A system and method of recording data from a number of devices in a distributed network system in a manner adaptable for auditing the device output. The devices may include one or more control, sensor, edge, or peripheral computing devices physically separate in the distributed network system and in communication with a control server. Such distributed networks systems are common in SCADA or IoT applications. The content stream of data records output from the devices are recorded; a payload stripped stream of data records which are stripped of the payload are recorded and preferably retained by an escrow service. The metadata of the data records includes the hash value of one or more predecessor data records. The hash values are calculated based on the payload and a linkage function, preferably a cryptographic function. A comparison of hash values of the payload stripped stream and the content stream provides the audit ability.
