Description

{Account Process System based on Blockchain}

The present invention relates to a blockchain-based accounting processing system, and more specifically, a blockchain that is a distributed ledger technology designed to ensure the reliability of transaction records by recording, verifying, and storing transaction information jointly by system participants without a centralized institution. Through a technology, it is difficult to change a transaction once recorded, so it is possible to exclude the possibility of mistakes and forgery/falsification of the original data, and the blockchain-based one that enables real-time calculation of the status of each account, such as assets, liabilities, and cash It is related to the accounting processing system.

The double bookkeeping developed in the 1490s allows one transaction record to be written in both debit and credit simultaneously by a certain rule, making it easy to verify consistency.

This double bookkeeping became the basis of modern accounting and contributed greatly to the development of the capital market by facilitating corporate investment by capitalists based on accurate accounting.

However, even with double bookkeeping, forgery/falsification of information is possible, so an accounting audit system and an accounting corporation have appeared to rule out this, and the accounting industry has been born.

Currently, all companies over a certain size are paying a huge amount for accounting.

The financial analysis method that analyzes the soundness, profitability, stability, and activity of a company's financial structure in the related art is difficult to distinguish whether a company is insolvent by using only a schematic financial analysis method due to the fact that the company's distributed accounting and book manipulation are widely performed. It is quite difficult.

In fact, companies that have been judged as superior companies by actual financial analysis broke out within a few months, and the fact that accounts for fraudulent accounting was delayed, and invested in financial statements made with imaginary numbers and suddenly became insolvent, causing investors to suffer huge losses. There are many examples.

In this respect, it is meaningless to identify the soundness of the financial structure, accounting transparency, and management transparency of the company's financial structure by using the traditional financial analysis method that is too simple and general. In particular, non-professionals who do not have accounting knowledge can analyze the financial situation of the company. There was a problem of not having the opportunity for in-depth evaluation even if I wanted to.

Republic of Korea Patent Publication No. 10-2008-0033757

The present invention has been devised to solve the above-mentioned problems, and once through the blockchain technology, which is a distributed ledger technology designed to ensure the reliability of transaction records by system participants jointly recording, verifying, and storing transaction information without a centralized institution. Recorded transactions are difficult to change, so it is possible to exclude the possibility of mistakes and forgery/falsification of the original data, and the status of each account such as assets, liabilities, and cash can be calculated in real time, so that the calculation results can be trusted by anyone.

2 is a view for explaining the transaction process of the seller and the buyer through the blockchain-based accounting processing system according to an embodiment of the present invention,
3 to 9 are diagrams for explaining a state in which a transaction process performed through a blockchain-based accounting processing system according to an embodiment of the present invention is displayed in a web browser on a terminal,
10 to 27 are diagrams for explaining an example of a transaction process in progress through a blockchain-based accounting processing system according to an embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to easily describe those skilled in the art to which the present invention pertains.

First, the accounting for the purpose of inflating profits or assets for the purpose of making the company's business performance look better than it actually is, for the purpose of passing the listing examination in the process of preparing IPO (Initial Public Offering) of unlisted companies It may happen.

Frequently, information manipulated through such accounting accounting leads to damage in the judgment process of investors.

Investors set the standard of judgment for companies and make decisions based only on socially disclosed information.

However, in the current system, the company's financial information can be disclosed only through a separate verification and reorganization process. This is the past information that has passed 1~3 months, and the effectiveness of the information decreases, leading to the failure of investors to respond to the market.

Startups and ICO (Initial Coin Offering) companies in the early stage of establishment are not subject to external exemption because they are not regulated, and thus corporate and financial information are not properly disclosed, i.e., there is a lack of feedback on information related to investment and even information provided Transparency is not secured.

In order for managers to make flexible decisions about changing market conditions, it is necessary to have accurate information about the company at the present time, but the information collected in real time within the current system is temporarily unsynthesized and verified. This can lead to negative consequences.

In the case of small and medium-sized enterprises, the lack of awareness of internal control and the lack of systematic control procedures are very high, and the risks associated with the use of funds and the acts of betrayal are very high.

With globalization, the number of business partners at home and abroad is rapidly increasing, and the ways in which transactions are diversified are increasing. As a result, the review period for accounting audits is increasing, investment manpower and costs are increasing, and the rapidly increasing amount of ICO financing and the number of companies are increasing. Despite this, accounting and tax processing are not being carried out properly due to the lack of precise regulations.

In order to evaluate the financial health of a company in the current system, users of corporate information existing in/outside the company, such as financial institutions, government agencies, investors, and managers, will evaluate based on financial information of at least several months and up to a year ago. .

This approach reduces the soundness of a growing company, negatively affecting additional funding or investment, and in the case of a declining company, financial soundness is overestimated, resulting in huge losses for investors and creditors. have.

Financial information focuses on judging a company's bona fide, but the importance of non-financial information such as internal control, governance, social and environmental factors that are not revealed in accounting figures is emerging. The financial and non-financial information must be comprehensively understood.

Due to the operability of illegal elements such as secondary processing and concealment of corporate financial information and the lack of systematic organization of information, the burden on the review and management process of tax authorities is constantly increasing.

As the introduction of blockchain technology spreads, many changes are expected to occur in the accounting industry.

In the blockchain, a distributed ledger technology designed to ensure the reliability of transaction records by jointly recording/verifying/storing transaction information without a centralized institution, transactions recorded once are extremely difficult to change, making mistakes and forgery/falsification of the original data It is possible to exclude the possibility of, and the status of each account, such as assets, liabilities, and cash, can be calculated in real time, so that the result of calculation can be trusted by everyone.

As an accounting solution utilizing blockchain, it is possible to secure the reliability of transaction information by removing the individuality and possibility of manipulation of records in the existing double entry accounting system, and in the process of transaction recognition as data about contracts and transaction details are stored in the block. The scope of automatic verification increases, and real-time accounting is processed to facilitate constant monitoring.

As the accounting solution using blockchain, it is possible to derive aggregated data on the confirmation situation in real time, which reduces the difficulty of the audit process performed in a specified period as the basis for regular audits.

It is an accounting solution that utilizes blockchain, provides information for intuitive understanding by comparing and analyzing companies in the blockchain ecosystem and the real economy ecosystem, and exchanges and applies each analysis method to effectively predict future value and business performance. And providing a reasonable estimate of the growth of the company, including projected funding needs.

Providing the judgment criteria for transparency of corporate financial information by numerically providing the reliability and verification of information calculated through the accounting solution using blockchain, including non-financial information such as corporate governance and social impact Disclosing the basis for the company's judgment on sustainable management.

The advent of blockchain is not an exaggeration to say that it is a technology that will revolutionize the accounting field, and the blockchain itself is a distributed ledger system, that is, a system in which multiple books (nodes) store the ledger itself in which transactions are recorded is a blockchain. to be.

This can be called triple-entry accounting in the sense that the record of the transaction is recorded in both accounts and the entire book itself is recorded in a distributed book.

With the application of blockchain to such accounting information system (AIS), all digital forms of asset authentication, recording, registration, storage, transaction and payment can be made through blockchain technology.

These advantages do not require intermediary participants, the process is efficient and transparent, the cost is reduced, the data is stored very securely, you can benefit from the reduction of accounting errors and accounting irregularities, and a new accounting fraud prevention system. I can make it.

Blockchain accounting system is a solution in which a blockchain module and an accounting information system (AIS) are interconnected.

In other words, the transaction information includes all the basic information that can support the accounting amount, and stores and manages the transaction information in blocks.

The accounting information system (AIS) is designed to be connected to the blockchain and automatically extract the information necessary for accounting processing from the block.

When blockchain accounting system is applied to corporate accounting, its effectiveness can be found in internal accounting.

First, the company collects the accounting books of the branches and prepares separate financial statements of the head office, consolidates the accounting books of the subsidiaries, and even consolidates the financial statements. Need something

The main concern of the head office is to verify that there are no errors or intentional errors in the data of the accounting books to be collected.

The blockchain accounting system can be a safety device that can secure reliability for this.

Second, it is possible to thoroughly establish the internal control of the company through the blockchain accounting system.

In creating account books, if multiple people are jointly responsible for the contents of records through the blockchain, the possibility of intentional errors will decrease.

For example, it would be difficult to modify the account balance on the system without any basis or transaction, and it would be more difficult to intentionally inflate inventory amounts or adjust sales.

In addition, the transaction history stored in the block may include detailed information such as time information, approval information, and the number of approvals of the transaction content, not just a document, and an internal control point that can detect fraud can be designed using this.

Third, it will increase work efficiency.

Accounting teams of many companies go through the process of checking the account balance through Account Reconciliation, but books linked by blockchain will not need to do this.

Finally, external auditors and tax authorities are granted a KYC authentication key to identify stored transactions in the process of external auditors auditing financial statements created in a blockchain-based accounting system or in the process of regulation by tax authorities. Blockchain linked to financial statements can be viewed.

The information stored on the blockchain will be used as a reliable audit evidence that includes confirmation and approval of transactions, not just documents, and will greatly reduce the burden on the tax authorities and improve regulatory convenience.

The block chain accounting system stores and manages key accounting information on the blockchain, and includes a three-type bookkeeping accounting program through which the key documents such as contracts, P/Os, issue certificates, and transaction details are stored and managed through the blockchain. And, it includes the function of securing the reliability of the transaction details using the smart contract of the trading party & third party (accounting auditor, etc.).

Blockchain accounting systems can provide backup and recovery, availability and privacy protection solutions while optimizing the cost of storing data on the blockchain, while data owners can access key data such as transaction history from the time of contract to payment. It can be directly managed and completely controlled by storing it externally by blockchain connection.

This data can be stored via a distributed decentralized database (such as IPFS) or a classic RDBMS (PostgreSQL, Oracle, SQL Server, etc.).

Transactions will take place until the point of delivery and payment of the blockchain-based accounting processing system, and transactions can be stored and managed in blocks, and the data stored in the blocks is mutually authorized during the transaction. The transaction contents up to the point of confirming and approving the transaction contents are stored in the block.

The KYC authentication key that identifies the trading party is granted, so that mutual identification is possible and the authority to approve the transaction is granted.

A digital signature attaches a cryptographic seal to a document, providing tamper-proofing, while also providing evidence that a particular party has signed it.

It is designed to allow third parties to approve the contents of the transaction by granting the authority to be signed by the trading party to the designated representatives (managers, transaction managers, etc.) inside the company and also to authorized accountants and government agencies.

Through this, it is possible to derive the consensus method called trust verification method through the act of increasing the reliability of data stored in the blockchain.

The blockchain accounting system is designed to analyze the transaction history (name of transaction, amount, etc.) stored in the block and map it to the account subjects set in the accounting system, and automatically perform accounting.

In addition, since the acquisition information of fixed assets and deposit information/loan information are stored in the block, such accounting adjustments such as depreciation cost calculation, interest income calculation, and interest cost calculation are automatically calculated. It is possible to provide analysis data for computational audit purposes by analyzing the patterns derived through.

Therefore, the blockchain accounting system provides reliable financial information to investors because it is almost impossible to forge/tamper by storing transaction information on the blockchain, and it becomes transparent accounting processing by the evidence of external auditors and customers.

The internal control management system and artificial intelligence (AI) automatically inform managers immediately when internal abnormalities occur, blocking embezzlement and internal transaction risks, and by providing reliable financial information to government agencies, the government is transparently taxed. Based on the information, a fair tax policy can be established and implemented.

In addition, due to the accuracy of transaction details, accounting audit efficiency increases, saving time and money, and automating the accounting process for transactions reduces the administrative burden, and monitoring is always possible due to time data recording. Based on this, managers can make quick decisions and improve investors' access to the latest company information.

As illustrated in FIG. 1, a blockchain-based accounting processing system according to an embodiment of the present invention is configured to include a plurality of nodes, and a node is a unit constituting a blockchain network, and distributed nodes As they communicate with each other, they process and store consistent data by the blockchain's own consensus algorithm.

Each node can operate as an independent system on its own, and as the number of nodes increases, the reliability and availability of the entire system increases.

In the node, the trading partner company becomes the first node, the trading partner companies that deal with the trading party become sub nodes, and there is a node, an accounting firm that verifies the trading party and the trading partners.

Since the trading partners and other non-corresponding corporate nodes are not related to each other, it is impossible to access the blockchain-based accounting processing system, that is, only the nodes of the parties in which mutual transactions are conducted share data, and the remaining nodes are related. It can be set to not see missing information.

Node is composed of Blockchain platform, Business Logic, API, Web View Logic, Blockchain Monitor and Web Service Provider.

The Blockchain platform is responsible for implementing and managing algorithms of the blockchain system.It supports distributed networks using p2p communication, maintains data consistency through its own consensus algorithm, and implements blockchain data processing functions.

Business Logic defines the form and processing method of data that needs to be processed on the Blockchain platform, and API provides a predefined type of interface to provide a secure, scalable, and easy to manage approach between the system and business logic. .

Web View Logic implements an interface through the web so that users and business logic can exchange data in a convenient way, and Blockchain Monitor provides a method to check and manage the state of the blockchain system.

The Web Service Provider provides a Web-based data service that can utilize the system regardless of the user's device and operating system, and Users refers to the end-user using the system.

The user may be the purchaser's terminal, the seller's terminal, and the authenticator's terminal.

The blockchain-based accounting processing system provides users with a web-based access method, accesses the blockchain-based accounting processing system using a web browser displayed on the user terminal, and the blockchain-based accounting processing system provides Use the service.

In addition, the authenticator terminal is provided with a buyer's designated authenticator terminal and a seller's designated authenticator terminal, which are provided in a previously registered form.

The authenticator terminal may be an accountant terminal in charge of accounting processing, and is in charge of processing accounting operations that occur during a transaction.

Each personal information (ID, e-mail, retained capital, held assets, etc.) of the purchaser, the seller, the purchaser's authenticator, and the seller's authenticator is registered and provided in the system in advance.

One transaction consists of 6 steps, and each step is also referred to as a transaction.

As shown in Fig. 2, the steps of the transaction consist of contract-order-dispatch-receipt-payment-accounting processing (book record).

Enter the contents of the transaction at the beginning, and then, as the transaction progresses, necessary documents (contract, order, order, receipt, etc.) are automatically generated by inputting only required contents based on the initial input.

The automatically generated document is attached to the system in PDF format, and can later be viewed and downloaded by user selection.

The operation of the user accessing the blockchain-based accounting processing system to input and confirm information is performed using the user's web browser.

All the contents input and attached by the user are stored in the blockchain of the blockchain-based accounting processing system, and the authorized person can check the contents, and the electronic document attached at each step is fixed in PDF format.

In the contract process, the seller accesses the blockchain-based accounting processing system through the seller terminal and inputs the contents of the contract (buyer information, seller information, blockchain-based accounting processing system information, price, quantity, payment conditions, etc.).

The buyer makes an electronic document and attaches the contents of the contract through the buyer terminal.

When the buyer confirms that the transaction has started by entering the contract registration completion, the corresponding content is displayed on the screen of the buyer terminal and the seller terminal, and you can select and confirm the details.

Subsequently, the seller confirms the contents of the contract displayed on the screen and the contents of the attached electronic document, and if there is no problem, enters confirmation to inform that the review has been completed.

If the seller determines that there is a problem with the contents of the contract and the attached document, a modification request can be sent to the buyer, in which case the seller revises the contents and starts the stage of the contract from the beginning.

Subsequently, if the seller informs that the review has been completed by entering the confirmation, the contract step is completed by agreement between the buyer and the seller, and then the process proceeds to the next step, and the contents of the contract and the attached document cannot be changed.

On the other hand, if the seller and the buyer fail to reach an agreement due to disagreement about the contents of the contract, the seller selects the rejection to end the transaction, and when selecting the rejection, the reason for the rejection must be entered, and the transaction is completely Ended and no further steps can be taken.

In the ordering process, the buyer executes an ordering step based on the contents of the contract.

In the order phase, only the essential items necessary for the production of the order form are selectively input and the system automatically creates an order form in PDF format and stores it as an attachment in the blockchain-based accounting processing system.

Subsequently, when the buyer enters the order completion, the content is displayed on the buyer's and seller's screens and can be checked by selecting the details, and the seller selects the order displayed on the screen to check the contents of the attached electronic document, the problem If it does not exist, enter a confirmation to notify you that the review has been completed.

When the seller enters the confirmation and informs them that the review has been completed, the order step is completed by agreement between the buyer and the seller, so the process proceeds to the next step, and the status of the order and the attached document cannot be changed due to complete confirmation.

If the buyer does not want a transaction at the time of the order, he or she can choose to reject the transaction.

On the other hand, if the seller determines that there is a problem with the contents of the order, he or she selects the rejection to end the transaction, and when selecting the rejection, the reason for the rejection must be entered, and the transaction is completely closed and no further steps Cannot proceed.

In the sending process, the seller sends the goods and executes the sending step. At this time, documents required for sending the goods are made in the form of an electronic document in a blockchain-based accounting processing system.

There is no separate input for the shipping step, and an electronic document type shipping document is attached.

Subsequently, only essential items necessary for the production of the shipping documents are selectively input, and the PDF-based shipping documents are automatically created in the blockchain-based accounting processing system and stored as attachments in the blockchain-based accounting processing system.

Subsequently, when the seller inputs the completion of the shipment, the corresponding content is displayed on the terminal screen of the buyer and the seller and can be confirmed by selecting the details

The shipping stage was completed by entering and selecting the seller's data, so the status of the shipment and the attached document cannot be changed after being transferred to the next stage.

On the other hand, if the seller does not want a transaction at the time of shipment, he or she may choose to reject the transaction.

In the receipt phase, the buyer receives the goods and executes the receipt phase.Only the essential items necessary for the production of the receipt documents in the receipt phase are selectively input, and the system automatically fills out the PDF-type receipt documents and processes blockchain-based accounting Save it as an attachment in the system.

Subsequently, when the purchaser inputs the completion of the receipt, the corresponding content is displayed on the terminal screen of the purchaser, the seller, and the authenticator and can be confirmed by selecting the details.

Since the receiving phase was completed by the buyer's input and selection of the data, the status of the receipt and the attached document cannot be changed after being transferred to the next phase.

When the receipt process is completed, a document is automatically created, and it is called a receipt document to distinguish it from the document created after payment.

In the case of a purchaser, the transaction amount is entered as a product of credit and a credit purchase liability in the credit for the buyer, and a transaction amount is input as a credit sales receivable in the credit and the amount of sales in the credit for the seller.

The generated receipt slip can be checked on the buyer and seller screens.

When the receipt slip is generated, the transaction is displayed on the authenticator screen of the buyer and the authenticator screen of the seller, and the authenticator can confirm that the receipt slip has been created and proceed with the verification process.

Whether the authenticator has confirmed the receipt slip does not affect the next step, payment, but whether the receipt slip is confirmed is used as a prerequisite for completing the final stage of accounting.

On the other hand, if the buyer no longer wants to trade due to reasons such as a defect in the goods upon receipt, the transaction can be terminated by selecting reject, and additional work such as the return process and method is a block according to the present invention. It is excluded because it does not meet the purpose of the chain-based accounting processing system.

In the payment process, the buyer checks the contents of the received goods, performs a transfer to the seller, and then executes the payment step.

In the payment phase, the contents of the total payment amount are input, and the electronic document type deposit document such as a deposit slip is automatically created by the blockchain-based accounting processing system and the PDF-type document is attached to the blockchain-based accounting processing system.

In the stage completed until receipt, the buyer is obliged to pay, so the payment stage cannot be rejected.

When the buyer confirms the payment and enters payment completion, the content is displayed on the screen of the buyer, seller, and authenticator, and can be confirmed by selecting details.

The seller selects the payment displayed on the screen to confirm the contents of the attached electronic document, and if there is no problem, informs the user that the review has been completed by entering the confirmation.

When the seller enters the confirmation and informs them that the review has been completed, the payment phase is completed by agreement between the buyer and the seller, so the process proceeds to the next phase. Now, the status of the payment and the attached document are completely confirmed and cannot be changed.

On the other hand, if the seller determines that there is a problem with the contents of the payment, he/she selects the rejection to end the transaction, and when selecting the rejection, the reason for the rejection must be entered, and the transaction is completely closed and no further steps Cannot proceed.

When the payment process is completed, a voucher is automatically generated, and it is called a payment voucher to distinguish it from the voucher generated after receipt.

In the payment slip, the amount of the transaction is entered into the debit for the buyer, the amount of the transaction is entered into the credit, and the amount of the transaction is entered into the debit for the seller.

The generated payment slip can be checked on the buyer and seller screens.

When the payment slip is created, the voucher generated in the transaction is displayed on the purchaser's authenticator and seller's authenticator screens, and the authenticator can confirm that the payment slip has been created and proceed with the verification process.

When the payment step is completed, the purchaser's authenticator and seller's authenticator screens indicate that an accounting audit process is in progress, and the purchaser's authenticator and seller's authenticator performs the verification process on the receipt and purchase documents indicated in the transaction item. By doing this, an audit is performed.

The purchaser's authenticator and the seller's authenticator check the contents of the receipt and purchase slips, and when the confirmation of each document is completed, the audit of the customer is changed to the completed status.

The purchaser's authenticator and the seller's authenticator both have to complete the auditing phase, the transaction is changed to the closed state, and now all stages of the transaction have been completed, and the details of the transaction are recorded in the blockchain-based accounting processing system. It cannot be changed.

As described above, the blockchain-based accounting processing system provides users with an access method through the web, and the screens of web browsers viewed by buyers, sellers, and authenticators are screens such as colors that can be distinguished according to each user's function. Provide configuration.
