When the sale is completed within the set initial sale period, the first digital asset-backed securities-A can be traded before the initial sale period.

When the sale is not completed within the set initial sale period, the first digital asset-backed securities-A can be traded after the initial sale period. The first digital asset-supported securities-A that has not been sold can be delivered to the wallet of the digital asset-supported securities issuance and transaction service providing node 410.

Then, in the transaction step, the first digital asset-supported securities-A sold through the digital asset-supported securities issuance and transaction service utilization device 450 and stored in the digital asset-supported securities issuance and transaction service provider node 410 due to the unfinished sale The first digital asset-backed securities-A of the wallet is traded.

Unlike existing exchanges, the transaction information of the first digital asset-supported securities-A is included in the transaction to be transmitted to the digital asset-supported securities issuance and transaction service operation node 420, and can be passed through the digital asset-supported securities issuance and transaction service operation node 420 The verification is recorded on the blockchain. The transaction information may include information related to the seller of the first digital asset-backed securities-A, the quantity sold, the buyer of the first digital asset-backed securities-A, the quantity purchased, and the transaction time.

According to the embodiment of the present invention, the digital asset-backed securities issuance and transaction service operation node 420 is a small number of selected nodes, and a small number of selected nodes can quickly generate blocks to almost instantly transfer the first digital asset-backed securities-A Transaction information is recorded on the block. In order to separately set up such a digital asset-supported securities issuance and transaction service operation node 420, a separate blockchain code can be set in the digital asset-supported securities issuance and transaction service operation node 420, or it can be set up to separately manage the issuance and transaction of digital asset-supported securities. The transaction service operates the channel of node 420. Set up a separate blockchain code or a separate channel to set up the work of the digital asset-supported securities issuance and transaction service operation node 420, and can restrict access to the data processed by the digital asset-supported securities issuance and transaction service operation node 420 Permissions.

Alternatively, according to an embodiment of the present invention, in addition to transaction information, sale request information and purchase request information can also be recorded on the block, and transactions can be performed on the block by matching the sale request information and purchase request information.

Specifically, when the digital asset-supported securities issuance and trading service utilization device (sale) requests the sale of 100 first-digital asset-supported securities-A at a price of 100,000 won per first-digital asset-supported securities-A, the exchange node According to the records on the blockchain, it can be judged whether the 100 first digital asset-backed securities-A exist in the wallet of the digital asset-backed securities issuance and transaction service utilization device (sale). Based on the records on the block, when the 100 first digital asset-backed securities-A exist in the wallet of the digital asset-backed securities issuance and transaction service utilization device (sale), the sale can be approved.

In this case, the first digital asset-supported securities-A, 100 units, and 100,000 won as the sale request information are included in the transaction and transmitted to the digital asset-supported securities issuance and transaction service operation node 420, and the digital asset-supported securities The verification of the issuance and transaction service operation node 420 is recorded on the blockchain.

Conversely, when the DAB issuance and transaction service utilization device (purchase) requests to purchase 100 first digital asset-supported securities-A at a price of 100,000 won per first digital asset-supported securities-A, the exchange node 430 can select The wallet record of the device (purchase) for digital asset support securities issuance and transaction services on the blockchain is used to determine whether there is a purchase asset that can purchase 100 first digital asset support securities-A at a price of 100,000 won/unit. Based on the records on the block, when there are purchase assets, purchase request information can be generated. In this case, as the purchase request information, the first digital asset-supported securities-A, 100 units, and 100,000 won are included in the transaction and transmitted to the digital asset-supported securities issuance and transaction service operation node 420, and can be passed through the digital asset-supported securities The verification of the issuance and transaction service operation node 420 is recorded on the blockchain.

If the sale request information and the purchase request information match on the blockchain, the transaction can be carried out and sent to the exchange node 430, digital asset support securities issuance and transaction service utilization device (sale), DAB issuance and transaction service utilization device (purchase ) Deliver transaction results.

When there is matching sale request information and purchase request information according to the blockchain code, a transaction can be performed, and the first digital asset-backed securities can be moved according to the transaction. When trading, 100 first digital asset-supported securities-A in the wallet of the digital asset-supported securities issuance and transaction service utilization device (sale) can be transferred to the digital asset-supported securities issuance and transaction service utilization device (purchase) In your wallet. Conversely, the assets corresponding to the 100 first digital asset-backed securities-A (for example, legal tender or digital assets) can be issued and traded to digital asset-backed securities from the wallet of the digital asset-backed securities issuance and transaction service utilization device (purchase) The service uses the wallet of the device (sold) to move.

The transaction fee of the digital asset-supported securities issuance and transaction service utilization device (sale) can be determined based on the number of second digital asset-supported securities stored in the wallet of the digital asset-supported securities issuance and transaction service utilization device (sale). Similarly, the transaction fee of the digital asset-supported securities issuance and transaction service utilization device (purchase) can be determined based on the number of second digital asset-supported securities stored in the wallet of the digital asset-supported securities issuance and transaction service utilization device (purchase).

That is, the transaction method of the embodiment of the present invention is different from the transaction on the previous ledger, and it can be a method of actually matching the sales request information and the purchase request information on the blockchain to conduct the transaction. By setting up a separate blockchain code or using a separate channel to connect digital assets to support the verification and agreement methods of securities issuance and transaction service operation nodes, it can be directly digitalized on the blockchain faster than the previous verification and agreement methods Asset-backed securities transactions, rather than digital asset-backed securities transactions on the ledger.

Moreover, according to the embodiment of the present invention, the second digital asset-supported securities can be exchanged by other external exchange nodes 460 except for the exchange node 430 granted permission by the digital asset-supported securities issuance and transaction service providing node 410 transaction. The wallet of the second digital asset-backed securities can also be opened to the external exchange node 460, so that the second digital asset-backed securities can be deposited or withdrawn. The deposit or withdrawal record of the second digital asset-backed securities can also be recorded on the blockchain. The external exchange node 460 can be set to execute only a part of the permission of the blockchain code on the blockchain network, or it can be set to deposit or withdraw a limited number of second digital asset-backed securities relative to a separate channel.

As described above, a single first digital asset-backed security can be issued by asset and traded on the exchange node 430. For example, the first digital asset-backed securities-A for real estate A, the first digital asset-backed securities-B for real estate B, the first digital asset-backed securities-C for real estate C, and the first digital asset-backed securities for real estate D can be issued separately. Digital assets support Securities-D and are traded through the exchange node 430.

Fig. 5 is a conceptual diagram showing a method for allocating asset returns based on a blockchain according to an embodiment of the present invention.

Figure 5 discloses the method of distributing asset income through the blockchain.

Referring to Figure 5, when the assets of the first digital asset-backed securities are issued with income, the proceeds of the assets of the first digital asset-backed securities can be distributed among the digital asset-backed securities issued and held in the wallet. Transaction service utilization device 550.

When allocating the monthly rental income to real estate A, the monthly rental income can be converted into a specific digital asset after being deposited. For example, when 100 million won is generated as the monthly rental income of real estate A, it is converted into digital assets corresponding to 100 million won, and the converted digital assets can be allocated to holdings based on the distribution information of the first digital asset support securities-A. There is a digital asset-backed securities issuing and trading service utilization device 550 of the first digital asset-backed securities-A.

For example, if the total issuance is 10,000, and the digital asset-supported securities issuance and transaction service utilization device A has 10, the amount equivalent to 1/1000 of the total amount of digital assets converted into monthly rent can be deposited in the digital asset support Securities issuance and transaction services are used in the wallet of device A. The virtual currency conversion and distribution record of the monthly rent of such real estate can be included in the transaction and recorded on the blockchain.

Fig. 6 discloses a method for determining the price of the first digital asset-backed securities according to an embodiment of the present invention.

When the current price of the first digital asset-backed security input based on the blockchain code is below the lower limit price of the first digital asset-backed security, the digital asset-backed securities issuance and transaction service provider node can pass the target according to the blockchain code. A purchase order for a digital asset-backed security purchases the first digital asset-backed security sold at a price below the limit. According to the blockchain code, if the price of the first digital asset-backed securities is above the lower limit price, the digital asset-backed securities issuance and transaction service provider node can interrupt the purchase order.

The lower limit price of the first digital asset-backed security can be determined based on the price stability described in FIG. 3. Price stability can be set by asset. The lowest price of the first digital asset-backed security set in the lower limit range of price stability may be the lower limit price of the first digital asset-backed security. It is possible to invest according to the characteristics of each asset by setting the lower limit range of the price of the first digital asset-backed securities, and it can be set to not fall below the specified range based on the appraised price of real estate. In addition, the lower limit range of the price can be further adjusted by considering additional information transmitted to external nodes (for example, the publicized price of land, etc.). If the public land price drops, the lower price range can be relatively larger. On the contrary, if the land public price rises, the lower price range can be relatively smaller. Information related to the published price of land is transmitted to the blockchain network through external nodes, and the lower limit range of the price can be set based on the information related to the transmitted land published price and the set chain code.

Fig. 7 is a conceptual diagram showing an asset sale procedure of an embodiment of the present invention.

Figure 7 discloses a method for trading assets issued and traded with digital asset-backed securities.

Referring to FIG. 7, in order to buy or sell assets issued and traded in digital asset-backed securities, a step of purchasing the first digital asset-backed securities of the asset may be performed.

The first digital asset-backed securities for assets does not give the right to hold actual assets, but can give the right to the profits generated by the operation of the asset and the increase in the value of the asset. As described above, the monthly rental income of real estate A can be distributed based on the first digital asset-backed securities-A. Or, the increase in the value of real estate A may cause the value of the first digital asset-backed securities-A to increase, and the owner of the first digital asset-backed securities-A can sell the first digital asset-backed securities-A in the future along with the sale of real estate A , So that you can have the right to the profits generated as the value of real estate increases.

In order to transfer the ownership of the real estate A issued by the first digital asset-backed securities-A, the first digital asset-backed securities-A can be purchased. The digital asset-backed securities issuance and transaction service provision node 710 sets a purchase price for the purchase of the first digital asset-backed securities-A to transfer the ownership of the real estate A. The digital asset-backed securities issuance and transaction service provider node 710 can consider the current price of the first digital asset-backed securities-A, the initial price of the first digital asset-backed securities-A, and the sale price of real estate A based on the blockchain code. Determine the purchase price of the first digital asset-backed security-A.

In addition, the digital asset-backed securities issuance and transaction service providing node 710 can also determine the purchase period of the first digital asset-backed securities-A. The purchase period of the first digital asset-backed securities-A can be determined by considering the owner information of the first digital asset-backed securities-A, the information on the sale period of the real estate, etc.

The digital asset-supported securities issuance and transaction service provider node 710 can use the digital asset-supported securities issuance and transaction service device 750 that keeps the first digital asset-supported securities-A in the wallet within the purchase period of the first digital asset-supported securities-A Notice to purchase the first digital asset-backed securities-A.

The digital asset-supported securities issuance and transaction service utilization device 750 can sell the first digital asset-supported securities-A at the purchase price of the first digital asset-supported securities-A, and the sales records of the first digital asset-supported securities-A are included in the transaction In and recorded on the blockchain.

If the purchase step is performed above the set threshold before the purchase period of the first digital asset-backed securities-A set according to the blockchain code or the purchase period of the first digital asset-backed securities-A has passed, it can be performed Steps for the transfer of ownership of real estate A. The remaining critical quantity of the first digital asset-backed securities-A can be sold in batches at a prescribed amount, and the digital asset-backed securities issuance and transaction service utilization device 750 can be used to directly sell the first digital asset-backed securities-A through the guarantee step Provide the amount of sale.

Through the repurchase step as described above, the ownership of the real estate A is transferred, and the first digital asset-supported securities-A for the real estate A can all be written off. Or according to the embodiment of the present invention, the repurchase period of the first digital asset-backed security-A and the repurchase price of the first digital asset-backed security-A can be determined in the following manner.

The repurchase period of the first digital asset-backed securities-A may consider the distribution information and investment amount distribution information of the first digital asset-backed securities-A based on the information on the blockchain, and the first digital asset-backed securities -A’s owner determines the holding tendency information of the first digital asset-backed securities-A, etc. At the time point when the repurchase is determined, the information related to the owner of the first digital asset-backed securities-A recorded on the block can be extracted. The greater the number of owners of the small first digital asset-backed securities-A, the longer the repurchase period of the first digital asset-backed securities-A can be. Moreover, the proprietor of the first digital asset-backed securities-A has a relatively higher propensity to hold the first digital asset-backed securities-A, and the repurchase period of the first digital asset-backed securities-A can be relatively longer.

After this repurchase announcement, the repurchase result of the first digital asset-backed securities-A that occurred through the repurchase step can be fed back to adjust the length of the repurchase announcement period. For example, if the first digital asset-backed securities-A owner’s distribution information and investment amount distribution information in the similar range, the first digital asset-backed securities-A owner’s propensity to hold the first digital asset-backed securities-A If the repurchase step is shorter than the set time, the future repurchase period can be set to be relatively short. Conversely, if the first digital asset-backed securities-A owner’s distribution information and investment amount distribution information, the first digital asset-backed securities-A owner’s propensity to hold the first digital asset-backed securities-A in the similar range If the repurchase step is longer than the set time, the future repurchase period can be set to be relatively long. In this way, a large amount of the first digital asset-backed securities-A can be repurchased as quickly as possible.

The repurchase price of the first digital asset-backed securities-A can be determined by considering the past price and the selling price of the real estate A. If the current price of the first digital asset-backed security-A is higher than or equal to the price of the first digital asset-backed security-A converted based on the selling price of the real estate A, the current price of the first digital asset-backed security-A can be Repurchase price. Conversely, if the current price of the first digital asset-backed security-A is lower than the price of the first digital asset-backed security-A converted based on the sale price of the real estate A, then the converted price of the first digital asset-backed security-A can be Is the repurchase price. The price of the first digital asset-backed security-A converted based on the sale price of the real estate A may not be a value obtained by simple arithmetic division, but determined by a separate value calculation of the first digital asset-backed security-A the price of.

Furthermore, according to the embodiment of the present invention, the repurchase price of the first digital asset-backed securities-A can be set according to the repurchase period. In order to repurchase the first digital asset-backed securities-A faster, it can be set to sell the first digital asset-backed securities-A faster, the higher the price will be purchased. The price can be set for the first digital asset-backed security-A by dividing the repurchase range into multiple lower-level repurchase ranges. In this way, it can be set so that everyone can sell the first digital asset-backed security faster -A.

Fig. 8 is a conceptual diagram showing a method of trading digital asset-backed securities according to an embodiment of the present invention.

Figure 8 discloses a method of executing the first digital asset-backed securities transaction that occurs by the exchange node.

Referring to FIG. 8, a method for selling and purchasing the first digital asset-backed securities using the three digital asset-backed securities issuance and transaction service utilization devices is exemplarily disclosed. This is just an example, and it can also be applied to the trading of the first digital asset-backed securities of multiple other digital asset-backed securities issuance and transaction service utilization devices.

It can be assumed that the first digital asset-supported securities issuance and transaction service utilization device 810 sells three first-digit asset-supported securities, the second digital asset-supported securities issuance and transaction service utilization device 820 purchases one first-digit asset-backed securities, and the third digital The case where the asset-backed securities issuance and transaction service utilization device 830 purchases two first-digit asset-backed securities.

The first digital asset-supported securities issuance and transaction service utilization device 810 can generate a sale order 815 for three first digital asset-supported securities. The sale order 815 may include seller information, information on the quantity of digital asset-supported securities sold, information on the price of digital asset-supported securities sold, and signature information of the first digital asset-supported securities issuance and transaction service utilization device 810.

The second digital asset-backed securities issuance and transaction service utilization device 820 can generate first purchase orders for the two first digital asset-backed securities. The first purchase order may include the first buyer information (or the identification information of the second digital asset-backed securities issuance and transaction service utilization device), the first purchase of digital asset-backed securities quantity information, the first purchase amount information, and the second digital asset support Securities issuance and transaction services use device signature information.

The third digital asset-supported securities issuance and transaction service utilization device 830 can generate a second purchase order 835 for a first digital asset-supported securities. Similarly, the second purchase order 835 may include second buyer information (or identification information of the third digital asset-backed securities issuance and transaction service utilization device), second purchase of digital asset-backed securities quantity information, second purchase amount information, and third Digital asset support securities issuance and transaction services using device signature information.

If the sale order 815, the first purchase order 825, and the second purchase order 835 match, the exchange node can generate a transaction 850 containing transaction information based on the sale order 815, the first purchase order 825, and the second purchase order 835. And to the digital asset-backed securities issuance and transaction service operating device transmission. The issuance and transaction service operating device of digital asset-supported securities can verify transactions and record transaction information on the block.

The transaction information can be used as input values to include the quantity information of the digital asset-supported securities for sale included in the sale order 815, the first purchase amount information included in the first purchase order 825, and the second purchase included in the second purchase order 835. Amount information.

In addition, the transaction information can be used as an output value to include the first digital asset-supported securities information to be transmitted to the second digital asset-supported securities issuance and transaction service utilization device 820, and the third digital asset-supported securities issuance and transaction service utilization device to be transmitted The first digital asset-supported securities information of 830 and the sales amount information based on the sale to be transmitted to the first digital asset-supported securities issuance and transaction service utilization device.

When the verification of the transaction 850 containing transaction information is performed or the transaction information is recorded on the block after the verification step, the sale amount is deposited in the wallet of the first digital asset support securities issuance and transaction service utilization device 810, and the first digital asset support The securities can be delivered to the wallet of the second digital asset-supported securities issuance and transaction service utilization device 820 and the wallet of the third digital asset-supported securities issuance and transaction service utilization device 830.

According to the embodiment of the present invention, multiple nodes in the blockchain network may have a layered structure according to limited functions. The digital asset-supported securities issuance and transaction service providing nodes can be set as the first-tier nodes, the second-tier nodes, the third-tier nodes, and the fourth-tier nodes according to the functions and data access rights. For example, the above-mentioned digital asset-supported securities issuance and transaction service operation nodes, exchange nodes, value evaluation devices, and digital asset-supported securities issuance and transaction service utilization devices can be based on the tasks that can be performed in the blockchain network and the accessible The data is divided into first-level nodes, second-level nodes, third-level nodes, and fourth-level nodes. The first-level nodes, second-level nodes, third-level nodes, and fourth-level nodes can be classified based on channel, chain code, and data classification.

Specifically, the first-tier nodes, the second-tier nodes, and the third-tier nodes can be connected through the first channel, and the fourth-tier external nodes can be connected through the second channel. As a result, the fourth-tier external nodes can be separated from the first-tier nodes, the second-tier nodes, and the third-tier nodes, and the fourth-tier nodes can perform limited tasks on the blockchain network.

Then, the channel code A can be set in the first layer node, the second layer node, and the third layer node, and the channel code B can be set in the third layer node. The first layer node and the second layer node provided with channel code A can share data related to channel code A, but the third layer node provided with channel code B can share data related to channel code B. Thus, the third-tier nodes can be separated from the first-tier and second-tier nodes, and the third-tier nodes can perform limited tasks on the blockchain network.

Then, you can set up dedicated information to allow only the first-tier nodes among the first-tier nodes and the second-tier nodes to access. In this case, the dedicated data can only be accessed by the first-tier nodes, and the second-tier nodes may not be accessible. As a result, the first-tier nodes can be separated from the second-tier nodes, and the second-tier nodes can perform limited tasks on the blockchain network.

The permission setting per node in the embodiment of the present invention can be performed by a setting node (for example, a digital asset supporting securities issuance and transaction service providing node). The setting node may include: a communication part for communicating with an external node; and a processor operatively connected with the communication part. The processor can execute a method of setting permissions per node.

According to the embodiment of the present invention, different data transaction permission rights can be set restrictively on the blockchain in the manner described above according to the channel, chain code, and data classification.

Moreover, according to the embodiments of the present invention, limited functions can be given through channels, and channels can be restricted through the connection of independent channels and the connection of virtual channels. If multiple nodes bound through the same channel can be set as separate separate channels without interference from other nodes, they can be used as physically separated channels to set limited functions. For example, if node A, node B, and node C are used as nodes in the channel and can be connected without separate nodes in the middle, they can be set as independent channels as physically separated channels.

However, when it is necessary to use the same channel to set up, if the nodes in the channel are only connected through the nodes outside the channel in the middle, problems may occur in the security of the data transmitted through the channel. For example, if node A, node B, and node C as nodes in the channel can only be connected via node X, which is an intermediate node outside the channel, the physical separation channel cannot be set. In this case, according to the embodiment of the present invention, even in the case where nodes outside the channel are included in the middle, some channel section data separation encryption methods for setting as independent channels can be used.

When the data needs to be transmitted through the nodes outside the middle channel, the interval for data transmission through the nodes outside the middle channel can be set as the data separation and encryption interval, and the data can be separated and encrypted in the data separation and encryption interval. Specifically, the data transferred from the node in the channel to the node outside the channel can be encrypted and transferred to the node in the next channel in the bypass type. In this case, after the initial encryption, the encryption can be performed based on the encryption key value contained in the previously transmitted data, so it can be set to enable only the nodes in the channel that continue to change and decode the previously transmitted data. decoding. Multiple data separation encryption intervals can be set, and the encryption key values applicable to multiple data separation encryption intervals can be different from each other. In this way, even when the nodes outside the channel are in the middle, the nodes can be connected through virtual independent channels.

The above-described embodiments of the present invention can be implemented in the form of program instructions that can be executed by various computer components and recorded in a computer-readable recording medium. The computer-readable recording medium may include program instructions, data files, data structures, etc., alone or in combination. The program instructions recorded in the computer-readable recording medium may be specially designed and configured for the present invention, or may be program instructions known and used by those of ordinary skill in the computer software field. Examples of computer-readable recording media include magnetic media such as hard disks, floppy disks, and magnetic tapes, optical recording media such as CD-ROMs and DVDs, and magneto-optical media such as floptical disks. -optical medium) and hardware devices specially configured for storing and executing program instructions such as ROM, RAM, and flash memory. Examples of program instructions include not only machine codes generated by a compiler, but also high-level language codes that can be executed by a computer using an interpreter or the like. The hardware device can be changed by one or more software modules to perform the processing according to the present invention, and vice versa.
