Fuente: Wipo "Sensorization" An industrial machine predictive maintenance system may include an industrial machine data analysis facility that generates streams of industrial machine health monitoring data by applying machine learning to data representative of conditions of portions of industrial machines received via a data collection network. The system can utilize a distributed ledger to track one or more transactions executed in an automated data marketplace for industrial Internet of Things data. The distributed ledger distributes storage for data indicative of the one or more transactions across one or more devices, wherein the data indicative of the one or more transactions corresponds to transaction records. A transaction record stored in the distributed ledger represents one or more of sensor data, the condition of an industrial machine, orders or the requests for service and parts, an issue associated with the condition of a machine, or a hash used to identify the transaction record.
