An electronic device is provided. The electronic device includes a communication module, a memory for storing instructions, and a processor, wherein the processor is configured to execute the instructions such that the electronic device identifies owner information of first content in response to a content ownership transfer request, transmits, to a blockchain network, transaction data for transferring the ownership of the first content, on the basis of the owner information of the first content, and transmits the first content to an external electronic device, wherein the transaction data may be regarding a transaction of transferring the ownership of a token related to the first content.

Electronic device for managing right by using decentralized network, and operation method thereof

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 constituting a first block node included in a blockchain network of the disclosure is provided. The electronic device performs, in response to an input of requesting a transaction, obtaining first input data, output data, and a first identification value indicating a unique value capable of identifying a first smart contract, validating a blockchain application, forwarding a public key for a private key and an input data request to the second block node, based on the validation result, receiving, from the second block node, second input data encrypted with the public key and a second identification value indicating a unique value capable of identifying a second smart contract, and transmitting transaction data including the first input data and the output data to the server node, based on the comparison result of the first identification value and the second identification value.

Electronic device for providing transaction in blockchain network and operating method thereof

An electronic device is provided. The electronic device includes a display, and a processor configured to generate at least one hierarchy deterministic path, obtain at least one public key using a root seed and the at least one hierarchy deterministic path, obtain a blockchain address for a blockchain account from the at least one public key, obtain information about the blockchain address from a blockchain network based on the blockchain address, the information about the blockchain address including information about a balance of the blockchain account, and display at least part of the information about the blockchain address through the display, based on the information about the balance of the blockchain account.
