step S8: after the bond life cycle is finished, the management node performs project clearing and returns the residual gain right of the project to the equity person node, and clearing information is signed by the nodes of the two parties and then is uplink.
It can be understood that the ABS bond issuing transaction method based on the blockchain of the present embodiment realizes the full uplink of the basic asset information, the corresponding payoff funds and account flow information are anchored with each basic asset one by one, and the irrevocable and unrepeatable transfer of the basic asset are guaranteed, and each participant of the project can know the real condition of the underlying asset in real time, thereby solving the problem of information asymmetry, promoting trust between each other, and based on this, the main credit rating and the project credit rating can be truly separated. Through the application of the blockchain technology, not only can the bottom layer assets meeting the standard be screened out rapidly and effectively and the preparation time of ABS projects be shortened, but also the upgrading of asset securitization to business models and the multidimensional linkage can be assisted, the liveness of capital markets is improved and the financial resource allocation efficiency is improved. Meanwhile, by utilizing the intelligent contract technology, third party supervision authorities such as auditing and rating parties are introduced, a brand new trust mechanism is constructed among the business participation roles of original rights and interests, management people, banks, sponsors and the like, so that the trust pain point in credit asset circulation is effectively solved, and the supervision authorities can timely and effectively grasp the bottom asset, thereby truly realizing penetration supervision.
It can be understood that in the step S1, the equity node signs the enterprise information, the financial information and the base asset information and then links the same, the supervision node performs an audit according to the linking information of the equity node, inquires about the company condition of the equity, and the audit is confirmed by the post-signature.

Related information provided by the rights and interests personnel is required to be endorsed after being checked by a supervision mechanism, so that the authenticity of the information is ensured, and the trust degree of each party node in the transaction process is improved. Meanwhile, the credit rating of the main body is independently rated by a credit rating agency and separated from the credit rating of the project, so that the credibility is further improved.
It will be appreciated that, as shown in fig. 2, the step S2 includes the following:
Step S21: the equity person node signs the financing information and then uploads the financing information to the blockchain, and delegates an asset SPV plan to the management node;
step S22: the management node surveys the real situation of the right and benefit person node after receiving the application, and performs signature uplink after giving out a due job investigation report;
Step S23: the management node and the equity person node draw project schemes, and the two nodes sign asset buying/selling protocols and process the project schemes through a blockchain privacy set technology and then are uplink.
The financing information comprises signature back-up links of financing requirements, expected financing scale, financing period, cost control, time requirements and the like. After receiving the application, the management node performs entrance adjustment, refers to the information authenticity of interviews, conferences and field investigation rights and interests, and after writing the investigation report of the due job, the management node links the report signature. The content of the project scheme comprises project elements, transaction structures, pooled base assets, time schedule, main transaction contract listing and the like, and after the two nodes sign, the information of the asset buying/selling protocol is processed through a blockchain privacy set technology and then is uplink.
It will be appreciated that, as shown in fig. 3, the step S3 includes the following;
Step S31: the management node submits security issuing and reporting materials to the security exchange node, and after the security exchange node verifies the public key of the management node, the on-chain equity person information and the reporting materials are compared and qualification checking is carried out, and the checking result is signed and then is uplink;
Step S32: the management node registers with the bond registration settlement node, and links the registration information signature, the bond registration settlement node verifies the public key of the management node and then examines the on-link security registration information in detail, and the result signature is linked after the examination is passed;
Step S33: the management node applies for a record to the node of the foundation association after the bond is issued, signs the record application information, and then links the record application information;
Step S34: the management node applies for a listing from the securities trade node after the bonds are issued, the securities trade node verifies the quotation application information on the chain, and the result signature is linked after the verification is passed.
The securities trading nodes hold a conference of a listing work group to determine whether the project passes or not, and sign voting results and then link the voting results to be supervised by the nodes of all parties. In addition, the management node needs to apply for the record and the application listing of the foundation association within 5 working days after the bond is issued.
It will be appreciated that step S4 includes the following:
The management node applies for the trust increasing measures to the guarantee node, the guarantee node verifies the public key of the management node and then compares the asset information of the chain equity person node with the guarantee contract carefully, and signature uplink is carried out after the confirmation is carried out.
The management node engages the financial consultant to further perfect the letter increasing measures (mainly comprising internal letter increasing and external letter increasing), applies the letter increasing measures to the guarantee node and links the signature, after the guarantee node verifies the public key of the management node, the asset information of the on-chain equity person node is carefully compared, the on-chain guarantee contract is checked in detail, and the guaranteed information is signed and linked after the guarantee is confirmed.
It will be appreciated that, as shown in fig. 4, the step S5 includes the following:
step S51: the management node sends a mark to the qualified underwriter node in a mark-signing mode, and signs the mark-signing information and then links the mark-signing information;
step S52: after the underwriter node marks the bid, the pricing information signature is linked and securities are sold;
step S53: the investor node verifies the public key of the equity person node, confirms the uplink basic asset information, negotiates price with the underwriter node, signs the bargained price information and then links the signed bargained price;
step S54: after verifying the public key of the investor node, the underwriter node discusses the transaction details with the investor node, and the underwriter node signs a subscription agreement and transfers the bond interests, signs the related information and links the related information;
step S55: the investor node pays the financing money to the supervision account of the equity person node, signs and then links the transfer information, and the equity person node confirms that the transfer information is signed and links after receiving the money.
The management node sends a bid to the qualified contractor nodes in a bid-bidding mode, bid-winning purchases of bidders correspond to investment purchases, and the information is signed and uplink. After bid is marked in the contractor node, pricing information is signed and linked up, and the price information is sold for the second time to the society. After verifying the public key of the equity node, the investor node confirms the uplink bottom layer asset information, negotiates price with the underwriter node, signs and links the bargained price information. After verifying the signature of the investor node, the underwriter node and the investor node discuss the transaction details, and the management node and the investor node sign the subscription agreement, transfer the bond rights and interests and link the related information signature. And then, the investor node pays the financing amount to the supervision account of the equity person node, and the transfer information signature is linked, and after receiving the amount, the equity person node confirms the collection information signature and links. The buying and selling process of the whole bond is performed in a transparent manner on the blockchain, and the information needs to be confirmed by the signature of the related node, so that the trust degree among transaction nodes of all parties is greatly improved.
In addition, in the step S5, pricing is performed based on the following formula:
The NPV is the net present value of the securitized asset in the period of n years, the asset estimation method is a CAPM model, C t is the net cash flow of the securitized asset in the t year, I is the initial investment of the securitized asset in the t year, t is the cash register, K is the cash register, the dynamic interest rate can be realized by using intelligent contracts on a blockchain, the fixed interest rate agreed by a protocol can also be adopted, R i is the expected return rate, R f is the risk-free interest rate, beta i is a systematic risk coefficient, and R M is the expected market return rate.
In addition, when the rights beneficiary node repays the loan in advance, the interest rate is designed by adopting the following method:
Determining a reference interest rate deadline structure of the current day from market prices of the current day free bonds, and constructing a interest rate volatility deadline structure according to historical information or the implicit volatility of the corresponding interest rate options (if the corresponding option market exists).
The dynamic change of the interest rate is described by using a proper random process, various possible paths of the future interest rate change are generated by adopting a proper simulation method, and the whole simulation process has the property of no arbitrage because the term structure of the reference interest rate and the term structure of the interest rate fluctuation rate are used as input variables in the simulation process.
According to the nature of the options contained in the bond, future cash flows in different situations are adjusted and calculated along each possible interest rate change path, and the method is similar to the simulation of American options, and whether the options are executed or not needs to be judged at the moment of each cash flow, so that the cash flow is determined.
OAS is calculated. Mathematically, OAS needs to be obtained by univariate solving the following equation:
where N is the total number of interest paths obtained by the simulation, i is the time step separation point set when the simulation is performed, Then the reference interest rate level in each time step. That is, the OAS is calculated as the possible cash flow/>, for the future time t, in each simulated interest rate path(Note that this is cash flow with expired rights adjusted)) to be added up to obtain a present value, the average value of the present values of all paths is the theoretical value V of the weight-containing bond, and since V is often not equal to the current market price P of the weight-containing bond, the current whole interest rate deadline structure needs to be translated uniformly, and a translation amount enabling V to be equal to P is found through univariate solution, which is OAS.
