Patent attributes
Embodiments of this specification provide transaction confirmation methods and apparatuses. An example method includes: in response to detecting an event indicating that one of multiple nodes has persistently stored a batch of transactions or executed transactions of a subbatch of transactions, determining a current latest subbatch of subbatches of transactions for which the multiple nodes have confirmed; determining a target subbatch according to the current latest subbatch; determining a first quantity of the multiple nodes that have generated execution results that are consistent with an execution result of the target subbatch; determining a second quantity of the multiple nodes that have persistently stored a target batch to which the target subbatch belongs; and in response to the first quantity and the second quantity both meeting a consensus fault tolerance, determining that transactions in the target subbatch are confirmable transactions.
