Very interesting.

Do you envision (let's say the V1 of) this system to serve primarily on Web 2 media or Web 3 media?

It would seem that in order to siphon users from Web 2 it would need to serve on Web 2 media. Wed 2 media / user attention today is monopolized by gated publisher platforms and tech giants. So for this to work does it require the Google/FB/Twitters of the world to use this system to serve ads (and why would they)?

As a Web 3 -> Web 3 ads system (or as a precondition for economically viable Web 3 media to exist) I get it. The Web 2 -> Web 3 part seems fussier
