The abstract contains an overview of the patent disclosure:

A method of securing data in an industrial processing facility (IPF) includes creating a private blockchain (PB) using a OPC UA standard functionality and storing the PB in an OPC UA address space adding it to an OPC UA communication protocol framework including edge-nodes coupled to a cloud-based or edge-located data storage. The edge-nodes are PB participant nodes, and a regulator or leader assigns them a single role as a blockmaker, block voter, or observer. The hash in the public ledger is updated once a new block is validated by a majority of the block voters, and the new block is propagated to all PB participant nodes. The regulator, leader or observer utilizes a time bound majority voting consensus to determine whether the PB participant nodes come to a consensus on a current state in the storage medium, and if a consensus the new block added to the public ledger.
