Abstract: A node device according to various embodiments of the present disclosure may determine whether a code displayed on a terminal of a user and recognized by a reader provided at an event venue of an event is valid by executing a smart contract related to the event. The smart contract may include instructions to determine whether the code is valid, based on first ticket information including information corresponding to each of one or more first non-fungible tokens (NFTs) minted in association with the event and encrypted information, upon obtaining the encrypted information corresponding to the code from the reader that recognizes the code.

Abstract: The present disclosure relates to a method, an apparatus, and a recording medium for providing a platform including a trade service of an NFT representing a ticket. The method according to an embodiment of the present disclosure may be performed by at least one processor and include operations of: acquiring a request for generating a first account for an NFT-related service from a terminal of a user, the request for generating the first account indicating another service distinguished from the NFT-related service; acquiring information about a second account corresponding to an account of the user in the another service; generating the first account of the user for the NFT-related service based on the information about the second account; and generating a first digital asset wallet of the user and associating information about the first digital asset wallet with the first account of the user.

Abstract: Provided is a hybrid super capacitor using a composite electrode that may enhance equivalent series resistance (ESR) using a carbon nanotube chain. The hybrid super capacitor includes: an anode 11 including an anode oxide layer 11a and an activated carbon layer applied 11b on the anode oxide layer 11a; and a cathode 21 being disposed to face the anode 11. The cathode 21 may include a silicon oxide layer 21a, a lithium titanium oxide layer 21b disposed on the silicon oxide layer 21a, and a carbon nanotube chain CT formed to pass through the silicon oxide layer 21a and the lithium titanium oxide layer 21b to thereby be electrically connected to each other, thereby enhancing ESR and expanding an output density and a lifespan of the hybrid super capacitor.
