Too Long; Didn't Read
Digital signature — centralized vs. decentralized - is a question of whether it is legitimate or not.

No centralized authority is needed for that, anytime you sign anything with this signature anytime, anytime. And you can sign an electronically signed document on almost any computer; it’s free. But how to prove that this e-signature corresponds to this particular user — it is not possible.
