Solana Sandwich 机器人威胁：Jito 保护用户

随着 Solana 的日益普及，三明治机器人也出现了，它们利用交易来获取利润。为了解决这个问题，MEV 基础设施公司 Jito 开发了一种解决方案，用户只需支付象征性的费用即可保护他们的交易免受三明治攻击。这项服务受到了广泛关注，用户支付了超过 930 万美元的费用来保护他们的交易。此外，Solana 基金会采取了严格的立场，承诺删除参与恶意三明治攻击的验证者。

Solana's Sandwich Bot Scourge: Jito Steps in to Protect Users

Solana 的三明治机器人灾难：Jito 介入保护用户

Within the vibrant and rapidly expanding Solana ecosystem, a sinister threat has emerged: sandwich bots. These malicious programs exploit the network's transaction processing mechanisms to execute profitable trades at the expense of unsuspecting users. However, a solution is at hand as Jito, a prominent Solana MEV (maximal extractable value) infrastructure provider, rallies to the community's defense.

在充满活力且快速扩张的 Solana 生态系统中，出现了一种险恶的威胁：三明治机器人。这些恶意程序利用网络的交易处理机制来执行有利可图的交易，而牺牲了毫无戒心的用户的利益。然而，随着著名 Solana MEV（最大可开采价值）基础设施提供商 Jito 团结起来为社区辩护，解决方案已经出现。

The Insidious Nature of Sandwich Bots

三明治机器人的阴险本质

Sandwich bots capitalize on the high transaction volume on Solana, which has surged in recent months due to the platform's memecoin frenzy and token airdrop deluge. These bots monitor the network for users purchasing tokens, then place large orders ahead of them, driving up the token's price. After the victim's trade is processed, further inflating the price, the bots sell their tokens for a substantial profit.

三明治机器人利用了 Solana 的高交易量，近几个月来，由于该平台的 memecoin 狂热和代币空投泛滥，交易量激增。这些机器人监控网络中是否有用户购买代币，然后在他们之前下大订单，从而推高代币的价格。在处理受害者的交易后，进一步抬高价格，机器人出售其代币以获得可观的利润。

Jito's Private Transaction Pool: A Sanctuary for Traders

Jito的私人交易池：交易者的避难所

Recognizing the detrimental impact of sandwich bots on user experience and the long-term health of the Solana network, Jito has developed an innovative solution. The company offers users the option to execute their trades through a private transaction pool by paying a modest tip, typically around $0.04 per trade during normal network conditions.

认识到三明治机器人对用户体验和 Solana 网络的长期健康产生的不利影响，Jito 开发了一种创新解决方案。该公司为用户提供通过私人交易池执行交易的选项，只需支付适度的小费，通常在正常网络条件下每笔交易约为 0.04 美元。

Once a user pays Jito, their transaction is incorporated into a private bundle processed by a Jito validator, software entities responsible for processing transactions on Solana. This process shields transactions from malicious MEV bots, preventing them from identifying and exploiting them before execution.

一旦用户向 Jito 付款，他们的交易就会被纳入由 Jito 验证器（负责在 Solana 上处理交易的软件实体）处理的私有包中。此过程可保护交易免受恶意 MEV 机器人的攻击，防止它们在执行前识别和利用它们。

The effectiveness of Jito's solution is evident in the overwhelming response from users, who have paid over $9.3 million worth of SOL in tips over the past week to safeguard their trades. As Solana's trading volume continues to grow, Jito's revenue potential is expected to soar.

Jito 解决方案的有效性从用户的强烈反应中可见一斑，他们在过去一周支付了价值超过 930 万美元的 SOL 小费来保护他们的交易。随着 Solana 交易量的持续增长，Jito 的收入潜力预计将飙升。

Understanding 'Good' MEV: A Balancing Act

理解“好的”MEV：平衡之举

It is important to note that not all MEV practices are malicious. According to Jito Community contributor Lucas Bruder, arbitrage and other forms of MEV, such as DeFi liquidations, can contribute to the stability and efficiency of markets.

值得注意的是，并非所有 MEV 做法都是恶意的。 Jito 社区贡献者 Lucas Bruder 表示，套利和其他形式的 MEV（例如 DeFi 清算）可以有助于市场的稳定性和效率。

Arbitrageurs exploit price disparities between exchanges to generate small profits, maintaining accurate pricing and ensuring fair market conditions for Solana users.

套利者利用交易所之间的价格差异来赚取微薄利润，维持准确的定价并确保 Solana 用户的公平市场条件。

Network Support and Enforcement

网络支持和执行

The Solana Basis, a non-profit organization dedicated to the decentralization, adoption, and security of Solana, has taken a hardline stance against malicious MEV practices.

Solana Basis 是一家致力于 Solana 的去中心化、采用和安全的非营利组织，对恶意 MEV 做法采取了强硬立场。

In a recent announcement, Tim Garcia, a validator relations lead at the Solana Basis, declared that operators engaging in malicious sandwich attacks or other actions that harm Solana users will not be tolerated.

在最近的一份声明中，Solana Basis 验证者关系负责人 Tim Garcia 宣称，不会容忍从事恶意三明治攻击或其他伤害 Solana 用户的行为的运营商。

The organization operates a validator delegation program that provides support to individuals running validators, ensuring their profitability and network stability. Garcia emphasized that validators engaging in malicious practices will be "instantly and permanently removed" from the program, with enforcement measures commencing within 24 hours.

该组织运营一个验证器委托计划，为运行验证器的个人提供支持，确保其盈利能力和网络稳定性。加西亚强调，参与恶意行为的验证者将“立即并永久地从该计划中删除”，并在 24 小时内开始采取强制措施。

Alternative Measures: RPC Customization

替代措施：RPC 定制

In addition to Jito's solution, users can also mitigate the risk of sandwich attacks by switching to custom RPCs (Remote Procedure Calls), which allow them to send transactions to different blockchains. However, this process can be complex, especially for less experienced users. Jito's solution offers a simpler and more accessible alternative, integrated into popular trading platforms such as the Jupiter Aggregator browser app and several major wallets.

除了 Jito 的解决方案之外，用户还可以通过切换到自定义 RPC（远程过程调用）来降低三明治攻击的风险，这允许他们将交易发送到不同的区块链。然而，这个过程可能很复杂，尤其是对于经验不足的用户而言。 Jito 的解决方案提供了一种更简单、更易于访问的替代方案，集成到流行的交易平台中，例如 Jupiter Aggregator 浏览器应用程序和几个主要钱包。

Solana's Unique Vulnerability

Solana 的独特漏洞

Sandwich bots are not exclusive to Solana; they plague other public blockchains, including Ethereum. However, Solana is particularly susceptible due to its lower transaction fees, enabling bots to target a higher proportion of trades.

三明治机器人并不是 Solana 独有的。它们困扰着其他公共区块链，包括以太坊。然而，Solana 特别容易受到影响，因为它的交易费用较低，使机器人能够瞄准更高比例的交易。

Moreover, the prevalence of memecoins on Solana, assets often characterized by low liquidity, exacerbates the problem. Low liquidity assets experience significant price fluctuations when traded, creating ample opportunities for sandwich bots.

此外，Solana 上 memecoin 的盛行（通常以低流动性为特征的资产）加剧了这一问题。低流动性资产在交易时会经历显着的价格波动，为三明治机器人创造了充足的机会。

Community Sentiment and Consensus

社区情绪与共识

The Solana community is actively seeking a social consensus to discourage support for actors who target users with sandwich attacks. This process aims to foster alignment among community members and identify those who prioritize the integrity and safety of the network.

Solana 社区正在积极寻求社会共识，以阻止对针对用户进行三明治攻击的行为者的支持。此过程旨在促进社区成员之间的协调，并确定那些优先考虑网络完整性和安全性的人。

Conclusion

结论

Jito's emergence as a protector of users against sandwich bots on Solana is a testament to the platform's ongoing efforts to ensure a fair and secure trading environment. The company's innovative solution, combined with the Solana Basis's commitment to combating malicious MEV practices, provides a glimmer of hope in an environment often plagued by predatory tactics.

Jito 成为 Solana 上用户免受三明治机器人侵害的保护者，证明了该平台为确保公平和安全的交易环境所做的持续努力。该公司的创新解决方案与 Solana Basis 打击恶意 MEV 行为的承诺相结合，为经常受到掠夺性策略困扰的环境带来了一线希望。
