[ZcF-general] January udpate

[Dov Gordon]

**Project update for project #36: An alternative approach to analyzing 
anonymity in cryptocurrencies February Update: * **

Tasks completed:

-- We have identified an extension of the base protocol that will allow 
the desired trade-off between round complexity and the number of mix-ins 
in the ring signature.

-- We have begun proving the security of this extended protocol.


Issues to address

-- We need to address how increased communication rounds can be 
incorporated into the blockchain without requiring as many blocks as we 
have communication.  (I.e. we would like to keep some of this 
communication “off chain.”)

-- We need to consider the implications of our security definition. 
  What are the weaknesses and strengths?

-- We will begin writing up our results for publication.
