Abstract

The invention provides a common father node acquisition method and device based on a block chain system. The method comprises the following steps: symmetrically converting a first node in a dynamic tree into a root node of a tiled tree chain where the first node is located; separating a right child node of a father node of the first node on the auxiliary tree, and taking the first node as the right child node of the father node; symmetrically converting the father node in the dynamic tree into a root node of a tiled tree chain where the father node is located; symmetrically converting an access path from a root node to a second node when the dynamic tree is in the first form into a tree chain where a tree root is located when the dynamic tree is in the first form as a heavy chain, so that the dynamic tree is in a second form; and obtaining a root node of an auxiliary tree where the first node and the second node are located when the dynamic tree is in the second form. According to the invention, the node obtaining efficiency is improved.

Description

technical field [0001] The present application relates to the field of blockchain, in particular to a method and device for acquiring a common parent node based on a blockchain system. Background technique [0002] In the blockchain system, it is difficult to avoid forks. When a new block of a forked chain is received, it is necessary to return to the fork point and select the main chain again according to the rules. At this time, it is necessary to obtain the common parent node of the two block nodes and perform calculations from the common parent node. Currently commonly used methods for obtaining common parent nodes, such as the backtracking method, are not efficient and require a large amount of calculation, which affects the overall performance of the blockchain. Contents of the invention [0003] In order to solve one of the above technical problems, the present invention provides a method and device for acquiring a common parent node based on a blockchain system. ...
