Example Embodiment

[0043] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] The embodiment of the present invention provides a lightweight probability verification method in a blockchain, the verification method is applied to each node in the blockchain, so that when each node acquires a broadcasted block, based on a random probability And the current verification degree, decide whether to select the verification of the block, so that some nodes receive the block after verifying the block, and some nodes directly

Abstract

The invention discloses a lightweight probability verification method and device in a block chain, a block chain node and a medium. The method comprises the following steps: acquiring a current block of broadcast transmission; generating a random probability, and obtaining a current verification degree corresponding to the current block; if the random probability is smaller than the current verification degree, verifying the current block, and storing the current block in a node local chain; and if the random probability is not less than the current verification degree, directly storing the current block in a node local chain. According to the method, the data security in the block chain network can be ensured, and the propagation delay of the current block in the block chain network can be slowed down, so that the block chain bifurcation phenomenon is reduced.
