According to an embodiment of the present disclosure, the preset consensus node may include all consensus nodes.
According to the embodiment of the disclosure, under the condition that the preset consensus nodes comprise all the consensus nodes, the resource transfer description information can be ensured to be verified by as many consensus nodes as possible, so that the safety of data is improved, however, if all the consensus nodes need to perform consensus calculation on the resource transfer description information, excessive calculation power is consumed.
According to an embodiment of the present disclosure, the preset consensus node may include a consensus slave node and a plurality of consensus master nodes.
Responding to the consensus information returned by the preset consensus node, and generating a consensus result according to the consensus information comprises the following steps:
and responding to the consensus master node to return the consensus information, and generating a consensus result according to the consensus information.
According to the embodiment of the disclosure, a plurality of consensus master nodes can be selected from the consensus nodes in an election mode or the like, the consensus master nodes can perform consensus calculation on behalf of the consensus slave nodes, and then only the consensus master nodes return the consensus information to the target consensus nodes.
According to the embodiment of the disclosure, the common master node is selected by all the common nodes, so that excessive calculation force can be prevented from being consumed on the basis of ensuring the validity of the common information.
According to an embodiment of the present disclosure, the consensus master node may be determined by determining the number of blocks that have been found in the blockchain, determining the number of consensus nodes included in the blockchain system, determining a remainder result obtained by dividing the number of blocks that have been found by the number of consensus nodes, and determining a target consensus node number, wherein the target consensus node number is a consensus node number equal to the remainder result, and determining a consensus node corresponding to the target consensus node number as the consensus master node.
According to the embodiment of the disclosure, the consensus master node is not fixed and can be reelected according to actual conditions. I.e. if the consensus master node fulfils the re-election condition, a re-election operation may be performed. Wherein the re-election condition may include whether the blocking request is terminated within a preset period of time. The re-election condition may be indicated as being satisfied if the blocking request is terminated within a preset period of time, and may be indicated as being not being satisfied if the blocking request is not terminated within the preset period of time. Wherein the blocking request may be terminated because of a failure of the consensus master itself and/or an interruption of the communication connection between the consensus master and other consensus nodes.
According to the embodiments of the present disclosure, in an actual resource transferring process, there may be a situation that a resource is transferred to an erroneous resource receiving party due to untimely information update, for example, in an application scenario that a resource is transferred to wage, a wage issue list may need to be updated once in a quarter or half a year, however, in a wage issue list update period, there may be a situation that staff is away from duty, in which case wage is issued to the staff that has been away from duty if wage issue is still performed according to a preset wage issue list, and thus verification information needs to be checked.
