Description

Electronic device and method for performing non-fungible token-based service including download ranking information of digital content

Various embodiments disclosed in this document relate to an electronic device that performs a service of issuing and transacting a non-fungible token including a download order of digital content, and an operating method of the electronic device. Specifically, the present invention relates to an electronic device that provides a service of issuing non-fungible tokens according to download ranks for digital content and trading the tokens according to ranks in an auction or sale method.

Assets that can be traded at the same value as Bitcoin are all types of fungible tokens. Fungible cryptocurrencies can be exchanged 1:1 with other cryptocurrencies.

On the other hand, NFT stands for non-fungible token, and refers to a specific cryptographic digital asset in which one token cannot be replaced with another. NFTs are rare because each token represents a unique asset with different values. In other words, non-fungible tokens are non-tradable cryptocurrencies, and 1:1 transactions cannot be established.

Therefore, each non-fungible token has scarcity and can prove irreversible transactions. Non-fungible tokens are already being used for transactions in games, music, art, and virtual space through the advantage of being able to tokenize almost anything. For example, recently, the market for issuing and trading NFTs for specific items and characters in online and mobile games, real estate and digital artworks in virtual spaces or communities within games is expanding.

Various embodiments disclosed in this document may issue non-fungible tokens for digital content and provide services for trading the issued tokens.

Specifically, the electronic device according to various embodiments disclosed in this document may receive a request for issuance of a non-fungible token for digital content from a copyright holder and issue tokens of first to nth ranks according to download ranks. In addition, the electronic device of various embodiments disclosed in this document may conduct a transaction with users for the generated non-fungible token.

For example, the copyright owner may request the electronic device disclosed in this document to issue and auction NFTs from the 1st to the 10th download ranks for the sound source A. The electronic device may issue 10 NFTs from the first rank to the tenth rank for sound source A, and may proceed with an auction for each NFT. For example, users may input a purchase price for an NFT of a specific rank of a sound source they want to purchase in an auction held on an electronic device, and the electronic device may win the bid for the first user who offered the highest price. . The electronic device may determine the successful first user as the owner of the NFT and propagate a block in which the first user is recorded as the owner in the NFT to the node.

In addition, the first user who owns the NFT after winning the bid may request a re-transaction of the NFT to the electronic device. For example, a first user may request the sale of a first-ranked NFT of A sound source at X price, and a second user may purchase it. In response to the completion of the transaction between the first user and the second user, the electronic device may propagate to the node a block in which the second user is recorded as the owner of the first-rank NFT of the sound source A.

The technical problem to be achieved in this document is not limited to the technical problem mentioned above, and other technical problems not mentioned can be clearly understood by those skilled in the art from the description below. There will be.

An electronic device providing a service based on a non-fungible token (NFT) according to various embodiments disclosed in this document includes a communication unit, a storage unit, and a control unit operatively connected to the communication unit and the storage unit; Including, wherein the control unit receives a request to create an NFT corresponding to specific digital content from an external electronic device through the communication unit, and in response to the NFT creation request, using block chain technology to generate the specific digital content.
