It should be understood that the specific embodiments described herein are merely illustrative of and not restrictive on the broad application.

Referring to fig. 1, an embodiment of the present application provides a method for auditing a resource expected result based on a block chain, which is applied to a designated terminal, and includes the following steps:

s1, extracting first data from a preset first block chain network, wherein the specified terminal is a block chain node of the first block chain network which is constructed in advance and a block chain node of a second block chain network which is constructed in advance, the first block chain network at least comprises block chain link points which provide expected calculation and use data of resources, and the second block chain network at least comprises expected result audit block chain nodes of the resources;

s2, acquiring second data of the resources acquired in real time, and according to a formula:

h (t) = min (G (t), m), wherein

the differential function of the difference function to the time is adopted, min refers to a minimum function, t refers to the time, and m refers to a preset error parameter value larger than 0; acquiring a first time length of the function H (t) on a time axis when the time length is not equal to m and a second time length when the time length is equal to m, and according to a formula: normal time ratio = the first length of time/(the second length of time)/A time length + the second time length), calculating the normal time ratio, and judging whether the normal time ratio is greater than a preset ratio threshold; if the normal time ratio is larger than a preset ratio threshold, generating a resource expectation result by utilizing a preset resource expectation algorithm according to the first data;

s3, sending the resource expected result to a plurality of resource expected result auditing block chain nodes in the second block chain network, and requiring a plurality of resource expected result auditing block chain nodes to audit the resource expected result;

s4, return information of the plurality of resource expected result auditing block link points for auditing the resource expected results is received, wherein the return information comprises that the auditing is passed or the auditing is not passed;

s5, judging whether the return information meets a preset block chain recording condition or not;

and S6, if the return information meets the preset block chain recording condition, recording the expected resource result into the second block chain network.

According to the method, the designated terminal is simultaneously set as the block chain link points of the first block chain network and the second block chain network by adopting the design of the block chain, so that the first data for generating the resource expected result can be extracted from the public account book of the first block chain network, the reliability of the first data is ensured (by utilizing the characteristic that the data of the block chain is not easy to be distorted), the resource expected result is audited and recorded by utilizing the second block chain network, the auditing process is transparent, the efficiency is improved, the design of the block chain is further adopted, the provided resource expected calculation use data and the audited resource expected result are divided, and the hierarchical management and possible error tracing are facilitated. And the second data is processed to judge whether the resource has the possibility of abnormity or counterfeit data, so that the reliability of the expected result is improved.

As described in the step S1, the first data is extracted from a preset first blockchain network, where the designated terminal is a blockchain node of a first blockchain network that is pre-constructed and a blockchain node of a second blockchain network that is pre-constructed, the first blockchain network includes at least a blockchain node that provides the resource-expected calculation-use data, and the second blockchain network includes at least a resource-expected result audit blockchain node. Such as financial, and expected budget. Wherein the first blockchain network and the second blockchain network may be public chains, alliance chains, or private chains. The public ledger of the first blockchain network is used to maintain data that provides an anticipated calculated usage of the resource, such as a division expense plan made by the division, and the like. And the public ledger of the second block chain network is used for storing the expected result of the approved resource. The designated terminal is simultaneously located in the first block chain network and the second block chain network, so that a public account book of the first block chain network and a public account book of the second block chain network are simultaneously provided, data sources of the whole process of checking the first data, the generated resource expected result and the resource expected result are real and credible, and information safety is improved. Wherein the block link points of the first block chain network may record data used to generate the resource expectation result into a public ledger of the first block chain network. Therefore, in the method for auditing the expected result of the resource based on the blockchain, the first data is derived from the public ledger of the first blockchain network and is difficult to be tampered, so that the problem of questioning the reliability of the data in the traditional technology is solved; and the auditing of the expected result of the resource is realized in the second block chain network and recorded in the second block chain network, so that the technical effects of credibility of the expected result of the resource, hierarchical management and possible error tracing are realized.

As stated in step S2 above, the second data of the resource collected in real time is obtained, and according to the formula:

h (t) = min (G (t), m), wherein

E (t) = F (t) -F (t), obtaining a function H (t), wherein F (t) is a function of the second data of the resource changing along with time, F (t) is a preset standard second data changing function, and E (t) isA difference function of said function F (t) and said standard second data variation function F (t),

the differential function of the difference function to the time is adopted, min refers to a minimum function, t refers to the time, and m refers to a preset error parameter value larger than 0; acquiring a first time length of the function H (t) on a time axis when the function H (t) is not equal to m and a second time length when the function H (t) is equal to m, and according to a formula: the normal time ratio = the first time length/(the first time length + the second time length), the normal time ratio is calculated, and whether the normal time ratio is greater than a preset ratio threshold is judged; and if the normal time ratio is greater than a preset ratio threshold, generating a resource expectation result by using a preset resource expectation algorithm according to the first data. The function H (t) is used for representing the condition of the second data, and when the value of the function H (t) is m, the function H (t) indicates that the value of the second data is overlarge and is in an abnormal state; when the value of the function H (t) is not m, the numerical value of the second data is normal and is in a normal state, the normal time ratio is calculated according to the numerical value, and whether the normal time ratio is larger than a preset threshold value or not is judged; and if the normal time ratio is greater than a preset ratio threshold, generating a resource expectation result by using a preset resource expectation algorithm according to the first data. Wherein the first data is used to generate the resource expectation result, and thus the resource expectation result can be generated. According to the first data, a preset resource expectation algorithm is used to generate a resource expectation result, which may be any manner, for example: dividing income data and expenditure data from the first data; judging whether the income data and the expenditure data are credible or not; if the income data and the expenditure data are credible, respectively recording as credible income and credible expenditure; counting the credible income and credible expense so as to obtain credible total income and credible total expense; generating a resource expectation result comprising the trusted total revenue and the trusted total expenditure.

Further, the first data and the second data may or may not be related to each other. The second data is used for laterally judging whether the data of the resource has the possibility of abnormity or forgery. The second data may be determined in any manner, for example, by retrieving the second data from a preset data table, wherein the data table is recorded with a plurality of data categories. The manner of acquiring the second data is, for example, random extraction or the like.

As described in step S3 above, the resource expected result is sent to a plurality of resource expected result auditing block chain nodes in the second block chain network, and a plurality of resource expected result auditing block chain nodes are required to audit the resource expected result. The resource expected result auditing blockchain node may be all blockchain nodes in the second blockchain network or a part of blockchain nodes. Sending the resource expected result to a plurality of resource expected result auditing block chain nodes in the second block chain network, and requiring the plurality of resource expected result auditing block chain nodes to audit the resource expected result, for example, the process includes: acquiring a plurality of resource expected result audit block chain nodes selected according to a preset share authorization certification mechanism in the second block chain network; sending an audit request to all the chain nodes of the resource expected result audit block, and requiring the chain nodes of the resource expected result audit block to send reply information; receiving reply information sent by the link node of the resource expected result audit block, and recording link points of the resource expected result audit block, which are willing to be audited, of the reply information as final link nodes of the resource expected result audit block; and sending the resource expected result to a plurality of final resource expected result auditing block chain nodes, and requiring the plurality of final resource expected result auditing block chain nodes to audit the resource expected result.

As stated in step S4, return information of auditing the resource expected results by multiple resource expected result auditing block nodes is received, where the return information includes that the auditing is passed or the auditing is not passed. The link points of the audit block of different resource expected results are not necessarily identical in audit mode, so the audit results may be different, and are respectively audit passed or audit not passed. In order to avoid misjudgment, return information of the resource expected result by the link points of the plurality of resource expected result auditing blocks is received and comprehensively considered to determine whether the resource expected result is recorded into a public account book of the second block chain network.

As described in step S5, it is determined whether the returned information satisfies a preset blockchain recording condition. The mode of judging whether the returned information meets the preset block chain recording condition or not can be any mode, for example, when the number of the returned information which passes the examination reaches the condition of a preset threshold value, the preset block chain recording condition is judged to be met; or when the ratio of the number of the returned information which passes the audit to the number of all the returned information is larger than the preset ratio threshold, judging that the preset block chain recording condition is met.

As described in step S6, if the return information satisfies the preset blockchain recording condition, the expected resource result is recorded into the second blockchain network. If the returned information meets the preset block chain recording condition, most of the audit block chain nodes in the second block chain network accept the expected resource result, and therefore the expected resource result is recorded into the second block chain network. So that a blockchain node in a second blockchain network can learn the expected result of the resource from the second blockchain network.

In one embodiment, the resource is a resource of a designated object, the first data includes predicted resource increase amounts and predicted resource consumption amounts of a plurality of sub-objects of the designated object, and the step S2 of generating a resource expectation result by using a preset resource expectation algorithm according to the first data includes:

s201, counting the estimated resource increment and the estimated resource loss of a plurality of sub-objects, thereby obtaining the estimated resource increment A from the first sub-object to the nth sub-object ₁ 、A ₂ …、A _n And predicted resource consumption amounts B of the first sub-object through the nth sub-object ₁ 、B ₂ …、B _n And obtaining the first object from the pre-stored relationship table of the importance degree of the sub-objectImportance degree parameter p of sub-object to nth sub-object ₁ 、p ₂ …、p _n ；

S202, according to a formula:

calculating a sensitive factor M;

s203, judging whether the sensitivity factor M is larger than a preset sensitivity threshold value;

and S204, if the sensitivity factor M is not larger than a preset sensitivity threshold, generating a resource expected result, wherein the resource expected result at least comprises an expected resource increment and an expected resource loss of a plurality of sub-objects.

As described above, generating the resource expectation result is achieved. The first data of the present application includes, for example, a department expected income and a department expected expenditure of a plurality of departments, and the resource expected result can be generated based on the department expected income and the department expected expenditure. Wherein due to the different importance of different departments, the corresponding department budget is also affected accordingly. Accordingly, the present application employs an importance level parameter p ₁ 、p ₂ …、p _n To represent the degree of importance of the department, and according to the formula:

calculating a sensitivity factor M, and if the sensitivity factor M is not greater than a preset sensitivity threshold, generating a resource expected result, wherein the resource expected result at least comprises expected income of departments and expected expenses of the departments of the multiple departments. Wherein the expected revenue of the first department to the nth department is A ₁ 、A ₂ …、A _n The estimated expenditure of the first department to the nth department is B ₁ 、B ₂ …、B _n . Thereby making the resource expectation more targeted so as to ensure the resource expectation of important departments.

In one embodiment, the step S3 of sending the resource expected result to a plurality of resource expected result auditing block chain nodes in the second block chain network and requiring the plurality of resource expected result auditing block chain nodes to audit the resource expected result includes:

s301, acquiring a plurality of resource expected result audit block chain nodes selected according to a preset consensus mechanism in the second block chain network;

s302, sending an audit request to all the chain nodes of the resource expected result audit block, and requiring the chain nodes of the resource expected result audit block to send reply information;

s303, receiving reply information sent by the resource expected result audit block chain node, and recording the link point of the resource expected result audit block which is in favor of audit as a final resource expected result audit block chain node;

s304, sending the resource expected result to a plurality of final resource expected result auditing block chain nodes, and requiring the plurality of final resource expected result auditing block chain nodes to audit the resource expected result.

As described above, sending to multiple audit block chain nodes is achieved. The embodiment preferably adopts a share authorization certification mechanism as a consensus mechanism of the blockchain network. The certification mechanism of the share authorization refers to that all the block chain nodes select a plurality of consignment block chain nodes, so that the consignment block chain nodes represent all the block chain link point pairs to judge whether data (such as transactions) are recorded into a public ledger, and the defect that the block chain runs slowly when the number of the block chain link points is too large is avoided. Therefore, the block chain nodes are examined according to a plurality of resource expected results thrown by the share authorization certification mechanism to determine whether to add the resource expected results into the block chain network. In addition, in order to prevent the inaccurate final decision caused by the fact that part of the link points of the audit block of the expected result of the resource cannot participate in the audit (for example, the link nodes of the audit block of the expected result of the part of the resource are not started, or the communication fails, etc.), the embodiment also adopts a mode of sending the audit request in advance to determine the link nodes of the audit block willing to be audited, and to mark the link nodes as the link nodes of the audit block of the expected result of the final resource, and sends the preset specified transfer route to a plurality of the link nodes of the final audit block, thereby reducing unnecessary network overhead (the overhead of sending the audit request is far less than that of sending the expected result of the resource), and ensuring the accuracy of subsequent judgment (excluding the nodes which cannot participate in the audit).

In one embodiment, the step S5 of determining whether the returned information satisfies a preset blockchain recording condition includes:

s501, counting the return information to obtain the total number of the received return information and the number of the returned information which passes the auditing;

s502, calculating a quotient value of dividing the number of the returned information which passes the examination by the total number of the returned information;

s503, judging whether the quotient value is larger than a preset block chain recording parameter threshold value or not;

and S504, if the quotient value is greater than a preset block chain recording parameter threshold value, judging that the return information meets a preset block chain recording condition.

As described above, it is achieved that whether the return information satisfies a preset block chain recording condition is judged. The method and the device adopt the quotient of the number of the returned information which passes the examination and the total number of the returned information to be used as the basis for judging whether the returned information meets the preset block chain recording condition. If the quotient value is larger than a preset block chain recording parameter threshold value, the occupation ratio of the resource expected result audit block chain nodes which approve the resource expected result in all the resource expected result audit block chain nodes is large enough, and accordingly the returned information is judged to meet the preset block chain recording condition; if the quotient value is not greater than the preset block chain recording parameter threshold value, the occupation ratio of the resource expected result audit block chain nodes which approve the resource expected result in all the resource expected result audit block chain nodes is less, and accordingly, the returned information is judged not to meet the preset block chain recording condition. The method for judging the quotient of the number of the returned information passing the audit divided by the total number of the returned information is more accurate than the method for judging the number of the returned information passing the audit, and can prevent misjudgment caused when a large number of resource expected results audit block chain link points fail (for example, the audit block chain link points and an external communication interface are hijacked) and cannot participate in the audit.

In one embodiment, after the step S5 of determining whether the returned information satisfies the preset blockchain recording condition, the method includes:

s51, if the returned information does not meet the preset block chain recording condition, sending a reason acquisition instruction to a resource expected result auditing block chain link point of which the returned information is not approved, wherein the reason acquisition instruction is used for indicating the resource expected result auditing block chain link point to send the reason of not approved to the designated terminal;

s52, receiving the reason that the audit sent by the resource expected result audit block chain node is not passed;

s53, judging whether the reason of the failure of the verification exists in a preset reason list or not;

and S54, if the reason for the failure of the audit exists in a preset reason list, the expected result of the resource is not allowed to be recorded into the second block chain network, a reminding message for the failure of the audit is generated, and the reason for the failure of the audit is attached to the reminding message.

As described above, it is achieved that logging of the expected result of the resource into the second blockchain network is not allowed. And if the return information does not meet the preset block chain recording condition, indicating that the expected result of the resource is not approved and cannot be recorded into the second block chain network. However, in order to utilize error tracing to determine the reason why the resource is not passed so as to correct the reason in time, the method also adopts the step of sending a reason acquisition instruction to the link point of the resource expected result auditing block, the returned information of which is not passed by auditing; receiving the reason that the audit sent by the resource expected result audit block chain node fails; and generating reminding information of which the audit fails, and attaching the reason of the failed audit to the reminding information so as to correct the expected result of the failed resource.

In one embodiment, the extracting the first data from the preset first blockchain network, wherein the specified terminal is a blockchain node of both a pre-constructed first blockchain network and a pre-constructed second blockchain network, the first blockchain network includes at least a blockchain node providing the resource expected calculation usage data, and the second blockchain network includes at least the step S1 of reviewing the blockchain node of the resource expected result, and includes:

s001, creating a block chain class by using a Go language, giving a designated parameter to the block chain class to obtain a created block, and setting a hash value of a previous block to be 0 in the created block;

s002, generating other blocks based on the founding block, wherein the other blocks record hash values of a previous block;

and S003, taking a preset terminal as a block chain node of a second block chain network, thereby constructing the second block chain network.

As described above, building the blockchain network is achieved. The language for creating the blockchain class may be any feasible language, such as JAVA, C + +, go language, etc., and the C + +, go language is preferred in this embodiment, so as to optimize the blockchain class. The class of the blockchain is a definition of the blockchain, and instantiating the class of the blockchain is to determine specific parameters of the blockchain, so as to obtain a first block (created block) and use the first block as a basis for generating other blocks. Since the created block is the first block, there is effectively no previous block, so the hash value of the previous block is set to 0 in the created block. And generating other blocks based on the created blocks, wherein the other blocks are recorded with the hash value of the previous block, so that all the blocks are closely connected and the data is prevented from being tampered. The preset consensus mechanism of the second blockchain network may be any consensus mechanism, such as a workload certification mechanism, a rights and interests certification mechanism, a byzantine fault tolerance mechanism, a stock authorization certification mechanism, and the like, and the stock authorization certification mechanism is preferred in this embodiment. Further, the building method of the first block chain network may be the same as that of the second block chain network, or may be different from that of the second block chain network.

In one embodiment, the method for extracting the first data from the preset first blockchain network includes, by the designated terminal, prestoring a virtual machine image and a blockchain container image, where the designated terminal is both a blockchain node of the first pre-constructed blockchain network and a blockchain node of a second pre-constructed blockchain network, the first blockchain network includes at least a blockchain node providing the resource-expected computation-usage data, and the second blockchain network includes at least a blockchain node for resource-expected result auditing before step S1, the method includes:

s011, receiving a request of joining a second block chain network sent by an application terminal, wherein the request of joining the second block chain network is accompanied with identity information of the application terminal;

s012, judging whether the identity information of the application terminal is in a preset allowed adding list;

s013, if the identity information of the application terminal is in a preset allowed join list, sending the virtual machine mirror image and the block chain node container mirror image to the application terminal;

s014, acquiring the IP address and the communication port of the application terminal;

s015, to apply for the terminal to send the information of the IP address and the communication port of all block chain nodes of the second block chain network of prestoring to and send to all block chain nodes of the second block chain network the information of the IP address and the communication port of applying for the terminal, thus will apply for the terminal to join in the second block chain network, wherein apply for the terminal and have installed and start in the virtual machine mirror image block chain node container mirror image.

As described above, the second blockchain network is rapidly deployed by using the virtual machine image and the block chain link point container image. The virtual machine image is used for providing a basic operation environment, such as an environment for operating a blockchain node container image, a programming language operation environment or a basic toolkit. The container mirror image of the block chain node is stored with data such as a public ledger (for example, an existing approval record of the current approval system is converted into a public ledger), and the like, and is used for enabling the terminal to have basic conditions for becoming the block chain node (for example, information such as IP addresses of other block chain nodes needs to be acquired, and information such as IP addresses of the terminal is informed to other block chain nodes, and then the terminal can complete joining the block chain network) after the container mirror image of the block chain node is installed and started. And informing all block chain nodes of a second block chain network of the IP address and the communication port of the application terminal, and sending the information of the IP address and the communication port of the application terminal to all block chain nodes of the second block chain network, thereby realizing rapid addition of the application terminal into the second block chain network. According to the method and the device, the node block chain deployment speed is increased and the decentralization of the block chain is maintained by presetting the virtual machine mirror image and the block chain node container mirror image. Further, the method for adding a blockchain node to the first blockchain network may be the same as the second blockchain network or may be different from the second blockchain network.

According to the resource expected result auditing method based on the block chain, first data are extracted from a preset first block chain network; acquiring second data, judging whether the resources are normal according to the second data, and generating a resource expected result according to the first data; receiving return information of a plurality of resource expected result auditing block chain link points for auditing the resource expected results; and if the return information meets the preset block chain recording condition, recording the expected resource result into the second block chain network. Therefore, the defects of low efficiency, opaque process, low information safety and the like of the traditional technology are overcome.

Such as financial, and expected budget. Wherein the first blockchain network and the second blockchain network may be public chains, alliance chains, or private chains. The public ledger of the first blockchain network is used to maintain data that provides an anticipated calculated usage of the resource, such as a division expense plan made by the division, and the like. And the public ledger of the second block chain network is used for storing the expected result of the approved resource. The designated terminal is simultaneously located in the first block chain network and the second block chain network, so that a public account book of the first block chain network and a public account book of the second block chain network are simultaneously provided, data sources of the whole process of checking the first data, the generated resource expected result and the resource expected result are real and credible, and information safety is improved. Wherein the block link points of the first block chain network may record data used to generate the resource expectation result into a public ledger of the first block chain network. Therefore, in the method for auditing the expected result of the resource based on the blockchain, the first data is derived from the public ledger of the first blockchain network and is difficult to be tampered, so that the problem of questioning the reliability of the data in the traditional technology is solved; and the auditing of the expected result of the resource is realized in the second block chain network and recorded in the second block chain network, so that the technical effects of credibility of the expected result of the resource, hierarchical management and possible error tracing are realized.

As described above in unit 20, the second data of the resource collected in real time is obtained, and according to the formula:

h (t) = min (G (t), m), wherein

the differential function of the difference function to the time is adopted, min refers to a minimum function, t refers to the time, and m refers to a preset error parameter value larger than 0; acquiring a first time length of the function H (t) on a time axis when the function H (t) is not equal to m and a second time length when the function H (t) is equal to m, and according to a formula: normal time ratio = the first time length/(the first time length + the second time length), the normal time ratio is calculated, and whether the normal time ratio is greater than a preset ratio threshold is judged; if the normal time ratio is larger than a preset ratio threshold value, according to the first data, utilizing preset resource expectationAnd (4) an algorithm for generating a resource expected result. The function H (t) is used for representing the condition of the second data, and when the value of the function H (t) is m, the function H (t) indicates that the value of the second data is overlarge and is in an abnormal state; when the value of the function H (t) is not m, the value of the second data is normal and is in a normal state, the normal time ratio is calculated according to the value, and whether the normal time ratio is larger than a preset threshold value or not is judged; and if the normal time ratio is greater than a preset ratio threshold, generating a resource expectation result by using a preset resource expectation algorithm according to the first data. Wherein the first data is used to generate the resource expectation result, and thus the resource expectation result can be generated. According to the first data, a preset resource expectation algorithm is used to generate a resource expectation result, which may be any manner, for example: dividing income data and expenditure data from the first data; judging whether the income data and the expenditure data are credible or not; if the income data and the expenditure data are credible, respectively recording as credible income and credible expenditure; counting the credible income and credible expense so as to obtain credible total income and credible total expense; generating a resource expectation result comprising the trusted total revenue and the trusted total expenditure.

As described in the above unit 30, the resource expected result is sent to a plurality of resource expected result auditing block chain nodes in the second block chain network, and a plurality of resource expected result auditing block chain nodes are required to audit the resource expected result. The resource expected result auditing blockchain node may be all blockchain nodes in the second blockchain network or may be part of blockchain nodes. Sending the resource expected result to a plurality of resource expected result auditing block chain nodes in the second block chain network, and requiring the plurality of resource expected result auditing block chain nodes to audit the resource expected result, for example, the process includes: acquiring a plurality of resource expected result audit block chain nodes selected according to a preset share authorization certification mechanism in the second block chain network; sending an audit request to all the chain nodes of the resource expected result audit block, and requiring the chain nodes of the resource expected result audit block to send reply information; receiving reply information sent by the link node of the resource expected result audit block, and recording link points of the resource expected result audit block, which are willing to be audited, of the reply information as final link nodes of the resource expected result audit block; and sending the resource expected result to a plurality of final resource expected result auditing block chain nodes, and requiring the plurality of final resource expected result auditing block chain nodes to audit the resource expected result.

As described in the above unit 40, return information of auditing the resource expected results by multiple resource expected result auditing block chain nodes is received, where the return information includes that the auditing is passed or the auditing is not passed. The link points of the audit block of different resource expected results are not necessarily identical in audit mode, so the audit results may be different, and are respectively audit passed or audit not passed. In order to avoid misjudgment, return information of the resource expected result by the link points of the plurality of resource expected result auditing blocks is received and comprehensively considered to determine whether the resource expected result is recorded into a public account book of the second block chain network.

As described in the above-mentioned unit 50, it is determined whether the returned information satisfies a preset blockchain recording condition. The mode of judging whether the returned information meets the preset block chain recording condition can be any mode, for example, when the number of the returned information passing the audit reaches the condition of a preset threshold value, the preset block chain recording condition is judged to be met; or when the ratio of the number of the returned information which passes the audit to the number of all the returned information is larger than the preset ratio threshold, judging that the preset block chain recording condition is met.

As described in the foregoing unit 60, if the return information meets the preset condition for recording the blockchain, the expected result of the resource is recorded into the second blockchain network. And if the return information meets the preset block chain recording condition, most of the audit block chain nodes in the second block chain network accept the expected resource result, and therefore the expected resource result is recorded into the second block chain network. So that a blockchain node in a second blockchain network can learn the expected result of the resource from the second blockchain network.

In one embodiment, the resource is a resource of a specified object, the first data includes predicted resource increase amounts and predicted resource consumption amounts of a plurality of sub-objects of the specified object, and the resource expected result obtaining unit 20 includes:

As described above, generation is achievedThe resource expects a result. The first data of the present application includes, for example, a department expected income and a department expected expenditure of a plurality of departments, and the resource expected result can be generated based on the department expected income and the department expected expenditure. Wherein due to the different importance of different departments, the corresponding department budget is also affected accordingly. Accordingly, the present application employs an importance level parameter p ₁ 、p ₂ …、p _n To represent the degree of importance of the department, and according to the formula:

Wherein the expected revenue of the first department to the nth department is A ₁ 、A ₂ …、A _n The predicted payout of the first division to the nth division is B ₁ 、B ₂ …、B _n . Therefore, the resource expectation is more targeted so as to ensure the resource expectation of important departments.

Accordingly, the check block chain node can make a decision whether to add the resource expected result into the block chain network according to the plurality of resource expected results selected by the share authorization certification mechanism. In addition, in order to prevent the inaccurate final decision caused by the fact that part of the link points of the audit block of the expected result of the resource cannot participate in the audit (for example, the link nodes of the audit block of the expected result of the part of the resource are not started, or the communication fails, etc.), the embodiment also adopts a mode of sending the audit request in advance to determine the link nodes of the audit block willing to be audited, and to mark the link nodes as the link nodes of the audit block of the expected result of the final resource, and sends the preset specified transfer route to a plurality of the link nodes of the final audit block, thereby reducing unnecessary network overhead (the overhead of sending the audit request is far less than that of sending the expected result of the resource), and ensuring the accuracy of subsequent judgment (excluding the nodes which cannot participate in the audit).

And if the return information does not meet the preset block chain recording condition, indicating that the expected result of the resource is not approved and cannot be recorded into the second block chain network. However, in order to utilize error tracing to determine the reason why the resource is not passed so as to correct the reason in time, the method also adopts the step of sending a reason acquisition instruction to the link point of the resource expected result auditing block, the returned information of which is not passed by auditing; receiving the reason that the audit sent by the resource expected result audit block chain node fails; and generating reminding information of which the audit fails, and attaching the reason of the failed audit to the reminding information so as to correct the expected result of the failed resource.

Since the created block is the first block, there is virtually no previous block, so the hash value of the previous block is set to 0 in the created block. And generating other blocks based on the created blocks, wherein the other blocks are recorded with the hash value of the previous block, so that all the blocks are closely connected and the data is prevented from being tampered.

The container mirror image of the block chain node is stored with data such as a public ledger (for example, an existing approval record of the current approval system is converted into a public ledger), and the like, and is used for enabling the terminal to have basic conditions for becoming the block chain node (for example, information such as IP addresses of other block chain nodes needs to be acquired, and information such as IP addresses of the terminal is informed to other block chain nodes, and then the terminal can complete joining the block chain network) after the container mirror image of the block chain node is installed and started. And then informing all block chain nodes of the second block chain network of the IP address and the communication port of the application terminal, and sending the information of the IP address and the communication port of the application terminal to all block chain nodes of the second block chain network, thereby realizing the rapid addition of the application terminal into the second block chain network.
