The control unit 120 may generate a ticket including information on the transaction based on the transaction of the virtual currency according to the transaction request of the peer 20 constituting the block chain network.

To this end, the control unit 120 may obtain a transaction request for virtual currency from the peer 20 constituting the block chain network according to an embodiment.

For example, the control unit 120 may obtain a transaction request from the block chain network for the first peer 21 to request transfer of virtual currency to the second peer 22, and provide virtual currency from the transaction request. It is possible to obtain the electronic wallet address of the first peer 21, the electronic wallet address of the second peer 22, and the amount of virtual currency.

And the control unit 120 may generate a ticket based on the transaction of the virtual currency.

According to one embodiment, the controller 120 may generate a ticket including information on a transaction of a virtual currency.

For example, in the transaction request obtained from the first peer 21 , the control unit 120 includes '0.1 coin', which is the amount of virtual currency, the electronic wallet address 'e39w39' of the first peer 21, and the first peer 21 ) may generate a ticket including 'x80ys23', which is the electronic wallet address of the second peer 22, which is the counterparty to the transaction.

According to another embodiment, the controller 120 may generate a ticket having a temporary value corresponding to the virtual currency.

For example, the control unit 120 includes information on the amount of virtual currency, such as a digitally implemented bill, but variable data in which the electronic wallet address, which is the identification information of the peer 20 holding the ticket, is continuously recorded. You can create a ticket with a structure.

In this case, the control unit 120 may perform a transaction by transferring a previously generated ticket held by the peer to another peer.

For example, if the amount of virtual currency included in the ticket held by the first peer 21 is smaller than the amount of virtual currency requested by the first peer 21, the controller 120 controls the first peer 21 to At the same time as transferring the held ticket to the second peer 22, a ticket can be created for the remaining amount of the requested virtual currency except for the amount of virtual currency included in the ticket, and the generated ticket is transferred to the second peer (22) can be provided to perform the transaction.

According to another embodiment, the controller 120 may update the owner of the ticket.

For example, when a ticket is transferred from the first peer 21 to the second peer 22, the control unit 120 generates the electronic wallet address of the first peer 21 matching the identification information of the ticket stored in the database. 2 It can be changed to the electronic wallet address of the peer 22 .

Alternatively, for example, the control unit 120 may search the electronic wallet address of each peer 20 constituting the block chain network based on the identification information of the ticket to identify whether the ticket is held, and the peer for which the ticket is retrieved. According to whether the electronic wallet address of (20) and the electronic wallet address of the peer matched with the pre-stored ticket are the same, the electronic wallet address of the peer matched with the ticket may be updated.

In addition, according to an embodiment, the controller 120 may restrict access to some of the virtual currency held by the peer 20 with respect to the peer 20 according to the provision of a ticket.

For example, the control unit 120 may temporarily limit the transaction so that only an amount excluding the virtual currency included in the ticket among the total amount of virtual currency included in the electronic wallet of the first peer 21 is allowed.

Thereafter, the control unit 120 may remove the ticket when the block including the transaction of the virtual currency is identified.

For example, the control unit 120 may obtain a block synchronized through the block chain network, identify a transaction of a virtual currency included in the obtained block, and remove a ticket corresponding to the transaction of the identified virtual currency. have.

In this case, the controller 120 may search for a peer holding a ticket corresponding to the transaction of the virtual currency recorded in the block.

For example, the control unit 120 may search whether or not a ticket is stored in each peer 20 while traversing the peers 20 constituting the block chain network. Alternatively, for example, the controller 120 may search whether the ticket is stored in the peer 20 corresponding to the electronic wallet address stored in correspondence with the ticket.

According to one embodiment, the controller 120 may delete a ticket held by the peer 20 .

For example, the controller 120 may search for a ticket corresponding to a transaction of a virtual currency recorded in a block among tickets previously stored in the database and delete the searched ticket, and retrieve the electronic wallet address of the peer stored in response to the deleted ticket. A ticket stored in the peer 20 may be deleted by identifying the peer that has received the ticket based on the identification.

According to another embodiment, the controller 120 may remove the ticket by transferring the ticket held by the other peer from the other peer to the peer.

For example, the controller 120 transfers the ticket from the second peer 22 holding the ticket to the first peer 21 according to the transaction request of the first peer 21 and includes the ticket with the peer owning the ticket. You can remove a ticket by deactivating the ticket by making the same peer providing the amount of virtual currency.

Accordingly, even if omitted below, the contents described above with respect to the transaction providing apparatus 10 illustrated in FIG. 2 may also be applied to the transaction providing method according to the embodiment illustrated in FIGS. 3 to 4 .

Referring to FIG. 3 as a flowchart for explaining a method for providing a transaction according to an embodiment, the transaction providing apparatus 10 may obtain a transaction request from a peer constituting a block chain network (S3001).

For example, the transaction providing device 10 may obtain the amount of virtual currency from the first peer 21, the electronic wallet address of the first peer 21 who will provide the virtual currency, and the second peer 22 to obtain the virtual currency. e-wallet address can be obtained through a transaction request.

Or, for example, the transaction providing apparatus 10 may obtain a transaction request for a virtual currency of the first peer 21 from a server (not shown) that generates a block in the block chain network.

In addition, the transaction providing device 10 may generate a ticket based on the virtual currency transaction (S3002).

That is, the transaction providing apparatus 10 may generate a ticket based on the transaction of the virtual currency corresponding to the transaction request obtained in step S3001.

4 is a flowchart illustrating in detail a process of generating a ticket for a transaction according to an exemplary embodiment.

Referring to FIG. 4 , the transaction providing device 10 can identify whether the peer 20 who requested the transaction holds a ticket (S4001), and if the transaction is requested, the amount of the previously held ticket is determined by the transaction request (S4001). It can be identified whether it is less than the amount of virtual currency (S4002).

If the amount of the ticket is less than or equal to the amount of the requested virtual currency, the transaction providing apparatus 10 may generate a ticket for the amount exceeding the amount of the ticket among the amount of the requested virtual currency (S4003).

On the other hand, when the peer 20 does not hold a ticket in step S4001 or the amount of the virtual currency requested for a transaction in step S4002 exceeds the ticket held by the peer 20, the transaction providing device 10 sends a transaction request It is possible to create a ticket for the amount of virtual currency (S4004).

At this time, in step S4003 or step S4004, respectively, the transaction providing apparatus 10 may generate a ticket as in the following embodiment.

According to one embodiment, the transaction providing apparatus 10 may generate a ticket including information on a transaction of a virtual currency.

According to another embodiment, the transaction providing apparatus 10 may generate a ticket corresponding to the amount of the virtual currency included in the transaction of the virtual currency.

For example, the transaction providing apparatus 10 may generate a ticket including information on an amount corresponding to the amount of virtual currency, but including identification information of a peer holding the ticket.

In addition, the transaction providing apparatus 10 may generate a ticket by encrypting information included in the ticket.

According to one embodiment, the transaction providing device 10 generates a ticket by adding a parity bit that can check forgery and forgery of bits corresponding to the information included in the ticket in order to prevent forgery and falsification of information included in the ticket. can

For example, the transaction providing apparatus 10 may generate a ticket by adding a parity bit so that the sum of bits that have undergone encryption using a public key with respect to bits representing information included in a ticket becomes a specific value.

According to another embodiment, the transaction providing apparatus 10 may generate a ticket including encrypted data by encrypting information included in the ticket.

For example, the transaction providing apparatus 10 may encrypt transaction information of a virtual currency using an encryption algorithm such as a hash function, a Huffman code, or a public key method, and may generate a ticket including the encrypted information.

And, according to an embodiment, the transaction providing apparatus 10 may store the generated ticket in a database.

For example, the transaction providing device 10 may store identification information on the generated ticket in a database, but match the identification information of the ticket to the electronic wallet address of the peer 20 holding the ticket and store it.

Thereafter, the transaction providing apparatus 10 may perform a transaction by providing a ticket to another peer, which is a counterpart to the peer transaction (S3003).

For example, in step S3002, the transaction providing device 10 writes the electronic wallet address of the second peer 22, which is the transaction counterparty of the first peer 21, for identification information on the ownership of the stored ticket. It can be provided to the second peer 22 .

Or, for example, the transaction providing device 10 may transmit the ticket generated in step S3002 to the second peer 22 to be stored in the terminal of the second peer 22 , and to the second peer 22 . Based on the identification information of the stored ticket, the owner matching the ticket stored in the database may be updated with the electronic wallet address of the second peer 22 .

In this case, the transaction providing apparatus 10 may perform a transaction using a ticket previously held by the peer 20 .

Through this, by performing a transaction by providing a ticket as a substitute for a virtual currency, the transaction can be secured until the transfer of the virtual currency is propagated in the block chain network, so that the transaction of the virtual currency can be performed quickly.

And the transaction providing device 10 may detect whether a block in which a transaction of virtual currency is recorded is identified (S3004).

For example, the transaction providing device 10 may detect a block newly shared in the block chain network after the transaction request of the peer 20 is propagated through the block chain network, and virtual currency included in the detected block of transactions can be identified.

When a virtual currency transaction corresponding to the transaction request obtained in step S3001 is detected in step S3004, the transaction providing apparatus 10 may remove the ticket corresponding to the transaction described in the block (S3005).

According to one embodiment, the transaction providing apparatus 10 may remove a ticket corresponding to a transaction described in a block among tickets stored in the database.

For example, when the ticket is provided by changing the ownership of the ticket to another peer in step S3003, the transaction providing device 10 may search for a ticket stored in the database based on the electronic wallet address of the other peer, and the retrieved ticket You can delete a ticket with an amount equal to the amount of virtual currency listed in the middle block.

According to another embodiment, the transaction providing apparatus 10 may remove the ticket stored in the peer 20 .

For example, when a ticket is transmitted and provided to the peer 20 in step S3003, the transaction providing device 10 sends the peer 20 to the peer 20 based on the electronic wallet address of the peer 20 in the transaction record recorded in the block. It is possible to search, and from among the tickets stored in the searched peer 20, a ticket corresponding to the transaction record recorded in the block can be deleted.

In this way, by deleting the ticket for the transaction where the transfer of virtual currency is propagated on the block chain network and the block is created, it is possible to prevent double transaction due to the transfer of the ticket that the transfer of virtual currency is completed.
