Hereinafter, in an embodiment of the present invention, a blockchain system for issuance and transaction of DABS is disclosed.

3 is a conceptual diagram illustrating a block chain system for DABS issuance and/or transaction based on a block chain according to an embodiment of the present invention.

In FIG. 3, each component (or node, device) constituting a block chain system that performs DABS issuance and/or transaction based on block chain is disclosed.

Referring to FIG. 3 , the blockchain system (or blockchain network) for DABS issuance and transaction may include a DABS service device (or DABS service server), an exchange device (or an exchange server), and a DABS service user device. Hereinafter, the DABS service device may be used to mean including the aforementioned DABS service server, and the exchange device may be used to mean including the aforementioned exchange server. For convenience of description, it is expressed as a device, but each of the DABS service device, the exchange device, and the DABS service user device may be a node participating in the blockchain network.

A blockchain can be created that stores and/or processes various transactions generated by devices operating on a blockchain network. On each of the plurality of blocks included in the block chain, transaction information (or transaction information) generated for a certain period of time (for example, between the generation of the previous block and the time of the current block generation) and verified by a node (or a device on the block chain network) hash information) may be included.

Specifically, each block constituting the block chain includes transaction information generated on the block chain, information related to programming code (hereinafter referred to as block chain code) for performing specific algorithms based on block chains such as smart contracts, etc. can be saved. Alternatively, transaction information generated on the block chain is included in a separate storage unit, and only hash information about the transaction may be included on the block. The block chain code is installed according to the role of the node, and information related to the block chain code is stored It can also be stored on

After verification of the node's transaction, information about the block connected to the block chain may be transmitted to at least one device/node (eg, DABS service device, exchange device) in the block chain network. In this case, the node that verifies the transaction may be set separately.

Blocks connected to the blockchain can be created based on mining, and the mining method is based on POW (proof of work), POS (proof of stake), DPOS (delegated proof of stake), or hyperledger. A variety of methods may be used, such as how a node creates a block. A block is mined including information of the previous block, and this mining method can prevent tampering with transaction information recorded on the block.

The blockchain network is a network that serves as a platform that can also use other blockchain-based services such as the existing ethereum blockchain network, or its own blockchain for DABS issuance and transaction according to an embodiment of the present invention (eg, For example, it may be a network that creates a permissioned blockchain, a private blockchain).

DABS issuance and DABS transactions can be performed on the blockchain network based on the blockchain code recorded on the block by the DABS service device 310 or the blockchain code installed on each node.

The DABS service device 310 may be implemented to implement a DABS issuance and asset transaction service on a blockchain, and to provide a DABS issuance and transaction service. For example, the DABS service device 310 may store/install a blockchain code such as a smart contract or chaincode for DABS issuance and asset transaction service on a private blockchain (or node). Transactions generated by the DABS service device 310 and/or the exchange device 330 are processed based on the uploaded blockchain code, so that the DABS issuance and transaction service disclosed in the embodiment of the present invention can be provided below. .

DABS may be issued on the blockchain by the DABS service device 310 . As described above, DABS may be created upon issuance of digital asset-backed securities for assets (eg, real estate). Alternatively, a DABS is issued by a separate institution (eg, a depository system), and the DABS service device 310 may perform only management of the issued DABS.

DABS can be defined per asset. For example, it may be defined as DABS(A) for real estate A, DABS(B) for real estate B, DABS(C) for real estate C, and the like. DABS corresponding to each of a plurality of tradable assets issued as DABS may be traded on the exchange device 330 .

The DABS may correspond to at least one of the right to own the asset, the right to receive profit from the increase in the value of the asset, and the right to receive the profit from the asset management.

The DABS service device 310 may distribute profits according to the operation of assets issued as DABS to DABS owners. The DABS service device 310 may be a node of a foundation that provides DABS issuance and asset trading services.

In addition, according to an embodiment of the present invention, a contract for a transaction by asset may be separately set based on a block chain code. When purchasing DABS for an asset based on the blockchain code, the contract details are transferred to the DABS service device, so that the consent process for asset transaction can proceed. DABS purchaser's consent result information can be stored on the blockchain. For example, when a sale occurs for an asset that has issued a DABS, a repurchase procedure for the DABS owned by the DABS service device 310 may be performed. In this case, the DABS service user equipment 320 that owns the DABS may be obliged to sell the DABS. A special rule for an asset issued as such a DABS is defined, and when a DABS is purchased, it is transmitted to the DABS service user device 320 to proceed with the consent procedure for the special rule, and the consent result can be stored on the block chain.

The DABS service implemented on the blockchain by the DABS service device 310 will be described in more detail below.

In addition to this, there may be nodes that verify blocks on the blockchain. Verification nodes can verify transactions that occur on the blockchain, such as DABS issuance and DABS transactions. A verified transaction (or hash information related to a transaction) can be included in a block and recorded on the blockchain. The verification node may be a node to which authority for block mining is assigned by the DABS service device 310 (or a node in which a block chain code such as a separate chain code for mining is installed). The DABS service device 310 may also be one verification node.

The exchange device 330 may be implemented to provide a transaction service for assets issued as DABS. The exchange device 330 may trade DABS for an asset. Transaction information of DABS for assets generated on the exchange device 330 may be recorded on the blockchain as a transaction. Transaction fees may also be incurred for DABS transactions.

In addition, in the present invention, the value evaluation apparatus may be implemented to evaluate the asset value. For issuance of DABS for assets such as real estate, asset valuation may be made. The valuation device can perform valuation of the asset and transmit the valuation result on the blockchain network. Issuance of DABS for assets can be performed based on the result of valuation of assets transferred on the blockchain. The value evaluation device may directly transmit the value evaluation result on the blockchain network, but may also transmit the value evaluation result through the DABS service device 310 . For example, a valuation device may value real estate owned by a fund (private equity fund, public offering fund), or value real estate owned by a general owner other than a fund, and a DABS service device ( 310) may issue a DABS based on the valuation.

The DABS service user device 320 may be a device that trades or owns assets issued as DABS through an exchange node. For example, the DABS service user device 320 may trade DABS for a specific real estate and store it in a personal wallet.

In addition, the DABS service user device 320 may acquire the asset management profit determined based on the DABS. For example, when the DABS service user device 320 owns the DABS(A) of the real estate A, the operating profit of the real estate A may be distributed based on the DABS(A). Real estate A's monthly rental income issued with DABS(A) is deposited in fiat currency or other exchanged digital assets, and can be distributed according to the ownership of DABS(A).

According to an embodiment of the present invention, a separate intermediary node (eg, a trust node/bank node) that serves as a trust for separate assets and/or storage and transmission for digital assets may be added. Specifically, according to the request of the trust node, the DABS service device 310 may issue a DABS for the asset. In addition, the movement of securitized assets such as digital assets and fiat currency can be made through the trust node/bank node. For example, through the public offering procedure for assets, the DABS service user device 320 may deposit fiat currency corresponding to the issued DABS and receive DABS, and the fiat currency is an intermediary node such as a trust node/bank node. It can be provided to the owner/manager of the asset through Alternatively, the issuance of the DABS is performed by a separate management organization (eg, a server of the Depository), and the DABS service device may manage the DABS after issuance.

In addition, financial transactions (transactions on investment income, principal, interest, etc.) that are generated based on assets that have later issued DABS can be made through the trust node/bank node. For example, an investment return, interest, etc. generated based on an asset may be provided to the DABS service user device 320 through a trust node/bank node.

Hereinafter, in the embodiment of the present invention, for convenience of explanation, the operation of the intermediary node (eg, trust node/bank node) is not additionally mentioned, but a method for issuing digital asset-backed securities and trading digital asset-backed securities based on a block chain The operation of the intermediary node may occur in the above.

The above-described device/node includes a communication unit implemented to communicate with an external device and a processor operatively connected to the communication unit, and the processor may be implemented to perform an operation of each device/node.

Hereinafter, detailed DABS issuance and asset transaction procedures on the blockchain network are disclosed.

Referring to FIG. 4 , the DABS service device 410 may record a block chain code for DABS issuance and transaction on the block chain. For example, the DABS service device 410 may upload a block chain code capable of performing a role such as a smart contract on a block. Alternatively, the DABS service device 410 may install a block chain code for DABS issuance and transaction on the node.

In addition, the DABS service device 410 may request the value evaluation device 440 to evaluate the DABS target asset, and the value evaluation device 440 may evaluate the DABS target asset. The value evaluation device 440 may be at least one, and the value evaluation device 440 transmits a transaction including the asset value evaluation result information directly on the blockchain network or indirectly through the DABS service device 410 . may be

A transaction including asset value evaluation result information is verified by a verification node, and asset value evaluation result information (or a hash value of value evaluation result information) may be recorded on a block (or a separate storage space).

The blockchain code is called based on the asset value evaluation result information recorded on the block, and the sharing of the asset value evaluation result information and the issuance of DABS for the asset can be performed based on the blockchain code.

When the asset value evaluation result information is uploaded, the asset value evaluation result information may be transmitted to the DABS service device 410 and the exchange device 430 based on the block chain code. In addition, when asset value evaluation result information is uploaded, DABS issuance for assets can be performed based on the blockchain code. For example, the price of the DABS to be issued and the number of DABSs may be determined according to the price of the asset.

If there are multiple valuation results, the price of the asset may be determined by a predefined algorithm based on the blockchain code. For example, the price of the asset may be determined by determining the average value or the median value of the plurality of value evaluation results, or by setting different weights to each of the plurality of value evaluation results.

Alternatively, the recommended DABS price information or investment request information of a plurality of DABS service user devices 450 for a specific real estate may be collected, and the price of the DABS may be determined according to the recommended DABS price information or the investment request information.

The value evaluation device 440 may perform value evaluation on a private equity fund, a public offering fund, and real estate owned by an individual owner, and may issue a DABS according to the value evaluation result. According to the valuation, ownership is transferred by paying the real estate appraisal amount to the existing private equity funds, public offering funds, and individual owners, and thereafter, DABS for the real estate may be issued.

5 discloses a method of issuing DABS for assets based on a blockchain. In particular, a method of issuing a DABS for a valued asset (eg, real estate) is disclosed.

Referring to FIG. 5 , asset value evaluation result information may be shared with a plurality of DABS service user devices 550 using an exchange node.

Based on the asset value evaluation result information, DABS issuance related information may be collected from a plurality of DABS service user devices 550 . Information related to issuance of DABS may include information on investment demand for valued assets such as real estate. Specifically, the DABS issuance related information may include information on the number and price of a desired DABS when issuing the DABS for an asset. DABS issuance related information collected from a plurality of DABS service user devices can be input as a block chain code and finally used to determine the price and number of DABS for an asset.

The exchange device 530 may collect investment demand information for real estate A. For example, if 1,000 people request an investment of 5 million won on average, it may be determined that there is an investment demand of 5 billion won. In consideration of such investment demand, the number of DABSs and the price of DABSs serving as the minimum unit may be determined.

Specifically, investment demand information may be collected during the investment demand information collection period for issuance of DABS for the asset. The price of DABS may be determined based on the first DABS pricing step and the second DABS pricing step.

The primary DABS pricing may be determined based on the investment demand information collected during the investment demand information collection period. The investment demand information may be investment amount information for the corresponding asset. For example, information on these investment amounts such as 100,000 won, 1 million won, 2 million won, 10 million won, etc. may be input, and through the distribution of these investment amounts, the minimum investment amount, the maximum investment amount, and the most frequent investment amount , information such as an average investment amount may be extracted.

Based on the above investment demand information, transaction liquidity/price stability by DABS amount for asset trading can be determined. For example, if the initial price of DABS is set to 100,000 won, the number of DABSs per DABS service user device as an investor may be determined, and transaction liquidity/price stability due to the number of DABSs per DABS service user device may be determined. .

For example, the transaction liquidity may be determined based on the number of DABSs for each DABS service user device. Specifically, transaction liquidity may be determined based on the average number of DABSs for each DABS service user device. Price stability is based on the number of DABSs for each DABS service user device, and the proportion of devices using DABS issuance and trading services corresponding to the top holders of DABS (for example, more than a critical percentage (for example, 1%) of the total DABS). can be determined based on

The DABS service device can set the price of DABS by setting the required transaction liquidity/price stability for each asset. The DABS service device can also be set to have different transaction characteristics for each asset through the above method.

The above transaction liquidity and price stability can be adjusted according to the characteristics of the building.

According to an embodiment of the present invention, the DABS price may be changed according to required transaction liquidity and price stability. After the initial sale, DABS transaction details can be collected, and the existing DABS price and number of DABSs can be adjusted for transaction liquidity and price stability based on the DABS transaction history to have set transaction liquidity and price stability. Based on the block chain code, the adjustment procedure for the number of DABSs and DABS prices can be carried out to have separate transaction liquidity and price stability for each asset. Specifically, transaction liquidity and price stability are set on the blockchain code at the time of initial sale of assets issued with DABS, and adjustment of the DABS price and number of DABSs can be performed based on the set blockchain code.

In addition, according to an embodiment of the present invention, the DABS price may be set according to the investment purpose for the asset. The DABS service user device may invest in DABS for the main purpose of monthly rent, or may invest in DABS for the main purpose of increasing building prices. If the purpose is to increase the price of a building, it can be a relatively long-term investment compared to the case where the main purpose is monthly rent. Accordingly, information on the investment purpose of the DABS may be collected by collecting information on the investment purpose to determine the price of the DABS for transaction liquidity and price stability.

Also, according to an embodiment of the present invention, the price of the DABS may be determined in consideration of other assets having a high similarity to the asset. The most similar asset may be determined in consideration of the location, price, investment purpose, transaction record, etc. of the asset, and the DABS price may be determined by additionally considering the current DABS price of the asset. As such transaction records are accumulated, the DABS price of the asset can be set to suit the desired transaction liquidity and price stability.

In FIG. 6 , a method in which a DABS service user device 650 trades DABS in an exchange device is disclosed.

Referring to FIG. 6 , the exchange device 630 may sell and trade the DABS (A) of the real estate A.

In the first sale stage, the exchange device 630 may start an initial sale after issuance of the DABS(A) for the initial asset, and proceed with the transaction after the initial sale. For example, if DABS(A) is defined as 100,000 won for real estate A and the issuance amount of DABS(A) is set to 10,000, initial sales may proceed during the initial sale period. During the initial sale period, the sale may proceed without a separate transaction. During the initial sale period, the sales information of DABS(A) can be recorded on the blockchain. The sales information may include DABS(A) purchaser information and purchase quantity information of the DABS(A) purchaser. DABS(A) can be delivered to each DABS(A) buyer's wallet based on DABS(A) buyer information and DABS(A) buyer's purchase quantity information.

If the sale is completed during the set initial sale period, the transaction for DABS(A) may be started even before the initial sale period.

If the sale is not completed during the set initial sale period, the transaction for DABS(A) may be started after the initial sale period. The DABS (A) that has not been sold may be delivered to the wallet of the DABS service device 610 .

Thereafter, in the transaction step, the DABS (A) sold to the DABS service user device 650 and the DABS (A) stored in the wallet of the DABS service device 610 because the sale is not completed may be possible.

Unlike existing exchanges, transaction information for DABS(A) may be included in a transaction and transmitted to the verification node 620 , and may be recorded on the blockchain through verification of the verification node 620 . The transaction information may include information on the seller of the DABS(A), the quantity sold, the buyer of the DABS(A), the quantity sold, and the transaction time.

According to the embodiment of the present invention, the verification node 620 is a small number of selected nodes, and the transaction information of the DABS(A) will be recorded on the block in near real time through the fast block generation of the small number of selected verification nodes 620. can A separate blockchain code may be installed in the verification node 620 for separate setting of the verification node 620 or a channel for separately managing the verification node 620 may be established. The operation of the verification node 620 may be set through a separate block chain code setting or a separate channel setting, and access rights to data processed by the verification node 620 may be restricted.

Alternatively, according to an embodiment of the present invention, not only transaction information, but also sell request information and buy request information are recorded on a block, and a transaction may be performed through matching between the sell request information and the buy request information on the block.

Specifically, if the DAB service user device (sell) requests to sell 100 DABS(A) at 100,000 won per DABS(A), the exchange node will send 100 DABS(A) to the DABS service based on the record on the block chain. It can be determined whether it exists in the wallet of the user device (sell). Based on the record on the block, if 100 DABS(A) exist in the wallet of the DAB service user device (sell), the sale can be approved.

At this time, the selling request information (DABS(A), 100 pieces, 100,000 won) may be included in the transaction and transmitted to the verification node 420, and may be recorded on the block chain through verification of the verification node 420.

Conversely, when the DABS service user device (buy) requests to buy 100 DABS(A) at 100,000 won per DABS(A), the exchange device 430 sets the block chain for the wallet of the DABS service user device (buy). It can be determined whether there is a purchase asset to purchase 100 DABS(A) at 100,000 won based on the record. If there is a purchase asset based on the record on the block, purchase request information can be created. At this time, purchase request information (DABS(A), 100 pieces, 100,000 won) may be included in the transaction and transmitted to the verification node 420, and may be recorded on the block chain through verification of the verification node 420.

When the sell request information and the buy request information match on the block chain, a transaction may be performed and the transaction result may be transmitted to the exchange device 430, the DABS service user device (sell), and the DABS service user device (buy).

When there is information on request to sell and information to request to buy that match based on the block chain code, the transaction proceeds, and the DABS may be moved according to the transaction. When a transaction is in progress, 100 DABSs (A) stored in the wallet of the DABS service user device (sell) may be transferred to the wallet of the DABS service user device (buy). Conversely, assets (eg, fiat currency or digital assets) corresponding to 100 DABS (A) may be moved from the wallet of the DABS service user device (buy) to the wallet of the DABS service user device (sell).

That is, the transaction method according to the embodiment of the present invention may be a method of performing a transaction by actually matching the selling request information and the buying request information on the block chain, unlike the existing transaction on the ledger. Direct DABS transactions can be performed on the block chain rather than the DABS transactions on the ledger, faster than the existing verification and consensus methods by setting a separate blockchain code or through the verification and consensus method of verification nodes connected through separate channels.

As described above, a separate DABS may be issued for each asset and traded on the exchange device 630 . For example, DABS (A) for real estate A, DABS (B) for real estate B, DABS (C) for real estate C, and DABS (D) for real estate D are issued, respectively, and exchange device 630 is issued. can be traded through

7 discloses a method of distributing revenue for an asset through a blockchain.

Referring to FIG. 7 , when a profit is generated on an asset that has issued a DABS, the revenue on an asset that has issued a DABS may be distributed to the DABS service user devices 750 holding the DABS in a wallet.

If the monthly rental income for real estate A is distributed, the monthly rental income can be converted into a specific digital asset after deposit. For example, if real estate A's monthly rental income generates 100 million won, it is converted into a digital asset equivalent to 100 million, and the converted digital asset is a DABS that owns DABS(A) based on the distribution information of DABS(A). may be distributed to the service user device 750 .

For example, if the total issuance is 10,000 and DABS service user device A has 10, the amount equivalent to 1/1000 of the total amount of digital assets converted to monthly rent is the wallet of device A using DABS issuance and transaction services. can be deposited into Records of virtual currency conversion and distribution of such real estate monthly rent can be included in the transaction and recorded on the blockchain.

8 discloses a method for defending the price of DABS.

Referring to FIG. 8 , a lower price limit range of the DABS may be set. The lower price range of the DABS may be determined in consideration of the current price of the DABS and the initial sale price of the DABS.

Based on the block chain code, the lower limit of the DABS price may be determined in consideration of the current price of the DABS transmitted through the exchange device 830 and the initial sale price of the DABS.

After the lower limit price of the DABS is determined, when the price of the DABS traded in the exchange device 830 falls below the lower limit price of the DABS, a purchase for the DABS may be requested to defend the lower limit price of the DABS.

If the current price of the DABS input based on the block chain code is below the lower limit price of the DABS, the DABS service device 810 may purchase the DABS that is sold below the lower limit price through a buy order for the DABS based on the block chain code. . When the price of the DABS is equal to or greater than the lower limit price based on the block chain code, the DABS service device 810 may stop the purchase order.

The lower limit price of the DABS may be determined based on the above-described price stability. Price stability for each asset may be set. The minimum price of the DABS set as the lower limit range of price stability may be the lower limit price of the DABS. By setting the lower price limit of DABS, it is possible to invest according to the characteristics of each asset, and it can be set not to fall below a certain range based on the evaluated price of real estate. In addition, the lower limit range of the price may be additionally adjusted in consideration of additional information transmitted to an external node (eg, official land price, etc.). If, when the official land price decreases, the lower limit range of the price may be relatively wider, and conversely, if the official land price rises, the lower limit range of the price may be relatively narrower. Information on the official land price is transmitted on the blockchain network through an external node, and the lower limit range of the price can be set based on the delivered information on the official land price and the set chain code.

In FIG. 9, a method for trading for assets issued and traded as DABS is disclosed.

Referring to FIG. 9 , a DABS purchase procedure for an asset may be performed for trading an asset issued and traded as a DABS.

DABS for an asset does not grant the right to own the actual asset, but can grant the right to the operation of the asset and the profit resulting from the increase in the value of the asset. As described above, the monthly rental income of real estate A may be distributed based on DABS(A). Alternatively, an increase in the value of real estate A may lead to an increase in the value of DABS(A), and the owner of DABS(A) then sells DABS(A) according to the sale of real estate A. may have a right to

For the transfer of ownership of real estate A issued as DABS(A), a purchase may be performed for DABS(A). The DABS service device 910 may determine the purchase price for the purchase of the DABS (A) for the transfer of ownership of the real estate A. The DABS service node 910 may determine the purchase price of the DABS(A) in consideration of the current price of DABS(A), the initial price of DABS(A), the selling price of real estate A, etc. based on the block chain code.

In addition, the DABS service device 910 may also determine the purchase period of the DABS (A). The purchase period of the DABS(A) may be determined in consideration of the owner information of the DABS(A), information on the selling time of the real estate, and the like.

The DABS service providing device 910 may notify the purchase of the DABS(A) to the DABS service user device 950 that stores the DABS(A) in the wallet during the DABS(A) purchase period.

The DABS service user device 950 may sell the DABS(A) at the determined purchase price of the DABS(A), and the sales record of the DABS(A) may be included in the transaction and recorded on the blockchain.

If the DABS(A) purchase period set based on the block chain code has elapsed, or if the purchase procedure has progressed beyond the set threshold even before the DABS(A) purchase period has elapsed, the procedure for transferring ownership of real estate A may be possible. The remaining threshold number of DABSs (A) are collectively sold for a set amount, and the sold amount may be provided to the user of the DAB service user device 950 who does not directly sell the DABS (A) through the deposit procedure.

Through the above repurchase procedure, the transfer of ownership of real estate A is performed, and all DABS(A) for real estate A can be incinerated. Alternatively, according to an embodiment of the present invention, the repurchase period of the DABS (A) and the repurchase price of the DABS (A) may be determined as follows.

The repurchase period of DABS(A) includes information on the distribution information of the owner of DABS(A) and investment amount distribution information extracted based on the information on the block chain, and information on the holding tendency of the owner of DABS(A) of DABS(A). can be decided by taking into account. Information about the owner of the DABS (A) recorded on the block at the time when the repurchase is determined can be extracted. The repurchase period of DABS(A) may be longer as there are relatively many owners of small DABS(A). In addition, the repurchase period of the DABS(A) may be relatively long as the holding tendency of the DABS(A) of the owner of the DABS(A) is relatively high.

After the repurchase announcement, the repurchase result of DABS(A) through the repurchase procedure may be fed back and then used to adjust the length of the repurchase notice period. For example, if the repurchase procedure is shorter than the set period in the distribution information and investment amount distribution information of the owner of DABS(A) in the similar range, and the holding propensity information of DABS(A) of the owner of DABS(A), it will be repurchased later. The purchase period may be set to be relatively reduced. Conversely, if the repurchase procedure is longer than the set period in the distribution information and investment amount distribution information of the owner of DABS(A) in the similar range, and the holding propensity information of DABS(A) of the owner of DABS(A), the subsequent repurchase period is It may be set to be relatively increased. In this way, it may be possible to repurchase many DABS(A) as quickly as possible.

The repurchase price of DABS(A) may be determined in consideration of the existing price and the sale price of real estate A. If the price of DABS(A) converted based on the sale price of real estate A is compared with the price of DABS(A), and if the price of DABS(A) is higher or equal, the current price of DABS(A) will be re It may be the purchase price. Conversely, if the price of DABS(A) is low by comparing the price of DABS(A) converted based on the sale price of real estate A and the current price of DABS(A), the converted price of DABS(A) is the repurchase price. can be The price of DABS(A) converted based on the sale price of real estate A may not be a simple arithmetic division, but may be a price determined through a separate value calculation for DABS(A).

In addition, according to an embodiment of the present invention, the repurchase price of the DABS (A) may be set for each repurchase period. In order to repurchase DABS(A) faster, it may be set to buy at a higher price the faster you sell DABS(A). A price can be set for DABS(A) by dividing the repurchase section into a plurality of sub-repurchase sections, and in this way, owners can set to sell DABS(A) more quickly.

In FIG. 10, a method of performing a DABS transaction generated in an exchange node is disclosed.

Referring to FIG. 10 , a method for selling and buying a DABS by three DABS issuance and transaction service use devices is exemplarily disclosed. This is an example, and can be equally applied to DABS transactions of a plurality of other DABS service user devices.

The first DABS service user device 1010 sells 3 DABSs, the second DABS service user device 1020 buys 1 DABS, and the third DABS service user device 1030 buys 2 DABSs case can be assumed.

The first DABS service user device 1010 may create a sell order 1015 for three DABSs. The sell order 1015 may include seller information, sell DABS number information, sell DABS price information, and signature information of the first DABS service user device 1010 .

The second DABS service user device 1020 may generate a first buy order for two DABSs. The first purchase order may include first purchaser information (or identification information of the second DABS service user device), the first DABS number information, the first purchase price information, and signature information of the second DABS service user device.

The third DABS service user device 1030 may generate a second buy order 1035 for one DABS. Similarly, the second purchase order 1035 includes the second purchaser information (or identification information of the third DABS service user device), the second purchase DABS number information, the second purchase amount information, and the signature information of the third DABS service user device. may include

When the sell order 1015, the first buy order 1025, and the second buy order 1035 match, the exchange node sets the sell order 1015, the first buy order 1025, and the second buy order 1035. ) may generate a transaction 1050 including transaction information based on it and transmit it to the verification node. The verification node can verify the transaction and record transaction information on the block.

Transaction information includes, as input values, the number of sell DABSs included in the sell order 1015 , the first buy amount information included in the first buy order 1025 , and the second buy amount information included in the second buy order 1035 . may include.

In addition, as an output value, the transaction information includes first DABS information to be delivered to the second DABS service user device 1020 , first DABS information to be delivered to the third DABS service user device 1030 , and to be delivered to the first DABS service user device 1030 . Sales amount information according to the sale may be included.

When the verification of the transaction 1050 including the transaction information is performed or the transaction information is recorded on the block after the verification procedure, the sale amount is deposited into the wallet of the first DABS service user device 1010, and the second DABS service user The DABS may be delivered to the wallet of the device 1020 and the wallet of the third DABS service user device 1030 .

According to an embodiment of the present invention, nodes in a blockchain network may have a hierarchical structure according to limited functions. The DABS service node may be set as a first layer node, a second layer node, a third layer node, and a fourth layer node according to functions and data access rights. For example, the above-described verification node, exchange device, value evaluation device, and DABS service user device, etc., may include a first layer node, a second layer node, a third layer node, It can be divided into 4th layer nodes. A first layer node, a second layer node, a third layer node, and a fourth layer node may be classified based on a channel, a chain code, and data classification.

Specifically, the first layer node, the second layer node, and the second layer node may be connected through the first channel, and the node outside the fourth layer may be connected with the second channel. Through this, the fourth layer external node can be separated from the first layer node, the second layer node, and the third layer node, and the fourth layer node can perform limited operations on the blockchain network.

Next, the channel code A may be set to the first hierarchical node and the second hierarchical node among the first hierarchical node, the second hierarchical node, and the third hierarchical node, and the channel code B may be set to the third hierarchical node. A first layer node and a second layer node that set channel code A may share data related to channel code A, but a third layer node configured with channel code B may share data related to channel code B . Through this, the third layer node can be separated from the first layer node and the second layer node, and the third layer node can perform limited operations on the blockchain network.

Next, the private data may be set so that only the first layer node among the first layer node and the second layer node can access. In this case, the private data may be accessible only by the first layer node, and the second layer node may not be able to access it. Through this, the first layer node and the second layer node can be separated, and the second layer node can perform limited operations on the blockchain network.

Authority setting for each node according to an embodiment of the present invention may be performed by a setting node (eg, a DABS issuance and transaction service provision node). The setting node may include a communication unit implemented to communicate with an external node and a processor operatively connected to the communication unit. The processor may perform a method of setting privileges for each node.

According to an embodiment of the present invention, different data transaction rights can be set according to the channel, chain code, and data classification as described above in a limited way on the block chain.

In addition, according to an embodiment of the present invention, a limited function can be provided through a channel, and the channel can be restricted through connection of an independent channel and connection of a virtual channel. If a plurality of nodes to be bundled with the same channel can be set as separate separate channels without interference from other nodes, a limited function can be set as physically separate channels. For example, if Node A, Node B, and Node C can be connected without a separate node in the middle as nodes within the channel, they may be set as independent channels as physically separate channels.

However, if the node in the channel is connected only through the node outside the channel in the middle when it is necessary to set the same channel, there may be a problem in the security of the data transmitted through the channel. For example, if Node A, Node B, and Node C have to go through Node X, which is an out-of-channel node in the middle, in order to be connected as an in-channel node, a physically separate channel cannot be established. In this case, according to an embodiment of the present invention, even when an out-of-channel node is included in the middle, some channel section data separation encryption method for setting an independent channel may be used.

When data needs to be transmitted through an out-of-channel node in the middle, the section in which data needs to be transmitted through an out-of-channel node in the middle is set as a data separation encryption section, and data separation encryption can be performed in the data separation encryption section. have. Specifically, data transmitted from an in-channel node to an out-of-channel node may be encrypted and transferred to the next in-channel node in a bypass type. At this time, since the encryption may be performed based on the encryption key value included in the previously transmitted data after the initial encryption, it may be set so that only the node in the channel that has decrypted the previously transmitted data while continuously changing can decrypt it. There may be a plurality of data separation encryption sections, and an encryption key value applied to each of the plurality of data separation encryption sections may be different from each other. In this way, even when a node other than the channel exists in the middle, the node may be connected through a virtual independent channel.

The embodiments according to the present invention described above may be implemented in the form of program instructions that can be executed through 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 on the computer-readable recording medium may be specially designed and configured for the present invention, or may be known and available to those skilled in the art of computer software. Examples of the computer-readable recording medium include hard disks, magnetic media such as floppy disks and magnetic tapes, optical recording media such as CD-ROMs and DVDs, and magneto-optical media such as floppy disks. medium), and hardware devices specially configured to store and execute program instructions, such as ROM, RAM, flash memory, and the like.
