A method, performed by a server, of managing a non-fungible token (NFT) for content, is provided. The method includes, in response to receiving a request to issue an NFT for target content from a first electronic device of a first user who has generated the target content, generating basic metadata on the target content, uploading the generated basic metadata to a target folder generated in an interplanetary file system (IPFS), generating first ownership metadata including a content identifier (CID) of the uploaded basic metadata, obtaining a first CID of the target folder with the first ownership metadata uploaded to the target folder, and linking the obtained first CID of the target folder to an NFT uniform resource identifier (URI) of the target content.

Apparatus and method of issuing centralized non-fungible token by using interplanetary file system

The disclosure relates to an electronic device for generating a mnemonic phrase of a private key and an operation method in the electronic device. The electronic device may comprise a memory, a display module, and at least one processor electrically connected with the memory and the display module. The at least one processor may be configured to generate a private key and a public key, generate a first mnemonic phrase including a designated first number of words based on a structure of the private key, identify a user phrase input by a user, generate a second mnemonic phrase including a second number of words identified based on a security level obtained by analyzing the user phrase, and control the display module to display the generated second mnemonic phrase. Other embodiments are possible.

Electronic device for generating mnemonic phrase of private key and operation method in the electronic device

A method and device for non-fungible token (NFT)-based software is disclosed. A method of running the NFT-based software performed on the device includes: running the NFT-based software in response to an execution request for executing the NFT-based software; loading NFT metadata including identification information indicating the NFT-based software, identification information indicating an owner of the NFT-based software, and specified engraving data, in response to the execution request; and outputting the engraving data included in the NFT metadata based on an event occurring as the NFT-based software runs.

Method and device for NFT-based software

An electronic device and method are disclosed for managing a non-fungible token (NFT). The electronic device includes: a memory configured to store computer-executable instructions, and a processor. The processor implements the method, including: generating, a NFT for target content in response to receiving a request to register the target content from a first external electronic device, generating, for the NFT, a certification authority (CA) signature indicating that the NFT is generated by the server, and 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.

Method and apparatus for managing non-fungible token for digital content

A lift apparatus for moving an object up and down in a substrate processing apparatus, the lift apparatus including a body configured to support the object while a lift hole, included in the body, is overlapped by the object in a vertical direction; a lift pin configured to move the object up and down by moving up and down in the lift hole; a bellows including an upper flange, a lower flange, and a flexible pipe; a connector combined with a lower portion of the lift pin in the flexible pipe and configured to interfere with downward movement of the lift pin and to allow at least one from among rotation, sliding, and tilting of the lift pin; a load sensor configured to measure vertical load generated in accordance with movement of the lift pin; and an actuator configured to move the lift pin up and down.

Lift apparatus and substrate processing apparatus including the same

An electrostatic chuck includes a chuck plate configured to mount a substrate, an insulation pillar provided outside the chuck plate, the insulation pillar having a pin hole formed therein, a first movable ring provided on the insulation pillar, surrounding a side of the chuck plate, a second movable ring configured to cover at least a part of an upper portion of the first movable ring, and a driving pin configured to move in the pin hole of the insulation pillar in a vertical direction, the driving pin overlapped by at least a part of the first movable ring and at least a part of the second movable ring in the vertical direction. The driving pin is configured to drive the first movable ring and the second movable ring in the vertical direction or to drive the second movable ring in the vertical direction.

Electrostatic chuck and substrate processing apparatus including the same

Disclosed are a digital device and method of processing data therein. The present invention includes a first receiving unit for receiving application data, a second receiving unit for receiving a signal including a request for a search service and search word data for the search service, a memory storing search history data, a controller configured to perform a first operation based on the search word data in response to the received search service request, control to display a first search result data on a screen, if the displayed first search result data is not valid, add the received search word data to the search history data, and control to display a second search result data on the screen by performing a second search based on the search word data included in the search history data after the search service, and a display unit displaying the application data, the first search result data and the second search result data.
