I have been thinking about some projects that could be interesting for Bitcoin, and for our Bitcointalk community, but I often run into the problem: KYC

Most of us agree that KYC is not very good and avoids services that involve it, especially if Bitcoin is present.

With that in mind, I would like to know your opinion:
Do you think there are ways to prove copyright and identities, inside and outside the online world, without KYC?
