Improving Anonymity in Bitcoin with CoinShuffle

Description	Bitcoin's use of pseudonyms (Bitcoin addresses) towards protecting users' privacy has been an attractive feature to many of its adopters. However, due to the inherent public nature of the Bitcoin transaction ledger (the blockchain), Bitcoin does not provide real anonymity in fact. I will present why and how Bitcoin users can be deanonymized. Then I will explain the CoinShuffle protocol, a completely decentralized Bitcoin mixing protocol that allows users to utilize Bitcoin in a truly anonymous manner. The key feature of CoinShuffle is that it is deployable immediately without changing the Bitcoin protocol. Since the protocol introduces only a small computation and communication overhead for its users, it is ready for practical deployment, and several implementations are under way.
