Provided is a method and apparatus for synchronizing data based on a blockchain integrated station. The blockchain integrated station includes a CPU and an intelligent network card. The intelligent network card is a network card having a built-in processor or microprocessor to perform data computation and processing. The intelligent network card can replace the CPU to perform data synchronization inquiry and to-be-synchronized block data pulling, and the CPU performs data synchronization based on the to-be-synchronized block data sent by the intelligent network card.
