[0002] In recent years, blockchain technology has developed rapidly in many fields such as finance, supply chain, and art transactions, and has gradually become one of the infrastructures of the digital economy. Especially in the field of cultural asset transaction management, blockchain, with its transparency, decentralization, and immutability, provides innovative solutions for the confirmation, evaluation, division, and transaction of cultural assets. The blockchain-based cultural asset transaction management method aims to use blockchain technology to digitize and tokenize traditional cultural assets, realize the confirmation and division of assets, and thus improve the liquidity and transaction efficiency of cultural assets.

[0003] At present, there are many deficiencies in the traditional cultural asset transaction and financing process, especially in the evaluation, confirmation of ownership and circulation of cultural assets. Cultural assets usually require multi-party certification, and due to their uniqueness and intangibility, it is difficult to standardize the evaluation. This leads to a complex, time-consuming and low-transparency transaction process for assets. At the same time, the liquidity of cultural assets is poor, and holders often find it difficult to obtain financing by partially selling or pledging cultural assets. Existing traditional platforms usually rely on centralized institutions, lack an effective dynamic pricing mechanism, and are easily affected by human manipulation or market information asymmetry.

It has the following beneficial effects: (1) This method enables cultural asset holders to upload proof documents of cultural assets to the blockchain. The system will assign a unique identifier AID to each asset to ensure that asset ownership and transaction records are transparent and cannot be tampered with. At the same time, through the API interface, multiple data sources such as cultural asset trading platforms and market risk assessment modules can be accessed to automatically obtain valuation data such as scarcity, cultural influence and market volatility of cultural assets, and the valuation Vapp of cultural assets can be calculated in combination with smart contracts.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Example 1 See also Figure 1 The present invention provides a cultural asset transaction management method based on blockchain. To achieve the above purpose, the present invention is implemented through the following technical solutions: comprising the following steps: S1. Submit cultural asset information to the blockchain system through cultural asset holders, set up an API interface to access the cultural asset trading platform to obtain valuation data, and build an asset valuation formula. Input the valuation data into the asset valuation formula to calculate and output the cultural asset valuation Vapp; S2. After the revaluation is completed, the cultural assets are divided into several tokens through the blockchain smart contract, and the value of each token is dynamically adjusted and calculated according to market fluctuations to obtain the initial value of each token Ptoken i ; S3. Put all the initial value Ptoken i Pledge to the blockchain system, then lock the pledged tokens, and calculate the financing amount Rloan through the financing amount and margin requirement formula, and set margin requirements based on market analysis and asset fluctuations; S4. After the pledge is successful, the financing amount Rloan is automatically issued through the blockchain smart contract. The smart contract sets the initial interest rate based on the Token market price and the financing amount, and calculates and outputs the dynamic interest rate Rdynamic based on the dynamic interest rate calculation formula; S5.

If not triggered, execute the margin call calculation formula and output the margin call value Mreq; S6. Construct a comprehensive repayment calculation formula to calculate the total amount of repayment financing Rtotal, and compare and evaluate it with the repayment amount Rrepay, and generate an automatic unlocking mechanism and liquidation mechanism for the pledged Token based on the evaluation results.

[0021] In this embodiment, through the above six steps of the blockchain cultural asset transaction management method, the method realizes the automation of the entire process of cultural assets from title confirmation, valuation to division, pledge and liquidation. First, the method obtains real-time valuation data through the information submitted by the cultural asset holder and accesses the API interface, and outputs the valuation Vapp of the cultural assets in combination with the constructed asset valuation formula. This real-time access to market data greatly improves the accuracy and transparency of the valuation, ensuring that the market value of the asset can accurately reflect the scarcity and influence of the cultural assets. At the same time, through the use of the API interface, the method can dynamically adjust the market risk and asset volatility parameters, making the valuation more real-time and market-adaptive. After the valuation of cultural assets is completed, the method divides the assets into multiple Tokens through a blockchain smart contract, and adjusts the value of each Token Ptoken according to market fluctuations. i . This operation improves the liquidity of assets and allows holders to flexibly pledge tokens for financing. After the pledge is completed, the smart contract automatically calculates the financing amount Rloan based on the financing amount and margin requirement formula, and sets reasonable margin requirements based on market analysis and asset volatility. This process simplifies cumbersome operations and ensures the security and transparency of pledge and financing through the tamper-proof characteristics of blockchain. During the process of pledging tokens, the method monitors the market price in real time through the oracle and sets the liquidation threshold Pmin and margin call mechanism. The smart contract automatically evaluates the market price of the pledged tokens, triggers liquidation or margin call operations, and ensures that the interests of financiers and investors are protected. During the financing period, the method will also dynamically adjust the financing interest rate Rdynamic to match it with market volatility. After the repayment period ends, the smart contract compares the repayment amount Rrepay with the total financing amount Rtotal to generate an automatic unlocking or liquidation mechanism. The overall process not only improves the operating efficiency of the method and reduces human intervention, but also makes the financing process more flexible and transparent through automated management, effectively reduces market risks, and optimizes the management of cultural asset transactions and financing.

[0022] Example 2 This embodiment is explained in Example 1, please refer to Figure 1 , specifically: S1 includes S11 and S12; S11. Upload the certification documents of cultural assets to the blockchain system and store them in the distributed ledger through the blockchain. At the same time, the blockchain system automatically assigns a unique identifier AId to each cultural asset. Then, integrate the blockchain system with the scarcity analysis model, NLP technology and cultural asset trading platform through the API application program interface. When the cultural assets are input into the blockchain system, the valuation data is automatically output. Valuation data includes scarcity parameters of cultural assets , cultural influence coefficient , market trend adjustment coefficient Tz, market trading volume Tvol, market risk coefficient Fx, asset volatility coefficient Zb, overall market volatility Bd and benchmark valuation Jz; Scarcity Parameters Calculated through scarcity analysis model; Cultural influence coefficient The results are obtained by analyzing cultural influence data such as news reports, documents, exhibitions and reviews, combined with NLP technology; The market trend adjustment coefficient Tz is linked to the cultural asset trading market platform through the API interface to extract similar cultural assets in the cultural asset trading market platform for trend analysis; The market transaction volume Tvol is linked to the cultural asset trading market platform through the API interface and obtained by analyzing historical transaction records and auction house data; The market risk coefficient Fx is linked to the cultural asset trading market platform through the API interface and accessed to the risk assessment module of the cultural asset trading market platform for extraction; The asset volatility coefficient Zb is obtained by linking the cultural asset trading market platform through the API interface and combining macroeconomic data and market volatility for comprehensive analysis; The overall market volatility Bd is linked to the cultural asset trading market platform through the API interface and is obtained based on the volatility analysis of the overall data of the cultural asset trading market platform; The benchmark valuation Jz is obtained by averaging the trading history of similar assets; S12, constructing an asset valuation formula, inputting the acquired valuation data into the asset valuation formula, and calculating and outputting the cultural asset valuation Vapp; The cultural asset valuation Vapp is calculated using the following asset valuation formula; .

[0023] In this embodiment, the proof documents of cultural assets are uploaded through the blockchain method and a unique identifier AID is assigned to them. The ownership and information of cultural assets are permanently recorded in the distributed ledger of the blockchain to ensure the transparency and immutability of the data. Compared with traditional paper documents or centralized digital methods, the decentralized nature of blockchain makes the cultural asset confirmation process more transparent and secure, while reducing the possibility of information distortion or tampering. Through this improvement, the owners of cultural assets can gain higher trust, and the circulation of assets becomes more convenient and safer. Through multi-dimensional data analysis, including market trends, trading volume, and risk factors, a more accurate and comprehensive valuation model is constructed. This method not only improves the accuracy of valuation, but also dynamically reflects market changes, ensuring that the valuation of cultural assets is always consistent with the actual market situation. By constructing a complex asset valuation formula and automatically outputting the valuation Vapp of cultural assets. Compared with traditional valuation methods, this automated valuation process not only eliminates the complexity of manual calculations, but also greatly improves the efficiency and accuracy of decision-making. This method can automatically and real-time process large amounts of data, quickly derive accurate valuation results, reduce the cost and potential errors of manual intervention, and improve the speed and efficiency of asset trading and financing decisions.

[0024] Example 3 This embodiment is explained in Example 2. Please refer to Figure 1 , specifically: S2 includes S21 and S22; S21. Use the blockchain’s smart contract programming language Solidity to write smart contracts and define the division rules of cultural assets, dividing cultural assets into several tokens, each of which represents part of the value and ownership of the cultural assets; S22. After tokenization, use oracle technology to monitor the cultural asset trading market in real time, analyze and obtain the market volatility adjustment coefficient Tzs, and then calculate the initial value Ptoken of each token based on the cultural asset valuation Vapp and the preset total number of tokens Ttotal. i ; The initial value of each Token is Ptoken i Obtained through the following algorithm formula; ; Where Ptoken i Indicates the initial value of the i-th token.

[0025] In this embodiment, the method uses blockchain technology to achieve the tokenization of cultural assets and real-time monitoring of market value, which brings many significant beneficial effects. Through the writing of smart contracts, cultural assets are divided into several tokens, so that each token represents part of the value and ownership of the asset. Compared with the traditional overall asset trading method, tokenization allows holders to flexibly trade or pledge part of the assets, which improves the liquidity of assets, while lowering the investment threshold and facilitating more investors to participate. This improvement in asset segmentation and ownership management simplifies the transaction process of cultural assets and enhances the market's acceptance of cultural assets. Using oracle technology for real-time market evaluation, the initial value of each token Ptoken i It can be adjusted dynamically according to market fluctuations. By combining the market volatility adjustment coefficient Tzs and the cultural asset valuation Vapp, the system can accurately calculate the initial value of each Token and keep it consistent with the market supply and demand dynamics. Compared with the traditional fixed price mechanism, this real-time adjustment mechanism is more flexible and effective, can respond quickly to market changes, and reduce price deviations and risks caused by market fluctuations.

[0026] Example 4 This embodiment is explained in Example 3, please refer to Figure 1 , specifically: S3 includes S31 and S32; S31. The holder pledges the divided tokens to the blockchain system. The blockchain system uses the smart contract programming language Solidity to design the pledge process. The pledge process includes the locking of tokens, calculation of the financing amount and unlocking conditions. The pledged tokens and pledge status are recorded in the decentralized ledger of the blockchain. S32. Through big data analysis and the cultural asset trading market platform, the market volatility Brisk of cultural assets is predicted and calculated, and dynamically updated based on historical price fluctuations and changes in supply and demand in the current cultural asset trading market. According to the number of pledged tokens and the market value of each token, the formula for financing amount and margin requirement is constructed to calculate the output financing amount Rloan; The financing amount Rloan is calculated by the following formula of financing amount and margin requirement; ; In the formula, Npledged represents the number of pledged tokens, which represents the total amount of tokens pledged by the holder, and Bl represents the margin ratio, which prevents market fluctuations from causing the pledged assets to be insufficient to repay the financing amount. It is usually set based on market risks and asset fluctuations. The higher the margin ratio, the lower the financing risk.

[0027] In this embodiment, the method realizes the Token pledge and financing calculation of cultural assets through blockchain technology, which brings many beneficial effects. First, the holder can pledge the split Token to the blockchain method, and the smart contract automatically manages the pledge process, including the locking of the Token, the calculation of the financing amount, and the setting of the unlocking conditions. All pledge information and status are recorded in the decentralized ledger of the blockchain, ensuring the transparency and immutability of the pledge process. Compared with the traditional centralized financing platform, this decentralized pledge process reduces the intermediary links, improves the security and trust of the transaction, and ensures the safe management of the pledged assets. Then, through big data analysis and the cultural asset trading market platform, the market volatility Brisk of cultural assets is predicted and dynamically updated, and the financing amount Rloan and margin requirement formula are constructed in combination with the market value and quantity of the Token, and the financing amount Rloan and margin requirement formula are automatically calculated to automatically calculate the financing amount that the holder can obtain. This method combines real-time market data and historical price fluctuations, so that the financing amount and margin ratio can more accurately reflect the current market conditions, effectively reducing the risks caused by market fluctuations and improving the flexibility and efficiency of financing.

[0028] Example 5 This embodiment is explained in Example 1, please refer to Figure 1 , specifically: S4 includes S41; S41. After the Token is pledged successfully, the financing amount Rloan is issued through the blockchain smart contract. At the same time, the smart contract sets the initial interest rate based on the market price of the Token and the financing amount. During the financing period, by constructing a dynamic interest rate calculation formula, the smart contract dynamically adjusts the interest rate according to market fluctuations and outputs the dynamic interest rate Rdynamic. The dynamic interest rate Rdynamic is calculated by the following dynamic interest rate calculation formula; ; In the formula, Rbase represents the initial annualized interest rate, Represents the interest rate adjustment factor, which is used to control the fluctuation range of interest rates.

[0029] In this embodiment, the method automatically issues the financing amount Rloan through a smart contract after the Token is successfully pledged, eliminating the time delay of manual approval and processing in traditional financing, making the financing process more efficient. The method sets the initial interest rate Rbase according to the market price of the Token and the financing amount, and dynamically adjusts the interest rate Rdynamic through a smart contract, automatically updating the interest rate according to market fluctuations. Compared with the traditional fixed interest rate model, this dynamic interest rate mechanism can be flexibly adjusted according to market changes, ensuring that the financing interest rate is more reasonable and matches market conditions, reducing the interest rate risk of the financier, and providing a risk compensation mechanism for investors.

[0030] Example 6 This embodiment is explained in Example 5. Please refer to Figure 1 , specifically: S5 includes S51, S52 and S53; S51. Use the oracle to obtain the real-time Token price from the external market, and transmit the real-time Token price obtained from the external market to the blockchain smart contract through the API interface, set the liquidation threshold Pmin, and set the liquidation trigger condition according to the liquidation threshold Pmin. The specific settings are as follows; When the initial value of the i-th Token is Ptoken i When the value is ≥ the liquidation threshold Pmin, it means that the token value has not fallen below the token value in the cultural asset trading market, and the margin call strategy will be implemented at this time; When the initial value of the i-th Token is Ptoken i When the value of the token falls below the liquidation threshold Pmin, it means that the token falls below the value of the token in the cultural asset trading market. At this time, a liquidation reminder is sent to the blockchain system, prompting the token holder to liquidate and redeem within 7 working days. After 7 working days, the forced liquidation operation will be automatically executed; When the initial value of the i-th Token is Ptoken i ×20%<liquidation threshold Pmin, it means that the Token falls below 20% of the market Token value. At this time, the smart contract will immediately initiate a forced liquidation operation and automatically sell the pledged Token to repay the financing amount Rloan.

[0031] S52. When the token value does not fall below the token value in the cultural asset trading market, the smart contract automatically executes the trigger mechanism and margin calculation and additional notification, and outputs the additional margin value Mreq; The trigger mechanism is ,in, Represents a positive number, Indicates the margin call threshold, "on" means margin call, and "off" means no margin call; S53, when the trigger mechanism is on, the margin call calculation formula is triggered to execute, and the margin call value Mreq is output; The margin call value Mreq is calculated using the following margin calculation formula: ; In the formula, Indicates the liquidation ratio, which is used to calculate the number of tokens that need to be added to ensure that the pledged assets can cover the financing amount.

[0032] In this embodiment, the method obtains real-time Token prices from the external market through an oracle, and transmits these data to the blockchain smart contract, automatically sets the liquidation threshold Pmin, and dynamically determines whether to trigger the liquidation or margin call mechanism based on market price changes. This real-time monitoring method ensures that the Token value can accurately reflect market fluctuations, allowing the method to timely evaluate and respond to market risks, which is faster and more efficient than traditional manual risk monitoring methods. When the Token value approaches or falls below the liquidation threshold Pmin, the method automatically issues a warning to the holder and performs risk management through forced liquidation or margin call mechanisms. The margin call calculation and notification function is then automatically triggered through the smart contract. When market conditions do not meet the liquidation requirements, the holder can avoid the liquidation of assets by adding margin Mreq. This automated margin call mechanism enables holders to take measures before market fluctuations, reduces liquidation risks, and provides holders with the opportunity to flexibly respond to market fluctuations.

[0033] Example 7 This embodiment is explained in Example 6. Please refer to Figure 1 , specifically: S6 includes S61 and S62; S61. After the refinancing period ends, the total repayment amount calculation formula is executed to output the total repayment amount Rtotal; The total amount of financing repayment Rtotal is obtained by the following total repayment calculation formula; ; Where Tterm represents the financing term.

[0034] S62. Compare and evaluate the total amount of financing to be repaid Rtotal and the repayment amount Rrepay, and generate a pledge Token unlocking mechanism. The specific evaluation contents are as follows; When the total amount of financing repaid Rtotal ≤ the repayment amount Rrepay, it means that the pledged amount of the Token has been repaid. At this time, the pledged Token is automatically unlocked through the smart contract; When the total repayment financing amount Rtotal> the repayment amount Rrepay, it means that the pledged amount of the Token has not been repaid. At this time, the pledged Token will not be unlocked and a prompt will be displayed that it has not been repaid.

[0035] In this embodiment, the method automatically calculates the total amount Rtotal that the financier needs to repay through the total repayment calculation formula, and dynamically adjusts it according to the financing term Tterm. This automated calculation method ensures the accuracy of the repayment amount, avoids errors in manual calculations, and improves the transparency and efficiency of the repayment process. Compared with the traditional repayment calculation method, the method can automatically generate a clear repayment plan based on the length of the financing period and the relevant interest rate, reducing the workload of the financier and the method. By comparing the actual repayment amount Rrepay of the financier and the amount to be repaid Rtotal, it is determined whether to unlock the pledged Token.
