Mixing large amounts of money may be illegal, being in violation of anti-structuring laws. Financial crimes author Jeffrey Robinson has suggested tumblers should be criminalized due to their potential use in illegal activities, specifically funding terrorism ; [4] however, a report from the CTC suggests such use in terrorism-related activities is 'relatively limited'.
Peer-to-peer tumblers appeared in an attempt to fix the disadvantages of the centralized model of tumbling. These services act as a place of meeting for bitcoin users, instead of taking bitcoins for mixing. Users arrange mixing by themselves. This model solves the problem of stealing, as there is no middleman. Such protocols as Coin Join , SharedCoin and CoinSwap allow few bitcoin-users to gather in order to form one bitcoin exchange transaction in several steps.
When it is completely formed, the exchange of bitcoins between the participants begins. Apart from mixing server, none of the participants can know the connection between the incoming and outgoing addresses of coins.
This operation can be carried out several times with different recipients to complicate transaction analysis. Newer and proposed coin implementations such as Cloakcoin , Dash , PIVX and Zcoin have built in mixing services as a part of their blockchain network.
The Zcoin cryptocurrency provides anonymity by using Zerocoin , a type of Zero Knowledge proof method with anonymity sets in the region of thousands, as opposed to the low hundreds for a tumbler. The Zerocoin anonymizing function is built on Bitcoin Core code as an additional layer which allows selective anonymization when required.
The Dark Wallet client software for bitcoin was built to natively mix transactions between users to achieve the same effect without relying on a centralized service. The Monero cryptocurrency provides anonymity without tumbling services due to its privacy centric design, utilizing ring signatures to keep the entire blockchain secure and untraceable.
