Block chain consensus method and system based on propagation activeness and asset attestation

Abstract

The invention provides a block chain consensus method and system based on propagation activeness and asset attestation, and the consensus method comprises the following steps: improving the structure of an existing block, and enabling the improved block to comprise a block head, a transaction set and a signature matrix; expanding transaction types on the block chain, wherein the transaction types on the expanded block chain comprise transfer transactions and punishment transactions; and selecting a candidate group by using the signature matrix, determining a final bookkeeper in the candidates according to the number of assets, broadcasting winning information by the bookkeeper, and releasing a new block to the main chain to achieve one consensus. According to the method, invalid resource consumption caused by computing power competition can be avoided, and meanwhile, the bookkeeping right can be prevented from being mastered by hands of a few persons; the propagation delay can be reduced, the message coverage speed of the distributed system is increased, and the possibility of network partitioning is effectively reduced; a self-monitoring function is provided for system safety, and the application requirement of high throughput can be met.

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 messages, there are currently two ideas for improvement: one is to try to reward nodes that forward legitimate messages (in the past, only 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
