Detailed Description
The present invention will be described in detail with reference to the following embodiments in order to fully understand the objects, features and effects of the invention, but the present invention is not limited thereto.
Fig. 1 is a block diagram illustrating a block chain-based file transaction system according to an embodiment of the present invention. As shown in fig. 1, the system includes: owner unit 101, blockchain platform 102, monitoring unit 103, transaction user unit 104, and transaction execution unit 105.
The owner unit 101 is connected to the blockchain platform 102 for sending the first file to the blockchain platform 102.
The system can be applied to the trading in the intellectual property fields of patent rights, trademark rights, copyright rights and the like. In order to be able to clearly distinguish between the file sent by the owner unit 101 and the file sent by the trade user unit 104 in the following, in the present invention the file sent by the owner unit 101 is referred to as the first file and the file sent by the trade user unit 104 is referred to as the second file. Wherein the first file includes: a first rights identification file, a first identity information file, a first target file and a first transaction type file; the second file includes: a second rights identification file, a second identity information file, a second target file, and a second transaction type file. The first file and the second file can also be set by those skilled in the art according to actual needs, and are not limited herein.
Specifically, the first subject file and the second subject file respectively refer to a file for performing a transaction sent by the owner unit 101 and a file for performing a transaction sent by the transaction user unit 104, the first right certification file and the second right certification file respectively refer to a file for certifying right information of the first subject file and a file for certifying right information of the second subject file, the first transaction type file and the second transaction type file respectively refer to a file for indicating a transaction type supported by the first file and a file for indicating a transaction type supported by the second file, the first identity information file and the second identity information file respectively refer to a file for indicating identity information of a provider of the first file (i.e., the owner unit 101) and a file for indicating identity information of a provider of the second file (i.e., the transaction user unit 104), specifically, the first identity information file and the second identity information file may include an identity label and the like. Taking the system applied to the field of proprietary transaction as an example, the first target file is an authorized patent file sent by the owner unit 101 for performing transaction, the first right certification file is a file for certifying patent right information of the authorized patent file, the first transaction type file describes whether the transaction type supported by the authorized patent file is purchase or permitted, and the like, and the first identity information file indicates that the provider of the first target file, the first right certification file, and the first transaction type file is the owner unit 101.
The blockchain platform 102 is connected to the monitoring unit 103, and configured to generate a first digital currency address corresponding to the first file according to the first file sent by the owner unit 101, and send the first file and the first digital currency address corresponding to the first file to the monitoring unit 103.
In order to facilitate fast and convenient management of the first file and its file transaction, after the blockchain platform 102 receives the first file sent by the owner unit 101, the blockchain platform 102 stores the received first file into the public chain of the blockchain platform 102 to ensure the security of the first file, and generates a first digital currency address corresponding to the first file according to the first file. The specific generation rule for generating the first digital currency address can be set by a person skilled in the art according to actual needs, and is not limited herein.
The monitoring unit 103 is configured to determine, according to the first file and the first digital currency address corresponding to the first file, file association information corresponding to the first digital currency address, and send the file association information corresponding to the first digital currency address to the blockchain platform 102.
The file association information may include: digital certificates, transaction amount allocation information, and digital currency amounts. Specifically, the monitoring unit 103 is configured to determine a digital certificate corresponding to the first digital currency address according to a first ownership certificate file in a first file corresponding to the first digital currency address; determining transaction amount distribution information corresponding to the first digital currency address according to the first identity information file in the first file corresponding to the first digital currency address; and evaluating value grades of different transaction types corresponding to the first target file in the first file corresponding to the first digital currency address according to the first target file in the first file corresponding to the first digital currency address and the first transaction type file, and determining the digital currency amount corresponding to the first digital currency address according to the value grades.
Assuming that the first target document is an authorized patent document, and it is known from the corresponding first transaction type document that the transaction type supported by the authorized patent document is purchase and authorized, the value grade corresponding to the authorized patent document when the transaction type is purchase is evaluated as grade a, the value grade corresponding to the authorized patent document when the transaction type is authorized is grade B, and different value grades correspond to different digital currency amounts, for example, the digital currency amount corresponding to grade a is 10000, and the digital currency amount corresponding to grade B is 3000. Those skilled in the art can set the value grade and the corresponding relationship between the value grade and the digital currency amount according to actual needs, and the setting is not limited herein.
The trade user unit 104 is connected to the trade execution unit 105, and is configured to send a first file trade request of a trade user to the trade execution unit 105.
The trading user may retrieve and view files in the system through the trading user unit 104. The first file transaction request refers to a file transaction request sent by a transaction user for a first target file. Taking the system applied to the field of proprietary transaction as an example, when a transaction user wants to purchase or be granted a certain authorized patent document provided by the owner unit 101, the transaction user may generate a first document transaction request for the authorized patent document, and send the first document transaction request to the transaction execution unit 105, so that the transaction execution unit 105 sends the first document transaction request to the blockchain platform 102.
The transaction execution unit 105 is connected to the blockchain platform 102, and configured to send the received first file transaction request to the blockchain platform 102.
The blockchain platform 102 is also configured to: generating first file transaction information of different transaction types according to the received file association information corresponding to the first digital currency address sent by the monitoring unit 103; and according to the first file transaction information, judging the received first file transaction request sent by the transaction execution unit 105 to obtain a judgment processing result.
The transaction execution unit 105 is further configured to receive the determination processing result sent by the blockchain platform 102, and complete the first file transaction according to the determination processing result.
In order to quickly process the first file transaction request, the blockchain platform 102 may generate the first file transaction information of different transaction types according to the received file association information corresponding to the first digital currency address sent by the monitoring unit 103 when the first file transaction request is not received, and if the transaction types include purchase and approval, generate the first file transaction information corresponding to the purchase transaction type and generate the first file transaction information corresponding to the approval transaction type.
After the blockchain platform 102 receives the first file transaction request sent by the transaction execution unit 105, the blockchain platform 102 performs judgment processing on the received first file transaction request sent by the transaction execution unit 105 according to the first file transaction information, so as to obtain a judgment processing result. Specifically, the blockchain platform 102 determines whether the first file transaction request conforms to the corresponding first file transaction information; if yes, controlling the transaction execution unit 105 to generate a corresponding intelligent contract; if not, the transaction execution unit 105 is controlled to generate corresponding prompt information. For example, if the transaction type in the first document transaction request is a purchase, then it may be determined whether the amount of digital currency in the first document transaction request exceeds the amount of digital currency in the first document transaction information corresponding to the purchase of the transaction type; if the digital currency amount in the first file transaction request exceeds the digital currency amount in the first file transaction information corresponding to the purchase of the transaction type, the first file transaction request is in accordance with the corresponding first file transaction information; if the digital currency amount in the first file transaction request does not exceed the digital currency amount in the first file transaction information corresponding to the purchase type, the first file transaction request is not in accordance with the corresponding first file transaction information.
Under the condition that the blockchain platform 102 determines that the first file transaction request conforms to the corresponding first file transaction information, the blockchain platform 102 controls the transaction execution unit 105 to generate a corresponding intelligent contract, and then the transaction execution unit 105 can perform transaction processing according to the intelligent contract. Wherein, intelligent contract includes at least: transaction amount, bid mode, and payment mode. Specifically, the transaction amount is an amount required for performing a file transaction, the bid mode is that a transaction user pays by cash, digital currency, shares and the like, and the payment mode is that the transaction user pays by one-time payment or installments payment. When the blockchain platform 102 determines that the first file transaction request does not conform to the corresponding first file transaction information, the blockchain platform 102 controls the transaction execution unit 105 to generate corresponding prompt information, for example, the prompt information may be "the file transaction request does not conform to the file transaction information, and the transaction user requests the transaction user to modify the file transaction request", so that the transaction user may modify information such as the amount of digital money and/or the transaction type in the first file transaction request according to the prompt information.
After the transaction execution unit 105 generates the corresponding intelligent contract, the transaction execution unit 105 may generate a transaction record and send the transaction record to the blockchain platform 102 and the monitoring unit 103 for storage, and may also generate a payment request according to the transaction amount in the intelligent contract, so that the transaction user can pay according to the payment request. The blockchain platform 102 may store the transaction records in a public chain of the blockchain platform 102. The transaction user can pay cash, digital currency (such as bitcoin) or shares, etc. having a value equivalent to the transaction amount in the smart contract according to the payment request.
After the transaction user completes payment, the transaction execution unit 105 allocates the transaction amount to the beneficiary according to the transaction amount allocation information in the first file transaction information in the blockchain platform 102. Wherein, the beneficiary acquirer comprises: one or more of an owner unit 101, a monitoring unit 103, a transaction user unit 104 and a transaction execution unit 105.
In addition, the technical scheme provided by the invention can also enable the target file of the trading user to participate in file trading, so that the trading user obtains benefit distribution. Specifically, the transaction user may send the second file to the transaction execution unit 105 through the transaction user unit 104, in which case the transaction execution unit 105 sends the received second file to the blockchain platform 102. The blockchain platform 102 stores the received second file into a public chain of the blockchain platform 102 to ensure the security of the second file, generates a second digital currency address corresponding to the second file according to the second file, and sends the second file and the second digital currency address corresponding to the second file to the monitoring unit 103; the monitoring unit 103 determines file association information corresponding to the second digital currency address according to the second file and the second digital currency address corresponding to the second file, and sends the file association information corresponding to the second digital currency address to the blockchain platform 102; and the blockchain platform 102 generates second file transaction information of different transaction types according to the received file association information which is sent by the monitoring unit and corresponds to the second digital currency address.
The file association information may include: digital certificates, transaction amount allocation information, and digital currency amounts. Specifically, the monitoring unit 103 is further configured to: determining a digital certificate corresponding to the second digital currency address according to a second ownership certificate in a second file corresponding to the second digital currency address; determining transaction amount distribution information corresponding to the second digital currency address according to a second identity information file in a second file corresponding to the second digital currency address; and evaluating value grades of different transaction types corresponding to the second target file in the second file corresponding to the second digital currency address according to the second target file in the second file corresponding to the second digital currency address and the second transaction type file, and determining the digital currency amount corresponding to the second digital currency address according to the value grades. The specific determination method of the digital certificate corresponding to the second digital currency address, the transaction amount distribution information corresponding to the second digital currency address, and the digital currency amount corresponding to the second digital currency address is the same as the specific determination method of the digital certificate corresponding to the first digital currency address, the transaction amount distribution information corresponding to the first digital currency address, and the digital currency amount corresponding to the first digital currency address, and therefore, the detailed description thereof is omitted here.
The way of generating the second file transaction information is the same as the way of generating the first file transaction information, and is not described herein again.
When a certain transaction user wants to trade (e.g., purchase) a second markup document of another transaction user, the transaction user may transmit a second document trade request of the transaction user to the trade execution unit 105 through the transaction user unit 104. The second file transaction request refers to a file transaction request sent by a transaction user for a second target file. Then, the transaction execution unit 105 sends the received second file transaction request to the blockchain platform 102, the blockchain platform 102 performs judgment processing on the received second file transaction request sent by the transaction execution unit according to the second file transaction information to obtain a judgment processing result, and then the transaction execution unit 105 receives the judgment processing result sent by the blockchain platform 102 and completes the second file transaction according to the judgment processing result.
Specifically, the blockchain platform 102 determines whether the second file transaction request conforms to the corresponding second file transaction information; if yes, controlling the transaction execution unit to generate a corresponding intelligent contract; if not, the transaction execution unit is controlled to generate corresponding prompt information, and the prompt information can be that the file transaction request does not conform to the file transaction information and the transaction user modifies the file transaction request, and then the transaction user can modify the information such as the digital currency amount and/or the transaction type in the second file transaction request according to the prompt information. The manner of determining whether the second file transaction request conforms to the corresponding second file transaction information is the same as the manner of determining whether the first file transaction request conforms to the corresponding first file transaction information, and is not repeated here.
Similarly, after the transaction execution unit 105 generates the corresponding intelligent contract, the transaction execution unit 105 generates a transaction record and sends the transaction record to the blockchain platform 102 and the monitoring unit 103 for storage, and generates a payment request according to the transaction amount in the intelligent contract, so that the transaction user can pay according to the payment request. The blockchain platform 102 may store the transaction records in a public chain of the blockchain platform 102. The transaction user can pay cash, digital currency (such as bitcoin) or shares, etc. having a value equivalent to the transaction amount in the smart contract according to the payment request. After the transaction user completes payment, the transaction execution unit 105 allocates the transaction amount to the beneficiary according to the transaction amount allocation information in the second file transaction information in the blockchain platform 102. Wherein, the beneficiary acquirer comprises: one or more of an owner unit 101, a monitoring unit 103, a transaction user unit 104 and a transaction execution unit 105.
Optionally, to effectively manage file association information, the blockchain platform 102 may be further configured to: distributing corresponding file association information for a first file corresponding to the first digital currency address according to the first digital currency address; and distributing corresponding file association information for the second file corresponding to the second digital currency address according to the second digital currency address.
Optionally, the blockchain platform 102 may further store the file association information, the first file transaction information, and the first file transaction request corresponding to the first digital currency address and the file association information, the second file transaction information, and the second file transaction request corresponding to the second digital currency address in a public chain of the blockchain platform 102, so as to ensure the security and reliability of the information.
In addition, in order to avoid the situation of the digital money such as the inflation of the currency, the monitoring unit 103 may be connected 105 to the transaction execution unit for issuing the digital money with a fixed total number.
The transaction amount distribution information in the first file transaction information in the blockchain platform 102 and the transaction amount distribution information in the second file transaction information in the blockchain platform 102 both include: a first transaction amount distribution mode and a second transaction amount distribution mode; the first transaction amount distribution mode is that X% is returned to the owner unit 101, Y% is returned to the monitoring unit 103, and 1-X% -Y% is returned to the transaction execution unit 105, wherein X% is more than or equal to 0 and less than or equal to 1, and Y% is more than or equal to 0 and less than or equal to 1; the second transaction amount distribution mode is that all transaction amounts are returned to the transaction user unit 104, and the transaction execution unit 105 collects Z% of the transaction amounts as a commission fee, wherein Z% is more than or equal to 0 and less than or equal to 1. Taking the application of the system in the field of proprietary transaction as an example, the principle that the transaction execution unit 105 allocates the transaction amount to the beneficiary according to the transaction amount allocation information in the first file transaction information in the blockchain platform 102 and the transaction amount allocation information in the second file transaction information in the blockchain platform 102 may be as follows:
1. a first subject document (i.e., an authorized patent document) provided by the purchasing or licensing owner unit 101
(1) If the transaction user pays the authorized patent documents provided by the currency purchase owner unit 101 such as cash, digital currency (such as bitcoin) and the like, the transaction amount can be distributed by adopting a first transaction amount distribution mode in the transaction amount distribution information, namely X% of the transaction amount is returned to the owner unit 101, Y% of the transaction amount is returned to the monitoring unit 103, and 1-X% -Y% of the transaction amount is returned to the transaction execution unit 105, wherein X% is more than or equal to 0 and less than or equal to 1, and Y% is more than or equal to 0 and less than or equal to 1. Specifically, X may be 50 and Y is 20, then 50% of the transaction amount is returned to the owner unit 101, 20% of the transaction amount is returned to the monitoring unit 103, and 30% of the transaction amount is returned to the transaction execution unit 105.
(2) If the trading user purchases not the first-subject document supplied in the above-described money or the permitted-owner unit 101 but a share of the company corresponding to the trading user, the monitoring unit 103 first allocates the share in the above-described manner in (1), and then corresponds 30% of the shares to the total number of digital money held by the digital money owner. For example, if 30% corresponds to 1000 shares of stock and the digital currency held by the digital currency owner is 2000 thousands, 2 digital currencies correspond to 1 share. If a digital currency owner holds 9 digital currencies, the currency is divided into 4.5 shares, and a set of digital accounting representing the 4.5 shares is credited to the digital currency owner's digital account. In addition, when a digital money owner wants to sell his digital money, the corresponding stock right is also sold. When the company's shares can be made available, the monitoring unit 103 can make a change to the shares. In this way, the digital currency held by the trading user also enjoys the equity of shares.
2. If the second subject document (i.e., the authorized patent document) provided by the transaction user unit 104 is purchased or authorized, the transaction amount may be allocated in the second transaction amount allocation manner in the transaction amount allocation information, for example, the entire transaction amount may be owned by the transaction user unit 104 owning the authorized patent document, and the transaction execution unit 105 charges 1% of the transaction amount as a commission.
3. If the transaction user purchases or is permitted to purchase the second target file of the other transaction user unit 104, the transaction user who purchases or is permitted to purchase or be permitted to be permitted the first target file of the related basic technology of the owner unit 101, so that the second target file purchased or permitted to be utilized can be implemented. Here, the income of the owner unit 101 may be allocated according to the transaction amount allocation information in the above 1, and the income of the transaction user unit 104 selling a patent or selling a patent license may be allocated according to the transaction amount allocation information in the above 2.
FIG. 2 is a flow diagram illustrating a block chain based file transaction method according to an embodiment of the invention. As shown in fig. 2, the method comprises the steps of:
in step S201, the owner unit sends the first file to the blockchain platform.
Wherein the first file includes: a first rights identification file, a first identity information file, a first target file, and a first transaction type file.
Step S202, the blockchain platform generates a first digital currency address corresponding to the first file according to the first file, and sends the first file and the first digital currency address corresponding to the first file to the monitoring unit.
In step S203, the monitoring unit determines file association information corresponding to the first digital currency address according to the first file and the first digital currency address corresponding to the first file, and sends the file association information corresponding to the first digital currency address to the blockchain platform.
Wherein the file association information includes: digital certificates, transaction amount allocation information, and digital currency amounts. Specifically, the monitoring unit determines a digital certificate corresponding to the first digital currency address according to a first ownership certificate in a first file corresponding to the first digital currency address; determining transaction amount distribution information corresponding to the first digital currency address according to the first identity information file in the first file corresponding to the first digital currency address; and evaluating value grades of different transaction types corresponding to the first target file in the first file corresponding to the first digital currency address according to the first target file in the first file corresponding to the first digital currency address and the first transaction type file, and determining the digital currency amount corresponding to the first digital currency address according to the value grades.
Step S204, the blockchain platform generates first file transaction information of different transaction types according to the received file association information which is sent by the monitoring unit and corresponds to the first digital currency address.
In step S205, the transaction user unit sends the first file transaction request of the transaction user to the transaction execution unit.
In step S206, the transaction execution unit sends the received first file transaction request to the blockchain platform.
After the blockchain platform receives the first file transaction request sent by the transaction execution unit, the blockchain platform can judge and process the received first file transaction request according to the first file transaction information to obtain a judgment processing result, then the transaction execution unit receives the judgment processing result sent by the blockchain platform and completes the first file transaction according to the judgment processing result. Specifically, the implementation can be performed by step S207 to step S211.
