to hide a signal you need a lot of noise.
if every beep is a signal there is no privacy.
so to build a working privacy-setup,
you need to make it obligatory.
only if noise and signal comes in the same stream
there will be obfuscation.
I get it, but if I learned one thing in the little cryptography that I studied it's:
security thru obscurity is the worst kind of security."Hiding among noise" is not a very good concept.
We will know that we have good mathematical security when we can transact in plain sight, and no longer need to hide, and NSA will
STILL not be able to make sense of it.
What fantastic times we live in! I am looking forward to the next breakthrus in anonymity.... will it come from darkcoin? I hope so.
I believe that masternodes open a very large door of possibilities, and could be asigned a lot of different "jobs" in the future, maybe even different jobs, not all of them doing the same thing etc...

yes obfuscation is not a security itself.
but it is good to shield the main system with an extra layer.
the thing that
I learned in cryptography is that the most successful breaches didnt come thrue the door - they just ignored it.
- eg
https://en.wikipedia.org/wiki/Van_Eck_phreaking // or see
https://en.wikipedia.org/wiki/Tempest_%28codename%29- or the fact that the Russians where able to tell when the CIA or NSA had something big going on, just by monitoring the amount of orders of the pizza-deliverys in special areas.
by dont revealing that an information is an information (it could be just noise) you make Side channel attacks more expensive because you hide who and what to attack.
but i m with you, obfuscation itself should never be the main concept.

if you want to know what a person is realy up to dont look at the files he tries to hide - look at the files he deletes. THAT are the important ones.
