Description

A system for providing a content transformation function through content viewing intervention and granting ownership of the transformation function {A SYSTEM FOR PROVIDING CONTENT TRANSFORMATION CAPABILITIES THROUGH CONTENT VIEWING INTERVENTION AND GRANTING OWNERSHIP OF TRANSFORMATION CAPABILITIES}

Various embodiments of the present invention relate to a system that provides a content-related modification function while watching content. More specifically, it provides a content modification function to a plurality of users during the content consumption process, and provides a system for providing a content modification function to the modification function. It is about a system for granting ownership.

Today, the methods and subjects of content production have expanded to a greater number, but the main form of content consumption remains simple consumption. For example, web content from webtoons, web novels, and video platforms is simply consumed by the majority of consumers, but does not produce new content during the consumption process. In particular, consumers of video content accepted the information uploaded by the producer as is, and the scope of participation was limited to comments or community participation.

Meanwhile, content consumers' preference for content that allows direct communication and contribution to the content is increasing, rather than content that is delivered one-way. For example, a variety of content is being produced, such as communicating with the streamer by saying what you want to say, asking a question, or executing an event on a live stream such as YouTube streaming, Twitch streaming, or Afreeca TV. It is consumed through content consumers.

However, such content sharing and real-time participation-based content is only possible in the form of streaming content, and has the limitation that ownership of the content and profit distribution of subsequent secondary products are limited only to platform operators and content producers.

Accordingly, a content modification function is provided to the browser where the content is provided, and a part of the function is owned and traded by individual participating entities, allowing multiple users to create new secondary content directly during the content consumption process. There may be a research and development demand for the technology.

The page may include a browser extension 120 that provides extended functions. Here, the online content provision server 20 refers to a platform server that provides content requested by consumers, and may include, for example, YouTube, Naver TV, Twitch TV, or Afreeca TV, but is not limited thereto. . According to the embodiment, users can access the online content providing server 20 through the browser 110 and receive and consume various content from the online content providing server 20.

The browser 110 is software that connects the web on the Internet and may refer to application software based on a user interface using languages such as HTML (Hypertext Markup Language), CSS (Cascading Style Sheets), and JS (JavaScript). For example, the browser 110 may include Chrome, Firefox, Opera, Safari, etc.

Browser extension 120 may refer to an application program that can provide expanded information or perform functions by modifying existing source code when using the browser 110. According to one embodiment, the browser extension 120 may be an application in the form of an add-on to the browser 110 used by the consumer, and is a page displayed to the actual content consumer by modifying the source code provided by the browser 110. can be processed. For example, the browser extension 120 may allow conversion related to the content page according to the access of the user terminal 10. For a specific example, when the browser 110 is Chrome, the browser extension may be a Chrome extension (or Chrome extension). The specific description regarding the browser and browser extension described above is only an example, and the present invention is not limited thereto.

In one embodiment, the user terminal 10 may be associated with a user wishing to access at least one of the ownership proof and expansion platform management server 200 and the blockchain network 300. The user terminal 10 may issue a query or transaction to at least one of the ownership proof and expansion platform management server 200 and the blockchain network 300. In the present invention, queries can be used to query the owner of a modification function on the blockchain network 300. Transactions in the present invention can be used to perform updates (edit/change/delete/add) on data recorded on the blockchain network 300.

The user terminal 10 can transmit and receive application sources written in a programming language. For example, the user terminal 10 may generate a client application by compiling the application source. Also, for example, the generated client application may be executed after being delivered to at least one of the ownership proof and expansion platform management server 200 and the blockchain network 300.

The user terminal 10 can create a smart contract that can be operated on the blockchain network 300 using any language such as Solidity. Additionally, the user terminal 10 may create a transaction for distributing the created smart contract to the blockchain network 300.

The user terminal 10 can access the expansion platform 100 and the ownership proof and expansion platform management server 200 to perform transformations on the provided content pages, tokens issued on the blockchain network 300 and You can utilize your wallet to prove ownership of the transformations performed.

According to one embodiment, the user terminal 10 may operate as a node constituting the blockchain network 300. In this example, the user terminal 10 may implement at least one of a wallet function, a miner function, and a full blockchain data storage function. For example, if the user terminal 10 includes only a wallet function, it may operate as a node that performs transactions and validation (eg, a Simplified Payment Verification (SPV) node).

In an embodiment, the user terminal 10 is equipped with a display and can receive input from the user and provide output in any form to the user in performing content consumption, content modification, and ownership verification.

According to one embodiment, the extension platform 100 is related to the content (or on the page where the content is provided) through intervention (e.g., viewing intervention) on the browser 110 while the user terminal 10 is consuming online content. related) transformation function can be provided. Here, the transformation function may include various effects that process or expand the content, such as inserting, modifying, or deleting content desired by the owner. For example, in the process of watching video content, the user terminal 10 may use the browser extension 120 to insert an additional image into the video content at a certain point in time. For a more specific example, as shown in FIG. 3, modified content 520 can be created through an animation effect that covers the original content image 510, thereby transforming the content to provide a lively visual experience. In addition, for example, as shown in FIG. 4, at a specific playback point of the original content image 510, an image beyond the screen is inserted to create modified content 520, thereby maximizing the sense of fear in a specific situation. can be transformed. The specific description regarding the modification of the content described above is only an example, and the present invention is not limited thereto.

That is, various modified content (or expanded content) may be created by the user of the individual user terminal in response to the content. In this case, the modified content may be a secondary artifact of the content because the content modification function desired by the user has been applied. In other words, the browser extension 120 provides transformation functions related to content and allows users to produce secondary artifacts. Accordingly, it becomes possible to trade and own changeable rights to specific parts of specific content. In other words, the right to create secondary artifacts and the right to modify them can be exposed and traded.

In an embodiment, user terminals utilizing the extended platform may view various contents (e.g., videos, web novels, webtoons, community bulletin boards, streaming services, etc.) provided by a plurality of content providing servers 20 and individually related to each content. Users can be provided with transformed content to which the transformation function has been applied, and user terminals that directly access the content providing server 20 without utilizing the expansion platform 100 provide only the content provided by the existing content providing server 20. You can receive it.

In other words, the system of the present invention does not provide a content conversion function within a limited database by directly connecting to a specific application (e.g., a specific online content provision server), but rather converts the entire web content by utilizing the expansion platform 100. It can be expanded to the target of application of the function.

The blockchain network 300 according to an embodiment of the present invention may refer to a plurality of nodes operating based on blockchain technology. Here, blockchain technology is a distributed storage technology that uses a storage structure in which blocks are connected in a chain form to store data subject to management in a plurality of nodes constituting the blockchain network 300.

Data stored in block form can be shared by multiple nodes constituting the blockchain network 300.

In Figure 1, the blockchain network 300 is expressed as a separate entity, but according to an embodiment of the present invention, the blockchain network 300 is included in the ownership proof and expansion platform management server 200 (i.e. It may also be implemented as a blockchain network operating under the control of the ownership proof and expansion platform management server 200.

Depending on the implementation type, the blockchain network 300 may include a public blockchain network in which arbitrary nodes can perform consensus operations, or a private blockchain network in which only predetermined nodes can perform consensus operations. .

The consensus algorithm performed in the blockchain network 300 according to an embodiment of the present invention is: Proof of Work (PoW) algorithm, Proof of Stake (PoS) algorithm, Delegated Proof of Stake (DPoS) algorithm, and Practical Byzantine (PBFT) algorithm. Fault Tolerance) algorithm, Delegated Byzantine Fault Tolerance (DBFT) algorithm, Redundant Byzantine Fault Tolerance (RBFT) algorithm, Sieve algorithm, Tendermint algorithm, Paxos algorithm, Raft algorithm, Proof of Authority (PoA) algorithm, and/or Proof of Elapsed (PoET) Time) algorithm may be included.

In one embodiment of the present invention, nodes in the blockchain network 300 may operate by a blockchain core package according to a hierarchical structure. The hierarchical structure is: a data layer that defines the structure of data handled in the blockchain network 300 and manages the data, verifies the validity of blocks, performs mining to create blocks, and fees paid to miners during the mining process. A consensus layer responsible for processing, an execution layer that processes and executes smart contracts, a common layer that implements and manages P2P network protocols, hash functions, digital signatures, encoding, and common storage, and various applications are created, processed, and managed. May include an application layer.

According to one embodiment of the present invention, a content modification function is provided through content viewing intervention, and the integrity of the content itself is secured by using the blockchain network 300 in performing a method for granting ownership of the modification function. In addition to preventing ownership theft and loss of rights due to data forgery and falsification, it can also provide a decentralized content sharing system for the public benefit of multiple users.

Smart contracts according to embodiments of the present invention can be written in digital language to issue tokens to prove ownership of individual users for content-related modification functions and can be executed on any computing device. That is, when the code and/or function included in the smart contract is executed, token issuance according to embodiments of the present disclosure can be performed.

Smart contracts according to embodiments of the present invention are created by at least one of the following methods: creating a new smart contract, executing a function on a specific smart contract, or transmitting a token operable in the blockchain network 300. It can be executed. Additionally, smart contracts can be executed by transactions initiated by externally owned accounts or by other contracts.

A smart contract for issuing tokens to prove ownership of individual users for content-related modification functions according to embodiments of the present invention issues, for example, a Non-Fungible Token (NFT) in response to specific content. To do so, it may be stipulated that a specific execution fee be paid when executing a transaction.

The execution cost here may refer to any type of coin tradable in the blockchain network 300 or a separate form of medium (e.g., gas, etc.) that can be linked to the coin. As a non-limiting example, the default execution cost of a transaction may be set to 21,000 gas. For example, such execution costs may include the cost of processing the Elliptic Curve Digital Signature Algorithm (ECDSA) for the transaction issuer's account address, storage costs for storing transactions, and network bandwidth costs. In this way, if a specific cost is defined to be paid when executing a smart contract, malicious attacks such as intentional DDoS attacks can be prevented.

Additionally, an execution cost policy in which an entity that wants to create or execute a smart contract stakes a specific amount (coin, token, etc.) in the blockchain network and then executes the smart contract without paying additional fees. This may also be used. In this case, when staking ends, execution of the smart contract is not permitted.

A call between smart contracts to issue a token to prove an individual user's ownership of a content-related modification function according to embodiments of the present invention can be implemented using a structure called a message. For example, these messages can be generated by a contract account (CA) and passed to other contracts when calling a function. In one embodiment, messages in this case are generated and processed inside the blockchain network 300, unlike transactions that occur in externally owned accounts, so separate execution costs such as staking and gas may not be incurred. there is.

In implementing the process of issuing tokens to prove ownership of individual users for content-related modification functions according to embodiments of the present invention, the function of the smart contract is included in the transaction in the form of compiled code and synchronized through blockchain. When doing so, a smart contract can be implemented by executing a function expressed in code using the information included in the transaction as input to the function and then storing the results in a separate state.

When the content of the function and the input of the function are shared by a smart contract shared on the blockchain network 300, the integrity of the data can be guaranteed even if the result of the function is not shared separately.

In an additional embodiment, the computing devices that make up the blockchain network 300 may include a transaction storage database that changes the state of a smart contract and a smart contract database that stores the latest state of the smart contract. In this case, the smart contract of the present invention can be defined as an application (i.e., a file sharing application) that can change the state on the blockchain network 300, and the state of the smart contract is the application (i.e., a file sharing application). may be defined as a variable used in a shared application), and an input value for changing it may be included in a transaction issued from at least one of the user terminal 10 and the ownership proof and expansion platform management server 200.

In a further embodiment, the database storing the state of smart contracts may be combined with the database storing transactions to achieve high compression ratios. In addition, the database that stores the state of the smart contract can operate separately from the database that stores transactions to achieve distributed consensus and low dependency of the smart contract.

According to one embodiment of the present invention, it may include a database 400 that receives and stores events related to the history of multiple transactions of smart contracts. According to an embodiment, it is possible to inspect whether the modified content is created as a modified function is applied to specific content through the expansion platform 100 through the transaction records stored in the database 400.

Additionally, the database 400 may store modified content created as a user performs modification on content. In one embodiment, when the owner's ownership of the modification function is proven, the modified content stored in the database 400 may be reflected in the expansion platform 100, and accordingly, utilizing the expansion platform 100 Multiple users may be provided with multiple contents and modified contents related to the multiple contents. Additionally, the database 400 may store information about log data collected while a plurality of users use the expansion platform 100 to consume content.

According to an embodiment, the database 400 may store source code and content meta information provided by a plurality of content providing servers. For example, when a user terminal connects to a content provision server using the expansion platform 100, the expansion platform 100 may store source code and content meta information provided by the content provision server in a database. Here, the source code may be source code related to the original before modification through browser extension occurs. In an embodiment, content meta information may be information for identifying each piece of content. According to one embodiment, the expansion platform 100 may receive content metadata related to content watched (or consumed) by the user terminal 10 from a content provision server, and store the received content metadata in the database 400. ) can be transmitted to. Content meta information is information related to online content and may include at least one of content identification information and content creation information.

Additionally, when the ownership proof and expansion platform management server 200 receives a token modification request from the user terminal, it can confirm token ownership of the user terminal. The token modification request may include information about one or more modifications related to the content providing page and token ID information.

Specifically, the ownership proof and expansion platform management server 200 can check whether the token is owned in the wallet corresponding to the user terminal through the wallet address and token ID information of the user terminal through a smart contract. The ownership proof and expansion platform management server 200 checks whether an NFT corresponding to the content (or content page) for which a change function is to be applied to the wallet of the user terminal exists through the modification token ID included in the token modification request. You can. In other words, it is possible to check whether the user has ownership by comparing the token ID of the NFT in the wallet and the token ID included in the token modification request. For example, as a result of comparison between the token ID of the NFT in the wallet and the token ID included in the token modification request, if a corresponding NFT exists in the wallet of the user terminal (i.e., an NFT corresponding to the token ID included in the token modification request), Ownership proof and expansion platform management server 200 may determine that the user's ownership has been proven.

If ownership of the token is proven, the ownership proof and expansion platform management server 200 may allow modification to the content and generate token modification information based on the modification to the content. According to one embodiment, the modification to the content at the relevant point in time (eg, the point in time when ownership is proven) may be in an incomplete state and not reflected in the expansion platform 100. For example, at that point, content modified from a specific user is not exposed to other users through the expansion platform 100.

Specifically, when distributing the content change function or all information about the changed content on the smart contract, large amounts of data cannot be updated in real time due to the nature of the blockchain network 300, and the data within the chain cannot be updated. Corrections may require compensation (e.g. gas fees) to be paid to the miner. In order to solve this problem, the present invention utilizes a smart contract to perform ownership verification for the owner on-chain, and information on content modification is stored in an off-chain database. It can be saved in . That is, the system of the present invention can enable the transformation function to be applied through the expansion platform 100 when ownership proof of information about the transformation of content stored in the database 400 is completed through a smart contract. However, for this to happen, the transaction results on the smart contract and the data stored in the database must be synchronized in real time, and each data must be able to verify each other. In other words, the ownership proof and expansion platform management server 200 does not record information about content modification on-chain, but stores it off-chain, but stores it through on-chain and off-chain. This may be characterized by real-time synchronization.

In more detail, the ownership proof and expansion platform management server 200 may generate a hash ID based on token modification information, token ID, and page access information and store it in the database 400. Here, page access information is information about the content the user is accessing and may include information about the browser's cache or session values.

Additionally, the ownership proof and expansion platform management server 200 may generate a signature including token modification information, token ID, and hash ID and transmit a signature approval request to the wallet of the user terminal. In this case, the user terminal can approve the signature in response to the approval request.

Additionally, the ownership proof and expansion platform management server 200 may cause a token modification transaction to be issued through a smart contract in response to receiving signature approval information from the user terminal. That is, when approval for the signature is performed from the user terminal, a transaction related to token modification may be issued.

In an embodiment, the ownership proof and extension platform management server 200 may obtain an event corresponding to a token modification transaction through an event listener and perform verification based on the obtained event. Event listeners can monitor events generated when a transaction occurs in a smart contract in real time. In other words, events related to transaction issuance on the on-chain can be detected through the event listener.

The ownership proof and expansion platform management server 200 may perform verification by searching the database for data with the same hash ID as the hash ID corresponding to the event. Specifically, the ownership proof and expansion platform management server 200 receives an event occurring in a smart contract through an event listener, and verifies whether data with the same value as the hash ID stored in the database exists through this event. . In an embodiment, if there is data in the database 400 with the same hash ID as the hash ID corresponding to the event, the incomplete status value is changed to the completed status so that the content with the change applied to the management page of the extension platform 100 is displayed. You can make it exposed. In other words, the expansion platform 100 exposes the transformed content to multiple users when proof of ownership and proof of ownership related to the NFT of the transformed content and verification of the hash ID generated by the expansion platform management server 200 are performed. It can be done as much as possible.

In one embodiment, the ownership proof and expansion platform management server 200 may generate a hash ID based on token modification information, token ID, and page access information and use it as an off-chain data identifier. According to this embodiment, if a modification occurs directly on the smart contract without going through the extension platform 100, the extension platform 100 may not trust such information. This has the advantage of preventing illegal modification of content and not exposing unverified modified content.

Therefore, reliable synchronization of on-chain and off-chain can be achieved, and the advantages of off-chain, which are cheap and fast, can be had at the same time without losing the decentralization and security that are the advantages of on-chain.

Figure 5 is an example diagram for explaining a process of granting ownership of a translation function and a process of providing a content modification function related to an embodiment of the present invention.

As shown in FIG. 5, users related to content consumers can be connected to the content provision server 20 through the expansion platform 100 and can perform modifications to the content provision page. Here, the transformation function may include various effects that process or expand the content, such as inserting, modifying, or deleting content desired by the owner. For example, while watching video content, the user terminal 10 may use the browser extension 120 to insert an additional image into the video content at a certain point in time.

That is, various modified content (or expanded content) may be created by the user of the individual user terminal in response to the content. In this case, the modified content may be a secondary artifact of the content because the content modification function desired by the user has been applied. In other words, the browser extension 120 provides transformation functions related to content and allows users to produce secondary artifacts. Accordingly, it becomes possible to trade and own changeable rights to specific parts of specific content. In other words, the right to create secondary artifacts and the right to modify them can be exposed and traded.

According to one embodiment, an NFT corresponding to a content provision server (or a page where content is provided) may be issued to the blockchain network 300 through a smart contract. Here, NFT refers to a non-fungible token to prove ownership, may refer to a data unit stored in a blockchain, and may have a unique ID. In one embodiment, NFT can be used to prove ownership of the transformation function itself of the transformation content (or extended content) created as it is transformed through the transformation function in addition to the content and source code provided on the online content page. NFTs that prove ownership of each transformation function can be acquired through minting from a smart contract, or owned through sale in a secondary market that trades NFTs. In an embodiment, the NFT corresponding to the content page is issued to the blockchain network 300 and is owned by the user terminal through minting. According to the embodiment, the NFT is stored in the wallet of the user terminal, and the user can become the owner of the token. In this case, the user terminal owns an NFT related to the right to modify the content.

In one embodiment, the token holder may transmit a token modification request for modification of the content (or content page) to the ownership proof and extension platform management server 200. Here, the token modification request may include information about one or more modifications related to the content providing page and token ID information. Ownership proof and expansion platform management server 200 can verify ownership by checking whether the token is stored in the token owner's wallet through the token ID included in the token modification request received from the token owner. In other words, it is possible to check whether the user has ownership by comparing the token ID of the NFT in the wallet and the token ID included in the token modification request. For example, as a result of comparison between the token ID of the NFT in the wallet and the token ID included in the token modification request, if a corresponding NFT exists in the wallet of the user terminal (i.e., an NFT corresponding to the token ID included in the token modification request), Ownership proof and expansion platform management server 200 may determine that the user's ownership has been proven. If ownership of the token is proven, the ownership proof and expansion platform management server 200 may allow modification to the content and generate token modification information based on the modification to the content. According to one embodiment, the modification to the content at that point may be in an incomplete state and not reflected in the expansion platform 100. For example, at that point, content modified by the token owner is not exposed to other users through the expansion platform 100.

Additionally, the ownership proof and expansion platform management server 200 may generate a hash ID based on token modification information, token ID, and page access information and store it in the database 400. Here, page access information is information about the content the user is accessing and may include information about the browser's cache or session values.

Additionally, the ownership proof and expansion platform management server 200 may generate a signature including token modification information, token ID, and hash ID and transmit a signature approval request to the token owner's wallet. In this case, the token holder can approve the signature in response to the approval request.

Additionally, the ownership proof and extension platform management server 200 may cause a token modification transaction to be issued through a smart contract in response to receiving signature approval information from the token owner. That is, if the signature is approved by the token owner, a transaction related to token modification can be issued.

In an embodiment, the ownership proof and extension platform management server 200 may obtain an event corresponding to a token modification transaction through an event listener and perform verification based on the obtained event. Event listeners can monitor events generated when a transaction occurs in a smart contract in real time. In other words, events related to transaction issuance on the on-chain can be detected through event listeners.

The ownership proof and expansion platform management server 200 may perform verification by searching the database for data with the same hash ID as the hash ID corresponding to the event. Specifically, the ownership proof and expansion platform management server 200 receives an event occurring in a smart contract through an event listener, and verifies whether data with the same value as the hash ID stored in the database exists through this event. . In an embodiment, if there is data in the database 400 with the same hash ID as the hash ID corresponding to the event, the incomplete status value is changed to the completed status so that the content with the change applied to the management page of the extension platform 100 is displayed. You can make it exposed. In other words, the expansion platform 100 exposes the transformed content to multiple users when proof of ownership and proof of ownership related to the NFT of the transformed content and verification of the hash ID generated by the expansion platform management server 200 are performed. It can be done as much as possible. Accordingly, content consumers can receive not only content from the content provision server 20 through the expansion platform 100 but also converted content to which a transformation function has been applied through a specific user (i.e., token holder). In other words, the system of the present invention can provide a system in which individual participating entities can own and trade the part corresponding to the transformation function in the content through an application program (i.e., expansion platform) equipped with the transformation function of the browser in which the content is provided. . This has the advantage of going beyond the existing simple content consumption method and contributing to the creation of secondary content during content consumption, and can increase interest in content by increasing the interest of various content consumers through content expansion.

FIG. 6 illustrates an exemplary flowchart for authorizing proof of ownership and permission to grant information about a wallet of a user terminal to an extended platform management server related to an embodiment of the present invention.

According to one embodiment, the user terminal can log in to the wallet (S101). The ownership proof and expansion platform management server 200 can generate a wallet connection request signature to prove ownership, and can transmit the generated signature to the user's wallet (S103). In this case, the wallet can request approval for the signature from the user terminal (S105). The wallet may receive signature approval from the user terminal (S107), and accordingly, wallet confirmation may be approved (S109). In other words, if the user of the user terminal approves the signature, the wallet can be confirmed and ownership can be proven.

Figure 7 shows an example flowchart to explain the process of providing a modification function through ownership proof related to an embodiment of the present invention and providing content to which the modification function is applied through synchronization of on-chain and off-chain. The order of the steps shown in FIG. 7 may be changed as needed, and at least one step may be omitted or added. That is, the following steps are only an example of the present invention, and the scope of the present invention is not limited thereto.

According to one embodiment, the user terminal may transmit a token modification request to the ownership proof and expansion platform management server 200 (S201). When the ownership proof and expansion platform management server 200 receives a token modification request from the user terminal, it can confirm token ownership of the user terminal. The token modification request may include information about one or more modifications related to the content providing page and token ID information.

The ownership proof and expansion platform management server 200 can transmit the token ID and user's wallet information to the smart contract (S203). The smart contract can access the user's wallet through the user's wallet information and confirm the user's ownership through the token ID (S205). Through a smart contract, you can check whether you own a token in the wallet corresponding to the user terminal through the wallet address and token ID information of the user terminal. Specifically, you can check whether an NFT corresponding to the content (or content page) for which you want to apply the change function to the wallet of the user terminal exists through the modification token ID included in the token modification request.

If ownership is confirmed, the smart contract can transmit ownership confirmation information to the ownership proof and expansion platform management server 200 (S207).

If ownership of the token is proven, the ownership proof and expansion platform management server 200 may allow modification to the content and generate token modification information based on the modification to the content.

Additionally, the ownership proof and expansion platform management server 200 may generate a hash ID based on token modification information, token ID, and page access information (S209). Here, page access information is information about the content the user is accessing and may include information about the browser's cache or session values.

The ownership proof and expansion platform management server 200 may transmit the generated hash ID to the database 400 (S211).

The database 400 may store the hash ID transmitted from the ownership proof and expansion platform management server 200 (S213).

Additionally, the ownership proof and expansion platform management server 200 may generate a signature including token modification information, token ID, and hash ID (S215).

The ownership proof and expansion platform management server 200 may transmit signature request information related to the signature, including token modification information, token ID, and hash ID, to the wallet (S217).

In this case, the wallet may request approval for the signature from the user terminal 10 (S219).

As the user terminal 10 approves the signature (S221), a transaction event may occur in the smart contract (S223). That is, when approval for the signature is performed from the user terminal, a transaction related to token modification may be issued.

The event listener can detect transaction events that occur on the smart contract (S225). In other words, events related to transaction issuance on the on-chain can be detected through the event listener.

The event listener may refer to the database 400 to verify the generated event (S227). The event listener can perform verification by searching for data with a hash ID that is the same as the hash ID corresponding to the event that occurred in the database 400. Specifically, the ownership proof and expansion platform management server 200 receives an event occurring in a smart contract through an event listener, and verifies whether data with the same value as the hash ID stored in the database exists through this event. .

When verification is completed, the event listener may transmit a verification completion signal to the ownership proof and expansion platform management server 200 (S229).

The ownership proof and expansion platform management server 200 may generate a change application signal (S231) and transmit the generated signal to the expansion platform 100. Accordingly, modified content may be exposed to multiple users through the expansion platform 100.

Figure 8 exemplarily shows the connection structure of blocks stored in a blockchain network according to an embodiment of the present invention.

As shown in FIG. 8, blocks 1100a, 1100b, and 1100c, which are storage units in the blockchain network 300, can be connected to each other in a chain form to form a blockchain.

Blocks 1100a, 1100b, and 1100c may be composed of a block header and a transaction. The block header may include, for example, the hash value of the previous block header, the nonce value, and the hash value of the transaction group. The nonce value is a value that a node in the blockchain network 300 changes to create a block, and can be used as an input value for a specific hash function along with other values of the block header. When using a specific Nonce value, if the hash value of the block header is smaller than the predetermined difficulty value (which can be stored in the block header), the hash value for the block header can be determined. The hash value of the transaction group may refer to the root hash value of the data included in the transaction.

As shown in FIG. 8, since the block hash value of block 302 (1100a) is used as an input value to obtain the block hash value of the block header of block 302 (1100b), block 302 (1100b) and block 301 (1100a) ) can be connected to each other. Additionally, in calculating the block hash value, the hash value of the transaction group, which is the hash value representing transactions, is used as an input value, so if any forgery or alteration of a transaction occurs, the hash value of the transaction group is changed. In this way, adjacent blocks can be connected to each other, and transaction information within the block can be stored with integrity.

The transactions of blocks 1100a, 1100b, and 1100c are transaction(s) included in the block among issued transactions. When the transaction is included in the block, operations related to the transaction will be performed in the blockchain network 300. You can.

Here, A, B, C, D, E, and F may correspond to addresses within the blockchain network 300, such as externally owned accounts or wallet addresses. Additionally, Contract 1 and 2 may refer to smart contracts stored in the contract account.

As shown in FIG. 8, the transaction in block 301 (1100a) is a transaction transferring 20 Coins from A to B (Tx 1), and a transaction creating or calling smart contract 1 from C (Tx 2). may include.

Additionally, the transaction in block 302 (1100b) may include a transaction transferring 5 Coins from B to A (Tx 1), and a transaction creating or calling smart contract 2 from D (Tx 2).

Additionally, the transaction in block 303 (1100c) may include a transaction (Tx 1) transferring 10 Coins from F to E and a transaction (Tx 3) creating or calling smart contract 1 from G.

As an additional embodiment, although not shown in FIG. 8, the block headers of blocks 1100a, 1100b, and 1100c include: the hash value (ParentHash) of the parent block (previous block), the uncle block of the current block (the difficulty of the block is relatively high), hash value (UncleHash) of blocks (blocks that were not adopted as blocks due to low values), account address (Coinbase) that will receive the fee for the transaction after mining, root node hash value (Root) of the Merkle Patricia tree that collects account status information, and block Merkle tree root node hash value for all transactions (TxHash), Merkle tree root node hash value of receipts for all transactions in a block (ReceiptHash), 32-byte bloom filter information used to use log information (Bloom) , the sum of the block difficulty (Difficulty) calculated from the difficulty and timestamp of the previous block, the current block number (Number), and the maximum gas payable per block (the concept of the cost (token) used to process transactions/smart contracts) ( GasLimit), the total amount of gas used in transactions within the block (GasUsed), the initial creation time of the block (Time), other information of the block (Extra), and/or to ensure sufficient number of calculations to calculate the hash value in the proof of work. It may also include used values (MixDigest, Nonce).
