Now the sucker who "buys" from C has the problem of tracing authenticity of the "title" C is selling. This is not easy, particularly if B is less than scrupulous and has "sold" title to a number of folk including C, or if C is unscrupulous and is "selling" without have concluded and transaction with B.
This can easily be solved in a number of ways. For example, a public key could be publicly associated with each address. A transfer is accomplished by signing a message to that effect. Similarly -- and very importantly -- control over routing of that address is also governed by that private/public key pair. There's more to this protocol than I've described, but it can be made to work.
