In this case, the attendance performance information may include a photo or video containing a task or one's own exercise scene in response to the online lecture. The value of the above course performance information must belong to the producer, and other third parties must not use it without permission, so this is also for NFT.

In addition, the NFT-based freelance history information management platform service providing method according to an embodiment may record the attendance information in a third token, and attribute the third token to the second ID.

In addition, the method of providing an NFT-based freelance history information management platform service according to an embodiment allocates a reward corresponding to the course performance information to the second ID of the online student who has taken the online lecture, and gives the second token Information about the reward may be recorded.

This is to induce the online students taking the online lecture to actively participate in the task or follow (photo or video) of the corresponding lecture. Through this, online students can apply for online lectures in the future based on the rewards.

In this case, the reward may be a blockchain-based coin or token.

In addition, the method of providing an NFT-based freelance history information management platform service according to an embodiment may store the second token and the third token in the blockchain network to NFT.

As described above, the personal history information is inevitably input by the freelance user himself/herself. However, for this reason, it is necessary to determine the reliability information of the corresponding information.

To this end, the NFT-based freelance history information management platform service providing method according to an embodiment performs verification of the personal history information from other freelance users who have the same history as at least one of the lecture history information and the attendance history information. to generate the reliability information.

In this case, the generating of the reliability information may include extracting history place information and history time point information from at least one of the lecture history information and the attendance history information of the first freelance user. This is to find another freelance user who conducted the same lecture at the same place and time by extracting the place and time of the lecture conducted or taken by the first freelance user.

In general, in the case of freelancers, since it is common to be limited to a specific industry, lectures that must be taken or places where lectures are performed may overlap. Through this, it is possible to verify the history of the first freelance user by extracting other freelance users with overlapping places and viewpoints.

To this end, the generating of the reliability information may include extracting a plurality of second freelance users in which the history place information and the history time point information are matched.

In addition, the step of generating the reliability information includes the verification request information of the lecture history information or the attendance history information of the first freelance user to the second freelance user terminal 200 used by the plurality of second freelance users. can send

In this case, the verification request information may be initiated so that the first freelance user requests objective verification information or subjective verification information for the lecture history information or the attendance history information.

In this case, the objective verification information may mean objective information that the lecture history information or the attendance history information of the first freelance user is genuine, that is, a photograph or documented evidence, and the subjective verification information is the second freelance user has witnessed the first freelance user or is personally acquainted with the first freelance user, and thus may mean evidence to testify that the lecture history information or the attendance history information is the truth.

In addition, the generating of the reliability information may include receiving first verification feedback information corresponding to the verification request information from the second freelance user terminal 200 . In this case, the first verification feedback information may be at least one of the above-described objective verification information and subjective verification information. In this case, when the first verification feedback information is objective verification information, it may include quantity information on evidence, and in the case of the subjective verification information, it may include the number of positive feedbacks and the number of negative feedbacks.

In addition, the generating of the reliability information may include receiving second verification feedback information corresponding to the evaluation of the online lecture to the online student terminal 300 . This is to determine from the student's point of view whether the lecture history information or the lecture history information of the first freelance user is an appropriate lecture level. In this case, the second verification feedback information may be a score selected by the online student according to a preset evaluation score level. For example, it may be a score (1 point, 2 points, etc.) selected by the online student in the evaluation score level set as out of 10 points.

In addition, the generating of the reliability information comprises calculating the average number of online students based on the entire lecture history information stored in the blockchain network, and based on the average number of online students and the number of online students included in the lecture history information. Third verification feedback information may be generated.

If the number of online students is more than a certain number, this is a rebuttal to the fact that their ability has been objectively recognized.

In addition, the generating of the reliability information may include generating the reliability information based on the first verification feedback information, the second verification feedback information, and the third verification feedback information.

In this case, the reliability information may be included in the personal history information and recorded in the first token.

In addition, as a method for evaluating the lecture ability of freelance users, it may be evaluated based on the conversation contents conducted during the online lecture.

To this end, in the method for providing an NFT-based freelance history information management platform service according to an embodiment, when the online lecture being performed by the freelance user ends, the freelance user and the plurality of online lectures input into a chat window while taking the online lecture It is possible to obtain the conversation information of the students. To this end, a chat window may be provided so that freelance users and online students can exchange opinions while the online lecture is being performed.

In addition, the NFT-based freelance history information management platform service providing method according to an embodiment may extract the conversation information of the freelance user input by the freelance user from the conversation information.
