The invention discloses a log entry duplication method and device, computer equipment and a storage medium, and belongs to the technical field of block chains. The method includes the steps of parallelly sending multiple first log entries to multiple second nodes; receiving at least one determination response from one arbitrary second node; according to a log index of the second node, determiningat least one second log entry to be supplementarily sent of the second node; sending at least one second log entry to the second node parallelly. Since the first log entries are sent parallelly to thesecond nodes and the first nodes also provide a supplementary sending mechanism of the log entries in order to avoid the situation that reception omission or excessive reception or other log entry reception errors of the second nodes are caused by a network problem, the consistency of node data within a node cluster is ensured, the time for sending the first log entries is saved at the same time,and the efficiency of duplicating the log entries is improved.
