Asset securitization management system and method based on blockchain

Abstract

The invention relates to an asset securitization management system and method based on a blockchain, and the system comprises an alliance chain which consists of four types of role participants: an original equity person, an intermediary mechanism, a supervision mechanism and an investor, and the four types of role participants respectively have respective account books. Data recorded in account books of the four types of role participants are kept consistent, the four types of role participants are connected with a consensus service network, and the consensus service network performs identityauthentication on each role participant according to the certificate trust chain; and the control module is used for performing node election, account book data consistency verification and data synchronization control on the four role participants so as to ensure that the account book data of the four role participants is consistent. Compared with the prior art, by constructing the distributed system, the basic asset information and the project operation information are synchronously uploaded in the whole process, the whole-network real-time sharing of the data is realized, the uploaded datacan be tracked and audited and cannot be randomly tampered, and the credibility of the data subsequently acquired by a user is also ensured.

Description

technical field [0001] The present invention relates to the technical field of block chains, in particular to a block chain-based asset securitization management system and method. Background technique [0002] Specifically, asset securitization is to package and reorganize a group of assets with poor liquidity through special-purpose vehicles, so that the asset portfolio can generate relatively stable cash flow in the foreseeable future, and on this basis improve credit enhancement. Its credit quality or rating, and finally the technology and process of converting expected cash flow into securities products that can be issued, sold, and circulated in the financial market. Asset-backed securities (Asset-Backed Securities, ABS) is a kind of securities that use the future cash flow of a certain type of specific assets with high value as the source of payment of principal and interest of securities. [0003] As a financial tool with rich connotations and multiple functions, as...

AI Technical Summary

Problems solved by technology

First, the high cost of issuance

The operating data of the underlying assets during the issuance period and the duration period are all owned by the original rights holders and are not disclosed to the public, resulting in information asymmetry

Although the due diligence conducted by intermediaries during the issuance period and the management reports regularly disclosed by the managers during the duration period can reduce the degree of information asymmetry, the formation data and historical operation data of the underlying assets are unilaterally provided by the original stakeholders, and their authenticity is still not available. ensure

The management report is only cross-sectional data with a fixed time frequency, which cannot realize the dynamic disclosure of the underlying assets; and the statistical dimension and disclosure degree of the management report are limited, which still cannot meet the requirements of investors, managers and rating agencies

The information asymmetry between original stakeholders, investors and intermediaries makes it difficult to accurately assess credit risk, leading to an increase in the issuance rate of ABS products, thereby increasing the issuance cost of original stakeholders

Second, the issuance efficiency is low

Due diligence, valuation and pricing, cash flow analysis and other links in the issuance period, as well as income accounting and distribution, asset service report disclosure and other links in the duration period involve a lot of information, and there are often situations of repeated provision and verification, resulting in low operational efficiency

Moreover, most of the data is transmitted through an external network disk, and there is a risk of information leakage

Third, the release cycle is long

Fourth, supervision is difficult

[0006] First, data is easily tampered with

The centralized management system is deployed locally in the participating institutions, and each participating institution has the highest maintenance authority for the data, and the data may be tampered with, so the authenticity of the data cannot be guaranteed

[0007] Second, poor synergy

Due diligence, product design, regulatory approval and many other business links that require the cooperation of multiple parties are still handled manually offline. The synergy effect of all parties is poor, and there are still problems of low efficiency and long cycle time.

[0008] Third, information security risks

Important data generated during the ABS business process, especially sensitive information such as basic assets, is transmitted through channels such as emails, U disks, and third-party network disks in the above scheme, and there is a serious risk of information leakage

[0009] Fourth, supervision is difficult

[0011] First, data can be tampered with

A single host organization needs to establish a centralized system, which has the highest maintenance authority for the data stored locally, and the data may still be tampered with, and the authenticity cannot be guaranteed

[0012] Second, it is difficult for the parties involved to trust each other

The main body of the centralized system may have insufficient credit. Whether the main body will leak data cannot be guaranteed, and it is difficult to gain the trust of all participants in the market. Therefore, the centralized system cannot be widely promoted in the industry

[0013] Third, fault tolerance and anti-attack capabilities are poor

Limited by factors such as construction costs, it is difficult for a centralized system to achieve redundant design by increasing hardware resources, and its fault tolerance mainly depends on software redundancy, which has limited fault tolerance

Since the centralized system is deployed in one main body, once it is attacked by an external party, it is prone to downtime risk and the anti-attack ability is poor

[0014] Due to these problems in the existing technology, the credibility of the data obtained by subsequent users cannot be guaranteed, which is not conducive to the issuance of ABS
