Computer-implemented methods, apparatuses, and systems for transferring a transaction using a blockchain integrated station are provided. The blockchain integrated station includes a central processing unit (CPU) and a smart network card. The smart network card is configured to receive a transaction of a blockchain network, wherein the blockchain integrated station is a blockchain node of the blockchain network, and determine other blockchain nodes in the blockchain network; and in response to determining the other blockchain nodes of the blockchain network, transfer the transaction to the other blockchain nodes of the blockchain network.

Methods and apparatuses for transferring transaction based on blockchain integrated station

Computer-implemented methods, apparatuses, and systems are provided for synchronizing data based on a blockchain integrated station. 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 blockchain integrated station serves as a blockchain node of a blockchain network, and the intelligent network card is configured to inquiry other blockchain nodes of the blockchain network on whether there is to-be-synchronized block data; in response to determining that there is the to-be-synchronized block data, pull the to-be-synchronized block data from the other nodes of the blockchain network; and provide the to-be-synchronized block data to the CPU.

A cryptographic acceleration card generates, using an attribute unique to a blockchain integrated station that comprises the cryptographic acceleration card, an identity private key for the blockchain integrated station. The cryptographic acceleration card generates a private key ciphertext by encrypting the identity private key. The cryptographic acceleration card stores the private key ciphertext.

Blockchain integrated station and cryptographic acceleration card, key management methods and apparatuses

Computer-implemented methods, apparatuses, and systems for identifying a to-be-filtered transaction using a blockchain integrated station are provided. The blockchain integrated station includes a central processing unit (CPU); and a smart network card. The smart network card includes a processor different from the CPU. The smart network card is configured to receive a transaction of a blockchain network, wherein the blockchain integrated station is a blockchain node of the blockchain network, and identify a transaction by operations comprising determining whether the transaction satisfies a predetermined filtering condition; and in response to determining that the transaction satisfies the predetermined filtering condition, determining the transaction as a to-be-filtered transaction.
