Internet search is mostly performed using a search engine, which is a search engine site that provides search results for all information, and inputs a search term according to the desired information to receive web sites containing the search term as contents. . However, there is a problem in that the search results by the search engine are large and the quality of information is deteriorated, and reliability is not high.

As a means for users to obtain reliable information limited to a specific field, there is a method of obtaining information through a newsletter issued by a specialized institution or a club on the web formed by users with the same interests. However, newsletters tend to be used as one of the strategies for inducing visitors in the institution, and since they provide general information data, there are limitations in meeting each member's individual needs. In addition, clubs on the web are not easily accessible, and there is a limitation that the amount of information is limited even if the information is professional.

On the other hand, there are also services that the user uploads to the bulletin board on the web as a question to get the answers of other users. However, in the case of these services, even if the questioner gets an answer, there is a problem in that the reliability of the answer is low because the identity or professionalism of the answerer cannot be guaranteed. .

Even in the position of respondents, in order to provide high-quality answers, quantitative labor using the knowledge of the respondents and qualitative labor such as time, devotion, and effort required for the respondents to put in knowledge are required. And there is no compensation system corresponding to qualitative work. In addition, the conventional knowledge-answer service does not consider any copyright of the content generated through the knowledge of the respondents, and thus the motivation for sharing the knowledge of the users who need to be protected is inevitably reduced.

In one embodiment, the sidechain linker 36 stores information about the generated content in addition to the reward through the token in the sidechain for the blockchain network 6, thereby storing the content itself, not just the token, in the blockchain network (6 ).

On the other hand, if all content is stored in the sidechain, the processing performance of the transaction decreases, and the fee burden of the operator of the knowledge transaction platform providing system 30 increases, so in one embodiment, the sidechain linker 36 disperses the content itself. It may be stored in the storage 51, 52, but only the information about the storage location of the content (for example, a hash value of the storage location) may be included in the transaction to lighten the transaction.

In one embodiment, the content providing unit 37 serves to provide content generated through questions and answers of users so that other users can view the content. At this time, the content providing unit 37 may allow users who browse the content to pay a fee in tokens or real money to view a pair of question-answers or a portion thereof. In addition, the content provided by the content providing unit 37 is not limited to content generated by question-answer, and the content providing unit 37 uses audio-visual materials such as lectures and lectures created by experts, and chat services as content. In addition, advertisements may be provided when viewing these contents.

2 is a flowchart of a knowledge transaction service method according to an embodiment.

Referring to FIG. 2, first, the interrogator 1 may transmit question information to the knowledge transaction platform providing system 30 (S11). When the interrogator 1 uploads a question, the process of creating content through the knowledge transaction platform providing system 30 begins. More specifically, the content generation process consists of a content generation stage, a content curation stage, and a reward stage.

In the content creation step, the knowledge transaction platform providing system 30 provides the questioner's question information to the respondent 2 corresponding to the certified expert in the corresponding question field (S12), and answers corresponding to the question from the answerer 2 Information may be received (S13). However, in another embodiment, the responder 2 is not limited to an authenticated expert and may refer to any other user except the questioner 1. The content creation step is a step in which a set of questions and answers is created, and after this step is finished, no more answers can be registered.

In the drawing, the interrogator 1 and the interrogator 2 are expressed in the form of a subject interacting with the knowledge transaction platform providing system 30, but the actual transmission and reception of data is the user device 10 of the interrogator 1 (FIG. 1) It will be readily understood by those skilled in the art that it is performed using the user device 20 (FIG. 1) of the respondent 2 and the respondent 2. This also applies to the curator 4 described later. In addition, the question information and the answer information may be text data or the like used in a conventional bulletin board type service, but are not limited thereto, and the interrogator 1 transmits the question information in the form of a voice or video data file, or / It is also possible for the responder 2 to provide an answer to the question in the form of an audio or video data file, which is intended to be included in the scope of the embodiments of the present invention.

The questioner 1 may receive an answer from a plurality of answerers 2 for a predetermined time (eg, 24 hours) after registering the question. In addition, the respondents 2 can view and answer all questions that have not expired. In one embodiment, the interrogator 1 may review the answers registered from the respondents 2 for a predetermined time period, and then request an extension of time (eg, in 24-hour increments) for requesting additional answers, if additional answers are desired. However, the number of time extensions may be limited or unlimited. In addition, in the content generation step, the interrogator 1 may transmit evaluation information such as adoption or report on the answer of the responder 2 (S14).

The interrogator 1 ends the content creation step and adopts the content curation step by adopting the answer of the specific responder 2 when it is determined that a satisfactory answer has been registered even if the time allocated to the content creation step has not passed. Can be initiated. In addition, the questioner 1 can report immediately if it is determined that the registered answer to his question is content outside the correct knowledge ecosystem, such as advertisement, public relations, abusive language, obscenity, slander. Report of the interrogator 1 may be made for each answer when there are multiple answers.

The operator of the knowledge transaction platform providing system 30 can finally approve the report after confirming the report content and the response content if there is a reported answer, which is the knowledge transaction platform providing system 30 It means that the contents of the answers deleted or reported on the web are not exposed through the knowledge transaction platform providing system 30. This can be applied in the same way to the report made in the evaluation process by the curator 4 or another user, which will be described later.

If the answer to the question is registered, but the questioner (1) does not accept any answer during the time allotted to the content creation phase, or if the questioner (1) does not make an extension request for the time allotted to the content generation phase, The content creation phase ends automatically and the content curation phase proceeds. In this case, the questioner 1 is given an additional opportunity to adopt an answer and report an answer at the content curation stage.

The content curation step is a step in which curators 4 evaluate the registered questions and / or answers. In the content curation stage, the knowledge transaction platform providing system 30 curates the question information of the questioner 1 and the answer information of the answerer 2 for one or more other users than the questioner 1 or the answerer 2 (4) to provide (S15), and receive evaluation information such as likes, adoptions, or reports on answers from the curator (S16). In addition, the curator 4 can evaluate the question itself in addition to the answer of the respondent 2 as described above. This evaluation serves as a basis for compensation provided to the questioner 1, the responder 2, and the curator 4 in the compensation step described later.

On the other hand, for a fair evaluation, the responder 2 may not accept the answer of the user or evaluate the responses of other users registered for the question in which the user participated as the responder 2, such as adoption or report.

In one embodiment, the content curation step, like the content generation step, may last for a predetermined time (eg, 24 hours). During the content curation phase, the curator 4 may “like” the question when it is determined that it is a good question, and may also select one of the registered answers to adopt. At this time, the curator 4 may adopt only one of the answers and may make multiple adoption impossible.

In addition, the curator 4 may report an answer if it is determined that the registered answer is content outside the correct knowledge ecosystem, such as profanity, advertisement, obscenity, and slander. The report of the curator 4 may be made for each answer when there are multiple answers.

In one embodiment, when the interrogator 1 evaluates an answer, and when the curator 4 evaluates a question and / or answer, other users' ratings (e.g., 'like' number) are not exposed, purely The evaluation can be made with only the content of the question / answer. This is to prevent the synchronic effect of crowd sentiment, which many believe that the answers already selected are correct, and through this, more accurate curation is possible.

When the content curation step ends, the knowledge transaction platform providing system 30 determines an answer to be adopted for the question and generates content including at least the adopted answer among the questions and answers registered for the question. (S17). For example, the generated content may include a question taken by the questioner 1 and an answer adopted by the questioner 1 and / or the answers adopted by the curators 4 among the answers registered to the questioner 1, and adopted by the questioner 1 The answer and the answer adopted by the curators 4 may be the same or different from each other. In addition, the answers adopted by the curators 4 may be determined as the most adopted answer from the results of the adoption by the multiple curators 4.

In addition, the knowledge transaction platform providing system 30 may store the generated content in the storage 50 and provide it to users using the knowledge trading platform providing system 30 for viewing. The storage 50 may be part of the knowledge transaction platform providing system 30 or may be an external server. For example, the storage 50 may be the distributed data storage 51 and 52 described above with reference to FIG. 1. For example, the storage 50 may be a distributed file system (DFS), but is not limited thereto.

When the content curation step ends, the compensation step starts. In the reward step, the knowledge transaction platform providing system 30 calculates an activity score for each of the interrogator 1, the responder 2, and the curator 4 made in the content creation step and the content curation step (S19). , The token reward determined based on the calculated activity score is paid to the interrogator 1, the responder 2 and / or the curator 4. This can be achieved by uploading a token transaction corresponding to the determined reward to the knowledge transaction platform providing system 30 to a data block on the blockchain network 6 (S20), and the detailed process will be described later in detail.

On the other hand, after the content curation stage is over, other users except the questioner 1 and the answerer 2 can individually evaluate and answer questions and answers in the completed content through 'like'.

The operation by the knowledge transaction service method according to the above-described embodiments may be at least partially implemented as a computer program and recorded in a computer-readable recording medium. A program for implementing an operation by the knowledge transaction service method according to embodiments is recorded and a computer-readable recording medium includes all types of recording devices in which data that can be read by a computer are stored. Examples of computer-readable recording media include ROM, RAM, CD-ROM, magnetic tape, floppy disks, and optical data storage devices. The computer-readable recording medium can also be distributed over network coupled computer systems so that the computer readable code is stored and executed in a distributed fashion. In addition, functional programs, codes, and code segments for implementing the present embodiment will be readily understood by those skilled in the art to which this embodiment belongs.

Referring to FIG. 3, users such as the questioner 1 and the responder 2 communicate with the application layer of the knowledge trading platform providing system 30 to perform activities such as questions and answers, and provide a knowledge trading platform according to the contribution degree The activity score is given by the system 30. In addition, in one embodiment, activity scores may be subdivided into participation scores and reputation scores, and detailed score calculation will be described later.

The reward management unit 34 distributes tokens based on a blockchain network capable of transmitting and receiving between users on the blockchain network, and provides tokens as rewards to users in proportion to the activity scores of users. That is, the tokens are paid to each user's electronic wallet through the token contract on the blockchain in proportion to the user's activity score. For example, in one embodiment, the token may be an Ethereum ERC20 standard compatible token, but is not limited thereto.

In one embodiment, the reward management unit 34 manages the token transaction via a third-party electronic wallet service without uploading the transaction that transmits the token contract directly onto the blockchain network. That is, the reward management unit 34 transmits a request to pay the reward to each user to the electronic wallet service side, and transmits the token from the account of the knowledge transaction platform providing system 30 to the electronic wallet account of each user through the electronic wallet service. Transmission is made.

The e-wallet service manages token transactions based on the user account of the e-wallet service, and it can be synchronized with the blockchain network periodically (for example, once a day). As such, instead of using the transaction of the mainnet of the blockchain network, through the separate e-wallet service, the transmission speed is fast, and there is no need to pay the transaction fee of the mainnet every token contract, and the user does not need to pay the mainnet. There is an advantage in that the service can be easily performed even for users who are not familiar with the blockchain network because there is no burden of creating an account address and storing a private key.

However, this is an example, and in another embodiment, the reward management unit 34 may upload a transaction corresponding to the token contract directly to the mainnet of the blockchain network without going through a separate electronic wallet service.

In addition, the content management unit 33 may store content generated from questions and answers in the storage 50 and read content from the storage 50 when providing the content for viewing by users. The storage 50 may be a centralized server or distributed data storage inside or outside the knowledge transaction platform providing system 30.

On the other hand, since the contents are directly provided by users, it is preferable to record them in a data block on a blockchain network and disclose them for anyone to read, rather than being attributed to a single subject or device. In addition, by recording data on the blockchain, there is an advantage that it becomes easy to prove copyright in case of problems such as unauthorized copying or premise of data. Accordingly, in one embodiment, the content management unit 33 may upload the content generated from the users' questions and answers in the form of a transaction to the data block on the blockchain network, similar to the token contract described above.

However, writing data to the blockchain means that it generates transactions, which creates a burden in terms of transaction speed and fees. In order to solve this problem, in one embodiment, the sidechain linker 36 of the knowledge transaction platform providing system 30 uses information corresponding to the content on the sidechain through the sidechain service rather than the mainnet of the blockchain network. You can upload to a data block.

When the content information is uploaded to the sidechain by the sidechain interworking unit 36, the transaction processing speed can be greatly increased by introducing a sidechain using a consensus algorithm such as Proof of Authority (POA), This has the advantage of lowering the burden of fees. In addition, there are advantages such as allowing the service provider of the sidechain service to pay the transaction fee, and can use the signature function of a third-party e-wallet application with high ease of use to easily sign the transaction.

However, when all the information of the content is recorded on the sidechain, the processing performance of the transaction may be deteriorated, and the fee burden of the service provider providing the sidechain service may increase. In order to solve this problem, in one embodiment, the content itself is stored in the distributed data storage 50 by the content management unit 33, and the sidechain linkage unit 36 is a storage location of the content on the distributed data storage 50 Transactions can be made lighter by uploading only information to the sidechain. For example, the sidechain linker 36 may upload a hash value corresponding to the storage location of the content to the sidechain in response to the transaction.

In the knowledge transaction platform providing system 30 described above, by establishing a systematic standard for users who have contributed to the activation of knowledge transactions and network expansion, token rewards are provided to induce more participation of users. Specifically, the reward management unit 34 of the knowledge transaction platform providing system 30 assigns activity scores to user activities performed on the platform provided by the knowledge transaction platform providing system 30 in connection with content, and a certain time The amount of compensation paid to each user may be determined based on the ratio of the activity score of each user (ie, questioner, answerer, and curator) in the sum of activity scores given during the period.

Specifically, the reward management unit 34, regardless of the role of each user (that is, the role of the questioner, the responder, and the curator), each user commonly accesses the knowledge transaction platform providing system 30 (ie, service visit) or , Activity scores may be assigned to the content provided by the knowledge transaction platform providing system 30 for sharing or evaluating (eg, displaying or reporting likes).

For example, in one embodiment, activity scores that are commonly assigned regardless of user roles may be defined as in Table 1 below.

division Participating activities Activity score Explanation common Service visit 5 Once per account per account /
Operating attendance compensation system (first 60 times after the first login) Content sharing Sharer 4

Upon final approval of report content,
Only the first 10 people who participated in the report are compensated
Limited to 12 times per day for reporting function participation Content likes - No activity compensation, only used for content sympathy

In addition, the reward management unit 34, for the user corresponding to the questioner, the generation of the question information, the adoption of the answer corresponding to the question, the evaluation of the curator to the question (eg, like the mark, etc.), and / or the adopted answer Activity scores can be assigned based on the evaluation of curators.

For example, in one embodiment, an activity score assigned to an interrogator may be defined as Table 2 below.

division Participating activities Activity score Explanation questioner Write a question - No activity compensation for question writing itself Answer adoption 12 Adoption of an answer registered to your question,
In response to the adoption of the answer, the number of likes received by the question is proportional to
Payment of compensation Like reception
(Questions) 4 Register answers to questions + Adopt answers = Reward only when two conditions are met Rewards 4 points per number of likes received when payment is satisfied Like reception
(answer) 4 After the curating stage, rewards are also given to the questioner, 4 points per answer received.

In addition, the reward management unit 34, for the user corresponding to the respondent, the generation of the answer information, the adoption of the interrogator for the answer, the adoption of the curator for the answer, and / or the evaluation of the curator for the answer (for example, like indication) Activity scores may be assigned based on the like.

For example, in one embodiment, an activity score assigned to an answerer may be defined as in Table 3 below.

division Participating activities Activity score Explanation Respondent Write an answer 80 No compensation if report of response is approved
However, if a question is deleted through a report and the answer is also deleted, the respondent has no reason for retribution, so compensation for writing the answer is paid. Answer adoption

(Per answer)
No compensation if report of response is approved Answer adoption
(by curator) 200 If the respondent's answer has been adopted by curators,
Distribution in proportion to the number of adoptions received in the overall score of 200 points.
No compensation if report of response is approved Like reception
(answer) 2 Rewards 2 points for each likes received after the curating phase

In addition, the reward management unit 34 may assign an activity score to a user corresponding to the curator based on the answer adopted by the curator by the questioner or other curator.

For example, in one embodiment, an activity score assigned to a curator may be defined as in Table 4 below.

division Participating activities Activity score Explanation Curator Answer adoption 4 Adoption of responses up to 15 times a day No action compensation for the adoption itself
However, if the answer adopted by the curator is (1) the questioner is also adopted, or (2) the other curator is also adopted, compensation is paid ((1), (2) can be duplicated)

On the other hand, in one embodiment, the respondents correspond to the general domain, and the attorneys, lawyers, patent attorneys, lawyers, administrators, labor consultants, tax accountants, accountants, doctors, oriental doctors, pharmacists, etc. It can be classified as a respondent in a professional area corresponding to a national professional. In this case, for the respondents in the professional area, the expertise can be recognized and the activity score can be assigned based on different criteria from the respondents in the general area.

For example, in one embodiment, activity scores assigned to respondents in a professional area may be defined as in Table 5 below.

division Participating activities Activity score Explanation Respondent Write an answer 150 No compensation if report of response is approved
However, if a question is deleted through a report and the answer is also deleted, the respondent has no reason for retribution, so compensation for writing the answer is paid. Answer adoption
(by questioner) 400 No compensation if report of response is approved Answer adoption
(by curator) 360 If the respondent's answer has been adopted by curators,
Distribution in proportion to the number of adoptions received in 360 overall scores.
No compensation if report of response is approved Like reception
(answer) 8 Rewards 8 points for each likes received after the curating phase

However, the definition of each activity described in Tables 1 to 5 above and the numerical value of the activity score corresponding to each activity are exemplary, which may be set in various ways by an operator of the knowledge transaction platform providing system 30. , Not limited to those described herein.

The reward management unit 34 calculates the sum of activity scores of users participating in the platform provided by the knowledge transaction platform providing system 30 at regular intervals (eg, daily), and calculates the sum as the activity score of each user. Token rewards can be provided in proportion to the divided value.

For example, the total amount of tokens to be paid as daily rewards from the tokens managed by the knowledge transaction platform providing system 30 is called a token _{daily supply} , and the score for each activity according to the participation activity is P and the activity of user X When the score is P _X , Daily Token Reward _{User X, which} is a token reward paid to _{User X} , may be defined as Equation 1 below.

In addition, in one embodiment, the compensation management unit 34 may further provide a reputation-based compensation in addition to the compensation provided by the above activity scores. Reputation rewards are rewards that are paid at a relatively longer period (e.g., once a month) compared to the payment period (e.g., once a day) of rewards based on activity scores. It can be paid in proportion. In addition, in one embodiment, the knowledge transaction platform providing system 30 provides a follow function to subscribe content of other users between users, and reflects the number of followers who subscribe to the content of each user. You can also decide your reputation.

For example, a user's reputation may be determined based on a value calculated by the formula of [(A) number of followers value + (B) value of sympathy (eg, like sign) + (C) value of answer adoption-(D) report value] have. In addition, in one embodiment, the user's reputation may be determined by grade as shown in Table 6 below.

reputation Rating 0 ~ 99 Grade 11 100 ~ 199 Grade 10 200 ~ 299 Grade 9 300 ~ 399 Grade 8 400 ~ 499 Grade 7 500 ~ 599 Grade 6 600 ~ 699 Grade 5 700 ~ 799 Level 4 800 ~ 899 Level 3 900 ~ 960 Level 2 961 ~ Level 1

In addition, since the number of followers of a specific user means that the user has a lot of influence on other users based on their expertise, the weight proportional to the number of followers of the user in determining reputation is defined as shown in Table 7 below. You can.

reputation weight 0 ~ 99 One 100 ~ 199 1.1 200 ~ 299 1.2 300 ~ 399 1.3 400 ~ 499 1.4 500 ~ 1.5

At this time, the reward determining unit 34 accumulates the reputation scores converted for each fixed period (eg, daily), and calculates the final value based on a predetermined perfect score (eg, 100 points) for each long period (eg, monthly). can do.

For example, if the daily reputation score is RP _daily , the number of likes per day is P _{daily like} , the number of responses adopted per day is P _{daily selected} , the number of reports per day is P _{daily report} , and the weight according to the number of followers is W, one day in one embodiment The formula for calculating the reputation score is as shown in Equation 2 below.

In addition, at this time, the cumulative reputation score RP _user of the corresponding _user is as shown in Equation 3 below, and the final reputation score R _user for the _user is calculated as shown in Equation 4 below with a perfect score of 1000 points.

However, the above equations 2 to 4 are exemplary, and the method of numerically evaluating the reputation accumulated by the user through the knowledge transaction platform providing system 30 is not limited to the above.

4 is a conceptual diagram showing information recorded in a data block on a blockchain network in a knowledge transaction service method according to an embodiment.

4 exemplarily shows information recorded in each data block in a blockchain composed of data blocks connected to each other on a blockchain network. As shown, information about the movement of the token between the user's activity history and the account corresponding to the activity history is stored in each data block in the form of a transaction. The blockchain shown in FIG. 4 may correspond to the mainnet of the blockchain network, but the blockchain as illustrated may be implemented on the sidechain to reduce transaction fees.

5 is a conceptual diagram illustrating a connection between information recorded in a data block on a blockchain network and content stored in a distributed data storage in a knowledge transaction service method according to an embodiment.

Referring to FIG. 5, in the present embodiment, the question information stored in the distributed data storage includes metadata (eg, an account of the questioner, a timestamp corresponding to the time of the question) as well as question information that is the actual content of the question. In addition, the answer data stored in the distributed data storage includes a question hash indicating the storage location of the question information, which is the target of the answer, along with the answer information that is the actual content of the answer. Time stamp, etc.).

At this time, the transaction recorded in the data block on the blockchain network does not completely contain the content or the content metadata itself, but includes the storage location information on the distributed data storage of questions and / or answers in the form of a hash. That is, the question transaction includes a question hash indicating the storage location of the question information, and the answer transaction includes the question hash and the answer hash indicating the storage location of the answer information. In addition, in the case of a curation transaction, an answer hash indicating a storage location of answer information evaluated by the curator is included.

Through the above storage method, the contents and transactions shared through the knowledge transaction platform providing system according to the embodiments are all stored in the blockchain and distributed data storage, but the contents of the blockchain itself are not stored in the blockchain network, The capacity can be prevented from being enlarged. Meanwhile, in another embodiment, the distributed data storage may be replaced by a centralized server for smooth traffic expansion.

6 is a conceptual diagram illustrating an encryption process for protecting a user's personal information in a knowledge transaction service method according to an embodiment.

Referring to FIG. 6, content stored in the distributed data storage 51 in the knowledge transaction platform providing system according to the embodiments may be divided into actual content of content and content metadata (eg, producer, production date, etc.). . At this time, the metadata may include sensitive information such as a real name, email, and phone number that can identify a user, so it is necessary to safely protect such information from external exposure. In addition, in order to facilitate the proof of copyright, it may be necessary to encrypt the content metadata to prevent arbitrary third parties from accessing it freely.

Therefore, in this embodiment, content and content metadata are signed with the user's private key and stored in the distributed data storage 51, so that the content can be viewed only when decrypted with the user's public key. In addition, the user's key is stored in a separate key management server 70, which is separated from the distributed data storage 51, wherein the key management server 70 is only through a private application programming interface (API) of the knowledge transaction platform providing system. It can be protected from being called.

In FIG. 6, dashed arrows indicate a process of encrypting data and storing it in the distributed data storage 51, and solid arrows indicate a process of loading encrypted data stored in the distributed data storage 51.

Looking at the storage process, the user's storage request through the application layer is transmitted to the core layer, and the core layer transmits metadata associated with the user to the key management server 70. At this time, metadata associated with the transmitted user is first encrypted and transmitted with the user's public key. The encrypted content data transmitted in this way can be encrypted once again with the key of the key management server 70 and stored in the distributed data storage 51.

Next, looking at the load process of loading the stored data, if there is a user request through the application layer, the application layer receives a request after a separate 2 factor authentication to the user. Thereafter, in the core layer, encrypted content metadata can be retrieved from the distributed data storage 51. Next, the core layer requests the encrypted content metadata to the key management server 70, decrypts it, and delivers it to the user. At this time, the data delivered to the user cannot be decrypted without the user's own private key.
