Abstract

A method of building a device historian, across a supply chain of device manufactures and managers, by a plurality of device management services comprising an enrollment service, an update service, a policy service, and an analytics service, a transaction connector, a blockchain broker service participating as a node in a blockchain network, and transaction filters. The method comprises sending, by the plurality of device management services a transaction record over the transaction connector to the blockchain broker service, receiving, by the blockchain broker service, the transaction record, filtering, by the blockchain broker service, information in the transaction record based on the transaction filters, preparing, by the blockchain broker service, a versioned block based on the filtered information from the transaction record, and adding, by the blockchain broker service, the versioned block to the blockchain network.
