Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with specific examples and with reference to the accompanying drawings.

[0031]The present invention proposes a partition fast consensus mechanism suitable for blockchain public chains. The basic idea is divided into two stages: the first stage is to divide a large number of nodes in the global public chain into multiple small partitions, The reputation mechanism in P2P technology is introduced internally, and the Raft algorithm is used to achieve local consensus, which can realize the fault tolerance of malicious nodes; the second stage is to build a global coverage network on top of the partition to achieve the consensus of the entire public chain; for the convenience of nodes An index committee is also set up to store the contact information and reputation value of all nodes in the whole chain;...

Abstract

The invention discloses a partition fast consensus method based on a reputation mechanism in a blockchain. The basic idea of the partition fast consensus method based on the reputation mechanism in the blockchain is divided into two stages: the first stage is to divide a large number of nodes in a global public chain into a plurality of small partitions, introduce the reputation mechanism in the P2P technology inside the partition, and realize local consensus using a Raft algorithm, which can achieve fault tolerance of malicious nodes; and the second stage is to further construct a global overlay network on top of the partitions to achieve the consensus of the entire public chain; in order to facilitate connections among nodes, an index committee is also constructed, which is mainly used to store the contact information and reputation values of all nodes in the whole chain; and all nodes can contact the index committee to find other nodes to establish a connection.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a rapid partition consensus method based on reputation mechanism in block chains. Background technique [0002] Consensus algorithm is a core part of blockchain technology. In the blockchain, nodes that do not trust each other finally achieve data consistency through a preset mechanism, which is called consensus. The essence of consensus is that multiple nodes agree on the data of a certain node or the order of multiple data. The nodes here can be any computer equipment, and the data here can be transaction data, status data, etc. The goals of the consensus mechanism are: 1. The prefix part of the blockchain saved by all honest nodes is exactly the same, that is, consistency. 2. Messages published by honest nodes will eventually be recorded in their own blockchains by all other honest nodes, that is, validity. [0003] So how to evaluate the pros and cons of a consensus m...
