BNB链引入MEV保护，以保护Defi用户免受三明治攻击

分散的金融（DEFI）生态系统正在见证最大可提取价值（MEV）攻击的激增，尤其是三明治攻击，这造成了加密货币交易者的重大财务损失。作为回应，BNB连锁店引入了一种创新的MEV保护机制，以保护用户免受这些恶意做法的影响，从而提高了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.

本文强调了最大可提取价值（MEV）攻击（尤其是三明治攻击）在分散的金融（DEFI）领域的越来越多的患病率，本文探讨了BNB链条采取的措施，以保护其用户免受这些恶意行为的侵害。具体而言，我们研究了三明治攻击的概念，以及BNB链的MEV保护机制如何运作以提高Fefi交易的安全性和效率。

Understanding Sandwich Attacks in the Crypto Domain

了解加密货币域中的三明治攻击

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.

在分散财务的领域中，三明治攻击是一种前进技术，由恶意机器人执行，以操纵分散交易所（DEXS）的加密货币价格。这些机器人巧妙地将两笔交易围绕交易者的交换订单放在DEX上，有效地操纵了所交易资产的价格。这种操作通常不会受到用户的注意，导致价格滑倒和贸易执行不佳，最终导致财务损失。

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.

为了应对这一日益增长的威胁，BNB连锁店引入了MEV保护，与领先的钱包提供商和私人交易服务联手为其用户创造了安全的交易环境。该倡议旨在保护用户免受三明治攻击的影响，并提高Defi交易的整体安全性。
