Blockchain consensus method and system based on communication activity and asset certification

Abstract

This application provides a block chain consensus method and system based on communication activity and asset certification. The consensus method includes the following steps: improving the structure of the existing block, and the improved block includes block header, transaction set and signature Matrix; expand the transaction types on the blockchain. After the expansion, the transaction types on the blockchain include transfer transactions and penalty transactions; use the signature matrix to select the candidate group, and determine the final bookkeeper among the candidates according to the amount of assets , the bookkeeper broadcasts the winning information and releases a new block to the main chain to reach a consensus. This application can avoid the waste of invalid resources caused by computing power competition, and at the same time, it can avoid the power of bookkeeping in the hands of a few people; it can reduce the propagation delay, speed up the message coverage speed of the distributed system, and effectively reduce the possibility of network partition; Provides self-monitoring function for system security, which can meet the application requirements of high throughput.

Description

technical field [0001] This application belongs to the field of blockchain technology, and specifically relates to a blockchain consensus method and system based on communication activity and asset certification. Background technique [0002] Since the birth of the first blockchain application known as Bitcoin in 2009, the value exchange and storage characteristics of the blockchain have been well known. The consensus mechanism has solved the most challenging problems in the blockchain. That is, in a distributed environment, under the joint maintenance of many nodes, the consistency of the system state is achieved. Specifically, the consensus mechanism can be interpreted as a consistent execution result of a change in a distributed network, or to maintain normal work when a node fails. With the continuous expansion of application scenarios, the consensus mechanism is gradually divided into two types according to the different entry thresholds of nodes. One is a probability...

Problems solved by technology

In order to reduce the propagation delay of the message, there are currently two ideas for improvement: one is to try to reward the nodes that forward legal messages (in the past, only the nodes that keep accounts can get block rewards), but this incentive method will greatly increase the block rewards. block reward overhead; the other is to simplify the verification steps when nodes forward messages from the perspective of the client, and shorten the objectively required network delay, but this method has little effect on reducing delay and does not fundamentally Resolutely spread the issue of low activity
