How Does a Bitcoin Mixer Work? What Is It?

This is how a normal Bitcoin transaction goes down: Wallet is transferred from one crypto wallet to another. It is possible for anybody to see the quantity of Bitcoins exchanged, as well as their origin, by opening a Bitcoin explorer and entering either of the wallet addresses. Individuals whose wallet addresses are known can be readily tracked down using sophisticated methods. This allows complete auditability of your financial dealings. We have previously determined that Bitcoin transactions are not anonymous. Despite being a major selling feature, some Bitcoin users aren't happy with the idea that anybody may use a Bitcoin explorer to access the whole history of their transactions. A Bitcoin tumbler (or "mixer") is essential for those who value secrecy while transacting in crypto.
A Bitcoin mixer is a piece of software (or a service) that receives Bitcoin from many users, shuffles the coins around so that it's impossible to tell who gave how much, and then distributes the money to their respective recipients. If you were to see an outbound transaction from your wallet to a mixer, the explorer would show the mixer's address rather than a Bitcoin address as the beneficiary. Similarly, tracing the origin of coins by entering the address of a transaction's receiver would only provide the address of the coin tumbler. A "mixer" is a wallet that combines the cryptocurrency of many addresses into a single pool from which no individual's money may be recovered. This method allows for entirely anonymous Bitcoin transactions both sending and receiving. These anonymous trades don't always come cheap. In order to use their Bitcoin tumblers, users may be required to pay a charge.
Bitcoin mixers may be broken down into two distinct types: centralized and decentralized. Tumblers function by pooling Bitcoin from numerous users, merging their transactions, or "putting all the money in one huge box and mixing them," so that the coins' origins cannot be traced, and then distributing the funds to their respective recipients. After briefly discussing the two kinds of mixers, we will go on to the mechanics of how each approach operates. In order to explain, we'll use a simplified version of the actual procedure.
A Bitcoin tumbler obfuscates your public key and randomly generates a new public key, breaking the link between your real-world identity and your crypto wallet address.
Bitcoin centralized mixers are third-party applications or websites that do this software for a fee. If you want to utilize a Bitcoin tumbling service, you will need to transfer your Bitcoin to an intermediary address (the mixer's address) instead of the recipient's address. Such tumblers typically provide a form for entering the wallet address of the intended receiver, or the address of the person receiving the coins. After you have sent Bitcoin to the mixer and paid the associated charge, your Bitcoin will be added to a pool and mixed with the Bitcoin of other users. The recipient addresses are then credited with newly-minted coins.
Decentralized mixers operate on a permissionless, borderless, peer-to-peer protocol. In this setup, Bitcoins are tumbled in an automated fashion. Samourai Wallet and Wasabi Wallet (which both have integrated implementations of CoinJoin) are two of the most popular decentralized mixers. When you use a decentralized mixer, your transaction is rolled into a bigger one in which several people pay bitcoins to the same transaction address. All the coins become jumbled up as a result. After a predetermined amount of time, the same quantity of bitcoins will arrive in your receiving wallet, but you will very probably not get the exact bitcoins you deposited. Using a Bitcoin blender that is not decentralized by a central authority has the advantage of often having reduced service fees (since the mixing process is automated). Blender, a centralized mixer, charges between 0.6% and 2.5% of each transaction as a service fee, while Wasabi Wallet charges only 0.3% for transactions involving more than 0.01 BTC (mixing less than 0.01 BTC requires no service fee).
The most prominent perk of employing a Bitcoin mixing service is the increased transactional privacy and anonymity that it provides. However, there are a number of problems with it.
One major problem shared by virtually all Bitcoin mixers is the need to postpone the transaction between the mixer and the final destination address. The goal is to make Bitcoin analysis challenging for even the most astute observers. (Typically, you'll have the option to choose the delay's length.) While delays aren't required, they are favored since they lengthen the difficulty between input and output, making it more challenging to track down the transactions. Bitcoin mixers are a hotspot for money laundering due to the anonymity they provide for crypto transactions, making them a target for authorities. Because of this, several markets refuse to facilitate or severely restrict transactions involving mixed currencies.
The major drawback of a centralized Bitcoin tumbler is that it only has one point of failure because it is managed by a single organization. All pending transactions will be cancelled if the network is shut down. There is always the chance that a hacker or even the centralized mixer may take your money, even if the network doesn't go down. As a further downside, some centralized mixers secretly store both your input and output Bitcoin addresses, putting your privacy at risk if the centralized network is used for anything other than mixing.
Decentralized mixers have the fundamental drawback of requiring a large number of users in order to mix funds, increasing the likelihood that your transactions may be linked back to you.
It is not against the law to use a Bitcoin mixer or any other kind of crypto mixer. However, these methods are sometimes linked to criminal operations like money laundering. The Financial Crimes Enforcement Network (FinCEN) of the United States Department of the Treasury and other organizations have shut down as a result.
Late in 2021, the former CEO of the Bitcoin mixer Helix came clean about having laundered more than $300 million. Not many months before, another Bitcoin mixing business called Bitcoin Fog was allegedly implicated in a money laundering plot. Its purported owner, though, maintained his innocence.
On August 8, 2022, the United States Department of the Treasury blacklisted the Ethereum-based mixer service Tornado Cash due to its usage in the laundering of over $7 billion worth of virtual currency.
There are alternatives to using coin mixing services for those who prefer to keep their crypto transactions under the radar.
More Bitcoin transactions may be handled with the help of the Layer 2 scaling solution Lightning Network, which also improves transaction anonymity. It achieves this by clustering financial dealings, making it harder to track down specific deals.
Using the CashFusion privacy feature, Bitcoin Cash SPV Wallet - Electron Cash provides an option for Bitcoin Cash (BCH) holders (instead of Bitcoin) by making BCH spending and transactions harder to monitor.
Monero (XMR) and Zcash (ZEC) are two privacy currencies that may be used for anonymous purchases. These currencies employ unique privacy features, such protected addresses, to conceal coin transactions within the blockchain. Ring signatures are used by Monero, among other cryptocurrencies, to ensure user anonymity. Consequently, the recipient will be unable to determine which signature belongs to which sender. Note, however, that privacy coins are not universally permissible. South Korea, Australia, and Japan are just a few of the nations that have outlawed cryptocurrencies outright, and as a result, crypto exchanges no longer list them in those countries. Bitcoin, Bitcoin Cash, Monero, and Zcash are all available for trading on CoinUnited.io right now.
Bitcoin transactions may be made anonymously with the use of coin mixing services or Bitcoin tumblers. Governments are tightening down on them due to their usage in unlawful operations and by criminals. If you're concerned about the security of your Bitcoin transactions, Lightning Network may be a better option. Bitcoin Cash and privacy cryptocurrencies like Monero and Zcash are alternatives to explore. If you're set on utilizing a cryptocurrency mixer despite this warning, pick one that complies with local regulations to avoid breaking the law by accident.
