Novel block chain consensus mechanism for intelligent Internet of Things computing power service

Abstract

The invention discloses a novel block chain consensus mechanism for an intelligent Internet of Things computing power service. The novel block chain consensus mechanism comprises a block chain framework for the intelligent Internet of Things computing power service, a matrix product computing task processing mechanism and a reward adjusting mechanism. The block chain framework for the intelligent Internet of Things computing power service comprises four types of nodes: an AIoT node, a coordination node, a miner node and a verification node. A series of matrix product calculation task processing mechanisms proposed by the invention formulate uniform rules and interfaces for block chain miners participating in calculation power service, so that the fairness of block chain mining competition is ensured, more miners can be attracted to participate in the block chain, and the security of a block chain network is further improved. By using the miner distributed computing service in the block chain, the security and privacy leakage risk caused by the central service is reduced, and the security of the computing power service is improved.

Description

technical field [0001] The present invention belongs to the field of block chain and intelligent Internet of things, and is specifically aimed at the problem of waste of miners' computing power caused by the consensus mechanism of proof of work in the existing block chain network, and the computing power faced by intelligent Internet of Things devices for artificial intelligence model training In order to solve the shortage problem, a new blockchain consensus mechanism is designed for intelligent IoT computing service. Background technique [0002] In recent years, blockchain technology has developed rapidly and has been widely used. Among them, the blockchain consensus mechanism is one of the key directions of current research. Through the consensus mechanism, nodes in the blockchain can maintain the security and consistency of transaction records in a distributed system that does not require mutual trust. [0003] The Proof of Work (PoW) consensus mechanism is the earlie...
