Anyone can explain to me how zeroproof will actually work in a way that i don't have to trust anyone instead of just switching whom i trust?

Aka someone wants to know if i'm over 18, someone needs to verify to that entity that im over 18.

If i now trust a random company to verify me, someone now needs to trust that random company. As usual with Crypto/Bitcoin the trust anker issue is not solved as far as i know.

I always need to trust someone somehow.

Btw. if i understand the blog they do a hard fork which leads again to an additional blockchain and the multi blockchain transaction problem is a hard problem to solve.

Anyone actually working on solving the issues of it or people just prefer to add additional complexity on it?
