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.
