[0024] 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.

[0025] See also Figure 1 The figure shows a schematic diagram of a digital asset management and control platform based on the Web3 framework in a specific embodiment. The platform includes: The decentralized identity authentication module is used to provide users with an operation interface for creating identity information, store the identity information entered by users, configure login verification credentials for the identity information, and authorize the identity information.

[0026] In this embodiment, the decentralized identity authentication module includes: a user identity generation unit, which is used to generate an identity identifier from the identity information input by the user; a user identity authentication unit, which is used to verify the identity identifier and login verification credentials that match the identity information of the login access, and match the access rights for the logged-in user who has passed the verification; a user identity management and control unit, which receives the user's operations of adding, deleting, modifying and checking the identity information based on the identity information operation interface.

[0027] In some embodiments, a digital asset operation interface is configured to allow users to enter identity-related information, such as name, email address, public key, etc. The platform has a database that can store the identity information entered by the user: using blockchain technology, the identity information entered by the user is encrypted and stored on the blockchain to ensure the immutability and security of the data. A distributed storage solution can be used to store larger data files, and the hash value of the file is stored on the blockchain.

[0028] This embodiment can use a public key / private key pair or a mnemonic phrase as the user's login verification credential. When a user creates identity information, a pair of public keys and private keys are generated for the user.

[0029] For identity information authorization, you can configure the authorization mechanism to allow users to control access to their identity information. Smart contracts can be used to manage the authorization logic to ensure that only authorized entities can access sensitive information.

[0030] The smart contract management module is used to provide users with an interface for setting issuance, trading and management rules for digital assets, obtain issuance, trading and management rules for storage, and manage and control transactions of digital assets based on issuance, trading and management rules.

[0031] In some embodiments, a digital asset issuance, transaction and management rule setting interface is provided to users for setting the configuration, transaction and management rules of digital assets. Users can define the quantity, price, transaction conditions, permission control and other parameters of assets through the interface.

[0032] Optionally, this embodiment can collect the rule data set by the user in the interface, and perform necessary verification and formatting, and store the processed rule data on the blockchain to ensure the immutability and security of the data.

[0033] When a digital asset transaction request occurs, the smart contract management module will automatically retrieve and execute the corresponding rules. Based on the rules, the module will determine whether the transaction meets the conditions, such as whether the asset quantity is sufficient, whether the transaction parties have the corresponding permissions, etc. If the transaction meets the conditions, the module will execute the transaction and update the asset status on the blockchain; otherwise, the transaction will be rejected.

[0034] The multi-chain interoperability module of this embodiment is used to provide digital asset transfer between multiple blockchains.

[0035] In some embodiments, digital assets can be transferred from one blockchain to another through a cross-chain bridge to achieve cross-chain interaction. Double payments and other potential security risks can be prevented. Optionally, trustless asset exchanges can be allowed on different blockchains based on atomic swaps, thereby ensuring the security and reliability of transactions. In order to achieve interoperability between different blockchains, an interoperability protocol is defined. The interoperability protocol enables communication and data exchange between different blockchains, thereby ensuring that digital assets can be smoothly transferred between different blockchains.

[0036] According to actual needs, the platform of this embodiment may also include: a user operation display interface module; the user operation display interface module includes: a user registration and login unit, used to provide a user registration and login operation interface; a digital asset management unit, used to provide a digital asset operation interface; a transaction record query unit, used to provide a user's transaction record query interface.

[0037] The digital asset encryption and decryption module is used to provide users with an encryption operation interface, set the encryption process, encrypt and protect the digital asset transaction process, and encrypt and save the digital assets.

[0038] In some specific embodiments, the digital asset encryption and decryption module receives a query request or a transaction request sent by the digital asset processing module.

[0039] In this embodiment, the digital asset operation terminal is used by users to perform operations such as trading or querying digital assets. The digital asset processing module of the platform is used to obtain the user's request for digital asset processing. The request for digital asset processing can be a query request or a transaction request retrieved from the memory.

[0040] The digital asset encryption and decryption module of this embodiment generates a digital asset processing key in a preset manner in response to a query request or a transaction request, and encrypts the unencrypted digital asset based on the digital asset processing key to obtain a first encrypted digital asset.

[0041] In this embodiment, the digital asset encryption and decryption module first receives a query request or a transaction request from the digital asset processing module. The request includes a query instruction or a transaction instruction for a specific digital asset. In response to the received request, the digital asset encryption and decryption module generates a digital asset processing key in a preset manner.

[0042] The digital asset processing key of this embodiment is used for the digital asset processing process of the current request, ensuring the independence and security between different requests. The method of generating the key may include using a secure random number generator, a hash function based on the request parameters, etc. to ensure the complexity and unpredictability of the key. Once the digital asset processing key is generated, the digital asset encryption and decryption module will use the key to perform encryption operations on the unencrypted digital assets. The encryption process may use a symmetric encryption algorithm or an asymmetric encryption algorithm to ensure that the digital assets are not accessed or tampered with by unauthorized personnel during transmission and storage. After completing the encryption operation, the digital asset encryption and decryption module will output the first encrypted digital asset. This encrypted digital asset is safe and can be transmitted in the network or stored in the database without worrying about being stolen or tampered with.

[0043] The digital asset encryption and decryption module of this embodiment queries the terminal public key of the digital asset operation terminal, encrypts the digital asset processing key using the terminal public key, and obtains the terminal ciphertext corresponding to the digital asset operation terminal. The digital asset encryption and decryption module is configured to generate the terminal public key of the digital asset operation terminal and the private key corresponding to the terminal public key. The terminal public key can be publicly displayed to users using the digital asset operation terminal.

[0044] In this embodiment, the digital asset encryption and decryption module can encrypt the digital asset processing key based on the RSA algorithm encryption algorithm to obtain the terminal ciphertext corresponding to the digital asset operation terminal.

[0045] The digital asset encryption and decryption module of this embodiment combines the terminal ciphertext with the first encrypted digital asset, configures it into a second encrypted digital asset, and transmits it to the digital asset operation terminal.

[0046] In this embodiment, in the digital asset management and control platform based on the Web3 framework, the interaction between the digital asset encryption and decryption module and the digital asset processing module is the key link to ensure the security and privacy of digital assets. When the digital asset encryption and decryption module receives a query request or transaction request from the digital asset processing module, it will perform a series of operations to protect the security of digital assets.

[0047] In this embodiment, the digital asset encryption and decryption module first receives a query request or transaction request from the digital asset processing module. The digital asset encryption and decryption module generates a digital asset processing key according to a preset method. The unencrypted digital asset is encrypted using the key to obtain a first encrypted digital asset. The digital asset encryption and decryption module also prepares or receives a terminal ciphertext. The terminal ciphertext is used to verify the encrypted information of the identity or authority of the digital asset operation terminal, or is additional security data related to a specific transaction or query. The digital asset encryption and decryption module combines the first encrypted digital asset with the terminal ciphertext. The combination method may include connecting the two in series, mixing them using a hash function, or fusing them together through a certain encryption algorithm to form a new encryption structure. The combined data is configured as a second encrypted digital asset. The second encrypted digital asset not only contains the encryption information of the digital asset, but also incorporates the security verification data related to the operation terminal. After completing the encryption configuration, the second encrypted digital asset is sent to the digital asset operation terminal. After receiving the second encrypted digital asset, the digital asset operation terminal will use the corresponding key and algorithm to decrypt and process it. Only a terminal with the correct key and verification information can successfully decrypt the second encrypted digital asset and access the original digital asset data therein.

[0048] Through the above process, the digital asset management and control platform based on the Web3 framework ensures the dual security of digital assets during transmission and processing: it protects the content of the digital assets from being leaked or tampered with, and verifies the legitimacy and authority of the operating terminal. This encryption and decryption mechanism is an important means to protect digital assets from unauthorized access and potential security threats.

[0049] For the transaction request of this embodiment, a second encrypted digital asset is generated accordingly, and the second encrypted digital asset is configured to the digital asset operation terminal.

[0050] In this embodiment, the digital asset encryption and decryption module adds the terminal ciphertext to the preset position of the first encrypted digital asset to generate the second encrypted digital asset. It should be noted that the digital asset has the first symbol, the last symbol and the middle separator, and the terminal ciphertext can be randomly added to any position to meet the security requirements. Of course, it can also be added to the preset position according to actual needs.

[0051] The digital asset encryption and decryption module of this embodiment receives a data decryption request for the second encrypted digital asset submitted by the digital asset operation terminal.

[0052] The digital asset encryption and decryption module of this embodiment parses the terminal ciphertext and the first encrypted digital asset from the second encrypted digital asset in response to the data decryption request.

[0053] In this embodiment, the digital asset encryption and decryption module responds to the data decryption request, parses the second encrypted digital asset targeted by the data decryption request, and parses the terminal ciphertext and the first encrypted digital asset from the second encrypted digital asset according to the preset data combination method used by the second encrypted digital asset. If the second encrypted digital asset is generated by adding, it is determined to parse the terminal ciphertext from the preset position of the second encrypted digital asset, and the remaining data portion in the second encrypted digital asset after parsing the terminal ciphertext is used as the first encrypted digital asset, thereby completing the parsing of the terminal ciphertext and the first encrypted digital asset.

[0054] The digital asset encryption and decryption module of this embodiment obtains the private key corresponding to the terminal public key of the digital asset operation terminal, and uses the private key to decrypt the terminal ciphertext to obtain the digital asset processing key.

[0055] The digital asset encryption and decryption module of this embodiment uses the digital asset processing key to decrypt the first encrypted digital asset to obtain an unencrypted digital asset.

[0056] Since the first encrypted digital asset is obtained by encrypting the unencrypted digital asset using the digital asset processing key according to a symmetric encryption algorithm, the decryptable digital asset processing key can be used to decrypt the first encrypted digital asset according to the inverse algorithm of the preset encryption algorithm, thereby conveniently obtaining the unencrypted digital asset.

[0057] The digital asset management and control platform based on the Web3 framework achieves efficient and secure management and control of digital assets through a series of operations of its digital asset encryption and decryption module. It ensures the security and privacy of digital assets during transmission, processing and storage, while providing a flexible and reliable data encryption and decryption mechanism. In addition, through multiple encryption mechanisms, including encrypting unencrypted digital assets with digital asset processing keys and re-encrypting digital asset processing keys with terminal public keys, the security of digital assets is enhanced. The platform is designed so that only digital asset operation terminals with corresponding private keys can decrypt and access their corresponding digital assets, thereby effectively protecting users' privacy and data sovereignty. Unauthorized access and leakage are prevented.

[0058] In an exemplary embodiment, the smart contract management module includes: Smart contract writing unit, used to provide a contract operation interface for users to write and deploy smart contracts; A smart contract execution unit, which is used to automatically execute the transaction logic in the smart contract according to the preset smart contract; The smart contract audit unit is used to review the logic of the smart contract in the digital asset transaction process; the code of the smart contract is reviewed, including: the syntax and structure of the transaction check code and whether there are any abnormal codes.

[0059] The code review in this embodiment is to review the code of the smart contract. The syntax, structure, logic and potential security vulnerabilities of the code can be checked. Verify whether the functions of the smart contract meet expectations. This includes testing the behavior of the contract under various conditions to ensure that it can be correctly executed according to the design requirements.

[0060] In the audit process of this embodiment, it is crucial to conduct security analysis on smart contracts. This includes identifying and evaluating possible security risks in the contract, such as reentrancy attacks, overflow vulnerabilities, privilege escalation, etc. Security analysis may involve using automated tools for static code analysis, as well as dynamic analysis to detect runtime security issues.

[0061] Compliance checks are conducted to check whether smart contracts comply with relevant laws, regulations and industry standards. This includes ensuring that the content of the contract, transaction logic and data processing methods comply with requirements in terms of privacy protection, anti-money laundering and anti-terrorist financing.

[0062] In some specific embodiments, the smart contract management module also includes: a compliance check unit, which is used to obtain the current transaction requirement information, extract keywords in the transaction requirement information, compare the transaction keywords in the digital asset transaction process with the keywords in the transaction requirement information, and determine whether they comply with laws and regulations; a legal and regulatory update unit, which is used to update the transaction requirement information in real time; a historical transaction process comparison unit, which is used to obtain historical transaction process information and currently ongoing transaction process information; configure transaction requirement information based on historical transaction process comparison and similar transaction process comparison; historical transaction process comparison is based on obtaining historical transaction process templates, extracting transaction process items and transaction parameter information of the historical transaction process templates, and comparing them with the current digital asset transaction process information; similar transaction process comparison refers to comparing similar digital asset transaction processes in progress, and judging that they are similar processes, then judging the transaction process items and transaction parameter information.

[0063] In one embodiment of the present invention, a digital asset management and control platform based on the Web3 framework is provided below as a possible embodiment to provide a non-limiting explanation of its specific implementation scheme.

[0064] The digital asset management and control platform also includes: a risk management module; a risk management module for obtaining transaction process items and transaction parameter information of a transaction process template to obtain transaction feature data corresponding to the characteristics of abnormal digital asset transaction status; using a pre-trained digital asset risk transaction analysis model to analyze the transaction feature data to obtain the risk results of both parties to the transaction; obtaining abnormal objects in the transaction data based on the risk results of both parties to the transaction; and real-time monitoring of abnormal objects.

[0065] In this embodiment, the risk management module also analyzes each digital asset risk event through a preset algorithm to obtain multiple digital asset transaction risk factors; according to the preset digital asset transaction risk rules, the weighted score of each digital asset transaction risk factor is configured, and the weighted score is assigned to the digital asset transaction risk factor.

[0066] The preset digital asset transaction risk rule is the digital asset transaction relationship between each digital asset transaction risk factor and the probability of occurrence of the current preset digital asset transaction risk event, and the digital asset transaction relationship is expressed as a weighted score.

[0067] The digital asset transaction risk factors are combined into transaction risk factors, and the combined transaction risk factors are evaluated according to the preset risk calculation rules to obtain the risk of the combined transaction risk factors.

[0068] The preset risk calculation rule is to obtain the digital asset transaction risk score based on the weighted scores of all digital asset transaction risk factors in each combination. The digital asset transaction risk score can represent the size of the digital asset transaction risk of the digital asset transaction risk set; the digital asset transaction risk represents the possibility of the current preset digital asset transaction risk event occurring when the combination conditions are met.

[0069] According to the riskiness of digital asset transactions, multiple combined transaction risk factors are summarized into risk sets of different risk levels.

[0070] In this embodiment, through the transaction process simulation algorithm, the digital asset transaction risk factor is used as a variable, and experiments are continuously conducted to control the value of the digital asset transaction risk factor, so as to obtain the relationship between the current type of digital asset transaction risk factor and the probability of occurrence of the current preset risk event based on the simulation results, and then traverse to obtain the relationship between all digital asset transaction risk factors and preset risk events.
