9 . A method for operating an electronic device, the method comprising: obtaining first identification information associated with an external electronic device and second identification information of a non-fungible token (NFT) associated with the external electronic device; and based on obtaining the first identification information and the second identification information, transmitting, to a server, a first blockchain address of a first wallet application stored in the electronic device, first account information of a user of the electronic device, the first identification information, and the second identification information, the transmission comprising a request to change an ownership of the NFT created in a blockchain network, wherein based on the first blockchain address and the first account information being comprised in the NFT in the blockchain network, the ownership of the NFT is changed to the first blockchain address.
10 . The method of claim 9 , further comprising: subsequent to changing the ownership of the NFT to the first blockchain address, based on a transfer of the ownership of the NFT to another blockchain address being requested, transmitting, to the server, at least one of a second blockchain address of a second wallet application stored in a second electronic device or second account information registered in the server, wherein based on the second blockchain address and the second account information being comprised in the NFT in the blockchain network, the ownership of the NFT is changed to the second blockchain address.
11 . The method of claim 10 , wherein the transmitting the at least one of the second blockchain address or the second account information to the server comprises: based on the second blockchain address and the second account information being linked in the blockchain network, transmitting, to the server, one of the second blockchain address or the second account information, the transmission of the second blockchain address or the second account information comprising the request transfer of the ownership of the NFT.
12 . The method of claim 10 , further comprising: receiving an input of at least one of the second blockchain address or the second account information via the first wallet application to request the server to transfer the ownership of the NFT.
13 . The method of claim 9 , wherein initial ownership of the NFT is designated to a blockchain address associated with a manufacturer of the external electronic device, and based on the first blockchain address and the first account information being transmitted to the blockchain network by the server, the ownership of the NFT is changed from the blockchain address associated with the manufacturer to the first blockchain address.
14 . The method of claim 9 , wherein the obtaining the first identification information and the second identification information comprises: capturing, through a camera, a QR code associated with the external electronic device; and obtaining the first identification information and the second identification information based on the QR code.

Description

CROSS-REFERENCES TO RELATED APPLICATIONS This application claims priority to International Application No. PCT/KR2024/008881, filed on Jun. 26, 2024, which is based on and claims priority to Korean Patent Application No. 10-2023-0086184, filed on Jul. 4, 2023, and Korean Patent Application No. 10-2023-0173792, filed on Dec. 4, 2023, in the Korean Intellectual Property Office, the disclosures of which are incorporated by reference herein in their entireties. BACKGROUND 1. Field The disclosure relates to an electronic device requesting change of ownership of a non-fungible token (NFT), a method of operating the same, and a server. 2. Related Art Since blockchain-based bitcoin became public, blockchain has applications in various sectors, such as smart contract-based platform services or non-fungible token (NFT), cloud storage services, blockchain computing services, as well as electronic currency (cryptocurrency or virtual currency) systems, e.g., bitcoin. A blockchain platform allows system participants (nodes) to distribute and store data in their respective blocks, thus substantially free from data forgery and falsification (reliability) and allowing the participants to own their distributed information (transparency), with no need for a separate central server manager. An NFT may refer to a virtual token that proves ownership of digital assets using blockchain technology. For example, an NFT may be used to indicate unique originality and ownership by including an address pointing to digital files such as images and videos within the token. An NFT may be guaranteed its uniqueness by permanently recording transaction history on the blockchain. SUMMARY According to an aspect of the disclosure, an electronic device may include a camera; a communication circuit; a processor; and memory configured to store instructions, where the instructions, when executed by the processor individually or collectively, cause the electronic device to obtain first identification information associated with an external electronic device and second identification information of a non-fungible token (NFT) associated with the external electronic device; and based on obtaining the first identification information and the second identification information, transmit, to a server through the communication circuit, a first blockchain address of a first wallet application stored in the memory, first account information of a user of the electronic device, the first identification information, and the second identification information, the transmission comprising a request to change an ownership of the NFT created in a blockchain network, where when the first blockchain address and the first account information are comprised in the NFT in the blockchain network, the ownership of the NFT is changed to the first blockchain address. According to an aspect of the disclosure, a method of operating a first electronic device may include obtaining first identification information associated with an external electronic device and second identification information of a non-fungible token (NFT) associated with the external electronic device; and based on obtaining the first identification information and the second identification information, transmitting, to a server, a first blockchain address of a first wallet application stored in the electronic device, first account information of a user of the electronic device, the first identification information, and the second identification information, the transmission including a request to change an ownership of the NFT created in a blockchain network, wherein based on the first blockchain address and the first account information being included in the NFT in the blockchain network, the ownership of the NFT is changed to the first blockchain address. According to an aspect of the disclosure, a server may include a database storing user information including account information and blockchain addresses of users, a communication unit, and a controller. According to an embodiment, the controller may be configured to request the blockchain network to change ownership of an NFT for the external electronic device to the first blockchain address through the communication unit, based on receiving first identification information of an external electronic device, second identification information of an NFT for the external electronic device, a first blockchain address of the electronic device, and first account information of a user of the electronic device from an electronic device. According to an embodiment, the controller may be configured to monitor changes in ownership of a non-fungible token (NFT) for an external electronic device 207 through a blockchain network. According to an embodiment, the controller may be configured to transmit information about ownership of the NFT to the external electronic device if a change in ownership of the NFT is identified.
