How to have your encrypted mail in two places at once

[Mike Ingle]

Why not just write it if you want it? You don't need a team of 
developers, because all the hard stuff (crypto) has been done.

I was thinking of using a blockchain to claim addresses. Confidant Mail 
currently has the problem that anyone can claim any email address, and 
the sender must check the recipient's key ID or signature to make sure 
he's talking to the right person. Why not use a blockchain like 
distributed commit protocol to resolve which key owns what address? The 
original owner would put out the first claim, and then the address 
belongs to him until he signs it over to someone else, just like bitcoins.
