Claim 15:
16. A system for recording data in a process control system using a distributed ledger maintained by a plurality of participants comprising:
one or more devices disposed in a process plant each performing a physical function to control an industrial process; and
a computing device executing in the process plant including:
one or more processors;
a communication unit; and
a non-transitory computer-readable medium coupled to the one or more processors and the communication unit and storing instructions thereon, that when executed by the one or more processors, cause the computing device to:
obtain process plant data related to the one or more devices within the process plant, the process plant data including at least one of: (i) product parameter data including characteristics of a product manufactured at the process plant, or (ii) process parameter data for a process plant entity that contains, transforms, generates, or transfers physical materials within the process plant;
generate a transaction;
generate a cryptographic signature for an entity that generated the process plant data;
augment the transaction with identity data for the entity and the cryptographic signature to provide a proof-of-identity that the entity generated the process plant data;
augment the transaction with at least one of: (i) the product parameter data or (ii) the process parameter data; and
transmit the transaction to at least one other participant in a distributed ledger network of participants maintaining the distributed ledger for validating and recording the transaction in the distributed ledger,
wherein a shelf life of a product is predicted by assigning a quality score to each of a plurality of components of the product using the product parameter data or the process parameter data included in the distributed ledger for the product.
