Embodiment Construction

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be more thoroughly understood, and will fully convey the scope of the present disclosure to those skilled in the art.

[0028] like figure 1 As shown, the blockchain verification node election method proposed by the present invention mainly includes the following steps:

[0029] Step S10, creating a verification node election scheme;

[0030] Step S20, the node applies to become a candidate verification node;

[0031] Step S30, voting for candidate verification nodes, and electing verification nodes;

[0032] Step S40, changing the voting...

Abstract

The invention provides a verification node election method and system of a block chain. The method comprises the following steps: determining an election scheme, an exchange ratio between votes and atime interval; determining a plurality of candidate verification nodes in the candidate verification node list; receiving votes of common nodes, and determining the votes of the candidate verificationnodes based on the exchange ratio of the votes; sorting the plurality of candidate verification nodes based on the votes, and determining a plurality of verification nodes of the next time interval according to the sorting. According to the token and transaction fee fused verification node election scheme provided by the invention, the verification node can be dynamically elected, and the enthusiasm of participating nodes can be aroused. On the premise that the safety is not reduced, the overall processing performance of the block chain is improved, the diversified demands of services are met, the enthusiasm of participating parties is aroused, and healthy operation of a block chain ecological system is maintained.

Description

technical field [0001] The invention relates to the technical field of blockchain, in particular to a method and system for selecting verification nodes of a blockchain. Background technique [0002] Verification node election is the premise and core of the blockchain consensus mechanism. Today's election methods include POW (Proof of Work), POS (Proof of Stake), DPOS (Proof of Share Authorization), DBFT (Delegated Byzantine Fault Tolerance) and so on. Among them, the POW mechanism relies on machine computing power to perform mathematical operations to obtain accounting rights. Compared with other consensus mechanisms, the resource consumption is higher and the supervision is weaker; the fault tolerance of the POS consensus mechanism is the same as that of POW. It is an upgraded consensus mechanism of POW. According to the proportion and time of tokens occupied by each node, the mining difficulty is reduced in equal proportion, thereby speeding up the speed of finding random...
