1. A method in an electronic device of managing non-fungible token (NFT) transactions in absence of a blockchain, the method comprising:
generating, via at least one processor, an NFT for target content in response to receiving a request to register the target content from a first external electronic device;
generating, for addition to the NFT, a certification authority (CA) signature indicating that the NFT is generated by the electronic device;
transmitting, via a communication circuitry, the NFT to the first external electronic device, wherein an ownership signature is added to the NFT, together with the CA signature, the ownership signature based on a private key of a user to which ownership of the NFT is assigned; and
in response to receiving, from a second external electronic device from among a plurality of NFT-related external electronic devices, a request to purchase the NFT, processing, via the at least one processor and the second external electronic device, a transfer of the NFT from a preceding owner to a new owner, in absence of communicative transmissions related to the transfer with a remainder of the plurality of NFT-related external electronic devices.
