  • Building device with blockchain based verification of building device files
    Patent number: 11398896
    Abstract: A building device of a building includes or is in communication with a processing circuit configured to store one or more files, each of the one or more files comprising instructions and a ledger, the ledger comprising information describing at least one of the one or more files. The processing circuit is configured to verify the one or more files by retrieving a root ledger from storage of the processing circuit, wherein the root ledger comprises information based on one or more characteristics of a blockchain, reassembling the blockchain based on the ledger of each of the one or more files, verifying the blockchain with the root ledger, and verifying the one or more files with the verified blockchain. The processing circuit is configured to execute the instructions of the one or more files in response to a determination that the one or more files are verified.
