Hey @todorovv I remember reading Blockchain: Blueprint for a New Economy by Melanie Swan when I started up with crypto. Might be worth a read.
Well in all honesty, if every node in the network perishes, the monitoring data will too. If you mean for some reason the network comes to a halt, data would cease to update as no transactions can get across.
Having a backup list and treating each sensor as nodes to gain remote access to might be a viable solution. May just be a case of changing configuration files to work with a new network or server etc.
But this project was only a concept with a small prototype to demonstrate a use case. Thanks for your question and I look forward to hearing more from you too.
Thank you @momosan I will check the book and share thoughts.
