In this section, we build upon Obscuro’s security analysis performed on Coin-Join, CoinShuffle, CoinParty, Xim, Mixcoin, Blindcoin, and TumbleBit in [13]. We expand on their academically proposed Bitcoin mixer comparison by performing the same analysis on the five mixing services included in this study. Coin Theft The five mixers in the study do not have…
In this section, we use the data gathered before regarding current public mixers and our experiments to identify the adoption of academically proposed solutions in ChipMixer, MixTum, Bitcoin Mixer, CryptoMixer, and Sudoku Wallet. The proposed solutions were discussed in before and include CoinShuffle, CoinParty, Xim,Obscuro, Mixcoin, Blindcoin, and TumbleBit. Table outlines which mixing services include…
We provide an overview of experiments conducted on ChipMixer, MixTum, Bitcoin Mixer, CryptoMixer, and Sudoku Wallet. We first describe the methodology, followed by the setup required for the experiments. Then, we outline the interactions made with each of the five services. Finally, we provide both an implementation and security analysis comparing the five selected services…
Comparison Table of popular Btc Tumbling services To begin our analysis of the current mixing service landscape, we gathered a list of 19 centralized mixers. The majority of these tumbling services were posted as service announcements on Bitcointalk, Bitcoin’s main forum created by Satoshi Nakamoto in 2009. Initial coin offerings, new service announcements, and technical…
Bitcoin mixing services have adopted techniques to evade detection and effectively obfuscate user funds. Threats to these services and their user base exist. In response, the Bitcoin community and academic literature have proposed alternative methods to improve trust and eliminate these threats. In this chapter, we discuss the general architecture of four decentralized and four…
Bitcoin mixers, or crypto tumblers, are services offering the ability to obfuscate user’s funds. Figure 3.1 depicts the general functionality of a mixer with three users and the mixing operator. Each user sends their Bitcoin into the service and is returned another user’s input to a different address. This output has a completely different transaction…
