Feels a bit dumdum to ask but... can someone explain cashu to me? What I think I understand is... it's another L2 solution similar to lightning but is more anonymous than lightning? Does it similarly work on a network of nodes/relays?

Can someone shed some light on how the whole minting process works? (When I try to claim an... invoice?... it says to add a trusted mint... since when were bitcoiners ok with "trusting"?!)

Also, what parts of the cashu workflow are anonymous and what parts are exposed to third parties?
