Problems solved by technology

[0004] The biggest disadvantage of the POW consensus mechanism is that it consumes a lot of resources and wastes energy. In addition, the unbalanced computing power leads to a long consensus cycle. At the same time, the method of simply relying on machine computing power can easily lead to a 51% risk
In essence, the POS consensus mechanism still relies on computing power to increase the proportion of equity, and then obtain the right to bookkeeping, and it is easy to cause nodes with high equity not to participate in b

Abstract

The invention discloses a dynamic Hash computation method and a dynamic Hash computation device for a block chain, a node and a computer readable storage medium. The method comprises the following steps of acquiring an object to be subjected to Hash operation and the height of a block to be generated; converting the height into bytes, and performing the Hash operation on the bytes to acquire a first byte array of a bits; performing n-mode computation on the first m bits of the first byte array according to a preset number of running times m to acquire a second byte array of m bits, wherein n is the type number of preset Hash algorithms; and calling the corresponding Hash algorithm to perform the Hash operation on the object to be subjected to Hash operation according to the Hash algorithmcorresponding to each number and the order of the number in the second byte array, and judging whether the block can be generated according to a computation result. According to the method and deviceprovided by the invention, the Hash algorithm is dynamically generated according to the height of the block, and thus the security of the operation process is ensured.
