An electronic device in an example embodiment includes: a communication circuit configured to transmit and/or receive a signal; a memory configured to store instructions; and at least one processor operatively connected with the communication circuit and the memory. The at least one processor generates a public key regarding a user of the electronic device and a blockchain address; determines an external electronic device to share data; transmits, to the external electronic device through the communication circuit, an invitation message including information regarding the public key and the blockchain address; based on a response message, received from the external electronic device in response to the invitation message, generates a blockchain network including the external electronic device as a node; and stores information regarding the blockchain network in an external server. Various other embodiments that can be understood through the specification are possible.

Electronic device and method for sharing data using blockchain network

An electronic device is provided, which includes a wireless communication module; at least one processor; and a memory configured to store instructions that, when executed by the at least one processor, cause the electronic device to perform a transaction with an external device using the wireless communication module, receive, from a payment server, payment approval information indicating that the transaction is approved, the payment approval information including device information of an access point (AP) located in an offline merchant and period information, establish, in response to receiving the payment approval information, a connection with the AP using the wireless communication module based on the device information of the AP, after the connection with the AP is established, operate a timer corresponding to the period information, and terminate the connection to the AP when the timer expires.

Electronic device and method for supporting automatic Wi-Fi connection with enhanced security method when making electronic wallet payment

An electronic device includes a microphone, a speaker, a processor operatively connected to the microphone and the speaker, and a memory electrically connected to the processor and storing instructions that, when executed by the processor, cause the processor to receive a sound through the microphone, analyze the received sound, determine a song associated with the sound, and a kind of output sound based on at least in part on a result of the analyzing, generate an output sound based on the kind of output sound, and output the generated output sound through the speaker.

Electronic device for outputting sound and operating method thereof

An electronic device is provided and includes a housing; first and second near-distance wireless communication circuits configured to support wireless connection to an access point (AP); a cellular wireless communication circuit; a touchscreen display; a processor connected to the first and second near-distance wireless communication circuits, the cellular wireless communication circuit, and the display; and a memory connected to the processor which stores an application program configured to make payment using the first near-distance wireless communication circuit and instructions which cause the processor to perform a transaction with an external point-of-service (POS) device via the first near-distance wireless communication circuit; receive a result of the transaction comprising receipt information and connection information, the connection information comprising credential information; and connecting to the AP through the second near-distance wireless communication circuit based on the credential information after receiving the transaction result.

A nonvolatile memory device includes a memory cell array including cell strings stacked in a direction orthogonal to a substrate and including a first substring group and a second substring group dividing the cell strings, and an address decoder connected to memory cells of the cell strings via a plurality of word lines and configured to provide operating voltages to the memory cells, wherein the address decoder is disposed between the first substring group and second substring group.

Nonvolatile memory device including multi-plane

An image display device including a main body; a flexible display unit arranged on a front side of the main body; a drive unit arranged on a rear side of the flexible display unit and configured to bend at least one part of the flexible display unit; and a controller configured to search for a user location and control the drive unit to transform the at least one part of the flexible display unit based on the searched user location.
