DPoS consensus method based on threshold signature and fair reward and system

A consensus and threshold technology, applied in the transmission system, digital transmission system, user identity/authority verification, etc., can solve the problems of lack of incentive mechanism, increased communication overhead between nodes, and poor voting enthusiasm of ordinary nodes, so as to prevent opponents Corruption attack, solve the effect of low voting enthusiasm

Problems solved by technology

[0012] Aiming at the deficiencies of the prior art, the present invention provides a DPoS consensus method and system based on threshold signatures and fair rewards, which can realize a fair reward, decentralized, The advantage of the blockchain consensus system that speeds up the verification speed and greatly increases the transaction volume per second solves the problem of DPoS with only 21 nodes fixedly producing blocks, which leads to serious centralization problems. Since the block rewards are only given to 21 witnesses and candidate nodes , ordinary

Embodiment Construction

[0064] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0065] see Figure 1-5 , a DPoS consensus method based on threshold signatures and fair rewards, including the following steps:

[0066] Step 1. The initial node voting stage. In the voting stage, N (approximately 441) will be selected from the nominated node to enter the witness candidate pool. The specific steps are as follows:

[0067] a. Node self-nomination

[0068] All nodes in the network can self-nominate and register as potential block producers in the community. At this stage, nodes usually set up a campaign website to a...

Abstract

The invention relates to the technical field of DPoS consensus, and discloses a DPoS consensus method based on threshold signature and fair reward, which comprises the following steps: step 1, in an initial node voting stage, a plurality of self-referring nodes can be finally selected to enter a witness candidate pool; step 2, 21 witnesses are selected by using a verifiable delay function; 3, a threshold signature consensus stage is carried out by the witness; step 4; and the award issuing stage is finished by one round of consensus. According to the DPoS consensus method and system based on the threshold signature and the fair reward, a fair reward and decentralized block chain consensus system can be realized without a trusted third party, and the verification speed can be remarkably increased, so that the transaction volume per second is greatly improved.

Description

technical field [0001] The invention relates to the technical field of DPoS consensus, in particular to a DPoS consensus method and system based on threshold signatures and fair rewards. Background technique [0002] Blockchain is a new type of decentralized distributed system that has become popular with the gradual rise of digital cryptocurrencies such as Bitcoin. It has the characteristics of decentralization, time series data, collective maintenance, programmability, safety and credibility. At present, the blockchain has attracted great attention and widespread attention from government departments, financial institutions, technology companies and capital markets. How to efficiently reach a consensus in a decentralized distributed system is an important issue in the research of blockchain technology. [0003] To make the blockchain a decentralized, honest and credible system that is difficult to break, open, and cannot be tampered with data records, it is necessary to m...
