Abstract

Disclosed herein is an apparatus and method for synchronizing a block in a blockchain network. The apparatus synchronizes node information of existing participating nodes connected to a blockchain network by joining the blockchain network, determines synchronization target blocks by calculating the current section of a blockchain using an agreed-upon block received from the existing participating nodes, receives a block header of each section and the segment hash table of a snapshot that are verification data for verifying synchronization target data for the synchronization target blocks from participating nodes that are not connected as peers, among the existing participating nodes, generates a snapshot by receiving snapshot segments and the blocks of the current section, which are the synchronization target data, from participating nodes connected as peers, among the existing participating nodes, verifies the snapshot generated from the snapshot segments, and synchronizes the verified snapshot.
