Electronic device using blockchain and control method thereof
A method for controlling an electronic device using blockchain can include transmitting, by a processor in the electronic device, a first transaction to a device account (DA) stored in a distributed server of a blockchain network and logically coupled with the electronic device, the DA including data uniquely identifying the electronic device, transmitting, by the DA, a second transaction to a smart contract, and transmitting, by the DA, device data for controlling an operation of the electronic device to the smart contract. Also, the method can further include receiving, by the DA, data corresponding to a first value according to a transaction rule defined in the smart contract, transmitting, by the DA, the first value to the electronic device, and executing, by the electronic device, a control command corresponding to the first value.
1 . A method for controlling an electronic device using blockchain, the method comprising:
generating and transmitting, by a processor in the electronic device, a first transaction to a device account (DA) stored in a memory;
transmitting, by the DA, a second transaction to a smart contract;

receiving, by the DA, data corresponding to a first value according to a transaction rule defined in the smart contract;
transmitting, by the DA, the first value to the processor; and
executing, by the processor, a control command corresponding to the first value,
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 transaction.
2 . The method of claim 1 , further comprising:
transmitting, by the smart contract, data corresponding to a second value corresponding to the device data to the DA; and
transmitting, by the DA, data corresponding to a third value to the blockchain.
3 . The method of claim 2 , wherein the data corresponding to the first value includes a control command related to at least one of control of the electronic device, playing contents by the electronic device, or obtaining a reward by the electronic device, and
wherein each of the data corresponding to the second value and the data corresponding to the third value includes at least one of cryptocurrency, a token or a digital coin.
4 . The method of claim 1 , wherein the data corresponding to the first value defined in the smart contract varies based on one or more of a type, a screen size, or a resolution of the corresponding to the DA.
5 . The method of claim 4 , wherein the type of the corresponding to the DA includes a shared device or a personalized device.
6 . The method of claim 1 , further comprising receiving a private key of a first user,
wherein the first transaction is created based on the private key of the first user.
7 . The method of claim 1 , wherein the first transaction is created by the itself without user confirmation.
8 . The method of claim 7 , wherein the first transaction is one of a pre-defined set of available transactions.
9 . 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.
10 . The electronic device of claim 9 , wherein the further comprises a display configured to display an image, and
wherein the processor is further configured to:
transmit data corresponding to a second value to the blockchain and play contents, via the display, the contents corresponding to the second value according to the transaction rule defined in the smart contract.
11 . The electronic device of claim 9 , wherein the first transaction is a raw transaction, and the second transaction a transaction based on the raw transaction,
wherein the first transaction is created by the electronic device itself without user confirmation, and
wherein the first transaction is one of a pre-defined set of available transactions.
12 . The electronic device of claim 10 , wherein each of the data corresponding to the first value and the data corresponding to the second value includes at least one of cryptocurrency, a token or a digital coin.
13 . The electronic device of claim 9 , wherein the memory storing the DA is in the electronic device or in the blockchain which is external to the electronic device.
14 . The electronic device of claim 10 , wherein the data corresponding to the first value defined in the smart contract or the data corresponding to the second value defined in the smart contract varies based on one or more of a type, a screen size, or a resolution of the electronic device corresponding to the DA.
15 . The electronic device of claim 14 , wherein the type of the electronic device corresponding to the DA includes a shared device or a personalized device.
16 . The electronic device of claim 9 , wherein the processor is further configured to receive a private key of a first user,
wherein the first transaction is created based on the private key of the first user,
wherein the second transaction is obtained by encoding a signature of the DA into the first transaction.
17 . 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.
18 . The method of claim 17 , further comprising:
transmitting, by the DA, a payment based on the control command to the smart contract; or
receiving, by the DA, a reward based on the control command from the smart contract.
19 . The method of claim 17 , wherein the second transaction is signed by the DA itself without explicit user signature or user confirmation.
