With the discovery and novelty regarding crypto mining farms, it has been foreseen that bitcoin mining and other types of cryptocurrency businesses will flourish in the near future. However, one main issue in smart grid systems is the security regarding data bases that must be addressed. Blockchain has been proven to be a safe alternative to be used in mining systems because it allows a secure applicability in databases and also another important aspect is that each hash in a crypto mining system cannot be changed if it has such an algorithm behind its build. Thus, resulting in a secure and reliable system. The purpose of this paper aims to show how blockchain can affect and be used in a smart power management system going forth from the SealedGrid platform. This system enables the user to monitor in real time the power usage in a smart grid system, in so much that this platform is built to be secure and safe from third-party attacks. Hence this paper shows how a crypto mining application can be applied to an energy saving system.
