Embodiment

[0057] This example captures 50 pieces of financial statement data from 5 listed companies such as Kweichow Moutai and Gree Real Estate in 2018 from the Oriental Fortune Network, and then simulates 30 pieces of original vouchers such as transfer checks, loan slips, special value-added tax invoices, and 20 pieces of bookkeeping The relevant information of the voucher is entered in the blockchain platform in turn, and the model is verified through MPT tree data query and block information tracing. The specific process is as follows:

[0058] a) Open the blockchain platform, the system automatically runs the POW consensus mechanism, that is, mining, to generate the genesis block of the blockchain, such as Figure 9 shown. At the same time, 6 nodes are successfully connected to form a distributed network, such as Figure 10 shown.

[0059] b) Enter all financial information into the system in sequence, the input interface is as follows Figure 11 shown. The system generates co...

Abstract

The invention discloses a financial record information precision trusted storage method based on a block chain. Multi-level multi-granularity decomposition is carried out on financial record information through a rough set theory based on a set theory method, and precise multi-level multi-granularity trusted storage of the financial record information is achieved through an MPT tree of a block chain and a corresponding hash value technology. Based on the rough set theory and technology, different granularities of financial information are considered, and multi-granularity storage of financialrecord information is achieved; based on a block chain MPT tree technology, hierarchical trusted storage of financial record information among different granularities is realized; leaf node trusted storage and branch node trusted storage of the block chain MPT are both considered, and multi-level and multi-granularity financial record information accurate storage is achieved; the structural hash value and the content hash value of the block chain are considered, and multi-level and multi-granularity financial record information trusted storage is achieved.

Description

technical field [0001] The invention relates to the field of financial data management, in particular to a blockchain-based accurate and trusted storage method for financial record information. Background technique [0002] How to strengthen the security and reliability of financial record information in accounting vouchers and financial statements and other materials, make the source of financial information traceable, accountability accountable, and achieve more precise positioning and storage of hierarchical financial record information, is an urgent need to solve problem. [0003] Blockchain is a distributed storage architecture that combines point-to-point transmission, consensus mechanism, hash algorithm and other technologies. It has the characteristics of decentralization, anonymity, immutability, and traceability. Some scholars have studied the application of blockchain trusted storage in financial information management. Tapscott (2016) believes that blockchain's...
