摘要： The embodiments of this specification provide a blockchain consensus method, a blockchain consensus device, and an electronic equipment, wherein the method comprises: initiating, by a consensus master node of a blockchain, a consensus proposal for at least one pending-consensus transaction in a transaction pool of the consensus master node, wherein the consensus proposal carries a transaction hash list, and the transaction hash list comprises a transaction hash of the at least one pending-consensus transaction; matching and selecting, by a target consensus backup node of the blockchain from a transaction pool of the target consensus backup node, the at least one pending-consensus transaction corresponding to the transaction hash list, wherein each consensus node of the blockchain has the same transaction hash calculation logic; and obtaining, by the target consensus backup node, transaction information of the matched at least one pending-consensus transaction from the transaction pool of the target consensus backup node, thereby executing a process flow of the consensus proposal based on the transaction information.

摘要： Provided is methods and apparatuses for processing transactions based on a blockchain integrated station. The blockchain integrated station includes a CPU and a smart network card. The smart network card is a network card having a built-in processor or microprocessor and can perform data computing and processing. The smart network card replaces the CPU to actually participate in a blockchain consensus on behalf of the blockchain integrated station and sends a to-be-executed transaction list to the CPU for transaction execution and transaction chaining based on a result of the consensus.

摘要： Embodiments of this specification provide a transaction processing method, apparatus, and electronic device for a blockchain. The method includes: performing, by a blockchain node in the blockchain after execution of a transaction of an N-th round of consensus of the blockchain is completed, a block write operation for the transaction of the N-th round of consensus, where N is a positive integer; and executing, by the blockchain node, an (N+1)-th round of consensus execution operation of the blockchain, where the consensus execution operation includes an (N+1)-th round of consensus of the blockchain and transaction execution after the (N+1)-th round of consensus is reached, and the (N+1)-th round of consensus execution operation is executed concurrently with the block write operation in the N-th round.
