It is about a system for granting ownership.

Today, content production methods and subjects have been expanded to a large number, but the main form of content consumption remains simple consumption. For example, web contents of webtoons, web novels, and video platforms are simply consumed by the majority of consumers, and new contents are not produced in the process of consumption. In particular, consumers of video content accept the information uploaded by the producer as it is, and the scope of participation is limited to comments or community participation.

On the other hand, content consumers' preference for content that they can directly communicate with and contribute to the content is increasing rather than content that is delivered in one direction. For example, in real-time streaming such as YouTube streaming, Twitch streaming, or Afreeca TV, a variety of content is being produced, such as communicating with streamers by executing what they want to say, questions, events, etc. It is consumed through content consumers.

However, this type of content sharing and real-time participation is only possible in the form of streaming content, and the ownership of the content and the distribution of profits for subsequent secondary artifacts are limited only to platform operators and content producers.

Accordingly, by providing a content modification function to the browser where the content is provided, a part of the function is owned by an individual participating entity and made a structure that can be traded, allowing multiple users to create new secondary content directly in the process of consuming the content. R&D demand for technology may exist.

For example, the browser 110 may include chrome, firefox, opera, safari, and the like.

The browser extension 120 may refer to an application program capable of providing expanded information or performing a function by applying a modification to a previously provided source code when using the browser 110 . According to one embodiment, the browser extension 120 may be an application added to the browser 110 used by consumers, and a page displayed to actual content consumers by modifying the source code provided by the browser 110. can be processed. For example, the browser extension 120 may allow conversion related to a 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 program). The specific description related to 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 who wants to access at least one of the proof of ownership and extension 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 proof of ownership and expansion platform management server 200 and the blockchain network 300 . In the present invention, the query can be used to query the owner of the modification function on the blockchain network 300. Transactions in the present invention can be used to update (modify/change/delete/add) data recorded on the blockchain network 300.

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

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

The user terminal 10 may access the extension platform 100 and the ownership proof and extension platform management server 200 to perform transformation on the provided content page, and the token issued on the blockchain network 300 and The wallet can be utilized to prove ownership of the transformation 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, when the user terminal 10 includes only a wallet function, it may operate as a node (eg, a simplified payment verification (SPV) node) that performs transactions and validation.

In an embodiment, the user terminal 10 has a display, so that it can receive user input and provide any type of output to the user in performing content consumption, content modification, and ownership verification.

According to an embodiment, the extension platform 100 is related to the content (or to a page where the content is provided) through intervention (eg, viewing intervention) on the browser 110 in the process of the user terminal 10 consuming online content. related) transformation function can be provided. Here, the transformation function may include various effects for processing or expanding content, such as inserting, modifying, or deleting content desired by the owner. For example, while viewing video content, the user terminal 10 may insert an additional image into the corresponding video content at a specific point in time using the browser extension 120 . For a more specific example, as shown in FIG. 3 , the transformed content 520 may be generated through an animation effect covering the original content image 510 to transform the content to give a lively visual experience. In addition, for example, as shown in FIG. 4, at a specific playback time of the original content video 510, an image that exceeds the screen is inserted to create the transformed content 520 so that the feeling of fear is maximized in a specific situation. can transform. The specific description related to the modification of the above content is only an example, and the present invention is not limited thereto.

That is, various modified contents (or expanded contents) may be created corresponding to the contents by users of individual user terminals. In this case, since the transformed content is applied with a function of transforming the content desired by the user, it may correspond to a secondary artifact for the content. In other words, the browser extension 120 provides a modification function related to content so that the user can produce secondary artifacts. Accordingly, it becomes possible to trade and own changeable rights to a specific part of a specific content. That is, the right to create secondary artifacts and the right to modify can be exposed and traded.

In the embodiment, user terminals utilizing the extended platform are various contents provided by the plurality of content providing servers 20 (eg, videos, web novels, webtoons, community bulletin boards, streaming services, etc.) and individual contents in relation to each content. A user can receive modified content to which a modification function is applied, and user terminals that directly access the content providing server 20 without utilizing the extension platform 100 provide only the content provided by the existing content providing server 20. can receive

That is, the system of the present invention does not provide a content conversion function in a limited database by directly connecting to a specific application program (eg, a specific online content providing server), but converts entire web content by utilizing the extension platform 100. It can be extended to the application target of the function.

The blockchain network 300 according to an embodiment of the present invention may mean a plurality of nodes that operate based on blockchain technology. Here, the blockchain technology is a distributed storage technology that stores data to be managed in a plurality of nodes constituting the blockchain network 300 by using a storage structure in which blocks are connected in a chain form.

The blockchain network 300 may store the transaction transferred from at least one of the user terminal 10 and the proof of ownership and extension platform management server 200 in block form based on a predetermined consensus algorithm. Data stored in block form can be shared by a plurality of nodes constituting the blockchain network 300.

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

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

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

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 by the blockchain network 300 and manages the data; performs mining to verify block validity and create blocks; and fees paid to miners during the mining process. A consensus layer in charge of 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 a common layer that creates, processes, and manages various applications. It may include an application layer.

According to an embodiment of the present invention, the 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, it is possible to prevent theft of ownership and loss of rights due to data forgery, and to provide a decentralized content sharing system according to the public interest of multiple users.

A smart contract according to embodiments of the present invention can be written in a digital language for issuing a token to prove ownership of an individual user for a modification function related to content and executed on any computing device. That is, when codes and/or functions included in the smart contract are executed, token issuance according to embodiments of the present disclosure may be performed.

A smart contract according to embodiments of the present invention is a method of generating a new smart contract, a method of executing a function on a specific smart contract, or a method of transmitting a token operable in the blockchain network 300 by at least one of can be executed In addition, smart contracts can be executed by transactions initiated by externally owned accounts or by other contracts.

A smart contract for issuing a token for proving ownership of an individual user for a modification function related to content according to embodiments of the present invention issues, for example, a non-fungible token (NFT) in response to specific content. To do this, it may be stipulated to pay a specific execution cost when executing a transaction.

The execution cost herein may mean any type of coin transactable in the blockchain network 300 or another type of medium that can be interlocked with the coin (eg, gas). As a non-limiting example, the default execution cost of a transaction may be set at 21,000 gas. For example, such an execution cost may include a cost for processing an Elliptic Curve Digital Signature Algorithm (ECDSA) for the account address of the transaction issuer, a storage cost for storing the transaction, and a network bandwidth cost. In this way, if it is defined to pay a specific cost when executing a smart contract, malicious attacks such as intentional DDoS attacks can be prevented.

In addition, 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. may be used. In this case, when staking ends, execution of the smart contract is not allowed.

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

In implementing the process of issuing a token to prove the ownership of an individual user for a modification function related to content 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 the blockchain. When doing so, a smart contract can be implemented in such a way that the information included in the transaction is used as the input of the function, the function expressed in code is executed, and the result is stored 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 constituting the blockchain network 300 may include a transaction storage database for changing the state of the smart contract and a smart contract database for storing the latest state of the smart contract. In this case, the smart contract of the present invention can be defined as an application that can change the state on the blockchain network 300 (i.e., a file sharing application), and the state of the smart contract can be defined as a corresponding application (i.e., a file sharing application). It 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 extension platform management server 200.

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

According to an embodiment of the present invention, it may include a database 400 for receiving and storing events related to multiple transaction occurrence details of smart contracts. According to the embodiment, it is possible to check whether the modified content is generated as a modified function is applied to specific content through the extension platform 100 through transaction records stored in the database 400 .

In addition, the database 400 may store modified content generated as a user transforms the content. In one embodiment, when the owner's ownership of the modification function is proved, the modified content stored in the database 400 may be reflected in the extension platform 100, and accordingly, the extension platform 100 is utilized. A plurality of users may be provided with a plurality of contents and modified contents related to the plurality of contents. In addition, the database 400 may store information about log data collected while a plurality of users for consuming content use the extension platform 100 .

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

In addition, when the ownership proof and extended platform management server 200 receives a token modification request from the user terminal, it may check ownership of the token 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 proof of ownership and extension platform management server 200 may check whether the token is owned by the wallet corresponding to the user terminal through the wallet address and token ID information of the user terminal through a smart contract. The proof of ownership and extension platform management server 200 checks whether there is an NFT corresponding to the content (or content page) to which the change function is to be applied to the wallet of the user terminal through the correction token ID included in the token correction request. can That is, by comparing the token ID of the NFT in the wallet with the token ID included in the token modification request, it is possible to determine whether the user has ownership. 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 there is a corresponding NFT in the wallet of the user terminal (ie, an NFT corresponding to the token ID included in the token modification request), Ownership proof and extension platform management server 200 may determine that the ownership of the corresponding user is proven.

Proof of ownership and extension platform management server 200, when ownership of the token is proved, allows modification of the content, and may generate token modification information based on the modification of the content. According to one embodiment, the modification to the content at that time (eg, the time of proof of ownership) may be characterized in that it is not reflected in the extension platform 100 in an incomplete state. For example, at that time, content modified by a specific user is not exposed to other users through the extension platform 100 .

Specifically, when distributing all information on the content change function or 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 in the chain It may be necessary to pay a reward (e.g. gas fee) to the miner for the correction. In order to solve this problem, the present invention utilizes a smart contract to perform proof of ownership for the owner on-chain, and the information on the modification of the content is stored in an off-chain database. can be stored in That is, the system of the present invention can apply a modification function through the extension platform 100 when proof of ownership is completed through a smart contract to information about modification of contents stored in the database 400. However, for this, the result of the transaction 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. That is, the proof of ownership and extension platform management server 200 does not record information about content modification on-chain, but stores it through off-chain, but on-chain and off-chain. It may be characterized in that it is synchronized in real time.

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

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

In addition, the proof of ownership 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 a user terminal. That is, when approval of the signature is performed from the user terminal, a transaction related to token modification may be issued.

In an embodiment, the proof of ownership and extension platform management server 200 may acquire 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 transactions occur in smart contracts in real time. That is, events related to transaction issuance on-chain can be detected through event listeners.

The proof of ownership and extension platform management server 200 may perform verification by searching for data having the same hash ID as the hash ID corresponding to the event in the database. Specifically, the proof of ownership and extension platform management server 200 receives an event generated in the smart contract through an event listener, and verifies whether data having the same value as the hash ID stored in the database exists through this event. . In the embodiment, if data having the same hash ID as the hash ID corresponding to the event exists in the database 400, the incomplete status value is changed to the complete status so that the changed content is applied to the management page of the extension platform 100. can be exposed. In other words, the extension platform 100 exposes the modified content to a number of users when proof of ownership and proof of ownership related to the NFT of modified content and verification of the hash ID generated by the extension platform management server 200 are performed. can be made

In one embodiment, the proof of ownership and extension platform management server 200 generates a hash ID based on token modification information, token ID, and page access information, and can use it as an off-chain data identifier. According to this embodiment, when 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 being able to prevent illegal modification of contents and not exposing unverified modified contents.

Therefore, reliable synchronization between on-chain and off-chain can be possible, and the cheap and fast advantages of off-chain can be obtained simultaneously without losing decentralization and security, which are advantages of on-chain.

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

As shown in FIG. 5 , users related to content consumers may be connected to the content providing server 20 through the extension platform 100 and may perform transformation on the content providing page. Here, the transformation function may include various effects for processing or expanding content, such as inserting, modifying, or deleting content desired by the owner. For example, while viewing video content, the user terminal 10 may insert an additional image into the corresponding video content at a specific point in time using the browser extension 120 .

That is, various modified contents (or expanded contents) may be created corresponding to the contents by users of individual user terminals. In this case, since the transformed content is applied with a function of transforming the content desired by the user, it may correspond to a secondary artifact for the content. In other words, the browser extension 120 provides a modification function related to content so that the user can produce secondary artifacts. Accordingly, it becomes possible to trade and own changeable rights to a specific part of a specific content. That is, the right to create secondary artifacts and the right to modify can be exposed and traded.

According to one embodiment, an NFT corresponding to a content providing 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 for proof of ownership, may mean a unit of data stored in a blockchain, and may have a unique ID. In one embodiment, the NFT can be used to prove ownership of the modification function itself of the modified content (or extended content) generated as it is modified through the modification 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 trading in a secondary market where NFTs are traded. In the 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 owner of the token may be. In this case, the user terminal will possess the 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 proof of ownership 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. The proof of ownership and extension platform management server 200 may verify ownership by checking whether the token is stored in the wallet of the corresponding token owner through the token ID included in the token modification request received from the token owner. That is, by comparing the token ID of the NFT in the wallet with the token ID included in the token modification request, it is possible to determine whether the user has ownership. 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 there is a corresponding NFT in the wallet of the user terminal (ie, an NFT corresponding to the token ID included in the token modification request), Ownership proof and extension platform management server 200 may determine that the ownership of the corresponding user is proven. Proof of ownership and extension platform management server 200, when ownership of the token is proved, allows modification of the content, and may generate token modification information based on the modification of the content. According to one embodiment, the modification to the content at that time may be characterized in that it is in an incomplete state and is not reflected in the extension platform 100 . For example, at that point in time, modified content from the token holder is not exposed to other users through the extension platform 100 .

In addition, the ownership proof and extended 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, the page access information is information about content that a user is accessing, and may include information about a cache of a browser or a session value.

In addition, the proof of ownership and extension platform management server 200 may generate a signature including token modification information, a token ID, and a 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 authorization request.

In addition, the proof of ownership and extension platform management server 200 may cause a token modification transaction to be issued through a smart contract in response to receiving signature authorization information from the token holder. That is, when approval of the signature is performed from the token holder, a transaction related to token modification may be issued.

In an embodiment, the proof of ownership and extension platform management server 200 may acquire 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 transactions occur in smart contracts in real time. That is, events related to transaction issuance on the chain can be detected through event listeners.

The proof of ownership and extension platform management server 200 may perform verification by searching for data having the same hash ID as the hash ID corresponding to the event in the database. Specifically, the proof of ownership and extension platform management server 200 receives an event generated in the smart contract through an event listener, and verifies whether data having the same value as the hash ID stored in the database exists through this event. . In the embodiment, if data having the same hash ID as the hash ID corresponding to the event exists in the database 400, the incomplete status value is changed to the complete status so that the changed content is applied to the management page of the extension platform 100. can be exposed. In other words, the extension platform 100 exposes the modified content to a number of users when proof of ownership and proof of ownership related to the NFT of modified content and verification of the hash ID generated by the extension platform management server 200 are performed. can be made Accordingly, content consumers can receive not only content from the content providing server 20 through the extension platform 100, but also converted content to which a modification function is applied through a specific user (ie, a token owner). That is, the system of the present invention can provide a system in which individual participants can own and trade the part corresponding to the transformation function in the content through an application program (ie, an extension platform) having a transformation function of the browser in which the content is provided. . This has the advantage of going beyond the conventional simple content consumption method, contributing to secondary content generation during content consumption, and improving interest in content by increasing the interest of various content consumers through content expansion.

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

According to one embodiment, the user terminal may log in to the wallet (S101). Proof of ownership and extension platform management server 200 may generate a wallet connection request signature for proof of ownership, and may transmit the generated signature to the user's wallet (S103). In this case, the wallet may request approval of 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). That is, when the user of the user terminal approves the signature, the confirmation is approved in the wallet so that ownership can be proven.

7 is an exemplary flowchart for explaining a process of providing a modification function through proof of ownership related to an embodiment of the present invention and providing content to which the modification function is applied through on-chain and off-chain synchronization. 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 one embodiment 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 proof of ownership and extension platform management server 200 (S201). Proof of ownership and extension platform management server 200, when receiving a token modification request from the user terminal, can check the ownership of the token 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 proof of ownership and extension platform management server 200 may 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 can verify the user's ownership through the token ID (S205). Through the smart contract, it is possible to check whether the token is owned by the wallet corresponding to the user terminal through the wallet address and token ID information of the user terminal. Specifically, it is possible to check whether an NFT corresponding to the content (or content page) to which the change function is to be applied exists in the wallet of the user terminal through the correction token ID included in the token correction request.

If ownership is confirmed, the smart contract may transmit ownership verification information to the proof of ownership and extended platform management server 200 (S207).

Proof of ownership and extension platform management server 200, when ownership of the token is proved, allows modification of the content, and may generate token modification information based on the modification of the content.

In addition, the ownership proof and extended platform management server 200 may generate a hash ID based on token modification information, token ID, and page access information (S209). Here, the page access information is information about content that a user is accessing, and may include information about a cache of a browser or a session value.

Ownership proof and extension platform management server 200 may transmit the generated hash ID to the database 400 (S211).

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

In addition, the proof of ownership and extension platform management server 200 may generate a signature including token modification information, a token ID, and a hash ID (S215).

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

In this case, the wallet may request approval of 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 of the signature is performed from the user terminal, a transaction related to token modification may be issued.

The event listener can detect a transaction event that has occurred on the smart contract (S225). That is, events related to issuing transactions on the chain can be detected through event listeners.

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

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

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

8 illustratively illustrates a connection structure of blocks stored in a blockchain network according to an embodiment of the present invention.

Blocks 1100a, 1100b, and 1100c may include block headers and transactions. The block header may include, for example, a hash value of a previous block header, a nonce value, and a hash value of a 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 of a specific hash function together with other values of the block header. When a specific Nonce value is used, if the hash value of the block header is smaller than a predetermined difficulty value (which can be stored in the block header), the hash value for the corresponding block header may be determined. The hash value of the transaction group may mean the root hash value of 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. In addition, in obtaining a block hash value, since the hash value of a transaction group, which is a hash value representing transactions, is used as an input value, the hash value of the transaction group is changed when any forgery or falsification of the transaction occurs. In this way, adjacent blocks can be connected to each other, and information of transactions within a block can be stored with integrity.

The transactions of the blocks 1100a, 1100b, and 1100c are transaction(s) included in the block among the issued transactions, and if the transaction is included in the block, an operation related to the transaction will be performed in the blockchain network 300. 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. In addition, Contracts 1 and 2 may refer to smart contracts stored in a contract account.

As shown in FIG. 8, the transaction in block 301 (1100a) is a transaction to transfer 20 coins from A to B (Tx 1), and a transaction to create or call smart contract 1 from C (Tx 2). can include

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

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

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