A Bitcoin Mixer is a service that helps you obfuscate your cryptocurrency transactions. These services can be helpful for people who need to obfuscate their transactions for lawful reasons, such as whistleblowers and investigative journalists. This is achieved by mixing your coins with other users’ bitcoins. The mixer then sends the mixed funds to your destination address. The process can be performed with decentralized Bitcoin mixers like Whirlpool, or with custodial wallets like Wasabi Wallet and CoinJoin. Samourai Samourai is a modern mobile Bitcoin wallet hand forged to keep your transactions private your identity masked and your funds secure. It uses the most advanced privacy enhancing technologies on the market to circumvent financial surveillance and data network restrictions. It features a unique’stealth mode’ which uses a passphrase to lock your wallet and prevent screen recording spyware from spying on you while you use your phone. Users are shown a sequence of 12 random words which they must write down and keep somewhere safe (not on their computer or in cloud services). These words, along with the passphrase, can be used to restore your wallet and its balance should it ever be lost or stolen. Samourai also features a built in Whirlpool mix and an awesome post mix spending technique called Stonewall. This allows you to create a transaction that looks like a Coinjoin on the blockchain but in reality is not. This helps to maintain your privacy and avoid undoing the privacy gains from your initial Whirlpool mix. Whirlpool Whirlpool is a popular appliance brand that offers products to help people make their homes more comfortable. Its home automation solutions work with a wide range of ecosystems, including Amazon Alexa and Google Assistant. The company is also an active member of the Matter working group and will add support for its smart appliances when it becomes available. The word whirlpool is often used to refer to a swirling vortex of water, often seen in the sea or river. While many whirlpools appear invisible, some are powerful enough to damage or even destroy ships. Exceptionally dangerous ones are called maelstroms. The share price of Whirlpool has been volatile in recent months, but it is currently trading above its intrinsic value. This is a good sign for an investor, but it’s important to consider the company’s future outlook and value before making a buy decision. Whirlpool is expected to deliver modest growth in the coming years, which doesn’t help build up an investment thesis for the stock. Wasabi Wallet Wasabi Wallet is a non-custodial bitcoin wallet that uses the Tor anonymity network. Its main feature is its CoinJoin implementation, which allows users to mix their coins in a trust-less manner. This provides a level of privacy that is difficult to detect for law enforcement agencies. In addition to its CoinJoin functionality, Wasabi Wallet also includes several other features that make it a great choice for privacy-focused cryptocurrency users. For example, it supports Hierarchical Deterministic Wallets (HD wallets), which allow users to generate an unlimited number of addresses from one seed phrase. It also obfuscates addresses with address reuse avoidance. The Wasabi Wallet uses a custom version of Tor that allows the wallet to use fewer resources, which makes it faster and more reliable than other Tor-based Bitcoin mixing services. The Wasabi Wallet also uses Tor for its backend coordinator server, which is used to verify the blockchain. It takes a while to download the blockchain when first starting Wasabi, but it should be faster on subsequent runs. CoinJoin CoinJoin is a feature offered by many Bitcoin wallets and mixers that helps to keep the private addresses and balances of users anonymous. Unlike tumblers, CoinJoin is not custodial and does not share user funds with others. Instead, it uses a multiparty transaction to mix multiple inputs and outputs so that it is impossible to identify the source of the coins. This method also helps to preserve fungibility, which is essential for the Bitcoin economy. It obscures the relationship between a Bitcoin’s input and its output, making it more difficult for analytics companies like Chainalysis to track transactions and wallets. In addition to offering a wide range of features, the CoinJoin feature in Samourai and Wasabi is very easy to use. Simply unlock your wallet, click on the CoinJoin button, and wait for the process to complete. Once completed, your wallet will lock automatically. The only fees associated with the transaction are the coordinator fee (0.3%) and network mining fees.
