Practical Byzantine fault-tolerant consensus mechanism optimization system for industrial block chain

Abstract

The invention discloses a practical Byzantine fault-tolerant consensus mechanism optimization system of an industrial block chain, which screens out a batch of nodes with higher performance by introducing a reinforcement learning algorithm to screen out block chain network nodes, improves node consensus rules, and optimizes indexes such as block chain network consensus time delay and throughput. Therefore, large-scale application and sustainable development of an industrial Internet system are realized, data tampering is further prevented, data security is ensured, and meanwhile, the expandability and throughput of the system are not affected.

Description

technical field [0001] The invention belongs to the technical field of Internet management, and in particular relates to a practical Byzantine fault-tolerant consensus mechanism optimization system of an industrial block chain. Background technique [0002] The Industrial Internet is an industry and application ecology formed by the all-round and deep integration of the Internet and the new generation of information technology and industrial systems. It is the key comprehensive information infrastructure for the development of industrial intelligence. A service system based on massive data collection, aggregation, and analysis, and an industrial cloud network that supports the ubiquitous connection, flexible supply, and efficient allocation of manufacturing resources are important foundations for my country's manufacturing power and network power. The core of the Industrial Internet is data-driven intelligence based on comprehensive interconnection. Network, data, and securit...

Problems solved by technology

[0006] (1) The operating performance of the original consensus mechanism of the alliance chain is difficult to meet the needs of the industrial Internet system

The PBFT series consensus mechanism has a certain upper limit in terms of performance, and the complexity is too high and the scalability is low

For the mainstream permissioned chain network, when the number of nodes in the consensus system reaches about 20, the performance drops very quickly, and the industrial Internet scenario is a massive interconnection scenario, and the number of connected nodes has been at a high level for a long time, so The existing blockchain network is not suitable for the use requirements of the industrial Internet with multiple access, high concurrency, and low latency scenarios

[0007] (2) The original consensus system of the alliance chain has high requirements for the network environment, and the delay in reaching consensus will be very unstable when the network is unstable

However, in the industrial Internet scenario, the network environment is relatively complex, and the network conditions of the internal network server and the Internet of Things equipment on the external network are quite different. In such a network environment, the conventional alliance chain network will have large fluctuations in the consensus delay, which is not conducive to actual use.
