method for submitting transaction information and device for submitting transaction information

摘要

The present invention relates to implementations that describe a method and a device for sending transaction information and performing consensus verification. If another consensus node fails to receive transaction information sent through a handling node in a transaction handling phase, the other consensus node may send a consensus verification failure notification that includes a transaction information identifier. handling node in a consensus check phase, if the other consensus node determines that transaction information included in a preprocessed block does not exist in a transaction set of another consensus node, so that the handling resends transaction information to the other consensus node. According to the implementations of this application, it can be ensured as far as possible that transaction information stored in consensus node transaction sets is consistent and therefore the accuracy of a consensus node consensus check result. consensus is not reduced.
