Hereinafter, an embodiment of the operation performed by the service server 100 in the tracking service system 10 and the block chain network system 20 will be described along with FIGS. 4 to 10 .

4 is a flowchart of an operation performed by the service server 100 in an example for manufacturing and distribution according to an embodiment.

Referring to FIG. 4 , the engine terminal 200 - 1 of a manufacturing organization that manufactures mobile furniture may be in a state in which the mobile device is manufactured ( 1100 ).

The institution terminal 200-1 generates a token generation request message to specify the manufactured mobile furniture in the block chain network system 20, and sends the token generation request message to the service server 100 or the block chain network system 20 It can be transmitted (1101).

The token creation request message is a serial number that specifies the manufactured mobile device, QR code, type of mobile device, manufacturer information, model name, vehicle identification number, parts information, manufacturing year, or the requested price at which the manufacturer wishes to sell the mobile device. may include information about

The service server 100 or the blockchain network system 20 may receive a token generation request message from the institution terminal 200 - 1 . The service server 100 or the blockchain network system 20 provides a token for specifying a mobile device based on the token generation request message to the blockchain account information of the institution terminal 200-1 (ex. the blockchain wallet of the institution node) can be issued as

As an example, the reward module 125 of the service server 100 calculates ( 1102 ) the amount of tokens corresponding to the price of the mobile device based on the information included in the received token generation request message, and sends the tokens to the institutional terminal ( 1102 ). 200-1) can be issued to the blockchain account (1103).

As an example, the contract module 123 of the service server 100 calculates the quantity of tokens to be issued based on the information of the token generation request message, and a token that specifies the movement mechanism in the block chain account of the subject who sent the token generation request message. The first smart contract of the protocol for issuing can be generated in advance in the block chain network system 20 . When a token generation request message is generated according to the first smart contract, the block chain network system 20 calculates a quantity of tokens corresponding to the price of the mobile device based on the information included in the token generation request message (1102) , the token may be issued to the blockchain account of the institution terminal 200 - 1 ( 1103 ).

As an example, the service server 100 or the first smart contract combines the information included in the token generation request message and the subscriber information of the institution terminal 200-1 and calculates with a predetermined hash generation algorithm to specify the mobile device. You can create tokens.

For example, since the issued token specifies a mobile device, transfer may be restricted depending on circumstances.

For example, a full node may agree to allow a transaction for the movement of tokens only if the holder of the corresponding movement mechanism changes.

For example, a smart contract may include a digital command of a protocol that allows the token holder to move the token only when the holder of the corresponding transfer mechanism changes. For example, the token can be transferred only when the account holding the token receives the cryptocurrency corresponding to the token from the account that wants to purchase the mobile device. there is.

That is, the token according to the embodiment of the present invention operates as an independent token issued for each object in order to specify each object of the movement device, and different tokens may be issued for each object even for the movement mechanism of the same model. The token may be matched with the price of cryptocurrency used in the blockchain network system 20 . The quantity of issued tokens may mean the price of the mobile device, and the holder of the issued token may mean the subject holding the corresponding mobile device.

The institutional terminal 200 - 1 may be specified as the entity that manufactured the mobile device by holding a token issued by specifying the mobile device in the block chain account and being recorded as the first holder of the token. The institutional terminal 200 - 1 may be recorded as being in possession of the corresponding transfer device until the token is transferred to another blockchain account. In the block for generating the corresponding token, information about the token holder and the moving mechanism may be recorded together. For example, token information includes manufacturer, model name, vehicle identification number, important parts, country of origin of parts, assembly place, quality checker, confirmation date and time, shipping place, shipment destination, shipment date and time, and certification body information for each item. may contain information.

The institution terminal 200 - 1 may transmit an information initiation request message of the mobile appliance to the service server 100 or the blockchain network system 20 in order to sell the mobile appliance it possesses to another institution or consumer ( 1104 ). The information initiation request message may include margin information to be added by the subject holding the token in addition to the currently issued token quantity.

The service server 100 or the blockchain network system 20 may receive the information initiation request message and additionally issue a token corresponding to the margin information.

As an example, the compensation module 125 of the service server 100 additionally issues tokens in a quantity corresponding to the margin price desired by the institution terminal 200 - 1 based on the margin information included in the received information disclosure request message. and (1105), it is possible to transfer the additionally issued token to the blockchain account of the institutional terminal 200-1 (1106).

As an example, the contract module 123 of the service server 100 determines the quantity of tokens to be issued based on the margin information of the information disclosure request message, and issues additional tokens to the block chain account of the subject who sent the token generation request message. The second smart contract of the protocol may be generated in advance in the blockchain network system 20 . The blockchain network system 20 verifies the corresponding token generation request message according to the second smart contract, additionally issues tokens of the quantity corresponding to the price of the corresponding margin information (1105), and sends the additionally issued tokens to the institutional terminal 200 It can be transferred to the blockchain account of -1) (1106). The second smart contract may include a digital instruction of a protocol to burn the additionally issued token if the corresponding mobile device is not sold within a predetermined period or the disclosure of information is withdrawn.

Based on the information disclosure request message, the service server 100 discloses information on the blockchain ledger, including all records of the creation, movement, issuance, and incineration of tokens for the corresponding movement device, to the platform that provides the tracking service. can (1107).

In order to purchase the mobile device, the institutional terminal 200-2 of the distribution institution wishing to purchase the mobile device held by the institution terminal 200-1, currency corresponding to the amount of tokens disclosed in the platform providing the tracking service. may be transmitted to the service server 100 or the blockchain network system 20 (1108).

For example, when the institutional terminal 200 - 2 transmits real money to the service server 100 , the service server 100 may receive a deposit of real money at a price corresponding to the amount of tokens disclosed through a bank account ( 1108). When the reward module 125 of the service server 100 confirms the deposit of the corresponding real currency (1109), the token for specifying the corresponding mobile device is provided to the institution terminal 200-1 in the blockchain of the institution terminal 200-2. Request to the institution terminal 200-1 or the block chain network system 20 to transfer the account information and deliver the mobile device, and when it is determined that all the requests have been fulfilled, the deposit received from the institution terminal 200-2 Real money may be deposited into the bank account of the institution terminal 200 - 1 ( 1111 ).

In this case, the contract module 123 of the service server 100 transmits the corresponding token to the predetermined contract account when the transaction message for the transfer of the cryptocurrency of the price corresponding to the specific token and the receipt of the mobile device is confirmed. Through the change of the holder of the token by transferring to the blockchain account of one entity, the third smart contract of the protocol for recording the change of the holder of the mobile device may be generated in the blockchain network system 20 in advance. In this case, when the institutional terminal 200-2 deposits cryptocurrency into the contract account, the blockchain network system 20 confirms the transfer of cryptocurrency at a price corresponding to the amount of tokens initiated according to the third smart contract. and when it is confirmed that the institution terminal 200-2 has received a transaction message for receiving the mobile device from the institution terminal 200-1 (1109), it is held in the blockchain account of the institution terminal 200-1 The token can be transferred to the block chain account of the institutional terminal 200 - 2 ( 1110 ). The third smart contract may include a digital instruction of a protocol for recording a transaction including transfer information for moving the token and information on a recipient of the token in a block.

The blockchain account of the institutional terminal 200-2 receives the token issued by specifying the mobile device, and is recorded as the current holder of the corresponding token, so that the token is transferred to the blockchain account of another entity. state can be recorded. In addition, information about the token holder and the movement mechanism may be recorded together in the block for the corresponding token transfer. For example, the distributor, model name, vehicle identification number, important parts, shipment location, shipment destination, shipment date and time, and certification authority information for each item may be included.

Meanwhile, although the example of FIG. 4 has been described as an example of a distribution process between the institution terminal 200-1 and the institution terminal 200-2, the institution terminal 200-1 and the institution terminal 200-n shown in FIG. ), the operation according to the above-described embodiment may be applied between each subject from the institution terminal 200 - 2 to the user terminal 300 which is an end consumer.

According to the embodiment of FIG. 4 , the institution terminal 200 - 1 and the institution terminal 200 - 2 which are the subjects participating in the generation of the transaction according to the ownership change, and the full node group participating in the verification of the transaction generated by each subject can receive cryptocurrency compensation according to the protocol of the blockchain network system 20 described in FIG. 2 .

The service server 100 or the blockchain network system 20 may burn some of the tokens issued to the mobile device based on the determined token burn amount (1302).

As an example, the control module 121 of the service server 100 may incinerate the token issuance amount at a ratio calculated in consideration of the difference between the manufacturing time and the current time. For example, the control module 121 may incinerate a token corresponding to a ratio of (current year - release year + 1)*x (ex. x is 0.15). The x may be determined based on the information of the mobile device input at the time of token issuance. In addition to the constants as in the above-described example, x may be in the form of a decreasing function inputting (current year - release year +1).

For example, the contract module 123 of the service server 100 automatically sets a preset quantity (ex. (current year - release year + 1) * x ), the fourth smart contract of the protocol for incinerating the tokens may be generated in advance in the blockchain network system 20 . The fourth smart contract may include a digital command of a protocol for burning tokens in the form of an exponential function, a log function, or an nth-order function when a predetermined period elapses.
