Abstract: Disclosed is a method for use in a virtual asset transmission from a sender having a sending account at a sending virtual asset service provider (sending VASP) to a recipient having a receiving account at a receiving virtual asset service provider (receiving VASP).

Abstract: The present disclosure provides a method of providing a reward to a token owner. The method may include executing a smart contract for providing a reward to an owner of a token corresponding to a share of real property, and the smart contract may include: an instruction to transmit a first subtoken and a second subtoken corresponding to the token to a first account; an instruction to provide a first reward for the second subtoken to the first account; an instruction to transmit the second subtoken to a second account in response to receiving rental data for the token between the first account and the second account; and an instruction to provide the first reward to the second account when the second subtoken has been transmitted to the second account.

Abstract: Provided is an electronic device including a communication interface, one or more memories, and one or more processors configured to receive, from a user terminal of a user, a rental request for a digital asset corresponding to a first token, and to perform a procedure of generating a second token based on the rental request. The first token is generated based on a first smart contract configured to prove ownership of the digital asset, and first metadata of the first token indicates an owner having the ownership of the digital asset. The second token is generated based on a second smart contract configured to prove a right of use of the digital asset, and second metadata of the second token indicates a person having the right of use of the digital asset. Generation information of the second token indicating a rental history of the digital asset is recorded in the first metadata of the first token.

Abstract: A method includes obtaining, from a terminal operated by a user, by a processor connected with a computer network including a blockchain service, an access request to request access to an area of a virtual space including multiple areas; based on the access request, obtaining, by the processor, first information including non-fungible token information, the first information configured to be used to determine whether the user is authorized to access the area of the virtual space; verifying, by the processor, based on the first information, an access right of whether the area of the virtual space is accessible to the user by determining whether a non-fungible token is owned by the user and by determining whether the non-fungible token satisfies the non-fungible token information of the first information; and based on a result of the verifying, transmitting to the terminal, by the processor, a response to the access request.

Abstract: The present disclosure provides methods for generating and processing a token of a user by an electronic device. In some embodiments, the method includes receiving, from a user terminal, a message requesting to register the token. The token has been generated based on payment information of the user and a smart contract that uses the payment information. The method further includes registering the token, based on obtaining, from a blockchain network, a successful verification of the token. The method further includes updating a registration status of the registered token, based on the payment information. The method further includes determining whether to provide the user a reward for the registered token.

Abstract: An electronic apparatus includes a communication interface configured to communicate with one or more nodes of a blockchain network and an external device; one or more memories configured to store one or more instructions; and one or more processors configured to execute the one or more instructions to: receive a registration request for a token for a date from the external device; register the token to correspond to the date based on the registration request; and transmit posting information associated with the date to the external device, wherein the posting information includes a display attribute of an entry corresponding to the token, wherein the registration request includes date indication information indicating the date, and token identification information identifying the token.

Abstract: Provided is an electronic apparatus including a communication interface configured to communicate with one or more nodes of a blockchain network and a first external device, one or more memories configured to store instructions, and one or more processors configured to execute the one or more instructions to generate display information for a contents display area based on token information of tokens registered to respectively correspond to a plurality of unit areas included in the contents display area, and transmit, via the communication interface, the display information to the first external device. The display information indicates at least one image to be displayed in the contents display area displayed on the first external device. The transmitting of the display information causes the first external device to display the display information in the contents display area on the first external device.

Abstract: A system for providing an auction of goods with variable sales quantity is disclosed. In the system, an auction assisting device stores a non-fungible token (NFT) corresponding to a goods in a block chain network, receives a plurality of bid signals, each of which includes quantity information and price information for the goods, identifies valid bid signals, calculates a total sales amount of a respective valid bid signal by multiplying a sales quantity and a price of the respective valid bid signal, and selects a successful bid signal having a highest total sales amount, determines the sales quantity and the sale price of the successful bid signal as a final sales quantity and a final sale price, determines a successful bidder terminal corresponding to the successful bid signal, and provides the NFT to the successful bidder terminal.

Abstract: A method for mediating virtual asset transmission is provided. The method comprises receiving a first information on virtual asset to be transmitted from a first user to a second user from a first virtual asset service provider (VASP) server managing virtual asset of the first user, transmitting a verification request as to whether information on the second user included in the received first information is correct to a second VASP server managing virtual asset of the second user, receiving a verification result indicating that the information on the second user is correct from the second VASP server as a response to the verification request, and transmitting the received verification result to the first VASP server. The method further comprises transmitting virtual asset update request of the second user to the second VASP server if it is determined that the transaction has been recorded in the blockchain.
