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

According to various embodiments, an electronic device including a touch screen display may receive first information associated with a first electronic key of a first door lock, display a first graphic user interface (GUI) associated with the first electronic key to indicate an inactive status of the first electronic key on the display, receive first credential information associated with the first electronic key, and after receiving the first credential information, change the first GUI to indicate an active status of the first electronic key.

Electronic apparatus and operating method thereof

A wearable device includes at least one lens, an output device, at least one sensor, and at least one processor. The at least one processor is configured to identify a level of light sensed through the at least one sensor. The at least one processor is also configured to provide a notification related to the level of the light by using the output device when the level of the light satisfies a preset condition.
