ELECTRONIC TERMINAL DEVICE THAT ENABLES UPDATE PROCESSING FOR APPLICATIONS AND FORGERY DETECTION OF UPDATE DATA BASED ON BLOCKCHAIN AND OPERATING METHOD THEREOF

摘要

The present invention receives update data propagated from an update data management server through a block chain network, redistributes it to other node devices through the block chain network, and sends the update data to a new node device newly participating in the block chain network. In the case of distribution, update processing and update for application applications based on the block chain by propagating the snapshot data including all past update data and the block in which the hash value thereof is inserted to the new node device An electronic terminal device capable of detecting forgery of data and an operating method thereof.
