It should also be understood that the term "and/or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.
It should be understood that although the terms first, second, third, etc. may be used herein to describe various information, these information should not be limited to these terms. These terms are only used to distinguish one type of information from another. For example, the first information may also be referred to as second information, and similarly, the second information may also be referred to as first information, without departing from the scope of the present specification. The word "if" as used herein may be interpreted as "at … …" or "when … …" or "in response to a determination", depending on the context.
It should be noted that: in other embodiments, the steps of the corresponding methods are not necessarily performed in the order shown and described herein. In some other embodiments, the method may include more or fewer steps than those described herein. Moreover, a single step described in this specification may be broken down into multiple steps for description in other embodiments; multiple steps described in this specification may be combined into a single step in other embodiments.
The present specification aims to provide a method for processing the offset of financial bookings accrued in a blockchain, and a device and equipment using the method.
In one embodiment, when a user needs to offset a certain financial accounting that is credited in a blockchain and an associated accounting belonging to the same business as the accounting, a request for offsetting the financial accounting for the accounting and the associated accounting belonging to the same business as the accounting (called target accounting) can be initiated by the user (called accounting offsetting party) through a client.
And the accounting node or the accounting impulse node in the block chain can respond to the financial accounting impulse request after receiving the financial accounting impulse request.
Specifically, it may be determined whether the billing impulse party has the impulse authority of the target billing. For a certain accounting, the original accounting party or the trusted third party of the accounting is generally only allowed to carry out reimbursement processing on the accounting so as to ensure the data security of the accounting and avoid malicious reimbursement of the accounting. In this case, it may be determined first whether the billing impulse party originating the impulse request has the impulse rights of the target billing. If the billing impulse party is the original billing party or a trusted third party to the billing, it may be determined that the billing impulse party has the impulse rights to the billing. The trusted third party may include: a superior organization of the billed primary biller, a superior leader of the billed primary biller, other trusted authorities, or any organization or individual who has been authorized to reimburse the billings.
After determining that the accounting impulse party has the impulse authority of the accounting, the accounting node or the accounting impulse node can call accounting impulse logic declared in an intelligent contract issued on the blockchain to carry out impulse processing on the target accounting certified in the blockchain.
In the above technical solution, when an accounting impulse and cancellation party initiates an accounting impulse and cancellation request for a certain accounting stored in a block chain, the accounting impulse and cancellation party can be verified for impulse and cancellation authority by calling corresponding logic in an intelligent contract issued on the block chain, and when it is determined that the accounting impulse and cancellation party has the impulse and cancellation authority of the accounting, the accounting is processed for impulse and cancellation. Therefore, when the offset processing is carried out on the accounting of the evidence stored in the block chain, the data security and the data accuracy of the accounting on the block chain can be ensured.
The block chain described in this specification may specifically include any type of block chain network; for example, in practical applications, any one of a public chain, a private chain, or a federation chain may be employed.
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a block chain-based financial accounting cancellation method according to an embodiment of the present invention. As shown in fig. 1, there is provided a block chain-based financial accounting cancellation method, the method comprising the steps of:
step S102: receiving a financial accounting cancellation request initiated by an accounting cancellation party and aiming at target accounting for the evidence stored in the blockchain;
step S104: in response to the financial billing reimbursement request, determining whether the billing reimburser has reimbursement authority for the target billing;
step S106: and if the accounting reimbursement party has the reimbursement authority of the target accounting, invoking accounting reimbursement logic declared in the intelligent contract issued on the block chain, and performing reimbursement processing on the target accounting.
Since the data stored in the blockchain has the property of being not tampered, the data is stored in the blockchain for data storage. In this embodiment, the accounting may be credited in the blockchain.
When the accounting and canceling party needs to carry out canceling processing on the target accounting which is stored in the block chain, a canceling request for canceling the target accounting can be initiated by a client used by the accounting and canceling party.
The accounting node or accounting cancellation node in the blockchain may respond to the cancellation request after receiving the cancellation request.
Preferably, it may be determined whether the billing impulse party has the impulse authority of the target billing first.
And if the accounting reimbursement party has the reimbursement authority of the target accounting, invoking accounting reimbursement logic declared in the intelligent contract issued on the block chain, and performing reimbursement processing on the target accounting.
Wherein, the accounting reimbursement logic may specifically be program code declared in the intelligent contract that is associated with execution logic that reimburses accounting. Scale, some procedure methods or functions that are available for invocation.
In one embodiment, the intelligent contract may also declare authority verification logic for the billing impulse party. In this case, the authority verification logic declared in the intelligent contract may be invoked to determine whether the billing impulse party has the impulse authority of the target billing.
Wherein the authority verification logic may specifically be program code declared in the intelligent contract relating to execution logic verifying the impulse authority of the accounting impulse party.
It should be noted that the above-described intelligent contract for performing reimbursement processing on the account and the intelligent contract for verifying reimbursement authority of the reimbursement party may be integrated into one intelligent contract to be deployed on the block chain, or may be deployed on the block chain as two different intelligent contracts, which is not limited in this specification.
In another preferred embodiment, the impulse request for the target accounting initiated by the accounting impulse party through the client used by the accounting impulse party may include the user identification of the accounting impulse party, so that it may be determined whether the accounting impulse party has the impulse right of the target accounting based on the user identification of the accounting impulse party.
Specifically, the user identification of the billing impulse party can be matched with the user identification of the original billing party of the target billing to determine whether the billing impulse party is the original billing party of the target billing. If the user identification of the accounting impulse party is the same as the user identification of the original accounting party of the target accounting, the accounting impulse party can be determined to be the original accounting party of the target accounting, so that the accounting impulse party can be determined to have the impulse authority of the target accounting.
Alternatively, the user identification of the billing impulse party may be matched with the user identification of the trusted third party to determine whether the billing impulse party is a trusted third party. If the user identity of the billing impulse party is the same as the user identity of the (certain) trusted third party, the billing impulse party may be determined to be the trusted third party, and thus the billing impulse party may be determined to have the impulse rights of the target billing.
Accordingly, if it is determined that the billing impulse party is neither the original billing party nor the trusted third party for the target billing, it may be determined that the billing impulse party does not have the impulse rights for the target billing. In this case, the target accounting may not be subjected to subsequent offset processing.
The user identification can be an individual identification number or an organization code of a trusted third party; alternatively, the user identifier may be a user number assigned to an individual, a business, an organization, a business, or a department in an organization, and the user numbers assigned to different users are different, which is not limited in this specification.
In another embodiment, when the accounting is deposited in the blockchain, the original accounting party or the user of the trusted third party having the charge-off authority of the accounting can be identified in the blockchain to be deposited correspondingly.
After receiving the reimbursement request for the target account including the user identifier of the accounting reimbursement party, the user identifier of the accounting reimbursement party may be matched with the user identifier corresponding to the target account. If the user identification of the accounting reimbursement party is the same as a certain user identification corresponding to the target accounting, the accounting reimbursement party can be determined to have the reimbursement authority of the target accounting.
In a certain embodiment, the billing impulse and sales party initiates an impulse and sales request for the target billing through a client used by the billing impulse and sales party, where the impulse and sales request may include a billing identifier of the target billing, so that it may be determined whether the target billing has been credited in the blockchain, and then, when it is determined that the target billing has been credited in the blockchain, it is determined whether the billing impulse and sales party has the impulse and sales authority of the target billing, so as to avoid an invalid operation when the target billing has not been credited in the blockchain, and reduce device resource consumption.
Specifically, when the accounting is stored in the blockchain, the accounting identifier of the accounting can be correspondingly stored in the blockchain at the same time.
After receiving the reimbursement request for the target accounting containing the accounting identification of the target accounting, the accounting identification of the target accounting can be matched with the accounting identification of each accounting which is already stored in the blockchain. If the accounting identification of the accounting is the same as the accounting identification of a certain accounting which is already stored in the block chain, the accounting corresponding to the accounting identification can be determined to be stored in the block chain, and the accounting is determined as the target accounting. Thereafter, it may be determined whether the billing impulse party has impulse rights for the target billing.
Accordingly, if it is determined that the block chain does not store the accounting corresponding to the accounting identifier, it is no longer necessary to determine whether the accounting impulse party has the impulse right of the target accounting.
The accounting identifier is any character string which can uniquely represent an accounting in the block chain system. For example, the billing identifier may be a hash value obtained by performing a hash calculation on the billing data; alternatively, the hash value may be obtained by performing a hash calculation on unique information (for example, a billing number or a combination of an organization code and a billing number) in the billing data.
For example, assuming that only accounting 1 and accounting 2 are stored in the block chain, and the accounting identifier of accounting 1 is accounting identifier 1, and the accounting identifier of accounting 2 is accounting identifier 2, after receiving a reimbursement request for accounting 1 including accounting identifier 1, it may be determined that accounting 1 corresponding to accounting identifier 1 is stored in the block chain according to the above assumption, and determine accounting 1 as the target accounting; after receiving the reimbursement request for the accounting 3 including the accounting identifier 3, determining that the accounting 3 corresponding to the accounting identifier 3 is not stored in the block chain according to the assumption; and so on.
In one embodiment, since the data stored in the blockchain has the property of being not tampered, the state of the target accounting can be updated from the valid state to the invalid state, so as to realize the reimbursement process of the target accounting.
For example, when the target accounting is stored in the blockchain, a state identifier for representing that the target accounting is valid may also be set for the target accounting, that is, the state of the target accounting is a valid state at this time. Subsequently, when it is determined that the reimbursement processing needs to be performed on the target accounting, the state identifier of the target accounting can be updated to the state identifier representing that the target accounting is invalid, that is, the state of the target accounting is updated from the valid state to the invalid state.
The status identifier may specifically be a specific byte or a boolean value set for accounting. This is not a limitation of the present specification.
In another embodiment, the financial billing reimbursement request carries correct billing data for the reimbursement to be billed; the intelligent contract also declares the impulse accounting logic; in this case, based on the correct billing data of the to-be-charged-and-reimbursed billing and the billing data of the target billing, the charging-and-reimbursed billing logic declared in the intelligent contract is called, and the charging-and-reimbursed billing corresponding to the target billing is generated.
Wherein the reimbursement billing logic may be specifically program code declared in the intelligent contract relating to reimbursement billing execution logic for the billing reimbursement party.
Wherein the reimbursement bookkeeping refers to a correct bookkeeping corresponding to the target bookkeeping (as a wrong account in the accounting bookkeeping), and the correct bookkeeping corresponds to an accounting entry in red writing and/or an accounting entry in blue writing in the accounting bookkeeping.
And acquiring accounting data of the target accounting before calling the reimbursement accounting logic declared in the intelligent contract and generating reimbursement accounting corresponding to the target accounting. In one embodiment, billing viewing logic is also declared in the intelligent contract, in which case the billing viewing logic declared in the intelligent contract is invoked to obtain billing data for the target billing based on the billing identification of the target billing. The billing data for the target billing may be stored in the blockchain or in a billing system outside the blockchain.
Wherein, the correct accounting data for the accounting to be charged and sold comprises: accounting account, debit subject, credit subject, debit generation amount, credit generation amount, accounting summary, accounting date, accounting organization or accounting person and the like; the billing data for the target billing may include: the system comprises a billing identification, a billing account, a debit subject, a credit subject, a debit generation amount, a credit generation amount, a billing abstract, a billing date, a service identification of a service to which the target billing belongs, a service serial number of the service to which the target billing belongs, an organization or individual to which the billing belongs, and the like.
If the target account belongs to one of the generated accounting details belonging to the same service (event), when the target account is offset, it may be necessary to offset other account details belonging to the same service (event) as the target account.
In one embodiment, the billing data of the target billing comprises a service identifier and/or a service flow number, and we can obtain other billing details belonging to the same service (event) as the target billing through the service identifier and/or the service flow number. The way to obtain billing data for other billing details belonging to the same service (event) as the target billing is the same as the way to obtain billing data for the target billing.
After acquiring the correct billing data of the to-be-reimbursed billing and the billing data of the target billing (and other billing details belonging to the same service (event) as the target billing), compliance verification is required for the correct billing data of the to-be-reimbursed billing and the billing data of the target billing (and other billing details belonging to the same service (event) as the target billing) to determine whether the correct billing data and the billing data of the target billing match.
In one embodiment, compliance verification logic for reimbursement accounting is also declared in the smart contract; in this case, based on the correct billing data of the reimbursement bookings to be charged and the target billing data, the compliance verification logic declared in the intelligent contract is invoked to determine whether the correct billing data and the target billing data match.
Wherein the billing viewing logic may specifically be program code declared in the intelligent contract that is related to the billing viewing execution logic for the billing impulse party.
Wherein the compliance verification logic may specifically be program code declared in the intelligent contract that executes logic related to comparing the correct billing data for the to-be-charged billing with the billing data for the target billing. The compliance verification logic includes: whether the organization or the person to which the accounting belongs in the correct accounting data of the to-be-reimbursed accounting is the same as the organization or the person to which the accounting belongs in the accounting data of the target accounting or not; if the debit and credit accounting method in the multiple accounting method is used, whether the correct accounting data for the debiting and debiting accounting satisfy the debit and credit balance is checked; and so on.
If it is determined that the correct billing data matches the target billing with billing data for the target billing and other billing details pertaining to the same service (event) as the target billing, then the reimbursement billing logic declared in the intelligent contract is invoked to generate reimbursement billing corresponding to the target billing and other billing details pertaining to the same service (event) as the target billing. And the reimbursement accounting comprises reimbursement of the target accounting and red word accounting of accounting details of the same business as the target accounting and/or blue word accounting representing correct accounting.
Reimbursement billing (including reimbursement of the target billing and red-word billing for other billing details pertaining to the same business as the target billing and/or one or more blue-word billing for proper billing) as general billing also requires evidence to be deposited on the blockchain.
