Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.

Common financing supporting modes of a supply chain financial platform include an upstream supplier account receivable financing mode and a downstream distributor order financing mode, and the financing modes provide wind control basis for platform operators and fund parties by means of credit of core enterprises and real transaction data of the core enterprises and the upstream enterprises. As shown in fig. 1a, fig. 1a illustrates a framework of a block chain based supply chain financial platform, with participants of the platform mainly including a core enterprise, upstream supply chain and downstream distributors of the core enterprise, and platform operators. The platform supports multiple core enterprises and supplier, dealer, and funder enrollment around the core enterprises. The supply chain financial service platform provides a Web webpage console based on an HTTPS protocol for core enterprises, capital parties, suppliers and dealers, all parties can submit data, execute approval operation and sign electronic contracts on line on the webpage console, and the key data, operation records and electronic contracts are electronically signed by corresponding executing parties and then recorded and stored on a blockchain. The supply chain financial platform is a business layer platform, and the underlying block chain is managed by a BaaS (block chain as a service) platform. The BaaS platform can perform the work of establishing and deploying a bottom layer block chain, treating a coalition, managing an account book, setting access authority, monitoring the operation state of block chain link points, expanding a block chain network and the like.

In order to save the use cost of each participant, the blockchain network only consists of blockchain link points of a platform operator, a supervisor and a credit-increase party together, and other participants such as core enterprises, capital parties, suppliers and dealers do not deploy independent blockchain nodes.

FIG. 1b shows the flow of the receivables financing service, and FIG. 1c shows the flow of the order financing service. Every transaction on the platform will have core enterprises, platform operators and funders as the main participants.

Because the platform is provided with a plurality of core enterprises and fund parties providing financing services, the information of transaction prices, fund prices, suppliers and the like of the core enterprises and the fund parties is very sensitive, and the information of each core enterprise and each fund party can only be read by business participants needing to know but cannot be obtained by other unrelated core enterprises or fund parties and the like. Privacy security of data is very important.

Each core enterprise can have a plurality of fund parties to provide services, and the number of platform operators is only 1. Participants in each business portfolio < core enterprise, platform operator, funder > can share data in the group, but cannot let other portfolios see the data in the group. For example, core enterprise a has two funding parties B and C servicing it, then there are two business combinations for core enterprise a: < core enterprise a, platform operator, funder B > and < core enterprise a, platform operator, funder C >. Because both core enterprise a and the platform operator are in both combinations, the core enterprise a and the platform operator can see the data in both combinations. The data between the two combinations should be isolated from each other, so that the data of the other party cannot be seen by the fund party C and the fund party B. However, the traditional block chain has only one account book, if the above data privacy problem needs to be satisfied, data of all core enterprises and capital parties have to be recorded on the same account book, and the access authority of each participant to the account book is controlled by an upper supply chain financial service platform, which is easily to cause sensitive data leakage due to errors of a service platform logic program. If a blockchain is deployed independently for a supply chain around a core enterprise, many blockchains and a large number of blockchain nodes need to be deployed, and the use cost of the blockchain is increased. In order to solve the above problem, an embodiment of the present invention provides a financial data processing method based on a block chain.

Example one

Fig. 2a is a flowchart of a method for processing financial data based on a blockchain according to an embodiment of the present invention, where the embodiment is applicable to a case of financial data processing, and the method may be executed by a blockchain-based financial data processing apparatus, which may be composed of hardware and/or software and may be generally integrated in a device having a blockchain-based financial data processing function, where the device may be an electronic device such as a server or a server cluster.

As shown in fig. 2a, the method specifically includes the following steps:

and step 110, when the core enterprise node initiates a new financial service request to the supply chain financial platform, determining the block link points participating in the current service according to the financial service request.

The block link point participating in the current service may include: a core enterprise node, a funder node, and a platform operator node. The financial service request carries information of the block link nodes participating in the current financial service and service information.

In this embodiment, the core enterprise may initiate a financing service request, the funder is used to provide funding, and the platform operator is used to manage the execution of the whole financing service process.

Specifically, when a core enterprise needs to initiate a new financing service, a new financial service request is initiated to the supply chain financial platform, so that the supply chain financial platform determines the block link points participating in the current service according to the financial service request. Illustratively, the core enterprise a initiates a new financial service request, and the financial service request carries other block chain nodes participating in the service, namely the core enterprise b, the funder c and the platform operator.

In this embodiment, the core enterprise node initiates a new financial service request to the supply chain financial platform, which may specifically be understood as: the core enterprise node initiates a request for adding a new fund side node to a supply chain financial platform; judging whether the new capital side node, the core enterprise node and the platform operator node are a new service group or not; if the business group is new, the core enterprise node initiates a new financial business request to the supply chain financial platform.

Specifically, when a core enterprise node initiates a new financial service request to the supply chain financial platform, the core enterprise node, the funder node, and the platform operator node participating in the current service may be determined according to the financial service request.

The manner of determining whether the new fund party node, the core enterprise node and the platform operator node are the new service group may be: and the core enterprise node acquires a service group corresponding to each public sub-account book by accessing the public sub-account book deployed locally, and if the service group formed by the new fund party node, the core enterprise node and the platform operator node is different from the existing service group, the service group is a new service group, otherwise, the service group is not a new service group.

For example, the existing fund party B provides financing service for the core enterprise a, and the core enterprise a, the platform operator and the fund party B form a business group to develop supply chain financial business. Due to business needs, a new fund party C needs to be added to provide financing service for a core enterprise A, a core enterprise A node initiates a request for adding the new fund party C node to a supply chain financial platform, and the core enterprise A, a platform operator and the fund party C form a new business group after judgment, so that the core enterprise A node initiates a new financial business request to the supply chain financial platform. According to the financial service request, a core enterprise A node, a capital side C node and a platform operator node which participate in the current service can be determined.

And step 120, the supply chain financial platform sends a linkage control instruction to the block chain platform according to the new financial service request.

The linkage control instruction can be specifically understood as an instruction for requiring the BaaS platform to create a new public sub account book on the underlying area block chain, and the supply chain financial platform and the BaaS platform of the area block chain are in interface butt joint, so that the linkage control instruction can be automatically sent to the BaaS platform according to the service requirement. Illustratively, the instructions may be implemented as a command line program.

Specifically, the supply chain financial platform sends an instruction for requiring the BaaS platform to create a new public sub-ledger on the underlying blockchain to the blockchain platform according to a new financial service request, that is, a formed new service group (core enterprise, funder and platform operator).

And step 130, the block chain platform creates a new public sub account book according to the linkage control instruction, and determines the access authority of the new public sub account book according to the block chain link points participating in the current service.

The access authority comprises a read-only authority or a read-write authority, and the block chain platform gives the block chain link points participating in the current service the authority of only reading the new public sub-account book or reading and writing the new public sub-account book. Wherein, the access right can be agreed by each block link point participating in the current service.

Specifically, the block chain platform can dynamically create a new public sub-account book on the same block chain according to the linkage control instruction, and the new public sub-account book is isolated from other public sub-account book data. Meanwhile, each public sub-account book can independently set different visitor sets and corresponding authority control. Each blockchain node can join a plurality of public sub accounts simultaneously. If a block link point does not join a common sub-ledger, then the node cannot access the data in the ledger.

Optionally, after determining the access right of the new common sub-ledger according to the block link point participating in the current service, the method further includes: and the blockchain platform returns the access identification code of the new public sub-ledger to the supply chain financial platform.

Specifically, the access identification code may be understood as Identity Information (ID) of the public sub-ledger, and each public sub-ledger has a unique access identification code for verifying whether each block link point has access right to the public sub-ledger. The access identification code may be formed according to a preset rule, where the form of the access identification code is not limited, for example, the access identification code may be a string of characters formed according to the rule, or may be a hash value obtained by a hash operation.

In step 140, the blockchain platform deploys the new public sub-ledger at each blockchain node participating in the current service.

The block chain platform can deploy the new public sub-ledger to each block chain node participating in the current service in a distributed deployment mode. Specifically, the blockchain platform deploys the new public sub-ledger at each blockchain node participating in the current service. Illustratively, a new public sub-ledger 1 is created according to a service combination of < core enterprise a, platform operator, and funder B >, and then the public sub-ledger 1 is deployed at a core enterprise a node, a platform operator node, and a funder B node.

And 150, accessing the financial data corresponding to the new public sub-account book by each block link point participating in the current business according to the access authority.

The mode of accessing the financial data corresponding to the new public sub-ledger can be as follows: and reading financial data in the public sub-ledger or writing the financial data into the public sub-ledger. If the access authority of a certain block link point to the public sub account book is read only, the block link point can only read financial data in the public sub account book, but cannot write the financial data into the public sub account book; if the access authority of a certain block link point to the public sub account book is read-write, the block link point can read financial data in the public sub account book and write the financial data into the public sub account book.

Specifically, each block link point participating in the current service acquires a service identifier to be processed; determining an access identification code according to the service identifier; determining a target public sub-ledger according to the access identification code; and accessing the financial data corresponding to the target public sub-account book according to the access authority.

When the supply chain financial platform needs to upload data related to business combination to a block chain or needs to read data on a public sub-ledger, firstly, an access identification code is determined according to the related business identification, then, the public sub-ledger to be accessed is determined according to the access identification code, and finally, related data is recorded on a new public sub-ledger or data is read from the public sub-ledger.

For example, the method for processing financial data based on a blockchain according to the present embodiment is described as an example below, and fig. 2b is a schematic diagram of division of a public sub-ledger. As shown in fig. 2 b: there are two core enterprises on the platform: core enterprise A and core enterprise D; two fund parties: funder B and funder C. Core enterprise a is financing services provided by financer B and financer C simultaneously, and core enterprise D is financing services provided by financer C only. According to the business division, three business groups of < core enterprise a, platform operator, fund B >, < core enterprise a, platform operator, fund C > and < core enterprise D, platform operator, fund C > are formed, so that the supply chain financial platform gives an instruction to the BaaS platform to create three public sub-accounts as shown in fig. 2B. Data among the three public sub-accounts are isolated, each sub-account can only be accessed by the business group participant, wherein the public sub-account 1 can be accessed by a core enterprise A, a platform operator and a fund party B; the sub account book 2 can be accessed by a core enterprise A, a platform operator and a fund party C; sub-ledger 3 may be accessible by core enterprise D, platform operator, funder C.

The technical scheme of the embodiment includes: when a core enterprise node initiates a new financial service request to a supply chain financial platform, determining block link points participating in the current service according to the financial service request; the supply chain financial platform sends a linkage control instruction to the block chain platform according to the new financial service request; the block chain platform creates a new public sub account book according to the linkage control instruction, and determines the access authority of the new public sub account book according to the block chain link points participating in the current business; the block chain platform deploys the new public sub-account book to each block chain node participating in the current business; and each block chain link point participating in the current business accesses the financial data corresponding to the new public sub-account book according to the access authority, an independent public sub-account book is created by adopting a block chain platform according to the linkage control instruction, and the access authority is set so as to be isolated from other public sub-account books, so that the privacy problem of the financial data can be solved, and the safety of the financial data is improved.
