Blockchain allows rapid recognition and response

The method distributes redundant operational and configuration data across multiple servers using a tamper-resistant blockchain.An established statistical baseline of normal voltage, frequency, breaker status, and power quality is used to constantly validate the data and equipment settings.

The settings of the equipment are compared to the most recent good configuration that has been saved in the blockchain at regular intervals.This makes it possible to quickly recognize when, how, and why settings were changed, as well as whether or not those changes were authorized.

According to Borges Hink, “our system helps determine in close to real time whether a fault was triggered by a cyberattack or induced by natural events.”This is the first time that this kind of data validation between a substation, a control center, and metering infrastructure has been done with blockchain.
