Abstract: 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.

Abstract: An electronic device includes a communication circuit and a processor connected to the communication circuit. The processor may be configured to generate first transaction data comprising a first piece of transaction data for transferring a part of unused transaction output values of a first address from the first address to a second address, transmit the first transaction data to a server, receive status information indicating a transmission delay status of the first transaction data in a blockchain network from the server, receive recommendation fee information on transmission of the first transaction data, from the server, and generate second transaction data comprising a second piece of transaction data for transferring the part of the unused transaction output values of the first address from the first address to the second address, based on the recommendation fee information.
