Hmm, this is also a problem for blockchains *if* emails are published in the blockchain (as they currently are in Namecoin).

One solution, then, is to not publish emails in the blockchain, but instead query them from the individual servers, and authenticate those replies via the blockchain. I think that would completely solve the problem (for the blockchain, that is).

Thank you for that observation, I will need to bring this up with the Namecoin team.


Please do not email me anything that you are not comfortable also sharing with the NSA.
