Everyone who is part of a project should be able to add infos on a token, display them with an icon (warning?) If the copiosa team doesn't had contact with them (like an official meeting).

This can be a way to attract project who want to be verified.

Accept all submission for a certain fee in the token they want to verify, this way you avoid spam and generate a small revenue.

You can design this as a challenge when you already know the official addr of a project team.

If there is a lot of submission you go by vote and add the ability to view all submission.
