Internet Society: Cryptocurrency probably not an identity system


Impedance Mismatch?

If I'm not misunderstanding something, most cryptocurrencies aim to be "digital cash." I.e., fungible and anonymous. One bitcoin is like any other bitcoin, apart from an identifying number. Much like a banknote. They can be tracked, but only with difficulty. You can say that a particular one passed from A to B but not know any of the intermediate steps. Some are more anonymous and some are less anonymous.

It doesn't seem to me that cryptocurrencies are a natural fit to identity. Or that blockchain technology in general is, either. It hardly seems worth the effort of bodgeing stuff onto a blockchain to allow it to deal with identities. But maybe I'm missing something.
