Description
Technical Field
The invention relates to the field of real estate trust investment funds, in particular to a TOKENIZED REITS block chain asset management system.
Background
In recent decades, the real estate industry has a scene of great prosperity and great development in China, and along with the further development of the economic society of China, the real estate industry has been gradually digitalized, such as the asset securitization of real estate, wherein the asset securitization refers to the process of taking cash flow generated in the future of basic assets as repayment support, carrying out credit enhancement through structural design, and issuing asset support securities on the basis. It is a financing form that issues tradeable securities, supported by a particular portfolio or a particular cash flow. The asset securitization is only a narrow sense of asset securitization, and is an operation mode for converting assets with low standardization degree and poor liquidity into financial products with high standardization degree and good liquidity after being packaged. Since the national mortgage association of the united states of america issued the mortgage supporting security of property based on mortgage loan combination for the first time, the property securitization has gradually become a widely used financial innovation tool and has been rapidly developed since the first securitization transaction of property was completed.
REITs are special purpose marketing companies on the international market that directly own a combination of real estate project company equity. In China, REITS is a part of the securities market of assets, which is a multi-trillion market, and can effectively store the inventory of the assets and form virtuous circle; on one hand, more 'new fund' injection is provided for economic development of Chinese entities; on the other hand, the method provides 'alternative' securities investment varieties of traditional financial products such as stocks, bonds and the like for vast investors. The structure of China REITS is more complex than that of the international market, and the structure is divided into three levels: i) project companies that are loaded with base assets; ii) project cash flow based ABS (REITS-like); iii) investing in public fund for ABS.
The application of the block chain technology to REITS products is mainly shown in the following steps: 1. determining the right of the basic assets; 2. traceability (non-tamperable) of data and documents; 3. tokenize is one way to achieve standardization over a chain of blocks; 4. on the basis of the asset interest token, the intelligent contract can be better applied, and the business process is standardized; 5. the method comprises the steps of utilizing a block chain technology to realize operation from basic assets to similar REITs through an intelligent contract on the basis of the share tokenize of a basic asset project company, then managing the position holding of the public fund through the intelligent contract on the basis of the share tokenize of the similar REITs, and finally managing the share tokenize of the public fund. While the purpose of tokenize is to: 1. determining the share; 2. share trading; 3. standardization (information disclosure, clearing, revenue distribution, trading); 4. and (6) docking the intelligent contract.

All data interaction and information sharing after uplink are recorded by the account book module, and the data can be only added, and cannot be modified or deleted, so that the traceability of the account book data is guaranteed.
The transaction chain in the prior art is long, cash flow distribution is complex, manual reconciliation efficiency is low, error rate is high, occurrence of default or other triggering events caused by increase of the deposit period management work influences security repayment and subsequent asset processing, and uncertain factors which can not be repayed according to contracts exist; according to the securities repayment rule of the contract clauses, the rule is added into the intelligent contract in the intelligent contract module, and no matter how complex the distribution is, the efficient, correct and automatic repayment of each repayment date can be guaranteed, the efficiency is improved, and the post-delivery management work is simplified; if default or other trigger events occur, the intelligent contract automatically executes the distribution, transaction or clearing of assets according to the terms agreed in advance, so that the management cost is reduced, and uncertain factors are reduced.
The basic assets in the prior art are not sold really, the real existence of the assets cannot be guaranteed, the credit risk exists, the assets are opaque, particularly, the securitization rating of the assets of a trading exchange depends on the credit of a main body instead of the original rights beneficiary of the assets, and other organizations cannot obtain real, complete and timely asset information; the method and the system have the advantages that the right of the assets is confirmed by using a block chain technology, real selling of the assets is replaced by a technical means, and meanwhile real existence of the assets on the chain is guaranteed. Meanwhile, after the assets are linked, different participating mechanisms realize data sharing, and a traditional asset evaluation mode is broken through, so that the asset evaluation is more objective, and the risk caused by centralization is reduced; after the basic assets are linked, the asset information is transparent and complete and can be transmitted to each node in time, the credit is added to the basic assets, and the securities rating does not depend on the rating of an issuing main body excessively; a virtual independent asset facilitator may be placed on the blockchain.
Therefore, the invention has the advantages that:
1. standardizing the key steps of the real estate REITS through tokenization on a block chain;
2. the laws, regulations and transaction modes of REITs of China public recruitment are likely to be continuously improved and improved, and the technical framework behind tokenize is still established;
tokenization may also promote international development of the china REITs market. The token of the project company can be directly connected with REITs in overseas, and the token of the public fund can be connected with the stock market in overseas, thus being convenient for trading and clearing.
In the description of the present invention, it is to be understood that the terms "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like, indicate orientations or positional relationships based on those shown in the drawings, are merely for convenience of description of the present invention, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.
The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and do not limit the scope of the present invention, and various modifications and improvements of the technical solutions of the present invention can be made by those skilled in the art without departing from the spirit of the present invention, and the technical solutions of the present invention are within the scope of the present invention defined by the claims.
