Claim 7:
8. A method for recording data in a process control system using a distributed ledger maintained by a plurality of participants, the method comprising:
obtaining, by a computing device, process plant data related to a process control element within a 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;
generating a transaction, wherein the transaction is stored in the distributed ledger;
generating a cryptographic signature for an entity that generated the process plant data;
augmenting 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;
augmenting the transaction with at least one of: (i) the product parameter data, or (ii) the process parameter data;
transmitting the transaction to at least one other participant in a distributed ledger network of participants maintaining the distributed ledger;
predicting a shelf-life 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.
