What is a crypto mixer?
Cryptocurrency mixers allow people to mix cryptocurrency funds with huge sums of other funds to keep their transactions private. In addition to anonymizing fund transfers between services, these services do not require Know Your Customer (KYC) checks.
Because of this, employing crypto mixers to launder money or conceal earnings is quite risky. The vast majority of dirty currencies are processed by mixers and online gambling sites. The proportion of illicit Bitcoin (BTC) processed by mixers has consistently been about a quarter every year, while the proportion laundered through exchanges and gambling has remained relatively constant (66 to 72%).
The two types of Bitcoin mixers are centralized and decentralized. For a fee, centralized mixers receive Bitcoin and send back different Bitcoins, providing a simple way to tumble Bitcoins.
With decentralized mixers, transactions are obfuscated using protocols like CoinJoin that utilize either a completely coordinated approach or a peer-to-peer approach (P2P). The protocol lets a bunch of users pool BTC and then redistribute it so everyone gets one. Even so, no one knows who got what or where it came from.
There are also obfuscation-based and zero-knowledge-based coin mixers. Users’ transaction graphs are hidden with obfuscation-based mixers, also called decoy-based mixers. Conversely, an adversary with enough resources can recreate the transaction graph.
The zero-knowledge mixers, on the other hand, use advanced cryptography techniques like zero-knowledge proofs to erase the transaction graph. A big disadvantage is that it requires extensive cryptography which can limit scalability.
What are the types of mixing services?
Mixing services for cryptocurrencies are categorized into two types, custodial and noncustodial.
Custodial mixing happens when users give their tainted coins to a trusted third party, who returns “clean” coins after a while. The problem with this technique is that the users lose their money during the mixing. Consequently, the trusted mixing party may steal funds in the case of custodial mixers.
Noncustodial mixers often use publicly verifiable smart contracts or secure multi-party computation to replace trusted mixing parties. Noncustodial mixing involves two steps.
First, users deposit Ether (ETH) or other tokens into a mixer contract from address A. Following that, they can withdraw their coins via a withdrawal transaction to a new address B after a user-defined period of time.
By using ring signatures and zk-SNARKs in withdrawal transactions, users can confirm to the mixer contract that they deposited without revealing the deposit transaction.
How do cryptocurrency mixers work?
With crypto tumblers or mixers, you run your trade’s digital signatures through a “black box” that conceals them.
Programs that mix up cryptocurrency before transferring it to its designated receivers are called crypto mixers. In a Bitcoin explorer, for instance, it’ll show that person A transferred Bitcoin to a mixer, and that person B received Bitcoin from a mixer. By doing this, nobody knows who sent the BTC to whom. Because of this, dirty Bitcoin gets laundered.
A coin mixer takes your cryptocurrency and mixes it with another cryptocurrency before sending you smaller amounts of crypto to an address of your choice, minus 1-3% of the amount you put in. Coin mixing firms usually make 1-3% profit, which is how they make money.
Coin mixing is comparable to money laundering in that it is criminal conduct. People who mix coins aren’t necessarily committing a crime, just because they do it. It just means they want to make their cryptocurrency transactions more private.
Are these mixers illegal?
It depends on your jurisdiction if you can use coin mixing services. Is it necessary to use Bitcoin mixers? Is tumbling crypto legit? How you use these services depends on your goals.
Former United States Assistant Attorney General Brian Benczkowski says using mixers to disguise crypto transactions is illegal. As an example, Bitcoin’s key feature is privacy not anonymity, so your real identity isn’t always revealed but your transactions can be audited for fraud.
The Financial Crimes Enforcement Network (FinCEN) classifies bitcoin mixers as money transmitters.
Therefore, they must register with FinCEN and apply for a state-by-state license to operate. In 2021, an Ohio citizen was arrested on suspicion of money laundering conspiracy after he ran a Bitcoin mixing service on the dark web. Despite FinCEN’s mandatory licensing requirements, the service operated as an unregistered money-transmitting business.
Can you trace a crypto tumbler or Bitcoin mixers?
Since crypto mixing services pool all the coins together, it’s tough to track specific coins because they’re distributed randomly.
Retailers can rewrite their crypto history with cryptocurrency tumblers by creating custom blockchains based on different currencies. It’s hard for users to link currencies to specific exchanges because they route transactions through a semi-random network. As a result, if coins are tumbled, they cannot be traced.
Bitcoin tumblers and Bitcoin mixers muddle the blockchain of traces of transferred BTC. Even though they both do the same thing, Bitcoin tumbler is for people who trust third parties, while Bitcoin mixer is for people who don’t.
Bitcoin tumbler and mixer BitMix offers anonymous transactions by routing all payments through its own system. Taking advantage of BTC’s anonymity, it makes tracking coins hard.
On the other hand, many tools track cryptocurrency usage by combining public blockchain data with known addresses. To figure out if money laundering is taking place and if currency swaps or mixers are being used, this information is evaluated.
What is a Bitcoin Mixer?
A bitcoin mixer is a service that receives cryptocurrencies from users, pools them, and then sends them to a recipient address. It’s an attempt to hide the transaction trail.
When you use a mixer, your wallet’s address becomes the recipient of any outgoing transactions instead of a specific Bitcoin address. Similarly, when it comes to a recipient’s address, it’s the address of the Bitcoin mixer.
When funds are mixed, the original sources are hidden, making it hard to track down the senders or recipients. Mixers usually charge between 0.5% and 7% of the transaction as service fees which is generally quite low.
How do Bitcoin mixers work?
There’s always a sender and receiver in a Bitcoin transaction. Blockchain explorers make sure everyone can see these details. In a Bitcoin mixer, coins are received from different sources, tumbled, and sent to different parties. In this way, no one can tell who got how much and from whom.
In the blockchain explorer, the recipient will have the sender address as the Bitcoin tumbler. Any sender’s receiving address is also the coin mixer. It gets its name from mixing coins from different users.
Different crypto mixers have different levels of complexity, depending on their infrastructure. Structures with more complexity are more cryptographic dependent. But infrastructure also plays a role in scalability.
Tornado Cash: The famous mixer tied to most crypto hacks
Powered by Ethereum, Tornado Cash (TORN) is a decentralized and non-custodial privacy solution. The Tornado Cash protocol allows users to send ETH and ERC-20 deposits through its smart contract service, based on open source research by the Zcash team (a privacy coin).
In connection with their work with the privacy mixer that “facilitated more than $1 billion in money laundering,” including “hundreds of millions” for North Korea’s Lazarus Group, Tornado Cash developers Roman Storm and Roman Semenov were charged with money laundering and sanctions violations. Storm was already arrested by the DOJ.
After allegations that Lazarus had laundered funds from multiple crypto hacks through the mixer, the US Treasury Department’s Office of Foreign Asset Control sanctioned it last year. Tornado Cash and its operators “knowingly facilitated” money laundering, US Attorney Damien Williams said.
