Abstract

The invention discloses a block chain consensus method and device based on a Raft algorithm, relates to the technical field of communication, and is used for solving the technical problems that in theprior art, abnormal nodes in a block chain based on a Raft algorithm are easily selected as candidates, and the node activity is relatively low, so that the security of a block chain system is relatively low. According to the invention, the consensus nodes and the supervisor nodes used for obtaining the node information of the consensus nodes can be constructed in the block chain; the height of each consensus node including the block height, Online duration, and node information of the average voting frequency are obtained through the supervisor node; when the consensus node of the leader state ends at any time, the consensus node of the leader state receives the node information of each consensus node sent by the supervisor node, determines and broadcasts the node information to at mostone recommended candidate consensus node according to the node information, converts the state of the recommended candidate consensus node into a candidate state, and enters a next election process. The invention is used for improving the security of the block chain system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a block chain consensus method and device based on Raft algorithm. Background technique [0002] At present, the common consensus mechanisms of blockchain include POW mechanism, POS mechanism and DPOS mechanism. The above mechanisms have drawbacks in terms of resource consumption, security, and consensus time. For example, the resource consumption of the POW mechanism is relatively large. Each time a consensus is reached, the entire network needs to participate in the calculation, which takes a certain amount of computing time and has low performance efficiency; the POS mechanism and the DPOS mechanism are determined according to the system token or weight held by the user The probability of generating blocks, but it does not maintain the ecology and security of the blockchain system itself. Based on the above existing problems, the patent No. 201710062689.4 prop...
