Research on multi-end trust based on blockchain in distribution network business

With the continuous deepening of 5G communication application in the field of power Internet of Things, a large number of terminal devices are widely distributed in the distribution network, and a large amount of data needs to be trusted in a relatively short time.The traditional manual inspection method is inefficient and has insufficient safety protection. This paper first analyzes some common consensus mechanisms, and then proposes an improved consensus mechanism, which inhibits the phenomenon of node dishonesty and reduces the hidden danger of data security by means of proof of reputation (PoR).
