Embodiment Construction

[0026] Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals designate the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0027]In the blockchain system under the existing DPOS consensus mechanism, the selection of block production nodes is realized through voting. However, because voters cannot always pay attention to the production block status of each node, they do not vote in time, and the default is to follow the previous one. Vote according to the voting results, or vote for nodes that are often offline. In the implementation method of the consensus mechanism of the blockchain system provided by the embodiment of the present invention, when th...

Abstract

The invention proposes a method for implementing a consensus mechanism of a blockchain system. The method comprises the following steps: creating a system node weight table when the blockchain systemis initialized; when the current production node in the blockchain system is producing a block, querying the ip address of each node according to the system node weight table to determine whether there is a dropped node in the blockchain system; if there is a dropped node, decrementing the node weight value of the dropped node by 1, and updating the system node weight table; and when production nodes are generated based on the dpos consensus mechanism, selecting production nodes according to the number of votes of each node and the node weight value of each node. Therefore, the method providedby the invention links the offline time of the nodes with the statistical weight of the node voting number, so that even if the nodes that are frequently dropped have a high number of votes, the statistical weight of the voting number is not too high, thereby greatly reducing the possibility that the nodes that are often dropped become block production nodes, and ensuring that the blockchain system operates efficiently.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a method, medium, device and system for realizing a consensus mechanism of a block chain system. Background technique [0002] The blockchain is essentially a deterministic state machine driven by transactions. Consensus is the process of agreeing on a deterministic transaction sequence and filtering invalid transactions. The compelling security of DPOS (Delegated Proof of Stake) comes from Its algorithm for selecting the quality of block producers and validators. In the blockchain system under the existing DPOS consensus mechanism, the selection of block production nodes is realized through voting. However, because voters cannot always pay attention to the production block status of each node, they do not vote in time, and the default is to follow the previous one. Vote according to the voting results, or vote for nodes that are often offline. Contents of t...
