Solana Sandwich 機器人威脅：Jito 保護用戶

隨著 Solana 的日益普及，三明治機器人也出現了，它們利用交易來獲取利潤。為了解決這個問題，MEV 基礎設施公司 Jito 開發了一種解決方案，用戶只需支付象徵性的費用即可保護他們的交易免受三明治攻擊。這項服務受到了廣泛關注，用戶支付了超過 930 萬美元的費用來保護他們的交易。此外，Solana 基金會採取了嚴格的立場，承諾刪除參與惡意三明治攻擊的驗證者。

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

Solana 的三明治機器人災難：Jito 介入保護用戶

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.

在充滿活力且快速擴張的 Solana 生態系統中，出現了一個邪惡的威脅：三明治機器人。這些惡意程式利用網路的交易處理機制來執行有利可圖的交易，而犧牲了毫無戒心的用戶的利益。然而，隨著著名 Solana MEV（最大可開採價值）基礎設施提供者 Jito 團結起來為社區辯護，解決方案已經出現。

The Insidious Nature of Sandwich Bots

三明治機器人的陰險本質

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.

三明治機器人利用了 Solana 的高交易量，近幾個月來，由於該平台的 memecoin 狂熱和代幣空投氾濫，交易量激增。這些機器人監控網路中是否有用戶購買代幣，然後在他們之前下大訂單，從而推高代幣的價格。在處理受害者的交易後，進一步抬高價格，機器人出售其代幣以獲得可觀的利潤。

Jito's Private Transaction Pool: A Sanctuary for Traders

Jito的私人交易池：交易者的避難所

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.

認識到三明治機器人對使用者體驗和 Solana 網路的長期健康產生的不利影響，Jito 開發了一種創新解決方案。該公司為用戶提供透過私人交易池執行交易的選項，只需支付適度的小費，通常在正常網路條件下每筆交易約為 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.

一旦用戶向 Jito 付款，他們的交易就會被納入由 Jito 驗證器（負責在 Solana 上處理交易的軟體實體）處理的私有包中。此流程可保護交易免受惡意 MEV 機器人的攻擊，防止它們在執行前識別和利用它們。

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 解決方案的有效性從用戶的強烈反應中可見一斑，他們在過去一周支付了價值超過 930 萬美元的 SOL 小費來保護他們的交易。隨著 Solana 交易量的持續成長，Jito 的收入潛力預計將飆升。

Understanding 'Good' MEV: A Balancing Act

理解「好的」MEV：平衡之舉

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，並非所有 MEV 做法都是惡意的。 Jito 社群貢獻者 Lucas Bruder 表示，套利和其他形式的 MEV（例如 DeFi 清算）可以有助於市場的穩定性和效率。

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間的價格差異來賺取微薄利潤，維持準確的定價並確保 Solana 用戶的公平市場條件。

Network Support and Enforcement

網路支援和執行

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 是一家致力於 Solana 的去中心化、採用和安全的非營利組織，對惡意 MEV 做法採取了強硬立場。

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.

在最近的聲明中，Solana Basis 驗證者關係負責人 Tim Garcia 宣稱，不會容忍從事惡意三明治攻擊或其他傷害 Solana 用戶的行為的運營商。

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.

該組織運營一個驗證器委託計劃，為運行驗證器的個人提供支持，確保其盈利能力和網路穩定性。加西亞強調，參與惡意行為的驗證者將“立即並永久地從該計劃中刪除”，並在 24 小時內開始採取強制措施。

Alternative Measures: RPC Customization

替代措施：RPC 客製化

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 的解決方案之外，用戶還可以透過切換到自訂 RPC（遠端過程呼叫）來降低三明治攻擊的風險，這允許他們將交易發送到不同的區塊鏈。然而，這個過程可能很複雜，尤其是對於經驗不足的使用者而言。 Jito 的解決方案提供了一種更簡單、更易於訪問的替代方案，整合到流行的交易平台中，例如 Jupiter Aggregator 瀏覽器應用程式和幾個主要錢包。

Solana's Unique Vulnerability

Solana 的獨特漏洞

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.

三明治機器人並不是 Solana 獨有的。它們困擾著其他公共區塊鏈，包括以太坊。然而，Solana 特別容易受到影響，因為它的交易費用較低，使機器人能夠瞄準更高比例的交易。

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（通常以低流動性為特徵的資產）加劇了這個問題。低流動性資產在交易時會經歷顯著的價格波動，為三明治機器人創造了充足的機會。

Community Sentiment and Consensus

社區情緒與共識

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 社群正在積極尋求社會共識，以阻止對針對使用者進行三明治攻擊的行為者的支持。此過程旨在促進社區成員之間的協調，並確定那些優先考慮網路完整性和安全性的人。

Conclusion

結論

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 成為 Solana 上用戶免受三明治機器人侵害的保護者，證明了該平台為確保公平和安全的交易環境所做的持續努力。該公司的創新解決方案與 Solana Basis 打擊惡意 MEV 行為的承諾相結合，為經常受到掠奪性策略困擾的環境帶來了一線希望。
