[0069] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0070] Figure 1 : is a schematic diagram of the main process of a data processing method using a blockchain enterprise wallet according to the first embodiment of the present invention, such as Figure 1 As shown, including:

[0071] Step S101: receiving a business processing request, and obtaining digital asset transaction data according to the business processing request;

[0072] Step S102: determining the target document type to be generated and the corresponding enterprise wallet sub-account according to the digital asset transaction data; retrieving a template library, determining therefrom a document template corresponding to the document type and determining a document review process corresponding to the enterprise wallet sub-account;

[0073] Step S103: Generate a target document based on the digital asset transaction data according to the document template, and review the target document according to the document review process, so as to submit the digital asset transaction data corresponding to the target document to the blockchain network after the review is passed.

[0074] The method of the present invention can support enterprises to use blockchain wallets to implement the operation of first-level order preparation and multi-level review based on digital asset transaction data according to a customized process, and submit the digital asset transaction data to the blockchain network after the review is passed; it avoids the situation where the digital assets of enterprises are directly operated and submitted without review, which is in line with the current habit of enterprises operating bank public deposit accounts and reduces operational risks.

[0075] In some embodiments, the enterprise wallet sub-account is a sub-account of an enterprise wallet device deployed on a blockchain network; wherein the private key information of the enterprise wallet device is stored in multiple copies on the server in the form of a server-managed key.

[0076] The wallet private key is hosted by multiple copies of the server, which can avoid the loss of digital assets caused by the loss of the key.

[0077] In actual applications, the server-side private key can be stored using a hardware encryption machine. The wallet private key that truly controls the distributed ledger assets can be hosted on the server side, and the existing enterprise authentication methods (such as online banking shield, challenge token) can be used as the enterprise user access identity and mapped with the wallet private key. In turn, when enterprise users operate wallet assets, transactions can carry authentication information (such as: online banking shield signature or challenge token random number) for the server to verify the authentication information, and use the corresponding wallet private key to construct blockchain transactions and operate on-chain assets.

[0078] In some embodiments, determining the target document type to be generated and the corresponding enterprise wallet sub-account according to the digital asset transaction data includes:

[0079] Determine the target document type according to the business attributes in the digital asset transaction data;

[0080] And according to the digital asset attributes in the digital asset transaction data, determine the enterprise wallet sub-account corresponding to the digital asset from the enterprise wallet account.

[0081] Furthermore, in some embodiments, determining the corresponding enterprise wallet sub-account according to the digital asset attributes in the digital asset transaction data includes:

[0082] Based on the currency type and / or transaction amount value in the digital asset attributes, the enterprise wallet sub-account corresponding to the digital asset is determined according to a preconfigured transaction account correspondence table.

[0083] The document type corresponding to the business scenario (such as purchase, sale, etc.) can be determined, and then the corresponding document template can be called in the subsequent steps to fill in the digital asset transaction data into a document template with a certain format to generate the target document.

[0084] Digital assets may have attributes such as currency type and / or transaction amount value. For example, different enterprise wallet sub-accounts may be used when conducting transactions in different currencies. Different enterprise wallet sub-accounts may also be used for transaction amounts in different ranges in transaction data. In some practical applications, different enterprise wallet sub-accounts may also be set up according to different transaction regions and transaction objects, so as to facilitate management, query and tracking.

[0085] In some embodiments, calling the template library, determining the document template corresponding to the document type and determining the document review process corresponding to the enterprise wallet sub-account therefrom, includes: calling the document template library and the process template library in the template library; determining the document template corresponding to the document type from the document template library; and, determining the document review process corresponding to the enterprise wallet sub-account from the process template library.

[0086] Furthermore, in some embodiments, generating a target document based on the digital asset transaction data according to the document template, and reviewing the target document according to the document review process includes:

[0087] Selecting one of the generation nodes indicated by the document template as the generation node of the target document; at the document generation node, generating the target document using the document template based on the digital asset transaction data;

[0088] The audit node of the target document is determined according to the document audit process, so that the target document is sent to the audit node, and then the target document is audited at the audit node.

[0089] A workflow engine can be introduced and configured by the enterprise manager; different process templates can be set for each enterprise wallet sub-account, and different operation permission functions can be set for different nodes (operators) in the enterprise, such as document generation operations and different levels of review operations.

[0090] Among them, the generation node of the document can be specified in the document template, and in other practical applications, it can also be specified in the document review process. Different processes can be set for different corporate wallet sub-accounts, and the review nodes can be set specifically: such as the number of reviews, review node levels, etc. The specific review content can be: the authenticity of the transaction, transaction scenario information, transaction voucher information (e.g.: for customs declarations, you can review its voucher information, such as shipping bills).

[0091] Through the above method, a one-level document preparation and multi-level review model is realized, which avoids the situation where corporate digital assets are directly operated and submitted without review. It is in line with the current corporate habits of operating bank public deposit accounts and reduces operational risks.

[0092] In some embodiments, after the audit node audits the target document, it also includes: if the audit fails, generating a document to be updated based on the failed data determined by the audit node; returning the document to be refilled to the document generation node to update the document to be updated.

[0093] In some practical applications, the failure information and the update process (such as the node performing the update operation, the specific content of the update operation, and the update time information) may also be recorded.

[0094] In some embodiments, after submitting the digital asset transaction data corresponding to the target document to the blockchain network, the process further includes:

[0095] The enterprise wallet sub-account is updated according to the digital asset transaction data.

[0097] The document maker fills in the digital asset transaction information and performs document making operations. The reviewer reviews the transaction. After the reviewer successfully reviews the transaction, the transaction will be submitted to the blockchain network, triggering a real asset transaction. In addition, before the reviewer reviews the document, the document maker is supported to recycle or delete the document. The recycled unit can be modified and resubmitted. When the reviewer reviews the document, if the approval is rejected, the document can be directly returned to the document maker.

[0098] In some embodiments, after submitting the digital asset transaction data corresponding to the target document to the blockchain network, the process further includes:

[0099] Call the declaration interface to obtain the declaration template;

[0100] Generate a declaration document using the declaration template based on the digital asset transaction data;

[0101] The declaration document is sent to the corresponding declaration system through the declaration interface to realize transaction declaration.

[0102] In specific applications, the declaration interface can be the external interface of the institutions related to trade declaration business stipulated by the state. It can support binding multiple international balance of payments declaration information for one digital asset transaction (the declaration types may be different). Among them, the international balance of payments declaration information may include: international balance of payments code, nature of remittance, nature of trade, declarant and other information.

[0103] Through the above method, enterprises can automatically submit international balance of payments declaration information by calling the declaration interface during the process of using digital asset transactions in cross-border trade, thereby ensuring the regulatory compliance of transactions.
