Claim 21:
22. A non-transitory computer-readable memory coupled to one or more processors and storing instructions thereon that, when executed by the one or more processors, cause the one or more processors to:
receive transactions that include process plant data generated by one or more field devices each performing a physical function to control an industrial process in a process plant, each received transaction including identity data for an entity generating the process plant data, and a cryptographic signature to provide proof-of-identity that the entity generated the process plant data, 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;
store a copy of a distributed ledger;
apply a set of consensus rules to the received transactions;
append one of the received transactions to the copy of the distributed ledger if the received transaction satisfies the consensus rules; and
transmit the appended transaction to at least one peer network node that stores a copy of 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.
