Abstract

The invention relates to a method and device for electing nodes in a block chain network, a block chain system and a computer program product, the block chain network comprises a plurality of consensus nodes, and the plurality of consensus nodes comprise a proposal node responsible for block proposal and other nodes. The method comprises executing the following operations at other nodes: receiving i-th block proposal information sent by a proposal node of an i-th block, wherein the i-th block proposal information comprises a proof set of an (i + 1)-th block; extracting a proof set of the (i + 1) th block from the proposal information of the ith block; and determining a proposal node of the (i + 1) th block based on the proof set of the (i + 1) th block and the attribute information of the plurality of consensus nodes, i being an integer greater than zero, and the (i + 1) th block being a next adjacent block of the ith block. Through the technical scheme of the invention, the security of the block chain consensus algorithm can be effectively improved.

Description

technical field [0001] The present invention generally relates to the field of blockchain technology. More specifically, the present invention relates to a method, device, blockchain system and computer program product for electing nodes in a blockchain network. Background technique [0002] This section is intended to provide a background or context for implementations of the invention that are recited in the claims. The descriptions herein may include concepts that could be explored, but not necessarily concepts that have been previously thought of or explored. Therefore, unless otherwise indicated herein, what is described in this section is not prior art to the description and claims in this application and is not admitted to be prior art by inclusion in this section. [0003] The blockchain system is a decentralized distributed accounting system, and the blockchain consensus algorithm is the core part of the blockchain system. Generally, the blockchain consensus algo...
