[0003] However, several existing single consensus mechanisms have their own problems or defects
[0004] The smart contract consensus method based on the POW mechanism is completely decentralized, and nodes are free to enter and exit, but all nodes in the blockchain network need to verify the correctness of the new block, which occupies most of the computing power of the entire network, thus reducing the cost of the entire network. Calculate ability
The implementation of DPOS is relatively co

Embodiment Construction

[0036] 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 with reference to the accompanying drawings and embodiments. However, it should be understood that the specific embodiments described here are only used to explain the present invention, and are not intended to limit the scope of the present invention. Also, in the following description, descriptions of well-known structures and techniques are omitted to avoid unnecessarily obscuring the concept of the present invention.

[0037] Such as figure 1 As shown, the consensus mechanism method combining DPOS between blockchain node groups and POW within the node group is characterized in that it includes the following steps:

[0038] (a) The Token chain generates a block every 60 seconds, and the 10 node communities rotate to generate new blocks on the Token chain and maintain the transaction chain in rotation, which ...

Abstract

The invention discloses a consensus mechanism method combining DPOS between block chain node groups and POW in the node groups, comprising the following steps: (a) generating node communities in a voting manner, dividing each node community, and after a round robin period is completed, automatically dividing the node communities again by a system, and dividing new node communities again; (b) performing a POW mechanism in the node community where the POW mechanism is switched, wherein each node in the node community competes for an opportunity of generating a Token block, other nodes verify thevalidity of a POW calculation result, and finally, the node with the POW validity generates the node of the Token block; and (c) when the TOKEN chain is bifurcated and the phenomenon that two different blocks have the same parent block due to network delay occurs, solving the bifurcation problem by adopting a method of accepting a longer chain. According to the method, the data packaging verification and chaining process of a large number of parallel block chains can be processed, the computing power of each node in a community is utilized, and decentralization is better than that of a pure DPOS.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a consensus mechanism method combining DPOS among block chain node groups and POW within node groups. Background technique [0002] Smart contracts are an important feature of the blockchain, which can make the blockchain more intelligent. At present, there are four main types of consensus mechanisms in blockchain: Proof of Work (POW) mechanism, Proof of Stake (POS) mechanism, Delegate Proof of Stake (DPOS) mechanism and verification pool ( Pool) mechanism. Among them, the smart contract consensus technology based on the POW mechanism is relatively mature, and its consensus process is: after the node that triggers the transaction broadcasts the transaction request to the blockchain network, all nodes in the network compete to obtain the right to create a new block, and the nodes that succeed in the competition execute After the smart contract broadcasts the generated new block to th...
