Understanding CoinJoin: A Decentralized Privacy Protocol

了解 CoinJoin：去中心化隱私協議

CoinJoin, introduced by Bitcoin Core developer Greg Maxwell in 2013, allows multiple users to combine their transactions into a single one, effectively obscuring the origin and destination of Bitcoin. Unlike tumblers, CoinJoin operates without a centralized mixing service, eliminating the risk of theft or subpoena.

CoinJoin 由比特幣核心開發人員 Greg Maxwell 於 2013 年推出，允許多個用戶將他們的交易合併為一筆交易，從而有效地掩蓋了比特幣的起源和目的地。與不倒翁不同，CoinJoin 的運作無需集中混合服務，從而消除了盜竊或傳票的風險。

Advantages of CoinJoin Over Bitcoin Tumblers

CoinJoin 相對於比特幣玻璃杯的優勢

Decentralized and Trustless: CoinJoin's decentralized nature ensures that users don't need to rely on a third party to mix their coins, providing enhanced security and peace of mind.

去中心化和去信任化：CoinJoin 的去中心化性質確保用戶不需要依賴第三方來混合他們的硬幣，從而提供增強的安全性和安心。

Cost-Effective: Unlike tumblers, CoinJoin only requires users to pay a small fee to miners to include their transactions in the next block, making it a more affordable option.

成本效益：與tumblers不同，CoinJoin只需要用戶向礦工支付少量費用即可將其交易包含在下一個區塊中，使其成為更實惠的選擇。

Limitations of CoinJoin

CoinJoin 的局限性

Wallet Compatibility: Not all Bitcoin wallets currently support CoinJoin, potentially requiring users to switch wallets to use it.

錢包相容性：目前並非所有比特幣錢包都支援 CoinJoin，可能需要用戶切換錢包才能使用它。

Transaction Size and Confirmation Times: CoinJoin transactions can be larger than regular ones, leading to longer confirmation times and higher fees.

交易規模與確認時間：CoinJoin 交易可能比常規交易更大，從而導致確認時間更長且費用更高。

Anonymizing Bitcoin vs. Privacy Coins: Which Is Better?
