However, in the claims, "specific" and "related" are described to clearly understand the meaning.

1 schematically illustrates a server for issuing a call according to an embodiment of the present invention. The server 100 may include a communication unit 110 and a processor 120. The same reference numerals are used for the convenience of description and are not intended to mean that these individual devices are the same. In another embodiment of the present invention, the server may be configured differently to perform the method, or the method may be performed through the same server 100.

Specifically, server 100 is typically a computing device (eg, a device that may include components of a computer processor, memory, storage, input and output devices, other conventional computing devices; electronic communications such as routers, switches, etc.). Desired system performance using a combination of a device; an electronic information storage system such as network attached storage (NAS) and a storage area network (SAN) and computer software (ie, instructions that cause a computing device to function in a particular manner). It may be to achieve.

The communication unit 110 of such a computing device may transmit and receive a request and a response with another computing device to be interlocked. For example, the request and response may be made by the same TCP session, but are not limited thereto. For example, it may be transmitted and received as a UDP datagram.

In addition, the processor 120 of the computing device may include a hardware configuration such as a micro processing unit (MPU) or a central processing unit (CPU), a cache memory, a data bus, and the like. In addition, the operating system may further include a software configuration of an application performing a specific purpose.

First, a method of issuing a call according to an embodiment of the present invention will be described with reference to FIG. 2 through the server of FIG. 1.

When a currency issuer A including a central bank of a specific country or a currency management entity of a specific group generates and transmits a currency issuance transaction TrxA through a terminal to issue a currency (S100), the server 100 The call issuing transaction TrxA is obtained through the communication unit 110.

At this time, the currency issuance transaction (TrxA) is composed of (i) the recipient's information of the call, (ii) the issue amount of the call, (iii) the public key of the call issuer, and (iv) the private key of the call issuer. (i) the recipient's information of the call, (ii) the issue amount of the call, and (iii) the signature of the call issuer who signed the call issuer's public key. And, the receiver information of the call may be a public key of a specific user registered as a call user as information on the receiver of the issued call, and the public key of the call receiver and the public key of the call issuer are registered in advance in the server 100. In this case, the registration information may be registered with the server 100 at a corresponding time, and the registration information may be a publisher or a user having a private key and a public key, and has registered his or her public key with the server 100. Will be described in other operations. In addition, the call issuer A may have a public key of the call receiver B as information about the call receiver B in advance.

And, for example, the currency issuance transaction (TrxA) has a data format of 1. payment payment method, 2. previous transaction ID, 3. recipient, 4. issue amount, 5. issuer public key, 6. issuer signature value. However, the present invention is not limited thereto.

At this time, “1. Payment methods ”may include“ immediate payments ”and“ delayed payments, ”“ immediate payments ”allow for immediate processing of currency-related transactions, and“ deferred payments ”for currency until certain conditions are met. It may be to delay the processing of the associated transaction. For example, "delayed payment" means that if the amount for the payment is insufficient, the payment of more than the balance can be offset against the amount received after the payment to solve the liquidity problem. . However, since the issuer of the currency is the agency or equivalent party generating the new currency, “delayed payment” does not occur in the issuance of the currency, so “immediate payment” is set by default, or the payment issuance method for a currency issuing transaction. You can also include no data format. And “2. Former Transaction ID ”contains information about the balance of the issuer or user. Private transaction ID representing location information on the private blockchain database or public blockchain database where transactions previously created or traded with respect to the currency are registered. Or as a public transaction ID, the issuance of a currency may result in the creation of a new currency and thus no previous transaction ID. Also, “3. Recipient ”can be the public key (PubB) of the call recipient who will receive the issued call,“ 4. Issuance amount ”may be the amount of currency to be issued,“ 5. Issuer public key ”may be a public key (PubA) registered by the issuer,“ 6. Issuer signature value ”may be a signature value (SignPrivA (1, 2, 3, 4, 5)) of 1, 2, 3, 4, 5 signed by the currency issuer with the private key.

The processor 120 of the server 100 may then (i) call recipient information obtained through the communication unit 110, (ii) the amount of calls issued, (iii) the public key of the call issuer, and (iv) the signature of the call issuer. The validity of the currency issuance transaction (TrxA) and the currency issuer including the value is checked (S110). At this time, the processor 120 of the server 100 checks whether the data format of the call issuance transaction TrxA is valid, whether the call receiver is valid, whether the call issuer's public key is valid, and whether the call issuer's signature value is valid. To confirm the validity of the currency issuance transaction (TrxA). For example, a call receiver obtained by using the call issuer's public key against the call issuer's signature value, and by verifying that the call issuer's public key matches the value contained in the call issue transaction (TrxA). And validity of the public key of the currency issuer. In addition, by verifying the signature value of the currency issuer using the currency issuer's public key, not only the validity of the signature value of the currency issuer can be confirmed, but also the validity of the currency issuer can be verified through the currency issuer's public key.

And, if it is determined that the server 100 is valid (S110) (S210), (i) call recipient information, (ii) the amount of calls issued, (iii) the public key of the call issuer, and (iv) the signature of the call issuer. Support for registering or registering a currency issuance transaction (TrxA) containing a value in a private blockchain database (S211), and a currency representing location information on a private blockchain database of a currency issuance transaction (TrxA) registered in a private blockchain database. The issue private transaction ID (PrivTxid) may be provided to or provided to at least some of the call issuer A and the call receiver B (S212, S213). However, if the confirmation result (S110) is not valid (S220), the server 100 may provide or support the call issuer A to provide a response indicating a failure including an error message (S221). However, in the present invention, it is necessary to register in the public blockchain database 120 to be described below, and it may not be necessary to register in the private blockchain database.

On the other hand, in response to the valid verification result, the server 100, if a predetermined condition, for example, a triggering condition for registering a predetermined hash value in the public blockchain database is satisfied (S230), (i) call recipient information, ( a specific hash value (hash (TrxA)) generated by applying a hash function to a currency issuance transaction (TrxA), which includes ii) the amount of currency issued, (iii) the currency issuer's public key, and (iv) the currency issuer's signature value; By calculating at least one neighboring hash value matching a specific hash value, a representative hash value or a value obtained by processing the representative hash value is generated as a Merkle root (S231), and the representative hash value or the representative hash value that is the generated Merkle root is processed. It supports to register or register a value in the public blockchain database 120 (S232), and a value that is a representative hash value or a representative hash value processed in the public blockchain database 120. It can be supported to obtain a public call issued transaction identifier (Txid) represents the position information on the blocks of the root public database chain or obtained (S233). In this case, the server 100 may obtain an OP message corresponding to the call issuance public transaction ID (PubTxid) from the public blockchain database 200.

In addition, the operation of a specific hash value and at least one neighboring hash value may be performed by various hash functions, and the hash function may be a MD4 function, an MD5 function, a SHA-0 function, a SHA-1 function, a SHA-224 function, It will be appreciated by those skilled in the art that the present invention may include, but is not limited to, an SHA-256 function, an SHA-384 function, an SHA-512 function, and an HAS-160 function. For example, Triple SHA256 would be possible.

In this case, the server 100 may store and manage a specific hash value and at least one neighbor hash value in a predetermined data structure. Here, the data structure may vary, for example, may be a merkle tree structure. In this case, the calculation of a specific hash value and at least one neighboring hash value may be performed through a merkle tree.

That is, the server 100 may support to generate or generate a merkle tree in which a specific hash value is assigned to a specific leaf node, and if a predetermined condition is satisfied, at least one other leaf matching the specific hash value. A representative hash value or a processed value of the representative hash value, which is a Merkle root generated by calculating a hash value assigned to a node, may be registered or registered in the public blockchain database 200.

More specifically, (x1) server 100 supports (i) calculating or calculating hash values of sibling nodes of nodes to which specific hash values and (ii) specific hash values are assigned. It can support assigning or assigning a hash value to the parent node of nodes. (x2) If the parent node is the root node of the Merkle tree, the hash value assigned to the parent node becomes the representative hash value. (x3) On the other hand, if the parent node is not the root node of the Merkle tree, the server 100 repeatedly performs (x1) to (x3) by using a hash value assigned to the parent node as a specific hash value.

In addition, the server 100 supports registering or registering the hash value finally assigned to the root node of the Merkle tree as the representative hash value in the public blockchain database 200. At this time, a value obtained by processing the representative hash value may be registered. For example, a result value of performing a hex operation may be registered in the representative hash value.

Meanwhile, when the server 100 stores a specific hash value and at least one neighbor hash value in a predetermined first data structure, and then stores and manages a second data structure having the same form as the first data structure, The data structure and the second data structure may be connected in a chain form.

In particular, when the first data structure and the second data structure are Merkle trees as in the above-described example, a root value of the first data structure or a hash value of the root value may be assigned to the first leaf node of the second data structure. .

In addition, when the second data structure is generated, the integrity of the data may be more guaranteed by verifying the first data structure. The verification of the second data structure will be described later.

In addition, in the case of the first Merkle tree of at least one Merkle tree connected in a chain form, the first leaf node of the first Merkle tree may be assigned a hash value or a processed value of predetermined message data consisting of text, numbers, or symbols. have. For example, a hash value of an input message initially given by the server 100 may be assigned when generating the merkle tree.

3 and 4 illustrate an example of a merkle tree generated according to an embodiment of the present invention.

3 shows a Merkle tree with four leaf nodes. Since the illustrated Merkle tree is the first Merkle tree (tree_id = 0), it can be seen that a hash value (sha256 (coinplug_unique_message)) of predetermined message data is assigned to the h0 node which is the first leaf node. If there is a registration request for the recording data (that is, a recording request for the messenger service transmission / reception data), the server 100 generates the next leaf node of the last leaf node of the Merkle tree currently being configured to generate a specific hash value or a specific hash. Supports assigning or assigning a processed value. For example, when a new leaf node needs to be created while the value allocation is completed from the merkle tree of FIG. 3 to the second leaf node h1, the next leaf node h2 is created to process a specific hash value or a specific hash value. You can assign one value (sha256 (input2)). In addition, the server 100 may support to calculate or calculate (i) a specific hash value assigned to the h2 node and (ii) a hash value assigned to the h3 node that is a sibling node of the h2 node. The hash value for the operation value is assigned to the parent node (h23 node) of the h2 node and the h3 node. Since the parent node (h23 node) is not the root node of the Merkle tree, the server 100 may repeat the above process by using the hash value assigned to the h23 node as a specific hash value. That is, the hash value assigned to the h23 node can be used as a specific hash value, and the hash value assigned to the h23 node and the hash value assigned to the h01 node can be calculated and assigned to the parent node (h0123 node) of the h23 node and the h01 node. have. At this time, since the h0123 node is the root node of the Merkle tree, the server 100 registers or registers a value (hex (h {node_index})) of the hash value assigned to the h0123 node in the public blockchain database 200. Can support

On the other hand, the above-mentioned predetermined conditions are (i) a condition in which transactions related to a currency are generated by a predetermined number, (ii) a condition in which a predetermined time elapses, (iii) a condition in which a block is generated in a private blockchain, (iv) ) May include at least one of conditions for service characteristics. In this case, the transaction related to the currency may include issuer registration, payment settlement of a currency, user registration, and the like, which will be described later in addition to issuing a currency.

Meanwhile, for example, when a plurality of call-related transactions are obtained by the number of leaf nodes of the Merkle tree, the Merkle tree may be generated, and the root value of the Merkle tree may be registered or supported in the public blockchain database 200.

In addition, the server 100 may generate the root value of the aforementioned Merkle tree on a predetermined time unit (condition (ii) above). In this case, when a predetermined time elapses, the server 100 may generate a Merkle tree by using input values up to that time and register or register the root value of the Merkle tree in the public blockchain database 200.

However, in this case, even after a predetermined time elapses, a value may not be assigned to a sibling node of a node to which a specific hash value of the Merkle tree is assigned. If the hash value is not assigned to the sibling node of the node to which the specific hash value is assigned even though the predetermined condition is satisfied as described above, the server 100 supports to assign or allocate the predetermined hash value to the sibling node. This allows the root value of the Merkle tree to be calculated. For example, server 100 may support assigning or assigning a particular hash value to a sibling node.

The service characteristic may include at least one of cost information provided by a call issuer requesting a call issuance, time zone information at which a call issuing transaction is registered, area information at which a call issuing transaction registration service is performed, and company type information requesting a call issuing transaction registration. It can be part of it. However, the present invention is not limited to the above description and includes various condition information in which a generally accepted differential service can be provided.

On the other hand, if a new Merkle tree generation starts and a predetermined condition is satisfied in the absence of a call issuing transaction, the server 120 generates a Merkle tree in which predetermined message data is assigned to the first leaf node and the second leaf node. Or to create or register the root value of the Merkle tree or a processed value thereof in the public blockchain database 120. In this case, a two leaf node Merkle tree may be created.

Meanwhile, as described above, when the server 100 stores a specific hash value and at least one neighboring hash value in a predetermined first data structure, and then stores and manages a second data structure having the same form as the first data structure. The first data structure and the second data structure may be connected in a chain form. In particular, when the first data structure and the second data structure are Merkle trees, a root value of the first data structure or a hash value of the root value may be assigned to the first leaf node of the second data structure.

4 illustrates a Merkle tree generated as a second data structure according to an embodiment of the present invention.

Referring to FIG. 4, it can be seen that the root value hex (h0123) of the merkle tree (tree_id = 0) of FIG. 3 is assigned to the first leaf node (h4 node) of the new merkle tree (sha256 (input4)). . The present invention has an advantage of improving data integrity by easily tracking even when data is tampered with by connecting a plurality of data structures generated when a transaction occurs.

Next, a process of registering a currency issuer A will be described with reference to FIG. 5.

If the issuer registration request by the public key PubA of the call issuer A is obtained (S300), the server 100 checks whether the call issuer A is valid and when the call issuer A is valid ( In operation S310, a random nonce RN may be delivered to or supported by the call issuer A in operation S311. In addition, when the call issuer A is not valid (S320), for example, a person who steals the name of another person, the server 100 may provide or provide a response indicating the issuer verification failure to the call issuer A. It may support (S321). However, the method for determining whether the issuer A is valid is not limited thereto, and the validity of the issuer A may be determined using, for example, a time stamp. For reference, the following description will be given as an example of determining validity using a random nonce.

When the call issuer A generates the private key Prib and the public key PubA in the terminal, and transmits the public key PubA to the server 100 to register as a publisher for issuing a call, the server 100 100 checks whether the currency issuer A of the obtained public key is valid. In this case, the validity of the call issuer (A) may use a public key infrastructure (PKI) certificate or use the identification information of the call issuer (A), but is not limited thereto. For example, identification information that can verify a specific issuer through a public key-based certificate such as a public certificate or an OPSign certificate, or to prove the identity of an individual, a bank, or an organization such as a social security number, a passport, a corporate registration number, and a business registration number. You can check the currency issuer through.

Thereafter, when a random nonce signature value (SignPrivA (RN)) is obtained, which is a signature of the random nonce RN with the private key of the call issuer A (S312), the server 100 determines whether the random nonce signature value is normally signed. Validate using the public key of the currency issuer (A). That is, the server 100 checks the random nonce RN from the random nonce signature value using the call issuer's public key, and checks whether the confirmed random nonce RN matches the random nonce RN delivered to the call issuer. If it matches, it verifies that it is a valid signature.

When the signature value obtained from the call issuer A is valid (S330), the server 100 issues a publisher registration transaction (RN, SignPrivA (RN) including a random nonce, a random nonce signature value, and the call issuer's public key. , PubA) to register or register in the private blockchain database (S331), and includes a publisher registration private transaction ID (PrivTxid) indicating location information on the private blockchain database of the publisher registration transaction registered in the private blockchain database. In order to provide or provide a response indicating that the registration is successful to the call issuer (A) (S332).

However, if the signature value obtained from the call issuer A is not valid (S340), the server 100 may support or provide the call issuer A with a response including a message indicating that the signature value verification failed. There is (S341).

In addition, when the signature value of the call issuer is valid, the server 100 satisfies a predetermined condition, for example, a triggering condition for registering a predetermined hash value in the public blockchain database (S350), random nonce, and random nonce signature. A specific hash value (hash (RN, SignPrivA (RN), PubA)) generated by applying a hash function to the issuer registration transaction that includes the value and the currency issuer's public key, and at least one neighboring hash value that matches the particular hash value. Generate a representative hash value or a processed value of the representative hash value generated by calculating as a Merkle root (S351), and register the processed hash value or the representative hash value, which is the generated Merkle root, in the public blockchain database or It supports to register (S352), the public of the value processed the representative hash value or representative hash value that is the Merkle root registered in the public blockchain database 200 Published register that indicates the position information on the registered chain database 200 can be supported to obtain or acquire a public transaction ID (PubTxid) (S352). In this case, the representative hash value or the processed value of the representative hash value may be generated by the Merkle tree as described in FIG. 2. In addition, the server 100 may obtain an OP message corresponding to the issuer registration public transaction ID (PubTxid) from the public blockchain database 200.

Next, referring to Figures 6A and 6B will be described a method of payment of the currency according to an embodiment of the present invention. In the following description, a part similar to the method for issuing a currency according to an embodiment of the present invention of FIG. 2 may be understood from the description of FIG. 2 and thus the detailed description thereof will be omitted.

In order to settle the payment of the currency, when the second currency use transaction TrxC for payment of the currency is transmitted from the terminal of the specific user C from the specific user C, the server 100 transmits the communication unit 110. It receives through (S400).

At this time, the second currency use transaction (TrxC) may include (i) at least one or more unused first currency use transaction IDs, (ii) call recipient information, (iii) payment amount, and (iv) a specific user. And (v) at least one or more unused first currency usage transaction IDs that have previously been at least partially unused by the particular user's private key, (ii) call recipient information, (iii) payment amount paid, and (iv) It can contain the signature value of the specific user who signed the user's public key. In addition, at least one or more unused first currency use transaction IDs, which are previously used, are currency related transactions in which a usage amount is left with respect to payment payments received by a specific user from a currency issuer or other users. The sum of the unused amounts of all owned first currency usage transactions may be the current balance of a particular user. In addition, the call receiver information may be a public key of a call receiver that receives a call-paid currency among users registered as call users as information about a callee of a call-paid currency, and the public key of the call receiver and a specific user (C ) Is registered in the server 100 in advance, or may be registered in the server 100 at that time, if necessary, the registration information is issued by a publisher or user with a private key and a public key The key is registered in the server 100, and the description thereof will be described in another operation. In addition, the specific user C may previously have a public key of the call receiver as information on the call receiver.

And, for example, the second currency use transaction (TrxC) is 1. payment settlement method, 2. first currency use transaction ID, 3. recipient, 4. use amount, 5. balance, 6. balance owner information, 7. It may have a data format that contains the public key of a particular user, 8. The signature value of a particular user.

At this time, “1. Payment methods ”may include“ immediate payments ”and“ delayed payments, ”“ immediate payments ”allow for immediate processing of currency-related transactions, and“ deferred payments ”for currency until certain conditions are met. It may be to delay the processing of the associated transaction. For example, "delayed payment" means that if the amount for the payment is insufficient, the payment of more than the balance can be offset against the amount received after the payment to solve the liquidity problem. . And “2. First currency usage transaction ID ”includes information about the balance of a specific user C and indicates location information on a private blockchain database or a public blockchain database in which a currency usage transaction previously received with respect to the currency is registered. Private transaction ID or public transaction ID, which may be about information in a currency usage transaction, including currency usage transactions and some unused amounts paid by the issuer or other users of the currency, and owned by a particular user (C) The sum of the balances of all the first currency use transactions may be a balance currently owned by a particular user (C). Also, “3. Recipient ”may be the public key (PubB) of the recipient of the currency to receive the currency in which payment is made, and“ 4. Usage amount ”may be the amount to be paid and paid,“ 5. Balance ”is the amount remaining after payment in the balance of a specific user (C). There is no balance due to payment or it may have a negative value. Balance Owner Information ”means“ 5. In this embodiment, if there is no balance as the public key of a specific user C, there is no information, and “7. The public key of a specific user ”may be the public key of a specific user (C) who wishes to pay now,“ 8. Signature value of a specific user ”is a signature value of 1, 2, 3, 4, 5, 6, and 7 (SignPrivC (1, 2, 3, 4, 5, 6, 7) signed by a specific user C with a private key. May be).

Then, the server 100 checks the payment settlement method of the second currency use transaction with reference to the balance of the specific user (C). In this case, if the balance owned by the specific user C is greater than the payment amount, the payment is immediately checked. If the balance owned by the specific user C is less than the payment amount, the balance may be confirmed as “delayed payment”. . In addition, depending on the payment settlement method included in the second currency transaction, it can be identified as “immediate payment settlement” and “delayed payment settlement.” In particular, the payment settlement method included in the second currency usage transaction is referred to as “immediate payment settlement.” If it is entered but the balance owned by the user C is less than the payment settlement, it may be determined as "delayed payment settlement".

At this time, if the second currency use transaction (TrxC) is confirmed as "immediate payment payment" (S410), the server 100 determines whether the signature value of a specific user (C) of the second currency use transaction (TrxC) is valid If it is valid (S430), the second currency use transaction (TrxC) is registered in the private blockchain database (S431), the location information on the private blockchain database of the second currency use transaction (TrxC) registered in the private blockchain database The second call usage private transaction ID (PrivTxid) may be provided to or provided to at least some of the specific user C and the call receiver (S432). However, if the verification result is not a valid signature value (S440), the server 100 may provide or support a specific user C to provide or provide a response indicating a failure including an error message (S441).

In addition, when a predetermined condition, for example, a triggering condition is satisfied (S450), in response to a valid confirmation result, the server 100 generates a specific hash value (hash) generated by applying a hash function to the second currency use transaction TrxC. (TrxC)) and a neighbor hash value matched with a specific hash value to generate a representative hash value or a processed value of the representative hash value as a Merkle root (S451), and generates a representative hash value or a representative hash value which is the generated Merkle root. It supports to register or register the processed value in the public blockchain database (200) (S452), the public block of the processed value of the representative hash value or the representative hash value of the Merkle root registered in the public blockchain database (200) In operation S453, a second currency use public transaction ID Txid representing location information on the chain database may be obtained or acquired. In this case, the representative hash value or the processed value of the representative hash value may be generated by the Merkle tree as described in FIG. 2. In addition, the server 100 may obtain an OP message corresponding to the second call use public transaction ID (PubTxid) from the public blockchain database 200.

In contrast, if the second currency use transaction (TrxC) is confirmed as "deferred payment settlement" (S420), the server 100 determines whether the signature value of a specific user (C) of the second currency use transaction (TrxC) is valid. If it is valid (S470), the second currency use transaction (TrxC) is stored in a recording device such as a netting database, a storage unit, a memory (S471). However, if the verification result is not a valid signature value (S480), the server 100 may provide or support a specific user C to provide or provide a response indicating a failure including an error message (S481).

 At least one third currency use transaction, which is paid by at least one other user D and has a specific user C as a payee, while the second currency use transaction TrxC is stored in the storage device. When TrxD) is obtained (S472), the server 100 checks whether the acquired third currency use transaction TrxD and the second currency use transaction TrxC satisfy the offset conditions. At this time, the third currency use transaction (TrxD) may be a currency use transaction stored in the storage device as a "delayed payment" to a specific user (C), in this case, the server 100 is "delayed payment" When the stored third currency use transaction TrxD is offset, the offset may be performed in response to the second currency use transaction TrxC, and the server 100 may set the third currency use transaction as an offset condition. If (TrxD) is obtained, the offsetting process is performed, and it is determined by the offsetting process whether the balance of the specific user C has a value of "0" or more.

On the other hand, if the offset condition is not satisfied by the acquired third currency use transaction (TrxD) (S500), the server 100 stores the acquired third currency use transaction (TrxD) on the recording medium, and another third currency. Wait for the usage transaction to be acquired (S501).

In this state, when the offset condition is satisfied by the at least one third currency use transaction TrxD (S490), that is, the amount to be received by the plurality of third currency use transactions TrxD is the second currency use transaction ( TrxC) is more than the amount to be paid or the sum of the balance to be received by the plurality of third currency use transactions (TrxD) and the balance of the second specific user (C) is added to the second currency use transaction (TrxC). If more than the amount to be paid, the server 100 offsets the second currency use transaction (TrxC) and at least one third currency use transaction (TrxD). In this case, the plurality of third currency transactions (TrxD) are generated by a plurality of currency transactions generated by a specific other user, a plurality of currency transactions generated by a plurality of other users, or generated by a plurality of other users. It may be a plurality of currency transactions created by other users.

In addition, when a specific user (C) and a plurality of other users are connected to a payer and a payee of a currency use transaction of "delayed payment", respectively, to form a circular loop, the server 100 may form a specific user (C). And a "delayed payment" between multiple other users, forming a circular loop that can offset all linked currency-using transactions. Of course, if any currency usage transaction identified as "deferred payment settlement" does not satisfy the offsetting condition due to a difference in payment settlement amount from another currency usage transaction, that is, the offsetting condition of any currency usage transaction, that is, another If any currency use transaction satisfies the offset processing condition by the currency use transaction, the server 100 may offset all currency use transactions, which are "delayed payment settlement" forming a circular ring.

For example, user A creates a currency-enabled transaction A with "deferred payment" to user B, user B creates a currency-enabled transaction B with "deferred payment" to user C, and user C Deferred payment "creates a currency-enabled transaction C, and User D creates a currency-enabled transaction D with" deferred payment "to User A, allowing users A, User B, User C, and User D to When a circular ring of payees is formed, the server 100 selects currency use transaction A, currency use transaction B, currency use transaction C, and currency use transaction D generated by user A, user B, user C, and user D. Offset can be processed. Of course, the condition that the payment settlement amount in each currency use transaction that is "deferred payment settlement" must be satisfied, and if the payment settlement amounts do not match, each currency use transaction that is "delay payment settlement" If another currency use transaction satisfies the offset processing condition and each of the " delayed payment settlement " currency use transactions in the form of a purifying ring satisfies the offset processing condition, the offset processing can be performed.

In addition, the server 100 supports to register or register the offsetted second currency use transaction (TrxC) and at least one third currency use transaction (TrxD) in the private blockchain database (S491), and the private blockchain database. Second currency usage private transaction ID (PrivTxid) and third currency usage private transaction representing location information on a private blockchain database of a second currency usage transaction (TrxC) and at least one third currency usage transaction (TrxD) registered with The ID PrivTid may be provided to or provided to at least some of a specific user C, a call receiver, and at least one other user D (S492 and S493). In this case, the information stored in the recording medium, that is, the second call use transaction TrxC and the obtained at least one third call use transaction TrxD may be deleted.

In addition, the server 100 corresponds to the offset processing of the second currency use transaction TrxC and the at least one third currency use transaction TrxD, and if a predetermined condition, for example, a triggering condition is satisfied (S510), the offset process. Merkle root a representative hash value generated by calculating a specific hash value generated by applying a hash function to the second currency using transaction and at least one neighboring hash value matching the specific hash value, or a value obtained by processing the representative hash value By generating (S511), and supports to register or register in the public blockchain database (S512). In addition, the server 100 may generate a representative hash generated by calculating a specific hash value generated by applying a hash function to each of the at least one third currency use transaction processed and at least one neighboring hash value matching the specific hash value. A value or a processed value of the representative hash value may be generated as a Merkle root (S511), and may be registered or registered in the public blockchain database (S512). That is, the server 100 may support to register or register information on all the currency use transactions that have been offset in the public blockchain database 200.

In addition, the server 100 may include information indicating location information on the public blockchain database of the Merkle root corresponding to the second currency use transaction registered in the public blockchain database and the at least one third currency use transaction. It may support to acquire or obtain a 2 call usage public transaction ID (PubTxid) and at least one third call usage public transaction ID (PubTxid) (S513). In this case, the representative hash value or the processed value of the representative hash value may be generated by the Merkle tree as described in FIG. 2. In addition, the server 100 may obtain an OP message corresponding to each of the second call use public transaction ID PubTxid and the third call use public transaction ID PubTxid from the public blockchain database 200.

In addition, the process of registering a specific user who is a call user by the server 100 is as follows. The registration of a specific user also performs the same method as the registration of the call issuer in FIG. 5, and similar parts are omitted since the description in FIG. 5 can be understood.

When a user registration request by a public key of a specific user C is obtained, the server 100 checks whether the specific user C is valid, and if the specific user C is valid, randomly sets a random nonce to the specific user C. Can be delivered to or supported). In addition, when a specific user C is not valid, the server 100 may provide or support a response indicating a user confirmation failure to the specific user C.

On the other hand, if the user is a valid user, if a random nonce signature value obtained by signing a random nonce with the private key of the specific user is obtained, the server 100 verifies whether the random nonce signature value is normally signed using the specific user's public key. .

When the signature value obtained from the specific user C is valid, the server 100 registers or registers a user registration transaction including a random nonce, a random nonce signature value, and a specific user's public key in the private blockchain database. The user registration private transaction ID (PrivTxid) indicating location information on the private blockchain database of the user registration transaction registered in the private blockchain database may be provided or provided to a specific user (C).

However, if the signature value obtained from the specific user C is not valid, the server 100 may provide or provide a response indicating the signature value verification failure to the specific user 111.

In addition, when the signature value of the specific user C is valid, the server 100 may perform a user registration transaction including a random nonce, a random nonce signature value, and a specific user's public key if a predetermined condition, for example, a triggering condition is satisfied. Represents a hash value generated by calculating a hash value generated by applying a hash function and at least one neighboring hash value matching the hash value, or a value obtained by processing the hash value. And a user registration public transaction ID indicating location information on the public blockchain database of the representative hash value or the processed value of the representative hash value registered in the public blockchain database 200. PubTxid) can be obtained or supported to acquire. In this case, the representative hash value or the processed value of the representative hash value may be generated by the Merkle tree as described in FIG. 2.

Meanwhile, the call receiver B, the call user C, and the call user D described above may be commercial banks or general individuals.
