Abstract
Computer-implemented methods, apparatuses, and system for processing transactions using a blockchain integrated station are provided. The blockchain integrated station includes a central processing unit (CPU) and an intelligent network card. The intelligent network card includes a processor different from the CPU. The intelligent network card is coupled with one or more caches. The blockchain integrated station serves as a blockchain node of a blockchain network. The intelligent network card is configured to receive a transaction of the blockchain network; identify the transaction as a replay transaction by operations comprising: comparing the transaction with historically received transactions in the one or more caches; and in response to a comparison result indicates that the transaction is the same as one of the historically received transactions, determining the transaction as a replay transaction.
