      Just thought I would mention, on the opposite end of the spectrum here…

      https://github.com/opennamesystem/openname-directory
      https://openname.org/about

      OVERVIEW

      The Openname System (ONS) is a protocol that extends DNS by supporting the registration and resolution of:

      1. user handles on the blockchain (DNS for people)
      2. domains on the blockchain (decentralized DNS)

      …all with full DNS backwards-compatibility.
      ONS = ICANN DNS + blockchain handles + blockchain domains

      ONS currently uses namecoin as a key-value store but the system is blockchain-agnostic.

      I don’t want to add yet another project, but this is something that we need to sort out in time as well.

        Develop a wallet option to have individual addresses for each transaction.

        Mike says he thinks you can’t encrypt the address, in order to make each transaction individual, (he doesn’t explain why), but that we could use the same idea to make transactions more private, without encryption.

        We could just do the “make it easier to have individual addresses” part of private addresses white paper. I can’t quite see how this would work, as my mechanism was to have an extra layer, that the receiver and sender would have access to, via their keys, to show the link behind the encrypted address.

        As with private addresses, if each transaction uses individual addresses then there is much less information leaked. This would make each transaction more like cash, as Satoshi envisaged. It would depend how the individual address could be made and decoded by the wallet whether it would remove the need for a cryptographer to be involved with the software development to make any progress.

                                    Is it possible to add support to the android wallet?

                                    Not sure if that’s required. Buy would any changes be needed to the wallet to make it compatible?
