The invention relates to a block chain consensus node selection method and device, computer equipment and a storage medium. The method comprises the steps of broadcasting verification information of the node to other nodes in the block chain, and when a set number of first verification passing information is received, determining the node as a candidate node; and when the node is a candidate node, broadcasting verification information of the candidate node to a plurality of candidate nodes in the candidate node set, and when a set number of second verification passing information is received, determining that the candidate node is a main node. Compared with a traditional method for selecting nodes through proven of rights and interests or a practical Byzantine fault-tolerant algorithm, according to the scheme, multiple rounds of verification are carried out by utilizing verification information formed based on various node information and a verifiable random function, the randomness of node selection is impro
