技术领域Technical field
本发明涉及金融数据分析处理领域,具体而言,涉及一种用于金融数据共享的方法、装置及电子设备、计算机可读介质。The present invention relates to the field of financial data analysis and processing, and in particular to a method and apparatus for financial data sharing, and an electronic device and a computer readable medium.
背景技术Background technique
资产支持证券(ABS)是指以基础资产未来可产生的稳定现金流为支撑,通过标准化产品设计进行信用增级,在此基础上发行证券的金融活动。资产证券化业务自从2014年从审核制改备案制以后,市场快速增长,目前已达到近2万亿的存量规模。资产按证券化业务可以充分优化金融机构资产结构,降低金融市场系统风险,释放金融机构的贷款规模,提高其资本充足率,并在改善金融机构的盈利模式和加速其业务转型方面带来很大的帮助。资产证券化金融产品,以其标准的产品结构和发行流程,结构化的金融产品设计,为消费金融业务的融资开辟了另一渠道。通过标准化的ABS产品,利用批量发行进行融资,互联网消费金融机构可以充分的降低融资成本,盘活存量资产,支持业务持续发展。据估计,资产证券化融资能将消费金融公司的整体融资成本下降1-3个百分点。Asset-backed securities (ABS) refers to financial activities in which securities are issued on the basis of standardized product design for credit enhancement, supported by stable cash flows generated by the underlying assets in the future. Since the asset securitization business has been in the market since 2014, the market has grown rapidly and has reached a stock scale of nearly 2 trillion. The asset-based securitization business can fully optimize the financial institution's asset structure, reduce the financial market system risk, release the financial institution's loan scale, increase its capital adequacy ratio, and bring great benefits in improving the financial institution's profit model and accelerating its business transformation. s help. Asset securitization financial products, with its standard product structure and issuance process, structured financial product design, opened up another channel for the financing of consumer finance business. Through standardized ABS products and financing through batch issuance, Internet consumer financial institutions can fully reduce financing costs, revitalize existing assets, and support business continuity. It is estimated that asset securitization financing can reduce the overall financing cost of consumer finance companies by 1-3 percentage points.
从业务本身的角度出发,目前大部分互联网消费金融公司虽然具有场景优势,但其所发行的ABS资产仍面临与资金端对接的困难,整个市场对此类ABS仍存在“看不清”,“管不住”等问题。其中,痛点主要体现在三个方面:From the perspective of the business itself, most Internet consumer finance companies have the advantage of the scene, but the ABS assets they issue still face difficulties in docking with the funds. The whole market still has “invisible” for such ABS, “ Can't help but ask questions. Among them, the pain points are mainly reflected in three aspects:
1、底层资产的真假无法保证1. The true and false of the underlying assets cannot be guaranteed.
2、如果消费金融公司本身出了问题,没人来解决借款人偿还的后续问题。2. If the consumer finance company itself has a problem, no one will solve the follow-up problem of the borrower's repayment.
3、资产证券化产品呈现出结构复杂,参与主体多,操作环节多,数据传递链条长,数据及现金流分配过程繁复等特征,投资人和中介机构难以穿透底层把握风险。3. Asset securitization products are characterized by complex structure, multiple participants, many operational links, long data transmission chains, and complicated data and cash flow distribution processes. It is difficult for investors and intermediaries to penetrate the bottom to grasp risks.
这三大痛点,决定了互联网消费金融公司虽有很强的资产生产能力,却很难得到低成本资金方的认可,所以只能选择成本较高的资金来源,因而限制了发展。These three pain points have determined that although Internet consumer finance companies have strong asset production capacity, they are difficult to obtain recognition from low-cost funds. Therefore, they can only choose a higher-cost source of funds, thus limiting development.
因此,需要一种新的用于金融数据共享的方法、装置及电子设备。Therefore, there is a need for a new method, apparatus, and electronic device for financial data sharing.
在所述背景技术部分公开的上述信息仅用于加强对本发明的背景的理解,因此它可以包括不构成对本领域普通技术人员已知的现有技术的信息。The above information disclosed in the Background section is only for enhancement of understanding of the background of the invention, and thus it may include information that does not constitute the prior art known to those of ordinary skill in the art.

下面结合附图对本公开示例实施方式进行详细说明。The exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.
图1是根据一示例性实施例示出的一种用于金融数据共享的方法的流程图。FIG. 1 is a flow chart showing a method for financial data sharing, according to an exemplary embodiment.
如图1所示,在S102中,根据金融资产数据生成第一区块数据。金融资产数据可例如为来自资产方的资产相关数据。资产方代表的是企业所有的资产包括固定资产、流动资产、无形资产。根据上文介绍,资产方可以将资产进行金融证券化相关处理。资产方可以根据其金融资产数据,生成第一区块数据。还可例如,将金融数据进行预定的封装处理,进而生成第一区块数据。预定的封装处理可例如包括:按照预定义的第一交易字段封装所述金融资产数据,以生成第一封装数据;指明第一处理公钥;指明第一交易事件;对所述第一封装数据、所述第一处理公钥以及第一交易事件进行签名认证,生成第一区块数据。As shown in FIG. 1, in S102, first block data is generated based on the financial asset data. The financial asset data can be, for example, asset related data from the asset side. The asset side represents the assets owned by the enterprise, including fixed assets, current assets, and intangible assets. According to the above, the asset side can process the asset for financial securitization. The asset side can generate the first block data based on its financial asset data. For example, the financial data may be subjected to predetermined encapsulation processing to generate first block data. The predetermined encapsulation process may, for example, comprise: encapsulating the financial asset data according to a predefined first transaction field to generate first encapsulation data; indicating a first processing public key; indicating a first transaction event; and the first encapsulation data And the first processing public key and the first transaction event perform signature verification to generate first block data.
在S104中,根据第一区块数据以及审核数据生成第二区块数据。可例如,资金方根据第一区块数据进行资产审核,可例如,审核贷款单、还款计划、金融资产本身的审核等等,审核之后生成审核数据。还可例如,将第一区块数据与所述审核数据一同进行封装,并指明公钥以及下一步交易事件等操作后,签名认证生成第二区块数据。In S104, second block data is generated based on the first block data and the audit data. For example, the funder may conduct an asset review based on the first block data, for example, reviewing the loan slip, the repayment plan, the audit of the financial asset itself, and the like, and generating audit data after the audit. For example, after the first block data is encapsulated together with the audit data, and the public key and the next transaction event are specified, the signature authentication generates the second block data.
在S106中,根据第二区块数据以及支付数据生成第三区块数据。可例如,负责进行金融支付的支付通道方根据第二区块数据进行放款操作,放款操作后生成支付数据,将第二区块数据以及支付数据进行封装,并指明各种相关公钥以及交易事件等操作后,经过签名认证生成第三区块数据。In S106, third block data is generated based on the second block data and the payment data. For example, the payment channel that is responsible for the financial payment performs the lending operation according to the second block data, generates the payment data after the lending operation, encapsulates the second block data and the payment data, and indicates various related public keys and transaction events. After the operation, the third block data is generated through signature verification.
在S108中,将所述第三区块数据进行发布以完成金融数据链码部署。可例如,将第三区块数据广播到金融系统中,以完成链码部署。还可例如,将第三区块数据进行发布以完成金融数据的联盟链的链码部署。In S108, the third block data is published to complete the financial data chain code deployment. For example, the third block data can be broadcast to the financial system to complete the chain code deployment. It is also possible, for example, to publish the third block data to complete the chain code deployment of the federated chain of financial data.
根据本发明的用于金融数据共享的方法,通过将金融数据进行链码部署的方式,利用区块链去中心化,防篡改以及分布式账本的特性来进行数据保真,一旦入链之后将无法由单方私自纂改,能够保证资产证券化服务商底层数据的真实性。According to the method for financial data sharing of the present invention, data security is performed by using a chain chain decentralization, tamper resistance, and distributed account book characteristics by way of chain code deployment, once the chain is entered, It cannot be tamed by a single party and can guarantee the authenticity of the underlying data of the asset securitization service provider.
应清楚地理解,本发明描述了如何形成和使用特定示例,但本发明的原理不限于这些示例的任何细节。相反,基于本发明公开的内容的教导,这些原理能够应用于许多其它实 施例。It will be clearly understood that the present invention describes how to make and use particular examples, but the principles of the invention are not limited to the details of the examples. Rather, these principles can be applied to many other embodiments based on the teachings of the present disclosure.
在本公开的一种示例性实施例中,所述将所述第三区块数据进行发布以完成金融数据链码部署,包括:所述将所述第三区块数据进行发布以完成金融数据的联盟链的链码部署。In an exemplary embodiment of the present disclosure, the publishing the third block data to complete the financial data chain code deployment comprises: publishing the third block data to complete financial data The chain code deployment of the alliance chain.
区块链本质上是几种技术方案的统称,包括点对点的对等网络传输协议,密码学加密算法,分布式的共识机制,以及纳什均衡的博弈设计。基于这几种技术的结合,可以实现去中心化去信任的可靠数据库,使用算法证明机制来保证链上所记录信息的可追踪溯源,不可伪造,不可纂改。联盟区块链是指其共识过程受到预选节点控制的区块链;例如,不妨想象一个有15个金融机构组成的共同体,每个机构都运行着一个节点,而且为了使每个区块生效需要获得其中10个机构的确认(2/3确认)。区块链或许允许每个人都可读取,或者只受限于参与者,或走混合型路线,例如区块的根哈希及其API(应用程序接口)对外公开,API可允许外界用来作有限次数的查询和获取区块链状态的信息。这些区块链可视为“部分去中心化”。联盟链采用多中心方式,参与方节点也是事先所设定,通过共识机制确认。在联盟链中,区别于公有有链,可以进行权限设定和控制,拥有更高的可应用和可扩展性。The blockchain is essentially a collective term for several technical solutions, including peer-to-peer peer-to-peer network transport protocols, cryptographic encryption algorithms, distributed consensus mechanisms, and Nash equilibrium game design. Based on the combination of these technologies, a reliable database of decentralization and trust can be realized, and an algorithmic proof mechanism is used to ensure traceable traceability of information recorded on the chain, which cannot be forged and cannot be tampered with. The alliance blockchain refers to the blockchain whose consensus process is controlled by pre-selected nodes; for example, imagine a community of 15 financial institutions, each of which runs a node, and in order to make each block effective Obtained confirmation from 10 of them (2/3 confirmation). The blockchain may allow everyone to read, or be restricted to participants, or take a hybrid route, such as the root hash of the block and its API (application programming interface), the API allows the outside world to be used Make a limited number of queries and get information about the status of the blockchain. These blockchains can be thought of as "partial decentralization." The alliance chain adopts a multi-center approach, and the participant nodes are also set in advance and confirmed by a consensus mechanism. In the alliance chain, different from the public chain, you can set and control permissions, and have higher applicability and scalability.
根据一些实施例,还可例如,在本实施例中,部署多个验证点,可例如为4个验证节点,资产方,资金方,以及资金通道方各掌握一把私钥,每个验证节点本地(或者云端)都部署了一套分布式账本数据库。区块链管理系统中每笔交易的产生都需要所有节点达成共识后才能入链。According to some embodiments, for example, in the embodiment, multiple verification points are deployed, for example, four verification nodes, an asset side, a fund side, and a money channel side each have a private key, and each verification node A distributed set of ledger databases is deployed locally (or in the cloud). Each transaction in the blockchain management system requires all nodes to reach a consensus before they can be chained.
根据本发明的用于金融数据共享的方法,通过将金融数据进行联盟链链码部署的方式,能够大幅降低异地的读写成本和时间,能提供更简单,效率更高的共识服务,同时继承去中心化的优点,减轻垄断压力。According to the method for financial data sharing of the present invention, by deploying the financial data in the chain code of the alliance chain, the cost and time of reading and writing in different places can be greatly reduced, and the simpler and more efficient consensus service can be provided, and the inheritance can be realized. The advantages of decentralization reduce the pressure of monopoly.
在本公开的一种示例性实施例中,所述第一区块数据、所述第二区块数据以及所述第三区块数据之间通过共识算法进行共识机制确认。在本公开的一种示例性实施例中,所述共识算法包括:拜占庭容错算法。In an exemplary embodiment of the present disclosure, the first block data, the second block data, and the third block data are confirmed by a consensus mechanism by a consensus algorithm. In an exemplary embodiment of the present disclosure, the consensus algorithm includes: a Byzantine fault tolerance algorithm.
PBFT是Practical Byzantine Fault Tolerance的缩写,意为拜占庭容错算法。该算法是Miguel Castro(卡斯特罗)和Barbara Liskov(利斯科夫)在1999年提出来的,解决了原始拜占庭容错算法效率不高的问题。早期的拜占庭容错算法或者基于同步系统的假设,或者由于性能太低而不能在实际系统中运作。同时POW(Prove of Work)算法的确认速度太慢,同时需要消耗大量的资源。BFT算法的基本思路如下:Client会发送一系列请求给各个replicas节点来执行相应的操作,BFT算法保证所有正常的replicas节点执行相同序列的操作。因为所有的replicas节点都是deterministic,而且初始状态都相同,根据状态机原理(state machine replication),这些replicas会产生相同的结果状态。当Client收到f+1个replicas节点返回的结果时,如果这些结果都一样,因为BFT算法确保了最多有f个replicas出现问题,所以至少有一个replicas是正确的,那么Client收到的这些结果都是正确的。但是state machine replication的难点在于确保正常replicas节点都以相同的序列执 行同样的一些请求,尤其是如何来面对拜占庭故障。而PBFT这种利用副本复制(replication)的方法解决拜占庭容错问题,并可以让该算法工作在异步环境中,并且把响应性能提升了一个数量级以上。用这个算法实现了拜占庭容错的网络文件系统(NFS),性能测试证明了该系统仅比无副本复制的标准NFS慢了3%。PBFT is the abbreviation of Practical Byzantine Fault Tolerance, which means Byzantine fault-tolerant algorithm. The algorithm was proposed by Miguel Castro (Castro) and Barbara Liskov (Liskov) in 1999 to solve the problem of the inefficiency of the original Byzantine fault-tolerant algorithm. Early Byzantine fault-tolerant algorithms or assumptions based on synchronous systems, or because performance is too low to operate in real systems. At the same time, the POW (Prove of Work) algorithm is too slow to confirm and consumes a lot of resources. The basic idea of the BFT algorithm is as follows: The client sends a series of requests to each replicas node to perform the corresponding operations. The BFT algorithm ensures that all normal replicas nodes perform the same sequence of operations. Because all replicas are deterministic and have the same initial state, these replicas produce the same result state according to state machine replication. When the client receives the results returned by the f+1 replicas node, if the results are the same, because the BFT algorithm ensures that there are at most f replicas, at least one replica is correct, then the client receives the results. It is all right. But the difficulty with state machine replication is to ensure that normal replicas execute the same requests in the same sequence, especially how to deal with Byzantine failures. PBFT, which uses replica replication, solves the Byzantine fault tolerance problem and allows the algorithm to work in an asynchronous environment and improve response performance by more than an order of magnitude. Using this algorithm to implement the Byzantine Fault Tolerant Network File System (NFS), performance testing proves that the system is only 3% slower than the standard NFS without copy replication.
根据本发明的用于金融数据共享的方法,通过拜占庭容错算法将金融数据进行链码部署的方式,能够使得该金融数据共享的方法工作在异步模式下,而且加快了金融数据的处理速度。According to the method for financial data sharing of the present invention, the method of deploying financial data in a chain code by the Byzantine fault-tolerant algorithm enables the method of financial data sharing to work in an asynchronous mode and speed up the processing of financial data.
