Description

Method and device for processing estimated business of professional annuity

Technical Field

The invention belongs to the technical field of blockchains, and particularly relates to a method and a device for processing an estimation service of professional annuity, computer equipment and a computer readable storage medium.

Background

With the advent of the aging of the population in China, the establishment of a perfect pension insurance system has become a concern. Professional annuity is the funds raised by an enterprise annuity plan formulated by law and the enterprise supplementary pension insurance formed by the investment operation income of the enterprise annuity plan.

Currently, the evaluation service of the professional annuity generally comprises a plurality of sub-services, and thus, the evaluation service relates to a main trusted authority and a main trusted authority, a plurality of trusted authorities for managing the sub-services, a plurality of trusted authorities, and a plurality of management authorities such as agents. By taking a plan evaluation example of the professional annuity of a social security (agent), each hosting mechanism on the day of the current pricing date transmits evaluation information corresponding to each participating sub-business to a corresponding trusted mechanism through a data transmission function provided by a deep certificate passing financial data interaction platform, each trusted mechanism receives the evaluation information and transmits the evaluation information to the agent through a socket message interface and a mail after checking, and transmits the evaluation information to a main hosting mechanism, a main trusted mechanism and each hosting mechanism through the deep certificate passing financial data interaction platform and the mail, and the main hosting mechanism and the main trusted mechanism uniformly check the evaluation information corresponding to each sub-business, and then transmit the evaluation information of the evaluation business to the agent through the socket message interface after checking that the evaluation data of the evaluation business is obtained without errors.

However, in the existing scheme, the estimated data is transmitted in a linear mode of two-by-two interaction between different institutions, so that the transmission period of the estimated data between the institutions is prolonged, and the timeliness of the annuity estimated service is reduced. Each institution adopts different equipment and transmission modes to transmit estimated value data, including socket message interfaces, deep certificate passing financial data interaction platforms or offline mails, and the like, and the same data is interacted among a plurality of institutions for multiple times through different transmission modes, so that errors are easy to occur in the data transmission process, and the error is not traced after the problems occur, so that the full-flow supervision of professional annuity estimated value business is very unfavorable.

Detailed Description

Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

In the annuity hosting and investment management model, there are mainly four classes of roles: agent, trusted mechanism, escrow mechanism and throwing pipe mechanism. The agent may be an initiator of the professional annuity plan and is responsible for supervising the implementation and flow of the professional annuity plan. A trusted authority refers to an authority responsible for managing professional annuities by a trusted agent's delegate. The escrow organization refers to a bank or professional organization that receives the entrusted custody of the trusted organization. The pipe throwing mechanism refers to a professional mechanism of entrusted investment management of a receiving mechanism.

For the evaluation service of the professional annuity, a plurality of sub-services can be included, for example, an agent artificially simplifies the operation of the professional annuity, establishes an annuity unified plan (virtual plan) and establishes a main trusted structure, and a main hosting organization carries out the management of the unified plan; further, n real plans can be established under the unified plan: plan a, plan b...plan N. Each plan is operated by a corresponding secondary escrow institution, secondary escrow institution and administration institution. Correspondingly, the auxiliary pipe throwing mechanism corresponding to each plan is responsible for the main pipe throwing mechanism, the main pipe throwing mechanism is responsible for the main managed mechanism, and the main trusted mechanism is responsible for the agent.

Therefore, in the case that the estimated service of the professional annuity is the annuity unified plan, the plurality of sub-services included in the estimated service can be a plurality of real plans under the annuity unified plan, and correspondingly, the plurality of sub-trusted institutions and the plurality of sub-trusted institutions respectively manage the plurality of sub-services, and the main trusted institutions manage the estimated service.

Fig. 1 is a schematic diagram of a processing system for a professional gold estimation service according to an embodiment of the present invention, as shown in fig. 1, a management mechanism involved in the professional gold estimation service may be communicatively connected to a blockchain 10 in the form of nodes, where the nodes may be any type of computing device, such as a server, a user terminal, of a management mechanism, a trusted mechanism, a hosting mechanism, or an agent in an access network. That is, the blockchain 10 is communicatively coupled to a plurality of secondary trusted nodes 20, a plurality of secondary trusted nodes 30, a primary trusted node 40, a primary trusted node 50, and an agent node 60, wherein the plurality of secondary trusted nodes and the plurality of secondary trusted nodes respectively correspond to a plurality of sub-services contained in managing annuity estimation services, and the primary trusted node manage annuity estimation services.

The block chain comprises a series of blocks which are mutually connected according to the generated sequence, each block comprises a hash value of a storage transaction record of the block (the hash value of the block) and a hash value of a previous block, and all the blocks are connected through the hash values to form the block chain. In addition, the block may include information such as a time stamp at the time of block generation. It is essentially a decentralised database, a series of data blocks that are generated by cryptographic means, each of which contains relevant information for verifying the validity of its information (anti-counterfeiting) and generating the next block.

Fig. 2 is a flowchart of a method for processing a professional annuity estimation service according to an embodiment of the present invention, where the method for processing a professional annuity estimation service is applied to a blockchain in a processing system of the professional annuity estimation service, as shown in fig. 2, and the method may include:

In this step, the blockchain may acquire sub-service upper period transaction data of the sub-service managed by the secondary trusted node from the secondary trusted node, and acquire sub-service period estimation data of the sub-service managed by the secondary trusted node from the secondary trusted node, so that sub-service upper period transaction data of each sub-service included in the professional annuity estimation service may be acquired from the plurality of secondary trusted nodes, and sub-service period estimation data of each sub-service included in the professional annuity estimation service may be acquired from the plurality of secondary trusted nodes.

Specifically, the sub-trusted authority corresponding to each sub-service can acquire plan layer transaction data of each plan of the upper pricing day in the respective system, the data is used as sub-service upper transaction data, the sub-service upper transaction data are transmitted to the blockchain through the sub-trusted node, and data uplink is completed, so that the blockchain can acquire sub-service upper transaction data of each sub-service from the sub-trusted authority.

Similarly, the auxiliary supporting mechanism corresponding to each sub-service can acquire planning layer estimated value data of each plan of the pricing day in the corresponding system, the data is used as sub-service current period estimated value data, the sub-service current period estimated value data is transmitted to the blockchain through the auxiliary supporting node, and data uplink is completed, so that the blockchain can acquire the sub-service current period estimated value data of each sub-service from the auxiliary supporting mechanism.

And 102, checking the accuracy of the sub-service period estimated value data according to the sub-service period transaction data to obtain a first checking result of the sub-service.

In this step, the blockchain may verify the accuracy of the sub-service lifetime estimation data obtained from each secondary trusted node based on the sub-service lifetime transaction data obtained from each secondary trusted node.

Specifically, table 1 shows specific contents included in the sub-service upper period transaction data, as can be seen from the data listed in table 1, each sub-service upper period transaction data corresponding to each sub-service includes a plurality of fields, and each field is used for recording a part of contents in the sub-service upper period transaction data, and specifically may include: the annual plan name corresponding to the sub-service (i.e. the name of the sub-service) or the unified plan name belonging to the sub-service (i.e. the name of the estimated service), the annual plan registration number corresponding to the sub-service (i.e. the registration number of the sub-service) or the unified plan name belonging to the sub-service (i.e. the registration number of the estimated service), the pricing day, the unit net value of the upper period of the sub-service, the net value of the pre-transaction asset before the upper period of the sub-service, the net value of the post-transaction asset after the upper period of the sub-service, the initial share of the sub-service before the upper period of the transaction, and the post-transaction share of the sub-service after the upper period of the transaction.

In addition, if the annuity plan (sub-business) further includes a plurality of annuity combinations, that is, the annuity business includes a plurality of sub-businesses, each sub-business may be further divided into a plurality of combinations to perform investment and management, and the sub-business upper-period transaction data corresponding to each sub-business may further include data such as a combination name and a combination code.

TABLE 1

Table 2 shows specific contents contained in the above-mentioned sub-service period estimation data, as can be seen from the data listed in table 2, the sub-service period estimation data corresponding to each sub-service includes a plurality of fields, and each field is used for recording a part of contents in the sub-service period estimation data, and specifically may include: the annual plan name corresponding to the sub-service (i.e. the name of the sub-service) or the unified plan name belonging to the sub-service (i.e. the name of the estimated service), the annual plan registration number corresponding to the sub-service (i.e. the registration number of the sub-service) or the unified plan name belonging to the sub-service (i.e. the registration number of the estimated service), the estimated information level corresponding to the estimated data, the pricing date, the net value of the assets in the sub-service period, the unit net value of the sub-service period, the share of the sub-service period, the profit-loss sign of the sub-service period, the profit-loss net value of the sub-service period and the unit net value increase rate of the sub-service period.

In addition, if the annuity plan (sub-service) further includes a plurality of annuity combinations, that is, the annuity service includes a plurality of sub-services, each sub-service may be further divided into a plurality of combinations to perform investment and management, and the sub-service period estimation data corresponding to each sub-service may further include data such as a combination name and a combination code.

TABLE 2

As can be seen from the data listed in tables 1 and 2, the sub-service upper period achievement data can represent the information of the sub-service achievement recorded by each sub-trusted node at the upper period pricing date, and the sub-service present period estimation data can represent the estimated information of the sub-service estimated by each sub-trusted node at the present period pricing date, so that the accuracy of the sub-service present period estimation data can be checked according to the sub-service upper period achievement data, and the accuracy of the estimated information estimated by each sub-trusted node can be judged, thereby obtaining the first check result of the sub-service.

In the embodiment of the invention, if the accuracy of the sub-service period estimated value data is higher according to the sub-service period transaction data, a first check result passing the check can be generated; if the accuracy of the sub-service period estimated value data is low according to the sub-service period transaction data, a first check result of check failure can be generated.

And step 103, generating a first estimated value report of the sub-service according to the first check result and the sub-service period estimated value data under the condition that the first check result is that the check is passed.

In the step, if the first checking result obtained by the blockchain based on the sub-service prime date estimation data of the sub-service is checked to be passing, the accuracy of the estimated information of the sub-service estimated by each auxiliary hosting node on the prime date pricing day is higher, the sub-service prime date estimation data can be directly used as the final estimated information of the sub-service, and then a first estimated report of the sub-service can be generated according to the first checking result and the sub-service prime date estimation data.

Step 104, the first valuation report is sent to the secondary trusted node and the secondary managed node corresponding to the sub-business, and the primary trusted node, the primary managed node and the agent node.

In this step, after generating the first valuation report of the sub-service, the blockchain may send the first valuation report to the secondary trusted node and the secondary trusted node corresponding to the sub-service, and the primary trusted node, and the agent node, so that each of the management institutions corresponding to the secondary trusted node, the primary trusted node, and the agent node can obtain the valuation information of the sub-service that passes the verification.

It should be noted that, when the blockchain acquires the sub-service current period estimated data of the sub-service from the auxiliary managed node or acquires the sub-service up period transaction data of the sub-service from the auxiliary trusted node, the receiving node identifier for receiving the first estimated report may also be acquired from the auxiliary managed node or the auxiliary trusted node, so that after the first estimated report is generated, according to the receiving node identifier, the receiving node capable of receiving the first estimated report may be determined from each node in communication connection with the blockchain, instead of transmitting the first estimated report to all nodes in communication connection with the blockchain, thereby realizing directional transmission of data and ensuring the security of the data.

In addition, the blockchain can acquire the sub-service period estimated data of the sub-service from the auxiliary trusteeship node, and can acquire a transmitting node identifier (namely the identifier of the auxiliary trusteeship node) or acquire the sub-service up-period traffic data of the sub-service from the auxiliary trusteeship node, and can acquire a transmitting node identifier (namely the identifier of the auxiliary trusteeship node), so that after the sub-service period estimated data or the sub-service up-period traffic data are received, whether a data source accords with a preset rule can be checked, if the data source does not accord with the preset rule, a subsequent step is not executed, and information of a data uplink error is fed back to the data transmitting node, so that the data uplink process is prevented from being wrong; meanwhile, if the first check result is the check failure, the first check result of the check failure can be fed back to the data sending node so as to remind the data sending node of the check failure.

In summary, the method for processing the estimated service of the professional annuity provided by the embodiment of the invention includes: sub-service up-period transaction data of the sub-service are obtained from the auxiliary trusted node, and sub-service period estimated value data of the sub-service are obtained from the auxiliary trusted node; checking the accuracy of the sub-service period estimated value data according to the sub-service period transaction data to obtain a first checking result of the sub-service; under the condition that the first check result is that the check is passed, generating a first estimated value report of the sub-service according to the first check result and the sub-service period estimated value data; and sending the first valuation report to the secondary trusted node and the secondary trusted node corresponding to the sub-business, and the primary trusted node, the primary trusted node and the agent node. In the invention, each management mechanism related to the estimated service of the professional annuity is in communication connection with the blockchain in the form of nodes, each node only needs to transmit sub-service upper-period transaction data or sub-service period estimated data required by the estimated service to the blockchain, the blockchain is used for checking the accuracy of the sub-service period estimated data according to the sub-service upper-period transaction data, and the checking result and the generated estimated report are directionally transmitted to each node, so that the linear data transmission process of pairwise interaction of data between the nodes corresponding to each mechanism is avoided, the transmission period of the data between the mechanisms is shortened, and the efficiency and timeliness of the estimated service are improved; meanwhile, each management organization only needs to transmit the sub-service up-period transaction data or sub-service current period estimated value data to the blockchain once through the corresponding nodes, and the corresponding nodes of each management organization do not generate data mutually, so that errors in the data transmission process can be reduced, and the data can be traced conveniently after problems occur, thereby being beneficial to realizing supervision and management of each item of data in the annual gold estimated value service.

Fig. 3 is a flowchart of steps of another method for processing an estimation service of professional annuity according to an embodiment of the present invention, where, as shown in fig. 3, the method may include:

step 201, the sub-service up-period transaction data is obtained from the sub-trusted node and decrypted.

In this step, the blockchain may obtain sub-service upper-period transaction data of sub-services managed by the sub-trusted node from the sub-trusted node.

Specifically, since the sub-service upper period transaction data may be encrypted data encrypted according to the advanced encryption standard algorithm and the RSA encryption algorithm, the sub-service upper period transaction data needs to be further decrypted, so as to obtain specific content contained in the sub-service upper period transaction data.

In the embodiment of the present invention, before the sub-trusted node links up sub-service data, the sub-service data may be encrypted according to an advanced encryption standard algorithm (Advanced Encryption Standard, AES) and an RSA encryption algorithm, and a specific encryption process may include:

(1) The blockchain creates an RSA secret key pair (an RSA public key and an RSA private key), sends the RSA public key to each auxiliary trusted node, and reserves the RSA private key;

(2) Each secondary trusted node creates an AES key, encrypts the sub-service up-date transaction data to be uplinked, and then encrypts the AES key with the RSA public key.

Correspondingly, after the blockchain receives the encrypted ciphertext from each sub-trusted node, the ciphertext can be decrypted by utilizing an RSA private key to obtain an AES key, and then the decrypted AES key is used for decrypting the data ciphertext to obtain sub-service upper-period transaction data of the uplink of each sub-trusted node.

Step 202, acquiring the sub-business period estimation data from the auxiliary hosting node and decrypting the sub-business period estimation data.

In this step, the blockchain may obtain, from the secondary hosting node, sub-business lifetime estimate data for the sub-business managed by the secondary hosting node.

Specifically, since the sub-service lifetime estimation data may be an encrypted ciphertext encrypted according to an advanced encryption standard algorithm and an RSA encryption algorithm, it is necessary to further decrypt the sub-service lifetime estimation data to obtain specific contents contained in the sub-service lifetime estimation data.

In the embodiment of the present invention, before the auxiliary hosting node links the sub-service lifetime estimation data, the sub-service lifetime estimation data may be encrypted according to AES and RSA encryption algorithms, and a specific encryption process may include:

(1) The blockchain creates an RSA secret key pair (an RSA public key and an RSA private key), sends the RSA public key to each auxiliary trust node, and reserves the RSA private key;

(2) Each secondary escrow node creates an AES key, encrypts sub-service lifetime estimation data to be uplinked, and then encrypts the AES key with the RSA public key.

Correspondingly, after the blockchain receives the encrypted ciphertext from each auxiliary hosting node, the ciphertext can be decrypted by utilizing an RSA private key to obtain an AES key, and then the decrypted AES key is used for decrypting the data ciphertext to obtain the sub-service lifetime estimated data of the uplink of each auxiliary hosting node.

And 203, checking the accuracy of the sub-service period estimated value data according to the sub-service period transaction data to obtain a first checking result of the sub-service.

This step may be referred to specifically as step 102 above.

Optionally, step 203 may specifically include:

substep 2031, determining a difference between the net value of the last-period-unit-of-transaction and the net value of the current-period-unit, a difference between the last-period-post-transaction share and the current-period-share estimate, and a difference between the last-period-post-transaction net value of the asset and the current-period-asset net value estimate.

In this step, the sub-service upper-period transaction data of the sub-service may include: the upper-period post-commit unit net worth, the upper-period post-commit share, and the upper-period post-commit asset net worth may be the unit net worth listed in the table, the upper-period post-commit share may be the post-commit share listed in the table, and the upper-period post-commit asset net worth may be the post-commit asset net worth listed in the table, referring to table 1.

The sub-service lifetime estimation data of the sub-service may include: the current unit net worth, the current share estimate, and the current asset net worth may be units net worth listed in a table, the current share estimate may be a share listed in a table, and the current asset net worth may be an asset net worth listed in a table, referring to table 2.

Specifically, in order to verify the accuracy of the sub-business period estimated value data according to the sub-business upper period bargain data, whether the upper period bargain unit net value in the sub-business upper period bargain data is equal to the current period unit net value estimated value in the sub-business period estimated value data or not can be directly compared, whether the upper period bargain share in the sub-business upper period bargain data is equal to the current period share estimated value in the sub-business current period estimated value data or not is judged, whether the upper period bargain in the sub-business upper period bargain data is equal to the current period asset net value estimated value in the sub-business current period estimated value data or not is judged, if so, the accuracy of the sub-business current period estimated value data is higher, and a first verification result passing verification is generated; if the sub-service period estimated data are not equal, the accuracy of the sub-service period estimated data is lower, and a first check result of check failure can be generated.

In addition, the estimated value data of the sub-service period can not be kept in absolute agreement with the data of the sub-service upper period, and the accuracy of the estimated value data of the sub-service period can be judged to be higher under the condition that the estimated value data of the sub-service period is positioned in a certain range of the data of the sub-service upper period.

Therefore, the difference value between the net value of the upper-period unit in the upper-period transaction data of the sub-service and the net value of the current-period unit in the estimation data of the sub-service, the difference value between the share of the upper-period transaction in the upper-period transaction data of the sub-service and the estimation value of the current-period share in the estimation data of the sub-service and the difference value between the net value of the upper-period transaction asset in the upper-period transaction data of the sub-service and the net value of the current-period asset in the estimation data of the sub-service can be calculated first.

A substep 2032, determining that the first verification result of the sub-service is verification passing when the difference between the net value of the last-period-unit and the net value of the current-period-unit, the difference between the share of the last-period-unit and the net value of the current-period-unit, and the difference between the net value of the last-period-unit and the net value of the current-period-unit are within the range of a first preset difference.

In this step, it may be further determined whether the difference between the net value of the last-period unit and the net value of the current-period unit, the difference between the share of the last-period unit and the net value of the current-period share, and the difference between the net value of the last-period unit and the net value of the current-period asset are all within a range of a first preset difference. If yes, the accuracy of the sub-service current estimated value data is higher, and a first check result passing the check is generated; if not, the accuracy of the sub-service period estimated value data is lower, and a first check result of check failure can be generated.

In an embodiment of the present invention, the first preset difference may be a preset fixed value or percentage, for example, the first preset difference may be 10% of the net value of the last unit of commit/the share after last commit/the net value of the last asset.

In addition, the verification process for the sub-service upper period transaction data and the sub-service period estimated value data may further include internal verification, that is, verification of accuracy between specific data in the sub-service upper period transaction data included in table 1 and verification of accuracy between specific data in the sub-service period estimated value data included in table 2.

For example, it may be checked whether the before-transaction equity is equal to the product of the unit equity and the early-period share, whether the after-transaction equity is equal to the product of the unit equity and the after-transaction share in table 1, and, if the annuity plan includes a plurality of combinations, it is necessary to check whether the sum of equities of all the combinations is equal to the equity of the annuity plan. It may be checked whether the sum of the equities of all combinations in table 2 is equal to the equities of the annuity plan and whether the unit equities are equal to the equity to share ratio.

Further, the sub-service period estimation data may further include a unit net value increase rate estimation, so that the accuracy of the unit net value increase rate estimation in the sub-service period estimation data may be further determined, specifically, firstly, a difference value between the unit net value in table 2 and the unit net value in table 1 is calculated, then, a ratio of the difference value to the unit net value in table 1 is used as the unit net value increase rate estimation, and whether the unit net value increase rate estimation is equal to the unit net value increase rate in table 2 or is within a preset range of the unit net value increase rate in table 2 is determined, if yes, the accuracy of the unit net value increase rate estimation is higher, and if not, the accuracy of the unit net value increase rate estimation is lower.

And 204, generating a first estimated value report of the sub-service according to the first check result and the sub-service period estimated value data under the condition that the first check result is that the check is passed.

This step may refer to step 103, and will not be described herein.

Step 205, the first valuation report is sent to a secondary trusted node and a secondary managed node corresponding to the sub-service, and the primary trusted node, the primary managed node and the agent node.

This step may refer to step 104, and will not be described herein.

And 206, acquiring first estimated service upper-period transaction data of the estimated service from the master trusted node.

After step 202, i.e. after obtaining sub-service up-period transaction data from the secondary trusted node and decrypting, and sub-service home period estimate data from the secondary trusted node and decrypting, step 206 may be performed.

In this step, the blockchain may obtain first estimated service upper-phase commit data for the estimated service from the master trusted node.

The first estimated value service upper period transaction data can also be an encrypted ciphertext encrypted according to an advanced encryption standard algorithm and an RSA encryption algorithm, so that the first estimated value service upper period transaction data needs to be further decrypted, and the specific content contained in the first estimated value service upper period transaction data is obtained.

Specifically, the main trusted authority corresponding to the estimated service of the professional annuity can acquire unified plan layer transaction data of the upper pricing day in the system of the main trusted authority, the data is used as first estimated service upper transaction data of the estimated service, the first estimated service upper transaction data is transmitted to the blockchain through the main trusted node, and the data uplink is completed, so that the blockchain can acquire the first estimated service upper transaction data of the estimated service from the main trusted authority.

And step 207, checking the accuracy of the sub-service period estimated value data according to the first estimated service period up-date transaction data to obtain a second checking result of the estimated service.

In this step, the blockchain may verify the accuracy of the sub-service lifetime estimation data obtained from each secondary escrow node based on the first estimation service lifetime achievement data of the estimation service obtained from the primary escrow node.

Optionally, step 207 may specifically include:

sub-step 2071, determining a sum of the net value estimates of the current period units, a sum of the net value estimates of the current period shares, and a sum of the net value estimates of the current period assets corresponding to the plurality of sub-services.

In this step, the sub-service period valuation data of the sub-service may include a period unit net valuation, a period share valuation, and a period asset net valuation, and the first valuation service upper period diagonalization data of the valuation service may include: the net value of the estimated service upper period transaction unit, the estimated service upper period post-transaction share and the estimated service upper period post-transaction asset net value.

Specifically, to verify the accuracy of the sub-service period estimation data according to the first estimation service upper period transaction data of the estimation service, the sum of the current period unit net value estimation, the sum of the current period share estimation and the sum of the current period asset net value estimation corresponding to the plurality of sub-services can be calculated first.

Sub-step 2072, determining that the second check result of the estimated service is verification passing when the difference between the sum of the net value estimates of the current period units and the net value of the estimated service upper period unit, the difference between the sum of the estimated value of the current period share and the share of the estimated service upper period unit and the difference between the sum of the net value estimates of the current period asset and the net value of the asset after the estimated service upper period unit and the difference of the net value of the estimated service upper period unit are all within the range of the second preset difference.

In this step, it may be further determined whether the difference between the sum of the net value estimates of the current period units and the net value of the estimated service upper period unit, the difference between the sum of the estimated value of the current period share and the estimated service upper period post-commit share, and the difference between the sum of the net value estimates of the current period asset and the net value of the estimated service upper period post-commit asset are all within a second preset difference range. If yes, the accuracy of the sub-service current estimated value data is higher, and a second check result passing the check is generated; if not, the accuracy of the sub-service period estimated value data is lower, and a second check result of check failure can be generated.

In an embodiment of the present invention, the second preset difference may be a preset fixed value or percentage, for example, the first preset difference may be 10% of the net value of the last unit of commit/the last share of commit/the net value of the last asset.

And step 208, generating a second estimated value report of the estimated service according to the second checking result and a plurality of sub-service period estimated value data when the second checking result is that the checking is passed.

In the step, if the second checking result obtained by checking the sub-service period estimation data based on the first estimation service upper period transaction data of the estimation service is that the checking is passed, the accuracy of the estimated information of the sub-service estimated by each auxiliary hosting node on the current period pricing day is higher, the sub-service period estimation data can be directly used as the final estimation information of the sub-service, and then a second estimation report of the sub-service can be generated according to the second checking result and the sub-service period estimation data.

In addition, the second estimation report may further include first estimation service period estimation data of the estimation service calculated according to the first estimation service upper period transaction data of the estimation service and sub-service period estimation data of each sub-service.

In the embodiment of the present invention, the first estimated service lifetime estimated data of the estimated service may include: the method comprises the steps of estimating the net value of the asset in the service period, estimating the net value of the unit in the service period, estimating the loss and benefit net value of the service period, estimating the loss and benefit sign of the service period and estimating the net value increase rate of the unit in the service period.

Correspondingly, each item of data in the first estimated service period estimated data of the estimated service can be obtained through the following process:

(1) Valuation business home period asset equity = sum of home period asset equity valuations in sub-business home period valuation data of each sub-business;

(2) Estimated service period unit net value estimation = sum of the net value estimates of the current period assets in the sub-service period estimation data of each sub-service/estimated service period post-commit share in the first estimated service period commit data of the estimated service;

or, the net value of the estimated service period unit estimated value=the net value of the estimated service after the estimated service is submitted to the upper period in the first estimated service upper period submitted data of the estimated service/the estimated service after the estimated service is submitted to the upper period in the first estimated service upper period submitted data of the estimated service;

(3) Estimated service period loss and gain net estimation = sum of loss and gain net in sub-service period estimation data of each sub-service;

(4) The estimated service period loss and benefit sign estimated value is determined according to the positive and negative of the estimated service period loss and benefit net estimated value, if the estimated service period loss and benefit net estimated value is positive, the estimated service period loss and benefit sign estimated value is the benefit; if the estimated service period loss and benefit net estimated value is negative, estimating a service period loss and benefit mark estimated value as loss;

(5) Estimated service period unit net value increase rate estimation= (estimated service period unit net value estimation-estimated service upper period unit net value in estimated service upper period transaction data of estimated service)/estimated service upper period transaction unit net value in first estimated service upper period transaction data of estimated service.

Step 209, sending the second valuation report to the master trusted node, master managed node, and agent node.

In this step, after generating the second valuation report of the valuation service, the blockchain may send the second valuation report to the master trusted node, and the agent node, so that each of the authorities corresponding to the master trusted node, and the agent node can obtain the valuation information of the valuation service that passes the verification.

It should be noted that, when the blockchain acquires the sub-service current period estimated data of the sub-service from the auxiliary managed node, or acquires the sub-service upper period bargain data of the sub-service from the auxiliary trusted node, or acquires the first estimated service upper period bargain data of the estimated service from the main trusted node, the receiving node identifier for receiving the second estimated report may also be acquired from the auxiliary managed node, the auxiliary trusted node or the main trusted node, so that after the second estimated report is generated, according to the receiving node identifier, the receiving node capable of receiving the second estimated report may be determined from each node in communication connection with the blockchain, instead of transmitting the second estimated report to all nodes in communication connection with the blockchain, thereby realizing directional transmission of data and ensuring the security of the data.

In addition, the blockchain can acquire sub-business prime estimation data of sub-business from the auxiliary trusteeship node, can acquire a sending node identifier (namely the identifier of the auxiliary trusteeship node), can acquire sub-business upper-period transaction data of the sub-business from the auxiliary trusteeship node, can acquire a sending node identifier (namely the identifier of the auxiliary trusteeship node), or can acquire a sending node identifier (namely the identifier of the main trusteeship node) when acquiring first estimation business upper-period transaction data of estimation business from the main trusteeship node, so that after receiving the sub-business prime estimation data, the sub-business upper-period transaction data and the first estimation business upper-period transaction data, whether a data source accords with a preset rule or not can be checked, if not accords with the preset rule, the subsequent step is not executed, and data uplink error information is fed back to the data sending node, thereby avoiding the data uplink process error; meanwhile, if the second check result is the check failure, the second check result of the check failure can be fed back to the data sending node so as to remind the data sending node of the check failure.

Step 210, obtaining second estimated service upper period transaction data of the estimated service from the main hosting node.

After step 202, i.e., after sub-service up-period transaction data is obtained from the secondary trusted node and decrypted, and sub-service home period estimate data is obtained from the secondary trusted node and decrypted, step 210 may be performed.

In this step, the blockchain may obtain second valuation business upper-period commit data for the valuation business from the master hosting node.

The second estimated value service upper period transaction data can also be an encrypted ciphertext encrypted according to an advanced encryption standard algorithm and an RSA encryption algorithm, so that the second estimated value service upper period transaction data needs to be further decrypted, and the specific content contained in the second estimated value service upper period transaction data is obtained.

Specifically, the main hosting mechanism corresponding to the estimated service of the professional annuity can acquire unified plan layer transaction data of the upper period pricing day in the system of the main hosting mechanism, the data is used as second estimated service upper period transaction data of the estimated service, the second estimated service upper period transaction data is transmitted to the blockchain through the main hosting node, and the data uplink is completed, so that the blockchain can acquire the second estimated service upper period transaction data of the estimated service from the main hosting mechanism.

Step 211, checking the accuracy of the sub-service period estimated value data according to the second estimated service period up-date transaction data, and obtaining a third checking result of the estimated service.

In this step, the blockchain may verify the accuracy of the sub-service lifetime estimation data obtained from each secondary hosting node based on the second estimation service lifetime achievement data of the estimation service obtained from the primary hosting node.

The specific implementation of this step is similar to step 207 and will not be described in detail here.

And 212, generating a third estimated value report of the estimated service according to the third check result and the plurality of sub-service period estimated data when the third check result is that the check is passed.

In the step, if the third checking result obtained by checking the sub-service period estimation data based on the second estimation service upper period transaction data of the estimation service is that the checking is passed, it is indicated that the accuracy of the estimated information of the sub-service estimated by each auxiliary hosting node on the current period pricing day is higher, the sub-service period estimation data can be directly used as the final estimation information of the sub-service, and then the third estimation report of the sub-service can be generated according to the third checking result and the sub-service period estimation data.

In addition, the third estimation report may further include second estimation service period estimation data of the estimated service calculated according to the second estimation service upper period transaction data of the estimated service and sub-service period estimation data of each sub-service.

Specifically, the process of calculating each item of data in the second estimated service lifetime estimated data of the estimated service is similar to the process of calculating each item of data in the first estimated service lifetime estimated data of the estimated service in step 208, and will not be described herein.

Step 213, sending the third valuation report to the master trusted node, master managed node, and agent node.

In this step, after generating the third valuation report of the valuation service, the blockchain may send the third valuation report to the master trusted node, and the agent node, so that each of the authorities corresponding to the master trusted node, and the agent node can obtain the valuation information of the valuation service that passes the verification.

And step 214, checking the consistency of the second estimation report and the third estimation report to obtain a fourth checking result of the estimation service.

After the second estimate report is obtained via step 208 and the third estimate report is obtained via step 212, step 214 may be performed.

In this step, the consistency of the second and third valuation reports may be verified, resulting in a fourth verification result of the valuation service.

In an embodiment of the present invention, the second estimation report may include: the sub-service period estimation data and the first estimated service period estimation data of the estimated service may include: sub-service lifetime estimation data and second estimated service lifetime estimation data of an estimated service.

Specifically, whether the sub-service period estimated data in the second estimated report and the sub-service period estimated data in the third estimated report are equal or whether the difference value is within a preset range can be compared, if yes, the sub-service period estimated data in the second estimated report and the sub-service period estimated data in the third estimated report are consistent, if not, the sub-service period estimated data in the second estimated report and the sub-service period estimated data in the third estimated report are inconsistent, namely errors are generated in the data collection or calculation process, and therefore the fourth verification result can be determined to be verification failure; meanwhile, whether the first estimated service period estimated data in the second estimated report and the second estimated service period estimated data in the third estimated report are equal or not or whether the difference value is in a preset range or not can be compared, if yes, the first estimated service period estimated data and the second estimated service period estimated data are consistent, if not, the first estimated service period estimated data and the second estimated service period estimated data are inconsistent, namely errors are generated in the data collecting or calculating process, and therefore the fourth checking result can be determined to be failed in checking. If the two judging results are yes, determining that the fourth checking result is the passing checking result.

And step 215, generating a fourth estimated value report of the estimated service according to the fourth checking result, the second estimated value report and the third estimated value report when the fourth checking result is checked to be passed.

In this step, if the fourth check result obtained by the blockchain based on the second estimation report and the third estimation report is that the check is passed, it is indicated that the accuracy of the estimation information of the sub-service estimated by each auxiliary managed node on the current pricing day is higher, then the sub-service current estimation data can be directly used as the final estimation information of the sub-service, and the first estimation service current estimation data obtained by calculating the first estimation service last-stage transaction data and the sub-service current estimation data obtained by the main trusted node is consistent with the second estimation service current estimation data obtained by calculating the second estimation service last-stage transaction data and the sub-service current estimation data obtained by the main managed node, then the accuracy of the estimation information of the estimation service on the current pricing day is higher, and then the first estimation service current estimation data or the second estimation service current estimation data can be directly used as the final estimation information of the estimation service, and further the fourth estimation report of the estimation service can be generated according to the fourth check result and the second estimation report and the third estimation report, so that the final estimation report of the sub-service and the final estimation service information are included in the fourth estimation report.

Step 216, sending the fourth valuation report to the master trusted node, master managed node, and agent node.

In this step, after generating the fourth valuation report of the valuation service, the blockchain may send the fourth valuation report to the master trusted node, and the agent node, so that each of the authorities corresponding to the master trusted node, and the agent node can obtain valuation information of the sub-service and the valuation service that pass the verification.

In addition, if the processing system of the estimated service of the occupational annuity further comprises a pipe throwing node corresponding to the pipe throwing mechanism, the generated related estimated report can also be sent to the pipe throwing node, so that the pipe throwing mechanism corresponding to the pipe throwing node can acquire the estimated information of the sub-service and the estimated service which pass the verification.

In addition, the auxiliary trusted node can also correspondingly acquire upper-period combined data corresponding to each combined layer and uplink the upper-period combined data, so that the blockchain can utilize the upper-period combined data and the present-period combined estimated value data to carry out verification after acquiring the upper-period combined data and the present-period combined estimated value data corresponding to each combined layer to obtain a verification result aiming at the combination, and obtain the present-period combined estimated value data.
