Abstract

The invention relates to a node selection method, a block chain consensus method and device, a system, equipment and a medium, and relates to the technical field of block chains, the node selection method comprises the following steps: obtaining a block hash value of a current latest block in a block chain, and obtaining an initial account address of each node in a consistent hash ring; determining a current candidate node from the consistent hash ring according to the block hash value and the initial account address; judging whether the current candidate node meets a preset condition or not; if yes, taking the current candidate node as a target node, and broadcasting a node selection message in the block chain network by the target node; and if not, selecting a new candidate node as the current candidate node. According to the invention, the service nodes in cloud computing are combined with the nodes in the block chain network to construct a distributed resource service network, and the working nodes in the block chain network are quickly selected by using the randomness of block generation, so that the consumption caused by a large amount of useless computing due to consensus is avoided.

Description

technical field [0001] The present disclosure relates to the technical field of blockchain, specifically, to a node selection method, a blockchain consensus method, a node selection device, a blockchain consensus device, a blockchain consensus system, electronic equipment, and a computer-readable storage medium . Background technique [0002] In the current blockchain technology, most consensus algorithms require all nodes to participate in a calculation game to find a specified random number to prove that they have spent enough computing resources, and the winner of the game can obtain the bookkeeping right and a certain income. This consensus method wastes a huge amount of computing resources and power. At the same time, the block generation speed is slow, and it is prone to low transaction throughput or high delay. It is also impossible to dynamically adjust the block generation speed according to the real-time network pressure. Adjustment. This restricts the applicati...
