I am a university student studying Ethereum in South Korea. It is not a regular course but a personal study due to interest!
I would like to make a conceptual diagram of 'Smart Factory' using private ethereum blockchain.
Smart Factory uses several sensors: thermometer, hygrometer, accelerometer and so on.
I am currently curious about three things.
Numerous values measured by a sensor, for example an accelerometer measure 100 data per second for 10 minutes.
It is 60,000 data, and the data volume will be about 20mb (assumption).
Is it possible to store all of this data on all nodes of the ethereum blockchain at this time? Or can I just read the sensor value and do a simple command (raise the temperature in indoor, stop the machine and so on)? This is because the data is stored like an excel file, not as simple as the transaction data.
More simply, is it possible to store 'file data' in a block such as an excel file in an ethereum blockchain?
There is no need for 'ether trading' in the private ethereum blockchain that I envision. 'gas' prevents malicious users from falling into an infinite loop, but what does 'Ether' do in the case of me?
I am a complete starter. Ultimately, I'd like to implement a smart factory using few sensors(it's for PPT presentations, not for real), but knowledge has too many limitations.
Thank you so much for your answer to my question.
(I use this site for the first time. I posted the same question on stackoverflow. Is this wrong?)
