Afterwards, the service providing server can check the quantity of each issued content NFT for the content NFT of the confirmed content and calculate the average value for each confirmed issued quantity.

Afterwards, the service providing server may determine the average value for each confirmed issuance quantity as the average issuance quantity, and the average issuance quantity determined in this way is the same amount as the desired transaction amount desired by the provider terminal. This may mean the average issued quantity of content NFT.

Afterwards, the service providing server can compare the average issuance quantity and the desired issuance quantity and determine whether the desired issuance quantity of the content NFT for which issuance has been requested is justified based on the comparison result (S212-2).

In other words, the service provision server does not immediately issue blockchain mainnet-based content NFTs for content based on the desired issuance quantity obtained from the provider terminal, but is the desired issuance quantity requested by the provider terminal a legitimate issuance quantity? You can carry out a decision-making process. First, the service providing server can compare the value of the average issuance quantity and the value of the desired issuance quantity to determine whether it is legitimate.

Thereafter, if the value of the average issuance quantity is less than or equal to the value of the desired issuance quantity, the service providing server may determine that the desired issuance quantity is an appropriate level judged based on the amount at which the content NFT is traded on the content NFT trading platform. In this way, if the service providing server determines that the desired issuance quantity obtained from the provider terminal is legitimate, it may determine the desired issuance quantity obtained from the provider terminal as the maximum quantity for issuance of content NFT for the content.

On the other hand, if the value of the average issuance quantity is greater than or equal to the value of the desired issuance quantity, the service providing server may determine that the desired issuance quantity is not justified as it is an appropriate level judged based on the amount at which content NFTs are traded on the content NFT trading platform. there is. At this time, if the service providing server determines that the value of the desired issuance quantity obtained from the provider terminal is not legitimate, a value corresponding to an appropriate level is provided to issue a content NFT based on the blockchain mainnet in place of the desired issuance quantity. Procedures for judgment can be performed.

However, it is not limited to this, and in another exemplary embodiment, it may be judged to be justified if the value of the average issuance quantity is greater than or equal to the value of the desired issuance quantity, and may be judged to be unjustified if the value of the average issuance quantity is less than or equal to the value of the desired issuance quantity. there is. Alternatively, legitimacy may be determined by comparing the value of the average issuance quantity and the value of the desired issuance quantity using preset standards.

In this regard, the specific process in which the service provision server determines the value corresponding to the appropriate level to issue blockchain mainnet-based content NFTs in place of the desired issuance quantity is described below with reference to Figure 7. It can be explained in more detail.

Figure 7 is a flowchart showing a method of utilizing the content NFT transaction index in a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to FIG. 7, if the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention determines that the desired issuance quantity is not legitimate, the past transaction equal to the desired transaction amount is retrieved from the database. The content NFT transaction index, which is the ratio between the issuance quantity and transaction number of each content NFT with an amount, can be calculated (S212-3).

Specifically, the service providing server can check the content NFTs in the database that have the same past transaction amount as the desired transaction amount, and then check the issued quantity of each content NFT and the number of transactions for each content NFT for the confirmed content NFTs. Afterwards, the service providing server can calculate the ratio between the issued quantity of the confirmed content NFT and the number of transactions of the content NFT, and determine the value of the calculated ratio as the content NFT transaction index of the content NFT.

In other words, the service providing server can determine the transaction value of the content NFT as the content NFT transaction index, which can indicate the active level of content NFT transactions, by calculating the ratio of the number of transactions per issued quantity of the content NFT. there is. Through this method, the service providing server can calculate the content NFT transaction index of each content NFT based on history information about the content NFT in the database.

Afterwards, the service providing server may check the issued quantity of the content NFT with the highest calculated content NFT transaction index among at least one content NFT whose issuance quantity value of the content NFT is less than or equal to the desired issuance quantity value in the database (S212-4 ).

In other words, the service providing server determines whether the value of the issued quantity of the content NFT in the database (which may mean the value of the quantity issued for a content NFT having the same past transaction amount as the desired transaction amount in the past) is less than or equal to the value of the desired issued quantity. By selecting at least one content NFT, at least one content NFT can be primarily selected among a plurality of content NFTs stored in the database. In other words, the service providing server can select a content NFT whose past transaction amount is the same as the desired transaction amount among a plurality of content NFTs issued in the past, and the value of the issuance quantity among the selected content NFTs is less than or equal to the value of the desired issuance quantity. At least one content NFT can be primarily selected.

Thereafter, the service providing server may secondarily select the content NFT with the highest calculated content NFT transaction index among the at least one selected content NFT. Afterwards, the service providing server can confirm the issued quantity of the secondary selected content NFT.

Thereafter, the service providing server may determine the issuance quantity confirmed to have the highest content NFT transaction index as the maximum quantity of NFTs that can be issued for content acquired from the provider terminal (S212-5).

In other words, the service providing server determines the issuance quantity of content NFTs with the highest content NFT transaction index confirmed through the primary and secondary selection procedures as the maximum quantity of content NFTs that can be issued for content acquired from the provider terminal. You can. Although it is difficult to satisfy the desired issuance quantity of the supplier's terminal on the platform, such a procedure may mean a procedure for reasonably determining the maximum quantity that can be issued considering the history related to the transaction of content NFTs issued on the platform.

Again, referring to Figure 4, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention provides content corresponding to the maximum quantity determined through the blockchain mainnet server linked to the service providing server. NFTs can be issued (S220).

Specifically, the service providing server can be interconnected based on communication with the blockchain mainnet server that can form or manage a blockchain mainnet-based network, and the blockchain mainnet server is a network based on the blockchain mainnet. It can refer to a device that can issue content NFTs based on the blockchain mainnet. Accordingly, the service providing server may request the issuance of a number of content NFTs corresponding to the maximum quantity of content NFTs determined based on a procedure performed in advance by the blockchain mainnet server.

Meanwhile, in response to this, the blockchain mainnet server can receive or detect a content NFT issuance request event requesting the issuance of a content NFT based on the blockchain mainnet for the content from the service providing server. Afterwards, the blockchain mainnet server can issue content NFTs for the content, and more specifically, it can issue blockchain mainnet-based content NFTs in a quantity corresponding to the maximum quantity determined by the service provision server.

At this time, if the maximum quantity is multiple, the blockchain mainnet server can set the content NFT ID given to each content NFT to a different value, and block with the content NFT ID set to a different value for each content NFT. Content NFT information, which is information about content NFT based on Chain mainnet, can be transmitted to the service provision server.

In addition, in the process of generating a content NFT ID, the blockchain mainnet server uses the content NFT ID to identify multiple content NFTs indicating the existence of different IDs for the same content and each content NFT among the multiple content NFTs. It can be created to include a serial number identifier that indicates the serial number used to distinguish or identify it.

In addition, when the blockchain mainnet server completes the issuance of content NFTs based on the blockchain mainnet for content, a preset number of master nodes and Unlike the number of master nodes, blocks generated by a preset number of random nodes can be used to store.

Specifically, a plurality of nodes managed by the blockchain mainnet server are the master node, which plays the role of a block producer capable of creating blocks, and a block observer, who is delegated the authority to create blocks. It can be divided into general nodes that play the role of observer. For example, a master node may refer to a node that can perform roles such as verifying the blockchain or creating blocks on the blockchain mainnet and receive compensation for this, and can vote on the blockchain mainnet. can be elected through

On the other hand, a random node is a node that will be used to create a block together with an elected master node, and may refer to a node randomly selected among a plurality of general nodes. For example, a random node may have the role of a randomly selected node to maintain the integrity of the overall blockchain, and may participate in creating blocks together with the elected master node to this end.

For example, the blockchain mainnet server can determine 4 random nodes by randomly selecting 4 general nodes among the 17 master nodes, which are a preset number of nodes, and the remaining general nodes excluding the master node. . Afterwards, the blockchain mainnet server can determine the order of generating blocks for the 17 master nodes and 4 random nodes to have random characteristics.

Afterwards, the blockchain mainnet server can process content NFT information, which is information about content NFTs, or information related to content, to be stored in blocks created using 21 nodes. Afterwards, the blockchain mainnet server can generate a block using 21 nodes and then arbitrarily determine 4 random nodes to be applied to the generation of the next block. In this way, the blockchain mainnet server can manage the integrity of the blockchain mainnet-based network by generating blocks using fixed master nodes and random random nodes.

Referring again to FIG. 3, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention registers the content NFT on the content NFT trading platform and sends a message-based message linked to the content NFT trading platform. You can monitor events generated by users through the service (S300).

Specifically, the service providing server is a first event related to the subscription process for the message-based service, a second event related to the payment that occurs within the message-based service, and a transaction of content NFT that occurs within the message-based service. The third event and the fourth event related to message transmission that occur within the message-based service can be monitored.

Afterwards, the service providing server can provide a blockchain mainnet-based service using a content NFT transaction platform and message-based services in response to the generated event (S400).

In this regard, the specific process of providing blockchain mainnet-based services using a content NFT transaction platform and message-based services in response to events occurring on the user terminal, which is the user's device, on the service provision server is described below. It can be explained in more detail with reference to 8 to 12.

Figure 8 is a flowchart showing a method of granting an account and wallet based on the blockchain mainnet in a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to FIG. 8, the case where the event confirmed through monitoring on the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention is the first event can be explained.

Specifically, if the event confirmed through monitoring is the first event, the service provision server creates an account based on the blockchain mainnet for the user terminal according to the subscription to the message-based service of the user terminal, which is the user's device. And a wallet can be created (S241).

At this time, when the service providing server detects a user terminal, which is a device of a user subscribing to a message-based service, it can request the blockchain mainnet server to create a blockchain mainnet-based account and wallet that the user terminal can use. there is. Accordingly, the blockchain mainnet server can receive a request from the service providing server to create a blockchain mainnet-based account and wallet that can be used by the user terminal.

Afterwards, the blockchain mainnet server can create blockchain mainnet-based accounts and wallets that can be used by user terminals. Afterwards, the blockchain mainnet server can transmit information about the blockchain mainnet-based account and wallet created for the user terminal to the service providing server. Accordingly, the service providing server can receive information about blockchain mainnet-based accounts and wallets created on the blockchain mainnet server for user terminals from the blockchain mainnet server.

Afterwards, the service providing server can generate an encrypted hash value using a preset encryption method and grant the hash value as a master key corresponding to the blockchain mainnet-based wallet created for the user terminal (S412 ).

For example, the service providing server may encrypt information about the blockchain mainnet-based account for the user terminal (for example, this may mean information related to the password among the information about the account) using a preset encryption method. A hash value can be generated as a result of encryption. Here, the service providing server has been described as generating an encrypted hash value using a preset encryption method, but it may not necessarily be limited to this. In other words, the service providing server can generate a hash value from the blockchain mainnet server, and the hash value generated in advance from the blockchain mainnet server in the process of receiving the account and wallet for the user terminal from the blockchain mainnet server. You may also receive .

At this time, the master key can be distributed and stored in a network based on the blockchain mainnet. For this purpose, if the master key is generated based on the hash value at the service providing server, the master key is transferred from the service providing server to the blockchain mainnet server. can be transmitted. On the other hand, if the master key is generated on the blockchain mainnet server, the master key can be generated on the blockchain mainnet server and then processed to be distributed and stored in the blockchain mainnet-based network.

Additionally, the process of granting a master key corresponding to a blockchain mainnet-based wallet for the user terminal from the service providing server may refer to a process of matching the blockchain mainnet-based wallet and the master key.

Afterwards, the service providing server can grant the user terminal to use the account and wallet based on the blockchain mainnet created on the content NFT trading platform through a message-based service (S413).

In other words, the service providing server can grant the user terminal an account and wallet based on the blockchain mainnet created for the user terminal, and through this, the user terminal can have an account and wallet based on the blockchain mainnet on the blockchain mainnet. The wallet may be ready for use.

Specifically, the service providing server can transmit information about the account and wallet to the user terminal so that the user terminal can use the blockchain mainnet-based account and wallet on the blockchain mainnet-based NFT trading platform. At this time, the service providing server may also transmit information about the master key generated for the user terminal to the user terminal.

In this way, the master key generated or given to the user terminal based on the hash value is used when the user terminal needs to confirm the ID or password used to use the message-based service, when the password needs to be changed, and when the password is changed. It can be used when change is necessary. At this time, the service providing server or blockchain mainnet server can process to create or grant a new master key when the master key is used by the user terminal, and the newly created master key can be used in the block after expiring the previous master key. It can be processed so that it can be distributed and stored in a chain mainnet-based network.

Below, an example of a process in which a master key is issued through a message-based service provided on a user terminal from a service providing server of a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention is shown in Figure 9. It can be explained in more detail by reference.

Figure 9 is a flowchart showing the process of issuing a master key on a user terminal through a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to Figure 9, the service providing server of a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention displays a landing screen (a) on the user terminal when a message-based service is executed on the user terminal. You can control it to be output.

Afterwards, when the landing screen (a) is closed on the user terminal, the service providing server can control the member login screen (b), where you can enter the ID and password to access the message-based service, to be displayed on the user terminal. there is. Here, the member login screen (b) may also display a user interface that allows users to sign up if they have not signed up for the message-based service.

Afterwards, the service providing server can check whether a blockchain mainnet-based wallet has been created for the user terminal when registration or login is completed for the user terminal. Afterwards, if it is confirmed that a wallet for the user terminal has not been created, the service providing server can control the wallet creation screen (c) requesting the creation of a wallet along with setting the password to be displayed on the user terminal.

Afterwards, when the service providing server receives an event requesting the creation of a wallet on the user terminal by the user, the service providing server provides information related to the account for the user terminal (e.g., password) in the process of creating a wallet for the user terminal. A master key can be generated together by encrypting the information (which may mean information such as ), and by giving the generated master key to the user terminal, the master key issuance screen (d) can be controlled to be output on the user terminal. Here, the specific process of issuing the master key may be similar or identical to that previously described.

Meanwhile, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention is a service that authenticates the identity of the user in the process of logging in to access the message-based service on the user terminal. can be provided additionally. Specifically, the service providing server can provide a service that authenticates the identity of the user terminal using a DID based on the blockchain mainnet.

For example, during the process of signing up or logging in to access a message-based service, the user terminal makes verifiable claims about the user terminal through an identity authentication server, which may mean a device from an organization that authenticates identity. You can request the issuance of a verifiable claim (VC) or a verifiable credential and receive the issued verifiable claim or verifiable credential.

To this end, the DID based on the blockchain mainnet can be stored or registered in the blockchain based on the identity authentication server of the identity authentication agency and the ID of the user's user terminal. Afterwards, the user terminal can verify the verifiable claim or verifiable credential issued by the identity authentication server through a middle node based on the blockchain mainnet.

Afterwards, the middle node based on the blockchain mainnet can transmit the result of authentication of the user's identity according to the results of blockchain verification to the service providing server. Afterwards, the service providing server can decide whether to access the service based on the result of authentication of the user's identity received from the middle node based on the blockchain mainnet. For example, if the authentication result is normal, the service providing server may allow the user terminal to access the service, and if the authentication result is not normal, the service providing server may restrict the user terminal's permission to access the service.

At this time, the middle node based on the blockchain mainnet does not hold or store information related to ID or DID, and can only verify verifiable claims or verifiable credentials received from the user terminal. Through this, the service providing server based on the blockchain mainnet can support the user or user terminal information so that it is not stored or retained by anyone except the user.

Figure 10 is a flowchart showing a method of processing a second event in a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to FIG. 10, the case where the event confirmed through monitoring on the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention is the second event can be explained.

Specifically, if the event confirmed through monitoring is a second event, the service providing server confirms the target requesting a purchase through a message-based service on the user terminal, which is the user's device, and sets up a purchase for the confirmed target. You can check the payment method (S421).

Specifically, the service provision server verifies whether the object requesting purchase from the user terminal is content or content NFT registered on an NFT trading platform using blockchain mainnet-based NFT, or a cryptocurrency that can be used on the NFT trading platform. You can. At this time, the NFT trading platform may have a pre-set payment method that can be used to make the payment required to purchase each object of purchase.

For example, the means of payment used for the object of purchase on the user terminal may correspond to one of cryptocurrency and currency issued by the blockchain mainnet server and used in the content NFT trading platform. . In other words, cryptocurrency may refer to cryptocurrency issued directly by the blockchain mainnet server, and currency may refer to currency such as cash that is generally or universally used.

Thereafter, the service providing server may process the second event by providing the user terminal with the object of purchase requested by the user terminal based on the set payment method (S422).

In this regard, the specific process of processing the second event by ensuring that the object of purchase requested by the user terminal is provided to the user terminal based on the payment method set in the service providing server will be described with reference to FIGS. 11 and 12 below. It can be explained in detail.

Figure 11 is a flowchart showing a case where a user purchases cryptocurrency on a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to FIG. 11, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention provides a password from the user terminal when the object of purchase is a cryptocurrency issued by the blockchain mainnet server. To purchase currency, payment can be requested and processed in the form of currency, which is a preset payment method (S422-11).

Specifically, the user can request the purchase of cryptocurrency issued on the content NFT trading platform for use on the content NFT trading platform using a message-based service on the user terminal. At this time, the means of payment required to purchase cryptocurrency issued on the NFT trading platform may be preset in the form of currency.

Accordingly, when the user terminal requests the purchase of cryptocurrency, the service providing server processes the user terminal to display a user interface that allows the user to pay in currency through a message-based service on the user terminal. You can. Afterwards, the user terminal can purchase cryptocurrency by paying for cryptocurrency in the form of currency.

Afterwards, the service providing server can generate ownership information about the cryptocurrency purchased by the user terminal and store the ownership information on the content NFT trading platform through the blockchain mainnet server (S422-12).

In other words, the service providing server can establish that the user terminal owns the cryptocurrency owned by the user terminal according to the generation of the cryptocurrency owned by the user terminal, and provides ownership information about the established cryptocurrency. It can be transmitted to the blockchain mainnet server.

Afterwards, the blockchain mainnet server can receive ownership information on the cryptocurrency of the user terminal received from the service providing server, and use the received ownership information in the user terminal's account or issued in advance for the user terminal. You can use a wallet to process it so that it is stored in a network based on the blockchain mainnet.

Meanwhile, if the object of purchase is a content NFT registered on the content NFT trading platform, the service provision server uses one of the cryptocurrency method and currency method, which are preset payment methods for purchasing content NFT on the user terminal. Payment can be requested and processed to be selected.

At this time, the service providing server processes the user terminal to output a user interface that allows the user to pay in either cryptocurrency or currency through a message-based service on the user terminal, as explained in advance. can do. Afterwards, the user terminal can purchase the content NFT by paying in one of the ways of cryptocurrency or currency.

However, if the payment method selected or used to purchase the content NFT at the user terminal is a currency method, the service providing server may support the purchase of the content NFT by purchasing cryptocurrency as payment for the currency.

In this regard, if the payment method selected or used by the service providing server to purchase content NFT from the user terminal is a currency method, it supports the purchase of content NFT by purchasing cryptocurrency as payment for the currency. The specific process can be described in more detail below with reference to FIG. 12.

Figure 12 is a flowchart showing a case where the payment method is a currency method in a platform using NFT based on the blockchain mainnet according to an embodiment of the present invention.

Referring to FIG. 12, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention uses the currency paid in the user terminal when the payment method selected in the user terminal is a currency method. Thus, cryptocurrency corresponding to the amount required to be paid for the purchase of content NFT can be processed to be purchased through a message-based service (S422-21)

Specifically, the service providing server can purchase cryptocurrency equal to the amount of cryptocurrency required to purchase content NFT using the currency paid at the user terminal. Afterwards, the service providing server can control the user interface so that information about the cryptocurrency purchased to purchase the content NFT can be output through a message-based service running on the user terminal.

Afterwards, the service providing server can generate information about ownership of the purchased cryptocurrency through processing and store the information about ownership on the content trading NFT trading platform through the blockchain mainnet server (S422-22).

In this regard, the specific process of generating ownership information for the purchased cryptocurrency on the service provision server and storing the ownership information on the content trading NFT trading platform through the blockchain mainnet server is to purchase cryptocurrency. It may be similar or identical to what was previously described in the process.

Afterwards, the service providing server can process the content NFT desired to be purchased from the user terminal using the cryptocurrency of the user terminal in which ownership information is registered (S422-23).

Here, when the purchase of content NFT is completed using cryptocurrency on the user terminal, the service providing server can update the history information stored in the database of the content NFT transaction platform based on the contents of the transaction that occurred for the content NFT. .

In addition, the service providing server can transmit information about the content NFT purchased from the user terminal to the blockchain mainnet server, and send information about the content NFT to an account or blockchain mainnet-based account previously issued or created for the user terminal. It can be processed so that it can be stored based on the wallet.

In other words, if the user terminal does not hold cryptocurrency or wants to pay for the content NFT in a currency other than a cryptocurrency, the service provision server provides "direct payment" that supports the purchase of content NFT in currency. This may mean that related services can be provided.

Referring again to Figure 3, if the event confirmed through monitoring in the process of providing blockchain mainnet-based services is a third event, the service providing server is related to the transaction of content NFT that occurs within the message-based service. By transmitting the changed ownership information of the content NFT to the blockchain mainnet server, a third event can be processed so that the changed ownership information is stored through the blockchain mainnet server.

In this regard, the specific process of processing the third event, which is the event of purchasing content NFT on the service provision server, may be similar or identical to that described for the process of distributing and storing ownership information in a blockchain mainnet-based network. there is.

Meanwhile, when the event confirmed through monitoring is the fourth event, the service providing server provides a user interface used to transmit a message between each user terminal, which is a device of a plurality of users subscribed to a message-based service. The fourth event can be processed by providing to each user terminal.

In other words, the service providing server can provide functions such as messengers to multiple users subscribed to the message-based service through the message-based service running on the user terminal, and through this, the service providing server can provide functions such as messengers to multiple users subscribed to the message-based service. Multiple users can send or receive messages to each other. For example, message-based services may provide functions such as messengers or social network services (SNS).

Figure 13 is a conceptual diagram showing the linkage between the service providing server of a platform using NFT based on the blockchain mainnet and the server based on the blockchain mainnet according to an embodiment of the present invention.

Referring to Figure 13, the service providing server of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention is basically linked to the blockchain mainnet server as previously described, and shows Figures 3 to 12.

Specifically, the service providing server can perform the role of an IP admin console, and the blockchain mainnet server can perform the role of providing API services and the role of an NFT explorer. As shown in FIG. 13, the role of interconnection between the service providing server and the blockchain mainnet server may be performed, but this may correspond to an embodiment of the service providing method and may not necessarily be limited thereto.

For example, the service provision server includes a content registration module, corporate membership module, personal membership module, metadata registration module, content NFT issuance management module, market interface, metadata and content approval module, content NFT issuance approval module, and IP and May include a content NFT inquiry module.

Meanwhile, the blockchain mainnet server may include a URL creation module, CDN, metadata processing module, metadata DB, content NFT issuance module, and content NFT transmission module to serve as an API service, and to serve as an NFT explorer. May include crawler, viewer, and K/V DB.

Each module or element included in the service providing server and blockchain mainnet server shown in Figure 13 may be a physical element, but may not necessarily be limited thereto, and may be distinguished based on function rather than a physical element. It may be a logical element.

According to Figure 13, the service providing server can mainly perform the role of managing the content NFT trading platform as a whole and linking between users and the content NFT trading platform. In contrast, the blockchain mainnet server is It can mainly perform roles such as issuing or processing content NFTs that can be performed in a blockchain mainnet-based network.

In this way, the service provision method of the platform using NFT based on the blockchain mainnet according to an embodiment of the present invention described with reference to FIGS. 3 to 12 includes mutual interworking between the service providing server and the blockchain mainnet server. It can be performed through transmission and reception of information.
