Description

A server, system and method for providing a ticket transaction service that provides a decentralized blockchain based smart contract {SERVER, SYSTEM AND METHOD FOR PROVIDING DECENTRALIZED BLOCKCHAIN BASED CONTRACT ASSIGNMENT SERVICE WITH SMART CONTRACT}

The present invention relates to a method for providing a usage rights transaction service that provides a decentralized blockchain-based smart contract, and provides a method for activating the transaction and distribution of B2B and B2C usage rights.

Transfer of bonds is the act of treating bonds as a single good and disposing of them. Transfer of bonds is when the transferor, the creditor and the transferee, change the subject of the bond, i.e., the creditor, as a legal act. At this time, the legal act is a bond from the transferor to the transferee It refers to a non-method contract with the content of the transfer itself. Therefore, with the transfer of bonds, the bonds are transferred directly and immediately from the transferor to the transferee without losing their identity. The transfer of the bond is the reason for the succession and acquisition of the bond from the perspective of the transferee, and the reason for the relative extinction from the perspective of the transferor. As a result, the transfer of the bond has the effect of changing the creditor, and the transferor of the bond has a dual status as the creditor in relation to the debtor and as a party to the transfer contract in relation to the transferee.

At this time, research and development of a method of trading products on the blockchain was conducted. In this regard, Korean Patent Publication No. 2019-0048666 (published on May 9, 2019), a prior art, includes the identifier of the seller who sells the product, By providing product information including the identifier and the price of the product, confirming the transaction information including the identifier of the buyer who purchases the product, the identifier of the product, and shipping information, and creating a transaction information block including the transaction information , Distributing the first transaction information block to a plurality of terminal devices included in the blockchain-based online product transaction and reputation management system, and creating it from a plurality of other terminal devices included in the blockchain-based online product transaction and reputation management system. The second transaction information block is received, the first transaction information block and the second transaction information block are connected to create a transaction information blockchain, and the process of verifying the validity of the transaction information blockchain is initiated.

However, the above-described method is only by placing transactions and reviews occurring in commodity transactions on a blockchain, and in fact, there is no disclosure at all to provide transactions or circulation of bonds. In the case of small business owners, the IT products they own due to lack of capital, etc., are only POS, and there is no confidence in the possibility of fulfilling their future debts to the small business owner. It is not an exaggeration to say that there is no market for purchasing and trading.

An embodiment of the present invention provides a platform for activating the transaction and distribution of usage rights, enabling even small business owners to create smart contracts well, and purchasing usage rights due to a long debt fulfillment period or lack of trust in the small business as a debtor. A decentralized blockchain that guarantees the integrity, transferability and reliability of the right to use and allows free transfer between individuals by managing ownership information and usage right information by assigning an identifier on the blockchain to induce the purchase of unwilling consumers. It is possible to provide a method of providing a usage rights transaction service that provides a base smart contract.

When selected and B2C use right is registered, a mapping unit that maps the identifier given to the provider terminal and stores it on the blockchain, and when a purchase event of the B2C use right is generated from the user terminal, based on the identifier given to the B2C use right. It includes a purchase management unit that retrieves the ownership state information and shares it to the user terminal, and registers the ownership of the B2C usage right to the user terminal when a due date payment event is generated in the purchase event to generate a bond transfer event.

Another embodiment of the present invention is a manager terminal that outputs a setting event for setting the type of at least one service product, manages to define type data of at least one service product, sets and stores the type data, and provides a provider terminal. When B2B usage rights and B2C usage rights, which are service products, are registered, the usage rights and ownership information are managed by assigning an identifier, and when there is a request for purchase or transfer of B2C usage rights from the user terminal, the purchase or transfer request is set in advance. In response to the condition data of the B2C usage right, a server providing a usage right transaction service that changes the ownership status information of the B2C usage right, and the B2C usage right using basic information and location information, and a hash code to extract the identifier of the B2C usage right, and to the extracted identifier Based on the ownership status information, it includes a user terminal that requests the purchase or transfer of a B2C use right.

In another embodiment of the present invention, when a setting event for setting the type of at least one service product occurs from a manager terminal, storing the type data of at least one service product to be defined, from a provider terminal providing a service. When a service product B2B use right is registered, the step of assigning and registering an identifier that identifies the provider terminal and the B2B use right, and any one of the type data defined by the provider terminal is selected, and when the B2C use right is registered, the provider terminal Mapping with the given identifier and storing it on the blockchain, when a purchase event of the B2C license is generated from the user terminal, the ownership state information is inquired based on the identifier given to the B2C license and shared to the user terminal And generating a bond transfer event by registering the ownership of the B2C use right as a user terminal when a due-dated payment event is generated in the purchase event.

In another embodiment of the present invention, when a setting event for setting the type of at least one service product occurs from a manager terminal, storing the type data of at least one service product to be defined, a first provider providing a service When a B2B service right, which is a service product, is registered from the terminal, and a B2C use right based on the B2B use right is registered at the second provider terminal, an identifier that identifies the first provider terminal, the second provider terminal, the B2B use right, and the B2C use right is assigned. The step of registering, mapping the identifiers given to the first and second provider terminals to the identifiers that identify the B2B and B2C licenses and storing them on the blockchain, when a purchase event of the B2C license is generated from the user terminal , The step of creating a bond transfer event by inquiring the ownership state information based on the identifier given to the B2C usage right to the user terminal and registering the ownership of the B2C usage right to the user terminal, and creating a B2C usage right in the user terminal. In the case of use, the first provider terminal includes the step of paying a price for the B2C use right used as the second provider terminal under a post-payment condition.

According to any one of the above-described problem solving means of the present invention, it activates the transaction and distribution of the right to use, provides a platform that allows even small business owners to create smart contracts well, and has a long debt fulfillment period or lack of trust in the small business as a debtor. In order to induce the purchase of consumers who are reluctant to purchase the right, ownership information and the right to use information are managed by assigning an identifier on the blockchain to ensure the integrity, transferability and reliability of the right to use, and to enable free transfer between individuals. By doing so, it is possible to fundamentally eliminate consumer distrust of small business owners and activate the market economy.

The at least one user terminal 100 may be a terminal of a user who purchases or transfers a usage right by using a web page, app page, program, or application related to a usage right transaction service that provides a decentralized blockchain-based smart contract. Here, the user terminal 100 may perform both the roles of the transferee or the transferor, and in the former case, the user terminal 100 may be a terminal of the user receiving the transfer. In addition, the user of the user terminal 100 may be a general consumer in case of a B2C use right, but may be a business entity in case of a B2B use right. In addition, the user terminal 100 may be a terminal that purchases a B2B usage right or a B2C usage right corresponding to the bond from the debtor, that is, the provider terminal 400, which is a bond issuer. Hereinafter, the purchase and transfer of the B2C use right will be described, but since the process of purchasing and transferring the B2B use right is equally applicable, the process of purchasing and transferring the B2B use right is not excluded. In addition, the user terminal 100 may correspond to at least one node constituting a block chain, and may be a terminal that completes the conclusion of a contract with a smart contract of the block chain for purchase and transfer. In addition, the user terminal 100 may be a terminal that contributes to providing computing resources or networking resources required for block generation in order to record, that is, mining, ownership status information generated in response to purchase and transfer. In addition, when the user terminal 100 transfers the right to use the bond according to the smart contract, the user terminal 100 may be a terminal that receives a corresponding payment from another user terminal 100, and an electronic wallet address to receive payment. It may be a terminal that holds the same or registers an account number. And, since the user terminal 100 corresponds to the transferor of the transfer of the bond, it can obtain the consent of the debtor for the transfer of the bond or notify it to the provider terminal 400 of the provider who is the debtor in order to perform the counter requirements for the transfer of the bond. , This can also be done automatically within the blockchain according to the implementation process of the smart contract. If, in the case of a bond with a special agreement against transfer of bonds, the bond loses transferability as an indication of the party’s intention to prohibit transfer, and if the bond is transferred to a third party in violation of the transfer ban However, if the debtor approves the transfer after receiving the transfer of the claim due to malicious intent or gross negligence, the transfer of the claim invalidated by the debtor's post-acceptance is confirmed and in effect. In this case, other agreements Unless there is no retroactive effect recognized and the effect of the transfer may occur from the time of acceptance, the B2C usage right is from the time of post-acceptance sent by the provider terminal 400, which is the debtor, (or at the time of arrival by the principle of reaching attention) to other user terminals 100 ) Can be transferred.

Here, the at least one user terminal 100 may be implemented as a computer capable of accessing a remote server or terminal through a network. Here, the computer may include, for example, a navigation system, a notebook equipped with a web browser, a desktop, a laptop, and the like.

The usage right transaction service providing server 300 may be a server providing a usage right transaction service web page, an app page, a program, or an application that provides a decentralized blockchain-based smart contract. In addition, the use right transaction service providing server 300 may be a server that defines and sets the type of bonds that can be sold or transferred, that is, the type or type of the use right. Of course, the types or types of use rights that are available for sale and transfer are not limited to those initially set and may be changed according to embodiments. And, the usage right transaction service providing server 300 receives a B2B usage right from at least one provider terminal 400 and reconfigures the B2B usage right to generate a B2C usage right, but the identifier of the provider terminal 400 and the B2B usage right It may be a server that generates a hash code using an identifier, generates a type identifier using basic information and location information in the hash code, and generates a B2C usage right including ownership information and usage right information using the type identifier. The B2C usage right generated based on each identifier and information step by step in this way can be usefully used when searching for a B2C usage right that is a bond to be transferred by another user terminal 100, that is, the transferee. That is, because the other user terminal 100 can detect the identifier of the B2C usage right in reverse by using the basic information, the location information, and the hash code. When the identifier of the B2C usage right is detected, information including ownership information and usage right information, such as a registered copy of real estate or movable property, can be inquired, and it is possible to determine whether to transfer or not. In this case, the ownership information may be ownership status information indicating ownership preservation, transfer, current owner information, etc., as in the case of a golf member, and the usage right information is how many days or how many times remain, and the amount In the case of a bond representing the amount, it may be information such as how much amount remains as the remaining amount, and until when the usage right is available. Here, the hash code is a value obtained by a hash function, and has the same meaning as terms such as hash value, hash checksum, or simply hash. In addition, the use right transaction service providing server 300 can receive the transfer condition data of the provider terminal 400 in the condition of the smart contract in order to secure the performance of the transferor before the transfer of the bonds and secure the performance of the debtor after the transfer of the bonds. have. At this time, the condition may be a suspension condition or a cancellation condition, and in the former case, the effect before the transfer of the bond is valid only when the condition is fulfilled, or in the latter case, the special agreement for prohibition of transfer becomes invalid only when the condition is fulfilled. I can. And, the use right transaction service providing server 300, when the transfer of the credit of the use right is completed, may be a server notifying the fact of the transfer of the bond to the provider terminal 400 as a debtor, and to change the ownership information and the use right information of the B2C use right It may be a server that allows mining to be performed.

FIG. 2 is a block diagram illustrating a server for providing a usage rights transaction service included in the system of FIG. 1, and FIG. 3 is a B2C among usage rights transaction services that provide a decentralized blockchain-based smart contract according to an embodiment of the present invention. A diagram showing an embodiment in which a usage right is registered, and FIG. 4 is a diagram showing an embodiment in which a B2C usage right is transferred among a usage right transaction service providing a decentralized blockchain-based smart contract according to an embodiment of the present invention to be.

Referring to FIG. 2, the use right transaction service providing server 300 includes a storage unit 310, a mapping unit 320, a purchase management unit 330, a transfer management unit 340, a type identification unit 350, and a smart contract. It may include a part 360.

The use right transaction service providing server 300 or another server (not shown) interlocked with each other according to an embodiment of the present invention includes at least one user terminal 100, at least one provider terminal 400, and at least one When transmitting a license transaction service application, program, app page, web page, etc. that provide a decentralized blockchain-based smart contract to the manager terminal 500, at least one user terminal 100 and at least one provider terminal 400 ), and at least one manager terminal 500 may install or open a usage rights transaction service application, program, app page, web page, etc. that provide a decentralized blockchain-based smart contract. In addition, a service program may be driven in at least one user terminal 100, at least one provider terminal 400, and at least one manager terminal 500 by using a script executed in a web browser. Here, the web browser is a program that enables you to use the web (WWW: world wide web) service, and refers to a program that receives and displays hypertext described in HTML (hyper text mark-up language). For example, Netscape , Explorer, chrome, etc. In addition, the application means an application on the terminal, and includes, for example, an app that is executed on a mobile terminal (smartphone).

Referring to FIG. 2, when a setting event for setting the type of at least one service product occurs from the manager terminal 500, the storage unit 310 may store type data of at least one service product to be defined. . At this time, the type of at least one service product is, for example, a gym usage ticket, a PC room usage ticket, a screen golf usage ticket, a jjimjilbang usage ticket, a hair shop usage ticket, a flying yoga usage ticket, a study cafe usage ticket, an indoor practice range usage ticket, a condo usage ticket, a manicure and It may be an eyelash extension procedure use ticket, but is not limited thereto. Here, in addition to the type set by the manager terminal 500, various types may be added automatically. For example, the administrator has defined and set A to D types of use rights, but if a large number of E to Z types of use rights are used and traded, the storage unit 310 collects and recognizes situation information through web crawling, etc. It may be automatically registered or transmitted to the manager terminal 100 to be registered.

When the B2B usage right, which is a service product, is registered from the provider terminal 400 providing the service, the mapping unit 320 may register by assigning an identifier identifying the provider terminal 400 and the B2B usage right, respectively. Hereinafter, a number of terms such as identifiers are described, which are not commonly used as identifiers for B2B usage rights, B2C usage rights, providers, types, etc., but mean that different identifiers are assigned and used. Of course, it does not exclude common use. Therefore, it will be obvious that even if the same term of the identifier is used, the identifier can be classified according to the term added in front of it. Here, the identifier may be a unique identification code or a semi-unique identification code capable of identifying an object by combining a plurality of pieces of information. And, the mapping unit 320, when any one of the type data defined from the provider terminal 400 is selected and the B2C use right is registered, maps the identifier given to the provider terminal 400 to Can be saved.

At this time, the blockchain may be implemented in public or private depending on the embodiment, and transactions between the parties are automatically performed in the form of peer-to-peer (P2P) on the computer network without the intervention of a central controller by comparing the results of multiple transaction ledgers in real time. It can include a smart contract that is executed as a. Through decentralization, it is a distributed, independent, and open common ledger management technology rather than the existing server-client structure.The ledger that recorded transaction information is distributed to the P2P network rather than the central server of a specific institution. It is a joint recording and management technology. To this end, the blockchain connects each block containing transaction information using a hash function, and a block is an elemental concept of a block chain, and each block consists of a block header, transaction information, and additional information. In order to perform new transactions through the blockchain, transactions must be collected to create a block, and a block containing the new transaction must be added to the blockchain and then shared with everyone. Blockchain requires some kind of cost from block producers in order to secure the reliability of new transactions added to the common ledger, but most of the blockchains can use the PoW (Proof of Work) method. The PoW method performs a hash function using the previous block hash and nonce value as input values, and the output value of the hash function must converge to a predetermined range of hash values. After that, the block creator's block that finds the above output value is added as a new block and shared with all participants. The PoW method is the most commonly used technology for consensus transactions until now, but since a lot of power can be consumed in the process of finding the nonce value, in order to perform a large amount of transactions in real time, another mining method, PoS (Proof of Stake) ), DPoS (Delegated Proof of Stake) may be used. PoS (Proof of Stake) is a form of proof of ownership of money, and a hash result value is calculated using stake to add a block. In PoS, the larger the stake you hold, the higher the probability of finding the block hash value, allowing you to create blocks relatively quickly. In DPoS, based on PoS, all individuals can participate in block mining, but only delegators elected by voting can sign the created block and connect new blocks to the existing blockchain. Representatives are elected after voting based on the shares held by each. Since the DPoS method does not use hash calculation in the consensus process, blocks can be generated faster than PoW and PoS methods using sundial calculations. Of course, in addition to the above-described method, various mining and distributed storage methods may be used, and it will be apparent that the method is not limited to the above.

When the purchase event of the B2C usage right is generated from the user terminal 100, the purchase management unit 330 inquires the ownership state information based on the identifier given to the B2C usage right and shares it with the user terminal 100. , When a due-dated payment event is generated in the purchase event, a bond transfer event may be generated by registering the ownership of the B2C use right to the user terminal 100. In this case, the ownership status information may be information in which items related to ownership preservation and transfer are recorded as a history log. This means that even if the ownership is changed and the owner is changed, it is transferred to the changed owner so that the history can be continuously recorded, and a reliable ledger is provided to prevent forgery or illegal use of the right to use. In this way, if a provider who is a small business owner registers the B2C usage right, the above-described information is generated within the platform to ensure integrity, so even ordinary small business owners who cannot write smart contracts on the existing blockchain can easily upload smart contracts on the blockchain. , It is possible to provide a safer license transaction service.

The above-described configuration describes a purchase process in which a B2C usage right as a bond is issued from a debtor as a provider. Through the transfer management unit 340, the transfer of bonds in which B2C usage rights are traded between individuals is described. The transfer management unit 340, when a transfer event of the B2C usage right is generated from the user terminal 100, changes the owner in the ownership status information extracted based on the identifier of the B2C usage right to the transferee of the B2C usage right, and changes the ownership transfer information. Ownership status information can be recorded as a history log. In this case, as a method for tracking changes in ownership, one-up-one-down, single source database, cumulative traceability, distributed traceability, etc. may be used, but is not limited thereto. First of all, One-up-One-Down is a method of tracking traces by maintaining only the link between the previous step and the next step when there is an actual physical event flow. This method has the advantage of being able to form traceability data with minimal effort, so it is easy to construct, and for example, GTS 1.3, which is the GS1 traceability standard, may be applied, but is not limited thereto. Second, a single source database can increase the efficiency of traceability by storing all data related to traceability in one data storage. As all data is gathered in one storage, participating entities involved in traceability If there are many, data security and monopoly issues may arise. Third, cumulative traceability is a method of implementing traceability by accumulating event data one by one as the physical data flow progresses, and can be used when the traceability route is relatively clear and security is important. Finally, in Distributed Traceability, event data is stored in a distributed manner, and only link data between each other is stored in a trusted organization, thereby enhancing both the advantages of a distributed system and the efficiency of traceability. At this time, it will be obvious that any one of the above-described ones, a combination of one or more, or other methods may be used depending on the nature, characteristics, or types of the right to use.

The purchase management unit 330 may set the payment condition as prepaid or postpaid settlement in the B2B license or B2C license registration.If the B2C license is generated based on the B2C license, which is a postpaid settlement type, if the B2C license is actually used. Only, the B2C product configurator can fulfill the debt fulfillment condition to the B2B license holder. For example, if Company A uploads the terms of payment in the B2B license list as prepaid or postpaid for B2B licenses including B2C licenses, Company A will use B2B licenses from B2B licenses in the B2B license list to form a combination of B2C licenses. By selecting, you will configure your own product and complex B2C license. At this time, if the payment condition is prepaid, the payment between A and B is made, and if the payment is postpaid, it proceeds without payment. When C purchases a B2C coupon composed by A, payment is made between A and C, and when the purchase is made, C purchases a combined B2C coupon, so that A's B2C coupon and B2C coupon are both obtained. And, if the payment condition of B's B2B license is deferred payment, when using B's B2C license owned by C, A pays B for the amount of the amount used. At this time, when each process proceeds, that is, when bonds are transferred, the transaction is recorded in the blockchain as a block is created, and accordingly, the history of bond transfer can be recorded.The difference from bond transfer is that payment and transfer of bonds are different. It is not a simultaneous transition relationship. This is because such a transaction is possible by having the specificity of a block chain, and is a unique configuration provided in an embodiment of the present invention.

In summary, in the case of deferred payment terms, when the right to use is actually used, the person who constitutes the product makes payment to the person who provided the product. When a setting event for setting the type of at least one service product occurs from the manager terminal 500, the purchase management unit 330 stores the type data of at least one service product to be defined, and provides a first service. When a service product B2B usage right is registered from the provider terminal 400(1), and a B2C usage right based on the B2B usage right is registered in the second provider terminal 400(2), the first provider terminal 400(1) , The second provider terminal 400(2), the B2B usage right and the B2C usage right are each assigned and registered with an identifier. In addition, the purchase management unit 330 maps the identifier given to the first provider terminal 400(1) and the second provider terminal 400(2) and the identifier for identifying the B2B usage right and the B2C usage right on the blockchain. Save it to. In addition, the purchase management unit 330, when a purchase event of the B2C use right is generated from the user terminal 100, inquires the ownership state information (State Info) based on the identifier given to the B2C use right to the user terminal 100. When sharing and registering the ownership of the B2C use right to the user terminal to generate a bond transfer event, and using the B2C use right in the user terminal 100, the first provider terminal 400(1) is the second provider terminal 400 ( 2) Pay the price for the B2C voucher used for) on a post-paid basis.

The type identification unit 350 generates a hash code based on an identifier that identifies the provider terminal 400 and the B2B usage right, and creates a type identifier by adding basic information and location information of the B2C usage right to the hash code. can do. If the identifier of the provider terminal 400 is AAAA and the identifier of the B2B usage right is BBBB, x may be (AAAA, BBBB) at f(x)=y, and y by the hash function f(x) As a result, a hash code is generated. The generated hash code can be generated as a type identifier by adding basic information and location information. In this case, the hash function may also be used, but is not limited thereto. Then, the identifier of the B2C use right is generated by using the type identifier and the use right information and ownership information of the B2C use right registered in the provider terminal 400. Therefore, if the basic information and location information of the B2C use right are inversely substituted into the hash function, the identifier of the B2C use right can be tracked as a result, and accordingly, the user who wants to transfer the B2C use right can search for the use right information and ownership information. They can use this information to make a transaction (transfer). In summary, the identifier of the B2C usage right may be an identifier generated by adding ownership status information and usage right status information to a type identifier. In addition, the user terminal 100 may extract the identifier of the B2C use right using basic information and location information of the B2C use right and a hash code, and query the B2C use right identified by the extracted identifier. In addition, the identifier may include any one or a combination of at least one of a two-dimensional identification code, a three-dimensional identification code, an electronic code, an electronic tag, and a biometric identification code. Here, the two-dimensional identification code may be, for example, a QR code or a barcode, but is not limited thereto. Further, the electronic tag may be an NFC tag or an RFID tag, and the electronic code may be a hash code, but is not limited thereto.

On the other hand, the condition data of the bond transfer may be received from the provider terminal 400 registered with the B2B usage right or the B2C usage right and used as input data for generating a smart contract. The smart contract unit 360 may automatically establish a bond transfer contract when there is a transaction of transfer of bonds between individuals between the user terminal 100 and the transferee terminal, when the transaction satisfies condition data. A smart contract is a software code implemented on a blockchain platform that guarantees that contracts are automatically executed for assets contained in the blockchain according to the fulfillment of the pre-imposed conditions. In other words, smart contracts are automated self-enforced agreements that combine the two processes of contract establishment and execution into one by blockchain technology. The technical concept of smart contract is that transaction records are distributed and stored, decentralized, and shared, and the duplicated ledger is operated and stored, and at the same time, it is a kind of program that automatically executes according to an event that directs the transfer of assets to the ledger. -driven program). On the other hand, smart contracts are legally required to ① have two or more parties, ② are related to the transfer of assets from one party to the other, and ③ the implementation is automatically performed, and once the contract is initiated. It is a contract concept that does not require human intervention. In this respect, a smart contract as an element of contract law is a kind of algorithmic contract, and in an algorithmic contract, one party or both parties promises to use an algorithm to determine whether or not to conclude the contract and conditions. However, smart contracts are distinguished from algorithmic contracts in that they can form DAO (Decentralized Autonomous Organization), a kind of decentralized autonomous organization. On the other hand, since smart contracts are automatically executed without human intervention, they do not value the trust of the parties. Therefore, the problem of contract default, the biggest weakness of the contract, is a kind of so-called conditional nature that is determined not by the credit of the other party, but by the fulfillment of the programmed conditions. Therefore, in smart contracts, interpreting, judging, and evaluating whether the conditions are fulfilled becomes a legally important issue, and the conditions are set by the provider terminal 400 as described above, but set by agreement with the user terminal 100 as a creditor. Does not rule out being.

Transactions of smart contracts consist of ① writing programming code, ② signing code, ③ storing the blockchain, and ④ executing the transaction. The program code executed here and its results are included in the transaction and stored in the form of a database in a block connected by a chain, so that all participants share transaction information, and the transaction details and contract details are distributed without any addition or change. ) Are stored independently of each other. Here, participants sign a contract by linking a wallet address created with public key cryptography with a blockchain and sign an electronic signature. A smart contract transaction is a computer protocol that makes it easy and convenient to execute or verify the execution of a contract on a network. These transactions can be traced, but have the irreversibility that cannot return or change the transaction record to a previous state. In this case, functions including Turing-completeness, value-awareness, blockchain-awareness, and state concept may be provided.

I can. At this time, it is necessary to register information through mining, that is, creating a block, which is mining, in the blockchain, so it also plays the role of a node of the blockchain that provides computing and networking resources to provide the resource. At this time, a hash code is generated so that the provider and the right to use can be identified, but the use right transaction service providing server 300 generates a type identifier using basic information of the B2B use right and the location information of the provider, and provides the B2C use right. Upon registration, it creates and registers an identifier of the B2C usage right based on the type identifier.

Referring to FIG. 4, when the user terminal 100(1) purchases a B2C usage right from the provider terminal 400 and then wants to transfer it to another person, the usage right transaction service providing server 300 receives an application for transfer. By previously receiving the transfer condition data from the provider terminal 400, a smart contract is created for whether transfer is feasible before transfer and under what conditions after transfer. In addition, the user terminal 100 (1) transmits a transaction (transfer) request to the usage right transaction service providing server 300, and the usage right transaction service providing server 300 transmits the information of the B2C usage right to another user terminal 100 ( 2)) to be able to search. At this time, the other user terminal (100(2)) can extract the identifier of the B2C usage right by using the hash code when inquiring the basic information and location information, and the ownership information and usage right information as the identifier of the extracted B2C usage right. You can search. After that, if the transfer condition was a certain amount of escrow payment or transfer to an e-mail address wallet, when escrow payment or transfer is made, the B2C license is automatically attributed to the other user terminal 100(2) on the blockchain, and the bond The counter requirements for transfer of ownership and transfer of bonds are implemented. Alternatively, the execution of the counter requirements may be executed by the use right transaction service providing server 300.
