Digital electronic device based on dual blockchain having virtual blockchain and operation method thereof

An operation method of a digital electronic device based on a dual blockchain having a virtual blockchain, comprising:

• a step in which a query controller receives a request and a communication device token for a transaction from a blockchain network;
• a step in which a token validator validates the communication device token based on information available in a physical blockchain or a virtual blockchain;
• a step of determining whether the communication device token is successfully validated;
• a step in which a processor outputs an operation control signal for controlling an operation of a digital electronic device when the communication device token is successfully validated;
• a step of allowing a transaction based on successful validation of the communication device token;
• a step in which a token generator generates an updated communication device token;
• and
• a step in which a virtual node generator duplicates a virtual node and adds the duplicated virtual node to a redundancy area in the digital electronic device according to a duplication command of the processor when the validation of the communication device token fails.
