Abstract

The invention discloses a blockchain consensus method and device based on Raft algorithm, relates to the field of communication technology, and is used to solve the problem that abnormal nodes in the blockchain based on Raft algorithm in the prior art are easily elected as candidates and the node activity is relatively high. Low technical problems that lead to lower security of the blockchain system. The present invention can build consensus nodes in the blockchain and build a supervisor node for obtaining the node information of each consensus node, and obtain the node information of each consensus node including block height, online duration, and average number of votes through the supervisor node. , when the term of the consensus node in the leader state ends, the consensus node in the leader state receives the node information of each consensus node sent by the supervisor node, and determines and broadcasts to at least one recommended candidate consensus node according to the above node information. The state of the consensus node is converted to the candidate state, and the next term election process is entered. The present invention is used to improve the security of the blockchain 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...
