Thank you for the information and the project recommendations! I'll definitely take a look at Datum, Ocean Protocol, and IOTA Data Marketplace.
I'm curious about your thoughts on whether such a network would require individuals to even use their "own" devices or if it would be possible to use manufactured devices from third parties. Do you think it would be feasible to create a system where individuals could still maintain ownership of their data even if they are using third-party devices? Or would it be necessary for individuals to use their own devices in order to maintain control over their data?
Thanks again for your insights and expertise!
