Description

System solution method for enterprise financial supervision and audit based on block chain supply chain

Technical Field

The invention belongs to the field of block chains, and relates to a block chain supply chain-based enterprise financial supervision and audit system solution.

Background

One difficulty of the current financial audit is difficult evidence obtaining and tracing, a lot of information cannot be traced back after being tampered, the block chain technology can guarantee the integrity, the permanence and the non-tampering of all data, therefore, the difficult and pain points of the audit industry in the aspects of easy evidence obtaining, tracing, association, tracing and the like can be effectively solved, the block chain can automatically process abnormal records through information such as whether each node verifies and approves the block and transaction information in the block, whether a network node is attacked, whether an account book of each node is complete and the like, and real-time audit becomes possible. Although block chains can have the above advantages, there is currently no good solution for on-chain data penetration policing.

and (3): the program traverses all the block information, the supervisory organization selects which blocks to audit, inputs the starting number and the ending number of the blocks to be audited, then obtains the transaction hash address on each block and stores the transaction hash address into a text, the transaction hash address is an index of each transaction on a block chain, and the supervisory organization can find corresponding contents such as detailed fund information and the like through the index;

and (4): the abi file of the contract is uploaded to the server locally, the abi file can be acquired from the intelligent contract which is already deployed by an enterprise, and the contract is sent to the server to inform a background supervision agency of the contract to be audited;

and (5): the server decodes the transaction content on the block according to the transaction hash address by using abi file content obtained from the client and a private key local to the enterprise, and then stores the decoded data in a database and presents the data in a relational data structure mode;

and (6): and the monitoring organization can perform proofreading and auditing on the financial data in the relational database according to different monitoring requirements.

Preferably, this document describes the mode of operation by a simple front-end system operation.

(III) advantageous effects

Compared with the prior art, the invention provides a systematic solution method for enterprise financial supervision and audit of a block chain supply chain, which has the following beneficial effects:

the invention can conveniently export large-scale data on an enterprise financial chain, recovers abstract encrypted data into professional financial data through visual operation, prevents enterprises from tampering data, facilitates audit of a supervision organization, and improves supervision efficiency.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-10, the present invention provides a system solution for enterprise financial monitoring audit of a block chain supply chain: comprises the following steps of (1): configuring bottom chain related environment variables; step (2): acquiring current block information and block height; and (3): the program traverses all block information, and the management mechanism selects which blocks are to be audited, acquires the transaction hash address on each block and stores the transaction hash address in a text; and (4): uploading abi files of the contract locally to the server; and (5): the server uses abi file content obtained from the client and a private key local to the enterprise to decode the transaction content on the tile according to the transaction hash address; and (6): and the monitoring institution checks and audits the financial data. Through the steps, the encrypted abstract data on the block removing chain can be converted into the relational visual data while the traceable data special effect of the block removing chain is fully utilized, the problem of possible modification of an enterprise account book is solved, enterprise supervision is enhanced, the encrypted abstract data on the block removing chain can be converted into the relational visual data, and penetrating supervision is achieved.

In a specific implementation process, the step (1) of the invention: as shown in fig. 1, the environment variables related to the bottom chain are configured, where, taking local ip addresses as an example, port numbers are addresses for communication between the backend service and the block chain, and the ip addresses and the port numbers need to be filled in before the test is performed;

in the specific implementation process, the step (2): according to the content of fig. 2, we can obtain the current tile information and tile height in this step, the system will automatically obtain this tile information and tile height from the backend server, the returned tile information is presented in the form of hash value, and the returned tile height indicates how many tiles have been currently generated;

in the specific implementation process, the step (3): and (3) according to the latest block height obtained in the step (2) or the blocks which are audited before, selecting which blocks are audited by the supervision agency, inputting the starting number of the blocks to be audited and the ending number of the blocks as shown in the figure 3, and performing transaction hash reading after confirming the block range. Then, a transaction hash address on each block is obtained and stored in a text, the transaction hash address is an index of each transaction on a block chain, a supervision organization can find corresponding contents such as detailed fund information through the index, and the position of each block and the transaction hash of the corresponding block are recorded in a file with the same format as that of fig. 4;

in the specific implementation process, the step (4): finding abi files with consistent file content formats as shown in fig. 6 to upload to a back-end server as shown in fig. 5, abi file acquisition may be acquired from an intelligent contract already deployed by an enterprise, and sending the contract to a server to inform a background regulatory agency of the contract to be audited;

in the specific implementation process, the step (5): the client selects the storage mode of the decoded data (currently, a database mode is adopted) according to the steps shown in fig. 7, then the server decodes the transaction content on the block according to the transaction hash address by using the abi file content obtained in step (4) and the private key local to the enterprise, and then the server stores the decoded data in the database to present the data in a relational data structure mode. The decoded data through the code segment written in fig. 9 will be stored in the oracle database, and querying the oracle database will have the data records shown in fig. 8;

in the specific implementation process, the step (6): and the monitoring institution checks and audits the financial data.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
