Problems solved by technology

[0005] There are many problems in the above-mentioned consensus algorithm. Simply put, the POW election is responsible for generating block nodes, which consumes a lot of resources and has low transaction performance.
POS, DPOS, POI, POP, and Raft mainly increase the transaction volume by reducing the number of nodes responsible for generating blocks, but the way of electing nodes responsible for generating blocks is either that the credibility is not high, or the computing power of the nodes is not concerned question

Abstract

The invention discloses a consensus node selection method and device, and the method comprises the steps: classifying consensus nodes in a blockchain network selectable consensus node pool, and obtaining three types of consensus nodes; obtaining log data of the block chain network, and determining a weight index corresponding to each consensus node according to the log data; inputting the weight index corresponding to each consensus node into a pre-established weight calculation model to obtain a node weight value corresponding to each consensus node; and according to the node weight value corresponding to each consensus node, performing consensus node selection from the three types of consensus nodes according to the obtained node selection rule. By classifying the consensus nodes and setting the weight values, reasonable selection of the block chain network consensus nodes is realized, the influence of excessive nodes on the consensus efficiency and transaction processing performance on the block chain network is avoided, the credit of generating the block nodes is improved, the method can be suitable for different application scene requirements, and intelligent data decision of consensus node selection is realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and device for selecting a consensus node. Background technique [0002] The consortium chain is a blockchain that is jointly managed by multiple organizations or institutions, and each organization or institution contributes and manages one or more consortium chain nodes. With the increase of joining organizations or institutions, the number of alliance chain blockchain network nodes gradually increases. At present, the number of nodes in the consortium chain blockchain network will affect the transaction processing performance. The more nodes there are, the lower the transaction processing performance will be. In the context of the current blockchain technology, high TPS and decentralization are basically irreconcilable contradictions, and complete centralization and complete decentralization are also ideal states. For this reason, real financial application sce...
