The information provided below is for discussion on technology and privacy protection only. It does not constitute any advice on illegal behavior, nor does it encourage the use of privacy technology for money laundering, tax evasion or other illegal activities. Different countries have different regulations on cryptocurrencies. Please be sure to comply with local laws and regulations when using them. The following are some cryptocurrency wallets and platforms that are widely discussed publicly and sell enhanced transaction privacy. However, it should be noted that privacy protection technology is not foolproof and many system designs may also be subject to regulatory requirements: 1. Wasabi Wallet • Mainly used for Bitcoin, it integrates CoinJoin mixing service, which can obfuscate the source of transactions to a certain extent. • The community recognizes its design in improving user privacy, but transaction records are still visible on the blockchain, but it is difficult to directly link to specific users after mixing. 2. Samourai Wallet • Also based on Bitcoin, it provides a variety of privacy enhancement features, such as CoinJoin, remote nodes, and anti-chain analysis technologies such as "Stonewall". • Emphasize decentralization and privacy, but still need to be cautious when using it, and make a comprehensive judgment on the transaction link. 3. Privacy coin wallets (e.g. Monero wallet) • Privacy coins such as Monero emphasize transaction privacy from their design, using technologies such as ring signatures, shielded addresses, and zero-knowledge proofs to make it difficult for external parties to track information such as the transaction parties and the amount. • Using official or community-approved wallet software can better protect transaction privacy, but it is also limited by the public record nature of the blockchain itself. 4. Zcash wallet (selective privacy) • Zcash supports two transaction modes, transparent and shielded, of which the shielded transaction mode can hide the transaction amount and address. • Setting the privacy level is user-selectable, but the privacy function needs to be carefully configured and its limitations understood before use. It should be noted that: • "Anonymous" transactions do not mean completely untraceable. Existing technologies, on-chain analysis methods, and regulatory measures (including anti-money laundering, KYC requirements, etc.) may break through some privacy protection measures. • The privacy enhancement features provided by many wallets may attract the attention of regulators, especially when large capital flows or abnormal transaction behaviors are involved. • Technical means often exist in a gray area between privacy protection and legal compliance. Users should be extremely cautious when using these tools and understand their legal responsibilities. In short, if you use these wallets for legitimate reasons (such as protecting personal privacy, preventing targeted attacks, etc.), the above tools can be used as objects of understanding; however, if there are high-risk behaviors such as circumventing supervision and illegal transfers, it is recommended to act with caution and consult professional legal advisors.
