Abstract: Provided in the embodiment of the present disclosure is a method for monitoring a state of a blockchain consensus node, including that: an address list of all consensus nodes of a blockchain is acquired; the number of produced blocks and the number of times of voting of the consensus nodes in the produced blocks within a preset time period are recorded; a voting monitoring index of each consensus node is calculated, wherein the voting monitoring index includes at least one of a voting rate and a voting proportion; and in response to the voting monitoring index of the consensus node being lower than a preset alarm threshold, an abnormal state alarm in respect of the corresponding consensus node is issued.
