Background
The blockchain technique, also known as distributed ledger technique, is essentially a decentralized distributed internet database. A network constructed using blockchain technology can be considered as a blockchain network, where the blockchain network includes a plurality of blockchain nodes, and any blockchain node can correspond to at least one blockchain, and any blockchain can include at least one block.
In the prior art, blockchain applications can be divided into two categories: public chains: all nodes can participate in consensus and competitive accounting rights. The public chain is directed to the public, and any individual or group can read and send the transaction, and the transaction can obtain the effective confirmation of the blockchain and participate in the consensus blockchain. And (6) disclosing data. The method is characterized in that: neutral, open, slow transaction speed, need of 'mining' or similar consensus methods, commonly used P2P network, high censorship resistance. And (3) a permission chain: only the allowed nodes can agree on, compete for billing rights and create blocks, including all non-public chains, such as private, federation, enterprise, etc. The data may or may not be disclosed. The private chain is a block chain with writing authority in an organization hand; a federation chain refers to a chain of blocks controlled by several people or organizations, corporations, governments. The characteristics of the permission chain are: the transaction speed is high, the whole network consensus of the mining class is not needed, and the transaction cost is low (the transaction only needs to be verified by a plurality of allowed nodes); can be examined and can occupy the mainstream of the commercial application field.
As an emerging technology, the block chain technology has two main problems: 1) "decentralized" of the core value of the blockchain requires as many blockchain nodes as possible to run the full data node, but as the amount of blockchain data increases, the time consumed by sharing data and consensus also increases, thereby causing storage burden to the block, and more nodes will not run the full data node. 2) Processing transactions on a chain, given the numerous blockchain nodes, tends to cause blockchain network congestion when there is a consensus demand.

Example 1
An embodiment of a block chain-based financial data management method of the present invention is described below with reference to fig. 1 to 4.
FIG. 1 is a flow chart of an example of a blockchain-based financial data management method of the present invention.
As shown in fig. 1, a financial data management method includes the following steps.
Step S101, the management node acquires user data and stores the user data as block data to a block chain in an encrypted manner.
Step S102, the management node broadcasts the updated tile data to all other nodes of the blockchain network.
Step S103, the query node acquires updated tile data from the tile chain network to update the local tile chain, determines whether to accept a user in the updated tile data according to the updated tile data, calculates, for the accepted user, offer information for the user, and sends the offer information to the management node.
Fig. 2 is a block diagram of an example of an application scenario to which the blockchain-based financial data management method of the present invention is applied.
As shown in fig. 2, the financial data management method of the present invention is applied to a blockchain network, where the blockchain network is a P2P (Peer-to-Peer) network, the blockchain network includes a management node and a query node, and the blockchain is formed by orderly linking a plurality of data blocks. In this example, a plurality of financial institutions join the network by authorization and form a benefit-related federation with third-party authorities corresponding to the query node and the third-party authorities corresponding to the management node. The inventor of the invention improves the financial data management method based on the block chain technology, and concretely relates to the following steps.
First, in step S101, the management node acquires user data and stores the user data as tile data encrypted to the tile chain.
Specifically, a plurality of financial institutions federate with a management organization, and the management node acquires user data from each financial institution federated with the management organization and stores the user data as block data in a block chain in an encrypted manner.
In this example, the block chain is a federation chain and is formed by orderly linking a plurality of data blocks, each data block including user data, data recording information, and a timestamp.
In particular, the user data includes user attribute data, user financial data, and user tag data.
Further, the management node obtains user attribute data and user financial data, and the management node generates user tag data according to the user attribute data and the user financial data.
Next, in step S102, the management node broadcasts the updated tile data to all other nodes of the blockchain network.
In this example, after a management node or a query node creates a new data block, other nodes of the federation (i.e., all other nodes of the blockchain network) are notified in a broadcast manner, and data transmission and service implementation are performed directly between the nodes without intervention of an intermediate link or a centralized server (see fig. 3 in particular), so that various data are stored through the blockchain, and the security of the data can be ensured.
Preferably, the number of data updates is set within a predetermined time period, and the management node generates new block data each time the data is updated.
It should be noted that the above description is only given by way of example, and the present invention is not limited thereto.
Next, in step S103, the query node acquires updated tile data from the tile chain network to update the local tile chain, determines whether to accept a user in the updated tile data according to the updated tile data, calculates, for the accepted user, offer information for the user, and sends the offer information to the management node.
Specifically, upon or after receiving the broadcast notification, each financial institution obtains updated block data or the latest block data from the corresponding query node through authorization from the blockchain network.
In this example, each querying node may obtain user data in the updated block data only if user authorization is obtained.
Further, the query node judges whether to accept the user in the block data according to the user tag data in the updated block data.
In another example, as shown in fig. 4, the method of the present invention further includes a step S401 of determining whether the user is a target user of the financial institution (i.e., the step S103 is divided into two steps S103 and S401).
In step S401, the financial institution determines whether to accept the user in the block data, in other words, determines whether to be a target user of the financial institution, according to a preset determination rule and the read user tag data.
And under the condition that the user is the target user of the financial institution, receiving the user in the block data, and further acquiring user attribute data and user financial data in the block data.
Further, the query node is also used to calculate offer information for the user (i.e., the target user). Specifically, the financial institution calculates quote information for the user (i.e., the target user) based on the acquired user attribute data and the user financial data.
For example, the financial institution 1 judges that the user a is a target user of the institution, and calculates the offer information 1 for the target product a of the user a.
Similarly, the financial institutions 2 and 3 each determine that the user a is the target user, and calculate the offer information 2 and 3 for the target product a of the user a.
Further, the inquiry node 1, the inquiry node 2 and the inquiry node 3 receive quote information of the financial institutions 1, 2 and 3 for the target product a.
In this example, the target product a is referred to as a loan product. The quoted price information of the target product a refers to the loan interest rate, the loan amount and the like.
In this example, each query node sends the offer information for the target product a to the corresponding management node, and the management node accepts the offer information sent by each query node and provides the offer information list to the user a according to the user request.
Preferably, the management node sorts the quote information sent by each inquiry node and provides the sorted quote information to the user, in other words, the management node comprehensively manages all the quote information and participates in the bid ranking of the user product list so as to enable the user to select the optimal pricing financial institution.
Further, the rank of the offer information of the target product a is determined by calculation through a ranking model, for example, an FM algorithm model, a bilinear FFM, a DeepFFM model, a logistic regression, a gradient lifting tree (GBDT), and other algorithm models. The foregoing examples are provided for the purpose of illustration only and are not to be construed as limiting the present invention.
In addition, when the target user is not judged to be the financial institution, the user in the block data is not accepted, and further user data does not need to be acquired, so that the target user can be screened more effectively and more accurately.
In this embodiment, the target product is a loan product. The quotation information of the target product refers to the loan interest rate, the loan amount and the like. The present invention is not limited to the above description, which is given as an example and should not be construed as limiting the present invention.
It should be noted that, in other examples, the above step may also be split into two steps, for example, the step S103 is split into two steps (S103 and S401) or three steps. The foregoing is described by way of preferred examples only and is not to be construed as limiting the invention.
Compared with the prior art, the financial data management method comprehensively manages the user data, the financial data and the like of each financial institution through the block chain technology, can more effectively manage the financial data, and can improve the safety of the data; each financial institution can more accurately screen the target user, acquire the user data of the target user, provide the quotation information corresponding to the user data, and the management institution comprehensively manages all the quotation information and participates in the bidding and ranking of the user product list, so that the user can select the optimal pricing financial institution.
