Tim Ruffing, Pedro Moreno-Sanchez, Aniket Kate
2014 Lecture Notes in Computer Science  
CoinShuffle is a practical solution for the Bitcoin mixing problem and its distinguishing features are as follows:  ...  We present CoinShuffle, a completely decentralized protocol to allow users to mix their coins with those of other interested users.  ...  We thank Bryan Ford for his insightful comments on an earlier draft and Henry Corrigan-Gibbs for helping us with running the proof-ofconcept implementation on Emulab.  ...

Research on Anonymization and De-anonymization in the Bitcoin System [article]

QingChun ShenTu, JianPing Yu
2015 arXiv   pre-print
Nowadays, there are also some anonymization methods such as coin-mixing and transaction remote release (TRR) to cover the relationship between Bitcoin address and the user.  ...  The Bitcoin system is an anonymous, decentralized crypto-currency.  ...  TRR is a useful exploration, and more research work is expected. (3) The security and practicability of the decentralized coin-mixing protocols have not estimated adequately.  ...

Privacy in decentralized cryptocurrencies

Daniel Genkin, Dimitrios Papadopoulos, Charalampos Papamanthou
2018 Communications of the ACM  
CoinShuffle++ 34 is an extension that uses a P2P network for traffic mixing while significantly reducing the performance and communication bandwidth. Decentralized mixing with large anonymity sets.  ...  Decentralized protocols on the one hand avoid the need for a third party that in practice may become a single point of failure.  ...

Sybil-Resistant Mixing for Bitcoin

George Bissias, A. Pinar Ozisik, Brian N. Levine, Marc Liberatore
2014 Proceedings of the 13th Workshop on Privacy in the Electronic Society - WPES '14  
Users can try to hide this information by mixing, where a participant exchanges the funds in an address coin-for-coin with another participant and address.  ...  It includes a decentralized system for anonymously finding mix partners based on ads placed in the block chain. No outside party can confirm or find evidence of participants that pair up.  ...  We thank Yue Wang for collecting the Bitcoin transaction data.  ...

CoinParty

Jan Henrik Ziegeldorf, Fred Grossmann, Martin Henze, Nicolas Inden, Klaus Wehrle
2015 Proceedings of the 5th ACM Conference on Data and Application Security and Privacy - CODASPY '15  
In this paper, we propose CoinParty a novel, decentralized mixing service for Bitcoin based on a combination of decryption mixnets with threshold signatures.  ...  In consequence, different mixing services have emerged which promise to randomly mix a user's Bitcoins with other users' coins to provide anonymity based on the unlinkability of the mixing.  ...  CoinShuffle improves over Coin-Join by using decryption mixnets for address shuffling which achieves anonymity against insiders.  ...
