Beschreibung
Zusammenfassung:	A distributed transaction ledger (e.g. a blockchain) is used to track and validate changes in a building management system such as a building automation system, access control system, or security/surveillance system. The building management system 100 includes a series of distributed devices connected to a peer-to-peer validation network. The distributed devices generate transaction information during normal operation and broadcast the transaction information to the validation network. The validation network maintains a distributed transaction ledger for the building management system, for example, by validating the transaction information and distributing the transaction information across the validation network according to consensus criteria to be stored locally in multiple instances by nodes of the validation network, which can be dedicated computing devices and/or validator distributed devices. The distributed devices perform building management functions based on validated transaction information retrieved from the transaction ledger.
