Problems solved by technology

[0008] The current consensus method is not perfect and cannot adapt to all application scenarios, especially when the number of network nodes is large or there are multiple subnets, it is necessary to design a targeted consensus method to improve the efficiency of consensus and reduce network traffic

Embodiment Construction

[0024] It is easy to understand that according to the technical solution of the present invention, without changing the essential spirit of the present invention, those of ordinary skill in the art can imagine multiple implementations of the layered consensus method and system of the blockchain of the present invention. Therefore, the following specific embodiments and drawings are only exemplary descriptions of the technical solutions of the present invention, and should not be regarded as all of the present invention or as a limitation or limitation to the technical solutions of the present invention.

[0025] The technical scheme of the present invention groups the computer nodes participating in the consensus in the entire network, and divides the entire network into a backbone network and multiple independent sub-networks. The backbone network is the first layer of the consensus, and each sub-network is the second layer of the consensus. Floor. The process of reaching consen...

Abstract

The invention relates to a hierarchical consensus method and system for a block chain. Computer nodes participating in consensus in the whole network are grouped, the whole network is divided into a backbone network and a plurality of mutually independent sub-networks, the backbone network is a first layer of the consensus, and each sub-network is a second layer of the consensus; the process of achieving consensus by the nodes in the block chain network is realized through a layered strategy, the nodes in the first layer of backbone network firstly form the consensus, and the nodes in the second layer of subnetwork synchronously form the consensus. Due to the fact that the number of the nodes in the backbone network is greatly reduced compared with the number of the nodes in the whole network, when the number of the nodes in the whole network is large, the block chain system can still achieve consistency efficiently, and network bandwidth occupation is smaller.

Description

Technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a layered consensus method and system of block chains. Background technique [0002] Blockchain is a decentralized distributed database technology involving all nodes. The information recorded in the blockchain network is jointly recorded by all verification nodes, without any centralized node review, and the recorded information has the characteristics of unforgeable and tamper-proof. Complete traceability, decentralization and de-credit are the three characteristics of blockchain technology. The blockchain does not have a central organization, and the consistency of the information of each node is guaranteed through the consensus mechanism of the blockchain. The blockchain consensus mechanism is a communication model that transmits and synchronizes data based on the Byzantine fault-tolerant distributed consensus algorithm and according to specific business scenari...
