BNB鏈引入MEV保護，以保護Defi用戶免受三明治攻擊

分散的金融（DEFI）生態系統正在見證最大可提取價值（MEV）攻擊的激增，尤其是三明治攻擊，這造成了加密貨幣交易者的重大財務損失。作為回應，BNB連鎖店引入了一種創新的MEV保護機制，以保護用戶免受這些惡意做法的影響，從而提高了Defi Trading的安全性和可靠性。

Highlighting the increasing prevalence of Maximal Extractable Value (MEV) attacks, particularly sandwich attacks, in the decentralized finance (DeFi) domain, this article explores the measures being taken by BNB Chain to protect its users from these malicious practices. Specifically, we examine the concept of sandwich attacks and how BNB Chain's MEV Protection mechanism operates to enhance the safety and efficiency of DeFi trading.

本文強調了最大可提取價值（MEV）攻擊（尤其是三明治攻擊）在分散的金融（DEFI）領域的越來越多的患病率，本文探討了BNB鏈條採取的措施，以保護其用戶免受這些惡意行為的侵害。具體而言，我們研究了三明治攻擊的概念，以及BNB鏈的MEV保護機制如何運作以提高Fefi交易的安全性和效率。

Understanding Sandwich Attacks in the Crypto Domain

了解加密貨幣域中的三明治攻擊

In the realm of decentralized finance, sandwich attacks, a type of front-running technique, are executed by malicious bots to manipulate cryptocurrency prices on decentralized exchanges (DEXs). These bots deftly place two transactions around a trader's swap order on a DEX, effectively manipulating the price of the asset being traded. This maneuver, often unnoticed by the user, results in price slippage and poor trade execution, ultimately leading to financial losses.

在分散財務的領域中，三明治攻擊是一種前進技術，由惡意機器人執行，以操縱分散交易所（DEXS）的加密貨幣價格。這些機器人巧妙地將兩筆交易圍繞交易者的交換訂單放在DEX上，有效地操縱了所交易資產的價格。這種操作通常不會受到用戶的注意，導致價格滑倒和貿易執行不佳，最終導致財務損失。

To counter this growing threat, BNB Chain has introduced MEV Protection, joining forces with leading wallet providers and private transaction services to create a secure trading environment for its users. This initiative aims to safeguard users from sandwich attacks and enhance the overall safety of DeFi trading.

為了應對這一日益增長的威脅，BNB連鎖店引入了MEV保護，與領先的錢包提供商和私人交易服務聯手為其用戶創造了安全的交易環境。該倡議旨在保護用戶免受三明治攻擊的影響，並提高Defi交易的整體安全性。
