I suppose I should really study her credential system, but I don't see how
any system can keep me from buying a domain name, and then give you
effective control over it. I give you authority to use my secret key for
transactions with regard to that domain name without revealing it to you.
The rest is standard contracting. The mechanisms could either be automated
or manual.
If such contracts are legal, they can be enforced through the courts. If
they are illegal, they can be enforced the way drug and Mafia contracts are
enforced.
