Description

Technical Field

[0001] The present invention relates to the field of blockchain technology, and in particular to a blockchain-based virtual space asset management method, device, equipment and medium. Background Art

[0002] In the traditional real estate information management system, there are significant flaws in the management and circulation of real estate-related data. These flaws have become a major bottleneck restricting the efficient operation of the real estate market and the protection of user rights. Specifically, existing technologies face the following three problems:

[0003] 1. Information fragmentation and lack of transparency

[0004] Core elements of real estate data (such as ownership, transaction history, and maintenance records) are often stored in separate locations across various administrative agencies or departments. For example, property rights information is managed by the housing authority, maintenance records are kept by property management companies, and transaction data may be dispersed across financial institutions or intermediary platforms. This fragmented storage model leads to information silos, forcing users to apply for and consolidate information through multiple institutions one by one, a cumbersome and time-consuming process. Furthermore, the lack of a unified information disclosure mechanism makes it difficult for users to fully understand the true status of a property. This lack of transparency directly exacerbates information asymmetry in the market. Without complete data support, homebuyers often face the risk of insufficient basis for decision-making, which in turn impacts the fairness of transactions.

[0005] 2. Inefficient information acquisition

[0006] Existing technologies require users to rely on traditional offline application processes to obtain historical property information, requiring them to submit written documents, make multiple trips to different agencies, and even pay additional fees to retrieve the files. This process is not only inefficient but also hindered by data barriers and confidentiality policies between agencies, making it difficult for ordinary users to easily access complete property records. This high barrier to entry further exacerbates the information disadvantages of market participants, particularly individual homebuyers, who are vulnerable to additional risks due to missing information, such as purchasing properties with ownership disputes or hidden quality issues, ultimately undermining market trust.

[0007] 3. Lack of data security and credibility

[0008] Traditional real estate information management systems often use centralized databases to store data and rely on manual review mechanisms for information updates and verification. However, these systems lack effective technical means to prevent data tampering. For example, maintenance records can be arbitrarily modified due to human oversight or profit-driven factors, and key information such as transaction prices can be falsified. Furthermore, centralized storage models present a single point of failure risk. If the database is attacked or damaged, data can be permanently lost. These issues severely undermine the credibility of real estate information, raising user doubts about data authenticity, leading to frequent market disputes and further hindering the healthy development of the real estate industry.

[0009] In summary, traditional real estate information management technologies, due to fragmented information, inefficient access, and insufficient tamper-proofing, are no longer able to meet modern society's demands for data transparency, usability, and security. An innovative technical solution is urgently needed to fundamentally address these issues by systematically optimizing data storage, circulation, and verification mechanisms, thereby driving the evolution of real estate information management towards efficiency, reliability, and user-friendliness.

[0045] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0046] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0047] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the present invention. As used in the specification and appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0048] It should be further understood that the term "and / or" used in the present description and the appended claims refers to and includes any and all possible combinations of one or more of the associated listed items.

[0049] As used in this specification and the appended claims, the term "if" can be interpreted as "when" or "upon" or "in response to determining" or "in response to detecting," depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "upon determination" or "in response to determining" or "upon detection of [described condition or event]" or "in response to detecting [described condition or event]," depending on the context.

[0050] See also Figure 1 , the embodiment of the present invention provides a virtual space asset management method based on blockchain, such as Figure 1 As shown, the method includes the following steps:

[0051] S1, collects property information of a property and stores the property information based on a blockchain, wherein the property information includes apartment type information, property ownership information, transaction information, and maintenance information.

[0052] In a specific implementation, the real estate information can be input by the user or collected from a data source, which is not specifically limited in the present invention. The data source can be a property management system, a government department website, etc., which is not specifically limited in the present invention.

[0053] Furthermore, storing property information on the blockchain ensures that it cannot be tampered with. This property information includes apartment layout information, property ownership information, transaction information, and maintenance information, which are not specifically limited in the present invention. Apartment layout information can specifically be a 3D apartment layout, such as a BIM model of the property; property ownership information can specifically be information on the ownership of the property; transaction information can specifically be information related to the property transaction process; and maintenance information can specifically be information related to the renovation, repair, and maintenance of the property.

[0054] The tamper-proof nature of blockchain ensures the integrity and authenticity of real estate information during storage and transmission, avoiding the risk of data being easily tampered with in traditional systems.

[0055] Blockchains can be public or private. Besides using public chains (such as Ethereum and Bitcoin), you can also choose private or consortium chains. Private chains are controlled by specific organizations or institutions and offer greater privacy and controllability. Consortium chains, on the other hand, are jointly maintained by multiple organizations and offer the openness of public chains with the controllability of private chains.

[0056] Advantages: Private chains and consortium chains can better meet the special needs of specific organizations or industries, such as data privacy protection and compliance requirements.

[0057] Applicable scenarios: Suitable for scenarios with high requirements for data privacy and control, such as within enterprises and government agencies.

[0058] In some preferred embodiments, the above step of "collecting property information of a property" specifically includes the following steps: determining whether a preset data source has updated the property information of the property; if the preset data source has updated the property information of the property, obtaining the updated property information of the property from the data source.

[0059] In a specific implementation, the access address of a data source is pre-set. The data source may be a property management system, a government website, or the like, and the present invention is not particularly limited thereto. The data source is periodically queried to determine whether the property information of a property has been updated. If so, the updated property information is obtained from the data source based on the API interface of the data source.

[0060] In this embodiment, a pre-set data source automatic monitoring and information update mechanism ensures that real estate information stored on the blockchain is always synchronized with the latest data. Traditional systems rely on manual operations to update information, which is prone to delays or omissions. However, this solution automatically determines the update status of the data source, captures the latest information in real time, and stores it on the blockchain, reducing errors caused by human intervention. For example, when a property management company updates a maintenance record, the system immediately captures the change and updates the blockchain data. This not only improves the timeliness of information but also avoids transaction disputes caused by information lags. Furthermore, the automated process reduces system maintenance costs, making large-scale real estate information management more feasible.

[0061] In some preferred embodiments, the above step of "storing the real estate information based on the blockchain" specifically includes the following steps: obtaining verification data of the real estate information, the verification data being used to determine whether the real estate information has been tampered with; establishing a mapping relationship between the real estate information and the verification data of the real estate information; storing the verification data of the real estate information in the blockchain, and storing the real estate information and the mapping relationship in a preset centralized database.

[0062] In a specific implementation, the verification data for the property information can be a hash value of the property information, which is used to determine whether the property information has been tampered with. As can be understood, if the property information has been tampered with, the hash value of the property information will inevitably change. Therefore, the hash value can be used to verify whether the property information has been altered.

[0063] The mapping relationship is used to record the corresponding relationship between the real estate information and the verification data. Based on the mapping relationship, the storage location of the verification data of the real estate information can be determined, thereby facilitating the retrieval of the verification data of the real estate information.

[0064] Storing the verification data of the real estate information in the blockchain can reduce the storage space occupied by the blockchain. The real estate information and the mapping relationship are stored in a preset centralized database. The centralized database has strong reading performance, making it easier to read the real estate information.

[0065] In this embodiment, a hybrid storage architecture combining blockchain and centralized database is employed, separating the storage of property information from verification data. The blockchain only stores verification data (e.g., hash values) to verify the integrity of the property information in the centralized database, while the property information itself is stored in the centralized database to improve read and write efficiency. When a user accesses information, the system quickly locates the verification data in the blockchain through mapping relationships to verify whether the information has been tampered with. This design preserves the blockchain's tamper-proof advantages while avoiding the bottlenecks of blockchain storage capacity and speed, achieving a balance between security and performance. For example, for frequently updated transaction records, the centralized database can quickly respond to queries, while the verification data stored on the blockchain ensures that it cannot be tampered with. This dual guarantee improves the overall efficiency of the system.

[0066] Alternatively, in some other embodiments, only specific types of real estate information are uploaded to the blockchain, such as property rights information, transaction information, etc. The authenticity of other real estate information can be verified based on the property rights information and transaction information, thereby further reducing the occupation of the blockchain.

[0067] S2: If a request for information retrieval of the real estate is received from the terminal, the real estate information of the real estate is obtained based on the blockchain.

[0068] In a specific implementation, if a request for information retrieval of the property is received from a terminal, the property information of the property is obtained based on the blockchain. Obtaining the property information of the property based on the blockchain can effectively prevent the property information from being tampered with.

[0069] In some preferred embodiments, the information retrieval request can be sent to the server by the user by scanning a property's QR code or reading a property's NFC tag. As will be appreciated, each property has a unique QR code or NFC tag. The user can read the property's information by identifying the QR code or NFC tag through a terminal, thereby sending an information retrieval request based on the property's information, greatly improving the user's convenience in obtaining property information.

[0070] Compared with QR code recognition, NFC tags are small in size, low in cost, do not require a camera, and are more convenient to operate.

[0071] The terminal can be a mobile terminal or a web terminal. In addition to accessing information through the mobile app, it can also provide web access. Users can access the website through a browser to view and manage real estate information.

[0072] Advantages: Web access is not restricted by device, and users can access information anywhere with an internet connection. Mobile apps provide a more convenient operation experience.

[0073] Applicable scenarios: Suitable for users who need to access information across platforms, such as real estate agents, investors, etc.

[0074] In some preferred embodiments, the above step of "obtaining the property information of the property based on the blockchain" specifically includes the following steps: obtaining the property information and the mapping relationship of the property from the centralized database, and obtaining the verification data of the property information from the blockchain based on the mapping relationship; verifying the property information using the verification data of the property information; if the property information verification passes, determining that the status of the property information is a trusted state; if the property information verification fails, determining that the status of the property information is an untrusted state.

[0075] In a specific implementation, first, based on the property information index, such as the property ownership certificate number, the property information and mapping relationship of the property are obtained from the centralized database. Furthermore, based on the mapping relationship, the storage location of the verification data of the property information in the blockchain is determined, and the verification data of the property information is further retrieved from the blockchain. After obtaining the verification data, the property information is verified based on the verification data to ensure that the property information has not been tampered with.

[0076] In this embodiment, a dual verification mechanism for verification data further enhances the credibility of information. When retrieving property information, the system not only obtains data from the centralized database but also verifies its consistency against verification data stored on the blockchain. If the verification passes, the information is marked as trusted; otherwise, it is marked as untrustworthy and an alarm is issued. For example, if a maintenance record in the centralized database has been tampered with, its hash value will not match the original verification data stored on the blockchain. The system will automatically identify and exclude this abnormal information. This mechanism effectively prevents data tampering and forgery, ensuring that the information users receive is authentic and reliable. Furthermore, the dynamic verification process requires no additional user intervention, balancing security and ease of use.

[0077] S3, arranging the property information of the property in chronological order, obtaining an information retrieval result, and returning the information retrieval result to the terminal.

[0078] In a specific implementation, the real estate information of the real estate is arranged in chronological order, so that users can clearly understand the transactions, maintenance, changes, etc. of the real estate throughout its life cycle.

[0079] In this embodiment, arranging the real estate information in chronological order can intuitively display the dynamic changes of the real estate throughout its life cycle (such as multiple transaction records and maintenance history), helping users to quickly understand the real estate background.

[0080] In some preferred embodiments, the above step of "arranging the property information of the property in chronological order to obtain the information retrieval result" specifically includes the following steps: filtering out property information with a trusted status from all the property information of the property as target property information; and arranging all the target property information of the property in chronological order to obtain the information retrieval result.

[0081] In a specific implementation, only credible real estate information is screened as target real estate information, and all target real estate information of the real estate is arranged in chronological order to obtain the information retrieval result. This ensures that all real estate information in the information retrieval result is credible, completely avoiding the possibility of users receiving false information.

[0082] In this embodiment, by filtering trusted real estate information and arranging it in chronological order, the accuracy and readability of the information retrieval results are significantly improved. In traditional systems, users may make wrong decisions due to mixed invalid or erroneous information. This solution automatically filters out untrusted data and retains only verified real information, reducing the user's information screening costs. For example, in a real estate transaction scenario, the buyer can directly view complete and trusted records (such as ownership changes and maintenance history) arranged in timeline without worrying about data falsification. This design not only optimizes the user experience, but also enhances market transparency and provides a solid foundation of trust for both parties to the transaction.

[0083] In some preferred embodiments, the information retrieval request includes identity authentication information, and the method further includes: performing identity verification on the information retrieval request based on the identity authentication information, the identity verification including at least one of account and password verification, biometric information verification, and multi-factor authentication verification; if the identity verification of the information retrieval request passes, executing the step of obtaining the real estate information of the real estate based on the blockchain; if the identity verification of the information retrieval request fails, rejecting the information retrieval request.

[0084] In practice, user identity verification is performed before retrieving property information, ensuring the security of access and effectively preventing information leaks. Account and password verification verifies the accuracy of the user's account and password. Biometric verification verifies the accuracy of the user's biometric information, such as face and fingerprint. Multi-factor authentication verification involves verification using SMS verification codes, hardware tokens, and other methods.

[0085] In this embodiment, information access permissions are strictly controlled through a multi-verification verification mechanism (such as passwords and biometrics) to prevent unauthorized access. In traditional systems, the identity authentication method is single (such as password verification only), which is easy to be cracked or misused. However, this solution combines account passwords, biometrics (such as fingerprints and facial recognition) and multi-factor authentication to greatly improve the security of identity authentication. For example, users need to enter their password and confirm it with a mobile phone verification code before they can access sensitive property information. Even if the password is leaked, attackers cannot bypass the biometric link, thereby effectively protecting user privacy. In addition, the combination of identity authentication and blockchain retrieval ensures the traceability of the entire data access process, further strengthening the security of the system.

[0086] In some preferred embodiments, the information retrieval request includes identity verification information, and the method further comprises: if the identity verification of the information retrieval request passes, determining a request level corresponding to the information retrieval request based on the identity verification information. Accordingly, obtaining the property information of the property based on the blockchain includes: determining an information level corresponding to the request level; and obtaining the property information corresponding to the information level based on the blockchain.

[0087] In a specific implementation, different users correspond to different request levels, and different request levels correspond to different information levels. Both the request level and the information level can be set by those skilled in the art and are not specifically limited by the present invention. By returning only property information at the information level corresponding to the request level, it is possible to effectively prevent important property information from being leaked to unrelated personnel, thereby ensuring the accuracy of the property information.

[0088] In this embodiment, differentiated information access control is achieved through a dynamic permission grading mechanism. The system determines the user's request level (e.g., ordinary user, authorized institution) based on the user's identity verification results and only returns real estate information of the corresponding level. For example, ordinary homebuyers can only view public transaction records, while property owners or legal institutions can access detailed maintenance records and property rights change logs. This design not only meets the information needs of different roles but also avoids the risk of sensitive data leakage. At the same time, the combination of permission grading and blockchain retrieval ensures the accuracy and compliance of data output. For example, in a judicial evidence collection scenario, the court can quickly obtain complete and reliable real estate files through high-level permissions, significantly improving judicial efficiency.

[0089] An embodiment of the present invention proposes a blockchain-based virtual space asset management method, comprising: collecting property information of a property and storing the property information on a blockchain. The property information includes unit type information, property ownership information, transaction information, and maintenance information; upon receiving a request from a terminal for information retrieval of the property, retrieving the property information on the blockchain; arranging the property information in chronological order to obtain an information retrieval result, and returning the information retrieval result to the terminal. Using blockchain technology, the unit type, property ownership information, transaction information, and maintenance information of the property are centrally stored and returned to the terminal user after being sorted in chronological order. The tamper-proof nature of blockchain ensures the integrity and authenticity of property information during storage and transmission, eliminating the risk of data tampering in traditional systems. Furthermore, arranging information in chronological order can intuitively display dynamic changes throughout the property's lifecycle (such as multiple transaction records and maintenance history), helping users quickly understand the property's background. Furthermore, the distributed storage mechanism based on blockchain enhances the system's anti-attack capabilities. Even if some nodes fail, data can still be recovered through other nodes, significantly improving system reliability. This solution fundamentally solves the problems of traditional real estate information being scattered, opaque, and unreliable, and provides users with efficient and reliable real estate information retrieval services.

[0090] The introduction of blockchain technology provides a new solution for the confirmation and transaction management of virtual space assets. By combining the underlying characteristics of blockchain with multi-dimensional technical means, this invention significantly optimizes the core issues in traditional real estate information management. The specific technical effects can be systematically explained from the following aspects:

[0091] 1. Comprehensive Improvement of Information Transparency

[0092] The core characteristics of blockchain technology lie in its immutability and distributed ledger mechanism. By writing real estate information (such as ownership, transaction history, and maintenance records) to the blockchain, all data is permanently stored on the chain's nodes in the form of timestamps and hash values. Once recorded, the data cannot be modified or deleted by any single party, thus ensuring the authenticity and integrity of the information. For example, changes in property ownership are recorded on the blockchain in an irreversible chain structure, allowing users to trace back to the initial registration state, completely eliminating the risk of information tampering caused by manual operations or data silos in traditional systems.

[0093] Furthermore, blockchain supports comprehensive disclosure and easy access to information. The system generates a unique identifier (such as a QR code) for each asset, allowing users to access the complete historical data stored on the chain with a simple scan. This transparency not only lowers the barrier to information access for users but also breaks down traditional information barriers between institutions through open data sharing. Homebuyers, financial institutions, and regulators can all make decisions based on the same data source, significantly reducing transaction disputes caused by information asymmetry and fostering a fairer market environment.

[0094] 2. Significant Optimization of Information Acquisition Efficiency

[0095] Traditional real estate information management relies on multi-agency collaboration and offline processes, requiring users to repeatedly submit applications and wait for review, resulting in inefficiency and high costs. This system leverages blockchain technology to centrally store and standardize information management, allowing users to quickly access required data through a unified platform. For example, after scanning a QR code, the system automatically retrieves and integrates a property's full lifecycle information (such as floor plans, transaction timelines, and maintenance records) from blockchain nodes and presents it in a visual interface, eliminating the cumbersome process of cross-departmental inquiries.

[0096] Furthermore, blockchain's distributed architecture ensures the system's high concurrent processing capabilities. Even when massive numbers of users access the system simultaneously, data can be quickly responded to via the nearest node, ensuring service stability and real-time performance. This "one-stop" information acquisition model significantly reduces user operation time and improves the overall service experience, making it particularly suitable for the high-frequency trading real estate market.

[0097] 3. Significant Enhancement of Information Security

[0098] This system utilizes multiple technologies to establish a comprehensive security framework. At the identity verification level, the system integrates multi-factor authentication mechanisms (such as passwords, biometrics, and dynamic tokens) to ensure that only authorized users can access sensitive information. For example, property owners must verify their identity through fingerprint or facial recognition before they can upload maintenance records or initiate transactions, effectively preventing identity theft or unauthorized access.

[0099] At the data storage level, the distributed nature of blockchain further strengthens the system's resilience to attacks. Data is stored in multiple nodes globally, ensuring that a single node failure or malicious attack will not affect the overall system's operation. Even if partial data is corrupted, the remaining nodes can quickly restore a complete copy through consensus. Furthermore, blockchain utilizes asymmetric encryption technology to protect transmitted data, ensuring that information cannot be intercepted or tampered with during transmission. This end-to-end security design significantly reduces the risk of data leakage and forgery, providing technical support for the long-term, reliable storage of real estate information.

[0100] IV. Effective promotion of healthy market development

[0101] Improved information transparency and security have directly promoted the standardized operation of the real estate market. The immutability of blockchain makes fraudulent transactions, forged contracts, and other such activities difficult to carry out. For example, buyers and sellers can verify a property's transaction history and ownership status in real time through on-chain records, preventing intermediaries from concealing information and profiting from it. This transparency mechanism strengthens trust among market participants, reduces disputes caused by information opacity, and thus maintains market fairness.

[0102] Furthermore, the introduction of smart contracts further streamlines the transaction process. Contract rules are pre-encoded in the blockchain, automatically executing property transfers and fund settlements once transaction conditions are met, reducing manual review steps and reliance on intermediaries. For example, once a purchase price is paid, the smart contract immediately triggers a change in ownership and updates the on-chain record, significantly shortening the transaction cycle. This automated model not only improves transaction efficiency but also reduces the risk of human error, injecting greater vitality into the market.

[0103] 5. Promoting Technological Innovation and Cross-Sector Collaboration

[0104] The application of blockchain technology has promoted the standardization of real estate information management. By using unified data formats (such as BIM models and transaction timestamps), real estate information can be efficiently integrated and used for multi-scenario analysis. For example, financial institutions can build risk assessment models based on standardized data on the blockchain to provide accurate pricing for real estate mortgages, while urban planning departments can use building information to optimize municipal resource allocation.

[0105] Furthermore, the openness and interoperability of blockchain lay the foundation for cross-platform collaboration. Different institutions (such as housing authorities, banks, and property management companies) can access the same blockchain network through authorized access, enabling seamless data sharing and collaborative management. For example, maintenance records uploaded by a property management company can be synchronized to the blockchain in real time, allowing financial institutions to directly access this information and assess the condition of properties when approving loans. This cross-domain data flow not only improves collaborative efficiency but also provides technical support for innovative service models (such as real estate securitization and shared property rights management).

[0106] This invention systematically addresses the challenges of information silos, weak security, and inefficient processes in traditional real estate information management through tamper-proof data storage, efficient information retrieval, multi-dimensional security protection, and automated transaction mechanisms. Its technical benefits are not only reflected in an optimized user experience, but also in promoting transparency, standardization, and technological innovation in the real estate market. By building a trustworthy, efficient, and open information ecosystem, this system provides a sustainable technical framework for the digital management of real estate assets and opens up new possibilities for the coordinated development of finance, government affairs, urban planning, and other fields.

[0107] In order to further illustrate the technical solution of the present invention, the key technical points of the present invention are summarized below:

[0108] This invention integrates blockchain technology with real estate information management to provide an innovative solution for the confirmation and transaction of virtual assets. The core value of this invention lies in its synergistic effect, systematically addressing the challenges of traditional real estate information management, including low transparency, weak security, and insufficient efficiency, through the synergy of multiple key technical points. The following details each key technical point and its importance from the perspectives of technical implementation, core advantages, and contribution to system performance.

[0109] 1. Innovative Applications of Blockchain Technology

[0110] Technical Implementation

[0111] The application of blockchain technology is the core foundation of this system, which is mainly reflected in the following three aspects:

[0112] Immutability: The blockchain's chained data structure and hashing algorithm ensure that once real estate information (such as ownership changes and transaction records) is written into a block, it cannot be tampered with or deleted. Every transaction is verified by a consensus mechanism, and data modifications are confirmed simultaneously by all nodes in the network, eliminating the possibility of human intervention from a technical perspective.

[0113] Distributed ledger: Data is stored in multiple nodes around the world. A failure or attack on any one node does not affect the overall system. For example, if a server in one location goes down, users can still access complete information through other nodes, ensuring service continuity and reliability.

[0114] Smart Contract Automation: Automated real estate transactions are executed through pre-programmed smart contract rules. For example, once a buyer completes payment, the contract automatically triggers the transfer of ownership and updates the on-chain record, eliminating the need for third-party intervention.

[0115] Core Advantages

[0116] Data credibility: The tamper-proof feature ensures the authenticity and integrity of information, providing a reliable data source for market participants.

[0117] Risk resistance: The distributed architecture resists single point failures and malicious attacks, significantly improving system robustness.

[0118] Efficiency optimization: Smart contracts replace manual review, shortening transaction cycles and enhancing process transparency.

[0119] System Contribution

[0120] The application of blockchain technology builds the trust foundation of the system, which not only solves the defect of traditional centralized databases being easily tampered with, but also reduces transaction costs through automated processes, providing underlying support for the expansion of subsequent functional modules.

[0121] 2. Standardized Management of 3D Apartment Information

[0122] Technical Implementation

[0123] BIM model upload: The property's 3D Building Information Model (BIM) is converted into a standardized data format and uploaded to the blockchain. The BIM model includes details such as building structure, spatial layout, and pipeline configuration, and supports 3D visualization.

[0124] Version control mechanism: Each model modification generates a new version and is recorded on-chain, forming a traceable update history. For example, after a house renovation, the updated BIM model will coexist with the original version, and users can compare and view the differences.

[0125] Core Advantages

[0126] Information visualization: 3D models provide three-dimensional display, allowing users to intuitively understand the physical status of the property and lower the threshold for information comprehension.

[0127] Historical traceability: Version management ensures that every modification can be traced, making it easier to resolve property rights disputes or audit needs.

[0128] System Contribution

[0129] The combination of BIM models and blockchain has realized the digitization and visualization of real estate information, providing technical support for the accurate description and management of virtual space assets, especially in complex transaction scenarios (such as shared property rights and space leasing).

[0130] 3. Dynamic Recording of Full Life Cycle Information

[0131] Technical Implementation

[0132] Timeline Archiving: Records of property transactions, repairs, and property changes are recorded in chronological order on the blockchain, forming a continuous historical archive. For example, all records of a property from its first transaction to its current status are arranged by timestamp.

[0133] Multi-dimensional data integration: In addition to transaction information, the system integrates maintenance records, energy consumption data, lease contracts and other diversified information to build a comprehensive real estate archive.

[0134] Core Advantages

[0135] Information integrity: Timeline records ensure that users can trace the complete life cycle of a property and avoid missing key information.

[0136] Decision support: Multi-dimensional data provides rich analytical basis for homebuyers, financial institutions, etc., such as assessing house maintenance costs through maintenance records.

[0137] System Contribution

[0138] Full life cycle management breaks through the limitations of traditional information fragmentation, provides users with a panoramic perspective, reduces decision-making risks caused by missing information, and lays the foundation for derivative services (such as real estate valuation and insurance pricing).

[0139] 4. Convenient and efficient information retrieval mechanism

[0140] Technical Implementation

[0141] QR code / NFC identification: A unique identification code is generated for each asset, and users can trigger information query requests by scanning the code or using near-field communication (NFC). For example, a homebuyer can scan the QR code of a house to obtain all the associated data stored on the chain.

[0142] Multi-factor authentication: When accessing sensitive information, identity verification must be completed through a password, biometrics (such as fingerprint) or dynamic verification code to ensure controllable access rights.

[0143] Core Advantages

[0144] Convenience of operation: Scanning the QR code to retrieve information replaces the traditional cross-institutional application process, shortening the time to obtain information from several days to minutes.

[0145] Privacy protection: Authentication mechanisms prevent unauthorized access, for example, only the property owner can view detailed maintenance records.

[0146] System Contribution

[0147] This mechanism significantly optimizes the user experience while balancing the needs of information openness and privacy protection, providing an efficient tool for high-frequency, high-concurrency market transaction scenarios.

[0148] 5. Multi-layered security architecture design

[0149] Technical Implementation

[0150] Data encryption transmission: Use asymmetric encryption technology (such as RSA) to protect the data transmission process and prevent man-in-the-middle attacks or information theft.

[0151] Distributed disaster recovery backup: Data copies are stored in multiple nodes around the world and updated regularly to ensure that single point failures do not affect service continuity.

[0152] Dynamic permission control: Differentiated access rights are assigned based on user roles (such as ordinary users and administrators), and sensitive operations require multiple authentications.

[0153] Core Advantages

[0154] End-to-end security: Encryption throughout the entire process from data storage to transmission to ensure information confidentiality and integrity.

[0155] High system availability: The distributed architecture supports 24 / 7 uninterrupted service, with annual downtime close to zero.

[0156] System Contribution

[0157] The security architecture design builds a defense barrier for the system, which not only resists external attacks but also prevents internal unauthorized operations, providing reliability guarantees for large-scale commercial applications.

[0158] The key technical points of the present invention revolve around the in-depth application of blockchain technology. Through 3D information management, full life cycle recording, efficient retrieval mechanism and security architecture design, an efficient, transparent and trustworthy virtual space asset management system is constructed. These technical points not only solve the problems of information islands, easy tampering and inefficiency in traditional real estate information management, but also provide a standardized interface for cross-domain collaboration (such as finance, government affairs, and the Internet of Things). For example, financial institutions can develop intelligent risk control models based on on-chain data, and government agencies can monitor market transaction dynamics in real time. In the future, with the iteration of blockchain technology and the integration of multimodal data, this system is expected to further promote the digital and intelligent transformation of real estate assets, and provide continuous impetus for building a transparent and healthy real estate market ecosystem.
