**Project update for project #36: An alternative approach to analyzing
|
|
anonymity in cryptocurrencies January Update: *
|
|
|
|
Tasks completed
|
|
|
|
-- We constructed a base 2-round protocol that supports n payments from
|
|
n payors to n distinct recipients.
|
|
|
|
-- We found an appropriate noise distribution and sketched a proof that
|
|
our protocol preserves differential privacy: neighboring transaction
|
|
permutations look statistically similar under the noise generated in our
|
|
protocol.
|
|
|
|
|
|
Issues to address
|
|
|
|
-- We haven’t considered malicious payors, or even payors that may abort.
|
|
|
|
-- We plan to explore methods to improve the performance of our base
|
|
protocol at the expense of introducing additional rounds of
|
|
communication. (With the base protocol, the ring signatures involve more
|
|
mix-ins than desired.)
