast can be obtained by counting the number of memory pools in the first state. The total number of nodes in the blockchain is known. The above-mentioned preset number of nodes shall not be less than half of the total number of nodes on the blockchain side. If the number of nodes in the first state is greater than the preset number of nodes, it indicates that the blockchain end has completed the broadcast work and can send the management request to the asset management end.

If the number of nodes in the first state is not greater than the preset number of nodes, it indicates that the blockchain has not completed the broadcast work. At this time, the broadcast time of the current broadcast can be obtained to determine whether the broadcast time is less than the preset reference broadcast time. If Not less than, generate an alarm signal indicating the cessation of asset management based on management information. If it is less than, continue to wait for the next acquisition of the memory pool status corresponding to each node.

The blockchain side stores the reference broadcast time expected for a broadcast. The reference broadcast time represents the maximum broadcast time allowed by the blockchain side. The above broadcast time represents the actual time it takes for the blockchain end to broadcast a piece of management information. If the broadcast time is not less than the reference broadcast time, it means that the time for the blockchain end to broadcast this management information has exceeded the maximum allowed broadcast time. This broadcast may be abnormal and generate an alarm indicating that asset management based on the management information has been stopped. Signal, the blockchain end will no longer broadcast, nor will it send management requests to the asset management end. According to the alarm signal, the staff will know the status of the asset management work in a timely manner and know that the asset management work has not been completed. If the broadcast time is less than the reference broadcast time, it means that the time for the blockchain end to broadcast this management information has not exceeded the maximum allowed broadcast time. You can continue to wait for a fixed time and then obtain the memory pool status corresponding to each node next time. , and continue to determine whether the broadcast of management information is completed. In this way, as long as the broadcast of management information has not been completed and the broadcast time is less than the reference broadcast time, it will continue to wait for the next time to obtain the memory pool status corresponding to each node, and complete the broadcast of management information to the greatest extent possible.

Step S300: Receive the representation sent by the asset management terminal, the asset management terminal allocates corresponding pre-appropriation funds according to the management request, and reaches a consensus on the pre-appropriation funds based on the certification information.

After the asset management end receives the management request sent by the blockchain end, the asset management unit in the asset management end automatically divides it into the appropriation unit for appropriation based on the reimbursement amount expressed in the management request. The appropriation unit is only subject to Appropriation instructions sent by the blockchain end or adjustment information control. After funds are stored in the appropriation unit, it will automatically be sent to the blockchain end to indicate that the asset management end will allocate corresponding pre-appropriation funds according to the management request. After receiving the pre-appropriation funds, the blockchain end automatically broadcasts to all nodes, so that the nodes on the blockchain end reach consensus on the pre-appropriation funds based on the received certification information. Figure 3 is a block diagram of a method for consensus on pre-appropriation funds based on certification information provided by the embodiment of this application. As shown in Figure 3, consensus on pre-appropriation funds based on proof information includes the following steps:

Step S301: Each node obtains the total amount in the corresponding certification information based on the obtained certification information, and determines whether the total amount is equal to the pre-appropriation funds based on the consensus mechanism. If equal, the node stores the pre-appropriation funds in the corresponding block. The block data corresponding to the funds.

Step S302, if not equal, the node does not store the block data corresponding to the pre-appropriation funds in the corresponding block.

Step S303, determine whether the block heights of the blocks corresponding to the preset standard number of nodes are all the same. If they are all the same, the consensus is successful.

Step S304, if they are not all the same, the consensus is unsuccessful.

If a node on the blockchain side does not have a set of certification information in the current management information, a set of certification information in the current management information can be obtained from a nearby node that stores a set of certification information in the current management information, so that Each node on the blockchain side has a set of proof information in the current management information. By reading each sub-proof information in the set of proof information, the sub-amount corresponding to each sub-proof information can be obtained, and then the set of proof information can be obtained. The total value of the amount in the certification information can be obtained by superimposing the sub-amounts corresponding to all sub-certification information in the information. There is a consensus mechanism stored on the blockchain side, and all nodes on the blockchain side use this consensus mechanism to fairly and honestly compare the total amount with the received pre-appropriation funds. If the node determines that the two values are equal, then the node stores the block data in the corresponding block that is consistent with or the opposite of the value represented by the pre-appropriation funds. If the node determines that the two values are not equal, then the node takes no action, that is, no block data is stored in the corresponding block that is consistent with or opposite to the value represented by the pre-appropriation funds. When each block completes data storage, the height of the block will increase by one.

The above-mentioned preset standard number is the number set by the consensus mechanism in step S301. The preset standard number is at least not less than half of the number of nodes that can perform consensus. By obtaining the corresponding block height of each node, and then counting the block heights belonging to the same Corresponding number of first nodes. If the largest number among the first number of nodes is not less than the preset standard number, it means that the block heights of the blocks corresponding to the preset standard number of nodes are all the same, then the blockchain end pair Pre-appropriation of funds for consensus success. If the largest number of the first number of nodes is less than the preset standard number, it means that the block heights of the blocks corresponding to the preset standard number of nodes are not the same, and the blockchain end fails to reach consensus on the pre-appropriated funds. . In this way, only by comparing the block heights of the blocks corresponding to the nodes in the blockchain to the same number and the preset standard number, we can simply and intuitively judge whether the consensus on the pre-appropriation funds is successful.

Step S400, if the consensus is successful, sending a representation to the asset management terminal allows the asset management terminal to automatically send the pre-appropriation funds to the corresponding user's allocation instructions.

Step S500, if the consensus is not successful, adjustment information is generated based on the certification information corresponding to the management request, and the adjustment information is sent to the asset management end to adjust the pre-appropriation funds sent by the asset management end to the corresponding user.

If the consensus on the blockchain end is successful, it means that the pre-appropriation amount automatically allocated to the appropriation unit by the asset management end is accurate. Then the blockchain end will send an appropriation instruction to the asset management end, so that only the appropriation unit takes action in the asset management end. , the pre-appropriation funds in it are sent to the users in the corresponding management requests, so as to accurately complete the asset management work. In this way, even if the user end and the asset management end are maliciously attacked by the outside world, they will be affected by the blockchain end's own calibration. Verify the validity of information, broadcast and consensus operations to reduce the impact of malicious external attacks on the blockchain side and reduce the risk of reimbursement in asset management.

If there is no consensus on the blockchain side, it means that the asset management side may have been maliciously attacked by the outside world, and the pre-appropriation amount automatically allocated to the appropriation unit is inaccurate, that is, the reimbursement amount that the asset management side intends to allocate to the corresponding user is different from the user. The amounts requested for reimbursement vary. The blockchain end will generate adjustment information by calculating the difference between the amount represented by the certification information and the pre-appropriation funds, and send the adjustment information to the appropriation unit in the asset management end, so that the appropriation unit will The numerical value determines whether to require the asset management end to automatically allocate the amount represented by the adjustment information to the appropriation unit again, or to move the amount stored in its own appropriation unit out of the amount represented by the adjustment information, and return the moved amount to the asset management unit in the asset management end. . After the amount in the appropriation unit is adjusted, the last amount stored in the appropriation unit is what the asset management end needs to send to the user in the corresponding management request. In this way, even if the user end and the asset management end are maliciously attacked by the outside world, due to the blockchain end's own verification of the validity of the information, broadcast and consensus operations, if the consensus is unsuccessful, the asset management end will be sent to the managed asset end. An adjustment information allows the asset management end to adjust the pre-appropriation funds sent to the corresponding users, accurately manage assets, and reduce the risk of reimbursement in asset management.

Among them, generating adjustment information based on the certification information corresponding to the management request includes: subtracting the total amount of the advance appropriation funds to obtain the advance appropriation difference, judging whether the advance appropriation difference is greater than zero, and if it is greater than zero, taking the advance appropriation difference as The asset management end should send less first adjustment information to the corresponding user based on the pre-appropriation funds; if it is less than zero, the pre-appropriation difference will be used as the third adjustment information that the asset management end should send more to the corresponding user based on the pre-appropriation funds. 2. Adjustment information. The adjustment information includes first adjustment information and second adjustment information. That is, the pre-appropriation difference is greater than zero, indicating that the amount in the appropriation unit is greater than the amount that actually needs to be sent to the user in the corresponding management request. Then the first adjustment information generated by the blockchain is the value represented by the appropriation unit based on the adjustment information. A piece of information that moves the amount stored in its own appropriation unit out of the amount represented by the adjustment information and returns the moved amount to the asset management unit in the asset management terminal. The difference in advance appropriation is less than zero, indicating that the amount in the appropriation unit is less than the amount that actually needs to be sent to the user in the corresponding management request. Then the second adjustment information generated by the blockchain is to allow the appropriation unit to require assets based on the numerical value represented by the adjustment information. The management end automatically allocates a piece of information representing the amount represented by the adjustment information to the appropriation unit again. The appropriation unit on the asset management side will take corresponding actions after receiving the first adjustment information or the second adjustment information, so as to accurately complete the asset management work.

In addition, if the consensus on the blockchain end is not successful, the blockchain end will also generate an early warning signal and send the early warning signal to the asset management end, allowing the asset management end to know in a timely manner whether the amount of allocations it has made based on the management request is accurate. A role. The blockchain side also counts the number of times warning signals are generated, so that it can provide a reference for subsequent evaluation of the asset management side's own security.
