Detailed Description
As described above, the charitable fund management method which is common at present is an autonomous accounting method, and the inventor finds that: the autonomous accounting mode can lead the public to be incapable of supervising the accounting nodes, the accounting process and the accounting results, and lead the public to doubt the accuracy of the accounting book information. This doubt directly results in a reduced confidence level of the data being billed, and thus a reduced social credibility of the charitable fund platform. Therefore, the inventor starts from two aspects of accounting nodes and accounting supervision, selects the accounting nodes with high credit to carry out accounting, supervises accounting in a decentralized mode, avoids any platform from tampering accounting data at will, and solves the problem of low social public credibility of the platform caused by low credibility of the accounting data.
The application is operational with numerous general purpose or special purpose computing device environments or configurations. Such as a personal computer, server computer, hand-held or portable device, tablet-type device, multi-processor arrangement, distributed computing environment including any of the above devices or apparatus, and the like.
The embodiment of the application provides a fund management method which can be used in various fields such as the field of artificial intelligence, the field of block chains, the field of distributed type, the field of cloud computing, the field of big data or the field of finance. The foregoing is merely an example, and does not limit the application field of the fund management method provided by the present invention.
Fig. 1 is a flowchart of a fund management method provided in an embodiment of the present application, including the following steps:
s101: fund transaction information is obtained.
The fund transaction information needs to be acquired before the system manages the fund. The fund transaction information refers to fund information for donation of individuals or organizations to charitable organizations, or fund donation information for fund donation of charitable organizations to individuals or organizations. The fund information includes fund number and basic donor information, and the fund donation information includes fund use number and basic user information. The basic donor information includes personal age, sex, occupation, etc., and the basic user information includes user age, occupation, reason for use, etc.
S102: and acquiring a target accounting node by using a preset algorithm.
After the system acquires the fund transaction information, a target accounting node needs to be acquired by using a preset algorithm. The target accounting node is a node for performing accounting in charitable fund management. The nodes comprise charitable fund union nodes, donator nodes, bank nodes, supervision nodes, charitable use authority nodes, identity authentication nodes and donator nodes. In the embodiment of the present application, a federation chain is formed by the nodes, and the federation chain is a chain structure formed based on the block chain technology. Where the node may perform the admission and withdrawal operations.
In this embodiment of the application, the target accounting node is a node with a credit value higher than a first preset credit threshold. Wherein the credit value is used for representing the trust degree of the public to really bill the node. For example, if the credit value of the supervising node is 95 and the credit value of the charitable foundation league node is 90, the public has a higher level of trust in the real billing of the supervising node than in the charitable foundation league node.
In the embodiment of the present application, the preset algorithm may be an improved PBFT algorithm, and is specifically obtained by the following method:
firstly, acquiring an accounting node cluster based on a preset algorithm. The accounting node cluster refers to a plurality of node sets with a plurality of accounting possibilities, and comprises a plurality of accounting nodes. Specifically, whether the node is the accounting node can be determined by judging whether the credit value of the node is greater than a second preset credit threshold value. And if the credit value of the node is greater than the second preset information threshold value, marking the node as a billing node, otherwise, marking the node as a participating node. In this embodiment, the second preset credit threshold may be a median of the node credit values. For example, 6001 total fund nodes are ranked according to their credit values from large to small or from small to large, and the credit value of the middle node is the second predetermined credit threshold. Thus, if the credit value of the node is higher than that of the most middle node, the node is marked as the accounting node, so that the accounting node cluster consisting of more than 300 accounting nodes can be obtained. Wherein, the accounting node is a node with accounting possibility. In this case the number of determined accounting nodes is sufficient. Therefore, multi-node endorsement can be ensured, and the cost of tampering data is increased.
And secondly, selecting nodes with the node credit values larger than a first preset credit threshold value from the accounting node cluster as target accounting nodes. In an embodiment of the present application, the first preset credit threshold may be a credit value of a last node of nodes whose credit values rank 5% first. For example, if the credit value of the last node is 95, the first predetermined credit threshold is 95 if the top 5% of the 3000 nodes are selected to have 150 nodes. In this way, it is ensured that the credit value of the node which becomes the target accounting node is sufficiently high, and the social public trust is also sufficiently high. Thus, the stronger the willingness to donate by the public, the more the fund will acquire, the stronger the fund will act, and the greater the social influence will be.
Optionally, the accounting node cluster includes a first accounting node. And judging whether the credit value of the first accounting node is greater than a first preset credit threshold value or not, if so, marking the first target accounting node as the first target accounting node, and accounting by using the first target accounting node as the only target accounting node.
Optionally, the accounting node cluster further includes a second accounting node in addition to the first accounting node, and determines whether credit values of the first accounting node and the second accounting node are greater than a first preset credit threshold, if so, the first accounting node is marked as a first target accounting node, and the second accounting node is marked as a second target accounting node. The first target accounting node and the second target accounting node are randomly sequenced and become target accounting nodes for accounting in sequence. If not, the method is divided into three conditions, wherein one condition is that the credit value of the first accounting node is larger than a first preset credit threshold value, the first accounting node is marked as a first target accounting node at the moment, and the first accounting node is the only target accounting node for accounting; the other is that the credit value of the second accounting node is greater than a first preset credit threshold value, at this time, the second accounting node is marked as a second target accounting node and is the only target accounting node for accounting; and the third method is that the credit values of the first accounting node and the second accounting node are not more than the first preset credit threshold value, so that the requirements are not met and the accounting is not carried out.
The target accounting node obtained by the method is a node with a higher credit value, so that the authenticity and the credibility of the accounting node can be ensured, and the credibility of the data is further improved in the aspect of data recording.
S103: and acquiring an accounting result according to the target accounting node and the fund transaction information.
And after the system obtains the target accounting node with higher credit value, the target accounting node records the fund transaction information to obtain an accounting result. In embodiments of the present application, the billing results may be stored in accordance with a blockchain data structure. The block chain data structure is a chain data structure composed of data blocks connected in sequence according to a time sequence. This way of storing data in units of blocks, since there is no centralized hardware or management mechanism, the rights and obligations of any node are equalized, and the data blocks in the system are commonly maintained by the nodes having the maintenance function in the entire system. Therefore, the block chain data can ensure that no structure can randomly tamper with the data, and the reliability of the data is improved.
Specifically, the blocks in the block chain type data structure are composed of a block header and a block body, and all the blocks can form a chain structure according to the hash value, so that the blocks jointly act to form a distributed book of a block chain, namely the block chain type data structure is jointly formed. The hash value of each block is formed by hashing the hash values of the transaction data in the blocks to form the root of a Merkle (Merkle) tree and the hash value of the previous block, so that any change of the transaction data can not only affect the block but also affect the following blocks successively, thereby preventing the data from being tampered.
S104: and synchronously sending the accounting result to a plurality of nodes for recording.
And when the accounting result is obtained, the accounting result is broadcast to the whole network simultaneously so as to be synchronously sent to a plurality of nodes for recording. Therefore, all nodes have the full amount of book data, so that multi-node endorsement of transaction data is realized, and the cost for tampering the transaction data is further increased. In this way, the trustworthiness of the data can be enhanced by the non-tamperable nature of the data. Optionally, in the embodiment of the present application, a chain data structure is used for distributed storage, and all information in a chain is published to a whole network and subjected to distributed accounting. In this way, each person can be queried and traced for each transaction. Optionally, the chain data structure stores the manner of direct association between the donator and the donated item, so that each person can know the specific details of the donation, including who the corresponding recipient of each money is, how to use, how to issue several times, how to achieve the rescue effect, and the like. Thus, in this way, charitable activities can be guaranteed to meet the requirements of openness, transparency and traceability.
In the embodiment of the present application, in order to synchronously send the accounting result to a plurality of nodes for recording, an asymmetric encryption algorithm may be used for sending. Specifically, firstly, the accounting result is encrypted by using an asymmetric encryption algorithm, and then the encrypted accounting result is synchronously sent to a plurality of nodes for recording. In this way, the security and confidentiality of data can be ensured when the node information is transmitted, and the validity of the sender and the information can be verified.
In this embodiment of the present application, the fund management method may further include determining whether the target billing result is correctly billed, and if so, increasing the credit value of the target billing node. If not, the credit value of the target billing node is decreased. Fig. 2 shows a node development pattern based on credit incentive provided by an embodiment of the present application. The charitable fund A which becomes a target accounting node has higher credit value and higher social public trust, so that the public is more willing to donate, the more the credit is obtained, the stronger the sending function is, and the social influence is larger. And the civil administration increases the credit value of the target accounting node according to the correct accounting result of the charitable fund A. Therefore, the credit value of the charitable fund A is higher, the social public trust is stronger, and the processes are circulated in sequence. The incentive nodes strive to be target accounting nodes, so that the sustainable development of the fund management system is realized.
When the method is executed, the platform firstly acquires fund transaction information, screens out nodes with higher credit values by using a preset algorithm as target accounting nodes for accounting, and synchronously sends accounting results to a plurality of nodes for recording. The decentralized mode of synchronously sending accounting results to a plurality of nodes for recording is adopted, so that any platform can be prevented from randomly tampering data. Therefore, the data reliability of the bookkeeping can be enhanced, and the social public credibility of the platform is further improved. In addition, by adopting the mode of carrying out accounting by the nodes which are most trusted by the public, the reliability of the accounting nodes can be ensured to be high, and the data reliability can be further improved from the aspect of data recording.
In this embodiment of the application, there are many possible implementations of step S102 described in fig. 1, which are described below. It should be noted that the implementations given in the following description are only exemplary and do not represent all implementations of the embodiments of the present application.
Referring to fig. 3, it is a flowchart of a target billing node acquisition provided in this embodiment of the present application. As can be seen from fig. 3, the specific implementation manner of step S102 includes:
s301: and building a chain structure of the bottom layer nodes.
In the embodiment of the present application, the bottom nodes include a chain structure composed of a donor node a, a charitable fund alliance B, a donor node C, a bank node D, a supervision node E, an identity authentication node F, and a charitable use authority node G, and the specific structure refers to fig. 4. Fig. 4 is a multi-node chain structure diagram according to an embodiment of the present application. Wherein the charitable foundation league D comprises a plurality of charitable foundation nodes. The chain structure can be automatically networked by the P2P networking mechanism. For example, when a node is newly added, the newly added node can be automatically brought into the chain structure; if the node exits, the chain structure can automatically delete the node and the information.
S302: a predetermined algorithm is selected from the consensus layer.
The consensus layer of the charitable fund management system encapsulates various consensus mechanism algorithms of the network nodes. The consensus mechanism algorithm is used as the core of the whole system and determines who accounts. And the choice of accounting node affects the reliability and security of the whole system. In the embodiment of the application, the improved practical Byzantine fault-tolerant algorithm PBFT consensus mechanism is selected by the preset algorithm. The improved PBFT consensus mechanism has the consistency protocol, the view replacement protocol and the checkpoint protocol which are possessed by the PBFT consensus mechanism. In addition, the node which needs accounting is determined to have the particularity.
S303: and aiming at the nodes in the block chain, acquiring all possible target accounting nodes by using a preset algorithm.
Each node in the blockchain judges whether the node has the possibility of being used as a target accounting node by using a preset algorithm. All nodes that may be targeted accounting nodes, if any, are marked and stored. For example, possible target accounting nodes are obtained, including target accounting node 1, target accounting node 2, and target accounting node 3.
S304: and randomly sequencing all possible target accounting nodes, and sequentially using the nodes as the target accounting nodes for accounting.
For example, the 1 st target accounting node, the 2 nd target accounting node and the 3 rd target accounting node are randomly sequenced to be the 3 rd target accounting node, the 2 nd target accounting node and the 1 st target accounting node. Firstly, the 3 rd target accounting node is used as a target accounting node for accounting; billing is then performed … … using the 2 nd target billing node as the target billing node. And the same is repeated until the last target accounting node (namely the 1 st target accounting node) is used as the target accounting node for accounting.
S304: and judging the accounting correctness of the accounting result of the target accounting node, if the accounting result is correct, increasing the credit value of the target accounting node, and replacing the credit value of the original target accounting node with the credit value to be used as the selection of the next accounting node.
In the embodiment of the application, the credit value of the node is continuously optimized and adjusted in a credit incentive mode, so that the node can be encouraged to contend for a target accounting node, and the correctness of the account book jointly maintained by the nodes on the chain is promoted through the credit incentive. Thus, the health and sustainable development of the fund management system can be realized.
Referring to fig. 5, a flow chart of a specific improved PBFT consensus mechanism provided by an embodiment of the present application is shown. As can be seen from fig. 5, determining the node that needs to be billed specifically includes:
s501: the number of charitable foundation sessions is determined.
S502: the charitable fund nodes are sorted from small to large according to the credit value size, and ordered charitable fund node groups are obtained.
S503: and taking the most middle charitable fund node A, and obtaining a credit threshold value a corresponding to A.

And sequentially obtaining a plurality of accounting nodes to form an accounting node cluster.
And marking the nodes with the nodes less than or equal to the credit threshold value a as participating nodes.
S505: and arranging the accounting nodes in the accounting node cluster from small to large in sequence, selecting the node B from the accounting nodes, wherein the credit values of the node B are arranged in the accounting node cluster, and the credit values B of the node B are obtained, wherein the credit values of the node B are ranked 10%.
S506: and judging whether the credit value of the accounting node is greater than the credit value b, if so, taking the accounting node as a target accounting node to perform accounting.
S507: and packaging the operation flow in a network layer, and then taking the operation flow as a preset algorithm for subsequent calling.
Through the preset algorithm, the credit degree of the selected accounting node can be made higher. In the aspect of selection of the accounting nodes, the mode of accounting by the most trusted public nodes can ensure high reliability of the accounting nodes, so that the data reliability is further improved in the aspect of data recording.
