Bonding the Anonymous

This may sound like a joke but I think that there are variations of this idea that solve real problems.

Suppose that various official and well known unofficial certificate authorities (CAs) decide to issue pseudonymous certificates (PCs) under the following rules:

A masked man walks into the CA office and presents a $50 bill and a public key PK. The CA issues a PC identifying PK, the amount and the issuer.
The $50 is burned.
The issued cert specifies that the cert cost $50.

Another part of the scheme is the SOB data bases of certificates of SOBs maintained by various people and organizations.

The purpose is to bootstrap reputations. The purpose of the data base is to collect reports of defections. It is vaguely like a bank spending money to build impressive offices. It convinces potential depositors that the bank will probably still be there next month.
