Electronic device using blockchain and control method thereof

An electronic device using blockchain, the electronic device comprising:

• a memory configured to store a device account (DA);
• a transceiver configured to transmit and receive data;
• and
• a processor configured to:
• transmit a first transaction to the DA stored in the memory,
• transmit a second transaction to the blockchain for establishing a smart contract, the second transaction being based on the DA stored in the memory,
• transmit device data to the blockchain, the device data being related to an action of the electronic device, and
• receive data corresponding to a first value according to a transaction rule defined in the smart contract,
• wherein the DA is a software wallet within the blockchain that is logically coupled with the and includes data uniquely identifying the electronic device.

A method for controlling an electronic device using blockchain, the method comprising:

• generating and transmitting, by a processor in the electronic device, a first raw transaction to a device account (DA) stored in a memory;
• transmitting, by the DA, a second transaction to a smart contract stored on the blockchain, the second transaction being based on the first raw transaction;
• transmitting, by the DA, device status data for controlling an operation of the electronic device to the smart contract;
• receiving, by the DA, a control command based on a transaction rule defined in the smart contract;
• transmitting, by the DA, the control command to the processor;
• and
• executing, by the processor, the control command,
• wherein the DA is a software wallet within the blockchain that is logically coupled with the and includes data uniquely identifying the electronic device, and
• wherein the second transaction is obtained based on encoding a signature of the DA into the first raw transaction.
