In a Blockchain-backed supply chain, how do people ensure companies don’t tamper with the actual sensors?




I get that if you have sensors along the supply chain, you can ensure where/when a product arrived, the temperature of the room etc… but all that data is sent to the blockchain via a sensor that the company has access to. Whats stopping the company from modifying or tricking the sensor into always giving good readings, even if something goes wrong?

e.g. If a truck is transporting a Vaccine that needs to stay below a certain temperature, couldn’t the company rig some temperature hack to always keep the sensor cold even though the surrounding areas might turn warmer than allowed?

Also, how on earth does this work when tracing minerals in a mining supply chain? https://www.rcsglobal.com/blockchain-traceability/

If sensors can’t measure temperature.. what are they measuring?
