Description

Technical Field

[0001] This disclosure relates to the field of blockchain technology, and in particular to a blockchain-based asset processing system, method, and apparatus. Background Technology

[0002] Based on blockchain technology, real-world assets (RWAs) are represented and traded digitally, such as real estate, commodities, bonds, stocks, artwork, and intellectual property.

[0003] In some related technologies, the digital model of real-world assets is a cross-shaped model, such as... Figure 1 As shown. In the physical space, asset licensing, asset verification / evaluation, 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 share only one point of intersection and are not synchronized at every stage of the process, which can easily lead to transaction risks. For example, there is the risk of fictitious assets: before issuance, the assets may be real and there may be sufficient evidence, but after issuance, the assets may be privately transferred or secretly pledged to other banks, resulting in the absence of real-world assets in later processes. Summary of the Invention

[0005] This disclosure proposes a dual-blockchain asset processing scheme: a physical blockchain managed by regulatory agencies and a digital blockchain managed through smart contracts. Real-world assets managed by the physical blockchain and digital credentials managed by the digital blockchain are dynamically mapped throughout their entire 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, through mapping and synchronization, on the digital blockchain, thus avoiding the risk of fraudulent assets.

[0035] To address the transaction risks inherent in related technologies, this disclosure proposes a dual-track parallel digital model for real-world assets, referred to as the dual-track parallel model. Real-world assets include, for example, real estate, commodities, bonds, stocks, artwork, and intellectual property.

[0036] Figure 2 A schematic diagram of a blockchain-based asset processing system with a dual-track parallel model, representing some embodiments of this disclosure, is shown.

[0037] like Figure 2 As shown, the asset processing system includes: a physical space blockchain, managed by regulatory agencies; and a digital space blockchain, managed through smart contracts. Real-world assets managed by the physical space blockchain and digital credentials managed by the digital space blockchain are dynamically mapped throughout their entire lifecycle. The physical space blockchain and the digital space blockchain perform bidirectional data synchronization based on oracles and dynamic hash consistency constraints. This reduces transaction risks. For example, asset transfers or mortgages, through regulation, are reflected on the physical space blockchain, and then, through mapping and synchronization, are reflected on the digital space blockchain, thereby avoiding the risk of fraudulent assets.

[0038] (1) Dual-track parallel model: The two tracks run in parallel throughout the entire process, which means that the physical space and the digital space are fully connected.

[0039] (2) Dual-track information consistency: The physical space and digital space maintain continuous consistency throughout the entire time and process. Changes in the digital space notify the physical space, and vice versa. The dual-track parallel model integrates digital assets and real-world assets, ensuring full correspondence throughout their entire lifecycle.

[0040] (3) Synchronous: Actions on the dual tracks, whether moving forward or stopping, are synchronized.

[0041] (4) Timely handling: If any space anomaly occurs, all participating nodes on both tracks will be notified at the same time to immediately handle the anomaly.

[0042] (5) Dual-track supervision: The physical space is managed by the regulatory agency, which manages the entire system. At the same time, the regulatory agency can also obtain information notifications from the digital space, and promptly know and control the status of the digital space.

[0043] (6) Highly reliable operation: There are two different blockchain systems to maintain the physical space and the digital space, so as to avoid the collapse of the entire RWA system due to the paralysis of a single system.

[0044] (7) Value protection: The generation or destruction of digital certificates takes place in the digital space, but all real-world assets are in the physical space, not the digital space, thus avoiding asset loss due to problems with the digital system.

[0045] The RWA process in physical space mainly consists of six steps, which are executed and processed by the first, second, third, fourth, fifth, and sixth nodes of the physical space blockchain, respectively. 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.

[0046] Step 1 (Pre-issuance): Select a real-world asset and apply for permission to trade digital assets. In other words, apply for the digitalization of the real-world asset.

[0047] Project teams need to select suitable real-world assets and upload the relevant information to the blockchain (store it in the physical space). After the real-world assets are verified to ensure that they are free from legal disputes, have clear ownership, and are not subject to collateral, a permit is obtained from the relevant authorities to engage in the creation of digital assets, thereby realizing the digital credentialization of real-world assets.

[0048] Step Two (Pre-Issuance): Asset Valuation. The value of real-world assets is objectively and impartially assessed by a third party or online valuation system. The project team needs to provide an asset valuation report for the real-world assets, which is stored on a physical blockchain.

[0049] Step 3 (Pre-issuance): Develop a contract to link real-world assets with digital credentials. This contract is also known as a binding contract.

[0050] The project team and the owner of the real-world asset sign a contract, agreeing that the real-world asset will serve as the underlying asset for the digital certificate. This step is a reliable guarantee that the digital certificate has value.

[0051] Step 4 (Pre-issuance): Develop model information for the digital certificate, including issuance model information and transaction model information.

[0052] Project teams need to develop a model for digital credentials (digital economy), design the share and transaction model of digital credentials based on the total value of contracts and assets, and develop relevant smart contracts according to the model.

[0053] Step 5 (post-issuance): Record the transaction information of digital assets.

[0054] Step 6 (Post-issuance): Automatically report transaction data to regulatory agencies.

[0055] Table 1 below illustrates the RWA physical space flow.

[0056] Table 1 RWA Physical Space Flow

[0057] The RWA process in the digital space mainly consists of six steps, which are executed and processed by the first, second, third, fourth, fifth, and sixth nodes of the digital space blockchain, respectively. 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.

[0058] Step 1 (Pre-issuance): Digital Space Blockchain stores asset information and licensing information for real-world assets.

[0059] 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 project parties on a blockchain system (digital space blockchain) to ensure the authenticity and credibility of asset information.

[0060] Step 2 (Pre-issuance): Digital space blockchain stores asset valuation information (asset valuation report) of real-world assets.

[0061] Digital asset trading platforms record third-party asset valuation reports, or they can provide online asset valuations and record the asset valuation information in the digital space blockchain.

[0062] Step 3 (Pre-issuance): The digital space blockchain stores the binding information (binding contract) between real-world assets and digital certificates, which serves as the basis for issuing digital certificates.

[0063] Digital asset trading platforms store binding contracts that combine real-world assets with digital certificates on the digital blockchain, serving as the legal basis for issuing digital certificates and ensuring the contracts are open and transparent.

[0064] Step 4 (Pre-Issuance): The digital space blockchain stores the model information of the digital certificate and its corresponding smart contracts. This includes, for example, issuance model information and transaction model information, as well as the corresponding smart contracts. For details, please refer to the relevant description of Step 4 in the physical space by RWA, which will not be repeated here.

[0065] Step 5 (Post-issuance): The digital asset platform executes the issuance and trading of digital assets. Relevant information is recorded in the digital space blockchain, which can be synchronized to the physical space blockchain, enabling relevant institutions or customers to find relevant information in the physical space through the platform or blockchain system.

[0066] Step 6 (Post-issuance): The digital asset platform regulates the trading of digital certificates, such as verifying customer identities, ensuring their authenticity and legality, preventing illegal funds from being "legalized" through the financial system, and recording relevant data on the digital space blockchain. The digital space blockchain can be synchronized to the physical space blockchain, so that relevant institutions or customers can find relevant information in the physical space through the platform or blockchain system.

[0067] Table 2 below illustrates the RWA digital space process.

[0068] Table 2 RWA Digital Space Process

[0069] The RWA physical space process and the RWA digital space process are described in comparison with Table 3 below.

[0070] Table 3 Comparison of RWA physical space flow and RWA digital space flow

[0071] Based on the preceding descriptions of the RWA physical space process and the RWA digital space process and their comparison, the dual blockchains in a blockchain-based asset processing system (a blockchain system for asset processing) can be configured as follows.

[0072] 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; issuance is the issuance of digital certificates; wherein, the physical space blockchain takes the lead in mapping the pre-issuance nodes of the physical space blockchain to the pre-issuance nodes of the digital space blockchain; and the digital space blockchain takes the lead in mapping the post-issuance nodes of the physical space blockchain to the post-issuance nodes of the digital space blockchain.

[0073] The pre-issuance nodes include at least one of the first node, second node, third node, and fourth node.

[0074] The first node of the physical space blockchain stores the review materials and review results of real-world assets, as well as the licensing information when the review is passed. It maps the information and licensing information of real-world assets to the first node of the digital space blockchain, which in turn stores the information and licensing information of real-world assets.

[0075] The second node of the physical space blockchain stores the asset valuation information of real-world assets, and maps the asset valuation information of real-world assets to the second node of the digital space blockchain. The second node of the digital space blockchain stores the asset valuation information of real-world assets.

[0076] The third node of the physical space blockchain binds real-world assets and digital certificates, mapping the binding information to the third node of the digital space blockchain. The third node of the digital space blockchain stores the binding information between real-world assets and digital certificates, serving as the basis for issuing digital certificates.

[0077] The fourth node of the physical space blockchain stores the model information of the defined 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 digital certificates.

[0078] The post-issuance node includes at least one of the fifth node and the sixth node.

[0079] The fifth node of the digital space blockchain conducts transactions of digital certificates, records transaction information, maps the transaction information to the fifth node of the physical space blockchain, and stores the transaction information of digital certificates.

[0080] The sixth node of the digital space blockchain supervises digital certificate transactions, records regulatory information, maps the regulatory information to the sixth node of the physical space blockchain, stores the regulatory information of digital certificate transactions, and reports it to regulatory agencies.

[0081] Figure 3 This diagram illustrates an asset processing flow prior to the issuance of digital certificates, as described in some embodiments of this disclosure. Initiating the digitalization of a real-world asset involves the following steps.

[0082] In step 301, select real-world assets, apply for a license to trade digital assets, and submit the relevant materials.

[0083] In step 302, the relevant departments review the materials and upload the materials and review results to the blockchain system (first uploaded to the physical space blockchain, and then synchronized to the digital space blockchain).

[0084] Determine whether all materials have been approved. If not, you can resubmit the materials and reapply, i.e., start from step 301 again. If all materials have been approved, you can continue to step 303.

[0085] In step 303, the asset value and price are assessed.

[0086] For example, asset value and price can be assessed by a third party or online.

[0087] The assessment is judged to be reasonable or not, and thus deemed unacceptable. For example, if the price deviates significantly from the value, the assessment is deemed unreasonable. If the assessment fails, step 303 is repeated; if the assessment passes, step 304 is executed.

[0088] In step 304, a contract is created to link real-world assets with digital credentials.

[0089] In step 305, the model information for the digital certificate is formulated, including, for example, issuance model information and transaction model information.

[0090] Determine whether the system integration test has passed. If the test has failed, adjust the model or modify the smart contract. If the test has passed, digital certificates can be issued (step 306).

[0091] Figure 4 This diagram illustrates the asset processing flow after the issuance of digital certificates, according to some embodiments of this disclosure. The following steps can be performed after the issuance of digital certificates for real-world assets.

[0092] In step 401, digital assets (digital certificates) are traded and circulated online.

[0093] In step 402, digital asset transaction information is recorded.

[0094] In step 403, digital asset transaction information is automatically reported to the regulatory agency.

[0095] In step 404, the regulatory agency checks whether the digital asset transactions are compliant.

[0096] In step 405, if compliant, 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).

[0097] In step 406, if non-compliance is found, the circulation of digital credentials is stopped.
