I really like the idea of @Angor for crowdfunding, but I admit I'm also at a bit of a loss to understand how this might work in the real world... Let's say for a non-profit that wants to raise funding for a project... Angor would allow for literally anyone, including anonymous investors, to fund it.

But then any actual organization would need to file taxes and presumably need to know the source of the income... How could this possibly work? Could any organization in the Western world actually be funded exclusively by anonymous Crypto donors?
