The Surge in Bitcoin Transactions With Zero Confirmation Charges

零確認費的比特幣交易激增

The cryptocurrency landscape has witnessed a notable trend in the widespread adoption of zero-confirmation transactions, particularly for Bitcoin (BTC) transfers. This practice, while convenient and time-saving, raises concerns regarding its potential impact on the security and integrity of the Bitcoin network.

加密貨幣領域出現了廣泛採用零確認交易的顯著趨勢，尤其是比特幣（BTC）轉帳。這種做法雖然方便且節省時間，但引起了人們對其對比特幣網路安全性和完整性的潛在影響的擔憂。

Zero-confirmation transactions, also known as "unconfirmed transactions," allow users to send BTC without waiting for the transaction to be confirmed by multiple network nodes. This feature expedites payment processing, enabling near-instantaneous transfers. However, these transactions lack the immutability and security guarantees associated with fully confirmed transactions.

零確認交易，也稱為“未確認交易”，允許用戶發送BTC而無需等待交易被多個網路節點確認。此功能可加快支付處理速度，實現近乎即時的轉帳。然而，這些交易缺乏與完全確認的交易相關的不變性和安全保證。

The primary driver behind the rise in zero-confirmation transactions lies in their efficiency and convenience. Merchants and users seeking swift settlement of payments often opt for this method, particularly for small-value transactions. Additionally, the absence of transaction fees associated with zero-confirmation transfers further incentivizes their adoption.

零確認交易成長的主要驅動力在於其效率和便利性。尋求快速結算付款的商家和用戶通常會選擇這種方法，特別是對於小額交易。此外，零確認轉帳無需支付交易費用，這進一步刺激了其採用。

Despite their advantages, zero-confirmation transactions carry inherent risks. The most significant concern is the potential for double-spending attacks, whereby the sender broadcasts a zero-confirmation transaction and then attempts to spend the same BTC elsewhere before the initial transaction is confirmed. In such cases, the second transaction may be accepted by the network, potentially resulting in a loss of funds for the recipient.

儘管零確認交易有其優點，但它也存在固有的風險。最令人擔憂的是雙重支出攻擊的可能性，即發送者廣播零確認交易，然後在初始交易得到確認之前嘗試在其他地方花費相同的 BTC。在這種情況下，第二筆交易可能會被網路接受，這可能會導致接收者損失資金。

Moreover, zero-confirmation transactions are vulnerable to manipulation and fraud. Malicious actors may leverage the lack of confirmation to engage in fraudulent activities, such as initiating chargebacks or claiming that a payment was not received. Such incidents can erode trust in the cryptocurrency ecosystem and deter users from transacting with BTC.

此外，零確認交易很容易受到操縱和欺詐。惡意行為者可能會利用缺乏確認的情況來從事詐欺活動，例如發起退款或聲稱未收到付款。此類事件可能會削弱人們對加密貨幣生態系統的信任，並阻止用戶使用比特幣進行交易。

It is crucial to note that not all zero-confirmation transactions are inherently risky. Reputable exchanges and payment platforms often implement robust risk management systems to mitigate the associated risks. However, individual users who engage in peer-to-peer transactions or utilize lesser-known services should exercise caution and consider the potential consequences of sending BTC via unconfirmed transactions.

值得注意的是，並非所有零確認交易都具有固有風險。信譽良好的交易所和支付平台通常會實施強大的風險管理系統來減輕相關風險。然而，從事點對點交易或使用鮮為人知的服務的個人用戶應謹慎行事，並考慮透過未經確認的交易發送 B​​TC 的潛在後果。

As the adoption of zero-confirmation transactions continues to proliferate, it is imperative for the Bitcoin community to engage in responsible practices and foster a secure and trustworthy environment for BTC usage. Users should carefully assess the risks and benefits associated with this feature before opting for unconfirmed transactions.

隨著零確認交易的不斷普及，比特幣社群必須採取負責任的做法，為比特幣的使用創造一個安全、值得信賴的環境。在選擇未經確認的交易之前，使用者應仔細評估與此功能相關的風險和效益。
