Block chain consensus method, device and equipment and computer readable storage medium

The embodiment of the invention provides a block chain consensus method, device and equipment and a computer readable storage medium, and the method comprises the steps: building a block chain network of m hierarchies based on a plurality of server nodes, the first hierarchy comprising p units, one unit in the ith hierarchy comprising p units in the (i + 1) th hierarchy, 1 < = i < = m-1, and i, m and p being positive integers; performing forward backtracking to obtain m blocks, and obtaining contents of the m blocks; on the basis of a target random algorithm, the contents of the m blocks are calculated, and m random numbers are obtained; and according to the m random numbers, selecting a server node from the m levels of block chain networks as a block outlet node. According to the block chain consensus method and device, the random number can be generated by adopting the target random algorithm, and the next block outlet node is selected based on the existing block, so that a large amount of computing power i
