Research On The Fusion Of Blockchain And Enterprise Financial Information Management

In the financial field,with the rapid increase in the amount and dimension of financial information big data,corporate financial information fraud began to appear continuously,and the source of corporate financial information could not be traced in time and related personnel could be held accountable.In addition,many companies have irregularities in their financial statements and lack of key data,which prevents staff from accurately querying the required financial statement data.These problems not only increase the difficulty of corporate financial information management,destroy the interests of relevant stakeholders,but also endanger the ecology of the entire industry.In recent years,with the rise of digital currencies such as Bitcoin,blockchain has received more and more attention.At present,there have been many applications and explorations of blockchain in the field of payment and finance.Blockchain has the characteristics of decentralization,anonymity,trustworthiness,information can not be forged and tampered with,these characteristics are naturally associated with the safety and reliability of information storage,low cost and high efficiency of information transmission and information traceability required by enterprise financial information management Therefore,the blockchain provides new ideas for solving problems in the management of corporate financial information.In this regard,this paper first puts forward the problems that companies have in financial information management: high transmission cost and low efficiency of financial information,irregular and missing financial statement data,and fraudulent and untraceable financial information,and then analyzes these problems with blockchain and The current situation and shortcomings of the integration of enterprise financial information management,on this basis,put forward the demand for the integration of blockchain and enterprise financial information management.Aiming at the needs of the internal mechanism of the 51% double spend attack in the blockchain financial ledger,construct an evolutionary game model,reveal the dynamic evolution of the node strategy and predict the probability of the 51% double spend attack,and then verify the effectiveness of the model through matlab simulation.At the same time,the corresponding risk prevention and control strategies and suggestions are proposed;for the accurate storage of corporate financial statement data based on the MPT tree,the report data is analyzed by rough sets to build a multi-layer granular structure model,which is implemented based on the improved MPT tree Accurate storage of report data and integration of multi-source information;in response to the need to establish a trusted traceability system for corporate financial information based on blockchain,a traceability model for corporate financial information was designed based on timestamps and block hashes,respectively.Demands of departments,blockchain and traceability functions are connected in a system to trace different types of financial information and processes of financial matters;then to address the need to select a consensus mechanism for corporate financial information management and make improvements,choosing to use DPOS consensus The mechanism is used in enterprise financial information management,and based on the Bayesian voting algorithm and the calculation of voting weights to make related improvements;finally for the need to improve the enterprise financial information management blockchain architecture,the application layer,network layer and data layer All elements are combined to form a complete enterprise financial information management blockchain architecture,and an actual blockchain system is built,and the effectiveness of the blockchain model is verified through experiments by grabbing and simulating relevant data.
