Blockchain-based entrusting right proof consensus method and device

Abstract

The embodiment of the invention provides a blockchain-based entrusting right proof consensus method and device. The method comprises the steps: electing candidate bookkeeping persons and current bookkeeping persons based on weights in nodes participating in bookkeeping; after the candidate bookkeeper and the current bookkeeper finish election, keeping an account by the current bookkeeper; after bookkeeping is finished, sending a message to notify other verification pools to verify the bookkeeping result, and executing a corresponding reward and punishment mechanism on the bookkeeping person in the current period according to the verification result; and performing sorting operation according to the weights of the candidate bookkeeping persons, and selecting the candidate bookkeeping person ranking the first as a new bookkeeping person. According to the embodiment of the invention, the current-period bookkeeper and the current-period candidate bookkeeper are elected based on the weights, so that the problem that the terminal nodes cannot vote in time can be avoided, and malicious nodes can be effectively eliminated by comparing the difference of the bookkeeping results of each bookkeeping terminal; and considering the rights and interests of each bookkeeping terminal during reward and punishment design of the bookkeeper in the current period, so that the enthusiasm of each bookkeeping terminal in the verification pool to participate in bookkeeping can be stimulated.

Description

technical field [0001] The present invention relates to the technical field of block chains, and more specifically, to a block chain-based entrusted proof of rights consensus method and device. Background technique [0002] The Delegated Proof of Stake (DPOS) consensus algorithm (Delegated Proof of Stake, DPOS) was proposed by Daniel Larimer (BM) in 2014. The blockchain based on the Delegated Proof of Stake has a voting system, and stakeholders deliver their work to third parties. Change In other words, they can vote for several representatives to protect the network instead of them. Representatives are also called witnesses, and they are responsible for reaching a consensus in the process of generating and verifying new blocks. Voting rights are related to the number of coins held by each user Proportional, the voting system also varies from project to project. But in general, each delegate presents an individual proposal when asked to vote. Usually, delegates also collect ...

Problems solved by technology

However, the DPOS algorithm still has unavoidable bottlenecks when dealing with a large number of nodes. For example, nodes cannot vote in time, and malicious nodes cannot be eliminated in time, resulting in too long response time.
