[0017] Figure 6 This is a transformation diagram of the digital asset transfer table described in this application. Detailed Implementation

[0018] Figure 1 The diagram below illustrates the entity connection network of this application. In a blockchain network, there are multiple nodes. Due to the decentralized and immutable nature of blockchain, different nodes can communicate with each other. Users establish connections with the blockchain network through a platform. It should be noted that the platform includes at least one processor, which is used to process information from users and to implement data connections between users and the blockchain network.

[0019] See Figure 2 , Figure 2As shown in the application scenario diagram of this application, the user's requesting end sends a digital asset conversion request to the platform. The platform receives the user's digital asset conversion request through a processor and verifies the digital asset transfer table through the processor. It then obtains the digital asset information table corresponding to the digital asset transfer table from the blockchain network. The digital asset information table includes asset content information, asset address information, and asset identification number, and the asset identification number is unique. After transferring the asset to the user's requesting end, invalid digital asset data packets are stored on the blockchain.

[0020] See Figure 3 , Figure 3 This is a data flow diagram showing how multiple processors in the platform described in this application process the digital asset conversion request. It should be noted that there can be multiple processors or just one, and the number of processors can be adjusted in real time according to the actual situation of the platform. In one embodiment of this application, processor 1 is connected to the requesting end where the user is located and is used to receive digital asset conversion requests from the requesting end.

[0021] Figure 4 This is a data flow diagram of a method for converting digital assets into physical assets according to this application;

[0022] See Figure 5 The method described in this application includes the following steps:

[0023] S100: A digital asset conversion request is received from the requesting end by at least one processor;

[0024] The digital asset conversion request is received from a first computing device, which is operated by a first institution associated with the requesting end. The digital asset conversion request includes a digital asset transfer table, which is used to record the ownership change information of the digital asset signal package, and only the current owner has the right to change the ownership of the digital asset transfer table.

[0025] S200: The digital asset transfer table is verified by at least one processor;

[0026] In one embodiment of this application, the digital asset transfer table is obtained, and it is determined whether the owner of the digital asset data packet recorded in the digital asset transfer table is consistent with the requesting party. If they are consistent, the verification passes; otherwise, the verification fails. The digital asset transfer table records the owner information of the digital asset data packet. By judging the digital asset transfer table, economic losses can be avoided due to conversion operations of digital assets by persons other than the owners of the digital assets.

[0027] S300: If the verification is successful, at least one processor obtains the digital asset information table corresponding to the digital asset transfer table. The digital asset information table includes asset content information, asset address information, and asset identification number. The asset identification number is unique.

[0028] S400: At least one processor transfers assets to the requesting client according to the digital asset information table;

[0029] S500: At least one processor invalidates the digital asset transfer table and the corresponding digital asset information table;

[0030] S600: At least one processor generates an invalid digital asset data packet based on the digital asset transfer table and the corresponding digital asset information table, and stores it on the blockchain.

[0031] See Figure 6 , Figure 6 The transformation diagram of the digital asset transfer table in the digital asset conversion method is reflected. After the digital asset transfer table held by the user's requesting end is sent to the processor, the processor obtains the corresponding digital asset information table from the blockchain, transfers the assets corresponding to the digital asset transfer table to the requesting end, changes the digital asset transfer table to invalid, generates an invalid digital asset data packet, and sends it to the requesting end and stores it on the blockchain.

[0032] In one embodiment of this application, verifying the digital asset transfer table specifically includes the following steps:

[0033] Obtain the aforementioned digital asset transfer table;

[0034] Determine whether the owner of the digital asset data packet recorded in the digital asset transfer table is consistent with the requesting party;

[0035] If they match, the verification passes.

[0036] If they do not match, the verification fails.

[0037] In one embodiment of this application, the step of transferring assets to the requesting party according to the digital asset information table includes the following steps:

[0038] Send asset transfer information to the warehouse based on the digital asset information table;

[0039] The warehousing end transfers the assets to the requesting end based on the asset transfer information;

[0040] Send asset confirmation information to the requesting party;

[0041] If the requesting party confirms the asset confirmation information, the asset transfer to the requesting party is completed.

[0042] In one embodiment of this application, before receiving the digital asset conversion request from the requesting end, the following steps are further included:

[0043] Obtain a digital asset generation request from the requesting end, the digital asset generation request containing asset storage information;

[0044] The requesting party is the current owner of the digital asset, possessing ownership of the digital asset. They can process the digital asset transfer table to complete operations such as transfer, gifting, and conversion. It should be noted that once the ownership changes, only the current owner of the digital asset has the right to process the digital asset and change the owner in the digital asset transfer table.

[0045] Verify the asset storage information;

[0046] If the verification is successful, a digital asset is generated according to the digital asset generation request. The digital asset includes a digital asset information table and a digital asset transfer table corresponding to the digital asset information table. The digital asset information table includes asset content information, asset address information, and asset identification number. The asset identification number is unique. The digital asset transfer table is used to record the change information of the owner of the digital asset signal package, and only the current owner has the right to change the owner of the digital asset transfer table.

[0047] The digital asset data package includes a digital asset information table and a digital asset transfer table corresponding to the digital asset information table. The digital asset information table includes asset content information, asset address information, and asset identification number. The asset identification number is unique. The digital asset transfer table is used to record the change information of the ownership of the digital asset data package, and only the current owner has the authority to change the ownership of the digital asset transfer table.

[0048] The asset content information includes the asset type, quantity, and all information that accurately describes the asset. Asset address information records the asset's location. If the asset is stored in a trusted third-party warehouse, the asset address information records the storage location. If the asset is an intangible asset, the asset address information is the storage location of the intangible asset; in this case, the asset address information can be a URL or any remote server connected to the blockchain network.

[0049] Send the digital asset transfer table to the requesting end;

[0050] The digital assets are stored on the blockchain.

[0051] In one embodiment of this application, before obtaining the digital asset generation request from the requesting end, the method further includes the following steps:

[0052] The requesting party stores the assets at the warehousing end;

[0053] In one embodiment of this application, the warehousing terminal is a trusted third-party warehousing terminal. For example, when the asset is a bulk commodity, the requesting party stores the bulk commodity at the warehousing terminal.

[0054] The warehousing terminal generates asset storage information based on the asset, and the asset storage information includes asset content information, asset address information, and asset owner identity information.

[0055] More specifically, for example, when the asset is a bulk commodity, the warehousing end generates asset storage information based on the asset type, asset quantity, asset storage time, and the identity of the asset owner.

[0056] The warehousing end sends the asset storage information to the requesting end.

[0057] More specifically, the asset owner can use the asset storage information to transfer assets at the warehousing facility. In one embodiment of this application, verifying the asset storage information includes the following steps:

[0058] Send asset verification information to the warehouse terminal;

[0059] Determine whether the warehouse terminal confirms the asset verification information;

[0060] If the warehouse confirms the asset verification information, the verification is successful.

[0061] If the warehouse does not confirm the asset verification information, the verification will fail.
