Jupiter 推出 Jito 捆绑包，保护用户免受 MEV 攻击

Jupiter 致力于增强用户免受 MEV 攻击的安全性，在其交换功能中实施了 Jito Bundles Tipping。这种机制可以向 MEV 搜索者隐藏用户的交易，直到这些交易被安全地记录在 Solana 区块链上，从而防止 DeFi 中普遍存在的操纵尝试造成潜在的财务损失。

Jupiter Unveils Jito Bundles Tipping to Safeguard Users from Miner Extractable Value Attacks

Jupiter 推出 Jito 捆绑包，保护用户免受矿工可提取价值攻击

In an effort to bolster user protection against Miner Extractable Value (MEV) attacks, Jupiter, a leading decentralized finance (DeFi) platform, has introduced a groundbreaking feature known as Jito Bundles Tipping. This unique service aims to shield users from potential losses resulting from MEV attacks, which have become increasingly prevalent within the DeFi ecosystem.

为了加强用户保护，抵御矿工可提取价值 (MEV) 攻击，领先的去中心化金融 (DeFi) 平台 Jupiter 推出了一项名为 Jito Bundles Tipping 的突破性功能。这项独特的服务旨在保护用户免受 MEV 攻击造成的潜在损失，这种攻击在 DeFi 生态系统中变得越来越普遍。

Unveiling MEV and Its Impact on Transactions

揭秘 MEV 及其对交易的影响

MEV refers to the economic advantage miners or validators can obtain by selectively including, excluding, or reordering transactions within the blocks they produce. This ability allows them to manipulate transaction execution to their advantage, potentially harming ordinary users.

MEV 是指矿工或验证者通过选择性地包含、排除或重新排序其生成的区块内的交易而获得的经济优势。这种能力使他们能够操纵交易执行以达到自己的优势，从而可能损害普通用户。

The Perils of MEV for Ordinary Users

MEV 对普通用户的危险

For ordinary users, MEV attacks can manifest in various adverse scenarios, including:

对于普通用户来说，MEV 攻击可以体现在各种不利场景中，包括：

• Increased Slippage in Trading: Miners may capitalize on user transactions by reordering them to execute a profitable trade before the user's transaction can be completed, leading to higher transaction costs.
• Sandwich Attacks: In sandwich attacks, miners intercept a user's swap transaction, placing their own trades before and after the user's. This results in substantial financial losses for the unsuspecting user.

The Transparency Problem and Its Impact

交易滑点增加：矿工可能会通过在用户交易完成之前重新排序用户交易来执行有利可图的交易来利用用户交易，从而导致更高的交易成本。 三明治攻击：在三明治攻击中，矿工拦截用户的掉期交易，将自己的掉期交易放入在用户之前和之后进行交易。这会给毫无戒心的用户带来巨大的经济损失。透明度问题及其影响

While blockchain technology prides itself on transparency, this very virtue enables MEV operations to be carried out. By providing visibility into all transactions on a blockchain, miners and validators gain the ability to identify and exploit profitable opportunities.

虽然区块链技术以其透明度而自豪，但正是这一优点使得 MEV 操作得以进行。通过提供对区块链上所有交易的可见性，矿工和验证者能够识别和利用盈利机会。

Jito Bundles Tipping as a Solution

Jito 捆绑小费作为解决方案

Recognizing the need for user protection, Jupiter has introduced Jito Bundles Tipping as a countermeasure against MEV attacks. This feature works by diverting user transactions away from public Remote Procedure Calls (RPCs) and directly to a Jito Validator.

认识到用户保护的必要性，Jupiter 推出了 Jito Bundles Tipping 作为针对 MEV 攻击的对策。此功能的工作原理是将用户事务从公共远程过程调用 (RPC) 转移到直接到 Jito 验证器。

How Jito Bundles Tipping Functions

Jito 如何捆绑小费功能

The Jito Bundles Tipping mechanism employs the following steps to protect user transactions:

Jito Bundles 小费机制采用以下步骤来保护用户交易：

1. Transaction Submission: Users initiate their swap transaction through the Jupiter interface, selecting the 'Jito tip' option.
2. Private Transaction Routing: Instead of broadcasting the transaction via public RPCs, the system redirects it directly to a Jito Validator.
3. Faster Processing: Jito Validators process the transaction efficiently, reducing the risk of exposure to malicious entities.
4. Secure Blockchain Insertion: Once validated, the transaction is securely written into the Solana blockchain, shielding it from potential MEV attacks.

Jupiter's Commitment to User Protection

交易提交：用户通过 Jupiter 界面启动交换交易，选择“Jito Tip”选项。私有交易路由：系统不是通过公共 RPC 广播交易，而是直接将其重定向到 Jito 验证器。更快的处理：Jito 验证器进程有效地进行交易，降低暴露于恶意实体的风险。安全区块链插入：经过验证后，交易将被安全地写入 Solana 区块链，使其免受潜在的 MEV 攻击。Jupiter 对用户保护的承诺

With the launch of Jito Bundles Tipping, Jupiter underscores its unwavering commitment to safeguarding its users from the risks associated with MEV attacks. As the DeFi landscape evolves, Jupiter continues to prioritize innovation and user protection, ensuring a secure and transparent trading experience.

随着 Jito Bundles Tipping 的推出，Jupiter 强调了其保护用户免受 MEV 攻击相关风险的坚定承诺。随着 DeFi 格局的发展，Jupiter 继续优先考虑创新和用户保护，确保安全、透明的交易体验。
