NODE DEVICE THAT CAN IMPROVE TRANSACTION PROCESSING SPEED BY PROPAGATING TRANSACTIONS BEFORE GENERATING BLOCKS IN A BLOCK-CHAIN NETWORK AND OPERATING METHOD THEREOF

摘要

Disclosed is a node device capable of improving a transaction processing speed by propagating a transaction before generating a block in a blockchain network, and a method of operation thereof. In the present invention, when a storage event for storing the first transaction data in the blockchain network occurs in a specific node device, the specific node device generates a first transaction including the first transaction data, and then performs the remaining first transaction. By sequentially propagating to node devices, each node device updates its own ledger database based on the first transaction so that the processing of the first transaction is preferentially completed in each node device, and then the When the processing of the first transaction is completed, the block including the first transaction is registered in the blockchain network through a predetermined anchor node device, thereby improving the processing speed of the transaction in the blockchain.
