Description

Technical Field

[0001] The present disclosure relates to the field of blockchain technology, and in particular to a blockchain-based asset processing system, method, and device. Background Art

[0002] Based on blockchain technology, real-world assets (RWA) are represented and traded in a digital and tokenized manner, such as real estate, commodities, bonds, stocks, artworks, intellectual property, etc.

[0003] In some related technologies, the digital model of real-world assets is a cross-shaped model, such as Figure 1 In the physical space, asset licensing, asset audit / assessment, digital representation, asset circulation, and circulation supervision are carried out; in the digital space, asset selection, value determination, digital representation, issuance, trading, and management are carried out.

[0004] Research has found that physical and digital assets only intersect at a single point, lacking synchronization across every process. This can easily lead to transaction risks. For example, there's the risk of counterfeit assets: Before issuance, the assets are genuine and there's sufficient evidence. However, after issuance, they're privately transferred or secretly pledged to other banks, leaving no real-world assets behind in subsequent processes. Summary of the Invention

[0005] This paper proposes a dual-blockchain asset management solution: a physical blockchain managed by regulatory authorities, and a digital blockchain managed through smart contracts. Real-world assets managed by the physical blockchain are dynamically mapped to digital credentials managed by the digital blockchain throughout their lifecycle. The physical and digital blockchains synchronize data bidirectionally based on oracles and dynamic hash consistency constraints. This reduces transaction risks. For example, asset transfers or mortgages are reflected on the physical blockchain through regulatory oversight, and then on the digital blockchain through mapping and synchronization, thus mitigating the risk of counterfeit assets.

[0010] In some embodiments, when it is detected that the hash values ​​of the physical space operation and the digital space operation of the real-world asset are inconsistent, the operation of the corresponding token of the real-world asset is frozen.

[0011] In some embodiments, the model information of the digital certificate includes issuance model information. When the issuance model information is a linear profit distribution model, the smart contract corresponding to the issuance model information is configured to distribute the total profit according to the proportion of the token in the total amount of tokens.

[0039] To address transaction risk issues in related technologies, this paper proposes a dual-track parallel model for the digitization of real-world assets, referred to as the dual-track parallel model. Real-world assets include real estate, commodities, bonds, stocks, artwork, intellectual property, etc.

[0040] Figure 2 A schematic diagram of a blockchain-based asset processing system showing a dual-track parallel model according to some embodiments of the present disclosure.

[0041] like Figure 2As shown, the asset processing system consists of a physical blockchain, managed by regulatory authorities, and a digital blockchain, managed through smart contracts. Real-world assets managed by the physical blockchain are dynamically mapped to digital credentials managed by the digital blockchain throughout their lifecycle. The physical and digital blockchains synchronize data bidirectionally based on oracles and dynamic hash consistency constraints. This reduces transaction risks. For example, asset transfers or mortgages are reflected on the physical blockchain through regulatory oversight, and then on the digital blockchain through mapping and synchronization, thus mitigating the risk of counterfeit assets.

[0042] (1) Dual-track parallel model: The two tracks are parallel throughout the entire process, which means that the physical space and digital space are fully connected.

[0043] (2) Dual-track information consistency: The physical and digital spaces maintain consistency throughout the entire process. Changes in the digital space notify the physical space, and changes in the physical space notify the digital space. The dual-track parallel model integrates digital assets and real-world assets, and is fully consistent throughout the entire life cycle.

[0044] (3) Synchronous: Actions on the two tracks are synchronized, whether moving forward or stopping.

[0045] (4) Timely processing: If an abnormality occurs in any space, all participating nodes on both tracks will be notified at the same time and the abnormality will be handled immediately.

[0046] (5) Dual-track supervision: The physical space is managed by the regulatory agency, which manages the entire system. The regulatory agency can also obtain information notifications from the digital space and promptly understand and control the status of the digital space.

[0047] (6) High-trust operation: The physical space and the digital space are maintained by two different blockchain systems to avoid the collapse of the entire RWA system due to the paralysis of a single system.

[0048] (7) Value protection: The generation or destruction of digital certificates is carried out in the digital space, but all real-world assets are in the physical space, not the digital space, to avoid asset losses due to problems with the digital system.

[0049] The RWA process in the physical space consists of six steps, which are executed and processed by the first, second, third, fourth, fifth, and sixth nodes of the physical space blockchain. The first four steps are executed before the digital certificate is issued, and the last two steps are executed after the digital certificate is issued.

[0050] Step 1 (pre-issuance): Select a real-world asset and apply for a license to engage in digital assets. In other words, apply for the digital tokenization of the real-world asset.

[0051] Project owners must select appropriate real-world assets and store the relevant information on-chain (in physical blockchain space). After reviewing the real-world assets to ensure they are free of legal disputes and their owners are clear on the lack of collateral, they must apply for permission from relevant authorities to engage in digital asset trading, thereby enabling the digitalization of real-world assets.

[0052] Step 2 (Pre-issuance): Assess the value of the asset. A third party or online assessment system will objectively and impartially assess the value of the real-world asset. Project owners must provide an asset valuation report for the real-world asset, which will be stored on the physical blockchain.

[0053] Step 3 (pre-issuance): Create a contract to bind the real-world asset to the digital certificate. This contract is also called a binding contract.

[0054] The project owner and the real-world asset owner sign a contract, agreeing that the real-world asset will serve as the counterpart for the digital certificate. This step is a reliable guarantee that the digital certificate has value.

[0055] Step 4 (before issuance): Develop model information for the digital certificate, such as issuance model information and transaction model information.

[0056] Project owners need to develop a digital certificate (digital economy) model, design the digital certificate share and transaction model based on the contract and the total value of the assets, and develop relevant smart contracts based on the model. Here are some examples.

[0057] The model information of the digital certificate includes the issuance model information. In the case where the issuance model information is a linear revenue distribution model, the smart contract corresponding to the issuance model information is configured to distribute the total revenue according to the proportion of the tokens in the total number of tokens.

[0058] The model information of the digital certificate includes transaction model information, and the transaction model information includes at least one of decentralized transaction model information and time-sharing leasing model information.

[0059] The smart contract corresponding to the decentralized transaction model information is configured to respond to transaction requests initiated by users for tokens, check whether the balance in the user's account is greater than or equal to the payment amount and whether the owner of the token is the issuer. If the check items meet the requirements, the ownership of the token is updated from the issuer to the user.

[0060] The smart contract corresponding to the time-sharing leasing model information is configured to dynamically determine the price adjustment coefficient of the token based on the real-time supply and demand information of the token, and determine the current price of the token based on the price adjustment coefficient of the token.

[0061] Step 5 (post-issuance): Record transaction information of digital assets.

[0062] Step 6 (Post-Issuance): Automatically report transaction data to regulators.

[0063] Table 1 below shows the RWA physical space flow.

[0064] Table 1 RWA physical space process

[0065] The RWA process in the digital space consists of six steps, each of which is executed and processed by the first, second, third, fourth, fifth, and sixth nodes of the digital space blockchain. The first four steps are performed before the digital certificate is issued, while the last two steps are performed after the digital certificate is issued.

[0066] Step 1 (before issuance): The digital space blockchain stores the asset information and licensing information of real-world assets.

[0067] Digital spaces (such as digital asset trading platforms) need to record the (asset) information and licensing information (such as licenses) of real-world assets provided by the project party on the blockchain system (digital space blockchain) to ensure that the asset information is authentic and reliable.

[0068] Step 2 (before issuance): The digital space blockchain stores the asset valuation information (asset valuation report) of real-world assets.

[0069] The digital asset trading platform records the third-party asset appraisal report, or can also provide online asset appraisal and record the asset appraisal information in the digital space blockchain.

[0070] Step 3 (before issuance): The digital space blockchain stores the binding information (binding contract) between real-world assets and digital certificates as the basis for issuing digital certificates.

[0071] The digital asset trading platform saves the binding contract that combines real-world assets and digital certificates to the digital space blockchain as the legal basis for issuing digital certificates, ensuring the openness and transparency of the contract.

[0072] Step 4 (Pre-issuance): The digital space blockchain stores the model information of the digital certificate and its corresponding smart contract. For example, this includes issuance model information, transaction model information, and corresponding smart contracts. For details, please refer to the description of the fourth step of RWA in the physical space, which will not be repeated here.

[0073] Step 5 (Post-Issuance): The digital asset platform executes digital asset issuance and transactions, and relevant information is recorded in the digital space blockchain. The digital space blockchain can be synchronized to the physical space blockchain, allowing relevant institutions or customers in the physical space to find relevant information through the platform or blockchain system.

[0074] Step 6 (after issuance): The digital asset platform supervises digital certificate transactions, for example: verifying customer identity, ensuring its authenticity and legality, preventing illegal funds from being "legalized" through the financial system, etc., and recording relevant data in the digital space blockchain. The digital space blockchain can be synchronized to the physical space blockchain, so that relevant institutions or customers in the physical space can find relevant information through the platform or blockchain system.

[0075] Table 2 below shows the RWA digital space flow.

[0076] Table 2 RWA digital space process

[0077] The following Table 3 compares the RWA physical space process and the RWA digital space process.

[0078] Table 3 Comparison of RWA physical space process and RWA digital space process

[0079] According to the previous description of the RWA physical space process and the RWA digital space process and their comparison, the dual blockchains in the blockchain-based asset processing system (blockchain system for asset processing) can be set up as follows.

[0080] The physical space blockchain includes at least one pre-issuance node and at least one post-issuance node; the digital space blockchain includes at least one pre-issuance node and at least one post-issuance node; the issuance is the issuance of digital certificates; among them, the physical space blockchain is the dominant factor, and the mapping of the pre-issuance node of the physical space blockchain to the pre-issuance node of the digital space blockchain is carried out; the digital space blockchain is the dominant factor, and the mapping of the post-issuance node of the physical space blockchain to the post-issuance node of the digital space blockchain is carried out.

[0081] The pre-issuance node includes at least one of a first node, a second node, a third node, and a fourth node.

[0082] The first node of the physical space blockchain stores the review materials and review results of the real-world assets and the licensing information when the review is passed, and maps the information and licensing information of the real-world assets to the first node of the digital space blockchain. The first node of the digital space blockchain stores the information and licensing information of the real-world assets.

[0083] The second node of the physical space blockchain stores the asset evaluation information of the real-world assets, and maps the asset evaluation information of the real-world assets to the second node of the digital space blockchain, and the second node of the digital space blockchain stores the asset evaluation information of the real-world assets.

[0084] The third node of the physical space blockchain binds real-world assets and digital certificates, and maps the binding information to the third node of the digital space blockchain. The third node of the digital space blockchain stores the binding information of real-world assets and digital certificates as the basis for issuing digital certificates.

[0085] The fourth node of the physical space blockchain stores the model information of the formulated digital certificate, maps the model information to the fourth node of the digital space blockchain, and the fourth node of the digital space blockchain stores the smart contract corresponding to the model information and issues the digital certificate.

[0086] The post-issuance node includes at least one of the fifth node and the sixth node.

[0087] The fifth node of the digital space blockchain conducts transactions of digital certificates, records transaction information, and maps the transaction information to the fifth node of the physical space blockchain. The fifth node of the physical space blockchain stores the transaction information of the digital certificate.

[0088] The sixth node of the digital space blockchain supervises digital certificate transactions, records regulatory information, and maps the regulatory information to the sixth node of the physical space blockchain. The sixth node of the physical space blockchain stores the regulatory information of digital certificate transactions and reports it to the regulatory agency.

[0089] Figure 3 A schematic diagram illustrating the asset processing flow before issuing digital certificates according to some embodiments of the present disclosure is provided. To initiate the digital certificateization of a real-world asset, the following steps are performed.

[0090] In step 301, select a real-world asset, apply for a license to engage in digital assets, and submit the corresponding materials.

[0091] In step 302, the relevant departments review the materials and upload the materials and review results to the blockchain system (first upload to the physical space blockchain, and then the physical space blockchain is synchronized to the digital space blockchain).

[0092] Determine whether all the materials have been reviewed and approved. If not, you can resubmit the materials and reapply, that is, re-execute from step 301. If all the materials have been reviewed and approved, you can continue to step 303.

[0093] At step 303, the asset value and price are assessed.

[0094] For example, having the asset value and price assessed by a third party or online.

[0095] The evaluation is judged to be passed or not according to whether the evaluation is reasonable. For example, if the price deviates significantly from the value, the evaluation is not reasonable. If the evaluation fails, step 303 is repeated. If the evaluation passes, step 304 is continued.

[0096] At step 304, a contract is developed to bind the real-world asset to the digital credential.

[0097] In step 305, model information of the digital certificate is formulated, including, for example, issuance model information and transaction model information.

[0098] Determine whether the system joint debugging test passes. If the test fails, adjust the model or modify the smart contract. If the test passes, a digital certificate can be issued (step 306).

[0099] Figure 4 A schematic diagram illustrating the asset processing flow after the issuance of a digital certificate according to some embodiments of the present disclosure is shown. The following steps may be performed after the issuance of a digital certificate for a real-world asset.

[0100] In step 401, digital assets (digital certificates) are traded and circulated online.

[0101] In step 402, digital asset transaction information is recorded.

[0102] In step 403, digital asset transaction information is automatically reported to the regulatory authorities.

[0103] In step 404, the regulatory agency checks whether the digital asset transaction is compliant.

[0104] In step 405, if compliance is met, the digital asset transaction information and regulatory information are recorded in the blockchain system (first recorded in the digital space blockchain, and then synchronized to the physical space blockchain).

[0105] In step 406, if there is non-compliance, the circulation of the digital certificate is stopped.

[0106] The following describes some technical details of the above processes.

[0107] Physical space assets (real world assets): Let the asset set be ,in represents the i-th asset.

[0108] Digital space certificate (digital certificate): the digital certificate set corresponding to the asset set is ,satisfy ,in A tokenization function. A digital certificate for an asset can correspond to one or more tokens.

[0109] Blockchain network: defined as a graph G = (V, E), where the node set V includes project parties (such as educational institutions), regulators, (third-party) evaluation agencies, etc., and the edge set E represents the communication and consensus protocol between nodes.

[0110] Hash function: , mapping real-world asset information into a fixed-length hash value.

[0111] Smart contract: represented as a state machine S, whose state transition function is , where I is input and O is output.

[0112] The following describes the issuance model information, that is, the mathematical modeling information of the issuance process.

[0113] (1) Asset selection and review

[0114] Physical space process:

[0115] Asset Selection: Select an asset , meeting the legality conditions , that is, the assets really exist.

[0116] Hash on-chain: calculation , and Write to the blockchain and generate transactions , Indicates a timestamp.

[0117] Relevant departments review: Relevant departments review the assets Conduct review and generate license ,license Hash value Synchronize to the blockchain.

[0118] Mathematical constraints: (1)

[0119] The above formula means: for each element in set A ( ), there is a corresponding Belongs to the set T ( ),like The hash value is ,Right now ,and and Match, that is , then assert integrity, (i.e. it has not been tampered with).

[0120] (2) Asset valuation

[0121] Evaluation function: Assume that the evaluation agency The value assessment is ,in To evaluate the model.

[0122] On-chain synchronization: evaluation results are obtained through oracle Enter the blockchain to generate the total amount of tokens ,in The minimum transaction unit.

[0123] (3) Contract binding of assets and digital certificates

[0124] Contract encryption: signing paper contracts , the encrypted contract is stored as ,contract Hash The data is stored in a blockchain system (first in the physical blockchain and then synchronized to the digital blockchain). ZKP stands for Zero-Knowledge Proof, a cryptographic technique that allows one party (the prover) to prove to another party (the verifier) ​​that a statement is true without revealing the specific information.

[0125] (4) Issuance model and its smart contract deployment

[0126] When the issuance model information is a linear profit distribution model, the corresponding smart contract logic of the issuance model information is: define the profit distribution rule as a linear function, and distribute the total profit according to the proportion of the token in the total number of tokens.

[0127] Right now, (2)

[0128] in, It is a token The share of income that the holder should receive , defines a linear profit distribution rule for allocating asset profits proportionally in smart contracts, Is a token, which is an asset Corresponding token set , It is an asset The corresponding total amount of tokens, is the total income (such as interest, dividends, rent, etc.).

[0129] The following describes the transaction model information, which is the mathematical modeling information of the transaction process. The transaction model information includes decentralized transaction model information, time-sharing leasing model information, etc.

[0130] Decentralized trading model

[0131] The smart contract corresponding to the decentralized transaction model information is configured to respond to transaction requests initiated by users for tokens, check whether the balance in the user's account is greater than or equal to the payment amount and whether the owner of the token is the issuer. If the check items meet the requirements, the ownership of the token is updated from the issuer to the user.

[0132] For example, user For tokens Initiate purchase request B ,in To pay the amount, the smart contract checks the following conditions:

[0133] (3)

[0134] That is, users Account balance Payment amount , and the token Owner Is the issuer .

[0135] Status transfer: If the check item meets the requirements, update the ownership and account balance:

[0136] (4)

[0137] That is, tokens Ownership is held by the issuer Users who become buyers ,user The account balance decreases .

[0138] Time-sharing leasing model:

[0139] Time Sharing: Device Usage Tokens The time window is , whose value is linearly related to time:

[0140] (5)

[0141] in is the time value density function, the token The value function of , which is linearly related to time.

[0142] Dynamic pricing: adjusting prices based on supply and demand The smart contract corresponding to the time-sharing leasing model is configured to dynamically determine the token price adjustment coefficient based on the real-time supply and demand information of the token, and then determine the current price of the token based on the token price adjustment coefficient.

[0143] , (6)

[0144] in, is the market adjustment coefficient, based on the token Demand and supply The ratio is determined by using Tokens Initial price Adjust to get the current price .

[0145] For the dual-blockchain model, consistency verification can be used to achieve synchronization between physical space and digital space.

[0146] Physical space operation and digital space operations ,satisfy:

[0147] (7)

[0148] That is, for physical space operations , there is a corresponding digital space operation If the hash values ​​of the two are the same , the physical space is synchronized with the digital space.

[0149] Otherwise, if the hash values ​​of the two are detected to be inconsistent, , indicating anomaly detection, triggering the freeze function:

[0150] (8)

[0151] That is, the frozen function Suspended assets Corresponding token set All tokens in operation.

[0152] Formal verification of smart contracts, using formal methods to verify that the contract has no loopholes.

[0153] (9)

[0154] That is, the precondition is met in the initial state Under the condition of a token state (usually empty or with initial constraints), after the smart contract's function or operation δ(S, I) (where S is the contract state and I is the input) executes, the final state satisfies the postcondition ψ (i.e., the safety property holds). Preconditions include, for example, the correct total supply and zero balances when the token contract is initialized. Contract state S can be, for example, variable values ​​or stored data. Input I can be, for example, user input or transaction calls (e.g., transfer amount, caller address). Smart contract function logic δ can include transfers and subtractions. Postconditions include, for example, no integer overflow, function permission control, and asset conservation.

[0155] Assumption: In a dual blockchain, one of them is , and the other is a chain , cross-chain operations are defined as mapping ,satisfy:

[0156] (10)

[0157] chain Storing original certificates of real-world assets ,chain Used to issue and manage digital certificates , cross-chain mapping , forward mapping , the original certificate Mapping to Chain Digital certificate on . Reverse verification ,pass Reverse query to the original certificate , and verify its authenticity.

[0158] The asset issuance and transaction process based on the RWA track model achieves strict mapping of physical space and digital space through a dual-track synchronization mechanism and blockchain technology, ensuring the authenticity and consistency of assets, realizing automated transactions and compliance supervision as well as dynamic resource optimization, and improving asset utilization.

[0159] The process for bidirectional data synchronization between physical and digital blockchains, based on oracles and dynamic hash consistency constraints, is as follows: each chain maintains a dynamic hash value representing its current state; an oracle monitors the dynamic hashes of both chains; when a hash inconsistency is detected, the oracle triggers the synchronization process; hash differences are compared to determine the data range to be synchronized; bidirectional data synchronization is performed and the hash value is updated. This mechanism achieves efficient and reliable dual-chain data synchronization while maintaining the decentralized nature of blockchain.

[0160] A dual blockchain system (physical and digital) enables dynamic mapping of physical assets and digital credentials throughout their lifecycle. The physical chain is maintained by regulatory authorities, recording audit, contract, and status change data. The digital chain manages token issuance and trading through smart contracts. The two chains achieve bidirectional data synchronization based on oracles and dynamic hash consistency constraints. A cross-spatial anomaly detection mechanism identifies deviations between physical and digital states in real time, triggering a freeze on both tracks and initiating off-chain audits to prevent risk from spreading. A dynamic pricing model built into the smart contract adjusts token yield rules based on real-time data from physical assets, improving asset utilization. Zero-knowledge proofs are used for privacy protection. The dual-chain architecture isolates physical audit and digital transaction risks, ensuring that failures on any one chain do not impact system operation, enabling secure, compliant, and efficient circulation in high-concurrency scenarios.
