Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Example one
Fig. 1 is a flowchart of an asset tracing method based on a blockchain according to an embodiment of the present disclosure. The embodiment of the application can be applied to the situation that in the trade financing process, the associated information of the assets in each trade financing stage is determined and is subjected to uplink storage. The method can be executed by an asset tracing device based on a block chain, which can be implemented by software and/or hardware, and is specifically configured in an electronic device carrying a block chain node, where the electronic device can be a mobile terminal or a fixed terminal.
Referring to fig. 1, an asset tracing method based on a block chain according to an embodiment of the present application includes:
s110, receiving an asset interest transfer request initiated by a transaction requester at a target interest transfer stage of a target asset.
The trading requesting party is at least one trading party participating in different business stages of asset increment, asset warehousing, asset pledge, asset ex-warehouse and the like in the trading financing process.
The target assets refer to assets to be circulated or processed and can be determined according to the asset identification. Wherein the type of the target asset may be a property or a real property.
Alternatively, the asset identifier is used to distinguish different target assets, and may be, for example, a Radio Frequency Identification (RFID) tag set in the target asset itself.
It can be understood that by arranging the RFID tag on the target asset, it can be ensured that the target asset information is difficult to copy, copy or recycle, etc., which helps the target asset to establish a unique identity, and by arranging the RFID tag, the basic information of the target asset can be easily read.
The target interest transfer stage means that in the trade financing process of the target asset, the interest property of each transaction participant to the target asset is changed in different stages. By defining a certain stage of trade financing, the interest attributes that each transaction participant enjoys on the target asset can also be determined.
Optionally, the target interest circulation stage includes at least one of an asset newly-adding stage, an asset warehousing stage, an asset financing stage, an asset pledge stage, an asset quality degradation stage, an asset ex-warehousing stage, and the like. It is understood that, as the target asset type is different (such as movable property or real property), the target interest transfer stage corresponding to the target asset is different. For example, for real estate trade financing, the target equity flow phase would not include the asset warehousing phase and the asset ex-warehousing phase.
The asset interest transfer request refers to a request for updating the interest property of the target asset initiated by the transaction requester according to the target interest transfer stage of the transaction requester. For example, a transaction requester is enterprise a, and after enterprise a purchases a specific asset, enterprise a will have ownership of the asset, and at this time, enterprise a may initiate a rights and interests transfer request to bind its ownership rights and interests with the asset.
It can be understood that, by receiving the asset interest transfer request initiated by the transaction requester in the transaction process, the purpose of making the right attribute enjoyed by the target asset by each transaction participant in the target interest transfer stage can be achieved.
And S120, responding to the asset interest transfer request, determining the asset associated information of the target asset, and uplink-storing the asset associated information.
Optionally, the asset association information includes at least one of asset ownership information, transaction participant, asset basic information, and asset status information.
Wherein, the right information refers to the right attribute of each transaction participant to the assets. Typically, the equity attributes include, but are not limited to, ownership, viewing rights, custody rights, pledge administrative rights, and discharge rights, among others.
Transaction participants refer to transaction-related parties involved in trade financing.
Optionally, the transaction participants include at least one of enterprise parties, warehouse parties, financial institutions, and the like. Wherein the financial institution may be a bank.
It will be appreciated that, in conducting an asset equity transfer for a target asset, the parties involved in the trade financing transaction will vary as the target asset is subjected to different stages of the asset equity transfer.
Alternatively, in order to view the target assets stored in the warehouse at any time and any place during the various business phases of trade financing. The warehouse where the target assets are stored is provided with an Internet of things camera, and the transaction participants can check the storage information of the target assets in real time in a remote wireless monitoring mode.
The storage information of the target asset refers to whether the target asset is a real asset in the trade financing transaction process, such as whether the category, specification, quantity, and the like of the target asset are correct. For example, when a financial institution receives an asset financing application initiated by a certain enterprise party, the real storage condition of the target asset stored in the warehouse can be checked through the internet of things camera, so as to verify the accuracy of the storage information of the target asset provided by the enterprise party.
It can be understood that the internet of things camera is arranged in the warehouse for storing the target assets, so that the effect of effectively mastering the real storage information of the target assets even in a non-asset storage site is achieved.
The asset basic information refers to information that gives a detailed description of the asset itself. Generally, the asset basic information includes at least one of a name, a specification model, a quantity, a usage, and the like.
The asset state information refers to whether the target asset is in an available state or a frozen state, and is used for distinguishing the circulation situation of the target asset. It will be appreciated that in the event that the target asset is in a frozen state, the financing transaction for the target asset will not be possible.
The uplink storage means that asset associated information of a target asset is stored on a block chain, and the characteristic of decentralization of the block chain is utilized to ensure that the information cannot be tampered and the source can be traced.
Specifically, the asset association information of the target asset refers to binding the contact relationship established between the transaction requester and the target asset aiming at the asset interest transfer request initiated by the transaction requester in the target interest transfer stage, and is embodied in the asset association information of the target asset.
It can be understood that, recording the asset associated information of the target asset on the blockchain can effectively prevent the asset associated information from being tampered.
According to the method and the device, the asset interest transfer request initiated by the transaction requester at the target interest transfer stage of the target asset is received, the asset associated information of the target asset is determined after the asset interest transfer request is responded, and the asset associated information is linked and stored, so that when the interest transfer occurs to the target asset, the asset associated information can be recorded on a block chain by using a block chain technology, the information cannot be tampered, and the validity and the accuracy of the information stored on the chain are guaranteed.

And S230, uplink storage is carried out on the asset association information comprising the asset ownership information.
Specifically, asset association information including information of a name of the enterprise side, a start-stop time of ownership that the enterprise side has with respect to the target asset, and the like is generated and the asset association information is uplink-stored.
The property ownership information of the target property at the property adding stage is determined and is subjected to chain link storage, and the property association information at the property adding stage is effectively guaranteed to be not falsified by utilizing the characteristic of block chain decentralization, so that the change process of the target property association information can be traced conveniently.
In this embodiment, the asset interest transfer request is initiated by the enterprise. It is to be understood that the asset interest transfer request may also be initiated by any one of the warehouse side and the financial institution, and this is not specifically limited in this embodiment of the present application.

Optionally, before responding to the asset warehousing request, the method further comprises: and if the asset warehousing request comprises the approval passing identification of the warehouse side, triggering response operation on the asset warehousing request. The approval passing identifier of the warehouse side can be an allowable identifier allowing the enterprise side to store the target asset in the warehouse of the warehouse side, or a default passing identifier when the approval passing identifier is not added. The approval pass identifier may be a paper contract or an electronic contract.
It can be understood that, in the asset warehousing stage, if the approval pass identifier of the warehouse party for the target asset is not obtained, the response operation to the asset warehousing request will not be triggered, and the accuracy of determining the asset right attribute is effectively ensured by checking the approval pass identifier of the warehouse party.
Accordingly, the enterprise side may involve the operation of bringing the assets out of the warehouse after the assets are put into the warehouse. Optionally, receiving an asset ex-warehouse request initiated by an enterprise side to the warehouse side for the target asset; in response to the asset ex-warehouse request, generating asset ownership information as follows: the enterprise side possesses ownership of the target asset and uplinks asset association information including the asset ownership information. Wherein the asset ex-warehouse request occurs in the asset ex-warehouse stage.
It can be understood that by determining the asset ownership information of the target asset at the asset ex-warehouse stage and performing uplink storage on the asset ownership information, the asset associated information at the asset ex-warehouse stage is effectively guaranteed to be not falsifiable by using the characteristic of block chain decentralization, and the tracing of the change process of the target asset associated information is facilitated.
Optionally, before responding to the asset ex-warehouse request, the method further comprises: and if the asset ex-warehouse request comprises the approval pass identification of the warehouse side, triggering response operation to the asset ex-warehouse request. The approval pass identification of the warehouse side refers to an allowed identification that the enterprise side can transfer the target asset from the warehouse of the warehouse side. The approval pass identifier may be a paper contract or an electronic contract.
It can be understood that, in the stage of asset ex-warehouse, if the approval pass identifier of the warehouse side for the target asset is not obtained, the response operation to the asset ex-warehouse request will not be triggered, and the accuracy of determining the asset interest attribute is effectively ensured by checking the approval pass identifier of the warehouse side.
When the enterprise side has trade financing requirements, the assets stored in the warehouse can be selected to be financed. Optionally, receiving an asset financing request initiated by an enterprise party to the financial institution for a target asset; in response to the asset financing request, generating asset ownership information as follows: the enterprise side possesses ownership of the target asset, and determines that the warehouse side possesses custody of the target asset, and uplinks asset association information including the asset ownership information. Wherein the asset financing request occurs during an asset financing phase.
Alternatively, after the asset financing request passes, the target asset, as the asset undergoing trade financing, will be frozen and deposited in the warehouse with the target asset in an unavailable or non-tradable state. Therefore, if the asset association information may further include asset status information, an asset financing request initiated by the enterprise to the financial institution for the target asset needs to be received; in response to the asset financing request, generating asset status information as follows: and adjusting the asset state information of the target asset to be in a frozen state, and uplink-storing the asset association information comprising the asset state information.
It can be understood that by defining asset ownership information and asset state information of a target asset in the asset financing stage and performing uplink storage on the asset ownership information and the asset state information, the asset associated information in the asset financing stage is effectively guaranteed to be not falsifiable by using the characteristic of decentralized block chaining, and the target asset associated information change process is conveniently traced.
Optionally, prior to responding to the asset financing request, the method further comprises: and if the asset financing request comprises an approval pass identifier of the financial institution, triggering response operation to the asset financing request. The approval passing identification of the financial institution refers to an allowable identification that the financing application initiated by the enterprise to the financial institution is approved by the financial institution. The approval pass identifier may be a paper contract or an electronic contract.
It can be understood that, in the asset financing stage, if the approval pass identifier of the financial institution for the target asset is not obtained, the response operation to the asset financing request will not be triggered, and the accuracy of determining the asset interest attribute is effectively ensured by checking the approval pass identifier of the financial institution.
After the warehouse side applies for financing through the financial institution, the enterprise side needs to mortgage the assets for financing. Optionally, receiving a property pledge request initiated by an enterprise party to the financial institution for the target property; in response to the asset pledge request, generating asset ownership information as follows: the enterprise side has the view right of the target asset, the warehouse side has the custody right of the target asset, and the financial institution has the pledge right and ownership right of the target asset and stores the asset association information comprising the asset ownership information in an uplink manner. Wherein the asset pledge request occurs during the asset pledge stage. It is understood that, during the asset pledge stage, the enterprise side needs to store the target asset (e.g., the target asset is a moving asset) in a warehouse designated or approved by the financial institution, and at this time, the warehouse side needs to change, that is, the right to keep the target asset is transferred to the designated warehouse side.
In this embodiment, in the asset pledge stage, if the pledge occurs, the pledge monitoring right of the pledge to the target asset is also determined. Alternatively, if the enterprise party is unable to fulfill the financing obligation, the financial institution may have the authority to alternate the asset, at which point the financial institution may have a qualification right for the target asset.
It can be understood that by determining the asset ownership information of the target asset in the asset pledge stage and performing uplink storage on the asset ownership information, the asset association information in the asset pledge stage is effectively guaranteed to be not falsified by using the characteristic of block chain decentralization, and the tracing of the change process of the target asset association information is facilitated.

After the enterprise side makes a timely payment, a quality assessment application for the asset may be initiated to the financial institution to regain ownership of the target asset. Optionally, receiving an asset qualification request initiated by an enterprise party to the financial institution for the target asset; in response to the asset qualification request, generating asset ownership information as follows: the enterprise side possesses ownership of the target asset, the warehouse side possesses custody of the target asset, and the asset association information including the asset ownership information is stored in an uplink. Wherein the asset degradation request occurs during an asset degradation phase.
Optionally, after the assets are demoted, the target asset will no longer be in an unavailable or non-tradable state, at which point the target asset may again be traded financed. Therefore, if the asset association information further includes asset status information, an asset quality assessment request issued by the enterprise to the financial institution for the target asset needs to be received; in response to the asset qualification request, the following asset status information: and adjusting the asset state information of the target asset to be in an available state, and uplink-storing the asset association information comprising the asset state information.
It can be understood that by defining asset ownership information and asset state information of a target asset in an asset degradation stage and performing uplink storage on the asset ownership information and the asset state information, the asset ownership information and the asset state information are effectively guaranteed to be not falsifiable in the asset degradation stage by using the characteristic of decentralized block chaining, and the change process of the target asset associated information is conveniently traced.
Optionally, prior to responding to the asset qualification request, the method further comprises: and if the asset quality assessment request comprises the approval pass identification of the financial institution, triggering response operation to the asset quality assessment request. Here, the approval pass identifier of the financial institution means an identifier that the financial institution releases the mortgage on the target asset and returns the ownership of the target asset to the enterprise. The approval pass identifier may be a paper contract or an electronic contract.
It can be understood that, in the asset qualification stage, if the approval pass identifier of the financial institution for the target asset is not obtained, the response operation to the asset qualification request will not be triggered, and the accuracy of determining the asset right attribute is effectively ensured by checking the approval pass identifier of the financial institution. Optionally, in response to an asset query request initiated based on an asset identification of an asset to be queried, querying asset association information of the asset to be queried.
Specifically, when an asset query requirement exists in each transaction participant, an asset query request is initiated based on an asset identifier of an asset to be queried; and according to the asset identification in the asset query request, searching for asset associated information corresponding to the asset identification in the stored at least one asset information.
It can be understood that, in the process of participating in trade financing, each transaction participant inquires about the asset associated information, including inquiring whether the asset is in an available state or not and inquiring about the rights and interests attribute condition of each transaction participant to the asset, so that the problem that each transaction participant cannot check the asset associated information in real time in the trade financing process is solved.
Because the transaction data generated in response to the transaction request in the block chain can generate corresponding transaction identifiers through the hash calculation and other manners, at least one transaction participant can also query the corresponding transaction data through the acquired transaction identifiers. The transaction data comprises asset associated information corresponding to at least one target interest circulation stage.
Optionally, in response to an asset verification request initiated based on an asset identification of an asset to be verified, verifying asset association information of the asset to be verified.
Specifically, when an asset verification requirement exists, a transaction party initiates an asset verification request based on an asset identifier of an asset to be verified; according to the asset identification in the asset verification request, searching asset associated information corresponding to the asset identification in the stored at least one asset information; and verifying the asset information provided by other transaction parties according to the inquired asset association information so as to confirm the authenticity of the asset information provided by the transaction parties.
For example, when an enterprise sends a pledge for trade financing to a financial institution, the financial institution may search for associated information of an asset according to an asset identifier and the asset information provided by the enterprise according to the asset information provided by the enterprise, and compare the associated information with the asset information provided by the enterprise to verify the authenticity of the asset information provided by the enterprise (e.g., verify whether the ownership of the asset belongs to the enterprise).
The asset associated information in the embodiment of the application comprises asset ownership information, and the feasibility of tampering the asset associated information is effectively prevented by determining the ownership attribute of each transaction participant in each interest transfer stage of the asset and using the determined asset ownership information as a part of the asset associated information for uplink storage; meanwhile, the asset query request and the verification request initiated based on the asset identification of the asset to be queried are provided for querying and verifying the asset associated information, the asset information is checked by each transaction participant in real time through the query operation, and the information of each transaction participant is mutually checked through the verification operation, so that the authenticity of the information of the transaction participants is verified.
