Your thoughts:
Using the Blockchain technology to store data records from sensors could be a good way to prevent a lot of cyber-attack as well as well as keep Data unaffected.

My thoughts:

As sophisticated as any technology in the field of security remains less than 80%. The proof was last year (2019) Hackers stole US $ 41 million from the crypto currency exchange from China. But this hack is no worse than last year's crypto market hacking (2018) of US $ 950 million. Theft is carried out on cryptocurrency exchange services to crypto wallets.
