A bitcoin mixer is a service that allows users to anonymize the movement of funds between wallet addresses. This is especially important for businesses and high-net-worth individuals who value their privacy.
Mixers make it difficult for observers to link a user’s wallet addresses and determine whether they have done anything wrong. They do this by mixing users’ coins and delaying transactions.
Whirlpool
Whirlpool is a zerolink coinjoin implementation created by the team behind Samourai Wallet. It’s easy to use and mathematically guarantees that no deterministic links exist between inputs and outputs. It also offers market leading post mix spending tools that help you properly follow best spend hygiene after mixing.
Each Whirlpool mix is a collaborative transaction between 5 participants. This means that anyone surveilling the blockchain can’t determine which output corresponds to which input. Furthermore, if you’re mixing multiple times consecutively, each new mix is an additional layer of anonymity.
When you have your pre-mix UTXOs ready to be remixed, they will appear in the UTXOs tab once they receive one confirmation on the blockchain. To get started, simply select the UTXO(s) you want to mix and click “Mix Selected”. Once the process is complete, the Badbank tab will sequester the toxic change (the unmixed coins from your Tx0) until you are ready to deposit again.
Samourai
Designed by a group of privacy advocates, Samourai is a mobile wallet that focuses on security and anonymity. It uses a hierarchical deterministic wallet and an encrypted backup to keep your private keys safe. You can restore your wallet from the 12-word mnemonic seed and passphrase provided by Samourai. This feature allows you to move funds between different devices without the risk of losing them or having them frozen by an exchange.
Samourai uses Whirlpool, a ZeroLink coinjoin implementation that mixes transactions through Chaumian CoinJoin. It also supports Ricochets, a transaction type that adds extra hops to your coins’ path. This will make it harder for chain analysis software to link your UTXOs together.
Another useful feature is Batch Spending, which can save you up to 30% on miner fees. This can be useful for combining several small transactions into one large batch, but it can also allow you to get time-sensitive transactions confirmed more quickly.
Coinomize
Using a bitcoin mixer (also known as a tumbler) can help you protect your privacy and anonymity by obscuring your transaction data on the blockchain. This helps prevent someone from tracking your wallet addresses and transactions, which is important for people who want to avoid the Know Your Customer (KYC) requirements of most Bitcoin exchanges.
Coinomize is a popular bitcoin mixer that offers a variety of features. Its no-logs policy and military-grade encryption ensure your privacy and security. It also automatically deletes order data within 72 hours, and you can manually delete it sooner. It also supports several different languages and has a user-friendly interface.
To use Coinomize, enter your Bitcoin address and select the amount you want to mix. You can then adjust the service fee and transfer delay time to match your needs. You can also earn rewards for referring friends and other users. This bitcoin mixer is free to use, but it has higher fees than some competitors.
CoinJoin
CoinJoin is a privacy-ensuring Bitcoin mixing service that combines transaction inputs from multiple users and returns a set of outputs with identical values. This makes it more difficult to identify the origin of an UTXO, which is a key feature for maintaining anonymity in Bitcoin transactions. However, this method of mixing does have some drawbacks. First, it requires participation from other users, which can cause a delay in the completion of the mixing process. Second, it can cost more than a regular transaction because it requires extra cryptocurrency transactions (called “mining jumps”) to generate the final mix.
Another benefit of CoinJoin is that it does not rely on a third party, like some other mixing services. While it is not foolproof, it does make it harder for chain analysis companies to track the origin of a user’s UTXO. Users can also protect their privacy by following best practices, such as not merging their doxxic change with their mixed coins or using the least amount of UTXOs when sending payments.
