[dpncanyu] Public-key autographs

Of course, the public key of a celebrity can easily be established by printing it (or its fingerprint) on widely sold physical merchandise and memorabilia.

Timestamping could be established by merchandise, too.  Include the fingerprint of a database of autographs on the latest merchendise.  However, without a Bitcoin-like mechanism to transfer ownership, a digital autograph does not become a thing of value, i.e., something which can be sold to others.

Could a celebrity establish a private cryptocurrency solely as memorabilia?  The block chain gets confirmed by people who want to preserve the value of an autograph they own.
