比特币玻璃杯长期以来一直是注重隐私的加密货币爱好者的首选。但随着去中心化替代方案 CoinJoin 的出现，许多人想知道传统不倒翁的日子是否已经屈指可数了。

Understanding CoinJoin: A Decentralized Privacy Protocol

了解 CoinJoin：去中心化隐私协议

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 由比特币核心开发人员 Greg Maxwell 于 2013 年推出，允许多个用户将他们的交易合并为一笔交易，从而有效地掩盖了比特币的起源和目的地。与不倒翁不同，CoinJoin 的运行无需集中混合服务，从而消除了盗窃或传票的风险。

Advantages of CoinJoin Over Bitcoin Tumblers

去中心化和去信任化：CoinJoin 的去中心化性质确保用户不需要依赖第三方来混合他们的硬币，从而提供增强的安全性和安心。

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：与tumblers不同，CoinJoin只需要用户向矿工支付少量费用即可将其交易包含在下一个区块中，使其成为更实惠的选择。
