A Complete Guide to Coin Mixers
This guide aims to help you navigate the virtual currency space,providing insights into one of the trending techniques revolutionizing the privacy aspect of crypto transactions – the crypto coin mixer.
What Are Coin Mixers?
Imagine trying to find a penny you threw into a bucket full of similar pennies. Of course, it’s the same amount of money, but it isn’t your specific coin. Also, you have no way of identifying whose penny you end up picking up from the bucket. That is the idea of crypto mixers in general.
Crypto mixers are services that hide transactions on the blockchain. They mix multiple users’ cryptos to hide their origins, providing more privacy than standard blockchain transactions. We understand that blockchains are great for security and help make transactions transparent for all to see. A crypto mixer, however, disrupts that transparency. It is vital to note that this service doesn’t replace the blockchain network.
Also referred to as the tumbler, as it “tumbles” multiple coins in a random order, the crypto mixer, mixes different cryptocurrency tokens within the ‘mixer technology’ and sends them to the receiver’s address. The transaction is highly encrypted and the service charges a fee between 0.1 and 3% for the service.
This coin-mixing technique is available to users who want to make transactions while concealing the identities of the associated addresses.
How Do Coin Mixers Work?
Crypto mixers help to anonymize your transactions, making it difficult for anyone to track them. It’s similar to having a stack of cash in an envelope without your name or address to be delivered to a loved one. Your loved one will receive the money, but they won’t pinpoint who or where it came from.
Here’s a simple breakdown of how these mixer services anonymize your transactions:
- Phase 1: A user sends their preferred crypto (Bitcoin, Ethereum, etc.) to a specified address provided by the mixer service.
- Phase 2: Once the coins reach the coin mixer’s wallet, they join a pool of funds from other users. This pool is like a giant bucket in which all the coins are mixed.
- Phase 3: The mixer swings into action. It sends the mixed cryptos from this pool to recipients’ wallets in multiple transactions. Take note; they aren’t your exact coins but a mix of someone else’s.
- Phase 4: The coin’s original transaction trail is broken, making it difficult for anyone to track where the funds came from. It appears someone sent the money to a mixer, and separate transactions went out to different recipients.
Voila! No one can link the cash tokens you transferred to a mixer wallet to the ones that moved from that wallet to your recipients.
The Technology Framework of Coin Mixers
Coin mixers deploy smart contracts for placing the tokens and tumbling them. They also use another way to anonymize transactions: by implementing Zk-SNARK or zero-knowledge protocol. This is over and above the cryptographic underpinning and the blockchain mainstay.
A crypto mixer uses different operational models, such as centralized and decentralized. The centralized process uses private third-party services or networks trusted by the user, while decentralized mixing uses a peer-to-peer method with automated mixing. Replace the third party with a smart contract, and that’s the underpinning of a Bitcoin mixer!
Centralized Bitcoin mixers pool users’ funds in proprietary coin wallet addresses, where they mix them with other users’ funds and redistribute them. Decentralized mixers rely on protocols like CoinJoin, to deploy open-source, automated permissionless mixing by merging funds in a single large transaction, before routing to the destination addresses.
Pros and Cons of Coin Mixers
Crypto mixers are discrete in anonymizing users’ crypto dealings. However, there are two sides to every “coin”. The table below briefly outlines the perks and disadvantages of these services.
| Pros | Cons |
|---|---|
| Mixers help hide the origin and destination of your crypto transactions | Mixers are often associated with illegal activities, which can raise suspicion from government authorities |
| Hackers are less likely to target you based on your untraceable spending habits | They are third-party services, so trusting them with your funds can be risky |
| Users have a degree of control over how their coins are mixed | They are difficult to set up and process transactions longer |
| You can enjoy increased privacy for all your transactions |  |
| They are user-friendly, and users can engage with them without needing assistance. | |
Why coin mixers are a “hot” thing now？
Coin mixers allow secure and private transactions of any sizes and coin types. The built-in privacy features and anonymity allows users to work around the privacy flaw of the Bitcoin blockchain to mask the identity of sender and recipient in the blockchain ledger.
The idea of a Bitcoin tumble follows the premise that intermixing Bitcoin through a black box makes it difficult to identify the person who has involved. This is a great feature for those who want to hide their wallet addresses and amount of transactions or coin types.
A user who looks for privacy can send his tokens to a software company who is like a middleman that mixes and tumbles his coins with other depositors’ coins. The mixer then transfers an equal amount of mixed coins to the designated receiver without either sender or receiver being associated in any way. A sure way to mask any digital footprints!
Example
To better understand the coin mixer concept, let us take the example of a political party or campaign that often receives anonymous donations. Instead of direct donations, funds of donors can be pooled, and a third party designated to complete the actual transaction. As a result, the charity receives the donation while the donor identity remains anonymous.
Say, sender A wants to send 50 Bitcoins to the political party B. A uses a coin mixer for a peer-to-peer payment. A visits the platform and enters B’s destination address. A then deposits 1,000 Bitcoins into the mixer wallet and selects a mixing duration, of say 3 hours to a maximum of 20 hours.
B receives the coins in their party’s wallet after 15 hours, following a deduction of mixing fee.
Flipstarter is a current rage to raise funds privately and safely using Bitcoin cash. While it may be ideal for P2P crowdfunding of projects and collaboration on campaigns, the coin mixer is much more than that. It allows combining coins other than Bitcoins and obscuring their origins to hide all traces of the addresses.
Thus, in addition to fundraising, coin mixers offer a safer and anonymous environment for making payments of all sizes and coin mixes.
Bottom Line
Forget about blockchain transaction trails and explore the world of crypto mixers. These secret agents disrupt the public ledger, making it difficult for your transactions to be traced. While they offer privacy, there are legal gray areas and risks to consider. Consequently, it is essential to weigh their perks and drawbacks and your need for anonymity.
There is no doubt that crypto mixers offer a glimpse into the future of anonymous finance. However, it is vital to research and understand their legal implications before implementing them fully into your crypto dealings.
