1. An auditor system for a building management system environment comprising:
a blockchain component configured to provide communication between the auditor system and blockchain components of other systems of a network of peer-to-peer nodes, the network of peer-to-peer nodes validating and securing a decentralized ledger of transaction records and being synchronized by the decentralized ledger using proof of work, the transaction records of the decentralized ledger being immutable;
a processor configured to provide interaction between the auditor system and the other systems of the network of peer-to-peer nodes, and process building information associated with a selected remediation type received from the blockchain component and requirement for regulatory compliance by one or more auditors associated with a regulator agency; and
a memory component configured to store a local ledger of the auditor system,
wherein the blockchain component accesses transaction records of a decentralized ledger relating to remediation types of the building automation system,
wherein the processor reads a first transaction record of a first system and a second transaction record of a second system in the decentralized ledger relating to the remediation type, performs an audit of the first transaction record and the second transaction record of the decentralized ledger relating to the remediation type, and replicates the first transaction provided by the first system and the second transaction record provided by the second system at the local ledger of the auditor system,
and
wherein the processor performs the audit of the first transaction record and the second transaction record of the decentralized ledger relating to the remediation type without providing any new transaction records to the decentralized ledger that relate to the remediation types of the building automation system and do not relate to the audit.
