SYSTEMS AND METHODS OF USING A BLOCKCHAIN TO SECURE A BUILDING MANAGEMENT SYSTEM

Abstract:

A building management system having one or more layers of security. The building management system may include building management devices and building management clients configured to be used to access the one or more building management devices. The building management devices and the building management clients may be in communication with one another to form a blockchain network. Individual building management devices and individual building management clients may each be a blockchain node of the blockchain network. In some cases, the building management system may include user accounts through which users access data on the building automation system. The user accounts may be a blockchain node of the blockchain network formed by the building automation system.
